Renal Medulla in Hypertension.

Studies have found that blood flow to the renal medulla is an important determinant of pressure-natriuresis and the long-term regulation of arterial pressure. First, a brief review of methods developed enabling the study of the medullary circulation is presented. Second, studies performed in rats are presented showing medullary blood flow plays a vital role in the pressure-natriuresis relationship and thereby in hypertension. Third, it is shown that chronic reduction of medullary blood flow results in hypertension and that enhancement of medullary blood flow reduces hypertension hereditary models of both salt-sensitive rats and salt-resistant forms of hypertension. The key role that medullary nitric oxide production plays in protecting this region from ischemic injury associated with circulating vasoconstrictor agents and reactive oxygen species is presented. The studies cited are largely the work of my students, research fellows, and colleagues with whom I have performed these studies dating from the late 1980s to more recent years.

Strategies that facilitate the delivery of exceptionally good patient care in general practice: a qualitative study with patients and primary care professionals.

BACKGROUND: In recent years, proactive strengths-based approaches to improving quality of care have been advocated. The positive deviance approach seeks to identify and learn from those who perform exceptionally well. Central to this approach is the identification of the specific strategies, behaviours, tools and contextual strategies used by those positive deviants to perform exceptionally well. This study aimed to: identify and collate the specific strategies, behaviours, processes and tools used to support the delivery of exceptionally good care in general practice; and to abstract the identified strategies into an existing framework pertaining to excellence in general practice; the Identifying and Disseminating the Exceptional to Achieve Learning (IDEAL) framework. METHODS: This study comprised a secondary analysis of data collected during semi-structured interviews with 33 purposively sampled patients, general practitioners, practice nurses, and practice managers. Discussions explored the key factors and strategies that support the delivery of exceptional care across five levels of the primary care system; the patient, provider, team, practice, and external environment. For analysis, a summative content analysis approach was undertaken whereby data were inductively analysed and summated to identify the key strategies used to achieve the delivery of exceptionally good general practice care, which were subsequently abstracted as a new level of the IDEAL framework. RESULTS: In total, 222 individual factors contributing to exceptional care delivery were collated and abstracted into the framework. These included specific behaviours (e.g., patients providing useful feedback and personal history to the provider), structures (e.g., using technology effectively to support care delivery (e.g., electronic referrals & prescriptions)), processes (e.g., being proactive in managing patient flow and investigating consistently delayed wait times), and contextual factors (e.g., valuing and respecting contributions of every team member). CONCLUSION: The addition of concrete and contextual strategies to the IDEAL framework has enhanced its practicality and usefulness for supporting improvement in general practices. Now, a multi-level systems approach is needed to embed these strategies and create an environment where excellence is supported. The refined framework should be developed into a learning tool to support teams in general practice to measure, reflect and improve care within their practice.

Exertional Heatstroke Survivors' Knowledge and Beliefs about Exertional Heatstroke Diagnosis, Treatment, and Return to Play.

CONTEXT: Little information exists regarding what exertional heatstroke (EHS) survivors know and believe about EHS best practices. Understanding this would help clinicians focus educational efforts to ensure survival and safe return-to-play following EHS. OBJECTIVE: We sought to better understand what EHS survivors knew about EHS seriousness (e.g., lethality, short- and long-term effects), diagnosis and treatment procedures, and recovery. Design: Multi-year, cross-sectional, descriptive design. SETTING: An 11.3-km road race located in the Northeastern United States in August 2022 and 2023. PATIENTS OR OTHER PARTICIPANTS: Forty-two of 62 runners with EHS (15 women, 27 men; age: 33±15 y; pre-treatment rectal temperature [TREC]: 41.5±0.9°C). INTERVENTIONS: Medical professionals evaluated runners requiring medical attention at the finish line. If they observed TREC ≥40°C with concomitant central nervous system dysfunction (CNS) EHS was diagnosed and patients were immersed in a 189.3-L tub filled with ice-water. Before medical discharge, we asked EHS survivors 15 questions about their experience and knowledge of select EHS best practices. Survey items were piloted and validated by experts and laypersons a priori (content validity index ≥0.88 for items and scale). MAIN OUTCOME MEASURES: Survey responses. RESULTS: Sixty-seven percent (28/42) of patients identified EHS as potentially fatal and 76% (32/42) indicated it negatively affected health. Seventy-nine percent (33/42) correctly identified TREC as the best temperature site to diagnose EHS. Most patients (74%, 31/42) anticipated returning to normal exercise within 1 week post-EHS; 69% (29/42) stated EHS would not impact future race participation. Patients (69%, 29/42) indicated it was important to tell their primary care physician about their EHS. CONCLUSIONS: Our patients were knowledgeable on the potential seriousness and adverse health effects of EHS and the necessity of TREC for diagnosis. However, educational efforts should be directed towards helping patients understand safe recovery and return-to-play timelines following EHS.

