RESUMO
OBJECTIVE: Cisplatin(CDDP)is a key drug for head and neck cancer therapy, but frequently induces severe adverse events including renal dysfunction. Nedaplatin(CDGP)was developed and is used in Japan; it has certain benefits over CDDP. Unlike CDDP, CDGP treatment does not require hydration. However, CDGP is not used globally and thus safety information is lacking. Therefore, we surveyed safety profiles for CDGP-based chemotherapy. METHODS: A survey was conducted at Showa University Hospital. Thirty-eight patients treated for head and neck cancer combined with radiotherapy(RTx)and tegafur- gimeracil-oteracil(S-1)between April 2012 and March 2015 were included. Laboratory-based adverse events(WBC, Hb, platelet[Plt], SCr, Alb)and oral mucositis were assessed according to CTCAE v5.0. Time-onset profiles for adverse events were evaluated after starting chemoradiotherapy. RESULTS: In 38 patients, Plt nadir was observed following 40(30-70)Gy and sustained for 14(7-35)days. WBC patterns followed similar profiles, but for Hb, nadir was observed following 60(40- 70)Gy and was less frequently sustained throughout the RTx. Alb and SCr levels were not correlated with therapy. Oral mucositis was observed following 50(10-70)Gy. CONCLUSION: In conclusion, at approximately 40 Gy, we observed decreases in WBC and Plt, with an increase in oral mucositis. Based on these results, medical staffs must closely monitor patients, especially at doses within range of 40 Gy.

INTRODUCTION: Combination chemotherapy of gemcitabine and cisplatin (GC) is the standard treatment for patients with urothelial cancer (UC). However, hematological toxicity is a major side effect of GC therapy in patients with UC. In particular, discontinuation of the GC therapy is associated to adverse events such as hematological toxicity. Some studies have reported general risk factors of hematological toxicity such as age. However, little is known about risk factors for GC therapy-associated hematological toxicity in patients with UC. OBJECTIVE: We aimed to identify risk factors for hematological toxicity in patients with UC receiving GC therapy. METHODS: We performed a retrospective evaluation of the data of 128 patients with UC who received GC therapy. The study end point was defined as the occurrence of grade 4 neutropenia and grade ≥3 thrombocytopenia. Logistic regression analysis was used to determine risk factors that were significantly associated with neutropenia and thrombocytopenia. RESULTS: In total, 62 (48.4%) patients experienced grade 4 neutropenia, and 27 (21.1%) patients experienced grade ≥3 thrombocytopenia. In the multivariate analysis, performance status (PS) ≥1 (odds ratio [OR] 3.764, 95% confidence interval [CI] 1.410-10.047, p = 0.008) and neutrophil count (OR 0.648, 95% CI 0.468-0.898, p = 0.009) were significantly associated with grade 4 neutropenia. Platelet count (PLT) (OR 0.896, 95% CI 0.832-0.966, p = 0.004) and potassium (K) level (OR 6.966, 95% CI 1.313-36.989, p = 0.023) were also significantly associated with grade ≥3 thrombocytopenia. CONCLUSIONS: PS ≥ 1, neutrophil count, PLT, and K level were important risk factors for GC therapy-induced hematological toxicity in patients with UC. To continue GC therapy, further management systems by hematological toxicity risk factors for patients with UC will be required.

The aim of this study was to assess the acute effects of clonazepam and clonidine on rhythmic masticatory muscle activity in young adults with primary sleep bruxism, as well as accompanying effects on sleep architecture and cardiac activity. This study used a double-blind, crossover, placebo-controlled design. Polysomnography was performed on 19 subjects [nine men and 10 women; mean age (±SE): 25.4 ± 2.7 years] for 5 nights. The first 2 nights were used for the habituation and diagnosis of sleep bruxism. The other 3 nights were randomly assigned for clonazepam (1.0 mg), clonidine (0.15 mg) or placebo (all administered 30 min before bedtime). Sleep, oromotor activity and cardiac activity variables were assessed and compared among the three drug conditions. Clonidine significantly reduced the median percentage of time spent in the rapid eye movement sleep stage compared with placebo and clonazepam. The number of rhythmic masticatory muscle activity episodes was reduced with clonidine by >30% compared with placebo and clonazepam. The reduction of rhythmic masticatory muscle activity index by clonidine was associated with an increase of mean RR intervals (slower heart rate) during quiet sleep periods and during a 70-s period before the onset of rhythmic masticatory muscle activity episodes. However, no changes in cardiac activity variables were observed for clonazepam. In young adults with primary sleep bruxism, clonidine was significantly more effective in suppressing sleep bruxism than clonazepam. The acute effects of clonidine on rhythmic masticatory muscle activity episodes may be mediated by suppression of autonomic nervous system activity and non-rapid eye movement-rapid eye movement sleep processes.

