Psychotropic Medication Usage in Pediatric CKD: Reporting from the Chronic Kidney Disease in Children Cohort.

Mental health disorders (MHD) within the pediatric chronic kidney disease (CKD) population are prevalent. The frequency is unknown with which psychotropic medications that commonly treat these conditions are used in this population. Data from the Chronic Kidney Disease in Children (CKiD) cohort study were utilized to describe the use of psychotropic medications and patient-related characteristics of use. Medications were classified into 3 groups: antidepressants, CNS stimulants, and antipsychotic/mood stabilizing medications. Participant age, sex, CKD severity, and duration of medication use were ascertained. Medication use was evaluated in parallel with CKD disease type, presence of urological comorbidity, and hypertension. Chi-square tests compared subgroup medication use. Among 1074 CKiD participants (median baseline age 9.8 years), 6% (n=60) of participants used psychotropic medications at study entry with 11% reporting incident use of any medication category (n=120). CNS stimulants were most common at baseline. Antidepressants were more frequent among incident users at 7%. Use of two or more medications was rare (3%). Median eGFR at medication initiation was 45 ml/min|1.73m2. CNS stimulants were reported at a higher rate in males compared to females (p<0.05). 11% of CKiD patients report incident use of any psychotropic medication, with 7% reporting incident use of antidepressants. Future work is warranted to better ascertain the frequency, safety, and efficacy of psychotropic medication usage in relationship to formal MHD diagnoses in the pediatric CKD population.

Romosozumab rescues impaired bone mass and strength in a murine model of diabetic kidney disease

As international incidence of diabetes and diabetes-driven comorbidities such as chronic kidney disease (CKD) continue to climb, interventions are needed that address the high-risk skeletal fragility of what is a complex disease state. Romosozumab (Romo) is an FDA-approved sclerostin inhibitor that has been shown to increase bone mineral density and decrease fracture rates in osteoporotic patients with mild to severe CKD, but its effect on diabetes-weakened bone is unknown. We aimed to test Romo's performance in a model of combined diabetes and CKD. 6-week old male C57BL/6 mice were randomly divided into control (CON) and disease model (STZ-Ad) groups, using a previously established streptozotocin- and adenine-diet-induced model. After 16 weeks of disease induction, both CON and STZ-Ad groups were subdivided into two treatment groups and given weekly subcutaneous injections of 100 μL vehicle (phosphorus buffered saline, PBS) or 10 mg/kg Romo. Mice were euthanized after 4 weeks of treatment via cardiac exsanguination and cervical dislocation. Hindlimb bones and L4 vertebrae were cleaned of soft tissue, wrapped in PBS-soaked gauze and stored at 20C. Right tibiae, femora, and L4s were scanned via microcomputed tomography; tibiae were then tested to failure in 4-pt bending while L4s were compression tested. Romo treatment significantly increased cortical and trabecular bone mass in both STZ-Ad and CON animals. These morphological improvements created corresponding increases in cortical bending strength and trabecular compression strength, with STZ-Ad treated mice surpassing vehicle CON mice in all trabecular mechanics measures. These results suggest that Romo retains its efficacy at increasing bone mass and strength in diabetic kidney disease.

Development and validation of a race-agnostic computable phenotype for kidney health in adult hospitalized patients.

Standard race adjustments for estimating glomerular filtration rate (GFR) and reference creatinine can yield a lower acute kidney injury (AKI) and chronic kidney disease (CKD) prevalence among African American patients than non-race adjusted estimates. We developed two race-agnostic computable phenotypes that assess kidney health among 139,152 subjects admitted to the University of Florida Health between 1/2012-8/2019 by removing the race modifier from the estimated GFR and estimated creatinine formula used by the race-adjusted algorithm (race-agnostic algorithm 1) and by utilizing 2021 CKD-EPI refit without race formula (race-agnostic algorithm 2) for calculations of the estimated GFR and estimated creatinine. We compared results using these algorithms to the race-adjusted algorithm in African American patients. Using clinical adjudication, we validated race-agnostic computable phenotypes developed for preadmission CKD and AKI presence on 300 cases. Race adjustment reclassified 2,113 (8%) to no CKD and 7,901 (29%) to a less severe CKD stage compared to race-agnostic algorithm 1 and reclassified 1,208 (5%) to no CKD and 4,606 (18%) to a less severe CKD stage compared to race-agnostic algorithm 2. Of 12,451 AKI encounters based on race-agnostic algorithm 1, race adjustment reclassified 591 to No AKI and 305 to a less severe AKI stage. Of 12,251 AKI encounters based on race-agnostic algorithm 2, race adjustment reclassified 382 to No AKI and 196 (1.6%) to a less severe AKI stage. The phenotyping algorithm based on refit without race formula performed well in identifying patients with CKD and AKI with a sensitivity of 100% (95% confidence interval [CI] 97%-100%) and 99% (95% CI 97%-100%) and a specificity of 88% (95% CI 82%-93%) and 98% (95% CI 93%-100%), respectively. Race-agnostic algorithms identified substantial proportions of additional patients with CKD and AKI compared to race-adjusted algorithm in African American patients. The phenotyping algorithm is promising in identifying patients with kidney disease and improving clinical decision-making.

