Higher vedolizumab serum levels do not increase the risk of adverse events in patients with inflammatory bowel disease.

Although its mechanism of action may confer a safety benefit, vedolizumab has still been associated with adverse events (AE). We investigated whether inflammatory bowel disease (IBD) patients with higher trough vedolizumab serum levels experienced an increased risk of AEs. This was a retrospective study of 76 IBD patients with at least one measurement of serum vedolizumab available.

Cobalt chromium-layered double hydroxide, α- and β- Co(OH) and amorphous Cr(OH): synthesis, modification and characterization.

Cobalt-chromium layered double hydroxide (CoCr LDH), α- and β- Co(OH) and amorphous Cr(OH) have been synthesized under different reaction conditions. The obtained CoCr LDH was modified by stearic acid (SA) and sodium stearate (SS). The obtained samples have been characterized by X-ray diffraction (XRD), Scanning electron microscope (SEM), Ultraviolet-visible- (UV-Vis), Fourier transform infrared- (FTIR) and Energy-dispersive X-ray- (EDX) spectroscopy.

Magnetic nanocomposites based on phosphorus-containing polymers-structural characterization and thermal analysis.

Fabrication of magnetic nanocomposites containing iron oxide nanoparticles formed in situ within a phosphorus-containing polymer matrix as well as its structural characterization and its thermal degradation is reported here. Comparative structural studies of the parent polymer and nanocomposites were performed using FTIR spectroscopy, x-ray diffraction, and atomic force microscopy. The results confirmed the presence of dispersed iron oxide magnetic nanoparticles in the polymer matrix.

[Differential-diagnostic features of combined periapical lesions].

The paper describes specific correlation of the clinical and molecular pathogenic features in various types of combined periapical lesions. Endodontic apical lesions combined with periodontal disease are characterized by specific radiological signs, shifts in oral fluid physical and chemical properties, the disruption of nitrogen metabolism, increased iron concentration, collagen disruption and impaired concentration ratio of calcium and phosphorous. General depression of immunoglobulin synthesis and increased concentration of cortisol and estradiol in oral fluid are also typical features of combined periapical lesions.

[A comparative study of efficacy of 2-, 3- and 4-glass tests in patients with chronic prostatitis].

To compare informative value of three tests (2-, 3- and 4-glass) in diagnosis ofprostatitis we examined 177 patients with chronic prostatitis (CP) who were randomized into 4 groups. Group 1 patients (n = 33) were examined with standard 4-glass test (Mearls and Stamey), patients of subgroup 2a (n = 42) were examined with 2-glass test before finger rectal test (FRT), FRT was made in subgroup 2b (n = 45) before urine collection (2 portions), group 3 (n = 57) was examined by an original technique proposed by the authors. While performing the latter test special focus was given to urination continuity, then the secretion obtained at FRT was studied.
