Marine parasites remain understudied in South Africa with little information available on their diversity and the effects these parasites may have on their hosts. This is especially true for parasitic copepods within the family Ergasilidae. Among the 4 genera known in Africa, Nordmann, 1832 is the most speciose with 19 reported species.

The under-involvement of adolescents in health research has been attributed to multiple barriers faced by both researchers and adolescents. Despite identifying these barriers, the literature offers few solutions, mostly from the perspective of researchers. To address this, we conducted a qualitative study to explore effective strategies to address these barriers from the perspective of both researchers and adolescents.

Background: Refugees' parenting behaviour is profoundly influenced by their mental health, which is, in turn, influenced by their situation of displacement. Our research presents the first systematic review on parenting and mental health in protracted refugee situations, where 78% of all refugees reside.

Methods: We pre-registered our protocol and screened documents in 22 languages from 10 electronic databases, reports by 16 international humanitarian organisations and region-specific content from the top 100 websites for each of the 72 countries that 'host' protracted refugees.

Twenty-one specimens of an ergasilid were collected from the gills of the sharptooth catfish, Clarias gariepinus (Burchell), from the Eastern Cape, South Africa. The first leg and antennae morphology conformed to the genus Neoergasilus Yin, 1956. While the invasive Neoergasilus japonicus (Harada, 1930) is the only Neoergasilus species that has been reported from Africa, the combination of several characteristics, separates the Eastern Cape specimens from N.

Introduction: Creative art therapy (CAT) has become increasingly popular as a means of promoting positive mental health among adolescent refugees when accompanied by interdisciplinary interventions that engage families and communities. In this pre-registered systematic review (PROSPERO: CRD42022372538), we evaluated and synthesized the available literature reporting the use of CAT as a diagnostic, treatment and mental health promotion intervention with adolescent refugees, aged 10-24 years.

Methodology: We conducted a systematic search of the grey and black literature published in English and Arabic between 2012 to 2022 on 10 databases.

Background: Less than 1% of studies on child and adolescent health report the involvement of adolescents in health research. This is attributed to barriers experienced by researchers and adolescents in the engagement process. To address this under-involvement of adolescents, we first need a better understanding of the factors that hinder adolescent involvement in health research.

Although socioeconomic disadvantage is linked with academic underachievement, many children from low-income backgrounds perform well in school. Which modifiable factors predict this academic resilience? We examine between- and within-person predictors of one important academic metric - mathematics performance - across adolescence in 1715 (796 male, 919 female) youth living in poverty in Ireland, using data from three waves (9, 13, and 17/18 years) of the Growing Up in Ireland study. Using linear mixed models, math performance was worse when adolescents had more socioemotional and behavioural difficulties, more child-parent relationship conflict, parents had lower expectations of the adolescent's educational achievement, and when primary caregivers had less education.

Background: Meaningful involvement of adolescents in health research is their fundamental human right and has many benefits. A lack of awareness among researchers on how to meaningfully involve adolescents in health research has been linked to adolescent under involvement in health research. To address this barrier, studies have reported the need for more guidance.

Introduction: Despite high prevalence of anxiety among pregnant women in low- and -middle-income countries, research on context-specific conceptualisation, measurement, and predictors of pregnancy-related anxiety (PrA) is limited in these contexts. We explored local conceptualisations of factors influencing PrA in the Northern Region of Ghana.

Methods: We conducted 15 focus group discussions with antenatal care seekers in the Mion District, Savelugu Municipality, and Tamale Metropolis of the Northern Region, in July and August 2021.

Despite an increased recognition of the right of adolescents to be involved in decisions that affect them, young people continue to be under-involved in health research. One of the reasons is a lack of awareness among researchers on the current evidence base around the benefits of involving adolescents. To address this, we conducted an umbrella review to synthesize the evidence on the positive impacts of adolescent involvement in health research.

Systematic reviews are vital for guiding practice, research and policy, although they are often slow and labour-intensive. Large language models (LLMs) could speed up and automate systematic reviews, but their performance in such tasks has yet to be comprehensively evaluated against humans, and no study has tested Generative Pre-Trained Transformer (GPT)-4, the biggest LLM so far. This pre-registered study uses a "human-out-of-the-loop" approach to evaluate GPT-4's capability in title/abstract screening, full-text review and data extraction across various literature types and languages.

Refugee children's development may be affected by their parents' war-related trauma exposure and psychopathology symptoms across a range of cognitive and affective domains, but the processes involved in this transmission are poorly understood. Here, we investigated the impact of refugee mothers' trauma exposure and mental health on their children's mental health and attention biases to emotional expressions. In our sample of 324 Syrian refugee mother-child dyads living in Jordan (children's M=6.

Background: Refugee children are at high risk of mental health problems but face barriers to accessing mental health services, a problem exacerbated by a shortage of mental health professionals. Having trained lay counsellors deliver therapy via telephone could overcome these barriers. This is the first study to explore feasibility and acceptability of telephone-delivered therapy with refugee children in a humanitarian setting.

Research on coparenting is virtually absent from the refugee literature, despite its importance for family systems, children's bio-behavioural and emotional development, and intergenerational responses to social change. In 2022, we conducted 30 semi-structured interviews with Syrian refugees in Jordan and used thematic analysis to examine how fathers and mothers (n = 15 dyads) enacted parenting together. We identified four approaches characterising how couples navigated coparenting interactions, family cohesion, and intergenerational change.

Over 36 million children are currently displaced due to war, yet we know little about how these experiences of war and displacement affect their socioemotional development-notably how they perceive facial expressions. Across three different experiments, we investigated the effects of war trauma exposure on facial emotion recognition in Syrian refugee ( = 130, = 9.3 years, 63 female) and Jordanian nonrefugee children ( = 148, = 9.

The preservation of the world's biodiversity for future generations has been a global objective for many years, with the establishment of the International Union for Conservation of Nature (IUCN) Red List of Threatened Species in 1964. However, the conservation of parasites is a more recent development and, due to the difficulty in obtaining data and studying some of the parasitic species, comes its own series of challenges. Using parasites of cyprinid hosts (one critically endangered, one endangered and three near threatened) collected from South Africa's Cape Fold freshwater ecoregion (CF) as a case study, this paper discusses the challenges and possible solutions for implementing a fish parasite conservation project.

The instability hypothesis proposes that family structure transitions lead to negative child outcomes through the pathway of stress. However, in many cases, family structure transitions are not associated with stress or negative child outcomes, suggesting that there are specific circumstances under which transitions are more or less stressful. Using five rounds of data (ages 1-15) from the Young Lives study ( = 8,062) which follows children and their caregivers in Ethiopia, India, Peru, and Vietnam, we had two aims: (a) to test the instability hypothesis, and (b) to examine the specific circumstances under which family structure transitions lead to stress and worsened child physical health.
