People with type 2 diabetes (T2D) are more likely to experience binge eating than the general population, which may interfere with their diabetes management. Guided self-help (GSH) is one of the recommended treatment options for binge eating disorder, but there is currently a lack of evidenced treatment for binge eating in individuals living with T2D. The aims of this pilot study were to test the feasibility and acceptability of recruiting and delivering the adapted, online Working to Overcome Eating Difficulties GSH intervention to adults with T2D and binge eating. The intervention comprises GSH materials presented online in seven sections delivered over 12 weeks, supported by a trained Guide. Twenty-two participants were recruited in a case series design to receive the intervention and we interviewed four Guides and five participants afterwards. We measured binge eating, mental wellbeing, quality of life and weight at pre-post and 12-week follow-up. Results showed a significant reduction in binge eating at the end of the intervention, which continued to improve at follow-up. Before the programme, 92 % of participants scored above cut-off for binge eating. This reduced to 41 % post-intervention and no-one at follow-up. These changes were accompanied by significant improvements in depression, anxiety and small changes in eating disorder symptoms. Participants reported making better lifestyle choices, eating more mindfully and having increased self-confidence. The study shows preliminary evidence for online GSH tailored to the needs of individuals with T2D as a feasible and acceptable approach to improving binge eating, diabetes management and mental wellbeing.
Diagnosis of acute ischemia typically relies on evidence of ischemic lesions on magnetic resonance imaging (MRI), a limited diagnostic resource. We aimed to determine associations of clinical variables and acute infarcts on MRI in patients with suspected low-risk transient ischemic attack (TIA) and minor stroke and to assess their predictive ability.
Methods:
We conducted a post-hoc analysis of the Diagnosis of Uncertain-Origin Benign Transient Neurological Symptoms (DOUBT) study, a prospective, multicenter cohort study investigating the frequency of acute infarcts in patients with low-risk neurological symptoms. Primary outcome parameter was defined as diffusion-weighted imaging (DWI)-positive lesions on MRI. Logistic regression analysis was performed to evaluate associations of clinical characteristics with MRI-DWI-positivity. Model performance was evaluated by Harrel’s c-statistic.
Results:
In 1028 patients, age (Odds Ratio (OR) 1.03, 95% Confidence Interval (CI) 1.01–1.05), motor (OR 2.18, 95%CI 1.27–3.65) or speech symptoms (OR 2.53, 95%CI 1.28–4.80), and no previous identical event (OR 1.75, 95%CI 1.07–2.99) were positively associated with MRI-DWI-positivity. Female sex (OR 0.47, 95%CI 0.32–0.68), dizziness and gait instability (OR 0.34, 95%CI 0.14–0.69), normal exam (OR 0.55, 95%CI 0.35–0.85) and resolved symptoms (OR 0.49, 95%CI 0.30–0.78) were negatively associated. Symptom duration and any additional symptoms/symptom combinations were not associated. Predictive ability of the model was moderate (c-statistic 0.72, 95%CI 0.69–0.77).
Conclusion:
Detailed clinical information is helpful in assessing the risk of ischemia in patients with low-risk neurological events, but a predictive model had only moderate discriminative ability. Patients with clinically suspected low-risk TIA or minor stroke require MRI to confirm the diagnosis of cerebral ischemia.
Multiple studies have demonstrated that European colonization of the Americas led to the death of nearly all North American dog mitochondrial lineages and replacement with European ones sometime between AD 1492 and the present day. Historical records indicate that colonists imported dogs from Europe to North America, where they became objects of interest and exchange as early as the seventeenth century. However, it is not clear whether the earliest archaeological dogs recovered from colonial contexts were of European, Indigenous, or mixed descent. To clarify the ancestry of dogs from the Jamestown Colony, Virginia, we sequenced ancient mitochondrial DNA from six archaeological dogs from the period 1609–1617. Our analysis shows that the Jamestown dogs have maternal lineages most closely associated with those of ancient Indigenous dogs of North America. Furthermore, these maternal lineages cluster with dogs from Late Woodland, Hopewell, and Virginia Algonquian archaeological sites. Our recovery of Indigenous dog lineages from a European colonial site suggests a complex social history of dogs at the interface of Indigenous and European populations during the early colonial period.
