The taste of food plays a crucial role in determining what and how much we eat. Thus, interventions that temporarily block sweet taste receptors offer a promising approach to addressing unhealthy behaviours associated with sugary foods. However, the relationship between reduced sweet taste response and food consumption remains unclear, with contradictory findings. Certain studies suggest that a diminished perception of sweetness leads to a sense of fullness and results in reduced food intake, while others suggest the opposite effect. To shed some light, our systematic review looked into the relationship between diminished sweet taste response and food consumption by examining the effects of bioactive compounds that experimentally inhibit sweetness in healthy individuals. This review was registered in the International Prospective Register of Systematic Reviews and conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and the Scottish Intercollegiate Guidelines Network, and covered original papers included in Web of Science, PubMed, Scopus, Food Science Source and Food Science and technology abstracts. We identified 33 peer-reviewed English-language studies that fit the topic and met the inclusion criteria. The current literature predominantly focuses on the immediate impact of oral gymnemic acids, failing to provide preliminary evidence in support of the specific threshold hypothesis, above which food consumption decreases and below which the opposite effect occurs. Additionally, there was inconsistency in the findings regarding the short-term desire to eat following sweetness inhibition. Considering the downstream effects on energy intake and their clinical applications, further research is needed to clarify both the acute within-session effects (i.e., not wanting any more now) and the longer-term effects (i.e., deciding not to start eating) linked to oral sweet-taste-suppressing compounds.

Meta-Analysis
Historically, religion has had a central role in shaping the psychosocial and moral development of young people. While religiosity and spirituality have been linked to positive mental health outcomes in adults, their role during the developmental context of adolescence, and the mechanisms through which such beliefs might operate, is less well understood. Moreover, there is some evidence that negative aspects of religiosity are associated with poor mental health outcomes. Guided by lived experience consultants, we undertook a systematic review and quality appraisal of 45 longitudinal studies and 29 intervention studies identified from three electronic databases (Medline, PsycINFO and Scopus) exploring the role of religiosity and spiritual involvement (formal and informal) in prevention and management of depression and anxiety in young people aged 10 to 24 years. Most studies were from high-income countries and of low to moderate quality. Meta-analysis of high-quality longitudinal studies (assessed using Joanna Briggs Institute critical appraisal tools, n = 25) showed a trend towards association of negative religious coping (i.e., feeling abandoned by or blaming God) with greater depressive symptoms over time (Pearson's r = 0.09, 95% confidence interval (CI) -0.009, 0.188) whereas spiritual wellbeing was protective against depression (Pearson's r = -0.153, CI -0.187, -0.118). Personal importance of religion was not associated with depressive symptoms overall (Pearson's r = -0.024, CI-0.053, 0.004). Interventions that involved religious and spiritual practices for depression and anxiety in young people were mostly effective, although the study quality was typically low and the heterogeneity in study designs did not allow for a meta-analysis. The lived experience consultants described spirituality and religious involvement as central to their way of life and greatly valued feeling watched over during difficult times. While we require more evidence from low- and middle-income countries, in younger adolescents and for anxiety disorders, the review provides insight into how spirituality and religious involvement could be harnessed to design novel psychological interventions for depression and anxiety in young people.Review RegistrationThe systematic review was funded by Wellcome Trust Mental Health Priority Area 'Active Ingredients' 2021 commission and registered with PROSPERO 2021 (CRD42021281912).

As health-related big data research (HRBDR) has drastically increased over the last years due to the rapid development of big data analytics, a range of important ethical issues are raised. In this study, a systematic literature review was conducted. Several and interesting results emerged from this review. The term ″big data″ has not yet been clearly defined. The already existing ethical principles and concepts need to be revisited in the new HRBDR context. Traditional research ethics notions like privacy and informed consent are to be reconsidered. HRBDR creates new ethical issues such those related to trust / trustworthiness and public values such as reciprocity, transparency, inclusivity and common good. The implementation of dynamic consent rather than broad consent is currently highlighted as the more satisfying solution. Ethical review committees in their current form are ill-suited to provide exclusive ethical oversight on HRBDR projects. Expanding Ethical Review Committees' purview and members' expertise, as well as creating novel oversight bodies by promoting a co-governance system including public and all the stakeholders involved are strongly recommended. The mechanism of ″social licence″, that is, informal permissions granted to researchers by society, can serve as a guideline. High-stakes decisions are often made under uncertainty. Machine learning algorithms are highly complex and in some cases opaque, and may yield biased decisions or discrimination. Improved interdisciplinary dialogue along with considering aspects like auditing, benchmarking, confidence / trust and explainability /interpretability may address concerns about HRBDR ethics. Finally and most importantly, research ethics shifts towards a population-based model of ethics.