A cognitive task analysis of final year nursing students' situation awareness in simulated deteriorating patient events: A mixed methods study.

AIM: The aim of this study was to: (1) use cognitive task analysis to describe final year nursing students situation awareness in recognising, responding and escalating care of deteriorating patients in ward settings; and (2) make recommendations for training and practice. DESIGN: A mixed methods cognitive task analysis with a convergent triangulation design. METHOD: Data collection involved observations of 33 final year nursing students in simulated deteriorating patient scenarios and retrospective cognitive interviews. A process tracing technique was applied to identify the cues to deterioration participants perceived; how cue perception altered as situational demands increased; the extent that participants made connections between perceived cues and reached a situational understanding; and the factors that influenced and constrained participants situation awareness. Qualitative and quantitative findings are woven together and presented using descriptive statistics, illustrative quotations and timeline extractions. RESULTS: The median cue perception was 65.4% and 57.6% in the medical and surgical scenarios, respectively. Perception was negatively influenced by incomplete vital sign monitoring as situations escalated; limited physical assessments; passive scanning behaviours; poor task automaticity; and excessive cognitive demands. Incomplete perception, poor cue integration and underdeveloped mental models influenced situational understanding. Escalation calls did not always accurately reflect situations and a reporting mindset was evident. Clinical exposure to deteriorating patients was described as variable and opportunistic. REPORTING METHOD: The study is reported in accordance with the Good Reporting of a Mixed Methods Study (GRAMMS) checklist. PATIENT OR PUBLIC CONTRIBUTION: Patients and public were not involved in this research.

NaHCO3 loading causes increased arterial pressure and kidney damage in rats with chronic kidney disease.

Sodium bicarbonate (NaHCO3) is commonly utilized as a therapeutic to treat metabolic acidosis in people with chronic kidney disease (CKD). While increased dietary sodium chloride (NaCl) is known to promote volume retention and increase blood pressure, the effects of NaHCO3 loading on blood pressure and volume retention in CKD remain unclear. In the present study, we compared the effects of NaCl and NaHCO3 loading on volume retention, blood pressure, and kidney injury in both 2/3 and 5/6 nephrectomy remnant kidney rats, a well-established rodent model of CKD. We tested the hypothesis that NaCl loading promotes greater volume retention and increases in blood pressure than equimolar NaHCO3. Blood pressure was measured 24 h daily using radio telemetry. NaCl and NaHCO3 were administered in drinking water ad libitum or infused via indwelling catheters. Rats were housed in metabolic cages to determine volume retention. Our data indicate that both NaHCO3 and NaCl promote hypertension and volume retention in remnant kidney rats, with salt-sensitivity increasing with greater renal mass reduction. Importantly, while NaHCO3 intake was less pro-hypertensive than equimolar NaCl intake, NaHCO3 was not benign. NaHCO3 loading significantly elevated blood pressure and promoted volume retention in rats with CKD when compared with control rats receiving tap water. Our findings provide important insight into the effects of sodium loading with NaHCO3 in CKD and indicate that NaHCO3 loading in patients with CKD is unlikely to be benign.

Identifying Factors that Support the Delivery of Exceptional Care in General Practice and Development of the IDEAL Framework: A Qualitative Study.

