RESUMO

Background: Performance validity tests (PVTs) and symptom validity tests (SVTs) are essential to neuropsychological evaluations, helping ensure findings reflect true abilities or concerns. It is unclear how PVTs and SVTs perform in children who received radiotherapy for brain tumors. Accordingly, we investigated the rate of noncredible performance on validity indicators as well as associations with fatigue and lower intellectual functioning. Methods: Embedded PVTs and SVTs were investigated in 98 patients with pediatric craniopharyngioma undergoing proton radiotherapy (PRT). The contribution of fatigue, sleepiness, and lower intellectual functioning to embedded PVT performance was examined. Further, we investigated PVTs and SVTs in relation to cognitive performance at pre-PRT baseline and change over time. Results: SVTs on parent measures were not an area of concern. PVTs identified 0-31% of the cohort as demonstrating possible noncredible performance at baseline, with stable findings 1 year following PRT. Reliable digit span (RDS) noted the highest PVT failure rate; RDS has been criticized for false positives in pediatric populations, especially children with neurological impairment. Objective sleepiness was strongly associated with PVT failure, stressing need to consider arousal level when interpreting cognitive performance in children with craniopharyngioma. Lower intellectual functioning also needs to be considered when interpreting task engagement indices as it was strongly associated with PVT failure. Conclusions: Embedded PVTs should be used with caution in pediatric craniopharyngioma patients who have received PRT. Future research should investigate different cut-off scores and validity indicator combinations to best differentiate noncredible performance due to task engagement versus variable arousal and/or lower intellectual functioning.

RESUMO

BACKGROUND: Patients with heart defects are at risk of developing cardiovascular disease. Our objective was to determine if non-cardiac birth defects are associated with the risk of cardiovascular hospitalisation. METHODS: We conducted a longitudinal cohort study of 1 451 409 parous women in Quebec, Canada. We compared patients with cardiac and non-cardiac birth defects of the urinary, central nervous and other systems against patients without defects between 1989 and 2022. The main outcome was hospitalisation for coronary artery disease, ischaemic stroke and other cardiovascular outcomes during 33 years of follow-up. We computed cardiovascular hospitalisation rates and used Cox proportional hazards regression models to measure the association (HR; 95% CI) between non-cardiac defects and later risk of cardiovascular hospitalisation, adjusted for patient characteristics. RESULTS: Women with any birth defect had a higher rate of cardiovascular hospitalisation than women without defects (7.0 vs 3.3 per 1000 person-years). Non-cardiac defects overall were associated with 1.61 times the risk of cardiovascular hospitalisation over time, compared with no defect (95% CI 1.56 to 1.66). Isolated urinary (HR 3.93, 95% CI 3.65 to 4.23), central nervous system (HR 3.33, 95% CI 2.94 to 3.76) and digestive defects (HR 2.39, 95% CI 2.16 to 2.65) were associated with the greatest risk of cardiovascular hospitalisation. These anomalies were associated with cardiovascular hospitalisation whether they presented alone or clustered with other defects. Nevertheless, heart defects were associated with the greatest risk of cardiovascular hospitalisation (HR 10.30, 95% CI 9.86 to 10.75). CONCLUSION: The findings suggest that both cardiac and non-cardiac birth defects are associated with an increased risk of developing cardiovascular disease among parous women.

RESUMO

OBJECTIVE: Sickle cell disease (SCD) is an inherited blood disorder associated with neurocognitive deficits. In contrast to variable-centered approaches, no known research has utilized person-centered strategies to identify multidimensional patterns of neurocognitive functioning of an individual with SCD. The purpose of the present study was to create empirically derived profiles and identify predictors of neurocognitive functioning subgroups among youth and young adults with SCD. METHODS: Individuals with SCD (N = 393, mean age 14.05 years, age range 8-24, 50.4% female/49.6% male) completed neurocognitive assessments. Latent profile analysis derived subgroups/classes of neurocognitive functioning and determined relations with demographic and medical variables. RESULTS: Three latent classes emerged: average functioning (n = 102, 27%), low average functioning (n = 225, 60%), and exceptionally low functioning (n = 46, 12%). Older age was associated with membership in the low average and exceptionally low functioning groups (relative to the average group). Being prescribed hydroxyurea was associated with membership in the average functioning group (relative to the low average group) and absence of hydroxyurea use was associated with membership in the exceptionally low group (relative to the low average group). Lower social vulnerability was associated with membership in the average functioning group compared to the low average and exceptionally low groups. CONCLUSIONS: Clinicians can help reduce disparities in cognitive development for individuals with SCD by promoting early treatment with hydroxyurea and implementing methods to reduce social vulnerabilities that can interfere with access to evidence-based care.

