NIpple Position to Pinpoint Localization of Chest Drain Insertion in FEmale Trauma Patients: The NIPPLE-Trial—A Landmark Study

Background: The insertion of chest drains (CD) in trauma patients is a lifesaving, albeit high-risk intervention. Safe insertion of CD in settings where aids like ultrasound are not available relies on a landmark technique defining the so-called triangle of safety. The inferior margin of this triangle is identified by nipple height, which is thought to correspond to the fifth intercostal space (ICS). Training manikins are modeled after a lean male body and oftentimes insinuating jokes fuel uncertainty about the height of the nipple as a reliable landmark in female trauma patients. This study aims to prove that the nipple can be considered a safe landmark for CD insertion in women: even if larger breasts follow the force of gravity, it should not act towards the direction of the feet, but to the sides of the thorax in a flat-lying trauma patient. Methods: An online questionnaire was designed and distributed amongst female surgeons. Epidemiological data (age, nr of pregnancies, history of breastfeeding) was collected. Height, weight, and body mass index (BMI) were reported. Chest circumference and underbust girth were self-measured. The nipple position in relation to the ICS was measured by the women while lying in a supine position. Results: 237 female surgeons completed the questionnaire. Nine questionnaires were excluded due to incomplete data sets. 20 women were excluded due to previous breast surgery. Thus, 208 participants (or 416 nipples) were included in analysis. In supine position, both nipples were located in the 5th (±0.8) intercostal space. Age, BMI, height, weight, and status post-pregnancy had no significant impact on nipple position. Interestingly, a history of breastfeeding correlated with lower nipple position. Conclusions: The nipple is a safe landmark for identifying the correct insertion position of chest drains in supine-lying female trauma patients.

Failure to Oxygenate during Cardiopulmonary Bypass; Treatment Options and Intervention Algorithm

Membrane oxygenator failure remains a concern for perfusion teams. Successful outcomes for this low-frequency, high-risk intervention are predicated on having written institutional protocols for both the oxygenator change-out procedure as well as how often the procedure is practiced by staff perfusionists. A recent review of peer-reviewed journal articles, textbooks and online resources revealed a lack of a unified intervention algorithm for failure to oxygenate during cardiopulmonary bypass (CPB). While an oxygenator change-out procedure may still be considered the gold standard for a confirmed device failure, temporizing measures exist that, in select cases, can afford time to the clinical team and even obviate the need for an oxygenator change-out procedure. We now consider the venous piggyback technique sourcing blood from the venous limb of the circuit a first-line intervention to afford enhanced patient safety while the clinical team decides on required interventions when oxygenator failure presents during CPB.

Trajectories following Impella 5.5 support are associated with initial presentation acuity.

Impella 5.5 is a temporary left ventricular assist device utilized to support patients with cardiogenic shock and those undergoing high-risk cardiac interventions. From October 2019 to January 2023, 226 patients received Impella 5.5 support at Cleveland Clinic main campus. Patients were stratified by Society for Cardiovascular Angiography and Interventions (SCAI) shock stages. Immediate post-Impella 5.5 trajectories were compared across groups. Trajectories were defined as mortality on Impella 5.5, transition to advanced heart failure therapies (durable left ventricular assist device/heart transplantation), or survival to Impella 5.5 removal without advanced therapies. Overall, 148 (65%) patients with cardiogenic shock and 78 (35%) undergoing high-risk cardiac interventions received Impella 5.5 support. SCAI stage was A in 63 (28%), B in 10 (4.4%), C in 29 (13%), D in 104 (46%), and E in 20 (8.8%). Mortality on Impella 5.5 was highest in SCAI stage E (A: 3.2%, B: 10%, C: 14%, D: 27%, E: 35%; p < 0.01). Transition to advanced therapies (durable left ventricular assist device or heart transplantation) was highest in SCAI stages C-D (A: 1.6%, B: 0.0%, C: 45%, D: 36%, E: 20%; p < 0.01). Survival to Impella removal without advanced therapies was highest in SCAI stages A-B (A: 95%, B: 90%, C: 41%, D: 38%, E: 45%; p < 0.01). Stratification by presentation acuity in candidates for Impella 5.5 insertion may help identify which patients may and may not benefit from this escalation of tailored temporary mechanical circulatory support.

Variation in Long-Term Postoperative Mortality Risk by Race/Ethnicity After Major Non-cardiac Surgeries in the Veterans Health Administration.

