The role of human involvement and support in digital mental health interventions for people with schizophrenia spectrum disorders: a critical review.

Schizophrenia spectrum disorders (SDD) are characterized by a complex array of psychosis symptoms, and typically require ongoing and long-term support, including pharmacological and nonpharmacological management. Digital mental health interventions (DMHIs) have been suggested as a novel therapeutic approach to enable low-cost, scalable improvements in quality of care for adults living with SSD. However, the types and role of human involvement and support within DMHIs is currently unknown. Several recent systematic reviews and meta-analyses have investigated the potential efficacy of DMHIs for people with SSD, with scant yet emerging systematic evidence on the effects of human support within DMHIs on mental health outcomes. Further, several recent individual studies examined the efficacy of DMHIs with human support among people with SSD and provided valuable insights into the potential key elements of such support on outcomes relevant to this population. The current critical review provides the first narrative synthesis of available evidence to guide clinicians and intervention develops in designing DMHIs with adequate human support that may enhance long-term outcomes of people living with SSD.

Practices and Barriers in Developing and Disseminating Plain-Language Resources Reporting Medical Research Information: A Scoping Review.

The intent of plain-language resources (PLRs) reporting medical research information is to advance health literacy among the general public and enable them to participate in shared decision-making (SDM). Regulatory mandates coupled with academic and industry initiatives have given rise to an increasing volume of PLRs summarizing medical research information. However, there is significant variability in the quality, format, readability, and dissemination channels for PLRs. In this scoping review, we identify current practices, guidance, and barriers in developing and disseminating PLRs reporting medical research information to the general public including patients and caregivers. We also report on the PLR preferences of these intended audiences. A literature search of three bibliographic databases (PubMed, EMBASE, Web of Science) and three clinical trial registries (NIH, EMA, ISRCTN registry) was performed. Snowball searches within reference lists of primary articles were added. Articles with PLRs or reporting topics related to PLRs use and development available between January 2017 and June 2023 were identified. Evidence mapping and synthesis were used to make qualitative observations. Identified PLRs were quantitatively assessed, including temporal annual trends, availability by field of medicine, language, and publisher types. A total of 9116 PLRs were identified, 9041 from the databases and 75 from clinical trial registries. The final analysis included 6590 PLRs from databases and 72 from registries. Reported barriers to PLR development included ambiguity in guidance, lack of incentives, and concerns of researchers writing for the general public. Available guidance recommendations called for greater dissemination, increased readability, and varied content formats. Patients preferred visual PLRs formats (e.g., videos, comics), which were easy to access on the internet and used short jargon-free text. In some instances, older audiences and more educated readers preferred text-only PLRs. Preferences among the general public were mostly similar to those of patients. Psychology, followed by oncology, showed the highest number of PLRs, predominantly from academia-sponsored research. Text-only PLRs were most commonly available, while graphical, digital, or online formats were less available. Preferred dissemination channels included paywall-free journal websites, indexing on PubMed, third-party websites, via email to research participants, and social media. This scoping review maps current practices, recommendations, and patients' and the general public's preferences for PLR development and dissemination. The results suggest that making PLRs available to a wider audience by improving nomenclature, accessibility, and providing translations may contribute to empowerment and SDM. Minimizing variability among available guidance for PLR development may play an important role in amplifying the value and impact of these resources.

Muscle synergies in upper limb stroke rehabilitation: a scoping review.

