is a common inhabitant of the ruminant gastrointestinal tract, where it often resides asymptomatically and may be shed into the feces. More recently it was discovered that
 may be contained within the peripheral, non-mesenteric lymph nodes, where it is impervious to in-plant pathogen control interventions and may serve as a source of
-contamination of ground beef. Over the past 10 years considerable research effort has been expended at understanding how this pathogen gets to these lymph nodes, the duration of infection, and, most importantly, screening and developing potential intervention strategies that may be employed on farm prior to the animal being presented for slaughter.

Utilizing an experimental model of
 inoculation of bovine peripheral lymph nodes (PLNs), two pilot vaccine experiments were conducted to evaluate two
 vaccines
 Newport Bacterial Extract (Experiment I) and Endovac-Bovi
 (Experiment II) on preventing
 acquisition by these nodes. In Experiment I, 4 months following the in the sub-iliac and pre-scapular lymph nodes as well as when all nodes were evaluated collectively (
 = 0.04). In Experiment II, the vaccine reduced (
 = 0.03)
 prevalence in the right popliteal and tended (
 = 0.09) to decrease prevalence in both popliteal lymph nodes.

Under these experimental conditions, the data generated provide evidence of a partial vaccine effect on
 within PLNs and indicate that further research may be warranted.

Significant coagulopathy and hyperinflammation are found in patients with coronavirus disease 2019 (COVID-19). Expert consensus has recommended prophylactic anticoagulation in COVID-19 patients due to the risk of thrombo-embolism. However, the use of therapeutic anticoagulation in these patients is still a matter of debate.

We describe a patient with COVID-19 pneumonia and a clinical hyperinflammatory state. He developed early respiratory depression and required ventilation, and he subsequently developed haemodynamic instability. Point-of-care echocardiography demonstrated a right atrial thrombus and right ventricular dysfunction suggestive of acute massive pulmonary embolism. He was managed with veno-arterial extracorporeal membrane oxygenation and local thrombolysis.

Critical cases of COVID-19 pneumonia are associated with hypercoagulation, and these patients should be monitored closely for complications. Therapeutic anticoagulation may play a role in the management and prevention of thrombo-embolism.

In the ongoing pandemic of COVID-19, respiratory failure has been reported as the main cause of death in those who develop critical illness. A few cases of concurrent myocarditis have been reported, but the extent of cardiac complications with the SARS-CoV-2 strain of coronavirus is still largely unknown.

A 53-year-old man, suspected to have COVID-19 due to a new-onset cough, shortness of breath, and hypoxia, was referred to Cardiology with sudden symptomatic bradycardia. Initial rhythm analysis revealed Type 2 atrioventricular block (Mobitz II). On arrival at the coronary care unit, he was found to be in complete heart block (Type 3). Routine blood tests showed normal electrolytes and renal function, and no elevation in troponin-I levels. Echocardiography showed mild impairment in left ventricular systolic function, with no regional wall motion abnormalities or valvular lesions. He then developed high-degree AV block lasting 6.2 s, prompting the need for an urgent permanent pacemaker implantation.

Just over a third of patients with myocarditis reportedly develop a rise in cardiac troponin. Clinically suspected myocarditis can occur in the absence of a troponin rise and rarely can cause high-grade bradyarrhythmias. Myocarditis and non-specific cardiac arrhythmias have been reported in a few cases of COVID-19, but this is the first reported case of a high-grade atrioventricular conduction block with SARS-CoV-2 infection.

Heart failure (HF) patients with cardiac implantable electronic devices (CIEDs) represent an important cohort. They are at increased risk of hospitalization and mortality. We outline how remote-only management strategies, which leverage transmitted health-related data, can be used to optimize care for HF patients with a CIED during the COVID-19 pandemic.

An 82-year-old man with HF, stable on medical therapy, underwent cardiac resynchronization therapy implantation in 2016. Modern CIEDs facilitate remote monitoring by providing real-time physiological data (thoracic impedance, heart rate and rhythm, etc.). The 'Triage Heart Failure Risk Score' (Triage-HFRS), available on Medtronic CIEDs, integrates several monitored physiological parameters into a risk prediction model classifying patients as low, medium, or high risk of HF events within 30 days. In November 2019, the patient was enrolled in an innovative clinical pathway (Triage-HF Plus) whereby any 'high' Triage-HF risk status transmission prompts a phonthat can help identify individuals at elevated risk of decompensation using automated device-generated alerts.
Myocardial injury is associated with excess mortality in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections, and the mechanisms of injury are diverse. Coagulopathy associated with this infection may have unique cardiovascular implications.

We present a case of 62-year-old male who presented after experiencing syncope and cardiac arrest. Given the clinical presentation and electrocardiographic findings, there was concern for acute coronary syndrome. However, coronary angiogram did not reveal significant coronary obstruction. Due to the unclear nature of his presentation, a bedside echocardiogram was rapidly performed and was indicative of right ventricular strain. Due to these findings, a pulmonary angiogram was performed that revealed massive pulmonary embolism. He successfully underwent catheter-directed thrombolysis and, after a prolonged hospital stay, was discharged home on lifelong anticoagulation.

The impact of coronavirus disease-2019 (COVID-19) on the cardiovascular system has been prominent and multifaceted.
