BACKGROUND Surgical site infections (SSIs) following colorectal surgery (CRS) are among the most common healthcare-associated infections (HAIs). Reduction in colorectal SSI rates is an important goal for surgical quality improvement. OBJECTIVE To examine rates of SSI in patients with and without cancer and to identify potential predictors of SSI risk following CRS DESIGN American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) data files for 2011-2013 from a sample of 12 National Comprehensive Cancer Network (NCCN) member institutions were combined...

Porcine reproductive and respiratory syndrome virus (PRRSV) is a problematic virus that is difficult to control. The principal target cells for PRRSV infection are porcine alveolar macrophages (PAMs). Increasing evidence has demonstrated that CD163 is the determinant receptor for PRRSV infection. However, the relationship between CD163 abundance and PRRSV infection is unclear. In this study, we first generated primary immortalized PAMs (iPAMs) using SV40 large T antigen and demonstrated that CD163 expression is suppressed by the alternative splicing of mRNA in iPAMs...

Epidemiological studies indicate an inverse correlation between the prevalence of the so-called western diseases, such as obesity and metabolic syndrome, and the exposure to helminths. Obesity, a key risk factor for many chronic health problems, is rising globally and is accompanied by low-grade inflammation in adipose tissues. The precise mechanism by which helminths modulate metabolic syndrome and obesity is not fully understood. We infected high fat diet (HFD)-induced obese mice with the intestinal nematode parasite Heligmosomoides polygyrus and observed that helminth infection resulted in significantly attenuated obesity...

Hepatitis E virus (HEV) is associated with acute hepatitis disease. Numerous truncated HEV capsid proteins have been successfully expressed using different expression systems. Among these, p495, a protein truncated at its N- and C-termini by 111 and 54 amino acids (aa), respectively (HEV ORF2 aa 112-606) can self-assemble into T = 1 virus-like particles (VLPs) when expressed by insect cells. A shorter p239 (aa 368-606) protein is a particulate antigen that we have previously used in our commercialized HEV vaccine, Hecolin...

Tuberculosis still remains one of the most common, communicable, and leading deadliest diseases known to mankind throughout the world. Drug-resistance in Mycobacterium tuberculosis which threatens to worsen the global tuberculosis epidemic has caused great concern in recent years. To overcome the resistance, the development of new drugs with novel mechanisms of actions is of great importance. Imidazole-containing derivatives endow with various biological properties, and some of them demonstrated excellent anti-tubercular activity...

Background: Environmental cleaning is a fundamental principle of infection control in health care settings. We determined whether implementing separated environmental cleaning management measures in MICU reduced the density of HAI. Methods: We performed a 4-month prospective cohort intervention study between August and December 2013, at the MICU of Cathay General hospital. We arranged a training program for all the cleaning staff regarding separated environmental cleaning management measures by using disposable wipes of four colors to clean the patients' bedside areas, areas at a high risk of contamination, paperwork areas, and public areas...

BACKGROUND: The highly pathogenic porcine reproductive and respiratory syndrome virus (HP-PRRSV) has been responsible for several viral attacks in the Asian porcine industry, since the first outbreak in China in 2006. During the early stages of the HP-PRRSV infection, high levels of proinflammatory cytokines are noted in the host peripheral blood, which are accompanied by severe lesions in the lungs and immune system organs; these are considered as the greatest contributors to the overall disease burden...

Background: Hospital-acquired infections (HAIs) are an important cause of morbidity and mortality. This study examined the epidemiology, clinical outcomes and microbiological profile of HAIs. Methods: This prospective study was carried out on patients identified to have developed HAIs while admitted to the medical wards, surgical wards, dialysis unit and intensive care unit (ICU) of the hospital. Patients were recruited consecutively until the target study population was reached...

Cysticercosis refers to a parasitic infection caused by the larvae of pork tapeworm Taenia solium . It is a parasitic zoonosis and listed by the World Health Organization (WHO) as one of the neglected tropical diseases. Cysticercosis is spreading all over the world through globalization and it mainly epidemic in developing countries. In the southwest and minority nationality areas of China, as a result of the low level of medical and health care, and the unchangeable diet custom, there are still many cases of cysticercosis, which is manifested as a local high prevalence...

BACKGROUND: The Human T-Lymphotropic Virus type 1c subtype (HTLV-1c) is highly endemic to central Australia where the most frequent complication of HTLV-1 infection in Indigenous Australians is bronchiectasis. We carried out a prospective study to quantify the prognosis of HTLV-1c infection and chronic lung disease and the risk of death according to the HTLV-1c proviral load (pVL). METHODOLOGY/PRINCIPAL FINDINGS: 840 Indigenous adults (discharge diagnosis of bronchiectasis, 154) were recruited to a hospital-based prospective cohort...

Zika virus (ZIKV) infection has become a global public health concern. The viral NS2B-NS3 protease is an attractive antiviral target because of its role in maturation of viral non-structural proteins. Substrate-derived protease inhibitors have been investigated, but it remains challenging to develop them into drugs. Small-molecule inhibitors are of great interest in antiviral drug development. Here we report the structure and dynamics of ZIKV NS2B-NS3 protease covalently bound to a small-molecule inhibitor...

Damage to the endothelial glycocalyx is a critical factor in increased pulmonary vascular permeability, which is the basic pathological feature of acute respiratory distress syndrome (ARDS). Neferine (Nef), a bisbenzylisoquinoline alkaloid isolated from green seed embryos of Nelumbo nucifera Gaertn , has extensive pharmacological activity. In this study, we showed that Nef reduced lung-capillary permeability, down-regulated the production of cytokines (IL-1β, IL-6, TNF-α, and IL-10) and inhibited the activation of the NF-κB signaling pathway in mice with lipopolysaccharide (LPS)-induced ARDS...

NADC30-like porcine reproductive and respiratory syndrome virus (PRRSV) causing clinical disease outbreaks has been recently reported in China. The recombination occurring among PRRSV strains could lead to the emergence of novel and more virulent viruses. In our previous study, a novel recombinant type 2 PRRSV (TJnh1501) between NADC30-like and modified-live virus (MLV)-like derived from the Chinese highly pathogenic PRRSV was shown to have higher pathogenicity than NADC30-like PRRSV. It remains unknown whether the emergence of the novel recombinant PRRSV strain can lead to variable protection efficacy of the MLV vaccines...

Elderly people are at high risk for influenza-related morbidity and mortality due to progressive immunosenescence. While toll-like receptor (TLR) agonist containing adjuvants, and other adjuvants, have been shown to enhance influenza vaccine-induced protective responses, the mechanisms underlying how these adjuvanted vaccines could benefit the elderly remain elusive. Here, we show that a split H1N1 influenza vaccine (sH1N1) combined with a TLR4 agonist, glucopyranosyl lipid adjuvant formulated in a stable oil-in-water emulsion (GLA-SE), boosts IgG2c:IgG1 ratios, enhances hemagglutination inhibition (HAI) titers, and increases protection in aged mice...

Surveillance and feedback of infection rates to clinicians and other stakeholders is a cornerstone of healthcare-associated infection (HAI) prevention programs. In addition, HAIs are increasingly included in public reporting and payment mandates. Conventional manual surveillance methods are resource intensive and lack standardization. Developments in information technology have propelled a movement toward the use of standardized and semiautomated methods.When developing automated surveillance systems, several strategies can be chosen with regard to the degree of automation and standardization and the definitions used...
