Objective: To examine the association between the mobilization level during intensive care unit (ICU) admission and independence in activity of daily living (ADL), defined as Barthel Index (BI)≥70. Methods: This was a post-hoc analysis of the EMPICS study involving nine hospitals. Consecutive patients who spend >48 hours in the ICU were eligible for inclusion. Mobilization was performed at each hospital according to the shared protocol and the highest ICU mobility score (IMS) during the ICU stay, baseline characteristics, and BI at hospital discharge. Multiple logistic regression analysis, adjusted for baseline characteristics, was used to deter-mine the association between the highest IMS (using the receiver operating characteristic [ROC]) and ADL. Results: Of the 203 patients, 143 were assigned to the ADL independence group and 60 to the ADL dependence group. The highest IMS score was significantly higher in the ADL independence group than in the dependence group and was a predictor of ADL independence at hospital discharge (odds ratio, 1.22; 95% confidence interval, 1.07–1.38; adjusted p=0.002). The ROC cutoff value for the highest IMS was 6 (specificity, 0.67; sensitivity, 0.70; area under the curve, 0.69). Conclusion These results indicate that, in patients who were in the ICU for more than 48 hours, that patients with good function in the ICU also exhibit good function upon discharge. However, prospective, multicenter trials are needed to confirm this conclusion.

We evaluated decreases in glycosylated hemoglobin (HbA1c) achieved by reducing carbohydrate from various sources in type 2 diabetes mellitus patients.

We evaluated decreases in glycosylated hemoglobin (HbA1c) achieved by reducing carbohydrate from various sources in type 2 diabetes mellitus patients.

Background: We evaluated decreases in glycosylated hemoglobin (HbA1c) achieved by reducing carbohydrate from various sources in type 2 diabetes mellitus patients. Methods: We followed up 138 male and 107 female outpatients on a moderate low-carbohydrate diet without diabetic medication for 6 months. Changes in carbohydrate sources (Δcarbohydrate) were assessed from 3-day dietary records at baseline and 6 months, and associations with changes in HbA1c (ΔHbA1c) were examined with Spearman’s correlation coefficients (rs) and multiple regression analysis. Results: ΔHbA1c was –1.5%±1.6% in men and –0.9%±1.3% in women, while Δtotal carbohydrate was –115.3±103.7 g/day in men and –63.6±71.1 g/day in women. Positive associations with ΔHbA1c were found for Δtotal carbohydrate (rs =0.584), Δcarbohydrate from soft drinks (0.368), confectionery (0.361), rice (0.325), bread (0.221), Chinese soup noodles (0.199) in men, and Δtotal carbohydrate (0.547) and Δcarbohydrate from rice (0.376) and confectionery (0.195) in women. Reducing carbohydrate sources by 50 g achieved decreases in HbA1c of 0.43% for total carbohydrate, 1.33% for soft drinks, 0.88% for confectionery, 0.63% for bread, 0.82% for Chinese soup noodles and 0.34% for rice in men and 0.45% for total carbohydrate, 0.67% for confectionery and 0.34% for rice in women, although mean reductions in carbohydrate from these sources were much smaller than that from rice. Conclusion Decreases in HbA1c achieved by reducing carbohydrate from soft drinks, confectionery, bread and Chinese soup noodles were 2- to 4-fold greater than that for rice. Our results will enable patients to decrease HbA1c efficiently (UMIN000009866).

Diagnosis of lumbar foraminal stenosis remains difficult. Here, we report on a case in which bilateral lumbar foraminal stenosis was difficult to diagnose, and in which diffusion tensor imaging (DTI) was useful. The patient was a 52-year-old woman with low back pain and pain in both legs that was dominant on the right. Right lumbosacral nerve compression due to a massive uterine myoma was apparent, but the leg pain continued after a myomectomy was performed. No abnormalities were observed during nerve conduction studies. Computed tomography and magnetic resonance imaging indicated bilateral L5 lumbar foraminal stenosis. DTI imaging was done. The extraforaminal values were decreased and tractography was interrupted in the foraminal region. Bilateral L5 vertebral foraminal stenosis was treated by transforaminal lumbar interbody fusion and the pain in both legs disappeared. The case indicates the value of DTI for diagnosing vertebral foraminal stenosis.

