Sex Hormone Status in Women With Chronic Kidney Disease: Survey of Nephrologists’ and Renal Allied Health Care Providers’ Perceptions

Background: Chronic kidney disease (CKD) in reproductive-age women is accompanied by menstrual and fertility disorders and premature menopause. Objective: We sought to determine nephrologists’ and allied health care providers’ perceptions on management of sex hormone status in women with CKD. Methods: An anonymous, Internet-based survey was sent to nephrology society members from Canada, Australia, New Zealand, and the United Kingdom, and the Canadian Association of Nephrology Nurses and Technologists (February-November 2015). We assessed reported perceptions and management of sex hormone status in women with CKD. Results: One hundred seventy-five nephrologists (21% response rate) and 121 allied health care providers (30%; 116 nurses, 5 pharmacists) responded. Sixty-eight percent of nephrologists and 46% of allied providers were between the ages of 30 and 50 years, and 38% of nephrologists and 89% of allied workers were female. Ninety-five percent of nephrologists agreed that kidney function impacts sex hormone status, although only a minority of nephrologists reported often discussing fertility (35%, female vs male nephrologists, P = .06) and menstrual irregularities with their patients (15%, female vs male nephrologists,P = .02). Transplant nephrologists reported discussing fertility more often than did nontransplant nephrologists (53% vs 30%, P = .03). Physicians were more likely to report discussing fertility (33% vs 7.5%, P < .001) and menstrual irregularities (15% vs 9%, P = .04) with patients than allied health care providers. Forty-three percent of physicians reported uncertainty about the role for postmenopausal hormone therapy in women with CKD. Conclusion: Nephrologists and allied health care providers recognize an impact of CKD on sex hormones in women but report not frequently discussing sex hormone–related issues with patients. Our international survey highlights an important knowledge gap in nephrology

External electrical and pharmacological cardioversion for atrial fibrillation, atrial flutter or atrial tachycardias:a network meta-analysis

