Creating and evaluating the score to assess overdose: the OD score. BMC Emerg Med 2024; 24:5. [PMID: 38185623 PMCID: PMC10773033 DOI: 10.1186/s12873-023-00923-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2023] [Accepted: 12/21/2023] [Indexed: 01/09/2024] Open
Abstract
BACKGROUND During disasters (including epidemics such as coronavirus disease 2019), the capacity of emergency departments is exceeded, thereby hindering the administration of appropriate lifesaving measures. Furthermore, the number of overdose patients increases because of the stress overload during emergency situation. The fact that overdose patients are forced to be transported to medical facilities that do not typically treat them is becoming worrisome. Moreover, there is no definitive score for overdose. This study aimed to create a patient-specific scoring system to assess overdose. METHODS This was a retrospective single-center study. The evidence-based OD score was evaluated on a scale of 0-15. Further, logistic analysis and receiver operating characteristic (ROC) curve analysis were performed to evaluate the score. RESULTS Overall, 262 patients (including 118 overdose patients) receiving care at the intensive care unit of Japan's Teikyo University Hospital in 2021 were targeted. Regarding the total OD score, ROC analysis revealed a cutoff of 8 (area under the curve [AUC]: 0.99, 95% confidence interval [CI]: 0.980-0.997, sensitivity: 0.95, specificity: 0.95, p < 0.05), which was considered to indicate an overdose. Of the items evaluated in the OD score, the scenario at the location of the patient's discovery (adjusted odds ratio [AOR]: 16.8, 95% CI: 5.0-255.9, p = 0.002) and recent experience of mental anxiety (AOR: 55.7, 95% CI: 2.8-5399.5, p = 0.03) significantly predicted an overdose in multivariable logistic regression analysis. External validation revealed that the OD score could also identify overdose in patients treated in a cohort from 2022 (average cutoff: 8.6, average AUC: 1.0, p < 0.0001). CONCLUSIONS The OD score could accurately assess overdose patients. Medical facilities that do not frequently address overdose patients will benefit from the use of this score.

Abstract
To achieve appropriate blood pressure control in the treatment of hypertension in Japan, this study examined the relationship between office blood pressure and actual antihypertensive drug use in general hospitals following the promulgation of the guidelines for hypertension (JSH2019). This study focused on blood pressure levels and drug use in outpatients on antihypertensive treatment from June to July 2020. The subjects were 2,537 patients classified into four groups based on their medical history, patients with: hypertension only; hypertension and cardiovascular disease; hypertension and dyslipidaemia; and hypertension and diabetes mellitus. The results showed a significant difference in systolic blood pressure (SBP) between patients with hypertension only and those with hypertension and cardiovascular disease (138.3±17.9 mmHg vs 135.6±19.9 mmHg, p<0.05). Regarding actual drug use, it was found that diuretics were prescribed more frequently in patients with hypertension and cardiovascular disease than in those with hypertension alone (15.5% vs 37.9%, p<0.05), even though the number of drugs for hypertension did not differ significantly. In addition, the dose of diuretics was greater only in patients with cardiovascular disease. These results show the actual drug use and blood pressure for each comorbidity. Furthermore, they suggest that the results of antihypertensive treatment may differ by changing the combination and dosage of antihypertensive drugs without changing the number of antihypertensive drugs used. The study also shows the problem of using less diuretics depending on the risk the patient has, and solving the problem may lead to achieving further antihypertensive goals.

Adverse Drug Event Profile Associated with Anti-dementia Drugs: Analysis of a Spontaneous Reporting Database. DIE PHARMAZIE 2023; 78:42-46. [PMID: 37189266 DOI: 10.1691/ph.2023.2584] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Subscribe] [Scholar Register] [Indexed: 05/17/2023]
Abstract
Adverse drug events (ADEs) rates associated with anti-dementia acetylcholinesterase inhibitors are estimated to be 5%-20% and show a wide range of symptoms. No report has examined whether there is a difference in the anti-dementia drugs' ADEs profile. This study aimed to establish whether anti-dementia drugs' ADEs profile differed. Data was based on the Japanese Adverse Drug Event Report (JADER) database. The reporting odds ratios (RORs) was used to analyze data for ADEs from April 2004-October 2021. The target drugs were donepezil, rivastigmine, galantamine, and memantine. The top ten most frequently occurring adverse events were selected. The association between the RORs and antidementia drug ADEs was evaluated, and compared the distribution rate of expression age related to ADEs and each ADEs' timing of onset due to anti-dementia drugs. The primary outcome was RORs. Secondary outcome were expression age and time-to-onset of ADE associated with anti-dementia drugs. A total of 705,294 reports were analyzed. The adverse events incidence differed. Bradycardia, loss of consciousness, falls, and syncope incidence were significantly diverse. The Kaplan-Meier curve results for the cumulative ADEs incidence showed that donepezil had the slowest onset, while galantamine, rivastigmine, and memantine had approximately the same timing of onset.

