Published: February 2025

The paper presents the results of gas dynamic calculation and strength analysis required to optimize the mathematical model of the body of the catalytic collector of a passenger car. Based on the obtained results of numerical modeling, the optimization of the case was performed. As a result of the gas-dynamic calculation, the optimal variant of the catalytic collector housing with the required uniformity of the exhaust gas flow in the input section of the catalyst (coefficient of unevenness (UI > 0.8)) was selected. According to the results of the strength analysis, stainless steel was selected to withstand emerging mechanical stresses at maximum temperatures up to 600 °C.
From ‘safe haven’ to ‘zone of precarity’: locating Istanbul through the perceptions and everyday urban practices of skilled migrants
Authors: Tuncer Ezgi
Published: February 2025

This article seeks to position Istanbul through the practices of everyday life of middle-class, skilled migrants from both the Global North and South and their perceptions of urban safety and precarity. It examines individuals’ processes of migration to Turkey, revealing their initial impressions of Istanbul as a safe city of opportunities, and then analyses their everyday urban lives, highlighting hidden forms of precarity and discrimination. Through in-depth interviews with 45 women and 34 men—more than half of whom are North American and European—and participant observation in people’s living environments and at various social events, I argue that Istanbul, while perceived as a ‘safe haven’ at first, becomes a ‘zone of precarity’ where most of the participants have experienced intersectional forms of precarity, latent patterns of discrimination, and insecurities that belie the common perception that skilled migrants are privileged. To substantiate this argument, this ethno-spatial study presents an analysis of qualitative data as well as an online subjective mapping of Istanbul, where perceptions of urban safety and spatial precarity are displayed through socio-spatial experiences encountered in neighbourhoods, workplaces, and public spaces.

Published: February 2025

Background

Pneumococcal pneumonia is a common disease with a significant impact on morbidity and mortality among the elderly population. The main purpose of this meta-analysis was to estimate the prevalence of community-acquired pneumonia (CAP) in elderly individuals caused by Streptococcus pneumoniae (S. pneumoniae).

Methods

A systematic search of the PubMed, Web of Science, and Scopus databases was conducted for relevant studies published between January 2013 and December 2023. Subgroup analysis and meta-regression were used to identify the sources of heterogeneity affecting the 87,430 patient studies obtained from 47 papers that met the inclusion and exclusion criteria.

Results

The combined prevalence rate for S. pneumoniae among all CAP patients included in the study was 14.8% (95% confidence interval [CI]: 12.3–17.8%). The 5-year pooled prevalence decreased from 16.5% (95% CI: 15.0–18.2%) in 1996–2000 to 8.4% (95% CI: 6.3–11.0%) in 2016–2020 for bacterial culture alone and from 17.4% (95% CI: 16.3–18.7%) to 13.5% (95% CI: 10.7–16.8%) for bacterial culture and urinary antigen testing (UAT) combined (P < 0.001). The most prevalent serotype was serotype 3, followed by serotypes 8, 19 A, 22 F, 11 A, 5, 9 N, 12 F, 6 A, and 10 A. The vaccine-serotype coverage was 53.5% for PCV 13, 60.5% for PCV 15, 85.2% for PCV 20 and 88.6% for PPSV 23.

Conclusion

These findings indicate a decrease in the overall burden of pneumococcal CAP among elderly individuals over the decade, which lends support to the proposition that the delivery of immunization should be expanded across the life course.

Published: February 2025

Background

The important roles of well-being as realization of one’s true potential for healthy aging have been highlighted by literature of the recent decades. The Scales of Psychological Well-being (SPWB) are an internationally recognized measurement tool for psychological well-being. Yet, sound validation of the German SPWB 18-item version has been lacking to date. Therefore, the present study aims to (1) test the psychometric properties of the German SPWB 18-item version in terms of factorial validity and (2) determine construct validity by investigating its correlations with psychosocial variables, mental and physical health. (3) Sociodemographic characteristics of the SPWB in a middle to old age German population was explored.

