Adverse Events Related to Accidental Unintentional Ingestions From Cough and Cold Medications in Children.

OBJECTIVES: Previous research has demonstrated that accidental unsupervised ingestions (AUIs) were responsible for the majority of cough and cold medication (CCM) ingestions leading to significant adverse events (AEs) in children. The objective of this analysis was to characterize the role of AUIs in the morbidity associated with CCM exposure in children. METHODS: This surveillance study collected data from 5 United States data sources from 2009 to 2016, in children younger than 6 years with an AE from an AUI involving at least 1 CCM over-the-counter pharmaceutical ingredient. An expert panel reviewed each case to determine causality. RESULTS: From 4756 total cases reviewed, 3134 (65.9%) had an AE from an AUI determined to be at least potentially related to a CCM ingredient. The majority (61.3%) of cases occurred in children aged 2 to younger than 4 years. Most exposures occurred in the child's own residence (94.9%), and 43.8% were admitted to a health care facility (22.0% to a critical care unit). Dextromethorphan and diphenhydramine, when packaged alone or in combination products, contributed to 96.0% of AUIs. The most common specific products involved were single-ingredient pediatric liquid diphenhydramine (30.1%) and single-ingredient pediatric liquid dextromethorphan (21.4%). There were 3 deaths from solid diphenhydramine formulations. CONCLUSIONS: There continues to be opportunities for the implementation of interventions to prevent AUIs of CCM in children. Additional emphasis on engineering controls, such as flow restrictors for liquid formulations targeting diphenhydramine and dextromethorphan products, represent additional opportunities to further reduce AEs from AUIs of CCM.

Measuring Fidelity to Evidence-Based Practices: Psychometrics.

This special section presents the psychometric properties of fidelity scales used in a national mental health services project in Norway to improve the quality of care of people with psychoses. Across Norway, 39 clinical units in six health trusts participated. The project provided education, implementation support and fidelity assessments. The papers in the section address the psychometrics of fidelity measurement for the specific evidence-based practices: illness management and recovery, family psychoeducation, physical healthcare and antipsychotic medication management. Another paper analyzes the psychometrics of a scale measuring individualization and quality improvement that may be used in conjunction with fidelity scales for specific evidence-based practices. The first paper in the section presents the development and field of fidelity scales, and the two final papers with comments add some additional perspectives and discuss fidelity scales in a wider context. The psychometrics of the five scales were good to excellent. Fidelity assessment is a necessary and effective strategy for quality improvement.

The Family Psychoeducation Fidelity Scale: Psychometric Properties.

This study examined psychometric properties and feasibility of the Family Psychoeducation (FPE) Fidelity Scale. Fidelity assessors conducted reviews using the FPE fidelity scale four times over 18 months at five sites in Norway. After completing fidelity reviews, assessors rated feasibility of the fidelity review process. The FPE fidelity scale showed excellent interrater reliability (.99), interrater item agreement (88%), and internal consistency (mean = .84 across four time points). By the 18-month follow-up, all five sites increased fidelity and three reached adequate fidelity. Fidelity assessors rated feasibility as excellent. The FPE fidelity scale has good psychometric properties and is feasible for evaluating the implementation of FPE programs. Trial registration ClinicalTrials.gov Identifier: NCT03271242.

Measuring implementation: development of the implementation process assessment tool (IPAT).

BACKGROUND: Implementation science comprises a large set of theories suggesting interacting factors at different organisational levels. Development of literature syntheses and frameworks for implementation have contributed to comprehensive descriptions of implementation. However, corresponding instruments for measuring these comprehensive descriptions are currently lacking. The present study aimed to develop an instrument measuring care providers' perceptions of an implementation effort, and to explore the instrument's psychometric properties. METHODS: Based on existing implementation literature, a questionnaire was designed with items on individual and team factors and on stages of change in an implementation process. The instrument was tested in a Norwegian study on implementation of evidence based practices for psychosis. Item analysis, factor structure, and internal consistency at baseline were examined. RESULTS: The 27-item Implementation Process Assessment Tool (IPAT) revealed large variation between mean score of the items. The total scale scores were widely dispersed across respondents. Internal consistency for the total scale was high (Cronbach's alpha: .962), and all but one item contributed positively to the construct. The results indicated four underlying constructs: individual stages for behavioural change, individual activities and perceived support, collective readiness and support, and individual perceptions of the intervention. CONCLUSIONS: The IPAT appears to be a feasible instrument for investigating the implementation process from the perspective of those making the change. It can enable examination of the relative importance of factors thought to be essential for implementation outcomes. It may also provide ongoing feedback for leaders tailoring support for teams to improve implementation. However, further research is needed to detect the instrument's properties later in the implementation process and in different contexts. TRIAL REGISTRATION: ClinicalTrials.gov code NCT03271242 (retrospective registered September 5, 2017).

