INTRODUCTION: Seizure disorders have often been found to be associated with corpus callosum injuries, but in most cases, they remain undiagnosed. Understanding the clinical, electrographic, and neuroradiological alternations can be crucial in delineating this entity.
OBJECTIVE: This systematic review aims to analyze the effects of corpus callosum injuries on seizure semiology, providing insights into the neuroscientific and clinical implications of such injuries.
METHODS: Adhering to the PRISMA guidelines, a comprehensive search across multiple databases, including PubMed/Medline, NIH, Embase, Cochrane Library, and Cross-ref, was conducted until September 25, 2023. Studies on seizures associated with corpus callosum injuries, excluding other cortical or sub-cortical involvements, were included. Machine learning (Random Forest) and deep learning (1D-CNN) algorithms were employed for data classification.
RESULTS: Initially, 1250 articles were identified from the mentioned databases, and additional 350 were found through other relevant sources. Out of all these articles, 41 studies met the inclusion criteria, collectively encompassing 56 patients The most frequent clinical manifestations included generalized tonic-clonic seizures, complex partial seizures, and focal seizures. The most common callosal injuries were related to reversible splenial lesion syndrome and cytotoxic lesions. Machine learning and deep learning analyses revealed significant correlations between seizure types, semiological parameters, and callosal injury locations. Complete recovery was reported in the majority of patients post-treatment.
CONCLUSION: Corpus callosum injuries have diverse impacts on seizure semiology. This review highlights the importance of understanding the role of the corpus callosum in seizure propagation and manifestation. The findings emphasize the need for targeted diagnostic and therapeutic strategies in managing seizures associated with callosal injuries. Future research should focus on expanding the data pool and exploring the underlying mechanisms in greater detail.
Hepatitis B Virus (HBV) is a stealthy and insidious pathogen capable of inducing chronic necro-inflammatory liver disease and hepatocellular carcinoma (HCC), resulting in over one million deaths worldwide per year. The traditional understanding of Chronic Hepatitis B (CHB) progression has focused on the complex interplay among ongoing virus replication, aberrant immune responses, and liver pathogenesis. However, the dynamic progression and crucial factors involved in the transition from HBV infection to immune activation and intrahepatic inflammation remain elusive. Recent insights have illuminated HBV's exploitation of the sodium taurocholate co-transporting polypeptide (NTCP) and manipulation of the cholesterol transport system shared between macrophages and hepatocytes for viral entry. These discoveries deepen our understanding of HBV as a virus that hijacks hepatocyte metabolism. Moreover, hepatic niche macrophages exhibit significant phenotypic and functional diversity, zonal characteristics, and play essential roles, either in maintaining liver homeostasis or contributing to the pathogenesis of chronic liver diseases. Therefore, we underscore recent revelations concerning the importance of hepatic niche macrophages in the context of viral hepatitis. This review particularly emphasizes the significant role of HBV-induced metabolic changes in hepatic macrophages as a key factor in the transition from viral infection to immune activation, ultimately culminating in liver inflammation. These metabolic alterations in hepatic macrophages offer promising targets for therapeutic interventions and serve as valuable early warning indicators, shedding light on the disease progression.

Pediatric acute myeloid leukemia (AML) is a highly heterogeneous disease making standardized measurable residual disease (MRD) assessment challenging. Currently, patient-specific DNA-based assays are only rarely applied for MRD assessment in pediatric AML. We tested whether quantification of genomic breakpoint-specific sequences via quantitative polymerase chain reaction (gDNA-PCR) provides a reliable means of MRD quantification in children with non-standardrisk AML and compared its results to those obtained with state-of-the-art ten-color flow cytometry (FCM). Breakpointspecific gDNA-PCR assays were established according to Euro-MRD consortium guidelines. FCM-MRD assessment was performed according to the European Leukemia Network guidelines with adaptations for pediatric AML. Of 77 consecutively recruited non-standard-risk pediatric AML cases, 49 (64%) carried a chromosomal translocation potentially suitable for MRD quantification. Genomic breakpoint analysis returned a specific DNA sequence in 100% (41/41) of the cases submitted for investigation. MRD levels were evaluated using gDNA-PCR in 243 follow-up samples from 36 patients, achieving a quantitative range of at least 10-4 in 231/243 (95%) of samples. Comparing gDNA-PCR with FCM-MRD data for 183 bone marrow follow-up samples at various therapy timepoints showed a high concordance of 90.2%, considering a cut-off of ≥0.1%. Both methodologies outperformed morphological assessment. We conclude that MRD monitoring by gDNA-PCR is feasible in pediatric AML with traceable genetic rearrangements and correlates well with FCM-MRD in the currently applied clinically relevant range, while being more sensitive below that. The methodology should be evaluated in larger cohorts to pave the way for clinical application.
