RESUMO
We present a case of a 6-week-old infant who presented with seizure-like activity. Workup revealed abnormal coagulation and imaging confirmed intracranial hemorrhage. Parental refusal of vitamin K treatment at birth suggested vitamin K deficiency bleeding (VKDB) in this newborn. Though VKDB is rare in developed countries, rates have been rising which coincides with an increasing trend of parental refusal of vitamin K prophylaxis at birth.

BACKGROUND: In Nigeria, many men and women from different socioeconomic classes, commonly incur expenses in the pursuit of lighter skin. This recurrent expenditure and the associated costs of the alternative foregone as well as added costs associated with management of the adverse effects have the capacity to negatively impact on the finances of individuals and households who engage in skin lightening practices. OBJECTIVES: This study aimed to identify the sociodemographic characteristics of respondents in Benin City, Nigeria, determine the prevalence of the skin lightening practices among these respondents and explore the financial implications of these practices. METHODS: A cross-sectional community-based survey using pretested structured questionnaires was conducted on 454 men and women aged 18-70 years selected via multistage sampling in Oredo local government area of Benin city, Edo state, Nigeria. RESULTS: There were 207 males and 247 females included in the survey. Of these 55.3 % were currently using skin lightening products. The average monthly expenditure on cosmetics was significantly higher for users of skin lightening agents (Mean = N==2,183.13, SD = 2,822.91) compared to respondents who did not use skin lightening agents (Mean = =N=1,292.91, SD =1,379.43) (p < 0.001). Cost was the least common factor (2.5%) observed to influence respondents' purchase of skin lightening agents while recommendations from friends and family (59.2%) was the most common factor observed to influence their purchase. Majority of respondents engaged in this practice (77.5%) had seen a doctor or health worker for treatment of a skin problem that occurred during the use of skin lightening agents. CONCLUSION: Engaging in skin lightening practices was done by more than half of the respondents regardless of the cost of the agents and socioeconomic class, with the average monthly expenditure on cosmetics being significantly higher for users of skin lightening agents. This has the potential to negatively impact on the socioeconomic status of the individuals, households and the Nigerian economy over time.
CONTEXTE: Au Nigeria, beaucoup d'hommes et de femmes de différentes classes socio-économiques engagent des dépenses pour obtenir une peau plus claire. Ces dépenses récurrentes et les coûts associés à l'alternative abandonnée ainsi que les coûts supplémentaires associés à la gestion des effets indésirables ont la capacité d'avoir un impact négatif sur les finances des individus et des ménages qui s'engagent dans des pratiques d'éclaircissement de la peau. OBJECTIFS: Cette étude visait à identifier les caractéristiques sociodémographiques des personnes interrogées à Benin City, au Nigeria, à déterminer la prévalence des pratiques d'éclaircissement de la peau parmi ces personnes et à explorer les implications financières de ces pratiques. MÉTHODES: Une enquête communautaire transversale utilisant des questionnaires structurés prétestés a été menée auprès de 454 hommes et femmes âgés de 18 à 70 ans sélectionnés par échantillonnage à plusieurs degrés dans la zone de gouvernement local d'Oredo de la ville de Benin, dans l'État d'Edo, au Nigeria. RÉSULTATS: L'enquête a porté sur 207 hommes et 247 femmes. Parmi eux, 55,3 % utilisaient actuellement des produits d'éclaircissement de la peau. Les dépenses mensuelles moyennes en cosmétiques étaient significativement plus élevées pour les utilisateurs d'agents éclaircissants pour la peau (Moyenne = ¦ 2 183,13, ET = 2 822,91) par rapport aux répondants qui n'utilisaient pas d'agents éclaircissants pour la peau (Moyenne = ¦ 1 292,91, ET = 1 379,43) (p < 0,001). Le coût était le facteur le moins courant (2,5 %) observé pour influencer l'achat d'agents éclaircissants pour la peau par les répondants, tandis que les recommandations des amis et de la famille (59,2 %) étaient le facteur le plus courant observé pour influencer leur achat. La majorité des répondants engagés dans cette pratique (77,5 %) avaient consulté un médecin ou un agent de santé pour le traitement d'un problème de peau survenu lors de l'utilisation d'agents éclaircissants. CONCLUSION: Plus de la moitié des personnes interrogées s'adonnent à des pratiques d'éclaircissement de la peau, indépendamment du coût des agents et de la classe socio-économique, les dépenses mensuelles moyennes en cosmétiques étant significativement plus élevées pour les utilisateurs d'agents d'éclaircissement de la peau. Cela peut avoir un impact négatif sur le statut socio-économique des individus, des ménages et de l'économie nigériane au fil du temps.

