Orf virus has been utilized as a safe and efficient viral vector against not only diverse infectious diseases, but also against tumors. However, the nature of the genes triggered by the vector in human cells is poorly characterized. Using RNA sequencing technology, we compared specific changes in the transcriptomic profiles in human foreskin fibroblast cells following infection by the orf virus. The results indicated that orf virus upregulates or downregulates expression of a variety of genes, including genes involved in antiviral immune response, apoptosis, cell cycle and a series of signaling pathways, such as the IFN and p53-signaling pathways...

Significant sex differences exist in the activity of the hypothalamic-pituitary-adrenal (HPA) axis. These differences are thought to contribute to the disparity in the prevalence of various autoimmune and infectious diseases between males and females. We use a mathematical model of the HPA axis to evaluate the hypothesis that differential sensitivity and negative feedback of the HPA axis network are causal factors for the observed sex differences in its activity. In doing so, we implicitly account for the differential influence of gonadal hormones on the HPA axis...

Research documents significant gender-based salary inequities among physicians and ongoing inadequacies in recruitment and promotion of physicians from underrepresented minority groups. Given the complexity of the social forces that promote these disparities, their elimination will likely require quantitative and qualitative research to understand the pathways that lead to them and to develop effective solutions. Interventions to combat implicit bias will be required, and structural interventions that hold medical school leadership accountable are needed to achieve and maintain salary equity and racial and gender diversity at all levels...

While a career in infectious diseases (ID) has always been challenging and exciting, recognition of the value that ID physicians provide to the healthcare system as a whole, over and above the value they provide to individual patients, has been poor in this system. In response to this disparity, the Infectious Diseases Society of America Clinical Affairs Committee has long endeavored to quantify the value of ID physicians to the system, which is challenging in part because of the many avenues through which they influence healthcare...

The decline in applications for infectious diseases (ID) fellowships has been an area of active introspection for the leadership of the Infectious Disease Society of America (IDSA). This prompted actions to address the problem, including surveys of current and former fellows. Ironically, the decline in applications to ID programs is occurring at a time when the need for ID providers has never been greater and the excitement and variety in the practice of ID has never been higher. Data regarding the current ID workforce are presented here, along with perspectives about the future of the profession in the decades to come...

Public health offers infectious disease physicians a variety of rewarding career options. Our training and skills make us well suited to a variety of roles in public health. This article summarizes some of the options for careers in public health and describes why ID physicians are so well suited to them.

Paracoccidioidomycosis (PCM) is an infectious disease endemic to South America, caused by the thermally dimorphic fungi Paracoccidioides. Currently, there is no effective human vaccine that can be used in prophylactic or therapeutic regimes. We tested the hypothesis that the immunogenicity of the immunodominant CD4+ T-cell epitope (P10) of Paracoccidioides brasiliensis gp43 antigen might be significantly enhanced by using a hepatitis B virus-derived particle (VLP) as an antigen carrier. This chimera was administered to mice as a (His)6-purified protein (rPbT) or a replication-deficient human type 5 adenoviral vector (rAdPbT) in an immunoprophylaxis assay...

Foot-and-mouth disease virus (FMDV) belongs to the aphthovirus genus of the Picornaviridae, a family of small, icosahedral, non-enveloped, single-stranded RNA viruses. It is a highly infectious pathogen and is one of the biggest hindrances to the international trade of animals and animal products. FMDV capsids (which are unstable below pH6.5) release their genome into the host cell from an acidic compartment, such as that of an endosome, and in the process dissociate into pentamers. Whilst other members of the family (enteroviruses) have been visualized to form an expanded intermediate capsid with holes from which inner capsid proteins (VP4), N-termini (VP1) and RNA can be released, there has been no visualization of any such state for an aphthovirus, instead the capsid appears to simply dissociate into pentamers...

Many emerging viruses such as Ebola and Lassa occur in resource-limited areas of the world. The advent of multiplex immunoassays has facilitated the study of biomarkers of disease since only small amounts of clinical material are required; however, such assays are designed and validated for only plasma or serum. This is a significant impediment when studying infectious diseases in the context of an outbreak in a developing nation. Plasma or serum can be difficult to obtain in the field due to the need for additional processing of infectious materials...

Globally, 32.4 million individuals are blind and 191 million have moderate or severe visual impairment (MSVI); 80% of cases of blindness and MSVI are avoidable. However, great efforts are needed to tackle blindness and MSVI, as eye care in most places is delivered in isolation from and without significant integration with general health sectors. Success stories, including control of vitamin A deficiency, onchocerciasis, and trachoma, showed that global partnerships, multisectoral collaboration, public-private partnerships, corporate philanthropy, support from nongovernmental organizations-both local and international-and governments are responsible for the success of these programs...

Isolated infectious endocarditis of the pulmonary valve is a rare condition and represents 1,5-2% of all cases of infectious endocarditis. We present a case of a 37year-old woman without any relevant medical history. The woman was hospitalized with hallmarks of severe sepsis and bilateral pneumonia; she died several hours after admission with progressive multiorgan failure and disseminated intravascular coagulopathy. Microbiologic examination approved Staphylococcus aureus as the etiological agent. The autopsy showed isolated endocarditis of the pulmonary valve, without any known predisposing factor...

Infectious diseases are resulted from the invasion of an organism's body tissues by multiple disease-causing agents. It has been demonstrated that the occurrence and development of infectious diseases are closely associated with the functional status of immune system. Cytokines play significant roles in modulating the host immune response to the clearance of pathogenic microorganisms and maintaining immune homeostasis. Interleukin-35 (IL-35), as a newly identified member of IL-12 family, exerts suppressive effect on immune response by means of a specific pattern...

Hospital acquired pneumonia (HAP) and ventilatorassociated pneumonia (VAP) are common hospital-acquired infections with higher mortality, longer hospital stay and more hospitalization expenses. With the latest research results and evidence-based guideline methodology, Infectious Diseases Society of America (IDSA) and American Thoracic Society (ATS) have collaborated to create updated guidelines for the diagnosis and treatment of HAP and VAP in 2016. It is worth critically reading and thinking that most recommendations are supported by low-quality or very-low quality evidence and some strong recommendations is different from the actual clinical work in China...

Exosomes are extracellular vesicles of 50-150 nm in diameter secreted by basically all cell types. They mediate micro-communication among cells, tissues, and organs under both healthy and disease conditions by virtue of their ability to deliver macromolecules to target cells. Research on exosomes is a rapidly growing field, however many aspects of their biogenesis and functions still await a complete clarification. In our review we summarize most recent findings regarding biogenesis, structure, and functions of exosomes...
