Abstract
Introduction: Human milk is the preferred source of enteral nutrition for very low birthweight (VLBW) infants, and it possibly decreases dependence on parenteral nutrition (PN) and reduces incidence of late-onset sepsis (LOS). No systematic review to date has specifically addressed the value of early versus late introduction of human milk diet (HMD) on duration of PN and incidence of LOS among VLBW infants. Objective: To review the evidence for an early versus late introduction of HMD on duration of PN and incidence of LOS in VLBW infants. Method: Preferred reporting items for systematic reviews and meta-analysis-guided search of EMBASE and PubMed/Medline databases was conducted for this systematic review using phrases addressing population, intervention, comparator, and outcome framework to identify articles published over the past two decades without language restrictions. Full-text articles (both observational and randomized) that studied an early versus late initiation of HMD were included. Mean difference (MD) and relative risk (RR) with 95% confidence intervals (CIs) were calculated for PN and LOS. Quality of evidence was analyzed using UK National Service Framework and the risk-of-bias was assessed using Robvis®. Results: One randomized controlled trial (RCT) and two observational studies (two English and one Chinese) recruited 474 VLBW infants (455 analyzed). Among an intrauterine growth-restricted cohort enrolled in the RCT (n = 72), early HMD resulted in statistically significant reduction in PN dependence. However, no statistically significant difference was found in LOS. Two observational studies found similar reductions in PN duration and LOS incidence among the early HMD cohort. One observational study reported significant PN reduction; however, the incidence of LOS did not reach statistical significance in either case. Conclusion: An early HMD may reduce the duration of PN for a growth-restricted VLBW cohort. Observational studies suggesting reduced PN and LOS from early HMD endorse the need for bioactivity-focused human milk research. Variations in feeding guidelines among VLBW infants have the potential to influence neonatal outcomes significantly.

Antimicrobial Resistance Is Prevalent in E. coli and Other Enterobacterales Isolated from Public and Private Drinking Water Supplies in the Republic of Ireland. Microorganisms 2023; 11:1224. [PMID: 37317198 DOI: 10.3390/microorganisms11051224] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2023] [Revised: 05/02/2023] [Accepted: 05/04/2023] [Indexed: 06/16/2023] Open
Abstract
High levels of bacterial antimicrobial resistance (AMR) have been reported in many environmental studies conducted in Ireland and elsewhere. The inappropriate use of antibiotics in both human and animal healthcare as well as concentrations of residual antibiotics being released into the environment from wastewaters are thought to be contributing factors. Few reports of AMR in drinking water-associated microbes are available for Ireland or internationally. We analysed 201 enterobacterales from group water schemes and public and private water supplies, only the latter having been surveyed in Ireland previously. The organisms were identified using conventional or molecular techniques. Antimicrobial susceptibility testing for a range of antibiotics was performed using the ARIS 2X interpreted in accordance with EUCAST guidelines. A total of 53 Escherichia coli isolates, 37 Serratia species, 32 Enterobacter species and enterobacterales from seven other genera were identified. A total of 55% of isolates were amoxicillin resistant, and 22% were amoxicillin-clavulanic acid resistant. A lower level of resistance (<10%) was observed to aztreonam, chloramphenicol, ciprofloxacin, gentamicin, ceftriaxone and trimethoprim-sulfamethoxazole. No resistance to amikacin, piperacillin/tazobactam, ertapenem or meropenem was detected. The level of AMR detected in this study was low but not insignificant and justifies ongoing surveillance of drinking water as a potential source of antimicrobial resistance.

