Association Between Hemoglobin A1c and Development of Cardiovascular Disease in Canadian Men and Women Without Diabetes at Baseline: A Population-Based Study of 608 474 Adults. J Am Heart Assoc 2024; 13:e031095. [PMID: 38639364 DOI: 10.1161/jaha.123.031095] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/25/2023] [Accepted: 02/28/2024] [Indexed: 04/20/2024]
Abstract
BACKGROUND We examined the association between hemoglobin A1c (HbA1c) and the development of cardiovascular disease (CVD) in men and women, without diabetes or CVD at baseline. METHODS AND RESULTS This retrospective cohort study included adults aged 40 to <80 years in Alberta, Canada. Men and women were divided into categories based on a random HbA1c during a 3-year enrollment period. The primary outcome of CVD hospitalization and secondary outcome of combined CVD hospitalization/mortality were examined during a 5-year follow-up period until March 31, 2021. A total of 608 474 individuals (55.2% women) were included. Compared with HbA1c 5.0% to 5.4%, men with HbA1c of 5.5% to 5.9% had an increased risk of CVD hospitalization (adjusted hazard ratio [aHR], 1.12 [95% CI, 1.07-1.19]) whereas women did not (aHR, 1.01 [95% CI, 0.95-1.08]). Men and women with HbA1c of 6.0% to 6.4% had a 38% and 17% higher risk and men and women with HbA1c ≥6.5% had a 79% and 51% higher risk of CVD hospitalization, respectively. In addition, HbA1c of 6.0% to 6.4% and HbA1c ≥6.5% were associated with a higher risk (14% and 41%, respectively) of CVD hospitalization/death in men, but HbA1c ≥6.5% was associated with a 24% higher risk only among women. CONCLUSIONS In both men and women, HbA1c ≥6.0% was associated with an increased risk of CVD and mortality outcomes. The association between CVD and HbA1c levels of 5.5% to 5.9%, considered to be in the "normal" range, highlights the importance of optimizing cardiovascular risk profiles at all levels of glycemia, especially in men.

Abstract
AIMS Prior studies suggest that sodium-glucose cotransporter-2 inhibitors (SGLT2is) may decrease the incidence of atrial fibrillation (AF). However, it is unknown whether SGLT2i can attenuate the disease course of AF among patients with pre-existing AF and Type II diabetes mellitus (DM). In this study, our objective was to examine the association between SGLT2i prescription and arrhythmic outcomes among patients with DM and pre-existing AF. METHODS AND RESULTS We conducted a population-based cohort study of adults with DM and AF between 2014 and 2019. Using a prevalent new-user design, individuals prescribed SGLT2i were matched 1:1 to those prescribed dipeptidyl peptidase-4 inhibitors (DPP4is) based on time-conditional propensity scores. The primary endpoint was a composite of AF-related healthcare utilization (i.e. hospitalization, emergency department visits, electrical cardioversion, or catheter ablation). Secondary outcome measures included all-cause mortality, heart failure (HF) hospitalization, and ischaemic stroke or transient ischaemic attack (TIA). Cox proportional hazard models were used to examine the association of SGLT2i with the study endpoint. Among 2242 patients with DM and AF followed for an average of 3.0 years, the primary endpoint occurred in 8.7% (n = 97) of patients in the SGLT2i group vs. 10.0% (n = 112) of patients in the DPP4i group [adjusted hazard ratio 0.73 (95% confidence interval 0.55-0.96; P = 0.03)]. Sodium-glucose cotransporter-2 inhibitors were associated with significant reductions in all-cause mortality and HF hospitalization, but there was no difference in the risk of ischaemic stroke/TIA. CONCLUSION Among patients with DM and pre-existing AF, SGLT2is are associated with decreased AF-related health resource utilization and improved arrhythmic outcomes compared with DPP4is.

Sodium-glucose co-transporter-2 inhibitors are associated with kidney benefits at all degrees of albuminuria: A retrospective cohort study of adults with diabetes. Diabetes Obes Metab 2024; 26:699-709.

