BACKGROUND: IUI with or without ovarian stimulation (OS) has become a first-line treatment option for many infertile couples, worldwide. The appropriate treatment modality for couples and their clinical management through IUI or IUI/OS cycles must consider maternal and perinatal outcomes, most notably the clinical complication of higher-order multiple pregnancies associated with IUI-OS. With a current global emphasis to continue to decrease maternal and perinatal mortality and morbidity, the World Health Organization (WHO) had established a multi-year project to review the evidence for the establishment of normative guidance for the implementation of IUI as a treatment to address fertility problems, and to consider its cost-effectiveness for lower resource settings...

Amphotericin B (Amp) has been well-successfully used to treat against Leishmania infection, although high toxicity has been found in patients. In the present study, Amp was administered in Leishmania infantum-infected BALB/c mice by three distinct delivery systems aiming to compare their efficacy against challenge infection, as well as their side effects in a murine visceral leishmaniasis (VL) model. This product was administered in a Poloxamer P407 (Pluronic ® F127)-based polymeric micelle system (Amp/M), in the Ambisome ® formulation (Lip-Amp) or in a free format (free Amp)...

Enterovirus 71 (EV71) and coxsackievirus A16 (CA16) are two major etiologic agents associated with hand, foot, and mouth disease (HFMD) worldwide. Despite that they both belong to the Enterovirus genus of the Picornaviridae family, there are many differences in the infection process of these viruses. However, the underlying mechanisms have not been elucidated. Multiple studies indicated that microRNAs (miRNAs) can play critical roles in the host-pathogen interaction. Our previous study reported that EV71 and CA16 infection leads to differential expression of miRNAs in human bronchial epithelial (16HBE) cells...

The spleen has been one of the least understood major organs for centuries. Its significance is relatively well-known today but it seems that all aspects of its activities are not fully understood. Persian medicine (PM) has special views on the function of spleen; many side effects were reported in PM due to spleen dysfunction. On the other hand nowadays splenectomy as a treatment strategy is recommended for some disorders and increasing risk of infections is considered as the most important long term side effect of that...

Tight regulation of immune responses is not only critical for preventing autoimmune diseases but also for preventing immunopathological damage during infections in which overactive immune responses may be more harmful for the host than the pathogen itself. Regulatory T cells (Tregs) play a critical role in this regulation, which was discovered using the Friend retrovirus (FV) mouse model. Subsequent FV studies revealed basic biological information about Tregs, including their suppressive activity on effector cells as well as the molecular mechanisms of virus-induced Treg expansion...

NK cells play important role in immunity against pathogens and cancer. NK cell functions are regulated by inhibitory and activating receptors binding corresponding ligands on the surface of target cells. NK cells were shown to be recruited to the CNS following several pathological conditions. NK cells could impact CNS physiology by killing glial cells and by secreting IFN-γ. Astrocytes are intimately involved in immunological and inflammatory events occurring in the CNS and reactive astrogliosis is a key feature in HIV-associated neurocognitive disorders...

BACKGROUND: Patients with geriatric hip fractures may be at increased risk for postoperative Clostridium difficile colitis, which can cause severe morbidity and can influence hospital quality metrics. However, to our knowledge, no large database study has calculated the incidence of, factors associated with, and effect of C. difficile colitis on geriatric patients undergoing hip fracture surgery. QUESTIONS/PURPOSES: To use a large national database with in-hospital and postdischarge data (National Surgical Quality Improvement Program [NSQIP®]) to (1) determine the incidence and timing of C...

Urosepsis is defined as a severe disease due to organ failure caused by a urinary tract infection. An empirical antibiotic therapy should be instigated within the first hour after diagnosis. Urine cultures and blood cultures should be performed before antibiotic treatment. Further diagnostics should be carried out at an early stage to enable an interventional focus control in the case of urinary tract obstruction or abscess formation, if necessary. Gram-negative pathogens are most frequently isolated. Extended spectrum beta-lactamase (ESBL) forming bacteria as a cause of urosepsis are increasing...

Enterovirus 71 (EV71) is the primary causative pathogen of hand, foot, and mouth disease (HFMD), affecting children with severe neurological complications. Pyroptosis is a programmed cell death characterized by cell lysis and inflammatory response. Although proinflammatory response has been implicated to play important roles in EV71-caused diseases, the involvement of pyroptosis in the pathogenesis of EV71 is poorly defined. We show that EV71 infection induced caspase-1 activation. Responding to the activation of caspase-1, the expression and secretion of both IL-1β and IL-18 were increased in EV71-infected cells...

T helper (Th) 9 cells play a critical role in immune-mediated diseases, including allergic airway inflammation, autoimmune diseases, and cancer development. Thus, the promotion or suppression of Th9 cell differentiation, transcriptional control, and function is very important for a healthy immune system. Interestingly, T cell maturation, differentiation and function are highly dependent on the individuals' zinc status. This is especially seen in zinc deficient individuals as in the elderly population often suffering of autoimmunity and increased incidence of infections...

An important challenge facing the application of implanted biomaterials for tissue engineering is the need to facilitate desirable tissue interactions with the implant while simultaneously inhibiting bacterial colonization, which can lead to implant-associated infection. In this study, we explore the relevance of physical parameters of polyelectrolyte multilayers, surface charge, wettability and stiffness, in tissue cell/surface and bacteria/surface interactions, and investigate the tuning of the multilayer architecture to differentially control such interactions...

REVIEW
Jaclyn Mallard, Kenneth Williams
Non-human primate models of AIDS and neuroAIDS are critical to study HIV infection of the CNS, neuropathology, and immune activation and macrophage accumulation that occurs in HAND. SIV, similar to HIV, infects CD4+ T lymphocytes and monocytes/macrophages. Virus enters the CNS early, and macrophage activation correlates with CNS disease, as well as inflammation outside of the CNS. Antiretroviral in HIV+ humans and SIV+ Rhesus macaques results in non-detectable plasma virus, decreased or non-detectable viral RNA or protein in the CNS...

OBJECTIVE: For many years, the microsurgical transoral approach (TOA) has been accepted as the "gold standard" for the surgical treatment of a variety of congenital, developmental, and acquired pathologies affecting the craniovertebral junction. In the present study, we try to investigate both experimental and clinical fronts of such a challenging surgery, starting from the updated literature experience. TOA is actually presented as an "old-fashioned" surgical technique dealing with possible bacterial contamination, the need of postoperative nose gastric tube feeding for a week, the possible nasopharyngeal incompetence, and the postoperative tongue swelling...

Enterovirus A71 (EV-A71), coxsackievirus A16 (CV-A16), and CV-A6 are the major causative agents of Hand-foot-and-mouth disease (HFMD). These viruses belong to the species Enterovirus A of the genus Enterovirus of the family Picornaviridae. These viruses can also cause aseptic meningitis (AM), encephalitis and/or paralysis. EV-A71 is one of the main infectious agents related to severe encephalitis. Between 1997 and 2013, East and Southeast Asia experienced large encephalitis outbreaks caused by EV-A71 infections, which ranged from severe to lethal...

BACKGROUND: In Ireland, the setting for this study, the national prevalence rate of health care-associated infection (HCAI) in acute-care facilities is 5.2%. Hand hygiene and in particular hand rubbing using alcohol-based hand rub (ABHR) is highly efficacious in preventing HCAI transmission. Yet, compliance among healthcare professionals is sub-optimal. Less is known about the practices of nursing and medical students and no study comparing practices among these groups in Ireland was found...
