Who do you ask? predicting injury rates from survey responses.

BACKGROUND: Few studies have addressed whether using manager or worker perceptions of safety policies and practices alone predict reported injury rates less accurately than using both. OBJECTIVE: This study provides an example and describes a method that can be used to address this issue with survey instruments designed to measure safety climate, policies, or practices. METHODS: Using multilevel logistic regression, we estimated the relationship between worker and manager perceptions of a given exposure and the odds of worker injury during the post-survey year for three safety scales. We tested whether surveying both workers and managers provides additional predictive value compared with surveying just one group. RESULTS: Injury in the year following the survey was significantly associated with worker scores on two of the three scales. Manager responses were not significantly associated with injury and did not significantly improve injury rate prediction when added to a model with only worker survey responses. CONCLUSIONS: The capacity of manager-only or worker-only perceptions of safety policies and practices to predict worker injuries should be established before choosing to survey just one or the other. The approach and findings in this paper can be applied to other survey instruments and in other settings to help make this choice.

Pregnancy-specific dietary guidelines for Americans are not met: Findings from a pilot study.

Objective: To assess maternal dietary intake during pregnancy and adherence to the 2020-2025 pregnancy-specific Dietary Guidelines for Americans (DGA). Methods: This was a retrospective observational study. The study population consisted of women who gave birth to term infants (>37 weeks of gestation). Participants were given the Dietary Screener Questionnaire (DSQ) after birth and asked to recall their dietary intake in the last month of pregnancy. Participants' estimated dietary intakes were then compared to the 2020-2025 DGA which includes specific recommendations for pregnant women. Results: Out of 51 women who completed the DSQ, none consumed the recommended amounts of all surveyed dietary factors. Specifically, only one woman (2%) met the recommended intake of fruits, 11 women (22%) met the recommended intake of calcium, 25 women (49%) exceeded the recommended upper limit for added sugar intake, and none of the women (0%) met the intake of vegetables, whole grains, dairy and fiber. Conclusion: Women in our study did not adhere to the pregnancy-specific DGA recommendations in the last month of pregnancy. Our findings underscore the need to increase maternal nutritional awareness and education to improve adherence to the DGA.

Human milk pH is associated with fortification, postpartum day, and maternal dietary intake in preterm mother-infant dyads.

OBJECTIVE: To compare pH of human milk types (mother's own milk (MOM), pasteurized donor human milk (PDHM), fortified MOM, and fortified PDHM) fed to preterm infants. STUDY DESIGN: This observational study consisted of 63 mother-infant dyads < 34 weeks gestation. Human milk samples (n = 245), along with maternal factors, were collected for pH analysis. pH of MOM was analyzed over the course of lactation accounting for fortification status, postpartum day, and storage conditions. RESULTS: Mean pH of MOM was slightly acidic at 6.60 ± 0.28, which was significantly higher (p < 0.05) than other milk types. pH of MOM varied by fortification, postpartum day, and maternal vegetable/fiber intake. There was a significant interaction between fortification status and postpartum day; pH of MOM decreased over time, while pH of fortified MOM increased over time. CONCLUSION: pH of human milk varied by type. pH of MOM was significantly associated with fortification status, postpartum day, and maternal vegetable/fiber intake.

Factors associated with refeeding hypophosphatemia in adolescents and young adults hospitalized with anorexia nervosa.

BACKGROUND: Refeeding hypophosphatemia (RH) in individuals with anorexia nervosa (AN) is a potentially fatal complication of nutrition restoration; yet, little is known about risk. This retrospective cohort study examined factors found in hospitalized youth with AN that may contribute to RH. METHODS: We reviewed medical records of 300 individuals diagnosed with AN admitted between the years of 2010 and 2016. Logistic regression examined factors associated with RH. Multivariate regression examined factors associated with phosphorus nadir. RESULTS: For 300 participants, the mean (SD) age was 15.5 (2.5) years, 88.3% were White, and 88.3% were female. Participants lost an average of 11.3 (9.7) kg of body weight and were 82% (12.1) of median body mass index (BMI). Age (P = .022), nasogastric (NG) tube feeding (P = .054), weight gain (P = .003), potassium level (P = .001), and magnesium level (P = .024) were contributors to RH. Odds of RH were 13.7 times higher for each unit reduction in magnesium, 9.2 times higher for each unit reduction in potassium, three times higher in those who received NG feeding, 1.5 times higher for each kg of weight gain, and 1.2 times higher for each year of age. Regarding phosphorus nadir, serum magnesium level (P < .001) and admission BMI (P = .002) contributed significantly. CONCLUSION: The results indicate that age, NG feeding, weight gain, electrolyte abnormalities, and BMI on admission are potential indicators of the development of RH in youth. This study identifies clinical risk factors associated with RH and may guide further investigation.

