RESUMEN
Rho GTPases are a family of small G proteins that regulate a wide array of cellular processes related to their key roles controlling the cytoskeleton. Cancer is a multistep disease caused by the accumulation of genetic mutations and epigenetic alterations, from the initial stages of cancer development when cells in normal tissues undergo transformation, to the acquisition of invasive and metastatic traits, responsible for a large number of cancer related deaths. In this review, we discuss the role of Rho GTPase signaling in cancer in every step of disease progression. Rho GTPases contribute to tumor initiation and progression, by regulating proliferation and apoptosis, but also metabolism, senescence, and cancer cell stemness. Rho GTPases play a major role in cell migration and in the metastatic process. They are also involved in interactions with the tumor microenvironment and regulate inflammation, contributing to cancer progression. After years of intensive research, we highlight the importance of relevant models in the Rho GTPase field, and we reflect on the therapeutic opportunities arising for cancer patients.

Polygenic risk scores (PRSs) have emerged as promising tools for the prediction of human diseases and complex traits in disease genome-wide association studies (GWAS). Applying PRSs to pharmacogenomics (PGx) studies has begun to show great potential for improving patient stratification and drug response prediction. However, there are unique challenges that arise when applying PRSs to PGx GWAS beyond those typically encountered in disease GWAS (e.g. Eurocentric or trans-ethnic bias). These challenges include: (i) the lack of knowledge about whether PGx or disease GWAS/variants should be used in the base cohort (BC); (ii) the small sample sizes in PGx GWAS with corresponding low power and (iii) the more complex PRS statistical modeling required for handling both prognostic and predictive effects simultaneously. To gain insights in this landscape about the general trends, challenges and possible solutions, we first conduct a systematic review of both PRS applications and PRS method development in PGx GWAS. To further address the challenges, we propose (i) a novel PRS application strategy by leveraging both PGx and disease GWAS summary statistics in the BC for PRS construction and (ii) a new Bayesian method (PRS-PGx-Bayesx) to reduce Eurocentric or cross-population PRS prediction bias. Extensive simulations are conducted to demonstrate their advantages over existing PRS methods applied in PGx GWAS. Our systematic review and methodology research work not only highlights current gaps and key considerations while applying PRS methods to PGx GWAS, but also provides possible solutions for better PGx PRS applications and future research.

ChatGPT has drawn considerable attention from both the general public and domain experts with its remarkable text generation capabilities. This has subsequently led to the emergence of diverse applications in the field of biomedicine and health. In this work, we examine the diverse applications of large language models (LLMs), such as ChatGPT, in biomedicine and health. Specifically, we explore the areas of biomedical information retrieval, question answering, medical text summarization, information extraction and medical education and investigate whether LLMs possess the transformative power to revolutionize these tasks or whether the distinct complexities of biomedical domain presents unique challenges. Following an extensive literature survey, we find that significant advances have been made in the field of text generation tasks, surpassing the previous state-of-the-art methods. For other applications, the advances have been modest. Overall, LLMs have not yet revolutionized biomedicine, but recent rapid progress indicates that such methods hold great potential to provide valuable means for accelerating discovery and improving health. We also find that the use of LLMs, like ChatGPT, in the fields of biomedicine and health entails various risks and challenges, including fabricated information in its generated responses, as well as legal and privacy concerns associated with sensitive patient data. We believe this survey can provide a comprehensive and timely overview to biomedical researchers and healthcare practitioners on the opportunities and challenges associated with using ChatGPT and other LLMs for transforming biomedicine and health.

