Illness representation in patients with multiple sclerosis: A preliminary narrative medicine study.

Background: The development of personalized interventions aimed at coping with multiple sclerosis is enriched by the understanding of patients' representations of the illness. Objective: The aim of this study was to investigate the association between patients' illness representations versus contextual factors (i.e. presence/absence and type of caregiver, engagement, frequency and type of rehabilitation), fatigue, pain, and neurological impairment. Methods: Interviews of 28 patients were analysed through an automated text analysis procedure. After a systematic labelling procedure four illness representations were identified: daily life, search for meaning of the disease, relationship to people and the diagnosis, coping and physical growth. Results: Findings showed that the representation of the relational aspects of the illness was associated with the caregiver's presence, while the representation related to coping and growth tended to be associated with participation in rehabilitation programs. Moreover, the representation related to daily life was associated with lower levels of fatigue compared to the representation related to coping and growth, and with higher levels of neurological impairment compared to the representations related to coping and growth and the relational aspects of the illness. Conclusion: Exploring illness representations is a key step that can help health professionals to get an integrated perspective that could be useful in designing and calibrating interventions according to specific patient needs.

The management of Pseudomonas aeruginosa respiratory infection in children with cerebral palsy: A narrative review.

Children with cerebral palsy have increased respiratory morbidity and mortality. Infection with Pseudomonas aeruginosa (PA) is associated with poorer outcomes, yet there are no formal guidelines to inform treatment of respiratory infection in children with cerebral palsy. This review explores the existing literature regarding management of PA-infection in children with cerebral palsy, with the aim of synthesising clinical recommendations and identifying gaps in current understanding. Medline (Ovid), PubMed and Embase were searched using keywords. Full-text articles involving the paediatric population and antimicrobial therapy were included. There was no limit on date of publication. Four retrospective case series were identified. Respiratory microbiology, in samples collected from a range of sites along the respiratory tract, was reported in three studies. Patients who received PA-specific antibiotics clinically improved. Two studies suggest that the use of suppressive inhaled anti-pseudomonal therapy may improve respiratory morbidity in the chronic setting. There is minimal evidence to guide management of PA respiratory infection in children with cerebral palsy. Children with cerebral palsy are at risk of developing bronchiectasis, so in the absence of high-quality evidence, management should be informed by extrapolating from the non-cystic fibrosis bronchiectasis guidelines. Further research examining surveillance and management of PA-infection in this population is required given that early intervention may prevent irreversible lung damage.

Clinical characteristics, treatment and prognosis of children with SARS-CoV-2 infection complicated with severe neurological dysfunctions in Foshan, China.

Objective: To analyze the clinical characteristics, treatment, and prognosis of children infected with SARS-CoV-2 following the adjustment of COVID-19 prevention and control policies in China in December 2022. Methods: A retrospective study was conducted on 9 cases of severe neurological dysfunction caused by SARS-CoV-2 infection in children admitted to Foshan First People's Hospital from December 17 to 31, 2022. Results: Among the 9 cases, 7 (71.43%) were under 3 years old, and 2 (22.2%) were over 3 years old with underlying diseases. All patients presented with fever and neurological symptoms such as consciousness disturbance and/or convulsions, and their conditions deteriorated rapidly within 24 h after the onset of fever, without respiratory symptoms. Levels of IL-6, LDH, and d-dimer were significantly elevated. Five cases died within 48 h of admission, one case died after 7 days of treatment due to secondary bacterial infection, and three cases survived for more than 48 h after the initial rescue. All patients developed rapid shock, and five cases experienced multi-organ failure within a short period. In terms of treatment, glucocorticoids were used in 5 cases, intravenous immunoglobulin (IVIG) in 3 cases, and blood purification and tocilizumab in 2 cases. Conclusion: SARS-CoV-2 infection in children can lead to severe neurological damage. High fever, convulsions, and inflammatory factors serve as early warning indicators. Glucocorticoids, immunoglobulins, blood purification, and tocilizumab may have some therapeutic effects, but further research is needed to confirm the efficacy.

