Abstract
BACKGROUND Sodium-glucose co-transporter-2 (SGLT2) inhibitors reduce progression of chronic kidney disease and the risk of cardiovascular morbidity and mortality in a wide range of patients. However, their effects on kidney disease progression in some patients with chronic kidney disease are unclear because few clinical kidney outcomes occurred among such patients in the completed trials. In particular, some guidelines stratify their level of recommendation about who should be treated with SGLT2 inhibitors based on diabetes status and albuminuria. We aimed to assess the effects of empagliflozin on progression of chronic kidney disease both overall and among specific types of participants in the EMPA-KIDNEY trial. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA), and included individuals aged 18 years or older with an estimated glomerular filtration rate (eGFR) of 20 to less than 45 mL/min per 1·73 m2, or with an eGFR of 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher. We explored the effects of 10 mg oral empagliflozin once daily versus placebo on the annualised rate of change in estimated glomerular filtration rate (eGFR slope), a tertiary outcome. We studied the acute slope (from randomisation to 2 months) and chronic slope (from 2 months onwards) separately, using shared parameter models to estimate the latter. Analyses were done in all randomly assigned participants by intention to treat. EMPA-KIDNEY is registered at ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and then followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroups of eGFR included 2282 (34·5%) participants with an eGFR of less than 30 mL/min per 1·73 m2, 2928 (44·3%) with an eGFR of 30 to less than 45 mL/min per 1·73 m2, and 1399 (21·2%) with an eGFR 45 mL/min per 1·73 m2 or higher. Prespecified subgroups of uACR included 1328 (20·1%) with a uACR of less than 30 mg/g, 1864 (28·2%) with a uACR of 30 to 300 mg/g, and 3417 (51·7%) with a uACR of more than 300 mg/g. Overall, allocation to empagliflozin caused an acute 2·12 mL/min per 1·73 m2 (95% CI 1·83-2·41) reduction in eGFR, equivalent to a 6% (5-6) dip in the first 2 months. After this, it halved the chronic slope from -2·75 to -1·37 mL/min per 1·73 m2 per year (relative difference 50%, 95% CI 42-58). The absolute and relative benefits of empagliflozin on the magnitude of the chronic slope varied significantly depending on diabetes status and baseline levels of eGFR and uACR. In particular, the absolute difference in chronic slopes was lower in patients with lower baseline uACR, but because this group progressed more slowly than those with higher uACR, this translated to a larger relative difference in chronic slopes in this group (86% [36-136] reduction in the chronic slope among those with baseline uACR <30 mg/g compared with a 29% [19-38] reduction for those with baseline uACR ≥2000 mg/g; ptrend<0·0001). INTERPRETATION Empagliflozin slowed the rate of progression of chronic kidney disease among all types of participant in the EMPA-KIDNEY trial, including those with little albuminuria. Albuminuria alone should not be used to determine whether to treat with an SGLT2 inhibitor. FUNDING Boehringer Ingelheim and Eli Lilly.