Few large sample studies have examined whether disparities, as measured by the proxy of race/ethnicity, are observed in long-term mortality after high-risk operations performed in a United States national health system. We compared operation year-related mortality risk by race/ethnicity after high-risk operative interventions among patients receiving care within the VHA. From the Veterans Affairs Corporate Data Warehouse and Surgical Quality Improvement Program, data were retrieved for 426,695 patients undergoing high-risk surgical procedures in non-cardiac, general, vascular, thoracic, orthopedic, neurosurgery, and genitourinary specialties between 2000 and 2018. Operation year was used as a surrogate measure of advances in technology and perioperative management. Underrepresented race/ethnicity groups were compared in a binary form with Caucasian/White race, as the reference category. The primary outcome was time to mortality, defined as death occurring at any time, due to any cause, during follow up, and after the initial, eligible surgery. The median follow-up after 537,448 operations among 426,695 patients was 4.8years. After adjustment for preoperative risk factors and demographics, long-term mortality risk decreased significantly to a hazard ratio of 0.96 (95% confidence interval, 0.962 to 0.964) over calendar time. Long-term mortality was not significantly higher among African Americans/Blacks compared to Caucasians/Whites (p = 0.22). Among Hispanics, differences in mortality risk favored Caucasians/Whites in the early years under study-a difference that dissipated as time progressed. In the most recent years, no difference in mortality was observed among Asian/Native Americans and Caucasians/Whites. Risk-adjusted long-term mortality after high-risk operations among Veterans Affairs hospitals did not significantly vary between African Americans/Blacks, Hispanics, and Asian/Native Americans groups.

Association of visceral adiposity index with sarcopenia based on NHANES data

The Visceral Adiposity Index (VAI) assesses visceral fat and related metabolic risks. However, its precise correlation with sarcopenia is unclear. This study aimed to examine this correlation. A cross-sectional analysis was conducted using NHANES data from 2011 to 2018. To correct VAI skewness, a logarithmic transformation was applied. Multiple covariates were included, and logistic regression was employed to explore the relationship between VAI and sarcopenia. Restricted cubic spline (RCS) and threshold saturation analyses were used to investigate the nonlinear relationship. Subgroup analyses evaluated the effects of various stratification factors. Sensitivity and additive analyses tested the robustness of the findings. The study included 4688 individuals. Participants with sarcopenia had significantly higher VAI values. Logistic regression revealed a significant positive connection between Log VAI and sarcopenia (OR 2.09, 95% CI 1.80–2.43) after adjusting for variables. RCS analysis showed a nonlinear correlation, identifying a breakpoint at VAI = 1.51. To the left of this breakpoint, each unit increase in VAI significantly correlated with a higher likelihood of sarcopenia (OR 2.54, 95% CI 1.74–3.79); to the right, increases in VAI did not significantly affect prevalence. Subgroup analyses suggested VAI as an independent risk factor. Sensitivity and additive analyses confirmed the main findings’ robustness. Among American adults, the VAI is significantly associated with sarcopenia, with higher VAI values potentially increasing the prevalence of sarcopenia. Monitoring VAI is critical for early identification of high-risk individuals and interventions to delay or minimize the onset and progression of sarcopenia.

Mapping Surgical Intervention Trajectories in Seriously Ill Children Receiving Palliative Care

Background/purposeDespite the prevalence of surgical intervention in seriously ill children, data is scarce regarding interventions performed based on type of serious illness. We therefore sought to evaluate the surgical interventions performed from the time of serious illness diagnosis to the present in a cohort of children receiving palliative care, including identification of the surgical specialists involved in these procedures. MethodsWe conducted a retrospective cohort analysis of surgical interventions in 197 children enrolled in a multicenter prospective cohort study (Pediatric Palliative Care Research Network SHARE Study). All surgical interventions were abstracted via clinical record review. Results189 (of 197, 96%) patients (45% female) with an average of 5.3 complex, chronic conditions (CCC) underwent 3331 surgical interventions (median = 13) by 21 specialist teams (most commonly general surgeons). Those with hematologic malignancies underwent intervention most frequently, followed by children with respiratory, genetic/metabolic, and gastrointestinal/genitourinary (GI/GU) diagnoses. Children with cardiovascular disease, malignancies, and prematurity had the shortest time between diagnosis and first intervention and between diagnosis and pediatric palliative care (PPC) services. By contrast, those with genetic, neurologic, and respiratory diagnoses had significantly longer intervals between diagnosis and intervention. ConclusionsNearly all seriously ill children receiving PPC undergo surgical intervention, and many undergo tens of interventions by a variety of subspecialist teams. Surgical intervention differs by serious illness type, with children with more acutely life-limiting illnesses undergoing high-volume, high-risk interventions in the immediate post-diagnosis period. Those with chronic, life-limiting illnesses undergo a higher lifetime volume of interventions that are relatively lower risk and more evenly distributed over time. Level of EvidenceN/A.