BACKGROUND: A previous analysis of 113 National Comprehensive Cancer Network® (NCCN®) recommendations reported that NCCN frequently recommends beyond Food and Drug Administration (FDA)-approved indications (44 off-label recommendations) and claimed that the evidence for these recommendations was weak. METHODS: In order to determine the strength of the evidence, we carried out an in-depth re-analysis of the 44 off-label recommendations listed in the NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines®). RESULTS: Of the 44 off-label recommendations, 14 were later approved by the FDA and/or are supported by randomized controlled trial (RCT) data. In addition, 13 recommendations were either very minor extrapolations from the FDA label (n = 8) or were actually on-label (n = 5). Of the 17 remaining extrapolations, 8 were for mechanism-based agents applied in rare cancers or subsets with few available treatment options (median response rate = 43%), 7 were based on non-RCT data showing significant efficacy (>50% response rates), and 2 were later removed from the NCCN Guidelines because newer therapies with better activity and/or safety became available. CONCLUSION: Off-label drug use is a frequent component of care for patients with cancer in the United States. Our findings indicate that when the NCCN recommends beyond the FDA-approved indications, the strength of the evidence supporting such recommendations is robust, with a significant subset of these drugs later becoming FDA approved or supported by RCT. Recommendations without RCT data are often for mechanism-based drugs with high response rates in rare cancers or subsets without effective therapies.

BACKGROUND: Colonoscopy is the standard of care for the diagnosis and treatment of many colonic disorders. Over the past few years, endoscopic closure of colonoscopy-related perforation has become more common. Endoscopic closure of perforation secondary to colonoscopy has been undertaken in patients in the hospital setting and often during the same colonoscopic procedure in which the perforation itself occurred. The aim of our study was to analyze our experience with emergency endoscopic closure of colonoscopy-related perforation with over-the-scope clip (OTSC) technique. METHODS: We report five cases of colonic perforation that occurred during colonoscopy in an outpatient facility remotely located from our hospital and then referred as an emergency to our institution for endoscopic closure. RESULTS: Bowel preparation was reported to be adequate in all cases. Prior to attempting endoscopic closure of colonic perforation, all patients were in stable clinical condition, early broad-spectrum antibiotic coverage was initiated, and a surgical consult was obtained. All patients had sigmoidoscopy and were found to have sigmoid colon perforations. In three cases, the perforations were closed successfully using an OTSC clip device 14 mm type t. Two patients were found to have greater than 4-cm sigmoid perforations with irregular margins, incompatible with OTSC closure, and were referred for emergency surgery. All patients had an uneventful course following either OTSC closure or surgery. CONCLUSIONS: Based on the characteristics of the five cases and a review of the literature, we suggest a practical approach for undertaking closure of colonic perforations occurring during colonoscopy in the outpatient setting, focusing on clinical criteria to determine eligibility of patients for attempted endoscopic closure and outlining required therapeutic and monitoring steps needed to optimize outcomes.

OBJECTIVE: To determine the microarchitecture of the cervix using high-resolution diffusion tensor (DT) magnetic resonance imaging (MRI). DESIGN: Cross-sectional study. SETTING: Leeds, UK. SAMPLE: Women undergoing hysterectomy for benign pathology. METHODS: Ex-vivo DT-MRI measurements were obtained using a 9.4-T Bruker nuclear magnetic resonance (NMR) spectrometer on seven fixed human cervices obtained at hysterectomy. A deterministic fibre-tracking algorithm was used to indirectly visualise underlying fibre organisation. Inter-regional differences in tissue structure were sought using quantitative measurements of diffusion. MAIN OUTCOME MEASURE: The identification of an occlusive structure in the region corresponding to the internal cervical os. RESULTS: Fibre tracking demonstrated two regions: an outer circular and inner longitudinal layer. The total circumferential tract volume (TV) was greatest in the proximal region of the cervix (TV: proximal, 271 ± 198 mm3 ; middle, 186 ± 119 mm3 ; distal, 38 ± 36 mm3 ). Fractional anisotropy (FA) and apparent diffusion coefficient (ADC) measurements were significantly different between regions in all samples (P < 0.0005), indicating greater tract density and organisation towards the internal os. CONCLUSION: Fibre tracking infers a system of dense, well-defined, encircling fibres in the proximal region of the cervix, corresponding to the location of the internal os. These findings may provide evidence of specific anatomic microarchitecture within the cervix able to resist intrauterine forces associated with pregnancy. TWEETABLE ABSTRACT: Diffusion-tensor MRI derived tractography identified well-defined encircling fibres at the internal os.