Impact of primary kidney disease on the effects of empagliflozin in patients with chronic kidney disease: secondary analyses of the EMPA-KIDNEY trial. Lancet Diabetes Endocrinol 2024; 12:51-60. [PMID: 38061372 DOI: 10.1016/s2213-8587(23)00322-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 10/24/2023] [Accepted: 10/25/2023] [Indexed: 12/23/2023]
Abstract
BACKGROUND The EMPA-KIDNEY trial showed that empagliflozin reduced the risk of the primary composite outcome of kidney disease progression or cardiovascular death in patients with chronic kidney disease mainly through slowing progression. We aimed to assess how effects of empagliflozin might differ by primary kidney disease across its broad population. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA). Patients were eligible if their estimated glomerular filtration rate (eGFR) was 20 to less than 45 mL/min per 1·73 m2, or 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher at screening. They were randomly assigned (1:1) to 10 mg oral empagliflozin once daily or matching placebo. Effects on kidney disease progression (defined as a sustained ≥40% eGFR decline from randomisation, end-stage kidney disease, a sustained eGFR below 10 mL/min per 1·73 m2, or death from kidney failure) were assessed using prespecified Cox models, and eGFR slope analyses used shared parameter models. Subgroup comparisons were performed by including relevant interaction terms in models. EMPA-KIDNEY is registered with ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroupings by primary kidney disease included 2057 (31·1%) participants with diabetic kidney disease, 1669 (25·3%) with glomerular disease, 1445 (21·9%) with hypertensive or renovascular disease, and 1438 (21·8%) with other or unknown causes. Kidney disease progression occurred in 384 (11·6%) of 3304 patients in the empagliflozin group and 504 (15·2%) of 3305 patients in the placebo group (hazard ratio 0·71 [95% CI 0·62-0·81]), with no evidence that the relative effect size varied significantly by primary kidney disease (pheterogeneity=0·62). The between-group difference in chronic eGFR slopes (ie, from 2 months to final follow-up) was 1·37 mL/min per 1·73 m2 per year (95% CI 1·16-1·59), representing a 50% (42-58) reduction in the rate of chronic eGFR decline. This relative effect of empagliflozin on chronic eGFR slope was similar in analyses by different primary kidney diseases, including in explorations by type of glomerular disease and diabetes (p values for heterogeneity all >0·1). INTERPRETATION In a broad range of patients with chronic kidney disease at risk of progression, including a wide range of non-diabetic causes of chronic kidney disease, empagliflozin reduced risk of kidney disease progression. Relative effect sizes were broadly similar irrespective of the cause of primary kidney disease, suggesting that SGLT2 inhibitors should be part of a standard of care to minimise risk of kidney failure in chronic kidney disease.

Abstract
Background Inborn errors of immunity (IEI) predispose patients to various infectious and non-infectious complications. Thanks to the development and expanding use of flow cytometry and increased awareness, the diagnostic rate of IEI has markedly increased in Algeria the last decade. Aim This study aimed to describe a large cohort of Algerian patients with probable IEI and to determine their clinical characteristics and outcomes. Methods We collected and analyzed retrospectively the demographic data, clinical manifestations, immunologic, genetic data, and outcome of Algerian IEI patients - diagnosed in the department of medical immunology of Beni Messous university hospital center, Algiers, from 2008 to 2021. Results Eight hundred and seven patients with IEI (482 males and 325 females) were enrolled, 9.7% of whom were adults. Consanguinity was reported in 50.3% of the cases and a positive family history in 32.34%. The medium age at disease onset was 8 months and at diagnosis was 36 months. The median delay in diagnosis was 16 months. Combined immunodeficiencies were the most frequent (33.8%), followed by antibody deficiencies (24.5%) and well-defined syndromes with immunodeficiency (24%). Among 287 patients tested for genetic disorders, 129 patients carried pathogenic mutations; 102 having biallelic variants mostly in a homozygous state (autosomal recessive disorders). The highest mortality rate was observed in patients with combined immunodeficiency (70.1%), especially in patients with severe combined immunodeficiency (SCID), Omenn syndrome, or Major Histocompatibility Complex (MHC) class II deficiency. Conclusion The spectrum of IEI in Algeria is similar to that seen in most countries of the Middle East and North Africa (MENA) region, notably regarding the frequency of autosomal recessive and/or combined immunodeficiencies.

Abstract
Introduction
The role of high-fidelity prosthetic simulation models for Botulinum Toxin Type A (BoNT-A) and cross-linked Hyaluronic Acid dermal fillers (HA) was evaluated and its efficacy and safety discussed in addition to its ethical and cost-effective advantages.
Method
The experiment group (N = 26) included a high-fidelity simulation silicone head to inject as part of dexterity training prior to injecting live adult voluntary models. The control group (N = 8) had only live adult voluntary models for the practical session. Pre-test and post-test of self- assessment of procedure competence and confidence to perform the procedure unaided was evaluated using a modified reflective CEX.
Results
The average competency and confidence pre-test for score for students was (mean±SD) 7.2±4.6 and 2.9±2.9 respectively. The post-test scores rose to 15.8± 2.5 and 7.8±1.5. The improved competency and confidence score were statistically significant (p < 0.05). There was no statistically significant difference of pre-test or post-test scores between the experimental and control group.
Conclusions
High fidelity synthetic simulation models allow novice practitioners to improve pre-procedure counselling, technical skills, management plan and follow up as well as confidence to perform the procedure effectively. We therefore recommend this method as a first-line training model in aesthetic medicine.