Various Patterns of the Derangement of Liver Function Tests in End-Stage Renal Disease Patients on Maintenance Hemodialysis-A Single Centered Study from Pakistan

Background: Chronic kidney disease (CKD) patients on maintenance hemodialysis often present with various comorbidities, among which liver dysfunction is not uncommon. The prevalence of hepatitis B and C among this population suggests a multifaceted interaction between liver health and renal impairment. Studies have indicated that serum aminotransferase levels are inversely related to the severity of CKD and may be affected by hemodialysis. Objective: This study aimed to delineate the patterns and etiologies of liver function test derangements in an end-stage renal disease (ESRD) cohort on maintenance hemodialysis, assessing the association between dialysis duration and liver enzyme levels. Methods: In this cross-sectional observational study, 91 ESRD patients undergoing hemodialysis at a single center were evaluated. Liver function patterns were classified as hepatocellular, cholestatic, or mixed based on serum levels of aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (ALKP), and gamma-glutamyl transferase (GGT). Statistical analysis was performed using SPSS version 25, with a significant p-value set at ≤ 0.05. Results: The average age of patients was 44 ± 15 years. The majority had been on dialysis for one (41.8%) or two years (33%). Hepatitis C (20.9%) was the predominant cause of viral hepatitis, followed by Hepatitis B (13.2%). Sepsis was identified as a major contributor to liver enzyme derangement (58.2%). The most common pattern of deranged liver enzymes was mixed (49.5%), followed by cholestatic (27.5%) and hepatocellular (23%). Elevated transaminases were noted, with AST at 227.8 ± 264.1 IU/mL and ALT at 237.1 ± 281.8 IU/mL. Conclusion: In the studied ESRD population, sepsis was the leading cause of liver dysfunction, with a higher incidence of mixed liver enzyme pattern derangements. The elevated aminotransferase levels contrast with previous studies, suggesting the need for enhanced infection control and consistent monitoring of liver health in the hemodialysis setting.

Does donor age have effects on senescence biomarkers in kidney-transplanted patients?

Renal transplantation is an effective treatment for severe chronic kidney diseases. However, young patients often face a scarcity of kidneys from donors of similar age, resulting in the transplantation of older organs which increase the risk of graft rejection and several complications compared to older individuals who receive kidneys from donors of similar age or younger. This paper focuses on studying different senescence biomarkers in donors and patients who received kidneys from various age ranges complying with the STROBE requirements. We studied 61 patients subjected to renal transplant isolating blood samples 24h before, and 24h, 3d, 7d, 3m and 6m after transplant. The patients were divided into three groups: older donor than the patient (Old Donor), younger donor than the patient (Young Donor), and similar age (Matched). We studied different senescence markers such as p16, p21, IL-6 and SASP release. Young patients who receive older organs showed increased mRNA and protein expression of the senescence makers. Hence, increased SASP release was also observed in patients from older donor. On the other hand, older patients who receive younger organs showed a slow but consistent improvement in their initial senescent phenotype. Additionally, macrophage cell model treated with blood-derived serum from patients six months after the transplant showed a pro-senescence environment in macrophages proposed by the SASP from the patients. These results lead the hypothesis that senolytics could reduce the presence of senescent cells and mitigate the complications associated with the transplantation of older organs in young patients.