Human-animal chimera research has gradually evolved to the present day, in which large projects related to the attempt to solve pathologies that help us human beings to alleviate diseases. However, it must be considered that many of these advances in science imply an important ethical dilemma in many cases, and even more so if we involve people in said experiments. In the present systematic review we sought to identify these ethical problems related to chimeras, as well as possible solutions to them proposed in the literature, including technical means for the realization of less humanized chimeras. A bibliographic search was carried out in the Pubmed, Embase and Medes databases on January 4 th, 2022. The articles that strictly comply with the objectives selected for the completion of the work will be selected. A total of 21 articles makes up our sample, from which ethical problems related to chimeras, possible solutions and technical means to avoid obtaining too humanized chimeras will be extracted. The issues identified in the articles are problems related to animal welfare, acquisition of human traits from chimeras, medical concerns derived from experimentation such as zoonoses, the origin of pluripotential cells for chimera production, the creation of human gametes by said chimeras, neurological chimerism and the moral status of chimeras. This paper provides solutions for these problems, such as the use of suicide genes in human cells that would be activated if they differentiate into neuronal cells or the use of gene editing through the CRISPR/Cas9 mechanism to incapacitate these cells so that they do not differentiate into neuronal cells. The only question that remains elusive to the proposal of solutions is the one related to the potential moral status of chimeras. It is certainly a complex issue given the variety of proposals on the concept of moral status available in literature. It is therefore necessary to bring these proposals closer to reflection on human-animal chimeras in order to initiate a discussion that can shed light on this issue.

Meta-Analysis
BACKGROUND AND OBJECTIVES
The poor mental health of adults living in aged care needs addressing. Improvements to nutrition and exercise are important, but mental health requires a psychological approach. Self-determination theory finds that autonomy is essential to wellbeing while experiences of being controlled undermine it. A review of existing quantitative data could underscore the importance of autonomy in aged care, and a review of the qualitative literature could inform ways to promote autonomy and avoid control. Testing these possibilities was the objective of this research.
RESEARCH DESIGN AND METHODS
We conducted a mixed-methods systematic review of studies investigating autonomy, control, and indices of optimal functioning in aged care settings. The search identified 30 eligible reports (19 quantitative, 11 qualitative), including 141 quantitative effect sizes, 84 qualitative data items, and N = 2,668. Quantitative effects were pooled using three-level meta-analytic structural equation models, and the qualitative data were meta-synthesized using a grounded theory approach.
RESULTS
As predicted, the meta-analysis showed a positive effect of aged care residents' autonomy and their wellness, r = 0.33 [95% CI: 0.27, 0.39], and a negative effect of control, r = -0.16 [95% CI: -0.27, -0.06]. The meta-synthesis revealed seven primary and three sub-themes describing the nuanced ways autonomy, control, and help seeking are manifest in residential aged care settings.
DISCUSSION AND IMPLICATIONS
The results suggest that autonomy should be supported, and unnecessary external control should be minimized in residential aged care, and we discuss ways the sector could strive for both aims.