Abstract
Background:Smoking has been proposed to be associated with the development of anti-citrullinated peptide antibodies (ACPA) in rheumatoid arthritis (RA) patients.Objectives:To study the relationship between smoking and ACPA as well as smoking and RF in patients with RA in Kuwait Registry for Rheumatic Diseases (KRRD).Methods:Data on RA patients were extracted from KRRD from four major hospitals from February 2013 through December 2019. As females rarely smoke in Kuwait with a smoking prevalence of 3% in female RA patients in KRRD, females were excluded from the study population to reach the minimum statistical percentage needed to perform chi square test and assess the association between smoking and other variables. Statistical tests were applied where appropriate. Logistic regression was conducted to adjust for possible confounders including age, disease duration, comorbidities, family history of a rheumatic disease, ANA, treatment agents and disease activity and quality of life assessment tools.Results:A total of 863 RA male patients were studied with a mean age of 53.9±12.5 years and a mean disease duration 7.3±5.5 years. 652 (75.6%) had positive RF and 624 (72.3%) had positive ACPA. 431 (50%) had at least one comorbidity. 640 (74.2%) were on conventional disease modifying agents (cDMARD’s) and 223 (25.8%) were on biologic therapy. 183 (21.2%) were smokers. After adjustment of other factors, logistic regression showed that smokers were significantly different than non-smokers in terms of a positive ACPA (β=-1.051,p<0.001, odds=4.019) and a positive RF (β=-0.804,p=0.019, odds=2.517).Conclusion:Smokers have a higher risk of expressing a positive RF and a positive ACPA in a male population. Smoking should be considered as a possible risk factor for RA and efforts should be done to educate the population to cease smoking to possibly lower that risk.References:[1]Benowitz, N.L., 2009.

Abstract
Background:Missing data in clinical epidemiological researches violate the intention to treat principle,reduce statistical power and can induce bias if they are related to patient’s response to treatment. In multiple imputation (MI), covariates are included in the imputation equation to predict the values of missing data.Objectives:To find the best approach to estimate and impute the missing values in Kuwait Registry for Rheumatic Diseases (KRRD) patients data.Methods:A number of methods were implemented for dealing with missing data. These includedMultivariate imputation by chained equations(MICE),K-Nearest Neighbors(KNN),Bayesian Principal Component Analysis(BPCA),EM with Bootstrapping(Amelia II),Sequential Random Forest(MissForest) and mean imputation. Choosing the best imputation method wasjudged by the minimum scores ofRoot Mean Square Error(RMSE),Mean Absolute Error(MAE) andKolmogorov–Smirnov D test statistic(KS) between the imputed datapoints and the original datapoints that were subsequently sat to missing.Results:A total of 1,685 rheumatoid arthritis (RA) patients and 10,613 hospital visits were included in the registry. Among them, we found a number of variables that had missing values exceeding 5% of the total values. These included duration of RA (13.0%), smoking history (26.3%), rheumatoid factor (7.93%), anti-citrullinated peptide antibodies (20.5%), anti-nuclear antibodies (20.4%), sicca symptoms (19.2%), family history of a rheumatic disease (28.5%), steroid therapy (5.94%), ESR (5.16%), CRP (22.9%) and SDAI (38.0%), The results showed that among the methods used, MissForest gave the highest level of accuracy to estimate the missing values. It had the least imputation errors for both continuous and categorical variables at each frequency of missingness and it had the smallest prediction differences when the models used imputed laboratory values. In both data sets, MICE had the second least imputation errors and prediction differences, followed by KNN and mean imputation.Conclusion:MissForest is a highly accurate method of imputation for missing data in KRRD and outperforms other common imputation techniques in terms of imputation error and maintenance of predictive ability with imputed values in clinical predictive models. This approach can be used in registries to improve the accuracy of data, including the ones for rheumatoid arthritis patients.References:[1]Junninen, H.; Niska, H.; Tuppurainen, K.; Ruuskanen, J.; Kolehmainen, M.

