Nodding Syndrome (NS) has occurred among severely food-stressed communities in northern Uganda and several other East African populations that, with their forced physical displacement, have resorted to nutritional support from available wild plants and fungi, some of which have neurotoxic potential. Among the latter is an agaric mushroom with an unknown content of hydrazine-generating agaritine, namely Agaricus bingensis, the unusually wide consumption of which may relate to the low serum levels of vitamin B6 in Ugandan NS subjects relative to controls. Hydrazine-related compounds induce patterns of DNA damage that promote neuropathological changes (tauopathy) reminiscent of those associated with established NS. While the cause of this childhood brain disease is unknown, we encourage increased attention to the role of malnutrition and B6 hypovitaminosis in the etiology of this devastating brain disease.

There seems to be no consensus among comparatists as to the meaning we should give to the expressions «mixed legal system» or «mixed jurisdictions» (they are frequently used interchangeably) but the issues at stake can be put into sharper focus. Unfortunately the classification schemes of mainstream comparative law afford almost no scope to the mixed systems and hardly venture into this subject. There are nevertheless two rival theories as to what these terms actually mean and how they should be applied. They give us different answers to the questions «What is a mixed jurisdiction and who is a mixed-jurisdiction jurist? On the one hand, scholars influenced by legal pluralism often entertain a wide conception of a mixed system. The sole requirement is the presence or interaction of two or more kinds of laws or legal traditions within a system. According to this viewpoint any interaction of laws of a different type or source - indigenous with exogenous, religious with customary - is sufficient to constitute a mixed legal system. This view revolutionizes the legal map offered by mainstream comparative law and leads to important insights that apply to European systems as well, but it has not yet succeeded in putting the resulting proliferation of mixed legal systems into any useful order for the purposes of comparative law. Other scholars on the other hand, particularly those inside classical mixed jurisdictions such as Scotland and Louisiana, have used a restricted and narrower notion of a mixed legal system. For the purposes of research or comparative law theory they have tended to limit this category to private-law systems based upon a core of common law and civil law elements, and other shared features stemming from this mixture. The paper traces the origins of this narrower approach and discusses the benefits of recent research comparing these kinds of jurisdictions. An attempt is made to reconcile the rival theories and to indicate that the classical mixed jurisdictions are a genus of the mixed species, and that the raison d'être of complex plural systems around the world with various «personal laws» is not that different than the reasons which led to the founding of the classical mixed systems. It is argued that comparative law research in the classic mixed systems is therefore strengthened by plurality consciousness and non-western elements in their legal order should not be ignored, for example in countries such as South Africa and Sri Lanka.

This article explores the concept of recovery and the role of vulnerability in suffering. It examines our overall discomfort with vulnerability in the context of narratives of violence, disorder, and the everyday. This discomfort is explored through a voyage of three narrative types: testimony, chaos, and restitution narratives (Frank, 1995). The article offers that while loss and narrative despair are the characteristic response of vulnerability storytelling does not always, contrary to dominant perspectives in narrative therapy and practice, result in narrative repair. Narrative despair--the pain, mourning, grief, and loss involved in telling stories--is central to a recovery of vulnerability [ABSTRACT FROM AUTHOR]

Let P be a submanifold properly immersed in a rotationally symmetric manifold having a pole and endowed with a weight e h. The aim of this paper is twofold. First, by assuming certain control on the h -mean curvature of P , we establish comparisons for the h -capacity of extrinsic balls in P , from which we deduce criteria ensuring the h -parabolicity or h -hyperbolicity of P. Second, we employ functions with geometric meaning to describe submanifolds of bounded h -mean curvature which are confined into some regions of the ambient manifold. As a consequence, we derive half-space and Bernstein-type theorems generalizing previous ones. Our results apply for some relevant h -minimal submanifolds appearing in the singularity theory of the mean curvature flow. [ABSTRACT FROM AUTHOR]