The use of perioperative Impella 5.5 support in high-risk cardiac surgery: a retrospective cohort study.

Although the Impella device has an established role in high-risk percutaneous intervention and cardiogenic shock, its role in open cardiac surgery remains unclear. We undertook this study to better understand the role of Impella support in cardiac surgical intervention. This is a retrospective cohort study of consecutive patients who underwent cardiac surgery with surgically placed Impella 5.5 device support from October 2020 through June 2023. Patient charts were identified and systematically reviewed for relevant information. The primary outcome for this study was patient survival to discharge. Secondary outcomes included intraoperative survival, 30-day survival and 1-year survival. From 2020-2023, ten patients underwent open cardiac surgery with Impella 5.5 support. Five patients were male and the median age was 56.5 years [interquartile range (IQR), 52-63.8 years]. Three patients (30%) presented for isolated revascularization, 3 patients (30%) presented for single valve surgical intervention, 3 patients (30%) presented for revascularization and valve intervention, and 1 patient (10%) presented for multivalve intervention. The median ejection fraction (EF) of patients was 25% (IQR, 21.25-32.5%), the median Society of Thoracic Surgeons risk score was 4.32% (IQR, 1.73-11.06%). Of the patients, 40% underwent axillary cannulation while 60% had central cannulation. Intraoperative survival was 100%, survival to discharge was 90% and 30-day survival was 80%. Our study suggests the use of surgical Impella in high-risk cardiac surgical patients is associated with acceptable survival regardless of site or timing of cannulation. However, Impella usage is associated with significant morbidity. Further investigation is warranted to better understand which patients benefit perioperative Impella support.

The impact of preoperative psychiatric intervention for postoperative delirium after major oral and maxillofacial surgery with free flap reconstruction

BackgroundPostoperative delirium (POD) is a severe complication associated with various adverse outcomes, especially in older patients. Although the incidence and risk factors for POD have been explored in general surgery, they have not been fully elucidated. Early identification of high-risk patients and active preoperative intervention are considered essential for the prevention of POD. Recently, psychiatric consultation intervention have been shown to prevent delirium. This study investigated the effect of preoperative psychiatric interventions on preventing POD in our specific surgical context. Materials and MethodsThis retrospective, single-center observational study included 86 patients who underwent major oral and maxillofacial surgery with free flap reconstruction between 2016 and 2023. The effect of psychiatric intervention were compared between patients with and without delirium. ResultsPreoperative psychiatric intervention did not reduce the incidence of POD. The incidence of POD was 29.1 %. Univariate analyses showed no significant associations between POD and any clinical variables. ConclusionThere was no difference in the incidence of POD between patients who received preoperative psychiatric intervention and those who did not, and further investigation is needed to determine the efficacy of preoperative psychiatric intervention in the prevention of POD.

High Flow Oxygen Therapy and Secondary Spontaneous Pneumothorax: A Case Report

Treatment of secondary spontaneous pneumothorax in high-risk surgical patients with chronic pulmonary disease is a challenge in standard and emergency care. The observation that supplementary oxygen may lead to better reabsorption of pneumothorax has been known for over 50 years. It can help to avoid potential high-risk interventions or surgery in multimorbid patients.

Risk factors for severe and fatal childhood unintentional injury: a systematic review protocol

