OBJECTIVE: Sepsis is life-threatening organ dysfunction caused by a dysregulated host response to infection. It is the most common cause of death among critically ill patients in non-coronary intensive care units and the incidence continues to rise. Although advanced management was applied, the prognosis of sepsis patients remains poor. As a G-protein coupled receptor, cannabinoid receptor 2 (CB2R) was implicated in a wide variety of diseases. In this study, we aimed to investigate the role of CB2R in sepsis...

Background: Aerococcus urinae has lately been acknowledged as a cause of infective endocarditis (IE) especially in older males with underlying urinary tract disorders. In this population, cardiac implanted electronical devices (CIED) are not uncommon, but despite the capacity of A. urinae to form biofilm in vitro , no cases of aerococcal CIED infections have been reported to date. Case Presentation: An 84-year-old male with pacemaker was admitted with dysuria one month after a transurethral procedure for urinary bladder cancer...

Background: Epstein-Barr virus- (EBV-) associated lymphoproliferative disease (LPD) is a rare condition, usually occurring in immunocompromised patients. We report a case of EBV-associated LPD in a patient with severe celiac disease, the first report to describe this syndrome in a patient with this diagnosis. Case Summary: A 69-year-old Caucasian woman with recent diagnosis of celiac sprue presented to our hospital with persistent diarrhea, abdominal pain, weight loss, and fatigue despite adherence to gluten-free diet for a number of weeks prior to presentation...

REVIEW
Christoph Jans, Annemarie Boleij
The Streptococcus bovis/Streptococcus equinus complex (SBSEC) comprises several species inhabiting the animal and human gastrointestinal tract (GIT). They match the pathobiont description, are potential zoonotic agents and technological organisms in fermented foods. SBSEC members are associated with multiple diseases in humans and animals including ruminal acidosis, infective endocarditis (IE) and colorectal cancer (CRC). Therefore, this review aims to re-evaluate adhesion and colonization abilities of SBSEC members of animal, human and food origin paired with genomic and functional host-microbe interaction data on their road from colonization to infection...

S. aureus associated bacteremia can lead to severe infections with high risk of mortality (e.g. sepsis, infective endocarditis). Many virulence factors and adhesins of S. aureus are known to directly interact with platelets. Extracellular adherence protein, Eap, one of the most important virulence factors in S. aureus mediated infections is a multi-tandem domain protein and has been shown to interact with almost all cell types in the human circulatory system. By using amine reactive fluorescent N-hydroxysuccinimidyl (NHS)-ester dyes and by direct detection with primary fluorescently conjugated anti-histidine (His-tag) antibodies against detect N-terminal His6, we show Eap subdomain Eap D3 D4 specifically interacts and rapidly activates human platelets...

BACKGROUND AND AIMS: Scientific evidence is not clear regarding the use of antimicrobial mouth rinse before dental extraction to reduce bacteremia. We tested the null hypothesis that there would be no difference in the incidence of bacteremia following dental extractions in patients treated with or without chlorhexidine. MATERIAL AND METHODS: We conducted a meta-analysis following the recommendations proposed by PRISMA Preferred Reporting Items for Systematic Reviews and Meta-Analyses...

BACKGROUND: Emerging resistance to antibiotics renders therapy of Typhoid Fever (TF) increasingly challenging. The current single-drug regimens exhibit prolonged fever clearance time (FCT), imposing a great burden on both patients and health systems, and potentially contributing to the development of antibiotic resistance and the chronic carriage of the pathogens. The aim of our study was to assess the efficacy of combining third-generation cephalosporin therapy with azithromycin on the outcomes of TF in patients living in an endemic region...

Systemic levels of cytokines are altered during infection and sepsis. This prospective observational study aimed to investigate whether plasma levels of multiple inflammatory mediators differed between sepsis patients with and those without bacteremia during the initial phase of hospitalization. A total of 80 sepsis patients with proven bacterial infection and no immunosuppression were included in the study. Plasma samples were collected within 24 h of hospitalization, and Luminex® analysis was performed on 35 mediators: 16 cytokines, six growth factors, four adhesion molecules, and nine matrix metalloproteases (MMPs)/tissue inhibitors of metalloproteinases (TIMPs)...

Consumer perception of poor hygiene of fresh milk products is a major barrier to promotion of milk consumption as an intervention to alleviate the burden of malnutrition in Ghana. Fresh milk is retailed raw, boiled, or processed into unfermented cheese and spontaneously fermented products in unlicensed outlets. In this study, we have determined microbiological quality of informally retailed fresh milk products and characterized the genomic diversity and antimicrobial resistance (AMR) patterns of non-typhoidal Salmonella (NTS) in implicated products...

