Urinary tract infections in very premature neonates: the definition dilemma.

BACKGROUND AND OBJECTIVES: Data on urinary tract infections (UTIs) in very preterm neonates (VPTNs) are scarce. We aimed to (i) describe the characteristics of UTIs in VPTNs and (ii) compare the diagnostic practices of neonatal clinicians to established pediatric guidelines. METHODS: All VPTNs (<29 weeks GA) with a suspected UTI at the CHU Sainte-Justine neonatal intensive care unit from January 1, 2014, and December 31, 2019, were included and divided into two definition categories: Possible UTI, and Definite UTI. RESULTS: Most episodes were Possible UTI (87%). Symptoms of UTIs and pathogens varied based on the definition category. A positive urinalysis was obtained in 25%. Possible UTI episodes grew 2 organisms in 62% of cases and <50,000 CFU/mL in 62% of cases. CONCLUSION: Characteristics of UTIs in VPTNs vary based on the definition category and case definitions used by clinicians differ from that of established pediatric guidelines.

The holistic maternity care needs of women with Gestational Diabetes Mellitus: A systematic review with thematic synthesis.

PROBLEM: Models of care for women with gestational diabetes mellitus (GDM) have evolved in an ad hoc way and do not meet women's needs. BACKGROUND: GDM affects 50,000 Australian women per annum with prevalence quadrupling in the last ten years. Many health services are struggling to provide a quality service. People with diabetes are calling for care that focuses on their wellbeing more broadly. AIM: To examine the holistic (emotional, social, economic, and spiritual) care needs of women with GDM. METHODS: Qualitative and mixed-methods studies capturing the healthcare experiences of women with GDM were searched for in CINAHL, Medline, Web of Science and Scopus. English-language studies published between 2011 and 2023 were included. Quality of studies was assessed using Crowe Critical Appraisal Tool and NVIVO was used to identify key themes and synthesise data. FINDINGS: Twenty-eight studies were included, representing the experiences of 958 women. Five themes reflect women's holistic needs through their journey from initial diagnosis to postpartum: psychological impact, information and education, making change for better health, support, and care transition. DISCUSSION: The biomedical, fetal-centric model of care neglects the woman's holistic wellbeing resulting in high levels of unmet need. Discontinuity between tertiary and primary services results in a missed opportunity to assist women to make longer term changes that would benefit themselves (and their families) into the future. CONCLUSIONS: The provision of holistic models of care for this cohort is pivotal to improving clinical outcomes and the experiences of women with GDM.

Exploration de l'association possible entre la consommation d'antibiotiques et l'émergence de résistance dans un centre hospitalier universitaire mère-enfant.

Background: The emergence of antibiotic resistance has contributed to the development of multidrug-resistant bacteria, which is a major concern. Objectives: The primary objective was to explore the possible association between antibiotic use and the emergence of resistance in a mother-child university hospital. Method: This retrospective study was conducted in a university hospital centre. Antibiotic-bacteria pairs were established, taking into account the number of isolates, actual antibiotic use, and clinical relevance. For each pair, a comparison of 2 variables (antibiotic utilization and rate of resistance) was quantified with the Pearson coefficient. Three analyses were conducted: no lag between utilization and resistance, 1-year lag, and 2-year lag. Results: Thirty antibiotic-bacteria pairs were selected from hematology-oncology and 18 from neonatology. In hematology-oncology, 6 pairs had a positive correlation (Pearson coefficient > 0.7): 2 pairs involving meropenem, 2 involving ceftazidime, and 2 involving piperacillin-tazobactam. In 3 of these cases, there was no lag between consumption of antibiotics and presence of resistance. In neonatology, 3 antibiotic-bacteria pairs had a positive correlation, 1 each involving vancomycin, cloxacillin, and meropenem. Conclusions: It is possible to explore the potential association between consumption of antibiotics and emergence of resistance in a particular centre. Our exploratory approach was based on manual data processing. It would be interesting to consider a continuous systematic approach, allowing automatic generation of correlations.

Practice Summary of Antimicrobial Therapy for Commonly Encountered Conditions in the Neonatal Intensive Care Unit: A Canadian Perspective.

