Abstract
When people of any age, despite all possible support being provided, are unable to make a necessary decision, then it is important to have a legal framework which promotes and protects their rights. There is ongoing debate about how this can be achieved, in a non-discriminatory way, for adults but it is also an important consideration for children and young people. In Northern Ireland, the Mental Capacity Act (Northern Ireland) 2016, when fully implemented will provide a non-discriminatory framework for those aged 16 and over. Arguably this addresses discrimination based on disability but continues to discriminate based on age. This article explores some of the possible ways the rights of those aged under 16 could be further promoted and protected. These approaches may include: retaining the current combination of statute law but developing new guidance to inform practice for those aged under 16; codifying Gillick to clarify under what circumstances those aged under 16 can accept, and possibly also refuse, interventions; amend the Children (Northern Ireland) Order 1995 to provide a more comprehensive framework for health and welfare decision making; amend and extend the Mental Capacity Act (Northern Ireland) 2016 to apply to those aged under 16; or develop a new law specifically focused on the emerging capacity of those aged under 16. There are complex issues involved including how to consider emerging or developmental decision-making ability, and the role of those with parental responsibility, but the complexities involved should not prevent these issues being addressed.

Abstract
The increasing prevalence of allergic diseases has placed a significant burden on global healthcare and society as whole. This has necessitated a rapid development of "allergy" as a specialist area. However, as allergy is so common and, for most, relatively easy to diagnose and control, all clinicians need to have basic knowledge and competence to manage mild disease and recognize when referral is required. The allergology specialty has not yet been recognized in many countries and even where allergy is fully recognized as a specialty, the approach to training in allergy differs significantly. In the light of recent developments in allergy diagnosis and management, there is an urgent need to harmonize core competences for physicians, as well as the standardization of core principles for medical education and post-graduate training in allergy. All physicians and allied health professionals must appreciate the multidisciplinary team (MDT) approach to allergy, which is key to achieving the highest standards in holistic care. Due to worldwide variation in resources and personnel, some MDT roles will need to be absorbed by the treating physician or other healthcare professionals. We draw particular attention to the role of psychological input for all allergy patients, dietetic input in the case of food allergy and patient education to support all patients in the supported self-management of their condition on a daily basis. A strong appreciation of these multidisciplinary aspects will help physicians provide quality patient-centered care. We consider that harmonization of allergy components within undergraduate curricula is crucial to ensure all physicians develop the appropriate allergy-related knowledge and skills, particularly in light of inconsistencies seen in the primary care management of allergy. This review from the World Allergy Organization (WAO) Education and Training Committee also outlines allergy-related competences required of physicians working with allergic patients and provides recommendations to promote harmonization of allergy training and practice worldwide.

Abstract
There is a wide time gap between the publication of evidence and the application of new knowledge into routine clinical practice. The consequence is sub-optimal outcomes, particularly concerning for long-term relapsing/remitting conditions such as allergic diseases. In response, there has been a proliferation of published guidelines which systematically review evidence for the gold-standard management of most allergic disorders. However, this has not necessarily been followed by improved outcomes, partly due to a lack of coordination across the patient pathway. This has become known as the "second translational gap". A proposed solution is the development and implementation of integrated care pathways (ICPs) to optimize patient outcomes, with the notion that evidence-based medicine requires evidence-based implementation. ICP implementation is shown to improve short-term outcomes for acute conditions and routine surgery, including reduced length of hospital stay, improved documentation and improved patient safety. However, this improvement is not reflected in patient experience or patient-centered functional outcomes. The implementation of life-long, cost-effective interventions within comprehensive pathways requires a deep appreciation for complexity within allergy care. We promote an evidence-based methodology for the implementation of ICPs for allergic disorders in which all stakeholders in allergy care are positioned equally and encouraged to contribute, particularly patients and their caregivers. This evidence-based process commences with scoping the unmet needs, followed by stakeholder mapping. All stakeholders are invited to meetings to develop a common vision and mission through the generation of action/effect diagrams which helps build concordance across the agencies. Dividing the interventions into achievable steps and reviewing with plan/do/study/act cycles will gradually modify the pathway to achieve the best outcomes. While the management guidelines provide the core knowledge, the key component of implementation involves education, training, and support of all healthcare professionals (HCPs), patients and their caregivers. The pathways should define the level of competence required for each clinical task. It may be useful to leave the setting of care delivery or the specific HCP involved undefined to account for variable patterns of health service delivery as well as local socioeconomic, ethnic, environmental, and political imperatives. In all cases, where competence is exceeded, it is necessary to refer to the next stage in the pathway. The success and sustainability of ICPs would ideally be judged by patient experience, health outcomes, and health economics. We provide examples of successful programs, most notably from Finland, but recommend that further research is required in diverse settings to optimize outcomes worldwide.

