Objective To investigate the cranial magnetic resonance imaging （MRI） features of patients with hepatolenticular degeneration （also known as Wilson disease，WD） and epilepsy， and to identify the neuroimaging risk factors for seizures in WD patients. Methods A total of 69 WD patients with epilepsy who were hospitalized in Affiliated Hospital of Neurology Institute， Anhui University of Chinese Medicine， from January 2018 to November 2025 were enrolled as study group， while 80 WD patients without seizures， matched for sex and age， during the same period of time were randomly selected as control group. Cranial MRI findings were compared between the two groups. Results There were 69 WD patients （43 male patients and 26 female patients） in the study group， with a mean age of （29.46±8.58） years at the time of attending the hospital， and all these patients had abnormal electroencephalogram （EEG） findings. There were no significant differences between the two groups in age of onset，disease duration， WD subtype， and serum copper. Cranial MRI showed that the putamen was the most common site of brain injury （47 patients， 68.1%）， followed by the frontal lobe （40 patients，58.0%） and the parietal lobe （31 patients，44.9%）， and there was a significantly higher probability of epilepsy in patients with abnormal lesions in the frontal， temporal， or parietal lobes （P<0.05）. Conclusion While the putamen is the most common site of brain injury in WD patients with epilepsy， frontal or temporal lobe injuries are neuroimaging risk factors for seizures in such patients.

OBJECTIVES

Clinical pathways (CPs) ensure adherence to heart failure (HF) management guidelines. To optimize quality care in a low resource setting, an evidence-based care pathway for the management of acute HF was implemented at the emergency department (ED) of the Philippine General Hospital (PGH), the designated national tertiary hospital and referral center. This study aimed to describe the characteristics of adults with acute HF admitted at the ED and evaluate the quality of care they received, measured using physician adherence to the hospital’s acute heart failure CP.

METHODS

This was a retrospective, descriptive cohort study. We reviewed the inpatient charts of all adult patients with acute HF admitted to the ED of the PGH and referred to the Division of Cardiovascular Medicine between December 1, 2022 and May 31, 2023. Quality of care was assessed based on adherence to quality indicators adapted from routine and conditional order sets detailed in the pathway. Descriptive statistics was utilized to describe patient characteristics, quality of care, and outcomes.

RESULTS

Two hundred thirty-six (236) patients were included, with a mean age of 51.8 years. Majority were male (53.4%); hypertension (61.4%) and ischemic heart disease (53.8%) were the most common comorbidities, and infection the most common precipitant of decompensation (60.6%). There were optimal adherence rates to routine orders, which included referrals to Internal Medicine and Cardiology, baseline vital signs monitoring, fluid intake and output monitoring, chest radiograph, complete blood count, blood urea nitrogen, sodium, potassium, prothrombin time, partial thromboplastin time, arterial blood gas, urinalysis, and N-terminal pro b-type natriuretic peptide. Conditional orders, such as oxygen support, focused echocardiography, thyroid - stimulating hormone, and the use of vasopressors, diuretics, and venous thromboembolism prophylactic agents, were optimally performed when warranted. However, we noted suboptimal adherence to certain resource-intensive conditional orders, such as hourly monitoring of urine output (61.4%), hooking to cardiac monitor (53.8%), and performance of 12-lead ECG within 10 minutes (56.8%). Further, only 43.9% of patients were referred to the intensive care unit. Troponin I, calcium, magnesium, and albumin were ordered in excess.

CONCLUSION

Overall adherence rate of physicians to the hospital’s Acute Heart Failure Pathway was satisfactory. Work is needed to improve adherence to hourly urine output monitoring, consistent hooking to cardiac monitor, and timely performance of 12-lead ECG – an effort that begins with expanding in-hospital diagnostic equipment and human resource supply. We recommend continuous pathway implementation with periodic evaluation and stakeholder feedback to further improve quality of care.

