Mantle cell lymphoma (MCL) presenting in elderly, unfit patients represents a clin. challenge. Front-line attenuated or low-intensity immunochemotherapy is often employed, although outcomes are relatively unexplored. We report outcomes of attenuated immunochemotherapy in 95 patients with MCL across 19 centers in the UK and Ireland considered unfit for full-dose rituximab-bendamustine or rituximab-cyclophosphamide, doxorubicin, vincristine, prednisolone (R-CHOP). Regimens examined were rituximab-cyclophosphamide, vincristine, prednisolone (R-CVP) (n = 19), dose-attenuated R-CHOP (n = 22), dose attenuated rituximab-bendamustine (n = 24) and rituximab-chlorambucil (n = 30). The primary outcome was progression-free survival (PFS). The secondary outcomes included overall response, overall survival (OS) and toxicity. The median (range) age was 79 (58-89) years and 50% were aged ≥80 years. The median (range) Cumulative Illness Rating Scale-Geriatric score was 6 (0-24). The median PFS for all patients was 15 mo 95% confidence interval (CI) (8·7-21·2) and median OS was 31·4 mo (95% CI 19·7-43·2). By multivariable anal. (MVA), the only clin. factor associated with an inferior PFS was blastoid morphol. hazard ratio (HR) 2·90, P = 0·01. Notably, higher treatment intensity (R-CHOP/R-bendamustine composite) provided an independently superior PFS compared with R-CVP/R-chlorambucil (MVA HR 0·49, P = 0·02). Factors associated with inferior OS by MVA were Eastern Cooperative Oncol. Group Performance Status (HR 2·14, P = 0·04), blastoid morphol. (HR 4·08, P = 0·001) and progression of disease at <24 mo status (HR 5·68, P < 0·001). Overall, survival after front-line dose-attenuated immunochemotherapy is unsatisfactory. Clin. trials investigating novel agents such as Bruton tyrosine kinase and B-cell lymphoma 2 inhibitors in this specific clin. setting are warranted. This study involved multiple reactions and reactants, such as 4-(5-(Bis(2-chloroethyl)amino)-1-methyl-1H-benzo[d]imidazol-2-yl)butanoic acid (cas: 16506-27-7SDS of cas: 16506-27-7).

Detection of overdose and underdose prescriptions-An unsupervised machine learning approach was written by Nagata, Kenichiro;Tsuji, Toshikazu;Suetsugu, Kimitaka;Muraoka, Kayoko;Watanabe, Hiroyuki;Kanaya, Akiko;Egashira, Nobuaki;Ieiri, Ichiro. And the article was included in PLoS One in 2021.Formula: C18H20N3NaO3S The following contents are mentioned in the article:

Overdose prescription errors sometimes cause serious life-threatening adverse drug events, while underdose errors lead to diminished therapeutic effects. Therefore, it is important to detect and prevent these errors. In the present study, we used the one-class support vector machine (OCSVM), one of the most common unsupervised machine learning algorithms for anomaly detection, to identify overdose and underdose prescriptions. We extracted prescription data from electronic health records in Kyushu University Hospital between Jan. 1, 2014 and Dec. 31, 2019. We constructed an OCSVM model for each of the 21 candidate drugs using three features: age, weight, and dose. Clin. overdose and underdose prescriptions, which were identified and rectified by pharmacists before administration, were collected. Synthetic overdose and underdose prescriptions were created using the maximum and min. doses, defined by drug labels or the UpToDate database. We applied these prescription data to the OCSVM model and evaluated its detection performance. We also performed comparative anal. with other unsupervised outlier detection algorithms (local outlier factor, isolation forest, and robust covariance). Twenty-seven out of 31 clin. overdose and underdose prescriptions (87.1%) were detected as abnormal by the model. The constructed OCSVM models showed high performance for detecting synthetic overdose prescriptions (precision 0.986, recall 0.964, and F-measure 0.973) and synthetic underdose prescriptions (precision 0.980, recall 0.794, and F-measure 0.839). In comparative anal., OCSVM showed the best performance. Our models detected the majority of clin. overdose and underdose prescriptions and demonstrated high performance in synthetic data anal. OCSVM models, constructed using features such as age, weight, and dose, are useful for detecting overdose and underdose prescriptions.

