Filter by:The aim of this study is to compare surgical treatment of periodontal infrabony defects with and without the adjunct of an enemal matrix derivative (EMD) in terms of acute-phase responses, in systemic healthy patients.
Studying Pituitary adenylate cyclase-activating peptide 38 (PACAP38) induced headache effects on extra- and intracerebral arteries and pre-posttreated by sumatriptan and ketorolac assessed by magnetic resonance imaging (MRI) on healthy volunteers.
This is a single site, double-blind, randomized, crossover study designed to compare the effects of dietary supplementation with flax oil rich in alpha-linolenic acid (ALA) and fish oil rich in docosahexaenoic acid (DHA) on oxylipin profiles over time (0 to 4 weeks) and among obese females varying in their inflammatory state. Additional assessments will include plasma fatty acid composition, adipokines, markers of adipocyte dysfunction and inflammation; immune cell/monocyte fatty acid composition, and functional properties including their metabolism and oxylipin production; and vascular function.

Acute high-risk abdominal surgery (AHA) is performed in hospitals worldwide. Ethiologies are heterogeneous, but it carries a high mortality rate (1)(2). In particular, emergency laparotomies performed on elderly people has a high mortality rate(3)(4). Different quality improvement programs have been suggested, but the quality of care and mortality varies between hospitals (5)(6). The use of postoperative intensive care seem to be inadequate for this high risk population (1)(7)(8). It is of paramount importance to identify the frailest and acutely deranged patients, who are in risk of poor outcome, to allocate resources for optimization postoperatively. Failure to escalate care intensity after having developed postoperative complications affect outcome. Organization, teamwork and culture is important postoperatively to be able to escalate care especially in standard care wards (9)(10). However, it is difficult to predict which patients will develop complications. Different risk assessment tools have been proposed for patients undergoing AHA (11)(12). The APACHE-II score, even though developed for critical care, seems to give the best prediction of outcome. Objective risk assessment tools support clinical decision making as subjective clinical assessment often underestimates the risk for the patients in highest risk of complications and death (13). Good clinical decision-making is likely to improve the clinical outcome by allocating appropriate resources. Prognostic tools are also useful to inform patients about what to expect in the postoperative phase and of long-term outcome. Especially in the elder population with increased risk of loss of function or independency, this can be useful to give informed consent to treatment. Furthermore, good risk assessment is important to optimize palliative care after end-of-life decisions, which is often ignored in research, but highly relevant in clinical work. Prognostic biomarkers in other high mortality populations have received much attention for risk stratification (14). An ideal biomarker should be readily available upon decision-making, easy to measure, and reliable. Furthermore, it should accurately differentiate prognosis for patients to have value in the clinical decision-making and guide the treatment. It should also be linked to the clinical outcomes. The investigators aim to identify AHA biomarkers that are prognostic or predictive for postoperative morbidity, mortality and length of hospitalization.
The investigators plan to use amoxicillin in capsule form, prepared by a pharmacist, for antibiotic prophylaxis to decrease the failure rate of mini-screw implants temporarily placed in the palate of patients involved in Phase II orthodontics treatments. The mini-screws will be 8 mm long 1.7 mm diameter titanium screws manufactured by Forestadent and are commercially available and currently widely used in orthodontic treatment in both private practice and educational settings. Since antibiotic prophylaxis is considered the standard of care with traditional dental implants, the investigators believe that such prophylaxis will decrease the failure rate of orthodontic mini-screw implants also.
The primary function of epithelial tissues is to form a barrier between the body and the external environment, in order to protect the internal tissues from environmental stresses, by minimizing water loss and preventing the entry of pathogens, pollutants and allergens. Allergic disorders, such as atopic dermatitis, have been associated to an impaired epithelial barrier function. Indeed, defects in the epithelial barriers allow tissue-damaging factors to enter the tissue and thus activate the immune response. This study aims to establish a method to assess the epithelial barrier function in vivo by electrical impedance (EI) spectroscopy, a new technique for the characterisation of epithelial tissue. By this technique, a harmless electrical signal is sent through the skin and the response of the tissue is analysed, which is influenced by several cellular properties, such as shape, orientation and size. In order to validate this technique, skin of mice was treated with some molecules able to destroy the epithelial barrier. The investigators observed that, after damaging the barrier, a decrease of the EI can be detected, consistent with the type and degree of the damage. Based on this result, the investigators believe that this technique is a good candidate as an in vivo method to determine skin barrier defects, which might be used in the future as an early diagnostic tool for the prediction of the risk to develop atopic dermatitis in young subjects, allowing the possibility to apply in time possible preventive measures. In addition, this technique might be suitable for the evaluation of a given therapy during the hospitalisation. To confirm this hypothesis, in the present study patients with atopic dermatitis will be recruited. EI measurements will be performed in both lesional and non-lesional skin and values will be compared in order to detect any difference in the electrical response due to the inflammatory state. In addition, in order to evaluate whether these patients have an appreciable defect in their skin electrical behaviour, the investigators will compare non-lesional and lesional skin of patients with skin of healthy volunteers. Peripheral venous blood and skin biopsies will be collected, in oder to characterise several immune cell populations, to detect specific skin barrier mutations and to measure serum cytokines and immunoglobulins. These and some other parameters and will be analysed in order to identify a possible correlation with the EI.
The purpose of this study is to evaluate the efficacy of Saturno II association on the control of ocular inflammation post-phacoemulsification
In this study 45 patients undergoing weekly dialysis for chronic end stage renal disease will be enrolled. The patients will be treated with a standard dialysis solution, containing acetate buffer, for 3 months; subsequently the acetate will be substituted with citrate anion for the 3 following months and then, the last 3 months, the standard acetate-solution will be restarted. The aim of the study is to assess if acetate-to-citrate switch in the dialysis solution influences dialysis efficiency and patient inflammatory state.
The purpose of this study is to investigate the effects of egg intake on markers of HDL function and immune inflammation in healthy adults.