Moderate and Severe Chronic Kidney Disease Predict Greater 5-Year Mortality following Major Lower-Extremity Amputation

Severe Chronic Kidney Disease (CKD) predicts greater mortality after major lower extremity amputation (LEA), but it remains poorly understood whether patients with earlier stages of CKD share similar risk. We assessed long-term postoperative outcomes for patients with CKD in a retrospective chart review of 565 patients who underwent atraumatic major LEA at a large tertiary referral center from 2015 to 2021. We stratified patients by renal function and compared outcomes including survival. Preoperative CKD diagnosis was related to many patient characteristics, co-occurred with many comorbidities, and was associated with less follow-up and survival. Kaplan-Meier and Cox Regression analyses showed significantly worse 5-year survival for major LEA patients with mild, moderate, or severe CKD compared to major LEA patients with no history of CKD at the time of amputation (P < 0.001). Severe CKD independently predicted worse mortality at 1-year (odds ratio [OR] 2.91; P = 0.003) and 5-years (OR 3.08; P < 0.001). Moderate CKD independently predicted worse 5-year mortality (OR 2.66; P = 0.029). This study demonstrates that moderate and severe CKD predict greater long-term mortality following major LEA when controlling for numerous potential confounders. This finding raises questions about the underlying mechanism if causal and highlights an opportunity to improve outcomes with earlier recognition and optimization CKD preoperatively.

The Role of Comorbidities in Predicting Functional Improvement After Transcatheter Aortic Valve Implantation

Patients undergoing transcatheter aortic valve implantation (TAVI) have a high comorbidity burden. We sought to stratify patients into functional outcomes using the Kansas City Cardiomyopathy Questionnaire (KCCQ-12), a patient-reported outcome with benefits over both the New York Heart Association (NYHA) classification and the original 23-item KCCQ, and to evaluate the importance of comorbidities in predicting failure of functional improvement post-TAVI in a contemporary cohort. In total, 366 patients with severe aortic stenosis undergoing TAVI with baseline KCCQ-12 were retrospectively analysed and divided into two groups. Failure to improve was defined as a score <60 and a change in score <10 at 1 year in either overall score (KCCQ-OS) or clinical summary score (KCCQ-CSS). Failure to improve was noted in 13% of patients, who were more likely to have lower KCCQ-OS at baseline (47 [35-59] vs 56 [42-74]), chronic obstructive pulmonary disease (COPD) (19% vs 8%), severe chronic kidney disease (CKD) (13% vs 2%), a clinical frailty score (CFS) ≥5 (41% vs 14%), and lower serum albumin (36 g/L [34-38] vs 38 g/L [35-40]). On multivariate analysis, with an area under the curve of 0.71 (0.63-0.78), baseline KCCQ-OS (adjusted odds ratio [aOR] 0.3 [0.1-0.6], p=0.04), COPD (aOR 2.8 [1.2-6.5], p=0.02), and severe CKD (aOR 5.7 [1.7-18.5], p=0.004) remained independent predictors. CFS alone had a similar predictive value as the multivariable model (OR 2.0 [1.3-3.4], area under the curve 0.69 [0.59-0.80], p<0.001). KCCQ scores were effective in delineating functional outcomes, with most patients in our relatively lower surgical risk cohort showing significant functional improvements post-TAVI. Low baseline KCCQ, moderate or worse COPD, and severe CKD were associated with failure of improvement post-TAVI. Baseline CFS appears to be a good screening tool to predict poor improvement. These factors should be evaluated and weighted accordingly in pre-TAVI assessments and decision-making.

Real-world evidence of constipation and laxative use in the Korean population with chronic kidney disease from a common data model

