RESUMEN
PURPOSE: Clinical decision support systems (CDSS) are used to identify drugs with potential need for dose modification in patients with renal impairment. ChatGPT holds the potential to be integrated in the electronic health record (EHR) system to give such dosing advices. In this study, we aim to evaluate the performance of ChatGPT in clinical rule-guided dose interventions in hospitalized patients with renal impairment. METHODS: This cross-sectional study was performed at Tergooi Medical Center, the Netherlands. CDSS alerts regarding renal dysfunction were collected from the electronic health record (EHR) during a 2-week period and were presented to ChatGPT and an expert panel. Alerts were presented with and without patient variables. To evaluate the performance, suggested medication interventions were compared. RESULTS: In total, 172 CDDS alerts were generated for 80 patients. Indecisive responses by ChatGPT to alerts were excluded. For alerts presented without patient variables, ChatGPT provided "correct and identical" responses to 19.9%, "correct and different" responses to 26.7%, and "incorrect responses to 53.4% of the alerts. For alerts including patient variables, ChatGPT provided "correct and identical" responses to 16.7%, "correct and different" responses to 16.0%, and "incorrect responses to 67.3% of the alerts. Accuracy was better for newer drugs such as direct oral anticoagulants. CONCLUSION: The performance of ChatGPT in clinical rule-guided dose interventions in hospitalized patients with renal dysfunction was poor. Based on these results, we conclude that ChatGPT, in its current state, is not appropriate for automatic integration into our EHR to handle CDSS alerts related to renal dysfunction.

BACKGROUND: Health-related quality of life (HRQOL) is becoming an increasingly important outcome in kidney transplantation (KT). To describe HRQOL in kidney transplant recipients (KTRs), this systematic review summarizes literature that compared HRQOL among KTRs and other relevant populations [i.e. patients receiving dialysis, patients on the waiting list (WL) for KT, patients with chronic kidney disease (CKD) not receiving renal replacement therapy (RRT), the general population (GP) and healthy controls (HCs)] and themselves before KT. METHODS: The literature search was conducted in PubMed, Embase, Web of Science and the Cochrane Library. Eligible studies published between January 2000 and October 2020 were included. RESULTS: Forty-four studies comprising 6929 KTRs were included in this systematic review. Despite the study heterogeneity, KTRs reported a higher HRQOL after KT compared with pre-transplantation and compared with patients receiving dialysis with or without being on the WL, especially in disease-specific domains (i.e. burden and effects of kidney disease). Additionally, KTRs had similar to marginally higher HRQOL compared with patients with CKD Stages 3-5 not receiving RRT. When compared with HCs or the GP, KTRs reported similar HRQOL in the first 1 or 2 years after KT and lower physical HRQOL and lower to comparable mental HRQOL in studies with longer post-transplant time. CONCLUSIONS: The available evidence suggests that HRQOL improves after KT and can be restored to but not always maintained at pre-CKD HRQOL levels. Future studies investigating intervention targets to improve or maintain post-transplant HRQOL are needed.

Graft function and patient survival are traditionally the most used parameters to assess the objective benefits of kidney transplantation. Monitoring graft function, along with therapeutic drug concentrations and transplant complications, comprises the essence of outpatient management in kidney transplant recipients (KTRs). However, the patient's perspective is not always included in this process. Patients' perspectives on their health after kidney transplantation, albeit subjective, are increasingly acknowledged as valuable healthcare outcomes and should be considered in order to provide patient-centred healthcare. Such outcomes are known as patient-reported outcomes (PROs; e.g. health-related quality of life and symptom burden) and are captured using PRO measures (PROMs). So far, PROMs have not been routinely used in clinical care for KTRs. In this review we will introduce PROMs and their potential application and value in the field of kidney transplantation, describe commonly used PROMs in KTRs and discuss structural PROMs implementation into kidney transplantation care.
RESUMEN
Aspirin is used for cardiovascular disease (CVD) prevention by millions of patients on a daily basis. Previous studies suggested that aspirin intake at bedtime reduces blood pressure compared with intake on awakening. This has never been studied in patients with CVD. Moreover, platelet reactivity and CVD incidence is highest during morning hours. Bedtime aspirin intake may attenuate morning platelet reactivity. This clinical trial examined the effect of bedtime aspirin intake compared with intake on awakening on 24-hour ambulatory blood pressure measurement and morning platelet reactivity in patients using aspirin for CVD prevention. In this randomized open-label crossover trial, 290 patients were randomized to take 100 mg aspirin on awakening or at bedtime during 2 periods of 3 months. At the end of each period, 24-hour blood pressure and morning platelet reactivity were measured. The primary analysis population comprised 263 (blood pressure) and 133 (platelet reactivity) patients. Aspirin intake at bedtime did not reduce blood pressure compared with intake on awakening (difference systolic/diastolic: -0.1 [95% confidence interval, -1.0, 0.9]/-0.6 [95% confidence interval, -1.2, 0.0] mm Hg). Platelet reactivity during morning hours was reduced with bedtime aspirin intake (difference: -22 aspirin reaction units [95% confidence interval, -35, -9]). The intake of low-dose aspirin at bedtime compared with intake on awakening did not reduce blood pressure of patients with CVD. However, bedtime aspirin reduced morning platelet reactivity. Future studies are needed to assess the effect of this promising simple intervention on the excess of cardiovascular events during the high risk morning hours.

