RESUMO

The utilization of natural teeth as denture abutments offers a significant advantage in retarding the residual ridge resorption (RRR). This approach distributes stress concentration between the denture-bearing areas and abutment teeth, thereby mitigating issues such as loss of sensory feedback, compromised mastication, and aesthetic concerns. Overdentures, by providing additional support and stability, play a pivotal role in reducing RRR while enhancing stability and retention. A cast partial denture (CPD) becomes the first choice in cases of long edentulous span where cross-arch stabilization is required. The simplicity of insertion, removal, and maintenance, coupled with effective oral hygiene practices, make CPDs a practical solution. This case presentation illustrates the successful prosthetic rehabilitation of a partially dentate patient through the implementation of a maxillary overdenture and mandibular CPD underscoring the efficacy of this treatment modality in achieving optimal outcomes. The combination of these prostheses restored the masticatory function, improved the aesthetics, and enhanced the quality of life of the patient. This case highlights the effectiveness of dual-arch prosthetic solutions in achieving comprehensive rehabilitation in partially dentate patients.

RESUMO

Since 1991, there have been significant changes in medical education in Georgia. Key changes include adapting national legislation toward international standards, establishing the National Center for Education Quality Enhancement (NCEQE), which was recognized in 2018 by the World Federation for Medical Education (WFME) as an accrediting agency and opening the Association for Medical Education in Europe (AMEE) International Networking Center in 2019. Undergraduate medical education, regulated by the Ministry of Education, Science and Youth of Georgia, spans six years. MD graduates then have options for further career paths, including working as junior doctors, residency, and/or pursuing PhD research.The main challenges the country presently faces are:the need to reduce the increasing number of (mainly) private medical schools. Recent updates to the national standards for undergraduate medical education have imposed stricter accreditation requirements for MD programs, resulting in the closure of schools that fail to meet these standards;postgraduate medical education is governed by the Ministry of Internally Displaced Persons from the Occupied Territories, Labor, Health and Social Affairs of Georgia (MOH) and needs further reform due to limited and paid residency positions;continuous professional development (CPD) was optional until recently, which led to an increase in professional inaccuracy and malpractice cases. To address this, regulatory bodies, including the MOH and professional associations, are preparing the legal basis for introducing compulsory CPD.

RESUMO

The SARS-CoV-2 helicase, non-structural protein 13 (Nsp13), plays an essential role in viral replication, translocating in the 5' → 3' direction as it unwinds double-stranded RNA/DNA. We investigated the impact of structurally distinct DNA lesions on DNA unwinding catalyzed by Nsp13. The selected lesions include two benzo[a]pyrene (B[a]P)-derived dG adducts, the UV-induced cyclobutane pyrimidine dimer (CPD), and the pyrimidine (6-4) pyrimidone (6-4PP) photolesion. The experimentally observed unwinding rate constants (kobs) and processivities (P) were examined. Relative to undamaged DNA, the kobs values were diminished by factors of up to ~15 for B[a]P adducts but only by factors of ~2-5 for photolesions. A minor-groove-oriented B[a]P adduct showed the smallest impact on P, which decreased by ~11% compared to unmodified DNA, while an intercalated one reduced P by ~67%. However, the photolesions showed a greater impact on the processivities; notably, the CPD, with the highest kobs value, exhibited the lowest P, which was reduced by ~90%. Our findings thus show that DNA unwinding efficiencies are lesion-dependent and most strongly inhibited by the CPD, leading to the conclusion that processivity is a better measure of DNA lesions' inhibitory effects than unwinding rate constants.

RESUMO

PURPOSE: Engagement in CME/CPD has a positive impact on healthcare professionals' (HCPs) knowledge, skills, and performance, and on patient outcomes, therefore it is critical to better understand the components of CME/CPD systems that foster engagement, high-quality education, and impact. METHODS: An assessment of CME/CPD systems was conducted using a mixed-methods approach that included interviews with in-country subject matter experts and qualitative and quantitative data from practicing in-country physicians. RESULTS: Results demonstrate areas of consistency in CME/CPD systems across world regions that included: types of educational providers; types of credit; educational formats; self-tracking of participation; high-degree of compliance when education is mandatory; overall satisfaction with available education; strong support for interprofessional education; and lack of alignment or evaluation of engagement in education with population health outcomes. Areas of variation included: whether engagement in education is required as a condition to practice medicine; whether regulations are uniformly applied; if mechanisms to ensure independence existed; and physician perceptions of independence. CONCLUSION: Results of this assessment maybe used by a variety of different stakeholders to assess how well country-level CME/CPD systems are meeting the needs of practicing physicians and determine what, if any, changes might need to be implemented to improve outcomes.