We retrospectively evaluated clinical data from patients with advanced non-small-cell lung cancer (NSCLC) treated with third-generation chemotherapy agents prior to treatment, to determine a reliable method for predicting prognosis in such patients. We analyzed 100 patients who received third-generation agents (paclitaxel, docetaxel, gemcitabine, irinotecan, and vinorelbine) for the treatment of advanced NSCLC. Factors significantly related to prognosis were evaluated using the Cox regression model, and the prognostic index (PI) was determined by combining these factors. The mean follow-up duration was 12.6 months (0.2-67.0 months). Multivariate analysis identified pleural effusion, absolute neutrophil count (ANC), and C-reactive protein (CRP) level as significant factors that independently contribute to prognosis in patients with advanced NSCLC treated with third-generation agents (p < 0.05). The PI was calculated using these 3 factors, according to the following formula: PI = 0.581 × pleural effusion + 0.125 × ANC + 0.105 × CRP. The death rate in the group with the highest PI scores was significantly higher than in the group with the lowest scores (p < 0.001). Pleural effusion, ANC, and CRP level were the most important factors that contributed to prognosis following chemotherapy with third-generation agents in patients with advanced NSCLC. The PI is suggested to be an appropriate index to predict the prognosis of patients with NSCLC.

BACKGROUND/AIMS: We performed this retrospective cohort study to identify prognostic factors for unresectable pancreatic cancer treated with current standard therapy using gemcitabine (GEM) or S-1 and to stratify patients prior to treatment using a prognostic index (PI). METHODOLOGY: We analyzed 182 patients with unresectable pancreatic cancer, who had received GEM or S-1 as first-line chemotherapy. Factors that contributed to the prognosis were identified by univariate and multivariate analysis using a Cox proportional hazards model. The PI was constructed using the factors identified in the multivariate analysis. RESULTS: By multivariate analysis, performance status (PS), stage, and absolute neutrophil count (ANC) were identified as factors that independently contributed to the prognosis of unresectable pancreatic cancer (P < 0.05). The hazard ratios were 1.69, 3.33, and 1.18, respectively. In addition, PI was calculated using these three factors. Patients were classified into three groups according to the PI values. A significant difference was observed among the survival curves of these three groups (P < 0.05). CONCLUSIONS: We identified three prognostic factors in the population after the introduction of S-1, and have created a simple and useful PI. This index demonstrates the ability to accurately classify advanced pancreatic cancer patients before the start of treatment.