Upper limb impairment is a common consequence of stroke, significantly affecting the quality of life and independence of survivors. This scoping review assesses the emerging field of muscle synergy analysis in enhancing upper limb rehabilitation, focusing on the comparison of various methodologies and their outcomes. It aims to standardize these approaches to improve the effectiveness of rehabilitation interventions and drive future research in the domain. Studies included in this scoping review focused on the analysis of muscle synergies during longitudinal rehabilitation of stroke survivors' upper limbs. A systematic literature search was conducted using PubMed, Scopus, and Web of Science databases, until September 2023, and was guided by the PRISMA for scoping review framework. Fourteen studies involving a total of 247 stroke patients were reviewed, featuring varied patient populations and rehabilitative interventions. Protocols differed among studies, with some utilizing robotic assistance and others relying on traditional therapy methods. Muscle synergy extraction was predominantly conducted using Non-Negative Matrix Factorization from electromyography data, focusing on key upper limb muscles essential for shoulder, elbow, and wrist rehabilitation. A notable observation across the studies was the heterogeneity in findings, particularly in the changes observed in the number, weightings, and temporal coefficients of muscle synergies. The studies indicated varied and complex relationships between muscle synergy variations and clinical outcomes. This diversity underscored the complexity involved in interpreting muscle coordination in the stroke population. The variability in results was also influenced by differing methodologies in muscle synergy analysis, highlighting a need for more standardized approaches to improve future research comparability and consistency. The synthesis of evidence presented in this scoping review highlights the promising role of muscle synergy analysis as an indicator of motor control recovery in stroke rehabilitation. By offering a comprehensive overview of the current state of research and advocating for harmonized methodological practices in future longitudinal studies, this scoping review aspires to advance the field of upper limb rehabilitation, ensuring that post-stroke interventions are both scientifically grounded and optimally beneficial for patients.

Clinical and cost-effectiveness of clopidogrel resistance genotype testing after ischaemic stroke or transient ischaemic attack: a systematic review and economic model.

Stroke or transient ischaemic attack patients are at increased risk of secondary vascular events. Antiplatelet medications, most commonly clopidogrel, are prescribed to reduce this risk. Factors including CYP2C19 genetic variants can hinder clopidogrel metabolism. Laboratory-based or point-of-care tests can detect these variants, enabling targeted treatment. To assess the effectiveness of genetic testing to identify clopidogrel resistance in people with ischaemic stroke or transient ischaemic attack. Specific objectives: Do people tested for clopidogrel resistance, and treated accordingly, have a reduced risk of secondary vascular events? Do people with loss-of-function alleles associated with clopidogrel resistance have a reduced risk of secondary vascular events if treated with alternative interventions compared to clopidogrel? Do people with loss-of-function alleles associated with clopidogrel resistance have an increased risk of secondary vascular events when treated with clopidogrel? What is the accuracy of point-of-care tests for detecting variants associated with clopidogrel resistance? What is the technical performance and cost of CYP2C19 genetic tests? Is genetic testing for clopidogrel resistance cost-effective compared with no testing? Systematic review and economic model. Objective 1: Two studies assessed secondary vascular events in patients tested for loss-of-function alleles and treated accordingly. They found a reduced risk, but confidence intervals were wide (hazard ratio 0.50, 95% confidence interval 0.09 to 2.74 and hazard ratio 0.53, 95% confidence interval 0.24 to 1.18). Objective 2: Seven randomised controlled trials compared clopidogrel with alternative treatment in people with genetic variants. Ticagrelor was associated with a lower risk of secondary vascular events than clopidogrel (summary hazard ratio 0.76, 95% confidence interval 0.65 to 0.90; two studies). Objective 3: Twenty-five studies compared outcomes in people with and without genetic variants treated with clopidogrel. People with genetic variants were at an increased risk of secondary vascular events (hazard ratio 1.72, 95% confidence interval 1.43 to 2.08; 18 studies). There was no difference in bleeding risk (hazard ratio 0.98, 95% confidence interval 0.68 to 1.40; five studies). Objective 4: Eleven studies evaluated Genomadix Cube accuracy; no studies evaluated Genedrive. Summary sensitivity and specificity against laboratory reference standards were both 100% (95% confidence interval 94% to 100% and 99% to 100%). Objective 5: Seventeen studies evaluated technical performance of point-of-care tests. Test failure rate ranged from 0.4% to 19% for Genomadix Cube. A survey of 8/10 genomic laboratory hubs revealed variation in preferred technologies for testing, and cost per test ranging from £15 to £250. Most laboratories expected test failure rate to be < 1%. Additional resources could enhance testing capacity and expedite turnaround times. Objective 6: Laboratory and point-of-care CYP2C19 testing strategies were cost-saving and increase quality-adjusted life-years compared with no testing. Both strategies gave similar costs, quality-adjusted life-years and expected net monetary benefit. Our results suggest that CYP2C19 testing followed by tailored treatment is likely to be effective and cost-effective in both populations. Accuracy and technical performance of Genedrive. Test failure rate of Genomadix Cube in a NationalHealthServicesetting. Value of testing additional loss-of-function alleles. Appropriateness of treatment dichotomy based on loss-of-function alleles. Lack of data on Genedrive. No randomised 'test-and-treat' studies of dipyramidole plus aspirin. This study is registered as PROSPERO CRD42022357661.

