The present study examined the effect of the long-term intake of chicken breast extract (CBEX), which contains carnosine and anserine, on carnosine content in skeletal muscles of humans and on short-period exercise performance with high intensity.
Before and after CBEX was orally given to 13 healthy male subjects for 30 days, pieces of their muscle (M. vastus lateralis) were excised and carnosine concentration in the muscle was measured. Before and after the test period, the subjects exercise performance (mean and peak power body weight) was determined by pedaling for 30 sec. On the basis of baseline concentrations of carnosine, the subjects were classified into two groups: low (n=8) and high (n=5) carnosine-baseline groups. In the former group, intake of CBEX increased carnosine concentration in the muscle (p<0.05), resulting in significant correlation between increased rate of carnosine concentration and mean power. These results suggest that exercise performance depends on carnosine concentration in the muscle, and that taking carnosine-containing foods may improve exercise performance.

Metabolic syndrome develops because of an accumulation of intra-abdominal fat. In Kampo medicine, an abdominal examination is commonly performed for the diagnosis of diseases. Thus, we examined the relationship between metabolic syndrome and abdominal tension. Our subjects were 999 people (619 males and 380 females) who underwent regular physical check-ups. Metabolic syndrome was diagnosed in 14.5% (21.3% of males and 3.4% of females) and the prevalence rate of subjects with metabolic and pre-metabolic syndromes was 40.8% (55.9% of males and 16.3% of females). In addition, abdominal examinations detected 19.1% of hyperfunction, 64.6% of intermediate function, and 16.3% of hypofunction. Almost subjects with abdominal hyperfunction were classified as metabolic or pre-metabolic syndrome, and neither metabolic nor pre-metabolic syndrome was present in subjects with abdominal hypofunction. In conclusion, assessment of abdominal tension may become an additional valuable screening method for metabolic syndrome.

　　This study is designed to clarify the effects of increases in a rehabilitation session on the functional outcome of hip fractures in the subacute phase.　　Of 95 patients with hip fractures admitted to our subacute care ward between November 2010 and March 2012, five patients transferred to another ward due to complications were excluded, and 90 patients were taken up. The 90 patients were divided into two groups: 22 patients who underwent rehabilitation before an increase in the frequency of rehabilitation sessions (early-phase group) and 68 who underwent rehabilitation after an increase in the frequency (later-phase group). Outcomes, such as the number of rehabilitation sessions, length of hospital stay, FIM at the time of discharge, FIM efficiency and destination after hospital discharge, were compared between the two groups.　　In a comparison of all patients, the number of rehabilitation sessions significantly increased (p<0.001), but there was no significant difference in FIM at the time of discharge from hospital, FIM efficiency and post-discharge destination. Group “Rank A” stood out in a comparison of the degree of independence enjoyed by the disabled elderly in their daily life before they suffered injuries (p<0.05). Group “Rank I” stood out in a comparison of the degree of independence in the daily life by the elderly with dementia, while they were in hospital (p⁢0.05). The FIM efficiency of the later-phase group was significantly higher than that of the early-phase group.　　It is presumably effective to begin intensive rehabilitation for patients whose ADL ability is somewhat reduced and those who have cognitive impairments. It has been thought that cognitive impairment was one of the factors that inhibit rehabilitation for hip fractures. However, it has been suggested that improvements in ADL are possible with increases in rehabilitation sessions for cases with mild cognitive impairment.

Objective: To develop and confirm the validity of a Biological Prognostic Score using only blood test results for prediction of prognosis in patients with advanced cancer. Methods: We conducted parametric survival time analysis using blood test results, age, sex, and primary diagnosis as independent variables, and event of death as a dependent variable, among patients in a palliative care unit (a development cohort). We then developed the Biological Prognostic Score (BPS). Thereafter, we confirmed the accuracy of the BPS and the Palliative Prognostic Index (PPI) prospectively among patients, who withdrew or withheld further curative or life-prolonging therapies, in other facilities (a validation cohort). Results: We developed the BPS, which consists of cholinesterase, blood urea nitrogen, and total iron-binding capacity, from 122 patients in a development cohort. We then examined 195 patients in a validation cohort and found that the area under the receiver operating characteristic curve for 1-9 week survival prediction was BPS=0.76-0.86 and PPI=0.69-0.73. Discussion: Our results suggest that the BPS was valid. It will be necessary to perform further examinations in multiple facilities and to explore more generalized parameters that could replace total iron-binding capacity in our BPS.

BACKGROUND: To identify a new strategy for postoperative pain management, we investigated the analgesic effects of allopregnanolone (Allo) in an incisional pain model, and also assessed its effects on the activities of the primary afferent fibers at the dorsal horn. METHODS: In experiment 1, 45 rats were assigned to Control, Allo small-dose (0.16 mg/kg), and Allo large-dose (1.6 mg/kg) groups (n = 15 in each). The weight bearing and mechanical withdrawal thresholds of the hind limb were measured before and at 2, 24, 48, and 168 h after Brennan's surgery. In experiment 2, 16 rats were assigned to Control and Allo (0.16 mg/kg) groups (n = 8 in each). The degree of spontaneous pain was measured using the grimace scale after the surgery. Activities of the primary afferent fibers in the spinal cord (L6) were evaluated using immunohistochemical staining. RESULTS: In experiment 1, the withdrawal threshold of the Allo small-dose group was significantly higher than that of the Control group at 2 h after surgery. Intergroup differences in weight bearing were not significant. In experiment 2, intergroup differences in the grimace scale scores were not significant. Substance P release in the Allo (0.16 mg/kg) group was significantly lower than that in the Control group. CONCLUSIONS: Systemic administration of Allo inhibited mechanical allodynia and activities of the primary afferent fibers at the dorsal horn in a rat postoperative pain model. Allo was proposed as a candidate for postoperative pain management.