Abstract
AIM To estimate the real-world effectiveness of sodium-glucose co-transporter-2 inhibitors (SGLT2is) versus dipeptidyl peptidase-4 inhibitors (DPP4is) at reducing loss of kidney function and adverse kidney events in adults with varying levels of albuminuria. MATERIALS AND METHODS In this retrospective cohort study using administrative data, we matched new SGLT2i users 1:2 to DPP4i users on diabetes therapy, chronic kidney disease (CKD) stage, albuminuria and time-conditional propensity score. Albuminuria was defined by spot urine albumin or equivalent as mild, moderate or severe. Linear regression was used to model the estimated glomerular filtration rate (eGFR), and Poisson regression for a composite kidney outcome (> 40% loss of eGFR, kidney replacement therapy or death from kidney causes) and all-cause mortality. RESULTS SGLT2i users (n = 19 238, median age 57.9 years, female 40.9%) had mostly nil/mild albuminuria (70.7%). SGLT2is were associated with a 1.36 (95% CI 0.98-1.74) mL/min/1.73m2 (P < .001) acute (≤ 60 days) decline in eGFR, relative to DPP4is. Thereafter, SGLT2is were associated with 1.04 (95% CI 0.93-1.15) mL/min/1.73m2 (P < .001) less annual eGFR loss. SGLT2i users had fewer adverse kidney outcomes (incidence rate ratio [IRR] 0.58 [0.47-0.71]; P < .001), but not all-cause mortality (IRR 0.82 [0.66-1.01]; P = .06). Outcomes were similar considering only those with nil/mild albuminuria. CONCLUSIONS SGLT2is may prevent eGFR decline and reduce the risk of adverse kidney events in adults with diabetes and nil or non-severe albuminuria.

Accuracy of Static Computer- Assisted Implant Placement in Posterior Edentulous Areas with Different Levels of Tooth- Support by Novice Clinicians. THE EUROPEAN JOURNAL OF PROSTHODONTICS AND RESTORATIVE DENTISTRY 2023; 31:373-382.

Abstract
Correct implant placement is necessary for satisfactory implant restoration. Therefore, the use of surgical guide is recommended. This study evaluated the accuracy of implant placement in posterior edentulous areas with different levels of tooth-support by novice clinicians according to fully-guided (FG), pilot-guided (PG), and freehand (FH) placement protocols. A mandibular model with missing first molars was designed. On one side, the model had a bound edentulous area (BEA), and on the other side, a free end edentulous area (FEA). Fourteen clinicians new to implant dentistry participated in the study, and each clinician inserted an implant in the BEA and FEA sites for every placement protocol. Angle, vertical and maximum horizontal platform and apex deviations were measured. The FG placement was more accurate than the PG and FH placements. This was significant for BEA angle deviation, BEA and FEA maximum horizontal platform deviations, and BEA maximum horizontal apex deviation. The PG placement was significantly more accurate than the FH placement for BEA and FEA maximum horizontal platform deviations. FG shows significantly greater angle, maximum horizontal platform and maximum horizontal apex deviations at FEA than BEA. This can be attributed to reduced guide support and the possibility of guide displacement during surgery.

Abstract
Background Type 2 myocardial infarction (T2MI) occurs when myocardial oxygen demand exceeds myocardial oxygen supply. T2MIs occur more frequently and have worse outcomes compared to Type 1 myocardial infarction caused by an acute plaque rupture. No clinical trial evidence is available to guide pharmacological therapies in this high-risk population. Methods The Rivaroxaban in Type 2 Myocardial Infarction (R2MI) trial (NCT04838808) was a trainee-led, pragmatic, pilot study that randomised patients with a T2MI to either rivaroxaban 2.5 mg twice daily or placebo. The trial was stopped early due to low recruitment. Investigators explored the challenges of conducting the trial in this population. This was supplemented by a retrospective chart review of 10,000 consecutive troponin assays undertaken during the study period. Results Over a 1-year period, 276 patients with T2MI were screened for inclusion of which only 7 (2.5%) were randomised in the trial. Study investigators identified trial design and participant population factors that limited recruitment. These included: heterogeneity of patient presentation, poor clinical prognosis, and lack of dedicated non-trainee study personnel. The major limitation to recruitment was the frequency of identified exclusion criterion. The retrospective chart review identified 1715 patients with an elevated high-sensitivity troponin level, of which 916 (53%) were adjudicated to be related to T2MI. Of these, 94.5% possessed an exclusion criterion for the trial. Conclusion Patients with a T2MI are challenging to recruit into clinical trials involving oral anticoagulation. Future studies should account for only ∼1 in every 20 screened individuals being a candidate for study recruitment.