RESUMO

The Saudi Commission for Health Specialties (SCFHS), the regulatory agency for health professions in the Kingdom of Saudi Arabia (KSA), sought to evolve the continuing professional development (CPD) ecosystem for the country and to promote the concept of life-long learning for healthcare professionals. SCFHS audited its own CPD accreditation system, reviewed internationally recognised CPD accreditation criteria, adopted a new set of standards, and trained its staff and provider community in their adoption. SCFHS also deployed a range of programmes and grants to support healthcare educators and researchers engaged in CPD. SCFHS recruited and trained new staff and deployed an updated IT system to support system change. The adopted criteria and standards now align with best practices, as outlined by the Accreditation Council for Continuing Medical Education (ACCME) and the International Academy for CPD Accreditation. More than 170 educators have participated in programmes to learn effective CPD pedagogy. The adoption of new standards resulted in 396 providers seeking provider accreditation. The number of CPD accredited activities produced in the KSA and approved by the SCFHS has grown from 1,000 activities in 2002 to 10,500 in 2022. With leadership support, regulatory evolution to align with best practices supports healthcare educators and effectively expands of the diversity and quality of CPD.

RESUMO

BACKGROUND: Being the professional membership body for pharmacists in Jordan, the Jordan Pharmacists Association (JPA) took the initiative to establish a training centre for practising pharmacists. This study aims to identify the self-assessed training priorities of community pharmacists in Jordan. METHODS: In the period between August and October 2022, an online self-administered questionnaire was distributed using a variety of participants' identification and recruitment approaches. The questionnaire targeted currently practising community pharmacists. Data were analysed descriptively and inferentially. RESULTS: In total, 470 community pharmacists participated in this study. Of 470 participants, 307 (65.3%) were employees, of which 206 were full-time employees. Results showed that only 97 (21%) had access to an in-house training programme or scheme. Self-assessment of training needs highlighted differences between the three competencies clusters. While administrative and managerial skills and competencies were more frequently prioritised on average than the other two clusters, interpersonal and communication skills were needed the least. Evidence showed a significant difference between female and male participants regarding the need for training addressing maternity and early childhood health training issues. Lastly, the role-based comparison showed that, compared to pharmacy owners, employees had a significantly higher need for training related to bookkeeping and taxation returns preparation and how to handle and manage records of narcotic and controlled medicines. CONCLUSIONS: If training and development programmes are tailored to address specific needs in administrative, clinical, and interpersonal competencies, community pharmacists have the potential to enhance public health, expand their role, provide patient-centred care, and support the national healthcare system.

RESUMO

Aims of this assessment were to describe requirements for physicians to engage in CME/CPD; explore perceptions of In-Country SMEs of their CME/CPD systems; describe perceptions of In-Country physicians about interprofessional continuing education (IPCE) and independent CME/CPD; and provide recommendations that may be adopted to improve quality and effectiveness. This assessment used a mixed-methods approach that included 1:1 interviews with in-country subject matter experts and an electronic survey capturing qualitative and quantitative data from practicing in-country physicians. This assessment reflects a country invested in the education of its physician workforce. CME/CPD systems have embedded governance structures, organizations authorized to provide education, and a recognized credit system. Governing bodies have implemented regulations to limit influence from commercial interest organizations on CME/CPD, and there is opportunity to expand delivery systems to reach physicians across diverse geographic regions, better align content to individual physicians' gaps and learning needs, and reduce cost. There is opportunity to invest in IPCE within a country with a strong professional hierarchy system. This assessment reflects CME/CPD systems that are relatively mature and identifies several opportunities to expand and enhance systems to better meet educational needs of physicians and to positively impact practice and patient outcomes.

