Electrophysiological correlates of symbolic numerical order processing

by Clemens Brunner, Philip Schadenbauer, Nele Schröder, Roland H. Grabner, Stephan E. Vogel

Determining if a sequence of numbers is ordered or not is one of the fundamental aspects of numerical processing linked to concurrent and future arithmetic skills. While some studies have explored the neural underpinnings of order processing using functional magnetic resonance imaging, our understanding of electrophysiological correlates is comparatively limited. To address this gap, we used a three-item symbolic numerical order verification task (with Arabic numerals from 1 to 9) to study event-related potentials (ERPs) in 73 adult participants in an exploratory approach. We presented three-item sequences and manipulated their order (ordered vs. unordered) as well as their inter-item numerical distance (one vs. two). Participants had to determine if a presented sequence was ordered or not. They also completed a speeded arithmetic fluency test, which measured their arithmetic skills. Our results revealed a significant mean amplitude difference in the grand average ERP waveform between ordered and unordered sequences in a time window of 500–750 ms at left anterior-frontal, left parietal, and central electrodes. We also identified distance-related amplitude differences for both ordered and unordered sequences. While unordered sequences showed an effect in the time window of 500–750 ms at electrode clusters around anterior-frontal and right-frontal regions, ordered sequences differed in an earlier time window (190–275 ms) in frontal and right parieto-occipital regions. Only the mean amplitude difference between ordered and unordered sequences showed an association with arithmetic fluency at the left anterior-frontal electrode. While the earlier time window for ordered sequences is consistent with a more automated and efficient processing of ordered sequential items, distance-related differences in unordered sequences occur later in time.

Objectives

Daily calcium supplements are recommended for pregnant women from 20 weeks’ gestation to prevent pre-eclampsia in populations with low dietary calcium intake. We aimed to improve understanding of barriers and facilitators for calcium supplement intake during pregnancy to prevent pre-eclampsia.

Design

Mixed-method systematic review, with confidence assessed using the Grading of Recommendations, Assessment, Development and Evaluations-Confidence in the Evidence from Reviews of Qualitative research approach.

Data sources

MEDLINE and EMBASE (via Ovid), CINAHL and Global Health (via EBSCO) and grey literature databases were searched up to 17 September 2022.

Eligibility criteria

We included primary qualitative, quantitative and mixed-methods studies reporting implementation or use of calcium supplements during pregnancy, excluding calcium fortification and non-primary studies. No restrictions were imposed on settings, language or publication date.

Data extraction and synthesis

Two independent reviewers extracted data and assessed risk of bias. We analysed the qualitative data using thematic synthesis, and quantitative findings were thematically mapped to qualitative findings. We then mapped the results to behavioural change frameworks to identify barriers and facilitators.

Results

Eighteen reports from nine studies were included in this review. Women reported barriers to consuming calcium supplements included limited knowledge about calcium supplements and pre-eclampsia, fears and experiences of side effects, varying preferences for tablets, dosing, working schedules, being away from home and taking other supplements. Receiving information regarding pre-eclampsia and safety of calcium supplement use from reliable sources, alternative dosing options, supplement reminders, early antenatal care, free supplements and support from families and communities were reported as facilitators. Healthcare providers felt that consistent messaging about benefits and risks of calcium, training, and ensuring adequate staffing and calcium supply is available would be able to help them in promoting calcium.

Conclusion

Relevant stakeholders should consider the identified barriers and facilitators when formulating interventions and policies on calcium supplement use. These review findings can inform implementation to ensure effective and equitable provision and scale-up of calcium interventions.

Objective

We aimed to identify all available studies describing measures or indicators used to monitor 41 intrapartum care practices described in the 2018 WHO intrapartum care recommendations, with a view to informing development of standardised measurement of implementing these recommendations.

Design

Systematic scoping review.

Methods

We conducted a scoping review to identify studies reporting measures of intrapartum care published between 1 January 2000 and 28 June 2021. Primary and secondary outcome measures included study characteristics (publication year, journal, country and World Bank classification) and intrapartum care measure characteristics (definition, numerator, denominator, measurement level and measurement approach). We searched MEDLINE, EMBASE, CINAHL, Cochrane Library, the Maternity and Infant Care Database, Global Index Medicus and grey literature using structured search terms related to included recommendations, focusing on respectful and supportive care, and clinical practices performed throughout labour and birth. The measures identified were classified by the WHO recommendation and their characteristics reported.