We investigated the impact of workflow times on the outcomes of patients treated with endovascular thrombectomy (EVT) in the late time window.
Methods:
Individual patients’ data who underwent EVT in the late time window (onset to imaging >6 hours) were pooled from seven registries and randomized clinical trials. Multiple time intervals were analyzed. Mixed-effects logistic regression was used to estimate the likelihood of functional independence at 90 days (modified Rankin Scale 0–2). Mixed-effects negative binomial regression was used to evaluate the relationship between patient characteristics and workflow time intervals.
Results:
608 patients were included. The median age was 70 years (IQR: 58–71), 307 (50.5%) were female, and 310 (53.2%) had wake-up strokes. Successful reperfusion was achieved in 493 (81.2%) patients, and 262 (44.9%) achieved 90-day mRS 0–2. The estimated odds of functional independence decreased by 13% for every 30 minute delay from emergency department (ED) arrival to imaging time and by 7% from ED arrival to the end of EVT in the entire cohort. Also, the estimated odds of functional independence decreased by 33% for every 30 minute delay in the interval from arterial puncture to end of EVT, 16% in the interval from arrival in ED to end of EVT and 6% in the interval from stroke onset to end of EVT among patients who had a wake-up stroke.
Conclusion:
Faster workflow from ED arrival to end of EVT is associated with improved functional independence among stroke patients treated in the late window.
Central nervous system (CNS) infections with the dematiaceous fungus Cladophialophora bantiana (C. bantiana) are extremely rare, with approximately 120 confirmed cases reported as of 2016. C. bantiana is a highly neurotropic and thermotolerant fungus found in soil worldwide. The mode of entry into the CNS remains unknown, but inhalation of fungal spores or subcutaneous trauma have been suggested. Entry of fungal spores can cause cerebral phaeohyphomycosis with the main clinical manifestation of a brain abscess. Symptoms are non-specific and can include headache, fever, hemiparesis, aphasia, visual disturbances, and confusion. C. bantiana cerebral phaeohyphomycosis occurs in both immunocompetent and immunocompromised individuals, with a slightly higher prevalence in immunocompetent males for unknown reasons. Diagnosis is often delayed due to its nonspecific presentation and prevalence in individuals without pre-existing immunological disease. Prognosis is poor, with mortality rates of approximately 70% despite aggressive treatment. Treatment is not standardized but may include several anti-fungal agents and surgical intervention. Case reports documenting the variability seen with cerebral phaeohyphomycosis by C. bantiana can provide valuable insight into this emerging disease. C. bantiana’s neurotropic propensity also warrants cognitive investigation of the disease; however, there are currently limited descriptions of cognitive findings in published case reports of C. bantiana CNS infections.
Participants and Methods:
Here, we describe a case of a 35-year-old immunocompetent, college educated male with a CNS C. bantiana infection, presumably following a fall while biking in Costa Rica. First symptoms included left sided facial palsy, headache, and hand weakness, prompting extensive diagnostic workup, with diagnosis of C. bantiana infection confirmed 8 months after symptom onset. Initial treatment included anti-fungal agents and steroids, but his course of infection was complicated by infectious vasculitis with posterior circulation infarcts and obstructive hydrocephalus requiring ventriculoperitoneal shunt placement two years following the fungal infection diagnosis. The most recent brain MRI revealed encephalomalacia in global periventricular areas, two small masses, likely representing small fungal phlegmons, and enhancing lesions in the upper cervical spinal canal.
Results:
The patient reported cognitive changes following the infarcts and shunt placement including difficulties with spatial navigation, following directions, and articulating thoughts. Memory concerns and lapses in judgment were also reported. Results from a neuropsychological evaluation revealed high average baseline intellectual abilities with decrements in visuospatial processing, processing speed, executive functioning, and aspects of memory stemming from his executive dysfunction. At the time, his cognitive profile suggested parietal and frontosubcortical systems disruption meeting criteria for mild cognitive impairment. Two years later, the patient reported continuing cognitive difficulties prompting a follow-up neuropsychological evaluation. Results were similar to his first evaluation, revealing deficits in aspects of visuospatial processing, decreased verbal and visual learning, bradyphrenia and processing speed deficits, and difficulties with visual planning and organization. Minimal anxiety and depression, but increased apathy and executive dysfunction were endorsed on self-report measures.
