To investigate the risk factors of acute symptomatic seizures (ASS) and epilepsy in children with myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD). A ambispective cohort study was used including 74 children with MOGAD who were admitted to the Department of Pediatrics of Peking University First Hospital from January 2013 to June 2023 and were followed up. Demographic information, clinical information, treatment status, ASS and epilepsy status were collected. The clinical phenotypes were classified. According to the presence or absence of ASS in the course of disease, the children and the course of disease were divided into groups with and without ASS. Chi-square test, Fisher exact test and Mann Whitney test were used to analyze the correlation between symptoms and auxiliary examination characteristics and the occurrence of ASS in the two groups of children. Multivariate Logistic regression analysis was used for multivariate analysis. The onset age of the 74 children with MOGAD was 6.58 (3.80, 9.67) years, including 38 females (51.4%) and 36 males (48.6%). The duration of the final follow-up was 2.67 (1.10, 4.12) years, with a total of 239 times acute clinical episodes. ASS occurred in 39.2% (29/74) children during the course of disease and in 29.3% (70/239) of attacks. The common phenotypes were ADEM (67 times (28.0%)), optic neuritis (37 times (15.4%)) and cerebral cortical encephalitis (31 times (13.0%)) in 239 times acute clinical episodes. The incidence of ASS in ADEM and cerebral cortical encephalitis phenotype was 28.4%(19/67) and 100.0% (31/31), respectively. Multivariate analysis showed that cortical involvement on magnetic resonance imaging during clinical attacks was an independent risk factor for ASS (=-1.49, =0.23) after excluding attacks involving only optic nerve or spinal cord (49 episodes). During the follow-up, 5 children (6.8%) had epilepsy, and all children with epilepsy had multiple clinical attacks of MOGAD and previous ASS. Cortical involvement on magnetic resonance imaging during clinical episodes is an independent risk factor for ASS in children with MOGAD. All MOGAD children with epilepsy had ASS and multiple MOGAD clinical episodes in the past.

To investigate the effects of modified endoscopic retrograde appendicitis therapy (mERAT) on the treatment of children with different severities of acute appendicitis. This study was a case-control study. A total of 586 children with acute appendicitis, who were admitted to the Pediatric Department of Second Affiliated Hospital of Air Force Medical University between January 2019 and November 2023, were selected as the research subjects. According to the severity of the disease, the patients were divided into simple appendicitis group, suppurative appendicitis group and perforated appendicitis group. The baseline data, hospitalization treatment and costs, outcomes, and recurrence in each group were analyzed, and the difference in the effectiveness of mERAT between the groups were compared by Kruskal-Wallis test and test. Among 586 children, there were 338 males and 248 females. The age at onset was 7.0 (4.6, 9.4) years. There were 475 cases of simple appendicitis, 78 cases of suppurative appendicitis, and 33 cases of perforated appendicitis. There were no significant differences in age and gender among the three groups (=0.59, =3.31, both >0.05). However, there were statistically significant differences in body temperature, white blood cell counts, neutrophil percentage, lymphocyte percentage, nausea or vomiting, right lower abdominal pain, umbilical pain, right lower abdominal tenderness, and right lower abdominal rebound pain (=7.56, 161.52, 169.11, and 169.61, =12.05, 13.82, 12.05, 7.74, 20.35, and 94.61, all <0.05). Also, the treatment time, postoperative hospital stay, total hospital stay, and cost showed statistically significant differences (4.70, 33.66, 34.99, 30.37, all <0.05). There was no significant difference in the initial treatment success rate (98.1% (466/475) 98.7% (77/78) 90.9% (30/33), =0.057). During the 30 (23, 36) months of follow-up, the recurrence rate was 7.9% (35/433) in the simple appendicitis group, 20.8% (15/72) in the suppurative appendicitis group, and 30.0% (9/30) in the perforated appendicitis group, with a statistically significant difference (=23.56, 0.001). Among the children with recurrent appendicitis, 15 cases still chose mERAT, of them 11 cases (31.2%) had simple appendicitis, 2 cases (2/15) had suppurative appendicitis, and 2 cases (2/9) had perforated appendicitis.The latest time to recurrence in the 3 groups was 32, 35 and 10 months, respectively. Treatment with mERAT has a good effect in pediatric simple appendicitis, but has a higher recurrence rate despite a better initial treatment success rate in suppurative appendicitis and perforated appendicitis.

