TEM analyses of germinal elements in miracidia and 6-day-old mother sporocysts of Echinostoma caproni were performed. Germinal elements in miracidia are represented by undifferentiated cells and germinal cells. They are localised in the posterior half of the body and form the primordium of the germinal mass, which plays the role of the gonad. In mother sporocysts the germinal mass is located caudally and plays the dual role of the gonad and the uterus. In addition to the undifferentiated cells and germinal cells, it contains embryos, which develop there up to the stage of germinal balls and then move into the sporocyst’s schizocoel, which plays the role of the brood chamber. New germinal cells are formed only by division of undifferentiated cells. No differences between undifferentiated and germinal cells in miracidia and those in sporocysts were found.

UK food system transformation is urgently needed, but to date, minimal research has investigated ‘blue foods’ probably because they are ethically nuanced. There exists a paradox whereby materially deprived communities should be eating more fish to meet nutritional requirements, yet there is a global ‘red flag’ around global overfishing. New collaborative and creative solutions are, therefore, needed to tackle such food system inequities. By working together, all voices can be equally heard when decisions are being made to improve the system. Similarly, innovation and disruption of established supply chains will enable better access to healthy, affordable and tasty food that will support better nutrition, health and wellbeing. This review paper will present a critique of the ‘The Plymouth Fish Finger’ as a collaborative social innovation case study. Part of the FoodSEqual research project, this exploratory pilot project championed ‘co-production’ approaches to achieve multiple (potential) impacts. This review will critically explore how this social innovation case study has exemplified the complex interplay between factors driving distortions in access to and availability of fish within the local food system. Through collaborative multi-stakeholder (transdisciplinary) processes, using participatory creative methods, new strategies and recommendations for research, practice, action and policy are informed, all of which offer great potential for progressive and transformative systemic (blue) food system change.

Myasthenia gravis (MG) is an autoimmune neuromuscular disorder characterized by fatigable weakness and increased perioperative vulnerability. Postoperative myasthenic crisis, defined as respiratory failure requiring prolonged ventilation or re-intubation, remains a feared complication after surgical procedures such as thymectomy. The efficacy of preoperative interventions such as intravenous immunoglobulin (IVIg) and plasmapheresis remains uncertain. This review examines the evidence supporting risk stratification tools and immunomodulatory strategies to prevent postoperative myasthenic crisis. A comprehensive literature review was conducted focusing on studies evaluating the incidence, risk factors and preventive strategies for postoperative myasthenic crisis in MG patients. Particular emphasis was placed on clinical predictive models and randomized trials assessing preoperative IVIg and plasmapheresis. Recent data suggest the incidence of postoperative myasthenic crisis has declined to below 10%, largely due to advances in surgical technique and perioperative care. Established risk factors include bulbar involvement, reduced pulmonary function and prior crises. Risk prediction models such as the Leuzzi and Kanai scores offer clinically useful stratification. While older retrospective studies favored preoperative plasmapheresis, meta-analyses and randomized trials have yielded mixed results. Randomized trials of IVIg have shown no significant benefit in well-controlled patients, and both interventions carry notable risks and costs. Current evidence does not support the routine use of IVIg or plasmapheresis prior to surgery in all MG patients. A targeted, risk-based approach guided by validated predictive models is recommended to minimize unnecessary interventions and health care system costs.

Positive food consumption remains one of the most common challenges among older adults in the UK with at least 10% in community settings and up to 45% in care homes affected by malnutrition. It is strongly associated with frailty, functional and health decline. Tracking and understanding the impact of diet is not easy. There are problems with monitoring diet and malnutrition screening such as difficulty remembering, lack of time, or needing a dietician to interpret the results. Computerised tailored education may be a positive solution to these issues. Due to the rise in smartphone ownership the use of technology to monitor diet is becoming more popular. This review paper will aim to look at the issues with current methods of dietary monitoring particularly in older adults, it will present the benefits and barriers of using to monitor food intake. It will discuss how a photo food monitoring app was developed to address the current issues with technology and how it was tested with older adults living in community and care settings. The prototype was co-developed and incorporated automated food classification to monitor dietary intake and food preferences and tested with older adults. The prototype was usable to both older adults and care workers and feedback on how to improve its use was collected. Key design improvements to make it quicker and more accurate were suggested for future testing in this population. With adaptions this prototype could be beneficial to older adults living in both community and care settings.