Microvascular reconstruction of pediatric lower extremity trauma using free tissue transfer.

While free tissue transfer has long been established as a reliable microsurgical technique in the adult population, its application in pediatric reconstruction is a relatively recent phenomenon. Despite initial concerns regarding minute vessel diameters, increased propensity for vasospasm, and limited tissue availability, pediatric free tissue transfer is now a widely used technique that has demonstrated an acceptable level of donor and recipient site morbidity in children. Five flaps commonly used in the reconstruction of lower extremity trauma are discussed in this paper: the latissimus dorsi, rectus abdominis, anterolateral thigh, gracilis, and the subscapular and parascapular flaps. The indications, blood supply, advantages, and disadvantages of each are detailed. Incredible progress has been made in the application of microsurgical techniques to the pediatric population over the last several decades. With a healthy understanding of the anatomy and functionality of the donor site, the reconstructive surgeon can repair a variety of complex injuries with an acceptable morbidity and mortality rate.

Evaluation of the quality and value of data sources for postmarket surveillance of the safety of cough and cold medications in children.

BACKGROUND: The purpose of this report is to evaluate the quality of data sources used to study cough and cold medication (CCM) safety in children via the Pediatric Cough and Cold Safety Surveillance System. METHODS: The System utilized the National Poison Data System (NPDS), FDA Adverse Event Reporting System (FAERS), English-language medical literature, manufacturer postmarket safety databases, and news/media reports to identify cases from January 2008 through September 2016. Each data source was evaluated by the proportion of detected cases determined to be eligible (met case criteria) and the proportion determined to be evaluable (able to determine causal relationship between adverse event and exposure). RESULTS: A total of 7184 unique cases were identified from 27,597 detected reports. Of these, 6447 (89.7%) were evaluable. The data source with the highest volume of detected cases was news/media; however, only 0.3% of those cases were eligible for panel review and only 0.2% (24 out of 13,450 cases) were evaluable. The data source with the highest proportion of eligible and evaluable cases was NPDS with 7691 detected cases, 6113 (79.5%) eligible cases, and 5587 (72.6%) evaluable cases. CONCLUSIONS: The data sources utilized to evaluate the safety profile of pediatric CCMs yielded variable detection and evaluation rates, but overall provided a comprehensive look at exposures that otherwise cannot be studied in clinical trials. While this study suggests that each source made a valuable contribution and that evaluable cases are generalizable, improvements are needed in case completeness and accuracy to enhance the quality of postmarket safety evaluations.

The caregiver burden in lupus: findings from UNVEIL, a national online lupus survey in the United States.

OBJECTIVES: Lupus imposes a substantial burden on patients; however, little is known about its impact on those caring for patients with the disease. In this study, we examined the impact 'caring for patients with lupus' has on caregivers from their own perspective. METHODS: UNVEIL was a one-time online national cross-sectional survey developed in partnership with the Lupus Foundation of America and fielded targeting the US Lupus Foundation of America constituents in 2014. Eligible caregivers were adults who self-identified as unpaid caregivers of patients with lupus. Eligible caregivers had to complete a series of sociodemographic questions as well as a series of well established outcome measures, such as the Short Form 12v2 Health Survey, the Work Productivity and Activity Index, the Caregiver Burden Inventory, and the Perceived Benefits of Caregiving Scale. RESULTS: A total of 253 caregivers completed the survey. The majority of caregivers (90.1%) were aged 60 years or younger, more than half (54.2%) were men, and more than half (59.7%) identified themselves as either a spouse or a partner to the patient with lupus they were caring for. Overall health-related quality of life was close to the norm mean of the general US population. Caregivers who were employed missed an average of 12.8% of paid work time due to caregiving responsibilities and reported a 33.5% reduction in on-the-job effectiveness. Nearly half of the caregivers surveyed (49.4%) indicated that their caregiving responsibilities impacted their ability to socialize with friends, and almost all caregivers (97.6%) reported experiencing increased anxiety and stress in relation to their caregiving role. CONCLUSIONS: Caregiving for patients with lupus has a substantial impact on the work productivity and the social and emotional functioning of caregivers. Healthcare professionals and policymakers should continually assess the impact of healthcare decisions on the well-being of those caring for patients with lupus.