Methodology

Data of N = 3,374 participants 45–85 years old of the 10-year follow-up (2017–2022) of the Gutenberg Health Study (GHS) were analyzed. Descriptive analyses and inference statistical analyses were performed to assess construct validity. In order to determine the psychometric properties, item characteristics and reliability coefficients were analyzed. Confirmatory factor analyses tested the proposed theoretical factorial structure.

Results

Construct validity of the SPWB was established with respect to sociodemographic, psychosocial (social support and resilient coping), and health variables (sleeping problems, depression and anxiety symptoms, stress, loneliness, and somatic diseases). Analysis of the psychometric properties of the German SPWB 18-item version rendered support for the theoretically proposed multidimensional structure of psychological well-being in our sample rather than a one factorial structure. Bi-factor models that take the method effects of positively and negatively formulated items into account are highly recommended.

Conclusions

The German SPWB 18-item version shows comparable psychometric properties to previous large-scale studies from other countries. The SPWB provides psychological indicators for healthy aging.

Published: February 2025

The geographical location of Indonesia in the tropical region, characterized by high temperatures and humidity, is favorable for the development of viral diseases in rice. Climate change and intensive rice production systems further exacerbate the detrimental effects of viral diseases on rice sustainability. Three major rice virus diseases in Indonesia—rice tungro disease (RTD), rice rugged stunt virus (RRSV), and rice grassy stunt virus (RGSV)—have affected more than 170,000 ha of rice from 2010 to 2022. Key factors contributing to viral disease epidemics in the country include the extensive planting of high-yielding varieties twice a year, intensive use of fertilizers, asynchronized planting, and erratic climatic conditions. Cultivating rice varieties that are resistant to both viruses and their vector insects is the most effective and efficient strategy for the integrated pest management of rice viral diseases. The development of RTD-resistant rice varieties has been relatively successful in Indonesia, as demonstrated by the release and adoption of 18 resistant varieties. However, the development of RRSV and RGSV-resistant varieties remains challenging due to a lack of genetic resources for improving rice resistance. Progress has been achieved only by developing varieties resistant to brown planthoppers as vectors of these virus diseases. To address these challenges, the potential use of genetic technology to develop rice that is resistant to viral diseases is discussed.

Published: February 2025

Background

The present study aimed at investigating the effectiveness of zeinmersomes (ZMS)-based nano-formulation to enhance icariin (ICA) cytotoxicity in colon cancer cells. The prepared ICA-ZMS was characterized with respect to particle size, entrapment efficiency, and in vitro release.

Results

ICA-ZMS showed higher cytotoxicity in HCT-116 cells compared to HT-29 and Caco-2 cells with almost no cytotoxicity in normal HCoEpC colon cells. In this regard, ICA-ZMS exhibited potentiated cytotoxicity as compared to ICA-raw. In HCT-116 cells, ICA loaded on ZMS exhibited better cellular penetration compared to ICA-raw. The accumulation of HCT-116 in the S phase was identified using cell cycle analysis. Annexin V staining highlighted a potent pro-apoptotic activity of the prepared ICA-ZMS. This with confirmed by the observed up-regulated Bax and down-regulated Bcl-2 mRNA expression. Further, mRNA expression of p53, cytochrome C, and caspase-3 was significantly increased by exposing cells to ICA-ZMS. This was associated with a detectable decline in mitochondrial membrane potential. These data were confirmed by the ability of ICA-ZMS to significantly enhance the life span of Ehrlich ascites carcinoma-bearing mice.

Conclusion

This study suggests that the loading of ICA on ZMS nanoparticles enhances its cytotoxic and pro-apoptotic activities. This involves modulation of p53-dependent mitochondrial signaling.

