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.