BackgroundAtrial fibrillation (AF) is the most frequent sustained arrhythmia. Cardioversion is a rhythm control strategy torestore normal/sinus rhythm, and can be achieved through drugs (pharmacological) or a synchronized electricshock (electrical cardioversion).ObjectivesTo assess the efficacy and safety of pharmacological and electrical cardioversion for AF.Search methodsWe searched CENTRAL, MEDLINE, Embase, Conference Proceedings Citation Index-Science (CPCI-S) andthree trials registers (ClinicalTrials.gov, WHO ICTRP and ISRCTN) on 14 February 2023.Selection criteriaWe included randomised controlled trials (RCTs) at individual patient level. Patient populations were aged ≥18years with AF of any type and duration, atrial flutter or other sustained related atrial arrhythmias, not occurring asa result of reversible causes.Data collection and analysisWe used standard Cochrane methodology to collect data and performed a network meta-analysis using thestandard frequentist graph-theoretical approach using the netmeta package in R. We used GRADE to assess thequality of the evidence which we presented in in our summary of findings with a judgement on certainty. Wecalculated differences using risk ratios (RR) and 95% confidence intervals (CI) as well as ranking treatmentsusing a P-score. We assessed clinical and statistical heterogeneity and split the networks for the primaryoutcome and acute procedural success due to concerns about violating the transitivity assumption.Main resultsWe included 112 RCTs (139 records), from which we pooled data from 15,968 patients. Average age was 47 to72 years and proportion of male patients was 38%-92%.79 trials were considered high risk of bias for at least one domain, 32 had no high risk of bias domains, but hadat least one domain classified as uncertain risk, and one study was considered low risk for all domains.For paroxysmal AF (35 trials), when compared to Placebo, AA/AP BTE incremental cardioversion (RR: 2.42;95%CI 1.65 to 3.56), quinidine (RR: 2.23; 95%CI 1.49 to 3.34), ibutilide (RR: 2.00; 95%CI 1.28 to 3.12),propafenone (RR: 1.98; 95%CI 1.67 to 2.34), amiodarone (RR: 1.69; 95%CI 1.42 to 2.02), sotalol (RR: 1.58;95%CI 1.08 to 2.31) and procainamide (RR: 1.49; 95%CI 1.13 to 1.97) likely result in a large increase inmaintenance of sinus rhythm until hospital discharge or end of study follow-up (certainty of evidence: moderate).The effect size was larger for AA/AP incremental and was progressively smaller for the subsequent interventions.Despite low certainty of evidence Antazoline may result in a large increase (RR: 28.60; 95%CI 1.77 to 461.30) inthis outcome. Similarly, low certainty evidence suggests a large increase on this outcome for flecainide (RR: 2.17;95%CI 1.68 to 2.79), vernakalant (RR: 2.13; 95%CI 1.52 to 2.99), and magnesium (RR: 1.73; 95%CI 0.79 to 3.79)on this outcome.For persistent AF (26 trials), one network was created for electrical cardioversion and showed that whencompared to AP BTE incremental energy with patches, AP BTE maximum energy with patches (RR 1.35, 95%CI1.17 to 1.55) likely results in large increase and Active compression AP BTE incremental energy with patches(RR: 1.14, 95%CI 1.00 to 1.131) likely results in an increase in maintenance of sinus rhythm at hospital dischargeor end of study follow-up (certainty of evidence: high). Use of AP BTE incremental with paddles (RR: 1.03, 95%CI0.98 to 1.09; certainty of evidence: low) may lead to a little increase, and AP MDS Incremental paddles (RR: 0.95,95%CI 0.86 to 1.05; certainty of evidence: low) may lead to a little decrease in efficacy. On the other hand, APMDS incremental energy using patches (RR: 0.78, 95%CI 0.70 to 0.87), AA RBW incremental energy withpatches (RR: 0.76, 95%CI 0.66 to 0.88), AP RBW incremental energy with patches (RR: 0.76, 95%CI 0.68 to0.86), AA MDS incremental energy with patches (RR: 0.76, 95%CI 0.67 to 0.86) and AA MDS incremental energywith paddles (RR: 0.68, 95%CI 0.53 to 0.83) probably result in a decrease on this outcome when compared to APBTE incremental energy with patches (certainty of evidence: moderate). The network for pharmacologicalcardioversion showed that Bepridil (RR: 2.29, 95%CI 1.26 to 4.17) and Quindine (RR: 1.53, (95%CI 1.01 to 2.32)probably result in large increase in maintenance of sinus rhythm at hospital discharge or end of study follow-upwhen compared to amiodarone (certainty of evidence: moderate). Dofetilide (RR: 0.79, 95%CI 0.56 to 1.44),Sotalol (RR: 0.89, 95%CI 0.67 to 1.18), Propafenone (RR: 0.79, 95%CI 0.50 to 1.25) and Pilsicainide (RR: 0.39,95%CI 0.02 to 7.01) may result in a reduction of this outcome when compared to amiodarone, but certainty ofevidence is lowFor atrial flutter (14 trials) a network could be created only for antiarrhythmic drugs. Using Placebo as thecommon comparator, ibutilide (RR: 21.45, 95%CI 4.41 to 104.37), propafenone (RR: 7.15, 95%CI 1.27 to 40.10),dofetilide (RR: 6.43, 95%CI 1.38 to 29.91), and sotalol (RR: 6.39, 95%CI 1.03 to 39.78) probably result in a largeincrease in maintenance of sinus rhythm at hospital discharge or end of study follow-up (certainty of evidence:moderate), and procainamide (RR: 4.29, 95%CI 0.63 to 29.03), flecainide (RR 3.57, 95%CI 0.24 to 52.30) andvernakalant (RR: 1.18, 95%CI 0.05 to 27.37) may result in a large increase of maintenance of sinus rhythm athospital discharge or end of study follow-up at (certainty of evidence: low) All tested electrical cardioversionstrategies for atrial flutter had very high efficacy (97.9% to 100%).Mortality (14 deaths) and Stroke or systemic embolism (3 events) at 30 days was extremely low.Data on quality of life were scarce and of uncertain clinical significance. No information was available regardingheart failure readmissions. Data on duration of hospitalization was scarce, low quality, &amp; could not be pooled.Authors' conclusionsDespite the low quality of evidence, this systematic review provides important information on electrical andpharmacological strategies to help patients and physicians deal with AF and atrial flutter.Assessing the patient comorbidity profile, antiarrhythmic drug onset of action &amp; side effect profile vs. need for aphysician with experience in sedation, or anaesthetics support, for electrical cardioversion are key aspects whenchoosing the cardioversion method