BackgroundUnintentional injuries are a leading cause of death among children aged 1–19 years worldwide. Systematic reviews assessing various risk factors for different childhood injuries have been published previously. However, most of the related literature does not distinguish minor from severe or fatal injuries. This study aims to describe and summarize the current knowledge on the determinants of severe and fatal childhood unintentional injuries and to discuss the differences between risk factors for all injuries (including minor injuries) and severe and fatal injuries. The study also aims to quantify the reduction in childhood injuries associated with a reduction in exposure to some of the identified risk factors in the Canadian population.MethodsA systematic review and meta-analysis will be conducted by searching MEDLINE, Embase, CINAHL, and Web of Science. Observational and experimental cohort studies assessing children and adolescents aged ≤ 19 years old and determinants of severe and fatal unintentional injury, such as personal behaviors, family and environmental characteristics, and socioeconomic and geographic context, will be eligible. The main outcome will be a composite of any severe or fatal unintentional injuries (including burns, drowning, transport-related injuries, and falls). Any severity measurement scale will be accepted as long as severe cases require at least one hospital admission. Two authors will independently screen for inclusion, extract data, and assess the quality of the data using the Cochrane ROBINS-E tool. Meta-analysis will be performed using random effects models. Subgroup analyses will examine age subgroups and high- vs low-income countries. Sensitivity analysis will be conducted after restricting analyses to studies with a low risk of bias. Attributable fractions will be computed to assess the burden of identified risk factors in the Canadian population.DiscussionGiven the numerous determinants of childhood injuries and the challenges that may be involved in identifying which individuals should be prioritized for injury prevention efforts, this evidence may help to inform the identification of high-risk children and prevention interventions, considering the disproportionate consequences of severe and fatal injuries. This evidence may also help pediatric healthcare providers prioritize counseling messaging.Systematic review registrationPROSPERO CRD42023493322.

A two-tier feature selection method for predicting mortality risk in ICU patients with acute kidney injury

Acute kidney injury (AKI) is one of the most important lethal factors for patients admitted to intensive care units (ICUs), and timely high-risk prognostic assessment and intervention are essential to improving patient prognosis. In this study, a stacking model using the MIMIC-III dataset with a two-tier feature selection approach was developed to predict the risk of in-hospital mortality in ICU patients admitted for AKI. External validation was performed using separate MIMIC-IV and eICU-CRD. The area under the curve (AUC) was calculated using the stacking model, and features were selected using the Boruta and XGBoost feature selection methods. This study compares the performance of a stacking model using two-tier feature selection with a model using single-tier feature selection (XGBoost: 85; Boruta: 83; two-tier: 0.91). The predictive effectiveness of the stacking model was further validated by using different datasets (Validation 1: 0.83; Validation 2: 0.85) and comparing it with a simpler model and traditional clinical scores (SOFA: 0.65; APACH IV: 0.61). In addition, this study combined interpretable techniques and causal inference to analyze the causal relationship between features and predicted outcomes.

Intracoronary imaging guidance of percutaneous coronary interventions: how and when to apply validated metrics to improve the outcome.

Percutaneous coronary intervention (PCI) is still burdened by a substantial number of complications despite constant technological advances, including the advent of intracoronary imaging (ICI) techniques. ICI modalities have been instrumental for the understanding the mechanism of PCI failure. Thanks to the ability to detail the pre-intervention coronary anatomy and identify the features indicative of sub-optimal stent deployment, ICI techniques can be utilised to improve coronary interventions in different clinical scenarios. More recently large randomized clinical trials on ICI guidance confirmed the clinical effectiveness of this approach especially in complex high-risk interventions.

Incidence, Predictors, and Outcomes of Clinically Significant Post-ERCP Bleeding: a Contemporary Multi-center Study.

Clinically significant post-endoscopic retrograde cholangiopancreatography (ERCP) bleeding (CSPEB) is common. Contemporary estimates of risk are lacking. We aimed to identify risk factors for and outcomes following CSPEB. We analyzed multi-center prospective ERCP data between 2018-2023 with 30-day follow-up. The primary outcome was CSPEB, defined as hematemesis, melena, or hematochezia resulting in: hemoglobin drop ≥20 g/L or transfusion and/or endoscopy to evaluate suspected bleeding, and/or unplanned healthcare visitation and/or prolongation of existing admission. Firth logistic regression was employed. P-values <0.05 were significant, with odds ratios (ORs) and 95% confidence intervals reported. CSPEB occurred following 129 (1.5%) of 8,517 ERCPs (mean onset 3.2 days), with 110 of 4,849 events (2.3%) occurring following higher-risk interventions (sphincterotomy, sphincteroplasty, pre-cut sphincterotomy, and/or needle-knife access). CSPEB patients required endoscopy and transfusion in 86.0% and 53.5% of cases, respectively, with three cases (2.3%) being fatal. P2Y12 inhibitors were held for a median of 4 days (IQR 4) prior to higher-risk ERCP. Following higher-risk interventions, P2Y12 inhibitors (OR 3.33, 1.26-7.74), warfarin (OR 8.54, 3.32-19.81), dabigatran (OR 13.40, 2.06-59.96), rivaroxaban (OR 7.42, 3.43-15.24) and apixaban (OR 4.16, 1.99-8.20) were associated with CSPEB. Significant intraprocedural bleeding post sphincterotomy (OR 2.32, 1.06-4.60), but not post sphincteroplasty, was also associated. Concomitant cardiorespiratory events occurred more frequently within 30 days following CSPEB (OR 12.71, 4.75-32.54). Risks of antiplatelet-related CSPEB may be underestimated by endoscopists based on observations of suboptimal holding before higher-risk ERCP. Appropriate periprocedural antithrombotic management is essential and could represent novel quality initiative targets.

