Supermarkets have been described as having unprecedented and disproportionate power in the food system, influencing population diets through the products they have for sale, their price, store layouts, and other marketing activities(1).There is growing evidence to suggest that changing the retail food environment to be more health-enabling via in-store interventions is possible. The purpose of this study was to review the available high-quality evidence reporting on the effectiveness of real-world supermarket-based interventions on improving the healthiness of consumer purchases and consumption. First, a systematic search across seven electronic databases was completed in April 2023 to identify reviews describing the effects of intervention strategies that aimed to improve the healthiness of consumer purchasing in supermarkets and grocery stores (overview of reviews). The methodological quality of reviews was assessed using the Risk of Bias In Systematic Reviews for systematic and scoping reviews, and the Scale for the Assessment of Narrative Review Articles for narrative reviews. Review findings were synthesised narratively. Next, high-quality, primary studies from these reviews were further inspected (review of primary studies). In-store interventions were categorised by strategy type(2), and outcome effects were coded as effective (positive/promising), ineffective or mixed/unclear(3). Results were synthesised narratively, and separately for population subgroups. Thirty-eight reviews published between 1989 and 2023 met the inclusion criteria. Most were systematic reviews (n = 29, 76%). The number of primary studies included in reviews ranged between eight and 211. Prompting (n = 19, 50%) and pricing (n = 15, 40%) were the most assessed strategy type, either alone or in combination with another strategy. From the overview of reviews, pricing strategies appeared to be the most promising at improving consumer purchasing. Twenty-three high-quality primary studies met the inclusion criteria for further review. In most studies (n = 21, 91%), the goal was to increase sales of healthy products, most commonly fruit and vegetables, or products with a higher nutritional ranking. Only two studies (9%) aimed to exclusively reduce sales of unhealthy/less healthy products. Promotion was the most assessed strategy type (n = 11, 48%), either alone or in combination with another strategy. Common promotion strategies included providing education to customers about the health benefits of selected products, offering samples of products and giving food demonstrations. From the review of primary studies, promotional strategies used in combination with another strategy appeared to be most successful in the general population, and pricing was successful in subgroups of the population, including socioeconomically disadvantaged individuals, and those living in regional/remote areas. Overall, the evidence reviewed shows that the implementation of health-promoting supermarket interventions are more likely to be successful if they include a substantial pricing initiative (particularly for some subgroups), or the inclusion of promotion in combination with another strategy.

Summary
In perioperative medicine, optimal fluid management during and after the surgery is often debated. However, it is clear that poor fluid management and periods of hypotension are closely linked to worse outcomes. Both excessively liberal and restrictive fluid regimens lead to harm. Goal-directed pathways, where fluid or vasopressor administration targets a predefined hemodynamic parameter, are occasionally used. However, these require advanced hemodynamic monitoring, have limited evidence to support them and are often too complex, resulting in unsuccessful implementation.
Artificial intelligence (AI) focuses on machines capable of replicating human decision making. Within AI, predictive analytics use existing data to predict future events. These predictions can be integrated into open- or closed-loop systems, guiding fluid or vasopressor administration and reducing the clinician’s cognitive burden. This chapter provides an introduction to predictive analytics in perioperative fluid management, an overview of published literature, andsuggestions as to how the technology might develop in the future.

Summary
Empathy, the capacity to share and understand others’ states, is crucial for facilitating enduring social relationships and managing ingroup and outgroup dynamics. Despite being at the center of much scrutiny and debate in human research, the evolutionary foundations of empathy remain relatively opaque. Moreover, inconsistencies remain regarding definitions and theoretical models, leading to discrepancies in how to systematically represent and address empathy and understand its evolutionary basis. As a complex, multidimensional phenomenon, certain components of empathy are likely to be evolutionarily ancient whereas others may be more derived. As our closest living relatives, nonhuman primates provide an opportunity to explore the evolutionary origins of empathy and its subcomponents. Due to the rich diversity of primate societies, we can comparatively study evidence of affective responding and empathic behavior within the context of different social dynamics and organization. Although studies have been conducted on individual primate species, especially the great apes, direct species comparisons are rare. Here we examine the literature investigating evidence for empathy among primates focusing on its underlying affective and cognitive components. In reviewing the literature, we also highlight species that need more coverage to enhance our overall understanding of how empathy has evolved within the primate order.

