Benzo[a]pyrene (BaP) and its metabolic end product benzo(a)pyren-7,8-dihydrodiol-9,10-epoxide (BPDE), are known toxic environmental pollutants. This study aimed to analyze whether sub-chronic BPDE exposure initiated pulmonary fibrosis and the potential mechanisms. In this work, male C57BL6/J mice were exposed to BPDE by dynamic inhalation exposure for 8 weeks. Our results indicated that sub-chronic BPDE exposure evoked pulmonary fibrosis and epithelial-mesenchymal transition (EMT) in mice. Both in vivo and in vitro, BPDE exposure promoted nuclear translocation of Snail. Further experiments indicated that nuclear factor erythroid 2-related factor 2 (Nrf2) and p62 were upregulated in BPDE-exposed alveolar epithelial cells. Moreover, Nrf2 siRNA transfection evidently attenuated BPDE-induced p62 upregulation. Besides, p62 shRNA inhibited BPDE-incurred Snail nuclear translocation and EMT. Mechanically, BPDE facilitated physical interaction between p62 and Snail in the nucleus, then repressed Snail protein degradation by p62-dependent autophagy-lysosome pathway, and finally upregulated transcriptional activity of Snail. Additionally, aryl hydrocarbon receptor (AhR) was activated in BPDE-treated alveolar epithelial cells. Dual-luciferase assay indicated activating AhR could bind to Nrf2 gene promoter. Moreover, pretreatment with CH223191 or α-naphthoflavone (α-NF), AhR antagonists, inhibited BPDE-activated Nrf2-p62 signaling, and alleviated BPDE-induced EMT and pulmonary fibrosis in mice. Taken together, AhR-mediated Nrf2-p62 signaling contributes to BaP-induced EMT and pulmonary fibrosis.