Antimicrobial resistance among migrants in Europe: a systematic review and meta-analysis – update from 2017 to 2023

Antimicrobial resistance (AMR) is a critical global health concern. A previous systematic review showed that migrants in Europe are at increased risk of AMR. Since the COVID-19 pandemic there have been rapid changes in patterns of antibiotic use, AMR, and migration. We aimed to present an updated evidence synthesis on the current distribution of AMR among migrants in Europe. We carried out a systematic review and meta-analysis in accordance with PRISMA guidelines (PROSPERO ID: CRD42022343263). We searched databases (MEDLINE, Embase, PubMed and Scopus) from 18 January 2017 until 18 January 2023 to identify primary data from observational studies reporting any laboratory-confirmed AMR among migrants in the European Economic Area (EEA) and European Union-15 (EU-15) countries using over 7 key search terms for migrants and over 70 terms for AMR and countries in Europe. Outcomes were infection with, or colonisation of AMR bacteria. Methodological quality was assessed using Joanna Briggs Institute Critical Appraisal Checklist for Observational Studies. We meta-analysed the pooled-prevalence of infection and/or colonisation of AMR organisms. Among 630 articles, 21 observational studies met the inclusion criteria and were included in this review. The pooled prevalence for any detected AMR was 28.0% (95% CI 18.0%-41.0%, I 2 =100%) compared to a 25.4% seen in the previous review; gram-negative bacteria 31.0% (95% CI 20.0%-44.0%, I 2 =100%), and methicillin-resistant staphylococcus aureus 10.0% (95% CI 5.0%-16.0%, I 2 =99%). Drug-resistant bacteria were more prevalent in community settings in large migrant populations (pooled prevalence: 41.0%, 95% CI 24.0%-60.0%, I 2 =99%) than in hospitals (21.0%, 95% CI 12.0%-32.0%, I 2 =99%). AMR estimates in 'other' migrants were 32.0%, (95% CI 12.0%-57.0%, I 2 =100%) and 28.0% (95% CI 18.0%-38.0%, I 2=100%) in forced migrants. No firm evidence of AMR acquisition with arrival time or length of stay in the host country was found. Studies investigating AMR in migrants are highly heterogenous. However, since the COVID-19 pandemic, migrants may be at higher risk of acquiring resistant bacteria, particularly gram-negative bacteria, within community settings such as refugee camps and detention centres in Europe. Our study highlights the importance of infrastructure and hygiene measures within these settings, to mitigate transmission of resistant pathogens. Policy-makers should screen for AMR in migrants prior to departure from countries of origin, where feasible, and upon arrival to a new country to ensure optimal health screening, infection control and effective treatment. There was no funding source for this study.

Ultra-processed foods, allergy outcomes and underlying mechanisms in children: An EAACI task force report.

Consumption of ultra-processed foods [UPFs] may be associated with negative health outcomes. Limited data exist regarding the potential role of UPFs in the occurrence of allergic diseases. The underlying mechanisms underpinning any such associations are also poorly elucidated. We performed a systematic review and narrative evidence synthesis of the available literature to assess associations between UPF consumption and pediatric allergy outcomes (n = 26 papers), including data on the association seen with the gut microbiome (n = 16 papers) or immune system (n = 3 papers) structure and function following PRISMA guidelines. Dietary exposure to fructose, carbonated soft drinks, and sugar intake was associated with an increased risk of asthma, allergic rhinitis, and food allergies in children. Commercial baby food intake was associated with childhood food allergy. Childhood intake of fructose, fruit juices, sugar-sweetened beverages, high carbohydrate UPFs, monosodium glutamate, UPFs, and advanced glycated end-products (AGEs) was associated with the occurrence of allergic diseases. Exposure to UPFs and common ingredients in UPFs seem to be associated with increased occurrence of allergic diseases such as asthma, wheezing, food allergies, atopic dermatitis, and allergic rhinitis, in many, but not all studies. More preclinical and clinical studies are required to better define the link between UPF consumption and the risk of allergies and asthma. These observational studies ideally require supporting data with clearly defined UPF consumption, validated dietary measures, and mechanistic assessments to definitively link UPFs with the risk of allergies and asthma.

