ABSTRACT

OBJECTIVES: To quantify and identify factors associated with bleeding events during pediatric extracorporeal membrane oxygenation. DESIGN: Retrospective cohort study with primary outcome of bleeding days on extracorporeal membrane oxygenation. SETTING: Single tertiary care children's hospital. SUBJECTS: One-hundred twenty-two children supported with extracorporeal membrane oxygenation for greater than 12 hours during January 2015 through December 2016. INTERVENTIONS: Bleeding days were identified if mediastinal or cannula site exploration, activated factor VII administration, gastrointestinal, pulmonary, or intracranial hemorrhages occurred. Logistic regression was used to assess factors associated with bleeding days. MEASUREMENTS AND MAIN RESULTS: Study population was identified from institutional extracorporeal membrane oxygenation database. Clinical, laboratory, and survival data were obtained from medical records. Only data from patients' first extracorporeal membrane oxygenation run were used. One-hundred twenty-two patients with median age of 17 weeks (interquartile range, 1-148 wk) were analyzed. Congenital heart disease (n = 56, 46%) was the most common diagnosis. Bleeding days comprised 179 (16%) of the 1,121 observed extracorporeal membrane oxygenation-patient-days. By extracorporeal membrane oxygenation day 4, 50% of users had experienced a bleeding day. Central rather than peripheral cannulation (odds ratio, 2.58; 95% CI, 1.47-4.52; p < 0.001), older age (odds ratio, 1.31 per increased week; 95% CI, 1.14-1.52; p < 0.001), higher lactate (odds ratio, 1.08 per 1 mmol/L increase; 95% CI, 1.05-1.12; p < 0.001), and lower platelets (odds ratio, 0.87 per 25,000 cell/µL increase; 95% CI, 0.77-0.99; p = 0.005) were associated with bleeding days. Patients who experienced more frequent bleeding (> 75th percentile) had fewer ventilator-free and hospital-free days in the 60 days after cannulation (0 vs 31; p = 0.002 and 0 vs 0; p = 0.008) and higher in-hospital mortality (68 vs 34%; p < 0.001). CONCLUSIONS: Central cannulation, older age, low platelets, and high lactate are associated with bleeding days during pediatric extracorporeal membrane oxygenation. Patients who bleed more frequently during extracorporeal membrane oxygenation have higher in-hospital mortality, longer technological dependence, and reduced hospital-free days.

ABSTRACT

The latest research cumulates staggering information about the correlation between the microbiota-gut-brain axis and neurodevelopmental disorders. This review aims to shed light on the potential influence of the microbiome on the development of the most prevalent neurodevelopmental disease, attention-deficit-hyperactive disorder (ADHD). As the etiology and pathophysiology of ADHD are still unclear, finding viable biomarkers and effective treatment still represent a challenge. Therefore, we focused on factors that have been associated with a higher risk of developing ADHD, while simultaneously influencing the microbial composition. We reviewed the effect of a differing microbial makeup on neurotransmitter concentrations important in the pathophysiology of ADHD. Additionally, we deduced factors that correlate with a high prevalence of ADHD, while simultaneously affecting the gut microbiome, such as emergency c-sections, and premature birth as the former leads to a decrease of the gut microbial diversity and the latter causes neuroprotective Lactobacillus levels to be reduced. Also, we assessed nutritional influences, such as breastfeeding, ingestion of short-chain fatty acids (SCFAs) and polyunsaturated fatty acids (PUFAs) on the host's microbiome and development of ADHD. Finally, we discussed the potential significance of Bifidobacterium as a biomarker for ADHD, the importance of preventing premature birth as prophylaxis and nutrition as a prospective therapeutic measurement against ADHD.

ABSTRACT

OBJECTIVES: To quantify and identify factors associated with large RBC exposure in children supported with extracorporeal membrane oxygenation. DESIGN: Retrospective cohort study. SETTING: Single tertiary care children's hospital. PATIENTS: One-hundred twenty-two children supported with extracorporeal membrane oxygenation for greater than 12 hours during January 1, 2015, to December 31, 2016. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Clinical, laboratory, and survival data were obtained from medical records. Only data from patients' first extracorporeal membrane oxygenation run were used. The primary outcome was RBC volume exposure during extracorporeal membrane oxygenation (mL/kg/d). Patients with RBC exposure volume greater than 75th percentile were categorized as "high RBC use" patients. A "bleeding day" was identified if mediastinum or cannula sites were explored and/or Factor VIIa administration, gastrointestinal, pulmonary, or intracranial hemorrhages occurred. Median age was 0.3 years (interquartile range, 0-3 yr). Congenital heart disease (n = 56; 46%) was the most common diagnosis. Median RBC volume transfused during extracorporeal membrane oxygenation was 39 mL/kg/d (interquartile range, 21-66 mL/kg/d). High RBC use patients were more likely be supported by venoarterial extracorporeal membrane oxygenation (100 vs 76%; p = 0.006), have congenital heart disease (68 vs 39%; p = 0.02), and experience bleeding (33 vs 11% d; p < 0.001). High RBC use patients showed a trend toward higher in-hospital mortality (58 vs 37%; p = 0.07). In the multivariable analysis, younger age (-9% per year; 95% CI, -10% to -7%; p < 0.001), more blood draws per day (+8%; 95% CI, 6-11%; p < 0.001), and higher proportion of bleeding days (+22% per 10% increase; 95% CI, 16-29%; p < 0.001) were associated with larger RBC exposure (model R = 0.66). CONCLUSIONS: Bleeding during extracorporeal membrane oxygenation, frequent laboratory draws, and younger age were associated with increased RBC exposure during extracorporeal membrane oxygenation. Higher transfusion volume was associated with increased mortality.

ABSTRACT

INTRODUCTION: Older individuals who have survived cancer and the commensurate treatment often experience a reduced quality of life in part due to their impaired muscular abilities and deficits in mobility. The purpose of this preliminary study was to determine the feasibility and preliminary efficacy of resistance exercise via negative, eccentrically induced work (RENEW) with older cancer survivors. METHODS: Older cancer survivors with a perception of moderate muscle weakness and fatigue participated in 12 weeks of RENEW. Measures of feasibility included (1) the participant's ability to progress the total amount of work of RENEW; (2) whether peak knee extension torque production became impaired; and (3) whether RENEW induced leg muscle pain as measured on a visual analog scale. The preliminary measure of efficacy included the performance of a timed up-and-go mobility test. RESULTS: The participants significantly increased the total average work per week over the 12 weeks of RENEW. Participants increased (P < .001) their work approximately 3-fold from week 3 (7.6 [5.11 kJ) to week 12 (22.1 [14.8] kJ) without muscle pain over the 12-week RENEW training period. Knee extension peak torque production improved (11%) significantly (P = .02) (pretest: 248 [92] N; posttest: 275 [99] N) after 12 weeks of RENEW. The time to perform the up-and-go test improved (14%) significantly (P < .001) (pretest: 8.4 [2.7]; posttest: 7.2 [2.3] s) after 12 weeks of RENEW, suggesting preliminary efficacy. CONCLUSION: Collectively, RENEW appears feasible and potentially efficacious for older, weak, and fatigued cancer survivors. IMPLICATIONS FOR CANCER SURVIVORS: The use of eccentric muscle exercise may be ideally suited for older cancer survivors due to its high force and low energetic-cost capabilities.
