Harnessing the Power of an Extensive EMS-Induced Sorghum Population for Rapid Crop Improvement.

Plant breeders leverage mutagenesis using chemical, biological, and physical mutagens to create novel trait variations. Many widely used sorghum genotypes have a narrow genetic base, which hinders improvements using classical breeding. Enhancing the diversity of the sorghum genome thus remains a key priority for sorghum breeders. To accelerate the genetic enhancement of sorghum, an extensive library comprised of seeds from 150,000 individual mutant plants of the Sorghum bicolor inbred line BTx623 was established using ethyl methanesulphonate (EMS) as a mutagen. The sorghum mutant library was bulked into 1498 pools (~100 seed heads per pool). In each pool, DNA was extracted from a subset of the seed and screened using the FIND-IT technology based on droplet digital PCR. All 43 nucleotide substitutions that were screened using FIND-IT were identified, demonstrating the potential to identify any EMS-derived mutation in an elite line of sorghum within days. This diverse library represents the largest collection of sorghum mutants ever conceived, estimated to cover 240% of all possible EMS-induced mutation points within the Sorghum genome. Using FIND-IT, the speed at which a specific desired EMS-derived mutation can be identified is a major upgrade to conventional reverse genetic techniques. Additionally, the ease at which valuable variants can be integrated into elite commercial lines is a far simpler and less expensive process compared to genome editing. Genomic variations in the library will have direct utility as a breeding resource for commercial sorghum applications, allowing enhanced adaptation to climate change and enhanced yield potential in marginal environments.

Adverse events reporting during the COVID-19 pandemic in a Danish region: a retrospective analysis.

The 2020 onset of the COVID-19 pandemic globally strained healthcare. Healthcare systems worldwide had to rapidly reorganize, impacting service delivery, patient care, and care-seeking behaviors. This left little time to assess the pandemic's effects on patient safety. This paper investigates COVID-19's influence on patient safety in a Danish region, using data from the national reporting system for adverse events during the initial COVID-19 surge in early 2020. This retrospective analysis investigated how the early phase of the COVID-19 pandemic (January-September 2020) affected the incidence of adverse events in a Danish Region, comparing it to the same period in 2019. Data were sourced from the Danish Patient Safety Database and regional systems. Adverse events were reported numerically. Descriptive statistics were employed to describe the percentage difference in adverse events and hospital activity, as well as the rate of adverse events per 1000 activities. Additionally, COVID-19-specific adverse events from April 2020 to March 2021 were identified and analyzed, categorizing them into seven risk areas across various healthcare sectors. During Denmark's initial COVID-19 surge in early 2020, the North Denmark Region's hospitals reported a significant decrease in adverse events, with a 42.5% drop in March 2020 compared to March 2019. From January to September 2020, the number of adverse events dropped 8.5% compared to the same period in 2019. In the same period, hospital activity declined by 10.2%. The ratio of reported adverse events per 1000 hospital activities thus decreased in early 2020 but showed only a minor difference overall for January-September compared to 2019. Between April 2020 and March 2021, out of 5703 total adverse events, 324 (5.7%) were COVID-19 related. COVID-19-related events were categorized into seven distinct risk areas, reflecting diverse impacts across healthcare sectors including hospitals, general practices, pre-hospital care, and specialized services. The initial decline in reporting of adverse events likely resulted from rapid healthcare changes and under-prioritization of the reporting system during the acute phase. However, a near return to pre-pandemic reporting levels suggests a resilient reporting system despite the crisis. The study's strength lies in the comprehensive data from Danish reporting systems, though it acknowledges potential underreporting and doesn't measure the pandemic's overall impact on patient safety.

Accelerated Domestication of New Crops: Yield is Key.

Sustainable agriculture in the future will depend on crops that are tolerant to biotic and abiotic stresses, require minimal input of water and nutrients and can be cultivated with a minimal carbon footprint. Wild plants that fulfill these requirements abound in nature but are typically low yielding. Thus, replacing current high-yielding crops with less productive but resilient species will require the intractable trade-off of increasing land area under cultivation to produce the same yield. Cultivating more land reduces natural resources, reduces biodiversity and increases our carbon footprint. Sustainable intensification can be achieved by increasing the yield of underutilized or wild plant species that are already resilient, but achieving this goal by conventional breeding programs may be a long-term prospect. De novo domestication of orphan or crop wild relatives using mutagenesis is an alternative and fast approach to achieve resilient crops with high yields. With new precise molecular techniques, it should be possible to reach economically sustainable yields in a much shorter period of time than ever before in the history of agriculture.

