Filter by:Visceral leishmaniosis (VL) is widely reported in Ethiopia, with about 30% of cases being associated with human immunodeficiency virus (HIV). In absence of antiretroviral treatment (ART), poor prognosis, high mortality and high relapse rates are characteristic of Ethiopian VL patients with HIV co-infection. Conversely, co-infection can be successfully managed via a combination of effective treatment of the initial episode, timely ART and prevention of relapses. Actually, until cellular immunity returns with ART, the patient is at risk of VL relapses, which can result in death, severe illness, reduced ART efficacy, drug-resistance and possibly transmission of drug-resistant Leishmania donovani. Patients most vulnerable to relapses are those with high levels of immunosuppression, with previous VL episodes, or with opportunistic infections (OIs). The most important factor to prevent relapses seems to be the clearance of visible parasites. Limited studies in Europe show that HIV co-infected patients may benefit from secondary prevention with antimonials (part of mainstay treatment for VL in Ethiopia) and pentamidine (PM), not used for VL treatment in Africa. Such maintenance treatment has not been studied in African VL, but the poor outcomes without secondary prevention highlight a need of better care to patients at risk of relapse. This prospective cohort study aims at documenting the patient's outcomes of secondary prophylaxis with PM in VL-HIV co-infection, in terms of time to relapse or death, safety and feasibility, before it can be considered for general use in Ethiopia. A placebo group is not included, due to the clear advantages of the intervention to the patient population.
The primary objective of this pilot study is to examine the feasibility and acceptability of a randomized, controlled study of a mindfulness and values-based living intervention targeted at reducing fear of recurrence in breast cancer survivors compared to treatment as usual control. Furthermore, the secondary objective of this randomized, controlled pilot study is to determine preliminary efficacy and effect size of the mindfulness and values-based living intervention compared to the treatment as usual control condition in reducing fear of recurrence in breast cancer survivors.
Axillary lymph node dissection (ALND) was previously the standard axillary staging procedure in breast cancer patients. However, ALND is accompanied by a considerable morbidity, and sentinel lymph node biopsy (SLNB) evolved as a mean to decrease this morbidity. Between September 2000 and January 2004 breast cancer patients were included in the Swedish Sentinel Node Multicenter Cohort Study with the intent of studying axillary recurrence after negative SLNB for patients in which completion ALND were omitted. The patients were followed prospectively and events (local, regional and distant recurrences and deaths) were registered. The primary endpoint was axillary recurrence and secondary endpoints were disease-free, cancer-specific and overall survival.
This study will evaluate the feasibility of radiosurgery for all metastatic sites in patients presenting with oligometastatic disease, defined here as 5 or fewer sites of metastatic disease involving 3 or fewer organ systems.
This is a Prospective Phase II Study to evaluate Cord Blood Transplantation in Inherited or Acquired Severe Aplastic Anemia Refractory or in Relapse after Immunosuppressive Therapy in the absence of an HLA identical donor;
Title: HIOB - Hypofractionated Whole-Breast Irradiation preceded by Intraoperative Radiotherapy with Electrons as anticipated Boost ISIORT- 01 HIOB is defined as hypofractionated WBRT (40,5 Gy in 2,7 Gy per fraction) preceded by an Intraoperative Boost to the tumor bed ( 90 % reference dose of 10 Gy, 11,1 Gy Dmax IOERT). Primary endpoint is the proof of superiority of a new treatment regimen. The HIOB study concept is supposed to test the hypothesis whether such a combined schedule is superior (or iso-effective) towards "standard" RT in terms of local control and cosmetic outcome. In the vast majority of all publications, annual and 5 year in-breast recurrence rates following BCT showed a clear dependency on patient age within the following boundaries (primary references): Age > 50: Bartelink (standard): 0,7% (annual) 3,5% (5y) START B (best): 0,4 %(annual) 2,0% (5y) Age 41-50: Bartelink (standard) 1,2% (annual) 6,0% (5y) Whelan (best) 0,72%(annual) 3,6% (5y) Age ≥ 35-40 Bartelink (standard) 2% (annual) 10% (5y) Whelan (best) 0,72% (annual) 3,6% (5y) long these three different age groups, benchmarking will be performed against the best published results following 'Golden Standard'RT, usually defined as conventionally fractionated WBRT with 50 Gy (25 x2) plus external tumor bed boost with 10-16 Gy electrons (5-8x2Gy). Superiority is defined as going below the lower limit of the estimated 5 year local recurrence rate within the respective age group Inferiority is defined as crossing the respective upper limit . Secondary endpoint: Disease free survival Tertiary endpoint: toxicity assessment (acute and late) including long term cosmetic evaluation Study design and statistics: - Prospective multicenter single-armed - Sequential probability ratio test (SPRT) - Separate analysis within three different age groups Estimated Accrual time: strongly dependent on recruitment per year within the respective age group . Due to the statistical estimation of Szenario A and B the study will close after max. Time-period of 10 years in case of A or 6,4 years in case of B..

This prospective, multicentric single arm phase II study is based on the protocol of the international TARGIT-A study. The purpose is to investigate the efficacy of a single intraoperative radiotherapy treatment within elderly low risk patients (≥ 70 years, cT1, cN0, cM0, invasive-ductal) which is followed by WBRT only when risk factors are present. In presence of risk factors postoperative WBRT will be added to complete the radiotherapeutic treatment according to international guidelines.
T3 versus T4 as a primary treatment for palmer hyperhydrosis and effect on postoperative compensatory hyperhydrosis
Chronic pain may be a long-term problem after inguinal Lichtenstein hernioplasty. The aim of this study was to compare long-term results of hernioplasty using three different meshes (partly absorbable, lightweight polypropylene and thick polypropylene mesh).
This is a non-randomized two-part study of MK-4827 given with temozolomide in participants with advanced cancer. In Part A of the study, the dose-limiting toxicities (DLTs) and the maximum tolerated dose (MTD) of MK-4827 when combined with temozolomide will be found by increasing the MK-4827 dose level in successive cohorts. In Part B of the study, participants with advanced glioblastoma multiforme and advanced melanoma will be enrolled to further evaluate the tolerability and efficacy of the MK-4827 + temozolomide combination.