Background and Aim : Most consensuses recommend culture-guided therapy as third-line Helicobacter pylori treatment. This study aimed to investigate the efficacies of culture-guided therapy and empirical therapy with high-dose proton pump inhibitor (PPI) in the H. pylori third-line treatment. Methods : Between August 2012 and Oct. 2021, H. pylori -infected patients with at least two failed eradication attempts received anti- H. pylori therapy according to the results of antimicrobial sensitivity tests plus high-dose rabeprazole and/or bismuth. They were categorized into three groups: patients who had pos. results of culture with equal to or more than three susceptible antibiotics were treated by culture-guided non-bismuth quadruple therapy, patients who had pos. results of culture with one or two susceptible antibiotics were treated by culture-guided bismuth-containing therapy, and patients who had a neg. result of culture were treated by an empirical therapy with high-dose rabeprazole plus amoxicillin, tetracycline and levofloxacin. A post-treatment assessment was conducted at week 8. Results : We recruited 126 patients. The eradication rates of culture-guided non-bismuth quadruple therapy (n = 50), culture-guided bismuth-containing therapy (n = 46) and empirical therapy (n = 30) were 84.0%, 87.0%, and 66.7% (95% confidence interval: 73.8-94.2%, 77.3-96.7%, and 49.8-83.6%), resp. Overall, culture-guided therapy achieved a higher eradication rate than empirical therapy (85.4% vs 66.7%; 95% confidence interval, 0.4% to 37.0%, P = 0.022). Conclusions : Culture-guided therapy with high-dose PPI achieves a higher eradication rate than empirical therapy with high-dose PPI in the third-line treatment of H. pylori infection. The eradication rate of rescue therapy with bismuth plus two susceptible antibiotics is not inferior to that with three susceptible antibiotics. This study involved multiple reactions and reactants, such as Sodium 2-(((4-(3-methoxypropoxy)-3-methylpyridin-2-yl)methyl)sulfinyl)benzo[d]imidazol-1-ide (cas: 117976-90-6Name: Sodium 2-(((4-(3-methoxypropoxy)-3-methylpyridin-2-yl)methyl)sulfinyl)benzo[d]imidazol-1-ide).

Rabeprazole intake does not affect systemic exposure to capecitabine and its metabolites, 5-deoxy-5-fluorocytidine, 5-deoxy-5-fluorouridine, and 5-fluorouracil was written by Sekido, Masae;Fujita, Ken-ichi;Kubota, Yutaro;Ishida, Hiroo;Takahashi, Takehiro;Ohkuma, Ryotaro;Tsunoda, Takuya;Ishikawa, Fumihiro;Shibanuma, Motoko;Sasaki, Yasutsuna. And the article was included in Cancer Chemotherapy and Pharmacology in 2019.HPLC of Formula: 117976-90-6 The following contents are mentioned in the article:

Purpose: Several retrospective studies have shown that the antitumor efficacy of capecitabine-containing chemotherapy decreases when co-administered with a proton pump inhibitor (PPI). Although a reduction in capecitabine absorption by PPIs was proposed as the underlying mechanism, the effects of PPIs on capecitabine pharmacokinetics remain unclear. We prospectively examined the effects of rabeprazole on the pharmacokinetics of capecitabine and its metabolites. Methods: We enrolled patients administered adjuvant capecitabine plus oxaliplatin (CapeOX) for postoperative colorectal cancer (CRC) patients and metastatic CRC patients receiving CapeOX with/without bevacizumab. Patients receiving a PPI before registration were allocated to the rabeprazole group, and the PPI was changed to rabeprazole (20 mg/day) at least 1 wk before the initiation of capecitabine treatment. On day 1, oral capecitabine (1000 mg/m2) was administered 1 h after rabeprazole intake. Oxaliplatin (and bevacizumab) administration on day 1 was shifted to day 2 for pharmacokinetic anal. of the first capecitabine dose. Plasma concentrations of capecitabine, 5-deoxy-5-fluorocytidine, 5-deoxy-5-fluorouridine, and 5-fluorouracil were analyzed by high-performance liquid chromatog. Effects of rabeprazole on inhibition of cell proliferation by each capecitabine metabolite were examined with colon cancer cells (COLO205 and HCT116). Results: Five and 9 patients enrolled between Sept. 2017 and July 2018 were allocated to rabeprazole and control groups, resp. No significant effects of rabeprazole on area under the plasma concentration-time curve divided by capecitabine dose for capecitabine and its three metabolites were observed Rabeprazole did not affect the proliferation inhibition of colon cancer cells by the resp. capecitabine metabolites. Conclusion: Rabeprazole does not affect capecitabine pharmacokinetics.