Predictors of Caregiver Burden in Delirium: Patient and Caregiver Factors.

The current study examined the association of patient factors, patient/caregiver relationships, and living arrangements with caregiver burden due to delirium. The sample included a subset (N = 207) of hospitalized medical and surgical patients (aged >70 years) enrolled in the Better Assessment of Illness Study and their care-givers. The majority of caregivers were female (57%) and married (43%), and 47% reported living with the patient. Delirium occurred in 22% of the sample, and delirium severity, pre-existing cognitive impairment, and impairment of any activities of daily living (ADL) were associated with higher caregiver burden. However, only the ADL impairment of needing assistance with transfers was independently significantly associated with higher burden (p < 0.01). Child, child-in-law, and other relatives living with or apart from the patient reported significantly higher caregiver burden compared to spouse/partners (p < 0.01), indicating caregiver relationship and living arrangement are associated with burden. Future studies should examine additional factors contributing to delirium burden. [Journal of Gerontological Nursing, 47(9), 32-39.].

Framing Effects on Decision-Making for Diagnostic Genetic Testing: Results from a Randomized Trial.

Genetic testing is increasingly part of routine clinical care. However, testing decisions may be characterized by regret as findings also implicate blood relatives. It is not known if genetic testing decisions are affected by the way information is presented (i.e., framing effects). We employed a randomized factorial design to examine framing effects on hypothetical genetic testing scenarios (common, life-threatening disease and rare, life-altering disease). Participants (n = 1012) received one of six decision frames: choice, default (n = 2; opt-in, opt-out), or enhanced choice (n = 3, based on the Theory of Planned Behavior). We compared testing decision, satisfaction, regret, and decision cognitions across decision frames and between scenarios. Participants randomized to 'choice' were least likely to opt for genetic testing compared with default and enhanced choice frames (78% vs. 83-91%, p < 0.05). Neither satisfaction nor regret differed across frames. Perceived autonomy (behavioral control) predicted satisfaction (B = 0.085, p < 0.001) while lack of control predicted regret (B = 0.346, p < 0.001). Opting for genetic testing did not differ between disease scenarios (p = 0.23). Results suggest framing can nudge individuals towards opting for genetic testing. These findings have important implications for individual self-determination in the genomic era. Similarities between scenarios with disparate disease trajectories point to possible modular approaches for web-based decisional support.

Actual Use of Multiple Health Monitors Among Older Adults With Diabetes: Pilot Study.

