Machine learning risk stratification for high-risk infant follow-up of term and late preterm infants.

BACKGROUND: Term and late preterm infants are not routinely referred to high-risk infant follow-up programs at neonatal intensive care unit (NICU) discharge. We aimed to identify NICU factors associated with abnormal developmental screening and develop a risk-stratification model using machine learning for high-risk infant follow-up enrollment. METHODS: We performed a retrospective cohort study identifying abnormal developmental screening prior to 6 years of age in infants born ≥34 weeks gestation admitted to a level IV NICU. Five machine learning models using NICU predictors were developed by classification and regression tree (CART), random forest, gradient boosting TreeNet, multivariate adaptive regression splines (MARS), and regularized logistic regression analysis. Performance metrics included sensitivity, specificity, accuracy, precision, and area under the receiver operating curve (AUC). RESULTS: Within this cohort, 87% (1183/1355) received developmental screening, and 47% had abnormal results. Common NICU predictors across all models were oral (PO) feeding, follow-up appointments, and medications prescribed at NICU discharge. Each model resulted in an AUC > 0.7, specificity >70%, and sensitivity >60%. CONCLUSION: Stratification of developmental risk in term and late preterm infants is possible utilizing machine learning. Applying machine learning algorithms allows for targeted expansion of high-risk infant follow-up criteria. IMPACT: This study addresses the gap in knowledge of developmental outcomes of infants ≥34 weeks gestation requiring neonatal intensive care. Machine learning methodology can be used to stratify early childhood developmental risk for these term and late preterm infants. Applying the classification and regression tree (CART) algorithm described in the study allows for targeted expansion of high-risk infant follow-up enrollment to include those term and late preterm infants who may benefit most.

Prediction of short- and long-term outcomes using pre-operative ventricular size in infants with post-hemorrhagic ventricular dilation.

PURPOSE: Post-hemorrhagic ventricular dilation (PHVD) leads to developmental delays in premature infants, yet the optimal timing of neurosurgical interventions is unknown. Neuroimaging modalities have emerged to delineate injury and follow the progression of PHVD. Fronto-temporal horn ratio (FTHR) is used as a marker of ventricular dilation and can be a standardized tool to direct the timing of neurosurgical intervention. Our study determined a pre-operative FTHR measurement threshold to predict short- and long-term outcomes. METHODS: This is a retrospective cohort study of premature infants with severe intraventricular hemorrhage (IVH) who developed PHVD requiring neurosurgical intervention and were treated in a level IV NICU between 2012 and 2019. Receiver operating characteristic (ROC) curve and area under the curve (AUC) analyses were performed to evaluate the accuracy of pre-operative FTHR for predicting developmental delay. In-hospital outcomes and developmental assessments were analyzed. RESULTS: We reviewed 121 charts of infants with IVH and identified 43 infants with PHVD who required neurosurgical intervention. We found FTHR measurements were an excellent predictor of cognitive and motor delay with an AUC of 0.89 and 0.88, respectively. An average pre-operative FTHR of ≥ 0.67 was also associated with worse lung and feeding outcomes. There was excellent inter-observer reliability of individual components of FTHR measurements. CONCLUSIONS: Early intervention for PHVD is ideal but not always practical. Identification of ventricular size thresholds associated with better outcomes is needed to direct timing of neurosurgical intervention.

The Current State of Neonatal Neurodevelopmental Follow-up Programs in North America: A Children's Hospitals Neonatal Consortium Report.

