Filter by:The purpose of this study is to evaluate the safety,tolerability, pharmacokinetics and preliminary antitumor activity of sitravatinib as monotherapy and in combination with tislelizumab in participants with unresectable locally advanced or metastatic hepatocellular carcinoma or gastric/gastroesophageal junction cancer.
This case control study aims to determine whether spontaneous coronary artery dissection (SCAD) is associated with autoimmune diseases and to update the incidence of SCAD in a population-based cohort.
People who inject drugs (PWID) have increased risk of Staphylococcus aureus (S. aureus) colonization, skin and soft tissue infections (SSTI), and systemic infections like septicaemia and endocarditis. International research and data from Malmö needle exchange program (NEP) show a 60 - 70% lifetime SSTI prevalence. Longitudinal colonization pattern of S. aureus and its association with infection frequency among PWID is unknown. Cultures from the anterior nares, throat and perineum are used to indirectly assess S. aureus skin colonization. In PWID 28 - 45% are colonized in the nares, which increases risk of infections. Clinical significance of extra-nasal colonization, and persistent/intermittent colonization is uncertain. The S. aureus genome can be characterized by whole genome sequencing (WGS). Certain types are associated with abscesses and systemic infections. The infection pattern among PWID is unknown. S. aureus skin colonization level is decreased by chlorhexidine body wash and nasal mupirocin used as surgical prophylaxis and treatment of furunculosis. To our knowledge, disinfection effect on infections in PWID is not studied. However, the clinical impression is that severe infections have somewhat diminished since the NEP started distributing skin disinfectant tissues. RESEARCH QUESTIONS 1. Can repeated skin wash with chlorhexidine decrease infection frequency among PWID? 2. Is the longitudinal S. aureus colonization pattern associated with infection prevalence among PWID? 3. Can the risk of S. aureus-infections be predicted by quantification of bacterial level in anterior nares, throat, perineum or skin lesions/eczema? 4. Can different types of S. aureus be identified, that are associated with colonization or infection among PWID (by WGS)? METHODS AND TIME PHRAME Malmö NEP was established in 1986, and several studies assessing HIV, hepatitis and sociological questions have been conducted in this setting. In December 2016 continuous inclusion of 100 PWID for the actual study started at Malmö NEP. The study period is estimated to two years, with scientific papers expected for publication. During the first year of the study, mapping of S. aureus colonization pattern among all study participants is conducted by repeated sampling, clinical evaluation of eczemas, and interviews regarding infections. Every third month samples are collected from nares, throat, perineum and skin lesions. Semi quantification of S. aureus takes place at the microbiological research laboratory at Lund University. BBL CHROMagar Staph aureus-plates are used and incubated in 35oC air for 48h. S. aureus-colonies are identified and quantified manually by pink colour change and Pastorex. MALDI-TOF will be used in unclear cases. Disk-diffusion will be used for resistance determination. Bacterial isolates will be frozen to -70oC for later WGS. Intervention with chlorhexidine wash starts one year after inclusion for each study subject, and will continue for one additional year. Study participants with S aureus colonization will undergo regular showers with chlorhexidine (intervention group) at the needle exchange. In order to avoid bacterial resistance, muporicin will not be used. During the intervention, cultures, interviews and clinical evaluation will continue.
Computed tomography (CT) is the modality of choice to characterize pulmonary arteriovenous malformations (PAVMs) in patients with hereditary haemorrhagic telangiectasia (HHT). The objective of this study was to determine if CT findings were associated with frequency of brain abscess and ischaemic stroke. This retrospective study included patients with HHT-related PAVMs. CT results, PAVM presentation (unique, multiple, disseminated or diffuse), the number of PAVMs and the largest feeding artery size, were correlated to prevalence of ischaemic stroke and brain abscess.
In this observational study researchers want to learn more about changes in visual acuity (clarity of vision) with proactive flexible treatments over time in patients suffering from wet age-related macular degeneration (wAMD) after decision to treat with Aflibercept (Eylea) was made. Wet AMD is an eye disease that progressively destroys the macula, the central portion of the retina, impairing central vision.
CLINICAL PHASE 3 STUDY TO MONITOR THE SAFETY, TOLERABILITY, AND EFFICACY OF SUBCUTANEOUS HUMAN IMMUNOGLOBULIN (CUTAQUIG®) ADMINISTERED AT MODIFIED DOSING REGIMENS IN PATIENTS WITH PRIMARY IMMUNODEFICIENCY DISEASES
Laparoscopic sleeve gastrectomy operations performed for morbid obesity are among the most common methods in the world. Gastric or intestinal bypass surgery with or without sleeve gastrectomy is thought to be more effective in controlling both weight loss and metabolic diseases. For this purpose, Roux-en-y gastric bypass, transit bipartition, duodenal switch, jejunoileal bypass are performed. The aim of this study was to evaluate the effects of jejunoileal bypass surgery on weight loss and metabolic diseases in patients with sleeve gastrectomy.
This study aims to investigate the difference in the number of oocytes obtained by performing ovarian stimulation in follicular phase vs. luteal phase in a population of patients with previous suboptimal response. This is a controlled randomized clinical study. We aim to include 41 patients diagnosed with suboptimal response who will undergo an ovarian stimulation in order to vitrify and accumulate oocytes. The main variable for evaluating the efficacy in this exploratory study will be the number of oocyte cumulus complexes obtained.
The objective is to find if there is a relationship between the Fractal Dimension, the gap, vascular density (VD), the surface, the span ratio and the status of the choroidal neovessels to adjust the interval between 2 intravitreal injections nor on the qualitative aspect of Optical Coherence Structural Tomography but also on quantified quantitative and objective values.
A partially blinded randomised controlled non-inferiority trial comparing the efficacy, tolerability and safety of Triple ACTs artemether-lumefantrine + amodiaquine (AL+AQ) and artesunate- mefloquine+piperaquine (AS-MQ+PPQ) with the ACTs artemether-lumefantrine + placebo (AL+PBO) and artesunate- mefloquine + placebo (AS-MQ+PBO) (with single-low dose primaquine in some sites) for the treatment of uncomplicated Plasmodium falciparum malaria to assess and compare their efficacy, safety, tolerability.