BACKGROUND: Breast cancer is the most common cancer in terms of incidence and mortality among women worldwide, including in Africa, and a rapid increase in the number of new cases of breast cancer has recently been observed in sub-Saharan Africa. Oncology is a relatively new discipline in many West African countries, particularly Mali; thus, little is known about the current state of cancer care infrastructure and oncology practices in these countries. METHODS: To describe the challenges related to access to oncology care in Mali, we used a qualitative approach, following the Consolidated Criteria for Reporting Qualitative Research (COREQ). Thirty-eight semistructured interviews were conducted with health professionals treating cancer in Mali (n = 10), women with breast cancer (n = 25), and representatives of associations (n = 3), and 40 participant observations were conducted in an oncology unit in Bamako. We used the theoretical framework on access to health care developed by Levesque et al. a posteriori to organise and analyse the data collected. RESULTS: Access to oncology care is partly limited by the current state of Mali's health infrastructure (technical platform failures, repeated strikes in university hospitals, incomplete free health care and the unavailability of medicines) and exacerbated by the security crisis that has been occurring the country since 2012. The lack of specialist doctors, combined with limited screening campaigns and a centralised and fragmented technical platform in Bamako, is particularly detrimental to breast cancer treatment. Women's lack of awareness, lack of information throughout the treatment process, stereotypes and opposition to amputations all play a significant role in their ability to seek and access quality care, leading some women to therapeutically wander and others to want to leave Mali. It also leaves them in debt and jeopardises the future of their children. However, the high level of trust in doctors, the involvement of international actors, the level of social support and the growing influence of civil society on the issue of cancer also represent great current opportunities to fight cancer in Mali. CONCLUSION: Despite the efforts of successive Malian governments and the commitment of international actors, the provision of health care is still limited in the country, entrenching global inequalities in women's bodies.

BACKGROUND: Physical distancing is an effective preventative measure during respiratory infectious disease outbreaks. Prior studies on distancing behaviors have largely ignored context characteristics (physical, social) and time. PURPOSE: We investigated patterns in physical distancing over time and across situations, as well as sociodemographic variation herein. METHODS: We employed data from five rounds of a cohort study conducted throughout the pandemic by the Dutch public health institute (RIVM; N ≈ 50.000 per round). We conducted Latent Class Analyses to investigate patterns of physical distancing in a range of situations, followed by regression models to investigate associations between distancing behavior and sociodemographic and context characteristics. RESULTS: Participants differed in their general tendency to adhere to distancing guidelines across situations, but there were also substantial differences in distancing behavior between situations, particularly at work, with friends and family and outdoors. Distancing at work was strongly associated with work environment characteristics. Younger age groups reported less distancing behavior, particularly with close relations (friends or family) and at work. In periods when the pandemic situation was most severe, people adhered more strongly to distancing guidelines and age differences were most pronounced during these periods. CONCLUSIONS: Physical and social context matters for physical distancing, highlighting the importance of developing strategies for pandemic preparedness that improve opportunities for physical distancing (e.g., reducing crowding, one-way traffic) and accommodate young people to safely meet even in times of high pandemic severity and lockdowns. Future studies should account for the physical and social context in which distancing behavior is observed.
Physical distancing helps reduce the transmission of infectious diseases, but people's opportunities and willingness to keep distance from others can vary between situations. In a survey conducted at various time points during the Covid-19 pandemic, The Dutch National Public Health Institute asked people about their distancing behavior in various such situations, such as at work, when grocery shopping or when visiting with friends and family. We found that people mainly differed in their general tendency to keep distance from others: some individuals were more likely to keep distance than others in all situations. However, there were also substantial differences in distancing behavior at work, with friends and family and outdoors. Differences in distancing at work resulted from the specific work context and activities people had to perform. Younger age groups reported less distancing behavior in social situations such as when meeting with friends and family or with colleagues. In periods when the pandemic situation was most severe, people were more likely to keep their distance from others and there were larger age differences in distancing behavior. These results highlight the importance of improving people's opportunities to keep their distance from others and safely meet in times of a severe pandemic.