Abstract
Food-derived peptides have various biological activities. When food proteins are ingested orally, they are digested into peptides by endogenous digestive enzymes and absorbed by the immune cell-rich intestinal tract. However, little is known about the effects of food-derived peptides on the motility of human immune cells. In this study, we aimed to understand the effects of peptides derived from a soybean protein β-conglycinin on the motility of human peripheral polymorphonuclear leukocytes. We illustrated that MITL and MITLAIPVNKPGR, produced by digestion using in-vivo enzymes (trypsin and pancreatic elastase) of β-conglycinin, induces the migration of dibutyryl cAMP (Bt2 cAMP)-differentiated human promyelocytic leukemia 60 (HL-60) cells and human polymorphonuclear leukocytes in a dose- and time-dependent manner. This migration was more pronounced in Bt2 cAMP-differentiated HL-60 cells; mRNA expression of formyl peptide receptor (FPR) 1 increased significantly than in all-trans-retinoic acid (ATRA)-differentiated HL-60 cells. This migration was inhibited by tert-butoxycarbonyl (Boc)-MLP, an inhibitor of FPR, and by pretreatment with pertussis toxin (PTX). However, the effect was weak when treated with WRW4, a selective inhibitor of the FPR2. We then demonstrated that MITLAIPVNKPGR induced intracellular calcium responses in human polymorphonuclear leukocytes and Bt2 cAMP-HL60 cells. Furthermore, pre-treatment by fMLP desensitized the calcium response of MITLAIPVNKPGR in these cells. From the above, MITLAIPVNKPGR and MITL derived from soybean β-conglycinin induced polymorphonuclear leukocyte migration via the FPR1-dependent mechanism. We found chemotactic peptides to human polymorphonuclear leukocytes, which are the endogenous enzyme digests of soybean protein.

Anticholinergic Load Is Associated with Swallowing Dysfunction in Convalescent Older Patients after a Stroke. Nutrients 2022; 14:nu14102121. [PMID: 35631262 PMCID: PMC9143519 DOI: 10.3390/nu14102121] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2022] [Revised: 05/14/2022] [Accepted: 05/17/2022] [Indexed: 02/05/2023] Open
Abstract
This study aimed to establish whether anticholinergic load affects the swallowing function of geriatric stroke patients in convalescent stages, as no proven association between the anticholinergic load-based Anticholinergic Risk Scale and the swallowing dysfunction in Japanese patients was known. A retrospective cohort study was conducted on hospitalized older patients undergoing rehabilitation after stroke. The study outcomes included evaluating the patients at hospital discharge using the Functional Oral Intake Scale. To evaluate the effects of an increased anticholinergic load, we used a multivariate analysis to examine whether the change in the Anticholinergic Risk Scale during hospitalization was associated with the outcome. Of 542 enrolled patients, 345 (63.7%) presented with cerebral infarction, 148 (27.3%) with intracerebral hemorrhage, and 49 (9%) with subarachnoid hemorrhage. The change in the Anticholinergic Risk Scale was independently associated with the Functional Oral Intake Scale (β = −0.118, p = 0.0164) at discharge. Among anticholinergics, the use of chlorpromazine, hydroxyzine, haloperidol, metoclopramide, risperidone, etc., increased significantly from admission to discharge. An increased anticholinergic load was associated with swallowing dysfunction in older patients undergoing stroke rehabilitation.

Abstract
So far, no studies investigated the association between pharmacist intervention and rehabilitation outcomes. The aim of study was to establish whether the pharmacist-led deprescribing intervention affects rehabilitation outcomes. This retrospective, observational, single-center, cohort study included consecutive geriatric patients (n = 448) with pharmacist-led intervention between 2017 and 2019. Participants were divided based on pharmacist-led deprescribing and non deprescribing interventions during hospitalization. Demographic data, laboratory data, the Functional Independence Measure were (FIM) analyzed between the groups. Multiple linear regression analysis was performed to analyze the relationship between pharmacist-led deprescribing and FIM total gain. The primary outcome was FIM total gain. The rate of pharmacist intervention during the study period was 92.4%. A multiple linear regression analysis of FMI-T gain, adjusting for confounding factors, revealed that the pharmacist-led deprescribing intervention was independently correlated with FMI-T gain. Particularly, the use of dyslipidemia drugs, antipsychotic drugs, hypnotics, and nonsteroidal anti-inflammatory drugs significantly decreased during hospitalization. The pharmacist-led deprescribing intervention was independently and significantly associated with FIM-T gain. The pharmacist-led deprescribing intervention improved functional recovery in a rehabilitation setting.