RESUMO

Longitudinal right ventricular free wall strain (RVFWS) has been identified as an independent prognostic marker in patients with pulmonary hypertension. Little is known however about the prognostic value of RVFWS in patients with sickle cell (SC) disease, particularly during exercise. We therefore examined the prognostic significance of RVFWS both at rest and with exercise in patients with SC disease and normal resting systolic pulmonary artery pressure (SPAP). Consecutive patients with SC disease referred for bicycle ergometer stress echocardiography (SE) were enrolled ftom July 2019 to January 2021. All patients had measurable tricuspid regurgitation velocity (TRV). Conventional echocardiography parameters, left ventricular global longitudinal strain (LVGLS), RVFWS, and ventriculoarterial coupling indices (TAPSE/SPAP and RVFWS/SPAP) were assessed at rest and peak exercise. Repeat SE was performed at a median follow-up of 2 years. The cohort consisted of 87 patients (mean age was 31 ± 11 years, 66% females). All patients had normal resting TRV < 2.8 m/s, RVFWS and LVGLS at baseline. There were 23 (26%) patients who had peak stress RVFWS < 20%. They had higher resting and peak stress TRV and SPAP, but lower resting and peak stress TAPSE/SPAP, RVFWS/SPAP, and LVGLS as well as lower peak stress cardiac output when compared to patients with peak stress RVFWS ≥ 20% (p < 0.05). Patients with baseline peak stress RVFWS < 20% had a significant decrease in exercise performance at follow-up (7.5 ± 2.7 min at baseline vs. 5.5 ± 2.8 min at follow-up, p < 0.001). In the multivariate analysis, baseline peak stress RVFWS was the only independent predictor of poorer exercise performance at follow-up [odds ratio 8.2 (1.2, 56.0), p = 0.033]. Among patients with SC disease who underwent bicycle ergometer SE, a decreased baseline value of RVFWS at peak stress predicted poorer exercise time at follow-up.

RESUMO

BACKGROUND: Associations of early changes in vasoactive support with cardiogenic shock (CS) mortality remain incompletely defined. METHODS: The Critical Care Cardiology Trials Network is a multicenter registry of cardiac intensive care units. Patients admitted with CS (2018-2023) had vasoactive dosing assessed at 4 and 24 hours from cardiac intensive care unit admission and quantified by the vasoactive-inotropic score (VIS). Prognostic associations of VIS at both time points, as well as change in VIS from 4 to 24 hours, were examined. Interaction testing was performed based on mechanical circulatory support status. RESULTS: Among 3665 patients, 82% had a change in VIS <10, with 7% and 11% having a ≥10-point increase and decrease from 4 to 24 hours, respectively. The 4 and 24-hour VIS were each associated with cardiac intensive care unit mortality (13%-45% and 11%-73% for VIS <10 to ≥40, respectively; Ptrend <0.0001 for each). Stratifying by the 4-hour VIS, changes in VIS from 4 to 24 hours had a graded association with mortality, ranging from a 2- to >4-fold difference in mortality comparing those with a ≥10-point increase to ≥10-point decrease in VIS (Ptrend <0.0001). The change in VIS alone provided good discrimination of cardiac intensive care unit mortality (C-statistic, 0.72 [95% CI, 0.70-0.75]) and improved discrimination of the 24-hour Sequential Organ Failure Assessment score (0.72 [95% CI, 0.69-0.74] to 0.76 [95% CI, 0.74-0.78]) and the clinician-assessed Society for Cardiovascular Angiography and Interventions shock stage (0.72 [95% CI, 0.70-0.74] to 0.77 [95% CI, 0.75-0.79]). Although present in both groups, the mortality risk associated with VIS was attenuated in patients managed with versus without mechanical circulatory support (odds ratio per 10-point higher 24-hour VIS, 1.36 [95% CI, 1.23-1.49] versus 1.84 [95% CI, 1.69-2.01]; Pinteraction <0.0001). CONCLUSIONS: Early changes in the magnitude of vasoactive support in CS are associated with a gradient of risk for mortality. These data suggest that early VIS trajectory may improve CS prognostication, with the potential to be leveraged for clinical decision-making and research applications in CS.

RESUMO

BACKGROUND: Severe lung disease frequently presents with both refractory hypoxemia and right ventricular (RV) failure. OxyRVAD is an extra-corporeal membrane oxygenation (ECMO) configuration of RV bypass that also supplements gas exchange. This systematic review summarizes the available literature regarding the use of OxyRVAD in the setting of severe lung disease with associated RV failure. METHODS: PubMed, Embase, and Google Scholar were queried on September 27th, 2023, for articles describing the use of an OxyRVAD configuration. The main outcome of interest was survival to ICU discharge. Data on the duration of OxyRVAD support and device-related complications were also recorded. RESULTS: Of 475 identified articles, 33 were retained for analysis. Twenty-one articles were case reports and 12 were case series representing a total of 103 patients. No article provided a comparison group. Most patients (76.4%) were transitioned to OxyRVAD from another type of mechanical support. OxyRVAD was used as a bridge to transplant or curative surgery in 37.4% and as a bridge to recovery or decision in 62.6%. Thirty-one patients (30.1%) were managed with the dedicated single-access dual-lumen ProtekDuo cannula. Median time on OxyRVAD was twelve days (IQR 8-23) and survival to ICU discharge was 63.9%. Device-related complications were infrequently reported. CONCLUSION: OxyRVAD support is a promising alternative for RV support when gas exchange is compromised with good ICU survival in selected cases. Comparative analyses in patients with RV failure with and without severe lung disease are needed.