OBJECTIVE: This study aimed to determine neonatal neurodevelopmental follow-up (NDFU) practices across academic centers. STUDY DESIGN: This study was a cross-sectional survey that addressed center-specific neonatal NDFU practices within the Children's Hospitals Neonatal Consortium (CHNC). RESULTS: Survey response rate was 76%, and 97% of respondents had a formal NDFU program. Programs were commonly staffed by neonatologists (80%), physical therapists (77%), and nurse practitioners (74%). Median gestational age at birth identified for follow-up was ≤32 weeks (range 26-36). Median duration was 3 years (range 2-18). Ninety-seven percent of sites used Bayley Scales of Infant and Toddler Development, but instruments used varied across ages. Scores were recorded in discrete electronic data fields at 43% of sites. Social determinants of health data were collected by 63%. Care coordination and telehealth services were not universally available. CONCLUSION: NDFU clinics are almost universal within CHNC centers. Commonalities and variances in practice highlight opportunities for data sharing and development of best practices. KEY POINTS: · Neonatal NDFU clinics help transition high-risk infants home.. · Interdisciplinary neonatal intensive care unit follow-up brings together previously separated outpatient service lines.. · This study reviews the current state of neonatal NDFU in North America..

Trends in the early care of infants with myelomeningocele in the United States 2012-2018.

PURPOSE: The early care of children with spina bifida has changed with the increasing availability of fetal surgery and evidence that fetal repair improves the long-term outcomes of children with myelomeningocele. We sought to determine current trends in the prevalence and early care of children with myelomeningocele using a national administrative database. METHODS: This is a retrospective, cross-sectional cohort study of infants with spina bifida admitted within the first 28 days of life using the 2012-2018 Healthcare Cost and Utilization Project National Inpatient Database. Patients with spina bifida were identified by ICD code and stratified into a cohort with a coded neonatal repair of the defect and those without a coded repair. This database had no identifier specific for fetal surgery, but it is likely that a substantial number of infants without a coded repair had fetal surgery. RESULTS: We identified 5,090 patients with a coded repair and 5,715 without a coded repair. The overall prevalence of spina bifida was 3.94 per 10,000 live births. The percentage of patients without neonatal repair increased during the study period compared to those with repair (p = 0.0002). The cohort without neonatal repair had a higher risk of death (p < 0.001), prematurity (p < 0.001), and low birth weight (p < 0.001). More shunts were placed in patients who underwent neonatal repair (p < 0.001). Patients without neonatal repair were less likely to have public insurance (p = 0.0052) and more likely to reside in zip codes within the highest income quartile (p = 0.0002). CONCLUSIONS: The prevalence of spina bifida from 2012 to 2018 was 3.94 per 10,000 live births, with an increasing number of patients without neonatal repair of the defect, suggesting increased utilization of fetal surgery. Patients without neonatal repair had a higher risk of death, prematurity, and low birth weight but were more likely to have commercial insurance and reside in high-income zip codes.

Quality improvement sustainability to decrease utilization drift for therapeutic hypothermia in the NICU.

OBJECTIVES: Therapeutic hypothermia (TH) is now standard of care for the neuroprotection of patients with moderate to severe hypoxic-ischemic encephalopathy (HIE). TH misuse results in increased medical complication rates and high health care resource utilization. Quality improvement (QI) methodology can address drift from clinical guidelines. Assessment of sustainability of any intervention over time is an integral part of the QI methodology. METHODS: Our prior QI intervention improved medical documentation using an electronic medical record-smart phrase (EMR-SP) and demonstrated special cause variation. This study serves as Epoch 3 and investigates the sustainability of our QI methods to decrease TH misuse. RESULTS: A total of 64 patients met the diagnostic criteria for HIE. Over the study period, 50 patients were treated with TH, and 33 cases (66%) used TH appropriately. The number of appropriate TH cases between cases of misuse increased to an average of 9 in Epoch 3 from 1.9 in Epoch 2. Of the 50 cases, 34 (68%) had EMR-SP documentation included. Length of stay and TH complication rates did not vary between cases of TH misuse and appropriate TH use. CONCLUSIONS: Our study confirmed a sustained decrease in TH misuse, despite inconsistent use of EMR-SP. We speculate that culture change involving increased awareness of guidelines through education may have contributed more to a lasting change.

The Relationship Between Placental Pathology and Neurodevelopmental Outcomes in Complex Congenital Heart Disease.