Abstract
LLC-PK1 renal cells show Na+-dependent and Na+-independent hypoxanthine uptake. While the latter is inhibited by adenine, neither are inhibited by xanthine. In rats, intestinal Na+-dependent hypoxanthine transporter Slc23a4 is not expressed in the kidney, and its action is inhibited by xanthine. This study aimed to clone Slc23a4-paralog SLC23A3 from the human kidney and investigate its hypoxanthine transport activity. We observed Na+-dependent 10 nM [3H]-hypoxanthine uptake in SLC23A3 RNA-injected Xenopus oocytes. Moreover, 100 μM xanthine did not inhibit Na+-independent 300 nM [3H]-hypoxanthine uptake, whereas 100 μM adenine did. These results confirm that SLC23A3 is a hypoxanthine transporter in the human kidney.

Abstract
Background Drug overdose accounts for most of the admissions to the emergency department. Prescription drugs, most of which are psychotropic medications, are often misused for drug overdose. The purpose of this study was to investigate the association between overdose in patients transported with disorders of consciousness and psychotropic medications administered prior to transport, so as to enable quick differentiation of drug overdose patients from patients with disorders of consciousness. Methods We evaluated 222 patients transported to the Advanced Critical Care Center of Teikyo University Hospital due to disorders of consciousness. The patients were categorized into two groups: overdose group (n = 128) and control group with other disorders of consciousness (n = 94). Logistic regression models were used to assess the association between disorders of consciousness due to drug overdose and psychotropic drugs prescribed before emergency transportation based on sex and age. Results According to multivariate logistic regression analysis, only female sex (odds ratio [OR] 4.54, 95% confidence interval [CI] 2.43–8.05, P < 0.0001) was associated with overall overdose. Results from the univariate logistic regression analysis showed that in the group of patients aged 40–50 years, female sex (OR 4.36, 95% CI; 1.54–12.4, P = 0.006) and the use of psychotropic drugs (OR 5.05, 95% CI; 1.75–14.6, P = 0.003), benzodiazepines (OR 4.64, 95% CI; 1.61–13.4, P < 0.05), antidepressants (OR 11.4, 95% CI; 2.35–55.8, P = 0.003), and anticonvulsants (OR 4.46, 95% CI; 1.11–17.9, P = 0.035) were associated with overdose. According to multivariate logistic regression analysis, female sex (OR 4.44, 95% CI; 1.37–14.3, P = 0.013) and antidepressants (OR 7.95, 95% CI; 1.21–52.1, P = 0.031) were associated with overdose patients aged 40–50 years. Conclusions As a reference in distinguishing overdose in women in their 40s and 50s who present with impaired consciousness, attention may need to be paid to the type of psychotropic drug used, especially antidepressants.

Abstract
Malnutrition, which commonly occurs in perioperative patients with cancer, leads to decreased muscle mass, hypoalbuminemia, and edema, thereby increasing the patient's risk of various complications. Thus, the nutritional management of perioperative patients with cancer should be focused on to ensure that surgical treatment is safe and effective, postoperative complications are prevented, and mortality is reduced. Pathophysiological and drug-induced factors in elderly patients with cancer are associated with the risk of developing malnutrition. Pathophysiological factors include the effects of tumors, cachexia, and anorexia of aging. Metabolic changes, such as inflammation, excess catabolism, and anabolic resistance in patients with tumor-induced cancer alter the body's ability to use essential nutrients. Drug-induced factors include the side effects of anticancer drugs and polypharmacy. Drug-drug, drug-disease, drug-nutrient, and drug-food interactions can significantly affect the patient's nutritional status. Furthermore, malnutrition may affect pharmacokinetics and pharmacodynamics, potentiate drug effects, and cause side effects. This review outlines polypharmacy and malnutrition, the impact of malnutrition on drug efficacy, drug-nutrient and drug-food interactions, and intervention effects on polypharmacy or cancer cachexia in elderly perioperative patients with cancer.

