Review
BACKGROUND
Quality has been a persistent challenge in the healthcare system, particularly in resource-limited settings. As a result, the utilization of innovative approaches is required to help countries in their efforts to enhance the quality of healthcare. The positive deviance (PD) approach is an innovative approach that can be utilized to improve healthcare quality. The approach assumes that solutions to problems are already available within the community and identifying and sharing those solutions can help others to resolve existing issues. Therefore, this scoping review aimed to synthesize the evidence regarding the use of the PD approach in healthcare system service delivery and quality improvement programs.
METHODS
Articles were retrieved from six international databases. The last date for article search was June 02, 2023, and no date restriction was applied. All articles were assessed for inclusion through a title and/or abstract read. Then, articles that passed the title and abstract review were screened by reading their full texts. In case of duplication, only the full-text published articles were retained. A descriptive mapping and evidence synthesis was done to present data with the guide of the Preferred Reporting Items for Systematic Reviews and Meta-analysis extension for Scoping Reviews checklist and the results are presented in text, table, and figure formats.
RESULTS
A total of 125 articles were included in this scoping review. More than half, 66 (52.8%), of the articles were from the United States, 11(8.8%) from multinational studies, 10 (8%) from Canada, 8 (6.4%) from the United Kingdom and the remaining, 30 (24%) are from other nations around the world. The scoping review indicates that several types of study designs can be applied in utilizing the PD approach for healthcare service and quality improvement programs. However, although validated performance measures are utilized to identify positive deviants (PDs) in many of the articles, some of the selection criteria utilized by authors lack clarity and are subject to potential bias. In addition, several limitations have been mentioned in the articles including issues in operationalizing PD, focus on leaders and senior managers and limited staff involvement, bias, lack of comparison, limited setting, and issues in generalizability/transferability of results from prospects perspective. Nevertheless, the limitations identified are potentially manageable and can be contextually resolved depending on the nature of the study. Furthermore, PD has been successfully employed in healthcare service and quality improvement programs including in increasing surgical care quality, hand hygiene practice, and reducing healthcare-associated infections.
CONCLUSION
The scoping review findings have indicated that healthcare systems have been able to enhance quality, reduce errors, and improve patient outcomes by identifying lessons from those who exhibit exceptional practices and implementing successful strategies in their practice. All the outcomes of PD-based research, however, are dependent on the first step of identifying true PDs. Hence, it is critical that PDs are identified using objective and validated measures of performance as failure to identify true PDs can subsequently lead to failure in identifying best practices for learning and dissemination to other contextually similar settings.

Review
BACKGROUND
Despite significant warnings of adverse effects, antipsychotics continue to be prescribed for managing the behavioural and psychological symptoms of dementia (BPSD) in care homes. Information provided by staff working within care homes is a factor that can influence prescribing decisions in residents with BPSD.
AIM
The review aimed to capture care home staff views towards antipsychotics for residents with BPSD and separately analyse tools utilized in the studies, mapping them onto the theory of planned behaviour (TPB).
METHOD
A comprehensive literature search published in ten databases was conducted between May and July 2020 and updated in July 2021. Studies published in full with no date restriction were included and quality assessed using CROSS checklist. A thematic framework approach was applied to extract data and study tools which were then mapped onto the TPB.
RESULTS
Fourteen studies (2059 participants) were included. Findings identified four overarching themes: attitudes toward antipsychotics (e.g. antipsychotics as an appropriate strategy and effectiveness); barriers to deprescribing (e.g. lower staff education, lack of resources and time, poor medication reviews); measures implemented (e.g. nonpharmacological interventions, medication reviews); and perceived needs of staff (e.g. need for training, financial or clinical support). Identified tools addressed seven but not all components of TPB namely, behavioural, normative and control beliefs, attitude, perceived behavioural control, intention and behaviour.
CONCLUSION
The positive attitudes toward antipsychotics, the identified barriers to deprescribing and the existing tools not addressing all components of the TPB provide the impetus for further research.

Meta-Analysis
Performance of indocyanine green in sentinel lymph node mapping and lymph node metastasis in penile cancer: systematic review, meta-analysis, and single-center experience.
PURPOSE
The aim of this study was to investigate the overall sensitivity and specificity of indocyanine green (ICG)-near-infrared (NIR) fluorescence imaging in the detection of sentinel lymph node metastasis (SLNM) in penile cancer.
METHODS
We searched PubMed, Embase, Web of Science, Scopus, and the Cochrane Library databases to identify manuscripts where ICG was intravenously administered prior to or during penile cancer surgery, with no restriction on language or publication status. The results extracted are presented as forest plots.
RESULTS
Seven studies were included in the analysis. The median sensitivity and specificity of ICG-NIR imaging for SLNM detection were 100 and 4%, respectively; the pooled sensitivity was 100.0% (95% confidence interval [CI] 97.0-100.0) and specificity was 2.0% (95% CI 1.0-3.0). There was no significant difference in the diagnostic results between different injection sites and doses in each experimental group.
CONCLUSION
To our knowledge, this meta-analysis is the first to summarize the diagnostic performance of ICG-NIR imaging for SLNM detection in penile cancer. ICG is sensitive in the imaging of SLN tissue, which can consequently improve the accuracy of lymph node detection. However, the specificity is very low.