Introduction: We investigated the factors associated with readmission in patients with congestive heart failure (HF) receiving long-term administration of tolvaptan (TLV) to support treatment decisions for HF. Methods: This retrospective cohort study included 181 patients with congestive HF who received long-term administration of TLV. Long-term administration of TLV was defined as the administration of TLV for 60 days or longer. The outcome was a readmission event for worsening HF within 1 year after discharge. Significant factors associated with readmission were selected using multivariate analysis. To compare the time to readmission using significant factors extracted in a multivariate analysis, readmission curves were constructed using the Kaplan-Meier method and analysed using the log-rank test. Results: The median age was 78 years (range, 38-96 years), 117 patients (64.6%) were males, and 77 patients (42.5%) had a hospitalisation history of HF. Readmission for worsening HF within 1 year after long-term TLV treatment occurred in 62 patients (34.3%). In the multivariate analysis, estimated glomerular filtration rate (eGFR) <30 mL/min/1.73 m2 (odds ratio, 3.22; 95% confidence interval, 1.661-6.249; P = 0.001) was an independent significant factor. When eGFR at discharge was divided into two groups (eGFR < 30 vs. eGFR ≥ 30), readmission rates within 1 year were 53.3% vs. 25.4%, respectively (P = 0.001). Conclusion: We revealed that eGFR was strongly associated with readmission in patients with HF who received long-term administration of TLV. Furthermore, we showed that eGFR is an important indicator in guiding treatment of HF in patients receiving TLV.
RESUMO
Migraine is a multifactorial disease with various factors, such as genetic polymorphisms and personality traits, but the contribution of those factors is not clear. To clarify the pathogenesis of migraine, the contributions of genetic polymorphisms and personality traits were simultaneously investigated using multivariate analysis. Ninety-one migraine patients and 119 non-headache healthy volunteers were enrolled. The 12 gene polymorphisms analysis and NEO-FFI personality test were performed. At first, the univariate analysis was performed to extract the contributing factors to pathogenesis of migraine. We then extracted the factors that independently contributed to the pathogenesis of migraine using multivariate stepwise logistic regression analysis. Using the multivariate analysis, three gene polymorphisms including monoamine oxidase A (MAOA) T941G, methylenetetrahydrofolate reductase (MTHFR) C677T, and tumor necrosis factor beta (TNF-ß) G252Α, and the neuroticism and conscientiousness scores in NEO-FFI were selected as significant factors that independently contributed to the pathogenesis of migraine. Their odds ratios were 1.099 (per point of neuroticism score), 1.080 (per point of conscientiousness score), 2.272 (T and T/T or T/G vs G and G/G genotype of MAOA), 1.939 (C/T or T/T vs C/C genotype of MTHFR), and 2.748 (G/A or A/A vs G/G genotype of TNF-ß), respectively. We suggested that multiple factors, such as gene polymorphisms and personality traits, contribute to the pathogenesis of migraine. The contribution of polymorphisms, such as MAOA T941G, MTHFR C677T, and TNF-ß G252A, were more important than personality traits in the pathogenesis of migraine, a multifactorial disorder.

BACKGROUND/AIMS: Severity-based treatment is not homogenously effective for acute cholangitis patients and some are resistant to early treatment. We performed a retrospective cohort study involving acute cholangitis patients and analyzed factors strongly associated with resistance to early treatment. METHODOLOGY: The subjects were 94 patients admitted to the Department of Gastroenterology, Showa University Hospital and diagnosed with acute cholangitis. The endpoint was set as the presence or absence of resistance to early treatment. Background and blood test results of the patients immediately after admission were surveyed and significant factors independently contributing to resistance to early treatment were extracted from the surveyed factors employing a logistic regression model. RESULTS: The mean age of the patients was 73.2 ± 11.6 years and 58 were male (61.7%). Jaundice, fever and abdominal pain were observed in 46 (48.9%), 66 (70.2%) and 85 patients (90.4%), respectively. Twenty-eight patients (29.8%) were resistant to early treatment. On multivariate analysis, 3 factors (fever, serum amylase level and systolic blood pressure (below 100 mm Hg)) were extracted as significant factors independently contributing to resistance to early treatment (p<0.05). CONCLUSIONS: If such resistance can be predicted before treatment, appropriate treatment may be selected to shorten the persistence of symptoms, improving the patient's QOL.

BACKGROUND/AIM: Factors predicting the appearance of neutropenia were evaluated in patients with advanced pancreatic cancer undergoing gemcitabine hydrochloride (GEM) therapy. METHODOLOGY: The subjects were 92 patients who were diagnosed with unresectable advanced pancreatic cancer and underwent GEM therapy. Mono- and multivariate analyses were performed concerning each evaluated factor. The toxicity index (TI) was also prepared by combining the extracted predictive factors. RESULTS: Severe neutropenia occurred in 26 patients (28.2%). As a result of multivariate analysis, the white blood cell count (WBC), CA19-9 and liver metastasis were extracted as factors independently and significantly contributing to the appearance of severe neutropenia (p<0.05). The TI was prepared by combining these 3 factors and their regression coefficients: TI = 4.777-0.605xWBC (x103/microL)-0.511xlog (CA19-9)-1.285xliver metastasis. CONCLUSIONS: The WBC, CA19-9 and liver metastasis before treatment were shown to be related to the appearance of severe neutropenia after GEM therapy.