Conclusions:
This case report highlights neurological sequela resulting from CNS infection with C. bantiana, -with a course complicated by subsequent strokes, hydrocephalus, and cognitive impairment-, and contributes additional insight into the relatively limited existing reports of an extremely rare but emerging disease.
The cornerstone of obesity treatment is behavioural weight management, resulting in significant improvements in cardio-metabolic and psychosocial health. However, there is ongoing concern that dietary interventions used for weight management may precipitate the development of eating disorders. Systematic reviews demonstrate that, while for most participants medically supervised obesity treatment improves risk scores related to eating disorders, a subset of people who undergo obesity treatment may have poor outcomes for eating disorders. This review summarises the background and rationale for the formation of the Eating Disorders In weight-related Therapy (EDIT) Collaboration. The EDIT Collaboration will explore the complex risk factor interactions that precede changes to eating disorder risk following weight management. In this review, we also outline the programme of work and design of studies for the EDIT Collaboration, including expected knowledge gains. The EDIT studies explore risk factors and the interactions between them using individual-level data from international weight management trials. Combining all available data on eating disorder risk from weight management trials will allow sufficient sample size to interrogate our hypothesis: that individuals undertaking weight management interventions will vary in their eating disorder risk profile, on the basis of personal characteristics and intervention strategies available to them. The collaboration includes the integration of health consumers in project development and translation. An important knowledge gain from this project is a comprehensive understanding of the impact of weight management interventions on eating disorder risk.
Hercules Dome, Antarctica, has long been identified as a prospective deep ice core site due to the undisturbed internal layering, climatic setting and potential to obtain proxy records from the Last Interglacial (LIG) period when the West Antarctic ice sheet may have collapsed. We performed a geophysical survey using multiple ice-penetrating radar systems to identify potential locations for a deep ice core at Hercules Dome. The surface topography, as revealed with recent satellite observations, is more complex than previously recognized. The most prominent dome, which we term ‘West Dome’, is the most promising region for a deep ice core for the following reasons: (1) bed-conformal radar reflections indicate minimal layer disturbance and extend to within tens of meters of the ice bottom; (2) the bed is likely frozen, as evidenced by both the shape of the measured vertical ice velocity profiles beneath the divide and modeled ice temperature using three remotely sensed estimates of geothermal flux and (3) models of layer thinning have 132 ka old ice at 45–90 m above the bed with an annual layer thickness of ~1 mm, satisfying the resolution and preservation needed for detailed analysis of the LIG period.
The Tugen Hills range in Central Kenya is a 75 km north–south-oriented horst block tilted to the west (Chapman, 1971; Chapman et al., 1978; Hill et al., 1986; Williams and Chapman, 1986). The range is situated to the west of Lake Baringo and forms the eastern margin of the Kerio Valley (Figure 27.1).
Rehabilitation therapy is a key part of the recovery pathway for people with severe acquired brain injury (ABI). The aim of this study was to explore inpatients’ and their family members’ experiences of a specialist ABI rehabilitation service.
Methods:
A cross sectional, prospective mixed method study was undertaken at a metropolitan specialist ABI rehabilitation unit in Victoria, Australia. All inpatients and their family members of the service were invited to complete a satisfaction survey. Employing purposive sampling, semi-structured interviews were conducted with inpatients and/or their family members.
Results:
In total, 111 people completed the satisfaction survey and 13 were interviewed. High levels of satisfaction with the specialist service were reported; the majority of inpatients (74%) and family members (81%) rated the overall quality of care received in the service as ‘high’ or ‘very high’. Interviews revealed four main themes: (i) satisfaction with rehabilitation services, (ii) inconsistent communication, (iii) variable nursing care, and (iv) strengths and weakness of the rehabilitation environment. Overall, important components of a positive experience were being involved in decision making and discharge planning, effective communication and information processes, and being able to form therapeutic relationships with staff. Key sources of dissatisfaction for inpatients and family members related to inconsistency in care, accessing information about treatments in a format easily understood, and communication.