Abstract
Background Various factors are related to self-management of medication. However, few reports comprehensively examine the factors related to patients, medication levels, and other factors related to the recuperative environment, such as family support. The aim of this study was to investigate factors affecting the continuation of medication self-management among hospitalized older adults receiving convalescent rehabilitation. Methods We conducted a retrospective observational study with 274 consecutive patients newly admitted to the convalescent rehabilitation wards at a single hospital in Japan between January 2017 and May 2018. Participants who were assessed for their ability to take their medication using the Japanese Regimen Adherence Capacity Tests, were deemed to be self-manageable, and were able to successfully continue to self-manage their medication from admission to discharge were categorized as the “continuation group,” and those who were not able to continue were categorized as the “non-continuation group.” We analyzed the groups’ demographic data, laboratory data, and Functional Independence Measure. The primary outcome was the continuation of medication self-management from admission to discharge. Results After enrollment, 134 patients (median age 82 years; 62.7% women) were included in the final analysis. Some 60.4% of eligible patients were able to maintain medication self-management during their hospitalization. The multiple logistic regression analysis for the continuation of medication self-management during hospitalization after adjusting for confounding factors revealed that pharmacist medication instructions were independently and positively correlated with successful continuation of medication self-management (odds ratio: 1.378; 95% confidence interval 1.085–1.831; p = 0.0076). Conclusion Successful continuation of medication self-management is associated with pharmacist medication instructions among hospitalized older adults undergoing rehabilitation. Trail registration The Ethics Committee’s registration number is “TGE01216–066”.

Abstract
Background Polypharmacy or potentially inappropriate medications negatively affect the functional recovery of rehabilitation. However, limited research exists regarding the effect of decreasing in potentially inappropriate medications use on functional improvement of rehabilitation in geriatric Japanese patients. Objective To elucidate whether decreasing PIM during hospitalization could be a predictor of rehabilitation outcomes among geriatric patients in a convalescent rehabilitation setting. Setting This study was conducted at the convalescent rehabilitation ward in the Hitachinaka General Hospital in Japan. Methods This retrospective observational cohort study included consecutive geriatric patients admitted at the convalescent rehabilitation ward between 2010 and 2018. Participants were divided based on presence or absence of decreasing in potentially inappropriate medications use during hospitalization. A multiple linear regression analysis was performed to analyze whether decreasing potentially inappropriate medications use during hospitalization could be a predictor of Functional Independence Measure-Motor at discharge. Main outcome measures The primary outcome was the Functional Independence Measure-Motor at discharge. Results In total, 569 participants (interquartile range 73-85 years; 33.6% men) were included in the present study. A multiple linear regression analysis of Functional Independence Measure-Motor at discharge, adjusting for confounding factors, revealed that decreasing in potentially inappropriate medications use was independently correlated with Functional Independence Measure-Motor at discharge. In particular, the use of first-generation antihistamines, antipsychotics, benzodiazepines, and non-steroidal anti-inflammatory drugs among potentially inappropriate medications decreased significantly during hospitalization. Conclusion Decreased potentially inappropriate medications use during hospitalization may be a predictor of improvement of rehabilitation outcomes in geriatric patients.

Abstract
Cancer patients often suffer from severe pain related to bone metastasis. We encountered a patient in whom the addition of topical non-steroidal anti-inflammatory drugs (NSAIDs) for persistent pain related to bone metastasis during therapy with opioids and oral NSAIDs reduced pain, improving activities of daily living (ADL). Fentanyl patches, celecoxib, denosumab, and topical NSAIDs (loxoprofen tape, felbinac) were administered to a 72-year-old patient with gastric cancer and pain related to bone metastasis. Pain control was favorable, with a numerical rating scale (NRS) score of 2 and Japanese version Support Team Assessment Schedule (STAS-J) score of 1. Intervention by pharmacists for the use of topical NSAIDs decreased both the NRS and STAS-J scores to zero, improving ADL. The results suggest that topical NSAIDs relieve bone-metastasis-related pain, improving ADL. When bone-metastasis-related pain is localized, the prescription of topical NSAIDs should be considered, and positive intervention by pharmacists regarding their usage should be promoted.