Telemedicine in nutritional management of children with severe neurological impairment: implication for quality of life.

Children with severe neurological impairment (SNI) frequently present feeding problems requiring a close monitoring of their nutritional status. In addition to constant clinical monitoring of body composition and nutritional indexes in these patients, frequent reports of dietary intake and weight gain variations are useful to ensure proper nutritional management. Furthermore, non-oral feeding is often needed to avoid malnutrition or aspiration pneumonia, constantly necessitating medical assistance. Despite their necessity for frequent hospital accesses, these patients' disabilities represent an important obstacle to accessing care, generating anxiety and concern in children and their families. Telemedicine has proven to be a promising instrument for improving pediatric patients' healthcare in several fields. By breaking down geographical and temporal barriers, telehealth may represent a valuable tool to implement in clinical practice, in order to improve patients' outcomes and quality of life. The aim of this narrative review is to provide an overview of the main nutritional issues in children with SNI, the potential implications of telemedicine in their management and the available evidence regarding the effects and benefits of telehealth.

Exploring the hidden mental health consequences of malaria beyond the fever.

Malaria morbidity has various presentations and the focus now shifts to uncommon signs and symptoms of malaria infection such as cognitive impairment to address the morbidity when the mortality declines. About 50% of children admitted to hospitals due to malaria experience neurological complications due to factors like low blood sugar, inflammation, elevated pressure, decreased oxygen levels, and excitotoxicity. Malaria during pregnancy negatively also impacts children's cognitive, behavioral, and executive function leading to neurodevelopmental delay due to increased susceptibility which can significantly affect maternal and child health, leading to higher rates of underestimated factors like anxiety, depression, and PTSD. Despite having the world's second-largest tribal population, India's indigenous and tribal communities and their mental health are less explored and less understood. Western psychological tools and neurocognitive assessment tools are not universally applicable, thus necessitating the development of tailored tools to investigate psychological or neurocognitive impairment. This paper has illuminated the hidden mental health consequences of malaria infection, emphasizing the prevalence, nature, and implications of psychological distress among affected individuals. The findings underscore the importance of recognizing and addressing these psychological consequences in the holistic management and prevention of malaria and its mental health consequences.

The Power of Movement: A Comprehensive Case Study of Physiotherapeutic Approaches in Electrical Injury Rehabilitation.

Electrical injuries are common phenomena in developing countries, due to inadequate safety measures followed during day-to-day electrical repairs. Workplace injuries account for 20% of these. In some severe cases, electrical injuries lead to burns, indirect fracture dislocations, speech impairments, etc. Falls due to electrical injuries leading to secondary complications are very common and, even though not very severe, they do require immediate treatment and adequate rehabilitation. A 53-year-old male suffered a shoulder injury following an electrical shock. The patient also experienced irritation and speech disturbances. Examination revealed a reduced range of shoulder joints and tightness of muscles of the shoulder complex. Physiotherapy intervention included counseling for the patient and his family members, energy conservation methods for ease in daily activities, a rehabilitation protocol, and modified music therapy. Outcome measures used to assess the progression constituted the Shoulder Pain and Disability Index (SPADI), the Tampa Scale for Kinesiophobia (TSK), and the Depression and Anxiety and Stress Scale. Rehabilitation with adjunct therapy is effective in the overall improvement of the patient's condition concerning their mental health as well as physical health by early strength training.

Cerebral involvement in sitosterolemia.