NGC 4449 is a nearby Magellanic irregular starburst galaxy with a B-band absolute magnitude of -18 and a prominent, massive, intermediate-age nucleus at a distance from Earth of 3.8 megaparsecs (ref. 3). It is wreathed in an extraordinary neutral hydrogen (H I) complex, which includes rings, shells and a counter-rotating core, spanning â¼90 kiloparsecs (kpc; refs 1, 4). NGC 4449 is relatively isolated, although an interaction with its nearest known companion--the galaxy DDO 125, some 40 kpc to the south--has been proposed as being responsible for the complexity of its H I structure. Here we report the presence of a dwarf galaxy companion to NGC 4449, namely NGC 4449B. This companion has a V-band absolute magnitude of -13.4 and a half-light radius of 2.7 kpc, with a full extent of around 8 kpc. It is in a transient stage of tidal disruption, similar to that of the Sagittarius dwarf near the Milky Way. NGC 4449B exhibits a striking S-shaped morphology that has been predicted for disrupting galaxies but has hitherto been seen only in a dissolving globular cluster. We also detect an additional arc or disk ripple embedded in a two-component stellar halo, including a component extending twice as far as previously known, to about 20 kpc from the galaxy's centre.
RESUMO
In this article, we discuss the challenges facing humanities researchers approaching studies in clinical and community health settings. This crossing of disciplines has arguably been less often explored in the countries we discuss-Kenya, Tanzania and South Africa-but our experiences also speak to broader trouble with disciplinary 'ethnocentrism' that hampers the development of knowledge. After a brief contextualising overview of the structures within our universities that separate or link the humanities, medicine and social science, we use case studies of our experiences as an arts researcher, an anthropologist and a historian to draw attention to the methodological clashes that can hobble research between one disciplinary area and another, whether this manifests in the process of applying for ethical clearance or a professional wariness between healthcare practitioners and humanities scholars in health spaces. We argue overall for the great potential of humanities in the health 'space'-as well as the need for improved dialogue between the disciplines to bring a diverse community of knowledge to bear on our understandings of experiences of health. And we suggest the need for a robust awareness of our own positions in relation to medicine, as humanities scholars, as well as a patient persistence on both sides of the humanities-health science equation to create a broader and ultimately more effective research system.

Background: In respect of the principle of autonomy and the right of self-determination, obtaining an informed consent of potential participants before their inclusion in a study is a fundamental ethical obligation. The variations in national laws, regulations, and cultures contribute to complex informed consent documents for patients participating in clinical trials. Currently, only few ethics committees seem willing to address the complexity and the length of these documents and to request investigators and sponsors to revise them in a way to make them understandable for potential participants. The purpose of this work is to focus on the written information in the informed consent documentation for drug development clinical trials and suggests (i) to distinguish between necessary and not essential information, (ii) to define the optimal format allowing the best legibility of those documents. Methods: The Aide et Recherche en Cancérologie Digestive (ARCAD) Group, an international scientific committee involving oncologists from all over the world, addressed these issues and developed and uniformly accepted a simplified informed consent documentation for future clinical research. Results: A simplified form of informed consent with the leading part of 1200-1800 words containing all of the key information necessary to meet ethical and regulatory requirements and 'relevant supportive information appendix' of 2000-3000 words is provided. Conclusions: This position paper, on the basis of the ARCAD Group experts discussions, proposes our informed consent model and the rationale for its content.