Abstract Background Intervention studies for depression and intimate partner violence (IPV) commonly incorporate screening to identify eligible participants. The challenge is that current ethical evaluation is largely informed by the four principle approach applying principles of beneficence, non-maleficence, and respect for justice and autonomy. We examine three intervention studies for IPV, postnatal depression (PND) and depression that used screening from the perspective of principlism, followed by the perspective of a narrative and relational approach. We suggest that a narrative and relational approach to ethics brings to light concerns that principlism can overlook. Discussion The justification most commonly used to incorporate screening is that the potential benefits of identifying intervention efficacy balance the risk of individual harm. However, considerable risks do exist. The discovery of new information may result in further depression or worries, people might feel burdened, open to further risk, unsure of whether to disclose information to family members and disappointed if they are allocated to a control group. This raises questions about study design and whether the principle of equipoise remains an adequate justification in studies with vulnerable groups. In addition, autonomy is said to be respected because participants give informed consent to participate. However, the context of where recruitment is undertaken has been shown to influence how people make decisions. Summary The four principles have been subjected to criticisms in recent years but they remain prominent in public health and medical research. We provide a set of simple, interrogative questions that are narrative and relationally driven which may assist to further evaluate the potential impacts of using screening to identify eligible research participants in intervention studies. A narrative and relational based approach requires seeing people as situated within their social and cultural contexts, and as existing within relationships that are likely to be affected by the results of screening information.

Abstract Background Depression and related disorders represent a significant part of general practitioners (GPs) daily work. Implementing the evidence about what works for depression care into routine practice presents a challenge for researchers and service designers. The emerging consensus is that the transfer of efficacious interventions into routine practice is strongly linked to how well the interventions are based upon theory and take into account the contextual factors of the setting into which they are to be transferred. We set out to develop a conceptual framework to guide change and the implementation of best practice depression care in the primary care setting. Methods We used a mixed method, observational approach to gather data about routine depression care in a range of primary care settings via: audit of electronic health records; observation of routine clinical care; and structured, facilitated whole of organisation meetings. Audit data were summarised using simple descriptive statistics. Observational data were collected using field notes. Organisational meetings were audio taped and transcribed. All the data sets were grouped, by organisation, and considered as a whole case. Normalisation Process Theory (NPT) was identified as an analytical theory to guide the conceptual framework development. Results Five privately owned primary care organisations (general practices) and one community health centre took part over the course of 18 months. We successfully developed a conceptual framework for implementing an effective model of depression care based on the four constructs of NPT: coherence, which proposes that depression work requires the conceptualisation of boundaries of who is depressed and who is not depressed and techniques for dealing with diffuseness; cognitive participation, which proposes that depression work requires engagement with a shared set of techniques that deal with depression as a health problem; collective action, which proposes that agreement is reached about how care is organised; and reflexive monitoring, which proposes that depression work requires agreement about how depression work will be monitored at the patient and practice level. We describe how these constructs can be used to guide the design and implementation of effective depression care in a way that can take account of contextual differences. Conclusions Ideas about what is required for an effective model and system of depression care in primary care need to be accompanied by theoretically informed frameworks that consider how these can be implemented. The conceptual framework we have presented can be used to guide organisational and system change to develop common language around each construct between policy makers, service users, professionals, and researchers. This shared understanding across groups is fundamental to the effective implementation of change in primary care for depression.

Abstract Background Social and structural inequities shape health and illness; they are an everyday presence within the doctor-patient encounter yet, there is limited ethical guidance on what individual physicians should do. This paper draws on a study that explored how doctors and their professional associations ought to respond to the issue of social health inequities. Results Some see doctors as bound by a notion of care that is blind to a patient's social position, while others respond to this issue through invoking notions of justice and human rights where access to care is a prime focus. Both care and justice orientations however conceal important tensions linked to the presence of bioethical principles underpinning these. Other normative ethical theories like deontology, virtue ethics and utilitarianism do not provide adequate guidance on the problem of social health inequities either. Conclusion This paper explores if Bauman's notion of "forms of togetherness" provides the basis of a relational ethical theory that can help to develop a response to social health inequities of relevance to individual physicians. This theory goes beyond silence on the influence of social position of health and avoids amoral regulatory approaches to monitoring equity of care provision.