BACKGROUND: Sitosterolemia, an autosomal recessive condition, is characterized by impaired metabolism of plant sterols. Clinical symptoms include skin xanthoma, premature atherosclerotic disease, arthritis, and unexplained hematological abnormalities. However, there is a dearth of studies on sitosterolemia-related brain damage. METHODS: This study focused on the family of two sitosterolemia patients who presented with severe hypercholesterolemia and xanthoma. Radiological examinations, biopsies, whole-exome sequencing (WES), and plant sterol tests were conducted. RESULTS: The index patient, a 66-year-old female, initially exhibited weakness in both lower limbs and later developed urinary and fecal incontinence. Neuroimaging showed that the falx of the brain had irregular fusiform thickening. Significant tissue edema was observed around the lesions in the bilateral frontal-parietal lobes. Pathological analysis of the biopsied brain lesion revealed extensive cholesterol crystal deposition and lymphocyte infiltration in the matrix. The index patient who experienced cerebral impairment and her sister both carried two compound heterozygous variants in ATP binding cassette transporter G5 (ABCG5). These included the nonsense variants NM_022436: c.751 C > T (p.Q251X) in exon 6 and NM_022436: c.1336 C > T (p.R446X) in exon 10. A notable increase in plant sterol levels was observed in the younger sister of the index patient. CONCLUSION: This study highlights a previously unreported neurological aspect of sitosterolemia. Imaging and pathology findings suggest that cholesterol crystals may be deposited in connective tissues such as the cerebral falx and pia mater through blood circulation.

Ischemic perfusion radiomics: assessing neurological impairment in acute ischemic stroke.

Introduction: Accurate neurological impairment assessment is crucial for the clinical treatment and prognosis of patients with acute ischemic stroke (AIS). However, the original perfusion parameters lack the deep information for characterizing neurological impairment, leading to difficulty in accurate assessment. Given the advantages of radiomics technology in feature representation, this technology should provide more information for characterizing neurological impairment. Therefore, with its rigorous methodology, this study offers practical implications for clinical diagnosis by exploring the role of ischemic perfusion radiomics features in assessing the degree of neurological impairment. Methods: This study employs a meticulous methodology, starting with generating perfusion parameter maps through Dynamic Susceptibility Contrast-Perfusion Weighted Imaging (DSC-PWI) and determining ischemic regions based on these maps and a set threshold. Radiomics features are then extracted from the ischemic regions, and the t-test and least absolute shrinkage and selection operator (Lasso) algorithms are used to select the relevant features. Finally, the selected radiomics features and machine learning techniques are used to assess the degree of neurological impairment in AIS patients. Results: The results show that the proposed method outperforms the original perfusion parameters, radiomics features of the infarct and hypoxic regions, and their combinations, achieving an accuracy of 0.926, sensitivity of 0.923, specificity of 0.929, PPV of 0.923, NPV of 0.929, and AUC of 0.923, respectively. Conclusion: The proposed method effectively assesses the degree of neurological impairment in AIS patients, providing an objective auxiliary assessment tool for clinical diagnosis.

Prevalence and correlates of cognitive impairment among an urban geriatric population of Haryana.

Background: Severe Cognitive Impairment (CI) is a major cause of disability and dependency among the elderly worldwide, and it has a significant impact not only on individuals but also on families, communities, and societies. Early identification and management of CI are critical in geriatric medicine. Prevalence data is often scarce, and this hinders the ground-level implementation of preventive health programs. Objectives: The objective was to find the prevalence of CI and its covariates among the urban geriatric population of Haryana. Materials and Methods: This was a community-based cross-sectional study conducted among 300 geriatric participants residing in an urban area of Rohtak district, Haryana. Hindi Mental State Examination (HMSE) tool was used to assess CI. Data were analyzed using IBM Corp, released 2020, IBM SPSS statistics for windows Ver 20, Armonk, NY. Results: The prevalence of geriatric CI was found to be 27.3% and was found to be significantly associated with age, female gender, scheduled and backward caste (BC), widowhood, and low educational status and is not engaged in any occupation, low socioeconomic status, teetotalism, economic dependency, physical dependency on others, and chronic morbidity. Conclusion: Age, female gender, scheduled and backward caste, widowhood, low educational status, nil employment status, low socioeconomic status, teetotalism, economic dependency, physical dependency on others, and chronic morbidity were found to be important correlates of CI. Further analytical studies can focus on these aspects for an early targeted preventive approach.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