Complex congenital heart disease (CCHD) is associated with impaired neurodevelopmental outcomes. Peri- and post-operative factors are known contributors while the impact of the prenatal environment is not yet delineated. Variations in fetal circulation, seen in transposition of the great arteries (TGA) and single ventricular physiology (SVP), are associated with placenta abnormalities. These abnormalities may be associated with placental insufficiency, a risk factor for poor neurodevelopmental outcomes. We hypothesized there is a correlation between placental pathology and impaired neurodevelopmental outcomes in patients with CCHD. We performed a single center retrospective cohort study with patients with TGA and SVP from 2010 to 2017 at Children's Wisconsin. Patient variables were obtained from the medical record. Bayley Scales of Infant Development Third Edition standard scores for cognitive, motor, and language performance were collected from neurodevelopmental visits. Placenta pathology reports were reviewed with tabulation of predetermined anatomical and pathological characteristics. We identified 79 patients in our cohort and 61 (77.2%) had abnormal placentas. There was no significant difference between the two groups in any demographic or clinical variables. For cognitive and motor performance, without adjusting for the covariates, infants with placental abnormalities had significantly lower scores compared to infants without (p = 0.026, p = 0.045 respectively). Conversely, there was no significant difference in language scores between the two groups (p = 0.12). Placenta abnormalities are common in patients with CCHD, and placenta abnormalities are associated with impaired neurodevelopmental outcomes. These results underscore the complex causal pathways of neurodevelopmental impairment in infants with CCHD and offer opportunities for targeted postnatal developmental interventions after discharge.

Survey of Quaternary Neonatal Management of Posthemorrhagic Hydrocephalus.

OBJECTIVE: This study aimed to determine clinical care practices for infants at risk for posthemorrhagic hydrocephalus (PHH) across level IV neonatal intensive care units (NICUs). STUDY DESIGN: Cross-sectional survey that addressed center-specific surveillance, neurosurgical intervention, and follow-up practices within the Children's Hospitals Neonatal Consortium. RESULTS: We had a 59% (20/34 sites) response rate, with 10 sites having at least two participants. Respondents included neonatologists (53%) and neurosurgeons (35%). Most participants stated having a standard guideline for PHH (79%). Despite this, 42% of respondents perceive inconsistencies in management. Eight same-center pairs of neonatologists and neurosurgeons were used to determine response agreement. Half of these pairs disagreed on nearly all aspects of care. The greatest agreement pertained to a willingness to adopt a consensus-based protocol. CONCLUSION: Practice variation in the management of infants at risk of PHH in level IV NICUs exists despite the perception that a common practice is available and used. KEY POINTS: · Practice variation exists despite the perception that common practices are available/used for PHH.. · Our survey had same-center pairs of neonatologist and neurosurgeons to determine response agreement.. · The greatest agreement pertained to a willingness to adopt a consensus-based protocol..

HOPE and DREAM: A Two-Clinic NICU Follow-up Model.

OBJECTIVE: The natural extension of inpatient-focused neonatal neurocritical care (NNCC) programs is the evaluation of long-term neurodevelopmental outcomes in the same patient population. CLINICAL DESIGN: A dedicated and collaborative team of neonatologists, neonatal neurologists, neuropsychologists, neurosurgeons, physical medicine and rehabilitation physicians, and psychologists are necessary to provide personalized medicine, developmental assessments, and parental education for NNCC graduates. To achieve this goal, we devised a two-clinic follow-up model at Children's Wisconsin: HOPE (Healthy Outcomes Post-ICU Engagement) and DREAM: Developmentally Ready: Engagement for Achievement of Milestones) clinics. Those infants with significant neurologic diagnoses attend DREAM clinic, while all other high-risk neonatal intensive care unit (NICU) infants are seen in the HOPE clinic. CONCLUSION: These clinic models allow for a targeted approach to post-NICU care, which has improved family engagement and perceptions of value. KEY POINTS: · Infants with neurologic compromise are a specialized population with increasing survival.. · Interdisciplinary NICU follow-up brings together previously separated outpatient service lines.. · Our novel clinic model allows for specialized developmental assessments..

Word type and modality in the emerging expressive vocabularies of preschool children with Down syndrome.

