Background Complex interactions between the brain, gut and adipose tissue allow to recognize obesity as a neurometabolic disorder. The recent data have shown that gut microbiota can play a potential role in obesity development. Transcranial direct current stimulation (tDCS) is a safe and non-invasive technique to modulate the activity of cerebral cortex and other connected brain areas also in context of appetite control. The objective of this study was to evaluate the effects of repetitive anodal tDCS (AtDCS) of prefrontal cortex on feeding behavior, metabolic status and selected phyla of gut microbiota in rats with obesity induced by high-calorie diet (HCD). Methods 32 female Wistar rats were equally divided into 4 subgroups depending on diet effect (lean versus obese) and type of stimulation (active versus sham tDCS versus no stimulation). Feed intake, body weight, blood lipoproteins and leptin levels as well as Firmicutes and Bacteroidetes in intestines and stool were examined. Results HCD changed feeding behavior and metabolic parameters typically for obesity-related ranges and resulted in an abundance of Firmicutes at the expanse of Bacteroidetes in the large intestine and stool. AtDCS decreased appetite, body weight, and cholesterol levels. In addition, AtDCS reduced ratio of the average number of Firmicutes to average number of Bacteroidetes in all examined tissues. Conclusions Repetitive AtDCS is not only effective for appetite restriction but can also modulate gut microbiome composition which demonstrates the existence of the brain–gut–microbiome axis and points at this technique as a promising complementary treatment for obesity. However, the effects should be further replicated in human studies.

Genital tract ureaplasma infections are associated with numerous complications, ranging from inflammation, through infertility, to problematic pregnancy. In the course of ureaplasma infection, the risk of human papillomavirus infection increases. Diagnostic tests for urea-plasma infections are not always carried out, especially in women with the normal Nugent test results. The study attempts to check whether it is possible to find a prognostic indicator that could suggest a high abundance of ureaplasmas (≥ 104 CFU/ml) at the stage of the initial examination of vaginal discharge. Such a prognostic factor could qualify women for further tests to detect infections with these atypical bacteria. Six hundred twenty-seven white women with a score of 0–3 on the Nugent scale were tested, including 322 patients with a high abundance of ureaplasmas (≥ 104 CFU/ml) and 305 who tested negative for these bacteria. Ureaplasma infections were detected statistically significant in women who had few or no epithelial cells in the genital swab specimens compared to the results obtained for women with numerous or very numerous epithelial cells (p < 0.001). The risk of the high density of ureaplasmas was 38.7% higher with fewer or no epithelial cells than with high numbers. In patients aged 18–40 years with few or no epithelial cells, a high density of ureaplasmas (≥ 104 CFU/ml) was observed significantly more frequently (p = 0.003). Determining the number of epithelial cells in Gram-stained slides may be the prognostic indicator of ureaplasma infection. Testing for genital ureaplasma infection should be considered, especially in women of childbearing age (18–40 years), even if the Nugent test value is normal and pH ≤ 4.6.

Scabies is the skin infestation caused by Sarcoptes scabiei var hominis. It is one of the commonest dermatological infection which can affect people around the world. However, nails are relatively rarely involved, and the fingernails are mostly infected. The report a case of a 77-year-old woman, long-term pensioner of a nursing home, who had isolated toe subungual Sarcoptes infestation. In addition, the results of systematic review of toenails scabies was presented. Analysis of 21 subungual Sarcoptes infestation cases, revealed that patients in any age (median age 45+/-31.7-year-old) and sex can be affected. Most of the patients had concomitant diseases. Seventy-five percent of cases of nail involvement were treated with combined or sequential therapy. The most used drugs were ivermectin (IVR) and permethrin (PER) (each used in 47.6% cases), following γ-BHC (38.1%) and crotamiton (CRO) (23.8%). It seems that the crucial for adequate diagnosis in scabies affected nails is a precise anamnesis, early and accurate diagnosis that consists of examining not only skin lesions, but including assessing toenails, and differentiation of Sarcoptes infestation from other nail diseases as onychomycosis or psoriasis. Important to achieving a cure is at least frequent nail trimming, softening the nail plate with urea or in the difficult cases the mechanical removal of subungual plaque with using of a scabicide in the location allowing to penatrate it under the nail plate.

Background/Objectives: The genus Acinetobacter demonstrates resistance to antibiotics and has been shown to spread in the hospital environment causing epidemic outbreaks among hospitalized patients. The objectives of the present study was to investigate the antibiotic resistance, biofilm formation, and clonality among Acinetobacter baumannii strains. Materials and Methods: The study involved 6 (I Outbreak) and 3 (II Outbreak) A. baumannii strains isolated from patients hospitalized in vascular surgery unit. Results: All tested A. baumannii strains were extensively drug resistant (XDR) and all the isolates were carbapenem-resistant and among them, all carried the blaOXA-51 gene, the blaOXA-24 gene, as well as the blaOXA-23 gene. All of the investigated strains had the ability to form a biofilm, but all of them produced less biofilm than the reference strain. Multi-locus sequence typing (MLST) showed that all strains belonged to the ST2 clone. Pulsed-field gel electrophoresis (PFGE) divided the tested outbreak strains into two clones (A and B). Conclusion: This study shows a nosocomial spread of XDR A. baumannii ST2 having the blaOXA-51 gene, the blaOXA-24 gene, as well as the blaOXA-23 gene, low biofilm formers, that was prevalent in the vascular surgery unit. To identify the current situation of vascular surgery departments targeted epidemiological investigation was needed. Effective implementation of infection control prevented the spread of the epidemic outbreaks.

