ABSTRACTIntroductionAlthough the benefits of doula care during childbirth are well‐known, its impact on childbirth‐related post‐traumatic stress disorder (CB‐PTSD) symptoms are less thoroughly characterized. This study aimed to explore the association between doula care and CB‐PTSD symptoms and the potential mediating role of childbirth experience on this association.MethodsA prospective cohort study was conducted in a hospital in China, enrolling women with singleton live vaginal births. The exposure and primary outcome factors of interest were doula care and CB‐PTSD symptoms, with childbirth experience as a mediating factor. Questionnaires were administered to collect baseline data and childbirth experience at 3 days postpartum, and CB‐PTSD symptoms from participants at 42 days postpartum. Linear regression analysis was used to analyze the relationship between doula care, childbirth experience, and CB‐PTSD symptoms, while the mediating role of childbirth experience was analyzed using the SPSS (PROCESS) modeling tool.ResultsA total of 445 eligible women were included in the final analysis, including 120 who received doula care and 325 who did not. Linear regression analyses found that doula care was independently associated with CB‐PTSD symptoms (β = −0.11, p < 0.05) and childbirth experience (β = 0.50, p < 0.001). Childbirth experience was significantly associated with CB‐PTSD symptoms (β = −0.17, p < 0.001). Childbirth experience mediated the association between doula care and CB‐PTSD symptoms (indirect effect = −1.08, 95% CI −1.91 to −0.10), even after adjusting for potential confounders.ConclusionsChildbirth experience serves as a mediator of the association between doula care and CB‐PTSD symptoms. By providing supportive care for women during childbirth, their childbirth experience could be improved, thereby reducing the risk of CB‐PTSD symptoms.
To pool or not to pool: Pooled metabarcoding does not affect estimates of prey diversity in spider gut content analysis

Abstract
Gut content metabarcoding has provided important insights into the food web ecology of spiders, the most dominant terrestrial arthropod predators. In small invertebrates, like spiders, gut content analysis is often performed on whole body DNA extracts of individual predators, from which prey sequences are selectively enriched and sequenced.
Since many spider species are generalist predators, large numbers of samples comprising individual spider specimens must be analysed to recover an exhaustive image of a spider species' prey spectrum, which is costly and time‐consuming.
Pooled processing of bulk samples of multiple specimens has been suggested to reduce the necessary workload and cost while still recovering a representative estimate of the prey diversity. However, it is still unclear if pooling approaches lead to bias in recovering the prey spectrum and if the results are comparable with data from individually processed spiders.
Here, we test the effects of metabarcoding pooled spider gut content on the recovered taxonomic diversity and composition of prey. Using a newly adapted primer pair, which efficiently enriches COI barcode sequences of diverse arthropod prey groups while suppressing spider amplification, we test if pooling leads to reduced taxonomic diversity or skewed estimates of prey composition.
Our results show that pooling and individual processing recover highly correlated taxonomic diversity and composition of prey. The only exception are very rare prey items which were less well recovered by pooling. Our results support pooling as a cost‐effective and time‐efficient approach to recover the diet of generalist predators for population‐level studies of spider trophic interactions.
Alternative double strand break repair pathways shape the evolution of high recombination in the honey bee, Apis mellifera

AbstractSocial insects, particularly honey bees, have exceptionally high genomic frequencies of genetic recombination. This phenomenon and underlying mechanisms are poorly understood. To characterise the patterns of crossovers and gene conversion in the honey bee genome, a recombination map of 187 honey bee brothers was generated by whole‐genome resequencing. Recombination events were heterogeneously distributed without many true hotspots. The tract lengths between phase shifts were bimodally distributed, indicating distinct crossover and gene conversion events. While crossovers predominantly occurred in G/C‐rich regions and seemed to cause G/C enrichment, the gene conversions were found predominantly in A/T‐rich regions. The nucleotide composition of sequences involved in gene conversions that were associated with or distant from crossovers corresponded to the differences between crossovers and gene conversions. These combined results suggest two types of DNA double‐strand break repair during honey bee meiosis: non‐canonical homologous recombination, leading to gene conversion and A/T enrichment of the genome, and the canonical homologous recombination based on completed double Holliday Junctions, which can result in gene conversion or crossover and is associated with G/C bias. This G/C bias may be selected for to balance the A/T‐rich base composition of eusocial hymenopteran genomes. The lack of evidence for a preference of the canonical homologous recombination for double‐strand break repair suggests that the high genomic recombination rate of honey bees is mainly the consequence of a high rate of double‐strand breaks, which could in turn result from the life history of honey bees and their A/T‐rich genome.