BACKGROUND: Previous studies have explored the size and word type composition (nouns, predicates, etc.) of expressive vocabularies of preschool children with Down syndrome, both spoken and signed. Separately, overall preferences for modality of expression have also been explored. AIMS: To extend previous findings by describing the relationships between expressive vocabulary size and both word type and modality of expression in the preschool period including changes to modality preference over time. METHODS & PROCEDURES: Mothers of 35 children with Down syndrome, aged 36-66 months and attending the same early intervention programme, completed a version - with both spoken word and sign options - of the New Zealand MacArthur-Bates Communicative Development Inventory (CDI): Words and Sentences. Most mothers completed the CDI on multiple occasions across the duration of the study. Completions (n = 114) were analysed cross-sectionally and longitudinally in terms of (1) word type relative to vocabulary size, (2) modality of expression relative to word type and vocabulary size, and (3) individual trajectories in vocabulary size and modality of expression. OUTCOMES & RESULTS: (1) Word type relative to vocabulary size was similar to previous studies with a greater proportion of the SOCIAL words being present in the children's vocabularies throughout, followed by NOUNS, PREDICATES and CLOSED class words, with proportions converging as vocabulary sizes increase. (2) An initial spoken word preference for SOCIAL and CLOSED class words and sign preference for NOUNS and PREDICATES was found, with more spoken words in larger vocabularies overall. (3) Individual trajectories were highly variable and also revealed temporary points of regression in overall expressive vocabulary size in some children. Children who shifted from reliance on sign to predominantly spoken word expression did so at different ages and at different vocabulary sizes. At school entry, while most of the children used both modalities, some children continued to rely on sign for most vocabulary items whereas others used only spoken words. CONCLUSIONS & IMPLICATIONS: An appreciation of both the general trends and potential for individual variation in vocabulary structure, modality of expression and change over time will better position clinicians and education specialists to provide individually tailored support to both preschool and school-aged children with Down syndrome. WHAT THIS STUDY ADDS: What is already known on this subject Preschool children with Down syndrome have been shown to demonstrate developmental patterns in overall conceptual vocabulary size and word type development broadly similar to typical development. The use of signed vocabulary has also been explored, but independently from word type development and with less attention to individual trajectories in either vocabulary size development or modality preferences throughout the preschool period than is necessary for clinical use. What this paper adds to existing knowledge This study found interactions between word type and modality of expression in relation to vocabulary size as well as a few temporary vocabulary size regressions similar to those found in much younger typically developing children. An initial spoken word preference for social and closed class words, and sign preference for nouns and predicates, was followed by a general trend towards spoken words for all word types as vocabulary (with some fluctuations) increased over time. Children demonstrated considerable individual variation in size of vocabulary and age at which they pivoted from a signed to a spoken word preference. Moreover, while most children used both modalities at school entry, a few retained a sign-only vocabulary and others had moved fully onto spoken word-only expression. What are the potential or actual clinical implications of this work? An understanding of both the general trends and individual variation in vocabulary structure and modality of expression development will better position clinicians and educational specialists to provide individually tailored support to children with Down syndrome.

Astrocytic responses to high glucose impair barrier formation in cerebral microvessel endothelial cells.

Hyperglycemic conditions are prodromal to blood-brain barrier (BBB) impairment. The BBB comprises cerebral microvessel endothelial cells (CMECs) that are surrounded by astrocytic foot processes. Astrocytes express high levels of gap junction connexin 43 (Cx43), which play an important role in autocrine and paracrine signaling interactions that mediate gliovascular cross talk through secreted products. One of the key factors of the astrocytic "secretome" is vascular endothelial growth factor (VEGF), a potent angiogenic factor that can disrupt BBB integrity. We hypothesize that high-glucose conditions change the astrocytic expression of Cx43 and increase VEGF secretion leading to impairment of CMEC barrier properties in vitro and in vivo. Using coculture of neonatal rat astrocytes and CMEC, we mimic hyperglycemic conditions using high-glucose (HG) feeding media and show a significant decrease in Cx43 expression and the corresponding increase in secreted VEGF. This result was confirmed by the analyses of Cx43 and VEGF protein levels in the brain cortex samples from the type 2 diabetic rat (T2DN). To further characterize inducible changes in BBB, we measured transendothelial cell electrical resistance (TEER) and tight junction protein levels in cocultured conditioned astrocytes with isolated rat CMEC. The coculture monolayer's integrity and permeability were significantly compromised by HG media exposure, which was indicated by decreased TEER without a change in tight junction protein levels in CMEC. Our study provides insight into gliovascular adaptations to increased glucose levels resulting in impaired cellular cross talk between astrocytes and CMEC, which could be one explanation for cerebral BBB disruption in diabetic conditions.