Abstract
A large number of biologically active components have been found in human milk (HM), and in both human and animal models, studies have provided some evidence suggesting that HM composition can be altered by maternal exposures, subsequently influencing health outcomes for the breastfed child. Evidence varies from the research studies on whether breastfeeding protects the offspring from noncommunicable diseases, including those associated with immunological dysfunction. It has been hypothesized that the conflicting evidence results from HM composition variations, which contain many immune active molecules, oligosaccharides, lactoferrin, and lysozyme in differing concentrations, along with a diverse microbiome. Determining the components that influence infant health outcomes in terms of both short- and long-term sequelae is complicated by a lack of understanding of the environmental factors that modify HM constituents and thereby offspring outcomes. Variations in HM immune and microbial composition (and the differing infantile responses) may in part explain the controversies that are evidenced in studies that aim to evaluate the prevalence of allergy by prolonged and exclusive breastfeeding. HM is a "mixture" of immune active factors, oligosaccharides, and microbes, which all may influence early immunological outcomes. This comprehensive review provides an in-depth overview of existing evidence on the studied relationships between maternal exposures, HM composition, vaccine responses, and immunological outcomes.

Abstract
Background Previous work has shown patients commonly misuse adrenaline autoinjectors (AAI). It is unclear whether this is due to inadequate training, or poor device design. We undertook a prospective randomized controlled trial to evaluate ability to administer adrenaline using different AAI devices. Methods We allocated mothers of food‐allergic children prescribed an AAI for the first time to Anapen or EpiPen using a computer‐generated randomization list, with optimal training according to manufacturer's instructions. After one year, participants were randomly allocated a new device (EpiPen, Anapen, new EpiPen, JEXT or Auvi‐Q), without device‐specific training. We assessed ability to deliver adrenaline using their AAI in a simulated anaphylaxis scenario six weeks and one year after initial training, and following device switch. Primary outcome was successful adrenaline administration at six weeks, assessed by an independent expert. Secondary outcomes were success at one year, success after switching device, and adverse events. Results We randomized 158 participants. At six weeks, 30 of 71 (42%) participants allocated to Anapen and 31 of 73 (43%) participants allocated to EpiPen were successful – RR 1.00 (95% CI 0.68–1.46). Success rates at one year were also similar, but digital injection was more common at one year with EpiPen (8/59, 14%) than Anapen (0/51, 0%, P = 0.007). When switched to a new device without specific training, success rates were higher with Auvi‐Q (26/28, 93%) than other devices (39/80, 49%; P < 0.001). Conclusions AAI device design is a major determinant of successful adrenaline administration. Success rates were low with several devices, but were high using the audio‐prompt device Auvi‐Q.

Abstract
Temperature-controlled laminar airflow improves symptoms in atopic asthmatics, but its effects on personal allergen exposure are unknown. We aimed to evaluate its effects on personal cat allergen and particulate exposures in a simulated bedroom environment. Five healthy volunteers lay under an active and an inactive temperature-controlled laminar airflow device for 175 min, in a simulated bedroom containing bedding from a cat owner. Total airborne particles (≥0.5 - ≥10 μm diameter) were quantified with a laser particle counter. Airborne allergen was sampled with Institute of Occupational Medicine filters. Inhaled exposure was sampled with nasal air samplers. Allergen-containing particles were quantified by immunoassay. Treatment reduced total airborne particles (>0.5 μm diameter) by >99% (P < 0.001) and reduced airborne allergen concentration within the breathing zone (ratio of median counts = 30, P = 0.043). Treatment reduced inhaled allergen (ratio of median counts = 7, P = 0.043). Treatment was not associated with a change in airborne allergen concentration outside of the breathing zone (P = 0.160). Temperature-controlled laminar airflow treatment of individuals in an allergen-rich experimental environment results in significant reductions in breathing zone allergenic and non-allergenic particle exposure, and in inhaled cat allergen exposure. These findings may explain the clinical benefits of temperature-controlled laminar airflow.