Background The general practitioner's (GP) role in advance care planning is commonly tied to their knowledge of the patient and the family, but with limited attention to the nature of this knowing or the expectations it may give rise to (2012). GPs are often involved in advance care planning with the aim of having the patient complete formal documentation (2012). This paper proposes a broader role for the GP based on findings from a PhD study exploring older people's understandings of decision making in incompetence. Aim To explore patient's understanding of the GP's role in decision making in incompetence. Methods In-depth interviews with 19 people, aged ≥65 years, recruited from five general practices analysed using Giligan's (Gilligan et al., 2006) listening guide. Results Participants distinguished between their GP and other doctors. Participants described their relationship with their GP as grounds for providing the GP with a distinct role in the event of their future incompetence. Participants expected this relationship to inform the way their GP approached advance care planning. Discussion Participants expected the GP to have a richer role reflective than they are commonly provided. Relational ethics and the concept of 'generalism' provide a theoretical basis for expanding the GP's role. Conclusion Current characterisations of the GP's role overlook much of what they can bring to the process of advance care planning. [ABSTRACT FROM AUTHOR]

Background: Central centrifugal cicatricial alopecia (CCCA) is a primary lymphocytic scarring alopecia which occurs predominantly in Black middle-aged women.1,2 The benefits and prevalence of shared decision-making (SDM) models for CCCA patients have yet to be studied. Our study investigates the role of SDM in the management of CCCA., Methods: SDM processes were measured by the SDM-Q9, the Decisional Regret Scale (DRS), and the Patient Control Preferences Scale (CPS). Members of the Scarring Alopecia Foundation (n=1192) were recruited between June and August of 2023 via a one-time email sent via the Scarring Alopecia Foundation listserv., Results: 87 respondents were documented. The CPS (n=87) suggested that most patients (47.6% ; n=41) prefer to share responsibility with their doctor for treatment decisions. The SDM Q-9 (Scored 0-45) and DRS [scored 0-100] demonstrated mean scores of 27.5 (11.5) and 38.4 (19.4), with higher and lesser scores, respectively, demonstrating patient satisfaction with SDM., Discussion: SDM is useful in complex decision-making when there are several medically reasonable alternatives available for treatment. Patients with CCCA may benefit from this model, and investments in resources such as patient decision aids and SDM training for further dermatologists will aid integration into clinical practice., Limitation: There was no method of verifying the CCCA diagnosis for respondents. Additionally, most respondents had tertiary education, which limits generalizability to the wider population. Lastly, the low survey response rate (9.7%) predisposes to nonresponse bias., Conclusion: The CPS, SDM-Q-9, and DRS suggest that patients with CCCA prefer to be involved in management decisions., (© The Author(s) 2024.

Background: Frailty is a multi-dimensional syndrome associated with mortality and adverse outcomes in patients admitted to the intensive care unit (ICU). Further investigation is warranted to explore the interplay among factors such as frailty, clinical deterioration triggering a medical emergency team (MET) review, and outcomes following admission to the ICU., Methods: Single-centre, retrospective observational case-control study of adult patients (>18 years) admitted to a medical-surgical ICU with (cases) or without (controls) a preceding MET review between 4 h and 14 days prior. Matching was performed for age, ICU admission diagnosis, Acute Physiology and Chronic Health Evaluation III (APACHE III) score and the 8-point Clinical Frailty Scale (CFS). Cox proportional hazard regression modelling was performed to determine associations with 30-day mortality after admission to ICU., Results: A total of 2314 matched admissions were analysed. Compared to non-frail patients (CFS 1-4), mortality was higher in all frail patients (CFS 5-8), at 31% vs. 13%, and in frail patients admitted after MET review at 33%. After adjusting for age, APACHE, antecedent MET review and CFS in the Cox regression, mortality hazard ratio increased by 26% per CFS point and by 3% per APACHE III point, while a MET review was not an independent predictor. Limitations of medical treatment occurred in 30% of frail patients, either with or without a MET antecedent, and this was five times higher compared to non-frail patients., Conclusion: Frail patients admitted to ICU have a high short-term mortality. An antecedent MET event was associated with increased mortality but did not independently predict short-term survival when adjusting for confounding factors. The intrinsic significance of frailty should be primarily considered during MET review of frail patients. This study suggests that routine frailty assessment of hospitalised patients would be helpful to set goals of care when admission to ICU could be considered., (© 2024 The Acta Anaesthesiologica Scandinavica Foundation.

