Barbeque Brush Bristle Ingestion.

BACKGROUND: Patients presenting to the emergency department with a possible barbeque brush bristle ingestion pose many challenges. A detailed history and oral examination is needed and the typical first line investigation involves flexible laryngoscopy for direct visualization of the bristle. Given the high rate of false negatives with laryngoscopy, further imaging may be required in patients with a high suspicion of bristle ingestion Case Reports: We report on two cases presenting to the emergency department with pain following ingestion of grilled food. In both cases imaging was required to identify and assist with the removal of the bristle. Why Should an Emergency Physician Be Aware of This? Emergency physicians should have a high index of suspicion for bristle ingestion in patients with acute onset of pain or a foreign body sensation after ingesting grilled meats. Patients may require imaging to identify bristles if physical examination and laryngoscopy is negative.

Performance of the "CCS Algorithm" in real world patients.

BACKGROUND: With the publication of the 2014 Focused Update of the Canadian Cardiovascular Society Guidelines for the Management of Atrial Fibrillation, the Canadian Cardiovascular Society Atrial Fibrillation Guidelines Committee has introduced a new triage and management algorithm; the so-called "CCS Algorithm". The CCS Algorithm is based upon expert opinion of the best available evidence; however, the CCS Algorithm has not yet been validated. Accordingly, the purpose of this study is to evaluate the performance of the CCS Algorithm in a cohort of real world patients. METHODS: We compared the CCS Algorithm with the European Society of Cardiology (ESC) Algorithm in 172 hospital inpatients who are at risk of stroke due to non-valvular atrial fibrillation in whom anticoagulant therapy was being considered. RESULTS: The CCS Algorithm and the ESC Algorithm were concordant in 170/172 patients (99% of the time). There were two patients (1%) with vascular disease, but no other thromboembolic risk factors, which were classified as requiring oral anticoagulant therapy using the ESC Algorithm, but for whom ASA was recommended by the CCS Algorithm. CONCLUSIONS: The CCS Algorithm appears to be unnecessarily complicated in so far as it does not appear to provide any additional discriminatory value above and beyond the use of the ESC Algorithm, and its use could result in under treatment of patients, specifically female patients with vascular disease, whose real risk of stroke has been understated by the Guidelines.

Can the Blaylock Risk Assessment Screening Score (BRASS) predict length of hospital stay and need for comprehensive discharge planning for patients following hip and knee replacement surgery? Predicting arthroplasty planning and stay using the BRASS.

BACKGROUND: Knee and hip arthroplasty constitutes a large percentage of hospital elective surgical procedures. The Blaylock Risk Assessment Screening Score (BRASS) was designed to identify patients in need of discharge planning. The purpose of this study was to evaluate whether the BRASS was associated with length of stay (LOS) in hospital following elective arthroplasty. METHODS: We retrospectively reviewed the charts of individuals undergoing primary elective arthroplasty for knee or hip osteoarthritis who had a documented BRASS score. RESULTS: In our study cohort of 241, both BRASS (p < 0.001) and replacement type (hip v. knee; p = 0.048) were predictive of LOS. Higher BRASS was associated with older patients (p < 0.001), higher American Society of Anesthesiologists score (p < 0.001) and longer LOS (p < 0.001). We found a specificity of 83% for a BRASS greater than 8 and a hospital stay longer than 5 days and a specificity of 92% for a BRASS greater than 10. CONCLUSION: The BRASS represents a novel and significant predictor of LOS following elective arthroplasty. Patients with higher BRASS are more likely to stay in hospital 5 days or more and should receive pre-emptive social work consultations to facilitate timely discharge planning and hospital resources.

