Prevalence and patterns of gender disparity in workplace violence among healthcare workers during the COVID-19 pandemic: a systematic review and meta-analysis.

OBJECTIVES: Despite the critical value of healthcare workers (HCWs) demonstrated during the COVID-19 pandemic, there remains a noted global surge in violence against this population. The present meta-analysis aimed to gather data on the prevalence of workplace violence (WPV) against HCWs and to determine if there is any difference based on gender. STUDY DESIGN: This was a systematic review and meta-analysis. METHODS: A thorough search of PubMed/MEDLINE, Lilacs, and Cochrane Collaboration databases was conducted from the start of the COVID-19 pandemic until March 8, 2023. Two authors independently carried out screening, data extraction, and quality assessment, followed by statistical analysis using random-effects meta-analysis and subgroup analysis to assess heterogeneity. RESULTS: We included 22 studies with 44,357 participants, of which 79.37% were women. The analysis revealed an overall prevalence of WPV similar in both women (51.86%, 95% confidence interval [CI]: 41.39-62.33) and men (51.45%, 95% CI: 40.95-61.95). There were considerable differences in gender-based WPV across geographic regions. Aggressions tend to be higher toward men in Asia (odds ratio [OR] 0.79, 95% CI 0.74-0.85, P < 0.001). Conversely, in Latin America, WPV prevalence was higher in women (OR 1.20, 95% CI 1.01-1.4, P = 0.035). HCWs from low- middle-income-level countries suffered a higher incidence of violence irrespective of gender compared with high- and upper-middle-income countries (72.36% vs 47.35%). CONCLUSIONS: Our data indicate that more than half of HCWs experienced WPV during the COVID-19 pandemic. In addition, women and HCWs in low-middle-income countries were notably vulnerable to WPV. A deeper understanding of the nuances behind violence against HCWs will help to facilitate tailored strategies for different demographical contexts. REGISTRATION: PROSPERO ID: CRD42023403970.

Gender differences in workplace violence against physicians and nurses in Latin America: a survey from the Interamerican Society of Cardiology.

OBJECTIVES: To evaluate gender differences in workplace violence (WPV) against physicians and nurses in Latin America. STUDY DESIGN: Cross-sectional study. METHODS: A cross-sectional electronic survey was conducted between January 11 and February 28, 2022. A prespecified gender analysis was performed. RESULTS: Among the 3056 responses to the electronic survey, 57% were women, 81.6% were physicians, and 18.4% were nurses. At least one act of violence was experienced by 59.2% of respondents, with verbal violence being the most common (97.5%). Women experienced more WPV than men (65.8% vs 50.4%; P < 0.001; odds ratio [OR]: 1.89; 95% confidence interval [CI]: 1.63-2.19). Women were more likely to report at least one episode of WPV per week (19.2% vs 11.9%, P < 0.001), to request for psychological help (14.5% vs 9%, P = 0.001) and to experience more psychosomatic symptoms. In addition, women were more likely to report having considered changing their job after an aggression (57.6% vs 51.3%, P = 0.011) and even leaving their job (33% vs 25.7%, P = 0.001). In a multivariate analysis, being a woman (OR: 1.76), working in emergency departments (OR: 1.99), and with COVID-19 patients (OR: 3.3) were independently associated with more aggressive interactions, while older age (OR: 0.95) and working in a private setting (OR: 0.62) implied lower risk. CONCLUSIONS: Women are more likely to experience WPV and to report more psychosomatic symptoms after the event. Preventive measures are urgently needed, with a special focus on high-risk groups such as women.

Standardized programming to reduce the burden of inappropriate therapies in implantable cardioverter defibrillators - Single centre follow up results.