Authors: Pham Minh T , Mahan John D , Shah Summit H , Estes Steven I , Kaler Stephen G
Published: February 2025

Progressive osseous heteroplasia (POH) is a rare autosomal-dominant hereditary bone disorder caused by inactivating pathogenic variants in GNAS1. POH is characterized by progressive cutaneous ossification and heterotopic ossification in skeletal muscles and subdermal connective tissues. Understanding of the natural history and phenotypic heterogeneity of the illness is incomplete. We report 2 affected male subjects with a milder than usual clinical course, highlight their clinical presentations and molecular correlates, and propose sodium 18F-fluorine positron emission tomography (PET) scanning as a sensitive technique for POH diagnosis and management.
Otto Huiswoud and the Demise of the Red Black Atlantic
Authors: Weiss Holger
Published: February 2025

This essay focuses on the activities of Otto Huiswoud from 1934 to 1937, when he was secretary of the International Trade Union Committee of Negro Workers (ITUCNW) and closely operated within the circuits of the Red International of Labour Unions and the Third (Communist) International. During these years, Otto Huiswoud and his wife, Hermina, tried to reinvigorate the ITUCNW and its network in the African Atlantic. After the introduction of the “popular front” tactics by the Comintern, Huiswoud proposed in October 1935 a thorough reorganization of the ITUCNW, although his plan remained a mere blueprint. Huiswoud’s activities came to an end when the Comintern liquidated the ITUCNW in July 1937.
Beyond Antagonism
Authors: James Leslie
Published: February 2025

This essay proposes a reappraisal of Otto and Hermina Huiswoud’s engagement with the Caribbean. The Huiswouds do not fit neatly in the stories of British Caribbean revolt of the 1930s, nor do they appear to be major figures shaping what was happening. They typically appear in tales of antagonism between two other major features of the decade: Garveyism and the Black Communist fellow travelers who departed the Comintern while they remained. Both instances of antagonism might instead be understood through what the author emphasizes are the intellectual points of convergence among overlapping—yet very distinctive—radicalisms. Via the Negro Worker, the organ of the International Trade Union Committee of Negro Workers, the Huiswouds participated in this intellectual ferment emanating from the Caribbean and crucially hooked into African continental and diasporic readings of colonial rule and economic exploitation.
Alternate Coda
Authors: Ménard Nadève
Published: February 2025

Régine Jean-Charles’s Looking for Other Worlds: Black Feminism and Haitian Fiction (2022) is part of a refreshing trend in Haitian studies of books that center a Haitian perspective. This review essay takes the liberty of offering reflections toward an alternate coda. What kind of texts are uniquely possible in the twenty-first century written by authors inspired by a tradition that includes feminist foremothers like Kettly Mars, Yanick Lahens, and Évelyne Trouillot? For as much as Looking for Other Worlds looks backward and horizontally, it does not really look forward. Jean-Charles enriches her readings by evoking earlier works like those by Poujol Oriol, highlighting the continuities between twentieth-century works by Haitian women and those produced by the authors of her corpus. The nonliterary cultural productions included by Jean-Charles—songs, paintings, photographs—are contemporary to the novels being analyzed and make an important point about these literary works being in conversation with pop music and visual arts. The author expected the book to end with a look forward into the work currently being created and published by younger women writers. It did not; this essay attempts to provide such a glimpse.

Published: February 2025

Background

The effectiveness of local treatment in lymph node metastasis from uterine cancer has been proven; the standard treatment is surgical intervention. Although radiotherapy, including particle radiotherapy (PRT), is an alternative local treatment, its application is often contraindicated owing to its proximity to the gastrointestinal tract. Combination treatment with spacer placement surgery followed by PRT is a potential solution to this problem. This study aimed to evaluate the outcomes of this combination treatment of lymph node metastases from uterine cancer.

Patients and Methods

Between December 2007 and March 2023, ten consecutive patients who underwent combination treatment comprising spacer placement surgery and subsequent PRT were assessed for treatment outcomes.

Results

The median survival time was 53.5 months; the 3- and 5-year overall survival rates were 76.2% and 38.1%, respectively. The 3- and 5-year local control rates in all patients were both 88.9%. The median volume irradiated at 95% of the treatment planning dose (V95%) of the gross tumor volume, clinical target volume, and planning target volume were 100.0%, 99.8%, and 92.2%, respectively. The median dose intensity covering 95% of the target volume (D95%) of the gross tumor volume/planned dose, clinical target volume/planned dose, and planning target volume/planned dose were 98.9%, 99.0%, and 87.2%, respectively.

