Meta-Analysis
Food delivers energy, nutrients and a pleasurable experience. Slow eating and prolonged oro-sensory exposure to food during consumption can enhance the processes that promote satiation. This systematic review and meta-analysis investigated the effects of oral processing on subjective measures of appetite (hunger, desire to eat) and objectively measured food intake. The aim was to investigate the influence of oral processing characteristics, specifically "chewing" and "lubrication", on "appetite" and "food intake". A literature search of six databases (Cochrane library, PubMed, Medline, Food Science and Technology Abstracts, Web of Science, Scopus), yielded 12161 articles which were reduced to a set of 40 articles using pre-specified inclusion and exclusion criteria. A further two articles were excluded from the meta-analysis due to missing relevant data. From the remaining 38 papers, detailing 40 unique studies with 70 subgroups, raw data were extracted for meta-analysis (food intake n = 65, hunger n = 22 and desire to eat ratings n = 15) and analyzed using random effects modelling. Oral processing parameters, such as number of chews, eating rate and texture manipulation, appeared to influence food intake markedly but appetite ratings to a lesser extent. Meta-analysis confirmed a significant effect of the direct and indirect aspects of oral processing that were related to chewing on both self-reported hunger (-0.20 effect size, 95% confidence interval CI: -0.30, -0.11), and food intake (-0.28 effect size, 95% CI: -0.36, -0.19). Although lubrication is an important aspect of oral processing, few studies on its effects on appetite have been conducted. Future experiments using standardized approaches should provide a clearer understanding of the role of oral processing, including both chewing and lubrication, in promoting satiety.

Review
OBJECTIVES
While several studies on the preventive and therapeutic effects of prenatal yoga (maternity yoga) have been reported in recent years, there has been no systematic review on the effects of prenatal yoga based on randomized controlled trials (RCT). The purpose of this study, therefore, was to systematically review the literature to clarify the effects of prenatal yoga in RCT focusing on the contents of the intervention, the intervention means, and the frequency of practice.
METHODS
The literature search was performed using the electronic database, PubMed. The inclusion criteria were RCT, pregnant women, and yoga intervention.
RESULTS
In total, 54 citations were found; of these, eight studies (10 reports) were included in the final analysis. In four studies on healthy pregnant women, significant improvement in pain and pleasure at delivery, duration of delivery, perceived stress levels during pregnancy, anxiety levels, depression, pregnancy-related experiences, quality of life, and interpersonal relationships were compared to those in the control group. In two studies on depressed pregnant women, one reported that depression, anxiety levels, anger levels, leg pain, and back pain significantly improved with yoga, while the other found no differences from the control group. In one study of high-risk pregnant women with morbidity factors such as obesity or advanced age, yoga resulted in significantly fewer cases of pregnancy-induced hypertension, gestational diabetes, and intrauterine growth restriction, as well as a decrease in perceived stress levels. In one study on pregnant women with pelvic pain, the median pain score was lower in the yoga group. Regarding the contents of the intervention, while the two studies for depressed pregnant women only included physical postures, the remaining six studies also included breathing technique and meditation. Interventions were performed using lectures by instructors alone or together with self-teaching. The frequency of the intervention varied within each study.
CONCLUSION
The findings suggest that prenatal yoga may help reduce pelvic pain. It may also improve mental condition (stress, depression, anxiety, etc.), physical condition (pain and pleasure at the delivery, etc.), and perinatal outcomes (obstetrical complications, delivery time, etc.). However, further studies are needed. The contents of the intervention, the intervention means, and the frequency varied with each study. Thus, it is necessary to further examine the content of effective interventions, intervention means, and frequency that suit participant's characteristics and each outcome. Further research in this field, particularly randomized controlled trials, is merited.

Pigeons have been considered the most preferred companion for human civilizations since prehistoric times. Despite the fact that pigeons offer the most palatable and nutritious food and provide pleasure to humans, they can pose a health risk because of carrying infectious and zoonotic organisms. Moreover, the scanty of systematic reports on the occurrence of zoonotic pathogens in pigeon makes the situations worst. Hence, the current study conducted a systematic review and meta-analysis to evaluate the global prevalence of zoonotic pathogens among the pigeon population from existing segregated literatures. Four internationally recognized databases including Google Scholar, Scopus, PubMed, and Science Direct were used to search the published studies from January 2000 to October 2021. Analyzing the total 18,589 samples, mean prevalence estimates of pigeon pathogens worldwide were found to be 17% (95% CI:13-21) whereas serological and molecular prevalence were reported as 18% (95% CI:12-23) and 17% (95% CI:10-23). Meanwhile, virus, bacteria, and protozoal pathogens were found to be 21% (10-32%), 17% (12-23%), and 14% (10-19%), respectively. Moreover, continent wise analysis of all zoonotic pigeon pathogens has revealed the highest prevalence rate in Asia 20% (95% CI: 14-26%), followed by Europe 16% (95% CI: 08-24%), Africa 16% (95% CI: 07-24%), and America (North and South) 10% (95% CI: 03-17%). Furthermore, the highest number of studies were reported from Iran showed the prevalence rate of 20%, China 13%, Bangladesh 37%, and Poland 15%. Therefore, this prevalence of data would be helpful to the policymakers to develop appropriate intervention strategies to prevent and control diseases in their respective locations.

