RESUMEN

BACKGROUND: Reporting on the effect of health humanities teaching in health professions education courses to facilitate sharing and mutual exchange internationally, and the generation of a more interconnected body of evidence surrounding health humanities curricula is needed. This study asked, what could an internationally informed curriculum and evaluation framework for the implementation of health humanities for health professions education look like? METHODS: The participatory action research approach applied was based on three iterative phases 1. Perspective sharing and collaboration building. 2. Evidence gathering 3. Development of an internationally relevant curriculum and evaluation framework for health humanities. Over 2 years, a series of online meetings, virtual workshops and follow up communications resulted in the production of the curriculum framework. RESULTS: Following the perspective sharing and evidence gathering, the InspirE5 model of curriculum design and evaluation framework for health humanities in health professions education was developed. Five principal foci shaped the design of the framework. ENVIRONMENT: Learning and political environment surrounding the program. Expectations: Graduate capabilities that are clearly articulated for all, integrated into core curricula and relevant to graduate destinations and associated professional standards. EXPERIENCE: Learning and teaching experience that supports learners' achievement of the stated graduate capabilities. EVIDENCE: Assessment of learning (formative and/or summative) with feedback for learners around the development of capabilities. Enhancement: Program evaluation of the students and teachers learning experiences and achievement. In all, 11 Graduate Capabilities for Health Humanities were suggested along with a summary of common core content and guiding principles for assessment of health humanities learning. DISCUSSION: Concern about objectifying, reductive biomedical approaches to health professions education has led to a growing expansion of health humanities teaching and learning around the world. The InspirE5 curriculum and evaluation framework provides a foundation for a standardised approach to describe or compare health humanities education in different contexts and across a range of health professions courses and may be adapted around the world to progress health humanities education.

RESUMEN

BACKGROUND: The articulation of learning goals, processes and outcomes related to health humanities teaching currently lacks comparability of curricula and outcomes, and requires synthesis to provide a basis for developing a curriculum and evaluation framework for health humanities teaching and learning. This scoping review sought to answer how and why the health humanities are used in health professions education. It also sought to explore how health humanities curricula are evaluated and whether the programme evaluation aligns with the desired learning outcomes. METHODS: A focused scoping review of qualitative and mixed-methods studies that included the influence of integrated health humanities curricula in pre-registration health professions education with programme evaluate of outcomes was completed. Studies of students not enrolled in a pre-registration course, with only ad-hoc health humanities learning experiences that were not assessed or evaluated were excluded. Four databases were searched (CINAHL), (ERIC), PubMed, and Medline. RESULTS: The search over a 5 year period, identified 8621 publications. Title and abstract screening, followed by full-text screening, resulted in 24 articles selected for inclusion. Learning outcomes, learning activities and evaluation data were extracted from each included publication. DISCUSSION: Reported health humanities curricula focused on developing students' capacity for perspective, reflexivity, self- reflection and person-centred approaches to communication. However, the learning outcomes were not consistently described, identifying a limited capacity to compare health humanities curricula across programmes. A set of clearly stated generic capabilities or outcomes from learning in health humanities would be a helpful next step for benchmarking, clarification and comparison of evaluation strategy.

RESUMEN

BACKGROUND: In Norway, boys with hemophilia usually begin treatment after their first bleeding episode. Boys with severe hemophilia usually start prophylactic treatment around 18-24 months. Health professionals administer factor concentrate initially, but when boys are around 4 years old most parents start treating their children at home. There is a lack of research on how parents, and especially how carrier mothers, experience the medical treatment for their sons' hemophilia. Our aim was to investigate how carrier mothers experience this treatment in the hospital setting and at home. METHODS: In this qualitative study, we interviewed 16 mothers of boys or men with hemophilia A or B. Data were collected via semistructured interviews and analyzed using an inductive thematic analytical approach. RESULTS: Mothers experienced both practical and emotional challenges in relation to their sons' treatment, and repeated venipuncture was especially difficult emotionally. Parents preferred home treatment to hospital treatment because it was less time-consuming, less disruptive to family life, and provided a greater sense of control. Encountering healthcare professionals who were unfamiliar with hemophilia was a second major stress factor, especially when parents felt that health professionals lacked competence and were unwilling to seek advice. CONCLUSION: While home treatment for hemophilia enables freedom, flexibility, and autonomy for the boys as well as for the family, mothers may experience treatment of hemophilia as a burden. Health professionals should provide tailored practical and emotional support to parents by probing into their experiences with treating their sons' hemophilia.

