RESUMEN
INTRODUCTION: Although sedation is critical in minimizing discomforts in patients, conflicting data regarding the safety of sedation among the elderly population exist. This prospective study aimed to compare the quality of recovery (QoR) from gastrointestinal endoscopy performed under sedation between elderly and younger patients. METHODS: We included 177 patients aged 40-64 (group 1, n = 66), 65-79 (group 2, n = 76), and ≥80 (group 3, n = 35) years. QoR was assessed 1 day after the procedure using the quality of recovery 15 (QoR-15) questionnaire, which is a 15-item questionnaire with scores ranging from 0 to 150. Patient demographic, procedural, and sedation data were collected, and neurocognitive function was assessed before and a day after sedation. RESULTS: Groups 1 and 3 differed according to the Mini-Cog test and 3-word memory test performed before the procedure (p < 0.001). QoR-15 scores between groups were not different (139 ± 19 group 1, 141 ± 17 group 2, and 147 ± 26 group 3; p > 0.05). Patients in groups 3 and 2 were administered lower doses of propofol and midazolam than those in group 1. The incidence of oxygen desaturation (SaO2 <90% for >30 s) was lower in groups 1 and 2 than in group 3 (p = 0.01). CONCLUSIONS: As indicated by the QoR-15 questionnaire, the QoR from sedation was not significantly different between the study groups.

AIMS: In arrhythmogenic cardiomyopathy (ACM), sustained ventricular tachycardia (VT) typically displays a left bundle branch block (LBBB) morphology while a right bundle branch block (RBBB) morphology is rare. The present study assesses the VT morphology in ACM patients with sustained VT and their clinical and genetic characteristics. METHODS AND RESULTS: Twenty-six centres from 11 European countries provided information on 954 ACM patients who had ≥1 episode of sustained VT spontaneously documented during patients' clinical course. Arrhythmogenic cardiomyopathy was defined according to the 2010 Task Force Criteria, and VT morphology according to the QRS pattern in V1. Overall, 882 (92.5%) patients displayed LBBB-VT alone and 72 (7.5%) RBBB-VT [alone in 42 (4.4%) or in combination with LBBB-VT in 30 (3.1%)]. Male sex prevalence was 79.3%, 88.1%, and 56.7% in the LBBB-VT, RBBB-VT, and LBBB + RBBB-VT groups, respectively (P = 0.007). First RBBB-VT occurred 5 years after the first LBBB-VT (46.5 ± 14.4 vs 41.1 ± 15.8 years, P = 0.011). An implanted cardioverter-defibrillator was more frequently implanted in the RBBB-VT (92.9%) and the LBBB + RBBB-VT groups (90%) than in the LBBB-VT group (68.1%) (P < 0.001). Mutations in PKP2 predominated in the LBBB-VT (65.2%) and the LBBB + RBBB-VT (41.7%) groups while DSP mutations predominated in the RBBB-VT group (45.5%). By multivariable analysis, female sex was associated with LBBB + RBBB-VT (P = 0.011) while DSP mutations were associated with RBBB-VT (P < 0.001). After a median follow-up of 103 (51-185) months, death occurred in 106 (11.1%) patients with no intergroup difference (P = 0.176). CONCLUSION: RBBB-VT accounts for a significant proportion of sustained VTs in ACM. Sex and type of pathogenic mutations were associated with VT type, female sex with LBBB + RBBB-VT, and DSP mutation with RBBB-VT.

BACKGROUND: The prognosis of patients with untreated cardiac implantable electronic device (CIED) infection is poor. Whether removal of all leads by a successful transvenous lead extraction (TLE) procedure changes the prognosis is unclear. OBJECTIVE: To identify predictors of mortality in patients with CIED infection despite successful TLE. METHODS: Retrospective single-center analysis of prospectively collected database from consecutive patients undergoing TLE at our center. Predictors for mortality were identified and a score predicting high mortality rate was calculated. RESULTS: A total of 371 consecutive patients underwent TLE, of whom 337 (90.8%) had complete hardware removal. Most were extracted due to infectious causes (81.3%). Approximately one-third (35%) died during a mean follow-up of 1056 ± 868 days. There was significantly higher mortality observed in the infectious group. Multivariate logistic regression models for infectious group only identified creatinine and albumin measurements as risk markers for 30 days mortality (odds ratio [OR], 1.68; 95% confidence interval [CI], 1.19-2.38; P = .003 and OR, 0.4; 95% CI, 0.16-0.97; P = .039, respectively). A risk score was created based on cutoff values of creatinine ≥2md/dL (1 point) and albumin ≤3.5 g/dL (1 point). A value of 2 points predicted a 50% chance of 30-day mortality and a 75% chance of 1-year mortality (P < .0001 for both). CONCLUSIONS: Creatinine and albumin can be used as a combined risk score to successfully identify patients at risk of death despite undergoing a successful TLE procedure for infectious reasons. This score could help decision making when contemplating on conservative antibiotic treatment vs TLE.