STUDY DESIGN: Retrospective observational study. PURPOSE: To examine fractional anisotropy (FA) values and apparent diffusion coefficient (ADC) values of damaged nerves to discriminate between lumbar intraspinal stenosis (IS) and foraminal stenosis (FS) using diffusion tensor imaging (DTI) OVERVIEW OF LITERATURE: It is important in the selection of surgical procedure to discriminate between lumbar IS and FS, but such discrimination is difficult. METHODS: There were 9 cases of IS, 7 cases of FS, and 5 healthy controls. The regions of interest were established in the lumbar intraspinal zone (Iz), nerve root (N), and extraforaminal zone (Ez). The FA and ADC values were measured on the affected and unaffected sides of the nerves. The FA ratio and the ADC ratio were calculated as the affected side/unaffected side ×100 (%). RESULTS: In the Ez, the FA value was significantly lower in FS than in IS (p<0.01). FA ratio was significantly lower in FS than in IS for the Ez (p<0.01). In the Iz, the ADC value was significantly higher in IS than FS (p<0.01). ADC ratio was significantly higher in FS than in IS for the N and Ez (p<0.05). For the Ez, receiver operating characteristic analysis of parameters revealed that the FA values showed a higher accuracy for the diagnosis of FS than the ADC values, and the FA value cut-off value was 0.42 (sensitivity: 85.7%, false positive: 11.1%) and the FA ratio cut-off value was 83.9% (sensitivity: 85.7%, false positive: 22.2%). CONCLUSIONS: The low FA value in the extraforaminal zone suggests the presence of foraminal stenosis. When the FA value and FA ratio cut-off value were established as 0.42 and 83.9%, respectively, the accuracy was high for the diagnosis of foraminal stenosis. It may be possible to use DTI parameters to help in the discrimination between IS and FS.

In this study, we examined the feasibility of using subzonal cell injection with electrofusion for interspecies somatic cell nuclear transfer (iSCNT) to produce sei whale embryos and to improve their developmental capacity by investigating the effect of osmolarity and macromolecules in the culture medium on the in vitro developmental capacity. Hybrid embryos produced by the electrofusion of fetal whale fibroblasts with enucleated porcine oocytes were cultured in modified porcine zygote medium-3 to examine the effects of osmolarity and fetal serum on their in vitro developmental capacity. More than 66% of the whale somatic cells successfully fused with the porcine oocytes following electrofusion. A portion (60~81%) of the iSCNT whale embryos developed to the two- to four-cell stages, but no embryos were able to reach the blastocyst stage. This developmental arrest was not overcome by increasing the osmolarity of the medium to 360 mOsm or by the addition of fetal bovine or fetal whale serum. Our results demonstrate that sei whale-porcine hybrid embryos may be produced by SCNT using subzonal injection and electrofusion. The pig oocytes partly supported the remodeling and reprogramming of the sei whale somatic cell nuclei, but they were unable to support the development of iSCNT whale embryos to the blastocyst stage.

A 73-year-old man was admitted to the hospital on March 31, 2000 because of nonsustained ventricular tachycardia (VT). In 1983, he was diagnosed as having apical hypertrophic cardiomyopathy (APH). Electrocardiograms showed high amplitude of R waves and giant negative T waves (GNT), and left ventriculography (LVG) revealed spade like configuration. He stopped medication without leave six months after the diagnosis. The latest ECG showed a decrease in amplitude of R waves, no signs of GNT, ST elevation in precordial leads, and an increase in QRS duration. LVG demonstrated midventricular obstruction, apical aneurysm, and the intraventricular pressure gradient in systolic phase was 56 mm Hg. No stenotic lesion was observed in coronary arteriography. Early diastolic paradoxic flow from the apical chamber toward the outflow of the left ventricle was detected by pulsed Doppler echocardiography. VT was successfully treated with beta-blocker and amiodarone, but he needed hospital treatment again one month later because of congestive heart failure. During the follow-up of APH, the decrease in amplitude of R waves and disappeasance of GNT, ST elevation, and the increase in QRS duration in electrocardiograms, and the detection of early diastolic paradoxic flow by echocardiography could be the predictors of developing apical aneurysm and/or left ventricular dysfunction.

We examined the clinical features, 12-leads ECG, Holter ECG, monitor ECG, and electrophysiologic study (EPS) in nine consecutive paroxysmal atrioventricular block (PAVB) patients treated in our hospital between 1995 and 2000. In some of them, parasympathetic nerve stimulating maneuvers, drug administration and head-up tilt test (HUT) were performed as provocative tests. EPS documented that the sites of AV block were within the His-Purkinje system (H-PSB) in five patients, proximal to the His bundle potential (AHB) in three patients. In the remaining one patient, the His bundle potential was not recorded. The main features of the patients with H-PSB were as follows: 1) often wide QRS complex with or without axis deviation; 2) variable degrees of AV conduction disturbance in a short period; 3) sinus tachycardia, and normal length and constant PQ intervals in a daytime being apt to precede PAVB; 4) rather long ventricular asystoles leading to abrupt syncope; 5) easy induction of the block by intravenousadministration of atropine. In the other hand, the features of the patients with AHB included: 1) narrow QRS; 2) progressively increasing or decreasing in PQ intervals preceding PAVB; 3) ventricular asystole lasting about 3 to 10 seconds; 4) the failure to induce PAVB by any probale provocative tests.
Although we treated all the patients with permanent pacemakers, there might have been other management method for AHB patients who had about 3-second ventricular asystole.