BACKGROUND: Current algorithms and device morphology templates have been proposed in current Implantable Cardioverter-Defibrillators (ICDs) to minimize inappropriate therapies (ITS), but this has not been completely successful. AIM: Assess the impact of a deliberate strategy of using an atrial lead implant with standardized parameters; based on all current ICD discriminators and technologies, on the burden of ITS. METHOD: A retrospective single-centre analysis of 250 patients with either dual chamber (DR) ICDs or biventricular ICDs (CRTDs) over a (41.9 ± 27.3) month period was performed. The incidence of ITS on all ICD and CRTD patients was chronicled after the implementation of standardized programming. RESULTS: 39 events of anti-tachycardial pacing (ATP) and/or shocks were identified in 20 patients (8% incidence rate among patients). The total number of individual therapies was 120, of which 34% were inappropriate ATP, and 36% were inappropriate shocks. 11 patients of the 250 patients received ITS (4.4%). Of the 20 patients, four had ICDs for primary prevention and 16 for a secondary prevention. All the episodes in the primary indication group were inappropriate, while seven patients (43%) of the secondary indication group experienced inappropriate therapies. CONCLUSIONS: The burden of ITS in the population of patients receiving ICDs was 4.4% in the presence of atrial leads. The proposed rationalized programming criteria seems an effective strategy to minimize the burden of inappropriate therapies and will require further validation.

Are there increased periprocedural complications with the MRI-conditional Medtronic Revo SureScan Pacing System? : A meta-analysis.

BACKGROUND: The use of magnetic resonance imaging (MRI)-conditional permanent pacemakers has increased significantly. In this meta-analysis, we examine the safety of MRI-conditional pacing systems in comparison with conventional systems. METHODS: An electronic search was performed using major databases, including studies that compared the outcomes of interest between patients receiving MRI-conditional pacemakers (MRI group) versus conventional pacemakers (control group). RESULTS: Six studies (5 retrospective and 1 prospective non-randomised) involving 2,118 adult patients were identified. The MRI-conditional pacemakers, deployed in 969 patients, were all from a single manufacturer (Medtronic Pacing System with 5086 leads). The rate of pacemaker lead dislodgement (atrial and ventricular) was significantly higher in the MRI group (3% vs. 1%, OR 2.47 (95% CI 1.26; 4.83), p = 0.008). The MRI group had a significantly higher rate of pericardial complications (2% vs. 1%, OR 4.23 (95% CI 1.18; 15.10), p = 0.03) and a numerically higher overall complication rate in comparison with the conventional group (6% vs. 3%, OR 2.02 (95% CI 0.88; 4.66), p = 0.10) but this was not statistically significant. CONCLUSIONS: In this meta-analysis, the rates of pacemaker lead dislodgement and pericardial complications were significantly higher with the Medtronic MRI-conditional pacing system.

Gender equity imbalance in electrocardiology: A call to action.

Despite the increasing number of women entering the medical profession, senior positions and academic productivity in many fields of medicine remain to be men dominated. We explored gender equity in electrocardiology as perceived by recent academic productivity and also active participation (presidencies and board constituents) in both the International Society of Electrocardiology (ISE) and the International Society for Holter and Noninvasive Electrocardiology (ISHNE). Academic productivity was measured by authorship (first and senior) in the Journal of Electrocardiology (JECG) and the Annals of Noninvasive Electrocardiology (ANE) in 2015. The percentage of women ISE and ISHNE Presidents was 5.6% and 0%, respectively. Current women board constituents for each society was 12.1% for ISE, and 9.4% for ISHNE. JECG articles published in 2015 had considerably less women compared to men for both senior (16.3%) and first (25.3%) authorship. ANE articles published in 2015 followed the same trends in gender, having less women compared to men for both senior (9.4%) and first (19.3%) authorship. There is a gender equity imbalance in the field of Electrocardiology. Identifying a gender imbalance is important for understanding reasons behind these trends, and may also help improve gender equity in Electrocardiology.

