Infections (including sepsis, meningitis, pneumonia and tetanus) stand as a major contributor to neonatal mortality in Haiti (22%). Infants acquire bacteria that cause neonatal sepsis directly from the mother's blood, skin or vaginal tract either before or during delivery. Nosocomial and environmental pathogens introduce further risk after delivery. The absence of cohesive medical systems and methods for collecting information limits the available data in countries such as Haiti. This study seeks to add more information on the burden of severe bacterial infections and their etiology in neonates of Haiti...

We report a case of a 77-year old male who developed a fulminant erysipelas and sepsis, caused by Myroides odoratimimus. Selecting the optimal antibiotic therapy for the treatment of infections with M. odoratimimus is challenging due to limited clinical experience with this micro-organism and its reported multidrug-resistance. Review of previous studies concerning in vitro antibacterial susceptibility and clinical experience with M. odoratimimus resulted in six case reports describing bacteremia, soft tissue and bone infections, pneumonia and urinary tract infections...

BACKGROUND: Ventilator-associated pneumonia (VAP) is a significant cause of morbidity and mortality, complicating the medical course of approximately 10% of mechanically-ventilated patients, with an estimated attributable mortality of 13%. To treat VAP empirically, the American Thoracic Society currently recommends antibiotic therapy based on the patients' risk of colonisation by an organism with multidrug resistance. The selection of initial antibiotic therapy in VAP is important, as inappropriate initial antimicrobial treatment is associated with higher mortality and longer hospital stay in intensive care unit (ICU) patients...

Porcine enzootic pneumonia (EP) caused by Mycoplasma hyopneumoniae adversely affects pig welfare and is associated with major economic losses in the pig industry worldwide. Transmission is predominantly by direct contact but the role of indirect transmission remains poorly understood. This study examined survival of six M. hyopneumoniae isolates dried onto five different surfaces encountered in pig units, and exposed to temperatures of 4°C, 25°C and 37°C for up to 12 days. Survival of the organisms was determined by recovering the organism from the surface material and culturing in Friis broth...

The treatment of complicated intra-abdominal infections (cIAI) is increasingly challenging due to increased resistance of Gram-negative organisms. These multidrug resistant organisms lead to an increase in morbidity and mortality. This has led to renewed interest in use of older β-lactam antibiotics in combination with newer β-lactamase inhibitors. Ceftazidime-avibactam is one of the newest such combination antibiotics, which has been released for treatment of complicated intra-abdominal infections in combination with metronidazole...

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: To identify associations between abnormal coagulation profile and postoperative morbidity and mortality in patients undergoing posterior lumbar fusion (PLF). SUMMARY OF BACKGROUND DATA: The literature suggests that abnormal coagulation profile is associated with postoperative complications, notably the need for blood transfusion. However, there is little research that directly addresses the influence of coagulation profile on postoperative complications following PLF...

BACKGROUND: Each year in China, approximately 700,000 children under 5 years old are diagnosed with pneumonia, and 30,000 die of the disease. Although 7-valent pneumococcal conjugate vaccine (PCV-7) and 23-valent pneumococcal polysaccharide vaccine (PPV-23) are available in China, the costs are borne by the consumer, resulting in low coverage for PCV-7. We aimed to conduct a simulation study to assess the cost-effectiveness and health benefits of PCV-7, 13-valent pneumococcal conjugate vaccine (PCV-13) and PPV-23 to prevent childhood pneumonia and other vaccine-preventive diseases in China...

OBJECTIVE: Adverse cardiovascular events (ACVEs) account for a large proportion of the morbidities and mortalities associated with drug overdose emergencies. However, there are no published reports regarding outcomes of ACVEs associated with acute dapsone poisoning. Here, the authors retrospectively analyzed ACVEs reported within 48 hours of treatment in patients with acute dapsone poisoning and assessed the significance of ACVEs as early predictors of mortality. METHODS: Sixty-one consecutive cases of acute dapsone poisoning that were diagnosed and treated at a regional emergency center between 2006 and 2014 were included in the study...

Disposable bronchoscopes such as the Ambu aScope(TM) 3 are marketed as 'single use' The risks of contamination from prolonged device storage before possible re-use are unknown. Following clinical bronchoscopy in patients whose lungs were mechanically ventilated, 20 aScope(TM) 3's bronchoscopes received a standard 'social clean' and were then stored. Subsequent paired saline flush and swab samples were taken at time zero, and at 24 h and 48 h. Positive microbiological cultures were obtained from at least one time point from 16 of the 20 bronchoscopes...

Global regulators play an essential role in the adaptation of bacterial cells to specific niches. Bacterial pathogens thriving in the tissues and organs of their eukaryotic hosts are a well-studied example. Some of the proteins that recognize local DNA structures rather than specific nucleotide sequences act as global modulators in many bacteria, both Gram-negative and -positive. To this class of regulators belong the H-NS-like proteins, mainly identified in γ-Proteobacteria, and the MgaSpn-like proteins identified in Firmicutes...

BACKGROUND & AIMS: Recent clinical trials and in vivo models demonstrate probiotic administration can reduce occurrence and improve outcome of pneumonia and sepsis, both major clinical challenges worldwide. Potential probiotic benefits include maintenance of gut epithelial barrier homeostasis and prevention of downstream organ dysfunction due to systemic inflammation. However, mechanism(s) of probiotic-mediated protection against pneumonia remain poorly understood. This study evaluated potential mechanistic targets in the maintenance of gut barrier homeostasis following Lactobacillus rhamnosus GG (LGG) treatment in a mouse model of pneumonia...

To identify the pathogenic micro-organisms that had colonised preoperatively in clefts in the soft palate and oro-nasopharynx, we retrospectively studied the preoperative microbiological profiles of 200 infants who had had primary repair of all types of cleft in the soft palate. Data from a private practice that specialises in the repair of facial clefts were extracted randomly from patients' files. We analysed the results of the culture of preoperative swabs taken from clefts in the soft palate and oro-nasopharynx, and the resistance profile of organisms towards various antibiotics...
