BENEFICIAL EFFECT OF PROBIOTICS ADMINISTRATION IN INFLAMMATORY BOWEL DISEASE AND RELATED SPONDYLOARTHROPATHY: A PROSPECTIVE STUDY

2015

Background: Therapeutic treatment for inflammatory bowel disease (IBD) may follow different approaches, systemic as well as local, especially when the target is the osteoarticular apparatus. Although some clinical trials have suggested benefits from probiotics administration in IBD, there is still a great deal of controversy on their use. The aim of this study was to further investigate the effects of probiotics in patients with IBD and related spondyloarthropathy. Material/Methods: Fifty-nine patients affected by IBD with extra-intestinal involvement where evaluated from 2006 to 2010. Twenty-eight patients received administration of a standard therapy with mesalazine and 31 where treated w…

Management of Intra-abdominal Infections due to Carbapenemase-Producing Organisms.

2014

The prevalence of bacterial resistance to carbapenem antibiotics continues to increase because of bacteria producing metallo-β-lactamases (MBL), called carbapenemase-producing organisms (CPO). Enterobacteriaceae, which can be a common cause of intra-abdominal infections (IAIs), have become carbapenem-resistant Enterobacteriaceae (CRE). Updated international guidelines for the treatment of both IAIs and IAIs due to CRE have been published. Given the multifaceted nature of these infections, these recommendations have been jointly reviewed and endorsed by the Surgical Society and the Association of Medical Microbiology and Infectious Disease. The aims of this review are to summarize the genera…

Antibiotic resistance among Shigella serogroups isolated in Tehran, Iran (2002-2004)

2009

Shigellosis, one of the most common bacterial diarrhoeal diseases, is endemic throughout the world. It is one of the major causes of morbidity in children with diarrhoea in Iran [1-4]. Antibiotic therapy is useful and effective for shigellosis. Treatment is critical for persons with severe disease, particularly children and immunosuppressed patients. Use of an appropriate antibiotic therapy can shorten the duration of symptoms, significantly reduce the risk of transmission, and also prevent potentially lethal complications [5-7]. However, high frequencies of resistance in

A body weight loss- and health-promoting gut microbiota is established after bariatric surgery in individuals with severe obesity

2020

Obesity has reached an epidemic level worldwide, and bariatric surgery (BS) has been proven to be the most efficient therapy to reduce severe obesity-related comorbidities. Given that the gut microbiota plays a causal role in obesity development and that surgery may alter the gut environment, investigating the impact of BS on the microbiota in the context of severe obesity is important. Although, alterations at the level of total gut bacteria, total gene content and total metabolite content have started to be disentangled, a clear deficit exists regarding the analysis of the active fraction of the microbiota, which is the fraction that is most reactive to the BS. Here, active gut microbiota…

Analysis of Cerebral Vasospasm in a Murine Model of Subarachnoid Hemorrhage with High Frequency Transcranial Duplex Ultrasound

2021

Cerebral vasospasm that occurs in the weeks after subarachnoid hemorrhage, a type of hemorrhagic stroke, contributes to delayed cerebral ischemia. A problem encountered in experimental studies using murine models of SAH is that methods for in vivo monitoring of cerebral vasospasm in mice are lacking. Here, we demonstrate the application of high frequency ultrasound to perform transcranial Duplex sonography examinations on mice. Using the method, the internal carotid arteries (ICA) could be identified. The blood flow velocities in the intracranial ICAs were accelerated significantly after induction of SAH, while blood flow velocities in the extracranial ICAs remained low, indicating cerebral…

The effect of Dextransulfate 500 on the pathogenesis of herpes simplex virus infections in weanling mice

1978

Intraperitoneal (i.p.) injection of Dextran Sulfate (D.S.) 500 during a limited period of time influences the course of herpes simplex-virus-infections. D.S.500 was found to reduce the resistance of mice for some herpes simplex-virus strains (Len, L3-2s, Haase) if given between 16 hours before and 2 hours after i.p. infection. The decrease of resistance could be correlated with an increase of the virus content of liver, spleen, brain and spinal cord. Injection of herpes simplex-virus-specific immune serum counteracted the effect of D.S.500 on the course of infections. Conversely, D.S.500 increased the resistance of mice to another group of herpes simplex-viruses (strains D-316, Thea, DD), i…

Bacterial inactivation/sterilization by argon plasma treatment on contaminated titanium implant surfaces: in vitro study

2015

Background: Surface treatment by argon plasma is widely used as the last step of the manufacturing process of ti- tanium implant fixtures before their sterilization by gamma rays. The possibility of using such a technology in the daily clinical practice is particularly fascinating. The aim of the present study was to assess the effects of the argon plasma treatment on different titanium implant surfaces previously exposed in vitro to bacterial contamination. Material and Methods: Sterile c.p. titanium implant discs with turned (T, Sa: 0.8μm), sandblasted/acid-etched (SAE, Sa: 1.3μm) and titanium plasma sprayed (TPS, Sa: 3.0μm) surface were used in this study. A strain of Ag- gregatibacter a…

External evaluation of population pharmacokinetic models of vancomycin in neonates: the transferability of published models to different clinical set…

2013

Vancomycin is one of the most evaluated antibiotics in neonates using modeling and simulation approaches. However no clear consensus on optimal dosing has been achieved. The objective of the present study was to perform an external evaluation of published models, in order to test their predictive performances in an independent dataset and to identify the possible study-related factors influencing the transferability of pharmacokinetic models to different clinical settings. Published neonatal vancomycin pharmacokinetic models were screened from the literature. The predictive performance of 6 models was evaluated using an independent dataset (112 concentrations from 78 neonates). The evaluati…