Abstract
OBJECTIVE To evaluate whether 1% aqueous chlorhexidine gluconate (CHG) when compared with 2% aqueous chlorhexidine gluconate is non-inferior for neonatal skin antisepsis. DESIGN Parallel, blinded, non-inferiority randomised trial. SETTING Level III, academic, neonatal intensive care unit. PATIENTS Infants born at 260/7 to 426/7 weeks of gestation from June 2019 to December 2019. INTERVENTIONS Participants were randomised to skin antisepsis by either 1% aqueous CHG or 2% aqueous CHG. MAIN OUTCOME MEASURES The primary outcome was the proportion of negative skin swab cultures after skin antisepsis. Secondary outcomes were local skin reactions at 0, 6, 12 and 24 hours and plasma chlorhexidine levels in a subset of the study population. RESULTS A total of 308 neonates with a median gestation age of 34 (31-37) weeks and mean birth weight of 2029 g were randomised on 685 occasions (1% CHG: n=341; 2% CHG: n=344). 93.0% of the post-antisepsis skin swabs were sterile in 1% CHG group compared with 95.6% of the swabs in the 2% CHG group (risk difference -2.7%, 95% CI -6.2% to +0.8%). The lower bound of 95% CI crossed the pre-specified absolute non-inferiority limit of 5%. Neonates developed mild dermatitis on 16 (2.3%) occasions. There was no significant difference in median plasma CHG levels in the two groups, 19.6 (12.5-36.4) and 12.6 (8.7-26.6) ng/mL, respectively. CONCLUSIONS Application of 1% aqueous CHG was not shown to be non-inferior to 2% chlorhexidine aqueous for skin antisepsis in neonates. There were no severe skin-related adverse events in either of the two groups.

Improving adherence to facility protocol and reducing blood culture contamination in an intensive care unit: A quality improvement project. Aust Crit Care 2020; 33:546-552. [PMID: 32417183 DOI: 10.1016/j.aucc.2020.03.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2019] [Revised: 01/14/2020] [Accepted: 03/01/2020] [Indexed: 11/23/2022] Open
Abstract
BACKGROUND Blood culture contamination (BCC) is a safety and quality indicator for intensive care units (ICUs). BCC rates in our ICU ranged from 2.90% to 6.70% in 2017. OBJECTIVE This quality improvement project aimed to reduce the contamination rate from a mean of 4.52% to <3.0% in 1 year by improving the adherence of nurses to the facility protocol during blood collection. METHODS This project used a before-after design. It was conducted by a leadership team in a 32-bed ICU where approximately 4000 cultures are drawn annually. We observed the performance of ICU nurses during blood collection, interviewed them regarding the difficulties they encountered with protocol adherence, and conducted a cause-and-effect analysis to identify the main problems. Based on a literature review, we developed and implemented a countermeasure protocol, including a standardised medical order, an online learning program, a weekly departmental report and individual feedback routine, and phlebotomy training to address these problems in 2 months. RESULTS The interview results indicated that blood contamination resulted from the environment, difficult phlebotomy, and the inadequate knowledge and skill of the nurses. The countermeasure protocol reduced the average BCC rate from 4.52% to 2.59% during the intervention period and to 0.59% during the 10-month postintervention period. Nursing adherence to the standard protocol for blood culture collection also improved. CONCLUSIONS BCC in ICUs is multifactorial. By optimising the work environment, offering skill training, and reinforcing education and individualised feedback, we successfully reduced BCC in our unit to a sustainable low rate.

Abstract
Background Staphylococcus aureus bacteraemia (SAB) is associated with relatively high risk of complications and high levels of mortality. Internationally, SAB management guidelines lack consensus and especially so regarding oncology patients. This is likely a reflection of insufficient randomised control trials (RCT) and the diversity of SAB patient populations. However, there are 2011 guidelines recommending a minimum of 14 days of appropriate IV antibiotic therapy for SAB. Objective We wished to determine whether our practice of shortened duration of intravenous antimicrobial therapy in favour of oral administration proved as effective as recommended guidelines in a mixed oncology patient cohort. Methods Retrospective review of patient records that included any SAB episode among oncology patients from January 2002 to December 2015. Medical chart reviews were undertaken to determine patient demographics, clinical management & antimicrobial therapy, duration of stay, presence of a central venous catheter (CVC) and outcome. Results Our CVC removal rate was just 73% in SAB where CVC was the identified source of infection, with an attributable mortality rate (<4%) far lower than would be expected. Antimicrobial therapy durations were considerably lower (10 days) than current recommendations of 14 days IV therapy. The recurrence rate of 15% was also significantly lower than has been reported previously. Conclusions Our observations contribute new insights concerning the management of SAB in oncology patients. Our findings suggest that therapeutic approaches should perhaps remain individualised and reflective of patient characteristics taking into consideration the complex nature of oncology patients.