Abstract
BACKGROUND Previous reports suggest that parents especially mothers of food-allergic children may have increased anxiety. Studies with an appropriate control group have not been undertaken, and the determinants of such anxiety are not known. We compared measures of anxiety and stress in mothers of food-allergic children and atopic non-food-allergic children, with anxiety and stress in mothers of children with no chronic illness. METHODS Cross-sectional study of mothers attending a hospital appointment for their 8- to 16-year-old child. Mothers of children with food allergy, asthma but no food allergy or no chronic illness completed questionnaires including State-Trait Anxiety Inventory, Perceived Stress Scale and measures of anxiety and psychologic adjustment in their child. RESULTS Forty mothers of food-allergic children, 18 mothers of asthmatic children without food allergy and 38 mothers of children with no chronic illness (controls) were recruited. Mothers of food-allergic children showed increased state anxiety – median anxiety score 38.0 (IQR 30.0, 44.0) food allergy, 27.0 (22.0, 40.0) control p = 0.012; and increased stress – median stress score 18.5 (12.0, 22.0) food allergy, 14.0 (7.5, 19.5)control p = 0.035. No significant differences were seen between mothers in the asthmatic group and controls. In multivariate analysis, previous food anaphylaxis(p = 0.008) and poorly controlled asthma (p = 0.004) were associated with increased maternal anxiety. Child anxiety and adjustment did not differ between food-allergic and control groups. CONCLUSIONS Mothers of food-allergic children have increased anxiety and stress compared with mothers of children with no chronic illness. Anaphylaxis and poorly controlled asthma are associated with maternal anxiety.

Abstract
Factors associated with failure of antifungal therapy were examined in 42 cancer patients with fusariosis (1987-1997). Thirty-six patients (86%) had leukemia and 39 (93%) were neutropenic. Disseminated infection was the most common presentation. The majority (83%) received amphotericin B-based therapy. Thirty patients (71%) failed therapy. No patient with persistent neutropenia responded.

Abstract
OBJECTIVES To identify the predictors of early childhood caries and urgent dental treatment need among primarily African-American children in child care centers in the Delta region of Mississippi. The purpose of this study was to replicate predictors of caries and urgent dental treatment needs that were identified in an earlier study conducted in Delta child care centers and to assess additional caries risk factors not collected in the original study. METHODS Children in 19 child care centers were examined by the dentists, and the parents provided data on oral health practices, oral health history, and on children's oral health-related quality of life (QOL). The dentists also assessed visible plaque and tested levels of mutans streptococci. Predictors of caries and treatment need among children 24 to 71 months of age were examined using logistic regression. RESULTS Two parent predictors of caries identified in the earlier study (parent flossing and soft/sugary drink consumption) were not predictive in the current study. Parent history of abscess continued to predict their child's urgent need for treatment. Young children's level of salivary mutans streptococci, maxillary incisor visible plaque, and parents' reports of child oral health-related QOL measures predicted the presence of both caries and urgent treatment need. Some expected predictors, such as frequency of child's toothbrushing, were not predictive of caries. CONCLUSIONS Parental abscess and parent's report of the child's oral health-related OOL are risk indicators for poor oral health outcomes that could be used by nondental personnel to identify young children in need of early preventive intervention and dental referral

Abstract
Simultaneously drawn quantitative blood cultures are used to diagnose catheter-related bloodstream infections. We conducted this study to determine the frequency with which central venous catheters were the source of bloodstream infections detected through paired positive blood cultures drawn from cancer patients and the potential for quantitative blood cultures to help predict outcome in neutropenic and non-neutropenic patients. From September 1999 to November 2000, we identified 169 patients with bloodstream infections. Of all bloodstream infections, 56% were catheter-related bloodstream infections. Gram-positive bacteremia was found to be catheter-related in 55% and 69% of patients with hematologic malignancy and solid tumors, respectively, whereas gram-negative bacteremia was catheter-related in only 19% of patients with underlying hematologic malignancy and in 60% of patients with solid tumor (P = 0.01). By multivariate analysis, poor response was associated with critical illness and persistent neutropenia (P < 0.01). In neutropenic patients with catheter-related bloodstream infections, peripheral quantitative blood cultures of >or=100 CFU/mL was also associated with poor response (P = 0.05). Central venous catheters were the major source of bloodstream infection, particularly in patients with solid tumors. In addition to critical illness and persistent neutropenia, quantitative blood cultures might be useful in predicting outcomes for neutropenic patients with catheter-related bloodstream infections.

