Biportal endoscopic paraspinal decompression for epidural cement leakage removal: A technical note.

OBJECTIVE: We aimed to preliminarily explore the efficacy and safety of unilateral biportal endoscopy (UBE) for the treatment of epidural cement leaks. We report a patient who underwent epidural cement leakage removal and achieved endoscopic spinal decompression. METHODS: A 67-year-old female patient underwent biportal endoscopic paraspinal decompression following percutaneous vertebroplasty for an osteoporotic fracture that resulted in neurologic impairment due to epidural cement leakage. A transforaminal biportal endoscopic surgery was performed to remove the leaked cement, and the left L1 and bilateral L2 nerves were decompressed. RESULTS: The patient's postoperative clinical course was uneventful. CONCLUSIONS: A paraspinal approach that avoids a posterior approach reduces the need to remove stabilizing facet bone, is truly minimally invasive and does not involve an instrumented fusion, maybe a helpful addition in the minimally invasive spine surgeon's armamentarium.

Case report: A complete lower cervical fracture dislocation without permanent neurological impairment.

BACKGROUND: Complete fractures and dislocations of the lower cervical spine are usually associated with severe spinal cord injury. However, a very small number of patients do not have severe spinal cord injury symptoms, patients with normal muscle strength or only partial nerve root symptoms, known as "lucky fracture dislocation". The diagnosis and treatment of such patients is very difficult. Recently, we successfully treated one such patient. CASE PRESENTATION: A 73-year-old male patient had multiple neck and body aches after trauma, but there was sensory movement in his limbs. However, preoperative cervical radiographs showed no significant abnormalities, and computed tomography (CT) and magnetic resonance imaging (MRI) confirmed complete fracture and dislocation of C7. Before operation, the halo frame was fixed traction, but the reduction was not successful. Finally, the fracture reduction and internal fixation were successfully performed by surgery. The postoperative pain of the patient was significantly relieved, and the sensory movement of the limbs was the same as before. Two years after surgery, the patient's left little finger and ulnar forearm shallow sensation recovered, and the right flexion muscle strength basically returned to normal. CONCLUSION: This case suggests that when patients with trauma are encountered in the clinic, they should be carefully examined, and the presence of cervical fracture and dislocation should not be ignored because of the absence of neurological symptoms or mild symptoms. In addition, positioning during handling and surgery should be particularly avoided to increase the risk of paralysis.

Comprehensive Insights into Metastasis-Associated Spinal Cord Compression: Pathophysiology, Diagnosis, Treatment, and Prognosis: A State-of-the-Art Systematic Review.

Background: Spinal cord compression is a formidable complication of advanced cancer, and clinicians of copious specialities often have to encounter significant complex challenges in terms of diagnosis, management, and prognosis. Metastatic lesions from cancer are a common cause of spinal cord compression, affecting a substantial portion of oncology patients, and only in the US has the percentage risen to 10%. Acute metastasis-correlated spinal cord compression poses a considerable clinical challenge, necessitating timely diagnosis and intervention to prevent neurological deficits. Clinical presentation is often non-specific, emphasizing the importance of thorough evaluation and appropriate differential diagnosis. Diagnostic workup involves various imaging modalities and laboratory studies to confirm the diagnosis and assess the extent of compression. Treatment strategies focus on pain management and preserving spinal cord function without significantly increasing patient life expectancy, while multidisciplinary approaches are often required for optimal outcomes. Prognosis depends on several factors, highlighting the importance of early intervention. We provide an up-to-date overview of acute spinal cord compression in metastases, accentuating the importance of comprehensive management strategies. Objectives: This paper extensively explores the pathophysiology, clinical presentation, diagnostic strategies, treatment modalities, and prognosis associated with spinal cord metastases. Materials and Methods: A systematic literature review was conducted in accordance with the PRISMA guidelines. Conclusions: We aim to help healthcare professionals make informed clinical decisions when treating patients with spinal cord metastases by synthesizing current evidence and clinical insights.

Perceptions of vision care following neurological impairment: a qualitative study.