Improving Linkage for Patients With Injection-Drug-Use-Related Endocarditis and Osteomyelitis to Medications for Opioid Use Disorder Through a Telephone Intervention.

The opioid overdose crisis has continued to worsen, with a concomitant increase in serious injection-related infections, such as endocarditis and osteomyelitis. Usual care of these infections involves long-term intravenous antibiotics, typically administered via a peripherally inserted central venous catheter (PICC) at home. In patients with a history of opioid use disorder who inject drugs, a PICC has long been viewed as a high-risk intervention that may contribute to illicit substance use due to ease of venous access; thus, providers are often uncomfortable discharging these patients home to complete their antibiotics. As a result, many patients remain hospitalized or are discharge to skilled nursing facilities (SNFs) in order to complete their antibiotics. Challenges to this model include difficulty finding SNFs that will accept these patients, inability for these SNFs to continue their medication for opioid use disorder (MOUD), and inability to coordinate care with outpatient MOUD providers at SNF discharge. This quality improvement project sought to increase linkage to outpatient MOUD on SNF discharge via a telephone intervention. A total of 11 patients qualified for this intervention. Although patients were still in an SNF, 4/7 (57.1%) of patients were successfully contacted. Once they were discharged from the SNF, only 3/10 (30.0%) of patients were successfully reached. Of those 30.0% who were contacted, all of them had attended their outpatient MOUD appointment. We suggest that future linkage interventions in this population may benefit from utilizing existing care team members to facilitate linkage, to maximize the rapport built during an inpatient stay.

Association Between Pack-Years and Smoking Cessation on Outcomes After Vascular Interventions

IntroductionThe influence of pack-year history and smoking cessation timing on postoperative morbidity and mortality in a highly comorbid cohort is uncertain. We examined whether the association between smoking and adverse postoperative events is modified by pack-year history and smoking cessation timing. MethodsWe collected single-institution, retrospective data from consecutive patients undergoing open operations for carotid, aortic, and infrainguinal arterial disease. Active smoking was defined as smoking on the day of the index surgical intervention. Duration of smoking cessation was calculated as the time between smoking cessation and index surgery. The primary outcome was a composite of 30-day mortality and morbidity. Logistic and time-to-event Cox regressions estimated associations with interactions between cessation duration and pack-year history for nonactive smokers. ResultsBetween 2010 and 2019, 1087 patients underwent 1640 high-risk vascular interventions. Median pack-year history was 40.0 pack-years (interquartile range [IQR]: 20.0-60.0) among nonactive smokers and 46.0 pack-years (IQR: 31.0-61.0) among active smokers (P < 0.001). The median smoking cessation time was 15.5 y (IQR: 4.4-30.9). Smoking status did not independently predict an increased risk of postoperative mortality or morbidity (odds ratio [OR] = 0.99, P = 0.96). Among nonactive smokers, neither smoking cessation duration (OR = 0.99, P = 0.16) nor pack-year history (OR = 1.00, P = 0.88) were significantly associated with adverse events (interaction P = 0.11). ConclusionsAfter high-risk vascular interventions in a single institution, active smoking, cessation period, and pack-year history are not associated with an increased risk of postoperative morbidity or mortality—highlighting the benefit of cessation as independent of frequency or intensity.