Abstract
OBJECTIVES For poor and minority young children, disparities exist in dental health and treatment. In rural impoverished areas, institutions that reach young children and potentially offer access to care are limited. In the current Mississippi Delta study, child care centers were examined as potential venues for oral health intervention and research, and potential risk factors for dental caries and treatment urgency in high-risk preschool children were explored. METHODS Child care centers were selected and attending children recruited. Data on oral health practices were collected from surveys of center directors and parents/caregivers. Children were examined for caries and treatment urgency at centers by dentists. Bivariate and multivariate analyses with a 0. 05 alpha were used to examine data. RESULTS A total of 346 preschool children at 15 participating centers were examined: 46% were female, 68% minority. Minority children and those with public insurance were more than twice as likely to have caries and urgent treatment needs as non-minorities or those with private insurance. The odds of children having caries were half as great if parents reported using floss and nearly twice as great if the parent had experienced a dental abscess. For every soft drink the parent consumed daily, the odds of dental caries for children increased by 44%. CONCLUSIONS Conducting oral health exams and research in child care venues was possible, yet presented challenges. The combined use of two parental variables, reported soft drink consumption and abscess history, appears promising for caries prediction. Implementation of oral health programs and research in child care venues merits further exploration.

Abstract
Between February 1994 and November 1998, 56 oncology patients infected with vancomycin-resistant enterococci (VRE) were treated with quinopristin-dalfopristin (Q-D) plus minocycline (MIN). Infections included bacteremia, urinary tract infection, pneumonia, and wound infection. The response rate was 68%, and the most frequent adverse event was arthralgia or myalgia (36%). Q-D-MIN is effective for VRE infection in cancer patients but is associated with a substantial frequency of arthralgia or myalgia.

Abstract
Between November 1996 and February 1997, 17 episodes of vancomycin-resistant enterococci (VRE) infection or colonization (9 infections, 8 colonizations), all with the same or a similar genomic DNA pattern, were identified in the medical intensive care unit (MICU) of a tertiary-care cancer hospital. The cases were genotypically traced to a patient who was admitted to the hospital in September 1996 and who, by December 1996, had four different admissions to the MICU. Multifaceted infection control measures, including decontamination of the environment and of nondisposable equipment, halted the nosocomial transmission of VRE in the MICU.

Abstract
BACKGROUND Nosocomial pneumonia continues to be associated with high morbidity and mortality in cancer patients. METHODS In an attempt to find an optimal treatment for this infection, nonneutropenic cancer patients with postoperative nosocomial pneumonia were randomized to receive either piperacillin/tazobactam (P/T) 4.5 g i.v. every 6 hours (30 patients) or clindamycin (Cl) 900 mg plus aztreonam (Az) 2 g i.v. every 8 hours (22 patients). Amikacin 500 mg i.v. every 12 hours was given to all patients for the first 48 hours. RESULTS The two groups were comparable for the characteristics of pneumonia that included gram-negative etiology and duration of intubation. Response rates were 83% for patients who received P/T and 86% for those who received Cl/Az (P > .99). There were no serious adverse events; however, at our center the cost of the P/T regimen was $73.86 compared with $99.15 for the Cl/Az regimen. CONCLUSIONS The two regimens had comparable high efficacy, and P/T had a slight cost advantage. Either of these antibiotic regimens combined with an aminoglycoside could lead to favorable outcome in cancer patients at high risk for nosocomial pneumonia.