BACKGROUND: Visual impairment is a common consequence of neurological impairments, and can impact a person's ability to undertake everyday tasks, affecting their confidence and mental health. Previous qualitative research in the UK has shown inequalities to exist where patients are accessing vision care after stroke, but little is known around the experiences of accessing vision care following other neurological impairments, and a lack of national guidelines prevent standardised care planning. The aim of this qualitative study is to explore the perceptions of vision care after neurological impairment, and to identify possible inequalities and support mechanisms, where it has been possible to access vision care. METHODS: University ethical approval was obtained, and adults with a visual impairment as a result of a neurological impairment were offered an in-depth interview to explore their vision care experiences. Data were collected between April and November 2021 and analysed using iterative, thematic analysis (TA), informed by a social constructionist ideology. RESULTS: Seventeen participants were recruited. Three overarching themes were conceptualised in relation to the participants' perception of vision care: Making sense of the visual impairment; The responsibility of vision care; and Influential factors in care quality perception. CONCLUSION: Inequalities were noted by participants, with most reporting a lack of suitable vision care offered as part of their neurological rehabilitation. Participants were thus burdened with the task of seeking their own support online, and encountered inaccurate and worrying information in the process. Participants noted changes in their identity, and the identity of their family carers, as they adjusted to their vision loss. The findings from this research highlight a need for clinicians to consider the long-term impact of vision loss after neurological impairment, and ensure patients are provided with adequate support and information, and appropriate referral pathways, alleviating this patient burden.

Virtual Reality-Based Interventions to Improve Balance in Patients with Traumatic Brain Injury: A Scoping Review.

INTRODUCTION: Virtual reality (VR)-based interventions to improve balance and mobility are gaining increasing traction across patient populations. VR-based interventions are believed to be more enjoyable and engaging for patients with traumatic brain injury. This scoping review aims to summarize existing studies from the literature that used VR to improve balance and mobility and determine the gap in VR-based balance literature specific to individuals with traumatic brain injury. METHODS: Two authors independently searched the literature using the search terms "Virtual Reality Traumatic Brain Injury Lower Limb", "Virtual Reality Traumatic Brain Injury Balance", and "Virtual Reality Traumatic Brain Injury Gait". RESULTS: A total of seventeen studies, specifically, three randomized controlled trials, one one-arm experimental study, two retrospective studies, two case studies, one feasibility/usability study, one cohort study, and seven diagnostic (validation) studies, met the inclusion criteria for this review. The methodological quality of the studies evaluated using the PEDro scale was fair. DISCUSSION: Future studies should focus on large-scale clinical trials using validated technology to determine its effectiveness and dose-response characteristics. Additionally, standard assessment tools need to be selected and utilized across interventional studies aimed at improving balance and mobility to help compare results between studies.

Stress Among Parents of Children With Severe Neurological Impairment in the Pediatric Intensive Care Unit.

Background: Children with severe neurological impairment (SNI) often receive care in the pediatric intensive care unit (PICU), yet little is known about their parents' experiences. Objective: To examine sources of and changes in stress among parents of children with SNI in the PICU. To compare stressors with "good parent" attributes that describe duties parents aim to uphold for their child. Design/Setting/Subjects: Prospective mixed-methods cohort study at a single U.S. children's hospital. Participants included English-speaking parents/legal guardians of a child with SNI with an expected length of stay >1 week and life expectancy >4 weeks. Measurements: Ten-point stress scale administered at PICU admission and discharge with open-ended response items. A subset of parents completed 1:1 semistructured interviews. Data were integrated to examine differences among participants whose stress increased, stayed the same, or decreased, and themes were compared with "good parent" attributes. Results: Twenty-five parents/legal guardians completed the surveys; 15 completed the interviews. Children were a median of 7 years old (interquartile range [IQR] 4, 9; range 1-21) and had a median PICU length of stay of 10 days (IQR 7, 15; range 3-62). Twenty percent (n = 5) of parents were fathers, and 36% (n = 9) had a minority racial/ethnic background. Stress was moderate at admission (mean 6.8, standard deviation [SD] ±1.7) and discharge (mean 6, SD ±2); 32% (n = 8) reported stress trajectories that stayed the same or increased. Major themes included uncertainty, advocacy, and vulnerability and related closely to "good parent" attributes. Conclusion: Stress among parents of children with SNI related to uncertainty, advocacy, and vulnerability and suggested tensions with "good parent" attributes.