Background: Prevention and Recovery Care services are residential sub-acute services in Victoria, Australia, guided by a commitment to recovery-oriented practice. The evidence regarding the effectiveness of this service model is limited, largely relying on small, localised evaluations. This study involved a state-wide investigation into the personal recovery, perceived needs for care, well-being and quality-of-life outcomes experienced by Prevention and Recovery Care services' consumers., Methods: A longitudinal cohort design examined the trajectory of self-reported personal recovery and other outcomes for consumers in 19 Victorian Prevention and Recovery Care services over 4 time points (T1 - 1 week after admission; T2 - within 1 week of discharge; T3 - 6 months after discharge; T4 - 12 months after discharge). T2-T4 time frames were extended by approximately 3 weeks due to recruitment challenges. The Questionnaire about the Process of Recovery was the primary outcome measure., Results: At T1, 298 consumers were recruited. By T4, 114 remained in the study. Participants scored higher on the Questionnaire about the Process of Recovery at all three time points after T1. There were also sustained improvements on all secondary outcome measures. Improvements were then sustained at each subsequent post-intervention time point. Community inclusion and having needs for care met also improved., Conclusion: The findings provide a consistent picture of benefits for consumers using Prevention and Recovery Care services, with significant improvement in personal recovery, quality of life, mental health and well-being following an admission to a Prevention and Recovery Care service. Further attention needs to be given to how to sustain the gains made through a Prevention and Recovery Care service admission in the long term., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship and/or publication of this article.

Magnetic Resonance Imaging (MRI) is commonly used to follow the progression of neurodegenerative conditions, including multiple sclerosis (MS). MRI is limited by a lack of correlation between imaging results and clinical presentations, referred to as the clinico-radiological paradox. Animal models are commonly used to mimic the progression of human neurodegeneration and as a tool to help resolve the paradox. Most studies focus on later stages of white matter (WM) damage whereas few focus on early stages when oligodendrocyte apoptosis has just begun. The current project focused on these time points, namely weeks 2 and 3 of cuprizone (CPZ) administration, a toxin which induces pathophysiology similar to MS. In vivo T 2 -weighted (T 2 W) and Magnetization Transfer Ratio (MTR) maps and ex vivo Diffusion Tensor Imaging (DTI), Magnetization Transfer Imaging (MTI), and relaxometry (T 1 and T 2 ) values were obtained at 7 T. Significant changes in T 2 W signal intensity and non-significant changes in MTR were observed to correspond to early WM damage, whereas significant changes in both corresponded with full demyelination. Some DTI metrics decrease with simultaneous increase in others, indicating acute demyelination. MTI metrics T 2 A , T 2 B , f and R were observed to have contradictory changes across CPZ administration. T 1 relaxation times were observed to have stronger correlations to disease states during later stages of CPZ treatment, whereas T 2 had weak correlations to early WM damage. These results all suggest the need for multiple metrics and further studies at early and late time points of demyelination. Further research is required to continue investigating the interplay between various MR metrics during all weeks of CPZ administration.

Psoriasis is strongly associated with cardiovascular disease (CVD) and metabolic syndrome, with patients having an approximately twofold increased risk of each compared to the general population. This increased risk is based on shared underlying genetic and cytokine profiles, as well as similar environmental risks. Many screening guidelines do not address the development of CVD and metabolic syndrome in these predisposed patients. These deficits are evidenced by the exclusion of psoriasis as a risk factor in validated 10-year CVD risk calculators for adult patients with chronic inflammatory diseases, as well as insufficient screening guidelines for insulin resistance in patients with psoriasis. This manuscript aims to discuss and propose allopathic and lifestyle recommendations for the screening and management of the aforementioned comorbidities in adult patients with psoriasis., (© 2023 the International Society of Dermatology.)

