Prevention and control of nosocomial infections is one of the main pillars of security in each medical facility. This affects the quality of services and helps to minimize the economic losses incurred as a result of such infections. (Prolonged hospitalization, expensive antibiotic therapies, court costs of damages). Nosocomial infections occur in every medical facility in the hospitals in terms of risk of infection compared to other medicinal entities are at greater risk of environmental (number of hospitalizations for one bed, the amount of disinfectants, etc...

Ovarian cancer is a malignancy of high mortality rates. In respect of the number of deaths caused by cancers it occupies the fourth place among women in Poland. Recent studies are focusing on the role of immune system in ovarian cancer pathogenesis. It has been reported that immune response against ovarian cancer cells may be inhibited by a number of immunosuppressive mechanisms active in cancer microenvironment. It causes difficulties in recognizing and destroying cancer cells by immune system which leads to the development of immune tolerance and is associated with a low efficacy of standard therapeutic strategies...

INTRODUCTION: Comparing patient-reported outcomes such as urinary and erectile function across institutions is critical for prostate cancer research and quality assurance. Such comparisons are complicated by the use of different questionnaires. We aimed to develop a method to convert scores between four commonly used instruments. MATERIALS AND METHODS: Patient-reported data on urinary and sexual function were collected from 1,284 men with localized prostate cancer using the Expanded Prostate Index Composite (EPIC-26), UCLA Prostate Cancer Index (PCI), Sexual Health Inventory for Men (SHIM) and International Prostate Symptom Scale (IPSS) questionnaires...

BACKGROUND: Introduction of pneumococcal conjugate vaccine (PCV) has nearly eliminated vaccine-type (VT) invasive pneumococcal disease (IPD) in children, yet the reported resulting reduction of adult IPD is variable. We present the indirect impact of sequential PCV7/PCV13 implementation in Israel on adult IPD. METHODS: An ongoing nationwide active surveillance was initiated on July 2009 when PCV7 was implemented (with Catch-up). PCV7 was gradually replaced by PCV13 since November 2010...

Erionite is a zeolite representing a well-known health hazard. In fact, exposure of humans to its fibers has been unequivocally associated with occurrence of malignant mesothelioma. For this reason, a multi-methodological approach, based upon field investigation, morphological characterization, scanning electron microscopy (SEM)/energy-dispersive spectroscopy (EDS) chemical analysis, and structure refinement through X-ray powder diffraction (XRPD), was applied to different samples of potentially carcinogenic erionite from Northern Italy...

Influenza is a major cause of mortality and morbidity. We aimed to examine the influenza-associated hospitalization rates and proportions for cardiovascular disease (CVD) in tropical Singapore. Hospital admissions for ischemic heart disease (IHD), congestive heart failure (CHF), and overall CVD were obtained from the national inpatient database for the period of 2010-2014. We used, as the key indicator of influenza virus activity, the overall proportion of specimens from outpatients with influenza-like illness in the community that tested positive for influenza as part of the national influenza surveillance program...

Background: Zika virus is an emerging Flaviviridae virus, which has spread rapidly in the last few years. It has raised concern because it has been associated with fetus microcephaly when pregnant women are infected. The main vector is the mosquito Aedes aegypti , distributed in tropical areas. Methods: Niche modelling techniques were used to estimate the potential distribution area of A. aegypti. This was overlapped with human population density, determining areas of potential transmission risk worldwide...

As patients with end-stage renal disease are receiving renal allografts at older ages, the number of male renal transplant recipients (RTRs) being diagnosed with prostate cancer (CaP) is increasing. Historically, the literature regarding the management of CaP in RTR's is limited to case reports and small case series. To date, there are no standardized guidelines for screening or management of CaP in these complex patients. To better understand the unique characteristics of CaP in the renal transplant population, we performed a literature review of PubMed, without date limitations, using a combination of search terms including prostate cancer, end stage renal disease, renal transplantation, prostate cancer screening, prostate specific antigen kinetics, immunosuppression, prostatectomy, and radiation therapy...

The deregulation of p53 in cancer cells is one of the important factors by which cancer cells escape from the immune surveillance. Cholecystokinin (CCK) has strong bioactivity in the regulation of a number of cell activities. This study tests a hypothesis that CCK interferes with p53 expression to affect the apoptotic process in lung cancer (tumor) cells. In this study, tumor-bearing mice and A549 cells (a tumor cell line) were irradiated. The expression of CCK and p53 in tumor cells was assessed with RT-qPCR and Western blotting...