Constipation is a highly prevalent gastrointestinal disorder in patients with chronic kidney disease (CKD). However, our understanding of its epidemiology and management in CKD is limited. We aimed to explore real-world data on constipation and laxative use in patients with CKD in a nationwide population-based cohort from the Korean Health Insurance Review and Assessment-National Patient Sample database. This study analyzed retrospective health claims data in Korea from 2012 to 2017 that were transformed into the Observational Medical Outcomes Partnership Common Data Model. The pooled proportion of constipation diagnoses was 30.5% in all patients with CKD and 15.9%, 16.5%, 17.4%, 29.9%, and 43.3% in patients with CKD stages 1–5, respectively, suggesting a higher prevalence in advanced CKD. Patients receiving peritoneal dialysis or hemodialysis had the highest prevalence of constipation, while transplant recipients showed a prevalence comparable to that of patients with early CKD. Patients with CKD had a significantly higher risk of constipation than age- and sex-matched non-CKD individuals (range of odds ratio [OR]:1.66–1.90). Laxative prescribing patterns differed by CKD severity. Osmotic agents were prescribed in more than half of patients with advanced CKD, while magnesium salts and bulking agents were prescribed less frequently. The CKD patients with constipation were more likely to be prescribed constipation-inducing medications, including antipsychotic and neurological medications. Our findings provide real-world constipation and laxative prescription status in the Korean CKD population, revealing a significantly higher risk of constipation and different laxative prescribing patterns in patients with CKD.

ASSESSMENT OF COMPLETE BLOOD COUNT AND LIVER ENZYMES IN CHRONIC KIDNEY DISEASE PATIENT

Chronic renal failure (CRF) poses a significant global health challenge, with chronic kidney disease (CKD) characterised by kidney damage or a glomerular filtration rate (GFR) persistently below 60 ml/min for over three months. This observational study, conducted in Faisalabad from January to July 2023, aimed to evaluate haematological variables and liver enzymes across different stages of CKD. Using non-probability purposive sampling, 144 CKD patient files and 48 healthy control files were collected, excluding specific conditions. CKD staging was determined using the Modification of Diet in Renal Disease (MDRD) algorithm, categorizing patients into mild (Group A), moderate (Group B), severe (Group C) CKD, and controls (Group D). Data analysis was performed using SPSS v23. Mean ± SD values were presented for each parameter across the four groups. Haemoglobin levels (Hb g/dl) exhibited a decreasing trend in CKD patients compared to the control group, with values of 13.7 ± 1.50 in controls, 11.7 ± 0.64 in Group 1, 9.7 ± 0.57 in Group 2, and 6.7 ± 1.5 in Group 3. Red blood cell count (RBCs per million/mm3) also decreased progressively in CKD patients compared to controls, with values of 5.48 ± 0.59, 4.62 ± 0.15, 3.57 ± 0.28, and 2.81 ± 0.23 in the respective groups. Conversely, white blood cell counts (WBC thousand/mm3) increased with CKD progression, showing values of 8406 ± 1383 in controls, 10674 ± 1006 in Group 1, 12028 ± 643.5 in Group 2, and 13564 ± 741.29 in Group 3. Similarly, platelet counts (lakh/ul) exhibited a decreasing trend in CKD patients compared to controls, with values of 324708 ± 112970, 235458 ± 63853, 144979 ± 6935.8, and 126333 ± 4768.3, respectively. Analysis of liver enzymes revealed a progressive decrease in aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels as CKD advanced. AST levels (U/L) decreased from 29.104 ± 3.130 in controls to 7.5825 ± 1.543 in Group 3, while ALT levels (U/L) decreased from 48.145 ± 4.9679 in controls to 12.270 ± 3.3500 in Group 3. Our findings demonstrate that haemoglobin, red blood cell count, platelet count, and liver enzyme levels (AST and ALT) decrease as CKD progresses while white blood cell count increases. These insights into haematological and hepatic biomarkers underscore the dynamic nature of CKD pathology and may inform clinical management strategies.

Cost-effectiveness of sodium zirconium cyclosilicate for advanced chronic kidney patients in Singapore.