Conclusion:
Specialised rehabilitation is valued by inpatients and their family members alike. The findings highlight the importance of exploring inpatient experiences to optimise service delivery in a tailored, specialised rehabilitation programme.
This paper provides a large-scale, per Major League Baseball (MLB) game analysis of foul ball (FB) injury data and provides estimates of injury frequency and severity.
Objective:
This study’s goal was to quantify and describe the rate and type of FB injuries at MLB games.
Design:
This was a retrospective review of medical care reports for patients evaluated by on-site health care providers (HCPs) over a non-contiguous 11-year period (2005-2016). Data were obtained using Freedom of Information Act (FOIA) requests.
Setting:
Data were received from three US-based MLB stadiums.
Results:
The review reported 0.42-0.55 FB injuries per game that were serious enough to warrant presentation at a first aid center. This translated to a patients per 10,000 fans rate (PPTT) of 0.13-0.23. The transport to hospital rate (TTHR) was 0.02-0.39. Frequently, FB injuries required analgesics but were overwhelmingly minor and occurred less often than non-FB traumatic injuries (5.2% versus 42%-49%). However, FB injured fans were more likely to need higher levels of care and transport to hospital (TH) as compared to people suffering other traumatic injuries at the ballpark. Contusions or head injuries were common. Finally, FB injured fans were often hit in the abdomen, upper extremity, face, or head. It was found that FB injuries appeared to increase with time, and this increase in injuries aligns with the sudden increase in popularity of smartphones in the United States.
Conclusions and Relevance:
These data suggest that in roughly every two or three MLB games, a foul ball causes a serious enough injury that a fan seeks medical attention. This rate is high enough to warrant attention, but is comparable in frequency to other diagnostic categories. Assessing the risk to fans from FBs remains difficult, but with access to uniform data, researchers could answer persistent questions that would lead to actionable changes and help guide public policy towards safer stadiums.
Artificial intelligence (AI) shares many generalizability challenges with psychology. But the fields publish differently. AI publishes fast, through rapid preprint sharing and conference publications. Psychology publishes more slowly, but creates integrative reviews and meta-analyses. We discuss the complementary advantages of each strategy, and suggest that incorporating both types of strategies could lead to more generalizable research in both fields.
The Scottish Medicines Consortium (SMC) conducts early health technology assessment (HTA) of new medicines. The advice is implemented at the local level by 14 Health Board Area Drug and Therapeutics Committees (ADTCs). The primary output is a published document, the Detailed Advice Document (DAD), which aims to describe the strengths and weaknesses of the evidence considered and the rationale for the decision. We examined how the DAD is being used to determine areas for improvement.
Methods
We conducted semi-structured interviews with a purposive sample of SMC and ADTC members and formulary pharmacists, who are one of the key audiences. Interviews were recorded and transcribed using Microsoft Teams and coded in NVivo. The results were assessed via thematic analysis, which included major themes such as the structure and content of the DAD and its usefulness in supporting implementation of the advice from an ADTC perspective.
Results
Following initial interviews (n = 7), some early themes have emerged. The DAD is a valued tool describing the assessment of a medicine's clinical and cost effectiveness. The current length of the DADs and the technical language used can limit the accessibility of information, and there have been suggestions on how to improve the structure and content. Additional interviews are still being completed and full interview results (available early 2021) will be analyzed to identify key themes.
Conclusions
The DAD is the primary output of SMC's HTA process, which includes decisions on whether a medicine can be routinely prescribed in the National Health Service Scotland. DADs have increased in length over the years, reflecting the increasing complexity of new medicines and a corresponding increase in the size of pharmaceutical company submissions. The interviews conducted to date suggest that the DADs are highly regarded and support implementation of new medicines advice by the ADTC. The findings of this evaluation will lead to an action plan for improvement.
Collateral status is an indicator of a favorable outcome in stroke. Leptomeningeal collaterals provide alternative routes for brain perfusion following an arterial occlusion or flow-limiting stenosis. Using a large cohort of ischemic stroke patients, we examined the relative contribution of various demographic, laboratory, and clinical variables in explaining variability in collateral status.