AIM: To study the preventable trauma deaths of hospitalized patients in the United Arab Emirates and to identify opportunities for improvement. METHODS: We analyzed the Abu Dhabi Emirate Trauma Registry data of admitted patients who died in the emergency department or in hospital from 2014 to 2019. A panel of experts categorize the deaths into not preventable (NP), potentially preventable (PP), and definitely preventable (DP). RESULTS: A total of 405 deaths were included, and 82.7% were males. The majority (89.1%) were NP, occurring mainly in the emergency department (40.4%) and the intensive care unit (49.9%). The combined potentially preventable and preventable death rate was 10.9%. The median (Interquartile range) age of the DP was 57.5 (37-76) years, compared with 32 (24-42) and 34 (25-55) years for NP and PP, respectively (p = 0.008). Most of the PP deaths occurred in the intensive care unit (55.6%), while the DP occurred mainly in the ward (50%). Falls accounted for 25% of PP and DP. Deficiencies in airway care, hemorrhage control, and fluid management were identified in 25%, 43.2% and 29.5% of the DP/PP deaths, respectively. Seventy-two percent of the Airway deficiencies occurred in the prehospital, while 34.1% of hemorrhage control deficiencies were in the emergency department. Fluid management deficiencies occurred in the emergency department and the operation theater. CONCLUSIONS: DP and PP deaths comprised 10.9% of the deaths. Most of the DP occurred in the emergency department and ward. Prehospital Airway and in-hospital hemorrhage and excessive fluid were the main areas for opportunities for improvement.

Objective: In order to be allowed to use the title "Dr. med." in Germany, an independent scientific achievement under the supervision of an established scientist is necessary. The research question, analysis and results are essentially carried out and developed independently by the doctoral student. The doctorate serves as proof that the doctoral candidate is capable of independent academic work. The acquisition of scientific skills and knowledge is of particular importance in medicine, as Germany´s international competitiveness is based on the education of today´s young academics. Fair conditions and uniform quality standards for doctoral studies are therefore indispensable to attract future young scientists at an early stage. Methods: The currently valid doctoral regulations of the medical faculties in Germany were analysed with regards to the following target criteria; update date, dissertation language, possibility of publication-based dissertation and its details (number of first and total authorships, publication organ), knowledge of methods and consideration of "Good Medical Practice" (GMP), plagiarism check, review process and disputation. Results: All faculties with the right to award doctorates, and, thus 40 valid regulations were included in the analysis. This revealed a great divergence in the requirements for doctoral candidates. Although a publication-based doctorate is now possible at 93% (n=37) of the faculties, in addition to the monographic dissertation, the required first and total authorships vary from one required first authorship (n=26, 70%) to two or three first authorships (n=5, 14%), as well as some faculties having no information regarding the number of publications (n=6, 16%). The quality of the publication organ was not described in detail in seven faculties (19%). To ensure quality, requirements have increasingly been anchored in the regulations, so that 22 regulations (56%) now stipulate participation in courses on GMP or qualification programmes. The regulations leave a lot of room for manoeuvre in terms of content and do not allow for comparability of the conditions for preparing doctoral researchers. The specifications range from mere mention, to instruction, to compulsory course participation. Another means of quality assurance is the prevention of plagiarism through the applications of software systems. However, this simple and effective means is not yet mentioned in 65% of the regulations (n=26). While the other regulations make use of this possibility, it is not an obligatory application. A total of 34 regulations provide for the regular drawing up of a supervision agreement to define the rights and obligations of the actors involved. Conclusion: The analysis showed a divergent picture. Although imprecise regulations or gaps in information allow scope for design, they also prevent transparency. Despite revisions of many regulations in the past, these revisions have not led to any significant harmonisation. The implementation of standardised and structured doctoral programmes is desirable and could be tackled within the framework of the planned amendment of medical studies. This opens up the possibility of dealing efficiently with the scarce resource of time in the face of competing curriculum content and of making a doctoral project more attractive to potential young scientists at an early stage.

INTRODUCTION: Adolescents and young women in low-middle-income countries face obstacles to accessing HIV, Sexual and Reproductive Health (SRH), and related Gender-Based Violence (GBV) services. This paper presents facilitators, opportunities, and barriers to enhance uptake of HIV, GBV, and SRH services among Adolescent Girls and Young Women (AGYW) in selected districts in Zambia. METHODS: This study was conducted in Chongwe, Mazabuka, and Mongu Districts among adolescent girls and young women in Zambia. Key informants (n = 29) and in and out-of-school adolescents and young people (n = 25) were interviewed. Purposive sampling was used to select and recruit the study participants. Interviews were transcribed verbatim, and a content analysis approach was used for analysis. RESULTS: The facilitators that were used to enhance the uptake of services included having access to health education information on comprehensive adolescent HIV and gender-based violence services. Non-governmental organisations (NGOs) were the main source of this information. The opportunities bordered on the availability of integrated approaches to service delivery and strengthened community and health center linkages with referrals for specialised services. However, the researchers noted some barriers at individual, community, and health system levels. Refusal or delay to seek the services, fear of side effects associated with contraceptives, and long distance to the health facility affected the uptake of services. Social stigma and cultural beliefs also influenced the understanding and use of the available services in the community. Health systems barriers were; inadequate infrastructure, low staffing levels, limited capacity of staff to provide all the services, age and gender of providers, and lack of commodities and specialised services. CONCLUSION: The researchers acknowledge facilitators and opportunities that enhance the uptake of HIV, GBV, and SRH services. However, failure to address barriers at the individual and health systems level always negatively impacts the uptake of known and effective interventions. They propose that programme managers exploit the identified opportunities to enhance uptake of these services for the young population.