Acute and Persistent Postoperative Functional Decline in Children with Severe Neurological Impairment: A Qualitative, Exploratory Study.

BACKGROUND: Children with severe neurologic impairment (SNI) regularly require major surgery to manage their underlying conditions. Anecdotal evidence suggests that children with SNI experience unexpected and persistent postoperative functional changes long after the postoperative recovery period; however, evidence from the perspective of caregivers is limited. The purpose of the study was to explore the functional postoperative recovery process for children with SNI. METHODS: Eligible participants were English-speaking caregivers of children with SNI between 6 months and 17 years who were nonverbal, Gross Motor Function Classification Scale level IV/V, and who had surgery/procedure requiring general anesthetic at a tertiary children's hospital between 2012 and 2022. Demographic and basic health information were collected via surveys and corroborated by a review of the child's electronic health record. Semi-structured interviews were conducted and a thematic content analysis was used to formulate results. RESULTS: Data from 12 primary caregiver interviews revealed four main themes: (1) functional changes and complications in the child; (2) feeling unprepared; (3) perioperative support; and (4) changes to caregiver roles. CONCLUSIONS: Postoperative functional decline in children with SNI was prevalent in our sample. Providing pre-operative information to families to describe this phenomenon should be a regular part of family-informed care.

Increased risk of complications in lower versus upper limb peripheral intravenous cannulation in children with severe neurological impairment.

BACKGROUND: Obtaining peripheral intravenous catheter (PIVC) access in children with severe neurological impairment (SNI) is often challenging and commonly associated with complications, including dislodgement, phlebitis and extravasation. In severe cases, extravasation injury may lead to tissue necrosis, ulceration and long-term morbidity. The aim of this study was to determine the relative incidence of PIVC complications secondary to lower limb cannulation, compared to upper limb, in children with SNI. METHODS: A single centre, retrospective, observational review was conducted. Patients with SNI, admitted at a tertiary paediatric centre over 6 months between July and December 2022, were included. RESULTS: One-hundred fifty-five PIVC procedures were conducted in 110 children over the study period. Complications were more common in lower limb PIVCs (12/16, 75%) compared to upper limb (58/139, 42%), p = 0.01. CONCLUSION: Upper limb cannulation is preferred in children with SNI.

The impact of low-energy, partially hydrolysed enteral formula on gastrointestinal symptoms and weight in children with neurological impairment: a multicentre retrospective study.

BACKGROUND: Neurological impairment (NI) relates to disorders of the central nervous system. The specific aetiology of NI varies but includes genetic, congenital abnormalities or brain injury. In children with severe NI, feeding impairments can lead to undernutrition, and some children require a feeding tube. Although tube feeding improves overall nutritional status, it has also been associated with excess body fat. Commercially available enteral formulas that are low in energy, hydrolysed and nutritionally adequate for protein and micronutrients are available to mitigate gastrointestinal symptoms and obesity. METHODS: This is a retrospective multicentre study of children who attended NI clinics between January 2022 and July 2023. Data were collected before and 1 month after receiving a low-energy, partially hydrolysed enteral formula (0.6 kcal/mL) on demographic data (age, sex, ethnicity and NI diagnosis), anthropometric measurements (weight, height, weight-for-age Z-score, height-for-age Z-score, body mass index [BMI] Z-score) and feed regimen (feed volume, total fluids and type of formula/supplements). RESULTS: Dietitians collected data on 28 children, the median age was 7 years (interquartile range [IQR] 3, 8). The most frequently recorded NI was cerebral palsy, in 13 of 28 children (48%). Before the formula switch, the most frequently reported gastrointestinal symptom was constipation, in 13 of 28 children. Within 1 month of switching to a low-energy, hydrolysed formula, 10 of the 13 (77%) children reported an improvement in constipation. Before the formula switch, all 28 children were experiencing excessive weight gain. After the formula was switched to low-energy, hydrolysed formula, dietitians reported that 20 of the 28 (76%) children's weight either stabilised or reduced after 1 month. There was no statistically significant difference in weight-for-age Z-score or BMI Z-scores postswitch of formula (p-value 0.1 and 0.09, respectively). Fibre intake increased significantly from 3.3 to 8.1 g/day (p-value < 0.01) after formula switch. The number of children whose feed regimens were simplified after switching to a low-energy, partially hydrolysed formula was 24 of 28 (91%). CONCLUSIONS: Children with an NI who have gastrointestinal symptoms may benefit from a low-energy, hydrolysed enteral formula to maximise feed tolerance and promote healthy weight gain. In addition, changing to a low-energy, hydrolysed formula may simplify feed regimens by eliminating the need for additional electrolytes, multivitamins and fluid boluses. Healthcare professionals should be knowledgeable about the effectiveness and availability of a low-energy, hydrolysed formula.