RESUMO

Background: Myocardial infarction with nonobstructive coronary artery disease (MINOCA) is defined as acute myocardial infarction (AMI) with angiographically nonobstructive coronary artery disease. MINOCA represents 6% of all AMI cases and is associated with increased mortality and morbidity. However, the wide array of pathophysiological factors and causes associated with MINOCA presents a diagnostic conundrum. Therefore, we conducted a contemporary systematic review of the pathophysiology of MINOCA. Methods: A comprehensive systematic review of MINOCA was carried out through the utilization of the PubMed database. All systematic reviews, meta-analyses, randomized controlled trials, and cohort studies available in English or French that reported on the pathophysiology of MINOCA published after January 1, 2013 were retained. Results: Of the 600 identified records, 80 records were retained. Central to the concept of MINOCA is the definition of AMI, characterized by the presence of myocardial damage reflected by elevated cardiac biomarkers in the setting of acute myocardial ischemia. As a result, a structured approach should be adopted to thoroughly assess and address clinically overlooked obstructive coronary artery disease, and cardiac and extracardiac mechanisms of myocyte injury. Once these options have been ruled out, a diagnosis of MINOCA can be established, and the appropriate multimodal assessment can be conducted to determine its specific underlying cause (plaque disruption, epicardial coronary vasospasm, coronary microvascular dysfunction, and coronary embolism and/or spontaneous coronary dissection or supply-demand mismatch). Conclusions: Integrating a suitable definition of AMI and understanding the pathophysiological mechanisms of MINOCA are crucial to ensure an effective multimodal diagnostic evaluation and the provision of adequate tailored therapies.


Contexte: L'infarctus du myocarde sans obstruction des artères coronaires (MINOCA) est défini comme un infarctus aigu du myocarde (IAM) en présence d'une coronaropathie non obstructive confirmée par angiographie. Le MINOCA représente 6 % de tous les cas d'IAM et est associé à une hausse des taux de mortalité et de morbidité. Cependant, le large éventail de facteurs physiopathologiques et de causes associés au MINOCA représente une énigme diagnostique. C'est pourquoi nous avons réalisé une analyse systématique des publications contemporaines sur la physiopathologie du MINOCA. Méthodologie: Une analyse exhaustive des publications sur le MINOCA a été menée au moyen de la base de données PubMed. L'ensemble des analyses systématiques, des méta-analyses, des essais contrôlés randomisés et des études de cohorte publiés en anglais ou en français après le 1er janvier 2013 qui faisaient état de la physiopathologie du MINOCA ont été retenus. Résultats: Parmi les 600 dossiers relevés, 80 ont été retenus. La définition de l'IAM était centrale au concept de MINOCA et était caractérisée par la présence d'une lésion myocardique attestée par des taux élevés de biomarqueurs cardiaques en contexte d'ischémie myocardique aiguë. Par conséquent, une approche structurée devrait être adoptée pour évaluer pleinement et traiter les coronaropathies obstructives qui passent inaperçues en clinique ainsi que les mécanismes cardiaques et extracardiaques des lésions aux myocytes. Une fois ces options exclues, un diagnostic de MINOCA peut être établi et l'évaluation multimodale appropriée peut être menée pour déterminer la cause sous-jacente précise (rupture de plaque, vasospasme d'une artère coronaire épicardique, dysfonction microvasculaire coronarienne et embolie coronarienne et/ou dissection spontanée d'une artère coronaire ou déséquilibre entre apports et besoins). Conclusions: Il est crucial d'intégrer une définition convenable de l'IAM et de comprendre les mécanismes physiopathologiques du MINOCA pour assurer une évaluation diagnostique multimodale efficace et une prestation de traitements adaptés et adéquats.

RESUMO

Background: In patients with anterior ST-elevation myocardial infarction (STEMI) and new-onset antero-apical wall motion abnormalities (WMAs), whether the rate of prophylaxis against left ventricular thrombus and outcomes differ between men and women is unknown. Methods: A multicentre retrospective cohort study of patients with STEMI and new-onset antero-apical WMAs treated with primary percutaneous coronary intervention was conducted. Patients with an established indication of oral anticoagulation (OAC) were excluded. The rates of triple therapy (double antiplatelet therapy + OAC) at discharge were compared for women vs men. The rates of net adverse clinical events, a composite of mortality, myocardial infarction, stroke or transient ischemic attack, systemic thromboembolism or Bleeding Academic Research Consortium (BARC) type 3 or 5 bleeding at 6 months were compared across sex using a multivariate logistic regression model. Results: A total of 1664 patients were included in the primary analysis, of whom 402 (24.2%) were women and 1262 (75.8%) were men. A total of 138 women (34.3%) and 489 men (38.7%) received a triple therapy prescription at discharge (P = 0.11). At 6 months, 33 women (8.2%) and 96 men (7.6%) experienced a net adverse clinical event (adjusted odds ratio 0.82; 95% confidence interval 0.49-1.37). No difference occurred in the risk of bleeding events and ischemic events between men and women, when these were analyzed separately. Conclusions: The rates of OAC prescription for left ventricular thrombus prophylaxis and clinical outcomes at 6 months were similar in women and men following anterior STEMI with new-onset antero-apical WMAs.


