Blood stream infections (BSI) caused by enteric organisms are associated with a particularly high mortality rate in allogeneic hematopoietic cell transplantation (AlloHCT) recipients. We conducted a retrospective multicenter study aiming to analyze the risk factors associated with antibiotic resistance and impact of BSI on transplant related mortality (TRM) in children following alloHCT. During the study period from 2004 to 2014, 395 children (mean age 9.4 years) with at least one BSI were included. The incidences of resistant gram-negative rods (GNR) were 20...

BACKGROUND: Patients with intestinal failure (IF) are candidates for intestinal transplantation (ITx). In Japan, these patients have few opportunities to undergo cadaveric ITx because of low rates of organ donation. The donor criteria and recipient priority for ITx are still unknown. We reviewed our cases of IF to investigate which patients should be prioritized for ITx. METHODS: Patients with IF who were registered as candidates for cadaveric ITx between January 2010 and November 2015 in our institute were included in this retrospective study...

Hospital admissions related to burn injury reach 40,000 annually. Patients who experience extensive burns require longer hospital stays and are at increased risk for infection and hospital acquired conditions. This comparative case study is a two patient matched case control design that follows the hospital course of two children who experienced burn injuries. For one of these patients, with the consent of the child's parents, the grandmother treated her granddaughter with essential oils. Essential oils have the potential to inhibit microbial growth, support treatment of wounds, and facilitate healing...

OBJECTIVE: Our objective was to safely reduce the number of peripherally inserted central catheters (PICCs) inserted in infants with umbilical venous catheter using quality improvement methods. STUDY DESIGN: In a tertiary neonatal intensive care unit, a questionnaire designed to prompt critical thinking around the decision to place a PICC, along with an updated standardized feeding guideline was introduced. PICC insertion in 86 infants with umbilical venous catheter (pre intervention) with birth weight 1000-1500 g were compared with 115 infants (post intervention) using Fisher's exact test...

Introduction Ethanol lock solution has been mainly administered in paediatric and home parenteral nutrition patients in order to prevent catheter related blood stream infections (CRBSI). Its utility in hemodialysis (HD) patients with non-tunneled-uncuffed catheter (NTC) has been poorly explored. Methods We conducted a prospective randomized study in chronic HD patients requiring a newly inserted NTC-while awaiting for the maturation of an already established arteriovenous fistula (AVF) or arteriovenous graft (AVG) or tunneled-cuffed catheter insertion...

Many pulmonary infections elicit lymphocyte responses that lead to an accumulation of granulocytes in the lungs. A variety of lymphocytes are capable of directing eosinophils or neutrophils to the lungs, but the contribution of each subset remains enigmatic. In this study, we used a murine model to examine lymphocyte subsets that ultimately drive the eosinophil or neutrophil response to infection with the fungal pathogen Cryptococcus neoformans. We show that granulocytes are produced in the bone marrow, released into the blood stream, and accumulate in the lungs under the instruction of lung parenchymal lymphocytes...

BACKGROUND: Patients with multiple myeloma are generally immune-compromised either due to pronounced depression in primary antibody responses or because of anti-myeloma therapy. Infection is a major risk factor for early deaths among these patients. The impact of blood stream infections (BSI) on newly diagnosed myeloma patients has been less studied. We aimed to study the incidence and risk factors of BSI within 3 months after diagnosis of multiple myeloma in a tertiary referral center...

OBJECTIVE: To describe the nutritional provisions received by infants with surgical NEC and the associated effects on short-term growth. STUDY DESIGN: Through the Children's Hospitals Neonatal Database we identified infants born ≤32 weeks' gestation with surgical NEC from 5 regional neonatal intensive care units over 4 years. Excluded infants had isolated intestinal perforation and died <14 days post-operatively. Infants were stratified by their median parenteral protein dose (low (LP) or high (HP) protein) over the first post-operative week...

Bacterial blood stream infection (BSI) potentially leads to life-threatening clinical conditions and medical emergencies such as severe sepsis, septic shock, and multi organ failure syndrome. Blood culturing is currently the gold standard for the identification of microorganisms and, although it has been automated over the decade, the process still requires 24-72 h to complete. This long turnaround time, especially for the identification of antimicrobial resistance, is driving the development of rapid molecular diagnostic methods...

Semi-permanent dual-lumen tunneled (or tunneled-cuffed) hemodialysis catheters (TDC) are increasingly utilized during renal replacement therapy, while awaiting permanent access maturation or renal recovery. Although there is a wealth of literature focused on placement, infection prevention, and maintenance of catheter patency, circumstances and indications for TDC removal are less well understood. Timely removal of these catheters is an important management decision, with the length of TDC duration representing the largest cumulative risk factor for catheter-associated blood stream infections...

There has been controversy about the intrinsic virulence of methicillin-resistant Staphylococcus aureus (MRSA) as compared to methicillin-susceptible S. aureus (MSSA). To address this discrepancy, the intrinsic virulence of 42 MRSA and 40 MSSA clinical isolates was assessed by testing endothelial cell (EC) damage, a surrogate marker for virulence in blood stream infections. Since these clinical isolates represent a heterogeneous group, well characterized S. aureus laboratory strains with SCCmec loss- and gain-of-function mutations were used in addition...

Neonatal meningitis is a lethal infection occurring in the 1st month of life. The risk of developing permanent neurological sequels is high among the neonates who survive. Bacterial pathogens are commonly associated with this condition. Aeromonas is a Gram-negative bacteria of aquatic habitat. Although isolation of Aeromonas species from neonates with blood stream infection is infrequently reported, neonatal meningitis caused by Aeromonas is exceedingly rare. We present a case of fulminant sepsis and meningitis caused by Aeromonas hydrophila in a preterm newborn male...

INTRODUCTION: Recent years have seen a rise of coagulase-negative staphylococci (CoNS) from common contaminants to agents of nosocomial blood stream infections (BSI's). Molecular typing and establishing a correlation with antibiotic resistance is essential particularly in countries like India where genotyping studies for drug-resistant CoNS are sparse. METHODS: A prospective study was done over 18 months, wherein 42,693 blood samples were received, and 59 patients with BSI due to CoNS were evaluated...

Decreased ciprofloxacin susceptibility (DCS) and multidrug resistance in typhoidal Salmonella isolates in areas of endemicity are significant therapeutic problems. Guidelines for azithromycin disc diffusion and MIC interpretive criteria for Salmonella enterica serovar Typhi were published recently by the Clinical and Laboratory Standards Institute in 2015. We investigated the antimicrobial susceptibility pattern of azithromycin in 100 isolates of Salmonella Typhi (n=80), Paratyphi A (n=18) and B (n=2) recovered from bloodstream infections from January 2013 to December 2015...

CD4(+) T cell repopulation of the gut is rarely achieved in HIV-1-infected individuals who are receiving clinically effective antiretroviral therapy. Alterations in the integrity of the mucosal barrier have been indicated as a cause for chronic immune activation and disease progression. In this study, we present evidence that persistent immune activation causes impairment of lymphocytes to respond to chemotactic stimuli, thus preventing their trafficking from the blood stream to peripheral organs. CCR6(+) and CXCR3(+) Th cells accumulate in the blood of aviremic HIV-1-infected patients on long-term antiretroviral therapy, and their frequency in the circulation positively correlates to levels of soluble CD14 in plasma, a marker of chronic immune activation...