Brugada phenocopies represent some unusual clinical cases with identical characteristics to Brugada syndrome (BrS) elicited by various clinical circumstances. We report the case of a woman exhibiting "Brugada Phenocopy" during an acute anterior myocardial infarction, highlighting differential diagnosis with true BrS and discussing possible mechanisms underlying its dynamic ECG pattern.

Advanced interatrial block as a substrate of supraventricular tachyarrhythmias: a well recognized syndrome.

Interatrial blocks (IABs) are well described and accepted in the scientific community. In the last four decades major discoveries were made including its physiopathology, ECG presentation, classification and association with atrial tachyarrhythmias (advanced IAB). This article will briefly review the state of the art on the understanding of advanced IAB as an electrical substrate for atrial tachyarrhythmias as well as the future directions.

Advanced interatrial block predicts recurrence of embolic stroke of undetermined source. / El bloqueo interatrial avanzado predice recurrencia de infarto cerebral embólico de origen no determinado.

BACKGROUND: Advanced interatrial block (IAB) is an independent risk factor for ischaemic stroke. This study aimed to analyse whether advanced IAB predicts recurrence of embolic stroke of undetermined source (ESUS). METHODS: 104 patients with a confirmed diagnosis of ESUS were followed up for a median period of 15 months (interquartile range, 10-48). We recorded data on clinical variables, P-wave characteristics, and presence of IAB on the electrocardiogram. Electrocardiogram findings were interpreted by a blinded, centralised rater at (XXXX2). ESUS recurrence was the primary outcome variable. RESULTS: Median age was 47 years (range, 19-85); 50% of patients were women. IAB was detected in 36 patients (34.6%); IAB was partial in 29 cases (27.9%) and advanced in 7 (6.7%). Sixteen patients (15.4%) presented stroke recurrence; of these, 5 had partial and 4 had advanced IAB (P = .01; odds ratio [OR] = 9.44; 95% confidence interval [CI], 1.88-47.46; relative risk [RR] = 4.62; 95% CI, 2.01-10.61). Median P-wave duration was longer in patients with stroke recurrence (P = .009). The multivariate logistic regression analysis identified the following independent risk factors for stroke recurrence: advanced IAB (P < .001; OR = 10.86; 95% CI, 3.07-38.46), male sex (P = .028; OR = 4.6; 95% CI, 1.18-17.96), and age older than 50 years (P = .039; OR = 3.84; 95% CI, 1.06-13.88). In the Cox proportional hazards model, the risk variables identified were age older than 50 years (P = .002; hazard ratio, 7.04; 95% CI, 2.06-23.8) and P-wave duration (per ms) (P = .007; hazard ratio, 1.02; 95% CI, 1.01-1.04). CONCLUSIONS: Advanced IAB and age older than 50 years predict ESUS recurrence.

CONCLUSIONS: Advanced IAB and age older than 50 years predict ESUS recurrence.

Embolic stroke of undetermined source: beyond atrial fibrillation.

INTRODUCTION: Embolic stroke of undetermined source (ESUS) accounts for 25% of all cerebral infarcts; only 30% are associated with paroxysmal atrial fibrillation (AF). Various biochemical, electrocardiographic, and echocardiographic findings may suggest left atrial damage and increased risk of embolism in the absence of clinically documented AF or atrial flutter. In this review, we analyse the available evidence on atrial cardiopathy or atrial disease, its involvement in ESUS, and its identification through electrocardiographic, echocardiographic, and serum markers and its possible therapeutic implications. DEVELOPMENT: A systematic search was conducted on MEDLINE (PubMed) using the following MeSH terms: MeSH [ESUS]+[atrial cardiopathy]+[atrial fibrillation]+[interatrial block]+[treatment]. We selected what we considered to be the most useful original prospective or retrospective studies and systematic reviews. We then read the full texts of the articles and checked the references cited in each article. We analyse epidemiological and demographic variables of patients with ESUS, as well as recent evidence related to presentation and prognosis and factors associated with recurrence and mortality. We review the contribution of atrial cardiopathy diagnosis prior to the detection of AF and the clinical, electrocardiographic, and echocardiographic variables and the biochemical markers associated with its development and its potential contribution to cerebral embolism. CONCLUSIONS: The systematic search of biochemical and electrocardiographic, and echocardiographic alterations can be useful to identify ESUS patients at higher risk of recurrence.