From accreditation to quality improvement-The Danish National Quality Programme.

The Danish government launched a new National Quality Programme (NQP) in healthcare in 2015. It has changed the focus from old public management in terms of accreditation, regulation, rules and standards to new public governance focusing on delivering high quality healthcare and outcomes of value for the patients, health professionals and the Danish healthcare system. The NQP aims to strengthen the focus on continuous quality improvement and the launch of the programme was accompanied by a decision to phase out accreditation of public hospitals. The NQP includes 1) eight specific national quality goals, 2) a national educational programme for quality management, and 3) establishment of quality improvement collaboratives. Since the establishment of the NQP the indicator results have improved in several important clinical areas. However, causal conclusions related to the effect of the NQP cannot yet be made. This perspective on quality paper aims to give a short introduction to the NQP and documented outcomes.

Renal protection: What have we learnt from ADVANCE about kidney disease in type 2 diabetes?

The Action in Diabetes and Vascular Disease: Preterax and Diamicron Modified Release Controlled Evaluation (ADVANCE) factorial trial was a landmark randomized controlled clinical trial in 11 140 type 2 diabetic patients from 215 centers in 20 countries with a two-by-two factorial design. In the blood pressure-lowering arm, patients were treated using a fixed combination of the ACE-inhibitor, perindopril, and the thiazide-like diuretic, indapamide, or placebo, whereas in the glucose-lowering arm, the intervention compared the sulphonylurea gliclazide plus other glucose-lowering drugs, targeting a glycated hemoglobin value of 6.5% or less, with standard glucose control. Primary end-points were major macro- and microvascular events in both arms. This review gives an overview of the results of the primary randomized trial, results from observational follow-up studies, and results of several biomarker studies and discusses the perspectives of these data in the context of recent major outcome trials for current medical treatment.

Quality in practice: applying the patient inventory method at a Danish psychiatric hospital.

QUALITY PROBLEM: Patient care pathways should be organized according to the needs of the patients. This requires methods to assess whether the specific pathways ensure the right care for the right person at the right time and in the right setting. INITIAL ASSESSMENT: Previous investigations indicate that ~25% of the patients in Danish hospitals experience inappropriate elements in their care pathways. CHOICE OF SOLUTION: This study applied the Patient Inventory method to identify inappropriate elements in care pathways in 15 psychiatric in-patient wards in Denmark. IMPLEMENTATION: The pathway for 201 patients was systematically evaluated by the clinical staff to identify whether the admission of the patient was avoidable, the hospitalization was unnecessarily prolonged or if the patient could receive more relevant treatment elsewhere. A subsequent meeting between the clinical staff and management qualified the assessment and identified possible solutions to problems. EVALUATION: A total of 54 (26.9%) of the included patients were assessed to have inappropriate elements in their care pathways, some with more than one type, resulting in a total of 65 episodes.Eight of these episodes (13.1%) were admissions considered to be avoidable, 26 (42.2%) were unnecessary prolongation of admissions, and 31 (58.1%) were patients assessed to be able to receive more relevant care elsewhere. LESSONS LEARNED: One out of four assessed patients admitted to a psychiatric ward was exposed to an inappropriate element in their care pathway. The Patient Inventory tool can assist in a structured dialogue between clinical staff and management to identify focus areas for improvement efforts.

Patient Inventory: a quality improvement method.

Providing high quality care requires that patient care pathways are organized according to the needs of the patient. The organization of high-quality integrated patient care requires methods to assess 'appropriateness' of the care pathways to identify challenges in delivering the right procedure, for the right person at the right time and setting and with the most appropriate use of resources. There is a need for methods to assess appropriateness that can easily be implemented in daily clinical practice. The Patient Inventory method is such a method. Patient Inventory is a special type of audit that provides a 'snapshot' of the patient population in an entire hospital, a ward or another clinical unit. It maps the bed occupancy situation, as well as coordination, continuity and communication associated with the individual patient pathway. The aim is to identify inappropriate or wasteful events and to facilitate reflections on the underlying causes. These reflections are used to identify focus areas for quality improvement efforts. The method answers the question: 'Is it the right patient in the right place at the right time, and is the correct pathway for the patient organized with the most appropriate use of resources?' The aim of this method paper is to describe the background, definitions and methodologies for Patient Inventory, to offer a practical guidance for application of the method and to describe the current experiences with the method.