Toxicity from repeated doses of acetaminophen in children: assessment of causality and dose in reported cases.

Liver injury has been reported in children treated with repeated doses of acetaminophen. The objective of this study was to identify and validate reports of liver injury or death in children younger than 6 years who were administered repeated therapeutic doses of acetaminophen. We reviewed US Poison Center data, peer-reviewed literature, US Food and Drug Administration Adverse Event Reports, and US Manufacturer Safety Reports describing adverse effects after acetaminophen administration. Reports that described hepatic abnormalities (description of liver injury or abnormal laboratory testing) or death after acetaminophen administration to children younger than 6 years were included. The identified reports were double abstracted and then reviewed by an expert panel to determine if the hepatic injury was related to acetaminophen and whether the dose of acetaminophen was therapeutic (≤75 mg/kg) or supratherapeutic. Our search yielded 2531 reports of adverse events associated with acetaminophen use. From these cases, we identified 76 cases of hepatic injury and 26 deaths associated with repeated acetaminophen administration. There were 6 cases of hepatic abnormalities and no deaths associated with what our panel determined to be therapeutic doses. A large proportion of cases could not be fully evaluated due to incomplete case reporting. Although we identified numerous examples of liver injury and death after repeated doses of acetaminophen, all the deaths and all but 6 cases of hepatic abnormalities involved doses more than 75 mg/kg per day. This study suggests that the doses of less than 75 mg/kg per day of acetaminophen are safe for children younger than 6 years.

Expression of microRNA 210 associates with poor survival and age of tumor onset of soft-tissue sarcoma patients.

Expression of microRNAs can affect age of tumor onset and prognosis of cancer patients. However, nothing is known about the effects of microRNAs on altered age of cancer onset and disease-specific survival of soft-tissue sarcoma (STS) patients. The levels of miR-210, also known as hypoxia-regulated microRNA, were analyzed by quantitative real-time (RT)-PCR in the tumors of 78 STS patients. The patients were stratified according to their microRNA levels with low, intermediate and high expression levels and the association of microRNA expression and patients' survival was analyzed using multivariate Cox's regression hazard analyses. A significant correlation between an intermediate miR-210 expression and disease-specific death of STS patients [relative risk (RR) = 3.19; p = 0.018] was observed compared with patients with high expression levels in their tumors. Interestingly, the association between an intermediate expression of miR-210 and a poor prognosis was only significant in female STS patients (RR = 11.28; p = 0.010), but not observed in male individuals. Furthermore, the expression of miR-210 showed a significant association with the age of tumor onset in a gender-specific manner. Specifically, male patients with an intermediate expression of miR-210 associated with a 9.6-year later age of tumor onset (p = 0.017) compared with males with a low expression of miR-210 in their tumors. However, no significant differences in the female patients were observed. This study provides the first evidence of a correlation of expression levels of a single microRNA (miR-210) with the prognosis and age of tumor onset in a gender-specific manner in STS patients.

The growing impact of pediatric pharmaceutical poisoning.

OBJECTIVE: To understand which medications, under which circumstances, are responsible for the noted increase in pediatric medication poisonings, resource use, and morbidity. STUDY DESIGN: Patient records from 2001-2008 were obtained from the National Poison Data System of the American Association of Poison Control Centers for children aged ≤5 years evaluated in a health care facility following exposure to a potentially toxic dose of a pharmaceutical agent. Pharmaceutical agents were classified as over-the-counter or prescription and by functional category. Exposures were classified as child self-ingested the medication or as therapeutic error. For the 8-year period, emergency visits, admissions, significant injuries, and trends in these events were calculated for each substance category. RESULTS: We evaluated 453 559 children for ingestion of a single pharmaceutical product. Child self-exposure was responsible for 95% of visits. Child self-exposure to prescription products dominated the health care impact with 248 023 of the visits (55%), 41 847 admissions (76%), and 18 191 significant injuries (71%). The greatest resource use and morbidity followed self-ingestion of prescription products, particularly opioids, sedative-hypnotics, and cardiovascular agents. CONCLUSIONS: Prevention efforts have proved to be inadequate in the face of rising availability of prescription medications, particularly more dangerous medications.