Abstract
BACKGROUND An update on the degree to which patients with type 2 diabetes in Canada achieve treatment targets is needed to document progress and identify subgroups that need attention. We sought to estimate the frequency with which patients managed in primary care met treatment targets (i.e., HbA1c ≤ 7.0%, blood pressure < 130/80 mm Hg and low-density lipoprotein cholesterol [LDL-C] < 2.00 mmol/L), guideline-based use of statins and of angiotensin-convertingenzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs), and the effects of patient age and sex. METHODS We conducted a cross-sectional study of 32 503 and 44 930 adults with diabetes in Canada on June 30, 2015, and 2020, respectively, using electronic medical record data from primary care practices across 5 provinces. We grouped achievement of diabetes targets by age and sex, and compared between groups using logistic regression with adjustment for cardiovascular comorbidities. RESULTS In 2020, target HbA1c levels were achieved for 63.8% of women and 58.9% of men. Blood pressure and LDL-C targets were achieved for 45.6% and 45.8% of women, and for 43.1% and 59.4% of men, respectively. All 3 treatment targets were achieved for 13.3% of women and 16.5% of men. Overall, 45.3% and 54.0% of women and men, respectively, used statins; 46.5% of women used ACE inhibitors or ARBs, compared with 51.9% of men. With the exception of blood pressure and HbA1c levels among women, target achievement was lower among younger patients. Achievement of the LDL-C target, statin use and ACE inhibitor or ARB use were lower among women at any age. From 2015 to 2020, target achievement increased for HbA1c, remained consistent for LDL-C and declined for blood pressure; use of statins and of ACE inhibitors or ARBs also declined. INTERPRETATION Target achievement for blood pressure and use of statins and of ACE inhibitors and ARBs declined between 2015 and 2020, and was suboptimal in all patient groups. Widespread quality improvement is needed to increase evidence-based therapy for people with diabetes.

Abstract
BACKGROUND Sodium-glucose cotransporter 2 (SGLT2) inhibitors have important kidney and cardiovascular benefits in adults with chronic kidney disease. Among adults with diabetes, we characterized the prevalence of chronic kidney disease eligible for SGLT2 inhibitor treatment, based on definitions of eligibility from trials and diabetes guidelines, and assessed the predictors of SGLT2 inhibitor use. METHODS We conducted a cross-sectional study using linked administrative data from Alberta Health in adults with diabetes (2002-2019). Chronic kidney disease was defined as an estimated glomerular filtration rate (eGFR) less than 90 mL/min/1.73 m2 with severe or greater proteinuria (trial-based definition); or eGFR less than 60 mL/min/1.73 m2 or moderate or greater proteinuria regardless of eGFR (diabetes guideline-based definition). Predictors (sociodemographic characteristics, comorbidities and health care utilization) of SGLT2 inhibitor use were identified using logistic regression. RESULTS Of 446 315 adults with diabetes, 76 630 (17.2%, guideline-based definition; 12 867 [2.9%], trial-based definition) had chronic kidney disease eligible for SGLT2 inhibitor treatment. A total of 7.1% used SGLT2 inhibitors. Older age, lower hemoglobin A1c (HbA1c) levels, female sex, lower neighbourhood income, rural residence and hospital admission were among variables associated with nonuse of SGLT2 inhibitors (adjusted odds ratios [ORs] from 0.13 [age ≥ 85 yr] to 0.92 [rural residence], p < 0.05). Family physician visits were associated with higher SGLT2 inhibitor use (adjusted OR 4.01, p < 0.001 for > 4 visits/yr). Considering all adults, both with and without diabetes, 162 012 individuals with chronic kidney disease (5% of all Alberta adults) may benefit from treatment with SGLT2 inhibitors. INTERPRETATION Many adults with chronic kidney disease would derive heart and kidney benefits from treatment with SGLT2 inhibitors but had low SGLT2 inhibitor use as of 2019. Efforts will be needed to address lower use of SGLT2 inhibitors among female, older and lower-income adults, and to enhance primary care and promote awareness of the benefits of SGLT2 inhibitors independent of glycemic control.

