RET Fusion Testing in Patients With NSCLC: The RETING Study

Introduction: RET inhibitors with impressive overall response rates are now available for patients with NSCLC, yet the identi fication of RET fusions remains a dif ficult challenge. Most guidelines encourage the upfront use of next -generation sequencing (NGS), or alternatively, fluorescence in situ hybridization (FISH) or reverse transcriptase-polymerase chain reaction (RT-PCR) when NGS is not possible or available. Taken together, the suboptimal performance of single-analyte assays to detect RET fusions, although consistent with the notion of encouraging universal NGS, is currently widening some of the clinical practice gaps in the implementation of predictive biomarkers in patients with advanced NSCLC. Methods: This situation prompted us to evaluate several RET assays in a large multicenter cohort of RET fusion -positive NSCLC (n 1 / 4 38) to obtain real -world data. In addition to RNA -based NGS (the criterion standard method), all positive specimens underwent break -apart RET FISH with two different assays and were also tested by an RT-PCR assay. Results: The most common RET partners were KIF5B (78.9%), followed by CCDC6 (15.8%). The two RET NGSpositive but FISH -negative samples contained a KIF5B(15)RET(12) fusion. The three RET fusions not identi fied with RT-PCR were AKAP13(35)-RET(12) , KIF5B(24)-RET(9) and KIF5B(24)-RET(11) . All three false -negative RT-PCR cases were FISH -positive, exhibited a typical break -apart pattern, and contained a very high number of positive tumor cells with both FISH assays. Signet ring cells, psammoma bodies, and pleomorphic features were frequently observed (in 34.2%, 39.5%, and 39.5% of tumors, respectively). Conclusions: In-depth knowledge of the advantages and disadvantages of the different RET testing methodologies could help clinical and molecular tumor boards implement and maintain sensible algorithms for the rapid and effective detection of RET fusions in patients with NSCLC. The likelihood of RET false -negative results with both FISH and RT-PCR reinforces the need for upfront NGS in patients with NSCLC. (c) 2024 The Authors.

Predictive Power of the "Trigger Tool" for the detection of adverse events in general surgery: a multicenter observational validation study

Background In spite of the global implementation of standardized surgical safety checklists and evidence-based practices, general surgery remains associated with a high residual risk of preventable perioperative complications and adverse events. This study was designed to validate the hypothesis that a new “Trigger Tool” represents a sensitive predictor of adverse events in general surgery. Methods An observational multicenter validation study was performed among 31 hospitals in Spain. The previously described “Trigger Tool” based on 40 specific triggers was applied to validate the predictive power of predicting adverse events in the perioperative care of surgical patients. A prediction model was used by means of a binary logistic regression analysis. Results The prevalence of adverse events among a total of 1,132 surgical cases included in this study was 31.53%. The “Trigger Tool” had a sensitivity and specificity of 86.27% and 79.55% respectively for predicting these adverse events. A total of 12 selected triggers of overall 40 triggers were identified for optimizing the predictive power of the “Trigger Tool”. Conclusions The “Trigger Tool” has a high predictive capacity for predicting adverse events in surgical procedures. We recommend a revision of the original 40 triggers to 12 selected triggers to optimize the predictive power of this tool, which will have to be validated in future studies

Global burden and strength of evidence for 88 risk factors in 204 countries and 811 subnational locations, 1990–2021: a systematic analysis for the Global Burden of Disease Study 2021