The positive deviance approach seeks to identify and learn from those that perform exceptionally well. Positive deviance as an approach to quality improvement is gaining traction in general practice. This study aimed to explore and compare stakeholders' perceptions of the factors that support the delivery of exceptional care in general practice and to refine a previously developed theoretical framework of factors associated with positively deviant care in general practice: the Identifying and Disseminating the Exceptional to Achieve Learning (IDEAL) framework. Semi-structured interviews were conducted with 33 purposively sampled patients, general practitioners, practice nurses, and practice managers in Irish general practice. Subsequently, a directed content analysis approach was employed to deductively analyse interview data using the IDEAL framework, and newly emerging factors were inductively analysed and abstracted into the framework. Several distinct strategies (e.g. patient activation and team collaboration), structures (e.g. facilities and staffing), and contextual factors (e.g. communication and rapport, and culture) were found to support the delivery of exceptional care, and differences in perceptions, values, and expectations emerged between patients and practice staff. Interview data largely supported the pre-determined factors posited by the IDEAL framework, and new factors were abstracted into the framework (e.g. facilities and infrastructure). Stakeholder engagement regarding the factors supporting exceptional care in general practice supported and extended the IDEAL framework, contributing to a more comprehensive understanding of how exceptional care is delivered in general practice. The refined framework will support researchers, policymakers, and teams looking to support, measure, and achieve exceptionally good patient care in general practice.

Exploring barriers and enablers to simulation-based training in emergency departments: an international qualitative study (BEST-ED Study).

INTRODUCTION: Simulation-based training (SBT) has gained significant traction within emergency medicine. The growing body of evidence describes the benefits that SBT can bring. However, identifying barriers and enablers when establishing successful SBT programmes in busy emergency departments (EDs), and ensuring longevity of such programmes, can be difficult. OBJECTIVE: We aim to identify barriers and enablers to SBT in busy EDs. METHODS: We explored and analysed the thoughts, experience and opinions of professionals involved in SBT and organisational support. 32 participants across 15 international sites were invited to a semistructured interview process. We included participants from a variety of backgrounds, from clinical staff to management staff. Transcribed interview data was classified and coded based on capability, opportunity and motivation behaviour (COM-B) domains and analysed based on theoretical domains framework. Frequency of the most mentioned thematic domain among participants is reported. RESULTS: The interview data revealed several common themes, including the following: knowledge and skills (90%), support and leadership (96%), mental barriers (87.5%), local culture (96.6%), dedicated space (65.2%), time constraints (46.8%), social influence (87.5%), education (90.6%), professional development (68.75%), exams (59.3%) and personal goals (93.75%). Management staff was observed to prioritise resource, staffing and flow, while the clinical cohort tended to focus on specialty and personal development when it came to simulation training in the ED. CONCLUSION: Potential barriers and enablers to SBT and in situ simulation for EDs were identified through interviews conducted in this study. The central themes in terms of barriers and enablers were local culture, leadership, individual needs, resources and optimisation. A tailored approach is vital for establishing a successful SBT and in situ simulation programme.

Extravasation of Blood and Blood Toxicity Drives Tubular Injury from RBC Trapping in Ischemic AKI.

Red blood cell (RBC) trapping is common in ischemic acute kidney injury (AKI) and presents as densely packed RBCs that accumulate within and engorge the kidney medullary circulation. In this study, we tested the hypothesis that "RBC trapping directly promotes tubular injury independent of extending ischemia time." Studies were performed on rats. Red blood cell congestion and tubular injury were compared between renal arterial clamping, venous clamping, and venous clamping of blood-free kidneys. Vessels were occluded for either 15 or 45 min with and without reperfusion. We found that RBC trapping in the medullary capillaries occurred rapidly following reperfusion from renal arterial clamping and that this was associated with extravasation of blood from congested vessels, uptake of blood proteins by the tubules, and marked tubular injury. To determine if this injury was due to blood toxicity or an extension of ischemia time, we compared renal venous and arterial clamping without reperfusion. Venous clamping resulted in RBC trapping and marked tubular injury within 45 min of ischemia. Conversely, despite the same ischemia time, RBC trapping and tubular injury were minimal following arterial clamping without reperfusion. Confirming the role of blood toward tubular injury, injury was markedly reduced in blood-free kidneys with venous clamping. Our data demonstrate that RBC trapping results in the rapid extravasation and uptake of blood components by tubular cells, causing toxic tubular injury. Tubular toxicity from extravasation of blood following RBC trapping appears to be a major component of tubular injury in ischemic AKI, which has not previously been recognized.

Aldosterone Antagonism Is More Effective at Reducing Blood Pressure and Excessive Renal ENaC Activity in AngII-Infused Female Rats Than in Males.