Abstract
Background Sodium-glucose cotransporter-2 inhibitors (SGLT2i) and glucagon-like peptide-1 receptor agonists (GLP-1RA) have shown benefits in patients with diabetes and cardiovascular disease (CVD), heart failure (HF), and chronic kidney disease (CKD). Objective We assessed benchmark outcomes (Hemoglobin A1c, LDL-C, and blood pressure), identified the prevalence of cardiorenal indications for SGLT2i and GLP-1RA, and compared prescribing rates of GLP1-RA and SGLT2i in those with and without cardiorenal indications. Methods We analyzed data from January 2018–June 2019 for 7168 patients with diabetes using electronic medical records from the Northern Alberta Primary Care Research Network, a regional network of the Canadian Primary Sentinel Surveillance Network (CPCSSN). Patients with and without cardiorenal comorbidities were compared using descriptive statistics and two proportion Z tests. Results Hemoglobin A1c ≤ 7.0% was met by 56.8%, blood pressure < 130/80 mmHg by 62.1%, LDL-C ≤ 2.0 mmol/L by 45.3% of patients. There were 4377 patients on glucose lowering medications; metformin was most common (77.7%), followed by insulin (24.6%), insulin secretagogues (23.6%), SGLT2i (19.7%), dipeptidyl peptidase-4 inhibitor (19.3%), and GLP-1RA (9.4%). A quarter of patients had cardiorenal indications for SGLT2i or GLP-1RA. Use of SGLT2i in these patients was lower than in patients without cardiorenal comorbidities (14.9% vs 21.2%, p < 0.05). GLP-1RA use in these patients was 4.6% compared with 11% in those without cardiorenal comorbidities (p < 0.05). Discussion Contrary to current evidence and recommendations, SGLT2i and GLP1-RA were less likely to be prescribed to patients with pre-existing CVD, HF, and/or CKD, revealing opportunities to improve prescribing for patients with diabetes at high-risk for worsening cardiorenal complications.

Improving incident reporting among physicians at south health campus hospital. BMJ Open Qual 2022; 11:bmjoq-2022-001945.

Abstract
Reports of adverse events and near-misses provide the opportunity to learn about latent (systems) errors. However, voluntary incident reporting systems are underused by physicians. While reports submitted by nursing staff relate to common hazards such as medication administration or falls, physicians have broader exposure to patients' entire hospital journey. Reports by physicians have the potential to uncover more serious errors that could span multiple departments and layers of personnel. Organisational safety culture thrives when all staff are represented and feel empowered to share safety concerns.At the South Health Campus (SHC) Hospital in Calgary, Alberta, Canada, the baseline proportion of physician-submitted reports within our site's Reporting and Learning System (RLS) from July 2013 to December 2016 was 1.12%. We implemented an intervention to double the proportion of physician-submitted RLS reports, using quality improvement methods.Focus groups identified lack of experience with the RLS system, lack of feedback or closure after an RLS submission, and apprehensions about disclosing the incident to the affected patient as barriers to physician submission. Accordingly, the intervention involved direct responses from physician leadership to each physician-submitted RLS report, multimedia demonstrations of efficient RLS submission to physician groups and medical learners, and linkage to materials on safe disclosures. Effectiveness was assessed using a controlled before-and-after design, comparing SHC with the rest of Calgary and with the rest of Alberta.Following the intervention, the proportion of RLS reports that were physician submitted increased to 2.65% (OR 2.42 [95% CI 1.96 to 3.02], p<0.001), sustained over the following 4 years. While an increase was observed for the rest of Calgary, it was smaller (OR 1.27 [1.15 to 1.40], p<0.001). A decrease in the odds of physician submission was observed for the rest of Alberta. Differences between sites were significant (p<0.001).Overall, we found that physician-submitted incident reports can be increased and sustained over time if submitters receive personalised feedback by a physician safety leader. At our site, reports submitted by physicians have been valuable in uncovering complex systems issues that may not have been readily apparent.