Optimal sleep, both in terms of duration and quality, is important for adolescent health. However, young people's sleeping habits have worsened over recent years. Access to and use of interactive electronic devices (e.g., smartphones, tablets, portable gaming devices) and social media have become deep-rooted elements of adolescents' lives and are associated with poor sleep. Additionally, there is evidence of increases in poor mental health and well-being disorders in adolescents; further linked to poor sleep. This review aimed to summarise the longitudinal and experimental evidence of the impact of device use on adolescents' sleep and subsequent mental health. Nine electronic bibliographical databases were searched for this narrative systematic review in October 2022. Of 5779 identified unique records, 28 studies were selected for inclusion. A total of 26 studies examined the direct link between device use and sleep outcomes, and four reported the indirect link between device use and mental health, with sleep as a mediator. The methodological quality of the studies was generally poor. Results demonstrated that adverse implications of device use (i.e., overuse, problematic use, telepressure, and cyber-victimisation) impacted sleep quality and duration; however, relationships with other types of device use were unclear. A small but consistent body of evidence showed sleep mediates the relationship between device use and mental health and well-being in adolescents. Increasing our understanding of the complexities of device use, sleep, and mental health in adolescents are important contributions to the development of future interventions and guidelines to prevent or increase resilience to cyber-bullying and ensure adequate sleep., (© 2023 The Authors.

Central centrifugal cicatricial alopecia (CCCA) is a lymphocytic scarring alopecia that predominantly affects women of African descent. Recent studies have demonstrated prevalence in children and adolescents, as well as Asian populations. A thorough search of Pubmed, Cochrane Database of Systematic Reviews, OVID Medline and Google Scholar was conducted using keywords such as "central centrifugal cicatricial alopecia", "scarring hair loss", "scarring alopecia", "hot comb alopecia", "pediatric" and "adolescent". The results yielded few articles in the literature that directly addressed CCCA in the adolescent population, with three articles providing details of the presentation in the form of case series and retrospective reviews. The presentation in the adolescent population was found to be varied, ranging from asymptomatic to symptomatic and involving diffuse to patchy hair loss in only the vertex and/or frontal and parietal scalp. Genetic and environmental etiologies were found to be statistically significant, and markers of metabolic dysregulation predisposing patients to diabetes mellitus and breast cancer were also uncovered. The differential diagnosis of patients who present with hair loss in the adolescent population should therefore be broad, and a low threshold for biopsies should be adopted to confirm CCCA in suspected patients. This will have future implications for reduced morbidity and public health.

Background: A randomised trial of European Fans in Training (EuroFIT), a 12-week healthy lifestyle program delivered in 15 professional football clubs in the Netherlands, Norway, Portugal, and the United Kingdom, successfully increased physical activity and improved diet but did not reduce sedentary time. To guide future implementation, this paper investigates how those effects were achieved. We ask: 1) how was EuroFIT implemented? 2) what were the processes through which outcomes were achieved?, Methods: We analysed qualitative data implementation notes, observations of 29 of 180 weekly EuroFIT deliveries, semi-structured interviews with 16 coaches and 15 club representatives, and 30 focus group discussions with participants (15 post-program and 15 after 12 months). We descriptively analysed quantitative data on recruitment, attendance at sessions and logs of use of the technologies and survey data on the views of participants at baseline, post program and after 12 months. We used a triangulation protocol to investigate agreement between data from difference sources, organised around meeting 15 objectives within the two research questions., Results: We successfully recruited clubs, coaches and men to EuroFIT though the draw of the football club seemed stronger in the UK and Portugal. Advertising that emphasized getting fitter, club-based deliveries, and not 'standing out' worked and attendance and fidelity were good, so that coaches in all countries were able to deliver EuroFIT flexibly as intended. Coaches in all 15 clubs facilitated the use of behaviour change techniques and interaction between men, which together enhanced motivation. Participants found it harder to change sedentary time than physical activity and diet. Fitting changes into daily routines, planning for setbacks and recognising the personal benefit of behaviour change were important to maintain changes. Bespoke technologies were valued, but technological hitches frustrated participants., Conclusion: EuroFIT was delivered as planned by trained club coaches working flexibly in all countries. It worked as expected to attract men and support initiation and maintenance of changes in physical activity and diet but the use of bespoke, unstable, technologies was frustrating. Future deliveries should eliminate the focus on sedentary time and should use only proven technologies to support self-monitoring and social interaction., Trial Registration: ISRCTN81935608, registered 16/06/2015., (© 2023.