BACKGROUND: AngII (angiotensin II)-dependent hypertension causes comparable elevations of blood pressure (BP), aldosterone levels, and renal ENaC (epithelial Na+ channel) activity in male and female rodents. Mineralocorticoid receptor (MR) antagonism has a limited antihypertensive effect associated with insufficient suppression of renal ENaC in male rodents with AngII-hypertension. While MR blockade effectively reduces BP in female mice with salt-sensitive and leptin-induced hypertension, MR antagonism has not been studied in female rodents with AngII-hypertension. We hypothesize that overstimulation of renal MR signaling drives redundant ENaC-mediated Na+ reabsorption and BP increase in female rats with AngII-hypertension. METHODS: We employ a combination of physiological, pharmacological, biochemical, and biophysical approaches to compare the effect of MR inhibitors on BP and ENaC activity in AngII-infused male and female Sprague Dawley rats. RESULTS: MR blockade markedly attenuates AngII-hypertension in female rats but has only a marginal effect in males. Spironolactone increases urinary sodium excretion and urinary sodium-to-potassium ratio in AngII-infused female, but not male, rats. The expression of renal MR and HSD11ß2 (11ß-hydroxysteroid dehydrogenase type 2) that determines the availability of MR to aldosterone is significantly higher in AngII-infused female rats than in males. ENaC activity is ≈2× lower in spironolactone-treated AngII-infused female rats than in males. Reduced ENaC activity in AngII-infused female rats on spironolactone correlates with increased interaction with ubiquitin ligase Nedd4-2 (neural precursor cell expressed developmentally down-regulated protein 4-2), targeting ENaC for degradation. CONCLUSIONS: MR-ENaC axis is the primary determinant of excessive renal sodium reabsorption and an attractive antihypertensive target in female rats with AngII-hypertension, but not in males.

An assessment of the simulated performance of basic clinical procedures by junior doctors during the first year of clinical practice.

BACKGROUND: Upon entering the healthcare system, junior doctors may lack the skills required to care for patients, and feel unprepared for their role, with considerable variation in the level of proficiency in the performance of particular clinical procedures. OBJECTIVE: To compare the performance and proficiency (self-report and observed) of the performance of nine basic clinical procedures. METHODS: Seventeen interns were observed performing nine clinical procedures in a simulated setting in June 2021 (Assessment 1) and January 2022 (Assessment 2). The observers identified whether each step in the procedure was performed correctly, and provided an overall assessment of proficiency. The participants also rated their own level proficiency. RESULTS: At Assessment 1 the number of steps performed correctly ranged from a mean of 41.9-83.5%. At Assessment 2 the number of steps performed correctly ranged from a mean of 41.9-97.8%. The most common median proficiency rating for Assessment 1 was 'close supervision', and was 'indirect supervision' at Assessment 2. There was a significant and large effect size in the improvement in performance from Assessment 1 to Assessment 2. Low correlations were found between observer and self-reported proficiency in performance of the procedures. CONCLUSIONS: The large improvement in performance across the two assessments is encouraging. However, there is a need to address the variability in performance on graduation from medical school, and to ensure that any assessment of proficiency is not only reliant on self-report.

Measuring and monitoring patient safety in hospitals in the Republic of Ireland.

BACKGROUND: Measuring and monitoring safety (MMS) is critical to the success of safety improvement efforts in healthcare. However, a major challenge to improving safety is the lack of high quality information to support performance evaluation. AIMS: The aim of this study was to use Vincent et al.'s MMS framework to evaluate the methods used to MMS in Irish hospitals and make recommendations for improvement. METHODS: The first phase of this qualitative study used document analysis to review national guidance on MMS in Ireland. The second phase consisted of semi-structured interviews with key stakeholders on their understanding of MMS. The MMS framework was used to classify the methods identified. RESULTS: Six documents were included for analysis, and 24 semi-structured interviews were conducted with key stakeholders working in the Irish healthcare system. A total of 162 methods of MMS were identified, with one method of MMS addressing two dimensions. Of these MMS methods, 30 (18.4%) were concerned with past harm, 40 (24.5%) were concerned with the reliability of safety critical processes, 16 (9.8%) were concerned with sensitivity to operations, 28 (17.2%) were concerned with anticipation and preparedness, and 49 (30%) were concerned with integration and learning. CONCLUSIONS: There are a wide range of methods of MMS in Irish hospitals. It is suggested that there is a need to identify those methods of MMS that are particularly useful in reducing harm and supporting action and improvement and do not place a large burden on healthcare staff to either use or interpret.