Can quality improvement improve the quality of care? A systematic review of reported effects and methodological rigor in plan-do-study-act projects.

BACKGROUND: The Plan-Do-Study-Act (PDSA) method is widely used in quality improvement (QI) strategies. However, previous studies have indicated that methodological problems are frequent in PDSA-based QI projects. Furthermore, it has been difficult to establish an association between the use of PDSA and improvements in clinical practices and patient outcomes. The aim of this systematic review was to examine whether recently published PDSA-based QI projects show self-reported effects and are conducted according to key features of the method. METHODS: A systematic literature search was performed in the PubMed, Embase and CINAHL databases. QI projects using PDSA published in peer-reviewed journals in 2015 and 2016 were included. Projects were assessed to determine the reported effects and the use of the following key methodological features; iterative cyclic method, continuous data collection, small-scale testing and use of a theoretical rationale. RESULTS: Of the 120 QI projects included, almost all reported improvement (98%). However, only 32 (27%) described a specific, quantitative aim and reached it. A total of 72 projects (60%) documented PDSA cycles sufficiently for inclusion in a full analysis of key features. Of these only three (4%) adhered to all four key methodological features. CONCLUSION: Even though a majority of the QI projects reported improvements, the widespread challenges with low adherence to key methodological features in the individual projects pose a challenge for the legitimacy of PDSA-based QI. This review indicates that there is a continued need for improvement in quality improvement methodology.

A European, multicentre, retrospective, non-interventional study (EU-TREAT) of the effectiveness of insulin degludec after switching basal insulin in a population with type 1 or type 2 diabetes.

AIMS: To evaluate the clinical effectiveness of switching to insulin degludec (IDeg) in insulin-treated patients with either type 1 diabetes (T1DM) or type 2 diabetes (T2DM) under conditions of routine clinical care. MATERIALS AND METHODS: This was a multicentre, retrospective, chart review study. In all patients, basal insulin was switched to IDeg at least 6 months before the start of data collection. Baseline was defined as the most recent recording during the 3-month period before first prescription of IDeg. Values are presented as mean [95%CI]. RESULTS: T1DM (n = 1717): HbA1c decreased by -2.2 [-2.6; -2.0] mmol/mol (-0.20 [-0.24; -0.17]%) at 6 months vs baseline (P < .001). Rate ratio of overall (0.79 [0.69; 0.89]), non-severe nocturnal (0.54 [0.42; 0.69]) and severe (0.15 [0.09; 0.24]) hypoglycaemia was significantly lower in the 6-month post-switch period vs the pre-switch period (P < .001 for all). Total daily insulin dose decreased by -4.88 [-5.52; -4.24] U (-11%) at 6 months vs baseline (P < .001). T2DM (n = 833): HbA1c decreased by -5.6 [-6.3; -4.7] mmol/mol (-0.51 [-0.58; -0.43] %) at 6 months vs baseline (P < .001). Rate ratio of overall (0.39 [0.27; 0.58], P < .001), non-severe nocturnal (0.10 [0.06; 0.16], P < .001) and severe (0.075 [0.01; 0.43], P = .004) hypoglycaemia was significantly lower in the 6-month post-switch period vs the pre-switch period. Total daily insulin dose decreased by -2.48 [-4.24; -0.71] U (-3%) at 6 months vs baseline (P = .006). Clinical outcomes for T1DM and T2DM at 12 months were consistent with results at 6 months. CONCLUSIONS: This study demonstrates that switching patients to IDeg from other basal insulins improves glycaemic control and significantly reduces the risk of hypoglycaemia in routine clinical practice.

The Danish cancer pathway for patients with serious non-specific symptoms and signs of cancer-a cross-sectional study of patient characteristics and cancer probability.