RESUMEN

Studies on carriers of genetic disorders mainly focus on the process of genetic testing and reproductive choices, and less on how psychosocial aspects of being a carrier change over time. Our study sought to understand more about the psychosocial aspects of hemophilia carrier status, and thereby improve counseling aiming to advance carriers' quality of life and well-being. We analyzed 16 in-depth interviews from women who were carriers of hemophilia and had a son with hemophilia. Three themes emerged: Guilt and sorrow across generations; the choices and future consequences of genetic testing; and preparing to have a child with hemophilia. Experience with being a hemophilia carrier is a process that changes over time while feelings of guilt and sorrow run across generations. The carrier status may create "mothers-in-waiting" living at risk of having a sick child or not. The women think they are prepared to have a son with hemophilia, but experience more sadness than they expect when a son is diagnosed. Our findings suggest that health professionals, especially clinical geneticists and genetic counselors, carriers, families and patient organizations need to be aware that women's experiences of being a carrier of hemophilia changes during the biographical life course. The women may benefit from several rounds of genetic counseling at different stages of life.

RESUMEN

INTRODUCTION: There has been little qualitative research examining how physical examination skills are learned, particularly the sensory and subjective aspects of learning. The authors set out to study how medical students are taught and learn the skills of listening to sound. METHODS: As part of an ethnographic study in Melbourne, 15 semi-structured in-depth interviews were conducted with students and teachers as a way to reflect explicitly on their learning and teaching. RESULTS: From these interviews, we found that learning the skills of listening to lung sounds was frequently difficult for students, with many experiencing awkwardness, uncertainty, pressure, and intimidation. However not everyone found this process difficult. Often those who had studied music reported finding it easier to be attentive to the frequency and rhythm of body sounds and find ways to describe them. CONCLUSIONS: By incorporating, distinctively in medical education, theoretical insights into "attentiveness" from anthropology and science and technology studies, the article suggests that musical education provides medical students with skills in sensory awareness. Training the senses is a critical aspect of diagnosis that needs to be better addressed in medical education. Practical approaches for improving students' education of attention are proposed.

RESUMEN

We investigated the diversity of Bartonella in Apodemus agrarius, an important rodent of peri-domestic habitats, which has spread into Europe in the past 1000 years. Spleen samples of 344 A. agrarius from Eastern Slovakia were screened for the presence of Bartonella spp. using 16S-23S rRNA internal transcribed spacer region and bacteria were detected in 9% of rodents. Based on sequencing of three housekeeping genes (gltA, rpoB and groEL) Bartonella genotypes were ascribed to the species typical for mice and voles: B. grahamii, B. taylorii and B. birtlesii. However, the study also confirmed presence of genotypes belonging to the B. clarridgeiae/B. rochalimae clade, and the B. elizabethae/B. tribocorum clade, which are not commonly found in woodland rodents. In addition, a potential recombination event between these two genotypes was noted, which highlights an important role of A. agrarius in shaping Bartonella diversity and evolution.

RESUMEN

Little is known about the experiences of women with Fabry disease. The aim of this study was to explore women's experiences of being heterozygous for Fabry disease. We used an explorative qualitative study design and selected ten Norwegian women who were known heterozygous for Fabry disease to participate. We conducted in-depth semi-structured interviews and analyzed the interviews using inductive thematic analysis. We found that learning about one's heterozygous status may be devastating for some. However, for most of the participants, heterozygous status, as well as doctors' acceptance of symptoms in women heterozygous for Fabry disease, provided an explanation and relief. Although many women did not consider themselves ill, they wished to be acknowledged as more than "just carriers." The participants were grateful for enzyme replacement therapy, although it had its burdens regarding time, planning, and absences from school or work. Women with Fabry disease felt that the lack of knowledge among healthcare professionals about Fabry disease was frustrating and worrisome. These findings suggest that healthcare professionals should acknowledge the different ways women react to their diagnosis, and be aware of the personal costs of receiving treatment.