Neonates are highly susceptible to infections owing to their immature cellular and humoral immune functions, as well the need for invasive devices. There is a wide practice variation in the choice and duration of antimicrobial treatment, even for relatively common conditions in the NICU, attributed to the lack of evidence-based guidelines. Early decisive treatment with broad-spectrum antimicrobials is the preferred clinical choice for treating sick infants with possible bacterial infection. Prolonged antimicrobial exposure among infants without clear indications has been associated with adverse neonatal outcomes and increased drug resistance. Herein, we review and summarize the best practices from the existing literature regarding antimicrobial use in commonly encountered conditions in neonates.

Using health information technology in residential aged care homes: An integrative review to identify service and quality outcomes.

OBJECTIVE: To identify outcomes of using health information technologies to support direct resident care in residential aged care homes, for residents, staff and services. METHODS: In May 2022, a systematic search used CINAHL, Cochrane CRCT, MEDLINE, Proquest, PsychINFO and Scopus databases to locate papers published after 1990. Thematic analysis was used to synthesise extracted data. Results are reported using the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) statement. RESULTS: Of 3721 references imported for screening, 1017 duplicates were removed and 2609 excluded, leaving 95 papers for data extraction. The included articles were conducted in diverse residential care homes, and involved over 12,000 nurse, care assistant or resident participants. Thematic analysis identified a range of health information technologies were used for direct care in residential care settings, and outcomes focussed on acceptability, efficiency and success of implementation. Less frequent were outcomes focussed on residents and families, and the safety and quality-of-care delivery. DISCUSSION: Staff outcomes, focussed on the satisfaction of staff and usability of the system, dominate in research examining health information technology used for direct care in residential aged care homes. Outcomes examining the use of health information technology in delivering improvements in resident health, well-being, quality and safety was limited. There is a need to increase using quality and safety of resident care as outcome measures.

Establishing Benchmarks for Antimicrobial Use in Canadian Children's Hospitals: Results From 2 National Point Prevalence Surveys.

BACKGROUND: Point prevalence surveys (PPS) are potentially useful to measure antimicrobial use across institutions. The objectives of the study were to describe and compare antimicrobial use between pediatric hospitals in Canada. METHODS: Fifteen pediatric hospitals all with pediatric infectious diseases service participated in 2 single-day PPS in 2018/19. Children <18 years of age who were inpatients were included. Age, service, clinical diagnosis as well as name, route, and start date for each antimicrobial was collected. Antibiotics were grouped according to the World Health Organization AWaRe classification. RESULTS: There were 3924 inpatient patients-days representing 2729 children and 1195 infants in neonatal intensive care units (NICU) surveyed. Among non-NICU patients, 1210 (44.3%) received 1830 antimicrobials of which 73.9% were for empiric or pathogen-directed therapy and 25.6% for prophylaxis. The mean proportion of core Access and Watch group antibiotics was 45.8% and 63.5%, respectively, with no differences in means between tertiary and quaternary care sites. Among 1195 infants in NICU, 19.7% received 410 antimicrobials of which 17.1% were for prophylaxis and a mean of 45.4% were Watch group antibiotics. Of patients admitted for community-acquired pneumonia, 32.7% received penicillin or aminopenicillins only with variability among sites. CONCLUSIONS: PPS of antimicrobial use in Canadian pediatric hospitals revealed a high proportion of Watch group (broader spectrum) antibiotics, even among children with community-acquired pneumonia. This study demonstrates the feasibility of PPS to document antimicrobial use and potentially to use this data to establish goals for decreasing both overall and Watch group antibiotics.

Combined influence of practice guidelines and prospective audit and feedback stewardship on antimicrobial treatment of community-acquired pneumonia and empyema in children: 2012 to 2016.