RESUMO

Photoprotective properties of 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) to reduce UV-induced DNA damage have been established in several studies. UV-induced DNA damage in skin such as single or double strand breaks is known to initiate several cellular mechanisms including activation of poly(ADP-ribose) (pADPr) polymerase-1 (PARP-1). DNA damage from UV also increases extracellular signal-related kinase (ERK) phosphorylation, which further increases PARP activity. PARP-1 functions by using cellular nicotinamide adenine dinucleotide (NAD+) to synthesise pADPr moieties and attach these to target proteins involved in DNA repair. Excessive PARP-1 activation following cellular stress such as UV irradiation may result in excessive levels of cellular pADPr. This can also have deleterious effects on cellular energy levels due to depletion of NAD+ to suboptimal levels. Since our previous work indicated that 1,25(OH)2D3 reduced UV-induced DNA damage in part through increased repair via increased energy availability, the current study investigated the effect of 1,25(OH)2D3 on UV-induced PARP-1 activity using a novel whole-cell enzyme- linked immunosorbent assay (ELISA) which quantified levels of the enzymatic product of PARP-1, pADPr. This whole cell assay used around 5000 cells per replicate measurement, which represents a 200-400-fold decrease in cell requirement compared to current commercial assays that measure in vitro pADPr levels. Using our assay, we observed that UV exposure significantly increased pADPr levels in human keratinocytes, while 1,25(OH)2D3 significantly reduced levels of UV-induced pADPr in primary human keratinocytes to a similar extent as a known PARP-1 inhibitor, 3-aminobenzamide (3AB). Further, both 1,25(OH)2D3 and 3AB as well as a peptide inhibitor of ERK-phosphorylation significantly reduced DNA damage in UV-exposed keratinocytes. The current findings support the proposal that reduction in pADPr levels may be critical for the function of 1,25(OH)2D3 in skin to reduce UV-induced DNA damage.

RESUMO

OBJECTIVES: There is an increasing need to engage with evidence-based practice (EBP) and continuing professional development (CPD) to effectively respond to the current healthcare demands and challenges. This review critically synthesises key knowledge diffusion and implementation theories, with particular emphasis on Communities of Practice (CoPs), a theory as yet unexplored in radiography practice. KEY FINDINGS: Prominent theories including implementation science, translational science and knowledge diffusion theories have previously been proposed to bridge the theory-practice gap. However, the radiography profession is a fast-paced, complex and a highly regulated profession which makes the application of rigid theories more challenging. CoPs, which have their origins in Social Learning Theory, represents a potentially more viable approach to bridging the theory-practice gap. CONCLUSION: Cultivating and maintaining CoPs is a more practical approach to improve knowledge dissemination, EBP and CPD, allowing radiographers in practice to share knowledge, best practices, and experiences out with an organisational hierarchy. The collective pool of knowledge, and history created may contribute to further establishing the radiography profession and the radiographer identity as the CoPs connect, expand, and advance over time. IMPLICATIONS FOR PRACTICE: CoPs may be cultivated and further investigated in radiography practice to improve knowledge dissemination, EBP and CPD, with the ultimate aim of improving individual and organisational performance in radiography practices.

RESUMO

BACKGROUND: Healthcare professionals constitute a critical component of clinical care services. To provide the expected service, they must continuously develop their profession through continuous learning. This kind of learning is recognized as continuing professional development (CPD). Traditionally, CPD is offered onsite. Onsite training is associated with some barriers that prevent healthcare professionals from attending such educational activities, including financial difficulties and long distance. This is why online learning is proposed to overcome these barriers. OBJECTIVE: The main purpose was to evaluate usability, knowledge and challenges of e-learning platforms for CPD of healthcare professionals at University Teaching Hospital of Kigali (CHUK). METHODS: The cross-sectional quantitative study approach was utilized; the data was collected at the workplace of nurses, midwives, and allied health professionals by using a pre-designed questionnaire. The data were analyzed using Statistical Package for the Social Sciences (SPSS) version 25 and presented as frequencies. RESULTS: A significant majority was aware of CPD e-learning platforms. For example, 95.7% of the participants were familiar with these platforms, indicating that they had some degree of knowledge about their existence and purpose. Regarding the mode of accessing CPD courses, 82.1% of participants preferred online platforms, demonstrating a strong will to use e-learning platforms. CONCLUSION: This study highlighted a high level of awareness and utilization of CPD e-learning platforms among healthcare professionals at CHUK, additionally, participants expressed confidence in using the platforms but emphasized the need for further support and training.