Cardiotrophin-1 (CT-1), a member of the interleukin (IL)-6 cytokine family, has renoprotective effects in mouse models of acute kidney disease and tubulointerstitial fibrosis, but its role in glomerular disease is unknown. To address this, we used the mouse model of nephrotoxic nephritis to test the hypothesis that CT-1 also has a protective role in immune-mediated glomerular disease. Using immunohistochemistry and analysis of single-cell RNA-sequencing data of isolated glomeruli, we demonstrate that CT-1 is expressed in the glomerulus in male mice, predominantly in parietal epithelial cells and is downregulated in mice with nephrotoxic nephritis. Furthermore, analysis of data from patients revealed that human glomerular disease is also associated with reduced glomerular CT-1 transcript levels. In male mice with nephrotoxic nephritis and established proteinuria, administration of CT-1 resulted in reduced albuminuria, prevented podocyte loss, and sustained plasma creatinine, compared with mice administered saline. CT-1 treatment also reduced fibrosis in the kidney cortex, peri-glomerular macrophage accumulation and the kidney levels of the pro-inflammatory mediator complement component 5a. In conclusion, CT-1 intervention therapy delays the progression of glomerular disease in mice by preserving kidney function and inhibiting renal inflammation and fibrosis.

Pulmonary embolism (PE) is the third most common type of cardiovascular disease and carries a high mortality rate of 30% if left untreated. Although it is commonly known that individuals who suffer heart failure (HF) are more likely to experience a pulmonary embolism, little is known concerning the prognostic relationship between acute PE and HF. This study aims to evaluate the prognostic usefulness of heart failure and pro-BNP in pulmonary embolism cases. A scientific literature search, including PubMed, Medline, and Cochrane reviews, was used to assess and evaluate the most pertinent research that has been published. The findings showed that increased N-terminal brain natriuretic peptide (NT-proBNP) levels could potentially identify pulmonary embolism patients with worse immediate prognoses and were highly predictive of all-cause death. Important prognostic information can be obtained from NT-proBNP and Heart-type Fatty Acid Binding Proteins (H-FABP) when examining individuals with PE. The heart, distal tubular cells of the renal system, and skeletal muscle are where H-FABP is primarily found, with myocardial cells having the highest concentration. Recent studies have indicated that these biomarkers may also help assess the severity of PE and its long-term risk.

People with sickle cell disease (SCD) often experience chronic pain as well as unpredictable episodes of acute pain, which significantly affect their quality of life and life expectancy. Current treatment strategies for SCD-associated pain primarily rely on opioid analgesics, which have limited efficacy and cause serious adverse effects. Cannabis has emerged as a potential alternative, yet its efficacy remains uncertain. In this study, we investigated the antinociceptive effects of Δ-tetrahydrocannabinol (THC), cannabis' intoxicating constituent, in male HbSS mice, which express >99% human sickle hemoglobin, and male HbAA mice, which express normal human hemoglobin A, as a control. Acute THC administration (0.1-3 mg-kg, intraperitoneal, i.p.) dose-dependently reduced mechanical and cold hypersensitivity in HbSS, but not HbAA mice. In the tail-flick assay, THC (1 and 3 mg-kg, i.p.) produced substantial antinociceptive effects in HbSS mice. By contrast, THC (1 mg-kg, i.p.) did not alter anxiety-like behavior (elevated plus maze) or long-term memory (24-h novel object recognition). Subchronic THC treatment (1 and 3 mg-kg, i.p.) provided sustained relief of mechanical hypersensitivity but led to tolerance in cold hypersensitivity in HbSS mice. Together, the findings identify THC as a possible therapeutic option for the management of chronic pain in SCD. Further research is warranted to elucidate its mechanism of action and possible interaction with other cannabis constituents. The study explores THC's efficacy in alleviating pain in sickle cell disease (SCD) using a humanized mouse model. Findings indicate that acute THC administration reduces mechanical and cold hypersensitivity in SCD mice without impacting emotional and cognitive dysfunction. Subchronic THC treatment offers sustained relief of mechanical hypersensitivity but leads to cold hypersensitivity tolerance. These results offer insights into THC's potential as an alternative pain management option in SCD, highlighting both its benefits and limitations.

Aggressive hydration with lactated Ringer's solution versus plasma solution for the prevention of post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (ALPS study): protocol for a multicentre, double-blind, randomised controlled trial.
INTRODUCTION
Endoscopic retrograde cholangiopancreatography (ERCP) plays an indispensable role in treating pancreato-biliary diseases but carries a risk of post-ERCP pancreatitis (PEP). Despite advances in the prevention strategies, prevention of PEP remains imperfect, necessitating more refined hydration methods. This study investigates the effectiveness of lactated Ringer's solution versus plasma solution in preventing PEP.
METHOD AND ANALYSIS
This multicentre, double-blind, randomised controlled trial, will be initiated by the investigator-sponsor, and conducted in three tertiary centres in South Korea. The aim of this study is to assess the effectiveness of hydration in preventing PEP in patients with naïve papillae. It will target patients with naïve papillae, focusing on those at medium to high risk of PEP. Patients aged ≤18 years and those with serious comorbidities, acute/chronic pancreatitis and various other medical conditions will be excluded. Eligible participants will be randomly assigned into two arms in equal numbers: (1) PEP prevention using lactated Ringer's solution and (2) PEP prevention using plasma solution. The primary outcome of this study will be the occurrence of PEP, and secondary outcomes will be additional risk factors and potential adverse events related to ERCP. With a total enrolment of 844 patients, the study will be able to detect significant differences between the intervention arms.
ETHICS AND DISSEMINATION
Ethical approval is obtained from each institution (Asan Medical Centre, 2023-0382; Seoul National University Hospital, H-2302-05-1404; Samsung Medical Centre, SMC 2023-02-001-009). All participants provided informed consent following clear explanation of the study procedures. The results of the study will be disseminated in peer-reviewed journals and research conferences.