Abstract
OBJECTIVES To examine the efficacy of bladder catheters impregnated with minocycline and rifampin in reducing catheter-associated bacteriuria. METHODS A prospective, randomized clinical trial was conducted at five academic medical centers. Patients undergoing radical prostatectomy were randomized to receive intraoperatively either regular silicone bladder catheters (control catheters) or silicone bladder catheters impregnated with minocycline and rifampin (antimicrobial-impregnated catheters). Catheters remained in place for a mean of 2 weeks. Urine cultures were obtained at about 3, 7, and 14 days after catheter insertion. Bacteriuria was defined as the growth of organism(s) in urine at a concentration of 10(4) colony-forming units per milliliter or greater. RESULTS Kaplan-Meier analysis demonstrated that it took significantly longer for patients (n = 56) who received the antimicrobial-impregnated catheters to develop bacteriuria than those (n = 68) who received the control catheters (P = 0.006 by the log-rank test). Patients who received the antimicrobial-impregnated catheters had significantly lower rates of bacteriuria than those in the control group both at day 7 (15.2% versus 39.7%) and at day 14 (58.5% versus 83.5%) after catheter insertion. Patients who received the antimicrobial-impregnated catheters had significantly lower rates of gram-positive bacteriuria than the control group (7.1% versus 38.2%; P <0.001) but similar rates of gram-negative bacteriuria (46.4% versus 47.1%) and candiduria (3.6% versus 2.9%). The antimicrobial-impregnated catheters provided zones of inhibition against Enterococcus faecalis and Escherichia coli, both at baseline and on removal. CONCLUSIONS Bladder catheters impregnated with minocycline and rifampin significantly reduced the rate of gram-positive catheter-associated bacteriuria up to 2 weeks after catheter insertion.

Abstract
Vascular catheters impregnated with antimicrobial agents have been shown to decrease the risk of catheter-related colonization and bloodstream infections. Various antimicrobials and antiseptics have been used. In a recent meta-analysis of 12 studies, catheters coated with chlorhexidine and silver sulfadiazine (CH/SS) were shown to be significantly less likely to be associated with catheter-related bloodstream infections than uncoated catheters. However, these catheters were coated only on the external surface and they are associated with short antimicrobial durability (3-7 days). In addition, anaphylactic reactions to them were reported in Japan. Vascular catheters impregnated with minocycline and rifampin (M/R) were found to be highly efficacious in preventing catheter-related infections. In a recent prospective, randomized trial, the likelihood of catheter-related bloodstream infections associated with the use of M/R catheters was one-twelfth of that observed with catheters coated with CH/SS. The M/R catheters are coated on the external and internal surfaces and have an antimicrobial durability of 4 weeks. Although no resistance to either minocycline or rifampin has been seen in two trials, further studies are required to determine whether the risk of resistance outweighs the benefits derived from their use. In conclusion, antimicrobial catheters have been shown to be highly cost effective in decreasing the risk of catheter-related bloodstream infection.

Abstract
BACKGROUND The use of central venous catheters impregnated with either minocycline and rifampin or chlorhexidine and silver sulfadiazine reduces the rates of catheter colonization and catheter-related bloodstream infection as compared with the use of unimpregnated catheters. We compared the rates of catheter colonization and catheter-related bloodstream infection associated with these two kinds of antiinfective catheters. METHODS We conducted a prospective, randomized clinical trial in 12 university-affiliated hospitals. High-risk adult patients in whom central venous catheters were expected to remain in place for three or more days were randomly assigned to undergo insertion of polyurethane, triple-lumen catheters impregnated with either minocycline and rifampin (on both the luminal and external surfaces) or chlorhexidine and silver sulfadiazine (on only the external surface). After their removal, the tips and subcutaneous segments of the catheters were cultured by both the roll-plate and the sonication methods. Peripheral-blood cultures were obtained if clinically indicated. RESULTS Of 865 catheters inserted, 738 (85 percent) produced culture results that could be evaluated. The clinical characteristics of the patients and the risk factors for infection were similar in the two groups. Catheters impregnated with minocycline and rifampin were 1/3 as likely to be colonized as catheters impregnated with chlorhexidine and silver sulfadiazine (28 of 356 catheters [7.9 percent] vs. 87 of 382 [22.8 percent], P<0.001), and catheter-related bloodstream infection was 1/12 as likely in catheters impregnated with minocycline and rifampin (1 of 356 [0.3 percent], vs. 13 of 382 [3.4 percent] for those impregnated with chlorhexidine and silver sulfadiazine; P<0.002). CONCLUSIONS The use of central venous catheters impregnated with minocycline and rifampin is associated with a lower rate of infection than the use of catheters impregnated with chlorhexidine and silver sulfadiazine.