BACKGROUND: A Danish cancer pathway has been implemented for patients with serious non-specific symptoms and signs of cancer (NSSC-CPP). The initiative is one of several to improve the long diagnostic interval and the poor survival of Danish cancer patients. However, little is known about the patients investigated under this pathway. We aim to describe the characteristics of patients referred from general practice to the NSSC-CPP and to estimate the cancer probability and distribution in this population. METHODS: A cross-sectional study was performed, including all patients referred to the NSSC-CPP at the hospitals in Aarhus or Silkeborg in the Central Denmark Region between March 2012 and March 2013. Data were based on a questionnaire completed by the patient's general practitioner (GP) combined with nationwide registers. Cancer probability was the percentage of new cancers per investigated patient. Associations between patient characteristics and cancer diagnosis were estimated with prevalence rate ratios (PRRs) from a generalised linear model. RESULTS: The mean age of all 1278 included patients was 65.9 years, and 47.5 % were men. In total, 16.2 % of all patients had a cancer diagnosis after six months; the most common types were lung cancer (17.9 %), colorectal cancer (12.6 %), hematopoietic tissue cancer (10.1 %) and pancreatic cancer (9.2 %). All patients in combination had more than 80 different symptoms and 51 different clinical findings at referral. Most symptoms were non-specific and vague; weight loss and fatigue were present in more than half of all cases. The three most common clinical findings were 'affected general condition' (35.8 %), 'GP's gut feeling' (22.5 %) and 'findings from the abdomen' (13.0 %). A strong association was found between GP-estimated cancer risk at referral and probability of cancer. CONCLUSIONS: In total, 16.2 % of the patients referred through the NSSC-CPP had cancer. They constituted a heterogeneous group with many different symptoms and clinical findings. The GP's gut feeling was a common reason for referral which proved to be a strong predictor of cancer. The GP's overall estimation of the patient's risk of cancer at referral was associated with the probability of finding cancer.

Morning blood pressure surge and target organ damage in newly diagnosed type 2 diabetic patients: a cross sectional study.

BACKGROUND: Type 2 diabetic patients display significantly higher incidence of cardiovascular (CV) events including stroke compared to non-diabetics. Morning blood pressure surge (MBPS) and blunted systolic night-day (SND) ratio have been associated with CV events in hypertensive patients. No studies have evaluated MBPS in newly diagnosed diabetic patients or studied the association with vascular target organ damage at this early time point of the diabetes disease. METHODS: Ambulatory blood pressure monitoring was performed in 100 patients with newly diagnosed type 2 diabetes and 100 age and sex matched controls. MBPS and SND-ratio were calculated. Markers of early vascular target organ damage included pulse wave velocity (PWV), white matter lesions (WML) on brain MRI, and urine albumin/creatinine ratio (UAE). RESULTS: No significant differences in MBPS were found between diabetic patients and controls. Neither MBPS or SND-ratio were associated with PWV, UAE or WML in the diabetic group independently of age, gender and 24-h systolic blood pressure. 40.2 % of diabetic patients and 25.8 % of controls were classified as non-dippers (p = 0.03). CONCLUSION: MBPS and SND-ratio are not associated with subclinical markers of vascular target organ damage in our study sample of newly diagnosed type 2 diabetic patients.

Improvement of mild retinopathy in type 2 diabetic patients correlates with narrowing of retinal arterioles. A prospective observational study.

PURPOSE: Diabetic retinopathy is one of the leading causes of blindness in the Western world. The disease is characterized by morphological lesions secondary to disturbances in retinal blood flow assumed to be related to disturbances in retinal autoregulation. However, there is a need for elucidating the relation between disturbances in diameter regulation of retinal vessels and the development of diabetic retinopathy in longitudinal studies. METHODS: Sixty-four patients with type 2 diabetes mellitus were subjected to measurement of pressure autoregulation of retinal arterioles using the Dynamic Vessel Analyzer (DVA) and measurement of retinal thickness using OCT scanning, and after a mean of 6.8 years, 42 of the patients were re-examined. The vascular response was compared in patients in whom retinopathy had disappeared, was unchanged, or had worsened. RESULTS: At baseline, hemoglobin A1c (HbA1c) was significantly higher in the patients who would later experience worsening of diabetic retinopathy than in the other groups, but had been reduced at the follow-up examination. During the follow-up period, the resting diameter of retinal arterioles decreased significantly in the patients who experienced improvement in diabetic retinopathy but was unchanged in the other groups, whereas both the diameter response of retinal arterioles to isometric exercise and retinal thickness increased non-significantly with worsening of retinopathy. CONCLUSIONS: The development of diabetic retinopathy is related to the diameter of retinal arterioles. Future clinical intervention studies should aim at investigating the effects of normalizing arteriolar diameters in diabetic retinopathy.

Diabetic retinopathy.

Diabetic retinopathy (DR) is the most common complication in patients with diabetes, and screening for sight-threatening end-stages is indicated to avoid severe visual loss. Screening of DR is nationally implemented in Denmark according to evidence-based national guidelines, which includes the use of individualised screening intervals. Treatment is indicated for proliferative DR and diabetic macular oedema, and treatment modalities include retinal laser therapy, intravitreal angiostatic therapy, and vitrectomy. In this review, we summarise the current guidelines for screening and treatment of DR in Denmark.