BACKGROUND: Observational studies suggest that higher levels of 25-hydroxyvitamin D3 (25(OH)D) are associated with a reduced risk of colorectal cancer and improved survival of colorectal cancer patients. However, the influence of vitamin D status on cancer recurrence and survival of patients with stage III colon cancer is unknown. PATIENTS AND METHODS: We prospectively examined the influence of post-diagnosis predicted plasma 25(OH)D on outcome among 1016 patients with stage III colon cancer who were enrolled in a National Cancer Institute-sponsored adjuvant therapy trial (CALGB 89803). Predicted 25(OH)D scores were computed using validated regression models. We examined the influence of predicted 25(OH)D scores on cancer recurrence and mortality (disease-free survival; DFS) using Cox proportional hazards. RESULTS: Patients in the highest quintile of predicted 25(OH)D score had an adjusted hazard ratio (HR) for colon cancer recurrence or mortality (DFS) of 0.62 (95% confidence interval [CI], 0.44-0.86), compared with those in the lowest quintile (Ptrend = 0.005). Higher predicted 25(OH)D score was also associated with a significant improvement in recurrence-free survival and overall survival (Ptrend = 0.01 and 0.0004, respectively). The benefit associated with higher predicted 25(OH)D score appeared consistent across predictors of cancer outcome and strata of molecular tumor characteristics, including microsatellite instability and KRAS, BRAF, PIK3CA, and TP53 mutation status. CONCLUSION: Higher predicted 25(OH)D levels after a diagnosis of stage III colon cancer may be associated with decreased recurrence and improved survival. Clinical trials assessing the benefit of vitamin D supplementation in the adjuvant setting are warranted. CLINICALTRIALS.GOV IDENTIFIER: NCT00003835.

Traditionally, the efficacy of cancer treatment in patients with advance or metastatic disease in clinical studies has been studied using overall survival and more recently tumor-based end points such as progression-free survival, measurements of response to treatment. However, these seem not to be the relevant clinical end points in current situation if such end points were no validated as surrogate of overall survival to demonstrate the clinical efficacy. Appropriate, meaningful, primary patient-oriented and patient-reported end points that adequately measure the effects of new therapeutic interventions are then crucial for the advancement of clinical research in metastatic colorectal cancer to complement the results of tumor-based end points. Health-related quality of life (HRQoL) is effectively an evaluation of quality of life and its relationship with health over time. HRQoL includes the patient report at least of the way a disease or its treatment affects its physical, emotional and social well-being. Over the past few years, several phase III trials in a variety of solid cancers have assessed the incremental value of HRQoL in addition to the traditional end points of tumor response and survival results. HRQoL could provide not only complementary clinical data to the primary outcomes, but also more precise predictive and prognostic value. This end point is useful for both clinicians and patients in order to achieve the dogma of precision medicine. The present article examines the use of HRQoL in phase III metastatic colorectal cancer clinical trials, outlines the importance of HRQoL assessment methods, analysis, and results presentation. Moreover, it discusses the relevance of including HRQoL as a primary/co-primary end point to support the progression-free survival results and to assess efficacy of treatment in the advanced disease setting.

AIMS: The objective of this study was to determine if the faecal microbiome has an association with Escherichia coli O157:H7 prevalence and enumeration. METHODS AND RESULTS: Pyrosequencing analysis of faecal microbiome was performed from feedlot cattle fed one of three diets: (i) 94 heifers fed low concentrate (LC) diet, (ii) 142 steers fed moderate concentrate (MC) diet, and (iii) 132 steers fed high concentrate (HC) diet. A total of 322 585 OTUs were calculated from 2,411,122 high-quality sequences obtained from 368 faecal samples. In the LC diet group, OTUs assigned to the orders Clostridiales and RF39 (placed within the class Mollicutes) were positively correlated with both E. coli O157:H7 prevalence and enumeration. In the MC diet group, OTUs assigned to Prevotella copri were positively correlated with both E. coli O157:H7 prevalence and enumeration, whereas OTUs assigned to Prevotella stercorea were negatively correlated with both E. coli O157:H7 prevalence and enumeration. In both the MC diet group and the HC diet group, OTUs assigned to taxa placed within Clostridiales were both positively and negatively correlated with both E. coli O157:H7 prevalence and enumeration. However, all correlations were weak. In both the MC diet group and the HC diet group, stepwise linear regression through backward elimination analyses indicated that these OTUs were significantly correlated (P < 0·001) with prevalence or enumeration, explaining as much as 50% of variability in E. coli O157:H7 prevalence or enumeration. CONCLUSIONS: Individual colonic bacterial species have little impact on E. coli O157:H7 shedding but collectively groups of bacteria were strongly associated with pathogen shedding. SIGNIFICANCE AND IMPACT OF THE STUDY: Bacterial groups in the bovine colon may impact faecal shedding of the zoonotic pathogen E. coli O157:H7, and manipulation of the intestinal microbiota to alter these bacteria may reduce shedding of this pathogen and foodborne illnesses.