Background Conventional brackets are often used during orthodontic therapy patients with malocclusion. Nevertheless, their complicated construction greatly inhibits oral hygiene, which predisposes to the increased carriage of the microbiota. It seems that orthodontic brackets could be a reservoir of yeast and predisposing to develop oral candidosis. Objectives The aim of this study was to assess changes in Candida species prevalence and periodontal parameters after orthodontic brackets placement in patients who received oral hygiene instruction; to determine role of elastic ligatures in those changes; to characterize isolated yeasts according to their ability to biofilm formation. Patients/Methods 17 participants (average age 17±7 years) have been monitored by taking oral rinses, elastomeric ligatures samples and evaluation of API and GBI Indexes before and after placement of orthodontic conventional brackets for 12 weeks. Isolated yeasts was counted and used to the biofilm formation assay. Results 116 samples (67 oral rinses and 49 orthodontic elastomers) were collected. 51% of patients were carriers of Candida in which C. albicans was the most common species. The average number of colonies (CFU/ml) obtained from oral rinses showed an upward trend depending on duration of the study and some correlation with periodontal indexes (API, GBI) was found. One third of the analysed strains have shown ability to form greater biofilm than control strain. Conclusions Orthodontic ligatures surface permit biofilms creation and orthodontic brackets change dynamic oral microbiota. Maintaining proper oral hygiene is crucial for every orthodontic patient.

Background Conventional brackets are often used during orthodontic therapy of patients with malocclusion. The complex construction of such brackets greatly inhibits oral hygiene, which predisposes to increased carriage of microbiota. Orthodontic brackets could act as reservoir of yeast and predispose to oral candidosis. The aim of this study was to assess Candida prevalence and the role of oral hygiene during fixed appliance therapy. A further aim was to characterize the isolated yeasts according to their ability to form biofilms. Methods Seventeen participants (average age 17 ± 7 years) were monitored by taking oral rinses and elastomeric ligature samples, and by evaluating the approximal plaque index (API) and gingival bleeding index (GBI) before and after placement of the orthodontic conventional brackets for 12 weeks. Isolated yeasts were counted and biofilm formation was evaluated. Results One hundred and sixteen samples (67 oral rinses and 49 orthodontic elastomers) were collected. Ten patients (58.8% subjects) were Candida-carriers (two were colonized after bracket placement) and C. albicans was the most common species. The average number of yeasts in the oral cavity showed some fluctuation during the study, but in general had an upward trend (adj. R2 = 0.7967, p = 0.07025). A correlation was found between median number of yeasts and the periodontal indices (API, GBI). The average API values decreased in the Candida-carriers (adj. R2 = 0.95; p = 0.01709), while average GBI values increased in the noncarriers (adj. R2 = 0.92; p = 0.0256). Conclusions Treatment with orthodontic appliances promotes Candida yeast colonization, which is variable over time in terms of strain and species, with dominance of C. albicans, and without increased biofilm-forming activity. The API value decreases over time in carriers, and the GBI value increases in uncolonized patients, which may have predictive significance for the development of oral candidiasis during orthodontic treatment.

Drug-resistant bacteria from the genus Enterococcus are currently among the most important pathogens behind healthcare-associated infections. The drug resistance of these bacteria has been on the increase since the 1980s, leeding to their multi-drug resistance. Selective pressure, present mainly in the hospital environment, contributed to this phenomenon. However, also outside the hospital environment selective pressure comes into play, namely the use of antibiotics as promoters of growth in animal husbandry and in food production. Household pets form a reservoir of drug-resistant enterococcal strains, too. The exchange of resistance genes between enterococcal strains from different niches poses a threat to public health. 1.

Vancomycin-resistant Enterococcus faecium (VREfm) strains have become an important hospital pathogen due to their rapid spread, high mortality rate associated with infections and limited therapeutic options. Vancomycin resistance is predominantly mediated by VanA or VanB phenotypes, which differ as regards maintaining sensitivity to teicoplanin in the VanB phenotype. The majority of VREfm cases in the United States, Europe, Korea, South America and Africa are currently caused by the VanA phenotype. However, the epidemics in Australia and Singapore are chiefly brought about by the VanB phenotype. The rate of VREfm isolate spread varies greatly. The greatest percentage of VREfm is now recorded in the USA, Ireland and Australia. Supervision of VRE is implemented to varying degrees. Therefore, the epidemiological situation in some countries is difficult to assess due to limited data or lack thereof.