Abstract
Background
Respiratory rate (RR) is a critical vital sign that is highly relevant in patients with cardiopulmonary disorders. The implantable cardiac monitor (ICM) provides useful data pertaining to heart rhythm, but little is known up to this point regarding its potential diagnostic value in the direct measurement of respiratory parameters. The addition of respiration information could improve understanding of overall health status of heart rhythm patients with ICM.
Objective
The primary objective of this study was to evaluate the accuracy of the RR detected by an existing implanted ICM as compared to gold-standard polysomnography (PSG) measurement of respiration.
Methods
This prospective single center study enrolled 25 patients (17 male, 62.7±12.2 yesrs) with an implanted ICM and suspected sleep-disordered breathing. The ICM was custom configured with research software to collect respiration data (Fig. 1). Simultaneous, time-synchronized PSG and ICM data were evaluated in two-minute epochs episodically during the night. The offline novel prototype RR algorithm was evaluated on episodes collected by the ICM and compared against expert manual adjudicated RR from PSG by two separate investigators. The interobserver agreement was assessed using intraclass correlation coefficient (ICC). The performance of the novel algorithm was assessed using Bland-Altman analysis with 95% limits of agreement (LOA).
Results
A total of 495 epochs were graded by two independent observers, with good ICC of 0.83 (95% C.I. 0.79–0.86). Epochs free of severe sleep disordered breathing/apnea (n=363) were included in this analysis with 106 of these containing periods of hypopnea. The development and validation datasets were comprised of 235 and 128 epochs, respectively. In the development data, the mean RR was 14.99±3 breaths per minute, and the mean RR was 13.44±2 breaths per minute in the test data. Using Bland-Altman analysis, the bias for the novel prototype algorithm was only −0.13 and +0.32 breaths per minute with 95% LOA of −2.24 to +1.98 and −2.56 to +3.19 breaths per minute (Fig. 2), in the in the development and test dataset respectively.
Conclusion
The novel prototype algorithm applied to the ICM data provided accurate determination of respiratory rate as compared to gold-standard PSG data. The capability to determine respiratory rate accurately from an existing ICM platform demonstrates the potential to extend the diagnostic power of ICMs beyond heart rhythm abnormalities to address a broad range of comorbidities including breathing disorders and heart failure.

Abstract
Background:
Home blood pressure (BP) telemonitoring combined with case management leads can reduce BP in adults with hypertension. However, the benefits of telemonitoring and case management for hypertension are not well established in older (age >= 65 years) adults. Interventions that can safely improve BP control in this distinct group will be critically important, particularly given recent trials showing cardiovascular benefits of intensive BP lowering in this group, and their increased vulnerability to over-treatment-related side effects.
Methods:
Twelve-month, open-label, randomized controlled trial of community-dwelling older adults comparing home BP telemonitoring (HBPM) with pharmacist-led case management versus enhanced usual care with HBPM alone. The primary outcome was the proportion achieving age-specific systolic BP targets on 24-hour ambulatory BP monitoring (ABPM). Changes in HBPM were also examined. Logistic and linear regression were used for analyses, with adjustment for baseline BP.
Results:
Subjects randomized to intervention (n = 61) and control (n = 59) groups were mostly female (77%), with mean age of 79.5 years. The adjusted odds ratio (aOR) for ABPM BP target achievement was 1.48 (95% CI 0.87-2.52, p = 0.15). At 12 months, the mean difference in BP changes between intervention and control groups was -1.6/-1.1 for ABPM (p-value 0.26 for systolic and 0.10 for diastolic BP), and -4.9/-3.1 for HBPM (p-value 0.04 for systolic BP and 0.01 for diastolic BP), favoring the intervention. Intervention group subjects had a higher rate of systolic BP < 110 (21% vs 5%, p = 0.009), but no differences in orthostatic symptoms, syncope, non-mechanical falls, or ED visits. Adherence to HBPM declined by 12 months, with 65% of trial-completers providing all 4 of the study-driven 3-monthly HBPM series.
Conclusions:
Home BP telemonitoring and pharmacist case management did not improve achievement of target range ambulatory BP, but did reduce home BP. It was not associated with major adverse consequences. Further trials will be necessary to refine HBPM interventions, improve adherence, and determine effectiveness in older individuals more conclusively.