Advances in the treatment of atrial fibrillation.

Management of atrial fibrillation (AF) has changed greatly in the past 10 years. The advent of a greater understanding of the pathophysiology of AF has resulted in major therapeutic breakthroughs, both in invasive and non-invasive strategies. New antiarrhythmic agents with fewer side effects, new anticoagulants and technical advances in ablation have changed the treatment of this condition. Molecular modification of the highly effective amiodarone, to improve safety and tolerability, has produced promising analogues such as Dronedarone. Although this drug seems less effective than amiodarone in preventing AF recurrence, the drug presented an interesting data on reduction of stroke and cardiovascular death, a novel effect that needs further investigation. New antiarrhythmics with atria selectiveness such Vernakalant, might be useful for cardioversion in AF without ventricular proarrhythmia. Dabigatran, a prodrug that directly inhibits thrombin, represents an alternative to warfarin for anticoagulant treatment in selected patients. In AF ablation, technological advances are sure to result in the necessary improvements in the safety and procedures efficacy. These technologies include ablation catheters designed to electrically isolate the pulmonary veins with improved safety, efficacy, speed, and precision and improved imaging and electrical mapping systems. Although pulmonary vein isolation remains essential for most ablation procedures, the role of substrate modification has taken on increasing importance. In this article, we review the advances in the treatment of AF, focus on the new medications and advances in invasive procedures.

[Tilt test for the evaluation of syncope of unknown origin]. / Tilt test para la evaluación del síncope de origen desconocido.

UNLABELLED: The aim of this study was to evaluate the usefulness of head up tilt testing in patients with syncope of unknown origin. Between January 1994 and September 1995, 93 patients were referred for tilt table assessment due to recurrent syncope of uncertain etiology. There were 42 men (mean age 59 years). Thirty healthy volunteers served as a control group. The specific protocol used involved an initial period of supine rest for 15'. Baseline blood pressure (BP) and heart rate (HR) were recorded. This was followed by a tilt to 80 degrees for 30', BP and HR were measured every minute during the procedure. The test was considered positive when symptoms appeared associated with one of the following responses: systolic BP decreased more than 30 mmHg (vasodepressor), bradicardia or asystolia for up to 3" (cardioinhibitory) or mixed. RESULTS: The tilt test was positive in 31 of 93 patients (33%). Seventeen patients (55%) had a vasodepressor response, 3 patients (9%) a cardioinhibitory response and 11 patients (36%) mixed responses. The clinical manifestations were 62% near syncope, 19% syncope and the other patients presented dypsnea or dizziness. The symptoms disappeared promptly after adopting the supine position. None of the 30 healthy volunteers developed symptoms. We conclude that head up tilt test is a safe and effective method for identifying a neurocardiogenic origin in a syncope of uncertain etiology.

Subclavian crush syndrome: a cause of pacemaker lead fracture.

A 48-year-old male with a symptomatic 2:1 atrio-ventricular block and a dual-chamber pacemaker, implanted one year previously, was admitted due to a syncopal episode. Pacemaker malfunction was identified as the cause of syncope. Subclavian crush syndrome was the cause of the pacemaker malfunction. Its incidence, consequences and management are discussed in this report.

Left subclavian vein occlusion after pacemaker insertion.

Subclavian vein thrombosis after pacemaker lead insertion is a well-described complication of pacemaker insertion. It is usually asymptomatic due to the presence of collateral venous flow but the clinical presentation is varied. This index case illustrates a typical clinical scenario and the value of computerised tomography (CT) in providing adequate delineation of the venous pathology.
