The aim of this study is to confirmed the role of intraoperative controlled release 5-Fluorouracil therapy in the prevention of recurrence after surgery for HCC patients with high risk of preoperative prediction of microvascular invasion.
Participants were examined using the methods reported previous. All chemical laboratory data were obtained at each clinic visit in the morning in a non-fasting state. A single specimen at each visit was used to assess urinary albumin levels based on the 2009 guidelines of the ADA. CBP was measured once in each clinic visit. HBP was measured every day in the morning within 10 minutes after awakening in the sitting position, but HBP value assessed for this study used the value measured once in the same morning at each clinic visit. Clinic hypertension (CH) and morning hypertension (MH) were defined as systolic BP (SBP) 130 mmHg and/or diastolic BP (DBP) 85 mmHg; clinic normotension (CN) and morning normotension (MN) were defined as SBP <130 mmHg and DBP <85 mmHg, respectively. The reason underlying that same threshold was used for both clinic and morning values was based on criteria of the 1999 WHO-International Society of Hypertension guidelines, because this study started in 1999. Based on HBP, subjects were divided into MH and MN patients, and anti-hypertensive drug use was determined in each group. In addition, based on CBP, subjects were divided into CH and CN patients. These patients were followed using the same methods used for MH and MN patients. Outcome considered only the first event in each subject. Primary end-point was death from any cause. Secondary end-points were new, worsened, or improved microvascular and macrovascular events. Risk factors related to each outcome were determined, and therapy which was added to baseline used for each disease in patients with MH was recorded at base- and end-points. All results are presented as means ± SD. Mean values were compared using the paired or unpaired student t test. To compare the prevalence of events or medical treatment in patients with and without HT on basis of HBP or CBP, Fisher's exact test with two-tailed P values was used, and then hazard ratio and 95% confidence intervals were calculated. Differences in outcomes between patients with HT and NT on basis of HBP or CBP at base- and end-points in the home or in the clinic, respectively, were assessed using Kaplan-Meier survival curves and then compared by hazard rate using the log-rank test. Risk factors determined to be statistically related to outcomes were assessed by Cox proportional hazard analysis.

Animal and human fear conditioning studies have repeatedly shown that administering propranolol before or after retrieval of a previously acquired fear results in an elimination of the fear expression. This approach, known as disruption of fear memory reconsolidation, is a promising new avenue for treating anxiety disorders. The present study aims to test its efficacy in patients with panic disorder.
The purpose of this study is to determine whether or not motivational interviewing is effective in smoking cessation at general practice setting in China.
The use of computed tomography (CT) screening has allowed for early detection of lung cancers as small as 5mm in diameter. Early stage cancers are highly curable with a reported survival of greater than 90% over 5 years after surgical resection. Before a patient can have surgery, a biopsy must be performed. One common method is a transthoracic needle biopsy (TTNB). In this procedure, a CT-image is used to locate the area for biopsy. Once identified, the radiologist applies a local anesthetic and inserts an aspiration needle through the ribs, and into the lung tissue. The sampled lung tissue is then sent to pathology. Although this procedure has a diagnostic yield ranging between 70% and 85%, it is associated with serious complications such as pneumothorax, hemoptysis, infection, hemothorax, air embolism and there is about a 20% (range 9%-54%) incidence of pneumothorax, or air leak from the lung, requiring chest tube drainage. Additionally, about 5-15% of cases experience hemoptysis, or coughing blood, although significant life-threatening hemoptysis is only present in less than 1% of patients. When these complications occur, hospitalization as inpatients is required, with an average length of stay of 1-3 days. A new form of technology to localize and biopsy peripheral lung lesions is believed to significantly reduce the amount of complications that can occur during a biopsy. This technology is known as Electromagnetic Navigation Bronchoscopy (ENB). ENB uses electromagnetic tracking and CT-generated virtual bronchoscopy to create a three-dimensional "GPS map" of the lung, guiding the surgeon directly to the tumor. The surgeon is then able to perform bronchoscopy and biopsy the tumor from inside the bronchus. A recent systematic review and meta-analysis of 15 trials reports a pneumothorax rate of 3.1%, with only 1.6% of patients requiring chest tube drainage. Initial studies demonstrate a slightly lower diagnostic yield for ENB as compared to TTNB; however, a systematic exploration of study heterogeneity reveal that lung nodules included in TTNB studies are larger than those included in the meta-analysis of ENB yield. The review further identified six variables associated with increased diagnostic yields for ENB, including "combined use of an ultrasonic radial probe and catheter suctioning as a sampling technique". The superDimension® InReach™ System was granted Health Canada approval on July 23, 2009. There have been no studies directly comparing ENB to TTNB, either retrospectively or prospectively. Initial systematic reviews demonstrate that ENB may have a slightly lower diagnostic yield relative to TTNB. Selection bias and low study quality may have resulted in an underestimation of the true diagnostic yield associated with ENB. The literature also confirms that ENB has a significantly better safety profile as compared to TTNB. As such, a prospective comparison between the two techniques is mandated. This Phase II pilot feasibility trial will utilize randomized methodology to gather the preliminary data that is required for the successful completion of a Phase III randomized controlled trial to compare lung biopsy with ENB verses TTNB. This study will also be the first time ENB lung biopsy is documented in Canada.

Uterine cavity diseases can cause mild to severe symptoms, and may indicate the functional problems of the female reproductive system. Many articles examine the efficacy of diagnostic hysteroscopy compared to sonohysterography in the diagnosis of uterine cavity diseases. Most of the articles are from the last decade, but the subject has been laid aside in the recent years. Antonio Simone Lagana and his group have found that there is 100% correlation in uterine cavity structure between diagnostic hysteroscopy and sonohysterography, and only 78% correlation when it comes to intrauterine fibroids and polyps. Walid El-Sherbiny, MD and his group have found that there is a significant advantage to three-dimensional sonohysterography over two-dimensional in the diagnosis of uterine cavity diseases. No significant difference was observed, and 97% correlation was found, comparing three-dimensional sonar and hysteroscopy. Work rationale is that there is a reason to reconsider the status of the diagnostic hysteroscopy to sonohysterography due to evolving technologies, and an improvement in resolution and three dimensional technologies.
Induction of labor is one of the most common obstetrical medical procedures performed today. Iatrogenic stimulation of uterine contractions prior to the onset of spontaneous labor is undertaken for various maternal and fetal indications and spans 20% of deliveries today. 1. During the past years there has been an additional rise due to elective inductions 2. Induction is undertaken when potential risks of prolonging pregnancy outweigh the risks of induced delivery, particularly those associated with post-term pregnancy, rupture of membranes, oligohydramnios and additional fetal and maternal conditions that pose risks to mother and fetus. In many circumstances of women with an unfavorable cervix (Bishop score of 7 or less) sequential induction with more than one agent is necessary. To date, no trial has compared the optimal subsequent ripening method after the preliminary use of dinoprostone (prostaglandin E2). In this trial investigators aim to compare the obstetrical outcomes of subsequent induction in women admitted for induction of labor with Bishop score <7 or less 24 hours after the insertion of vaginal prostaglandin insert (Propess). Two methods of routine induction of labor will be compared: An additional Propess induction for another 24 hours vs. intravenous oxytocin infusion combined with intra-cervical balloon insertion.
