Barriers and characteristics for successful transition to adult healthcare for individuals with cerebral palsy: a systematic review

Abstract

Background: Cerebral palsy (CP) is a common childhood disability. However, these individuals are now living longer lives, participating in adult roles, and seeking healthcare services. The transition from pediatric to adult healthcare for adolescents with CP is a challenging yet significant time. Adolescents experience several barriers during transition.

Objectives: To utilize the environmental and personal dimensions of the ICF model in order to explore barriers when transitioning to adulthood as well as discuss characteristics and physical therapy implications needed to succeed within transition.

Methods: Electronic searching of PubMed, CINAHL, ERIC, Scopus, ProQuest, and the Cochrane Library databases was concluded on January 9, 2019 for studies including transition between pediatric and adult healthcare in individuals diagnosed with CP. Two independent reviewers agreed upon inclusion, eligibility, and quality assessment of each study using the Mixed-Methods Appraisal Tool (MMAT).

Results: Seven studies were included in the systematic review. Results for each study were separated based on the personal and environmental contextual factors of the ICF model and solutions to the barriers were then discussed.

Conclusions: Research has provided proposed solutions to select barriers, however, other barriers have yet to be addressed. More research is needed to address these barriers and provide a model program that can be implemented within the healthcare systems to promote a successful transition for adolescents with CP from pediatric to adult services.     

Aortogastric fistula from hiatal hernia ulcer. A cause of massive upper gastrointestinal bleeding

An 83-year-old woman with no history of vascular surgery presented with a fatal upper gastrointestinal bleed from an aortogastric fistula secondary to a penetrating gastric ulcer. The fistula was between the thoracic aorta and the gastric ulcer in a hiatus hernia. On autopsy, a discrete 1-cm ulcer had perforated into the otherwise normal thoracic aorta. Aortogastric fistula involving the thoracic aorta and a gastric ulcer is rare in the absence of vascular graft surgery or aneurysm. We review the pertinent literature.     

Deprivation of parenting disrupts development of homeostatic and reward systems in marmoset monkey offspring.

BACKGROUND: Early environment is a major determinant of long-term mental health, evidenced by the relationship between early-life neglect or abuse and chronically increased vulnerability to developmental psychopathology, including major depressive disorder (MDD). Animal studies can increase understanding of environmentally mediated causal risk processes. We describe how daily deprivation of biological parenting in primate infants disrupts development of homeostatic and reward systems central to MDD. METHODS: Nine breeding pairs of marmoset monkeys provided control twins (CON) and early-deprived twins (ED); the latter were socially isolated for 30-120 min/day on days 2-28. During the first year of life, basal urinary norepinephrine (NE) titers and cardiophysiologic activity were measured. At the end of year 1 (adolescence), automated neuropsychologic tests were conducted to measure responsiveness to changes in stimulus-reward association (simple/reversed visual discrimination learning) and to reward per se (progressive ratio [PR] reinforcement schedule). RESULTS: The ED monkeys exhibited increased basal urinary NE titers and increased systolic blood pressure relative to CON siblings. The ED monkeys required more sessions to reinstate stimulus-oriented behavior following reversal, suggesting increased vulnerability to perceived loss of environmental control; ED monkeys also performed less PR operant responses, indicating that reward was less of an incentive and that they were mildly anhedonic relative to CON. CONCLUSIONS: In marmoset monkeys, neglect-like manipulation of ED leads to chronic changes in homeostatic systems, similar to those in children and adolescents exposed to early-life adversity and in MDD, and to responses to environmental stimuli similar to those that characterize MDD.     

In vivo measurements show tensile axial strain in the proximal lateral aspect of the human femur

Two conflicting theories exist concerning the stress pattern for the proximal lateral aspect of the human femur. According to the classic theory of Pauwels, a bending moment on the femur leads to compression medially and to tension laterally. The alternative theory is that muscle forces contribute to a moment-free loading of the femur, with both the medial and lateral cortices subjected to compression. To examine these theories, we measured the strain at the external surface of the proximal lateral aspect of the femur of two female patients undergoing surgery for “snapping hip syndrome.” During the surgical procedure, a strain-gauge rosette was bonded to the lateral aspect of the femur and the cortical strains were monitored while the patient performed a series of activities. In both patients, principle tensile strain increased significantly during one-legged stance, walking, and stair climbing as compared with that during two-legged stance. During each loading situation, the principal tensile strain was aligned within 22° to the longitudinal femoral axis. Dynamic strain measurements consistently revealed tensile axial strain at the lateral aspect of the femur during each activity. The present studv supports the classic bending theory of Pauwels and demonstrates that the proximal lateral aspect of the femur is subjected to tension during the stance phase of gait.     