Dose-limiting, adverse event-associated bradycardia with β-blocker treatment of atrial fibrillation in the GENETIC-AF trial

Background: Heart failure (HF) patients with atrial fibrillation (AF) often have conduction system disorders, which may be worsened by β-blocker therapy.Objective: In a post hoc analysis we examined the prevalence of bradycardia and its association with adverse events (AEs) and failure to achieve target dose in the GENETIC-AF trial.Methods: Patients randomized to metoprolol (n = 125) or bucindolol (n = 131) entering 24-week efficacy follow-up and receiving study medication were evaluated. Bradycardia was defined as an electrocardiogram (ECG) heart rate (HR) &lt;60 beats per minute (bpm) and severe bradycardia &lt;50 bpm.Results: Mean HR in sinus rhythm (SR) was 62.6 ± 12.5 bpm for metoprolol and 68.3 ± 11.1 bpm for bucindolol (P &lt; .0001), but in AF HRs were not different (87.5 bpm vs 89.7 bpm, respectively). Episodes per patient for bucindolol vs metoprolol were 0.82 vs 2.08 (P &lt; .001) for bradycardia and 0.24 vs 0.57 for severe bradycardia (P &lt; .001), with 98.9% of the episodes occurring in SR. Patients experiencing bradycardia had a 4.15-fold higher prevalence of study medication dose reduction (P &lt;.0001) compared to patients without bradycardia. Fewer patients receiving metoprolol were at target dose (61.7% vs 74.9% for bucindolol, P &lt; .0001) at ECG recordings, and bradycardia AEs were more prevalent in the metoprolol group (13 vs 1 for bucindolol, P = .001). On multivariate analysis of 21 candidate bradycardia predictors including presence of a device with pacing capability, bucindolol treatment was associated with the greatest degree of prevention (Zodds ratio -4.24, P &lt; .0001).Conclusion: In AF-prone HF patients bradycardia may limit the effectiveness of β blockers, and this property is agent-dependent.</p

Evaluation of optimal medical therapy in acute myocardial infarction patients with prior stroke

Background: Treatment of acute myocardial infarction (AMI) patients with prior stroke is a common clinical dilemma. Currently, the application of optimal medical therapy (OMT) and its impact on clinical outcomes are not clear in this patient population. Methods: We retrieved 765 AMI patients with prior stroke who underwent percutaneous coronary intervention (PCI) during the index hospitalization from the international multicenter BleeMACS registry. All of the subjects were divided into two groups based on the prescription they were given prior to discharge. Baseline characteristics and procedural variables were compared between the OMT and non-OMT groups. Mortality, re-AMI, major adverse cardiovascular events (MACE), and bleeding were followed-up for 1 year. Results: Approximately 5% of all patients presenting with AMI were admitted to the hospital for ischemic stroke. Although the prescription rate of each OMT medication was reasonably high (73.3%-97.3%), 47.7% lacked at least one OMT medication. Patients receiving OMT showed a significantly decreased occurrence of mortality (4.5% vs 15.1%, p < 0.001), re-AMI (4.2% vs 9.3%, p = 0.004), and the composite endpoint of death/re-AMI (8.6% vs 20.5%, p < 0.001) compared to those without OMT. No significant difference was observed between the groups regarding bleeding. After adjusting for confounding factors, OMT was the independent protective factor of 1-year mortality, while age was the independent risk factors. Conclusions: OMT at discharge was associated with a significantly lower 1-year mortality of patients with AMI and prior stroke in clinical practice. However, OMT was provided to just half of the eligible patients, leaving room for substantial improvement

