Pediatric Oncology and Obesity: An Introduction for General Pediatricians.

For pediatric patients with cancer, a healthy lifestyle is important for treatment outcomes and beyond. General pediatricians play a major role in the care of these patients, particularly given the improved rates of survival. Pediatric obesity has many negative consequences, but it is an area where primary care providers can make an impact and provide support to childhood cancer survivors. To provide the best quality of care for this population, there must be collaboration between primary care and oncology providers. Additionally, general practioners should feel empowered to offer standard nutrition and physical activity recommendations to all childhood cancer survivors. For pediatric patients who carry a cancer diagnosis, cure is no longer the only goal. Pediatric providers across specialties need to work as a team to improve long-term quality of life for these patients, starting with modifiable healthy habits.

STEP IN: Supporting Together Exercise and Play and Improving Nutrition; a Feasibility Study of Parent-Led Group Sessions and Fitness Trackers to Improve Family Healthy Lifestyle Behaviors in a Low-Income, Predominantly Black Population.

BACKGROUND: Pediatric obesity is prevalent and challenging to treat. Although family-centered behavioral management is the gold standard, many families face structural inequities to its access and efficacy. Identifying ways to manage pediatric obesity within primary care is needed. METHODS: This feasibility study included three sequential trials of peer-led group sessions occurring biweekly or monthly between 3/2016 and 2/2017. Parent-child dyads were recruited from a large academic primary care clinic via mailed invitations, prioritizing patients living in local zip codes of historical disinvestment. Eligible patients were 6 to 12 years with a body mass index ≥85th percentile, with parent and child interest in making healthy lifestyle changes, and English speaking. RESULTS: 27 dyads participated, 77% were non-Hispanic Black. Retention and attendance rates were highest in the initial four-session biweekly pilot (100%, 0 dropouts), high in the full six-session biweekly cohort (83%, 1 dropout), and moderate in the monthly cohort (62.7%, 4 dropouts). Families reported high satisfaction with the sessions (4.75/5). Qualitative comments suggested social connections had motivated behavior change in some families. CONCLUSION: Parent-led group sessions for pediatric weight management show promise in engaging families. A future large trial is needed to assess behavior change and anthropometric outcomes.

A Quality Improvement Initiative Addressing Provider Prescription of Weight Management Follow-up in Primary Care.

INTRODUCTION: Few providers routinely comply with the American Academy of Pediatrics recommendations to prescribe weight management follow-up in-between well-child checks for children with obesity/overweight. This quality improvement (QI) project aimed to increase the percentage of patients prescribed weight management follow-up within three months of their well-child check. METHODS: The project took place in 1 outpatient primary care clinic at a large, free-standing children's hospital from May 2018 to April 2019. We grouped interventions in 4 Plan-Do-Study-Act ramps with the following themes: (1) provider education; (2) electronic health record note changes; (3) discharge order modifications; and (4) provider feedback. The primary outcome was the percent of patients ages 2-18 years with body mass index ≥ 85% that had an order placed to schedule a follow-up weight management appointment in primary care. We monitored attendance rates for scheduled follow-up visits as a balancing measure. RESULTS: Mean prescription rates increased from 32% at baseline to 58%, with special cause analysis demonstrating improvement. Of patients prescribed follow-up, 40% returned for a weight management visit, compared to 13% before the QI initiative. The no-show rate was 35%. CONCLUSIONS: The utilization of QI methodology led to an increase in the percentage of patients appropriately prescribed weight management follow-up and a resultant increase in the number of patients seen for follow-up. The next steps include a re-examination of process failures to improve patient buy-in in follow-up prescriptions.

Relationship between extreme obesity and mortality in patients with reduced ejection fraction.