Abstract
Extracorporeal cardiopulmonary resuscitation (eCPR) may be considered as a rescue attempt for highly selected patients with refractory cardiac arrest and potentially reversible etiology. Currently there are no randomized, controlled studies on eCPR, and valid predictors of benefit and outcome which might guide the indication for eCPR are lacking. Currently selection criteria and procedures differ across hospitals and standardized algorithms are lacking. Based on expert opinion, the present consensus statement provides a proposal for a standardized treatment algorithm for eCPR.

Abstract
Abstract
Background
Right ventricular (RV) to pulmonary artery (PA) coupling (C), quantified by pressure volume (PV) loop analysis, predicts RV function, and is independently associated with long term survival in systolic heart failure (HFrEF). However, the PV loop technique is invasive and complex to carry out, especially when used to do RV functional analyses. Different echo-surrogate parameters are proposed to measure RV-PA-C, such as the tricuspid annular plane systolic excursion, TAPSE/PAsystolic pressure (SP) and FAC (fractional area change)/PASP as the most promising parameters. However, up to now, no validation of these non-invasive coupling indices with the invasive gold standard method of RV-PV-loops has been done.
Methods
In 111 patients with advanced HFrEF (Post-hoc analysis of Magdeburger CRT Responder Trial, DRKS00011133), echo-derived TAPSE and FAC, and their relationship to PASP were related to the RV PV-loop-derived parameters of intrinsic RV contractility (Ees), pulmonary load (Ea), and the RV-PA-C efficiency (Ees/Ea) by linear regression analysis. Within a MRI substudy (n=49 patients) we examined the relationship of pure longitudinal contraction (MRI-TAPSE) and radial free wall to septum contraction (area change of 5 RV segments from tricuspid valve to apex in the short axis view) to the invasive RV-PA-C.
Results
The MRI analysis demonstrated that radial RV contraction (R2=0.77, p<0.001) correlated better to invasive RV-PA-C than pure longitudinal shortening (R2=0.37, p<0.001) (radial vs. longitudinal: p<0.00). Echo data for the entire patient cohort confirmed the MRI data. The FAC (R2=0.8, p<0.001) was significantly better associated with RV-PA-C than TAPSE (R2=0.57, p<0.001) (TAPSE vs FAC, p<0.001). Placing TAPSE or FAC into a quotient with PASP did not at all (TAPSE vs. TAPSE/PASP, p=0.1) or significantly attenuated (FAC vs. FAC/PASP R2=0.8 vs 0.58, p<0.001) their association to RV-PA-C. However, FAC/PASP and TAPSE/PASP correlated significantly better with global afterload (Eea), PA compliance, and pressure volume area (PVA), (p<0.001). In ROC analysis for all-cause mortality, all 4 tested parameters were prognostic relevant, however, with higher AUC values for FAC/PASP (AUC=0.74, p<0.001) and TAPSE/PASP (AUC=0.74, p<0.001) than for single TAPSE (AUC= 0.71, p=0.001) or FAC (AUC=0.7, p=0.001). Within a multivariate Cox regression analysis, only the FAC/PASP remained an independent predictor for long term survival.
Conclusion
FAC, an echo parameter that includes a predominant radial with a smaller part of longitudinal contraction, correlated significantly better to the invasively derived RV-PA-C-ratio than pure longitudinal RV shortening (TAPSE). Combining FAC or TAPSE with PASP did not improve the non-invasive RV-PA coupling information. However, it provided more comprehensive information on pulmonary vascular load and RV oxygen consumption, which seems to be translated into a higher prognostic power.