Diffuse liver disease: MRI with Gd-DTPA versus CT and ultrasound

Twenty-nine patients with diffuse liver disease were examined by ultrasound, CT and MRI. MRI was performed using T1- and T2-weighted spin-echo sequences as well as fast gradient-echo-sequences. The paramagnetic contrast agent Gd-DTPA was applied intravenously (0.1 mmol/kg). in patients with hepatitis, MRI could be used in guiding liver biopsies as inflammatory changes were clearly delineated. CT and ultrasound were superior to MRI in the detection of focal or diffuse fatty degeneration. On the other hand MRI was more helpful in differentiating fatty changes and neoplasm. In liver cirrhosis, fibrotic changes were most clearly demonstrated by MRI. In patients suffering from hemochromatosis MRI offers advantages over CT and ultrasound in the diagnosis and follow up due to the paramagnetic properties of iron, resulting in a reduction in signal intensity. In patients with Wilson's disease a characteristic pattern of parenchymal changes was seen. Administration of Gd- DTPA contributes additional information about perfusion conditions in the liver parenchyma, however this information was not of diagnostic relevance in the cases we studied.

Solitary bronchioloalveolar carcinoma: CT criteria

The computed tomographic (CT) scans of 30 patients with solitary bronchioloalveolar carcinoma were reviewed. Common features at CT included the peripheral or subpleural location of a pulmonary mass (25 cases), pseudocavitation (18 cases), heterogeneous attenuation (17 cases), irregular margins forming a star pattern (22 cases), and pleural tags (21 cases). Using these CT criteria, four independent observers attempted to identify cases of bronchioloalveolar carcinoma from a larger sample of lung cancers and benign lesions by categorizing a series of test cases into four probability categories. Although the bronchioloalveolar carcinomas were correctly ranked in the two highest probability categories 75% of the time (in 45 of 60 cases), there was considerable overlap with other lung lesions, particularly with adenocarcinoma and large cell undifferentiated carcinoma. However, even though the typical features of bronchioloalveolar carcinoma are not invariable or highly specific, they are characteristic enough to suggest the diagnosis.     

Region-specific appearance of myelin constituents in the developing rat spinal cord

Summary The appearance of myelin-specific glycolipids and of myelin basic protein was studied with regard to the detailed anatomy of the rat cervical spinal cord. The expression of these constituents in particular fibre tracts and regions occurs at specific times of development between postnatal days 1 and 14. This mosaic-like appearance started in the ventral funiculus (day 1) followed by fasciculus cuneatus and ventro-lateral funiculus (day 2), and fasciculus gracilis and dorso-lateral funiculus (days 3 to 4). Cortico-spinal tract (day 11), Lissauer tract (day 14) and the commissures started to acquire myelin very late. In the grey matter, myelin constituents appeared around days 11 to 14 in a patchy pattern. These results support a concept of highly local interactions regulating oligodendrocyte differentiation. In addition, a general rostro-caudal gradient of myelin development exists in the spinal cord, which is independent of the ascending or descending nature of the fibre tracts. Appearance of myelin constitutents in the caudal spinal cord was not prevented by a neonatal transection at mid-thoracic levels.     

The PAR1 (YAP1/SNQ3) gene of Saccharomyces cerevisiae,ac-jun homologue,is involved in oxygen metabolism

Summary The PAR1/SNQ3 gene of S. cerevisiae, which increases resistance to iron chelators in multi-copy transformants, is identical to the YAP1 gene, a yeast activator protein isolated as a functional homologue of the human c-jun oncogene by binding specifically to the AP-1 consensus box. The observed H₂O₂-sensitivity of par1 mutants has been attributed to an increased sensitivity to reduced oxygen intermediates. Accordingly, par1 mutants did not survive an elevated oxygen pressure and were very sensitive to menadione and methylviologene, two chemicals enhancing the deleterious effects of oxygen. The specific activities of enzymes involved in oxygen detoxification, such as superoxide dismutase, glucose 6-phosphate dehydrogenase and glutathione reductase, were decreased in par1 mutants and increased after PAR1 over-expression. As in the case of oxygen detoxification enzymes, the cellular levels of glutathione were similarly affected. These observations indicate that PAR1/YAP1/SNQ3 is involved in the gene regulation of certain oxygen detoxification enzymes. The finding that H₂O₂ promotes DNA-binding of human c-jun is consistent with a similar function for PAR1/YAP1/SNQ3 and c-jun in cellular metabolism.Dedicated to Professor Dr. R. W.