Nrdp1-mediated Macrophage Phenotypic Regulation Promotes Functional Recovery in Mice with Mild Neurological Impairment after Intracerebral Hemorrhage.

Neuregulin receptor degradation protein 1 (Nrdp1) is a ring finger E3 ubiquitin ligase involved in some inflammation through ubiquitination, including macrophage polarization following cerebral hemorrhage. However, there is limited understanding regarding the mechanisms through which Nrdp1 modulates macrophage polarization and the potential impact of this modulation on neurological function. Using stereotactic injection and adenoviral transfection techniques, the corresponding animal models were constructed through injecting adenovirus, saline, or blood into the mouse striatum at different periods of time in this research. The alteration in the ratio of various M1/M2 phenotype-associated markers (e.g., CD86, CD206, IL-6, IL-10, etc.) was evaluated through immunohistochemistry, immunofluorescence, western blotting, and elisa assays. Additionally, neurological function scores and behavioral tests were utilized to evaluate changes in neurological function in mice after cerebral hemorrhage. Our results show that overexpression of Nrdp1 promotes the expression of a variety of M2 macrophage-associated markers and enhance transcriptional activity of arginase-1 (Arg1) protein through ubiquitination for early regulation M2 macrophage polarization. Additionally, Nrdp1 promotes hematoma absorption, increases IL-10 expression, inhibits inducible nitric oxide synthase (iNOS), IL-6, and TNF-α production, alleviates neurological impairment and brain edema, and accelerates functional recovery. These findings suggest that modulating macrophage polarization through Nrdp1 could be a therapeutic strategy for neurofunctional impairment in cerebral hemorrhage.

The Evaluation of Gastric Emptying Using the 13 C-Acetate Breath Test in Neurologically Impaired Patients - A Focus on the Stomach Function and Morphology.

PURPOSE: We explored factors affecting gastric emptying in neurologically impaired (NI) patients using the 13C-acetate breath test. METHODS: Twenty-four NI patients were classified by the presence of gastroesophageal reflux disease (GERD), which was treated by fundoplication plus gastrostomy, or the absence of GERD, which was treated by gastrostomy alone, along with gastric malposition involving cascade stomach and organoaxial gastric volvulus (OGV). Gastric emptying parameters (GEPs), which were the emptying half time (T 1/2 , minute), the lag phase time (T lag , minute), and the gastric emptying coefficient (GEC), were measured before and after surgery. We evaluated the relationship between GEPs and GERD, gastric malposition, and surgical intervention. All data were expressed as the median (interquartile range). RESULTS: The T1/2 and GEC of patients with OGV were significantly worse than in those without OGV before surgery (T1/2 with OGV: 241.3 [154.9, 314.3] vs. T1/2 without OGV: 113.7 [105.2, 151.4], p = 0.01, GEC with OGV: 3.19 [2.46, 3.28] vs. GEC without OGV: 3.65 [3.24, 3.90], p = 0.02). GERD and cascade stomach were not associ ated with GEPs. The GEPs of all NI patients showed no significant difference between before and after surgery. The surgical change in T1/2 (ΔT 1/2 ) in the patients with OGV was significantly lower than in those without OGV (ΔT1/2 with OGV: -47.1 [-142.7, -22.1] vs. ΔT1/2 without OGV: -3.78 [-26.6, 12.0], p = 0.03). CONCLUSION: Stomach malposition, such as OGV, seems to affect gastric emptying and may be improved by surgi cal intervention.