Roles for ClpXP in regulating the circadian clock in Synechococcus elongatus.

In cyanobacteria, the KaiABC posttranslational oscillator drives circadian rhythms of gene expression and controls the timing of cell division. The Kai-based oscillator can be reconstituted in vitro, demonstrating that the clock can run without protein synthesis and degradation; however, protein degradation is known to be important for clock function in vivo. Here, we report that strains deficient in the ClpXP1P2 protease have, in addition to known long-period circadian rhythms, an exaggerated ability to synchronize with the external environment (reduced "jetlag") compared with WT strains. Deletion of the ClpX chaperone, but not the protease subunits ClpP1 or ClpP2, results in cell division defects in a manner that is dependent on the expression of a dusk-peaking factor. We propose that chaperone activities of ClpX are required to coordinate clock control of cell division whereas the protease activities of the ClpXP1P2 complex are required to maintain appropriate periodicity of the clock and its synchronization with the external environment.

Phototaxis in a wild isolate of the cyanobacterium Synechococcus elongatus.

Many cyanobacteria, which use light as an energy source via photosynthesis, have evolved the ability to guide their movement toward or away from a light source. This process, termed "phototaxis," enables organisms to localize in optimal light environments for improved growth and fitness. Mechanisms of phototaxis have been studied in the coccoid cyanobacterium Synechocystis sp. strain PCC 6803, but the rod-shaped Synechococcus elongatus PCC 7942, studied for circadian rhythms and metabolic engineering, has no phototactic motility. In this study we report a recent environmental isolate of S. elongatus, the strain UTEX 3055, whose genome is 98.5% identical to that of PCC 7942 but which is motile and phototactic. A six-gene operon encoding chemotaxis-like proteins was confirmed to be involved in phototaxis. Environmental light signals are perceived by a cyanobacteriochrome, PixJSe (Synpcc7942_0858), which carries five GAF domains that are responsive to blue/green light and resemble those of PixJ from Synechocystis Plate-based phototaxis assays indicate that UTEX 3055 uses PixJSe to sense blue and green light. Mutation of conserved functional cysteine residues in different GAF domains indicates that PixJSe controls both positive and negative phototaxis, in contrast to the multiple proteins that are employed for implementing bidirectional phototaxis in Synechocystis.

Quality improvement for reducing utilization drift in hypoxic-ischemic encephalopathy management.

OBJECTIVES: Therapeutic hypothermia is an effective neuroprotective intervention for infants with moderate or severe hypoxic-ischemic encephalopathy (HIE). With the introduction of new medical therapy comes a learning curve with regards to its proper implementation and understanding of eligibility guidelines. We hypothesized that variation in patient selection and lack of adherence to established protocols contributed to the utilization drift away from the original eligibility guidelines. METHODS: A retrospective cohort study was conducted including infants who received therapeutic hypothermia in the neonatal intensive care unit (NICU) for HIE to determine utilization drift. We then used QI methodology to address gaps in medical documentation that may lead to the conclusion that therapeutic hypothermia was inappropriately applied. RESULTS: We identified 54% of infants who received therapeutic hypothermia who did not meet the clinical, physiologic, and neurologic examination criteria for this intervention based on provider admission and discharge documentation within the electronic medical record (EMR). Review of the charts identified incomplete documentation in 71% of cases and led to the following interventions: 1) implementation of EMR smartphrases; 2) engagement of key stakeholders and education of faculty, residents, and neonatal nurse practitioners; and 3) performance measurement and sharing of data. We were able to improve both adherence to the therapeutic hypothermia guidelines and achieve 100% documentation of the modified Sarnat score. CONCLUSIONS: Incomplete documentation can lead to the assumption that therapeutic hypothermia was inappropriately applied when reviewing a patient's EMR. However, in actual clinical practice physicians follow the clinical guidelines but are not documenting their medical decision making completely. QI methodology addresses this gap in documentation, which will help determine the true utilization drift of therapeutic hypothermia in future studies.