Methods:
Patients with acute ischemic stroke in the anterior circulation were enrolled in a multi-center hospital-based observational study. Intracranial occlusions and collateral status were identified and graded using multiphase computed tomography angiography. Based on the percentage of affected territory filled by collateral supply, collaterals were graded as either poor (0–49%), good (50–99%), or optimal (100%). Between-group differences in demographic, laboratory, and clinical factors were explored using ordinal regression models. Further, we explored the contribution of measured variables in explaining variance in collateral status.
Results:
386 patients with collateral status classified as poor (n = 64), good (n = 125), and optimal (n = 197) were included. Median time from symptom onset to CT was 120 (IQR: 78–246) minutes. In final multivariable model, male sex (OR 1.9, 95% CIs [1.2, 2.9], p = 0.005) and leukocytosis (OR 1.1, 95% CIs [1.1, 1.2], p = 0.001) were associated with poor collaterals. Measured variables only explained 44.8–53.0% of the observed between-patient variance in collaterals.
Conclusion:
Male sex and leukocytosis are associated with poorer collaterals. Nearly half of the variance in collateral flow remains unexplained and could be in part due to genetic differences.
We examined the return on investment (ROI) from the Endovascular Reperfusion Alberta (ERA) project, a provincially funded population-wide strategy to improve access to endovascular therapy (EVT), to inform policy regarding sustainability.
Methods:
We calculated net benefit (NB) as benefit minus cost and ROI as benefit divided by cost. Patients treated with EVT and their controls were identified from the ESCAPE trial. Using the provincial administrative databases, their health services utilization (HSU), including inpatient, outpatient, physician, long-term care services, and prescription drugs, were compared. This benefit was then extrapolated to the number of patients receiving EVT increased in 2018 and 2019 by the ERA implementation. We used three time horizons, including short (90 days), medium (1 year), and long-term (5 years).
Results:
EVT was associated with a reduced gross HSU cost for all the three time horizons. Given the total costs of ERA were $2.04 million in 2018 ($11,860/patient) and $3.73 million in 2019 ($17,070/patient), NB per patient in 2018 (2019) was estimated at −$7,313 (−$12,524), $54,592 ($49,381), and $47,070 ($41,859) for short, medium, and long-term time horizons, respectively. Total NB for the province in 2018 (2019) were −$1.26 (−$2.74), $9.40 ($10.78), and $8.11 ($9.14) million; ROI ratios were 0.4 (0.3), 5.6 (3.9) and 5.0 (3.5). Probabilities of ERA being cost saving were 39% (31%), 97% (96%), and 94% (91%), for short, medium, and long-term time horizons, respectively.
Conclusion:
The ERA program was cost saving in the medium and long-term time horizons. Results emphasized the importance of considering a broad range of HSU and long-term impact to capture the full ROI.
Composer-performer Julius Eastman (1940-90) was an enigma, both comfortable and uncomfortable in the many worlds he inhabited: black, white, gay, straight, classical music, disco, academia, and downtown New York. His music, insistent and straightforward, resists labels and seethes with a tension that resonates with musicians, scholars, and audiences today. Eastman's provocative titles, including Gay Guerrilla, Evil Nigger, Crazy Nigger, and others assault us with his obsessions. Eastman tested limits with his political aggressiveness, as recounted in legendary scandals he unleashed like his June 1975 performance of John Cage's Song Books, which featured homoerotic interjections, or the uproar over his titles at Northwestern University. These episodes areexamples of Eastman's persistence in pushing the limits of the acceptable in the highly charged arenas of sexual and civil rights.
In addition to analyses of Eastman's music, the essays in Gay Guerrilla provide background on his remarkable life history and the era's social landscape. The book presents an authentic portrait of a notable American artist that is compelling reading for the general reader as well as scholars interested in twentieth-century American music, American studies, gay rights, and civil rights.

During the Randomized Assessment of Rapid Endovascular Treatment (EVT) of Ischemic Stroke (ESCAPE) trial, patient-level micro-costing data were collected. We report a cost-effectiveness analysis of EVT, using ESCAPE trial data and Markov simulation, from a universal, single-payer system using a societal perspective over a patient’s lifetime.