There has been increasing adoption and implementation of virtual healthcare in recent years, especially with COVID-19 impacting the world. As a result, virtual care initiatives may not undergo stringent quality control processes to ensure that they are appropriate to their context and meet sector needs. The two objectives of this study were to identify virtual care initiatives for older adults currently in use in Victoria and virtual care challenges that could be prioritised for further investigation and scale-up and to understand why certain virtual care initiatives and challenges are prioritised over others for investigation and scale-up., Methods: This project used an Emerging Design approach. A survey of public health services in the state of Victoria in Australia was first carried out, followed by the co-production of research and healthcare priorities with key stakeholders in the areas of primary care, hospital care, consumer representation, research, and government. The survey was used to gather existing virtual care initiatives for older adults and any associated challenges. Co-production processes consisted of individual ratings of initiatives and group-based discussions to identify priority virtual care initiatives and challenges to be addressed for future scale-up. Stakeholders nominated their top three virtual initiatives following discussions., Results: Telehealth was nominated as the highest priority initiative type for scaling up, with virtual emergency department models of care nominated as the highest priority within this category. Remote monitoring was voted as a top priority for further investigations. The top virtual care challenge was data sharing across services and settings, and the user-friendliness of virtual care platforms was nominated as the top priority for further investigation., Conclusions: Stakeholders prioritised public health virtual care initiatives that are easy to adopt and address needs that are perceived to be more immediate (acute more so than chronic care). Virtual care initiatives that incorporate more technology and integrated elements are valued, but more information is needed to inform their potential scale-up.

WHAT IS KNOWN ON THE SUBJECT?: Little is known about adolescent inpatient units, key features which define them, and how these essential services operate and deliver care. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE?: Adolescent inpatient unit studies are limited in their descriptions of settings in terms of how they operate and key features. The proposed preliminary checklist is a practical tool to assist clinicians, policy makers, and researchers when reporting to ensure comprehensive descriptions of adolescent inpatient settings. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: This could be used to inform service design processes for inpatient and other mental health service models which is of critical importance in the context of reforms and implementation of these in Australia currently. Greater attention to operational models, services, and philosophies of practice will improve reporting and allow for the advancement of knowledge, comparison of study results, and a clearer direction for mental health nursing clinicians and researchers. ABSTRACT: Introduction Adolescent inpatient units care for vulnerable population groups; however, little is known about how these essential services operate and deliver care. Aims To examine the descriptions of adolescent mental health inpatient units in Australian and international research publications and to identify key features which were used to define them. A secondary aim was to develop a checklist to improve consistency when reporting on the operations and services delivered within adolescent mental health inpatient units (both public and private). Methods Five electronic databases (CINAHL, MEDLINE, ERIC, EMBASE, and PsycINFO) were systematically searched. We included studies that provided descriptions of operations and services within adolescent inpatient units where participants had a mean age between 12 and 25. Narrative synthesis was used to explore the similarities and differences between descriptions of settings. Results Twenty-eight studies were identified, which varied in their descriptions of adolescent inpatient units, providing inconsistent information to inform best practice. Discussion Studies lack consistency and comprehensive detail when describing the operational models within inpatient units, making interpretation challenging. Consequently, a preliminary checklist is proposed to improve reporting of adolescent inpatient units., (© 2022 The Authors.

Background: Burnout is a work-related syndrome documented to have negative consequences for GPs and their patients., Aim: To review the existing literature concerning studies published up to December 2020 on the prevalence of burnout among GPs in general practice, and to determine GP burnout estimates worldwide., Design and Setting: Systematic literature search and meta-analysis., Method: Searches of CINAHL Plus, Embase, MEDLINE, PsycINFO, and Scopus were conducted to identify published peer-reviewed quantitative empirical studies in English up to December 2020 that have used the Maslach Burnout Inventory - Human Services Survey to establish the prevalence of burnout in practising GPs (that is, excluding GPs in training). A random-effects model was employed., Results: Wide-ranging prevalence estimates (6% to 33%) across different dimensions of burnout were reported for 22 177 GPs across 29 countries were reported for 60 studies included in this review. Mean burnout estimates were: 16.43 for emotional exhaustion; 6.74 for depersonalisation; and 29.28 for personal accomplishment. Subgroup and meta-analyses documented that country-specific factors may be important determinants of the variation in GP burnout estimates. Moderate overall burnout cut-offs were found to be determinants of the variation in moderate overall burnout estimates., Conclusion: Moderate to high GP burnout exists worldwide. However, substantial variations in how burnout is characterised and operationalised has resulted in considerable heterogeneity in GP burnout prevalence estimates. This highlights the challenge of developing a uniform approach, and the importance of considering GPs' work context to better characterise burnout., (© The Authors.)