RESUMO

There was a renewed vigour among the participants attending the 16th Annual European CME Forum (#16ECF), which took place in the Hague, the Netherlands from 8-10 November 2023. This emanated from the meeting having reverted to an in-person format to promote engagement among attendees. The meeting was subdivided into three main sections to address this year's theme "Voices in CME-CPD": 1) Listening to others; 2) Listening to ourselves; 3) Listening to each other. The Forum unofficially began with the pre-meeting sessions led by two special interest groups and was then formally opened by the programme director. There were panel discussions on designing and implementing CME-CPD programmes, measuring and reporting outcomes, and valuing and defining independence, as well as smaller workshop and breakout sessions led by international presenters. Representatives for the Journal of CME presented on the 2023 Special Collection of articles, with this year's topic "Expanding the voices in CME-CPD" mirroring the meeting theme. Participants interacted with providers, accreditors and grantors, as well as poster authors and a local physician who attended to share a learner's perspective. The meeting concluded with the now familiar "CME unsession" to ensure everyone's voices were heard and no one left the meeting with any unanswered questions.

RESUMO

Background: Continuing education (CE) is an essential requirement for pharmacy professionals to stay abreast with the evolving knowledge and skills of the practice and meet the regulatory mandate. The purpose of this research is to assess factors affecting the satisfaction of pharmacists and pharmacy technicians towards CE practices in Saudi Arabia. Material and methods: A self-administered survey instrument was developed following an extensive literature search. The questionnaire consisted of three sections: participants' demographics, data on CE activities over the past year and overall satisfaction, and statements of barriers (14 items) and facilitators (12 items) for participation in CE activities (scored on a 5-point Likert scale (5 = always, 1 = never)). The survey was piloted and then distributed as a link through the Saudi Commission for Health Specialties and Saudi Pharmaceutical Society (SPS) between Jan 2018 and Feb 2019. Results: Data was available on 398 pharmacists and 40 pharmacy technicians (completion rate was 55 %). The majority were practitioners, male, working in a hospital setting and had more than five years of practice experience. Half of the participants were from the Central Region and about one-third were non-Saudi. Only a quarter of the participants were satisfied/very satisfied with the current CE practices in Saudi Arabia. Job constraints (62.7 %), cost (55.9 %), schedule of CE activities (55.4 %), lack of information on CE opportunities (53 %) and professional burnout (49.7 %) were the top barriers. There was a significant level of dissatisfaction among pharmacy technicians when compared to pharmacists (p = 0.003), as well as among Saudi pharmacists when compared to non-Saudi pharmacists (p = 0.002). Lack of relevant CE activities (p = 0.05), lack of quality activities (p = 0.002), lack of recognition (p = 0.013) and lack of internet access (p = 0.006) were significantly more barriers for pharmacy technicians compared to pharmacists. The most identified facilitators to engage in CE activities were a personal desire to learn (78.4 %), the requirement to maintain a professional license (73.8 %) and relaxation provided by learning (58.5 %) and networking opportunities (53.4 %). The majority of the participants preferred conferences or interactive workshops, short CE over half a day or less, and the topic of disease management/drug therapy. Conclusion: The findings of the study highlight the need for a partnership strategy that includes various stakeholders to improve CE program quality and accessibility that supports and promotes the professional development of pharmacists and pharmacy technicians in Saudi Arabia. It also underscores the importance of meeting the preferences of pharmacy practitioners when designing CE programs and aligning such activities with their practices.

RESUMO

UV light is a potent mutagen that induces bulky DNA damage in the form of cyclobutane pyrimidine dimers (CPDs). Photodamage and other bulky lesions occurring in nuclear genomes can be repaired through nucleotide excision repair (NER), where incisions on both sides of a damaged site precede the removal of a single-stranded oligonucleotide containing the damage. Mitochondrial genomes (mtDNAs) are also susceptible to damage from UV light, but current evidence suggests that the only way to eliminate bulky mtDNA damage is through mtDNA degradation. Damage-containing oligonucleotides excised during NER can be captured with antidamage antibodies and sequenced (XR-seq) to produce high-resolution maps of active repair locations following UV exposure. We analyzed previously published datasets from Arabidopsis thaliana, Saccharomyces cerevisiae, and Drosophila melanogaster to identify reads originating from the mtDNA (and plastid genome in A. thaliana). In A. thaliana and S. cerevisiae, the mtDNA-mapping reads have unique length distributions compared to the nuclear-mapping reads. The dominant fragment size was 26 nt in S. cerevisiae and 28 nt in A. thaliana with distinct secondary peaks occurring in regular intervals. These reads also show a nonrandom distribution of di-pyrimidines (the substrate for CPD formation) with TT enrichment at positions 7-8 of the reads. Therefore, UV damage to mtDNA appears to result in production of DNA fragments of characteristic lengths and positions relative to the damaged location. The mechanisms producing these fragments are unclear, but we hypothesize that they result from a previously uncharacterized DNA degradation pathway or repair mechanism in mitochondria.