Challenges and Opportunities in Data Visualization Education: A Call to Action.

This paper is a call to action for research and discussion on data visualization education. As visualization evolves and spreads through our professional and personal lives, we need to understand how to support and empower a broad and diverse community of learners in visualization. Data Visualization is a diverse and dynamic discipline that combines knowledge from different fields, is tailored to suit diverse audiences and contexts, and frequently incorporates tacit knowledge. This complex nature leads to a series of interrelated challenges for data visualization education. Driven by a lack of consolidated knowledge, overview, and orientation for visualization education, the 21 authors of this paper-educators and researchers in data visualization-identify and describe 19 challenges informed by our collective practical experience. We organize these challenges around seven themes People, Goals & Assessment, Environment, Motivation, Methods, Materials, and Change. Across these themes, we formulate 43 research questions to address these challenges. As part of our call to action, we then conclude with 5 cross-cutting opportunities and respective action items: embrace DIVERSITY+INCLUSION, build COMMUNITIES, conduct RESEARCH, act AGILE, and relish RESPONSIBILITY. We aim to inspire researchers, educators and learners to drive visualization education forward and discuss why, how, who and where we educate, as we learn to use visualization to address challenges across many scales and many domains in a rapidly changing world: viseducationchallenges.github.io.

Acute hyperinsulinemia increases the contraction of retinal arterioles induced by elevated blood pressure.

Diabetic retinopathy is accompanied by disturbances in retinal blood flow, which is assumed to be related to the diabetic metabolic dysregulation. It has previously been shown that normoinsulinemic hyperglycemia has no effect on the diameter of retinal arterioles at rest and during an increase in the arterial blood pressure induced by isometric exercise. However, the influence of hyperinsulinemia on this response has not been studied in detail. In seven normal persons, the diameter response of retinal arterioles to an increased blood pressure induced by isometric exercise, to stimulation with flickering light, and to the combination of these stimuli was studied during euglycemic normoinsulinemia (protocol N) on one examination day, and euglycemic hyperinsulinemia (protocol H) on another examination day. Isometric exercise induced significant contraction of retinal arterioles at all examinations, but during a repeated examination the diameter response was significantly reduced in the test persons following the N protocol and increased in the persons following the H protocol. Flicker stimulation induced a significant dilatation of retinal arterioles at all examinations, and the response was significantly higher during a repeated examination, irrespective of the insulin level. Repeated exposure to isometric exercise reduces contraction, whereas repeated exposure to flickering light increases dilatation of retinal arterioles in vivo. Hyperinsulinemia increases contraction of retinal arterioles induced by isometric exercise.

Plasma levels of the arterial wall protein fibulin-1 are associated with carotid-femoral pulse wave velocity: a cross-sectional study.

BACKGROUND: The arterial system in diabetic patients is characterized by generalized non-atherosclerotic alterations in the vascular extracellular matrix causing increased arterial stiffness compared with subjects without diabetes. The underlying pathophysiology remains elusive. The elastin-associated extracellular matrix protein, fibulin-1, was recently found in higher concentrations in the arterial wall and in plasma in patients with long duration type 2 diabetes. Furthermore, plasma fibulin-1 independently predicted total mortality and was associated with pulse pressure, an indirect measure of arterial stiffness. Whether plasma fibulin-1 is associated with arterial stiffness at earlier phases of type 2 diabetes has not been determined. METHODS: In this cross-sectional study, we examined 90 patients with recently diagnosed type 2 diabetes (< 5 years) and 90 gender- and age-matched controls. Plasma fibulin-1 was measured immunochemically. Arterial stiffness was assessed by carotid-femoral Pulse Wave Velocity (PWV). Differences in means were assessed by t-tests. Associations were assessed by multivariate regression analyses. RESULTS: Plasma fibulin-1 levels were lower in the diabetic group compared with the control group, 93 ± 28 vs 106 ± 30 µg/mL, p = 0.005. In unadjusted analysis of the total study sample, plasma fibulin-1 was not associated with PWV, p = 0.46. However, with adjustment for the confounders age, gender, mean blood pressure, heart rate, body mass index, diabetes and glomerular filtration rate, a 10 µg/mL increase in plasma fibulin was associated with 0.09 ± 0.04 m/s increase in PWV, p < 0.05. In subgroup analysis, plasma fibulin-1 was associated with PWV in the diabetes group, (0.16 ± 0.07 m/s increase in PWV per 10 µg/mL increase in plasma fibulin-1, p<0.05), but not controls, ß = 0.021 ± 0.057 m/s per 10 µg/mL, p = 0.70. The association remained significant in the diabetes group after adjustment for covariates, p < 0.05. CONCLUSIONS: Plasma fibulin-1 is independently associated with PWV. Yet, as the plasma level of fibulin-1 was lower in patients with recently diagnosed type 2 diabetes than in healthy controls, plasma fibulin-1 levels are not a simple marker of the degree of arterial stiffening. Further studies are needed to determine the exact role of fibulin-1 in arterial stiffness and cardiovascular risk in patients with type 2 diabetes.

