Subgingival restorations are problematic due to reduced visibility at the preparation margins, humidity (saliva, crevicular fluid and/or blood), problems with taking impressions (digital or analogue) and problems with the application of a rubber dam. Solutions, such as the use of a surgical microscope, retraction cord and Teflon tape, are available. Since modern dentistry largely relies upon adhesive techniques with hydrophobic materials, these require a clean and dry working area. One solution is to place the preparation margin supragingivally. This can be done in three ways: a local build-up using a direct composite restoration, a surgical clinical crown lengthening or an extrusion (orthodontic or surgical). Since in practice only a small part is usually located subgingivally, placing a direct composite restoration is often sufficient. The term Deep Margin Elevation is generally used in the international English-language literature for this approach. If the area located subgingivally is larger, then techniques like crown lengthening and extrusion might be better.

PURPOSE OF REVIEW
Enteral feeding is commonly used to provide patients with nutrition. Access via feeding tubes can be attained by multiple medical specialties through a variety of methods.
RECENT FINDINGS
There are limited data available on direct comparisons amongst gastroenterologist, interventional radiologists and surgeons, although there appears to be similar rates of complications. Fluroscopically and surgically placed feeding tubes may have a higher technical success rate than endoscopically placed tubes. The preferred specialty for feeding tube placement varies per institution, often due to logistical matters over technique or concern for complications. Ideally, a multidisciplinary team should exist to determine which approach is best in a patient-specific manner.

Research has the potential to simultaneously generate new knowledge and contribute meaningful social-ecological benefits; however, research processes and outcomes can also perpetuate extractive patterns that have manifested the climate, biodiversity, and social justice crises. One approach to enhance the societal value of research processes is to strengthen relationships with places of study and the peoples of those places. Deepening relational engagement with the social-ecological context and history of a place can lead to more accurate results and improved public trust in the scientific process and is particularly important for natural scientists who work at the interface of nature and society. We provide three actionable pathways that range from individual to systemic change to enhance place-based relationships within research systems: 1) deepen reflection and communication about relationships with places and peoples; 2) strengthen collaboration among research teams and partners; and 3) transform systems of knowledge creation to foster place-based roots. Action on any of these proposed pathways, but especially action taken across all three, can build empathy and connections to place and people, strengthening the meaningful impact of research both locally and globally.

Migrants are faced with the task of creating a sense of home in a new context. As migrants grow older in their host countries, they are also making important decisions on where to live out the rest of their lives, making salient the places they attach themselves to. Place attachment, and its subcomponents of place identity and place dependence, are concepts that have been explored in the ageing and migration literature, demonstrating that positive, emotional attachments to places are positively correlated with better health outcomes. Although it has been established that individuals' attachments to places are dynamic, multidimensional and change over the life course, there is a paucity of research exploring the place attachments of migrants as they age using a life course approach. This study adopted a life course approach to investigate how the components of place attachment shifted over time for migrant people in Aotearoa New Zealand as they aged, and to better understand the mechanisms and barriers to establishing a sense of home in a foreign land. We examined the narratives of ten older migrants (65 years or older) who migrated to Aotearoa before the age of 50. Key findings illustrated that all participants had strong place identities (i.e., explicit self-identification and sense of belonging) to their countries of origin before migrating to Aotearoa, all participants developed strong place dependence (i.e., fulfilment of functional needs) to Aotearoa over their life course, but not everyone was able to develop place identity to Aotearoa. Mechanisms such as language, cultural attitudes, and values can both facilitate and prevent attachments to either home or host country. These results uncover how Aotearoa's ageing migrants negotiate their attachments to places over the life course.

Review
Stress urinary incontinence is a financially burdensome and socially isolating problem and can be experienced by men as a result of radical prostatectomy, radiation therapy, or other urologic surgery. Artificial urinary sphincter (AUS) placement for stress urinary incontinence is considered the 'gold standard' for male stress urinary incontinence. While initially only placed by specialized prosthetic surgeons, changes in urologic training have made implantation of the device by general urologists more widespread. Additionally, even though a minority of urologists place the majority of implants, many urologists may find themselves caring for patients with these devices even if they have never placed them themselves. For this reason, it is paramount that the urologic surgeon implanting the device and those caring for patients with prostheses are familiar with the various perioperative and postoperative complications of AUS implantation. This review discusses the most commonly reported complications of AUS implantation as well as those that are rarely described. Knowledge of these potential complications is necessary in order to care for patients with urologic implants.