Growing demand for social care and resource constraints compel decision-makers to decide how to allocate public resources to social care. Such decisions may result in differences in access to social care between groups in society. In this study we conducted a secondary analysis of articles included in a systematic review on the underpinnings of resource allocation decisions in social care, extending that work to examine the potential consequences of such decisions. We conducted the review in accordance with the PRISMA framework. Through a thematic framework analysis of 37 of the 42 articles included in the parent review, we identified five groups in society that may be disproportionately affected by the consequences of resource allocation decisions on social care: (1) individuals with long-term social care needs (2) informal caregivers, (3) lower socio-economic groups, (4) individuals with limited health literacy skills, and (5) individuals living across different regions. Our findings highlight that allocation decisions in social care particularly affect women and individuals facing language barriers and may create local variation in provision of social care. These findings suggest potential for inequitable access to social care in society and underscore the need for decision-makers to consider the consequences of their allocation decisions.

Ensuring adequate food intake among older people is essential for maintaining health and preventing malnutrition. This review explores strategies to enhance dietary intake in this population group. Several key interventions are highlighted, including offering high-energy and protein-fortified meals and snacks, optimising the visual appeal and presentation of foods, enhancing flavours, and providing finger foods or modified textures to support consumption. Familiarity with fortified foods may encourage acceptance and increase intake, while improving food aesthetics and incorporating varied flavours can enhance enjoyment and promote consumption. Flavour enhancement may help compensate for decline in smell and taste sensitivity often experienced by older people, helping to sustain interest in food and promote greater intake. Finger foods present a practical solution for older adults with physical impairments, allowing for easier handling and self-feeding. Additionally, for individuals with dysphagia or chewing difficulties, texture-modified diets tailored to their needs support safe food intake. Research suggests that refining food presentation through techniques such as moulding and 3D printing may improve palatability and appeal, potentially boosting consumption among older adults. Addressing sensory preferences and physical challenges associated with eating is critical to ensuring adequate nutrition and promoting overall wellbeing in the elderly population. This review underscores the importance of multifaceted dietary strategies, advocating for personalised interventions that align with older individuals’ needs and preferences to enhance food intake and nutritional status.

Amerotyphlops brongersmianus (Vanzolini, 1976) is the only representative of its family in Argentina, and to date, there have been no records of its parasites. Between 2013 and 2018, 46 specimens of A. brongersmianus were collected in Corrientes province and investigated for helminths. Eighty-three specimens of Serpentirhabdias aff. vellardi were collected from the lungs of nineteen hosts. Sixty-nine percent of the nematodes were collected from the vascular lung mostly, with a prevalence of 41.3% and a mean intensity of 3.74 worms. Adult snakes had higher prevalence and mean abundance than juveniles; the mean intensity was similar between sexes and sexual maturity groups. The association between sexual maturity and the presence of lungworms was statistically significant. Lungworm abundance, weight, and length of adult snakes showed weak to strong positive correlations, with stronger correlations in males; however, these were not statistically significant. Nematodes followed a negative binomial distribution. Seasonal differences in parasitological descriptors and mean body length of lungworms were not statistically significant. Nonetheless, a significant negative correlation was observed between lungworm abundance and body length in spring, suggesting a clustering effect. Our results are discussed based on host phenology, ecology, biology, and anatomy. The life cycles of lungworms, the abundance of potential transport hosts, as well as abiotic factors (rainfall and temperature), are also considered. This is the first report of lungworms in A. brongersmianus throughout its range, the second global report of helminths in a Typhlopidae species in the 21st century, and the first in South America and Argentina, providing ecological data.

To determine values for the digestible indispensable amino acid score (DIAAS), it is recommended that ileal amino acid (AA) digestibility values obtained in growing pigs are used to characterise protein quality in different foods. Therefore, an experiment was conducted to determine the standardised ileal digestibility (SID) of AA in eight energy ingredients (barley, sorghum, wheat, brown rice, rice bran, wheat bran, cassava and paddy rice) fed to pigs, where SID values in pigs can be used to calculate approximate DIAAS values in humans. Among the data obtained for all energy ingredients, significant variations (P < 0·01) in CP and AA composition were observed. Rice bran and wheat bran had the highest CP (16·43 % and 18·16 %, respectively) and DIAAS scores of 81–88 for adult, qualifying as ‘good’ protein sources (> 75). Cassava, with the lowest CP (2·74 %), was limited by sulphur amino acid (54). Lysine (Lys) was the first-limiting AA in barley (74), sorghum (51) and wheat (49), with SID values lowest in wheat (71·04 %). Brown rice and paddy rice showed higher SIDLys (87·51 % and 78·13 %, respectively). These findings highlight the potential of bran-based ingredients and Lys fortification to improve protein quality in grain-dependent diets, providing the scientific basis to combat protein malnutrition.