Abstract
Background Four-factor prothrombin complex concentrate (4F-PCC) must be administered as soon as possible, and in our emergency intensive care unit (EICU), pharmacists are available on weekdays for consultation on expediting 4F-PCC administration. Although recent reports have described a reduction in time to 4F-PCC administration, few studies have addressed if this is because of EICU pharmacist’s intervention, and there are no such studies in Japan. Therefore, we aimed to examine whether EICU pharmacist’s intervention reduced time to 4F-PCC administration. Methods This single-center retrospective cohort study was conducted from December 2017 to May 2019. We enrolled patients who received 4F-PCC due to major bleeding or requirement of urgent surgical/invasive procedures (n = 10). Patients were divided into two groups, namely, the intervention group (n = 5), in which EICU pharmacists consulted on weekdays, and the nonintervention group (n = 5), in which an intervention was not possible because of the absence of the EICU pharmacist. Results The median time from patient presentation to the EICU to 4F-PCC administration (103 min vs. 111 min, p = 0.4) was similar between the two groups; however, the median time from 4F-PCC prescription ordering to administration was significantly shorter in the intervention group than in the nonintervention group (21 min vs. 60 min, p = 0.02). Conclusions EICU pharmacist’s intervention improves the process from 4F-PCC prescription to administration and can reduce time to 4F-PCC administration.

Abstract
OBJECTIVES The association between anticholinergic load-based Anticholinergic Risk Scale scores and nutritional status is unclear in Japanese patients. The aim of this study was to establish whether anticholinergic load affects the nutritional status of geriatric patients in convalescent stages. DESIGN Retrospective longitudinal cohort study. SETTING Convalescent rehabilitation wards. PARTICIPANTS Of the 1490 patients aged ≥65 years who were discharged from convalescent rehabilitation wards between July 2010 and October 2018, 908 patients met the eligibility criteria. They were categorized according to the presence or absence of increased anticholinergic load from admission to discharge. MEASUREMENTS Demographic data, laboratory data, the Functional Independence Measure were analyzed between the groups. The primary outcome was Geriatric Nutritional Risk Index (GNRI) at discharge. Multiple linear regression analysis was performed to analyze the relationship between anticholinergic load and GNRI at discharge. RESULTS Multiple linear regression analysis after adjusting for confounding factors revealed that anticholinergic load was independently and negatively correlated with GNRI at discharge. Particularly, the use of chlorpromazine, hydroxyzine, haloperidol, metoclopramide, risperidone, etc. increased significantly from admission to discharge. CONCLUSION Increased anticholinergic load during hospitalization may be a predictor of nutritional status in geriatric patients.

Utility and effectiveness of Symbicort® Turbuhaler® (oral inhalation containing budesonide and formoterol) in a patient with severe asthma after permanent tracheostomy. J Pharm Health Care Sci 2018; 4:24. [PMID: 30214819 PMCID: PMC6130086 DOI: 10.1186/s40780-018-0118-y] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2018] [Accepted: 07/04/2018] [Indexed: 11/10/2022] Open
Abstract
Background The utility and effectiveness of inhalational asthma therapy in patients with a permanent tracheostomy has not been established. Previously, a few studies reported the use of nebulizer-type inhalers for treating these patients. Symbicort® Turbuhaler® (Symbicort) is an orally inhaled dry powder containing the corticosteroid budesonide and the bronchodilator formoterol. There are no reports describing the successful use of Symbicort in patients with a permanent tracheostomy. Case presentation We describe the case of a woman with poorly controlled severe asthma after a permanent tracheostomy. She had developed thyroid cancer with tracheal invasion for which right thyroid lobectomy and tracheal and esophageal resection were performed, with subsequent construction of a permanent tracheostomy. In our case, prior to surgery, asthma control had been improved by adding a bronchodilator-the long-acting muscarinic antagonist tiotropium-and the anti-IgE antibody agent omalizumab to single maintenance and reliever therapy (SMART) using Symbicort; surgery was then performed. After surgery, asthma control worsened as a result of a change from Symbicort to budesonide nebulizer and a tulobuterol patch. In order to resume SMART therapy, an In-Check® inspiratory flow meter was used to measure and assess whether the inspiratory flow rate was sufficient for a dry-powder inhaler. Inhalation guidance was provided. On inhalation with the tracheostomy closed at the same time, the inspiratory flow rate was 43 L/min at the maximum. This was judged to be sufficient for the effect of Symbicort, and thus the inhaler was changed to Symbicort. Asthma symptoms promptly improved, and the patient was subsequently discharged. Conclusions The use of Symbicort resulted in improved asthma control in a patient with severe asthma following a permanent tracheostomy. Thus, it is suggested that inhalation powder could be an option for patients with permanent tracheostomy.

