Purpose and Methods: Infection and neoplastic fever is one of the common complication in patients with advanced cancer. To develop a novel method to differentiate neoplastic fever from infection, we performed a retrospective study of hospitalized terminally ill cancer patients at Seirei Hospice from April 2009 to August 2011. Results: We identified a consecutive sample of 12 patients with neoplastic fever and 12 patients with infection as a control. We extracted demographic data, laboratory data, vital signs and symptoms from medical charts. We found significant differences in difference in C-reacive protein value between afebrile and febrile period (p＜0.001), difference of white blood cell count between afebrile and febrile period (p=0.0017), percentages in neutrophil counts (p=0.023), percentages in lymphocyte counts at base line (p=0.011) and the presence of delirium (p=0.012). Conclusion: These findings suggest that we might differentiate neoplastic fever from infection with common laboratory data and their longitudinal change.

Ceftriaxone is one of the easily administrative antibiotics, but little is known about their role in palliative care settings. The aim of this study is to show the effect and the safety of ceftriaxone subcutaneous infusion to infection among advanced cancer patients. Consecutive patients who received ceftriaxone subcutaneous infusion at the Seirei Hospice from January 2013 to January 2014 were enrolled in this retrospective analyses. Primary outcome was the response rate of ceftriaxone, determined by improvement of symptoms within 3 days of ceftriaxone use. Secondary outcomes are inflammatory site reaction, and a comparison of the response rate between ceftriatone and other antibiotics. Among a total of 100 admitted patients, 10 patients used ceftriaxone subcutaneous infusion (4 for urinary tract infection, 4 for pneumonia, 2 for soft tissue infection). The response rate was 70% (95% confidence interval, 39－89). There was no inflammatory symptom at the insertion site observed. For comparisons, 16 patients used other antibiotics with the response rate of 74% (51－88).In conclusion, subcutaneous infusion of ceftriaxone can be useful in the treatment of infections of end－of－life cancer patients, and randomized controlled trial is promising.

PURPOSE: Recently, the clinical application of the forced oscillation technique (FOT) has progressed with the spread of commercially available FOT devices, including the impulse oscillation system and MostGraph. We investigated the usefulness of color 3D imaging of respiratory impedance in asthma using MostGraph. METHODS: Whole-breath and within-breath respiratory system resistance (Rrs) and reactance (Xrs) were measured in 78 patients with asthma. Color 3D images were classified into three patterns: the chronic obstructive pulmonary disease (COPD)-like pattern (high values of Rrs and Xrs with a marked respiratory cycle and frequency dependence), the asthma pattern (moderately high Rrs over the entire frequency and a respiratory cycle with slight Xrs changes), and a normal-like pattern (low Rrs and Xrs with few within-breath changes). The classification was performed by three researchers, who were unaware of the clinical information, and the clinical characteristics were compared among the three groups. RESULTS: Color 3D imaging provided a COPD-like pattern in 25 patients, an asthma pattern in 39 patients, and a normal-like pattern in 14 patients. Patients with the COPD-like pattern were predominantly female with a higher body mass index, lower forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC), and higher Rrs and Xrs values (whole-breath and within-breath variation). Those with the normal pattern had higher FEV1 and FVC, and a lower single-breath nitrogen washout slope. There were no differences in asthma control or exhaled nitric oxide levels among the three groups. CONCLUSIONS: These results suggest that color 3D imaging of respiratory impedance may show asthma phenotypes.

BACKGROUND AND OBJECTIVES: Reactive oxygen species (ROS) mediate various signaling pathways that underlie vascular inflammation in atherogenesis and cardiovascular diseases. Cardiac rehabilitation (CR) has a variety of multiple beneficial effects, including anti-inflammatory effects. The purpose of the present study was to investigate the effects of CR on ROS in patients with cardiovascular diseases. SUBJECTS AND METHODS: The serum level of derivatives of reactive oxidative metabolites, an index of oxidative stress, was measured in 100 patients with cardiovascular diseases before, and, subsequently, 3 and 6 months after, CR. A biological antioxidant potential (BAP) test was applied to assess the antioxidant power of the serum. RESULTS: The resting reactive oxidative metabolite levels decreased 3-6 months after CR {pre: 351+/-97 Carratelli unit (CARR U), 3 months: 329+/-77 CARR U, 6 months: 325+/-63 CARR U, all p<0.01} with the increase of the percentage of the predicted values of VO2 peak and the percentage of the predicted values of VO2 at the anaerobic threshold (VO2 AT) and the decrease of the B-type natriuretic peptide (BNP). The BAP test and antioxidative/oxidative stress ratio increased 6 months after CR. The % changes of the antioxidative/oxidative stress ratio was positively correlated with the % changes of VO2 AT, and negatively correlated with the % changes of the BNP. CONCLUSION: These results suggest that intensive supervised CR significantly improved exercise capacity, which may be attributable to an adaptive response involving more efficient oxidative metabolites or the increased capacity of endogenous anti-oxidative systems in patients with cardiovascular diseases.

Since the rectus femoris muscle is associated with trauma and disorders such as muscle strain, it is often a target for evaluation and treatment. However, in many studies, measurement results were obtained from only a part of the rectus femoris muscle and used as a representative value without considering the differences across the muscle. The rectus femoris muscle may change shape with knee flexion because the structure is complicated; it has an intramuscular tendon. The purpose of this study was to assess the changes in shape of the rectus femoris muscle during flexion of the knee joint in different directions. Twelve lower limbs of 12 male university students were analyzed. The rectus femoris muscle was divided into eight parts, and short-axis images were taken with an ultrasonic diagnostic imaging device at the knee joint; in extension; flexion at 30 °, 60 °, 90 °, and 120 °; muscle thickness; muscle width; and cross-sectional area. It was suggested that the thickness of the rectus femoris muscle increased from “A” to “F” due to knee flexion, and that this increase occurred because of stretching at the same site. In “G,” there was no difference between the angle conditions; conversely, in “H,” the muscle thickness decreased due to knee flexion. It should also be noted that D and E have the greatest muscle thickness when measuring in the knee flexion position.