Mirtazapine in pregnancy and lactation: A systematic review of adverse outcomes.

Peripartum depression is common and treatment with mirtazapine may be indicated. However, evidence on its safety in pregnancy and lactation is fragmented. The objective of this systematic review was to evaluate the literature on the safety of mirtazapine in pregnancy and lactation. PubMed, Embase, Medline, PsycInfo, and clinicaltrials.gov were searched for 'antidepressants' or 'mirtazapine' in combination with 'pregnancy', 'lactation' or 'offspring'. No restrictions on type of study were applied and selection was performed by two independent reviewers using Covidence. Two reviewers extracted data and performed risk of bias assessment and evidence synthesis was performed for each outcome individually. The protocol was registered at PROSPERO (registration number CRD42021275127). The initial search yielded 15,380 articles after removal of duplicates. After screening based on title and abstract, 431 articles remained for full text review. Of these, 41 studies were included (15 cohort studies, one case-control study, 11 case series, and 14 case reports). In most studies, the outcomes in mirtazapine-exposed pregnancies were comparable to controls. However, results on congenital malformations and spontaneous abortion were conflicting. Neonatal adaptation syndrome was reported after mirtazapine exposure in late pregnancy. Data on mirtazapine exposure during lactation were scarce. We identified no substantial evidence indicating that mirtazapine exposure is associated with adverse outcomes in pregnancy or in offspring, other than neonatal adaptation syndrome. However, overall quality of evidence was low, and results on congenital malformations and spontaneous abortions were conflicting. Data on mirtazapine exposure through breastfeeding were limited and did not allow for conclusions.

Lifespan of COVID‐19 living guideline recommendations: A survival analysis

AbstractBackgroundNICE has maintained a portfolio of coronavirus disease 2019 (COVID‐19) living guidelines since March 2020. Recommendations within these living guidelines are subject to continuous surveillance and updates in response to triggers. However, the lifespan of individual living guideline recommendations and features that may impact whether a recommendation becomes out of date sooner is unknown.ObjectivesThis study describes the length of time NICE COVID‐19 living guideline recommendations have remained valid.MethodsAll guidelines within NICE's COVID‐19 portfolio were included to determine the lifespan of living guideline recommendations. Data were collected on all recommendations that had been developed, undergone surveillance or updated between 1 March 2020 and 31 August 2022. The initial publication date, decision to update and updated publication date were extracted. Updates were labelled as major changes in evidence synthesis or minor changes without a substantial change in the evidence base. Any recommendation that had not been updated or withdrawn was censored. Survival analysis (Kaplan–Meier curve) was carried out to determine the lifespan of recommendations.ResultsOverall, 26 COVID‐19 living guidelines and 1182 recommendations were included in the analysis. Living recommendations had a median survival time of 739 days (interquartile range [IQR]: 332, 781). Based on recommendation type, intervention recommendations had a shorter survival time (354 days, IQR: 312, 775) compared to diagnosis (368 days, IQR: 328, 795), patient experience (733 days, IQR: 345, 795) and service delivery (739 days, IQR: 643, 781). Within intervention type, pharmacological recommendations had the shortest survival time versus nonpharmacological recommendations (335 days, IQR: 161, 775 vs. 775 days, IQR: 354, 775). Updates were published an average of 29.12 days following a surveillance decision.ConclusionWithin living guidelines, some recommendations need to be updated sooner than others. This study outlines the value of a flexible responsive approach to surveillance according to the pace of change and expectation of update triggers.