Published: September 2024

AbstractIncorporating specific defects into complex oxides facilitates the exploration of exotic phenomena and novel functionalities based on the intricate coupling between the defects and lattice/charge. However, methods for maximizing the density of specific defects while enhancing the desired properties have been rarely explored. In this study, the effect of N+ ion bombardment‐driven specific defects on the properties of bismuth ferrite (BFO) thin films was investigated. Furthermore, atomic structure characterization and computational processing revealed the displacement and orientation of the Fe atoms, which are linearly related to the degree of polarization. The ion bombardment introduced deep‐level trap states within the lattice, leading to a significant reduction in the leakage current and improved insulation performance of the films. By precisely engineering the defect content through N+ ion bombardment, the pure BFO thin films with remarkable and stable ferroelectric properties (remnant polarization, Pr = ∼116.8 µC·cm−2; leakage current, J = ∼1.5 × 10−8 A·cm−2) were fabricated. This innovative defect engineering‐based approach enables the customization and optimization of local ferroelectric order parameters, thereby establishing a solid foundation for designing functionalities across various functional material systems.

AbstractThe study aimed to provide validity evidence and reliability of the Scale of Myths of Romantic Love (SMRL) in Peru among young and adult individuals. Focusing on how romantic love myths affect relationship satisfaction and their ties to interpersonal violence, sexism, and gender inequality, the methodology involved 308 participants, mainly females (75%), using the SMRL and Relationship Assessment Scale. Bayesian Confirmatory Factor Analysis (BCFA) assessed the scale's structure and reliability, complemented by descriptive statistics and correlation analyses to examine the myths' impact on intimate relationships. Results showed the SMRL's two‐dimensional structure, confirming its robust psychometric properties and satisfactory internal consistency. Descriptive findings revealed a skeptical view of traditional romantic myths among participants, indicating the scale's good reliability and successful adaptation to the Peruvian context. This validation highlights how debunking romantic love myths can improve relationship dynamics and satisfaction and addresses their wider societal effects.

Published: September 2024

AbstractThe role of nurses in leading the design and delivery of primary health care services to address health inequities is growing in prominence, specifically in rural Australia. However, limited evidence exists to inform nurse‐led primary health care in this context. Based on a focus group with nursing executives and semi‐structured interviews with registered nurses we describe nurse experiences of leading the design of a primary health care service in rural Australia and nurse transition to and practice in this service. Nurse experiences were analysed using reflexive thematic analysis. The study reveals the centrality of relational integration in service design and nurse acquisition of relational practice as it relates to nurse to care recipient and nurse to nurse relationships. Tensions between primary health care nurses and their peers, and resultant de‐valuing of primary health care practice, are described. The acquisition of nurse professional agency draws attention to investments required to position nurses to lead and sustain care innovations external to hospital settings. The authors propose that relational approaches may provide nurses with the opportunity to reframe their leadership and service contributions towards community literate primary health care provision and provide a pathway to professional emancipation from constrained practice expectations.
Online political adverts: The effect of disclosures and opportunities for clandestine campaigning

Published: September 2024

AbstractThe use of digital technology has become an increasingly prominent feature of election campaigns. While many of those using online tools are familiar partisan actors, many others are not. As concerns about electoral transparency have grown, policy makers have moved to implement regulation designed to help citizens recognize the identity of campaigners. In this paper, we test the rationale behind such regulations by asking how disclosures on online adverts—both informal badging and formal imprints—affect evaluation by UK voters. Using experimental survey design, we test the reactions of participants to real Facebook adverts, labeled as originating from both partisan and apparently non‐partisan sources. Across three experiments, we consistently find evidence to support concerns about what we term “clandestine campaigning”; a phenomenon whereby apparently non‐partisan groups can receive a more favorable reception for incongruous partisan advert content than overtly incongruous partisan‐badged campaign material.