The impact of the COVID-19 pandemic on patient complaints within one Irish teaching hospital.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic dramatically impacted the delivery of hospital care in terms of quality and safety. OBJECTIVES: To examine complaints from two time points, quarter 4 (Q4) 2019 (pre-pandemic) and Q4 2020 (second wave), and explore whether there was a difference in the frequency and/or content of complaints. METHODS: A retrospective analysis of complaints from one Irish hospital was conducted using the Healthcare Complaints Analysis Tool (HCAT). Within each complaint, the content, severity, harm reported by the patient, and stage of care were categorised. The complaints were analysed using descriptive statistics and chi-square tests of independence. RESULTS: There were 146 complaints received in Q4 2019 and 114 in Q4 2020. Complaint severity was significantly higher in Q4 2019 as compared to Q4 2020. However, there were no other significant differences. Institutional processes (e.g. staffing, resources) were the most common reason for complaints (30% in Q4 2019 and 36% in Q4 2020). The majority of complaints were concerned with care on the ward (23% in Q4 2019 and 31% in Q4 2020). CONCLUSIONS: The severity of complaints was significantly higher in Q4 2019 than in Q4 2020, which requires further exploration as the reasons for this are unclear. The lack of a difference in the frequency and content of complaints during the two time periods was unexpected. However, this may be linked to a number of factors, including public support for the healthcare system, existing system-level issues in the hospital, or indeed increased staff collaboration in the context of the COVID-19 crisis.

A Mixed Methods Study Identifying the Competencies of Health Care Simulation Technicians.

INTRODUCTION: Health care simulation technicians (HSTs), also referred to as simulation operations specialists, are essential to the delivery of simulation-based education. The HST role draws on a broad range of knowledge, skills, and attitude competencies. However, because of the neoteric nature of the HST role and the ambiguity surrounding the core responsibilities of the position, it has proved difficult to identify the competencies required to perform this role successfully. This study aims to identify the knowledge, skills, and attitude competencies required by HSTs. METHODS: A mixed methods approach was used in this study. Data were collected from (1) online searches of HST job descriptions and (2) semistructured interviews about the competencies required by HSTs with 10 HSTs, 10 health care simulation educators, and 10 health care simulation center managers/director. The data from the job descriptions and interviews were analyzed using thematic analysis, using a framework method to guide the coding. RESULTS: A total of 59 competencies were identified from the job descriptions and 65 competencies from the interviews. This analysis resulted in the identification of 9 competency domains: 3 knowledge domains (technical, clinical, and pedagogic), 4 skills domains (resourcefulness, pedagogic, team, and technical), and 2 attitudes domains (professional and "can-do" mentality). CONCLUSIONS: The identification of the competencies required by HSTs will support the selection of candidates with the attributes that will allow them to be successful in this role and guide continuous professional development opportunities for current and future HSTs.

Brown-Norway chromosome 1 mitigates the upregulation of proinflammatory pathways in mTAL cells and subsequent age-related CKD in Dahl SS/JrHsdMcwi rats.