Colorectal cancer (CRC) is one of the most common malignancies in Western countries. Over the last 20 years, and the last decade in particular, the clinical outcome for patients with metastatic CRC (mCRC) has improved greatly due not only to an increase in the number of patients being referred for and undergoing surgical resection of their localised metastatic disease but also to a more strategic approach to the delivery of systemic therapy and an expansion in the use of ablative techniques. This reflects the increase in the number of patients that are being managed within a multidisciplinary team environment and specialist cancer centres, and the emergence over the same time period not only of improved imaging techniques but also prognostic and predictive molecular markers. Treatment decisions for patients with mCRC must be evidence-based. Thus, these ESMO consensus guidelines have been developed based on the current available evidence to provide a series of evidence-based recommendations to assist in the treatment and management of patients with mCRC in this rapidly evolving treatment setting.

BACKGROUND: Malaria, a disease caused by protozoan parasites of the genus Plasmodium and transmitted by female anopheline mosquitoes, is a major cause of morbidity, mortality and loss in productivity in humans. Baringo County is prone to seasonal transmissions of malaria mostly in the rainy seasons. METHODS: This cross-sectional study used a mixed methods approach to collect data on knowledge and lay management of malaria. A questionnaire survey was administered to 560 respondents while qualitative data was collected through 20 focus group discussions in four ecological zones covering Baringo North, Baringo South and Marigat sub-Counties of Baringo County. Analyses were done through summary and inferential statistics for quantitative data and content analysis for qualitative data. RESULTS: The study communities were knowledgeable of malaria signs, symptoms, cause and seasonality but this biomedical knowledge co-existed with other local perceptions. This knowledge, however, did not influence their first (p = 0.77) or second choice treatments (p = 0.49) and compliance to medication (p = 0.84). Up to 88 % of respondents reported having suffered from malaria. At the onset of a suspected malaria case community members reported the following: 28.9 % visited a health facility, 37.2 % used analgesics, 26.6 % herbal treatments, 2.2 % remnant malaria medicines, 2.2 % over the counter malaria medicines, 1 % traditional healers and 1.8 % other treatments. Nearly all respondents (97.8 %) reported visiting a health facility for subsequent treatments. Herbal treatments comprised of infusions and decoctions derived from roots, barks and leaves of plants believed to have medicinal value. Compliance to conventional malaria treatment regime was, however, identified as a challenge in malaria management. Quick relief from symptoms, undesirable qualities like drug bitterness and bad smell, undesirable side-effects, such as nausea and long regimen of treatment were some of the contributors to non-compliance. Men and women exhibited different health-seeking behaviours based on the cultural expectations of masculinity, femininity, gender roles and acceptability of health services. CONCLUSIONS: While knowledge of malaria is important in identifying the disease, it does not necessarily lead to good management practice. Treatment-seeking behaviour is also influenced by perceived cause, severity of disease, timing, anticipated cost of seeking treatment and gender, besides the availability of both traditional and conventional medicines.
RESUMO
Socialization tactics are often used to manage initial group member interactions in a way that facilitates transition experiences. Although this process is heavily researched in organizational contexts, we sought to extend this line of inquiry to sport by examining the nature of socialization tactics used to integrate new members into existing teams. Interviews were conducted with 12 coaches and 12 athletes from several Canadian Interuniversity Sport teams to explore the nature of socialization and the circumstances underscoring why certain approaches are taken over others. A key process involved establishing congruency of role expectations between incoming athletes and group leaders, and socialization processes balanced expectations of conformity with encouragement of individual personalities within the group. A conceptual basis to examine socialization into team sport environments is discussed in relation to the extant organizational theories, and the practical implications of delineating sport socialization tactics are forwarded.