Cell growth and proliferative activities on titania nanotube arrays (TNA) have raised alerts on genotoxicity risk. Present toxicogenomic approach focused on epithelial HT29 cells with TNA surface. Fledgling cell-TNA interaction has triggered G0/G1 cell cycle arrests and initiates DNA damage surveillance checkpoint, which possibly indicated the cellular stress stimuli. A profound gene regulation was observed to be involved in cellular growth and survival signals such as p53 and AKT expressions. Interestingly, the activation of redox regulator pathways (antioxidant defense) was observed through the cascade interactions of GADD45, MYC, CHECK1, and ATR genes...

The oral mucosa is a critical barrier tissue that harbors a series of distinct immune cell subsets. Immune surveillance in the oral mucosa is important for both local and systemic immunity because the oral cavity is a heavily utilized route of pathogen entry and also serves as site of pathogen propagation. Nonetheless, composition and phenotype of the lymphocyte pool in the oral mucosa have remained poorly characterized. Utilizing a newly established protocol for mucosal immune cell isolation, here, we report that the oral mucosa features a unique cellular composition of immune cells, which differed not only from secondary lymphoid organs but also from mucosal tissues in the gut and lung...

Renal angiomyolipoma (AML) with the regional lymph node (LN) involved leads to a question of metastasis versus multicentric origin when their histology are similar. As the genomic instability is a common feature of cancer, we hypothesized that independently arising neoplasms in an individual patient would exhibit measurable genomic variation, facilitating the discrimination of tumor lineage and relatedness. Our study enrolled 12 patients who were diagnosed with nodal-involved renal AML at West China Hospital...

A fundamental mystery for dengue and other infectious pathogens is how observed patterns of cases relate to actual chains of individual transmission events. These pathways are intimately tied to the mechanisms by which strains interact and compete across spatial scales. Phylogeographic methods have been used to characterize pathogen dispersal at global and regional scales but have yielded few insights into the local spatiotemporal structure of endemic transmission. Using geolocated genotype (800 cases) and serotype (17,291 cases) data, we show that in Bangkok, Thailand, 60% of dengue cases living <200 meters apart come from the same transmission chain, as opposed to 3% of cases separated by 1 to 5 kilometers...

Indoleamine 2,3-dioxygenase 1 (IDO1) plays a key role in the immune system by regulating tryptophan levels and T cell differentiation. Several tumor types overexpress IDO1 to avoid immune surveillance making IDO1 of interest as a target for therapeutic intervention. As a result, several IDO1 inhibitors are currently being tested in clinical trials for cancer treatment as well as several other diseases. Many of the IDO1 inhibitors in clinical trials naturally bear structural similarities to the IDO1 substrate tryptophan, as such, they fulfill many of the structural and functional criteria as potential AHR ligands...

In Mexico, group A rotavirus (RVA) infections remain the most common cause of severe dehydrating diarrhea in children. This study was conducted to examine the circulating RVA strains in the northwest region of Mexico. RVA strains collected from stool samples of children were genotyped, and their partial sequences were analyzed. RT-PCR of the VP4 and VP7 genes showed the partial G9P[4] genotype in all the samples. Sequencing and phylogenetic analysis of the partial VP7 gene amplicons of 10 strains showed that they clustered in the RVA G9 lineage III, and 7 of them showed 100% identity with the reference strain LB1562, which was collected in the USA 2 years earlier...

Background: Streptococcus agalactiae (Group B Streptococcus, GBS) is a leading cause of meningitis, sepsis and pneumonia in neonates in the United States. GBS also causes invasive disease in older infants, pregnant women, children and young adults with underlying medical conditions, and older adults. Resistance to lincosamides in the absence of erythromycin resistance is rare in GBS, but has been previously reported in clinical isolates, both on its own or in combination with resistance to streptogramins A and pleuromutilins (L/LSA/LSAP phenotypes)...

The surveillance of (emerging) wildlife diseases can provide important, objective evidence of the circulation of pathogens of interest for veterinary and/or public health. The involvement of multiple research institutions in wildlife disease surveillance can ensure the best use of existing knowledge and expertise, but can also complicate or add challenges to the integration of wildlife disease surveillance components into a national programme. Documenting the existing efforts in a country's surveillance of wildlife diseases, including the institutes in which it takes place, provides a basis for policy-makers and authorities to identify gaps and priorities in their current surveillance programmes...