BACKGROUND

Spinocerebellar Ataxia (SCA) represents a rare and heterogeneous group of neurodegenerative disorders, typically characterized by the progressive loss of coordination of movement, resulting primarily from cerebellar dysfunction. This case report discusses the history, clinical presentation, and diagnostic findings of a patient who exhibited symptoms suggestive of SCA. Given the notable familial pattern, further evaluation was undertaken using genetic testing. The objective of this paper is to present the clinical, genetic findings, and inheritance pattern of a patient and her family with SCA.

CASE PRESENTATION

Our case is a 36-year-old Filipino female with progressive cerebellar dysfunction for over a decade. Cranial Magnetic Resonance Imaging (MRI) revealed bilateral cerebellar atrophy. Genetic testing identified a Variant of Uncertain Significance (VUS) in the inositol 1,4,5- triphosphate receptor type 1 (ITPR1) gene, a finding consistent with Spinocerebellar Ataxia type 15 (SCA 15). This represents the first reported case of SCA 15 in the Philippines and in Asia.

A detailed pedigree assessment revealed that 18 immediate and extended family members had similar symptoms suggestive of hereditary ataxia. Ten relatives had already passed away, and four could not be contacted for further evaluation. Three available family members were examined and likewise demonstrated comparable cerebellar findings, supporting a familial pattern of the disease.

CONCLUSION

The findings from this case series suggest that SCA 15 may be present in Filipino families, with an autosomal dominant (AD) inheritance pattern. While no data on the prevalence or incidence of SCA15 in the Philippines currently exists, this report calls attention to the need for further research and genetic studies within the Filipino population.

Introduction: Steroid-responsive encephalopathy associated with thyroiditis (STREAT) is a rare clinical entity. Clinical presentations of STREAT can range from a strokelike presentation to psychiatric symptoms. STREAT is diagnosed based on four major criteria which include altered cognitive function, new or worsening psychiatric symptoms, elevated antithyroid antibodies, and exclusion of infectious, toxic, metabolic, or neoplastic causes. Corticosteroids are the cornerstone of treatment, with reported excellent response in neurocognitive symptoms resolution. Case: This was a case of a 48-year-old male with Graves’s disease who underwent radioiodine therapy 4 months earlier and was started on levothyroxine 100 mcg 2 weeks prior to presentation. He presented with 4 days of behavioral symptoms, irritable mood with auditory and visual hallucinations. There was no history of fever, headache, limb weakness, or seizure. On general appearance, the patient was agitated, talking incoherently, and disorientated with normal vitals. There was no delayed relaxation of the reflex. The examination of the cranial nerve, motor, sensory, and cerebellar system was normal. A lumbar puncture showed normal opening pressure with a high protein CSF content of 1,596 mg/L. The thyroid-stimulating hormone (TSH) was elevated at 72.7 uIU/mL and T4 at 9.56 pmol/L. Serum antithyroid peroxidase was elevated at 877.42 IU/mL, and antiTSH receptor antibody at 21.30 IU/L. CSF oligonal band, serum aquaporin-4, and viral screening were negative; noncontrasted computed tomography brain revealed normal findings. Based on the clinical history and examination, a diagnosis of STREAT was made at the emergency department. The patient was initiated on hydrocortisone 100 mg three times a day. Within 24–48 hours of steroid therapy, marked improvement and subsequent resolution of the mental status and behavioral symptoms were seen. Conclusion Hashimoto’s thyroiditis can rarely lead to STREAT, a condition with diverse neurological manifestations, where early recognition and prompt corticosteroid therapy are essential for favorable outcomes.