Contexte: On ignore si le taux de prophylaxie contre le thrombus ventriculaire gauche et les résultats thérapeutiques diffèrent entre les hommes et les femmes qui ont subi un infarctus du myocarde avec élévation du segment ST (STEMI) antérieur et ont des anomalies du mouvement pariétal (AMP) antéroapical d'apparition récente. Méthodes: Nous avons mené une étude de cohorte rétrospective multicentrique auprès de patients qui ont subi un STEMI et ont des AMP d'apparition récente traitées par une intervention coronarienne percutanée primaire. Nous avons exclu les patients chez lesquels il existait une indication établie à l'anticoagulation orale (ACO). Nous avons comparé les taux de trithérapie (bithérapie antiplaquettaire + ACO) à la sortie de l'hôpital entre les femmes et les hommes. Nous avons comparé les taux d'événements indésirables cliniques nets, le critère composite de mortalité, d'infarctus du myocarde, d'accident vasculaire cérébral ou d'accident ischémique transitoire, la thromboembolie systémique ou l'hémorragie de type 3 ou 5 selon le Bleeding Academic Research Consortium (BARC) après 6 mois entre les sexes au moyen du modèle de régression logistique multivariée. Résultats: Au sein des 1 664 patients de l'analyse principale, 402 (24,2 %) étaient des femmes et 1262 (75,8 %) étaient des hommes. Un total de 138 femmes (34,3 %) et de 489 hommes (38,7 %) ont reçu une ordonnance de trithérapie à la sortie de l'hôpital (P = 0,11). Après 6 mois, 33 femmes (8,2 %) et 96 hommes (7,6 %) ont subi un événement indésirable net (rapport de cotes ajusté 0,82 ; intervalle de confiance à 95 % 0,49-1,37). Aucune différence n'a été notée dans le risque d'événements hémorragiques et d'événements ischémiques entre les hommes et les femmes lorsque ces événements étaient analysés séparément. Conclusions: Les taux d'ordonnances d'ACO en prophylaxie du thrombus ventriculaire gauche et les résultats cliniques après 6 mois étaient similaires entre les femmes et les hommes à la suite du STEMI antérieur et des AMP antéroapicale d'apparition récente.

RESUMO

Background: Cardiovascular disease continues to be the primary cause of premature mortality in women, who previously have been overlooked in clinical trials. Several studies showed that women undergoing coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) present more cardiovascular risk factors at baseline, develop more postprocedural complications, and have a higher mortality rate than men. The goal of this review is to analyze the difference between men and women in terms of the prevalence of individual cardiovascular risk factors. Methods: A meta-analysis was conducted of original investigations with adult subjects who underwent surgical intervention or PCIs in which cardiovascular risk factors were evaluated, using the MEDLINE, Cochrane, Evidence-Based Medicine Reviews (EBMR), Ovid Embase, Google Scholar, and PubMed databases. Results: Of the 4567 identified records found, 18 were retained for qualitative analysis. Prevalence of hypertension (CABG: 71% (95% confidence interval [CI] 64%, 78%]); PCI: (59% [95% CI 48%,70%]), and diabetes (CABG: 48% [95% CI 38%, 57%]); PCI 43% (95% CI 27%, 59%]) was high in women. Women who underwent either CABG or PCI had higher odds of having hypertension (CABG: odds ratio [OR] 1.92 [95% CI 1.47-2.50], P < 0.05); PCI: OR 1.86 [95% CI 1.76-1.97], P < 0.05]), and diabetes (CABG: OR 1.94 [95% CI 1.55-2.42], P < 0.05; PCI: OR 1.97 [95% CI 1.54-2.53], P < 0.05)). However, the prevalence of smoking among women, compared to men, was lower (CABG: 0.17 [95% CI 0.06-0.52], P < 0.05; PCI: 0.22 [95% CI 0.06-0.86], P < 0.03). Conclusion: The review shows that women who underwent either surgical or percutaneous revascularization had higher odds of hypertension and diabetes, compared to men.