Hyperkalaemia (HK) is prevalent among patients with chronic kidney disease (CKD) and chronic heart failure, especially if they are treated with renin-angiotensin-aldosterone system inhibitors (RAASi). This study evaluated the cost-effectiveness of a newly developed anti-HK therapy, sodium zirconium cyclosilicate (SZC), to the current standard of care for treating HK in advanced CKD patients from the Singapore health system perspective. We adapted a global microsimulation model to simulate individual patients' potassium level trajectories with baseline potassium ≥5.5 mmol/L, CKD progression, changes in treatment, and other fatal and non-fatal events. Effectiveness data was derived from ZS-004 and ZS-005 trials. Model parameters were localised using CKD patients' administrative and medical records at the Singapore General Hospital Department of Renal Medicine. We estimated the lifetime cost and quality-adjusted life years (QALYs) of each HK treatment, and the incremental cost-effectiveness ratio of SZC. SZC demonstrated cost-effectiveness with an incremental cost-effectiveness ratsio of SGD 45 068 per QALY over a lifetime horizon, below the willingness-to-pay threshold of SGD 90 000 per QALY. Notably, SZC proved most cost-effective for patients with less severe CKD who were concurrently using RAASi. Sensitivity analyses confirmed the robustness of the findings, accounting for alternative parameter values and statistical uncertainty. This study establishes the cost-effectiveness of SZC as a treatment for HK, highlighting its potential to mitigate the risk of hyperkalaemia and optimise RAASi therapy. These findings emphasise the value of integrating SZC into the Singapore health system for improved patient outcomes and resource allocation.

Hospital complications in patients with acute kidney injury after coronary artery bypass grafting

The aim was to assess the incidence of hospital complications in patients with acute kidney injury (AKI) after coronary artery bypass grafting (CABG).Patients and Methods. The study included 77 patients with stable angina who underwent CABG, aged 65 (61-69) years, 77,9 % men. The number of patients with arterial hypertension was 96,1 %, with carbohydrate metabolism disorders 45,5 %, with chronic kidney disease (CKD) 22,1 %, and with myocardial infarction (MI) 57,1 %. CABG on the working heart was performed in 28,6 %, bimammary CABG in 49,4 %. The duration of artificial circulation was 64 (55-82) minutes; the number of shunts implanted was 2,7+0,7 units. CKD was diagnosed when the glomerular filtration rate was less than 60 ml/min. The development of AKI was assessed according to the KDIGO criteria (2012).Results. CABG related AKI was detected in 10 (13 %) patients, of which grade 1 in 9 (11,7 %), grade 2 in 1 (1,3 %). The indicators associated with AKI after CABG were more severe initial CKD (stages 3b and 4 CKD – 20 % vs 1,5 %, p=0,043), a higher incidence of acute heart failure (in terms of adrenaline requirement – 30 % vs 5,9 %, p=0,043), more occluded coronary arteries (in the groups with and without CABG: one occlusion 70 % and 52,2 %, two occlusions 0 % and 13,4 %, three occlusions 10 % and 0 %, respectively, p=0,028). More severe CKD (stages 3b and 4) statistically significantly increased the relative risk of AKI after CABG by an average of 2,9 times. Among patients with AKI compared to patients without AKI after CABG, there was a higher incidence of cardiac death (20 % vs 0 %, p=0,015), intraoperative MI (60 % vs 8,9 %, p=0,001), acute heart failure (30 % vs 5,9 %, p=0,043).Conclusion. The incidence of AKI following CABG was 13 %. The development of AKI was associated with more severe initial CKD. Patients with postoperative AKI had a poor hospital prognosis.

Multiplexed PLGA scaffolds with nitric oxide-releasing zinc oxide and melatonin-modulated extracellular vesicles for severe chronic kidney disease

IntroductionWith prevalence of chronic kidney disease (CKD) in worldwide, the strategies to recover renal function via tissue regeneration could provide alternatives to kidney replacement therapies. However, due to relatively low reproducibility of renal basal cells and limited bioactivities of implanted biomaterials along with the high probability of substance-inducible inflammation and immunogenicity, kidney tissue regeneration could be challenging. ObjectivesTo exclude various side effects from cell transplantations, in this study, we have induced extracellular vesicles (EVs) incorporated cell-free hybrid PMEZ scaffolds. MethodsHybrid PMEZ scaffolds incorporating essential bioactive components, such as ricinoleic acid grafted Mg(OH)2 (M), extracellular matrix (E), and alpha lipoic acid-conjugated ZnO (Z) based on biodegradable porous PLGA (P) platform was successfully manufactured. Consecutively, for functional improvements, melatonin-modulated extracellular vesicles (mEVs), derived from the human umbilical cord MSCs in chemically defined media without serum impurities, were also loaded onto PMEZ scaffolds to construct the multiplexed PMEZ/mEV scaffold. ResultsWith functionalities of Mg(OH)2 and extracellular matrix-loaded PLGA scaffolds, the continuous nitric oxide-releasing property of modified ZnO and remarkably upregulated regenerative functionalities of mEVs showed significantly enhanced kidney regenerative activities. Based on these, the structural and functional restoration has been practically achieved in 5/6 nephrectomy mouse models that mimicked severe human CKD. ConclusionOur study has proved the combinatory bioactivities of the biodegradable PLGA-based multiplexed scaffold for kidney tissue regeneration in 5/6 nephrectomy mouse representing a severe CKD model. The optimal microenvironments for the morphogenetic formations of renal tissues and functional restorations have successfully achieved the combinatory bioactivities of remarkable components for PMEZ/mEV, which could be a promising therapeutic alternative for CKD treatment.

