Safety and efficacy of glecaprevir and pibrentasvir in north Tohoku Japanese patients with genotype 1/2 hepatitis C virus infection.

Background And Aims: To assess the efficacy and safety of treatment with glecaprevir/pibrentasvir in Japanese patients with genotype (GT) 1/2 hepatitis C virus (HCV) infection in a real-world clinical setting.

Methods: A total of 230 patients from 12 centers in northern Tohoku Japan with chronic hepatitis (CH) or compensated liver cirrhosis (LC) and GT1/2 HCV infection were treated with glecaprevir/pibrentasvir and followed up for 12 weeks after treatment completion. Those patients were evaluated by dividing them into the following three groups: CH GT1/2 HCV-infected, direct-acting antiviral agents (DAA)-naive patients received 8 weeks of treatment (8-week initial treatment group), compensated LC GT1/2 HCV-infected, DAA-naive patients received 12 weeks of treatment (12-week initial treatment group), and GT1/2 HCV-infected patients with previous failed DAA treatment were assigned to 12-week treatment (12-week re-treatment group).

In Situ Revascularization with a Rifampicin-Soaked Prosthesis to Treat Bare Iliac Artery Stent Infection: A Case Report.

Bare stent infection is an extremely rare complication of endovascular treatment. In such cases, surgical resection of the infected bare stent and revascularization are recommended; however, the revascularization strategy remains controversial. We present a case of a 78-year-old man with an infected aneurysm caused by a bare iliac artery stent infection.

Long-term outcome of partial resection in venous adventitial cystic disease.

Venous adventitial cystic disease is extremely rare. Therefore, standard treatment methods have not been clearly defined. Some reports suggest that complete cyst removal is an effective treatment.

The Real-world Efficacy and Safety of Ombitasvir/Paritaprevir/Ritonavir for Hepatitis C Genotype 1.

Objective There are few reports on the outcomes of 12-week paritaprevir, ombitasvir, and ritonavir (PTV/OBV/r) treatment in real-world clinical settings. We aimed to evaluate the efficacy and safety of 12-week treatment with ritonavir-boosted paritaprevir and ombitasvir in patients with hepatitis C virus (HCV) genotype 1 infection in a real-world setting. Methods Fifty-eight patients with chronic hepatitis or compensated hepatic cirrhosis and genotype-1 HCV infection were treated with PTV/OBV/r and followed for 24 weeks after the completion of treatment in 10 centers in northern Tohoku.

Beperminogene perplasmid for the treatment of critical limb ischemia.

Therapeutic angiogenesis for the treatment of ischemic disease can be attained through the delivery of recombinant growth factor proteins, through gene transfer or cell transplantation. Gene transfer associated with adenovirus or naked plasmid DNAs has been extensively studied in clinical trials. An investigational product, beperminogene perplasmid, is the naked plasmid DNA encoding the cDNA of human HGF, which has potent angiogenic activity.

[Retrospective analysis concerning AFP-producing gastric cancer].

The α-fetoprotein(AFP)-producing gastric cancer is a group of gastric cancers with poor prognosis because of its rapid growth and aggressive metastatic character. We examined AFP-producing gastric cancer in our department from 2008 to 2010. Of 12 patients studied, the median of the AFP level was 16, 038(96.

Wire-guided biliary cannulation technique does not reduce the risk of post-ERCP pancreatitis: multicenter randomized controlled trial.

Aim: To evaluate the effect of wire-guided biliary cannulation (WGC) on the prevention of post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP).

Methods: We investigated the impact of the WGC technique on the incidence of PEP by comparing the conventional cannulation (CC) technique in selective bile duct cannulation during ERCP with a cross-over design in a prospective multicenter randomized controlled trial and the potential risk factors for PEP. This involved six tertiary referral centers and three university hospitals.

The Effects of Percutaneous Endoscopic Gastrostomy on Quality of Life in Patients With Dementia.

Background: To examine the effects of percutaneous endoscopic gastrostomy (PEG) on quality of life (QOL) in patients with dementia.

Methods: We retrospectively included 53 Japanese community and tertiary hospitals to investigate the relationship between the newly developed PEG and consecutive dementia patients with swallowing difficulty between Jan 1st 2006 and Dec 31st 2008. We set improvements in 1) the level of independent living, 2) pneumonia, 3) peroral intake as outcome measures of QOL and explored the factors associated with these improvements.

Survival of geriatric patients after percutaneous endoscopic gastrostomy in Japan.

Aim: To examine the long term survival of geriatric patients treated with percutaneous endoscopic gastrostomy (PEG) in Japan.

Methods: We retrospectively included 46 Japanese community and tertiary hospitals to investigate 931 consecutive geriatric patients (≥ 65 years old) with swallowing difficulty and newly performed PEG between Jan 1st 2005 and Dec 31st 2008. We set death as an outcome and explored the associations among patient's characteristics at PEG using log-rank tests and Cox proportional hazard models.

Long-term outcomes after endoscopic sphincterotomy versus endoscopic papillary balloon dilation for bile duct stones.

Objective: Endoscopic sphincterotomy (ES) is a well-established standard method for treating common bile duct stones. However, biliary sphincter function is impaired after the treatment, and this may influence the long-term outcomes. In this study, we aimed to compare the long-term outcomes after ES with those after endoscopic papillary balloon dilation (EPBD) because the latter procedure is expected to preserve biliary sphincter function better than ES.

Endoscopic sphincterotomy and endoscopic papillary balloon dilatation for bile duct stones: A prospective randomized controlled multicenter trial.

Background: Endoscopic papillary balloon dilatation may be an alternative to endoscopic sphincterotomy in the treatment of bile duct stones. However, there is a controversy as to the effectiveness and safety of endoscopic papillary balloon dilatation.

Methods: Two hundred eighty-two patients with bile duct stones were enrolled and randomized to an endoscopic sphincterotomy or endoscopic papillary balloon dilatation group.

Transgenic mice overexpressing soluble osteoclast differentiation factor (sODF) exhibit severe osteoporosis.

Osteoclast differentiation factor, ODF, also called RANKL, TRANCE, or OPGL, is a key molecule for osteoclast differentiation and activation, and is thought to act as a membrane-associated molecule in bone remodeling. Recent study suggested that soluble ODF (sODF) released from T cells also has some roles in bone resorption. To investigate the physiological and pathological function of sODF, we generated two types of transgenic mice overexpressing sODF.

Effects of high salinity and constituent organic compounds on treatment of photo-processing waste by a sulfur-oxidizing bacteria/granular activated carbon sludge system.

To achieve practical treatment of photo-processing waste (PW) using our previously proposed sulfur-oxidizing bacteria (SOB)/granular activated carbon (GAC) sludge system, this paper elucidates why 3- to 5-X dilution of PW was required. That is, a series of experiments were carried out to show the effects of high salinity and constituent organic compounds in PW, respectively. Both an inorganic salts system and calcination PW system showed that SOB completely oxidizes S2O(3)2- -S to SO(4)2- -S even at 12.