Contexte: Les maladies cardiovasculaires demeurent la principale cause de décès prématurés chez les femmes, qui ont antérieurement été négligées dans les essais cliniques. Or, plusieurs études ont révélé que les femmes qui subissent un pontage aortocoronarien (PAC) ou une intervention coronarienne percutanée (ICP) présentent initialement plus de facteurs de risque cardiovasculaire, connaissent plus de complications postopératoires et affichent un taux de mortalité plus élevé que les hommes. Cette analyse visait à dégager les différences entre les hommes et les femmes quant à la prévalence de chacun des facteurs de risque cardiovasculaire. Méthodologie: Une méta-analyse a été menée sur des enquêtes originales auprès d'adultes ayant subi une intervention chirurgicale ou des ICP chez qui les facteurs de risque cardiovasculaire ont été évalués. Les bases de données interrogées étaient les suivantes : MEDLINE, Cochrane, Evidence-Based Medicine Reviews (EBMR), Ovid Embase, Google Scholar et PubMed. Résultats: Parmi les 4567 dossiers recensés, 18 ont été retenus pour une analyse qualitative. La prévalence de l'hypertension (PAC : 71 % [intervalle de confiance {IC} à 95 % : 64 %; 78 %]); ICP : 59 % [IC à 95 % : 48 %; 70 %]) et du diabète (PAC : 48 % [IC à 95 % : 38 %; 57 %]); ICP : 43 % (IC à 95 % : 27 %; 59 %]) était élevée chez les femmes. Les femmes qui ont subi un PAC ou une ICP présentaient un risque accru d'hypertension (PAC : rapport de cotes [RC] de 1.92 [IC à 95 % : 1,47-2,50], p < 0,05); ICP : RC de 1,86 [IC à 95 % : 1,76-1,97], p < 0,05]) et de diabète (PAC : RC de 1,94 [IC à 95 % : 1,55-2,42], p < 0,05; ICP : RC de 1,97 [IC à 95 % : 1,54-2,53], p < 0,05). Cependant, le tabagisme était moins prévalent chez les femmes que chez les hommes (PAC : 0,17 [IC à 95 % : 0,06-0,52], p < 0,05; ICP : 0,22 [IC à 95 % : 0,06-0,86], p < 0,03). Conclusion: L'analyse révèle que, par rapport aux hommes, les femmes qui ont subi une revascularisation chirurgicale ou percutanée présentaient plus de risque d'hypertension et de diabète.

RESUMO

BACKGROUND: Wide interhospital variations exist in cardiovascular intensive care unit (CICU) admission practices and the use of critical care restricted therapies (CCRx), but little is known about the differences in patient acuity, CCRx utilization, and the associated outcomes within tertiary centers. METHODS: The Critical Care Cardiology Trials Network is a multicenter registry of tertiary and academic CICUs in the United States and Canada that captured consecutive admissions in 2-month periods between 2017 and 2022. This analysis included 17 843 admissions across 34 sites and compared interhospital tertiles of CCRx (eg, mechanical ventilation, mechanical circulatory support, continuous renal replacement therapy) utilization and its adjusted association with in-hospital survival using logistic regression. The Pratt index was used to quantify patient-related and institutional factors associated with CCRx variability. RESULTS: The median age of the study population was 66 (56-77) years and 37% were female. CCRx was provided to 62.2% (interhospital range of 21.3%-87.1%) of CICU patients. Admissions to CICUs with the highest tertile of CCRx utilization had a greater burden of comorbidities, had more diagnoses of ST-elevation myocardial infarction, cardiac arrest, or cardiogenic shock, and had higher Sequential Organ Failure Assessment scores. The unadjusted in-hospital mortality (median, 12.7%) was 9.6%, 11.1%, and 18.7% in low, intermediate, and high CCRx tertiles, respectively. No clinically meaningful differences in adjusted mortality were observed across tertiles when admissions were stratified by the provision of CCRx. Baseline patient-level variables and institutional differences accounted for 80% and 5.3% of the observed CCRx variability, respectively. CONCLUSIONS: In a large registry of tertiary and academic CICUs, there was a >4-fold interhospital variation in the provision of CCRx that was primarily driven by differences in patient acuity compared with institutional differences. No differences were observed in adjusted mortality between low, intermediate, and high CCRx utilization sites.

RESUMO

BACKGROUND: Systemic anticoagulation for stroke prevention in patients with atrial fibrillation (AF) carries inherent bleeding risks, and determining whether and when to resume anticoagulation after significant bleeding is a common dilemma. We aimed to describe the clinical characteristics of AF patients discharged after a bleeding event, document real-life thromboembolic prevention strategy (TPS), and analyse their associated clinical outcomes. METHODS: We retrospectively reviewed the charts of anticoagulated AF patients admitted for bleeding from 2017 to 2019. RESULTS: A total of 140 patients were included, with a mean age of 78.6 years. Four discharge groups were defined: 75 patients (53.5%) had optimal anticoagulation (OA), 37 (26.4%) had a suboptimal antithrombotic regimen (SAR; low-dose direct oral anticoagulants without dose-reduction criteria or antiplatelet therapy), 10 (7.1%) were referred for left atrial appendage occlusion (LAAO), and 18 (12.9%) left without any TPS. All-cause mortality at 2 years was high (28.6%) but not statistically different between groups (P = 0.71). Patients discharged with a TPS (OA/SAR/LAAO referral) were more likely to be readmitted for bleeding at 2 years (34% vs 0%; P = 0.002), and those discharged without a TPS had higher rates of stroke (16.6% vs 1.4%; P = 0.003). SAR yielded readmission rates for bleeding similar to resumption of OA (27% vs 34.7%; P = 0.41) but was associated with high rates of death or readmission at 2 years. CONCLUSIONS: This real-life cohort reveals that clinicians frequently downgrade or discontinue long-term thromboembolic protection after a bleeding event despite current guideline recommendations to the contrary, and downgrading resulted in bleeding risk similar to OA.