Prevalence of cerebral visual impairment in developmental and Epileptic Encephalopathies: a systematic review protocol

BackgroundDevelopmental and Epileptic Encephalopathies (DEEs) are defined by drug-resistant seizures and neurodevelopmental disorders. Over 50% of patients have a genetic cause. Studies have shown that patients with DEEs, regardless of genetic diagnosis, experience a central visual function disorder known as Cerebral (cortical) Visual Impairment (CVI). The prevalence of CVI in DEE patients is currently unknown. A quantitative synthesis of existing data on the prevalence rates of this condition would aid in understanding the magnitude of the problem, outlining future research, and suggesting the need for therapeutic strategies for early identification and prevention of the disorder.MethodsThe protocol followed the PRISMA-P statement for systematic review and meta-analysis protocols. The review will adhere to the JBI Manual for Evidence Synthesis (Systematic Reviews of Prevalence and Incidence) and use the CoCoPop framework to establish eligibility criteria. We will conduct a comprehensive search of several databases, including MEDLINE, EMBASE, Science Direct, Scopus, PsychINFO, Wiley, Highwire Press, and Cochrane Library of Systematic Reviews. Our primary focus will be determining the prevalence of cerebral visual impairments (Condition) in patients with developmental and epileptic encephalopathy (Population). To ensure clarity, we will provide a narrative summary of the risk of bias in the studies we include. The Cochrane Q statistic will be used to assess heterogeneity between studies. If the quantitative synthesis includes more than 10 studies, potential sources of heterogeneity will be investigated through subgroup and meta-regression analyses. Meta(bias)es analysis will also be performed. The quality of evidence for all outcomes will be evaluated using the Grading of Recommendations Assessment Development and Evaluation (GRADE) working group methodology.DiscussionThis protocol outlines a systematic review and meta-analysis to identify, collect, evaluate, and integrate epidemiological knowledge related to the prevalence of CVI in patients with DEEs. To the best of our knowledge, no other systematic review and meta-analysis has addressed this specific issue. The results will provide useful information for understanding the extent of the problem, outlining future research, and suggesting the need for early identification strategies.Systematic review registrationsThis Systematic Review Protocol was registered in PROSPERO (CRD42023448910).

Multistakeholder Perspectives on the Determinants of Family Fundamental Movement Skills Practice: A Qualitative Systematic Review.

Childhood obesity is a significant public health crisis that is exposing children to associated morbidities and premature mortality. However, parents can positively influence physical activity trajectories and improve health outcomes by nurturing fundamental movement skills (FMS) in children. This is the first study to explore the determinants of family FMS practice via a systematic synthesis of qualitative evidence. Keyword searches were completed in SPORTDiscus, PubMed, Scopus, Web of Science, and Embase. Studies that offered perspectives relating to influences on the FMS of 2-6-year-old children in the family context via qualitative approaches, including visual methodologies that provided an important voice to children, were included. A thematic analysis was used to establish key themes. The emergent themes included parent knowledge and beliefs, self-efficacy of parents to teach, and the home environment. Parents often undervalued FMS and lacked the self-efficacy to teach due to poor understanding, conflicting priorities, and multifaceted societal influences. Children preferred autonomous play and socialisation but were negatively influenced by technology and restrictive household rules. Greater knowledge exchange between stakeholders is necessary to empower parents and enhance FMS application at home. More community initiatives could facilitate greater access to outdoor spaces, facilities, and equipment, which may improve family engagement with FMS.

Stakeholder-informed positivity thresholds for disease markers and risk scores: a methodological framework and an application in obstructive lung disease