The pathogenesis of aortic dissection (AD), an aortic disease associated with high mortality, involves significant vascular inflammatory infiltration. However, the precise relationship between perivascular adipose tissue (PVAT) and aortic dissection remains incompletely understood. The objective of this study is to investigate the role of PVAT inflammation in the pathogenesis of aortic dissection and identify novel therapeutic targets for this disease. The mouse model of aortic dissection was established in this study through intraperitoneal injection of Ang II and administration of BAPN in drinking water. Additionally, control groups were established at different time points including the 2-week group, 3-week group, and 4-week group. qPCR and immunohistochemistry techniques were employed to detect the expression of inflammatory markers and RUNX1 in PVAT surrounding the thoracic aorta in mice. Additionally, an aortic dissection model was established using RUNX1 knockout mice, and the aforementioned indicators were assessed. The 3T3-L1 cells were induced to differentiate into mature adipocytes in vitro, followed by lentivirus transfection for the knockdown or overexpression of RUNX1. The study aimed to investigate the potential cell-to-cell interactions by co-culturing 3T3-L1 cells with A7r5 or RAW264.7 cells. Subsequently, human aortic PVAT samples were obtained through clinical surgery and the aforementioned indicators were detected. In comparison to the control group, the aortic dissection model group exhibited decreased expression of MMP-2 and NF-κB in PVAT, while TNF-α and RUNX1 expression increased. Suppression of RUNX1 expression resulted in increased MMP-2 and NF-κB expression in PVAT, along with decreased TNF-α expression. Overexpression of RUNX1 upregulated the expression levels of NF-Κb, MMP-2, and TNF-α in adipocytes, whereas knockdown of RUNX1 exerted an opposite effect. Macrophages co-cultured with adipocytes overexpressing RUNX1 exhibited enhanced CD86 expression, while vascular smooth muscle cells co-cultured with these adipocytes showed reduced α-SMA expression. In human samples, there was an increase in both RUNX1 and MMP-2 expression levels, accompanied by a decrease in TNF-α and NF-Κb expression. The presence of aortic dissection is accompanied by evident inflammatory alterations in the PVAT, and this phenomenon appears to be associated with the involvement of RUNX1. It is plausible that the regulation of PVAT's inflammatory changes by RUNX1/NF-κB signaling pathway plays a role in the pathogenesis of aortic dissection.
INTRODUCTION: Intestinal manipulation (IM)-induced inflammation could contribute to postoperative ileus (POI) pathophysiology via the modulation of prostanoid pathways. To identify the prostanoids involved, we aimed to characterize the profile of prostanoids and their synthesis enzyme expression in a murine model of POI and to determine whether the altered prostanoids could contribute to POI.
METHODS: Four or 14 h after IM in mice, gastrointestinal (GI) motility and intestinal epithelial barrier (IEB) permeability were assessed in vivo and ex vivo in Ussing chambers. Using high sensitivity liquid chromatography-tandem mass spectrometry, we characterized the tissue profile of polyunsaturated fatty acid metabolites in our experimental model. Finally, we evaluated in vivo the effects of the prostanoids studied upon IM-induced gut dysfunctions.
RESULTS: We first showed that 14 h after IM was significantly faster than jejunal transit at 4 h post-IM, although it remained significantly increased compared to the control. In contrast, we showed that IM-induced inflammation increase in jejunum permeability was similar after four and 14 h. We next showed that expression of prostacyclin synthase and hemopoietic prostaglandin-D synthase mRNA and their products were significantly reduced 14 h after IM as compared to controls. Furthermore, 15-deoxy-delta 12,14-Prostaglandin J2 reduced the IM-induced inflammation increase in IEB permeability but had no effect on GI motility. In contrast, PGI2 increased IM-induced IEB permeability and motility dysfunctions.
CONCLUSIONS: Arachidonic acid derivative contributes differentially to GI dysfunction in POI. The decrease of 15-deoxy-delta 12,14-Prostaglandin J2 levels induced by IM could contribute to impaired GI dysfunctions in POI and could be considered as putative therapeutic targets to restore barrier dysfunctions associated with POI.
The gel-coated external cooling device consists of four water circulating gel coated energy transfer pads, and is placed on the patient's back, abdomen, and both thighs. Depending on the size used, the total surface area ranges between 0.60 and 0.77 m2. It is connected to an automatic thermostat controlling the temperature of the circulating water (4°C to 42°C) based on the patient's core temperature.