BACKGROUND: People with long-term chronic conditions often struggle to access and navigate complex health and social services. Social prescription (SP) interventions, a patient-centred approach, help individuals identify their holistic needs and increase access to non-clinical resources, thus leading to improved health and well-being. This review explores existing SP interventions for people with long-term chronic conditions and identifies the opportunities and challenges of implementing them in primary healthcare settings. METHODS: This rapid review followed the Preferred Reporting Items for Systematic Review and Meta-analysis guidelines and searched relevant articles in three databases (PubMed/MEDLINE, EMBASE, and Web of Science) by using subject headings and keywords combined with Boolean operators. The search encompassed articles published between January 2010 and June 2023. Two authors independently conducted study screening and data abstraction using predefined criteria. A descriptive synthesis process using content analysis was performed to summarise the literature. RESULTS: Fifteen studies were included, with all but one conducted in the United Kingdom, and revealed that social prescribers help guide patients with long-term chronic conditions to various local initiatives related to health and social needs. Effective implementation of SP interventions relies on building strong relationships between social prescribers and patients, characterised by trust, empathy, and effective communication. A holistic approach to addressing the unmet needs of people with long-term chronic conditions, digital technology utilisation, competent social prescribers, collaborative healthcare partnerships, clinical leadership, and access to local resources are all vital components of successful SP intervention. However, the implementation of SP interventions faces numerous challenges, including accessibility and utilisation barriers, communication gaps, staffing issues, an unsupportive work environment, inadequate training, lack of awareness, time management struggles, coordination and collaboration difficulties, and resource constraints. CONCLUSION: The present review emphasises the importance of addressing the holistic needs of people with long-term chronic conditions through collaboration and coordination, training of social prescribers, community connections, availability of local resources, and primary care leadership to ensure successful interventions, ultimately leading to improved patient health and well-being outcomes. This study calls for the need to develop or utilise appropriate tools that can capture people's holistic needs, as well as an implementation framework to guide future contextual SP interventions.