The wildlife and livestock interface is vital for wildlife conservation and habitat management. Infectious diseases maintained by domestic species may impact threatened species such as Asian bovids, as they share natural resources and habitats. To predict the population impact of infectious diseases with different traits, we used stochastic mathematical models to simulate the population dynamics over 100 years for 100 times in a model gaur () population with and without disease. We simulated repeated introductions from a reservoir, such as domestic cattle. We selected six bovine infectious diseases; anthrax, bovine tuberculosis, haemorrhagic septicaemia, lumpy skin disease, foot and mouth disease and brucellosis, all of which have caused outbreaks in wildlife populations. From a starting population of 300, the disease-free population increased by an average of 228% over 100 years. Brucellosis with frequency-dependent transmission showed the highest average population declines (-97%), with population extinction occurring 16% of the time. Foot and mouth disease with frequency-dependent transmission showed the lowest impact, with an average population increase of 200%. Overall, acute infections with very high or low fatality had the lowest impact, whereas chronic infections produced the greatest population decline. These results may help disease management and surveillance strategies support wildlife conservation.

Dengue is among the most important mosquito-borne viral diseases worldwide. Although its acute manifestations are well known, little is known about the long-term impact of dengue on the population's health status. Madeira Island experienced a single outbreak of autochthonous dengue from September 2012 to March 2013. To extend our knowledge about the clinical impact of the outbreak on this naive population, we applied an online questionnaire to 168 adults diagnosed with dengue at the time to characterize retrospectively their symptoms during the infection and to identify long-term manifestations, possibly triggered by dengue. The most frequent symptoms during the clinical period, reported by more than three-quarters of our participants, were fever, myalgia, extreme tiredness, and headaches, whereas vomiting, pruritus, nausea, retro-orbital pain, and arthralgia occurred in 35% to 50% of participants. In the 8 years after dengue, 61.5% of participants reported at least one recurrent previously nonexistent symptom, the most frequent being headaches, abundant hair loss, extreme tiredness, arthralgia, and myalgia, experienced by 25% to 35% of participants. Nearly 20% of the participants with persistent symptoms reported the onset of chronic illness in the 4 years after dengue, most frequently ophthalmological and autoimmune diseases (5.6% each), versus only 2.2% of chronic disease onset in participants without persistent symptoms. Our results suggest that the occurrence of persistent symptoms after primary dengue might be more frequent than anticipated and may persist for several years, having an impact on the health status and well-being of a considerable proportion of the infected population.

Neuroinflammation, characterized by microglial activation and the release of multiple inflammatory mediators, is a key factor in acute glaucomatous injury leading to retinal ganglion cell (RGC) death and ultimately irreversible vision loss. Irisin, a novel exercise-induced myokine, has demonstrated anti-inflammatory activity in ischemia/reperfusion injuries across multiple organs and has displayed a significant neuroprotective role in experimental stroke disease models. This study examined the protective impact of irisin and investigated its potential mechanism involved in this process utilizing an acute ocular hypertension (AOH)-induced retinal injury model in mice and a microglia inflammation model induced by lipopolysaccharide (LPS). There was a transient downregulation of irisin in the retina after AOH injury, with parallel emergence of retinal neuroinflammation and RGC death. Irisin attenuated retinal and optic nerve damage and promotes the phenotypic conversion of microglia from M1 to M2. Mechanistically, irisin significantly upregulated the expression of integrin αVβ5, p-AMPK, and autophagy-related markers. Integrin αVβ5 was highly expressed on microglia but hardly expressed on RGC. The integrin αVβ5 inhibitor cilengitide, the AMPK inhibitor dorsomorphin, and the autophagy inhibitor 3-Methyladenine (3-MA) blocked the neuroprotective effects of irisin. Our results suggest irisin attenuates acute glaucoma-induced neuroinflammation and RGC death by activating integrin αVβ5/AMPK in microglia and promoting autophagy. It should be considered a potential neuroprotective therapy for acute glaucoma.