Chronic kidney disease (CKD) has a strong genetic component; however, the underlying pathways are not well understood. Dahl salt-sensitive (SS)/Jr rats spontaneously develop CKD with age and are used to investigate the genetic determinants of CKD. However, there are currently several genetically diverse Dahl SS rats maintained at various institutions and the extent to which some exhibit age-related CKD is unclear. We assessed glomerulosclerosis (GS) and tubulointerstitial fibrosis (TIF) in 3- and 6-mo-old male and female SS/JrHsdMcwi, BN/NHsd/Mcwi [Brown-Norway (BN)], and consomic SS-Chr 1BN/Mcwi (SS.BN1) rats, in which chromosome 1 from the BN rat was introgressed into the genome of the SS/JrHsdMcwi rat. Rats were fed a 0.4% NaCl diet. GS (31 ± 3% vs. 7 ± 1%) and TIF (2.3 ± 0.2 vs. 0.5 ± 0.1) were significantly greater in 6-mo-old compared with 3-mo-old SS/JrHsdMcwi rats, and CKD was exacerbated in males. GS was minimal in 6- and 3-mo-old BN (3.9 ± 0.6% vs. 1.2 ± 0.4%) and SS.BN1 (2.4 ± 0.5% vs. 1.0 ± 0.3%) rats, and neither exhibited TIF. In SS/JrHsdMcwi and SS.BN1 rats, mean arterial blood pressure was significantly greater in 6-mo-old compared with 3-mo-old SS/JrHsdMcwi (162 ± 4 vs. 131 ± 2 mmHg) but not SS.BN1 (115 ± 2 vs. 116 ± 1 mmHg) rats. In 6-mo-old SS/JrHsdMcwi rats, blood pressure was significantly greater in females. RNA-sequencing analysis revealed that inflammatory pathways were upregulated in isolated medullary thick ascending tubules in 7-wk-old SS/JrHsdMcwi rats, before the development of tubule pathology, compared with SS.BN1 rats. In summary, SS/JrHsdMcwi rats exhibit robust age-related progression of medullary thick ascending limb abnormalities, CKD, and hypertension, and gene(s) on chromosome 1 have a major pathogenic role in such changes.NEW & NOTEWORTHY This study shows that the robust age-related progression of kidney disease in Dahl SS/JrHsdMcw rats maintained on a normal-salt diet is abolished in consomic SS.BN1 rats. Evidence that medullary thick ascending limb segments of SS/JrHsdMcw rats are structurally abnormal and enriched in proinflammatory pathways before the development of protein casts provides new insights into the pathogenesis of kidney disease in this model.

A scoping review of patient safety research carried out in the Republic of Ireland.

Maintaining the highest levels of patient safety is a priority of healthcare organisations. However, although considerable resources are invested in improving safety, patients still suffer avoidable harm. The aims of this study are: (1) to examine the extent, range, and nature of patient safety research activities carried out in the Republic of Ireland (RoI); (2) make recommendations for future research; and (3) consider how these recommendations align with the Health Service Executive's (HSE) patient safety strategy. A five-stage scoping review methodology was used to synthesise the published research literature on patient safety carried out in the RoI: (1) identify the research question; (2) identify relevant studies; (3) study selection; (4) chart the data; and (5) collate, summarise, and report the results. Electronic searches were conducted across five electronic databases. A total of 31 papers met the inclusion criteria. Of the 24 papers concerned with measuring and monitoring safety, 12 (50%) assessed past harm, 4 (16.7%) the reliability of safety systems, 4 (16.7%) sensitivity to operations, 9 (37.5%) anticipation and preparedness, and 2 (8.3%) integration and learning. Of the six intervention papers, three (50%) were concerned with education and training, two (33.3%) with simplification and standardisation, and one (16.7%) with checklists. One paper was concerned with identifying potential safety interventions. There is a modest, but growing, body of patient safety research conducted in the RoI. It is hoped that this review will provide direction to researchers, healthcare practitioners, and health service managers, in how to build upon existing research in order to improve patient safety.

Hidden in Plain Sight: Does Medullary Red Blood Cell Congestion Provide the Explanation for Ischemic Acute Kidney Injury?

Acute kidney injury (AKI) represents a sudden reduction in renal function and is a major clinical problem with a high mortality rate. Despite decades of research, there are currently no direct therapies for AKI. The failure of therapeutic approaches identified in rodents to translate to human beings has led to questions regarding the appropriateness of these models. Our recent data indicate that there are two distinct processes driving tubular injury in the commonly used rat model of warm bilateral renal ischemia reperfusion injury, which often is used to mimic ischemic AKI. One results from the period of warm ischemia, manifesting as sublethal injury and coagulative necrosis of the proximal tubules in the renal cortex. This is the predominate type of injury observed 24 hours after reperfusion and the most well studied. The other results from red blood cell congestion of the outer medullary vasculature. This type of injury manifests as cell sloughing, along with the later formation of heme casts that fill distal nephron segments. Cell sloughing from congestion is most prominent in the early hours after reperfusion and often is masked by regeneration of the tubular epithelium by 24 hours postischemia. In this review, we argue that injury from outer medullary red blood cell congestion reflects the pathology observed in human kidneys and likely is representative of injury in most cases of ischemic AKI after shock. Greater focus on this congestive injury is likely to lead to improved translation in AKI.