BACKGROUND
YouTube has become a popular source of health care information, reaching an estimated 81% of adults in 2021; approximately 35% of adults in the United States have used the internet to self-diagnose a condition. Public health researchers are therefore incorporating YouTube data into their research, but guidelines for best practices around research ethics using social media data, such as YouTube, are unclear.
OBJECTIVE
This study aims to describe approaches to research ethics for public health research implemented using YouTube data.
METHODS
We implemented a systematic review of articles found in PubMed, SocINDEX, Web of Science, and PsycINFO following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. To be eligible to be included, studies needed to be published in peer-reviewed journals in English between January 1, 2006, and October 31, 2019, and include analyses on publicly available YouTube data on health or public health topics; studies using primary data collection, such as using YouTube for study recruitment, interventions, or dissemination evaluations, were not included. We extracted data on the presence of user identifying information, institutional review board (IRB) review, and informed consent processes, as well as research topic and methodology.
RESULTS
This review includes 119 articles from 88 journals. The most common health and public health topics studied were in the categories of chronic diseases (44/119, 37%), mental health and substance use (26/119, 21.8%), and infectious diseases (20/119, 16.8%). The majority (82/119, 68.9%) of articles made no mention of ethical considerations or stated that the study did not meet the definition of human participant research (16/119, 13.4%). Of those that sought IRB review (15/119, 12.6%), 12 out of 15 (80%) were determined to not meet the definition of human participant research and were therefore exempt from IRB review, and 3 out of 15 (20%) received IRB approval. None of the 3 IRB-approved studies contained identifying information; one was explicitly told not to include identifying information by their ethics committee. Only 1 study sought informed consent from YouTube users. Of 119 articles, 33 (27.7%) contained identifying information about content creators or video commenters, one of which attempted to anonymize direct quotes by not including user information.
CONCLUSIONS
Given the variation in practice, concrete guidelines on research ethics for social media research are needed, especially around anonymizing and seeking consent when using identifying information.

Review
Mucormycosis is a rare, opportunistic, and emerging fungal infection that can rapidly develop into a severe, highly fatal clinical picture. In most cases, it is caused by fungi of the order Mucorales, which are usually avirulent but become pathogenic when the host's immune system is compromised. This systematic review was conducted according to PRISMA guidelines. The databases searched included PubMed, Scopus, and Web of Science. We chose articles that analyzed the oral manifestations of patients with mucormycosis, were published between 2018 and 2023, and met our search terms. The risk of bias in the articles was assessed using the CARE guideline for case reports and STROBE for a cross-sectional study. After the selection process, 20 articles were included in this review, all containing information about the different oral manifestations presented by people with mucormycosis. The most common oral manifestations are mainly bone exposures and oral ulcers, halitosis, pus discharge, gingival thickening, and periodontitis. However, despite the importance of recognizing these oral manifestations in the early stages of mucormycotic infection, providing early treatment, and reducing the high mortality rate of the infection, more studies are needed.

Barriers and facilitators to seeking and accessing mental health support in primary care and the community among female migrants in Europe: a "feminisms" systematic review.
BACKGROUND
Recent years have seen record levels of migration to Europe. Female migrants are at heightened risk of developing mental health disorders, yet they face barriers to accessing mental health services in their host countries. This systematic review aims to summarise the barriers and facilitators to accessing mental health support for female migrants in Europe.
METHODS
The review follows PRISMA guidelines, and the protocol was pre-published on PROSPERO. Six electronic databases were searched: CINAHL, Global Health Database, Medline, PsycARTICLES, PsycINFO and Web of Science. Thematic analysis was undertaken on the identified studies. A feminist quality appraisal tool was applied.
RESULTS
Eight qualitative, six quantitative and five mixed methods studies were identified. Barriers included a lack of information, stigma, religious and cultural practices and beliefs, and a lack of consideration of gender-specific needs within the health system. Gender-sensitive services, supportive general practitioners and religious leaders facilitated access.
CONCLUSIONS
The design of mental health research, services, policies, and commissioning of support for migrants must consider female migrant needs. Mental health support services must be culturally aware and gender sensitive.
REGISTRATION
The review protocol was registered on the International Prospective Register of Systematic Reviews (PROSPERO, registration number CRD42021235571.