[PMID: 29054458 DOI: 10.1016/j.jiac.2017.09.005] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2017] [Revised: 08/28/2017] [Accepted: 09/08/2017] [Indexed: 11/25/2022]
Abstract
The purpose of this study was to estimate the in vivo pharmacokinetics of meropenem during intermittent-infusion hemodiafiltration (I-HDF) and clarify its optimal dosage and dosing interval in patients receiving I-HDF. The clearance of meropenem by online hemodiafiltration (OL-HDF) and I-HDF was predicted using an in vitro system and assessed to establish whether the results obtained are applicable to clinical cases. In the in vivo study, the mean volume of distribution (Vd), non-I-HDF clearance (CLnon-I-HDF), and I-HDF clearance (CLI-HDF) were 15.80 ± 3.59 l, 1.05 ± 0.27 l/h, and 5.78 ± 1.03 l/h. Dosing regimens of 0.25 g once daily for a MIC of 8 μg/ml and of 0.5 g once daily for a MIC of 16 μg/ml achieved 40% T > MIC. In the in vitro and in vivo studies, observed CLHDF was similar to predictive CLHDF (= Cf/Cp × (QD + QSUB)). In conclusion, adjustments to the dose and interval of meropenem were developed based on the presumed susceptibility of pathogens to meropenem in patients receiving I-HDF. We suggest 0.5 g once daily as an appropriate regimen for empirical treatment.

Treatment sequence in castration-resistant prostate cancer: A retrospective study in the new anti-androgen era. Mol Clin Oncol 2017; 7:601-603. [PMID: 28855993 DOI: 10.3892/mco.2017.1361] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2017] [Accepted: 05/16/2017] [Indexed: 01/07/2023] Open
Abstract
In recent years, abiraterone acetate (AA) and enzalutamide (EZL) have become available for the treatment of cancer. Prior clinical trials have demonstrated the benefits of these agents in males with castration-resistant prostate cancer (CRPC). The optimal sequencing of available therapies in the context of efficacy and known cross-resistance remains uncertain. Based on the mechanisms of action and accessible clinical data, AA and EZL may be indicated for the early stages of prostate cancer. Until clinical trials are conducted to determine the best treatment sequence, individualized therapy is required for each patient based on the clinicopathological characteristics. In the present study, 46 sequential patients (median age: 77, range 59-89; median serum PSA level: 56 ng/ml, range 1.5-3,211) with CRPC treated with EZL (160 mg/day) were retrospectively analyzed between June 2014 and July 2015 at the following institutions: Yamagata Prefectural Central Hospital (Yamagata, Japan); Yamagata Tokushukai Hospital (Yamagata, Japan); Ishinomaki Red Cross Hospital (Ishinomaki, Japan); Kan-etsu Hospital (Tsurugashima, Japan); Niigata Cancer Center Hospital (Niigata, Japan); Sakado Central Hospital (Sakado, Japan). A total of 18 patients were pre-treated with Docetaxel (DOC) and 28 patients were DOC-naïve. Once EZL therapy was initiated, increases in prostate specific antigen (PSA) levels were observed in 3/18 patients (17%) pre-treated with DOC and in 6/20 (30%) who were DOC-naïve. In total, 8/28 DOC-naïve patients were treated with AA without EZL. An increase in the PSA level was observed in only 1/8 (12%) cases following AA treatment in the DOC-naïve group. It was demonstrated that AA had a better efficacy in DOC-naïve patients. The efficacy of EZL was limited in AA-pre-treated patients following DOC administration.

Predictors of the therapeutic effect of sivelestat in patients with acute lung injury associated with systemic inflammatory response syndrome. J Pharm Health Care Sci 2016; 2:19. [PMID: 27559479 PMCID: PMC4995800 DOI: 10.1186/s40780-016-0051-x] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2016] [Accepted: 07/01/2016] [Indexed: 11/10/2022] Open
Abstract
Background Sivelestat, a neutrophil elastase inhibitor, was previously approved in Japan for the treatment of acute lung injury associated with systemic inflammatory response syndrome. However, sivelestat produced inconsistent therapeutic benefits. This study aimed to identify factors predicting the therapeutic effects of sivelestat. Methods We enrolled 53 mechanically ventilated patients who received sivelestat. The patients were classified as effective (n = 28) if they were weaned from the ventilator within 28 days, or as ineffective groups (n = 25). Patient characteristics were compared between these groups and multivariate logistic regression analysis was used to identify predictive factors. A validation study was then conducted in sivelestat-free patients. Results A high red blood cell count and low hydrogen ion concentration were significantly associated with a higher ventilator weaning rate in patients receiving sivelestat. The validation study revealed that the hydrogen ion concentration value also significantly associated with ventilator weaning in patients who did not receive sivelestat. Conclusions Although hydrogen ion concentration was inversely associated with the ventilator weaning rate, it did not predict sivelestat efficacy. This study indicated that acute lung injury patients with a high red blood cell count would derive the most benefit from sivelestat administration.