ObjectivesA positivity threshold is often applied to markers or predicted risks to guide disease management. These thresholds are often decided exclusively by clinical experts despite being sensitive to the preferences of patients and general public as ultimate stakeholders. Study Design and SettingWe propose an analytical framework for quantifying the net benefit (NB) of an evidence-based positivity threshold based on combining preference-sensitive (eg, how individuals weight benefits and harms of treatment) and preference-agnostic (eg, the magnitude of benefit and the risk of harm) parameters. We propose parsimonious choice experiments to elicit preference-sensitive parameters from stakeholders, and targeted evidence synthesis to quantify the value of preference-agnostic parameters. We apply this framework to maintenance of azithromycin therapy for chronic obstructive pulmonary disease using a discrete choice experiment to estimate preference weights for attribute level associated with treatment. We identify the positivity threshold on 12-month moderate or severe exacerbation risk that would maximize the NB of treatment in terms of severe exacerbations avoided. ResultsIn the case study, the prevention of moderate and severe exacerbations (benefits) and the risk of hearing loss and gastrointestinal symptoms (harms) emerged as important attributes. Four hundred seventy seven respondents completed the discrete choice experiment survey. Relative to each percent risk of severe exacerbation, preference weights for each percent risk of moderate exacerbation, hearing loss, and gastrointestinal symptoms were 0.395 (95% confidence interval [CI] 0.338–0.456), 1.180 (95% CI 1.071–1.201), and 0.253 (95% CI 0.207–0.299), respectively. The optimal threshold that maximized NB was to treat patients with a 12-month risk of moderate or severe exacerbations ≥12%. ConclusionThe proposed methodology can be applied to many contexts where the objective is to devise positivity thresholds that need to incorporate stakeholder preferences. Applying this framework to chronic obstructive pulmonary disease pharmacotherapy resulted in a stakeholder-informed treatment threshold that was substantially lower than the implicit thresholds in contemporary guidelines. Plain Language SummaryDoctors often compare disease markers (such as laboratory results) or risk scores for a patient with cut-off values from guidelines to decide which patients need to be treated. For example, guidelines recommend that patients whose 10-year risk of heart attack is more than 10% be given statin pills. However, guidelines that recommend such treatment rules might not consider what matters most to patients (like how much they do not like side effects of the drugs). In this study, we propose a mathematical method where preferences of individuals on the trade-off between treatment benefits and harms can be used to determine the best treatment rule. We apply this method to the choice of antibiotic therapy for patients with lung airway diseases. We find that, given patient and public preferences on treatment benefit and risks, those with a 12% or more risk of experiencing a lung attack should receive antibiotic therapy. This patient-oriented cut-off is significantly lower than the cut-off values currently used by guidelines, which are in the 60%–70% range. We recommend applying this method whenever scientists must make recommendations on treatment rules where patient or public preferences might influence those rules.

Exploring patient perception of decision-making in carpal tunnel release surgery: A systematic review and thematic synthesis of qualitative studies.

Carpal tunnel syndrome is a common condition, but some controversies remain regarding diagnostics and the most effective treatments. As a result, patients often experience decisional conflicts, especially when considering carpal tunnel release surgery. Understanding factors that influence decision-making in surgery can help clinicians better grasp patient treatment preferences and priorities, reducing decisional conflicts, and enabling patients to make informed, value-aligned choices through shared decision-making. This qualitative evidence synthesis aims to explore patient perceptions of carpal tunnel release, examine the decision-making factors, and critically appraise and synthesise the existing evidence. A systematic search was conducted across four electronic databases (MEDLINE, EMBASE, CINAHL Ultimate, PsycINFO) from inception to August 2023, supplemented by referencing and citation searching to identify eligible qualitative studies. Thematic synthesis was adopted as synthesis methodology, involving a line-by-line coding of the primary study findings, and the development of descriptive and analytical themes. Quality appraisal was conducted using the modified Critical Appraisal Skills Programme checklist, supplemented with the COnsolidated criteria for REporting Qualitative research checklist. Synthesis of six qualitative studies encompassing 66 participants generated five analytical themes: (1) Journey to normalcy, (2) Patient-centred care, (3) Work and life considerations, (4) Weighing up alternatives, and (5) Shaping the expectations, highlighting the complexity of patient decision-making in carpal tunnel release. In the management of carpal tunnel syndrome, therapists should consider various decision-making factors, prioritising communication and shared decision-making. This, along with personalised interactions, achieves patient-centred care and enhances patient care quality and therapeutic alliance.

MPES-R: Multi-Parameter Evidence Synthesis in R for Survival Extrapolation-A Tutorial.

