- Intracranial bleedings caused by stroke or head trauma is a serious condition that need immediate medical care and interventions. Pre-hospital detection and diagnosis would constitute a major breakthrough in streamlining the care and in reducing the time from incidence to start of treatment. In this paper we present a numerical simulation study to investigate the detection capability of a machine learning algorithm and its performance when diagnosing patients with intracranial bleedings from healthy subjects, for example hemorrhagic stroke patients from healthy persons. The specific goal is to study the training phase of the classifier and how parameters, such as number of antennas, number of training samples, noise, etc. affect the ability to detect bleedings with different volumes. The detection performance is evaluated in a cross-validation scheme.

- BackgroundStudies have revealed low adherence to guidelines for treatment of diabetes and cardiovascular risk factors.ObjectiveTo explore general practitioners’ experiences regarding treatment practice in type 2 diabetes with specific focus on the prevention of cardiovascular disease.MethodsFourteen experienced general practitioners from nine health care centres with group practices were interviewed in focus groups. The interviews were digitally recorded, transcribed verbatim and analysed by qualitative content analysis.ResultsThe overall theme was “dilemmas” in GPs´ treatment practice for type 2 diabetes patients. Five main dilemma categories were identified. First, the GPs were hesitant about labelling someone who feels healthy as ill. Secondly, regarding communicating a diabetes diagnosis and its consequences; should the patient be frightened or comforted? Thirdly, the GPs experienced uncertainty in their role; were they to take responsibility for the care or not? Fourthly, the GPs expressed a conflict between lifestyle changes and drug treatment. Fifthly, the GPs described difficulties in integrating science into reality.ConclusionsThe five dilemmas in the general practitioners’ approach to diabetes patients and the treatment of their cardiovascular risk were related to the GPs´ professional role and communication with the patient. To consider these dilemmas in educational efforts is probably essential to achieve improved diabetes care and guideline adherence.

Body image in patients with residual eating disorder symptoms : treatment effects of acceptance and commitment therapy and participants' reflections
- 2021
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The overall aim of this thesis was to evaluate an acceptance and commitment (ACT) group intervention targeting body image in patients with residual eating disorder (ED) symptoms, including treatment effects and participants’ reflections on body image and the intervention. Studies I, II and III are based on a randomized controlled trial including 99 patients that were randomized to the ACT intervention or to continue treatment as usual (TAU). Different self-assessment questionnaires were administered before and after the intervention and at follow up by one and two years. Study IV is based on interviews with patients that had completed the intervention, and did not participate in the trial. From written evaluations in study I body image was shown to mean different things for different individuals. This was also shown by different expectations on treatment. Study II showed that the ACT intervention was superior to TAU in reducing ED symptoms and body dissatisfaction, while care consumption was lower. In addition, ratings of dropout was low. In study III, it was shown that symptom improvement from the ACT intervention rather than TAU was more pronounced in participants with restrictive ED psychopathology. Participants who displayed binge eating and/or purging ED psychopathology, showed improvement on ED symptoms regardless of intervention. Participants younger than 25, and with lower ratings at baseline, showed no improvement on ED symptoms if continuing with TAU. From interviews with participants in study IV, the intervention was described as demanding, and participants described the importance of their own efforts. Specific processes of the intervention were helpful and the context of the group and context outside of treatment could facilitate or hinder progress. Perceived changes in body image differed between participants in study I, showing the potential breadth of the intervention.Conclusions from this thesis was that an intervention based on ACT targeting body image was suitable and helpful for patients with residual EDsymptoms. Though the intervention was demanding, dropout was low, and specific processes were described as helpful.