BACKGROUND: Previous studies have reported older adults' perceptions of using health monitors; however, no studies have examined the actual use of multiple health monitors for lifestyle changes over time among older adults with type 2 diabetes (T2D). OBJECTIVE: The primary aim of this study was to examine the actual use of multiple health monitors for lifestyle changes over 3 months among older adults with T2D. The secondary aim was to explore changes in caloric intake and physical activity (PA) over 3 months. METHODS: This was a single-group study lasting 3 months. The study sample included participants who were aged ≥65 years with a diagnosis of T2D. Participants were recruited through fliers posted at the Joslin Diabetes Center in Boston. Participants attended five 60-min, biweekly group sessions, which focused on self-monitoring, goal setting, self-regulation to achieve healthy eating and PA habits, and the development of problem-solving skills. Participants were provided with the Lose It! app to record daily food intake and devices such as a Fitbit Alta for monitoring PA, a Bluetooth-enabled blood glucose meter, and a Bluetooth-enabled digital scale. Descriptive statistics were used for analysis. RESULTS: Of the enrolled participants (N=9), the sample was white (8/9, 89%) and female (4/9, 44%), with a mean age of 76.4 years (SD 6.0; range 69-89 years), 15.7 years (SD 2.0) of education, 33.3 kg/m2 (SD 3.1) BMI, and 7.4% (SD 0.8) hemoglobin A1c. Over the 84 days of self-monitoring, the mean percentage of days using the Lose It!, Fitbit Alta, blood glucose meter, and scale were 82.7 (SD 17.6), 85.2 (SD 19.7), 65.3 (SD 30.1), and 53.0 (SD 34.5), respectively. From baseline to completion of the study, the mean daily calorie intake was 1459 (SD 661) at week 1, 1245 (SD 554) at week 11, and 1333 (SD 546) at week 12, whereas the mean daily step counts were 5618 (SD 3654) at week 1, 5792 (SD 3814) at week 11, and 4552 (SD 3616) at week 12. The mean percentage of weight loss from baseline was 4.92% (SD 0.25). The dose of oral hypoglycemic agents or insulin was reduced in 55.6% (5/9) of the participants. CONCLUSIONS: The results from the pilot study are encouraging and suggest the need for a larger study to confirm the outcomes. In addition, a study design that includes a control group with educational sessions but without the integration of technology would offer additional insight to understand the value of mobile health in behavior changes and the health outcomes observed during this pilot study.

Nutrition-Related Clinical Decision Making of Pediatric Oncology Nurses.

Children with a cancer diagnosis have risk factors leading to unique nutritional challenges. Malnutrition in this population is correlated with worse patient outcomes. Nurses are responsible for providing holistic care to their patients; however, the quality of nutritional assessments by pediatric oncology nurses is unknown. The purpose of this study was to investigate staff nurses' clinical decision making regarding nutritional assessment of children with cancer. A web-based survey composed of a demographic form, vignettes of patients with diverse nutritional status and the New General Self-Efficacy Scale, was distributed to members of the Association of Pediatric Hematology Oncology Nurses. Participants were also asked to rate their confidence in responses as well as select key nutritional cues. Nurses were significantly more likely to under-rate the nutritional status and select far fewer cues than the experts. Further research regarding nutritional assessment is warranted. Evidenced-based guidelines for nutritional assessment of children with cancer should be developed to ensure the highest quality of care is provided to this patient population.

Child Sexual Abuse and Depression in Late Life for Men: A Population-Based, Longitudinal Analysis.

OBJECTIVE: Research investigating long-term effects of childhood sexual abuse (CSA) on mental health for men is vastly underdeveloped. This study strengthened the knowledge base by examining: (a) long-term trajectories of depressive symptoms for men with and without a history of CSA, and (b) moderating effects of social support over time. METHOD: We analyzed multiple waves of data from the Wisconsin Longitudinal Study. The sample (N = 2,451) consisted of men with histories of CSA and a stratified, randomly sampled comparison group. Growth curve modeling was employed for analyses. RESULTS: After controlling for demographic, parental, and health factors, men with CSA histories had greater depressive symptoms than those with no history of CSA. For both groups, depressive symptoms decreased over time; slope patterns did not differ. We found a significant moderating effect of social support on the relationship between CSA and depressive symptoms. DISCUSSION: This innovative, population-based, longitudinal study demonstrated that CSA can undermine mental health for men across the life span and into old age. Social support appears to mitigate these deleterious effects. In early, middle, and late adulthood, practitioners should assess for CSA and strengthen support resources for male survivors.

Symptoms of Feeding Problems in Preterm-born Children at 6 Months to 7 Years Old.