AIMS: Although obesity is associated with increased mortality, epidemiologic studies in heart failure have reported lower mortality in obese patients compared with matched nonobese patients (the 'obesity paradox'). However, the relationship between survival and extreme (morbid) obesity (BMI ≥ 40) is poorly understood. We evaluate survival in low ejection fraction patients across a range of BMI categories, including extreme obesity. METHODS: In a retrospective review, 12 181 consecutive patients receiving nuclear stress testing at a tertiary care center were stratified based on BMI and ejection fraction. Eight-year mortality data were collected using the social security death index. RESULTS: Normal ejection fraction patients (internal control, ejection fraction ≥50%) exhibited the J-shaped association between mortality and BMI that is observed in the general population. Among patients with reduced ejection fraction (<50%), survival improved as obesity increased (P < 0.0001). Those with extreme obesity had the lowest mortality (n = 1134, P < 0.05). CONCLUSION: In this cohort of reduced Ejection fraction patients, the obesity paradox was observed in all weight categories, with the highest survival of all observed in the extremely obese BMI category. This further supports hypotheses that an obesity-related physiologic phenomenon affects mortality in reduced ejection fraction patients.

Torsemide versus furosemide and intermediate-term outcomes in patients with heart failure: an updated meta-analysis.

AIMS: Loop diuretics have become a mainstay of chronic heart failure management. Furosemide and torsemide are the two most common loop diuretics; nevertheless, there is inconsistent evidence regarding the optimal choice of loop diuretic with respect to clinical outcomes. METHODS: Medline and Cochrane Databases were systemically reviewed for randomized and observational studies comparing patients with chronic heart failure on oral torsemide versus oral furosemide and their association with intermediate-term outcomes (5-12 months) through May 2018. Odds ratios with corresponding 95% confidence intervals (CIs) were used for outcomes. A random effect model was used to account for heterogeneity among studies. Heterogeneity was assessed with the Higgins I-square statistic. RESULTS: A total of 8127 patients were included in the analysis from a total of 14 studies (10 randomized, four observational); 5729 patients were prescribed furosemide and 2398 were given torsemide. There was no significant difference in intermediate-term mortality among heart failure patients on furosemide compared with torsemide [odds ratio (OR) 1.01, CI 0.64-1.59, I = 65.8%]; however, furosemide was associated with an increased risk of heart failure readmissions (OR 2.16, CI 1.28-2.64, I = 0.0%). Heart failure patients taking torsemide were more likely to have an improvement in New York Heart Association class compared with those on furosemide (OR 0.73, CI 0.58-0.93, I = 19.6%). CONCLUSION: Torsemide is associated with a reduction in intermediate-term heart failure readmissions and improvement in New York Heart Association class compared with furosemide but is not associated with a reduced mortality risk. Additional randomized trials are needed to examine the impact of loop diuretics on clinical outcomes in patients with heart failure.

A Pilot Study of School-Based Comprehensive Cardiovascular Screening in Middle School Children.

Although recommended, most children are not routinely screened for lipid abnormalities and diabetes. We report a pilot of universal screening for diabetes, lipid abnormalities, and hypertension in the middle-school setting. Of 45 children screened, 34.8% had lipid or hemoglobin A1c abnormalities and 2 had hemoglobin A1c values in the diabetes range.

Severe Obesity in Children May Not Pose Independent Risk for Influenza Complications.

PURPOSE: Subsets of children are targeted for influenza vaccination due to known conditions that increase the risk of influenza complications. The purpose of this study was to determine if severe obesity in children suggests targeted vaccination. DESIGN AND METHODS: A retrospective chart review of a large Midwestern pediatric hospital identified 188 cases of influenza complications (defined as requiring hospitalization or death) aged 2 to <20 years old from August 1, 2010 through June 30, 2013. Severe obesity was defined as body mass index (BMI) ≥99% for age and gender, with patients grouped by severe obesity status (yes vs. no). Cases were reviewed for previously identified risk conditions for influenza complications (e.g., asthma, pneumonia, diabetes), and were classified as having or not having a known high risk condition. RESULTS: Of 188 cases, 174 (93%) had a high-risk condition, while only 14 (7%) had no known condition. All 14 (100%) with no known high-risk condition had a BMI <99%. All 15 (100%) with BMI ≥99% had a known high-risk condition. The association between severe obesity status and influenza complications was not statistically significant (p = 0.61). CONCLUSIONS: This suggests that severe obesity in children is not an independent high-risk condition for influenza complications defined as requiring hospitalization or resulting in death, once other known influenza risk factors are considered. IMPLICATIONS: Based on this data, clinicians should not target children for influenza vaccination based on weight status. We cannot comment about whether severe obesity represents increased risk for less severe cases of influenza.