Conclusions

Spacer placement surgery contributed to the optimized PRT dose distribution and might have contributed to favorable local control and survival rates. This innovative combination treatment might have a significant effect on the treatment of lymph node metastases from uterine cancers.

Published: February 2025

Introduction/Purpose

The oxygen uptake- (V̇O2) to-power output (PO) relationship from incremental exercise needs to be adjusted to accurately prescribe constant-intensity exercise training. We assessed accuracy of a “step-ramp-step” (SRS) protocol for prescribing constant-PO exercise within moderate- (below estimated lactate threshold, θLT), heavy- (between θLT and respiratory compensation point, RCP), and severe-intensity (above RCP) domains in fourteen patients with coronary artery disease (CAD).

Methods

The SRS protocol included in series: 6-min of cycling at 25-40 W, a ramp-incremental test until task failure (5-15 W·min−1), and, after recovery, 12-min of cycling at ~50-60% of peak ramp PO. On separate days, patients performed three domain-specific constant-PO exercises at 80%θLT (moderate-intensity, MOD), 70% of the difference between θLT and RCP (heavy-intensity, HVY), and 115%RCP (severe-intensity, SEV). Measured V̇O2 for: MOD and HVY were compared to those predicted using either SRS-corrected or uncorrected approaches; and, for SEV, were compared to peak ramp V̇O2.

Results

The POs for MOD, HVY, and SEV were 53 ± 27 W, 96 ± 50 W, and 116 ± 56 W, respectively, eliciting V̇O2 of 1012 ± 362 mL·min-1, 1541 ± 638 mL·min-1, and 1944 ± 744 mL·min-1. The SRS-corrected predictions did not differ from measured V̇O2 for MOD (-25 ± 61 mL·min-1; p = 0.201) or HVY (-40 ± 89 mL·min-1; p = 0.208), whereas uncorrected predictions underestimated V̇O2 by -128 ± 72 mL·min-1 (p = 0.002) and -199 ± 99 mL·min-1 (p = 0.001) in MOD and HVY, respectively. Peak V̇O2 from SEV did not differ from the ramp (1906 ± 766 mL·min-1; p = 0.759).

Conclusions

In CAD, the V̇O2-to-PO relationship from incremental exercise must be corrected to prescribe constant intensity training. The SRS protocol is an accurate approach to ensure prescriptive accuracy.
Microhomology-mediated end-joining Knock-In approaches to delete the allergenic domain of trout parvalbumin beta-1. Preliminary results in F0 animals and feedback
Authors: Lebret Veronique , Duret Cecile , Herpin Amaury , Rescan Pierre-yves
Published: February 2025

Background Gene editing techniques offer new opportunities to improve important traits in aquaculture. The allergenicity of fish flesh is a major problem in aquaculture. Parvalbumin (Parv) is the most prevalent fish allergen. For instance, in salmonids, a single parvalbumin beta-1 protein (parvb1) has been identified as an allergen in specific patients. Therefore, generating trout carrying two parvb1 alleles deleted from the allergenic peptide-encoding region could prevent allergies in these sensitive individuals. Methods Here, we describe the application of the Crispr/cas9 system in an attempt to delete parvb1 exon 2 encoding the allergenic peptide and, alternatively, to replace exon 2 of parvb1 with exon2 of parvalbumin beta-2 protein (parvb2,) which does not encode the allergenic peptide. Exon skipping and swapping were pursued through microhomology-mediated end-joining (MMEJ) knock-In using specifically designed double-stranded donor DNA. Results Genotyping of approximately 200 F0 fingerlings originating from eggs injected with donor DNA designed for exon 2 skipping led to the identification of only one animal carrying an allele lacking exon 2. Genotyping of approximately 150 fingerlings originating from eggs injected with donor DNA for exon 2 swapping did not result in any trout carrying the expected modified allele. Conclusions These preliminary results indicate the potential difficulties associated with the MMEJ KI experiments performed in farmed fish. Finally, new genomic techniques in aquaculture are further discussed in the context of lively debates taking place in the European parliament regarding a possible revision of the current law that determines the legal status of farm animals modified by genome editing.