Trends in adverse events and related health-care facility utilization from cough and cold medication exposures in children.

INTRODUCTION: Initial research following regulatory changes addressing the pediatric safety of cough and cold medications (CCMs) demonstrated decreases in adverse events (AEs). Using a national multi-source surveillance system, we studied subsequent CCM-related AE case rate trends and associated health-care facility (HCF) evaluation in children. METHODS: Data were collected from 2009 to 2016. Case eligibility included: age <12 years; exposure to an over-the-counter product containing ≥1 CCM pharmaceutical ingredient; ≥1 significant AE that occurred in the United States. RESULTS: About 4756 (72.6%) cases were determined at least potentially related to an index ingredient. Accidental unsupervised ingestions (AUIs; 3134; 65.9%) were the most common case type. Nearly half of AE cases involved children 2 to <4 years old (2,159; 45.4%). The AE case rate did not change significantly over time (p = 0.22). The proportion of AE cases resulting in HCF admission increased from 32.4% (207) in 2009 to 43.4% (238) in 2016 (p < 0.01). Exposures to diphenhydramine (1,305; 67.3%) and/or dextromethorphan (591; 30.5%) were involved in the majority of HCF admissions. CONCLUSIONS: The proportion of AE cases resulting in HCF admission increased from 2009 to 2016. Efforts to prevent AUIs such as packaging innovation and engineering controls, particularly for diphenhydramine and dextromethorphan-containing products, should be pursued.

Pediatric Fatalities Associated With Over-the-Counter Cough and Cold Medications.

BACKGROUND AND OBJECTIVES: In 2008, over-the-counter cough and cold medications (CCMs) underwent labeling changes in response to safety concerns, including fatalities, reported in children exposed to CCMs. The objective of this study is to describe fatalities associated with exposures to CCMs in children <12 years old that were detected by a safety surveillance system from 2008 to 2016. METHODS: Fatalities in children <12 years old that occurred between 2008 and 2016 associated with oral exposure to one or more CCMs were identified by the Pediatric Cough and Cold Safety Surveillance System. An expert panel reviewed all cases to determine the causal relationship between the exposure and death, if the intent of exposure was therapeutic, and if the dose was supratherapeutic. Other contributing factors related to the child's death were also identified as part of a root cause analysis. RESULTS: Of the 180 eligible fatalities captured during the study period, 40 were judged by the expert panel to be either related or potentially related to the CCM. Of these, the majority (n = 24; 60.0%) occurred in children <2 years old and involved nontherapeutic intent (n = 22; 55.0%). The most frequently involved index ingredient was diphenhydramine (n = 28; 70.0%). In 6 cases (n = 6; 15.0%), the CCM was administered to murder the child. In another 7 cases (n = 7; 17.5%), death followed the intentional use of the CCM to sedate the child. CONCLUSIONS: Pediatric fatalities associated with CCMs occurred primarily in young children after deliberate medication administration with nontherapeutic intent by a caregiver.

An innovative sphincter preserving pull-through technique with en bloc colon and small bowel transplantation.

This report describes a new innovative pull-through technique of hindgut reconstruction with en bloc small bowel and colon transplantation in a Crohn's disease patient with irreversible intestinal failure. The approach was intersphincteric and the anastomosis was established between the allograft colon and the recipient anal verge with achievement of full nutritional autonomy and anal continence.

The value of acute toxicity studies to support the clinical management of overdose and poisoning: a cross-discipline consensus.