Prevalence, patterns, and impacts of multimorbidity on adverse clinical outcomes in chronic kidney disease: A systematic review

Background: Multimorbidity is the concurrent presence of two or more long-term health conditions in the same individual. It fragments healthcare delivery and affects quality of life. Chronic kidney disease (CKD) often occurs with multimorbidity. The prevalence of CKD is rising; however, there is a lack of evidence on the prevalence, patterns, and impacts of multimorbidity on adverse clinical outcomes in patients with CKD.&#x0D; Methods: This was a systematically conducted literature review. A search was conducted in EMBASE, MEDLINE, CINAHL, and SCOPUS (2019-2023). The main search terms were “chronic kidney disease” and “multimorbidity.” The eligibility criteria were observational studies with adult participants with all stages of CKD (CKD stages 1-5, including those on renal replacement therapy). The exposure was multimorbidity quantified by measures. All-cause mortality, kidney disease progression, hospitalisation, and cardiovascular events were outcomes. The Joanna Briggs Institute (JBI) checklist was used for the risk of bias assessment. Due to heterogeneity in design and methods, Jennie Popay’s narrative synthesis was used for data synthesis.&#x0D; Results: Of 6879 papers, nine papers met the inclusion criteria. Most studies included participants with all stages of CKD (CKD stage 1-5). The prevalence of multimorbidity ranged from 86.6% to 99.1%. Hypertension was the most prevalent comorbidity. The combination of concordant multimorbidity (hypertension, diabetes, and cardiovascular diseases) was highly prevalent. Multimorbidity was significantly associated with mortality, cardiovascular events, kidney disease progression, and hospitalisation. While older people had more multimorbidity burdens, younger patients with CKD were at a higher risk of death from multimorbidity. Severe CKD with clusters of cardiovascular diseases, diabetes, chronic pain, and depression was significantly associated with all-cause mortality.&#x0D; Conclusion: There are associations between multimorbidity and adverse clinical outcomes in patients with CKD. However, there is a lack of data on Black, Asian, and Minority Ethnic participants from low- and middle-income countries. Further research is needed to investigate the high prevalence of chronic pain and depression in chronic kidney disease.

Clinical characteristics and long-term outcomes of patients with heart failure with improved ejection fraction. First Polish experience from LECRA-HF registry

PurposeHeart failure (HF) with improved ejection fraction (HFimpEF) is a new category of HF introduced in the newest European Society of Cardiology guidelines. However, clinical characteristics and long-term outcomes of HFimpEF patients remain insufficiently elucidated. We sought to characterize Polish HFimpEF patients and determine their long-term mortality. Material and methodsOf 1186 patients enrolled in the single-center Lesser Poland Cracovian Heart Failure (LECRA-HF) registry between 2009 and 2019 and hospitalized due to HF decompensation, 340 (28.7%) were those with HF with reduced ejection fraction (HFrEF). Based on follow-up echocardiography, 61 (17.9%) of them were classified as HFimpEF and the remaining as HFnon-impEF. ResultsHFimpEF patients were more frequently females (P ​< ​0.001), had higher baseline left ventricular ejection fraction (LVEF, P ​< ​0.001), had less often a history of diabetes (P ​= ​0.024), severe chronic kidney disease (P ​= ​0.026) or prior myocardial infarction (P ​= ​0.008) than HFnon-impEF patients. By multivariable analysis the HFimpEF diagnosis was independently predicted by baseline NYHA I/II (odds ratio [OR] 2.347, 95% confidence interval [95%CI] 1.020–5.405), non-ischemic etiology (OR 3.096, 95%CI 1.587–6.024), lack of diabetes mellitus (OR 2.016, 95%CI 1.059–3.846) and higher baseline LVEF (OR 1.084, 95%CI 1.042–1.126, per 1%). Within the median 49 (25–77) months all-cause mortality was lower in HFimpEF than in HFnon-impEF (10.8 vs 16.4%/year, P ​= ​0.004). ConclusionsOur findings indicate that every sixth Polish patient with HFrEF has a chance to improve LVEF during follow-up and to become a HFimpEF patient. Baseline characteristics of HFimpEF patients are different from HFnon-impEF. Simultaneously, the HFimpEF diagnosis is associated with higher long-term survival.

