The Kurashiki Prehospital Stroke Scale Is a Prehospital Scale That Can Predict Long-Term Outcome of Patients with Acute Cerebral Ischemia

Background and Purpose: Our aim was to confirm the clinical relationship between the Kurashiki Prehospital Stroke Scale (KPSS) scored by paramedics and favorable outcomes in patients with modified Rankin scale (mRS) scores of 0–1 assessed 3 months after symptom onset. Methods: We enrolled patients with acute stroke and transient ischemic attack showing symptoms on admission. Paramedics transferred patients to our hospital after estimating stroke severity using the KPSS. After categorizing patients into either the mRS 0–1 group (favorable outcome) or the mRS 2–6 group (no favorable outcome), we compared the background data between the two groups. We assessed KPSS scores predictive of a favorable outcome. Multivariate regression modeling was conducted to identify factors independently associated with a favorable outcome. Results: The study cohort comprised 147 patients with a premorbid status of mRS 0–1: 69 patients (47%) of them were in the mRS 0–1 group and 78 (53%) in the mRS 2–6 group at the follow-up 3 months after symptom onset. The median KPSS score was lower in the mRS 0–1 group than in the mRS 2–6 group (1 vs. 4, p Conclusion: KPSS score <3 apparently presents a reasonable cutoff for predicting a favorable outcome in patients with acute cerebral ischemia

New Paradigms of Radiotherapy for Bone Metastasis

Proper care of patients with bone metastasis requires interdisciplinary treatments. Radiotherapy (RT) plays a central role in the management of painful bone metastasis. External beam RT can provide rapid successful palliation of painful bone metastasis in 50–80% of patients, is associated with very few adverse effects and leads to complete pain relief at the treated site in up to one‐third of patients. Intensity‐modulated RT (IMRT) or stereotactic body RT (SBRT) enables the delivery of higher doses to the target tumor while minimizing the dose to adjacent organs. Reirradiation using IMRT or SBRT is a valuable option for the management of bone metastases. A multidisciplinary team, especially one consisting of a spinal surgeon and rehabilitation physician, is particularly useful for treating patients with spinal bone metastases characterized by spinal instability. Rehabilitation intervention which increases the physical activity level and prevents deconditioning is important. Future developments in surgical procedures and RT will likely improve the management protocols for bone metastases and technology to reduce metal artifacts in radiation planning might improve the efficacy and safety of combination therapy

Clinical study for evaluation of Percutaneous Transhepatic Gallbladder Drainage : PTCD associated with PTGBD

Eight cases of PTGBD were investigated. The average age was 69.3 years, and 6 cases were male and 2 cases were female. There were 6 cases of acute cholecystitis and 2 cases of malignant disease (1 middle bile duct cancer, 1 pancreas head cancer). Before state of PTGBD of these patients, severe cardiac disease and after posterior spinal fixation and other disease were observed. Using PTGBD, pain, fever, and other symptoms had remarkably improved in all patients. In all 6 patients with acute cholecystitis, CRP and leukocyte were significantly decreased as the 2 days after this procedure. PTCD associated with PTGBD was performd in 2 patients with middle or distal obstruction of the common bile duct. The bilirubin decrease rate"b" (b value) was-0.20±0.03 (M±SE) in the PTGBD+PTCD group and-0.096±0.15 (M±SE) in the only PTCD group, with a statistically significant difference (p<0.01). The procedure was effective in reducing jaundice

Beneficial effect of branched-chain amino acid supplementation on glycemic control in chronic hepatitis C patients with insulin resistance: Implications for type 2 diabetes

Branched-chain amino acids (BCAAs) improve disorders of albumin metabolism, quality of life, subjective symptoms, and prognosis in patients with chronic hepatitis. However, it remains unclear whether they improve insulin resistance. We examined the effects of BCAAs on glucose tolerance and insulin sensitivity in patients with chronic hepatitis C and insulin resistance. Individuals with a definitive diagnosis of chronic hepatitis C and insulin resistance were eligible for participation. Eligible participants were randomly assigned to the BCAA group or a control group. Participants were then crossed over to the other treatment for a further 12 weeks. Baseline clinical features, laboratory markers, fatty acid levels, and insulin sensitivity, assessed with oral glucose tolerance tests and a hyperinsulinemic euglycemic clamp, were also examined before and 12 and 24 weeks after the beginning of the study. Of the 27 patients who completed the study, 14 began in the BCAA group and 13 began as controls. There were no significant differences in glucose metabolism parameters or lipid profiles between the groups. HbA1c values were improved in 10 patients and worsened or remained unchanged in 17 patients. The only predictive variable for change in HbA1c was the baseline Matsuda index: the lower the index, the greater the improvement in HbA1c values. BCAA therapy did not have adverse effects on glucose tolerance or insulin sensitivity in patients with chronic hepatitis C and insulin resistance. Moreover, it had a therapeutic effect on HbA1c values in patients with marked peripheral (primarily muscle) insulin resistance. © 2012 Elsevier Inc

Macrocyclic peptide-based inhibition and imaging of hepatocyte growth factor.

金沢大学がん進展制御研究所Activation of hepatocyte growth factor (HGF) by proteolytic processing is triggered in cancer microenvironments, and subsequent signaling through the MET receptor is involved in cancer progression. However, the structure of HGF remains elusive, and few small/medium-sized molecules can modulate HGF. Here, we identified HiP-8, a macrocyclic peptide consisting of 12 amino acids, which selectively recognizes active HGF. Biochemical analysis and real-time single-molecule imaging by high-speed atomic force microscopy demonstrated that HiP-8 restricted the dynamic domains of HGF into static closed conformations, resulting in allosteric inhibition. Positron emission tomography using HiP-8 as a radiotracer enabled noninvasive visualization and simultaneous inhibition of HGF–MET activation status in tumors in a mouse model. Our results illustrate the conformational change in proteolytic activation of HGF and its detection and inhibition by a macrocyclic peptide, which may be useful for diagnosis and treatment of cancers.Embargo Period 6 month