Review
BACKGROUND
Mobile apps are fundamental tools in today's society for practical and social endeavors. However, these technologies are often not usable for older users. Given the increased use of mobile apps by this group of users and the impact that certain services may have on their quality of life, such as mobile health, personal finance, or online administrative procedures, a clear set of guidelines for mobile app designers is needed. Existing recommendations for older adults focus on investigations with certain groups of older adults or have not been extracted from experimental results.
OBJECTIVE
In this research work, we systematically reviewed the scientific literature that provided recommendations for the design of mobile apps based on usability testing with older adults and organized such recommendations into a meaningful set of design guidelines.
METHODS
We conducted a systematic literature review of journal and conference articles from 2010 to 2021. We included articles that carried out usability tests with populations aged >60 years and presented transferable guidelines on mobile software design, resulting in a final set of 40 articles. We then carried out a thematic analysis with 3 rounds of analysis to provide meaning to an otherwise diverse set of recommendations. At this stage, we discarded recommendations that were made by just 1 article, were based on a specific mobile app and were therefore nontransferrable, were based on other authors' literature (as opposed to recommendations based on the results of usability tests), or were not sufficiently argued. With the remaining recommendations, we identified commonalities, wrote a faithful statement for each guideline, used a common language for the entire set, and organized the guidelines into categories, thereby giving shape to an otherwise diverse set of recommendations.
RESULTS
Among the 27 resulting guidelines, the rules Simplify and Increase the size and distance between interactive controls were transversal and of the greatest significance. The rest of the guidelines were divided into 5 categories (Help & Training, Navigation, Visual Design, Cognitive Load, and Interaction) and consequent subcategories in Visual Design (Layout, Icons, and Appearance) and Interaction (Input and Output). The recommendations were structured, explained in detail, and illustrated with applied examples extracted from the selected studies, where appropriate. We discussed the design implications of applying these guidelines, contextualized with relevant studies. We also discussed the limitations of the approach followed, stressing the need for further experimentation to gain a better understanding of how older adults use mobile apps and how to better design such apps with these users in mind.
CONCLUSIONS
The compiled guidelines support the design of mobile apps that cater to the needs of older adults because they are based on the results of actual usability tests with users aged >60 years.

INTRODUCTION
Rehabilitation is considered a key intervention in health care. Clinical registries, defined as an organized system that uses observational methods to collect information to assess specific outcomes in a defined population, can contribute to assessing the impact of the rehabilitation intervention. This review aims to identify and describe rehabilitation-specific registry systems with an emphasis on identifying outcomes that enable the assessment of vital areas and activities of daily living.
EVIDENCE ACQUISITION
A systematic scoping review was conducted. A systematic search was conducted up to August 2022 in MEDLINE/PubMed, Embase, Cochrane Library, Epistemonikos, and other search resources. Studies related to rehabilitation registries presented data on people with health problems that could limit their functioning were selected. The inclusion of studies/clinical registries was not limited by methodological design, year of publication, country, or language. The unit of analysis was rehabilitation registries. The measurement instruments used to assess the outcomes were explored to estimate the domain assessed from the vital areas related to functioning and disability as described by the International Classification of Functioning, Disability and Health (ICF). The vital areas were classified according to activities of daily living (ADLs).
EVIDENCE SYNTHESIS
Seventy-one registries in rehabilitation were identified. The registries included a median of 3 (IQR 2-5) assessment instruments designed to assess the impact of different rehabilitation programs. In total, 137 different assessment scales or instruments were identified. Each rehabilitation registry assessed 6 (IQR 2-8) domains of the ICF, and 15.4% of registries assessed all domains. The most assessed domain was "Mobility" (89.7%), and the least assessed was "General Tasks and Demands" (25.6%). In addition, 92.3% of rehabilitation registries assessed basic ADLs, 76.9% advanced ADLs, and 71.8% instrumental ADLs.
CONCLUSIONS
Although clinical registries do not claim to directly assess the impact of rehabilitation programs on people's functioning according to the ICF framework, it was identified that a low percentage of them assessed the nine vital areas through different outcome assessment instruments. However, most rehabilitation registries directly or indirectly assess some basic, instrumental, and advanced ADLs. The findings of this review highlight the need to improve the design of clinical registries focused on assessing the impact of rehabilitation programs to assess people in all areas of their lives.