RESUMO

AIM: This study aims to identify the prospective skill requirements for future radiographers practising in the United Arab Emirates (UAE). Such information will inform educational institutions, healthcare organisations, and policymakers in developing effective strategies. METHODS: A cross-sectional study was conducted involving currently practising radiographers, nuclear medicine technologists, sonographers, and radiation therapists in the UAE (n =74). A comprehensive survey questionnaire was developed and validated through piloting and expert consultations. Ethical approval was obtained, and data were collected through purposive sampling. Descriptive statistics, reliability analysis, Chi-square tests, and factor analysis were employed in the data analysis. RESULTS: The results showed that 73%, 47.3%, 43.2%, 40.5%, 39.2%, 33.8% interested in radiology safety, image interpretation, interprofessional and interpersonal skills, research and managerial skills, Picture Archiving and Communication System (PACS) administration and AI (Artificial Intelligence) and, clinical supervision and assessment, respectively. The factor analysis showed four factors factor considered for CPD training are training settings (15.12), training topics (1.88), CPD credits (1.72) and, presenter and expenses (1.49). CONCLUSION: This study sheds light on the CPD requirements and aspirations of radiographers in the UAE, offering insights into their preferences and challenges. These findings can inform strategies for improving CPD opportunities and ensuring that radiographers are equipped to meet the evolving healthcare demands in the UAE, including performing enhanced practice. IMPLICATIONS FOR PRACTICE: Development of flexible and comprehensive CPD programmes tailored to radiographers' career interests is required. Employers should provide financial support and flexibility in training options. Regulatory bodies should continue to mandate CPD, fostering a culture of lifelong learning. Supportive work environments, interdisciplinary collaboration, and technological fluency are crucial. Emphasising patient-centred care, research opportunities, and continuous assessment further enhances radiography practice.

RESUMO

Acute kidney injury (AKI) is defined as sudden loss of renal function characterized by increased serum creatinine levels and reduced urinary output with a duration of 7 days. Ferroptosis, an iron-dependent regulated necrotic pathway, has been implicated in the progression of AKI, while ferrostatin-1 (Fer-1), a selective inhibitor of ferroptosis, inhibited renal damage, oxidative stress and tubular cell death in AKI mouse models. However, the clinical translation of Fer-1 is limited due to its lack of efficacy and metabolic instability. In this study we designed and synthesized four Fer-1 analogs (Cpd-A1, Cpd-B1, Cpd-B2, Cpd-B3) with superior plasma stability, and evaluated their therapeutic potential in the treatment of AKI. Compared with Fer-1, all the four analogs displayed a higher distribution in mouse renal tissue in a pharmacokinetic assay and a more effective ferroptosis inhibition in erastin-treated mouse tubular epithelial cells (mTECs) with Cpd-A1 (N-methyl-substituted-tetrazole-Fer-1 analog) being the most efficacious one. In hypoxia/reoxygenation (H/R)- or LPS-treated mTECs, treatment with Cpd-A1 (0.25 µM) effectively attenuated cell damage, reduced inflammatory responses, and inhibited ferroptosis. In ischemia/reperfusion (I/R)- or cecal ligation and puncture (CLP)-induced AKI mouse models, pre-injection of Cpd-A1 (1.25, 2.5, 5 mg·kg-1·d-1, i.p.) dose-dependently improved kidney function, mitigated renal tubular injury, and abrogated inflammation. We conclude that Cpd-A1 may serve as a promising therapeutic agent for the treatment of AKI.

RESUMO

The CPD landscape is rapidly evolving and may be affecting patient outcomes. This also poses challenges to healthcare professionals, some of whom are experiencing a lot of stress leading to burnout. Medical and residency training are very structured and the importance of CPD occurring in a non-structured setting to prevent professional stagnation cannot be overemphasized. The need for lifelong learning post- residency, which encompasses a much longer period until retirement, is underscored hence the need for a cultural shift. Adult learning needs emphasis and a focus on addressing individual needs is required. Reasons for physician reluctance and inertia towards CPD such as lack of time, self-sufficiency, occasional journal reading, and skepticism need ongoing exploration. Comprehensive measures, including integrated EMR designs, personal learning projects, practice updates, reward systems, physician surveys, equal weight for formal and informal CPD, and promoting a learning mindset are proposed.