Community Healthcare and Technology to Enhance Communication in Pediatric Obesity Care.

Childhood obesity continues to be a critical healthcare issue and a paradigm of a pervasive chronic disease affecting even our youngest children. When considered within the context of the socioecological model, the factors that influence weight status, including the social determinants of health, limit the impact of multidisciplinary care that occurs solely within the medical setting. Coordinated care that incorporates communication between the healthcare and community sectors is necessary to more effectively prevent and treat obesity. In this article, the Expert Exchange authors, with input from providers convened at an international pediatric meeting, provide recommendations to address this critical issue. These recommendations draw upon examples from the management of other chronic conditions that might be applied to the treatment of obesity, such as the use of care plans and health assessment forms to allow weight management specialists and community personnel (e.g., school counselors) to communicate about treatment recommendations and responses. To facilitate communication across the healthcare and community sectors, practical considerations regarding the development and/or evaluation of communication tools are presented. In addition, the use of technology to enhance healthcare-community communication is explored as a means to decrease the barriers to collaboration and to create a web of connection between the community and healthcare providers that promote wellness and a healthy weight status.

Obesity class does not further stratify outcome in overweight and obese pediatric patients after heart transplantation.

The effect of obesity stratification on pediatric heart transplant outcomes is unknown. The UNOS database was queried for patients ≥2-<18 years listed for heart transplant and stratified by BMI: normal (BMI>5%-≤85 percentile), overweight (BMI=86%-95 percentile), class 1 (BMI=100%-120% of 95 percentile), class 2 (BMI=121%-140% of 95 percentile), and class 3 obesity (BMI>140% of 95 percentile). A total of 5056 individuals were listed for transplant, with 71% normal, 13% overweight, 10% class 1, 4% class 2, and 2% class 3 obesity. Waitlist survival was not different between groups. Post-transplant survival was decreased in overweight and combined obese groups vs normal, with no further difference between overweight and obese classes. Overweight and obese patients had higher listing status and were more likely to have ventilator, inotrope, and mechanical circulatory support at listing. After transplant, there was an association of overweight-obese patients with diabetes and rejection requiring hospitalization. Stricter definition of normal weight reveals overweight-obese status was an independent risk factor for poorer post-transplant survival, without further effect by stratification of weight class. However, because there is no difference in waitlist survival, this study does not allow the selection of absolute weight-based criteria regarding transplant listing and suggests the need to look further for modifiable risk factors post-transplant.

Nudging Healthier Choices in a Hospital Cafeteria: Results From a Field Study.

More than two thirds of adults and one third of children are overweight or obese in the United States. These trends have led to initiatives to provide information that supports informed choices. Traffic light labeling has been shown to increase consumer awareness and encourage healthy selections. This article contributes to the literature on healthy choices by comparing the additional contribution of a number of interventions used in combination with traffic light labeling. We conducted a 21-month field study in a workplace cafeteria. We analyzed cash register receipts, focusing on sales of beverages and chips. We found that the traffic light system was effective. The addition of caloric information to traffic light labeling had a positive effect on the purchase of healthy chips. However, other interventions appeared to produce more harm than good, essentially wiping out the benefits from traffic light labeling. These findings suggest that although it is possible to improve on traffic light labeling with selective interventions, caution is in order as some interventions may trigger compensatory behavior that results in the purchase of unhealthy items.

Psychosocial Screening Among Youth Seeking Weight Management Treatment.

The objectives of this study were to identify rates of, and factors associated with, "at-risk" scores on a brief psychosocial screener among overweight/obese youth seeking weight management treatment, as well as concordance between youth and caregiver reports. A retrospective chart review of 1443 consecutive patients ages 4 to 18 years and their caregivers was conducted. Almost 1 in 4 youth with overweight/obesity presented with psychosocial symptoms in the at-risk range for significant mental health issues based on caregiver report on the Pediatric Symptom Checklist (PSC) and 1 in 6 based on youth self-report on the Youth Pediatric Symptom Checklist (Y-PSC). Concordance between caregiver and youth was fair (agreement 24% to 40%). Higher scores were associated with male sex and older age on the PSC and with indication of depressive disorder in the electronic medical record on the Y-PSC. Conducting a brief psychosocial screen in comprehensive weight management programs is feasible and clinically indicated.