Review
With the advancement of spatial analysis approaches, methodological research addressing the technical and statistical issues related to joint spatial and spatiotemporal models has increased. Despite the benefits of spatial modelling of several interrelated outcomes simultaneously, there has been no published systematic review on this topic, specifically when such models would be useful. This systematic review therefore aimed at reviewing health research published using joint spatial and spatiotemporal models. A systematic search of published studies that applied joint spatial and spatiotemporal models was performed using six electronic databases without geographic restriction. A search with the developed search terms yielded 4077 studies, from which 43 studies were included for the systematic review, including 15 studies focused on infectious diseases and 11 on cancer. Most of the studies (81.40%) were performed based on the Bayesian framework. Different joint spatial and spatiotemporal models were applied based on the nature of the data, population size, the incidence of outcomes, and assumptions. This review found that when the outcome is rare or the population is small, joint spatial and spatiotemporal models provide better performance by borrowing strength from related health outcomes which have a higher prevalence. A framework for the design, analysis, and reporting of such studies is also needed.

Non-pharmacological management of hypertension includes weight loss, alcohol and sodium restriction, regular exercise, and relaxation. In people with overweight hypertension, systolic blood pressure (SBP) and diastolic blood pressure (DBP) can be decreased exercise and weight loss together. Breathing exercises are one method of relaxing. The aim of this scoping review is to map the information that is currently available about the advantages of breathing exercises in decreasing blood pressure in hypertension patients. This scoping review adheres to Arksey and O'Malley's framework, which entails identifying review questions, seeking pertinent evidence, choosing pertinent studies, mapping data, and discussing, concluding, and reporting the findings. The PRISMA flowchart is used to show how the evidence search process works. As a result, 339 articles in total were retrieved from the three databases. 20 papers total were included in this review after screening. In 14 of the 20 investigations, participants with stage 1 and stage 2 essential hypertension, two with pre-hypertension, and four with Isolated Systolic Hypertension (ISH) were studied. The respondents' ages ranged from 18 to 75. The systolic blood pressure declined by 4-54.22 mmHg, while the diastolic blood pressure dropped by 3-17 mmHg. Slow breathing can be used as an alternate, non-pharmacological therapy for hypertension individuals to reduce blood pressure. (https://osf.io/ta9u6/).

Review
BACKGROUND
Digital health interventions are efficacious in health-promoting behaviors (eg, healthy eating and regular physical activity) that mitigate health risks and menopausal symptoms in midlife. However, integrated evidence-based knowledge about the mechanisms of change in these interventions is unclear.
OBJECTIVE
This systematic review aimed to evaluate studies on behavior change techniques (BCTs) and mechanisms of change in digital health interventions aimed at promoting health-enhancing behaviors in midlife women (aged 40-65 years).
METHODS
A systematic literature search of the electronic databases PubMed, Web of Science, PsycINFO, and Cochrane Central Register of Controlled Trials in the Cochrane Library was conducted. In total, 2 independent reviewers selected the studies for inclusion, extracted data, and completed BCT mapping of eligible studies. The mechanism of action and intervention functions of eligible studies were evaluated using the behavior change wheel framework. Reporting of psychological theory use within these interventions was explored using the Theory Coding Scheme. Mode of delivery, psychological theory, and BCTs were presented as descriptive statistics.
RESULTS
In total, 13 interventions (including 1315 women) reviewed used 13 (SD 4.30, range 6-21) BCTs per intervention on average. The "Shaping knowledge" and "Repetition and substitution" behavior change categories were used most frequently, with 92% (12/13) of the interventions implementing at least one of the BCTs from these 2 categories. Only 13.98% (169/1209) of the 93 available BCTs were used, with "Instructions on behaviour" most frequently used (12/13, 92%). The behavior change wheel mapping suggests that half of the intervention content aimed to increase "Capability" (49/98, 50% of the intervention strategies), "Motivation" (41/98, 42%), and "Opportunity" (8/98, 8%). "Behavioural Regulation" was the most frequently used mechanism of action (15/98, 15%), followed by increasing "Knowledge" (13/98, 13%) and "Cognitive and Interpersonal skills" (10/98, 10%). A total of 78% (7/9) of the intervention functions were used in the studies to change behavior, primarily through "Enablement" (60/169, 35.5%), whereas no study used "Restriction" or "Modelling" functions. Although 69% (9/13) of the interventions mentioned a psychological theory or model, most (10/13, 77%) stated or suggested rather than demonstrated the use of a theoretical base, and none reported explicit links between all BCTs within the intervention and the targeted theoretical constructs. Technological components were primarily based on web-based (9/13, 69%) modes of delivery, followed by phone or SMS text message (8/13, 62%) and wearables (7/13, 54%).
CONCLUSIONS
The findings of this review indicate an overall weak use of theory, low levels of treatment fidelity, insignificant outcomes, and insufficient description of several interventions to support the assessment of how specific BCTs were activated. Thus, the identified limitations in the current literature provide an opportunity to improve the design of lifestyle health-enhancing interventions for women in midlife.

