Addressing implementation considerations when developing universal interventions for speech, language and communication needs in the ordinary classroom: a protocol for a scoping review.

Background: Understanding the factors that influence the implementation of health interventions in the context of education is essential to improving outcomes for children and young people with speech, language and communication needs (SLCN). Yet implementation considerations have not been adequately addressed when developing interventions for this context. The aim of this paper is to present a protocol for a scoping review of existing implementation frameworks that might guide SLCN intervention research in schools. Methods: In accordance with scoping review guidelines, the proposed study will be conducted in phases: (1) identifying potentially relevant studies, (2) screening and selection of studies, (3) charting and extracting data from identified frameworks, (4) collating,summarisingand reporting the results and (5) consulting with stakeholders. Two reviewers will conduct the screening and the data extraction phases independently. Identified frameworks will be collated, and described, and constructs from the frameworks will be categorised using domains from the Consolidated Framework for Implementation Research. A draft implementation science model will be proposed based on the findings of the scoping review. Conclusions: The findings of this review will provide guidance for researchers to begin to address implementation considerations when developing and facilitating the uptake of universal interventions for SLCN in the ordinary classroom, and ultimately can contribute towards improving outcomes for this vulnerable childhood population.

Irisin effects on bone: systematic review with meta-analysis of preclinical studies and prospects for oral health.

Bone quality is an important issue in dentistry. Low bone density may be associated with more severe periodontitis, and may influence implant therapy success. Recent evidence suggests that physical activity can improve alveolar bone quality. Irisin is an exercise-mediated peptide that might be involved in this process. We assessed the effect of exercise and that of intra-peritoneal irisin administration on bone quality in healthy and osteoporosis-induced rodents. This study was registered at PROSPERO (CRD42020184140), and followed PRISMA guidelines. A search by two independent examiners was conducted in five databases and gray literature up to July 2021, without restrictions regarding language or date of publication. Initially, they analyzed retrieved titles and abstracts (n=3,844) based on eligibility criteria. Of this total, 19 studies remained for full-text reading, and 16 proceeded to the data extraction and quality assessment phases. Meta-analyses were conducted (n= 6 studies) to establish the effects of irisin administration on cancellous bone mineral density (BMD). Exercise or irisin administration enhanced bone quality, but the meta-analysis showed that BMD increased only slightly in osteoporotic rodents (BMD: mean difference 0.03 mg/cm3 - 95% CI 0.01-0.05). This indicates that they had no significant benefits on the bones of healthy animals. Implications of key findings evidence the potential of irisin as an agent able to mitigate bone loss caused by osteoporosis, an outcome that could favor dental rehabilitation. More studies investigating the effect of irisin on alveolar bone are needed to elucidate its therapeutic viability and implications.

Algorithms to Preprocess Microarray Image Data.

Microarray is a powerful technology that enables the monitoring of expression levels for thousands of genes simultaneously, providing scientists with a full overview about DNA and RNA investigation. The process is made of three main phases: interaction with biological samples, data extraction, and data analysis. In particular, the data extraction phase strongly relies on image processing algorithms, since the expression levels are revealed by the interaction of light with fluorescent markers. More in detail, in order to extract quantitative information from probes image, three steps are required: (1) gridding, (2) segmentation, and (3) intensity quantification. Errors in one of these steps can deeply affect the process outcome. In this chapter each of the above mentioned steps will be analyzed and discussed. Software platforms dedicated to this purpose will be reported as well.

What evidence exists on the impact of anthropogenic radiofrequency electromagnetic fields on animals and plants in the environment? A systematic map protocol