RESUMO

PURPOSE: Neurocognitive impairment is a common and debilitating complication of sickle cell disease (SCD) resulting from a combination of biological and environmental factors. The catechol-O-methyltransferase (COMT) gene modulates levels of dopamine availability in the prefrontal cortex. COMT has repeatedly been implicated in the perception of pain stimuli and frequency of pain crises in patients with SCD and is known to be associated with neurocognitive functioning in the general population. The current study aimed to examine the associations of genetic variants in COMT and neurocognitive functioning in patients with SCD. PATIENTS AND METHODS: The Sickle Cell Clinical Research and Intervention Program (SCCRIP) longitudinal cohort was used as a discovery cohort (n = 166). The genotypes for 5 SNPs (rs6269, rs4633, rs4818, rs4680, and rs165599) in COMT were extracted from whole genome sequencing data and analyzed using a dominant model. A polygenic score for COMT (PGSCOMT) integrating these 5 SNPs was analyzed as a continuous variable. The Cooperative Study of Sickle Cell Disease (CSSCD, n = 156) and the Silent Cerebral Infarction Transfusion (SIT, n = 114) Trial were used as 2 independent replication cohorts. Due to previously reported sex differences, all analyses were conducted separately in males and females. The Benjamini and Hochberg approach was used to calculate false discovery rate adjusted p-value (q-value). RESULTS: In SCCRIP, 1 out of 5 SNPs (rs165599) was associated with IQ at q<0.05 in males but not females, and 2 other SNPs (rs4633 and rs4680) were marginally associated with sustained attention at p<0.05 in males only but did not maintain at q<0.05. PGSCOMT was negatively associated with IQ and sustained attention at p<0.05 in males only. Using 3 cohorts' data, 4 out of 5 SNPs (rs6269, rs4633, rs4680, rs165599) were associated with IQ (minimum q-value = 0.0036) at q<0.05 among male participants but not female participants. The PGSCOMT was negatively associated with IQ performance among males but not females across all cohorts. CONCLUSION: Select COMT SNPs are associated with neurocognitive abilities in males with SCD. By identifying genetic predictors of neurocognitive performance in SCD, it may be possible to risk-stratify patients from a young age to guide implementation of early interventions.

RESUMO

BACKGROUND: Several two-sample Mendelian randomization studies have reported discordant results concerning the association between grip strength and cardiovascular disease, possibly due to the number of instrumental variables used, pleiotropic bias, and/ or effect modification by age and sex. METHODS: We conducted a sex- and age-stratified one-sample Mendelian randomization study in the Canadian Longitudinal Study on Aging. We investigated whether grip strength is associated with carotid intima media thickness (cIMT), a marker of vascular atherosclerosis event risk, using eighteen single nucleotide polymorphisms (SNP) identified as specifically associated with grip strength. RESULTS: A total of 20,258 participants of self-reported European ancestry were included in the analytic sample. Our Mendelian randomization findings suggest a statistically significant association between grip strength and cIMT (MR coefficient of 0.02 (95% CI: 0.01, 0.04)). We found no statistically significant differences between sexes (p-value = 0.201), or age groups [(≤ 60 years old versus >60 years old); p-value = 0.421]. CONCLUSION: This study provides evidence that grip strength is inversely associated with cIMT. Our one-sample MR study design allowed us to demonstrate that there is no evidence of heterogeneity of effects according to age group or biological sex.

RESUMO

Antiplatelet therapy (APT) is the foundation of treatment and prevention of atherothrombotic events in patients with atherosclerotic cardiovascular disease. Selecting the optimal APT strategies to reduce major adverse cardiovascular events, while balancing bleeding risk, requires ongoing review of clinical trials. Appended, the focused update of the Canadian Cardiovascular Society/Canadian Association of Interventional Cardiology guidelines for the use of APT provides recommendations on the following topics: (1) use of acetylsalicylic acid in primary prevention of atherosclerotic cardiovascular disease; (2) dual APT (DAPT) duration after percutaneous coronary intervention (PCI) in patients at high bleeding risk; (3) potent DAPT (P2Y12 inhibitor) choice in patients who present with an acute coronary syndrome (ACS) and possible DAPT de-escalation strategies after PCI; (4) choice and duration of DAPT in ACS patients who are medically treated without revascularization; (5) pretreatment with DAPT (P2Y12 inhibitor) before elective or nonelective coronary angiography; (6) perioperative and longer-term APT management in patients who require coronary artery bypass grafting surgery; and (7) use of APT in patients with atrial fibrillation who require oral anticoagulation after PCI or medically managed ACS. These recommendations are all on the basis of systematic reviews and meta-analyses conducted as part of the development of these guidelines, provided in the Supplementary Material.