BACKGROUND
Everyday technologies, such as laptops and tablets, are often used for enjoyment, pleasure, leisure and social participation. Despite this, whilst considerable research has investigated exploring people's experiences of using assistive technologies, it is not clear how everyday technologies are experienced by individuals living with dementia. The aims of this review were to explore the experiences and views of people living with dementia and carers about using everyday technology to enhance their well-being and enjoyment, social engagement, participation and leisure as well as understand their views about the usability of everyday technology in dementia.
METHODS
A systematic search of the literature was conducted using the electronic databases: PsycINFO, PsycARTICLES, CINAHL Complete and EThOS. Five qualitative studies and five mixed-method studies were included and synthesised using a narrative approach. The methodological quality of the studies was assessed using the National Institute for Health and Care Excellence Qualitative Quality Appraisal, which uncovered key variation in the quality of the included, synthesised studies.
FINDINGS
The review suggests that everyday technologies can help support well-being, particularly when technology is used in a group setting and when individuals received the right amount of support to help engage in the technology. Four major themes relating to experiences and views were derived from the findings of the 10 included studies: 'Technology use maintaining a sense of identity', 'Assumptions held by the self and others', 'The importance of others' and 'The usability of technology influencing effective engagement'.
CONCLUSIONS
Overall, everyday technologies appear to have a positive impact on different aspects of the well-being of people living with dementia. Clinical implications of these findings include supporting opportunities for people living with dementia to use everyday technology for enjoyment and making these technologies more widely available and accessible.

We developed and validated a rating scale to assess the aesthetic pleasure (or beauty) of a visual data representation: the BeauVis scale. With our work we offer researchers and practitioners a simple instrument to compare the visual appearance of different visualizations, unrelated to data or context of use. Our rating scale can, for example, be used to accompany results from controlled experiments or be used as informative data points during in-depth qualitative studies. Given the lack of an aesthetic pleasure scale dedicated to visualizations, researchers have mostly chosen their own terms to study or compare the aesthetic pleasure of visualizations. Yet, many terms are possible and currently no clear guidance on their effectiveness regarding the judgment of aesthetic pleasure exists. To solve this problem, we engaged in a multi-step research process to develop the first validated rating scale specifically for judging the aesthetic pleasure of a visualization (osf.io/fxs76). Our final BeauVis scale consists of five items, "enjoyable," "likable," "pleasing," "nice," and "appealing." Beyond this scale itself, we contribute (a) a systematic review of the terms used in past research to capture aesthetics, (b) an investigation with visualization experts who suggested terms to use for judging the aesthetic pleasure of a visualization, and (c) a confirmatory survey in which we used our terms to study the aesthetic pleasure of a set of 3 visualizations.

Review
Contrasting ethical and legal arguments have been made concerning neonatal male circumcision (NMC) that merit the first systematic review on this topic. We performed PRISMA-compliant keyword searches of PubMed, EMBASE, SCOPUS, LexisNexis, and other databases and identified 61 articles that met the inclusion criteria. In the bibliographies of these articles, we identified 58 more relevant articles and 28 internet items. We found high-quality evidence that NMC is a low-risk procedure that provides immediate and lifetime medical and health benefits and only rarely leads to later adverse effects on sexual function or pleasure. Given this evidence, we conclude that discouraging or denying NMC is unethical from the perspective of the United Nations Convention on the Rights of the Child, which emphasizes the right to health. Further, case law supports the legality of NMC. We found, conversely, that the ethical arguments against NMC rely on distortions of the medical evidence. Thus, NMC, by experienced operators using available safety precautions, appears to be both legal and ethical. Consistent with this conclusion, all of the evidence-based pediatric policies that we reviewed describe NMC as low-risk and beneficial to public health. We calculated that a reduction in NMC in the United States from 80% to 10% would substantially increase the cases of adverse medical conditions. The present findings thus support the evidence-based NMC policy statements and are inconsistent with the non-evidence-based policies that discourage NMC. On balance, the arguments and evidence reviewed here indicate that NMC is a medically beneficial and ethical public health intervention early in life because it reduces suffering, deaths, cases, and costs of treating adverse medical conditions throughout the lifetimes of circumcised individuals.