Challenges in Screening for Pediatric Nonalcoholic Fatty Liver Disease.

Nonalcoholic fatty liver disease (NAFLD) is the most common cause of elevated liver enzymes in children in the United States. Screening for NAFLD in children with obesity is recommended by several published guidelines, but the application of these recommendations in pediatric weight management programs is uncertain. Our study aimed to describe the screening practices for NAFLD in a large pediatric weight management program. During 2014, 1312 patients were seen, with a liver enzyme panel obtained in 847 (64.5%). Only 47/847 (5.5%) had elevated liver enzymes twice the upper limit of normal. Of the 47, 33 (70%) patients had persistently elevated liver enzymes. Of those 33, 22 (67%) had further exclusionary laboratory testing. Screening for NAFLD is challenging even in a pediatric weight management program with clearly established protocols. Those with elevated liver enzymes do not always complete recommended exclusionary testing. Barriers to completing further evaluation need to be addressed.

Small Prizes Improve Food Selection in a School Cafeteria Without Increasing Waste.

We recently demonstrated that small prizes given for a "Power Plate" (plain fat-free milk, entrée, fruit and vegetable) can be used in an elementary school cafeteria to increase healthful food selection by over 300%. The purpose of this study was to measure changes in food waste when the Power Plate (PP) program is implemented. The PP intervention was conducted at an inner-city elementary school. Emoticons were placed next to the preferred foods and children were given a small prize if they selected the PP. Data were obtained by observation and cash register receipts. The trays of 111 students before the intervention and 96 after were examined for content and waste. PP selection increased from 2% to 73% ( P < .001). There was no significant change in waste. We conclude that small prizes as an incentive for better food selection does not lead to an increase food waste.

Severe Obesity Decreasing in Children in Cincinnati, Ohio.

Childhood obesity rates appear to be leveling off. Studies not looking at severe obesity may be masking a rightward shift in the distribution of body mass indexes. Our objective was to provide current prevalence rates and examine trends in overweight, obesity, class 2 obesity, and class 3 obesity for youth in Cincinnati, Ohio. We performed a retrospective chart review of children 2 to 18 years old seen at Cincinnati Children's Hospital Medical Center between July 1, 2011, and June 30, 2014. Data from 217 037 BMIs were obtained; 35.2% of children were found to have an elevated BMI. Prevalence rates were highest in older, Hispanic, and Medicaid-insured children. The only significant trend over the 3-year period was a downward shift in class 3 obesity ( P = .02), contrary to national findings. Further studies assessing which clinical/community efforts have led to this downward trend will be essential to target future resources and facilitate continued progress.

Using weight-for-age percentiles to screen for overweight and obese children and adolescents.

There are relatively low rates of screening for overweight and obesity among children and adolescents in primary care. A simplified method for such screening is needed. The study objective was to examine if weight-for-age percentiles are sufficiently sensitive in identifying overweight and obesity in children and adolescents. We used data from two distinct sources: four consecutive cycles of the National Health and Nutrition Examination Surveys (NHANES) from the years 2005 to 2012, using participants aged 2-17.9 years for whom data on age, sex, weight, and height were available (n=12,884), and primary care clinic measurements (n=15,152). Primary outcomes were the threshold values of weight-for-age percentiles which best discriminated between normal weight, overweight, and obesity status. Receiver operating characteristic analyses demonstrated that weight-for-age percentiles well discriminated between normal weight and overweight and between non-obese and obese individuals (area under curve=0.956 and 0.977, respectively, both p<0.001). Following Classification and Regression Trees analysis, the 90th and 75th weight-for-age percentiles were chosen as appropriate cutoffs for obesity and overweight, respectively. These cutoffs had high sensitivity and negative predictive value in identifying obese participants (94.3% and 98.6%, respectively, for the 90th percentile) and in identifying overweight participants (93.2% and 95.9%, respectively, for the 75th percentile). The sensitivities and specificities were nearly identical across race and sex, and in the validation data from NHANES 2011 to 2012 and primary care. We conclude that weight-for-age percentiles can discriminate between normal weight, overweight and obese children, and adolescents. The 75th and 90th weight-for-age percentiles correspond well with the BMI cutoffs for pediatric overweight and obesity, respectively.
