"You go in heavy and you come out light": An interpretative phenomenological analysis of reflective practice experiences in an Irish infant mental health setting.

Reflective practice (RP) is a core component of infant mental health (IMH); however, there is limited published empirical research on IMH practitioner experiences of RP. This two-stage, qualitative, multimodal study explored Irish IMH practitioners' experiences of RP spaces. Visual and verbal data from seven individual interviews and a participatory arts-based focus group with seven participants (eight participants in total, all white Irish females) were analyzed using Interpretative Phenomenological Analysis. Five group experiential themes (Just get on with it; What should I be bringing to this space?; Who are my "hands"?; Taking a step back; and You go in heavy and you come out light) were generated by the analysis. These were used to construct a developmental and experiential model of learning in an RP space. The themes portray how a practitioner's RP experience can change over time: influenced by prior experiences and practice development stage, practitioners move from initial uncertainty, anxiety, and perceived pressure in a busy workload to developing the trust and ability to be vulnerable in an RP space. Through relationships (supervisor/facilitator or group members), a shared safe space can be created, which addresses practitioners' needs for containment, allowing for experiential learning through a process of transformational moments.

La práctica con reflexión (RP) es un componente central de la salud mental infantil (IMH), sin embargo, existe una limitada investigación empírica publicada sobre las experiencias de RP de los profesionales de la práctica de IMH. Este estudio multimodal, cualitativo, en dos etapas, exploró las experiencias de los espacios de RP de profesionales irlandeses en la práctica de IMH. Se analizó la información visual y verbal de siete entrevistas individuales y un grupo de enfoque participativo con base artística de siete participantes (ocho participantes en total, todas mujeres blancas irlandesas) usando el Análisis Fenomenológico Interpretativo. El análisis generó cinco temas de la experiencia de grupo (Manos a la obra; ¿Qué debo aportar a este espacio?; ¿Quiénes son mis 'manos'?; Dar un paso atrás; y Se comienza pesado y se termina liviano). Estos temas se usaron para construir un modelo de desarrollo y experimental de aprendizaje dentro de un espacio de RP. Los temas describieron cómo la experiencia de RP de un profesional de la práctica puede cambiar a lo largo del tiempo: influida por experiencias previas y un estado de desarrollo práctico, los profesionales de la práctica pasan de la incertidumbre inicial, la ansiedad y la percibida presión dentro de una ocupada carga de trabajo a desarrollar la confianza y la habilidad de ser vulnerable dentro de un espacio de RP. A través de relaciones (supervisor/facilitador o miembros de grupo), se puede crear un espacio seguro compartido, el cual aborda las necesidades de contención de los profesionales de la práctica, permitiendo el aprendizaje experimental a través de un proceso de momentos transformacionales.

Duplex recombinase polymerase amplification assays incorporating competitive internal controls for bacterial meningitis detection.

Recombinase polymerase amplification (RPA) is an isothermal nucleic acid amplification technology that provides rapid and robust infectious disease pathogen detection, ideal for point-of-care (POC) diagnostics in disease-prevalent low-resource countries. We have developed and evaluated three duplex RPA assays incorporating competitive internal controls for the detection of leading bacterial meningitis pathogens. Streptococcus pneumoniae, Neisseria meningitidis and Haemophilus influenzae singleplex RPA assays were initially developed and evaluated, demonstrating 100% specificity with limits of detection of 4.1, 8.5 and 3.9 genome copies per reaction, respectively. Each assay was further developed into internally controlled duplex RPA assays via the incorporation of internal amplification control templates. Clinical performance of each internally controlled duplex RPA assay was evaluated by testing 64 archived PCR-positive clinical samples. Compared to real-time PCR, all duplex RPA assays demonstrated 100% diagnostic specificity, with diagnostic sensitivities of 100%, 86.3% and 100% for the S. pneumoniae, N. meningitidis and H. influenzae assays, respectively. This study details the first report of internally controlled duplex RPA assays for the detection of bacterial meningitis pathogens: S. pneumoniae, N. meningitidis and H. influenzae. We have successfully demonstrated the clinical diagnostic utility of each duplex RPA assay, introducing effective diagnostic technology for POC bacterial meningitis identification in disease-prevalent developing countries.

The role of real-time PCR testing in the investigation of paediatric patients with community-onset osteomyelitis and septic arthritis.