Correlation between newborn weight and serum BCAAs in pregnant women with diabetes

BackgroundBranched-chain amino acids (BCAAs), including leucine, isoleucine, and valine, are essential amino acids for mammals. Maternal BCAAs during pregnancy have been associated with newborn development. Meanwhile, BCAAs have been tightly linked with insulin resistance and diabetes in recent years. Diabetes in pregnancy is a common metabolic disorder. The current study aims to assess the circulating BCAA levels in pregnant women with diabetes and their relationship with neonatal development.MethodsThe serum concentrations of BCAAs and their corresponding branched-chain α-keto acids (BCKAs) catabolites in 33 pregnant women with normal glucose tolerance, 16 pregnant women with type 2 diabetes before pregnancy (PDGM), and 15 pregnant women with gestational diabetes mellitus (GDM) were determined using a liquid chromatography system coupled to a mass spectrometer. The data were tested for normal distribution and homogeneity of variance before statistical analysis. Correlations were computed with the Pearson correlation coefficient.ResultsThe maternal serum BCAAs and BCKAs levels during late pregnancy were higher in women with PGDM than those in healthy women. Meanwhile, the circulating BCAAs and BCKAs showed no significant changes in women with GDM compared with those in healthy pregnant women. Furthermore, the circulating BCAA and BCKA levels in women with PGDM were positively correlated with the weight of the newborn. The circulating leucine level in women with GDM was positively correlated with the weight of the newborn. BCAA and BCKA levels in healthy pregnant women showed no correlation with newborn weight.ConclusionsThe serum BCAAs in pregnant women with diabetes, which was elevated in PGDM but not GDM, were positively correlated with newborn weight. These findings highlight potential approaches for early identification of high-risk individuals and interventions to reduce the risk of adverse pregnancy outcomes.

The prevalence and clinical features of syncope in patients with concealed Brugada Syndrome

Abstract Background Brugada Syndrome (BS) is an inherited rhythm-disorder with risk of sudden-cardiac-death defined by a specific ST-segment elevation pattern in precordial ECG-leads either spontaneous or provoked by Na-channel-blocker-drug-provocation-test with Ajmaline. Scarce data denote that the prevalence of non-arrhythmic syncope is high in BS and leads to diagnostic confusions. Head-up tilt test (HUT) is a diagnostic tool used to assess autonomic function in patients with suspicious syncopal events. Purpose Our aim was to elucidate the frequency of non-arrhythmic syncope in BS patients, compare it with non-BS population with suspicious syncope and reveal possible clinical relations. Methods Adult patients with an history of Ajmaline-induced BS and patients evaluated for suspicious syncope with non-arrhyhtmic-features without BS less than 55-years-old were prospectively and consecutively evaluated with resting and higher-inter-costal-space-ECGs (HICS-ECGs), cardiac-examination and routine HUT in our center. After the exclusion of subjects with resuscitated-sudden cardiac-death/documented-malignant-dysrhythmia, any cardiac-disease, anti-arrhythmic-use, bundle-branch-blocks, pre-excitations and ventricular hypertrophies; 52 BS(+) subjects ([mean±SD] age, 33,6±14, [range]18-55 years) (male n [%overall]:33 [63.2%]) and 35 age-sex matched BS(-)subjects ([mean±SD] age, 34,1±13, [range]18-55 years) were enrolled in the study. All ECGs and HUT test results were interpreted manually by two experienced cardiologists for BS and Brugada-type-ECG-patterns (BTEPs). Results The clinical characteristics of patients with and without BS and statistical findings are presented in Table-1. BS(+) patients were slimmer, revealing more BTEPs by baseline HICS-ECGs. Baseline heart-rates were lower, PR-intervals and P-wave-duration were significantly higher in BS(+) patients. HUT-positivity of BS(+) patients were significantly higher [(39% (n: 20 [male n: 13]) vs 19% (n: 7 [male n: 4]) (p= 0,01)] revealing significantly more mixed-syncope and orthostatic hypotension response in BS(+) subjects. No cardioinhibitory response was revealed. Conclusions Non arrhtymic syncope is found to be highly prevalent in middle-aged-subjects and especially males with BS (+) without an apparent cardiac-disorder. Knowing this considerably important clinical aspect might effect risk stratification algorithms and might prevent unnecessary high-risk interventions and device decisions. Non-invasive indices regarding the delayed conduction features in ECG characteristics of BS(+) patients and a higher vagal state might be proposed as one of the probable mechanisms revealing the higher prevalence of non-arrhythmic-syncope in BS.Table-1

Safety and efficacy of percutaneous lead extraction of infected cardiac electronic devices: a single-center study