Impact of metastatic epidural spinal cord compression (MESCC) and pathological vertebral compression fracture (pVCF) in neurological and survival prognosis.

BACKGROUND: Metastatic epidural spinal cord compression (MESCC) and pathological vertebral compression fractures (pVCF) are the most serious debilitating morbidities of spine metastases (SpMs) causing devastating neurological damages. The respective impact of these two metastasis-spreading entities on survival and on neurological damage is debated. METHODS: A French prospective cohort study collected 279 consecutive patients presenting with SpMs between January 2017 and 2021. We compared 174 patients with MESCC and 105 patients with pVCF. RESULTS: The median Overall Survival (OS) for the MESCC group was 13.4 months (SD 1.5) vs 19.2 months (SD 2.3) for pVCF patients (p = 0.085). Sixty-five patients (23.3 %) were operated on: 49/65 (75.4 %) in the MESCC group and 16/65 (15.2 %) in the pVCF group, p < 0.0001. At 6 months FU, in the MESCC group, 21/44 (45.4 %) of non-ambulatory patients at onset improved to ambulatory status (Frankel D-E) vs 10/13 (76.9 %) in the pVCF group (p = 0.007). In multivariable analysis with the Cox proportional hazard model, good ECOG-PS and SINS Score 7-12 [HR: 6.755, 95 % CI 2.40-19.00; p = 0.001] were good prognostic factors for preserved ambulatory neurological status. However, SpMs diagnosed synchronously with the primary tumor [HR: 0.397, 95 % CI 0.185-0.853; p = 0.018] and MESCC [HR: 0.058, 95 % CI 0.107-0.456; p = 0.007] were independent risk factors for impaired neurological function. CONCLUSION: Contrary to pVCF, MESCC causes neurological damage. Nevertheless, neurological recovery remains possible. MESCC and pVCF have no impact on survival. The management of MESCC remains to be clarified and optimized to reduce neurological damage.

Clinical recommendations for the inpatient management of lower respiratory tract infections in children and adolescents with severe neurological impairment in Germany.

Children and adolescents with severe neurological impairment (SNI) require specialized care due to their complex medical needs. In particular, these patients are often affected by severe and recurrent lower respiratory tract infections (LRTIs). These infections, including viral and bacterial etiology, pose a significant risk to these patients, often resulting in respiratory insufficiency and long-term impairments. Using expert consensus, we developed clinical recommendations on the management of LRTIs in children and adolescents with SNI. These recommendations emphasize comprehensive multidisciplinary care and antibiotic stewardship. Initial treatment should involve symptomatic care, including hydration, antipyretics, oxygen therapy, and respiratory support. In bacterial LRTIs, antibiotic therapy is initiated based on the severity of the infection, with aminopenicillin plus a beta-lactamase inhibitor recommended for community-acquired LRTIs and piperacillin-tazobactam for patients with chronic lung disease or tracheostomy. Ongoing management includes regular evaluations, adjustments to antibiotic therapy based on pathogen identification, and optimization of supportive care. Implementation of these recommendations aims to improve the diagnosis and treatment of LRTIs in children and adolescents with SNI. What is Known: • Children and adolescents with severe neurological impairment are particularly affected by severe and recurrent lower respiratory tract infections (LRTIs). • The indication and choice of antibiotic therapy for bacterial LRTI is often difficult because there are no evidence-based treatment recommendations for this heterogeneous but vulnerable patient population; the frequent overuse of broad-spectrum or reserve antibiotics in this patient population increases selection pressure for multidrug-resistant pathogens. What is New: • The proposed recommendations provide a crucial framework for focused diagnostics and treatment of LRTIs in children and adolescents with severe neurological impairment. • Along with recommendations for comprehensive and multidisciplinary therapy and antibiotic stewardship, ethical and palliative care aspects are taken into account.