BACKGROUND: Reports of positive effects of aerobic exercise on cognitive function in persons with Down syndrome are extremely limited. However, a novel exercise intervention, termed assisted cycling therapy (ACT), has resulted in acutely improved cognitive planning ability and reaction times as well as improved cognitive planning after 8 weeks of ACT in adolescents and young adults with Down syndrome. Here, we report the effects of 8 weeks of ACT on reaction time, set-shifting, inhibition and language fluency in adolescents with Down syndrome. METHODS: Adolescents with Down syndrome (age: ~18 years) were randomly assigned to 8 weeks of ACT (n = 17) or voluntary cycling (VC: n = 16), and a convenience sample (n = 11) was assigned to be an inactive comparison group (NC: n = 11). During ACT, the cycling cadence of the participants was augmented to an average cadence that was 80% faster than the voluntary cadence of the VC group. The increase in cadence was achieved with an electric motor in the stationary bicycle. Reaction time, set-shifting, inhibition and language fluency were assessed before and after 8 weeks of intervention. RESULTS: Power output and heart rates of the ACT and VC groups were almost identical, but the ACT cadence was significantly faster. The ACT group, but not the VC or NC groups, showed significantly improved reactions times (Hedges' g = -0.42) and inhibitory control (g = 0.18). Only the VC group showed improved set-shifting ability (g = 0.57). The ACT and VC groups displayed improved semantic language fluency (g = 0.25, g = 0.22, respectively). DISCUSSIONS: These and previous results support the hypothesis of increased neuroplasticity and prefrontal cortex function following ACT and, to a smaller extent, following VC. Both ACT and VC appear to be associated with cortical benefits, but based on current and previous results, ACT seems to maximize the benefits.

In childhood chronic illness, family communication can impact the child's and parents' psychosocial well-being. However, little is known about family communication in the context of epilepsy in childhood. The aim of this systematic review was to identify the existing evidence available on communication strategies adopted by families living with childhood epilepsy, including; the facilitators, barriers and challenges experienced by families when choosing to communicate, or not, about epilepsy; and the consequences of this communication. Papers published in the English language prior to March 2015 were identified following a search of six electronic databases: PubMed, MEDLINE, Web of Science, PsycINFO, CINAHL, and Scopus. Studies were included if they involved a sample of parents of children with epilepsy or children/young people with epilepsy (0-18years of age) and used qualitative, quantitative, or mixed methods. Following a comprehensive search and screening process, 26 studies were identified as eligible for inclusion in the review. No studies identified specific communication strategies adopted by families living with childhood epilepsy. Some studies found that talking about epilepsy with family members had positive consequences (e.g., communication as an effective coping strategy), with no negative consequences reported in any of the studies. The main barrier to communication for parents was an unwillingness to use the word "epilepsy" because of the perceived negative social connotations associated with the health condition. For children with epilepsy, barriers were as follows: parental desire to keep epilepsy a secret, parents' tendency to deny that the child had epilepsy, parental overprotection, and parents' tendency to impose greater restrictions on the child with epilepsy than on siblings without epilepsy. Future research investigating the communication strategies of families living with epilepsy is needed in order to create effective communication-based interventions for discussing epilepsy within the home.