Ecosystem-based management for military training, biodiversity, carbon storage and climate resiliency on a complex coastal land/water-scape.

The Defense Coastal/Estuarine Research Program (DCERP) was a 10-year multi-investigator project funded by the Department of Defense to improve understanding of ecosystem processes and their interactions with natural and anthropogenic stressors at the Marine Corps Base Camp Lejeune (MCBCL) located in coastal North Carolina. The project was aimed at facilitating ecosystem-based management (EBM) at the MCBCL and other coastal military installations. Because of its scope, interdisciplinary character, and duration, DCERP embodied many of the opportunities and challenges associated with EBM, including the need for explicit goals, system models, long-term perspectives, systems complexity, change inevitability, consideration of humans as ecosystem components, and program adaptability and accountability. We describe key elements of this program, its contributions to coastal EBM, and its relevance as an exemplar of EBM.

The roles of language use and vocabulary size in the emergence of word-combining in children with complex neurodevelopmental disabilities.

Parent report data on 82 preschool children with complex neurodevelopmental disabilities including Down syndrome, dyspraxia, autism, and global developmental delay suggests communicative language use must reach a threshold level before vocabulary size becomes the best predictor of word combining. Using the Language Use Inventory and the MacArthur-Bates CDI (with sign vocabulary option), statistical modelling using regression trees and random forests suggests that, despite high linear correlations between variables, (1) pragmatic ability, particularly children's emerging ability to talk about things, themselves and others is a significantly better predictor of the earliest word combining than vocabulary size; and (2) vocabulary size becomes a better predictor of later word combining, once this pragmatic base has been established.

Risk Factors Linked to Central Catheter-Associated Thrombosis in Critically Ill Infants in the Neonatal Intensive Care Unit.

OBJECTIVE: Our study identified risk factors for the development of clinically identifiable catheter-associated thrombosis (CT). STUDY DESIGN: We performed a retrospective cohort study of neonates in whom a central catheter was present. A total of 1,475 catheters were identified in 766 patients during a 36-month study period. The odds ratio (OR) of thrombi formation in catheterized neonates was modeled using simple (single predictor) and multiple (multiple predictors) logistic regressions as well as simple and multiple Cox's proportional hazard models. RESULT: The incidence of CT was 1.17 per 100 neonates. Unadjusted factors including age at insertion, history of surgery before or during line placement, cholestasis, femoral location, and line size significantly increased the OR or hazards ratio (HR) of developing thrombi formation. In multiple logistic and Cox's regression analyses, three factors continued to be significantly associated with OR or HR of thrombi formation: line size, femoral location, and cholestasis. CONCLUSION: We conclude that clinically identifiable CT is rare in the neonatal population. Furthermore, catheter-specific characteristics are predictive for CT and require further investigation.

Adverse early life environment induces anxiety-like behavior and increases expression of FKBP5 mRNA splice variants in mouse brain.