Nodding Syndrome (NS) has occurred among severely food-stressed communities in northern Uganda and several other East African populations that, with their forced physical displacement, have resorted to nutritional support from available wild plants and fungi, some of which have neurotoxic potential. Among the latter is an agaric mushroom with an unknown content of hydrazine-generating agaritine, namely Agaricus bingensis , the unusually wide consumption of which may relate to the low serum levels of vitamin B6 in Ugandan NS subjects relative to controls. Hydrazine-related compounds induce patterns of DNA damage that promote neuropathological changes (tauopathy) reminiscent of those associated with established NS. While the cause of this childhood brain disease is unknown, we encourage increased attention to the role of malnutrition and B6 hypovitaminosis in the etiology of this devastating brain disease., Competing Interests: The authors declare no competing interests., (© 2022 Published by Elsevier B.V.)

There is a push for greater promotion of dementia risk reduction (DRR) by primary care practitioners (PCPs). The aims of this study were to understand the views of non-medically trained Australian contributors in a Massive Open Online Course (MOOC) about dementia prevention regarding the role of PCPs in promoting DRR and to consider the implications of those views for developing implementation strategies. Discussion board posts of MOOC enrollees were analysed regarding the actions that organisations, communities and/or governments should take to help people work towards DRR. Of the 1641 eligible contributors to the discussion, 160 (10%) indicated that PCPs had a role in promoting DRR. This subset of participants particularly wanted earlier identification of risk by PCPs and a discussion about DRR. Some participants thought PCPs did not currently prioritise DRR, lacked knowledge about DRR and faced Medicare and resource restrictions to promoting DRR. We suggest that PCPs need: better publicity for their role in promoting DRR; to prioritise DRR; knowledge about DRR; and to take advantage of existing opportunities to promote DRR quickly. The findings of this study should be considered when attempting to implement DRR guidelines in primary care.

This case-control study adds to the growing body of knowledge on the medical, nutritional, and environmental factors associated with Nodding Syndrome (NS), a seizure disorder of children and adolescents in northern Uganda. Past research described a significant association between NS and prior history of measles infection, dependence on emergency food and, at head nodding onset, subsistence on moldy maize, which has the potential to harbor mycotoxins. We used LC-MS/MS to screen for current mycotoxin loads by evaluating nine analytes in urine samples from age-and-gender matched NS cases (n = 50) and Community Controls (CC, n = 50). The presence of the three mycotoxins identified in the screening was not significantly different between the two groups, so samples were combined to generate an overall view of exposure in this community during the study. Compared against subsequently run standards, α-zearalenol (43 ± 103 µg/L in 15 samples > limit of quantitation (LOQ); 0 (0/359) µg/L), T-2 toxin (39 ± 81 µg/L in 72 samples > LOQ; 0 (0/425) µg/L) and aflatoxin M1 (4 ± 10 µg/L in 15 samples > LOQ; 0 (0/45) µg/L) were detected and calculated as the average concentration ± SD; median (min/max). Ninety-five percent of the samples had at least one urinary mycotoxin; 87% were positive for two of the three compounds detected. While mycotoxin loads at NS onset years ago are and will remain unknown, this study showed that children with and without NS currently harbor foodborne mycotoxins, including those associated with maize.