BackgroundExposure to radiofrequency (RF) electromagnetic fields (EMF), particularly from telecommunications sources, is one of the most common and fastest growing anthropogenic factors on the environment. In many countries, humans are protected from excessive RF EMF exposure by safety standards that are based on guidelines by the International Commission on Non-Ionizing Radiation Protection (ICNIRP). The ICNIRP guidelines are based on knowledge of how RF EMF affects the human body, however, there are currently no recognised international guidelines to specifically protect animals and plants. Whether the ICNIRP guidelines for humans is adequate to provide protection to the environment is a subject of active debate. This systematic map will collate all the available evidence on whether anthropogenic RF EMF has a negative effect on plants and animals in the environment. The map will also identify gaps in knowledge, recommend future research and inform environmental and radiation protection authorities.MethodsThe proposed systematic map will include peer-reviewed and grey literature published in English. The EMF—Portal, PubMed and Web of Science databases will be searched using a search string prepared by the review team and tested for comprehensiveness against a list of known relevant reviews. Once duplicates are removed, retrieved articles will be screened in three stages: title, abstract, and full text. Studies will be selected with a subject population of all plants and animals, with exposures to anthropogenic RF EMF (frequency range 100 kHz–300 GHz) compared to no or lower-level exposure, and for all outcomes related to the studied populations. Kappa statistic tests will be conducted at each stage to ensure consistency of decision-making regarding the predefined inclusion/exclusion criteria. Eligible studies will then proceed to the data extraction phase, which will extract meta-data such as bibliographic information, taxonomic information, RF EMF exposure data, outcome(s), sample size, etc. The extracted data will then be organised into a systematic map and the findings summarised by cross-tabulating key meta-data variables in heat maps, charts or other data visualization methods. The systematic map will identify gaps in knowledge, priorities for future research and potential subtopics for further analysis and/or systematic review.

Ozanimod: A First-in-Class Sphingosine 1-Phosphate Receptor Modulator for the Treatment of Ulcerative Colitis.

To review the pharmacological and clinical profile of ozanimod in the treatment of ulcerative colitis (UC). A PubMed search was conducted from inception to July 2021 using the keywords ozanimod, ulcerative colitis, and sphingosine 1-phosphate receptor modulator. Information was also extracted from published abstracts and the package insert. Phase 2 and 3 studies and relevant literature on ozanimod pharmacological and clinical profiles were reviewed. Ozanimod approval was based on True North, a phase 3 trial evaluating ozanimod's efficacy and safety in the treatment of moderate to severe UC. Compared with placebo, ozanimod led to clinical remission in a significantly higher proportion of patients in both the induction and maintenance phase. Additionally, for secondary end points of clinical response, endoscopic improvement, corticosteroid-free remission, and mucosal healing, ozanimod performed significantly better than placebo. Common adverse events included infections, headaches, hypertension, bradycardia, and liver enzyme elevations. Ozanimod is the first sphingosine 1-phosphate modulator to be approved for UC and is administered orally. Its efficacy profile is comparable with other UC medications. However, its safety profile is unique, requiring extensive assessments prior to initiation of and during treatment. Thus, it is unclear how ozanimod will be positioned in UC treatment. Ozanimod is another option in the growing arsenal of UC treatment. Although it offers a novel mechanism of action and is administered orally, there are important safety, dosing, and pharmacokinetic factors to consider prior to initiation and use.

1% Tirbanibulin Ointment for the Treatment of Actinic Keratoses.

ObjectiveActinic keratoses (AKs) are cutaneous lesions that arise in sun-damaged skin. AKs may transform into squamous cell carcinoma in situ. Tirbanibulin 1% ointment is a new topical treatment for AKs, recently approved by the Food and Drug Administration.Data SourcesThe PubMed database was searched for articles published from 1960 to March 31, 2021, using the keywords tirbanibulin and Klisyri.Data ExtractionPhase 2 and phase 3 clinical trials were reviewed.Data SynthesisIn phase 2 clinical trials, 43% of patients treated with tirbanibulin experienced complete clearance by day 57 (43% [95% CI = 32, 54]). Across two phase 3 clinical trials (pooled data), complete (100%) clearance occurred in 49% of patients in tirbanibulin groups and in only 9% of the vehicle groups (difference, 41% points; 95% CI = 35 to 47; P < 0.001). Although no comparative studies are available, tirbanibulin is applied for a shorter duration (5 days) compared with diclofenac 3% gel, fluorouracil 5% cream, and imiquimod 3.75% cream. Adverse events were mild and included pruritus, application site pain, and local skin reactions. Systemic adverse events such as necrosis and angioedema, observed with other AK treatments such as fluorouracil and imiquimod, were not observed with tirbanibulin, thus giving tirbanibulin a favorable safety profile.Relevance to Patient Care and Clinical PracticeTirbanibulin effectively reduces AK burden and recurrence and has a favorable safety profile with mild adverse events. In comparison, imiquimod, 5-flourouracil, and diclofenac can result in necrosis, angioedema, and arthralgias.ConclusionWith a favorable safety profile and short regimen, tirbanibulin is an efficacious treatment for clinicians to utilize in their treatment toolbox when treating AKs on the face and scalp.