OBJECTIVES: Describe symptoms of feeding problems in children born very preterm (<32 weeks gestation) and moderate to late preterm (32-37 weeks gestation) compared to children born full-term; explore the contribution of medical risk factors to problematic feeding symptoms. METHODS: The sample included 57 very preterm, 199 moderate to late preterm, and 979 full-term born children ages 6 months to 7 years. Symptoms of feeding problems were assessed using the Pediatric Eating Assessment Tool and compared between groups after accounting for the child's age and/or sex. With the sample of preterm children, we further analyzed 11 medical factors as potential risk factors affecting a child's feeding symptoms: feeding problems in early infancy and conditions of oxygen requirement past 40 weeks of postmenstrual age, congenital heart disease, structural anomaly, genetic disorder, cerebral palsy, developmental delay, speech-language delay, sensory processing disorder, vision impairment, or symptoms of gastroesophageal reflux. RESULTS: Compared to children born full-term, both very preterm and moderate to late preterm born children had significantly higher scores on the Pediatric Eating Assessment Tool total scale and all 4 subscales. More severe symptoms were noted in very preterm children, particularly in the areas of Physiologic Symptoms and Selective/Restrictive Eating. Among preterm children, all 11 medical factors were found to be associated significantly with increased symptoms of feeding problems. CONCLUSION: Compared to children born full-term, preterm born children demonstrated greater symptoms of feeding problems regardless of their current age, suggesting children born preterm may require more careful monitoring of feeding throughout childhood.

Development of the Leadership Influence Self-Assessment (LISA©) instrument.

PURPOSE: This study aims to describe the development and psychometric evaluation of the Leadership Influence Self-Assessment (LISA©) tool. BACKGROUND: LISA© was designed to help nurse leaders assess and enhance their influence capacity by measuring influence traits and practices and identifying areas of strength and weakness. METHODS: Concepts identified in the Adams Influence Model and input from content experts guided the development of 145 items for testing. Administered to 165 nurse leaders, the assessment was subjected to exploratory factor analysis (EFA). FINDINGS: EFA yielded a four-factor solution that comprised 80 items. Cronbach's alpha for factors ranged between 0.912 and 0.938. All factor loadings were >0.4; the smallest factor contained 14 items. Items grouped together in the theoretical model also clustered together in the EFA. CONCLUSIONS: Preliminary psychometric testing supports validity and reliability of the LISA© and its potential use as a tool to assess influence capacity for purposes of leadership development and research.

Predictors of 30-Day Readmission for Pneumonia.

OBJECTIVE: This study examined data from 4 sources: number of hospital-acquired conditions, patient perception of care, quality outcome measures, and demographic data to explain variances associated with 30-day pneumonia readmission rates. BACKGROUND: Patients readmitted within 30 days for pneumonia increases the length of hospital stay by 7 to 9 days, increases crude mortality rate 30% to 70%, and costs of $40,000 or greater per patient. METHODS: Variances in outcomes measures associated with 30-day pneumonia readmissions from 577 nonfederal general hospitals in Massachusetts, California, and New York were analyzed using datasets from Hospital Consumer Assessment of Healthcare Providers and Systems, Centers of Medicare & Medicaid Services, Agency for Healthcare Research and Quality, and American Hospital Association. RESULTS: Three factors increased pneumonia readmission rates: poor nurse-patient communication, poor staff responsiveness to patient needs, and iatrogenic pneumothorax. Conversely, factors lowering pneumonia readmission rates included patients hospitalized in California, higher RN staffing, and higher proportions of nursing staff to total hospital personnel. CONCLUSION: Findings suggest lower nurse staffing, poor nurse-patient communication, and nurse responsiveness to patient needs contribute to increased pneumonia readmission rates.

Mode of Birth Influences Preterm Infant Intestinal Colonization With Bacteroides Over the Early Neonatal Period.

BACKGROUND: Intestinal colonization during infancy is important to short- and long-term health outcomes. Bacteroides, an early member of the intestinal microbiome, is necessary for breaking down complex molecules within the intestine and function to assist the body's immune system in fighting against potentially harmful pathogens. Little is known about the colonization pattern of Bacteroides in preterm infants during the early neonatal period. PURPOSE: This study measured Bacteroides colonization during the early neonatal period in a population of preterm infants, based on clinical factors including mode of birth, antibiotics, and nutrition. METHODS: Bacterial DNA was isolated from 144 fecal samples from 29 preterm infants and analyzed using quantitative real-time polymerase chain reaction. Analyses included liner mixed models to determine which clinical factors affect Bacteroides colonization of the infant gut. RESULTS: We found that infants born via vaginal canal had a higher rate of increase in Bacteroides than infants born via cesarean section (P < .001). We did not find significant associations between antibiotic administration and differences in nutritional exposures with Bacteroides colonization. IMPLICATIONS FOR PRACTICE: These findings highlight the significant influence of mode of birth on Bacteroides colonization. While mode of birth is not always modifiable, these study findings may help develop interventions for preterm infants born via cesarean section aimed at overcoming delayed Bacteroides colonization. IMPLICATIONS FOR RESEARCH: Greater study of the intestinal microbiome and the clinical factors relevant to the preterm infant is needed so that interventions may be developed and tested, resulting in optimal microbial and immune health.

