RESUMEN

Dysregulation of dopamine systems has been considered a foundational driver of pathophysiological processes in schizophrenia, an illness characterized by diverse domains of symptomatology. Prior work observing elevated presynaptic dopamine synthesis capacity in some patient groups has not always identified consistent symptom correlates, and studies of affected individuals in medication-free states have been challenging to obtain. Here we report on two separate cohorts of individuals with schizophrenia spectrum illness who underwent blinded medication withdrawal and medication-free neuroimaging with [18F]-FDOPA PET to assess striatal dopamine synthesis capacity. Consistently in both cohorts, we found no significant differences between patient and matched, healthy comparison groups; however, we did identify and replicate robust inverse relationships between negative symptom severity and tracer-specific uptake widely throughout the striatum: [18F]-FDOPA specific uptake was lower in patients with a greater preponderance of negative symptoms. Complementary voxel-wise and region of interest analyses, both with and without partial volume correction, yielded consistent results. These data suggest that for some individuals, striatal hyperdopaminergia may not be a defining or enduring feature of primary psychotic illness. However, clinical differences across individuals may be significantly linked to variability in striatal dopaminergic tone. These findings call for further experimentation aimed at parsing the heterogeneity of dopaminergic systems function in schizophrenia.

RESUMEN

A 58-year-old woman was found to have bilateral ptosis and downward gaze deviation immediately after elective shoulder surgery with general anesthesia and supraclavicular nerve block. A code stroke was activated due to concern for the neurologic process, but neuroimaging did not reveal acute changes or vascular abnormality. Her symptoms gradually resolved in the following hours with supportive care and were ultimately deemed to be related to anesthetic and transdermal scopolamine exposures layered upon her underlying comorbidities. Transient bilateral ophthalmoplegia after general anesthetics has been previously described; drug effect should be considered in the differential of this alarming presentation, which can mimic acute stroke and/or Horner syndrome.

RESUMEN

BACKGROUND: The impact of a child s life-limiting or life-threatening illness is significant on parents who experience a great deal of emotional, physical, and spiritual upheaval. Hope has been identified as an important inner resource for parental caregivers. Specifically, parental hope has been described as having four subproceses including Accepting Reality, Establishing Control, Restructuring Hope, and Purposive Positive Thinking. PURPOSE: The purpose of this Delphi study was to gather expert opinions from parents and formal care providers about the four subproceses essential to parental hope, to increase understanding of parental caregivers current support needs. As Phase one of a three-phase study, the findings provided direction in the development of a theory-based hope intervention. DESIGN AND METHODS: A Delphi study consisting of three rounds of survey questions and controlled feedback to experts was employed. Experts suggested strategies for each subprocess and ranked them in order of highest to lowest according to feasibility and effectiveness. RESULTS: Sixty-eight experts consisting of parental caregivers of children diagnosed with life-limiting or life-threatening illnesses and those who care for them (community members, nurses, social workers, and physicians) were recruited to participate. Through three rounds of survey questions, response rates ranged from 92-97%. A consensus revealed eight major themes that support parental hope: Organize Basic Needs; Connect with Others; Prioritize Self-care; Obtain Meaningful Information; Take Things Day by Day; Advocate for Parental Participation; Manifest Positivity; and Celebrate Milestones. PRACTICE IMPLICATIONS: This study identified a wide variety of psychosocial needs for parental caregivers. Results also offered direction for a theory-based hope intervention while highlighting the need for additional research in this area. These results will provide the foundation for a booklet parents can work through in their journey of caring for a child with a life-limiting or life-threatening illness.

RESUMEN

PURPOSE: To conduct a metasynthesis of qualitative research exploring parents' psychosocial experiences during complex and traumatic life transitions related to caring for a child with a life-limiting (LLI) or life-threatening illness (LTI). BACKGROUND: Parents' experiences of caring for a child impacted by an LLI or LTI are not clearly understood, and holistic, comprehensive pediatric nursing care for parents who have children with LLI and LTIs continues to be developed as treatment improves and survival is extended. REVIEW METHODS: Predetermined inclusion and exclusion criteria were used to review qualitative studies. Those included were appraised, classified, and synthesized using systematic procedures guided by Sandelowski and Barroso (2006). DATA SOURCES: A systematic search of qualitative research was conducted by an experienced librarian to identify and retrieve studies from 10 databases. RESULTS: Of the 3515 studies screened, 23 were included. A synthesis of the findings demonstrated that parents experience profound and pervasive uncertainty, leading to their own illness experience being described as a dual reality in which fighting for survival and recognizing the threat of their child's death were daily challenges. Three key processes emerged: the devastation of living with uncertainty, the emergence of hope, and moving forward. CONCLUSION: The integration of findings adds to the current body of knowledge by highlighting the very complex experiences that parents undergo. These findings can support a more comprehensive pediatric nursing plan of care that accounts for the intricacies of the parental experience and the importance of hope.

RESUMEN

Nursing care of families continues to be a challenge within complex and demanding health-care systems. Educational strategies to bridge the theory-practice gap, connecting classroom learning with clinical experiences in undergraduate nursing education, enable students to develop the skills required to form meaningful partnerships with families. This article describes how undergraduate nursing students complete a 15-Minute Family Interview in a clinical practice setting, and document the interview process in a reflective major paper. Students integrate research and theory and identify ways to improve the care of families in the clinical setting while building communication skills and confidence in interacting with families in everyday practice. The implementation of the assignment and the evaluation of the process, including quotes from 10 student papers and 2 clinical faculty members, are discussed. Implications for education and ongoing research are offered.