PURPOSE: We sought to collate and summarize existing literature on donor audits (DA) and how they have been used to guide deceased organ donation and transplantation system performance and quality assurance. SOURCE: We searched MEDLINE, Cumulative Index of Nursing and Allied Health Literature, and Web of Science supplemented by Google to identify grey literature on 6 May 2022, to locate studies in English, French, and Spanish. The data were screened, extracted, and analyzed independently by two reviewers. We grouped the results into five categories: 1) motivation for DA, 2) DA methodology, 3) potential and actual donors, 4) missed donation opportunities, and 5) quality improvement. PRINCIPAL FINDINGS: The search yielded 2,416 unique publications and 52 were included in this review. Most studies were from the UK (n = 13) and published between 2001 and 2006 (n = 15). The methodologies described for DA were diverse. Our findings showed that the primary motivation for conducting DA was to identify potential donors and the number of potential deceased organ donors is significantly higher than the number of actual donors. Among retrieved studies, the proportion of donation opportunities following neurologic determination of death was 95/222 (43%) compared with 25/181 (14%) for donation after cardiocirculatory death (DCD), suggesting that the missed donation rate is higher for DCD. CONCLUSION: Donor audits help identify missed donation opportunities along the deceased donation pathway and can help support the evaluation of quality improvement initiatives.
RéSUMé: OBJECTIF: Nous avons cherché à colliger et résumer la documentation existante sur les vérifications des donneuses et donneurs (VD) et la façon dont elles ont été utilisées pour guider la performance et l'assurance de la qualité des systèmes de don et de transplantation d'organes de personnes décédées. SOURCES: Le 6 mai 2022, nous avons effectué des recherches dans MEDLINE, CINAHL et Web of Science, complétées par des recherches sur Google afin d'identifier la littérature grise et de localiser les études en anglais, en français et en espagnol. Les données ont été examinées, extraites et analysées de manière indépendants par deux personnes. Nous avons regroupé les résultats en cinq catégories : 1) motivation pour la VD, 2) méthodologie de la VD, 3) donneurs et donneuses potentiel·les et réel·les, 4) occasions de dons manquées, et 5) amélioration de la qualité. CONSTATATIONS PRINCIPALES: Notre recherche nous a permis de découvrir 2416 publications uniques et 52 ont été incluses dans cette revue. La plupart des études provenaient du Royaume-Uni (n = 13) et avaient été publiées entre 2001 et 2006 (n = 15). Les méthodologies décrites pour la vérification des donneuses et donneurs étaient diverses. Nos résultats ont montré que la principale motivation pour mener une VD était d'identifier des donneurs et donneuses potentiel·les et que le nombre potentiel de donneuses et donneurs d'organes après le décès était significativement plus élevé que le nombre réel. Parmi les études retenues, la proportion d'occasions de dons après un diagnostic de décès neurologique était de 95/222 (43 %), comparativement à 25/181 (14 %) pour le don après un décès cardiocirculatoire (DDC), ce qui suggère que le taux de dons manqués est plus élevé pour le DDC. CONCLUSION: Les vérifications des donneuses et donneurs aident à identifier les occasions de dons manquées le long du parcours de don après un décès et peuvent aider à soutenir l'évaluation des initiatives d'amélioration de la qualité.

Near the 100th anniversary of the discovery of ferroelectricity, so-called sliding ferroelectricity has been proposed and confirmed recently in a series of experiments that have stimulated remarkable interest. Such ferroelectricity exists widely and exists only in two-dimensional (2D) van der Waals stacked layers, where the vertical electric polarization is switched by in-plane interlayer sliding. Reciprocally, interlayer sliding and the "ripplocation" domain wall can be driven by an external vertical electric field. The unique combination of intralayer stiffness and interlayer slipperiness of 2D van der Waals layers greatly facilitates such switching while still maintaining environmental and mechanical robustness at ambient conditions. In this perspective, we discuss the progress and future opportunities in this behavior. The origin of such ferroelectricity as well as a general rule for judging its existence are summarized, where the vertical stacking sequence is crucial for its formation. This discovery broadens 2D ferroelectrics from very few material candidates to most of the known 2D materials. Their low switching barriers enable high-speed data writing with low energy cost. Related physics like Moiré ferroelectricity, the ferroelectric nonlinear anomalous Hall effect, and multiferroic coupling are discussed. For 2D valleytronics, nontrivial band topology and superconductivity, their possible couplings with sliding ferroelectricity via certain stacking or Moiré ferroelectricity also deserve interest. We provide critical reviews on the current challenges in this emerging area.
RESUMEN
BACKGROUND: Little data exists on the association of missed care opportunities (MCOs) in children referred for nuclear medicine/nuclear oncology imaging examinations and socioeconomic disparities. OBJECTIVE: To determine the prevalence of MCOs in children with lymphoma/leukemia scheduled for fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) and the impact of sociodemographic factors and Child Opportunity Index (COI). MATERIALS AND METHODS: Retrospective analysis of MCOs in children with lymphoma/leukemia scheduled for FDG-PET/CT (2012 to 2022) was performed. In univariate analysis, patient, neighborhood, and appointment data were assessed across MCOs and completed appointments. Logistic regression evaluated independent effects of patient-, neighborhood-, and appointment-level factors with MCOs. Two-sided P-value < .05 was considered statistically significant. RESULTS: In 643 FDG-PET/CT appointments (n = 293 patients; median age 15 years (IQR 11.0-17.0 years); 37.9% female), there were 20 MCOs (3.1%) involving 16 patients. Only 8.2% appointments involved Black/African American non-Hispanic/Latino patients, yet they made up a quarter of total MCOs. Patients living in neighborhoods with very low or low COI experienced significantly higher MCOs versus zip codes with very high COI (6.9% vs. 0.8%; P = 0.02). Logistic regression revealed significantly increased likelihood of MCOs for patients aged 18 to 21 [odds ratio (OR) 4.50; 95% CI 1.53-13.27; P = 0.007], Black/African American non-Hispanic/Latino (OR 3.20; 95% CI 1.08-9.49; P = 0.04), zip codes with very low or low COI (OR 9.60; 95% CI 1.24-74.30; P = 0.03), and unknown insurance status. CONCLUSION: Children with lymphoma/leukemia, living in zip codes with very low or low COI, and who identified as Black/African American non-Hispanic/Latino experienced more MCOs. Our study supports the need to address intersecting sociodemographic, neighborhood, and health system factors that will improve equitable access to necessary healthcare imaging for children.