Acute toxicity studies are no longer required to support first clinical trials of pharmaceuticals in man. However, it is unclear in the wording of the revised ICH M3 whether acute toxicity studies are required later in drug development (e.g., phase 3) in order to support the management of overdose. The NC3Rs held a workshop in January 2010 with representatives from international poison centres, the pharmaceutical and chemical industries, and regulatory and government bodies to explore further whether acute toxicity studies are used to support the clinical management of overdose of pharmaceuticals and whether this work can be translated to other sectors such as the chemical industry. The consensus formed at the workshop was that acute toxicity studies are not used for managing overdose of pharmaceuticals and are of little value in treating human poisoning from chemicals. In this paper, the authors describe the key considerations in treating human overdose and poisoning, challenge the value of the classification and labelling process of chemicals for this purpose and discuss how acute toxicity studies can be improved to better inform risk assessment.

Academic-community partnership: an orientation for employees of a community mental health agency to its research program.

CONTEXT: Community agency employees' interest and involvement in academic-community research partnerships are keys to successful collaborations. One main barrier to success can be employees' lack of knowledge about research. We present data on an "orientation to research" program for community agency employees in a large U.S. city designed to improve knowledge about research in general and that specific to the agency. METHODS: We developed an agency intranet website, a scavenger hunt to facilitate learning through the intranet research website, and a ten-item quantitative knowledge assessment tool. Academic and agency partners were actively involved in the design of the program and its evaluation. FINDINGS: More educated and long-term employees had higher pre-test scores but not post-test scores. Significant improvement in post-test scores was observed for employees after completion of the program. Informal feedback about course content and the academic-community partnership was positive. CONCLUSIONS: This report examines the feasibility of a structured knowledge program targeted at community agency employees at all levels within an agency. We believe that this approach is generalizable to other settings to the extent that there are shared interests, resources, and investment of the academic partner and agency.

Adverse events associated with diphenhydramine in children, 2008-2015.

Introduction: Diphenhydramine (DPH) exposures in children may be the result of accidental unsupervised ingestions, caregiver error, and intentional misuse of DPH-containing cough and cold medications (CCM). We sought to understand the nature of pediatric ingestions of DPH, particularly the toxicity and outcome of a single product, single ingredient DPH (DPH-only) exposures, in order to derive ingredient-specific information about the clinical effects and course of such cases.Methods: As part of a U.S. multi-year safety surveillance program to assess the safety of over-the-counter (OTC) medications used in cough and cold preparations in children <12 years of age, an expert panel reviewed cases involving symptomatic adverse events potentially related to oral exposures to these medications. After individual review, the cases were categorized by causal relationship of the reported ingredients to the adverse event, exposure intent (therapeutic, non-therapeutic, unknown intent), and dose (therapeutic, supratherapeutic, or unknown). Following panel review, any disagreement on classification was discussed until a consensus was reached. The data were then analyzed with respect to descriptive findings.Results: The panel reviewed 6618 eligible cases and determined 2802 were at least potentially related to oral exposure to DPH. Of these, 2028 were DPH-only cases (39.1% of all cases judged at least potentially related to a cough and cold medication). The majority (79.5%) of DPH-only cases occurred in children 2 to <4 years of age and involved accidental unsupervised ingestions (74.7%). Liquid pediatric formulations were the most common (51.7%) products reported followed by solid pediatric formulations (24.0%). The most common adverse events were tachycardia (53.4%), hallucinations (46.5%), somnolence (34.7%), agitation (33.9%), and mydriasis (26.3%). Seizures occurred in only 5.5% of cases. Five (0.2%) deaths were reported; in the death cases, the DPH dose was judged supratherapeutic in one and unknown in the other four. Child abuse was reported in four of the five death cases and three of the five deaths were homicides.Conclusions: Exposures to DPH-only products were the most common type of exposure detected in our study of adverse events associated with CCM in children. The majority of the DPH-only cases were the result of accidental unsupervised ingestions. Most adverse events were relatively mild self-limited anticholinergic effects and few deaths occurred. Deaths involving DPH were often associated with child abuse or homicide. Interventions targeting the prevention of accidental unsupervised are likely to be impactful in preventing morbidity associated with DPH-only exposure.

Medication Errors From Over-the-Counter Cough and Cold Medications in Children.