BACKGROUND: Aminopenicillins are recommended empiric therapy for community-acquired pneumonia (CAP). The aim of the study was to assess treatment over a 5-year period after CAP guideline publication and introduction of an antimicrobial stewardship program (ASP). METHODS: Using ICD-10 discharge codes for pneumonia, children less than 18 years admitted to the Children's Hospital of Eastern Ontario January 1, 2012 and December 31, 2016 were identified. Children ≥ 2 months with consolidation were included. One day of therapy (DOT) was one or more doses of an antimicrobial given for 1 day. RESULTS: Of 1,707 patients identified, 713 met inclusion criteria. Eighteen (2.5%) had bacteria identified by culture and 79 of 265 (29.8%) had Mycoplasma pneumoniae detected. Mean DOT/1,000 patient days of aminopenicillins/penicillin (AAP) increased by 18.1% per year (95% confidence interval [CI] -0.2, 39.9%) and decreased by 37.6% per year (95% CI -56.1, -11.3%) for second- and third-generation cephalosporins in the post-ASP period. The duration of discharge antimicrobials decreased. Of 74 (10.4%) patients who had pleural fluid drained, 35 (47.3%) received more than 5 days of AAP and ≤ 5 days of second-/third-generation cephalosporins with no difference in median length of stay nor mean duration of antimicrobials. CONCLUSIONS: Implementation of CAP management guidelines followed by prospective audit and feedback stewardship was associated with a sustained decrease in the use of broad-spectrum antibiotics in childhood CAP. Use of AAP should also be strongly considered in patients with effusions (even if no pathogen is identified), as clinical outcome appears similar to patients treated with broad-spectrum antimicrobials.

Uncommon clinical presentation of a common bug: Group A Streptococcus meningitis.

Group A Streptococcus (GAS) is a common pathogen in paediatric infections. However, it is a rare etiologic agent of bacterial meningitis. We describe a case of Streptococcus pyogenes meningitis complicated by sensorineural hearing loss in an immunocompetent 7-year-old boy. Clinicians should be aware of GAS as a potential cause of paediatric meningitis, especially with prominent symptoms suggestive of frontal sinusitis. Meningitis caused by GAS has been shown to be associated with significant mortality and morbidity, including neurological complications. Early screening for sensorineural hearing loss in patients with GAS meningitis can facilitate timely cochlear implant.

High-dose steroid and heparin: a novel therapy for cerebral vasculitis associated with presumed group A Streptococcus meningitis.

Cerebral vasculitis is a serious complication of bacterial meningitis that can cause significant morbidity and mortality due to stroke. Currently, there are no treatment guidelines or safety and efficacy studies on the management of cerebral vasculitis in this context. Herein, we report a case of a previously well 11-year-old girl who presented with acute otitis media that progressed to mastoiditis and fulminant meningitis. Group A Streptococcus was found in blood and ear-fluid cultures (lumbar puncture was unsuccessful). Her decreased level of consciousness persisted despite appropriate antimicrobial treatment, and repeat MRI revealed extensive large vessel cerebral vasculitis. Based on expert opinion and a presumed inflammatory mechanism, her cerebral vasculitis was treated with 7 days of pulse intravenous methylprednisolone followed by oral prednisone taper. She was also treated with intravenous heparin. Following these therapies, she improved clinically and radiographically with no adverse events. She continues to undergo rehabilitation with improvement.

Vancomycin drug monitoring in infants with CoNS sepsis-target attainment, microbiological response and nephrotoxicity.

OBJECTIVES: To characterize residual vancomycin concentrations (Cmin) and assess the relationships between Cmin, the risk of nephrotoxicity and persistent CoNS sepsis. METHODS: In this 5-year retrospective study among infants treated with vancomycin, the primary outcome was the proportion of those with a steady state Cmin between 10 and 20 mg/L. The secondary outcomes were nephrotoxicity and persistent CoNS sepsis. RESULTS: Of 120 infants included, the median first steady state Cmin was 12.4 mg/L and 77 (64%) had a Cmin between 10 and 20 mg/L. Six percent developed nephrotoxicity. This risk was not associated with Cmin. Of the 30 infants with CoNS sepsis, 17 (57%) had persistent bacteremia, and this risk did not correlate significantly with Cmin, CoNS minimal inhibitory concentration (MIC) for vancomycin, or Cmin/MIC. CONCLUSIONS: The majority of infants achieved targeted levels of vancomycin, but persistent bacteremia was common. We did not identify a Cmin threshold associated with nephrotoxicity, nor with microbiological clearance.