Methods for preconditioning and/or providing neuroprotection to the animal central nervous system against the effects of progressive supranuclear palsy. Therapeutic agents are administered to the upper third of the nasal cavity to bypass the blood-brain barrier and access the central nervous system directly to avoid unwanted and potentially lethal side effects. Therapeutic agents include those substances that interact with iron and/or copper such as iron chelators, copper chelators, and antioxidants. A particular example of such therapeutic agents is the iron chelator deferoxamine (DFO). An effective amount of DFO may be administered to the upper third of the nasal cavity of a patient at risk for, or diagnosed with, progressive supranuclear palsy. The effective amount of DFO is delivered directly to the patient's central nervous system for preconditioning, preventing and/or treating the progressive supranuclear palsy.
Head and neck cancer treatment has developed over the last decade, with improved mortality and survival rates, but the treatments often result in dysphagia (a difficulty in swallowing) as a side effect. Swallowing function is affected by the tumor itself, surgical resection of the lesion and neoadjuvant chemoradiation therapy. It is well accepted that pre-treatment swallow function is indicative of post-treatment status and is helpful in identifying patients with high risk of aspiration and dysphagia. In recent years, the concept of "use it, or lose it" has been widely advocated by specialists. Preventive swallowing rehabilitation including evaluation patient's swallowing function and propose rehabilitation and adaptive maneuver or change in food texture. The aim is to ensure safe swallowing and prevent deglutitive muscles from deconditioning. Moreover, aspiration can be prevented and adequate nutrition was maintained through the cancer treatment course. Investigators include patients with advanced oral cavity cancer who were treated by radical operation and free flap reconstruction, and provided them with preventive swallowing rehabilitation. Investigators then analyze the swallowing function, oral intake status, and nasogastric tube dependence rate and tracheostomy tube dependence rate.The participants received interventions as part of our routine medical care, and Investigators studied the effect of the intervention.
Pirfenidone will be administered orally in 267 mg capsules taken with food. The dose will be titrated over 2 weeks from one capsule three times a day during Week 1 to two capsules three times a day during Week 2 then maintenance dose (three capsules three times a day Week 3.
PRP Preparation: 16 ml of blood was obtained from each patient using special PRP kits (GD medical pharma, Dutch company). The blood was collected on citrated tubes with a mixing ratio of 9:1 by volume. Tubes underwent 1st centrifugation at speed of 3000 rpm (704g) for 3 minutes (to separate red blood cells from plasma). Plasma was then removed by syringe and then placed into another sterile tube with no anticoagulant and then underwent 2nd centrifugation at speed of at 4000 rpm (1252g) for 15 min. The supernatant platelet-poor plasma was then removed leaving 2 ml of PRP pellets in the sediment, and suspend the PRP pellets by gentle shaking of the tube. PRP is activated by adding 200 μl of 0.025 calcium chloride(Dhurat and Sukesh, 2014).
BACKGROUND: Metabolic reprogramming and epigenetic alterations contribute to the aggressiveness of pancreatic ductal adenocarcinoma (PDAC). Lactate-dependent histone modification is a new type of histone mark, which links glycolysis metabolite to the epigenetic process of lactylation. However, the role of histone lactylation in PDAC remains unclear.
METHODS: The level of histone lactylation in PDAC was identified by western blot and immunohistochemistry, and its relationship with the overall survival was evaluated using a Kaplan-Meier survival plot. The participation of histone lactylation in the growth and progression of PDAC was confirmed through inhibition of histone lactylation by glycolysis inhibitors or lactate dehydrogenase A (LDHA) knockdown both in vitro and in vivo. The potential writers and erasers of histone lactylation in PDAC were identified by western blot and functional experiments. The potential target genes of H3K18 lactylation (H3K18la) were screened by CUT&Tag and RNA-seq analyses. The candidate target genes TTK protein kinase (TTK) and BUB1 mitotic checkpoint serine/threonine kinase B (BUB1B) were validated through ChIP-qPCR, RT-qPCR and western blot analyses. Next, the effects of these two genes in PDAC were confirmed by knockdown or overexpression. The interaction between TTK and LDHA was identified by Co-IP assay.
RESULTS: Histone lactylation, especially H3K18la level was elevated in PDAC, and the high level of H3K18la was associated with poor prognosis. The suppression of glycolytic activity by different kinds of inhibitors or LDHA knockdown contributed to the anti-tumor effects of PDAC in vitro and in vivo. E1A binding protein p300 (P300) and histone deacetylase 2 were the potential writer and eraser of histone lactylation in PDAC cells, respectively. H3K18la was enriched at the promoters and activated the transcription of mitotic checkpoint regulators TTK and BUB1B. Interestingly, TTK and BUB1B could elevate the expression of P300 which in turn increased glycolysis. Moreover, TTK phosphorylated LDHA at tyrosine 239 (Y239) and activated LDHA, and subsequently upregulated lactate and H3K18la levels.
CONCLUSIONS: The glycolysis-H3K18la-TTK/BUB1B positive feedback loop exacerbates dysfunction in PDAC. These findings delivered a new exploration and significant inter-relationship between lactate metabolic reprogramming and epigenetic regulation, which might pave the way toward novel lactylation treatment strategies in PDAC therapy.
Pentatrichomonas hominis, a flagellated parasitic protozoan, predominantly infects the mammalian digestive tract, often causing symptoms such as abdominal pain and diarrhea. However, studies investigating its pathogenicity are limited, and the mechanisms underlying P. hominis-induced diarrhea remain unclear. Establishing an in vitro cell model for P. hominis infection is imperative. This study investigated the interaction between P. hominis and IPEC-J2 cells and its impact on parasite growth, adhesion, morphology, and cell viability. Co-cultivation of P. hominis with IPEC-J2 cells resulted in exponential growth of the parasite, with peak densities reaching approximately 4.8 × 105 cells/mL and 1.2 × 106 cells/mL at 48 h for initial inoculation concentrations of 104 cells/mL and 105 cells/mL, respectively. The adhesion rate of P. hominis to IPEC-J2 cells reached a maximum of 93.82% and 86.57% at 24 h for initial inoculation concentrations of 104 cells/mL and 105 cells/mL, respectively. Morphological changes in IPEC-J2 cells co-cultivated with P. hominis were observed, manifesting as elongated and irregular shapes. The viability of IPEC-J2 cells exhibited a decreasing trend with increasing P. hominis concentration and co-cultivation time. Additionally, the mRNA expression levels of IL-6, IL-8, and TNF-α were upregulated, whereas those of CAT and CuZn-SOD were downregulated. These findings provide quantitative evidence that P. hominis can promote its growth by adhering to IPEC-J2 cells, inducing morphological changes, reducing cell viability, and triggering inflammatory responses. Further in vivo studies are warranted to confirm these results and enhance our understanding of P. hominis infection.
Status epilepticus (SE) is a neurological emergency that requires timely pharmacological therapy to cease seizure activity. The treatment approach varies based on the time and the treatment stage of SE. Benzodiazepines are considered the first-line therapy during the emergent treatment phase of SE. Antiseizure medicines such as phenytoin, valproic acid, and levetiracetam are recommended during the urgent treatment phase. These drugs appear to have a similar safety and efficacy profile, and individualized therapy should be chosen based on patient characteristics. Midazolam, propofol, pentobarbital, and ketamine are continuous intravenous infusions of anesthetic medications utilized in the refractory SE (RSE) period. The most efficacious pharmacotherapeutic treatments for RSE and superrefractory status epilepticus are not clearly defined.