Introduction
People living with dementia or mild cognitive impairment (MCI) experience stigmatisation and there are not many specific psychosocial interventions dedicated to help them coping with this issue, reducing its impact on their lives.
ObjectivesThis study aimed to a) investigate the stigmatisation level among people with dementia and MCI in Poland, Italy and the United Kingdom and b) assess the role of the Meeting Centre Support Programme (MCSP) in decreasing stigmatisation.
MethodsWe investigated outcomes for 114 people with dementia and MCI living in Italy, Poland and the UK who participated 6 months in MCSP or usual care (UC) using a pre/post-test control group study design. Level of stigmatisation was assessed with the Stigma Impact Scale: neurological impairment (SIS).
ResultsStigmatisation level (SIS) among participants varied from 2 to 65 (median=33.5; Q1=27; Q3=41) with people from the UK experiencing a statistically significantly higher level of stigmatisation than people in Italy and Poland. In Italy, stigmatisation was lower (p=0.02) in the MCSP group following the intervention. In Poland, the social isolation level did not significantly change in MCSP, but increased (p=0.05) in UC. In the UK, the social rejection level raised (p=0.03) in MCSP. Overall, the combined data of the three countries did not show statistically significant differences in SIS between MCSP and UC.
ConclusionsStigmatisation among people with dementia and MCI is complex and seems culturally dependent. There is a great opportunity in psychosocial interventions to reduce the burden of stigma among people with dementia which requires further investigation.

Introduction
The Meeting Centre Support Programme (MCSP) is a community-based approach to support people living with dementia and their families. It was developed in the Netherlands and has been implemented in other European Countries (Italy, Poland and the UK) within the JPND-MEETINGDEM project.
AimsTo assess the relationship between background characteristics of people with dementia participating in MCSP, mood, quality of life (QoL) and experienced stigma, and to explore if and how the experienced stigma changed after 6 months of participation in MCSP.
MethodsA pretest (M1) post-test (M7) control group design with matched groups regarding severity of dementia was applied. In each country, a minimum of 25 participants using MCSP were compared with people with dementia receiving ‘usual care’. Data were collected with the Stigma Impact Scale, Cornell Scale for Depression in Dementia, Global Deterioration Scale and two QoL scales (QoL-AD & DQoL). Differences in background characteristics were taken into account in the analyses.
ResultsThe preliminary analysis on 116 participants at baseline shows that the level of stigma was low to moderate. People felt more socially rejected in the UK than in Poland and Italy. The level of perceived stigmatization appeared negatively correlated with QoL areas and positively correlated with negative mood. Changes after 6 months will be presented.
ConclusionsIt is expected that after 6 months people living with dementia participating in MCSP will experience less stigma, as in contrast with usual care MCSP promotes social integration of people with dementia and person-centered support.

Background:
In the MEETINGDEM project, the Meeting Centers Support Program (MCSP) was adaptively implemented and evaluated in three European countries: Italy, Poland, and the United Kingdom. The aim of this study was to investigate overall and country-specific facilitators and barriers to the implementation of MCSP in these European countries.
Methods:A qualitative multiple case study design was used. Based on the theoretical model of adaptive implementation, a checklist was composed of potential facilitators and barriers to the implementation of MCSP. This checklist was administered among stakeholders involved in the implementation of MCSP to trace the experienced facilitators and barriers. Twenty-eight checklists were completed.
Results:Main similarities between countries were related to the presence of suitable staff, management, and a project manager, and the fact that the MCSP is attuned to needs and wishes of people with dementia and informal caregivers. Main differences between countries were related to: communication with potential referrers, setting up an inter-organizational collaboration network, receiving support of national organizations, having clear discharge criteria for the MCSP and continuous PR in the region.
Conclusion:The results of this study provide insight into generic and country specific factors that can influence the implementation of MCSP in different European countries. This study informs further implementation and dissemination of MCSP in Europe and may also serve as an example for the dissemination and implementation of other effective psychosocial support interventions for people with dementia and their informal caregivers across and beyond Europe.

A characteristics model, which assumes goods generate a common set of attributes but no unique attribute, is described. The model yielded two equations which were estimated. One was a set of hedonic price equations in which the price paid for each food purchased was a function of imputed attribute prices. This set of equations was estimated at the household level. Nutrient demand equations were estimated across households. Imputed prices, income, and household characteristics including location, size, education, age distribution, and race affected nutrient demand levels.

Parasites have a major impact on global finfish and shellfish aquaculture, having significant effects on farm production, sustainability and economic viability. Parasite infections and impacts can, according to pathogen and context, be considered to be either unpredictable/sporadic or predictable/regular. Although both types of infection may result in the loss of stock and incur costs associated with the control and management of infection, predictable infections can also lead to costs associated with prophylaxis and related activities. The estimation of the economic cost of a parasite event is frequently complicated by the complex interplay of numerous factors associated with a specific incident, which may range from direct production losses to downstream socio-economic impacts on livelihoods and satellite industries associated with the primary producer. In this study, we examine the world's major marine and brackish water aquaculture production industries and provide estimates of the potential economic costs attributable to a range of key parasite pathogens using 498 specific events for the purposes of illustration and estimation of costs. This study provides a baseline resource for risk assessment and the development of more robust biosecurity practices, which can in turn help mitigate against and/or minimise the potential impacts of parasite-mediated disease in aquaculture.