Abstract
OBJECTIVE To assess the effectiveness of an online training platform for procedures among nurses in an internal medicine unit to reduce the number of contaminated blood cultures. METHOD This was a quasi-experimental pre-post intervention parallel group study. The sample consisted of internal medicine nurses in a tertiary hospital who participated in an online training program about blood culture extraction technique. Knowledge about the technique was measured pre- and post-intervention. Additionally, the study compared the number of blood cultures taken 6 months before and 3 months after the intervention. RESULTS Forty-eight nurses participated. Pre-intervention knowledge was homogeneous among both groups, improving significantly after the online training program (p=0.0001). The blood cultures taken prior to the training showed contamination levels above international standards; post-intervention, contamination levels fell by up to 3% in the intervention group. CONCLUSION The educational intervention using the digital platform increased knowledge about the procedure and its application in clinical practice.

Abstract
CONTEXT.— Specimen quality is paramount for microbiology culture in order to ensure the testing is performed appropriately and the results, generated accurately, reflect the patient's clinical situation and guide proper treatment. Several factors play a critical role in guaranteeing the accuracy of the culture results, including adequate specimen collection by the surgeon, proper labeling, and timely transport to the laboratory. OBJECTIVE.— To educate pathologists, surgeons, and other medical personnel involved in the collection and processing of surgical specimens submitted for microbiologic culture. To assure the pathogen is correctly identified, proper protocols must be followed. The accurate identification of the infectious microorganisms from surgical specimens is vital for the treating clinician to ensure the correct antimicrobial therapy is administered. DATA SOURCES.— An analysis of relevant literature was performed by using PubMed. Articles were selected on the basis of their relevance to the topic as well as their date of publication. Articles published between 2000 and 2018 were deemed sufficient for inclusion, while older references, regardless of relevance, were excluded. CONCLUSIONS.— The process of properly obtaining specimens for microbiology culture from the operating room is a complex process that requires collaboration between the collecting surgeon and the pathologist and microbiology laboratory in order to provide the highest quality of results from which important treatment decisions are then implemented. Engaging leadership to develop mutually agreed-upon institutional best practices will help not only to standardize practices but also to improve the quality of microbiology results reported.

Abstract
Background and aims: Blood culture (BC) remains gold standard for the evaluation and diagnosis of neonatal sepsis. Time when BC becomes positive and the type of microorganism isolated are crucial in deciding the antimicrobial management. Likely pathogenicity of organisms growing in BC could potentially be predicted based on the "time to positivity" (TTP). We aimed to estimate the predictive value of isolating a likely pathogenic organism depending on TTP; evaluate the aetiological trend and neonatal mortality rate due to culture-proven neonatal sepsis for over a decade and verify whether the application of a "36 hour rule" to discontinue empiric antibiotics in well newborn infants with negative BC would be safe.Methods: Retrospective review of BC results over a 14-year period from a regional neonatal unit in Ireland. Laboratory data were independently extracted in relation to BC results from the laboratory information management system (LIMS-iLAB). Neonatal mortality data were collected from multiple sources. Statistical analysis included logistic regression, chi-square, and Mann-Whitney U-test.Results: Over a 14-year period 11,432 neonatal BC specimens were incubated of which 605 (5.3%) turned positive. Overall, the commonest organism grown was coagulase-negative Staphylococcus (CoNS), 416 (68.8%). Main pathogenic organisms were Staphylococcus aureus 23 (3.8%), Enterococcus spp. 22 (3.6%), E.coli 21 (3.5%), group B Streptococcus (GBS) 18 (3.0%), and Klebsiella species 9 (1.5%). Gram-negative organisms had the shortest TTP, with Klebsiella spp. having a median TTP of 10 h and E. coli 11 h. For Gram-positives, GBS had a median TTP of 12 h, Enterococcus species 14 h, with S. aureus growing at a median time of 15 h. All of the Klebsiella spp. and other Coliforms were detected within 24 h, with, 95.2% of E.coli, 94.4% of GBS, 95.5% of Enterococci, and 95.7% of S. aureus, flagging positive in 24 h. Using logistic regression the omnibus test of the coefficients in the resulting model was significant (p < .001). Our observed coefficient (β) for TTP was 0.144; shorter the TTP higher was the likelihood of isolating a pathogenic organism, with an odds ratio (OR) of 1.155. We also report a relatively low blood culture proven sepsis-specific neonatal mortality rate of 0.403/1000 live births and in all such instances observed TTP was less than 24 h.Conclusion: Duration of this study exceeds that of most of the neonatal blood culture TTP analysis published to-date. A shorter TTP is an important adjunct to suggest the growth of a pathogenic organism while managing suspected neonatal sepsis. TTP if < 24 h per se would not necessarily confirm the growth of a highly pathogenic organism; however, if a positive growth is likely to happen for a significant neonatal pathogen, in more than 98% the TTP would be within 24 h. This offers the clinician more of negative predictive value than a positive one; when there is no growth in BC. Our observation on TTP reiterate the National Institute of Health and Care Excellence (NICE) guideline of discontinuation of empiric antibiotics after 36 h in and clinically well and BC negative newborn infants.