The participants will undergo 4 different trial conditions of which all are iso-caloric, but with different intervals of sitting and executing moderate physical activity by treadmill walking corresponding to 45-55% of their individual VO2max/peak values, estimated from the individual's pre-test. The total duration of sedentary- and physical activity time will be identical in each trial condition. This study has a is randomized cross-over design. If found eligible from step 1 and 2 in the inclusion process, participants will be invited to a final screening day in our lab. Eligible participants then consenting to joining the study will continue on to 4 trial days. Due to possible acute rise in insulin for up to 48 hours, a 5-14 day washout period between trials will be used to avoid carryover effects. In the washout periods between experimental conditions the participants will resume their habitual life activities and behaviours, i.e., diet and physical activity patterns. However, from visit 2, during washout the participants will wear accelerometers (ActiGraph GTX3+, Pensacola, FL) during waking hours to objectively measure sedentary time and physical activity. Average sedentary time (hour/day) and time spent in , light-, moderate- and vigorous physical activity intensity (min/day) will be derived. During the main trial days, the participants may read or work on a personal computer during the sedentary time in the respective trial conditions. The sample size calculations with glucose as the primary outcome, are based on the study by Dunstan et al. (2012). They estimated that 19 paired observations were needed to secure a power of 0.90 in order to detect the smallest expected effect size between the interventions, when using a two-tailed test with a significance level of 5%. To account for the possibility of dropouts the sample size in the present project is set to recruit 30 participants, with 25 participants completing the trials, and thus planning for 80% power
The initial physiological change in adolescent girls is the onset of menstruation. The most prevalent challenge they face regarding menstruation is primary dysmenorrhea, characterized by persistent or intermittent pelvic pain in the lower abdomen. The aim of this study was to investigate the influences of stress levels and physical activities on primary dysmenorrhea. A cross-sectional was conducted in Cirebon, Indonesia, in 2023 included young women who had never given birth (nullipara), aged 17-25 years old, had menstruated, and had no history of smoking and alcohol. The data were collected using a set of questionnaires consisting of the Numeric Rating Scale (NRS) to determine primary dysmenorrhea pain, the Depression Anxiety Stress Scales 42 (DASS 42) to determine the level of stress and the International Physical Activity Questionnaire (IPAQ) to determine physical activity. Pearson's correlation test was used to assess the correlation between the variables (stress levels, physical activity, and dysmenorrhea). A total of 150 young women were included in the study. Moderate stress levels (23.3%) and high physical activity (90.7%) were the most prevalent category observed among studied participants. Approximately 42% of them experienced mild dysmenorrhea pain. Our analysis indicated that stress levels and physical activities had strong positive and negative correlations with dysmenorrhea pain levels, with r=0.782 and r=-0.748, respectively, with both had p<0.001. This highlights that controlling stress could be beneficial in preventing dysmenorrhea pain among young women.
BACKGROUND: A single dose of dexamethasone is routinely given during general anesthesia for postoperative nausea and vomiting (PONV) prophylaxis, although the exact dosage and timing of administration may vary between practitioners. The authors aimed to standardize the dosage and timing of this medication when given to adult patients undergoing general anesthesia for elective surgery.
METHODS: Baseline data for 7,483 preintervention cases were analyzed. The researchers attempted to use a standard dose of 8 to 10 mg induction of anesthesia, which, based on a literature review, was effective for PONV prophylaxis, had a similar safety profile as a 4 to 5 mg dose (including in diabetic patients), and may confer additional benefits such as improved prophylaxis and quality of recovery. The interventions included standardizing the medication concentration vials, altering electronic health record quick-select button options, simplifying the intraoperative charting process, and educating the anesthesia providers. The research team then tracked compliance with the standard of care for 2,167 cases after the interventions.
RESULTS: Overall compliance with the standard of care increased from 21.2% preintervention to 53.7% postintervention. The number of patients not receiving dexamethasone was reduced from 29.7% to 19.4%. Patients receiving a compliant dose at a noncompliant time increased from 16.3% to 23.8%. Postanesthesia care unit antiemetic administration also decreased after the interventions.
CONCLUSION: This study showed improvements in compliance with the dosage of medication with the interventions. However, compliance with the timing of administration remains challenging.
PDR001 will be administered once every 3 weeks via i.v. infusions over 30 minutes, respectively. Infusions of each antibody can be extended to up to 2 hours if clinically indicated. A scheduled dose of ongoing study drugs may be delayed by up to 7 days to recover from previous AEs or a missed visit. If a scheduled dose of ongoing study drugs is delayed longer than 7 days due to an unresolved AE, the administration should be skipped and treatment resumed at the next scheduled dose. The assessment schedule will be shifted accordingly.
