Tailoring surface morphology on anatase TiO supported Au nanoclusters: implications for O activation.

Strong interaction between the support surface and metal clusters activates the adsorbed molecules at the metal cluster-support interface. Using plane-wave DFT calculations, we precisely model the interface between anatase TiO and small Au nanoclusters. Our study focusses on the adsorption and activation of oxygen molecules on anatase TiO, considering the influence of oxygen vacancies and steps on the surface.

Monteggia Fracture in an Extremely Preterm Infant with Biochemical Rickets: A Case Report.

Case: A preterm neonate with biochemical rickets is found to have a Monteggia fracture. The infant underwent percutaneous pinning. There was loss of fixation; however, the infant has been followed since discharge from the hospital and has completely healed with full range of motion.

Death in a Carbon Dioxide Therapy Bath: A Case Report and Review of the Literature.

Carbon dioxide (CO) therapy is the subcutaneous or transcutaneous administration of CO for therapeutic purposes. Carbon dioxide therapy is used for localized lipolysis, to treat chronic skin conditions, and is a safe treatment. Full-body CO baths are offered in European spa centers, in which the clients are placed into full body bags infused with CO at an optimal concentration range between 1000 and 1400 mg/L (516 000-722 500 ppm).

Thoracoabdominal Asynchrony Is Not Associated with Oxyhemoglobin Saturation in Recovering Premature Infants.

Background: Recovering premature infants are at risk for hypoxemia and lack of synchrony between their rib cage and abdomen due to airflow obstruction and poor respiratory compliance. Thoracoabdominal asynchrony (TAA) is a useful marker of resistive and elastic lung properties. Whether TAA predicts oxygenation is unknown.

Impact of neonatal intensive care bed configuration on rates of late-onset bacterial sepsis and methicillin-resistant Staphylococcus aureus colonization.

Background: Infections cause morbidity and mortality in neonatal intensive care units (NICUs). The association between nursery design and nosocomial infections is unclear.

Objective: To determine whether rates of colonization by methicillin-resistant Staphylococcus aureus (MRSA), late-onset sepsis, and mortality are reduced in single-patient rooms.

Sepsis from the gut: the enteric habitat of bacteria that cause late-onset neonatal bloodstream infections.

Background: Late-onset sepsis is a major problem in neonatology, but the habitat of the pathogens before bloodstream invasion occurs is not well established.

Methods: We examined prospectively collected stools from premature infants with sepsis to find pathogens that subsequently invaded their bloodstreams, and sought the same organisms in stools of infants without sepsis. Culture-based techniques were used to isolate stool bacteria that provisionally matched the bloodstream organisms, which were then genome sequenced to confirm or refute commonality.