Abstract
Thymidylate synthase (TS), a key enzyme in DNA synthesis, is over-expressed in a variety of cancer cells. 5-Fluorouracil, an anticancer agent clinically used against various cancers, including prostate cancer, inhibits DNA synthesis by binding TS. In this study, we investigated expression of TS in prostate cancer and its prognostic significance. Seventy-five prostatic tissue specimens were obtained from patients who had undergone prostate biopsy for diagnosis of prostate cancer. We analyzed the cancerous tissue specimens for TS expression using immunohistochemistry. TS expression was significantly increased in patients with bone metastasis. No relationship was found between expression of TS and the other clinicopathological findings. Because TS expression could be used as a prognostic parameter in patients with prostate cancer, an accurate prediction of prognosis might help to select patients for more intensive surgical, hormonal, or chemotherapeutic approaches, including 5-fluorouracil. Additional prospective studies are warranted to define the role of TS in selecting patients for adjuvant therapy for prostate cancer.

Abstract
We report a case of primary undifferentiated bladder carcinoma, which revealed a remarkable response to methotrexate, vinblastine, adriamycin, and cisplatin (MVAC) therapy. A 46-year-old Japanese woman presented at the hospital with the chief complaints of gross hematuria and pain during urination. Cystoscopy revealed a large smooth-surfaced tumor in the urinary bladder. The histopathological diagnosis was undifferentiated carcinoma. The patient then received 3 courses of MVAC over a 3-month period. Hydronephrosis disappeared after the first course, and the tumor shrank rapidly. After completion of the third MVAC course, radical cystectomy and ileal conduit surgery were performed. After 7 years, the patient has still had no recurrences or metastases. We retrospectively review the relative efficacy of the two popular chemotherapeutic regimens in the management of muscle-invasive bladder cancer in patients who had had radical cystectomy.

Abstract
Several clinically approved recombinant erythropoietin (rEPO) preparations, such as epoetin-β, epoetin-δ and the epoetin-α derivative, darbepoetin-α, have been commercially produced. Since the expiration of patent protection, a number of novel rEPO biosimilars have been approved on the world market. In 2010, epoetin-κ, which is biosimilar to epoetin-α, was clinically approved. Epoetin-κ is a biopharmaceutical product that is based on serum-free media following master cell bank preparation. The present study analyzes the results obtained during a six-month observation period, in which the administration of epoetin-β was switched to that of epoetin-κ. In a cohort of patients receiving chronic dialysis, who were clinically in a state of relative calm and were in control of their renal anemia, it was possible to sustain good control of the anemia by reducing the frequency of the epoetin-β administration from the conventional and empirically determined three times a week to twice a week, and further to once a week. Furthermore, the good control was maintained upon changing from the administration of epoetin-β to that of epoetin-κ. Moreover, three months subsequent to this switch, the degree of instability observed among the patients had decreased. Despite the fact that the situation following the changeover requires further investigation, it may be concluded that the results obtained in this study are indicative of the clinical equivalence and efficacy of epoetin-κ.

Solid dispersion of spironolactone with porous silica prepared by the solvent method. DIE PHARMAZIE 2007; 62:599-603. [PMID: 17867555] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 05/17/2023]
Abstract
Solid dispersions of spironolactone (SPI) with porous silica (Sylysia 730 and Sylysia 350) were prepared by the solvent method. The physicochemical properties of the prepared solid dispersions were evaluated by powder X-ray diffractometry (PXRD), differential scanning calorimetry (DSC), scanning electron microscopy (SEM), and atomic force microscopy (AFM). In the SEM study, no differences in the surface condition between Sylysia 350 and the solid dispersion of a Sylysia 350:SPI system in a weight ratio of 1:1 were observed. However, AFM phase images showed that the surface of the solid dispersion of the Sylysia 350:SPI system (weight ratio of 1:1) was rather smooth due to the adsorption of SPI as compared with that of a Sylysia 350 intact. The results of PXRD and DSC data in the solid dispersion of the Sylysia 350:SPI system (weight ratio of 1:1) indicated that the molecular state of the adsorbed SPI changed from crystalline to amorphous. Although the decrease in the SPI concentration increased with the amorphous fraction in the solid dispersion, the diffraction peaks due to SPI crystals still remained in the solid dispersion of a Sylysia 730:SPI system (weight ratio of 1:1), indicating that the mean pore diameter and specific surface area of an additive are some of the important factors for the amorphization of SPI crystals. The dissolution property of the SPI from the solid dispersions was remarkably improved in comparison with that of SPI crystals. The dissolution rate of the SPI from the solid dispersions with Sylysia 350 was faster than that of the SPI from the solid dispersions with Sylysia 730. The difference in the dissolution properties of SPI from both the solid dispersions was attributed to the difference in the molecular state of the SPI in both the solid dispersions. In the stability test, the amorphous state of the SPI in the solid dispersion of the Sylysia 350:SPI system (weight ratio of 1:1) was maintained for 2 weeks at 25 degrees C and 0% RH, while the amorphous SPI without Sylysia 350 crystallized under the same conditions.