Napping in college students and its relationship with nighttime sleep.

UNLABELLED: Abstract. OBJECTIVE: To examine the habit of napping and its relationship with nighttime sleep in college students. PARTICIPANTS: Four hundred and forty undergraduate students who responded to an anonymous online survey in April 2010. METHODS: Three questions were asked to determine the frequency, length, and timing of napping during the past month. Sleep quality was measured by the Pittsburgh Sleep Quality Index (PSQI). RESULTS: The PSQI score significantly differed among self-reported nap-frequency (p=.047) and nap-length (p=.017) groups, with those who napped more than 3 times per week and those who napped more than 2 hours having the poorest sleep quality. Students who napped between 6 and 9 pm had shorter sleep on school nights compared with students in other nap-timing groups (p=.002). CONCLUSIONS: College students who are self-reported frequent, long, and late nappers may have a higher risk of poor nighttime sleep quality and more severe sleep deprivation.

Safety, pharmacokinetics, and preliminary assessment of efficacy of mecasermin (recombinant human IGF-1) for the treatment of Rett syndrome.

Rett syndrome (RTT) is a severe X-linked neurodevelopmental disorder mainly affecting females and is associated with mutations in MECP2, the gene encoding methyl CpG-binding protein 2. Mouse models suggest that recombinant human insulin-like growth factor 1 (IGF-1) (rhIGF1) (mecasermin) may improve many clinical features. We evaluated the safety, tolerability, and pharmacokinetic profiles of IGF-1 in 12 girls with MECP2 mutations (9 with RTT). In addition, we performed a preliminary assessment of efficacy using automated cardiorespiratory measures, EEG, a set of RTT-oriented clinical assessments, and two standardized behavioral questionnaires. This phase 1 trial included a 4-wk multiple ascending dose (MAD) (40-120 µg/kg twice daily) period and a 20-wk open-label extension (OLE) at the maximum dose. Twelve subjects completed the MAD and 10 the entire study, without evidence of hypoglycemia or serious adverse events. Mecasermin reached the CNS compartment as evidenced by the increase in cerebrospinal fluid IGF-1 levels at the end of the MAD. The drug followed nonlinear kinetics, with greater distribution in the peripheral compartment. Cardiorespiratory measures showed that apnea improved during the OLE. Some neurobehavioral parameters, specifically measures of anxiety and mood also improved during the OLE. These improvements in mood and anxiety scores were supported by reversal of right frontal alpha band asymmetry on EEG, an index of anxiety and depression. Our data indicate that IGF-1 is safe and well tolerated in girls with RTT and, as demonstrated in preclinical studies, ameliorates certain breathing and behavioral abnormalities.

Predictors of excess heart failure readmissions: implications for nursing practice.

In this study of California, Massachusetts, and New York hospitals, 6 factors predicted 27.6% of readmissions for patients with heart failure (HF). We found that higher admissions per bed, teaching hospitals, and poor nurse-patient communication increased HF readmissions. Conversely, the HF readmissions were lower when nurse staffing was greater, more patients reported receiving discharge information, and among hospitals in California. The implications for nursing practice in the delivery of care to patients with HF are discussed.

Cardiopulmonary complications during pediatric seizures: a prelude to understanding SUDEP.