Malnutrition in Institutionalized and Non-Institutionalized Neurologically Impaired Children in Bulgaria.

INTRODUCTION: The nutritional status of children with neurological impairment affects their health and quality of life. Bulgaria has many abandoned disabled children in residential homes. Lack of parental care puts them at risk for poor growth, suboptimal nutrition, and physical and mental development. Our study aims to identify factors associated with poor nutrition in Bulgarian children with neurological impairment living in different environments. METHODS: From January to December 2017, a cross-sectional study was conducted in northeastern Bulgaria. We recruited 109 residential and nonresidential children. The study included demographics, medical history, anthropometric measurements, biochemical tests, nutritional assessment, and gastrointestinal signs and symptoms. Data were analyzed with Jamovi 2.2.5 at a 0.05 significance level. Logistic regression was used to predict wasting in both environmental settings. RESULTS: About 70% of the neurologically impaired children living in residential settings have malnutrition based on weight-for-age Z-score, compared to 25% of the non-residential children. Prematurity, low gross motor function (as measured by the gross motor function classification system), pureed food consumption, birth before 37 weeks, and living in residential care homes are linked to poor nutrition. CONCLUSION: Neurologically impaired children have a poor nutritional state, especially those living in residential homes. The study underscores the pressing need for the allocation of additional nutrition resources to effectively address the nutritional and developmental needs of children with neurological disabilities in Bulgaria.

Increased muscle responses to balance perturbations in children with cerebral palsy can be explained by increased sensitivity to center of mass movement.

BACKGROUND: Balance impairments are common in children with cerebral palsy (CP). Muscle activity during perturbed standing is higher in children with CP than in typically developing (TD) children, but we know surprisingly little about how sensorimotor processes for balance control are altered in CP. Sensorimotor processing refers to how the nervous system translates incoming sensory information about body motion into motor commands to activate muscles. In healthy adults, muscle activity in response to backward support-surface translations during standing can be reconstructed by center of mass (CoM) feedback, i.e., by a linear combination of delayed (due to neural transmission times) CoM displacement, velocity, and acceleration. The level of muscle activity in relation to changes in CoM kinematics, i.e., the feedback gains, provides a metric of the sensitivity of the muscle response to CoM perturbations. RESEARCH QUESTION: Can CoM feedback explain reactive muscle activity in children with CP, yet with higher feedback gains than in TD children? METHODS: We perturbed standing balance by backward support-surface translations of different magnitudes in 20 children with CP and 20 age-matched TD children and investigated CoM feedback pathways underlying reactive muscle activity in the triceps surae and tibialis anterior. RESULTS: Reactive muscle activity could be reconstructed by delayed feedback of CoM kinematics and hence similar sensorimotor pathways might underlie balance control in children with CP and TD children. However, sensitivities of both agonistic and antagonistic muscle activity to CoM displacement and velocity were higher in children with CP than in TD children. The increased sensitivity of balance correcting responses to CoM movement might explain the stiffer kinematic response, i.e., smaller CoM movement, observed in children with CP. SIGNIFICANCE: The sensorimotor model used here provided unique insights into how CP affects neural processing underlying balance control. Sensorimotor sensitivities might be a useful metric to diagnose balance impairments.

Components of Oral Health Related to Motor Impairment in Children With Neuropsychiatric Disorders.

