Survivors of Congenital Diaphragmatic Hernia Repair Face Barriers to Long-Term Follow-Up Care.

BACKGROUND: Congenital diaphragmatic hernia (CDH) carries high morbidity and mortality, and survivors commonly have neurodevelopmental, gastrointestinal, and pulmonary sequela requiring multidisciplinary care well beyond repair. We predict that following hospitalization for repair, CDH survivors face many barriers to receiving future medical care. METHODS: A retrospective review was conducted of all living CDH patients between ages 0 to 12 years who underwent repair at Riley Hospital for Children (RHC) from 2010 through 2019. Follow-up status with specialty providers was reviewed, and all eligible families were contacted to complete a survey regarding various aspects of their child's care, including functional status, quality of life, and barriers to care. Bivariate analysis was applied to patient data (P < 0.05 was significant) and survey responses were analyzed qualitatively. RESULTS: After exclusions, 70 survivors were contacted. Thirty-three (47%) were deemed lost to follow up to specialist providers, and were similar to those who maintained follow-up with respect to defect severity type (A-D, P = 0.57), ECMO use (P = 0.35), number of affected organ systems (P = 0.36), and number of providers following after discharge (P = 0.33). Seventeen (24%) families completed the survey, of whom eight (47%) were deemed lost to follow up to specialist providers. Families reported distance and time constraints, access to CDH-specific information and care, access to CDH-specific resources, and access to healthcare as significant barriers to care. All respondents were interested in a multidisciplinary CDH clinic. CONCLUSIONS: CDH survivors require multidisciplinary care beyond initial repair, but attrition to follow-up after discharge is high. A multidisciplinary CDH clinic may address caregivers' perceived barriers.

EMG Testing throughout behavioral recovery after rat sciatic nerve crush injury results in exuberant motoneuron dendritic hypertrophy.

Background: Peripheral nerve injury (PNI) is the most common type of nerve trauma yet, while injured motoneurons exhibit a robust capacity for regeneration, behavioral recovery is protracted and typically poor. Neurotherapeutic approaches to PNI and repair have primarily focused on the enhancement of axonal regeneration, in terms of rate, axonal sprouting, and reconnection connectivity. Both electrical stimulation (ES) and treatment with androgens [e.g., testosterone propionate (TP)] have been demonstrated to enhance axonal sprouting, regeneration rate and functional recovery following PNI. To date, very little work has been done to examine the effects of ES and/or TP on dendritic morphology and organization within the spinal cord after PNI. Objective: The objective of the current study was to examine the impact of treatment with TP and ES, alone or in combination, on the dendritic arbor of spinal motoneurons after target disconnection via sciatic nerve crush injury in the rat. Methods: Rats received a crush injury to the sciatic nerve. Following injury, some animals received either (1) no further treatment beyond implantation with empty Silastic capsules, (2) electrical nerve stimulation immediately after injury, (3) implantation with Silastic capsules filled with TP, or (4) electrical nerve stimulation immediately after injury as well as implantation with TP. All of these groups of axotomized animals also received bi-weekly electromyography (EMG) testing. Additional groups of intact untreated animals as well as a group of injured animals who received no further treatment or EMG testing were also included. Eight weeks after injury, motoneurons innervating the anterior tibialis muscle were labeled with cholera toxin-conjugated horseradish peroxidase, and dendritic arbors were reconstructed in three dimensions. Results: After nerve crush and ES and/or TP treatment, motoneurons innervating the anterior tibialis underwent marked dendritic hypertrophy. Surprisingly, this dendritic hypertrophy occurred in all animals receiving repeated bi-weekly EMG testing, regardless of treatment. When the EMG testing was eliminated, the dendritic arbor extent and distribution after nerve crush in the treated groups did not significantly differ from intact untreated animals. Conclusions: The ability of repeated EMG testing to so dramatically affect central plasticity following a peripheral nerve injury was unexpected. It was also unexpected that gonadal steroid hormones and/or ES, two neurotherapeutic approaches with demonstrated molecular/behavioral changes consistent with peripheral improvements in axonal repair and target reconnection, do not appear to impact central plasticity in a similar manner. The significance of peripheral EMG testing and resulting central plasticity reorganization remains to be determined.

Effects of music intervention on inflammatory markers in critically ill and post-operative patients: A systematic review of the literature.

BACKGROUND: Music listening has been shown to reduce anxiety, stress, and patient tolerance of procedures. Music may also have beneficial effects on inflammatory biomarkers in intensive care and post-operative patients, but the quality of evidence is not clear. OBJECTIVES: We conducted a systematic review to evaluate the effects of music on inflammatory biomarkers in intensive care, and post-operative patients. METHODS: A comprehensive search of the literature was performed. After screening 1570 references, full text review of 26 studies was performed. Fourteen studies were selected for inclusion. RESULTS: Seven studies showed a significant decrease in cortisol levels, but the level of evidence was low. Three studies had low risk of methodological bias, while 11 studies had high risk of bias. CONCLUSIONS: Music intervention may decrease cortisol levels, but other biomarkers remain unchanged. Given the low level of evidence, further research on music effects on inflammatory biomarkers is needed.