Staged induction of HIV-1 glycan–dependent broadly neutralizing antibodies

A preventive HIV-1 vaccine should induce HIV-1–specific broadly neutralizing antibodies (bnAbs). However, bnAbs generally require high levels of somatic hypermutation (SHM) to acquire breadth, and current vaccine strategies have not been successful in inducing bnAbs. Because bnAbs directed against a glycosylated site adjacent to the third variable loop (V3) of the HIV-1 envelope protein require limited SHM, the V3-glycan epitope is an attractive vaccine target. By studying the cooperation among multiple V3-glycan B cell lineages and their coevolution with autologous virus throughout 5 years of infection, we identify key events in the ontogeny of a V3-glycan bnAb. Two autologous neutralizing antibody lineages selected for virus escape mutations and consequently allowed initiation and affinity maturation of a V3-glycan bnAb lineage. The nucleotide substitution required to initiate the bnAb lineage occurred at a low-probability site for activation-induced cytidine deaminase activity. Cooperation of B cell lineages and an improbable mutation critical for bnAb activity defined the necessary events leading to breadth in this V3-glycan bnAb lineage. These findings may, in part, explain why initiation of V3-glycan bnAbs is rare, and suggest an immunization strategy for inducing similar V3-glycan bnAbs

Influence of Sex-Based Differences in Cardiac Phenotype on Atrial Fibrillation Recurrence in Patients Undergoing Pulmonary Vein Isolation

BackgroundPulmonary vein isolation (PVI) is a commonly engaged therapy for symptomatic atrial fibrillation (AF). Prior studies have documented elevated AF recurrence rates among females vs. males. Sex-specific mechanisms underlying this phenomenon are poorly understood. This prospective cohort study aimed to evaluate the sex-based differences in cardiac phenotype and their influence on (AF) recurrence following first-time PVI.MethodsA total of 204 consecutive patients referred for first-time PVI and 101 healthy subjects were prospectively studied by cardiovascular magnetic resonance (CMR) imaging. Multi-chamber volumetric and functional measures were assessed by sex-corrected Z-score analyses vs. healthy subjects. Patients were followed for a median of 2.6 years for the primary outcome of clinical AF recurrence. Multivariable analyses adjusting for age and comorbidities were performed to identify independent predictors of AF recurrence.ResultsAF recurrence following first PVI occurred in 41% of males and 59% of females (p = 0.03). Females were older with higher prevalence of hypertension and thyroid disorders. Z-score-based analyses revealed significantly reduced ventricular volumes, greater left atrial (LA) volumes, and reduced LA contractility in females vs. males. Multivariable analysis revealed each of LA minimum and pre-systolic volumes and booster EF Z-scores to be independently associated with AF recurrence, providing respective hazard ratios of 1.10, 1.19, and 0.89 (p = 0.001, 0.03, and 0.01).ConclusionAmong patients referred for first time PVI, females were older and demonstrated significantly poorer LA contractile health vs. males, the latter independently associated with AF recurrence. Assessment of LA contractile health may therefore be of value to identify female patients at elevated risk of AF recurrence. Factors influencing female patient referral for PVI at more advanced stages of atrial disease warrant focused investigation

Association of Beta-Blockers with Survival on Patients Presenting with ACS Treated with PCI: A Propensity Score Analysis from the BleeMACS Registry