RATIONALE: Acute promyelocytic leukaemia (APL) is a rare subtype of acute myelogenous leukaemia. With advances in treatment regimens, namely, introduction of all-trans-retinoicacid, outcomes have drastically improved, its side effects should not be ignored. Mycosis fungoides is one of the side effects of all-trans-retinoicacid treatment, but it may also be a clinical manifestation before disease progression. However, it rarely appears and is easily overlooked. This leads to being easily misled during the treatment process, affecting the treatment plan, and resulting in adverse consequences. Therefore, early identification and judgment can not only provide appropriate treatment options, but also prevent and treat further disease progression.
PATIENT CONCERNS: The patient was hospitalized for pancytopaenia. After completing the examination, the patient was finally diagnosed with acute promyelocytic leukaemia (acute myelogenous leukaemia-M3). We administered tretinoin and arsenous acid. Evaluation of the treatment effect on the 7th day after chemotherapy showed that the bone marrow morphology showed complete remission. After the second course of chemotherapy, the patient developed red miliary macular papules, which gradually worsened. After completing relevant inspections, Considering that the cases was complicated with skin mycosis fungoides, the patient was treated with budesonide ointment and methylprednisolone as chemotherapy.
DIAGNOSES: Upon examination, the patient was initially diagnosed with acute promyelocytic leukaemia. Evaluation of the treatment effect on the 7th day after chemotherapy showed that the bone marrow morphology showed complete remission. After the second course of chemotherapy, we discovered the patient was diagnosed with skin mycosis fungoides.
INTERVENTIONS: Systemic chemotherapy is first given when a patient was diagnosed with acute promyelocytic leukaemia. After the patient happened skin mycosis fungoides, We have adjusted the treatment plan and supplemented it with other treatment plans based on the original chemotherapy, After 2 months of treatment, his condition gradually improved.
OUTCOMES: All-trans-retinoicacid in the treatment of APL must be given attention because mycosis fungoides should not only be distinguished from infectious diseases but also be further assessed with regard to disease progression and metastasis.
LESSONS: Acute promyelocytic leukemia needs to be treated with arsenic trioxide. All-trans-retinoicacid in the treatment of APL must be given attention mycosis fungoides. Early diagnosis can guide accurate treatment, which is of great help in alleviating the pain of patients and improving the cure rate.

<P>PROBLEM TO BE SOLVED: To provide a process for treating an oil derived from microorganisms.  <P>SOLUTION: This process for treating an oil comprises bringing the oil into contact with a polar solvent to extract at least one compound that is soluble in the solvent, and then separating the solvent containing the compound from the so treated oil. The oil is microbially derived, and extracted either from a fermentation broth or a filtrate thereof using hexane. The compound to be extracted is usually a sterol or a diglyceride. The solvent is ethanol having up to 5% water. The oil can contain a polyunsaturated fatty acid such as 18C, 20C or 22C ω-3 or ω-6 fatty acid, such as arachidonic acid.  <P>COPYRIGHT: (C)2009,JPO&INPIT
OBJECTIVE: To describe the diagnostic and prognostic performance, and longitudinal trajectories, of potential biomarkers of neuroaxonal degeneration and neuroinflammation in amyotrophic lateral sclerosis (ALS).
METHODS: This case-control study included 192 incident ALS patients, 42 ALS mimics, 114 neurological controls, and 117 healthy controls from Stockholm, Sweden. Forty-four ALS patients provided repeated measurements. We assessed biomarkers of (1)neuroaxonal degeneration: neurofilament light (NfL) and phosphorylated neurofilament heavy (pNfH) in cerebrospinal fluid (CSF) and NfL in serum, and (2)neuroinflammation: chitotriosidase-1 (CHIT1) and monocyte chemoattractant protein 1 (MCP-1) in CSF. To evaluate diagnostic performance, we calculated the area under the curve (AUC). To estimate prognostic performance, we applied quantile regression and Cox regression. We used linear regression models with robust standard errors to assess temporal changes over time.
RESULTS: Neurofilaments performed better at differentiating ALS patients from mimics (AUC: pNfH 0.92, CSF NfL 0.86, serum NfL 0.91) than neuroinflammatory biomarkers (AUC: CHIT1 0.71, MCP-1 0.56). Combining biomarkers did not improve diagnostic performance. Similarly, neurofilaments performed better than neuroinflammatory biomarkers at predicting functional decline and survival. The stratified analysis revealed differences according to the site of onset: in bulbar patients, neurofilaments and CHIT1 performed worse at predicting survival and correlations were lower between biomarkers. Finally, in bulbar patients, neurofilaments and CHIT1 increased longitudinally but were stable in spinal patients.
CONCLUSIONS: Biomarkers of neuroaxonal degeneration displayed better diagnostic and prognostic value compared with neuroinflammatory biomarkers. However, in contrast to spinal patients, in bulbar patients neurofilaments and CHIT1 performed worse at predicting survival and seemed to increase over time.