Appropriate use of opioid analgesics according to the World Health Organization pain relief ladder has provided pain relief to many patients with cancer pain. However, a proportion of patients fail to achieve sufficient pain relief and develop opioid resistance. Individual risk factors may relate to opioid resistance. Therefore, we conducted a historical cohort study to identify risk factors for opioid resistance and to construct an index to predict it. We investigated salient factors at the time of opioid initiation in the medical records of 233 patients. The outcome was the achievement of stable pain at 14 days after opioid introduction. We identified factors contributing to opioid resistance by multivariate analysis (p < 0.05). We created a resistance score from the regression equation of the identified factors to predict opioid resistance. Forty-nine (21.0%) patients were opioid resistant without achieving the outcome. Age, neuropathic pain, and alkaline phosphatase were extracted as significant factors for opioid resistance (p < 0.05). A resistance score was created from these factors and classified into binary values, the sensitivity was 80.6% and the negative predictive value was 91.6%. The findings suggest that the resistance score could be a sensitive predictor of opioid resistance before opioid initiation.

AIM: Atomoxetine (ATX) is a non-central stimulant and a standard treatment for adult attention-deficit/hyperactivity disorder (ADHD). The long-term efficacy of Atomoxetine is about 40% at 6 months. The variability in efficacy between individuals is thought to be related to patient-specific factors, but no detailed research has been conducted. In this retrospective cohort study, we aimed to identify the factors associated with Atomoxetine efficacy. METHODS: A total of 147 patients with attention-deficit/hyperactivity disorder aged ≥18 years who were using Atomoxetine for the first time were included in this study. The outcome was treatment success (treatment maintained for at least 6 months and improvement in symptoms). Symptom assessment was based on the overall improvement in symptoms judged by an expert physician. RESULTS: Of the patient sample, 103 (70.1%) achieved the outcome. Logistic regression analysis identified "the maximum dose of ATX" and "gambling habit" as factors associated with efficacy ( P < 0.05). In the process of Atomoxetine titration, the larger the maximum dose, the higher the efficacy was shown to be. Gambling habits may be indicative of impulsivity, which is among the core symptoms of attention-deficit/hyperactivity disorder. Thus, a gambling habit may be considered a surrogate marker for impulsivity. CONCLUSIONS: Knowledge of these factors will help healthcare professionals to predict the likely efficacy of Atomoxetine in a given patient before subscribing it, facilitating individualized pharmacotherapy for adult attention-deficit/hyperactivity disorder.

BACKGROUND: We conducted a historical cohort study of patients with schizophrenia to identify more robust risk factors at discharge that contribute to readmission within a year. METHODS AND FINDINGS: The subjects underwent brief psychoeducation during hospitalization. Multivariate analysis was conducted using factors selected in the univariate analysis. Using logistic regression analysis, the number of hospital admissions (P = .01) and Schedule for Assessment of Insight Japanese version score (P = .04) were identified as risk factors for readmission, with odds ratios of 0.70 and 1.18, respectively. CONCLUSIONS: These results suggest that improvement in insight and early intervention may lead to a more stable community life.

Achondroplasia is the most common genetic form of human dwarfism, for which there is presently no effective therapy. C-type natriuretic peptide (CNP) is a newly identified molecule that regulates endochondral bone growth through GC-B, a subtype of particulate guanylyl cyclase. Here we show that targeted overexpression of CNP in chondrocytes counteracts dwarfism in a mouse model of achondroplasia with activated fibroblast growth factor receptor 3 (FGFR-3) in the cartilage. CNP prevented the shortening of achondroplastic bones by correcting the decreased extracellular matrix synthesis in the growth plate through inhibition of the MAPK pathway of FGF signaling. CNP had no effect on the STAT-1 pathway of FGF signaling that mediates the decreased proliferation and the delayed differentiation of achondroplastic chondrocytes. These results demonstrate that activation of the CNP-GC-B system in endochondral bone formation constitutes a new therapeutic strategy for human achondroplasia.