Abstract
BACKGROUND Platelet-rich plasma (PRP) is a concentrate of autologous blood growth factors which has been shown to provide some symptomatic relief in early osteoarthritis (OA) of the knee. The objective of this study was to test the feasibility and efficacy potential of platelet rich plasma (PRP) in primary care. METHODS Feasibility study to assess safety of the intervention procedures and assess primary and secondary outcome measures. Consecutive patients presenting with symptomatic knee OA were recruited in a primary care setting in Ireland. All participants received three injections of PRP 4 weeks apart. The following self-reported clinical outcomes were evaluated before and after therapy (4 months): Pain and disability (ICOAP questionnaire); health utility (EUROQol); adverse events; patient satisfaction and goal-orientated outcomes. RESULTS Seventeen potential patients were identified of whom 14 were eligible to participate. Twelve consented and completed the intervention and all outcome measures. There were no losses to follow-up. One patient reported pain and stiffness for 2 days after the first injection but did complete the study. No growth was detected from nine consecutive samples sent for microbiology analysis. Changes in constant, intermittent and total pain scores were reported; pain fully resolved in two patients. In addition, health utility, patient satisfaction and goal-orientated outcomes also demonstrated improvement. CONCLUSIONS Platelet-rich plasma therapy is a simple and minimally invasive intervention which is feasible to deliver in primary care to treat osteoarthritis of the knee joint. Well-designed randomised controlled trials are needed to measure outcomes, durability of effect and cost effectiveness.

Abstract
AIM The use of anaerobic blood cultures in infants suspected of bacteraemia is controversial. Our children's hospital uses both aerobic and anaerobic media, regardless of the risk of anaerobic infection, and the aim of this study was to re-evaluate the use of anaerobic cultures in infants. METHODS We collected retrospective data from 2002 to 2016 on all blood cultures taken from infants younger than 90 days in the Hadassah-Hebrew University Medical Centre, Jerusalem, Israel. The incidence and characteristics of infants with positive anaerobic blood cultures were assessed. RESULTS During the study period, 51 035 blood cultures were drawn from 44 304 infants. Of these, 1496 (2.9%) were clinically significant positive cultures. Pathogenic obligatory anaerobic bacteraemia was extremely rare, with only 37 positive cultures (0.07%) from all of the cultures drawn. No specific risk factors for obligatory anaerobic bacteraemia could be defined, but as many as 174 (11.6%) clinically significant isolates were only detected in the anaerobic culture bottle. CONCLUSION True anaerobic bacteraemia was extremely rare in neonates. Nevertheless, using anaerobic culture media may increase the overall yield of bacterial culture growth by isolating anaerobic-facultative bacteria. This should be weighed up against increasing the volume of blood used for the aerobic culture.