Prevalence and predictors of restrictive interventions in a youth-specific mental health inpatient unit.

INTRODUCTION: The use of restrictive interventions is one of the most controversial practices in medicine. They are utilized in an inpatient setting to manage agitated or aggressive behaviour or to ensure that an individual receives the necessary treatments. However, restrictive interventions remove autonomy and adverse events can be associated with their practice. Youth-specific inpatient units (IPUs) are now being established and it is imperative that the use of restrictive interventions is reduced. In order to inform and facilitate prevention and reduction strategies, this study aimed to determine the prevalence and determinants of restrictive interventions (restraint, seclusion and medication without consent) in a youth specialist mental health IPU. METHODS: This study was set at a 16-bed youth specialist acute IPU of Orygen Youth Health, a specialist youth mental health service that provides inpatient care for those aged 18 to 25 years within a catchment area of west and north-western regions of Melbourne, Australia. A retrospective file audit was conducted of all the admissions to the unit from 01 January 2015 to 30 June 2015. RESULTS: Over the 6-month study period, 159 young people were admitted and this accounted for 188 admissions. Over half (54.3%) of admissions were involuntary and restrictive intervention were used in 17.6% of admissions. Specifically, 15.7% (N = 25) of young people experienced restraint, 10.1% (N = 16) were secluded, and 8.1% (N = 12) experienced medication without consent. Absent insight and involuntary status on admission were associated with restrictive interventions. CONCLUSION: As youth mental health services develop, interventions aimed at reducing restrictive interventions are needed.

Educating Mental Health Clinicians About Sensory Modulation to Enhance Clinical Practice in a Youth Acute Inpatient Mental Health Unit: A Feasibility Study.

There is an emergence of literature describing effective sensory modulation (SM) interventions to de-escalate violence and aggression among mental health inpatients. However, the evidence is limited to adult settings, with the effect of SM in youth acute settings unknown. Yet, before SM may be used as a de-escalation intervention in youth acute settings, multidisciplinary staff need to be educated about and supported in the clinical application of SM. In the current study, an online SM education package was developed to assist mental health staff understand SM. This was blended with action learning sets (ALS), small group experiential opportunities consisting staff and consumers to learn about SM resources, and the support of SM trained nurses. The aims of the study were to evaluate the effectiveness of this SM education intervention in (a) transferring knowledge of SM to staff, and (b) translating this knowledge into practice in a youth acute inpatient mental health unit. A mixed methods research design with an 11-item pre- and post-education questionnaire was used along with three-month follow-up focus groups. The SM education improved understanding about SM (all 11-items p ≤ 0.004, r ≥ 0.47). Three-months after SM education, four themes evident in the focus group data emerged about the practice and process of SM; (1) translating of learning into practice, (2) SM in practice, (3) perceptions of SM benefits, and (4) limitations of SM. A blended SM education process enhanced clinical practice in the unit, yet participants were mindful of limitations of SM in situations of distress or escalating agitation.

Synergistic combinations of the CCR5 inhibitor VCH-286 with other classes of HIV-1 inhibitors.

Here, we evaluated the in vitro anti-HIV-1 activity of the experimental CCR5 inhibitor VCH-286 as a single agent or in combination with various classes of HIV-1 inhibitors. Although VCH-286 used alone had highly inhibitory activity, paired combinations with different drug classes led to synergistic or additive interactions. However, combinations with other CCR5 inhibitors led to effects ranging from synergy to antagonism. We suggest that caution should be exercised when combining CCR5 inhibitors in vivo.

Carbapenem disks on MacConkey agar in screening methods for detection of carbapenem-resistant Gram-negative rods in stools.

Direct plating of simulated stool specimens on MacConkey agar (MCA) with 10-µg ertapenem, meropenem, and imipenem disks allowed the establishment of optimal zone diameters for the screening of carbapenem-resistant Gram-negative rods (CRGNR) of ≤ 24 mm (ertapenem), ≤ 34 mm (meropenem), and ≤ 32 mm (imipenem).
