RESUMO
OBJECTIVES: The goal of this systematic review was to determine whether antimicrobial lock (AML) solutions prevent catheter-related bloodstream infections (CRBSI) in children with intestinal failure (IF). METHODS: Electronic databases were searched: Ovid MEDLINE (1946-), Ovid Embase (1974-), Wiley Cochrane Library (inception-), and Web of Science Core Collection via Clarivate Analytics (1900-). Randomized and nonrandomized trials, case or cohort studies that studied any AML solution, and used comparator groups were included if they studied children with IF. A meta-analysis compared the rates of CRBSI with AML solutions versus controls, and a Boucher analysis was used to indirectly compare AML solutions. RESULTS: Twenty-eight studies met eligibility criteria (1 open label and 27 observational studies). Quality was good (N = 13), fair (N = 9), and poor (N = 6). All but 4 studied ethanol and taurolidine. Of 15 ethanol studies, 11 reported a decrease and 3 reported a trend toward a decreased incidence of CRBSI compared to controls; 1 reported no difference. Of 9 taurolidine studies, 7 reported a decrease and 2 a trend toward decreased CRBSI rates. There was a decrease in CRBSI with ethanol versus control ( P = 0.008) and with taurolidine-citrate versus control ( P < 0.0005). Using Bucher indirect comparison of the pooled estimates from ethanol versus control to taurolidine versus control, the estimated difference was -0.99 (-4.125, 2.27; P = 0.55). CONCLUSIONS: There were no randomized trials and over half of the 28 included studies were fair or poor quality. All but 1 reported at least a trend toward reduction in CRBSI. AML solutions appear to prevent CRBSI.

In this study we used event-related brain potentials (ERP) as neural markers of cognitive operations to examine emotion and attentional processing in a population of high-risk adolescents with mental health problems that included attention deficit and hyperactivity disorder (ADHD), anxiety, and depression. We included a healthy control group for comparison purposes, and employed a modified version of the emotional oddball paradigm, consisting of frequent distracters (scrambled pictures), infrequent distracters (sad, fearful, and neutral pictures), and infrequent targets (circles). Participants were instructed to make a right hand button press to targets and a left hand button press to all other stimuli. EEG/ERP recordings were taken using a high-density 256-channel recording system. Behavioral data showed that for both clinical and non-clinical adolescents, reaction time (RT) was slowest in response to the fearful images. Electrophysiological data differentiated emotion and target processing between clinical and non-clinical adolescents. In the clinical group we observed a larger P100 and late positive potential (LPP) in response to fearful compared to sad or neutral pictures. There were no differences in these ERPs in the healthy sample. Emotional modulation of target processing was also identified in the clinical sample, where we observed an increase in P300 amplitude, and a larger sustained LPP in response to targets that followed emotional pictures (fear and sad) compared to targets that followed neutral pictures or other targets. There were no differences in these target ERPs for the healthy participants. Taken together, we suggest that these data provide important and novel evidence of affective and attention dysfunction in this clinical population of adolescents, and offer an example of the disruptive effects of emotional reactivity on basic cognition.