OBJECTIVES: Adolescent and pediatric functional constipation (FC) is a common clinical problem. Currently, data on lubiprostone for the treatment of pediatric FC are scarce. This study investigated the efficacy and safety of lubiprostone in the treatment of pediatric FC.
METHODS: In a single-blinded, randomized controlled study, we included 280 patients aged 8-18 years with FC. Patients were randomized either to a weight-based lubiprostone dose (n = 140) or conventional laxatives (n = 140), including lactulose, bisacodyl, or sodium picosulfate, for 12 weeks, followed by 4 weeks posttreatment follow-up.
RESULTS: Improvement in constipation was achieved in 128 (91.4%) patients in the lubiprostone group, and in 48 (34.3%) patients of the conventional therapy group (p < 0.001) and was sustained after treatment discontinuation. One quarter of the lubiprostone group experienced the first spontaneous bowel motion within 48 h after dose initiation. A total of 75.7% of the lubiprostone group could achieve and sustain Bristol stool form of 3 or 4 during the last 4 weeks of therapy and through the 4 weeks of follow-up versus 50 (35.7%) patients in the conventional therapy group (p < 0.001). No life-threatening adverse drug reactions were encountered, and no treatment-related discontinuation. Mild self-limited colicky abdominal pain and headache were the most prevalent side effects in the lubiprostone group.
CONCLUSIONS: Lubiprostone is an effective and well-tolerated pharmacotherapy for youthful age and pediatric age groups, which may alter the paradigm of pediatric FC treatment.
People with severe kidney failure need treatment by dialysis or transplantation to stay alive. In the UK there are 25,000 people receiving treatment with haemodialysis (HD). Conventional haemodialysis works on the principle of diffusion for removal of toxins. Haemodiafiltration (HDF) is a technique of dialysis which implies the principle of convection in addition to diffusion. Large clinical trials comparing haemodiafiltration with conventional haemodialysis have reported better survival in patients having haemodiafiltration with large convection volume. The mechanism of survival benefit with high convection volume remains unclear.

The investigators hypothesize that the benefit of high convection volume haemodiafiltration is due to enhanced removal of large sized toxins called 'middle molecules'. Additionally, it may also be due to better blood pressure control and less inflammation when dialysing using this technique. The literature so far has been inconsistent to confirm this. Understanding the relationship of haemodiafiltration convection volume with middle molecules removal and clinical parameters is crucial for adoption of this mode of treatment. Additionally, it can potentially transform the presently imperfect dialysis prescription based on small molecule removal to clinically relevant middle molecules removal.

In this single centre cross sectional study, the investigators aim to recruit 400 adult participants who have been on haemodiafiltration for at least 3 months. Once consented, the participants will be observed in a single routine dialysis sessions (study visit) to record all the standard care clinical parameters and dialysis related information including dialysis convection volume from haemodiafiltration. Participants will also have routine blood tests at the start and end of the observed dialysis session and additional blood tests to measure the removal of middle molecules at the same time. The relationship of these observed clinical and measured toxins removal parameters with convection volume will be determined from the collected data.
BACKGROUND: Mechanical ventilation (MV) is vital for critically ill ICU patients but carries significant mortality risks. This study aims to develop a predictive model to estimate hospital mortality among MV patients, utilizing comprehensive health data to assist ICU physicians with early-stage alerts.
METHODS: We developed a Machine Learning (ML) framework to predict hospital mortality in ICU patients receiving MV. Using the MIMIC-III database, we identified 25,202 eligible patients through ICD-9 codes. We employed backward elimination and the Lasso method, selecting 32 features based on clinical insights and literature. Data preprocessing included eliminating columns with over 90% missing data and using mean imputation for the remaining missing values. To address class imbalance, we used the Synthetic Minority Over-sampling Technique (SMOTE). We evaluated several ML models, including CatBoost, XGBoost, Decision Tree, Random Forest, Support Vector Machine (SVM), K-Nearest Neighbors (KNN), and Logistic Regression, using a 70/30 train-test split. The CatBoost model was chosen for its superior performance in terms of accuracy, precision, recall, F1-score, AUROC metrics, and calibration plots.
RESULTS: The study involved a cohort of 25,202 patients on MV. The CatBoost model attained an AUROC of 0.862, an increase from an initial AUROC of 0.821, which was the best reported in the literature. It also demonstrated an accuracy of 0.789, an F1-score of 0.747, and better calibration, outperforming other models. These improvements are due to systematic feature selection and the robust gradient boosting architecture of CatBoost.
CONCLUSION: The preprocessing methodology significantly reduced the number of relevant features, simplifying computational processes, and identified critical features previously overlooked. Integrating these features and tuning the parameters, our model demonstrated strong generalization to unseen data. This highlights the potential of ML as a crucial tool in ICUs, enhancing resource allocation and providing more personalized interventions for MV patients.

With the development of oncology and immunology in recent years, immunotherapy represents a novel path to obtain a durable and long-lasting response in cancer patients. NK and NKT cells are expanded conventionally from peripheral blood mononuclear cells by addition of a variety of cytokines in vitro culture. Our previous studies demonstrated that the expansion of NK and NKT cells in a clinical usage scale from peripheral blood mononuclear cells is feasible. Those expanded NK and NKT cells exhibit antitumor effect in vitro and in vivo against a variety of tumor cells. The current study proposes a 3-course treatment of doses administered at one week intervals with monitoring at each administration plus 4 weeks after the last dose. The total study time (apheresis through last follow-up) is estimated at 3 year.

Fatal overdosage with pilocarpine has been reported in the scientific literature at doses presumed to be greater than 100 mg in two hospitalized patients. 100 mg of pilocarpine is considered potentially fatal. Overdosage should be treated with atropine titration (0.5 mg to 1.0 mg given subcutaneously or intravenously) and supportive measures to maintain respiration and circulation. Epinephrine (0.3 mg to 1.0 mg, subcutaneously or intramuscularly) may also be of value in the presence of severe cardiovascular depression or bronchoconstriction. It is not known if pilocarpine is dialyzable.