Methods:
Primary data collection alongside the ESCAPE trial provided a 3-month trial-specific, non-model, based cost per quality-adjusted life year (QALY). A Markov model utilizing ongoing lifetime costs and life expectancy from the literature was built to simulate the cost per QALY adopting a lifetime horizon. Health states were defined using the modified Rankin Scale (mRS) scores. Uncertainty was explored using scenario analysis and probabilistic sensitivity analysis.
Results:
The 3-month trial-based analysis resulted in a cost per QALY of $201,243 of EVT compared to the best standard of care. In the model-based analysis, using a societal perspective and a lifetime horizon, EVT dominated the standard of care; EVT was both more effective and less costly than the standard of care (−$91). When the time horizon was shortened to 1 year, EVT remains cost savings compared to standard of care (∼$15,376 per QALY gained with EVT). However, if the estimate of clinical effectiveness is 4% less than that demonstrated in ESCAPE, EVT is no longer cost savings compared to standard of care.
Conclusions:
Results support the adoption of EVT as a treatment option for acute ischemic stroke, as the increase in costs associated with caring for EVT patients was recouped within the first year of stroke, and continued to provide cost savings over a patient’s lifetime.
Most textbooks on regression focus on theory and the simplest of examples. Real statistical problems, however, are complex and subtle. This is not a book about the theory of regression. It is about using regression to solve real problems of comparison, estimation, prediction, and causal inference. Unlike other books, it focuses on practical issues such as sample size and missing data and a wide range of goals and techniques. It jumps right in to methods and computer code you can use immediately. Real examples, real stories from the authors' experience demonstrate what regression can do and its limitations, with practical advice for understanding assumptions and implementing methods for experiments and observational studies. They make a smooth transition to logistic regression and GLM. The emphasis is on computation in R and Stan rather than derivations, with code available online. Graphics and presentation aid understanding of the models and model fitting.
Hamilcar and Hannibal Barca embody a colossal father-son military legacy. Yet their family – the so-called ‘Barcid’ dynasty – has a murky history. Modern scholars have presumed that Hamilcar, the first notable historical figure to bear the name Barkas, received it as a ‘nickname’ meaning ‘lightning’. The rationale is that the name derives from the Phoenician word brq and is thus the equivalent to the Greek epithet Keraunos. There is, however, no evidence in our classical sources, to which exclusively we owe our knowledge of events, supporting this. Furthermore, the name Barca was passed on to Hamilcar’s sons, something suggestive of an inherited family surname. This article submits an alternative to the widely endorsed ‘lightning’ theory. This new perspective explores the possibility that the Barcid dynasty had roots in the city of Barce in Cyrenaica and was a relatively new addition to the Carthaginian aristocracy in the third century BC. Using textual evidence from Polybius, Diodorus and others, this fresh take clarifies other aspects of the Barcid dynasty’s tumultuous history, such as their animosity towards the Carthaginian Council of Elders and their departure to Spain in the 220s.
Acute ischemic stroke may affect women and men differently. We aimed to evaluate sex differences in outcomes of endovascular treatment (EVT) for ischemic stroke due to large vessel occlusion in a population-based study in Alberta, Canada.
Methods and Results:
Over a 3-year period (April 2015–March 2018), 576 patients fit the inclusion criteria of our study and constituted the EVT group of our analysis. The medical treatment group of the ESCAPE trial had 150 patients. Thus, our total sample size was 726. We captured outcomes in clinical routine using administrative data and a linked database methodology. The primary outcome of our study was home-time. Home-time refers to the number of days that the patient was back at their premorbid living situation without an increase in the level of care within 90 days of the index stroke event. In adjusted analysis, EVT was associated with an increase of 90-day home-time by an average of 6.08 (95% CI −2.74–14.89, p-value 0.177) days in women compared to an average of 11.20 (95% CI 1.94–20.46, p-value 0.018) days in men. Further analysis revealed that the association between EVT and 90-day home-time in women was confounded by age and onset-to-treatment time.
Conclusions:
We found a nonsignificant nominal reduction of 90-day home-time gain for women compared to men in this province-wide population-based study of EVT for large vessel occlusion, which was only partially explained by confounding.