Review
If a full visual percept can be said to be a 'hypothesis', so too can a neural 'prediction' - although the latter addresses one particular component of image content (such as 3-dimensional organisation, the interplay between lighting and surface colour, the future trajectory of moving objects, and so on). And, because processing is hierarchical, predictions generated at one level are conveyed in a backward direction to a lower level, seeking to predict, in fact, the neural activity at that prior stage of processing, and learning from errors signalled in the opposite direction. This is the essence of 'predictive coding', at once an algorithm for information processing and a theoretical basis for the nature of operations performed by the cerebral cortex. Neural models for the implementation of predictive coding invoke specific functional classes of neuron for generating, transmitting and receiving predictions, and for producing reciprocal error signals. Also a third general class, 'precision' neurons, tasked with regulating the magnitude of error signals contingent upon the confidence placed upon the prediction, i.e., the reliability and behavioural utility of the sensory data that it predicts. So, what is the ultimate source of a 'prediction'? The answer is multifactorial: knowledge of the current environmental context and the immediate past, allied to memory and lifetime experience of the way of the world, doubtless fine-tuned by evolutionary history too. There are, in consequence, numerous potential avenues for experimenters seeking to manipulate subjects' expectation, and examine the neural signals elicited by surprising, and less surprising visual stimuli. This review focuses upon the predictive physiology of mouse and monkey visual cortex, summarising and commenting on evidence to date, and placing it in the context of the broader field. It is concluded that predictive coding has a firm grounding in basic neuroscience and that, unsurprisingly, there remains much to learn.

Review
BACKGROUND
Palliative care necessitates questions about the preferred place for delivering care and location of death. Place is integral to palliative care, as it can impact proximity to family, available resources/support, and patient comfort. Despite the importance of place, there is remarkably little literature exploring its role in pediatric palliative care (PPC).
OBJECTIVES
To understand the importance and meaning of place in PPC.
METHODS
We conducted a scoping review to understand the importance of place in PPC. Five databases were searched using keywords related to "pediatric," "palliative," and "place." Two reviewers screened results, extracted data, and analyzed emergent themes pertaining to place.
RESULTS
From 3076 search results, we identified and reviewed 25 articles. The literature highlights hospital, home, and hospice as 3 distinct PPC places. Children and their families have place preferences for PPC and place of death, and a growing number prefer death to occur at home. Results also indicate numerous factors influence place preferences (e.g., comfort, grief, cultural/spiritual practices, and socioeconomic status).
SIGNIFICANCE OF RESULTS
Place influences families' PPC decisions and experiences and thus warrants further study. Greater understanding of the importance and roles of place in PPC could enhance PPC policy and practice, as well as PPC environments.

Review
BACKGROUND
Livability is a concept commonly featured in health research to help shape public policy decisions and improve local place settings. Although widely used, it is a contested concept known for its ambiguity and inconsistency of measurements. Other criticisms include the lack of equity perspectives and the underrepresentation of people with disabilities and inhabitants of non-metropolitan places.
OBJECTIVES
This review sought to identify the extent to which people with disabilities and non-metropolitan places are included in measurements of livability and to critically review and summarise i) livability definitions and uses, ii) livability places and populations, and iii) livability measurements.
METHODS
The scoping review followed Arksey and O'Malley's methodological framework and the PRISMA extension for scoping reviews. The data extraction used meta-aggregation techniques to evaluate findings. A standardised mixed methods appraisal tool was used, and a novel classification of measurements was created.
RESULTS
Seventy-seven articles were included, and 1955 measurements were extracted. The overarching findings were: i) livability is inconsistently defined and assessed by measuring the performance of related and independent domains, ii) the population sample or the studies' participants are often not disclosed, non-metropolitan settings are overlooked, and equity is not generally applied or operationalised in measurements, and iii) there is an extensive lack of measurements considering people with disabilities and diversity within disabilities.
CONCLUSIONS
The assumptions of homogeneity in study populations in livability measurement literature overlook inequities experienced by people with disabilities and inhabitants of non-metropolitan settings. This review suggests recommendations for future research to assess livability from perspectives inclusive of human diversity.

INTRODUCTION
In contemporary society, people spend long periods under high stress, and tourism activities have gradually been internalized as a new means of stress release and self-recovery. Studies have found that the high-quality natural environment of rural tourism destinations has a higher restorative effect than other places, and the rural natural environment can provide psychological recovery to visitors on top of offering visual beauty and other experiences.
METHODS
This paper starts with the relationship between rural place perception and restorative experience evaluation. Based on theories such as the restorative environments theory, we investigates whether rural natural environmental factors have a restorative effect on recreationists through collecting 300 questionnaires and using SPSS 26.0 structural equation modeling for analysis.
RESULTS
The study found that there is a positive correlation between rural natural perception, place dependence, and restorative experience, forming a positive feedback loop dynamic system. The analysis suggests that enhancing the perception of the rural natural environment and place attachment can improve the restorative experience of recreationists in rural settings.
DISCUSSION
This research establishes a systematic research framework for the relationship between rural natural perception, place attachment, and restorative experience, to deeply understand the dynamic interaction between them. It reveals the relationship between rural natural perception and restorative experience, suggesting that enriching the perceptual elements in rural natural spaces can meet the diverse needs of recreationists, enhance the sense of dependence and identification with rural spaces, and thus promote the psychological well-being and restorative experience of recreationists. The study also finds that place dependence plays a mediating role between rural natural perception and restorative experience. Place attachment and place identity, as mediating variables, act as bridges and catalysts in the process of rural natural perception affecting restorative experience.