RESUMO

BACKGROUND: In the dynamic field of pharmacy amongst a diverse array of countries with disparate income levels, pharmacists play a pivotal role in integrating emerging scientific knowledge into their practice while adapting to evolving therapeutic interventions and expanding service delivery responsibilities. Lifelong Learning (LLL) is cultivated through continuing professional education (CPE) and continuing professional development (CPD), indispensable components ensuring sustained professional competence and heightened patient care quality. The global landscape witnesses diverse LLL activities tailored to pharmacists' learning needs and preferences. This scoping review maps and synthesises a comprehensive global perspective on the existing knowledge regarding CPE/CPD models, statutory requirements, and pharmacists' preferences for LLL activities. OBJECTIVE: To comprehensively investigate global models of CPE/CPD for pharmacists' and examine the statutory requirements governing pharmacists' registration and licensure. METHOD: A literature search of PubMed, Google Scholar, Web of Science, and the University of KwaZulu-Natal library search engine was undertaken for studies between January 2012 and February 2023. The article selection and reporting followed the recommendations made by PRISMA (Preferred Reporting Items of Systematic Reviews and Meta-Analyses) guidelines. The articles were tabulated based on their respective country's income level, continuing education models employed, country-specific statutory requirements, and pharmacists' preferences for LLL activities. RESULTS: Of the initial 3974 publications identified through the database search, 24 studies met the review criteria. The majority of the articles originated from high-income countries (HICs) (14/24, 58.3%), and most employed the mandatory CPD points system (21/24, 87.5%). However, in some HICs and upper-middle income countries (UMICs), the CPE/CPD is non-mandatory. While most countries (19/24, 79.2%) offer various LLL formats, the preference of pharmacists remains primarily face-to-face learning (13/24, 54.2%). However, workplace learning (3/24, 12.5%) and blended learning (7/24, 29.1%) are mentioned in some studies. CONCLUSION: Diverse models of CPE/CPD alongside statutory requirements persist globally and evolve, shaped by varied implementation experiences. HICs lead in CPD models, while the implementation in low- and middle-income countries (LMICs) and low-income countries (LICs) requires further exploration for inclusivity and effectiveness. A few UMICs are either initiating or in early stages of implementing the CPD models. Structured planning for LLL activities is increasingly a global requirement for pharmacists' licensure. The essential progression of pharmacy practice in developing healthcare systems necessitates a mandatory CPD model. Ongoing research is crucial to fortify the implementation, align and unify the CPD model with evolving pharmacy profession needs.

RESUMO

BACKGROUND: Nurses and midwives are at the forefront of the provision of Emergency Obstetric and Neonatal Care (EmONC) and Continuous Professional Development (CPD) is crucial to provide them with competencies they need to provide quality services. This research aimed to assess uptake and accessibility of midwives and nurses to CPD and determine their knowledge and skills gaps in key competencies of EmONC to inform the CPD programming. METHODS: The study applied a quantitative, cross-sectional, and descriptive research methodology. Using a random selection, forty (40) health facilities (HFs) were selected out of 445 HFs that performed at least 20 deliveries per month from July 1st, 2020 to June 30th, 2021 in Rwanda. Questionnaires were used to collect data on updates of CPD, knowledge on EmONC and delivery methods to accessCPD. Data was analyzed using IBM SPSS statistics 27 software. RESULTS: Nurses and midwives are required by the Rwandan midwifery regulatory body to complete at least 60 CPD credits before license renewal. However, the study findings revealed that most health care providers (HCPs) have not been trained on EmONC after graduation from their formal education. Results indicated that HCPs who had acquired less than 60 CPD credits related to EmONC training were 79.9% overall, 56.3% in hospitals, 82.2% at health centres and 100% at the health post levels. This resulted in skills and knowledge gaps in management of Pre/Eclampsia, Postpartum Hemorrhage and essential newborn care. The most common method to access CPD credits included workshops (43.6%) and online training (34.5%). Majority of HCPs noted that it was difficult to achieve the required CPD credits (57.0%). CONCLUSION: The findings from this study revealed a low uptake of critical EmONC training by nurses and midwives in the form of CPD. The study suggests a need to integrate EmONC into the health workforce capacity building plan at all levels and to make such training systematic and available in multiple and easily accessible formats. IMPLICATION ON NURSING AND MIDWIFERY POLICY: Findings will inform the revision of policies and strategies to improve CPD towards accelerating capacity for the reduction of preventable maternal and perinatal deaths as well as reducing maternal disabilities in Rwanda.