Abstract
OBJECTIVES Recent diabetes guidelines call for prescribing sodium-glucose cotransporter-2 inhibitors (SGLT2i) and glucagon-like peptide-1 receptor agonists (GLP-1RA) for end-organ indications (cardiovascular disease [CVD], heart failure and chronic kidney disease) and for primary prevention of CVD in adults with multiple risk factors. Our aim was to assess the effect of new guidelines on the prevalence of SGLT2i/GLP-1RA-eligible adults, and their current rates of SGLT2i/GLP-1RA use. METHODS Cross-sectional study of Canadian adults (age ≥18 years) with diabetes on June 30, 2020, using electronic medical record data from primary care practices in 5 provinces (Alberta, Manitoba, Newfoundland, Ontario and Québec). Indications were determined from comorbidities, lab values and cardiovascular risk factors. RESULTS End-organ indications were present in 34.1% of adults for SGLT2i, and in 17.1% for GLP-1RA (CVD only). Rates of SGLT2i and GLP-1RA use were only 14.0% and 4.3%, respectively, in those with end-organ indications. The majority of these individuals had glycated hemoglobin ≤7.0%. The combination of end-organ and primary prevention indications increased eligibility for SGLT2i to 62.6%, and for GLP-1RA to 59.1%. CONCLUSIONS The implications of this sizeable reclassification of adults as SGLT2i/GLP-1RA indicated on health-care budgets and cost-effectiveness requires further study. In the meantime, targeted efforts are necessary to improve SGLT2i/GLP-1RA use in those with end-organ indications that have robust evidence of cardiovascular and kidney benefit from newer agents.

Abstract
Background Recent trials comparing catheter ablation to medical therapy in patients with heart failure (HF) with symptomatic atrial fibrillation despite first-line management have demonstrated a reduction in adverse outcomes. We performed an economic evaluation to estimate the cost-utility of catheter ablation as second line therapy in patients with HF with reduced ejection fraction. Methods and Results A Markov model with health states of alive, dead, and alive with amiodarone toxicity was constructed, using the perspective of the Canadian healthcare payer. Patients in the alive states were at risk of HF and non-HF hospitalizations. Parameters were obtained from randomized trials and Alberta health system data for costs and outcomes. A lifetime time horizon was adopted, with discounting at 3.0% annually. Probabilistic and 1-way sensitivity analyses were performed. Costs are reported in 2018 Canadian dollars. A patient treated with catheter ablation experienced lifetime costs of $64 960 and 5.63 quality-adjusted life-years (QALY), compared with $49 865 and 5.18 QALYs for medical treatment. The incremental cost-effectiveness ratio was $35 360/QALY (95% CI, $21 518-77 419), with a 90% chance of being cost-effective at a willingness-to-pay threshold of $50 000/QALY. A minimum mortality reduction of 28%, or a minimum duration of benefit of >1 to 2 years was required for catheter ablation to be attractive at this threshold. Conclusions Catheter ablation is likely to be cost-effective as a second line intervention for patients with HF with symptomatic atrial fibrillation, with incremental cost-effectiveness ratio $35 360/QALY, as long as over half of the relative mortality benefit observed in extant trials is borne out in future studies.

Background
There is a lack of consensus guidelines regarding the continuation of anticoagulant therapy following cavotricuspid isthmus (CTI) ablation for typical atrial flutter. This is despite a significant number of patients developing new-onset atrial fibrillation (AF) following the procedure. Furthermore, a summary of Kaplan-Meier estimates for drug-free, arrhythmia-free survival has never been reported.
Purpose
To estimate the incidence of drug-free, new-onset AF stratified by rhythm monitoring strategy in patients undergoing CTI ablation for isolated typical atrial flutter.
Methods
PubMed, Embase and MEDLINE databases were searched to identify relevant studies. Only studies where anti-arrhythmic drugs were discontinued post-ablation and that accounted for patient censoring by reporting results in the form of time to event data were included. Data was extracted from published Kaplan-Meier curves using a digitizing software and confidence intervals for the survivor function were estimated based on the number at risk at the time point of interest. Results were pooled in a random effects model using the DerSimonian-Laird estimator.
Results
Thirteen relevant studies incorporating 1712 patients (79 % male, mean age 63.2 +/-11.2 years, LVEF 55.2 +/-10.8%) were identified. The estimated freedom from new-onset atrial fibrillation was 89.7% (95% CI: 80.3-90.1%) at 1 year and 86.2% (95% CI: 78.4-94.0%) at 2 years in patients undergoing predominantly symptom –based monitoring, 74.6% (95%CI: 67.0-82.3%) at 1 year and 69.5% (95%CI: 63.5-75.6%) at 2 years in patients undergoing regular clinic follow-up with periodic Holter monitoring and 51.4% (95% CI: 41.8-61.0%) at 1 year and 22.7% (95% CI: 8.7% - 36.6%) at 2 years in patients with implantable loop recorders.
Conclusion
With the advent of implantable loop recorders, it is apparent that most patients with isolated atrial flutter manifest new-onset AF following CTI ablation and the merits of discontinuing anticoagulation must be carefully considered in this population. Symptom-based monitoring likely severely underestimates the incidence of new-onset AF and may lead to adverse outcomes, particularly in patients with a high risk of stroke.