Meta-Analysis
Pleasantness is generally overlooked when investigating tactile functions. Addition of a pleasant stimulus could allow for a more complete characterisation of somatosensory function. The aims of this review were to systematically assess the methodologies used to elicit a pleasant sensation, measured via psychophysical techniques, and to perform a meta-analysis to measure the effect of brush stroking velocity on touch pleasantness. Eighteen studies were included in the systematic review, with five studies included in the meta-analysis. The review found that factors such as texture, velocity, force, and the duration of continuous stroking influence tactile evoked pleasantness. Specifically, using a soft material and stroking at a velocity of 3 cm/s with light force is generally considered as particularly pleasant. The meta-analysis showed that a brush stroking velocity of 30 cm/s was rated as less pleasant than 3 cm/s, on the forearm. The present study collates the factors that are most likely to provide a stimulus to elicit a pleasant sensation. The results should be important for studies requiring a well-defined pleasant stimulus including neurosensory assessment protocols, allowing for a more complete multimodality assessment of somatosensory function.

Review
BACKGROUND
Anhedonia and amotivation are substantial predictors of poor functional outcomes in people with schizophrenia and often present a formidable barrier to returning to work or building relationships. The Temporal Experience of Pleasure Model proposes constructs which should be considered therapeutic targets for these symptoms in schizophrenia e.g. anticipatory pleasure, memory, executive functions, motivation and behaviours related to the activity. Recent reviews have highlighted the need for a clear evidence base to drive the development of targeted interventions.
OBJECTIVE
To review systematically the empirical evidence for each TEP model component and propose evidence-based therapeutic targets for anhedonia and amotivation in schizophrenia.
METHOD
Following PRISMA guidelines, PubMed and PsycInfo were searched using the terms "schizophrenia" and "anhedonia". Studies were included if they measured anhedonia and participants had a diagnosis of schizophrenia. The methodology, measures and main findings from each study were extracted and critically summarised for each TEP model construct.
RESULTS
80 independent studies were reviewed and executive functions, emotional memory and the translation of motivation into actions are highlighted as key deficits with a strong evidence base in people with schizophrenia. However, there are many relationships that are unclear because the empirical work is limited by over-general tasks and measures.
CONCLUSIONS
Promising methods for research which have more ecological validity include experience sampling and behavioural tasks assessing motivation. Specific adaptations to Cognitive Remediation Therapy, Cognitive Behavioural Therapy and the utilisation of mobile technology to enhance representations and emotional memory are recommended for future development.

Review
INTRODUCTION
Our goal in the current review was to summarize the existing literature on the utility of ecological momentary assessment (EMA) in assessing the social experiences of people with schizophrenia (SZ). We were further interested in examining the associations between EMA-reported social outcomes and traditional assessments of social functioning.
METHODS
We conducted a systematic review of EMA studies published between January 1, 1990 and October 31, 2018 from PubMed and PsycINFO electronic databases. We included EMA studies that assessed social experiences (proportion of time spent alone/with others, affective experiences when with others, social stress, factors related to social experiences) in people with SZ. We included studies that examined associations between laboratory-based, self-report, or clinical assessments of functioning with EMA-reported social experiences.
RESULTS
We identified 22 EMA studies for inclusion in this review. Though heterogeneous in aspects of social experiences assessed, the current literature suggests that people with SZ report more social stress and a preference to be alone when they are with others (nine out of 10 studies). People with SZ report more positive affect when they are with others compared to being alone, and equivalent amounts of positive affect during social experiences as healthy controls (all four studies assessed). Five studies assessed the coherence between functioning assessments and momentary social experiences, with mixed results.
CONCLUSION
We discuss limitations of the literature and future directions. EMA shows promise in assessing more granular aspects of social experience (including social stress and social pleasure) in people with SZ compared to other methods.

UNLABELLED
Sprint interval training (SIT) is characterized by intensity of "all-out" effort and superior time-efficiency compared to traditional moderate-intensity continuous training (MICT) and has been proposed as one viable solution to address the commonly reported barrier of lack of time for physical activity. While substantial physiological benefits of participation in SIT have been well-documented, the psychological responses to SIT are less clear. No systematic review has been conducted thus far to respond to the assumption that its supramaximal intensity will induce adverse feelings. Therefore, the aim of the present study was to synthesize studies analyzing affective and enjoyment responses to SIT and to compare the responses to SIT with MICT and other high intensity interval training (HIIT) protocols with lower intensities. After searching relevant databases up until 22nd March 2021, twenty-five studies meeting the inclusion criteria were included in the present review. Random effect meta-analysis using the pooled data demonstrated that SIT induced similar post-exercise affective valences during the training compared to MICT and HIIT, but lower affective valences immediately post-exercise compared to MICT. Moreover, affective responses during SIT decreased to negative valences according to the results from most included studies, while low-volume SIT protocols with shorter sprint duration and repetitions induced more positive affective responses. Level of enjoyment after SIT were positive and were comparable to MICT or HIIT. Overall, the results from the existing literature indicate that SIT might cause unpleasant feelings during the training and be perceived less pleasurable than MICT immediately post training but could be a comparably enjoyable modality for healthy individuals in relation to MICT or HIIT, despite its supramaximal intensity. Low-volume SIT may be a realistic option for individuals seeking a time-efficient workout with comparable affective responses to MICT or HIIT.