BACKGROUND: Cervical cancer is a public health concern in the sub-Saharan Africa region. Cervical cancer screening is one of the strategies for detecting early precancerous lesions. However, many women have poor access to and utilization of screening services in the region. This review aimed to synthesize evidence on the challenges and opportunities of screening, early detection and management of cervical cancer in sub-Saharan Africa. METHODS: We conducted a structured narrative review of studies published in English. We included studies published from 1 January 2013 to mid-2022. Studies were selected following Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. Key search terms (detractors and enablers, cervical cancer screening, sub-Saharan Africa) were employed to identify studies from three electronic databases (HINARI, Science Direct, and PubMed). We also conducted searches on Google Scholar to identify relevant grey literatures. A thematic analysis was conducted and themes were identified, then explained using a socio-ecological framework (intrapersonal, interpersonal, organizational, community, policy levels). RESULTS: We identified 60 studies in the final review. Cervical cancer screening and early detection and management programmes are influenced by drivers at multiple levels. Individual-level drivers included a lack of knowledge about cervical cancer and screening literacy, and a low risk in perception, attitude, susceptibility and perceived fear of test results, as well as sociodemographic characteristics of women. Interpersonal drivers were community embarrassment, women's relationships with health workers, support and encouragement, the presence of peers or relatives to model preventive behaviour, and the mothers' networks with others. At the organizational level, influencing factors were related to providers (cervical cancer screening practice, training, providers' profession type, skill of counselling and sex, expert recommendation and work commitments). At the community level, drivers of cervical cancer screening included stigma, social-cultural norms, social networks and beliefs. System- and policy-level drivers were lack of nearby facilities and geographic remoteness, resource allocation and logistics management, cost of screening, promotion policy, ownership and management, lack of decentralized cancer policy and lack of friendly infrastructure. CONCLUSIONS: There were several drivers in the implementation of cervical cancer screening programmes at multiple levels. Prevention and management of cervical cancer programmes requires multilevel strategies to be implemented across the individual level (users), community and organizational levels (providers and community users), and system and policy levels. The design and implementation of policies and programmes need to address the multilevel challenges.

In the 1980s, heart transplantation was the first successful treatment for infants born with hypoplastic left heart syndrome. Infants who have required heart transplantation benefit from immunologic "advantages," including long-term survival free from cardiac allograft vasculopathy. Currently â¼ 90% of children undergoing a heart transplant are reaching their first-year anniversary and the clinical practices of paediatric heart transplantation have dramatically improved. These successes are largely attributed to research sponsored by the Pediatric Heart Transplant Study Group, the International Society of Heart and Lung Transplantation and, more recently, the Non-profits Enduring Hearts and Additional Ventures. Despite these successes, the field is challenged to increase progress to achieve long-term survival into adulthood. The wait-list mortality, especially among infants, is unacceptably high often leading to palliative measures that can increase post-transplant mortality. Cardiac allograft vasculopathy remains a major cause for progressive graft loss of function and sudden death. The relative tolerance seen in immature recipients has not been translated to modifying older recipients' post-transplant outcomes. The modifiable cause(s) for the increased risks of transplantation in children of different ethnicities and races require definition. Addressing these challenges faces the reality that for-profit research favours funding adult recipients, with â¼ 10-fold greater numbers, and their more modest longevity goals. Advocacy for funding "incentives" such as the Orphan Drug rules in the United States and upholding principles of equity and inclusion are critical to addressing the challenges of paediatric heart transplant recipients worldwide.