RESUMEN

Cryptosporidium is an important waterborne pathogen for which no treatment or vaccination is available. This study set out to quantify DNA replication of Cryptosporidium parvum in vitro. Cryptosporidium DNA could be detected at up to 60 % of input level in both host-cell-free and host cell containing cultures 6 days after infection with living sporozoites, but was lost within 2 days in cultures inoculated with UV-inactivated sporozoites. Total DNA increased between days 2 and 6, evidence of successful DNA replication in both cell-free and host-cell-containing cultures. Overall however, only a small fraction (up to 5 %) of parasite DNA could be found associated with host cells or bound to plastic of the cell-free cultures, and the majority of parasite DNA was present in the cell culture medium, separable by simple decantation. After 2 days, in host-cell-containing cultures, the parasite DNA could be concentrated by slow centrifugation, suggesting that it was associated with intact parasite cells, but at 6 days, the majority could not be centrifuged and is therefore thought to have represented copies associated with dead and degraded parasites. In cell-free cultures and in larger plates, the majority of DNA was in this form. Performance of the parasite was best in small culture plates, and least in the largest plate sizes. We interpret these results as suggesting that Cryptosporidium sporozoites first bind to the host cell monolayer or to the plasticware, but then by 2 days, there has been a substantial release of parasites back into the medium. Host-cell-free cultures also supported modest replication and may have represented DNA synthesis in cells beginning merogony. The role of the host cells is unclear, as so much of the parasite DNA is released into the medium. Host cells may provide a feeder role, conditioning the medium for Cryptosporidium development.

RESUMEN

Osteosarcoma (OSA) is the most common type of primary bone malignancy in people and dogs. Our previous molecular comparisons of canine OSA against healthy bone resulted in the identification of differentially expressed protein-expressing genes (forkhead box protein O4 (FOXO4), interferon regulatory factor 8 (IRF8), and lymphoid enhancer binding factor 1 (LEF1)). Immunohistochemistry (IHC) and H-scoring provided semi-quantitative assessment of nuclear and cytoplasmic staining alongside qualitative data to contextualise staining (n = 26 patients). FOXO4 was expressed predominantly in the cytoplasm with significantly lower nuclear H-scores. IRF8 H-scores ranged from 0 to 3 throughout the cohort in the nucleus and cytoplasm. LEF1 was expressed in all patients with significantly lower cytoplasmic staining compared to nuclear. No sex or anatomical location differences were observed. While reduced levels of FOXO4 might indicate malignancy, the weak or absent protein expression limits its primary use as diagnostic tumour marker. IRF8 and LEF1 have more potential for prognostic and diagnostic uses and facilitate further understanding of their roles within their respective molecular pathways, including Wnt/beta-catenin/LEF1 signalling and differential regulation of tumour suppressor genes. Deeper understanding of the mechanisms involved in OSA are essential contributions towards the development of novel diagnostic, prognostic, and treatment options in human and veterinary medicine contexts.

RESUMEN

Phytophthora pseudosyringae is a self-fertile pathogen of woody plants, particularly associated with tree species from the genera Fagus, Notholithocarpus, Nothofagus and Quercus, which is found across Europe and in parts of North America and Chile. It can behave as a soil pathogen infecting roots and the stem collar region, as well as an aerial pathogen infecting leaves, twigs and stem barks, causing particular damage in the United Kingdom and western North America. The population structure, migration and potential outcrossing of a worldwide collection of isolates were investigated using genotyping-by-sequencing. Coalescent-based migration analysis revealed that the North American population originated from Europe. Historical gene flow has occurred between the continents in both directions to some extent, yet contemporary migration is overwhelmingly from Europe to North America. Two broad population clusters dominate the global population of the pathogen, with a subgroup derived from one of the main clusters found only in western North America. Index of association and network analyses indicate an influential level of outcrossing has occurred in this preferentially inbreeding, homothallic oomycete. Outcrossing between the two main population clusters has created distinct subgroups of admixed individuals that are, however, less common than the main population clusters. Differences in life history traits between the two main population clusters should be further investigated together with virulence and host range tests to evaluate the risk each population poses to natural environments worldwide.