BACKGROUND: Culture yield in osteomyelitis and septic arthritis is low, emphasising the role for molecular techniques. AIMS: The purpose of this study was to review the laboratory investigation of childhood osteomyelitis and septic arthritis. METHODS: A retrospective review was undertaken in an acute tertiary referral paediatric hospital from January 2010 to December 2016. Cases were only included if they had a positive culture or bacterial PCR result from a bone/joint specimen or blood culture, or had radiographic evidence of osteomyelitis. RESULTS: Seventy-eight patients met the case definition; 52 (66%) were male. The median age was 4.8 years. Blood cultures were positive in 16 of 56 cases (29%), with 11 deemed clinically significant (Staphylococcus aureus = 8, group A Streptococcus = 3). Thirty-seven of 78 (47%) bone/joint samples were positive by culture with S. aureus (n = 16), coagulase-negative Staphylococcus (n = 9) and group A Streptococcus (n = 4), being the most common organisms. Sixteen culture-negative samples were sent for bacterial PCR, and four were positive (Kingella kingae = 2, Streptococcus pneumoniae = 1, group A Streptococcus = 1). CONCLUSIONS: Sequential culture and PCR testing can improve the detection rate of causative organisms in paediatric bone and joint infections, particularly for fastidious microorganisms such as K. kingae. PCR testing can be reserved for cases where culture is negative after 48 h. These results have been used to develop a standardised diagnostic test panel for bone and joint infections at our institution.

Evaluation of the Clinical Utility of a Real-time PCR Assay for the Diagnosis of Streptococcus pneumoniae Bacteremia in Children: A Retrospective Diagnostic Accuracy Study.

BACKGROUND: The widespread uptake of pneumococcal vaccines has substantially reduced the incidence of invasive pneumococcal disease, such that pneumococcal bacteremia in children is now considered a relatively rare event. The objective of this study was to ascertain the clinical utility of a Streptococcus pneumoniae real-time polymerase chain reaction (PCR) assay compared with standard blood culture for the diagnosis of pneumococcal bacteremia in children in the post-vaccine era. METHODS: A systematic retrospective review of laboratory and patient records from Children's University Hospital, Temple Street, during a 6-year period was performed. Paired blood PCR and blood culture specimens from children younger than 16 years of age were investigated. Statistical analysis was performed to measure the diagnostic accuracy of PCR versus routine bacterial culture techniques. RESULTS: More than 1900 PCR test requests were examined from 2010 to 2015, of which 1561 paired PCR and blood culture specimens met criteria for inclusion in the statistical analysis. The PCR assay demonstrated high specificity (99%, confidence interval 95%: 98.81%-99.69%); however, the sensitivity was low compared with that of blood culture (47%, confidence interval 95%: 21.27%-73.41%). Investigation of 10 PCR-positive/culture-negative cases revealed that these cases ranged from definite, probable, and possible significance, indicating a low false positivity rate associated with the assay. CONCLUSION: This study demonstrates the limited utility of blood PCR testing for S. pneumoniae in pediatric patients without radiographic evidence pneumonia or empyema. Moreover, we report that PCR may be a useful diagnostic tool when blood cultures are negative because of antimicrobial therapy before sampling. Given that the incidence of pneumococcal disease has decreased considerably in recent years, justification of S. pneumoniae PCR requisition is necessary. Hence, new guidelines for pediatric pneumococcal blood PCR testing have been introduced at the Irish Meningitis and Sepsis Reference Laboratory.

Clinical Utility of Polymerase Chain Reaction Testing for Streptococcus pneumoniae in Pediatric Cerebrospinal Fluid Samples: A Diagnostic Accuracy Study of More Than 2000 Samples From 2004 to 2015.

The aim of this retrospective study was to review the diagnostic accuracy of real-time polymerase chain reaction (PCR) testing of cerebrospinal fluid (CSF) samples for Streptococcus pneumoniae DNA in comparison with traditional bacterial culture. The hypothesis was that PCR is more sensitive than culture and would detect more cases of pneumococcal meningitis, particularly in children treated with antimicrobials before CSF sampling occurred. Patients younger than 16 years of age who had a CSF sample tested for S. pneumoniae DNA by PCR between 2004 and 2015 were included. A total of 2025 samples were included, and the PCR had a sensitivity of 100% and specificity of 98% for the detection of S. pneumoniae DNA in comparison with culture. Of the 28 culture negative/PCR positive cases, 25 (89%) were probable meningitis cases and only 3 (11%) were suspected false positive results. Nineteen (76%) of the 25 probable cases required ICU admission, and 3 died (12%). Six different serotypes were found in the culture positive patients (18C, 6B, 14, 22F, 7F and 33F). This study demonstrates that PCR testing of CSF samples for S. pneumoniae is sensitive and specific when compared with culture. PCR is particularly useful in detecting those cases where culture is negative, perhaps relating to pre-CSF sampling administration of antimicrobials.

The impact of meningococcal polymerase chain reaction testing on laboratory confirmation of invasive meningococcal disease.

Laboratory methods of diagnosis were examined for 266 children with invasive meningococcal disease. Seventy-five (36%) of 207 cases with bloodstream infection had both positive blood culture and blood meningococcal polymerase chain reaction (PCR), 130 (63%) negative blood culture and positive blood PCR, and 2 (1%) had positive blood culture and negative blood PCR. Sixty-three percent of cases were diagnosed by PCR alone.