Survival extrapolation often plays an important role in health technology assessment (HTA), and there are a range of different approaches available. Approaches that can leverage external evidence (i.e. data or information collected outside the main data source of interest) may be helpful, given the extent of uncertainty often present when determining a suitable survival extrapolation. One of these methods is the multi-parameter evidence synthesis (MPES) approach, first proposed for use in HTA by Guyot et al., and more recently by Jackson. While MPES has potential benefits over conventional extrapolation approaches (such as simple or flexible parametric models), it is more computationally complex and requires use of specialist software. This tutorial presents an introduction to MPES for HTA, alongside a user-friendly, publicly available operationalisation of Guyot's original MPES that can be executed using the statistical software package R. Through two case studies, both Guyot's and Jackson's MPES approaches are explored, along with sensitivity analyses relevant to HTA. Finally, the discussion section of the tutorial details important considerations for analysts considering use of an MPES approach, along with potential further developments. MPES has not been used often in HTA, and so there are limited examples of how it has been used and perceived. However, this tutorial may aid future research efforts exploring the use of MPES further.

Understanding lived experiences and perceptions of perinatal depression in Nigeria: a qualitative evidence synthesis

Background Perinatal depression is a common mental health disorder which spans during and after pregnancy. Unfortunately, there is poor healthcare-seeking behaviour for this treatable condition. Additionally, maternal healthcare workers sometimes overlook the signs and symptoms, failing to diagnose it adequately. This review aims to provide a framework for understanding the in-depth perceptions and implementation gaps surrounding perinatal depression in Nigeria. Methods This study employed a rigorous qualitative evidence synthesis methodology to gather and analyse both published and unpublished qualitative research on the lived experiences and perceptions of perinatal depression in Nigeria. The research was conducted by searching multiple electronic databases, citation chaining, and checking reference lists. The studies were then screened by title, abstract, and full text, and the quality of the included studies was evaluated using the Critical Appraisal Skills Programme (CASP) checklist for appraising a qualitative study. The data extracted from these studies were then synthesized using the ‘best-fit’ framework method, which combines deductive and inductive approaches to analysis. Results 10 eligible papers were identified. Data were organised into themes eight themes mapped to an already existing framework: Recognitions of perinatal mental distress, labelling of mental distress, symptom patterns, social norms, roles and expectations, supernatural factors, physical/bodily issues, coping strategies, help-seeking from professionals/medical institutions. No study was excluded as a result of methodological limitations. Conclusions The review highlights the significance of integrating mental health services into routine perinatal care and the need for comprehensive interventions that consider sociocultural factors. The findings emphasize the importance of increasing awareness and education among women and healthcare providers to improve early detection and intervention. Healthcare professionals play a crucial role in identifying and managing perinatal depression; therefore, it is essential to provide them with comprehensive and regular training.

Evidence-based research of the indicator system for evaluating the application effect of TCM standards

The traditional Chinese medicine evaluation indicator system can effectively identify and recognize deficiencies in the implementation of standards and provide a rationale for improving the technical content, enhancing the effectiveness of implementation and promoting the dissemination of traditional Chinese medicine culture and technology globally. Evidence-based principles can be an important method to guide the development of traditional Chinese medicine indicators and to promote the application of standards. This paper introduces the development status of NICE indicators and provides reference ideas for constructing evaluation indicator for traditional Chinese medicine standards application based on evidence-based principles. The specific steps for constructing an evaluation indicator system for traditional Chinese medicine standard application include identifying indicator domains, evidence synthesis, developing indicators, constructing an indicator system, cost- effectiveness and resource impact analyses, and finalizing indicators for training and promotion. In order to promote the further development of traditional Chinese medicine, it is necessary to strengthen the integrated construction of “guidelines-standards-indicators”, accelerate the establishment of a coordination mechanism between domestic and international organizations, and pay attention to the characteristics of traditional Chinese medicine and focusing on implications for practice and policy.

Non-operating Room Anesthesia (NORA): A Comprehensive Review of Monitored Anesthesia Care.