Fiqh al-Awlawiyat is the basis for education on halal food and beverage
Authors: Abdurrahman Usamah , Ardiani Yana Elita , Sa'adah Yaumi
Published: February 2025

This study aims to elaborate on the conception of halal and its education in the contemporary context and explain how fiqh al-awlawiyat can be applied as a basis for halal education in food and beverage products. After explaining halal as Islamic ethics and morality at different levels, it is explained how fiqh al-awlawiyat is highly urgent in its operation. In the final section, by parsing several fiqh al-awlawiyat rules, four recommendations are given, namely: (1) qualitative indicators of halal achievements need to be proclaimed as a foundation for quantitative indicators that have so far been applied, (2) halal educators need to be equipped not only with practical knowledge about the administrative aspects of halal certification, but also more sophisticated scientific tools such as fiqh al-awlawiyat, fiqh al-waqi', fiqh al-maqasid, and so on, (3) in the education process, educators need to pay attention to the gradual process by directing business partners to take care of their compliance with halal values respectively starting from reciprocal ethics, tolerant ethics, and altruistic ethics based on their abilities, and (4) the education process should not end when halal certification has been obtained but continued so that it can reach a higher level.

Published: February 2025

Hair is one of the most essential parts of the human body, both men and women; one of the problems with hair that often occurs is hair loss. Chia plants contain sebum gland-stimulating agents with a keratin protein concentration of 23%. The sebaceous glands play a role in facilitating the growth of hair follicles so that hair can thrive and prevent hair loss. This research aims to determine the optimum composition of the prediction formula using Design Expert software and the physical characteristics and stability of liquid shampoo preparations. Optimization was carried out using Design Expert 13 software with two material components, namely HPMC and SLS, and two responses, namely viscosity and foam height. The optimum formula obtained was subjected to characteristic tests and stability tests. The stability test was carried out using the cycling test method by storing the preparation at temperatures of 4◦C and 40◦C for 48 hours. The results of the prediction formula show that component X1 is 0.589307% and X2 is 9.41069%. The one-sample t-test showed that the results were not significantly different at p>0.05 in the two responses. Testing of the optimum formula's physical characteristics and physical stability meets the reasonable requirements for organoleptic tests, homogeneity tests, viscosity tests 414,80±9,94 cPs, foam height tests 7,060±0,11 cm, and pH tests 7,39±0. The 8th run is the optimum formula with a composition of X1 0.589307% and X2 9.41069 % meets the requirements for good physical characteristics tests and physical stability tests.
O amor como uma performatividade de gênero: ambivalências em Anne com E
Authors: Feital Yasmine , Lucas Garcêz Regiane
Published: February 2025

Este artigo tem como objetivo investigar o amor no audiovisual a partir da proposta do gênero como performativo de Judith Butler (2021). Indaga-se como se configuram as diferentes formas de amor de acordo com diferentes performatividades de gênero. Para tal, foram analisadas três cenas da série Anne com E, da Netflix (2017-2020). A metodologia se baseia na articulação entre a análise fílmica feminista (Gomes Barbosa; Mendonça, 2021) e a análise da materialidade audiovisual (Coutinho e Mata, 2018). Os resultados indicam que há uma aposta da série em captar o amor e as performatividades de gênero em suas ambivalências, construindo suas narrativas românticas e relações afetivas a partir das limitações linguísticas e dos campos normativos de poder.