Purpose: The aim was to evaluate prognostic value of beta-blocker (BB) administration in acute coronary syndromes (ACS) patients in the percutaneous coronary intervention (PCI) era. Methods and Results: The BleeMACS project is a multicenter, observational, retrospective registry enrolling patients with ACS worldwide in 15 hospitals. Patients discharged with BB therapy were compared to those discharged without a BB before and after propensity score with matching. The primary endpoint was all-cause mortality at 1 year. Secondary endpoints included in-hospital reinfarction, in-hospital heart failure, 1-year myocardial infarction, 1-year bleeding and 1-year composite of death and recurrent myocardial infarction. After matching, 2935 patients for each group were enrolled. The primary endpoint of 1-year death was significantly lower in the group on BB therapy (4.5 vs 7%, p < 0.05), while only a trend was noted for recurrent acute myocardial infarction (4.5 vs 4.9%, p = 0.54). These results were consistent for patients older than 80 years of age, for ST-elevation myocardial infarction (STEMI) patients, and for those discharged with complete versus incomplete revascularization, but not for non-STEMI/unstable angina patients. Conclusions: BB therapy was related to 1-year lower risk of all-cause mortality, independently from completeness of revascularization, admission diagnosis, age and ejection fraction. Randomized controlled trials for patients treated with PCI for ACS should be performed

Prediction of Post-Discharge Bleeding in Elderly Patients with Acute Coronary Syndromes: Insights from the BleeMACS Registry

Background A poor ability of recommended risk scores for predicting in-hospital bleeding has been reported in elderly patients with acute coronary syndromes (ACS). No study assessed the prediction of post-discharge bleeding in the elderly. The new BleeMACS score (Bleeding complications in a Multicenter registry of patients discharged with diagnosis of Acute Coronary Syndrome), was designed to predict post-discharge bleeding in ACS patients. We aimed to assess the predictive ability of the BleeMACS score in elderly patients. Methods We assessed the incidence and characteristics of severe bleeding after discharge in ACS patients aged ≥ 75 years. Bleeding was defined as any intracranial bleeding or bleeding leading to hospitalization and/or red blood transfusion, occurring within the first year after discharge. We assessed the predictive ability of the BleeMACS score according to age by Fine-Gray proportional hazards regression analysis, calculating receiver-operating characteristic (ROC) curves and the area under the ROC curves (AUC). Results The BleeMACS registry included 15,401 patients of whom 3,376/15,401 (21.9%) were aged ≥ 75 years. Elderly patients were more commonly treated with clopidogrel and less often treated with ticagrelor or prasugrel. Of 3,376 elderly patients, 190 (5.6%) experienced post-discharge bleeding. The incidence of bleeding was moderately higher in elderly patients (hazard ratio [HR], 2.31, 95% confidence interval [CI], 1.92-2.77). The predictive ability of the BleeMACS score was moderately lower in elderly patients (AUC, 0.652 vs. 0.691, p = 0.001). Conclusion Elderly patients with ACS had a significantly higher incidence of post-discharge bleeding. Despite a lower predictive ability in older patients, the BleeMACS score exhibited an acceptable performance in these patients

Juxtaposing BTE and ATE – on the role of the European insurance industry in funding civil litigation

One of the ways in which legal services are financed, and indeed shaped, is through private insurance arrangement. Two contrasting types of legal expenses insurance contracts (LEI) seem to dominate in Europe: before the event (BTE) and after the event (ATE) legal expenses insurance. Notwithstanding institutional differences between different legal systems, BTE and ATE insurance arrangements may be instrumental if government policy is geared towards strengthening a market-oriented system of financing access to justice for individuals and business. At the same time, emphasizing the role of a private industry as a keeper of the gates to justice raises issues of accountability and transparency, not readily reconcilable with demands of competition. Moreover, multiple actors (clients, lawyers, courts, insurers) are involved, causing behavioural dynamics which are not easily predicted or influenced. Against this background, this paper looks into BTE and ATE arrangements by analysing the particularities of BTE and ATE arrangements currently available in some European jurisdictions and by painting a picture of their respective markets and legal contexts. This allows for some reflection on the performance of BTE and ATE providers as both financiers and keepers. Two issues emerge from the analysis that are worthy of some further reflection. Firstly, there is the problematic long-term sustainability of some ATE products. Secondly, the challenges faced by policymakers that would like to nudge consumers into voluntarily taking out BTE LEI