RESUMEN

BACKGROUND: N6-methyladenosine (m6A) is the most common internal RNA modification and is involved in regulation of RNA and protein expression. AlkB family member 5 (ALKBH5) is a m6A demethylase. Given the important role of m6A in biological mechanisms, m6A and its regulators, have been implicated in many disease processes, including cancer. However, the contribution of ALKBH5 to invasive breast cancer (BC) remains poorly understood. The aim of this study was to evaluate the clinicopathological value of ALKBH5 in BC. METHODS: Publicly available data were used to investigate ALKBH5 mRNA alterations, prognostic significance, and association with clinical parameters at the genomic and transcriptomic level. Differentially expressed genes (DEGs) and enriched pathways with low or high ALKBH5 expression were investigated. Immunohistochemistry (IHC) was used to assess ALKBH5 protein expression in a large well-characterised BC series (n = 1327) to determine the clinical significance and association of ALKBH5 expression. RESULTS: Reduced ALKBH5 mRNA expression was significantly associated with poor prognosis and unfavourable clinical parameters. ALKBH5 gene harboured few mutations and/or copy number alternations, but low ALKBH5 mRNA expression was seen. Patients with low ALKBH5 mRNA expression had a number of differentially expressed genes and enriched pathways, including the cytokine-cytokine receptor interaction pathway. Low ALKBH5 protein expression was significantly associated with unfavourable clinical parameters associated with tumour progression including larger tumour size and worse Nottingham Prognostic Index group. CONCLUSION: This study implicates ALKBH5 in BC and highlights the need for further functional studies to decipher the role of ALKBH5 and RNA m6A methylation in BC progression.

RESUMEN

Prostate cancer (PCa) is the second most common cancer diagnosed in men. While radical prostatectomy and radiotherapy are often successful in treating localised disease, post-treatment recurrence is common. As the androgen receptor (AR) and androgen hormones play an essential role in prostate carcinogenesis and progression, androgen deprivation therapy (ADT) is often used to deprive PCa cells of the pro-proliferative effect of androgens. ADTs act by either blocking androgen biosynthesis (e.g. abiraterone) or blocking AR function (e.g. bicalutamide, enzalutamide, apalutamide, darolutamide). ADT is often effective in initially suppressing PCa growth and progression, yet emergence of castrate-resistant PCa and progression to neuroendocrine-like PCa following ADT are major clinical challenges. For this reason, there is an urgent need to identify novel approaches to modulate androgen signalling to impede PCa progression whilst also preventing or delaying therapy resistance. The mechanistic convergence of androgen and epitranscriptomic signalling offers a potential novel approach to treat PCa. The epitranscriptome involves covalent modifications of mRNA, notably, in the context of this review, the N(6)-methyladenosine (m6A) modification. m6A is involved in the regulation of mRNA splicing, stability, and translation, and has recently been shown to play a role in PCa and androgen signalling. The m6A modification is dynamically regulated by the METTL3-containing methyltransferase complex, and the FTO and ALKBH5 RNA demethylases. Given the need for novel approaches to treat PCa, there is significant interest in new therapies that target m6A that modulate AR expression and androgen signalling. This review critically summarises the potential benefit of such epitranscriptomic therapies for PCa patients.