AIMS: Late stent malapposition (LSM) may be acquired (LASM) or persistent. LSM may play a role in patients who develop late stent thrombosis (ST). Our objective was to compare the risk of LASM in bare metal stents (BMS) with drug-eluting stents (DES) and to investigate the possible association of both acquired and persistent LSM with (very) late ST. METHODS AND RESULTS: We searched PubMed and relevant sources from January 2002 to December 2007. Inclusion criteria were: (a) intra-vascular ultrasonography (IVUS) at both post-stent implantation and follow-up; (b) 6-9-month-follow-up IVUS; (c) implantation of either BMS or the following DES: sirolimus, paclitaxel, everolimus, or zotarolimus; and (d) follow-up for LSM. Of 33 articles retrieved for detailed evaluation, 17 met the inclusion criteria. The risk of LASM in patients with DES was four times higher compared with BMS (OR = 4.36, CI 95% 1.74-10.94) in randomized clinical trials. The risk of (very) late ST in patients with LSM (five studies) was higher compared with those without LSM (OR = 6.51, CI 95% 1.34-34.91). CONCLUSION: In our meta-analysis, the risk of LASM is strongly increased after DES implantation compared with BMS. Furthermore, LSM seems to be associated with late and very late ST.

Studies have shown that aspirin may decrease blood pressure when given at bedtime but not when administered on awakening. However, until now, a biologically plausible mechanism of this striking phenomenon was not revealed. We investigated the effect of 100 mg of aspirin administered at bedtime compared with administration on awakening on plasma renin activity and aldosterone levels over 24 hours and excretion of cortisol and catecholamines in 24-hour urine samples. A randomized, placebo-controlled, double-blind, crossover trial was performed in 16 grade 1 hypertensive subjects. During 2 periods of 2 weeks separated by a 4-week washout period, participants used aspirin both at morning and at night, which was blinded with placebo. After both periods, subjects were admitted for 24 hours to measure the aforementioned parameters. Aspirin intake at bedtime compared with on awakening reduced average (24-hour) plasma renin activity by 0.08 microg/L per hour (95% CI: 0.03 to 0.13 microg/L per hour; P=0.003) without affecting aldosterone levels (95% CI: -0.01 to 0.01 nmol/L; P=0.93). Cortisol excretion in 24-hour urine was 52 nmol/24 hours (95% CI: 5 to 99 nmol/24 hours; P=0.05) lower, and dopamine and norepinephrine excretions were 0.25 micromol/24 hours (95% CI: 0.01 to 0.48 micromol/24 hours; P=0.04) and 0.22 micromol/24 hours (95% CI: -0.03 to 0.46 micromol/24 hours; P=0.02) lower in patients treated with bedtime aspirin. In conclusion, aspirin taken at bedtime compared with on awakening significantly diminished 24-hour plasma renin activity and excretion of cortisol, dopamine, and norepinephrine in 24-hour urine. Decreased activity of these pressor systems forms a biologically plausible explanation for the finding that aspirin at night may reduce blood pressure, whereas aspirin at morning does not.