Background: Understanding the health consequences associated with exposure to risk factors is necessary to inform public health policy and practice. To systematically quantify the contributions of risk factor exposures to specific health outcomes, the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021 aims to provide comprehensive estimates of exposure levels, relative health risks, and attributable burden of disease for 88 risk factors in 204 countries and territories and 811 subnational locations, from 1990 to 2021. Methods: The GBD 2021 risk factor analysis used data from 54 561 total distinct sources to produce epidemiological estimates for 88 risk factors and their associated health outcomes for a total of 631 risk–outcome pairs. Pairs were included on the basis of data-driven determination of a risk–outcome association. Age-sex-location-year-specific estimates were generated at global, regional, and national levels. Our approach followed the comparative risk assessment framework predicated on a causal web of hierarchically organised, potentially combinative, modifiable risks. Relative risks (RRs) of a given outcome occurring as a function of risk factor exposure were estimated separately for each risk–outcome pair, and summary exposure values (SEVs), representing risk-weighted exposure prevalence, and theoretical minimum risk exposure levels (TMRELs) were estimated for each risk factor. These estimates were used to calculate the population attributable fraction (PAF; ie, the proportional change in health risk that would occur if exposure to a risk factor were reduced to the TMREL). The product of PAFs and disease burden associated with a given outcome, measured in disability-adjusted life-years (DALYs), yielded measures of attributable burden (ie, the proportion of total disease burden attributable to a particular risk factor or combination of risk factors). Adjustments for mediation were applied to account for relationships involving risk factors that act indirectly on outcomes via intermediate risks. Attributable burden estimates were stratified by Socio-demographic Index (SDI) quintile and presented as counts, age-standardised rates, and rankings. To complement estimates of RR and attributable burden, newly developed burden of proof risk function (BPRF) methods were applied to yield supplementary, conservative interpretations of risk–outcome associations based on the consistency of underlying evidence, accounting for unexplained heterogeneity between input data from different studies. Estimates reported represent the mean value across 500 draws from the estimate's distribution, with 95% uncertainty intervals (UIs) calculated as the 2·5th and 97·5th percentile values across the draws. Findings: Among the specific risk factors analysed for this study, particulate matter air pollution was the leading contributor to the global disease burden in 2021, contributing 8·0% (95% UI 6·7–9·4) of total DALYs, followed by high systolic blood pressure (SBP; 7·8% [6·4–9·2]), smoking (5·7% [4·7–6·8]), low birthweight and short gestation (5·6% [4·8–6·3]), and high fasting plasma glucose (FPG; 5·4% [4·8–6·0]). For younger demographics (ie, those aged 0–4 years and 5–14 years), risks such as low birthweight and short gestation and unsafe water, sanitation, and handwashing (WaSH) were among the leading risk factors, while for older age groups, metabolic risks such as high SBP, high body-mass index (BMI), high FPG, and high LDL cholesterol had a greater impact. From 2000 to 2021, there was an observable shift in global health challenges, marked by a decline in the number of all-age DALYs broadly attributable to behavioural risks (decrease of 20·7% [13·9–27·7]) and environmental and occupational risks (decrease of 22·0% [15·5–28·8]), coupled with a 49·4% (42·3–56·9) increase in DALYs attributable to metabolic risks, all reflecting ageing populations and changing lifestyles on a global scale. Age-standardised global DALY rates attributable to high BMI and high FPG rose considerably (15·7% [9·9–21·7] for high BMI and 7·9% [3·3–12·9] for high FPG) over this period, with exposure to these risks increasing annually at rates of 1·8% (1·6–1·9) for high BMI and 1·3% (1·1–1·5) for high FPG. By contrast, the global risk-attributable burden and exposure to many other risk factors declined, notably for risks such as child growth failure and unsafe water source, with age-standardised attributable DALYs decreasing by 71·5% (64·4–78·8) for child growth failure and 66·3% (60·2–72·0) for unsafe water source. We separated risk factors into three groups according to trajectory over time: those with a decreasing attributable burden, due largely to declining risk exposure (eg, diet high in trans-fat and household air pollution) but also to proportionally smaller child and youth populations (eg, child and maternal malnutrition); those for which the burden increased moderately in spite of declining risk exposure, due largely to population ageing (eg, smoking); and those for which the burden increased considerably due to both increasing risk exposure and population ageing (eg, ambient particulate matter air pollution, high BMI, high FPG, and high SBP). Interpretation: Substantial progress has been made in reducing the global disease burden attributable to a range of risk factors, particularly those related to maternal and child health, WaSH, and household air pollution. Maintaining efforts to minimise the impact of these risk factors, especially in low SDI locations, is necessary to sustain progress. Successes in moderating the smoking-related burden by reducing risk exposure highlight the need to advance policies that reduce exposure to other leading risk factors such as ambient particulate matter air pollution and high SBP. Troubling increases in high FPG, high BMI, and other risk factors related to obesity and metabolic syndrome indicate an urgent need to identify and implement interventions

Efectividad a 5 años de balón farmacoactivo con paclitaxel en reestenosis de stent coronario en la práctica clínica