Introduction Oral health significantly influences functions such as chewing, swallowing, and overall well-being. Children with neuropsychiatric disorders (NPD) often experience compromised oral functions, escalating their risk of malnutrition. Materials and methods Our study, conducted in Varna, Bulgaria, from April to October 2017, aimed to evaluate some components of the oral health of 49 children with NPD and its relation to their motor impairments. In the studied cohort, participants were categorized based on their Gross Motor Function Classification System (GMFCS) scores into two groups: minor limitations (ML), encompassing GMFCS levels 1-3, and gross limitations (GL), which included GMFCS levels 4-5. Comprehensive oral examinations were conducted by a trained dentist. Data analysis utilized the JAMOVI v.2.2.2.0 software with a 0.05 significance threshold. Results Preliminary findings indicate that children with more pronounced motor limitations have poorer oral health compared to their mildly impaired counterparts. A mere 14.3% (n=7) of the children with NPD had recorded dental visits. The data show that 18.2% (n=6) of ML children had at least an annual dental consultation, while only a single child (6.2%) from the GL group had a dental visit, leaving a staggering 93.8% (n=15) without any. Statistical analyses indicate a significant relationship between motor activity (MA) and toothbrushing frequency (r=0.529, p=0.0001), suggesting that children with better MA have improved chances of maintaining oral hygiene. A significant correlation was observed between dental visits and toothbrushing frequency (r=0.371, p=0.0007). Conclusion Given their challenges, children with NPD require increased attention to dental care, emphasizing regular checkups and preventive oral health measures. This study prompts a reevaluation of these care standards.

Navigating Stress in the Pediatric Intensive Care Unit Among Parents of Children with Severe Neurological Impairment.

CONTEXT: Children with severe neurological impairment (SNI) make up nearly 50% of pediatric intensive care unit (PICU) admissions, yet little is known about their family caregiver experiences. OBJECTIVE: To examine how parents and family caregivers of children with SNI navigate stress during PICU admissions. METHODS: This qualitative single-center study used content and thematic networks analysis to evaluate data from 1:1 semistructured interviews conducted around the time of PICU discharge with parents and family caregivers of children with SNI to examine ways they navigate stress. Proportions of participants reporting each theme and subtheme were calculated. RESULTS: Fifteen parents/family caregivers of 15 children with SNI participated. Children were a median of 8 years old (range 1-21 years) and the majority had congenital/chromosomal conditions leading to their neurologic condition (80%, n = 12). 20% of participants were fathers (n = 3) and 45% (n = 7) reported identifying as having a minority racial background. Themes included 1) self-activation, and 2) letting go and the majority (80%, n = 12) of parents reported using both self-activation and letting go strategies. Within each of these themes, 5 subthemes illustrated ways parents navigate stress. The most reported subthemes were advocating and showing up (53%, n = 8) and being supported by compassionate clinicians (67%, n = 10). Themes/subthemes were used to create recommended language to guide clinicians in supporting parents. CONCLUSION: Parents and family caregivers of children with SNI employ various ways to navigate stress in the PICU. Themes from this study can be used to develop interventions that meet the psychosocial needs of parents and family caregivers of children with SNI during highly stressful times.

Aucubin promotes activation of AMPK and alleviates cerebral ischemia/reperfusion injury in rats.

In the current investigation, we explored the benefits of aucubin against rodent ischemia/reperfusion (I/R) damages in brains and elucidated the role of 5'-AMP-activated protein kinase (AMPK) in its neuroprotective action. I/R model of brain was established in male three-month-old rats through 2 h of middle cerebral artery occlusion followed by two days of reperfusion. Aucubin boosted phosphorylation of AMPKα in ipsilateral cortex of injured rats. Then, rats were exposed to cerebral I/R damage and received treatment of aucubin and compound C (a well-known AMPK inhibitor). It was found that aucubin administration improved neurological symptom score, decreased infarct volume, and mitigated cerebral edema in injured rats. Aucubin administration upregulated Nrf2 expression and abated oxidative stress in ipsilateral cortex of injured rats. Aucubin administration reduced levels of multiple pro-inflammatory cytokines, suppressed microglial activation and neutrophil infiltration, and promoted M2 polarization in injured rats. More importantly, compound C abolished the neuroprotective, anti-oxidant and inflammation-modulating effects of aucubin in injured rats, at least in part. Therefore, we concluded that activation of AMPK by aucubin alleviated I/R injury in brain through abating oxidative stress and suppressing inflammation, identifying a potential candidate for those patients of ischemic stroke.