Abstract
AIM Injuries of the colon are a serious sequel of abdominal trauma owing to the associated morbidity and mortality. This study aims to assess postoperative outcome and complications of faecal diversion and primary repair of colon injuries when applied according to established guidelines for the management of colon injuries. METHOD This retrospective study was conducted on 110 patients with colon injuries. Guided by estimation of risk factors, patients were managed either by primary repair alone, repair with proximal diversion or diversion alone. RESULTS There were 102 (92.7%) male patients and 8 (7.3%) female patients of median age 38 years. Thirty-seven were managed by primary repair and 73 by faecal diversion. Colon injuries were caused by penetrating abdominal trauma in 65 and blunt trauma in 45 patients. Forty-three patients were in shock on admission, and were all managed by faecal diversion. Forty patients developed 84 complications after surgery. Primary repair had a significantly lower complication rate than faecal diversion (P = 0.037). Wound infection was the commonest complication. The overall mortality rate was 3.6%. CONCLUSION Primary repair, when employed properly, resulted in a significantly lower complication rate than faecal diversion. Significant predictive factors associated with a higher complication rate were faecal diversion, severe faecal contamination, multiple colon injuries, an interval of more than 12 h after colon injury and shock.

Abstract
Transcatheter aortic valve implantation (TAVI) is the new standard-of-care for inoperable patients with superior outcome compared to conservative management including balloon valvuloplasty. In high-risk patients, TAVI has shown non-inferiority compared with surgical aortic valve replacement. Although data from national multi-centre registries are very encouraging and use of TAVI in intermediate risk patients has been discussed, it is of note that the commercially available and currently used transcatheter heart valves (THV) have not yet been assessed by randomized clinical trials in those patients. New technology advances promise to simplify TAVI and to improve outcome by reducing the rate of TAVI-specific issues such as paravalvular aortic regurgitation (PAR), annular rupture, and conduction disturbances. A reduction in the incidence and severity of PAR represents an obvious target for technical improvements in the design of upcoming "next generation" THVs and of implantation techniques including repositioning/recapturing features, paravalvular sealing techniques, and precise peri-interventional imaging modalities.

Abstract
The overall goal of this project is the development of a new methodology for translating advances in molecular level understanding of toxicological responses into a predictive tool for dose response in whole animals and humans exposed to single compounds or mixtures of compounds. The methodology incorporates a mechanistic cellular level model into a PBPK (physiologically based pharmacokinetic) model which simultaneously guides the development of an in vitro cell culture analog (CCA) to the PBPK. Where the PBPK specifies an organ, (e.g., liver) the in vitro or CCA system contains a compartment with the appropriate cell or cell population (e.g., hepatocytes for the liver). The CCA has significant advantages over other in vitro systems and PBPK systems used independently for evaluating metabolic responses to drugs or potentially toxic chemicals where the exchange of metabolites between organs is likely to be important. The CCA system is superior to a PBPK because an a priori description of complete metabolism is not required and secondary, unexpected interactions can be detected. The CCA system, unlike other in vitro systems, gives a dynamic response that realistically simulates in vivo interactions between organs. Furthermore, the CCA allows dosing on the same basis as animal tests (e.g., milligrams per kilogram of body mass equivalent). Because the construction of a CCA is guided by a PBPK, this approach allows extrapolation to low doses and across species, including extrapolation to humans. We have constructed a prototype system and have conducted proof-of-concept experiments using naphthalene as a test chemical. These experiments clearly demonstrate the ability to generate a reactive metabolite in one compartment and detect its effects (on LDH release and glutathione depletion) in a second compartment. However, this prototype device would be expensive to replicate and requires nearly constant supervision from a trained investigator. For this concept to replace animals an inexpensive, self-regulating device is needed. An initial design to accomplish this goal is described as well as the corresponding model using naphthalene as a test compound. (c) 1996 John Wiley & Sons, Inc.
