CHOP-like regimen combined with rituximab is a standard chemotherapy for diffuse large B-cell lymphoma (DLBCL). The relative dose intensity (RDI) was proposed as an index of the dose and administration interval of agents. Previous studies reported that the maintenance of the RDI during CHOP therapy improved the treatment results. However, few studies regarding RDI have reviewed patients receiving combination therapy with CHOP and rituximab. We investigated the influence of RDI maintenance, involving combination therapy with rituximab, on therapeutic effects in patients with DLBCL. We retrospectively examined 152 DLBCL patients who were treated with CHOP-like regimen combined with rituximab in whom the RDI could be followed up. Multivariate analysis revealed that international prognosis index (IPI) high intermediate-high (HI-H) (p=0.005) and RDI of less than 70% (p=0.007) were independent prognostic factors for low progression free survival. Concerning overall survival, IPI HI-H (p=0.027) and an RDI of less than 70% (p=0.002) were involved in an unfavorable prognosis. In addition, age over 60 years (p=0.003), R-THPCOP (p=0.034), or the presence of febrile neutropenia (p=0.004) made RDI maintenance difficult, and prophylactic G-CSF therapy (p=0.026) was useful for maintaining the RDI. Maintaining the RDI is important even in the era of rituximab-combined chemotherapy for DLBCL. © 2010 Springer-Verlag.

Background: The repression of negative emotions is a personality factor that received considerable attention in the 1950-60s as being relevant to the onset and course of rheumatoid arthritis (RA). Despite subsequent, repeated criticisms of the cross-sectional nature of the earlier studies, even to date few prospective studies have been reported on this issue. This multicenter study prospectively examined if " rational and antiemotional" behavior (antiemotionality), characterized by an extreme tendency to suppress emotional behaviors and to rationalize negative experiences in conflicting interpersonal situations, is associated with the functional prognosis of patients with RA.Methods: 532 patients with RA who regularly visited one of eight hospitals/clinics in Japan in 2000 were recruited for study. All completed a self-administered baseline questionnaire about lifestyle and psychosocial factors including antiemotionality. Two years after, 460 (mean age, 56.1 years; 54 men and 406 women) of 471 patients who continued to visit the clinics agreed to take the follow-up questionnaire. The functional status of the patients was evaluated by rheumatologists based on the ACR classification system.Results: A multiple logistic regression model that included baseline demographic, disease activity/severity-related, therapeutic, and socioeconomic factors as covariates found a tendency toward higher antiemotionality to be related to poorer functional status at follow-up. This relationship was not explained by lifestyle factors.Conclusions: Antiemotionality may be a prognostic factor for the functional status of patients with RA. This finding sheds light on a seemingly forgotten issue in the care of patients with RA. © 2014 Nagano et al.; licensee BioMed Central Ltd.

OBJECTIVES:Chronic intestinal pseudo-obstruction (CIPO) is a rare, serious motility disorder, with life-threatening complications over time. However, lack of an established, non-invasive diagnostic method has caused delays i. The diagnosis of this intractable disease. Cine-magnetic resonance imaging (MRI) is an emerging technique, with a potential to evaluat. The motility o. The entire bowel. We compared small bowel motility in healthy volunteers, patients with irritable bowel syndrome (IBS), and those with CIPO, using cine-MRI, and evaluate. The usefulness of cine-MRI as a novel diagnostic method for CIPO.METHODS:Twelve healthy volunteers, IBS patients, and CIPO patients prospectively underwent cine-MRI at 1.5 T. Luminal diameter, contraction ratio, and contraction cycle were measured and compared betwee. The groups.RESULTS:Cine-MRI provided sufficient dynamic images to asses. The motility o. The entire small bowel. Luminal diameter (mean±s.d.) in CIPO patients was significantly higher than that in healthy volunteers and IBS patients (43.4±14.1, 11.1±1.5, and 10.9±1.9 mm, respectively), and contraction ratio was significantly lower in CIPO patients than that in healthy volunteers and IBS patients (17.1±11.0%, 73.0±9.3%, and 74.6±9.4%, respectively). No significant differences were observed i. The contraction cycle.CONCLUSIONS:This study i. The first to asses. The clinical utility of cine-MRI in CIPO patients. Cine-MRI clearly detected contractility impairments in CIPO patients. Cine-MRI is noninvasive, radiation-free, and can directly evaluat. The entire small bowel peristalsis, and can detec. The affected loops at a glance; therefore, it might be extremely useful fo. The diagnosis and follow-up of CIPO patients in clinical practice.

Haemodynamic changes in cerebral circulation are associated with the natural ageing process and associated pathology, leading to the development of incapacitating neurological and neurovascular diseases. Due to inherent biological limitations, current literatures mostly aimed at studying the correlation descriptively or quantifying the relationship in vitro or using computational models. In this paper, a model of a carotid-jugular fistula in the rat was used to create a haemodynamic insult to the intracranial arterial circulation and subsequent venous drainage. An arterial-venous (AV) fistula was created in 12 rats, 6 of which are normotensive Wistar-Kyoto strain (WKY) and the rest spontaneously hypertensive strain (SHR) with an additional 6 in each strains designed as controls without previous surgery. After 4 weeks of convalescence, all 24 rats were euthanised and their cerebral circulation was examined histomorphologically. We confirmed an intrinsic morphological difference between normotensive WKY and hypertensive SHR and found a modest but significant arterial shrinkage in both strains induced with AV fistula. We also reported that alterations in blood flow are also associated with marked extracellular matrix changes. We concluded that the model was suitable for studying the relative contributions of altering haemodynamic patterns and venous drainage on cerebrovascular changes. We also found that hypertension modulated cerebral vascular changes in addition to disrupted blood flow. © 2014 Ng et al.

Background: Stressors may differently affect human physiological systems according to the host properties relevant to psycho-behavioral processes that the stressors invoke. In a Japanese multicenter cohort study of patients with rheumatoid arthritis (RA), we examined if major life events differently contribute to the patients' functional prognosis according to their ability to identify emotions as manifest feelings when encountering the events (emotional responsiveness). Methods: 460 patients with RA completed a self-administered baseline questionnaire about psychosocial factors including emotional responsiveness. Two years later, they checked on a list of positive/negative personal events that happened during the two-year study period. Rheumatologists evaluated their functional status at baseline and follow-up using the ACR classification system. Results: In a multiple logistic regression model that included baseline demographic, disease activity/severity-related, therapeutic, and socioeconomic factors as covariates, none of the counts of positive, negative, or all life events was associated with the functional status at follow-up. In the subgroup with poor emotional responsiveness, however, these life event counts were all associated with a poorer functional prognosis (odds ratio of ACR class 3-4 vs. 1-2 associated with one increment in the all life-event count = 2.39, 95 % confidence interval = 1.27-4.48, p = .007), while no such relationship was evident for the rest of the patients. Conclusions: Major life events, whether positive or negative in nature, may have an impact on the disease course of patients with RA when the patient has poor emotional responsiveness to the event(s). © 2015 Nagano et al.