Developmental and Epileptic Encephalopathy (DEE) is a group of disorders affecting children at early stages of infancy, which is characterized by frequent seizures, epileptiform activity on EEG, and developmental delayor regression. Developmental and epileptic encephalopathy-30 (DEE30) is a severe neurol. disorder characterized by onset of refractory seizures soon after birth or in the first months of life. Which was recently found to be caused by heterozygous mutations in the salt-inducible kinase SIK1. In this study, we investigated a patient with early onset epilepsy. DNA sequencing of the whole coding region revealed a de novel heterozygous nucleotide substitution (c.880G > A) causing a missense mutation (p.A294T). This mutation was classified as variant of unknown significance (VUS) by American College of Medical Genetics and Genomics (ACMG). To further investigate the pathogenicity and pathogenesis of this mutation, we established a human neuroblastoma cell line (SH-SY5Y) stably-expressing wild type SIK1 and A294T mutant, and compared the transcriptome and metabolomics profiles. We presented a pediatric patient suffering from infantile onset epilepsy. Early EEG showed a boundary dysfunction of activity and MRI scan of the brain was normal. The patient responded well to single anti-epileptic drug treatment. Whole-exome sequencing found a missense mutation of SIK1 gene (c.880G > A chr21: 43,420,326 p. A294T). Dysregulated transcriptome and metabolome in cell models expressing WT and MUT SIK1 confirmed the pathogenicity of the mutation. Specifically, we found MEF2C target genes, certain epilepsy causing genes and metabolites are dysregulated by SIK1 mutation. We found MEF2C target genes, certain epilepsy causing genes and metabolites are dysregulated by SIK1 mutation.

Rabeprazole has efficacy per se and reduces resistance to temozolomide in glioma via EMT inhibition was written by Babu, Deepak;Mudiraj, Anwita;Yadav, Neera;Y. B. V.

Epithelial to mesenchymal transition (EMT) is pivotal in embryonic development and wound healing, whereas in cancer it inflicts malignancy and drug resistance. The recognition of an EMT-like process in glioma is relatively new and its clin. and therapeutic significance has, as yet, not been fully elucidated. Here, we aimed to delineate the clin. significance of the EMT-like process in glioma and its therapeutic relevance to rabeprazole. We investigated the expression profiles of EMT-associated proteins in primary glioma biopsies through Western blotting and immunohistochem., and correlated them with various clinicopathol. features and data listed in the cancer genome atlas (TCGA). In addition, the anticancer efficacy of rabeprazole and its therapeutic relevance to EMT along with temozolomide chemo-sensitization were assessed using multiple cell-based assays, Western blotting and confocal imaging. For in vivo assessment, we used a stereotaxic C6-rat glioma model. Expression anal. of EMT-associated proteins in glioma biopsies, in conjunction with clinicopathol. and TCGA dataset analyses, revealed non-canonical expression of E/N-cadherin and upregulation of GFAP, vimentin and β-catenin. The increased expression of EMT-associated proteins may attribute to glioma malignancy and a poor patient prognosis. Subsequent in vitro studies revealed that rabeprazole treatment attenuated glioma cell growth and migration, and induced apoptosis. Rabeprazole suppressed EMT by impeding AKT/GSK3β phosphorylation and/or NF-κB signaling and sensitized temozolomide resistance. Addnl. in vivo studies showed restricted tumor growth and inhibited expression of EMT-associated proteins after rabeprazole treatment. Our data revealed (i) a clin. association of the EMT-like process with glioma malignancy and a poor survival and (ii) an anticancer and temozolomide sensitizing effect of rabeprazole by repressing EMT.

Healthcare workers can be exposed to dangerous drugs during their daily practice. The National Institute for Occupational Safety and Health (NIOSH) considers “hazardous drugs” as those that had shown one or more of the following characteristic in studies with animals, humans or in vitro systems: carcinogenicity, teratogenicity or other toxicity for development, reproductive toxicity, organ toxicity at low doses, or genotoxicity. In the actual list (draft list 2020), drugs classified in group 1 are those with carcinogenic effects. Moreover, the global human and veterinary cancer is expected to grow, so antineoplastic drug consumption may consequently grow, leading to an increase of anticancer pharmaceuticals in the environment. Not all drugs pertaining to group 1 can be classified as “antineoplastic” or “cytostatic”. Since most of the research on environment presence and ecotoxicol. effects of pharmaceuticals was focused on this therapeutic class, other carcinogenic drugs belonging to different therapeutic groups may were omitted in previous studies. In this study we aim to review the presence in the environment of the hazardous drugs (NIOSH group 1) and their possible environmental impact. Of the 90 drugs considered, there is evidence of presence in the environment for 19. Drugs with more studies reporting pos. detections are: the antibiotic chloramphenicol (55), the alkylating agents cyclophosphamide (39) and ifosfamide (30), and the estrogen receptor modulator tamoxifen (18). Although the original purpose of the NIOSH list and related documents is to provide guidance to healthcare professionals to adequately protect them from the hazards posed by these drugs in healthcare settings, we believe they can be useful for environmentalists too. Absence of data regarding the potential of environmental risk of certain hazardous drugs might tell us which drugs ought to be prioritized in the future.