BACKGROUND: In patients with persistent atrial fibrillation (PerAF), antiarrhythmic drugs (AADs) are considered a first-line rhythm-control strategy, whereas catheter ablation is a reasonable alternative. OBJECTIVES: This study sought to examine the prevalence, patient characteristics, and clinical outcomes of patients with PerAF who underwent catheter ablation as a first or second-line strategy. METHODS: This multicenter observational study included consecutive patients with PerAF who underwent first-time ablation between January 2020 and September 2021 in 9 medical centers in the United States. Patients were divided into those who underwent ablation as first-line therapy and those who had ablation as second-line therapy. Patient characteristics and clinical outcomes were compared between the groups. RESULTS: A total of 2,083 patients underwent first-time ablation for PerAF. Of these, 1,086 (52%) underwent ablation as a first-line rhythm-control treatment. Compared with patients treated with AADs as first-line therapy, these patients were predominantly male (72.6% vs 68.1%; P = 0.03), with a lower frequency of hypertension (64.0% vs 73.4%; P < 0.001) and heart failure (19.1% vs 30.5%; P < 0.001). During a mean follow-up of 325.9 ± 81.6 days, arrhythmia-free survival was similar between the groups (HR: 1.13; 95% CI: 0.92-1.41); however, patients in the second-line ablation strategy were more likely to continue receiving AAD therapy (41.5% vs 15.9%; P < 0.001). CONCLUSIONS: A first-line ablation strategy for PerAF is prevalent in the United States, particularly in men with fewer comorbidities. More data are needed to identify patients with PerAF who derive benefit from an early intervention strategy.

BACKGROUND/AIMS: Data on the incidence of adverse respiratory events during recovery from gastrointestinal endoscopy are limited. The aim of this study was to investigate the incidence of these complications. METHODS: In this retrospective cohort study, data were obtained from the electronic records of 657 consecutive patients, who underwent gastroenterological procedures under sedation. RESULTS: Pulse oximetry oxygen saturation (SpO2) <90% for <60 seconds occurred in 82 patients (12.5%) and in 11 patients (1.7%), SpO2 of <90% for >60 seconds occurred in 79 patients (12.0%) and in 11 patients (1.7%), and SpO2 <75% occurred in four patients (0.6%) and in no patients during the procedure and recovery period, respectively. No major complications were noted. The occurrence of desaturation during recovery was correlated with desaturation during the procedure (p<0.001). American Society of Anesthesiologists score (odds ratio [OR], 1.867; 95% confidence interval [CI], 1.008-3.458), ischemic heart disease (OR, 1.815; 95% CI, 0.649-5.080), hypertension (OR, 1.289; 95% CI, 0.472-3.516), and diabetes mellitus (OR, 2.406; 95% CI, 0.950-6.095) increased the occurrence of desaturation during recovery. CONCLUSION: We found no major complications during recovery after balanced propofol-based sedation administered by a gastroenterologist-nurse team. Patients with the identified risk predictors must be monitored carefully.
RESUMEN
Cardiac implantable electronic device (CIED) infection can present with pocket or systemic manifestations, both necessitating complete device removal and pathogen-directed antimicrobial therapy. Here, we aim to characterize those presenting with both pocket and systemic infection. A retrospective analysis of CIED extraction procedures included 300 patients divided into isolated pocket (n = 104, 34.7%), complicated pocket (n = 54, 18%), and systemic infection (n = 142, 47.3%) groups. The systemic and complicated pocket groups frequently presented with leukocytosis and fever > 37.8, as opposed to the isolated pocket group. Staphylococcus aureus was the most common pathogen in the systemic and complicated pocket groups (43.7% and 31.5%, respectively), while Coagulase-negative staphylococci (CONS) predominated (31.7%) in the isolated pocket group (10.6%, p < 0.001). No differences were observed in procedural success or complications rates. Kaplan-Meier survival analysis found that at three years of follow-up, the rate of all-cause mortality was significantly higher among patients with systemic infection compared to both pocket groups (p < 0.001), with the curves diverging at thirty days. In this study, we characterize a new entity of complicated pocket infection. Despite the systemic pattern of infection, their prognosis is similar to isolated pocket infection. We suggest that this special category be presented separately in future publications of CIED infections.
RESUMEN
Given the severity of the consequences of operating room fires, it is recommended that every anaesthesiologist master fire safety protocols and periodically participate in operating room fire drills. The aim of the present study was to evaluate skill retention one year after an airway fire training programme. Anaesthesiology residents were evaluated using an airway fire simulation-based scenario one year after an educational programme that included a one-h long problem-based learning session, a simulation-based airway fire drill with debriefing, and a formal group discussion. The same simulation scenario was used for both the initial training and the one-year assessment. Thirty-eight anaesthesiology residents participated as pairs in the initial training programme. Of these, 36 participated in the evaluation a year later. Performance after one year was better than performance during the initial simulation. Time to removal of tracheal tube was 7.0 (4.0-12.8) s (median (interquartile range)) at the one-year assessment compared with 22.0 (18.5-52.5) s at the time of initial training (P < 0.001). Performance improvement was also demonstrated by a higher incidence of performance of crucial action items (cessation of airway gases, removal of sponges and pouring of saline), as well as shorter duration of time necessary to perform these tasks. After controlling the fire, the time to re-establish ventilation by bag-mask ventilation or intubation was shorter at one year: 18.0 (11.0-29.0 ) s, compared with initial training 54.0 s (36.2-69.8) s (P = 0.001). We conclude that skills are effectively retained for a year after an airway fire management training session.