Review
The bariatric surgery (BS) research landscape is a continuous evolving. Since the first described procedure, numerous different techniques have been developed by surgical teams. In this context, we conducted a systematic mapping of upcoming randomized controlled trials (RCTs) in BS for people with obesity. In June 2021, we performed a systematic review of RCTs evaluating BS versus another surgical procedure or versus a medical control group, through a search in ClinicalTrials.gov. There was no restriction on outcomes for study selection. A total of 62 RCTs were included, totaling 10,800 potential individuals to be included, with planned Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy surgeries the most common. The median number of patients planned to be enrolled is 78 (IQR: 50-143). Mean follow-up time is 12 months in 55% of trials and 4 years or more in 23%. The most frequent (81% of RCTs) outcomes to be investigated are obesity-related diseases with the study of type 2 diabetes, followed by weight loss, quality of life, and surgical complications. The rising number of BS procedures around the world has been followed by a subsequent surge in BS research. An increase in interest is observed in outcomes such as obesity-related diseases, intermediate metabolic markers, quality of life, and body composition.

Review
While research publications on bariatric surgery (BS) have grown significantly over the past decade, there is no mapping of the existing body of evidence on this field of research. We performed a systematic review followed by a mapping of randomized controlled trials (RCTs) in BS for people with obesity. From January 2020 to December 2020, we performed a systematic review of RCTs evaluating BS, versus another surgical procedure, or versus a medical control group, through a search of Embase and PubMed. There was no restriction on outcomes for study selection. A total of 114 RCTs were included, most (73.7%) of which were based on a comparison with Roux-en-Y gastric bypass (RYGB) and conducted between 2010 and 2020. Only 15% of the trials were multicenter and few (3.5%) were international. The median number of patients enrolled was 61 (interquartile range [IQR]: 47.3-100). Follow-up time was 1 to 2 years in 36% and 22.8% of the trials, respectively. Weight loss was the most studied criterion (87% of RCTs), followed by obesity-related diseases, and medical and surgical complications (73%, 54%, and 47% of RCTs, respectively). Nutritional deficiency frequency, body composition, and mental health were little studied (20%, 18% and 5% of RCTs, respectively). Our literature review revealed that much research in BS is wasted because of replication of RCTs on subjects for which there is already body of evidence, with small populations and follow-up times mostly below 2 years. Yet several research questions remain unaddressed, and there are few long-term trials. Future studies should take into account the experience of the past 70 years of research in this field.

Review
A large number of scientific articles have been published regarding impact of COVID-19 infection on dental practice, dental professionals, and the mode of spread of infection via dental procedures. The present systematic review was planned with an aim of evidence mapping and quality analysis of published research on the dental aspects of COVID-19 infection. The protocol was registered at https://share.osf.io/registration/46221-C87-BA8. The search was performed in Scopus, PubMed, Cochrane, and Embase databases till 15th July 2020. There was no restriction of year of publication and language. All types of published articles related to Dentistry, Dentist, Dental practice, and Oral health education on COVID-19 were included. The Joanna Briggs Institute's (JBI) Critical Appraisal Tools were used for the risk of bias analysis of included studies. A total of 393 articles were short-listed and were checked for eligibility and finally, 380 articles were included. Among the 380 research articles published (till July 15, 2020), the majority of the included articles belonged to the lowermost strata of the evidence pyramid. There were 54 original research articles with no randomized clinical trial, systematic review or, meta-analysis pertaining to the dental perspective of COVID-19 infection. The level of available evidence about dentistry and COVID-19 infection is very low with a lack of researches of highest quality. The guidelines/recommendations for dental professionals, proposed by the different scientific organizations/societies regarding COVID-19 infection are only consensus-based necessitating the need to formulate evidence-based guidelines. There is a need to identify essential research questions and strengthen the study designs in most of the aspects related to the dentistry and COVID-19 pandemic.

INTRODUCTION
Different variables, such as repetition and cognitive load, may explain the neurophysiological differences observed from one task to another in motor learning. This learning can be measured with functional magnetic resonance imaging.
AIM
The aim of this systematic review was to document motor learning by functional magnetic resonance imaging during the performance of different simple or complex motor tasks in healthy subjects.
MATERIAL AND METHODS
The search for articles was carried out in the MEDLINE, PEDro, CINHAL and EBSCO databases in May 2020. The systematic review followed the PRISMA criteria.
RESULTS
Nine studies were selected for a qualitative analysis. The quality of the studies ranged from 5 to 7 points on the PEDro scale. The qualitative analysis shows strong evidence that after repeating a motor task a motor learning process is generated. There is both strong and moderate evidence to show that action observation and sleep restriction are involved in motor learning. The results on sensory discrimination training were controversial.
CONCLUSIONS
The results show, with high quality evidence, that repetition of a motor task is associated with the learning process, which seems to be related to a thickening of the motor cortex after the intervention measured with functional magnetic resonance imaging. These results are not conclusive, owing to the limiting factors of this systematic review.
