There are about 9403 clinical studies being (or have been) conducted in Switzerland. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Clinicians are increasingly faced with the challenge of reconstructing the alveolar ridge as more patients desire fixed implant-supported restorations. Reconstruction of large horizontal alveolar defects still remains a challenge in implantology. Although autogenous blocks from intraoral sites are proven effective for such defects, donor site morbidity and limited graft availability are major limitations. Allogenic bone blocks have been proposed to overcome these limitations, however, the outcomes reported in the literature are inconclusive. In this case series, the efficacy of allogenic blocks for lateral augmentation of atrophic ridges was evaluated, over a three-year period. In nineteen edentulous sites from ten patients, cortico-cancellous allogenic blocks (PHOENIX, TBF, France) were shaped to the defect and screw-fixated. A double-layer of autogenous chips and demineralized bovine bone (Bio-Oss, Geistlich Pharma AG, Switzerland) was used to fill the voids. The augmented site was covered by non-cross-linked collagen membrane (Bio-Gide, Geistlich Pharma AG, Switzerland). After a healing period of 9 months, implants were placed and CBCT analysis was performed post-implantation. Following a period of 34 months of function (range 22 to 44 months), patients were clinically and radiographically re-examined.
SELECT 2 evaluates the efficacy and safety of endovascular thrombectomy compared to medical management alone in acute ischemic stroke patients due to a large vessel occlusion in the distal ICA and MCA M1 who have large core on either CT (ASPECTS: 3-5) or advanced perfusion imaging ([rCBF<30%] on CTP or [ADC<620] on MRI: ≥50cc) or both and are treated within 0-24 hours from last known well.
This is a single center cross-sectional retrospective study with a quantitative and qualitative approach (phase 1 and 2). In phase 1 an online survey will be realized and targets male cancer survivors. Phase 2 will take a qualitative approach, in which information about patient's experiences, needs and helpful support will be collected by establishing focus groups of cancer patients who had been diagnosed during the reproductive age. In the end, the results of this study will be integrated into the development of an online support tool concerning Fertility Preservation (FP).
This is a long-term, multi-center, longitudinal, observational study in children with achondroplasia (ACH). The aim is to study height velocity and comorbidities in children with ACH. This is a natural history study and no study medication will be administered.
This prospective study (including patients with an intertrochanteric or subtrochanteric fractures type 31A1, 31A2 and 31A3) is to assess the effect of an educational intervention for operating surgeons with respect to an improvement of the quality of reduction and internal stabilisation of intertrochanteric fractures. A historic cohort of patients operated at the University Hospital Basel for an intertrochanteric fracture from 2014-2015 will be used for comparison.
This cluster-randomized, multicenter trial is designed to investigate the effect of checklist-guided shared decision-making including decision aids and communication of expected outcome on patients' decision regarding their code status, and at the same time, if it improves decision-making quality as judged by patient's decisional comfort, patient knowledge and involvement in decision-making and patient satisfaction. Patients in whom resuscitation is considered as futile will be treated separately in an ancillary project. In these patients a checklist to communicate the futility and the medical consequences will be used.
The ultimate goal of this research is to develop a means to safely administer iron supplements to infants in settings with a high infection burden. The investigators will conduct a randomized clinical trial in 6 month-old Kenyan infants in conjunction with mechanistic microbiota studies using a novel long-term continuous polyfermenter platform inoculated with immobilized fecal microbiota from Kenyan infants. Oral iron supplements are associated with a significant 15% increase in the rate of diarrhea in children in malaria-endemic areas. The most recent studies have shown that prebiotic galacto-oligosaccharides (GOS) can provide partial amelioration of the adverse effects of iron supplementation by enhancing the growth of barrier populations of bifidobacteria and lactobacilli. The investigators hypothesize that the combination of GOS with bovine lactoferrin, adding iron sequestration as well as antimicrobial and immunomodulatory activities, will provide almost complete protection against the adverse effects of added iron on the intestinal microbiota.
Background: Major Depressive Disorder is one of the most prevalent mental illnesses, leading to substantial personal distress and economical consequences. Pharmacological Treatment is limited and relapse is frequent. Lysergic acid diethylamide (LSD) was extensively investigated in humans in the 1950s and 1960s and was shown to attenuate depressive symptoms. Clinical research with LSD ended in the 1970s due to regulatory restrictions but its use for personal and recreational purposes continued. In recent years, there has been a renewed interest in the use of hallucinogens in psychiatric research and practices, reconsidering LSD's antidepressant potential. Larger, well-designed and placebo-controlled studies are warranted. This study will evaluate the potential benefits of LSD-assisted psychotherapy in patients suffering from Major Depressive Disorder. Objective: To test the efficacy of LSD in patients with Major Depressive Disorder. Design: Randomised, double-blind, active-placebo-controlled trial using either two moderate to high doses of LSD (100 µg and 100 µg or 100 µg and 200 µg) as intervention and two low doses of LSD (25 µg and 25 µg) as active-placebo control. Participants: 60 patients aged > 25 years with Major Depressive Disorder (according to DSM-V). Main outcome measures: Change in depressive symptomatology (IDS, BDI), anxiety (STAI), and general psychopathology (SCL-90) compared with active-placebo-assisted psychotherapy.
The purpose of this study is to investigate the effects of a multidimensional stress prevention program on psychological and physiological indicators among university students.
Study 1 is to determine if muscle strength and dynamic and postural stability are compromised in patients with severe hip or knee Osteoarthritis (OA) and in patients after THA and TKA. Study 2 is to quantify the effect of THA and TKA on muscle strength and dynamic and postural stability.