Machine-learning based risk prediction models have the potential to improve patient outcomes by assessing risk more accurately than clinicians. Significant additional value lies in these models providing feedback about the factors that amplify an individual patient's risk. Identification of risk factors enables more informed decisions on interventions to mitigate or ameliorate modifiable factors. For these reasons, risk prediction models must be explainable and grounded on medical knowledge. Current machine learning-based risk prediction models are frequently 'black-box' models whose inner workings cannot be understood easily, making it difficult to define risk drivers. Since machine learning models follow patterns in the data rather than looking for medically relevant relationships, possible risk factors identified by these models do not necessarily translate into actionable insights for clinicians. Here, we use the example of risk assessment for postoperative complications to demonstrate how explainable and medically grounded risk prediction models can be developed. Pre- and postoperative risk prediction models are trained based on clinically relevant inputs extracted from electronic medical record data. We show that these models have similar predictive performance as models that incorporate a wider range of inputs and explain the models' decision-making process by visualizing how different model inputs and their values affect the models' predictions.

OBJECTIVES: Electroconvulsive therapy (ECT) is considered to be one of the most effective treatments in psychiatry. Currently, three medications for anesthesia are used routinely during ECT: propofol, etomidate, and thiopental. The objective of this study was to evaluate the effects of the anesthetics used in ECT on seizure threshold and duration, hemodynamics, recovery from ECT, and immediate side effects. METHODS: Our study is a retrospective cohort study, in which a comparison was made between three groups of patients who underwent ECT and were anesthetized with propofol, etomidate, or thiopental. The main effect compared was treatment dose and seizure duration. All patients were chosen as responders to ECT. RESULTS: Data were gathered about 91 patients (39 were anesthetized with thiopental, 29 with etomidate, and 23 with propofol). Patients in the thiopental group received a lower electrical dose compared to the propofol and etomidate group (mean of 459 mC compared to 807 mC and 701 mC, respectively, P<0.001). Motor seizure duration was longer in the thiopental group compared to propofol and etomidate (mean of 40 seconds compared to 21 seconds and 23 seconds, respectively, P=0.018). Seizure duration recorded by electroencephalography was similar in the thiopental and etomidate groups and lower in the propofol group (mean of 57 seconds in both groups compared to 45 seconds, respectively, P=0.038). CONCLUSION: Patients who were anesthetized with thiopental received a lower electrical treatment dose without an unwanted decrease in seizure duration. Thiopental might be the anesthetic of choice when it is congruent with other medical considerations.