Abstract
Questionnaires were sent out to the staffs (13 physicians, 52 nurses and 5 medical engineers) of the ICU/CCU at the University of Tokyo Hospital, to evaluate pharmaceutical services by analyzing problems in the services offered. Four components of pharmaceutical services were evaluated: inventory control of drugs, check of drug usage and doses, mixing of injections, and offering drug information. Almost all responses from medical staffs evaluated pharmaceutical services overall as "good". The high response rate (96%) from the nursing staff was attributed to the fact that they were familiar with the pharmacist's role with drug inventory, and mixing injections, when nursing was not available for these tasks. Although 50% of physicians rated the pharmaceutical services of providing drug information as "good", this value was lower than responses on other items of the questionnaires, which suggests some dissatisfaction. The occurrences of drug information obtained by passive offering (121 subjects) was 4 times as common as drug information obtained by active offering (30 subjects). From this finding, and comments on the questionnaires from physicians, it suggests that physicians require more drug information for dosage regimens, and prefer the drug information to be provided more actively. Further, an important comment from physicians and nurses was that the services of pharmacists are not available on all shifts/all days of the week to provide consultation for drug information and mixing of injections. Although having a pharmacist available daily around the clock is desirable and ideal to the medical team, the number of pharmacists under the present system cannot support this. As a solution, we think that it is crucial that pharmacists educate medical staff when they are present to in order to optimize therapy and patient care over time.

Abstract
We previously reported the development and clinical efficacy of a 2% aspirin oral ointment and 2% ethenzamide oral ointment as hospital preparations for painful lesions of the oral mucosa. This study investigated methods of preparing a more stable oral ointment with a more effective analgesic action, using diflunisal, another salicylic acid derivative, with an analgesic effect stronger than that of aspirin. A two-percent diflunisal oral ointment was prepared similarly to the aspirin ointment using plastibase and CMC-Na as the ointment base. From the results of spreadability measurement, a CMC-Na content of 20% was considered appropriate. The stability of diflunisal in 2% diflunisal oral ointment stored at 5 degrees C, 20 degrees C and 30 degrees C, was determined using HPLC, and a high stability of diflunisal at room temperature for more than 100 days was confirmed. We also investigated its antinociceptive effect using the Randall-Selitto paw pressure test in rats, which showed that 2% diflunisal oral ointment was as effective as 2% aspirin oral ointment. On clinical application of 2% diflunisal oral ointment to 8 patients with painful oral mucous diseases, it was found to be significantly (p = 0.014) more effective than 2% aspirin oral ointment. The results of this study demonstrated that 2% diflunisal oral ointment is a clinically useful analgesic for painful oral lesions.

Abstract
A high performance liquid chromatography (HPLC) method has been developed for the simultaneous determination of plasma levels of theophylline and its metabolites without interference from caffeine or caffeine metabolites. The method is simple and of practical use because it is applicable even to plasma samples from patients who take caffeine-containing beverages. The method was also reproducible with a coefficient of variation of less than 5% for each analyte. The levels of theophylline, determined by HPLC, were validated by their high correlation to the levels obtained by fluorescence polarization immunoassay. HPLC was used to determine theophylline levels in patients with bronchial asthma. The data revealed that the ratio of 1,3-dimethyluric acid, the major metabolite of theophylline, to theophylline concentration in the plasma was within a narrow range in most patients (0.055 +/- 0.01, n = 66), regardless of the method of theophylline administration or the time of blood sampling. Conversely, this ratio was as low as 0.027 +/- 0.005 in the patient with a long plasma half-life of theophylline. These results suggest that it may be possible to predict the plasma half-life of theophylline for each patient from a single blood sample. This may be useful when planning theophylline administration, especially in patients with abnormal theophylline metabolism.