RESUMEN

BACKGROUND: Paediatric convulsive status epilepticus is the most common neurological emergency presenting to emergency departments. Risks of resultant neurological morbidity and mortality increase with seizure duration. If the seizure fails to stop within defined time-windows, standard care follows an algorithm of stepwise escalation to more intensive treatments, ultimately resorting to induction of general anaesthesia and ventilation. Additionally, ventilatory support may also be required to treat respiratory depression, a common unwanted effect of treatment. There is strong pre-clinical evidence that pH (acid-base balance) is an important determinant of seizure commencement and cessation, with seizures tending to start under alkaline conditions and terminate under acidic conditions. These mechanisms may be particularly important in febrile status epilepticus: prolonged fever-related seizures which predominantly affect very young children. This trial will assess whether imposition of mild respiratory acidosis by manipulation of inhaled medical gas improves response rates to first-line medical treatment. METHODS: A double-blind, placebo-controlled trial of pH manipulation as an adjunct to standard medical treatment of convulsive status epilepticus in children. The control arm receives standard medical management whilst inhaling 100% oxygen; the active arm receives standard medical management whilst inhaling a commercially available mixture of 95% oxygen, 5% carbon dioxide known as 'carbogen'. Due to the urgent need to treat the seizure, deferred consent is used. The primary outcome is success of first-line treatment in seizure cessation. Planned subgroup analyses will be undertaken for febrile and non-febrile seizures. Secondary outcomes include rates of induction of general anaesthesia, admission to intensive care, adverse events, and 30-day mortality. DISCUSSION: If safe and effective 95% oxygen, 5% carbon dioxide may be an important adjunct in the management of convulsive status epilepticus with potential for pre-hospital use by paramedics, families, and school staff.

RESUMEN

Infections with Bartonella spp. have been recognized as emerging zoonotic diseases in humans. Large knowledge gaps exist, however, relating to reservoirs, vectors, and transmission of these bacteria. We describe identification by culture, PCR, and housekeeping gene sequencing of Bartonella spp. in fed, wingless deer keds (Lipoptena cervi), deer ked pupae, and blood samples collected from moose, Alces alces, sampled within the deer ked distribution range in Norway. Direct sequencing from moose blood sampled in a deer ked-free area also indicated Bartonella infection but at a much lower prevalence. The sequencing data suggested the presence of mixed infections involving two species of Bartonella within the deer ked range, while moose outside the range appeared to be infected with a single species. Bartonella were not detected or cultured from unfed winged deer keds. The results may indicate that long-term bacteremia in the moose represents a reservoir of infection and that L. cervi acts as a vector for the spread of infection of Bartonella spp. Further research is needed to evaluate the role of L. cervi in the transmission of Bartonella to animals and humans and the possible pathogenicity of these bacteria for humans and animals.

RESUMEN

We report a 33-year-old female with cutaneous involvement by Churg-Strauss syndrome confined to surgical scars that were obtained 13 years before. She presented to the emergency department with 2-day history of fever, night sweats, right-sided weakness, hoarseness and worsening asthma symptoms. She was found to have an eosinophilia and two sub-5-mm pulmonary nodules. The patient also reported that the scars on her right thumb, inner wrist and back had been swollen, red and painful for 2 days. Examination revealed tender, erythematous, well-healed edematous scars studded with small skin colored papules. She had no clinical findings that were classic for cutaneous vasculitis. A skin biopsy of a scar revealed perivascular and palisading granulomatous inflammation consisting of histiocytes and neutrophils with leukocytoclasia. Focal vascular injury was identified. Scattered tissue eosinophils were seen. Special stains were negative for infection. Thereafter, she was started on intravenous steroids, at which point the fever, pulmonary and cutaneous symptoms subsided. Although scar sarcoidosis is a well-described phenomenon, granulomatous inflammation and vasculitis seen in Churg-Strauss syndrome exclusively manifesting in well-healed surgical scars highlights the unique features seen in this case and draws attention to the concept of locus minoris resistentiae. This case also highlights how a skin biopsy in the setting of suspected systemic vasculitis can confirm the presence of vasculitis and/or granulomatous inflammation and obviate the need for more invasive, higher risk procedures such as lung biopsy.

RESUMEN

Individuals now have access to an increasing number of internet resources offering personal genomics services. As the direct-to-consumer genetic testing (DTC GT) industry expands, critics have called for pre- and post-test genetic counseling to be included with the product. Several genetic testing companies offer genetic counseling. There has been no examination to date of this service provision, whether it meets critics' concerns and implications it may have for the genetic counseling profession. Considering the increasing relevance of genetics in healthcare, the complexity of genetic information provided by DTC GT, the mediating role of the internet in counseling, and potential conflicts of interest, this is a topic which deserves further attention. In this paper we offer a discourse analysis of ways in which genetic counseling is represented on DTC GT websites, blogs and other online material. This analysis identified four types of genetic counseling represented on the websites: the integrated counseling product; discretionary counseling; independent counseling; and product advice. Genetic counselors are represented as having the following roles: genetics educator; mediator; lifestyle advisor; risk interpreter; and entrepreneur. We conclude that genetic counseling as represented on DTC GT websites demonstrates shifting professional roles and forms of expertise in genetic counseling. Genetic counselors are also playing an important part in how the genetic testing market is taking shape. Our analysis offers important and timely insights into recent developments in the genetic counseling profession, which have relevance for practitioners, researchers and policy makers concerned with the evolving field of personal genomics.