For patients with gastro-oesophageal reflux symptoms, the preferred treatment is proton pump inhibitor (PPI) administration for approx. 8 wk. However, long-term use of PPIs can cause gut microbiome (GM) disturbances. This study is designed to evaluate the effect of probiotics combined with a PPI on the GM and gastrointestinal symptoms of patients with gastro-oesophageal reflux disease (GERD). This is a randomized, double-blind, placebo-controlled trial. A total of 120 eligible patients with GERD will be randomized into the exptl. group or the control group. The treatment includes two phases: the initial treatment period lasts 8 wk (weeks 1-8), and the maintenance treatment period lasts 4 wk (weeks 9-12). During the initial treatment period, the exptl. group will take rabeprazole and LiHuo probiotics, and the control group will take rabeprazole and a probiotic placebo; during the maintenance treatment period, the exptl. group will take LiHuo probiotics, and the control group will take a probiotic placebo. The primary measure is the change in the GM. The secondary measures are the Reflux Disease Questionnaire (RDQ) score, Gastrointestinal Symptom Rating Scale (GSRS) score, faecal metabolome (FM), body mass index, Los Angeles grade of oesophagitis, adverse event (AE) rate and treatment compliance. Each outcome indicator will be assessed at day 0 (before administration), day 28 and/or 56 (during administration), and day 84 (end of administration) to reveal intragroup differences. AEs will be monitored to assess the safety of LiHuo probiotics. This will be the first trial to use the intestinal flora metagene method to analyze the effects of probiotics on patients with GERD receiving long-term PPI treatment. The goal is to provide evidence for the use of probiotics to reduce intestinal flora disorders and other symptoms of gastrointestinal discomfort in patients with GERD who have used PPIs for a long period.

Background : Antibiotic resistance emerges as a major issue for Helicobacter pylori (H. pylori) treatment. High-dose dual therapy has recently shown encouraging results in H. pylori eradication, but it has yet to be validated in this H. pylori highly infected area; it is also not known if this concept can be extended to antibiotics other than amoxicillin, and factors that affect the eradication. We investigate if rabeprazole plus amoxicillin or furazolidone regimens could be a first-line therapy for H. pylori eradication, and factors that affect the curing rate. Methods : This is a single-center, prospective, open-label, randomized-controlled trial. Naive patients (n=292) were randomly treated with bismuth-containing quadruple therapy (BQT), rabeprazole plus amoxicillin (RADT), or furazolidone (RFDT) groups. RADT and FADT use three times daily regimens. H. pylori diagnosis and eradication were determined and confirmed by ¹³C-urea breath test. Results : In per-protocol (PP) anal., H. pylori eradication rate was 91.2in BQT group, 89.6in RADT, and 51.0in RFDT group. In intention-to-treat (ITT) anal., infection was eradicated in 86.7of patients in BQT group, 85.8in RADT, and 48.1in RFDT groups, resp. Noninferiority was confirmed between BQT and RADT groups. The incidence of side effects in BQT group was significantly higher than that in RADT group. Successful eradication was associated with lower body surface area (BSA) and low body mass index (BMI) in BQT group. Smoking and high BSA index reduced H. pylori eradication rate in RADT group. Conclusions : Rabeprazole-amoxicillin dual therapy is equally effective to the bismuth-containing quadruple therapy for H. pylori eradication with fewer side effects and saves use of one antibiotic per each treatment. Successful eradication is also associated with low BSA and non-smoking condition, which deserves future stratified anal. for refinement and optimization. This study involved multiple reactions and reactants, such as Sodium 2-(((4-(3-methoxypropoxy)-3-methylpyridin-2-yl)methyl)sulfinyl)benzo[d]imidazol-1-ide (cas: 117976-90-6Formula: C18H20N3NaO3S).

Sodium 2-(((4-(3-methoxypropoxy)-3-methylpyridin-2-yl)methyl)sulfinyl)benzo[d]imidazol-1-ide (cas: 117976-90-6) belongs to imidazole derivatives. Among the different heterocyclic compounds, imidazole is better known due to its broad range of chemical and biological properties. Imidazole has become an important synthon in the development of new drugs. Imidazole also acts as a microtubule destabilizing agents and inhibits topoisomerase and Cytochrome P450 Family 26 Subfamily A Member 1 (CYP26A1) enzymes.Formula: C18H20N3NaO3S