Pela produção de um contra-arquivo do imaginário de freiras lésbicas no cinema e na TV
Authors: De Almeida Ana Caroline
Published: February 2025

No gesto de inventariar como o audiovisual projeta o imaginário de freiras lésbicas, o artigo usa o filme Para sempre condenadas, de Su Friedrich, como uma linha de força para criação de um contra-arquivo que deseja rever, a partir de um olhar queer/cuir, o imaginário produzido sobre freiras lésbicas tanto em filmes, quanto em uma série de TV. A proposta é cruzar as imagens do filme de Friedrich com a de outras obras audiovisuais, bem como entrelaçar essas visualidades com depoimentos reais publicados em um livro chamado chama As freiras lésbicas: rompendo o silêncio, de 1985, transformando a escrita do inventário em uma escrita contaminada por memórias desejantes.

O uso da música como ferramenta de comunicação está intrinsicamente ligado à produção cultural de pessoas periféricas. Do samba ao Hip Hop, as comunicações populares carregam conteúdos específicos de seus grupos, incluindo o amor presente como expressão de união e resistência aos problemas sociais e silenciamentos enfrentados pela maior parte da população brasileira. Este trabalho tem como objetivo analisar a letra da música Capítulo 4, Versículo 3, a partir de levantamento bibliográfico e análise de conteúdo para selecionar e interpretar as informações existentes na letra e que são reveladoras das situações enfrentadas pelas pessoas periféricas e que também refletem o amor, a partir de bell hooks.

Há duas décadas celebramos o ‘descobrimento’ do Brasil. O quão distantes estamos, hoje, desta realidade? E o quão perto estamos de nos entender brasileiros? Com inspiração em trabalhos de artistas contemporâneos em diálogo com a teoria do caráter destrutivo de Walter Benjamin – onde faz-se destroços do existente menos pelas ruínas que pelos caminhos que surgem através delas (1973, p. 14) –; o presente artigo propõe pensarmos no que é preciso destruir da história oficial, uma história que ainda se pauta na invasão e colonização portuguesa, para abrir caminhos para uma nova história milenar, de resistência e de festa. Uma narrativa que devolva, por fim, o amor à história brasileira.
Não era amor, era cilada

Quando se fala em assédio sexual de rua, é comum a sua confusão com o flerte. Há também a dificuldade de se distinguir entre cordialidade e assédio no caso de cumprimentos ou pretensos elogios entre desconhecidos no espaço público. Diante dessas questões de sentido, este artigo se apoia na teoria semiótica das interações de E. Landowski (2014) para buscar compreender a diferença entre as interações pautadas no assédio e as interações amorosas. As análises mostram tipos de amor que correspondem aos regimes de acidente (amor à primeira vista), de manipulação (amor estratégico) e de ajustamento (amor confluente). Já o assédio parece constituir uma interação programada que, do ponto de vista do assediador, é baseada no papel temático determinado pela masculinidade hegemônica, não podendo ser confundida com o amor.

As novas narrativas do amor parental na contemporaneidade
Authors: Nassar de Oliveira Paulo Roberto , Mazzucatto Maria Rita
Published: February 2025

O presente artigo propõe-se discutir, sob a ótica da comunicação, em interface com o afeto, as novas narrativas da parentalidade contemporânea no Brasil. O estudo analisa 21 artigos sobre a temática do amor parental, escritos por Iaconelli no veículo de comunicação e publicados entre os anos 2020 e 2021. Para isso, fizemos uma breve contextualização sobre os conceitos de amor na filosofia, relacionamos as características da contemporaneidade com os atuais desafios das relações sociais, sobretudo o amor parental, e pudemos, então, partir para a visão da psicanalista Vera Iaconelli sobre o tema em sua coluna semanal na Folha de S. Paulo, depreendendo disso possíveis novas narrativas sobre o amor parental. A discussão foi possível a partir da técnica de análise de conteúdo e algumas de nossas conclusões recaem sobre o fato de que vemos as novas configurações afetivas demandarem mais igualdade de direitos entre pais e mães e exigirem a validação de novos arranjos familiares, relacionados à promoção de uma sociedade mais justa, diversa, inclusiva e solidária.
COMO CRIAR FILHOS GAYS:

O menino afeminado, que optamos por chamar de “criança viada”, éo cupim das arquiteturas normatizantes de gênero e sexualidade. Não porescolha, mas por imposição. “Quem defende a criança queer?” perguntou-nos,posteriormente, Paul Preciado. Poucas pessoas. O que Sedgwick provocavaé que, mesmo para adultos gays bem resolvidos, o trauma e a assombraçãoque vivenciamos nos faziam repelir e nos afastar de qualquer discussão queexigisse posicionamento diante da criança viada que fomos.