Reproducibility of pulse wave analysis and pulse wave velocity in patients with type 2 diabetes.

AIMS: Patients with type 2 diabetes have increased arterial stiffness and a high incidence of cardiovascular disease compared with non-diabetics. Arterial stiffness and central waveforms can be assessed by carotid-femoral pulse wave velocity (PWV) and pulse wave analysis (PWA) using the SphygmoCor device. These methods can potentially improve cardiovascular risk stratification in the future. However, a prerequisite is acceptable reproducibility. The objective of this study was to assess the intra- and inter-observer reproducibility of PWV and PWA indices in patients with type 2 diabetes using the SphygmoCor device. METHODS: Two trained observers (A and B) each undertook two PWA and two carotid-femoral PWV recordings in random order in 20 patients with type 2 diabetes under standardized conditions on the right side of the patients. Observer A also made double recordings on the left side. The mean of the two recordings was used for inter-observer comparison. Data were analyzed by Bland-Altman plots. RESULTS: The mean intra-observer differences (± 2SD) on the right side for observer A and B, respectively, were 0.0 ± 2.8 mmHg and 0.3 ± 3.2 mmHg (aortic systolic blood pressue (BP)), 0.0 ± 1.2 mmHg and 0.1 ± 1.0 mmHg (aortic diastolic BP), - 1.1 ± 3.2% and 1.1 ± 9.6% (central augmentation index (Aix)), - 1.6 ± 6.6% and 0.1 ± 9.0% (Aix normalized to heart rate 75 beats/min (Aix@HR75)) and 0.1 ± 1.8 m/s and 0.0 ± 1.6 m/s (PWV). The mean inter-observer differences (± 2SD) were - 2.6 ± 13.0 mmHg (aortic systolic BP), - 2.1 ± 7.4 mmHg (aortic diastolic BP), - 0.8 ± 8.4% (Aix), - 1.5 ± 7.4% (Aix@HR75) and - 0.3 ± 1.6 m/s (PWV). Left-vs-right comparison showed comparable results (observer A). CONCLUSIONS: PWA and PWV assessed with the SphygmoCor device are characterized by good reproducibility in patients with type 2 diabetes.

Highly effective mlo-based powdery mildew resistance in hexaploid wheat without pleiotropic effects.

Application of the mlo-based resistance in barley against powdery mildew attacks is a major success in crop breeding, since it confers durable disease resistance. Resistance caused by mutations in the Mlo gene seems to be ubiquitous across a range of species. This work addresses the introduction of mlo-based resistance into hexaploid wheat, which is complicated by the occurrence of three homoeologous genes: Mlo-A1, Mlo-B1 and Mlo-D1. EMS-generated mutant plants were screened for mutations in the three homoeologues. We selected and combined 6, 8, and 4 mutations, respectively, to obtain triple homozygous mlo mutant lines. Twenty-four mutant lines showed highly effective resistance towards attack by the powdery mildew pathogen under field conditions. All 18 mutations appeared to contribute to resistance; however, they had different effects on the occurrence of symptoms such as chlorotic and necrotic spots, which are pleiotropic to the mlo-based powdery mildew resistance. We conclude that to obtain highly effective powdery mildew resistance in wheat and to avoid detrimental pleiotropic effects, all three Mlo homoeologues should be mutated; however, at least one of the mutations should be of the weaker type in order to alleviate strong pleiotropic effects from the other mutations.

Multi-morbid patients with co-existing mental and physical illness.

This review investigates the mortality gap that exists between people with or people without mental illness. Poor physical health is the leading cause of excess mortality among people with mental illness. Mental disorders increase the risk of developing a broad range of physical diseases and the risk of death caused by somatic diseases is increased. Also, mental disorder is associated with less optimal treatment in the somatic healthcare system, which is also evident within a broad spectrum of somatic diseases. The role of structural factors such as the design of the healthcare system and stigma are developing.