BACKGROUND: Well-designed curriculums are crucial for quality education. This study aimed to assess the implementation status of a harmonized competency-based medical curriculum (CBMC) in Ethiopia, as well as identify the associated challenges and benefits. METHODS: A mixed-method approach was used. Data collection took place from September 1, 2023, to October 15, 2023. Eleven medical schools were randomly selected from a list of 28 public medical schools in Ethiopia. Participants were purposively chosen from selected medical schools using a controlled sampling method. A total of 121 participants took part in the survey. Interviews and focus group discussions were conducted with key informants to complement the quantitative findings. Descriptive statistics, such as frequencies and percentages, were used to summarize the quantitative survey responses. Thematic content analysis was used to analyze the qualitative data. RESULTS: The implementation of a CBMC in Ethiopian public universities faces various challenges and provides opportunities. Around 22% of respondents mentioned that the whole group session (WGS) had never been implemented in their school. Regarding community-based learning (CBL), 64.6% of respondents noted that it was intermittently implemented in their institution. Only 32% of respondents considered students' clinical exposure during preclerkship years to be reasonable. Interestingly, approximately 73% of respondents stated that problem-based learning (PBL) activities were regularly conducted in their school. Around 68% of respondents believed that competency-based assessment methods were moderately utilized. While many participants perceive the curriculum as having positive content alignment and structure with intended learning outcomes, challenges related to practical sessions, resource limitations, and uneven access to training opportunities persist. Resource constraints are a prominent challenge. The opportunities identified include early clinical exposure and enhanced communication skills. CONCLUSIONS: This survey highlights the need for ongoing curriculum evaluation and fine-tuning to ensure its success.

BACKGROUND: Medical students view clinical workplace placements as an inspiring and motivating learning environment where active student participation is pivotal to development of students' identity. The progress from pre-clerkship to clerkship education harbors many challenges which consist of experiential learning, adjusting to the clinical environment, and understanding roles & responsibilities. Workplace learning is underpinned by various adult learning theories including social theories,constructivism, supported participation and legitimate peripheral participation. Workplace learning course was recently initiated for pre-clerkship students at a medical university in UAE, which will enable their smooth entry into the clerkship phase of the curriculum. OBJECTIVES: The research aims to explore students' perceptions of various domains of their clinical learning environment (CLE), highlight the challenges they face, and extract valuable feedback to improve their environment. METHODS: This study was conducted qualitatively by using focus groups method in order to explore students' perceptions of the clinical learning environment. Two focus group discussions were conducted (n = 8 +/-10) to determine the common challenges of workplace learning and its potential solutions. Data were analyzed using thematic analysis. The approach used to carry out this study was phenomenology, as it helps to understand the learning and behavior of these students who are undergoing this pre-clerkship training in order to transition smoothly to the clerkship phase. RESULT: The focus groups helped to deeply explore the perceptions of students about their clinical learning environment. It helped to reveal the challenges encountered by the students including the significance of proper orientation of staff and students, language barrier, availability of learning opportunities, and supervision quality. The focus groups provided worthwhile suggestions to improve the learning opportunities in the clinical learning environment which include orientation of the staff and students what to expect, improved supervision, mentoring and providing learning opportunities to encourage participation. CONCLUSION: This study attempted to identify the pre-clerkship students' perception of their clinical learning environment and the challenges they face over there. Possible suggestions by the students included a formal orientation for the staff and students to be carried out at the beginning. Efforts should be made by clerkship directors to provide students with learning opportunities by increasing patient exposure, encouraging participation, and providing high-quality supervision.