Disclosing an epilepsy diagnosis to others is complex due to the condition's largely invisible nature and associated stigma. Despite this, little has been documented in terms of what this process involves for children living with epilepsy (CWE) and their parents. A systematic review was conducted to examine and synthesize evidence pertaining to: (i) the disclosure practices of CWE and their parents, (ii) enablers and barriers for disclosure, (iii) the impact of disclosure practices, and (iv) the relationship between disclosure management and other variables. The electronic databases PsycINFO, PubMed, MEDLINE, CINAHL, Scopus, and Web of Science were searched systematically. Any empirical, peer-reviewed journal articles with findings reported regarding the self- or proxy-reported disclosure practices of children aged 0-18years with any type of epilepsy and/or their parents were deemed eligible for inclusion. Two review authors completed all stages of screening, data extraction, and quality assessment independently with two additional review authors resolving any discrepancies. A total of 32 articles were included in the review. Only one dated study examined disclosure as a primary focus; in the remaining studies, disclosure was a subfocus of larger studies or pertinent qualitative themes/subthemes incidentally emerged. The limited evidence suggests that: 1) CWE and parents adopt varying disclosure management strategies - from concealment to voluntary disclosure; 2) disclosure decisions are challenging for CWE and parents; 3) many barriers to disclosure exist (e.g., fear of stigmatization and rejection); 4) only a limited number of factors that enable disclosure are known (e.g., openness by others to engage with and learn about epilepsy); 5) disclosure management is significantly related to a number of variables (e.g., child/maternal perceived stigma and seizure control); and 6) there are varying outcomes for CWE and/or their parents in accordance with the adoption of specific disclosure management strategies (e.g., disclosure resulting in greater acceptance and the receipt of support or evoking anxiety/fear in others; and concealment resulting in misunderstandings, embarrassment, and stigma-coaching), but the evidence remains inconclusive in terms of which disclosure management strategy is optimal. While some preliminary work has been conducted, disclosure of epilepsy is a topic that has been largely neglected to date. This is despite the fact that disclosure is a significant source of concern for CWE and parent populations. Future studies should focus on elucidating the unique contextual factors that inform disclosure decisions in order to develop a theoretical framework that can explain the epilepsy disclosure decision-making process.

Patient participation in cancer clinical trials is low. Little is known about attitudinal barriers to participation, particularly among patients who may be offered a trial during an imminent initial oncology consult. The aims of the present study were to confirm the presence of proposed subscales of a recently developed cancer clinical trial attitudinal barriers measure, describe the most common cancer clinical trials attitudinal barriers, and evaluate socio-demographic, medical and financial factors associated with attitudinal barriers. A total of 1256 patients completed a survey assessing demographic factors, perceived financial burden, prior trial participation and attitudinal barriers to clinical trials participation. Results of a factor analysis did not confirm the presence of the proposed four attitudinal barriers subscale/factors. Rather, a single factor represented the best fit to the data. The most highly-rated barriers were fear of side-effects, worry about health insurance and efficacy concerns. Results suggested that less educated patients, patients with non-metastatic disease, patients with no previous oncology clinical trial participation, and patients reporting greater perceived financial burden from cancer care were associated with higher barriers. These patients may need extra attention in terms of decisional support. Overall, patients with fewer personal resources (education, financial issues) report more attitudinal barriers and should be targeted for additional decisional support.

Background and Objective: Cancer is a leading cause of morbidity and mortality worldwide. The emergence of digital pathology and deep learning technologies signifies a transformative era in healthcare. These technologies can enhance cancer detection, streamline operations, and bolster patient care. A substantial gap exists between the development phase of deep learning models in controlled laboratory environments and their translations into clinical practice. This narrative review evaluates the current landscape of deep learning and digital pathology, analyzing the factors influencing model development and implementation into clinical practice. Methods: We searched multiple databases, including Web of Science, Arxiv, MedRxiv, BioRxiv, Embase, PubMed, DBLP, Google Scholar, IEEE Xplore, Semantic Scholar, and Cochrane, targeting articles on whole slide imaging and deep learning published from 2014 and 2023. Out of 776 articles identified based on inclusion criteria, we selected 36 papers for the analysis. Key Content and Findings: Most articles in this review focus on the in-laboratory phase of deep learning model development, a critical stage in the deep learning lifecycle. Challenges arise during model development and their integration into clinical practice. Notably, lab performance metrics may not always match real-world clinical outcomes. As technology advances and regulations evolve, we expect more clinical trials to bridge this performance gap and validate deep learning models' effectiveness in clinical care. High clinical accuracy is vital for informed decision-making throughout a patient's cancer care. Conclusions: Deep learning technology can enhance cancer detection, clinical workflows, and patient care. Challenges may arise during model development. The deep learning lifecycle involves data preprocessing, model development, and clinical implementation. Achieving health equity requires including diverse patient groups and eliminating bias during implementation. While model development is integral, most articles focus on the pre-deployment phase. Future longitudinal studies are crucial for validating models in real-world settings post-deployment. A collaborative approach among computational pathologists, technologists, industry, and healthcare providers is essential for driving adoption in clinical settings.