Introduction:
The main purpose of this study was to investigate the psychological and functional impact attributed to acoustic neuroma symptoms.
Materials and methods:A sample of 207 acoustic neuroma patients completed a study-specific questionnaire about the severity, frequency, and psychological and functional impact of 9 acoustic neuroma symptoms.
Results:The survey response rate was 56.4 per cent. All symptoms had some degree of psychological impact for the majority of participants; hearing loss was the symptom most often reported to have a severe psychological impact. The majority of respondents reported functional impact attributed to hearing loss, balance disturbance, dizziness, eye problems, headache and fatigue; balance disturbance was the symptom most often reported to have a severe functional impact. For most symptoms, psychological and functional impact were related to severity and frequency.
Conclusion:Of the acoustic neuroma symptoms investigated, hearing loss and balance disturbance were the most likely to have a severe psychological and functional impact, respectively.

The life cycle of the parasitic copepod Lernaeocera branchialis involves 2 hosts, typically a pleuronectiform host upon which development of larvae and mating of adults occurs and a subsequent gadoid host, upon which the adult female feeds and reproduces. Both the copepodid and adult female stages must therefore locate and identify a suitable host to continue the life cycle. Several mechanisms are potentially involved in locating a host and ensuring its suitability for infection. These may include mechano-reception to detect host movement and chemo-reception to recognize host-associated chemical cues, or kairomones. The aim of this study was to identify the role of kairomones in host location by adult L. branchialis, by analysing their behaviour in response to fish-derived chemicals. Experiments demonstrated that water conditioned by immersion of whiting, Merlangius merlangus, elicited host-seeking behaviour in L. branchialis, whereas cod- (Gadus morhua) conditioned water did not. Lernaeocera branchialis are considered a genetically homogeneous population infecting a range of gadoids. However, their differential response to whiting- and cod-derived chemicals in this study suggests that either there are genetically determined subspecies of L. branchialis or there is some form of environmental pre-conditioning that allows the parasite to preferentially recognize the host species from which it originated.

In May 2001, the World Health Assembly (WHA) passed a resolution which urged member states to attain, by 2010, a minimum target of regularly administering anthelminthic drugs to at least 75% and up to 100% of all school-aged children at risk of morbidity. The refined global strategy for the prevention and control of schistosomiasis and soil-transmitted helminthiasis was issued in the following year and large-scale administration of anthelminthic drugs endorsed as the central feature. This strategy has subsequently been termed ‘preventive chemotherapy’. Clearly, the 2001 WHA resolution led the way for concurrently controlling multiple neglected tropical diseases. In this paper, we recall the schistosomiasis situation in Africa in mid-2003. Adhering to strategic guidelines issued by the World Health Organization, we estimate the projected annual treatment needs with praziquantel among the school-aged population and critically discuss these estimates. The important role of geospatial tools for disease risk mapping, surveillance and predictions for resource allocation is emphasised. We clarify that schistosomiasis is only one of many neglected tropical diseases and that considerable uncertainties remain regarding global burden estimates. We examine new control initiatives targeting schistosomiasis and other tropical diseases that are often neglected. The prospect and challenges of integrated control are discussed and the need for combining biomedical, educational and engineering strategies and geospatial tools for sustainable disease control are highlighted. We conclude that, for achieving integrated and sustainable control of neglected tropical diseases, a set of interventions must be tailored to a given endemic setting and fine-tuned over time in response to the changing nature and impact of control. Consequently, besides the environment, the prevailing demographic, health and social systems contexts need to be considered.

A prominent filamentous and granular cell coat is associated with the plasma membraneof haptomonads of Crithidia fasciculata attached to the cuticular lining of the hindgut of Anopheles gambiae. This surface material is completely absent from morphologically identical haptomonads from the mosquito foregut and from rosettes in culture. On the basis of these observations, it is suggested that cell coat formation is dependent on suitable environmental conditions. A cytochemical staining technique indicates the presence of carbohydrates in (a) the cell coat, (b) the outer leaflet of the plasma membrane of haptomonads from all locations and (c) small cytoplasmic vesicles and multivesicular bodies in all haptomonads. It is suggested that these cytoplasmic organelles represent stages in the intracellular pathway for material ingested by pinocytosis rather than elements involved in surface coat formation.

