INTRODUCTION
Hepcidin is a peptide associated with controlling the distribution of iron in tissues. Growing interest is linked with its impact on neurodegenerative diseases, as disruption of the iron regulation may be considered an initiatory element of pathological protein accumulation. The possible impact of hepcidin was not previously sufficiently explored in progressive supranuclear palsy (PSP).
METHODS
Twelve patients with PSP-Richardson's syndrome (PSP-RS), 12 with PSP-Parkinsonism Predominant (PSP-P), and 12 controls were examined using Unified Parkinson's Disease Rating Scale-III part (UPDRS-III) in OFF stage and analyzed in the context of hepcidin levels in the serum.
RESULTS
The work revealed increased levels of hepcidin in PSP-RS when compared to PSP-P and controls. Moreover, hepcidin was found to be negatively correlated with UPDRS-III results in PSP-RS, whereas positively in PSP-P.
CONCLUSION
The work may suggest a possible impact of hepcidin in PSP, possibly differing depending on its subtype.

Retroclival hematomas are a rare entity, presenting anteriorly to the brainstem in the epidural, subdural, or subarachnoid space. Although those that develop in the epidural space often arise from trauma, subdural retroclival hematomas frequently occur spontaneously in the setting of coagulopathy, aneurysm rupture, or pituitary apoplexy, with many cases having an unknown etiology.1-4 Although most are treated with conservative management, surgical intervention is preferred for those presenting with evidence of brainstem compression, hydrocephalus, worsening neurological deficits, and clinical deterioration.5 In this report, we present the case of a 75-year-old woman with a medical history of mitral regurgitation, nonischemic cardiomyopathy, and atrial fibrillation on warfarin presenting with 4 days of temporoparietal headaches and double vision. On examination, the patient demonstrated right abducens and hypoglossal nerve palsies. Computed tomography revealed a subdural hemorrhage within the retroclival cistern, extending into the dorsal inferior aspect of the C2 vertebral body, resulting in posterior displacement of the pons, medulla, and proximal cervical spinal cord. Spinal and cerebral angiograms did not show evidence of any vascular malformation. An endoscopic transclival approach was selected for hematoma evacuation. Key surgical steps included harvesting of nasoseptal flap, endoscopic transnasal approach to the sellar/subsellar space, transclival drilling, retroclival hematoma evacuation, and clival reconstruction. The patient tolerated the procedure well and was discharged 15 days postoperatively with resolution of prior cranial nerve deficits. Postoperative computed tomography imaging revealed complete retroclival hematoma evacuation. At her 3-month follow-up, the patient remained neurologically intact with imaging confirming no residual subdural hematoma. Institutional Review Board approval was obtained for this submission (2018-9379). Patient consent was not obtained as personal identifying information was kept confidential, following guidelines set forth by Institutional Review Board requirements.

OBJECTIVE
Injection laryngoplasty (IL) with hyaluronic acid (HA) is an effective treatment for patients with glottic insufficiency. The duration of HA maintenance in the vocal fold remains unknown. In this study, transcutaneous laryngeal ultrasound (TLUS) was used to evaluate the absorption and migration of HA after IL. Subsequent management might be provided based on the TLUS finding.
METHODS
Patients diagnosed with unilateral vocal fold paralysis (UVFP) or vocal fold atrophy were recruited. All patients underwent IL with HA in an office-based setting along with TLUS to monitor the status of HA. The schedule of TLUS included assessments before and after IL until non-visualization.
RESULTS
The study population comprised 38 women and 17 men. Of the patients, 54.1% underwent IL for UVFP, whereas 45.9% underwent IL for vocal fold atrophy. Multivariate Cox regression analysis for factors affecting HA absorption revealed that the cause of injection was the most important independent predictor (hazard ratio [HR], 2.15; 95% confidence interval [CI], 1.03-4.46; p = 0.040). The duration of HA maintenance was significantly longer in patients with UVFP than in those with vocal fold atrophy (8.77 vs. 4.70 months, HR, 2.33; 95% CI, 5.47-8.18; p = 0.002).
CONCLUSION
TLUS is an objective assessment method for patients undergoing IL with HA. Subsequent tailor-made management could be offered based on the TLUS findings during follow-up. For patients at high risk of upper respiratory tract infection or who are intolerant to flexible nasopharyngoscopy, TLUS can be used as an alternative tool to evaluate the condition of the glottis after IL with HA.