Cardiovascular disease (CVD) poses a serious threat to human health. Exercise plays an important role in both the prevention and treatment of CVD and is one of the key non-pharmacological interventions. Exercise can regulate the level of exerkine secreted by different tissue cells, directly affect the cardiovascular system or play a role in cardiovascular protection by improving cardiovascular risk factors. Exerkine such as meteorin-like protein (Metrnl), brain-derived neurotrophic factor (BDNF), fibroblast growth factor 21 (FGF21), and exosomal microRNA (miRNA) play an important role in regulating vascular and cardiac diseases such as atherosclerosis, heart failure, cardiac ischemia-reperfusion and myocardial infarction, as well as their risk factors. Exploring the signaling pathways and mechanisms by which Metrnl, BDNF, FGF21, and exosomal miRNAs exert cardiovascular protective effects can provide novel insights into exercise-based strategies for preventing and treating cardiovascular diseases.

OBJECTIVES: The neurotoxicity of carbon monoxide (CO) to the central nervous system is a key pathogenesis of delayed encephalopathy after acute carbon monoxide poisoning (DEACMP). Our previous study found that retinoic acid (RA) can suppress the neurotoxic effects of CO. This study further explores, in vivo and in vitro, the molecular mechanisms by which RA alleviates CO-induced central nervous system damage. METHODS: A cytotoxic model was established using the mouse hippocampal neuronal cell line HT22 and primary oligodendrocytes exposed to CO, and a DEACMP animal model was established in adult Kunming mice. Cell viability and apoptosis of hippocampal neurons and oligodendrocytes were assessed using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and Annexin V/propidium iodide (PI) double staining. The transcriptional and protein expression of each gene was detected using real-time fluorescence quantitative PCR (RT-qPCR) and Western blotting. Long noncoding RNA (lncRNA) <i>SNHG15i> and <i>LINGO-1i> were knocked down or overexpressed to observe changes in neurons and oligodendrocytes. In DEACMP mice, SNHG15 or LINGO-1 were knocked down to assess changes in central nervous tissue and downstream protein expression. RESULTS: RA at 10 and 20 μmol/L significantly reversed CO-induced apoptosis of hippocampal neurons and oligodendrocytes, downregulation of <i>SNHG15i> and <i>LINGO-1i>, and upregulation of brain-derived neurotrophic factor (BDNF) and tyrosine kinase receptor B (TrkB) (all <i>Pi><0.05). Overexpression of <i>SNHG15i> or <i>LINGO-1i> weakened the protective effect of RA against CO-induced cytotoxicity (all <i>Pi><0.05). Knockdown of <i>SNHG15i> or <i>LINGO-1i> alleviated CO-induced apoptosis of hippocampal neurons and oligodendrocytes and upregulated BDNF and TrkB expression levels (all <i>Pi><0.05). Experiments in DEACMP model mice showed that knockdown of <i>SNHG15i> or <i>LINGO-1i> mitigated central nervous system injury in DEACMP (all <i>Pi><0.05). CONCLUSIONS RA alleviates CO-induced apoptosis of hippocampal neurons and oligodendrocytes, thereby reducing central nervous system injury and exerting neuroprotective effects. LncRNA <i>SNHG15i> and <i>LINGO-1i> are key molecules mediating RA-induced inhibition of neuronal apoptosis and are associated with the BDNF/TrkB pathway. These findings provide a theoretical framework for optimizing the clinical treatment of DEACMP and lay an experimental foundation for elucidating its molecular mechanisms.

Patients with depression are more likely to have chronic gastrointestinal (GI) symptoms than the general population, but such symptoms are considered only somatic symptoms of depression and lack special attention. There is a chronic lack of appropriate diagnosis and effective treatment for patients with depression accompanied by GI symptoms, and studying the association between depression and GI disorders (GIDs) is extremely important for clinical management. There is growing evidence that depression is closely related to the microbiota present in the GI tract, and the microbiota-gut-brain axis (MGBA) is creating a new perspective on the association between depression and GIDs. Identifying and treating GIDs would provide a key opportunity to prevent episodes of depression and may also improve the outcome of refractory depression. Current studies on depression and the microbially related gut-brain axis (GBA) lack a focus on GI function. In this review, we combine preclinical and clinical evidence to summarize the roles of the microbially regulated GBA in emotions and GI function, and summarize potential therapeutic strategies to provide a reference for the study of the pathomechanism and treatment of depression in combination with GI symptoms.