Published: February 2025

O presente tem por objetivo analisar e descrever os efeitos dos diferentes valores utilizados no parâmetro “skip distance” (s), sem mudança nas demais variáveis, para geração dos elementos de relevo (geomorphons) de forma semiautomatizada na Bacia Hidrográfica do Areal do Paredão (BHAP), Oeste do estado do Rio Grande do Sul. Utilizou-se MDE com resolução espacial de 30 metros, e o raio de busca (L) utilizado foi de 20 pixels. O skip distance (s) é o parâmetro testado no trabalho, neste foram efetuados processamentos com 0, 3, 5, 10 e 15 pixels. Observou-se que para a área em questão, a mudança do parâmetro skip distance (s) ocasiona em resultados com significativas diferenças, principalmente na representação de pequenas feições. Através disso, destaca-se que o valor do parâmetro “s” pode variar, o que é definido a partir das características e singularidades presentes na área de estudo, o que torna importante a prévia comparação com diferentes valores. O que torna necessário conciliar a escolha do valor ideal para o parâmetro através da análise entre MDE e a representação das características e fenômenos que se associam em toda a paisagem.

Published: February 2025

Grounding, the practice of direct contact with the Earth’s surface, has been explored for its potential to alleviate inflammation and neurotoxicity. Trimethyltin (TMT) is a potent neurotoxic compound known for inducing severe central nervous system damage, particularly neuronal death and neuroinflammation in the hippocampus, which is frequently used as an animal model to study neurodegenerative disorders, such as Alzheimer disease, due to its ability to induce oxidative stress, inflammatory responses, and neurodegeneration. This study investigated the effect of a grounding mat on cognitive function, neuroinflammation, and neuroprotection in a TMT-induced neurotoxicity rats. Rats were divided into five groups: no grounding mat with saline (Nor), no grounding mat with TMT (Con), electric mat for 21 days with TMT (EM), grounding mat for 7 days with TMT (A-7D), and grounding mat for 21 days with TMT (A-21D). Cognitive function was assessed via the Y-maze test, while blood levels of interleukin (IL)-1β, IL-4, prostaglandin E2 (PGE2), and hippocampal acetylcholinesterase (AChE) were measured by enzyme-linked immunosorbent assay. The Con group showed impaired memory and elevated IL-1β and PGE2 levels, alongside reduced IL-4, compared to the Nor group. The A-7D group improved memory performance, and the A-21D group showed reductions in IL-1β and P PGE2, with increased IL-4 levels. Both A-7D and A-21D groups had elevated AChE levels compared to the Con group. These findings suggest that grounding may enhance cognitive function by reducing inflammation and promoting neuroprotection in a neurotoxicity model.

Published: February 2025

Background/Aims

Stress can lead to low work satisfaction and increased burnout, sickness/absence and staff turnover. A midwifery clinical supervision service was developed by two senior clinical psychologists and piloted. It aimed to offer clinical supervision and staff support to specialist groups of midwives.

Methods

Questionnaires were completed by 47 staff who attended the pilot service, assessing their experiences and psychological outcome measures at the first and last sessions. Paired sample two‑tailed t‑tests were used to test for differences between baseline and follow‑up scores for wellbeing measures. Thematic analysis was used for qualitative data.

Results

Overall satisfaction was high, and attending multiple sessions significantly improved overall emotional wellbeing. Burnout was significantly lower, and there was a reduction in traumatic stress symptoms and improved rates of compassionate satisfaction.