Review
The effectiveness of exergames in improving physical activity behaviour and physical literacy domains in adolescents with developmental coordination disorder and cerebral palsy: A scoping review.
BACKGROUND
A large proportion of adolescents with developmental coordination disorder (DCD) are physically inactive. Physical literacy has been described as an important determinant in promoting health behaviours. The potential of exergames to improve physical literacy and activity has been recognized in typically developing children. The aim of the present scoping review was to identify and map the available evidence of this potential for adolescents with DCD.
METHODS
A scoping review was performed via a literature search in PubMed, Web of Science, Embase, ERIC and CINHAIL.
RESULTS
From 2860 search records, six studies (two studies in DCD and four studies in cerebral palsy [CP]) assessed physical activity, 12 studies discussed exergame features and 16 studies assessed physical literacy domains. In DCD, one study showed positive effects of exergaming on physical activity and the other failed to show any significant effects of exergaming. In CP, all four studies demonstrated positive effects of exergaming on energy expenditure and daily physical activity. Furthermore, positive effects of exergames on the different physical literacy domains were shown, namely motor competence, self-concept and affect, motivation and social/experiential. Finally, exergame features including multiplayer modes, realism, game rewards, challenges and enjoyment were shown to have a significant effect on motivating and encouraging adolescents to exert more effort while playing.
CONCLUSION
Based on the positive effects of exergaming on physical activity in other populations, more in-depth research in adolescents with DCD is warranted such that the decline in physical activity behaviour that is present in individuals with DCD can be counteracted. Physical literacy should be regarded as an important determinant in this regard.

Review
OBJECTIVE
Arnold-Chiari Malformation is one possible cause of congenital vocal cord paralysis (VCP). The natural history of VCP in children with Chiari malformation has previously been limited to small case studies. This systematic review seeks to better characterize the prognostic factors that may predict symptom severity and resolution of congenital VCP in children with Arnold-Chiari malformation. We hypothesized that the onset of stridor or VCP at a younger age would be associated with a poorer prognosis and earlier intervention with posterior fossa decompression would be associated with better outcomes.
DATA SOURCES
PubMed, Web of Science, Cochrane Library, and bibliographic review.
REVIEW METHODS
A systematic review was performed according to Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Database search yielded 866 articles. Study abstracts were reviewed by 2 independent examiners. One hundred and seventy-six studies underwent full-text review. The following were extracted: age at onset of stridor or VCP, Chiari malformation type, laryngoscopy findings, type and timing of neurosurgical intervention, and tracheostomy history. Statistical analyses utilized χ tests.
RESULTS
Younger age at symptom onset showed statistically significant associations with decreased likelihood for symptom resolution and tracheostomy decannulation. The shorter time interval from symptom onset to neurosurgical intervention was not significantly associated with better outcomes.
CONCLUSION
This meta-analysis suggests poorer prognosis in those with earlier-onset symptoms, reinforcing prior case series findings. Additional prospective studies are needed to elucidate the natural history and utility of early intervention in children with vocal cord paralysis secondary to Chiari malformation.

Meige syndrome, a rare form of cranial dystonia, manifests as involuntary spasms affecting the facial and neck muscles. Diagnosing Meige syndrome is challenging due to its similarities with various movement disorders and psychiatric conditions. Functional neurological disorder (FND) refers to a condition characterized by neurological symptoms that are inconsistent with recognized neurological or medical conditions. Symptoms may include motor or sensory disturbances such as weakness, tremors, paralysis, or seizures. Importantly, these symptoms cannot be fully explained by another medical condition or by the direct effects of a substance. Instead, they are believed to stem from psychological factors. This case demonstrates the diagnostic dilemma of Meige syndrome. It was initially misdiagnosed as a functional neurological disorder in a 42-year-old female. The difficulties in differentiating between these disorders highlight the necessity of a thorough evaluation and increased clinical suspicion in cases of movement disorders. For treatment outcomes to be optimized and to resolve patient distress, prompt and accurate diagnosis is essential.

BACKGROUND
With recent technological advances, magnetic resonance imaging (MRI) has offered new sequences that can evaluate the real-time motion of anatomic structures. This study aims to evaluate the interobserver agreement in the diagnosis of diaphragmatic dysfunctions using bi-parametric MRI, in which dynamic sequences for diaphragm movement and static sequences for soft tissue resolution are used together to provide a visualization of the diaphragm.
METHODOLOGY
Twenty-nine cases that underwent a bi-parametric magnetic resonance examination which includes coronal T2 single-shot turbo spin echo and the coronal SENSE single-shot balanced turbo field echo real-time sequences were retrospectively evaluated. The images of the patients were assessed by two independent observers. Cohen's kappa coefficient was calculated to evaluate the interobserver agreement.
RESULTS
The mean age of the patients was 44.86 ± 17.57, ranging from 18 to 80 years. The kappa value was calculated as 0.889, indicating a strong agreement between the interobservers.
CONCLUSIONS
Our experience suggests that bi-parametric MRI is a promising tool in the evaluation of diaphragmatic abnormalities.