BACKGROUND: Morning reports are an essential component of physicians' daily work. Attending morning reports is prioritized by junior doctors as it provides them with an opportunity to learn diagnostic reasoning through discussion of cases. While teaching formats during morning reports have previously been reported, an in-depth analysis of what learning opportunities exist, e.g., how teaching is enacted during morning reports, is lacking. This qualitative study explores learning opportunities during morning reports. METHODS: We used an explorative design based on video-recordings of 23 morning reports from two surgical departments, an internal medicine department and an emergency department. We used thematic analysis combined with and inspired by Eraut's theoretical framework of workplace learning. RESULTS: Both formal and informal learning opportunities were identified. Formal learning opportunities had the character of planned teaching activities, and we identified four themes: (1) modes of teaching, (2) structure, (3) presenter role, and (4) participant involvement. Informal learning, on the other hand, was often implicit and reactive, while deliberate learning opportunities were rare. The data showed many missed opportunities for learning. CONCLUSION: Both formal and informal learning opportunities are present during morning reports. However, a prevalent focus on medical topics exists, leaving other important aspects of the medical role under-discussed. Pedagogical methods could be employed more optimally, and harnessing the potential of missed opportunities should be encouraged.

AIM: To synthesise evidence from the literature on hospital nurses' perceived challenges and opportunities in the care of people with dementia. BACKGROUND: People with dementia often have longer lengths of hospital stay and poorer health outcomes compared to those without dementia. Nurses play a pivotal role in the care of people with dementia. However, there is a scarcity of systematic reviews that synthesise the challenges and opportunities they perceive. METHODS: A mixed-methods systematic review was conducted with a database search covering Ageline, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Emcare, Embase, Medline, PsycINFO, ProQuest, Scopus and Web of Science in April 2022. In total, 27 articles that met the selection criteria were critically reviewed and included in this systematic review. Data from the selected articles were extracted and synthesised using a convergent segregated approach. RESULTS: Three main themes and eight subthemes were identified. Theme 1 described nurse-related factors consisting of the lack of capability in dementia care, experiencing multiple sources of stress and opportunities for nurses to improve dementia care. Theme 2 revealed people living with dementia-related factors including complex care needs and the need to engage family carers in care. Theme 3 explained organisation-related factors comprising the lack of organisational support for nurses and people with dementia and opportunities for quality dementia care. CONCLUSION: Hospital nurses experience multidimensional challenges in the care of people with dementia. Opportunities to overcome those challenges include organisational support for nurses to develop dementia care capability, reduce their stress and partner with the family caregivers. RELEVANCE TO CLINICAL PRACTICE: Hospitals will need to build an enabling environment for nurses to develop their capabilities in the care of people with dementia. Further research in empowering nurses and facilitating quality dementia care in acute care hospitals is needed. REPORTING METHOD: The review followed the PRISMA 2020 checklist. PATIENT OR PUBLIC CONTRIBUTION: No.

Continuing education in hematology is a key for stimulating the development around the world and improving patient outcomes. However, access to training and education is not equally distributed worldwide, and disparities in hematology exist for under-represented groups such as trainees living in low- and middle-income countries (LMICs). To identify and review the different educational and career development opportunities offered by hematology-focused international academic societies directed at healthcare professionals in this field. We conducted an online search to screen the official websites of international hematology societies and extracted data regarding continuing education opportunities in hematology. Twenty hematology societies were identified with 850 continuing medical education opportunities extracted and reviewed. We recorded 55 grants and funding opportunities from 13 societies. More than half required a membership to apply, 9.1% were available globally, and 12.7% were designed for persons living in LMICs. The current state of continuing education in hematology offers numerous opportunities for healthcare trainees. However, disparities persist for LMICs.
RESUMEN
For this CHIMIA special issue on the United Nations Sustainable Development Goals (SDGs) and the coincidental 10th anniversary of the association of Women in Natural Sciences (WiNS) at ETH Zurich, there is no better opportunity to share what we have achieved in the last decade. WiNS was originally founded by female PhD students and PostDocs at the Department of Chemistry and Applied Biosciences (D-CHAB) and has expanded to include three additional departments at ETH Zurich. Join us in celebrating our anniversary, reflecting on what we and other associations with the same mission have done to promote gender equality and reduced inequalities for all. We invite you to reflect on what yet has to be done to enact a systemic change towards achieving equal opportunities for all, rather than simply accommodating the female perspective to Switzerland's predominantly masculine working culture.