RESUMO

BACKGROUND: A strategy of administering a transfusion only when the hemoglobin level falls below 7 or 8 g per deciliter has been widely adopted. However, patients with acute myocardial infarction may benefit from a higher hemoglobin level. METHODS: In this phase 3, interventional trial, we randomly assigned patients with myocardial infarction and a hemoglobin level of less than 10 g per deciliter to a restrictive transfusion strategy (hemoglobin cutoff for transfusion, 7 or 8 g per deciliter) or a liberal transfusion strategy (hemoglobin cutoff, <10 g per deciliter). The primary outcome was a composite of myocardial infarction or death at 30 days. RESULTS: A total of 3504 patients were included in the primary analysis. The mean (±SD) number of red-cell units that were transfused was 0.7±1.6 in the restrictive-strategy group and 2.5±2.3 in the liberal-strategy group. The mean hemoglobin level was 1.3 to 1.6 g per deciliter lower in the restrictive-strategy group than in the liberal-strategy group on days 1 to 3 after randomization. A primary-outcome event occurred in 295 of 1749 patients (16.9%) in the restrictive-strategy group and in 255 of 1755 patients (14.5%) in the liberal-strategy group (risk ratio modeled with multiple imputation for incomplete follow-up, 1.15; 95% confidence interval [CI], 0.99 to 1.34; P = 0.07). Death occurred in 9.9% of the patients with the restrictive strategy and in 8.3% of the patients with the liberal strategy (risk ratio, 1.19; 95% CI, 0.96 to 1.47); myocardial infarction occurred in 8.5% and 7.2% of the patients, respectively (risk ratio, 1.19; 95% CI, 0.94 to 1.49). CONCLUSIONS: In patients with acute myocardial infarction and anemia, a liberal transfusion strategy did not significantly reduce the risk of recurrent myocardial infarction or death at 30 days. However, potential harms of a restrictive transfusion strategy cannot be excluded.

RESUMO

AIMS: Invasive haemodynamic assessment with a pulmonary artery catheter is often used to guide the management of patients with cardiogenic shock (CS) and may provide important prognostic information. We aimed to assess prognostic associations and relationships to end-organ dysfunction of presenting haemodynamic parameters in CS. METHODS AND RESULTS: The Critical Care Cardiology Trials Network is an investigator-initiated multicenter registry of cardiac intensive care units (CICUs) in North America coordinated by the TIMI Study Group. Patients with CS (2018-2022) who underwent invasive haemodynamic assessment within 24 h of CICU admission were included. Associations of haemodynamic parameters with in-hospital mortality were assessed using logistic regression, and associations with presenting serum lactate were assessed using least squares means regression. Sensitivity analyses were performed excluding patients on temporary mechanical circulatory support and adjusted for vasoactive-inotropic score. Among the 3603 admissions with CS, 1473 had haemodynamic data collected within 24 h of CICU admission. The median cardiac index was 1.9 (25th-75th percentile, 1.6-2.4) L/min/m2 and mean arterial pressure (MAP) was 74 (66-86) mmHg. Parameters associated with mortality included low MAP, low systolic blood pressure, low systemic vascular resistance, elevated right atrial pressure (RAP), elevated RAP/pulmonary capillary wedge pressure ratio, and low pulmonary artery pulsatility index. These associations were generally consistent when controlling for the intensity of background pharmacologic and mechanical haemodynamic support. These parameters were also associated with higher presenting serum lactate. CONCLUSION: In a contemporary CS population, presenting haemodynamic parameters reflecting decreased systemic arterial tone and right ventricular dysfunction are associated with adverse outcomes and systemic hypoperfusion.

RESUMO

Globally, approximately 400,000 youth are diagnosed with pediatric cancer each year. Treatment-related side effects, psychosocial challenges, and frequent school absences may adversely impact learning and the education experience among these youth. Efforts to enhance interagency collaboration between health care settings and community schools are imperative to facilitate school reintegration. The Standards for the Psychosocial Care of Children with Cancer and Their Families outline specific guidelines related to the continuity of education for students impacted by pediatric cancer. In particular, the Academic Continuity and School Reentry Support and Monitoring and Assessment of Neuropsychological Outcomes standards of care highlighted within this article align with extant programmatic efforts for transitioning hospitalized school-aged children back into community schools. This article aims to describe systematic programmatic efforts within hospital-based psychosocial programs that are consistent with the Standards for the Psychosocial Care of Children with Cancer and Their Families, as well as interagency collaboration with community schools to support student-centered education for youth impacted by pediatric cancer. Resources for school psychologists, teachers, hospital-based programs, and others involved in student-centered education for pediatric cancer patients and survivors are presented.

RESUMO

Pain and fatigue are among the most common and impactful complications of sickle cell disease (SCD). Individuals with SCD are also more likely to have neurocognitive deficits. Previous studies have suggested that pain and fatigue might influence neurocognitive functioning in patients with SCD. However, these studies are limited by small sample sizes and inadequate measurement of cognitive performance. The present study aimed to investigate the relationship between pain and fatigue with neurocognitive functioning using performance-based measures of neurocognition. Pain and fatigue were not associated with neurocognitive performance. Implications and directions for future research are discussed.