RESUMEN

Medical schools are important nodes in the reproduction of medical knowledge, and an often-visited field site for medical anthropologists. To date, the spotlight has been on teachers, students and (simulated) patients. I broaden this focus to look at the practices of medical school secretaries, porters and other staff, investigating the embodied effects of their "invisible work." Drawing from ethnographic fieldwork in a Dutch medical school, I mobilize the more multisensory term "shadow work" to understand how such practices become part of medical students' future clinical practices through highlighting, isolating, and exaggerating, necessary elements of their medical education.

RESUMEN

BACKGROUND: Indocyanine green (ICG) fluoresces in the near infra-red (NIR) spectrum. It is widely used in adult oncological surgery for identification of tumor margins and lymph node sampling. However, deliver of ICG in almost all studies is 24 h or more prior to surgery. This is the first study in children to assess its feasibility in minimally invasive surgery (MIS) for oncological disease following ICG injection during induction of anesthesia. METHODS: This was an open label, prospective, single center, feasibility study recruiting consecutive patients eligible for MIS tumor resection or metastectomy. ICG was injected intravenously at induction of anesthesia. Patient demographics, intraoperative appearances, post-operative histopathology, and surgeon Likert ratings were collected. RESULTS: Fourteen patients were included. Five had lung metastases (Wilms, Osteosarcoma (2), Hodgkin's, melanoma) and 9 had other tumors (neuroblastoma, inflammatory myofibroblastic tumor, ganglioneuroma, phaeochromocytoma, adrenal tumor). Lung metastases were easily identifiable, and all had negative margins. Tumors containing viable disease fluoresced and were completely resected, whilst benign and heavily treated tumors were afluorescent. There were no adverse events relating to ICG or issues with background fluorescence. CONCLUSION: Based on this small sample, injection of ICG during induction of anesthesia is safe and effective in showing tumor margins in patients who have had little or no neoadjuvant chemotherapy as well as in metastectomy in Wilms and osteosarcoma. Further studies are needed to confirm these preliminary results.

RESUMEN

PURPOSE: To describe a Medical School Applicant Workshop (MSAW); present lessons learned about its impact on American Indian/Alaska Native (AIAN) participants' knowledge, confidence, and sense of community; and report on participants' medical school application progress 1 year after workshop completion. METHOD: The Northwest Native American Center of Excellence at Oregon Health & Science University developed and implemented an annual 1-day AIAN MSAW in 2018. The main objectives of the workshop are for participants to gain insights into the medical school application process; learn strategies to competitively apply; receive feedback on their personal statement and mock interviews; and discuss the medical school application process with AIAN faculty, admissions deans, and peer-mentors. Recruitment of AIAN participants occurred via email; social media; text messaging; medical association contacts; and AIAN and science, technology, engineering, and mathematics organizations. Two surveys were administered: one immediately after and another 1-year after the workshop. RESULTS: Forty AIAN MSAW participants were accepted in 2018-2020. Findings indicate statistically significant increases in participants' self-reported knowledge of the medical school application process and in their self-reported confidence. Participants reported meeting other AIAN students was highly beneficial and feeling connected to a community of AIAN health professionals after attending the workshop. Among the 25 participants who completed the 1-year follow-up survey, 12 (48.0%) indicated applying to medical school; all 12 of these participants were invited to interview, and 11 were offered acceptance to at least one medical school. CONCLUSIONS: Completing the MSAW increased participants' knowledge, confidence, and sense of community. If other programs and institutions were to consider using the MSAW model to reduce barriers and provide supports specifically designed for AIANs before and during the medical school application process, medical schools may stand to further increase AIAN representation in the physician workforce and ultimately to decrease health inequities among AIANs.