Background
Implantable Cardiac Monitors (ICM) provide continuous long-term heart rhythm monitoring. The new ICM BIOMONITOR III / IIIm (BM III) is provided with a single-step insertion tool.
Purpose
To report on the insertion procedure of the BM III in a large real-world patient population.
Methods
The BM III combines a low cross-section (4.5 x 8.5 mm) with an extended ICM length (77 mm, including flexible antenna). It is inserted into subcutaneous tissue with an ‘injection’ tool that forms the pocket and delivers the device in a single step. We report results of the insertion procedure from a pooled data set from the BIO|CONCEPT BM III (completed) and the BIO|MASTER BM III and BIO|STREAM-ICM (ongoing) studies.
Results
From 54 investigational sites in 11 countries, 455 insertions were reported (including 39 BM IIIm). The patients were 63 ± 16 years old, had a BMI of 27.6 ± 5.4, and 43% were women. The indications were syncope or pre-syncope (57%), cryptogenic stroke (23%), management of AF (11%) or other (9%). Insertions took 1.7 ± 1.8 minutes until removal of the insertion tool, 4.7 ± 3.4 minutes until wound closure, and 7.1 ± 5.6 minutes including wound cleaning. The wound was sutured (79%) or closed with staples (10%) or adhesive strips (10%). General anaesthesia was used in 8% of the patients and antibiotic prophylaxis in 50% (44% systemic and 6% local). Insertions took place in the catheter laboratory (62%), operating theatre (22%) or in a consultation room (16%) without specific precautional equipment.
The insertion site was parallel to the heart"s long axis (56%), parasternal (39%), in the 2nd/3rd intercostal space (3.5%), axillary (0.9%) or at the clavicula (0.7%). The device was repositioned in one case (0.2%). 13 adverse events were reported in connection to the insertion procedure. 5 cases of device pocket bleeding or hematoma occurred. In 5 further cases, the device migrated, posing the risk of extrusion, or actually extruded. Three of these cases used only adhesive strips or no wound closure at all. In two cases, an incorrect usage of the incision tool and substantial subcutaneous fatty tissue may have contributed. One device was damaged by a 200 J defibrillation shock with a shock electrode placed over the device. One patient suffered from dyspnoea, possibly due to psychogenic hyperventilation. One patient had a vasovagal syncope due to pain after an insertion with insufficient local anaesthesia. No infections were reported until the day of analysis, which was more than 30 days after insertion in 92% of all cases.
Conclusion
The new BM III was inserted in typically less than 5 minutes until wound closure. A relevant number of insertions took place in a consultation room. Prophylactic antibiotics may be unnecessary, because no pocket infections were reported, although no antibiotic prophylaxis was used in one half of all cases (N = 229). In summary, the insertion with the new tool is fast and has a low risk of complications.

Introduction
Atrial Fibrillation (AF) is the most common sustained cardiac arrhythmia affecting 1-2% of the global population, with the prevalence of AF increasing dramatically over the past two decades. Although low levels of cardiorespiratory fitness (CRF) and physical activity are predictive of cardiovascular disease onset and mortality, only recently has this emerged as a potential risk factor for AF.
Purpose
The aim of this meta-analysis was therefore to quantify the relationship between CRF, measured by a symptom limited exercise stress test, and incident AF. We hypothesised that there would be an inverse relationship between CRF and the incidence of AF.
Methods
The systematic literature review was conducted using PUBMED, MEDLINE and EMBASE databases, with seven studies meeting the inclusion criteria. A random-effects meta-analysis was then used to compare the multivariate risk estimates of the lowest CRF group from each cohort with the group of the highest CRF.
Results
Data from 206,925 individuals (55.8% males) was used for analysis with a mean age of 55 ± 2.5 years and a mean follow-up period of 10.3 ± 5 years. The total number of AF events across the studies was 19,913. The overall pooled risk of AF in the high-CRF group versus the low-CRF group showed a significant lower risk of incident AF in those with high-CRF (OR: 0.52, 95% CI, 0.44-0.605, p < 0.001). There was evidence of statistical heterogeneity between the studies (I2 = 81%, p < 0.001). AF incidence rates demonstrated an overall decline in rates across the CRF quartiles from low to high. The mean incidence rate for low-CRF was 21 ± 13.4 compared to 6.9 ± 0.7 per 1000 person-years for the high CRF group (p = 0.03).
Conclusion
There is an inverse association between a lower CRF and an increased risk of AF, with a higher level of CRF protective against AF. This study highlights that low-CRF may be an additional risk factor for AF along with already other established lifestyle-based risk factors such as obesity and hypertension. Exercise interventions should be promoted as a primary prevention strategy in those at risk of developing AF with known risk factors. Future studies are warranted to identify the mechanism(s) through which improved CRF confers a reduction in AF incidence.