Dietary Intake of Antioxidant Vitamins and Its Relation to the Progression of Chronic Kidney Disease in Adults With Preserved Renal Function

It is expected that antioxidants contribute to slow the progression of chronic kidney disease (CKD). However, there are no data on the protective effect of dietary antioxidant vitamins on CKD. The purpose of study was to evaluate the renoprotective effect of dietary antioxidant vitamins in the general population. The study participants were 127,081 Korean adults with preserved renal function with estimated glomerular filtration rate ≥60mL/min/1.73m2. They were categorized into 3 groups by tertile levels of dietary antioxidant vitamins intake including vitamins C, E, and A. Cox proportional hazard assumption was used to calculate multivariable hazard ratios and 95% confidence interval for the incident moderate to severe CKD (adjusted hazard ratio [95% confidence interval]) according to tertile levels of dietary intake of antioxidant vitamins. Subgroup analysis was conducted to evaluate the risk of progression from normal to mildly decreased renal function, and from mildly decreased renal function to moderate to severe CKD. The risk of moderate to severe CKD was not significantly associated with the third tertile of dietary antioxidant vitamin intake including vitamin C (1.02 [0.78-1.34]), E (0.96 [0.73-1.27]), and A (0.98 [0.74-1.29]). Additionally, any tertile groups didn't show the significant association with the risk of moderate to severe CKD. Subgroup analysis also didn't show the decreased risk of progression from normal to mildly decreased renal function, and from mildly decreased renal function to moderate to severe CKD in any tertile groups. Dietary intake of vitamins C, E, and A was not significantly associated with the risk of CKD progression.

The Impact of Age Over 80 Years on Outcomes in Geriatric Patients with Acute Pancreatitis: A Single Center Experience

The aim of this study is to evaluate the prognosis and mortality of acute pancreatitis (AP) in older subjects and compare octogenarians (≥80 years) with nonoctogenarians (age &amp;lt;80 years). The medical records of elderly patients who were followed up with the diagnosis of AP at our clinic between January 2018 and December 2021 were retrospectively analyzed. The etiology of AP, comorbidities, laboratory parameters, intensive care unit (ICU) admission, and mortality were noted. Among survivors, one-year mortality status was also recorded. Disease severity, in-hospital mortality and one-year mortality were compared. A total of 206 older patients (60 octogenarian, 146 nonoctogenariean) were recruited to the study. Of them, 115 (56%) were female and the mean age was 76.1±7.3 years. Severity of AP didn’t differ between octogenarians and nonctogenarians (p&amp;gt;0.05). ICU admission was seen in 13% of octogenarians and 11% of nonoctogenarians (p&amp;gt;0.05). In-hospital mortality occurred in 8.3% of octogenarians and 6.8% of nonoctogenarians (p&amp;gt;0.05). After discharge, one-year mortality occurred in 20% of octogenarians and 6.6% of nonoctogenarians (p&amp;lt;0.01). In multivariate analysis severe AP (OR:24.940;%95CI:1.013–95.609; p=0.01), ICU admission (OR:10.244;%95CI:1.399–74.990; p=0.01) and chronic kidney disease(CKD) (OR:9.840;%95CI:1.013–95.609; p=0.04) were independent risk factors for in-hospital mortality, and ≥80 years (OR:2.984;%95 CI:1.116–7.980; p =0.03) and neurological disorders (OR:4.424;%95CI:1.480–13.226; p &amp;lt;0.01) were independent factors related to one-year mortality. Our results showed that advenced age has not a significant effect on the course of AP in elderly. Comorbidities play important role in short- and long-term outcomes in elderly. Larger prospective trials are needed to draw more definitive conclusions.