PURPOSE: Sudden unexpected death in epilepsy (SUDEP) is an important, unexplained cause of death in epilepsy. Role of cardiopulmonary abnormalities in the pathophysiology of SUDEP is unclear in the pediatric population. Our objective was to assess cardiopulmonary abnormalities during epileptic seizures in children, with the long-term goal of identifying potential mechanisms of SUDEP. METHODS: We prospectively recorded cardiopulmonary functions using pulse-oximetry, electrocardiography (ECG), and respiratory inductance plethysmography (RIP). Logistic regression was used to evaluate association of cardiorespiratory findings with seizure characteristics and demographics. KEY FINDINGS: We recorded 101 seizures in 26 children (average age 3.9 years). RIP provided analyzable data in 78% and pulse-oximetry in 63% seizures. Ictal central apnea was more prevalent in patients with younger age (p = 0.01), temporal lobe (p < 0.001), left-sided (p < 0.01), symptomatic generalized (p = 0.01), longer duration seizures (p < 0.0002), desaturation (p < 0.0001), ictal bradycardia (p < 0.05), and more antiepileptic drugs (AEDs; p < 0.01), and was less prevalent in frontal lobe seizures (p < 0.01). Ictal bradypnea was more prevalent in left-sided (p < 0.05), symptomatic generalized seizures (p < 0.01), and in brain magnetic resonance imaging (MRI) lesions (p < 0.1). Ictal tachypnea was more prevalent in older-age (p = 0.01), female gender (p = 0.05), frontal lobe (p < 0.05), right-sided seizures (p < 0.001), fewer AEDs (p < 0.01), and less prevalent in lesional (p < 0.05) and symptomatic generalized seizures (p < 0.05). Ictal bradycardia was more prevalent in male patients (p < 0.05) longer duration seizures (p < 0.05), desaturation (p = 0.001), and more AEDs (p < 0.05), and was less prevalent in frontal lobe seizures (p = 0.01). Ictal and postictal bradycardia were directly associated (p < 0.05). Desaturation was more prevalent in longer-duration seizures (p < 0.0001), ictal apnea (p < 0.0001), ictal bradycardia (p = 0.001), and more AEDs (p = 0.001). SIGNIFICANCE: Potentially life-threatening cardiopulmonary abnormalities such as bradycardia, apnea, and hypoxemia in pediatric epileptic seizures are associated with predictable patient and seizure characteristics, including seizure subtype and duration.

Clinical correlates of Charcot-Marie-Tooth disease in patients with pes cavus deformities.

INTRODUCTION: Given its association with Charcot-Marie-Tooth disease (CMT), pes cavus is a common reason for referral to a neurologist. We investigated clinical features that may predict CMT in children with pes cavus. METHODS: In this study we retrospectively reviewed pes cavus patients referred to Boston Children's Hospital in the past 20 years. Patients were categorized as idiopathic or CMT, based on EMG/genetic testing, and their clinical features were compared. RESULTS: Of the 70 patients studied, 33 had idiopathic pes cavus, and 37 had genetically confirmed CMT. Symptoms of weakness, unsteady gait, family history of pes cavus and CMT, and signs of sensory deficits, distal atrophy and weakness, absent ankle jerks, and gait abnormalities were associated with CMT. CONCLUSIONS: In children with pes cavus, certain clinical features can predict CMT and assist in selection of patients for further, potentially uncomfortable (EMG) and expensive (genetic) confirmatory investigations.

Regional infant brain development: an MRI-based morphometric analysis in 3 to 13 month olds.

Elucidation of infant brain development is a critically important goal given the enduring impact of these early processes on various domains including later cognition and language. Although infants' whole-brain growth rates have long been available, regional growth rates have not been reported systematically. Accordingly, relatively less is known about the dynamics and organization of typically developing infant brains. Here we report global and regional volumetric growth of cerebrum, cerebellum, and brainstem with gender dimorphism, in 33 cross-sectional scans, over 3 to 13 months, using T1-weighted 3-dimensional spoiled gradient echo images and detailed semi-automated brain segmentation. Except for the midbrain and lateral ventricles, all absolute volumes of brain regions showed significant growth, with 6 different patterns of volumetric change. When normalized to the whole brain, the regional increase was characterized by 5 differential patterns. The putamen, cerebellar hemispheres, and total cerebellum were the only regions that showed positive growth in the normalized brain. Our results show region-specific patterns of volumetric change and contribute to the systematic understanding of infant brain development. This study greatly expands our knowledge of normal development and in future may provide a basis for identifying early deviation above and beyond normative variation that might signal higher risk for neurological disorders.