AbstractBackgroundGestational age significantly influences children's growth and development. Yet, the effect of postterm birth (gestation beyond 42 weeks) on children's growth outcomes remains underexplored.ObjectivesThis study aimed to assess the impact of postterm birth on adverse growth outcomes in children using a nationally representative sample from China.MethodsA retrospective cohort study was conducted in China from 1 April 2018, to 31 December 2019. The final analysis included 141,002 children aged 3–6 years from 551 cities. Postterm birth was defined as children with postterm birth at a gestational age of 42 weeks or more. Obesity, overweight and thinness were assessed using body mass index‐for‐age (BMI‐for‐age) z‐scores, based on the World Health Organization (WHO) Child Growth Standards. Generalised additive models were employed to investigate the non‐linear relationship between maternal gestational age and BMI‐for‐age z scores. Poisson regression models and subgroup analyses with forest plots were performed to examine the associations between postterm birth and the risks of obesity, overweight and thinness in children.ResultsWe included 141,002 mother–child pairs, of whom 7314 (5.2%) children were classified as postterm births. There exists a non‐linear relationship between gestational age and BMI‐for‐age z scores. Children born postterm exhibited a 46% increased risk of obesity, a 27% increased risk of combined overweight/obesity and a 13% increased risk of thinness. Similar associations were observed in most cases when further sensitivity and subgroup analysis were conducted.ConclusionsPostterm birth was associated with elevated risks of obesity, overweight and thinness in children aged 3–6 years, independent of sex. These findings underscore the importance of further research across diverse populations to understand the implications of postterm births on child health outcomes.

Published: September 2024

AbstractBackgroundAllogeneic hematopoietic cell transplantation remains limited when stem cell registrants cannot be contacted, are not medically fit, are unavailable, or unwilling to proceed. In a recent report, registrants who were prior blood donors were more likely to be available for donation. In this study, we analyzed extent to which recruiting blood donors to the Canadian Blood Services Stem Cell Registry (CBS SCR) can meet targets for ethnic diversity, age, and proximity to collection facilities.Methods and ResultsWe analyzed 124,496 active blood donors on July 1, 2023 regarding the criteria for recruitment to the CBS SCR. A total of 40,518 (32%) were younger than 36 years of age and 49% were first‐time donors (potential new recruits year over year). The ethnicity of blood donors younger than 36 years aligns more closely with the 2021 Canadian census compared to stem cell donors who were also previous blood donors, and to the current total inventory of all registrants on the CBS SCR. Of the blood donors, certain ethnic groups, including Black, Chinese, and First Nations/Indigenous, remain underrepresented. A greater proportion of active whole blood donors live within 400 km of a stem cell collection center (91%) compared to stem cell donors who donated during the past 10 years (80%).ConclusionsRecruitment of blood donors offers an opportunity to improve the ethnic diversity of the CBS SCR and increase proximity of registrants to stem cell collection centers. The potential improved availability of registrants when matched to patients requires confirmation.
Immune biomarkers and secondary hemophagocytic lymphohistiocytosis: a scoping review protocol
Authors: Terrett Alice , Van Loo Magalie , Sundararajan Krishnaswamy , Brealey David , Singer Mervyn , Manson Jessica , Raith Eamon Patrick 
Published: September 2024

Objective:
The objective of this review is to identify immunological pathways and markers of severity of illness associated with clinical outcomes that may represent potential therapeutic targets in the management of secondary hemophagocytic lymphohistiocytosis.

Introduction:
A broad range of immunomodulatory therapies is used to manage hemophagocytic lymphohistiocytosis, however, the supporting evidence for these therapies is scarce. Identifying patients likely to experience more severe disease or die is currently extremely difficult, if not impossible. The identification of implicated cytokines in secondary disease can provide further support for the identification of high-risk patients and the development of targeted therapies.

Inclusion criteria:
Studies reporting immune biomarker and cytokine measurement in adult patients (age ≥18 years) with secondary hemophagocytic lymphohistiocytosis will be considered for inclusion.