RESUMO

Background: Adherence to guidelines is associated with better patient outcomes. Although studies show suboptimal adherence to cardiovascular prevention guidelines among general practitioners, adherence among specialist physicians is understudied. The aim of this analysis was to identify practice gaps among cardiologists in a tertiary academic centre. Methods: We retrospectively audited cardiology outpatient clinic notes taken at the Cardiology Clinic at the Centre hospitalier de l'Université de Montréal (CHUM), from the period January 1, 2019 to February 28, 2019. Data were abstracted from hospital medical records. The primary outcome of interest was the rate of adherence to cardiovascular prevention guidelines. We compared the chart-documented practice at our centre to the Canadian hypertension, lipid, diabetes, antiplatelet, and heart failure guidelines in effect at the time of the audit. We also collected information regarding discussions of smoking, alcohol consumption, physical activity, and diet. Results: A total of 2503 patients were included, with a mean age of 65.6 ± 14.5 years. Dyslipidemia occurred in 63% of patients, hypertension in 55%, and coronary artery disease in 41%. Optimal low-density lipoprotein control was documented as having been achieved in just 39% of cases. Blood pressure control was adequate for 65% of patients, and glycemic control was achieved in 47% of patients with diabetes. Heart failure treatment was optimal in 34% of patients. Nearly all patients with coronary artery disease (95%) had appropriate antithrombotic therapy. The incidence of discussion of nonpharmacologic interventions varied, ranging from 91% (smoking) to 16% (diet). Conclusions: Primary and secondary prevention of cardiovascular events was found to be suboptimal in an academic tertiary-care outpatient cardiology clinic and may be representative of similar shortcomings nationwide. Strategies to ensure guideline adherence are needed.


Contexte: Le respect des lignes directrices est associé à de meilleurs résultats pour les patients. Bien que les études montrent que les omnipraticiens adhèrent de façon sous-optimale aux lignes directrices en matière de prévention des événements cardiovasculaires, l'observance chez les médecins spécialistes n'a pas été assez étudiée. Notre analyse a pour objectif de déceler les lacunes dans la pratique des cardiologues exerçant dans des centres universitaires de soins tertiaires. Méthodologie: Nous avons examiné de manière rétrospective les notes cliniques consignées au dossier des patients du Centre cardiovasculaire du Centre hospitalier de l'Université de Montréal (CHUM) et résumé les données issues des consultations ayant eu lieu du 1er janvier au 28 février 2019. Le principal résultat d'intérêt était le taux d'adhésion aux lignes directrices en matière de prévention des événements cardiovasculaires. Nous avons comparé les pratiques enregistrées dans les dossiers de notre centre aux lignes directrices canadiennes sur la prise en charge de l'hypertension, de la lipidémie, du diabète, du traitement antiplaquettaire et de l'insuffisance cardiaque en place au moment de l'évaluation. Nous avons aussi recueilli de l'information sur les discussions entourant le tabagisme, la consommation d'alcool, l'activité physique et l'alimentation. Résultats: Les données de 2 503 patients, âgés en moyenne de 65,6 ± 14,5 ans, ont été retenues. De ces patients, 63 % présentaient une dyslipidémie, 55 %, une hypertension et 41 %, une maladie coronarienne. Le taux de lipoprotéines de basse densité n'était maîtrisé de façon optimale que dans 39 % des cas. La normalisation de la pression artérielle était adéquate chez 65 % des patients, et 47 % des patients diabétiques atteignaient les cibles glycémiques. L'insuffisance cardiaque était optimalement traitée chez 34 % des patients. Presque tous les patients atteints de maladie coronarienne (95 %) recevaient un traitement antithrombotique approprié. La fréquence des discussions sur les interventions non pharmacologiques variait, allant de 91 % dans le cas du tabagisme à 16 % dans celui de l'alimentation. Conclusions: La prévention primaire et secondaire des événements cardiovasculaires s'est révélée sous-optimale dans une clinique externe de cardiologie d'un hôpital universitaire et pourrait être représentative de lacunes similaires dans l'ensemble du pays. Des stratégies visant à assurer le respect des lignes directrices sont nécessaires.

RESUMO

It is increasingly recognized that strong geographic variations in cardiovascular risk cannot be explained using traditional cardiovascular risk factors alone. Indeed, it is highly unlikely that heredity and classic risk factors such as hypertension, diabetes, dyslipidemia, and tobacco use can explain the tenfold variation observed in cardiovascular mortality among men in Russia and those in Switzerland. Since the advent of industrialization and resultant changes to our climate, it is now clear that environmental stressors also influence cardiovascular health and our thinking around cardiovascular risk prediction is in need of a paradigm shift. Herein, we review the basis for this shift in our understanding of the interplay of environmental factors with cardiovascular health. We illustrate how air pollution, hyperprocessed foods, the amount of green space, and population activity levels are now considered the 4 major environmental determinants of cardiovascular health and provide a framework for how these considerations might be incorporated into clinical risk assessment. We also outline the clinical and socioeconomic effects of the environment on cardiovascular health and review key recommendations from major medical societies.