Objective We aimed to develop a scoring model to predict a low disease activity (LDA) in elderly rheumatoid arthritis (RA) patients initially treated with biological disease-modifying antirheumatic drugs (bDMARDs). Methods This retrospective cohort study included 82 elderly RA patients who initially received bDMARDs. The outcome was an LDA after bDMARDs initiation. We developed a predictive formula for an LDA using a multivariate analysis, the accuracy of which was assessed by the area under the curve (AUC) of the receiver operating characteristic curves; the scoring model was developed using the formula. For each factor, approximate odds ratios were scored as an integer, divided into three groups based on the distribution of these scores. In addition, the scoring model accuracy was assessed. Results The mean age was 73.5±6.0 years old, and 86.6% were women. An LDA was achieved in 43 patients (52.4%). The predictive formula for an LDA was prepared using six factors selected for the multivariable analysis: the neutrophil-to-lymphocyte ratio (NLR), anemia, the 28-joint disease activity score with erythrocyte sedimentation rate (DAS28-ESR), serum level of matrix metalloproteinase-3 (MMP-3), diabetes mellitus (DM), and rheumatoid factor (RF). The AUC for the formula was 0.829 (95% confidence interval, 0.729-0.930). The odds ratios of the six factors were scored (DAS28-ESR and serum MMP-3=1 point, NLR, anemia, DM, and RF=2 points) and divided into three groups (≤4, 5-7, and ≥8). The high-score group (≥8) achieved a positive predictive value of 83%. Conclusion The scoring model accurately predicted an LDA in elderly RA patients initially treated with bDMARDs.

INTRODUCTION: We investigated factors predicting the addition of disease-modifying antirheumatic drugs (DMARDs) after an initial methotrexate (MTX) monotherapy in rheumatoid arthritis (RA) patients to support an early decision on the DMARDs addition. METHODS: This retrospective cohort study included 311 patients who were diagnosed with RA and started on MTX monotherapy at Showa University Hospital, Japan. The outcome was addition of DMARDs after an initial MTX monotherapy at 6 months. Baseline patient characteristics were compared between the DMARDs addition and MTX monotherapy continuation groups, and significant independent predictive factors for the addition of DMARDs were selected using multivariate analysis. RESULTS: The median age of patients was 62 years (range 24-90), 170 patients (73%) were women, the median swollen 28-joint count (SJC28) was 3 (0-28), and the median tender 28-joint count (TJC28) was 5 (0-28). DMARDs were added in 65 (27.9%) patients. In the univariate analysis, higher TJC28 and SJC28, concomitant use of nonsteroidal anti-inflammatory drugs, and intra-articular glucocorticoid (GC) injection history were significantly associated with the DMARDs addition. In the multivariate analysis, by adding covariates to the variables identified in the univariate analysis, SJC28 (odds ratio [OR] 1.390 per 5 joints increase; 95% confidence interval [CI], 1.036-1.866) and intra-articular GC injection history (OR 3.678; 95% CI, 1.170-11.557) were independent predictors of DMARDs addition. CONCLUSION: A higher SJC28 and intra-articular GC injection history may be useful predictors of DMARDs addition after the initial MTX monotherapy. We expect that using these predictors will enable an earlier shift to a more aggressive treatment. Key Points ã»We performed a retrospective cohort study with the addition of DMARDs as the outcome in patients with RA who were started on MTX monotherapy. ã»A higher SJC28 (OR 1.390; 95% CI, 1.036-1.866) and an intra-articular GC injection history (OR 3.678; 95% CI, 1.170-11.557) may be useful predictors for the addition of DMARDs of initiating MTX monotherapy at 6 months. ã»The use of such indicators may support an early decision on the addition of DMARDs after the initial MTX monotherapy.

Approximately 30% of patients experience nausea after initiation of opioid therapy, which can lead to poor quality of life. We aimed to identify risk factors for opioid-induced nausea at the initiation of opioid therapy by conducting a retrospective review of medical records of patients diagnosed by palliative care specialists with solid cancer and pain at the lesion site at Showa University Hospital between June 2005 and June 2011. The primary endpoint was the development of nausea grade ≥1 according to the Common Terminology Criteria for Adverse Events version 4.0 within 48 hours of initiation of opioid therapy. The median age of the 134 enrolled patients was 67.7 (range 28-95) years. Fifty-three percent were male and 44% had gastrointestinal cancer. Furthermore, 22.4% had opioid-induced nausea. Age (odds ratio (OR) 1.74; 95% confidence interval (CI), 1.13-2.69), edema (OR 5.83; 95% CI, 1.22-28.19), and gastrointestinal cancer (OR 2.61, 95% CI 1.07-6.36) were significantly associated with opioid-induced nausea. Prophylactic antiemetics were found to be ineffective.

