BACKGROUND: Fundoplication is often performed in conjunction with gastrostomy tube (GT) placement in children, but there is a great deal of variation in rates of and indications for this procedure. Little is known about the impact of fundoplication on peri-operative outcomes. This study examines a national cohort of pediatric patients to compare risk-adjusted surgical outcomes in patients undergoing GT placement with or without concomitant fundoplication. METHODS: We identified all patients undergoing GT placement in the 2012 National Surgical Quality Improvement Program - Pediatric. We evaluated demographics, comorbidities, complications, and length of stay for GT with fundoplication versus GT alone. We defined composite morbidity as a dichotomous variable for the presence of any complication. Logistic regression was performed to identify predictors of morbidity after adjusting for covariates. RESULTS: 1289 GT patients were identified, and 148 (11.5%) underwent concurrent fundoplication. The fundoplication patients were more likely to be younger, have cardiac risk factors, and be on respiratory support. They also had higher rates of surgical site infection (7.4% vs 3.7%, p=0.03) and composite morbidity (16.9% vs 8.7%, p=0.001), and longer LOS (median 5 vs 3 days, p=<0.0001) compared to GT only. After adjusting for covariates, fundoplication was a predictor of composite morbidity and increased LOS. CONCLUSION: Concomitant fundoplication is an independent risk factor for 30-day post-operative morbidity in patients undergoing GT placement. These findings do not negate the value of fundoplication but underscore the importance of careful patient selection, and should be taken into consideration when discussing risks and benefits with families.

OBJECTIVES: Understanding the factors associated with child communication during subspecialty encounters may inform interventions promoting shared decision-making in chronic disease management. Objectives were to (1) describe the quantity and quality of child communication during outpatient subspecialty encounters and (2) determine if and how the quantity and quality of child communication vary by demographic and visit characteristics. METHODS: We videotaped subspecialty clinic encounters involving 20 health care providers and 155 children with one of the following conditions: acute lymphoblastic leukemia (consolidation/maintenance), persistent asthma, cystic fibrosis, type 1 diabetes, and obesity. The Roter interaction analysis system was used to code child utterances into one of 10 discrete categories. RESULTS: Children exhibited a mean of 15% of all utterances made during clinical encounters. Children spoke more during obesity encounters. CONCLUSIONS: Similar to the findings of studies in primary care settings, children spoke infrequently during the subspecialty visits, and the most common utterances tended to be replies to questions from adults. PRACTICE IMPLICATIONS: In this study, there was relatively higher engagement of children during obesity clinic encounters in the area of lifestyle choices. Strategies used to engage children in conversation in obesity clinics may be useful for engaging children in other subspecialty clinics.

BACKGROUND: Advance care planning may help patients receive treatments that better align with their goals for care. We developed a Web-based decision aid called InformedTogether to facilitate shared advance care planning between chronic obstructive pulmonary disease (COPD) patients and their doctors. OBJECTIVE: Our objective was to assess the usability of the InformedTogether decision aid, including whether users could interact with the decision aid to engage in tasks required for shared decision making, whether users found the decision aid acceptable, and implications for redesign. METHODS: We conducted an observational study with 15 patients and 8 doctors at two ethnically and socioeconomically diverse outpatient clinics. Data included quantitative and qualitative observations of patients and doctors using the decision aid on tablet or laptop computers and data from semistructured interviews. Patients were shown the decision aid by a researcher acting as the doctor. Pulmonary doctors were observed using the decision aid independently and asked to think aloud (ie, verbalize their thoughts). A thematic analysis was implemented to explore key issues related to decision aid usability. RESULTS: Although patients and doctors found InformedTogether acceptable and would recommend that doctors use the decision aid with COPD patients, many patients had difficulty understanding the icon arrays that were used to communicate estimated prognoses and could not articulate the definitions of the two treatment choices-Full Code and Do Not Resuscitate (DNR). Minor usability problems regarding content, links, layout, and consistency were also identified and corresponding recommendations were outlined. In particular, participants suggested including more information about potential changes in quality of life resulting from the alternative advance directives. Some doctor participants thought the decision aid was too long and some thought it may cause nervousness among patients due to the topic area. CONCLUSIONS: A decision aid for shared advance care planning for severe COPD was found acceptable to most COPD patients and their doctors. However, many patient participants did not demonstrate understanding of the treatment options or prognostic estimates. Many participants endorsed the use of the decision aid between doctors and their patients with COPD, although they desired more information about quality of life. The design must optimize comprehensibility, including revising the presentation of statistical information in the icon array, and feasibility of integration into clinical workflow, including shortening the decision aid.

OBJECTIVE: Maternal prepregnancy obesity is associated with several poor infant health outcomes; however, studies that investigated motor development have been inconsistent. Thus, maternal prepregnancy weight status and infants' gross motor development were examined. METHODS: Participants consisted of 4,901 mother-infant pairs from the Upstate KIDS study, a longitudinal cohort in New York. Mothers indicated dates when infants achieved each of six gross motor milestones when infants were 4, 8, 12, 18, and 24 months old. Failure time modeling under a Weibull distribution was utilized to compare time to achievement across three levels of maternal prepregnancy BMI. Hazard ratios (HR) below one indicate a lower "risk" of achieving the milestone and translate to later achievement. RESULTS: Compared to infants born to thin and normal-weight mothers (BMI < 25), infants born to mothers with obesity (BMI > 30) were slower to sit without support (HR = 0.91, P = 0.03) and crawl on hands and knees (HR = 0.86, P < 0.001), after adjusting for maternal and birth characteristics. Increased gestational age was associated with faster achievement of all milestones, but additional adjustment did not impact results. CONCLUSIONS: Maternal prepregnancy obesity was associated with a slightly longer time for infant to sit and crawl, potentially due to a compromised intrauterine environment or reduced physically active play.

The field of "salivary diagnostics" includes studies utilizing samples obtained from a variety of sources within the oral cavity. These samples include; whole unstimulated saliva, stimulated whole saliva, duct saliva collected directly from the parotid, submandibular/sublingual glands or minor salivary glands, swabs of the buccal mucosa, tongue or tonsils, and gingival crevicular fluid. Many publications state "we collected saliva from subjects" without fully describing the process or source of the oral fluid. Factors that need to be documented in any study include the time of day of the collection, the method used to stimulate and collect the fluid, and how much fluid is being collected and for how long. The handling of the oral fluid during and post-collection is also critical and may include addition of protease or nuclease inhibitors, centrifugation, and cold or frozen storage prior to assay. In an effort to create a standard protocol for determining a biomarker's origin we carried out a pilot study collecting oral fluid from 5 different sites in the mouth and monitoring the concentrations of pro-and anti-inflammatory cytokines detected using MesoScaleDiscovery (MSD) electrochemiluminesence assays. Our data suggested that 3 of the cytokines are primarily derived from the submandibular gland, while 7 of the cytokines come from a source other than the major salivary glands such as the minor salivary glands or cells in the oral mucosae. Here we review the literature on monitoring biomarkers in oral samples and stress the need for determining the blood/saliva ratio when a quantitative determination is needed and suggest that the term oral diagnostic be used if the source of an analyte in the oral cavity is unknown.