Adverse early life environment (AELE) predisposes adult offspring toward anxiety disorders. Anxiety disorders are associated with prenatal injuries in key regions of the brain including prefrontal cortex (PFC), hippocampus (HP), and hypothalamus (HT). Injuries in these brain regions result in an impaired hypothalamus-pituitary-adrenal axis (HPA axis) and stress response. An important regulator of the stress response is FK506-binding protein 5 (FKBP5). FKBP5 is a cochaperone of the glucocorticoid receptor (GR) and inhibits GR-mediated regulatory feed-back on the HPA axis in response to stress. Human studies have shown that polymorphisms of FKBP5 are associated with higher FKBP5 levels. Increased FKBP5 leads to GR resistance and impaired negative feedback, which is associated with anxiety disorders. FKBP5 and its mRNA splice variants in the aforementioned brain regions have not been reported. We hypothesized that AELE will increase expression of FKBP5 and its mRNA splice variants in PFC, HP, and HT as well as increase anxiety in adult mice. AELE increased expression of FKBP5 and its mRNA variants in PFC, HP and HT at postnatal day 21. Additionally, AELE caused anxiety and increased GR abundance in association with these changes in FKBP5 expression. We speculate that these changes in FKBP5 mRNA variants affect HPA axis function and contributes to subsequent anxiety-like behavior later in life in AELE mice.

The Female Self-Advocacy in Cancer Survivorship Scale: A validation study.

AIM: To develop and psychometrically test the validity of the Female Self-Advocacy in Cancer Survivorship Scale. BACKGROUND: Female cancer survivors need to self-advocate to overcome challenges associated with cancer yet no valid measure of self-advocacy exists. DESIGN: Instrument development. Mixed-mode cross-sectional survey design. PARTICIPANTS: We recruited adult females (18+ years; N = 317) with a history of invasive cancer from local and national tumour registries and advocacy organizations to complete online or paper questionnaires. METHODS: Between July 2014 - March 2015 to evaluate the construct validity based on evidence of the scale's: (1) internal structure consistent with the underlying model of self-advocacy; (2) sensitivity to differences between groups known to differ in self-advocacy skills; (3) relationships between self-advocacy and key potential predictors (openness and conscientiousness; information engagement; social support) and outcomes (symptom burden and healthcare utilization); (4) relationships between self-advocacy and related concepts (patient activation; self-advocacy within another patient population); and (5) relationships between self-advocacy and criterion measures. Analyses included an exploratory factor analysis, t tests, and bivariate correlations using validated, reliable measures for constructs. RESULTS: Evidence from all five hypotheses supported the construct validity of the Female Self-Advocacy in Cancer Survivorship Scale. The factor analysis confirmed the three underlying dimensions of self-advocacy resulting in a 20-item measure with strong internal consistency that explained almost half of response variance. CONCLUSION: The Female Self-Advocacy in Cancer Survivorship Scale is a valid, reliable measure of how well adult female cancer survivors can get their needs met in the face of adversity.

Examining the relationship between multiple primary cancers and psychological distress: A review of current literature.

OBJECTIVE: The incidence of multiple primary cancers (MPCs) is increasing, but little is known about psychological distress in this population. The purpose of this study is to review and synthesize the literature regarding what is known about psychological distress in adults who have experienced MPC diagnoses. METHODS: All potentially eligible studies identified in PubMed and CINAHL were reviewed by 2 independent evaluators, and each relevant article was assessed for methodological quality. Data were extracted, organized, and recorded using a coding log, PRISMA flow diagram, and a standardized table of evidence. Effect size (ES) values were calculated using Cohen's d. RESULTS: Five of the 562 potentially relevant articles were selected for final analysis. MPC survivors, when compared with single cancer survivors, had lower global quality of life (d = 0.32-0.37), poorer emotional role function and stress (d = 0.08-0.20), greater and more frequent distress (d = 0.11-0.37), and greater subclinical anxiety (d = 0.15). Depressive symptoms were variable (d = 0.01-0.22), and no differences between MPC and single cancer groups were identified for sleep and suicidal ideation. CONCLUSION: There is a substantial lack of evidence focused on psychological distress among the growing MPC survivor population. ES noted in the 5 studies reflect small but potentially significant increases in psychological distress in survivors of MPC compared with survivors of a single cancer. Clinicians should be aware of this at-risk population when screening for distress in cancer survivors. Suggestions for future research are provided.