Results

We identified 150 studies which described 1331 intrapartum care measures. These measures corresponded to 35 of the 41 included WHO recommendations, and represented all domains of the WHO recommendations (care throughout labour and birth, first stage of labour, second stage of labour, third stage of labour). A total of 40.1% (534 of 1331 measures) of measures were related to respectful maternity care. Most studies used a questionnaire or survey measurement approach (522 of 1331 measures, 39.2%).

Conclusion

This scoping review presents a database of existing intrapartum care measures used to monitor the quality of intrapartum care globally. There is no clear consensus on a core set of measures for evaluating the practice of the WHO’s intrapartum care recommendations. This review provides a foundation to support the development of a core set of internationally standardised intrapartum care measures for the WHO intrapartum care recommendations, highlighting key areas requiring consensus and validation, and measure development.

A prospective study to analyse the concentration of octenidine in hand wounds after disinfection by LC–MS/MS

Abstract

Toxic reactions can appear after pressurised flushing of soft tissue with octenidine (OCT) containing disinfectants. Their use for surgical disinfection could complicate the diagnosis of possible contamination. In patients with open lacerations of their hand's subcutaneous tissue samples were taken before and after surgical disinfection with Octenisept® and analysed by ultra-high-performance liquid chromatography coupled to tandem mass spectrometry (LC–MS/MS). In 16 out of 20 tissue samples, OCT was detected after disinfection (lower limit of quantification (LLOQ)=10 pg/mL/mg). The concentration of OCT was below the LLOQ, estimation of mean of 0.6 pg/mL/mg (0.22–0.98 pg/mL/mg, 95%-CI) before disinfection and mean of 179.4 pg/mL/mg (13.35–432.0 pg/mL/mg, 95%-CI) after disinfection. This study shows that the disinfection of open wounds with Octenisept® leads to a quantifiable concentration of OCT in open wounds. In cases of suspected OCT-mediated toxic reaction, the use of antiseptics containing OCT should be avoided.

Missed nursing care in relation to registered nurses' level of education and self‐reported evidence‐based practice

Abstract

Background

Patient safety is one of the cornerstones of high-quality healthcare systems. Evidence-based practice is one way to improve patient safety from the nursing perspective. Another aspect of care that directly influences patient safety is missed nursing care. However, research on possible associations between evidence-based practice and missed nursing care is lacking.

Aim

The aim of this study was to examine associations between registered nurses' educational level, the capability beliefs and use of evidence-based practice, and missed nursing care.

Methods

This study had a cross-sectional design. A total of 228 registered nurses from adult inpatient wards at a university hospital participated. Data were collected with the MISSCARE Survey-Swedish version of Evidence-Based Practice Capabilities Beliefs Scale.

Results

Most missed nursing care was reported within the subscales Basic Care and Planning. Nurses holding a higher educational level and being low evidence-based practice users reported significantly more missed nursing care. They also scored significantly higher on the Evidence-based Practice Capabilities Beliefs Scale. The analyses showed a limited explanation of the variance of missed nursing care and revealed that being a high user of evidence-based practice indicated less reported missed nursing care, while a higher educational level meant more reported missed nursing care.

Linking evidence to action

Most missed nursing care was reported within the subscales Planning and Basic Care. Thus, nursing activities are deprioritized in comparison to medical activities. Nurses holding a higher education reported more missed nursing care, indicating that higher education entails deeper knowledge of the consequences when rationing nursing care. They also reported varied use of evidence-based practice, showing that higher education is not the only factor that matters. To decrease missed nursing care in clinical practice, and thereby increase the quality of care, educational level, use of evidence-based practice, and organizational factors must be considered.

Dimensions in women's experience of the perinatal period

A positive experience of the perinatal period is significant for women in midwifery care. The literature on women's experiences of the care in this period is extensive. However, a clear overview of the dimensions important for women's experiences is lacking. Consequently, care providers and researchers may ignore aspects significant to women's experience. In this short communication, we present a framework identifying the dimensions relevant for women's experiences of the perinatal period.