BACKGROUND: The risk of recurrence of cardiovascular events among patients using aspirin (acetylsalicylic acid) for secondary prevention of such events remains high. Persistent platelet reactivity despite aspirin therapy, a laboratory-defined phenomenon called aspirin resistance (hereinafter, laboratory aspirin resistance), might explain this in part, but its actual contribution to the risk remains unclear. The objective of this study was to systematically review all available evidence on whether laboratory aspirin resistance is related to a higher risk of cardiovascular recurrent events. METHODS: Using a predefined search strategy, we searched electronic databases. To be included in our analysis, articles had to report on patients who used aspirin for secondary cardiovascular prevention, had to contain a clear description of a method to establish the effects of aspirin on platelet reactivity, and had to report recurrence rates of cardiovascular events. Odds ratios of cardiovascular outcome of eligible studies were pooled in a random-effects model. RESULTS: We included 15 full-text articles and 1 meeting abstract. Fifteen of these studies revealed an adverse association between laboratory aspirin resistance and occurrence of cardiovascular events. The pooled odds ratio of all cardiovascular outcomes was 3.8 (95% confidence interval, 2.3-6.1) for laboratory aspirin resistance. CONCLUSION: This systematic review and meta-analysis shows that patients biochemically identified as having laboratory aspirin resistance are more likely to also have "clinical resistance" to aspirin because they exhibit significantly higher risks of recurrent cardiovascular events compared with patients who are identified as (laboratory) aspirin sensitive.

BACKGROUND: Despite clopidogrel therapy, patients undergoing percutaneous coronary intervention (PCI) with stenting are at risk of recurrent coronary events. This could be partly explained by a reduced efficacy of clopidogrel to inhibit platelet aggregation, an ex vivo defined phenomenon called clopidogrel nonresponsiveness or resistance. However, both prevalence and associated cardiovascular risks remain unclear. We systematically reviewed evidence on prevalence and clinical consequences of laboratory clopidogrel nonresponsiveness in patients undergoing PCI. METHODS: Using predefined strategies, we searched electronic databases. To be included, articles should report on PCI patients treated with clopidogrel, contain a clear description of the method used to establish the effects of clopidogrel, and report the prevalence of clopidogrel nonresponsiveness or incidence of cardiovascular events. We analyzed prevalences with a linear mixed model that accounts for study covariates and we pooled odds ratios of clinical consequences with a random-effects model. RESULTS: We identified 25 eligible studies that included a total of 3688 patients. Mean prevalence of clopidogrel nonresponsiveness was 21% (95% CI, 17%-25%) and was inversely correlated with time between clopidogrel loading and determination of nonresponsiveness and used loading dose. The pooled odds ratio of cardiovascular outcome was 8.0 (95% CI, 3.4-19.0). CONCLUSIONS: Laboratory clopidogrel nonresponsiveness can be found in approximately 1 in 5 patients undergoing PCI. Patients ex vivo labeled nonresponsive are likely to be also "clinically nonresponsive," as they exhibit increased risks of worsened cardiovascular outcomes. Our results indicate that use of a 600-mg clopidogrel loading dose will reduce these risks, which needs to be confirmed in large prospective studies.

BACKGROUND: The absolute risk of recurrences among patients using aspirin for prevention of cardiovascular events remains high. Persistent platelet reactivity despite aspirin therapy might explain this in part. Reported prevalences of this so-called aspirin resistance vary widely, between 0% and 57%. OBJECTIVES: The aim of the study was to systematically review all available evidence on prevalence of aspirin resistance and to study determinants of reported prevalence. METHODS: Using a predefined search strategy, we searched electronic databases MEDLINE, EMBASE, CENTRAL, and Web of Science. To be included in our analysis, articles had to contain a laboratory definition of aspirin resistance, use aspirin as secondary prevention, and report associated prevalence. RESULTS: We included 34 full-text articles and 8 meeting abstracts. The mean prevalence of aspirin resistance was 24% (95% CI 20%-28%). After adjustment for differences in definition, used dosage, and population, a statistically significant higher prevalence was found in studies with aspirin dosage < or =100 mg compared with > or =300 mg (36% [95% CI 28%-43%] vs 19% [95% CI 11%-26%], P < .0001). Studies measuring platelet aggregation using light aggregometry with arachidonic acid as an agonist had a pooled unadjusted prevalence of 6% (95% CI 0%-12%). In studies using point-of-care platelet function-analyzing devices, the unadjusted prevalence was significantly higher, at 26% (95% CI 21%-31%). CONCLUSIONS: Prevalences widely differ between studies reporting on aspirin resistance. Both aspirin dosage and the method of defining aspirin resistance strongly influence estimated prevalence, which explains found heterogeneity among studies. On average, it appears that about 1 in 4 individuals may express biochemically defined aspirin resistance.