- Background The Global Burden of Diseases, Injuries, and Risk Factors Study 2015 provides an up-to-date synthesis of the evidence for risk factor exposure and the attributable burden of disease. By providing national and subnational assessments spanning the past 25 years, this study can inform debates on the importance of addressing risks in context.Methods We used the comparative risk assessment framework developed for previous iterations of the Global Burden of Disease Study to estimate attributable deaths, disability-adjusted life-years (DALYs), and trends in exposure by age group, sex, year, and geography for 79 behavioural, environmental and occupational, and metabolic risks or clusters of risks from 1990 to 2015. This study included 388 risk-outcome pairs that met World Cancer Research Fund-defined criteria for convincing or probable evidence. We extracted relative risk and exposure estimates from randomised controlled trials, cohorts, pooled cohorts, household surveys, census data, satellite data, and other sources. We used statistical models to pool data, adjust for bias, and incorporate covariates. We developed a metric that allows comparisons of exposure across risk factors-the summary exposure value. Using the counterfactual scenario of theoretical minimum risk level, we estimated the portion of deaths and DALYs that could be attributed to a given risk. We decomposed trends in attributable burden into contributions from population growth, population age structure, risk exposure, and risk-deleted cause-specific DALY rates. We characterised risk exposure in relation to a Socio-demographic Index (SDI).Findings Between 1990 and 2015, global exposure to unsafe sanitation, household air pollution, childhood underweight, childhood stunting, and smoking each decreased by more than 25%. Global exposure for several occupational risks, high body-mass index (BMI), and drug use increased by more than 25% over the same period. All risks jointly evaluated in 2015 accounted for 57.8% (95% CI 56.6-58.8) of global deaths and 41.2% (39.8-42.8) of DALYs. In 2015, the ten largest contributors to global DALYs among Level 3 risks were high systolic blood pressure (211.8 million [192.7 million to 231.1 million] global DALYs), smoking (148.6 million [134.2 million to 163.1 million]), high fasting plasma glucose (143.1 million [125.1 million to 163.5 million]), high BMI (120.1 million [83.8 million to 158.4 million]), childhood undernutrition (113.3 million [103.9 million to 123.4 million]), ambient particulate matter (103.1 million [90.8 million to 115.1 million]), high total cholesterol (88.7 million [74.6 million to 105.7 million]), household air pollution (85.6 million [66.7 million to 106.1 million]), alcohol use (85.0 million [77.2 million to 93.0 million]), and diets high in sodium (83.0 million [49.3 million to 127.5 million]). From 1990 to 2015, attributable DALYs declined for micronutrient deficiencies, childhood undernutrition, unsafe sanitation and water, and household air pollution; reductions in risk-deleted DALY rates rather than reductions in exposure drove these declines. Rising exposure contributed to notable increases in attributable DALYs from high BMI, high fasting plasma glucose, occupational carcinogens, and drug use. Environmental risks and childhood undernutrition declined steadily with SDI; low physical activity, high BMI, and high fasting plasma glucose increased with SDI. In 119 countries, metabolic risks, such as high BMI and fasting plasma glucose, contributed the most attributable DALYs in 2015. Regionally, smoking still ranked among the leading five risk factors for attributable DALYs in 109 countries; childhood underweight and unsafe sex remained primary drivers of early death and disability in much of sub-Saharan Africa.Interpretation Declines in some key environmental risks have contributed to declines in critical infectious diseases. Some risks appear to be invariant to SDI. Increasing risks, including high BMI, high fasting plasma glucose, drug use, and some occupational exposures, contribute to rising burden from some conditions, but also provide opportunities for intervention. Some highly preventable risks, such as smoking, remain major causes of attributable DALYs, even as exposure is declining. Public policy makers need to pay attention to the risks that are increasingly major contributors to global burden.

- BackgroundVirtual patients (VPs) can be used to assess clinical reasoning. Grading metrics applied to VP exams may include scoring for appropriate differential diagnoses, proposed therapy, and the learner’s approach to the case. The learner’s inquiry of medical history, physical exam, and lab/ancillary tests utilized during the exam can all be graded. However, the best grading metric used to assess clinical reasoning for VP examination is unresolved. Summary of WorkResults from two groups of students assessed by VP-based examination (n>300) were used as a basis to evaluate different grading metrics. These grading models were also compared with results of other traditional student examination performance. Summary of ResultsEach method of grading had both pronounced advantages and disadvantages with none considered ideal. However one grading metric was perceived to perform slightly better. None of the scoring methods had a direct correlation with four traditional exam formats to which they were compared. ConclusionsEach grading metric used in this study had advantages and disadvantages. Medical school exams employing VP-based exams need to define what should be assessed for reliable utilization.Take-home Messages Objectives of VP-based examination are essential to measure learner competency in an appropriate context. Traditional exams do not necessarily measure the same aptitude that VP-based exams measure.