Reversible Data Hiding in Encrypted Image Based on (7, 4) Hamming Code and UnitSmooth Detection.

With the development of cloud storage and privacy protection, reversible data hiding in encrypted images (RDHEI) plays the dual role of privacy protection and secret information transmission. RDHEI has a good application prospect and practical value. The current RDHEI algorithms still have room for improvement in terms of hiding capacity, security and separability. Based on (7, 4) Hamming Code and our proposed prediction/ detection functions, this paper proposes a Hamming Code and UnitSmooth detection based RDHEI scheme, called HUD-RDHEI scheme for short. To prove our performance, two database sets—BOWS-2 and BOSSBase—have been used in the experiments, and peak signal to noise ratio (PSNR) and pure embedding rate (ER) are served as criteria to evaluate the performance on image quality and hiding capacity. Experimental results confirm that the average pure ER with our proposed scheme is up to 2.556 bpp and 2.530 bpp under BOSSBase and BOWS-2, respectively. At the same time, security and separability is guaranteed. Moreover, there are no incorrect extracted bits during data extraction phase and the visual quality of directly decrypted image is exactly the same as the cover image.

A Sentence Classification Framework to Identify Geometric Errors in Radiation Therapy from Relevant Literature

The objective of systematic reviews is to address a research question by summarizing relevant studies following a detailed, comprehensive, and transparent plan and search protocol to reduce bias. Systematic reviews are very useful in the biomedical and healthcare domain; however, the data extraction phase of the systematic review process necessitates substantive expertise and is labour-intensive and time-consuming. The aim of this work is to partially automate the process of building systematic radiotherapy treatment literature reviews by summarizing the required data elements of geometric errors of radiotherapy from relevant literature using machine learning and natural language processing (NLP) approaches. A framework is developed in this study that initially builds a training corpus by extracting sentences containing different types of geometric errors of radiotherapy from relevant publications. The publications are retrieved from PubMed following a given set of rules defined by a domain expert. Subsequently, the method develops a training corpus by extracting relevant sentences using a sentence similarity measure. A support vector machine (SVM) classifier is then trained on this training corpus to extract the sentences from new publications which contain relevant geometric errors. To demonstrate the proposed approach, we have used 60 publications containing geometric errors in radiotherapy to automatically extract the sentences stating the mean and standard deviation of different types of errors between planned and executed radiotherapy. The experimental results show that the recall and precision of the proposed framework are, respectively, 97% and 72%. The results clearly show that the framework is able to extract almost all sentences containing required data of geometric errors.

Dual encoding approach with sequence folding for reversible data hiding in dual stego images

This paper proposes a dual encoding approach with sequence folding for reversible data hiding in dual stego images. This method initially encodes the secret data by creating two encoding tables that contain index as well as code sequence based on message intensities and the two encoding tables are updated. The code sequence in the second encoding table is folded if the preceding half or succeeding half of the two encoding tables gets matched. The folding is also done if the maximum intensity in the code of two encoding tables lies in the most succeeding end. The same encoding process is repeated for all message intensities. After encoding the message intensities, the encoded indices are embedded on the cover image to obtain the dual stego images. In the data extraction phase, the encoded indices are initially extracted and is decoded by using the dual decoding table. The behavior of the proposed data hiding is evaluated using the metrics such as embedding capacity, embedding rate, PSNR, and SSIM using the standard test images. Experimental verification reveals that the proposed data hiding algorithm shows outstanding performance when compared to the traditional dual stego based data hiding methods.

Experiences of outdoor nature-based therapeutic recreation programs for persons with a mental illness: a qualitative systematic review.