Abstract Funding Acknowledgements None. Background Infections of implanted cardiac electronic devices (CIEDs) are associated with increased morbidity and mortality. Current guidelines recommend either percutaneous or surgical lead removal. Purpose To assess and document the safety and efficacy of percutaneous lead extraction within our Electrophysiology (EP) Lab over the past 2 years. Methods We enrolled consecutive patients with CIED-related infections who underwent percutaneous lead extractions at our EP lab. Results A total of 26 consecutive patients were included in the study, of whom 21 (81%) were males, with a median age of 67 years. Among these patients, 9 (35%) had permanent pacemakers, 11 (42%) had implantable defibrillator systems, and 6 (23%) had biventricular defibrillator systems. Device extrusion was observed in 17 patients (65%), while the remaining 9 (35%) had lead vegetations. Among the 17 patients with device extrusion, 3 (18%) also had lead vegetations, but only 2 (12%) had positive blood cultures. Among the 9 patients without device extrusion, 5 (56%) had vegetations in the leads and tricuspid valve, while 4 (44%) had positive blood cultures. The mean duration from CIED implantation to infection was 81.5 months. Percutaneous lead extraction of CIEDs was successful in 25 patients (96%) using transvenous rotational dilators and endovascular lead extraction tools. In one patient, femoral access with a snare was required for lead retrieval. In another case, where complete lead removal was necessary, the patient developed a massive pulmonary embolism, leading to surgical removal. Additionally, in one patient with a 20-year-old permanent pacemaker, lead extraction was not successful; however, surgical removal was avoided due to the high risk involved. Conclusions The use of transvenous rotational dilators and endovascular lead extraction tools for transvenous removal of CIEDs due to extrusion and/or endocarditis is safe and highly effective, avoiding high-risk cardiac surgical interventions.

Geriatric End-of-Life Screening Tool Prediction of 6-Month Mortality in Older Patients

Emergency department (ED) visits by older adults with life-limiting illnesses are a critical opportunity to establish patient care end-of-life preferences, but little is known about the optimal screening criteria for resource-constrained EDs. To externally validate the Geriatric End-of-Life Screening Tool (GEST) in an independent population and compare it with commonly used serious illness diagnostic criteria. This prognostic study assessed a cohort of patients aged 65 years and older who were treated in a tertiary care ED in Boston, Massachusetts, from 2017 to 2021. Patients arriving in cardiac arrest or who died within 1 day of ED arrival were excluded. Data analysis was performed from August 1, 2023, to March 27, 2024. GEST, a logistic regression algorithm that uses commonly available electronic health record (EHR) datapoints and was developed and validated across 9 EDs, was compared with serious illness diagnoses as documented in the EHR. Serious illnesses included stroke/transient ischemic attack, liver disease, cancer, lung disease, and age greater than 80 years, among others. The primary outcome was 6-month mortality following an ED encounter. Statistical analyses included area under the receiver operating characteristic curve, calibration analyses, Kaplan-Meier survival curves, and decision curves. This external validation included 82 371 ED encounters by 40 505 unique individuals (mean [SD] age, 76.8 [8.4] years; 54.3% women, 13.8% 6-month mortality rate). GEST had an external validation area under the receiver operating characteristic curve of 0.79 (95% CI, 0.78-0.79) that was stable across years and demographic subgroups. Of included encounters, 53.4% had a serious illness, with a sensitivity of 77.4% (95% CI, 76.6%-78.2%) and specificity of 50.5% (95% CI, 50.1%-50.8%). Varying GEST cutoffs from 5% to 30% increased specificity (5%: 49.1% [95% CI, 48.7%-49.5%]; 30%: 92.2% [95% CI, 92.0%-92.4%]) at the cost of sensitivity (5%: 89.3% [95% CI, 88.8-89.9]; 30%: 36.2% [95% CI, 35.3-37.1]). In a decision curve analysis, GEST outperformed serious illness criteria across all tested thresholds. When comparing patients referred to intervention by GEST with serious illness criteria, GEST reclassified 45.1% of patients with serious illness as having low risk of mortality with an observed mortality rate 8.1% and 2.6% of patients without serious illness as having high mortality risk with an observed mortality rate of 34.3% for a total reclassification rate of 25.3%. The findings of this study suggest that both serious illness criteria and GEST identified older ED patients at risk for 6-month mortality, but GEST offered more useful screening characteristics. Future trials of serious illness interventions for high mortality risk in older adults may consider transitioning from diagnosis code criteria to GEST, an automatable EHR-based algorithm.