Conclusions

Midwives and staff in maternity services value and benefit significantly from psychological support and specialist clinical supervision.

Implications for practice

Clinical supervision and staff support models should be provided in maternity services. This will directly impact the quality of care that staff provide.
Maternal perception of pregnancy loss: a qualitative systematic review
Authors: Freitas Conceição Moreira , Magalhães Bruno , Martinez-Galiano Juan Miguel
Published: February 2025

Background/Aims

Pregnancy loss is a complex and often stigmatised event with a significant impact on mothers. Understanding maternal perception is crucial for personalised care, but research on this is fragmented. This review synthesises qualitative studies on mothers' perceptions of pregnancy loss.

Methods

A systematic review with thematic synthesis was conducted across five databases (Medline, CINAHL, Psychology and Behavioural Sciences Collection, Scopus, Cochrane). Qualitative studies published between January 2012 and March 2024 were included.

Results

A total of 15 studies were selected. Five themes emerged: facilitators, inhibitors, context, professional support and impact.

Conclusions

Pregnancy loss deeply affects women's personal and professional lives, with perceptions shaped by support from family, healthcare professionals, and cultural or religious factors.

Implications for practice

Reforming hospital care and increasing emotional support for mothers and healthcare providers are critical. Further research should explore this topic to inform specific training and care strategies.
The Impact of COVID-19 on UK Medical Students’ Perceptions of Cardiothoracic Surgery—A Comparison of Nationwide Surveys in 2018 and 2022
Authors: Gnanalingham Sathyan , Gnanalingham Raman , Limbachia Devan
Published: February 2025

Aims/Background The effects of the coronavirus disease 2019 (COVID-19) pandemic on surgical specialities have been devastating, with more than 1.5 million operations cancelled in 2020, leading to reduced training opportunities and morale. We investigated the impact of COVID-19 pandemic on UK medical students’ interest in pursuing a career in cardiothoracic surgery (CTS) and their perceptions of the field, including perceived challenges and opportunities.

Methods This study is a comparative cross-sectional study design aiming to assess if there were changes in perceptions amongst UK medical students before and after COVID-19. We distributed the same online survey to all UK medical schools via social media outlets before COVID-19 in 2018 and after in 2022. The Chi-square test was used to analyze differences, with a significance level set a p < 0.05.

Results Overall, career intentions of survey respondents towards CTS did not change between 2018 and 2022. However, students’ perceptions towards CTS became more negative (p = 0.033). In 2018, for instance, 37% of survey respondents had neutral or negative perceptions of CTS which increased to 59% in 2022. This result was statistically significant, indicating the negative impact of COVID-19 on UK medical students’ perceptions of CTS.

Conclusion Overall, the effects of COVID-19 did not have a significant impact on medical student interest in a career in CTS. However, negative perceptions associated with a career in CTS persist. A new era of remote, hybrid career events and student modules in CTS could encourage greater interest.

Health visitors' psychological and emotional responses to service change
Authors: Seaman Helen Elizabeth
Published: February 2025

A qualitative study was carried out to investigate how service changes implemented by one NHS Trust in England affected health visitors' professional identity. Twenty health visitors were interviewed over 22 months. Commencing in 2018, and including the initial peak of COVID-19 pandemic, the study used Interpretative Phenomenological Analysis (IPA) combined with an art-based approach. A comprehensive professional identity for health visitors was established, as discussed in a previous article ( Seaman, 2022 ). A second article ( Seaman, 2023 ) outlined the effects of service changes as described by the participants. These were mapped onto the core dimensions of their perceived professional identity and recommendations for health visitor managers, employers, policy, and decision-makers offered. This final follow-up article charts the participants' psychological and emotional responses to the service changes. Further recommendations are included relating specifically to the psychological needs and mental wellbeing of practising health visitors. Change is perpetual, not least in the NHS. For this reason, the research findings documenting the psychological effects of change on health visitors, and associated recommendations, continue to be relevant and worthy of consideration.