Methods:
The proposed review will be conducted in line with the JBI methodology for scoping reviews. MEDLINE (Ovid) and Embase (Ovid) will be searched, without date limitations. Data will be extracted using a data extraction tool developed by the reviewers. Relevant sources will be retrieved, and their citation details imported into the JBI System for the Unified Management, Assessment and Review of Information.

An Experimental Study on the Effect of Intake Pressure on a Natural Gas-Diesel Dual-Fuel Engine
Authors: Dev Shouvik , Guo Hongsheng , Liko Brian , Yousefi Amin 
Published: September 2024

Abstract
Natural gas-diesel dual-fuel (NDDF) combustion can be a viable method to reduce diesel usage in compression ignition (CI) internal combustion engines. Potential benefits of NDDF engines in comparison to conventional diesel engines include decreases in particulate matter (PM) and carbon dioxide (CO2) emissions. This study focuses on the effect of intake pressure on a dual-fuel engine with intake port injected natural gas (NG) and in-cylinder direct injected diesel at two typical engine operation conditions—low load-high speed and high load-low speed. The research work was performed on a heavy-duty, four-stroke CI, single-cylinder research engine at a NG-diesel energy ratio of approximately 3:1. The results show that when the intake pressure was increased, the indicated thermal efficiency (ITE) decreased and increased at the low load-high speed and high load-low speed conditions, respectively, for NDDF combustion. For the low load-high speed NDDF combustion, increasing intake pressure increased the carbon monoxide, methane, and soot emissions, but decreased the nitrogen oxide (NOx) emissions. For the high load-low speed NDDF combustion, increasing intake pressure caused the methane emissions to increase, and the carbon monoxide, NOx, and soot emissions to decrease. In-cylinder temperature measured at the tip of the diesel injector showed that the injector tip temperatures were higher for NDDF cases compared to diesel cases and these temperatures could be correlated with the combustion phasing and the NOx emissions. Increasing intake pressure caused lower injector tip temperatures for both NDDF operating conditions. Equivalent CO2 emissions for the low load-high speed and high load-low speed NDDF cases were higher and lower than the corresponding diesel cases, respectively.

ABSTRACT

The number of
Vibrio
-related infections in humans, e.g., by
Vibrio vulnificus
, has increased along the coasts of the Baltic Sea. Due to climate change, vibriosis risk is expected to increase. It is, therefore, pertinent to design a strategy for mitigation of the vibriosis threat in the Baltic Sea area, but a prerequisite is to identify the environmental conditions promoting the occurrence of pathogenic
Vibrio
spp., like
V. vulnificus
. To address this, we sampled three coastal Baltic sites in Finland, Germany, and Denmark with salinities between 6 and 21 from May to October 2022. The absolute and relative abundances of
Vibrio
spp. and
V. vulnificus
in water were compared to environmental conditions, including the presence of the eelgrass
Zostera marina
, which has been suggested to reduce pathogenic
Vibrio
species abundance. In the water column,
V. vulnificus
only occurred at the German station between July and August at salinity 8.1–11.2. Temperature and phosphate (PO
4
3–
) were identified as the most influencing factors for
Vibrio
spp. and
V. vulnificus
. The accumulation of
Vibrio
spp. in the sediment and the co-occurrence with sediment bacteria in the water column indicate that sediment resuspension contributed to
V. vulnificus
abundance. Interestingly,
V. vulnificus
co-occurred with specific cyanobacteria taxa, as well as specific bacteria associated with cyanobacteria. Although we found no reduction in
Vibrio
spp. or
V. vulnificus
associated with eelgrass beds, our study underscores the importance of extended heatwaves and sediment resuspension, which may elevate the availability of PO
4
3–
, for
Vibrio
species levels at intermediate salinities in the Baltic Sea.

IMPORTANCE

Elevated sea surface temperatures are increasing the prevalence of pathogenic
Vibrio
at higher latitudes. The recent increase in
Vibrio
-related wound infections and deaths along the Baltic coasts is, therefore, of serious health concern. We used culture-independent data generated from three Baltic coastal sites in Denmark, Germany, and Finland from May to October (2022), with a special focus on
Vibrio vulnificus
, and combined it with environmental data. Our temporal model shows that temperature, combined with sediment resuspension, drives the prevalence of
V. vulnificus
at intermediate salinities in the coastal Baltic Sea.