Abstract
We report the cases of 3 patients with fatal, disseminated Mycobacterium chimaera infections following cardiac surgeries. Progressive neurocognitive decline and death were explained by active granulomatous encephalitis, with widespread involvement of other organs. This syndrome is clinically elusive and, thus, may have caused deaths in prior reported series.

Abstract
Abstract
Background
Ablation index (AI) and Lesion Size Index (LSI) are novel parameters that incorporates contact force, time, and power in a weighted formula. Recent studies have shown that such indices predict lesion size and durability of pulmonary vein isolation (PVI). However, the outcomes of ablation guided by indices of force-time-power, such as PV reconnections and atrial fibrillation recurrence, have not been well characterised.
Objectives
To determine the association between indices of force-time-power and acute PV reconnections, procedure and fluoroscopy time and AF recurrence in patients undergoing radiofrequency PVI.
Methods
PUBMED and EMBASE were searched using the terms "catheter ablation" AND "Ablation index" OR "Contact force" OR "Force time integral" OR "lesion size" from inception through 22 May 2019. Studies reporting the procedure time, ablation time, fluoroscopy time, and incidence of AI acute and late reconnection and AF recurrence were included.
Result
Six studies were included in this study with 530 patients, which n = 416 were paroxysmal AF and 114 non-paroxysmal AF. All procedural characteristics (procedure, radiofrequency, and fluoroscopy times) were similar between AI guided and non-AI guided ablation (p > 0.05). Two studies comparing mean PV reconnections in AI guided vs. AI Blinded. Two studies compared minimum AI in reconnected vs. non-reconnected PV segments. Acute PV segment reconnection was associated with a lower minimum AI vs. non-reconnection. In 3 studies reporting AI guided vs. AI blinded ablations, AI was associated with an increased freedom from AF after average follow-up of 12 months.
Conclusions
Radiofrequency ablation guided by AI/LSI was associated with lower acute PV reconnection rates and improved AF freedom after PVI. There was no difference in fluoroscopy, ablation or procedure time with the use of these novel parameters.

Abstract
abstract
Fifteen laboratories took part in a collaborative study to validate a method for enumerating Escherichia coli 0157:H7. The method is based on use of a hydrophobic grid membrane filter and consists of 24 h presumptive enumeration on SD-39 Agar and serological confirmation to yield a confirmed E. coli 0157:H7 count. Six food products were analyzed: pasteurized apple cider, pasteurized 2% milk, cottage cheese, cooked ground pork, raw ground beef, and frozen whole egg. The test method produced significantly higher confirmed count results than did the reference method for milk, pork, and beef. Test method results were numerically higher than but statistically equivalent to reference method results for cheese, cider, and egg. The test method produced lower repeatability and reproducibility values than did the reference method for most food/inoculation level combinations and values very similar to those of the reference method for the remaining combinations. Overall, 94% of presumptive positive isolates from the test method were confirmed serologically as E. coli 0157:H7, and 98% of these were also biochemically typical of E. coli 0157:H7 (completed test). Corresponding rates for the reference method were 69 and 98%, respectively. On the basis of the results of this collaborative study and the precollaborative study that preceded it, it is recommended that this method be adopted official first action for enumeration of E. coli 0157:H7 in meats, poultry, dairy foods, infant formula, liquid eggs, mayonnaise, and apple cider