Introduction and objectives: Coronary in-stent restenosis (ISR) is associated with a high target lesion revascularization rate, while the drug-eluting balloon (DEB) presents IA class level of evidence for its treatment. Nevertheless, very long-term outcomes of DEB for ISR in non-selected populations of patients are unknown. Our goal is to evaluate the very long-term (5 year) effectiveness of DEBs in a real-world registry. Methods: Retrospective registry from an ISR cohort treated with DEB. The primary outcome was the rate of target lesion revascularization (TLR) at 5 years. Secondary outcomes were evaluated according to the ARC-2 criteria. Results: From January 2010 through December 2013, 53 ISRs were treated using DEBs in 48 patients. Patients were old (69.3 ± 11.8 years-old) and 55.8% had diabetes. The rate of TLR at 1 year was 9.4%, and 20.8% at 3 and 5 years, respectively. The rate of late TLR (after the first year) was 11.4%, only after DEB for bare metal ISR. The 5-year TLR was not associated with diabetes (22.7% vs 19.2%; P = .76), and was not significantly lower after cutting-balloon (12.5% vs 24.3%; P = .47) or in bare-metal stent ISR (20.6% vs 21.1%; P = .96). There was no definite/probable stent thrombosis of the lesions treated with DEB at follow-up. Conclusions: In a real-world cohort, the 5-year TLR rate after DEB for ISR was 20.8%. Late TLR accounted for half of the TLR at follow-up (after DEB for bare metal ISR), while the rate of TLR seemed to stabilize at 3 years. There was no stent thrombosis of the lesions treated with DEB.Introducción y objetivos: La reestenosis de stents coronarios (RS) presentan altas tasas de necesidad de revascularización, y el balón farmacoactivo (BFA) presenta clase I (nivel de evidencia A) en su tratamiento. La eficacia de esta estrategia a muy largo plazo en pacientes no seleccionados es desconocida. Se pretende evaluar la eficacia del BFA en un registro de pacientes de la práctica clínica a muy largo plazo de seguimiento (5 años). Métodos: Registro retrospectivo de una cohorte formada por pacientes con RS tratados con BFA. El evento primario fue la tasa de revascularización de la lesión tratada (RLT) con BFA a 5 años. Se valoraron eventos secundarios según los criterios Academic Research Consortium-2. Resultados: Entre enero de 2010 y diciembre de 2013 se usó BFA de forma eficaz en 53 RS de 48 pacientes. Los pacientes presentaban edad avanzada (69,3 ± 11,8 años) y alta prevalencia de diabetes (55,8%). La tasa de RLT a 1 año fue del 9,4%, y del 20,8% a los 3 y 5 años. La tasa de RLT tardía (más allá del año de seguimiento) fue del 11,4%, tan solo en reestenosis de stent convencional. La RLT a 5 años no se asoció a diabetes (22,7 frente a 19,2%; p = 0,76) ni fue significativamente menor con el uso de balón de corte (12,5 frente a 24,3%; p = 0,47) o en reestenosis de stent convencional (20,6 frente a 21,1%; p = 0,96). No hubo casos de trombosis de stent definitiva/probable de la lesión tratada con BFA. Conclusiones: En una cohorte de la práctica clínica, el BFA para RS presenta una RLT a 5 años del 20,8%. La RLT tardía supone la mitad de los casos a lo largo del seguimiento, y se produce en RS convencional. La tasa de RLT parece estabilizarse a partir del tercer año de seguimiento. No se evidenció trombosis de stent de la lesión tratada con BFA

Benefit of primary percutaneous coronary interventions in the elderly with ST segment elevation myocardial infarction

Objective: Primary percutaneous coronary intervention (P-PCI) has demonstrated its efficacy in patients with ST segment elevation myocardial infarction (STEMI). However, patients with STEMI ≥75 years receive less P-PCI than younger patients despite their higher in-hospital morbimortality. The objective of this analysis was to determine the effectiveness of P-PCI in patients with STEMI ≥75 years. Methods: We included 979 patients with STEMI ≥75 years, from the ATención HOspitalaria del Síndrome coronario study, a registry of 8142 consecutive patients with acute coronary syndrome admitted at 31 Spanish hospitals in 2014-2016. We calculated a propensity score (PS) for the indication of P-PCI. Patients that received or not P-PCI were matched by PS. Using logistic regression, we compared the effectiveness of performing P-PCI versus non-performance for the composite primary event, which included death, reinfarction, acute pulmonary oedema or cardiogenic shock during hospitalisation. Results: Of the included patients, 81.5 % received P-PCI. The matching provided two groups of 169 patients with and without P-PCI. Compared with its non-performance, P-PCI presented a composite event OR adjusted by PS of 0.55 (95% CI 0.34 to 0.89). Conclusions: Receiving a P-PCI was significantly associated with a reduced risk of major intrahospital complications in patients with STEMI aged 75 years or older