OBJECTIVE: Out of hospital medication-related adverse events (AEs) from cough and cold medications (CCMs) can have significant public health impact. The objective of this study was to characterize pediatric medication error AEs involving over-the-counter (OTC) CCMs to identify preventable factors. METHODS: Multisource national data surveillance system study using an expert panel evaluating CCM AEs related to medication errors. INCLUSION CRITERIA: age <12 years, and at least 1 significant AE from at least 1 index ingredient from a CCM OTC product. RESULTS: From 2009 through 2016, 4756 cases were determined to have a significant AE related to an OTC CCM ingredient and 513 (10.8%) cases were due to a medication error. Nearly half of medication errors involved children 2 to <6 years old (n = 235; 45.8%). Many involved administration by a parent (n = 231; 45.0%) or alternative caregiver (n = 148; 28.8%). In nearly all cases (93.2%), the medication error involved the wrong dose of the medication. Health care facility evaluation occurred in 381 (74.3%) cases. Diphenhydramine and dextromethorphan were responsible for most medication errors and medication errors involving health care facility evaluation. There were no deaths from medication errors. CONCLUSION: In this multiyear surveillance study, medication errors most commonly occurred in children <6 years old who received the wrong volume of a liquid product. Diphenhydramine and dextromethorphan dosing errors were the most common cause of medication errors resulting from CCM use. Continued standardization of measuring devices, concentrations, and units of measure along with consumer education are needed to further decrease medication errors from CCMs.

Allospecific CD154+ T cells associate with rejection risk after pediatric liver transplantation.

Antigen-specific T cells, which express CD154 rapidly, but remain untested in alloimmunity, were measured with flow cytometry in 16-h MLR of 58 identically-immunosuppressed children with liver transplantation (LTx), to identify Rejectors (who had experienced biopsy-proven rejection within 60 days posttransplantation). Thirty-one children were sampled once, cross-sectionally. Twenty-seven children were sampled longitudinally, pre-LTx, and at 1-60 and 61-200 days after LTx. Results were correlated with proliferative alloresponses measured by CFSE-dye dilution (n = 23), and CTLA4, a negative T-cell costimulator, which antagonizes CD154-mediated effects (n = 31). In cross-sectional observations, logistic regression and leave-one-out cross-validation identified donor-specific, CD154 + T-cytotoxic (Tc)-memory cells as best associated with rejection outcomes. In the longitudinal cohort, (1) the association between CD154 + Tc-memory cells and rejection outcomes was replicated with sensitivity/specificity 92.3%/84.6% for observations at 1-60 days, and (2) elevated pre-LTx CD154 + Tc-memory cell responses were associated with significantly increased incidence (p = 0.02) and hazard (HR = 7.355) of rejection in survival/proportional hazard analysis. CD154 expression correlated with proliferative alloresponses (r = 0.835, p = 7.1e-07), and inversely with CTLA4 expression of allospecific CD154 + Tc-memory cells (r =-0.706, p = 3.0e-05). Allospecific CD154 + T-helper-memory cells, not CD154 + Tc-memory, were inhibited by increasing Tacrolimus concentrations (p = 0.026). Collectively, allospecific CD154 + T cells provide an estimate of rejection risk in children with LTx.

Iceberg discharges into the north atlantic on millennial time scales during the last glaciation.

High-resolution studies of North Atlantic deep sea cores demonstrate that prominent increases in iceberg calving recurred at intervals of 2000 to 3000 years, much more frequently than the 7000-to 10,000-year pacing of massive ice discharges associated with Heinrich events. The calving cycles correlate with warm-cold oscillations, called Dansgaard-Oeschger events, in Greenland ice cores. Each cycle records synchronous discharges of ice from different sources, and the cycles are decoupled from sea-surface temperatures. These findings point to a mechanism operating within the atmosphere that caused rapid oscillations in air temperatures above Greenland and in calving from more than one ice sheet.

Suspended matter in surface waters of the Atlantic continental margin from Cape Cod to the Florida Keys.

Appreciable Amounts Of suspended matter (> 1.0 milligram per liter) in surface waters are restricted to within a few kilometers of the Atlantic coast. Particles that escape estuaries or are discharged by rivers into the shelf region tend to travel longshoreward rather than seaward. Suspended matter farther offshore, chiefly amorphous organic particles, totals 0.1 milligram per liter or less. Soot, fly ash, processed cellulose, and other pollutants are widespread.