RESUMO

OBJECTIVES: To evaluate the impact a novel education programme - to improve research engagement, awareness, understanding and confidence - had on a diverse health and social care workforce. Barriers and facilitators to engagement were explored together with research capacity-building opportunities and ways to embed a research culture. The programme is entitled 'Supporting The Advancement of Research Skills' (STARS programme); the paper reports findings from a health and social care setting in England, UK. METHODS: A four-level outcome framework guided the approach to evaluation and was further informed by key principles of research capacity development and relevant theory. Quantitative data were collected from learners before and after engagement; these were analysed descriptively. Semi-structured online interviews were conducted with learners and analysed thematically. A purposive sample was achieved to include a diversity in age, gender, health and social care profession, and level of attendance (regular attendees, moderate attendees and non-attenders). RESULTS: The evaluation spanned 18 half-day workshops and 11 seminars delivered by expert educators. 165 (2% of total staff at Midlands Partnership University NHS Foundation Trust (MPFT)) staffs booked one or more education sessions; 128 (77%) including Allied Health Professionals (AHPs), psychologists, nursing and midwifery, and social workers attended one or more session. Key themes of engagement with teaching sessions, relevance and impact of training and promoting a research active environment were identified with relevant sub-themes. Positive impacts of training were described in terms of research confidence, intentions, career planning and application of research skills as a direct result of training. Lack of dedicated time for research engagement, work pressures and time commitments required for the programme were key barriers. Facilitators that facilitated engagement are also described. CONCLUSIONS: Findings demonstrate the impact that a free, virtual and high-quality research education programme had at individual and organisational levels. The programme is the product of a successful collaboration between health and social care and academic organisations; this provides a useful framework for others to adapt and adopt. Key barriers to attendance and engagement spoke to system-wide challenges that an education programme could not address in the short-term. Potential solutions are discussed in relation to protecting staff time, achieving management buy-in, recognising research champions, and having a clear communication strategy.

RESUMO

Objective.Dynamic functional network connectivity (dFNC), based on data-driven group independent component (IC) analysis, is an important avenue for investigating underlying patterns of certain brain diseases such as schizophrenia. Canonical polyadic decomposition (CPD) of a higher-way dynamic functional connectivity tensor, can offer an innovative spatiotemporal framework to accurately characterize potential dynamic spatial and temporal fluctuations. Since multi-subject dFNC data from sliding-window analysis are also naturally a higher-order tensor, we propose an innovative sparse and low-rank CPD (SLRCPD) for the three-way dFNC tensor to excavate significant dynamic spatiotemporal aberrant changes in schizophrenia.Approach.The proposed SLRCPD approach imposes two constraints. First, the L1regularization on spatial modules is applied to extract sparse but significant dynamic connectivity and avoid overfitting the model. Second, low-rank constraint is added on time-varying weights to enhance the temporal state clustering quality. Shared dynamic spatial modules, group-specific dynamic spatial modules and time-varying weights can be extracted by SLRCPD. The strength of connections within- and between-IC networks and connection contribution are proposed to inspect the spatial modules. K-means clustering and classification are further conducted to explore temporal group difference.Main results.82 subject resting-state functional magnetic resonance imaging (fMRI) dataset and opening Center for Biomedical Research Excellence (COBRE) schizophrenia dataset both containing schizophrenia patients (SZs) and healthy controls (HCs) were utilized in our work. Three typical dFNC patterns between different brain functional regions were obtained. Compared to the spatial modules of HCs, the aberrant connections among auditory network, somatomotor, visual, cognitive control and cerebellar networks in 82 subject dataset and COBRE dataset were detected. Four temporal states reveal significant differences between SZs and HCs for these two datasets. Additionally, the accuracy values for SZs and HCs classification based on time-varying weights are larger than 0.96.Significance.This study significantly excavates spatio-temporal patterns for schizophrenia disease.