Purpose: To characterize surgical confusions in ophthalmology to determine their incidence, root causes, and impact on patients and physicians., Design: Retrospective cohort study of errors in ophthalmic surgical procedures between January 1, 2006, and December 31, 2017., Participants: One hundred forty-three cases involving surgical confusions., Methods: Cases were identified by the Ophthalmic Mutual Insurance Company from closed case files and by the New York State Health Department from the New York Patient Occurrence Reporting and Tracking program that identified the surgical confusions., Main Outcome Measures: Incidence and impact by intended surgery, error type, and root cause as well as preventability by the Universal Protocol., Results: Of the 143 cases of surgical confusions identified, 92 cases (64.3%) were deemed preventable by the Universal Protocol. Approximately two thirds, 95 cases (66.4%), were cases of incorrect implants being used during cataract surgery (cataract extraction and intraocular lens implantation), of which 33 cases (34.7%) were not preventable by the Universal Protocol. Wrong eye blocks or anesthesia accounted for 20 cases (14.0%), incorrect eye procedures accounted for 10 cases (7.00%), incorrect refractive surgery measurements accounted for 6 cases (4.20%), incorrect patient or procedure accounted for 5 cases (3.50%), incorrect intraocular gas concentration accounted for 4 cases (2.80%), and incorrect medication in surgery accounted for 3 cases (2.10%). The most common root cause of confusion was an inadequately performed time out, which was responsible for nearly one third of all surgical confusions, 46 cases (32.2%). Incorrect lens orders or calculations before surgery (so-called upstream errors) were the second most common cause of surgical confusion, involving 31 cases (21.7%). The average legal indemnity for incorrect implant during cataract surgery was $57 514 (United States dollars). The average indemnity for incorrect refractive surgery measurement was $123 125, that for incorrect eye procedure was $50 000, and that for incorrect gas concentration was $220 844., Conclusions: Most surgical confusions could have been prevented by following the Universal Protocol properly. However, upstream errors, originating in the clinic or office before surgery, and ineffective communication during time outs suggest a need for modification of the Universal Protocol., (Copyright © 2019 American Academy of Ophthalmology.

The consumption by humans of plants with potential to induce neurological disorders is widespread, but overt disease surfaces only when the subject's toxic threshold is exceeded. Excessive intake arising from food dependency in the setting of hunger, chronic undernutrition, vitamin deficiency, inadequate detoxication, or other individual susceptibility, can trigger acute encephalopathy (lychee, ackee fruits), sub-acute spastic paraparesis (grasspea, cassava root/leaves) or ataxic neuropathy (cassava root flour). While these disorders are very rarely encountered in high-income countries, they are not only common among impoverished populations but also often occur as outbreaks that impact a significant proportion of an affected community. Unfamiliarity with the adverse effects of plant toxins has sometimes led to the mistaken attribution of nutritional neurotoxic disease to a neurotropic viral or synthetic pesticidal etiology. The combination of human population growth, food and water insecurity, poverty and, with climate change, increased dependency on environmentally tolerant plants with neurotoxic potential, predictably may result in an increased prevalence of nutritional neurotoxic disorders, especially in certain parts of Africa and Asia., (Copyright © 2019 Elsevier Masson SAS.

The human environment and exposures arising therefrom are major contributors to neurological disorders ranging from stroke to neurodegenerative diseases. Reduction of exposure to environmental risk factors, with the goal of disease prevention or control, is addressed at the individual as well as the societal level and in recognition of differential subject vulnerability. We examine some practical solutions in high-income countries that may allow a better adaptation to environmental risks and reduce their adverse impact on the nervous system. We consider the citizen's role in reducing unhealthy exposures and explore new approaches to treatment., (Copyright © 2019 Elsevier Masson SAS. All rights reserved.)

Nodding syndrome (NS) is a progressive encephalopathy of children and adolescents characterized by seizures, including periodic vertical head nodding. Epidemic NS, which has affected parts of East Africa, appears to have clinical overlap with sub-Saharan Nakalanga syndrome (NLS), a brain disorder associated with pituitary dwarfism that appears to have a patchy distribution across sub-Sahara. Clinical stages of NS include inattention and blank stares, vertical head nodding, convulsive seizures, multiple impairments, and severe cognitive and motorsystem disability, including features suggesting parkinsonism. Head nodding episodes occur in clusters with an electrographic correlate of diffuse high-amplitude slow waves followed by an electrodecremental pattern with superimposed diffuse fast activity. Brain imaging reveals differing degrees of cerebral cortical and cerebellar atrophy. Brains of NS-affected children with mild frontotemporal cortical atrophy display neurofibrillary pathology and dystrophic neurites immunopositive for tau, consistent with a progressive neurodegenerative disorder. The etiology of NS and NLS appears to be dominated by environmental factors, including malnutrition, displacement, and nematode infection, but the specific cause is unknown., (Copyright © 2019 The Authors.