The spatial epidemiology of intestinal nematodes in Uganda was investigated using generalized additive models and geostatistical methods. The prevalence of Ascaris lumbricoides and Trichuris trichiura was unevenly distributed in the country with prevalence greatest in southwest Uganda whereas hookworm was more homogeneously distributed. A. lumbricoides and T. Trichiura prevalence were nonlinearly related to satellite sensor-based estimates of land surface temperature; hookworm was nonlinearly associated with rainfall. Semivariogram analysis indicated that T. trichiura prevalence exhibited no spatial structure and that A. lumbricoides exhibited some spatial dependency at small spatial distances, once large-scale, mainly environmental, trends had been removed. In contrast, there was much more spatial structure in hookworm prevalence although the underlying factors are at present unclear. The implications of the results are discussed in relation to parasite spatial epidemiology and the prediction of infection distributions.

A method of extracting cheese juice is described. Juice from a single one-month-old Cheddar cheese was used to investigate the relationship between the composition of the cheese juice and the occurrence of crystalline aggregates in the cheese. Two classes of crystalline aggregates were identified by light microscopy and also by electron microscopy in combination with X-ray microanalysis: the larger class contained both Ca and P whereas the smaller class contained Ca but not P. Concentrations of ions in the cheese and cheese juice were determined and corrected for the excluded volume of co-solutes and other phases present. When this was done, comparison of the concentrations of Na, K, Cl and lactate in the cheese and the cheese juice indicated that they were virtually entirely in solution, whereas appreciable amounts of the total Ca, P and P1 in the cheese were not extracted in the cheese juice. The amounts of the non-extractable salts were consistent with the volume fractions of the crystalline aggregates found by microscopy; calculations of the ion equilibria in the cheese juice showed that it was supersaturated with respect to various Ca phosphate salts and to tricalcium citrate. It is concluded that the physicochemical origin of the crystalline aggregates was the nucleation and growth of crystals from a supersaturated solution, though the sites of nucleation may have been formed by the microbial activity in the cheese. Of the free amino acids found in the juice, none was at a sufficiently high concentration to form a saturated solution, indicating that in this relatively young cheese the crystalline aggregates were not formed from amino acids.

Investigation of the effect of pH on the formation of deposit from milk during ultra high temperature treatment using a plate-type plant showed that deposit formation was greatly increased when the pH of whole milk was reduced to 6·54, irrespective of whether the adjustment was made through the addition of HCl or lactic acid. Most of the increase in deposition took place in the higher temperature sections of the plant. Conversely, an increase in milk pH to 6·8 using NaOH resulted in considerably less deposit being formed during heat treatment. Reducing the pH of whole milk increased the deposition of both protein and fat, but reduced the deposition of minerals. Despite very high concentration of fat in the deposits, it is unlikely that fat per se was responsible for increased deposit formation. Deposition also increased when the pH of skim milk was reduced to 6·51 before processing. Electron micrographs of the milks after heat treatment indicated that pH reductions caused the formation of large aggregates containing casein micelles during heating. Fat globules were also present in aggregates formed in whole milk with reduced pH. Slight reductions in the pH of milk before processing appear to enable the pH during heat treatment to fall below a critical value at which coagulation of milk takes place at the heated surfaces.

Sections (1–5 μm thick) of epoxy resin-embedded cheese curd, yogurt, whipped cream and cream cheese were etched by treatment with warm alcoholic NaOH. Thin specimens were produced which could be metal coated and examined by scanning electron microscopy using accelerating voltages of at least 30 kV without producing charging problems. The images observed were easy to interpret and could be used to produce quantitative results. Although native milk fat globules did not survive the etching process, homogenized milk fat was not adversely affected. Critical point drying of etched sections produced results superior to those obtained by air drying.

Particles as large as several µm diam. have been observed occasionally in normal milk and commonly in prepartum and postpartum colostrum. These particles can be dissociated by EDTA and their appearance closely resembles that of normal casein micelles. However, they are often too large to have been completely formed within the Golgi vesicles of mammary epithelium and hence some degree of post-secretory aggregation of caseins is thought to occur. Two possible mechanisms of post-secretory aggregation of caseins are: (1) a continuation of the normal processes of micelle assembly in the alveolus and (2) aggregation as a result of limited proteolysis of the caseins during the time the milk is in the mammary gland. Incubation of milk with fibrinolysin, however, failed to produce aggregation of normal micelles.

Bovine casein micelles in pre- and post-partum colostrum have been characterized by both electron microscopy and light scattering. Attempts have been made to relate the changes in average micelle size to the partitioning of Ca and inorganic orthophosphate betwen the colloidal and aqueous phases. Pre-partum colostrum, and to a decreasing extent post-partum colostrum, contain casein micelles several microns in diameter. These giant micelles often contain closed cavities suggesting that they are formed by aggregation of particles comparable in size to normal casein micelles. Electron microscopy of mammary gland alveoli from nearterm pregnant heifers shows clear differences in average size between micelles immediately before and after secretion from Golgi vesicles. It appears that micelles aggregate in the alveolar lumen, possibly as a result of continuing co-precipitation of casein with Ca phosphate.