Infection of the driveline or pump pocket is a common complication in patients with ventricular assist devices (VADs) and Staphylococcus aureus is the main pathogen causing such infections. Limited evidence is currently available to guide the choice of antibiotic therapy and the duration of treatment in these patients. Patients at the University Medical Center Utrecht who developed a VAD-related S. aureus infection between 2007 and 2016 were retrospectively assessed. Blood culture isolates were typed by whole genome sequencing to differentiate between relapses and reinfections, and to determine whether antibiotic therapy had led to acquisition of resistance mutations...

Tzu-Ting Chen, Yi-Chun Yeh, Kuo-Liong Chien, Mei-Shu Lai, Yu-Kang Tu
Background -Invasive dental treatments (IDTs) can yield temporary bacteremia and has therefore been considered a potential risk factor of infective endocarditis (IE). It is hypothesized that, through the trauma caused by IDTs, bacteria gain entry to the bloodstream and may attach to abnormal heart valves or damaged heart tissue, giving rise to IE. However, the association between IDTs and IE remains controversial. The aim of this study is to estimate the association between IDTs and IE. Methods -The data in this study were obtained from the Health Insurance Database in Taiwan...

PURPOSE: Stenotrophomonas maltophilia has low pathogenicity potential, but if it causes bacteremia it can be fatal, because it has shown high resistance to many antibiotics and can be difficult to treat. Patient death from S. maltophilia bacteremia has increased since 2014 in our hospital. In this study, we investigated risk factors for death due to S. maltophilia bacteremia. METHODS: Seventy patients from the hospital database with S. maltophilia bacteremia between January 2010 and July 2017 were investigated...

Reducing graft thickness is essential to prevent large-for-size graft problems in pediatric living donor liver transplantation (LDLT). However, long-term outcomes of LDLT using reduced-thickness left lateral segment (LLS) grafts are unclear. In 89 patients who underwent LDLT using reduced LLS grafts between 2005 and 2017, short-term and long-term outcomes were compared between a non-anatomically reduced LLS (NAR-LLS) graft group and a reduced-thickness LLS graft group. Estimated blood loss was lower and abdominal skin closure was less needed in the recipient operation in the reduced-thickness LLS graft group...

PURPOSE: Respiratory complications are the leading causes of morbidity and mortality after lung cancer surgery. We hypothesized that oropharyngeal and nasopharyngeal decontamination with chlorhexidine gluconate (CHG) would be an effective method to reduce these complications as reported in cardiac surgery. METHODS: In this multicenter parallel-group randomized double-blind placebo-controlled trial, we enrolled consecutive adults scheduled for anatomical pulmonary resection for lung cancer...

Francisella tularensis is a highly infectious Gram-negative bacterium that is the etiologic agent of tularemia in animals and humans and a Tier 1 select agent. The natural incidence of pneumonic tularemia worldwide is very low; therefore, it is not feasible to conduct clinical efficacy testing of tularemia medical countermeasures (MCM) in human populations. Development and licensure of tularemia therapeutics and vaccines need to occur under the Food and Drug Administration's (FDA's) Animal Rule under which efficacy studies are conducted in well-characterized animal models that reflect the pathophysiology of human disease...

Staphylococcus aureus infective endocarditis (SaIE) is a severe complication of S. aureus bacteremia (SAB) occurring in up to 22% of patients. Bacterial genetic factors and host conditions for SaIE have been intensely studied before; however, to date no study has focused on predisposing host genetic factors to SaIE. The present study aimed to identify genetic polymorphisms associated with SaIE by a Genome-Wide Association Study (GWAS) of 67 patients with definite native valve SaIE (cases) and 72 matched native valve patients with SAB but without IE (controls)...

BACKGROUND: Cytomegalovirus (CMV) is the most common viral infection in liver transplant recipients that influences the outcomes of liver transplantation. However, its impact on early outcomes following living donor liver transplantation (LDLT) is not fully defined in the Indian subcontinent. This study was done to assess the impact of CMV infection on early post-transplant outcomes in LDLT recipients. METHODS: Out of 272 LDLTs performed from January 2012 to April 2013, 151 recipients underwent CMV viral load analysis in plasma within 90 days post LDLT based on clinical suspicion...

Participants' understanding of key elements of a research protocol is essential to their ethical enrollment in the study. Ongoing participation should be based on continued comprehension and consent, which presumes a high degree of recall. Many obstacles can prevent full understanding of information about the research protocol. This study's aim was to evaluate the comprehension and 1-day recall of the elements of informed consent by the parents/guardians of children enrolled in a clinical study in Mozambique...