The objective of this review was to identify, appraise, and synthesize the best available evidence related to participation in outdoor nature-based therapeutic recreation programs for adults with a mental illness living in the community. Therapeutic recreation is posited to be beneficial for persons living with a mental illness. Research evidence indicates that therapeutic recreation programs can foster mental health recovery. It is important to understand the effectiveness of this from the perspective of persons living with mental illness how outdoor nature-based therapeutic recreation programs are meaningful and helpful for recovery. This review considered studies that collected qualitative data on the experiences and perspectives of adults with a mental illness regarding their participation in outdoor nature-based therapeutic recreation programs. The databases PsycINFO, CINAHL, MEDLINE, Scopus, and Informit, as well as unpublished sources in gray literature (Google Scholar, OpenGrey), were searched and reference lists were checked to locate any additional studies. Studies published in English were considered, with a date range from inception to 2019. Three reviewers independently assessed the methodological quality of the studies that met the inclusion criteria using the JBI critical appraisal approach for qualitative research. Data were extracted by one reviewer using the standardized qualitative extraction tool and checked for accuracy by three other reviewers. The qualitative research findings were pooled using JBI methodology. The JBI process of meta-aggregation was used to identify categories and synthesized findings, and a level of confidence was assigned to both synthesized findings. Eighteen papers met the inclusion criteria and were included in the data extraction phase. A total of 84 findings were extracted and aggregated into six categories based on similarity of meaning and two synthesized findings. The methodological quality of the studies varied, and the overall level of confidence of the synthesized findings was determined to be moderate. This review identified that persons living with mental illness perceive outdoor nature-based therapeutic recreation as enjoyable and that therapeutic recreation makes a positive contribution to mental health. Congruent with the literature, therapeutic recreation offers a socially inclusive and psychologically safe environment. The intentionally structured social milieu enhances the formation of social relationships and meaningful connections for persons with mental illness. Elements linked with psychological well-being, such as intrinsic motivation, overcoming perceived challenges, and finding purpose and meaning, are enhanced through participation in therapeutic recreation in outdoor nature-based settings. Increased levels of physical activity, greater self-esteem, and enhanced sense of identity were some of the perceived positive changes. This review provides important insights into the subjective needs of persons with mental illness who undertake therapeutic recreation in outdoor nature-based settings. The qualitative findings can inform health care providers, or those interested in therapeutic recreation programming, to use alongside quantitative evidence of effectiveness to design nature-based therapeutic recreation activities that are meaningful for persons with mental illness. Limitations of the research were that papers published in languages other than English were not searched, and papers not located may have influenced the findings of this review.

Mental health ubiquitous monitoring supported by social situation awareness: A systematic review.

Traditionally, the process of monitoring and evaluating social behavior related to mental health has based on self-reported information, which is limited by the subjective character of responses and various cognitive biases. Today, however, there is a growing amount of studies that have provided methods to objectively monitor social behavior through ubiquitous devices and have used this information to support mental health services. In this paper, we present a Systematic Literature Review (SLR) to identify, analyze and characterize the state of the art about the use of ubiquitous devices to monitor users' social behavior focused on mental health. For this purpose, we performed an exhaustive literature search on the six main digital libraries. A screening process was conducted on 160 peer-reviewed publications by applying suitable selection criteria to define the appropriate studies to the scope of this SLR. Next, 20 selected studies were forwarded to the data extraction phase. From an analysis of the selected studies, we recognized the types of social situations identified, the process of transforming contextual data into social situations, the use of social situation awareness to support mental health monitoring, and the methods used to evaluate proposed solutions. Additionally, we identified the main trends presented by this research area, as well as open questions and perspectives for future research. Results of this SLR showed that social situation-aware ubiquitous systems represent promising assistance tools for patients and mental health professionals. However, studies still present limitations in methodological rigor and restrictions in experiments, and solutions proposed by them have limitations to be overcome.

A general framework for partial reversible data hiding using hamming code

A general framework for partial reversible data hiding is proposed in this paper. The original image is adjusted to form a cover image in image transferring phase. The minimal square error criterion between Hamming codeword and the bits from the original image is adopted to generate the cover image. After image transformation, some bits in the cover image are actually a Hamming codeword. In data embedding phase, the secret bits are concealed into the cover image to generate a stego image. The secret messages can be extracted from the stego image, and the stego image can be recovered back to cover image in data extraction and image restoration phase. The so-called partial reversible property indicates an almost distortion-free original image (e.g., cover image) can be obtained. Theoretical analysis on the embedding capacity and visual performance by the proposed method is given. Further, experimental and theoretical results are demonstrated to show the feasibility and advantages of the proposed method.

Surgical Practice in the Shadow of COVID-19 Outbreak.