OBJECTIVES: To explore the therapeutic mechanism of <i>Chaihu Shugani> (CHSG) Decoction for improving cognitive impairment in rats with epilepsy induced by lithium chloride and pilocarpine. METHODS: Male SD rat models of cognitive impairment model after epilepsy induced by intraperitoneal injection with lithium chloride and pilocarpine were randomly divided into 5 groups (<i>ni>=12) for treatment with daily gavage of saline, donepezil (90 mg/kg), or CHSG Decoction at 2.5, 5.0, 10, 20 and 40 g/kg for 4 consecutive weeks, with 10 rats with intraperitoneal injection with saline as the blank control group. Morris water maze test was used to evaluate cognitive and behavioral changes of the rats after treatment. The mRNA and protein expressions of ASIC1, NR1, NR2A and NR2B in the hippocampus of rats were detected using RT-qPCR and Western blotting. RESULTS: Compared with those with saline treatment, the rat models treated with CHSG Decoction at 5 and 10 g/kg showed significantly shortened escape latency and prolonged stay in the target quadrant with increased number of platform crossings in Morris water maze test. CHSG Decoction treatment at the two doses significantly increased ASIC1, NR1, NR2A and NR2B protein expressions in the hippocampus of the rat models, and their mRNA expression levels were all increased significantly after the treatment at the doses above 2.5 g/kg. CONCLUSIONS CHSG Decoction can improve cognitive impairment in rats after epilepsy possibly by regulating the expression and channel activity of NMDAR protein and its subunit protein via upregulating ASIC1 to modulate neuronal excitability and synaptic plasticity in the hippocampus.

Neurodegeneration involves a wide range of neuropathological alterations affecting the integrity, physiology, and architecture of neural cells. Many studies have demonstrated neurodegeneration in different animals. In the case of Alzheimer's disease (AD), spontaneous animal models should display two neurohistopathological hallmarks: the deposition of β-amyloid and the arrangement of neurofibrillary tangles. However, no natural animal models that fulfill these conditions have been reported and most research into AD has been performed using transgenic rodents. Recent studies have also demonstrated that toothed whales - homeothermic, long-lived, top predatory marine mammals - show neuropathological signs of AD-like pathology. The neuropathological hallmarks in these cetaceans could help to better understand their endangered health as well as neurodegenerative diseases in humans. This systematic review analyzes all the literature published to date on this trending topic and the proposed causes for neurodegeneration in these iconic marine mammals are approached in the context of One Health/Planetary Health and translational medicine.

Approximately 30%-40% of epilepsy patients do not respond well to adequate anti-seizure medications (ASMs), a condition known as pharmacoresistant epilepsy. The management of pharmacoresistant epilepsy remains an intractable issue in the clinic. Its early prediction is important for prevention and diagnosis. However, it still lacks effective predictors and approaches. Here, a classical model of pharmacoresistant temporal lobe epilepsy (TLE) was established to screen pharmacoresistant and pharmaco-responsive individuals by applying phenytoin to amygdaloid-kindled rats. Ictal electroencephalograms (EEGs) recorded before phenytoin treatment were analyzed. Based on ictal EEGs from pharmacoresistant and pharmaco-responsive rats, a convolutional neural network predictive model was constructed to predict pharmacoresistance, and achieved 78% prediction accuracy. We further found the ictal EEGs from pharmacoresistant rats have a lower gamma-band power, which was verified in seizure EEGs from pharmacoresistant TLE patients. Prospectively, therapies targeting the subiculum in those predicted as "pharmacoresistant" individual rats significantly reduced the subsequent occurrence of pharmacoresistance. These results demonstrate a new methodology to predict whether TLE individuals become resistant to ASMs in a classic pharmacoresistant TLE model. This may be of translational importance for the precise management of pharmacoresistant TLE.