STUDY DESIGN: Retrospective study. PURPOSE: We conducted a study to investigate the time course changes in bone metabolic markers after the administration of the anti-receptor activator of nuclear factor-kappa B ligand (RANKL) antibody and to assess drug compliance among osteoporotic patients. OVERVIEW OF LITERATURE: The anti-RANKL antibody is expected to provide an improvement in those with a bone metabolism disorder. However there are only a few clinical reports available on the effect of treatment. METHODS: We included 40 post-menopausal osteoporotic patients who received the anti-RANKL antibody. To determine the time course changes in the bone metabolic markers, we measured the serum tartrate-resistant acid phosphatase 5b (TRACP 5b; a bone resorption marker) and the serum N-terminal propeptide of type 1 collagen (P1NP; a bone formation marker) levels prior to and 1 month after administrating the anti-RANKL antibody. To evaluable drug compliance, we assessed the dropout rate during treatment and at 6 months after treatment. RESULTS: The average TRACP 5b level significantly decreased from 574.8 mU/dL before treatment to 153.2 mU/dL 1 month after treatment (p<0.05). There was no significant difference in the average P1NP level, which was 56.9 microG/L and 35.1 microG/L before and 1 month after treatment, respectively (p>0.05). As for drug compliance, we did not have any dropouts during the treatment or after 6 months (dropout rate: 0%). CONCLUSIONS: Our study suggests that anti-RANKL antibody treatment suppresses bone resorption and maintains bone formation.

Background/Aims: Belching is the act of expelling gas from the stomach or esophagus noisily through the oral cavity. Although it is a physiological phenomenon, belching may also be a symptom of upper gastrointestinal diseases such as reflux esophagitis and functional dyspepsia (FD). A detailed epidemiology of belching has not yet been reported. The aim of this study is to examine the prevalence and clinical characteristics of clinically significant belching (CSB) in adults. Methods: We analyzed 1998 subjects who visited the hospital for annual health checkups. Belching was evaluated by a simple question “Do you burp a lot?” and scored as 0 (never), 1 (occasionally), 2 (sometimes), 3 (often), or 4 (always). Subjects with CSB were defined ashaving scores ≥ 3. We also collected the clinical parameters, endoscopic findings, and data according to the Athens Insomnia Scale, Rome IV questionnaire, and Hospital Anxiety and Depression Scale (HADS). Results: Of the 1998 subjects, 121 (6.1%) had CSB. Subjects with CSB had FD more commonly than reflux esophagitis, but presence of heartburn was high (10.7% vs 3.1%). In addition, the HADS and Athens Insomnia Scale scores in subjects with CSB were significantly higher than those in subjects without CSB. Presence of heartburn (OR, 2.07; 95% CI, 1.05-4.09), presence of FD (OR, 2.12; 95% CI, 1.33-3.36), anxiety/depression (OR, 2.29; 95% CI 1.51-3.45), and sleep disturbances (OR, 1.73; 95% CI, 1.14-2.61) were significantly associated with CSB. Conclusion The detailed epidemiology of belching in the general adult population was clarified.

Methods: Study participants comprised five healthy volunteers (mean age, 27.2 years) and 27 patients with LSS (mean age, 58.4 years) who were individually assessed using 3.0 Tesla magnetic resonance imaging. Intraspinal ADC and FA values of 10 intervertebral discs from healthy volunteers and 52 intervertebral discs from LSS patients were measured. Also, intraspinal canal area, Schizas classification (A: normal, B: mild stenosis, C: severe stenosis) and correlations with symptoms were investigated. Clinical symptoms were checked for the presence of low back pain (LBP), intermittent claudication (IMC), and bladder and bowel dysfunction (BBD). Results: Compared to healthy individuals, LSS patients had significantly lower ADC (p<0.05) and significantly higher FA values (p<0.01). In Schizas classification, stenosis worsened from A to C. ADC values decreased significantly while FA values increased significantly in that order (p<0.05). A positive correlation was found between intraspinal canal area and ADC values (r=0.63, p<0.01) and a negative correlation between intraspinal canal area and FA values (p=−0.61, p<0.01). No correlations were noted between LBP and ADC or FA values. On the other hand, ADC values were significantly lower (p<0.05) and FA values were significantly higher (p<0.05) in patients with IMC or BBD. Conclusions Intraspinal DTI parameters such as ADC and FA values were associated with the Schizas classification, intraspinal canal area, and clinical symptoms, suggesting that ADC and FA may be useful for quantitative assessment of LSS.