COVID-19 epidemic rapidly spread all around the world with over 1500 thousand infected cases and 95000 deaths. This rapid pandemic may overwhelm health care capacity and shortage of resources is a major concern. Literature provided guidelines on management of COVID-19 patients but healthcare service to the normal population should be continued meanwhile. Health system should act immediately and wisely to support essential surgical care while fighting against COVID-19. We conducted a comprehensive search in the major data bases since 2020, using the combination of MeSH words of "COVID-19 " and "surgery" and finally 34 full texts entered to data extraction phase to define a plan for surgical practice during COVID-19 pandemic. Healthcare workers are at the higher risk of contamination by COVID-19 especially in early stage of outbreak when they were not aware of the different aspects of COVID-19 pandemic. All healthcare staff must be trained to properly use PPE. All patients have to be screened at the hospital triage. All elective surgical interventions must be postponed. Operation room is considered as a place with high risk of cross infection so the highest level of protection should be maintained. Anesthesia, endoscopy and oral surgery are considered as aerosol producing procedures with very high risk of contamination. There is not any evidence to support the risk of infection trough blood products. Postoperative respiratory problems are more common among COVID-19 patients that may increases the estimated risk of morbidity and mortality. COVID-19 pandemic is a dynamic challenge for health system to save the healthcare staff and equipment resources by timely decisions. Healthcare workers are at the higher risk of contamination by COVID-19 especially in early phase of epidemic when the protection is sub-optimal.

What is the nature and extent of evidence on methodologies for monitoring and evaluating marine spatial management measures in UK and similar coastal waters? A systematic map protocol

BackgroundAnthropogenic degradation of marine ecosystems is widely accepted as a major social-ecological problem. The growing urgency to better manage marine ecosystems has led to the increasing application of ‘spatial management measures’ including marine protected areas, sectoral (e.g. fishery) closures, and marine spatial planning. However, the designation of varied spatial management regimes is just the first step; achievement of objectives relies upon effective implementation, monitoring, evaluation and adaptation. Despite spatial management being a core component of the marine management portfolio, to our knowledge, there is no systematic overview of the evidence on methodologies available, and employed, to monitor and evaluate their effectiveness across social, economic and ecological outcomes.MethodsThis systematic map will examine existing evidence describing methodologies for monitoring the effects, and evaluating the effectiveness, of marine spatial management across ecological, social and economic outcomes. Our aim is to provide a resource for decision-makers, primarily in the UK but also internationally, that supports effective marine management, and to describe the current evidence base. Identification and evaluation of relevant studies will therefore be restricted to coastal countries identified by our Stakeholder Group as being relevant to the UK, and searches will be restricted to the period 2009 to 2019 to align with the current UK policy context. Searches for relevant grey and academic literature, published in English, will be conducted in four bibliographic search engines, Google Scholar, 38 organisational websites and one specialist data repository. Eligibility screening will be conducted first at title and abstract level, and then at full text. Coding and meta-data extraction from eligible studies will include: bibliographic information, general information about the spatial management measure studied, and methodological information on the monitoring and evaluation undertaken. Consistency checking amongst reviewers will be undertaken during screening, coding and data extraction phases. The outcome of the systematic map will be a database that displays the meta-data of identified relevant studies. Findings will be presented in a descriptive report detailing the evaluation approaches and analytical methodologies employed, and data collection methods applied and/or data required by relevant studies to inform evaluations on the effectiveness of marine spatial management measures.

Reversible Steganographic Scheme for AMBTC-Compressed Image Based on (7,4) Hamming Code

In recent years, compression steganography technology has attracted the attention of many scholars. Among all image compression method, absolute moment block truncation coding (AMBTC) is a simple and effective compression method. Most AMBTC-based reversible data hiding (RDH) schemes do not guarantee that the stego AMBTC compression codes can be translated by the conventional AMBTC decoder. In other words, they do not belong to Type I AMBTC-based RDH scheme and easily attract malicious users’ attention. To solve this problem and enhance the hiding capacity, we used (7,4) hamming code to design a Type I AMBTC-based RDH scheme in this paper. To provide the reversibility feature, we designed a prediction method and judgement mechanism to successfully select the embeddable blocks during the data embedding phase and data extraction and recovery phase. In comparing our approach with other BTC-based schemes, it is confirmed that our hiding capacity is increased while maintaining the limited size of the compression codes and acceptable image quality of the stego AMBTC-compressed images.