The purpose of this study was to investigate the effects of heat-killed Lactobacillus plantarum strain b240 (b240) on systemic infection by Salmonella enterica serovar Typhimurium (S. Typhimurium) and to determine the mechanism by which b240 protects against infection. Mice were administered either b240 or saline orally for 3 weeks, and then inoculated with S. Typhimurium. The mice treated with b240 were significantly protected against S. Typhimurium as compared to those fed saline. Moreover, translocation of S. Typhimurium into each organ tested in the mice that received b240 tended to be less than in the control mice. An important mechanism of protection against infection was demonstrated by the ability of b240 to inhibit both binding by and invasion of S. Typhimurium into cells. These results indicate that nonviable lactic acid bacteria also play important roles in preventing infection by enteric pathogens.

OBJECTIVE: To assess the cost-effectiveness of chemotherapy for patients with non-resectable pancreatic cancer, we compared two regimens containing either gemcitabine (GEM) or S-1. METHODS: We developed a decision tree that showed the clinical processes of non-resectable pancreatic cancer patients. We calculated the probabilities of endpoint and life months gained (LMG) based on previously reported articles. To estimate the costs, we analyzed medical records of 44 inpatients with non-resectable pancreatic cancer treated with GEM(n=34)or S-1(n=10). Sensitivity analysis was used to check the robustness of the results. RESULTS: In the GEM group and S-1 group, costs were 1,636,393 and 985,042 yen, and LMG was 6. 0 and 9. 0 months, respectively. Thus, the cost-effectiveness ratio(CER)was calculated to be 272,732 and 109,449 yen/LMG, respectively, and the incremental cost effectiveness ratio (ICER) was -217,117 yen/LMG. The sensitivity analysis showed that the result was definitely robust. CONCLUSION: Our findings suggest that the markedly cost-effective S-1 regimen could prolong LMG with less cost than the GEM regimen.

BACKGROUND: Pre-anaesthesia hypertension (PAH) occurs when the blood pressure (BP) in patients before surgery, in the operating room, before anaesthesia induction, temporally elevates regardless of normal ambulatory recorded BP or self-measured BP at home. PAH might be caused by anxiety and mental stress about the anaesthesia and surgery. We know that most of the patients with sustained hypertension (SH) are elders, males, obese subjects, and dyslipidaemic subjects. Furthermore, most of the patients with white coat hypertension, which is caused by mental stress about the medical environment of an outpatient, clinic, and hospital ward, are elders, females, and non-smokers. In the present study, we investigated some relevant clinical characteristics influencing PAH. METHODS: Sampling data on patients more than 20 years old, who underwent consecutive operations under general, intrathecal, or epidural anaesthesia were retrospectively collected from hospital records and anaesthesia records. Hospital-room hypertension (HH) was defined as systolic BP (sBP) greater than or equal to 140 mm Hg in the hospital room before anaesthesia and surgery. Operating-room hypertension (OH) was defined as sBP greater than or equal to 140 mm Hg in the operating room before anaesthesia induction. RESULTS: 112 and 119 patients belonged to the OH and operating-room normotension (ON) groups, respectively. The OH group members were significantly older than the ON group members. Body mass index in the OH group was significantly greater than in the ON group. The proportions of males, dyslipidaemic subjects, and non-smokers in the OH group were significantly higher than in the ON group. In the logistic regression analysis, age, body mass, dyslipidaemia, and HH were selected as significant factors that contribute independently to OH (odds ratios; 1.045, 1.031, 2.912, and 4.354, respectively). CONCLUSIONS: The clinical characteristics of the patients with OH are: elders, obese subjects, dyslipidaemic subjects, and hospital-room hypertensive subjects. Ageing, obesity, dyslipidaemia, and HH are clinical risk factors relating to PAH.

PURPOSE: To identify factors for choking in psychiatric wards that can be easily screened. DESIGN AND METHODS: Data were collected from patients admitted to the acute phase psychiatric wards who were assessed for swallowing function by dentists. We defined 47 and 102 patients of choking in the high- and low-risk groups, respectively. FINDINGS: Through multivariate analysis, we identified basal metabolic index and two Drug-induced Extra-pyramidal Symptoms Scale items, bradykinesia and tremor, as independent choking factors. PRACTICE IMPLICATIONS: Choking risk is related to patient tolerability rather than to the absolute severity of psychiatric symptoms or psychotropic dose.