One of the bacterial infections caused by tympanic membrane perforation is otitis media (OM). Middle ear inflammation causes continuous pain and can be accompanied by aftereffects such as facial nerve paralysis if repeated chronically. Therefore, it is necessary to develop an artificial tympanic membrane (TM) that can effectively regenerate the eardrum due to the easy implantation and removal of OM inflammation. In this study, we synthesized hydrogel by mixing gelatin and polyacrylamide. Cefuroxime sodium salt was then incorporated into this hydrogel to both regenerate the TM and treat OM. Cytotoxicity experiments confirmed the biocompatibility of hydrogels equipped with antibiotics, and we conducted drug release and antibacterial experiments to examine continuous drug release. Through experiments, we have verified the excellent biocompatibility, drug release ability, and antibacterial effectiveness of hydrogel. It holds the potential to serve as an effective strategy for treating OM and regenerating TM as a drug delivery substance.

BACKGROUND
Acute flaccid paralysis (AFP) is a complex clinical syndrome with various aetiologies. If untreated, AFP may lead to death due to failure of respiratory muscles. Tick paralysis, which is a noninfectious neurologic syndrome of AFP, occurs following tick attachment, engorgement, and injection of tick saliva toxins. There is no specific diagnostic test for tick paralysis, and mortality increases as definitive diagnosis is delayed. Although metabolomic investigation of tick saliva was conducted, there is a lack of research on metabolomic evaluation of hosts affected by tick paralysis.
OBJECTIVES
Thus, the aim of this study is to investigate metabolomic changes in serum samples of dogs with tick paralysis due to Rhipicephalus sanguineus using NMR-based metabolomics and to identify potential diagnostic/prognostic markers.
MATERIALS AND METHODS
Forty dogs infested with R. sanguineus, with clinical findings compatible with AFP and with a confirmed tick paralysis diagnosis ex juvantibus, constituted the Paralysis Group. Ten healthy dogs, which were admitted either for vaccination and/or check-up purposes, constituted the Control Group. After the confirmation tick paralysis, medical history, vaccination and nutritional status, body surface area and estimated tick numbers of all the dogs were noted. Physical examination included body temperature, heart and respiratory rate, capillary refill time evaluation and Modified Glasgow Coma Scale calculation. Serum samples were extracted from venous blood samples of all the dogs and were prepared for NMR analysis, and NMR-based metabolomics identification and quantification were performed.
RESULTS
NMR-based serum metabolomics of the present study revealed distinct up/down-regulated expressions, presenting a promising avenue. Moreover, it was observed that energy metabolism and especially liver functions were impaired in dogs with tick paralysis, and not only the respiratory system but also the kidneys were affected.
CONCLUSION
It was concluded that the present approach may help to better understand the pathological mechanisms developing in cases of AFP due to tick paralysis.

Meta-Analysis Review
BACKGROUND
The relationship between amniotic fluid inflammatory biomarkers and preterm birth in second- or third-trimester pregnancy has been a focus, and understanding the correlation between these markers and preterm birth is important for early identification and intervention in preterm birth. The aim of this study was to explore potential inflammatory biomarkers in second- or third-trimester pregnancy amniotic fluid associated with preterm birth.
METHODS
On November 30, 2023, we searched literature involved the influence of second- or third-trimester pregnancy amniotic fluid inflammatory biomarkers on preterm birth through PubMed, Web of Science, Embase, Scope, CNKI, WanFang, VIP and China Biomedical Databases. The search languages were Chinese and English. Included outcomes indexes were combined utility analysis via R software.
RESULTS
A total of 11 articles were included in the combined utility analysis. This combined analysis revealed significant differences in several inflammatory biomarkers in amniotic fluid between the two groups (MD = 6.87, 95%CI: 0.26 - 13.47, P < 0.01); the difference in amniotic fluid IL-6 between the two groups (MD = 5.73, 95%CI: 3.13-8.32, P < 0.01); the difference in amniotic fluid IL-10 between the two groups (MD = 0.11, 95%CI: -3.26-3.48, P < 0.01); the difference in amniotic fluid CRP between the two groups (MD = 21.34, 95%CI: 11.69-30.89, P < 0.01); the difference in amniotic fluid MCP-1 between the two groups (MD = 312.14, 95%CI: 211.34-412.97, P < 0.01); the difference in the amniotic fluid MMP-9 between the two groups (MD = 0.86, 95%CI: -0.10-1.82, P < 0.01); and the difference in TNF-α in amniotic fluid between the two groups (MD = 22.78, 95%CI: -5.05-50.61, P < 0.01).
CONCLUSIONS
The inflammatory biomarkers IL-1β, IL-6, IL-10, CRP, TNFα, MCP-1 and MMP-9 in the amniotic fluid of patients in the second- or third-trimester pregnancy were all correlated with preterm birth.
