5 per cent of S equi subspecies equi from upper respiratory tract samples) and tetracycline (62.7 per cent) was also detected. Gram-negative isolates showed resistance to gentamicin, trimethoprim-sulfamethoxazole and tetracycline but susceptibility to enrofloxacin (except Pseudomonas species, where 46.2 per cent were resistant). Multiple drug resistance was detected in 1 per cent of isolates. Conclusion Resistance to first-choice antibiotics in common equine respiratory tract bacteria was noted and warrants continued monitoring of their susceptibility profiles. This can provide information to clinicians about the best empirical antimicrobial choices against certain pathogenic bacteria and help guide antibiotic stewardship efforts to converse their efficacy.Background Canine idiopathic epilepsy (IE) is characterised by recurrent seizure activity, which can appear unpredictable and uncontrollable. The purpose of this study was to investigate the potential for seizure prediction in dogs by exploring owner-perceived seizure prediction abilities and identifying owner-reported prodromal changes (long-term changes in disposition that indicate forthcoming seizures) and seizure triggers (stimuli that precipitate seizures) in dogs with IE. check details Methods This is an online, international, cross-sectional survey of 229 owners of dogs diagnosed with IE, meeting the International Veterinary Epilepsy Task Force tier I diagnostic criteria. Results Over half (59.6 per cent) of owners believed they were able to predict an upcoming seizure in their dog, of whom nearly half (45.5 per cent) were able to do so at least 30 minutes before the seizure commenced. The most common ‘seizure predictors’ were preseizure behavioural changes including increased clinginess (25.4 per cent), restlessness (23.1 per cent) and fearful behaviour (19.4 per cent). Nearly two-thirds of owners reported prodromal changes (64.9 per cent), most commonly restlessness (29.2 per cent), and nearly half (43.1 per cent) reported seizure triggers, most commonly stress (39.1 per cent). Conclusions The relatively high prevalence of owner-reported prodromal changes and seizure triggers shows promise for utilising these methods to aid seizure prediction in dogs, which could open a window of time for pre-emptive, individualised drug interventions to abort impending seizure activity.Objective Women with suspected angina without history of coronary artery disease (CAD) less frequently have flow-limiting stenosis (FL-CAD) and more often have microvascular disease, affecting predictive accuracy of stress echocardiography (SE) for detection of FL-CAD. We postulated that carotid plaque burden (CPB) assessment would improve detection of FL-CAD and risk stratification. Methods Consecutive consenting patients assessed by SE on clinical grounds for new-onset chest pain also underwent simultaneous carotid ultrasound. Patients were followed for major adverse events (MAE) all-cause mortality, non-fatal myocardial infarction and unplanned revascularisation. Carotid plaque presence and burden (CPB) were assessed. Results After a mean of 2617±469 days (range 17-3740), of 591 recruited patients, 573 (97%) outcome data (314 females) were obtainable. Despite lower pretest probability of CAD in females versus males (14.9±0.8 vs 20.5±1.3, respectively, p less then 0.0001), prevalence of myocardial ischaemia was similar (p=0.08). Females also had lower prevalence of both carotid plaque (p less then 0.0001) and FL-CAD (p less then 0.05). CPB improved the positive predictive value of SE for detection of FL-CAD (from 34.5% to 60%) in females but not in males. Absence of CPB in females with myocardial ischaemia ruled out FL-CAD in 93% versus 57% in males. CPB was the only independent predictor of MAE (p=0.012) in females, whereas in males both SE (p less then 0.0001) and CPB (p=0.003) remained significant. Conclusion In females with new-onset stable angina without a history of cardiovascular disease, CPB improved the predictive accuracy of myocardial ischaemia for flow-limiting CAD. However, CPB provided incremental risk stratification in both sexes.Ischaemic heart disease (IHD), in particular acute coronary syndrome (ACS), comprising ST-elevation myocardial infarction, non-ST-elevation myocardial infarction and unstable angina, is the leading cause of death worldwide. Age is a major predictor of adverse outcome following ACS. COVID-19 infection seems to escalate the risk in older patients with heart disease. Increasing odds of in-hospital death is associated with older age following COVID-19 infection. Importantly, it seems older patients with comorbidities such as cardiovascular disease (CVD), in particular IHD, diabetes and hypertension, are at the highest risk of mortality following COVID-19 infection. The evidence is sparse on the optimal care of older patients with ACS with lack of robust randomised controlled trials. In this setting, with the serious threat imposed by the COVID-19 pandemic in the context of rapidly evolving knowledge with much unknown, it is important to weigh the risks and benefits of treatment strategies offered to older patients. In cases where risks outweigh the benefits, it might not be an unreasonable option to treat such patients with a conservative or a palliative approach. Further evidence to elucidate whether invasive management is beneficial in older patients with ACS is required out-with the COVID-19 pandemic. Though it is hoped that the actual acute phase of COVID-19 infection will be short lived, it is vital that important clinical research is continued, given the long-term benefits of ongoing clinical research for patients with long-term conditions, including CVD. This review aimed to evaluate the challenges and the management strategies in the care of older patients presenting with ACS in the context of the COVID-19 pandemic.Cardiac paraganglioma (PGL) is a rare neuroendocrine tumour causing significant morbidity primarily due to norepinephrine secretion potentially causing severe hypertension, palpitations, lethal tachyarrhythmias, stroke and syncope. Cardiologists are faced with two clinical scenarios. The first is the elevated norepinephrine, whose actions must be properly counteracted by adrenoceptor blockade to avoid catastrophic consequences. The second is to evaluate the precise location of a cardiac PGL and its spread since compression of cardiovascular structures may result in ischaemia, angina, non-noradrenergic-induced arrhythmia, cardiac dysfunction or failure. Thus, appropriate assessment of elevated norepinephrine by its metabolite normetanephrine is a gold biochemical standard at present. Furthermore, dedicated cardiac CT, MRI and transthoracic echocardiogram are necessary for the precise anatomic information of cardiac PGL. Moreover, a cardiologist needs to be aware of advanced functional imaging using 68Ga-DOTA(0)-Tyr(3)-octreotide positron emission tomography/CT, which offers the best cardiac PGL-specific diagnostic accuracy and helps to stage and rule out metastasis, determining the next therapeutic strategies.
