Official title: LAPAD - A prospective study on the effect of adhesiolysis during elective laparotomy or laparoscopy on per- and postoperative complication, quality of life and socioeconomic costs Background: With improved surgical technology and ageing of the population the number of reoperations in the abdomen dramatically increases. The risk for a repeat laparotomy or laparoscopy is a high as 30% in the first ten years after a laparotomy. In over 95% of reoperations adhesiolysis is required to gain access to the abdominal cavity and operation area. Adhesiolysis significantly increases the risk for inadvertent organ damage, such as enterotomies, leading to higher morbidity, mortality and socioeconomic costs. Purpose: To define the impact of adhesiolysis on per- and postoperative complications, quality of life and socioeconomic costs. Design: Prospective observational study. Primary outcomes: - adhesiolysis time - inadvertent enterotomy - seromuscular injury - miscellaneous organ damage - Serious adverse events of operation (anastomotic leakage, delayed diagnosed perforation, wound infection, abdominal infection, haemorrhage, pneumonia, urinary tract infection, abscess, fistula, sepsis, death) Secondary outcomes: - Hospital stay - Intensive care admission - Reinterventions - In-hospital costs - Parenteral feeding - Short term readmissions (30 days) - Quality of life (Gastro- intestinal tract complaints, Short Form- 36(SF-36), DASI (Duke Activity Score Index(DASI) ) Estimated enrollment: 800 start study: 1 june 2008 Inclusion completion date: 1 june 2010 Estimated study completion date: 1 february 2011
Malaria is one of the major infectious diseases in the world with a tremendous impact on the quality of life significantly contributing to the ongoing poverty in endemic countries. It causes almost one million deaths per year, the majority of which are children under the age of five. The malaria parasite enters the human body through the skin, by the bite of an infected mosquito. Subsequently, it invades the liver and develops and multiplies inside the hepatocytes. After a week, the hepatocytes burst open and the parasites are released in the blood stream, causing the clinical phase of the disease. As a unique opportunity to study malaria immunology and efficacy of immunisation strategies, a protocol has been developed in the past to conduct experimental human malaria infections (EHMIs). EHMIs generally involve small groups of malaria-naïve volunteers infected via the bites of P. falciparum infected laboratory-reared Anopheline mosquitoes. Although potentially serious or even lethal, Plasmodium falciparum (P.falciparum) malaria can be radically cured at the earliest stages of blood infection where risks of complications are virtually absent. The investigators have shown previously, that healthy human volunteers can be protected from a malaria mosquito challenge by immunization with mosquito-bites under chloroquine prophylaxis (CPS immunization). However, it is unknown whether this protection is based on immunity directed towards the liver- or the blood stage of the disease. For future development of vaccines and understanding of protective immunity to malaria, it is important to investigate at which level protective immunity is generated by CPS immunization. Therefore, we aim to investigate whether CPS immunization confers protection to a blood-stage challenge.

This randomized, multi-center, double-blind, parallel-group, placebo-controlled study will evaluate the efficacy and safety of RO4917838 (bitopertin) in patients with sub-optimally controlled symptoms of schizophrenia. Patients, on stable treatment with antipsychotics, will be randomized to receive daily oral doses of RO4917838 or matching placebo for 52 weeks, followed by an optional treatment extension for up to 3 years.
A Multicentre study comparing 5 different Self-Monitoring Of Blood Glucose (SMBG) system commercially available in Germany & Holland.
This study is a large observational study, set-up to observe how long-term treatment with FIRMAGON (hormone regulator) compare to other treatments in regards to cardiovascular events, changes in bone density, changes in blood sugar levels or liver enzyme levels in subjects with prostate cancer. Subjects will be treated according to their routine clinical care and not dictated by the study. As the study is observational in nature, the study will collect data relating to the events specified above. Subjects that agree to this study will be followed-up for 5 years. Subject data will be collected every 3 months for the first 2 years and every 6 months for the last 3 years.
This is a Phase 3 randomized, double blind, placebo controlled study of tasquinimod in asymptomatic to mildly symptomatic patients with metastatic CRPC to confirm the effect of tasquinimod on delaying disease progression compared with placebo. Approximately 1200 eligible patients with metastatic CRPC will be randomly assigned in a 2:1 ratio to 1 of 2 treatment groups: Treatment Group A (tasquinimod 0.25, 0.5, or 1 mg/day; n=800) or Treatment Group B (placebo; n=400).
In this project the main focus is on assessing sexual functioning and the quality of sexual life after the treatment of colorectal cancer in patients and their partners. Patients and their partners complete questionnaires concerning sexual functioning, quality of life, body image, fatigue, anxiety, depressive symptoms, personality factors, and demographic factors. Questionnaires are completed before surgical treatment, 6 weeks, 3 months, 6 months, and 12 months after diagnosis. The results of this prospective study will give insight in 1) the incidence of sexual problems and the extent patients with colorectal cancer and their partners are bothered by these problems across time, 2) the effect of different treatment modalities on sexual functioning, 3) the relation between sexual problems and quality of life, 4) the determinants of sexual problems and the quality of sexual life adopting the biopsychosocial approach of patients with colorectal cancer who have been treated with surgery, radiation and/or chemotherapy, and more specifically to the role of personality and patient factors and sexual functioning/the quality of sexual life.
The AVIS Study is a retrospective multicenter international study that aims to answer a series of questions on the use and performance of adrenal venous catheterization (AVS) for the diagnosis of primary hyperaldosteronism subtype. A questionnaire will be circulated among the centres that are internationally recognized and have published in the field of AVS and have agreed to participate in the study. The first aim of the AVIS study is to collect summary data on how AVS is being performed throughout the world to answer the following questions: - How many AVS studies haw been performed yearly from 2005 to 2010 at each center? - How many adrenal vein ruptures occurred during the AVS at each center?Has the rate of adrenal vein rupture been steady or has it changed over the 5 years? - How many centers use bilaterally simultaneous and how many use sequential AVS catheterization? - How many radiologists perform AVS at each center? - How many centers use a cosyntropin stimulation during AVS? - What is the percentage of PA patients in whom AVS is performed? - How many centres calculate the selectivity index? What is the minimum cutoff used? - How many centers calculate the lateralization index? What is the minimum cutoff used? - Are the AVS studies that are not bilaterally selective used for diagnosis? - How many centers calculate the controlateral suppression index and what is the minimum cutoff used? - What is the cost of AVS for the National Health System or Insurance and for patients? The second aim of the study is to calculate the rate of AVS studies that are selective and show lateralization of aldosterone excess at each center by applying predefined set of criteria for defining selectivity and lateralization. Data on the final diagnosis of the PA subtype will be gathered and used as reference to assess the performance of AVS using receiver operating characteristic curves analysis and the Youden index to determine the optimal cutoffs. A worksheet will need to be completed providing information on the following: Demography; Date of AVS;Baseline blood pressure (BP) values and serum K+;Dynamic test during the AVS if any; plasma aldosterone and cortisol concentration in the infra-adrenal inferior vena cava and in the right and left adrenal vein; diagnosis of PA subtype; treatment (adrenalectomy or pharmacological therapy); post-treatment BP and serum K+ values; concordance/discordance between imaging (CT or RM) and AVS.