Monitored anesthesia care (MAC) is being increasingly employed in non-operative environments, particularly in the realms of endoscopy and magnetic resonance imaging (MRI) procedures. This in-depth analysis delves into the essential components of MAC within these specific contexts, with a primary focus on ensuring patient safety, evaluating efficacy, and assessing procedural outcomes. It is a common practice in endoscopic procedures to necessitate sedation for the purpose of alleviating discomfort and anxiety, ultimately ensuring patient cooperation and the successful completion of the procedure. MAC, which entails the administration of sedatives and analgesics under the close supervision of an anesthesia professional, offers a personalized approach that carefully balances the depth of sedation with maintaining optimal patient safety standards. Within the domain of MRI procedures, where challenges such as claustrophobia and motion artifacts can significantly impact the process, MAC plays a crucial role in providing a controlled setting that not only enhances image quality but also improves patient compliance throughout the procedure. The review extensively investigates the various pharmacological agents commonly utilized in these scenarios, including but not limited tomidazolamand fentanyl, shedding light on their pharmacokinetic and pharmacodynamic properties specific to these contexts. Furthermore, the critical role of the anesthesia provider in effectively managing potential complications, such as respiratory depression, hemodynamic instability, and allergic reactions, is thoroughly examined and discussed. The analysis extends to the implementation of MAC protocols, encompassing pre-procedural assessments, continuous intra-procedural monitoring, and comprehensive post-procedural care, all aimed at ensuring the best possible outcomes for patients. Additionally, the review delves into the economic considerations associated with MAC, taking into account its impact on procedural efficiency, healthcare costs, and patient throughput within these settings. By exploring current guidelines and recommendations established by professional societies such as the American Society of Anesthesiologists (ASA), this review aims to provide a holistic understanding of the best practices in MAC for both endoscopy and MRI procedures. Through the synthesis of available evidence, the primary objective of this review is to contribute to informing clinical practices, enhancing patient safety measures, improving procedural success rates, and ultimately advocating for the broader adoption of monitored anesthesia care in diverse non-operative medical settings.

Integrating deep learning architectures for enhanced biomedical relation extraction: a pipeline approach.

Biomedical relation extraction from scientific publications is a key task in biomedical natural language processing (NLP) and can facilitate the creation of large knowledge bases, enable more efficient knowledge discovery, and accelerate evidence synthesis. In this paper, building upon our previous effort in the BioCreative VIII BioRED Track, we propose an enhanced end-to-end pipeline approach for biomedical relation extraction (RE) and novelty detection (ND) that effectively leverages existing datasets and integrates state-of-the-art deep learning methods. Our pipeline consists of four tasks performed sequentially: named entity recognition (NER), entity linking (EL), RE, and ND. We trained models using the BioRED benchmark corpus that was the basis of the shared task. We explored several methods for each task and combinations thereof: for NER, we compared a BERT-based sequence labeling model that uses the BIO scheme with a span classification model. For EL, we trained a convolutional neural network model for diseases and chemicals and used an existing tool, PubTator 3.0, for mapping other entity types. For RE and ND, we adapted the BERT-based, sentence-bound PURE model to bidirectional and document-level extraction. We also performed extensive hyperparameter tuning to improve model performance. We obtained our best performance using BERT-based models for NER, RE, and ND, and the hybrid approach for EL. Our enhanced and optimized pipeline showed substantial improvement compared to our shared task submission, NER: 93.53 (+3.09), EL: 83.87 (+9.73), RE: 46.18 (+15.67), and ND: 38.86 (+14.9). While the performances of the NER and EL models are reasonably high, RE and ND tasks remain challenging at the document level. Further enhancements to the dataset could enable more accurate and useful models for practical use. We provide our models and code at https://github.com/janinaj/e2eBioMedRE/.

Understanding capabilities, opportunities and motivations to engage in physical activity for adults with intellectual disabilities: A qualitative evidence synthesis.

There is a paucity of theory-informed physical activity research with adults with intellectual disabilities. This study aimed to address this by synthesising existing literature and applying the COM-B model to understand capabilities, opportunities and motivations. A qualitative evidence synthesis was conducted and reported in accordance with PRISMA guidelines and the ENTREQ. Three databases were systematically searched up to and including February 2022. Qualitative research relating to the physical activity of adults with intellectual disabilities were included. Thematic synthesis was conducted with themes mapped onto the COM-B model. Twenty-five studies were included. Influences of physical activity were identified and mapped onto the COM-B model, which also included COM-B influences of social support provided by caregivers. There are many complex influences of physical activity for adults with intellectual disabilities. Researchers should consider the influences contributing to caregivers' capacity to support physical activity.