CONTEXTE: Les arthroplasties du genou et de la hanche représentent un fort pourcentage des interventions chirurgicales non urgentes pratiquées dans les hôpitaux. Le score BRASS (Blaylock Risk Assessment Screening Score) a été conçu pour reconnaître les patients dont il faut planifier le congé de l'hôpital. Le but de la présente étude était de vérifier s'il y a un lien entre le score BRASS et la durée du séjour hospitalier (DSH) après une arthroplastie non urgente. MÉTHODES: Nous avons analysé rétrospectivement les dossiers de patients soumis à une arthroplastie primaire non urgente du genou ou de la hanche dont le score BRASS avait été documenté. RÉSULTATS: Dans la cohorte de 241 patients de notre étude, le score BRASS (p < 0,001) et le type d'arthroplastie (hanche c. genou, p = 0,048) ont été des facteurs prédicteurs de la DSH. Un score BRASS plus élevé était associé à un âge plus avancé des patients (p < 0,001), à un score plus élevé à l'échelle de l'American Society of Anesthesiologists (p < 0,001) et à une DSH plus longue (p < 0,001). Nous avons observé une spécificité de 83 % pour un score BRASS supérieur à 8 et un séjour hospitalier de plus de 5 jours, et une spécificité de 92 % pour un score BRASS supérieur à 10. CONCLUSION: Le score BRASS constitue un nouveau prédicteur important de la DSH après une arthroplastie non urgente. Les patients dont le score BRASS est plus élevé, risquent davantage de séjourner plus de 5 jours à l'hôpital et devraient bénéficier de consultations préventives auprès du personnel des Services sociaux afin de faciliter la planification des congés en temps opportun et d'assurer l'utilisation efficace des ressources hospitalières.

Identifying patients at low risk for activity-related events: the RARE Score.

PURPOSE: To prospectively assess whether the Risk of Activity Related Events (RARE) Score accurately identifies patients who are at low risk of experiencing an adverse event while exercise training at cardiac rehabilitation. METHODS: Individuals screened for entry into cardiac rehabilitation were classified as high-risk (RARE Score ≥ 4) or low-risk (RARE Score < 4) using the RARE Score. Patients were followed until program completion or withdrawal, and adverse events were documented. RESULTS: Individuals (n = 656) were eligible for analysis (high risk: n = 260; low risk: n = 396). Eleven events (1 major, 10 minor) were recorded during the study, and the overall event rate was low (1 event per 1321 patient hours of exercise training). Individuals triaged as high-risk had significantly more events than the low-risk cohort (high risk: n = 8 vs low risk: n = 3; P = .024) and were 4 times more likely to experience an adverse event (OR: 4.2; 95% CI: 1.0-20.0). More than 99% of low-risk patients were event free (negative predictive value: 99.2%; 95% CI: 98.3-99.8), while participating in exercise at cardiac rehabilitation. CONCLUSION: The RARE Score accurately identifies patients who are at low risk of experiencing adverse events during exercise training at cardiac rehabilitation. The identification of low-risk patients allows for the possibility of reduced on-site supervision and monitoring, or the provision of alternative models of cardiac rehabilitation, including community- or home-based cardiac rehabilitation programs.

High and low contact frequency cardiac rehabilitation programmes elicit similar improvements in cardiorespiratory fitness and cardiovascular risk factors.

AIM: Cardiac rehabilitation (CR) is a proven intervention that substantially improves physical health and decreases death and disability following a cardiovascular event. Traditional CR typically involves 36 on-site exercise sessions spanning a 12-week period. To date, the optimal dose of CR has yet to be determined. This study compared a high contact frequency CR programme (HCF, 34 on-site sessions) with a low contact frequency CR programme (LCF, eight on-site sessions) of equal duration (4 months). METHODS: A total of 961 low-risk cardiac patients (RARE score <4) self-selected either a HCF (n = 469) or LCF (n = 492) CR programme. Cardiorespiratory fitness and cardiovascular risk factors were measured on admission and discharge. RESULTS: Similar proportions of patients completed HCF (n = 346) and LCF (n = 351) (p = 0.398). Patients who were less fit (<8 METs) were more likely to drop out of the LCF group, while younger patients (<60 years) were more likely to drop out of the HCF group. Both groups experienced similar reductions in weight (-2.3 vs. -2.4 kg; p = 0.779) and improvements in cardiorespiratory fitness (+1.5 vs. +1.4 METs; p = 0.418). CONCLUSIONS: Patients in the LCF programme achieved equivalent results to those in the HCF programme. Certain subgroups of patients, however, may benefit from participation in a HCF programme, including those patients who are predisposed to prematurely discontinuing the programme and those patients who would benefit from increased monitoring. The LCF model can be employed as an alternative option to widen access and participation for patients who are unable to attend HCF programmes due to distance or time limitations.

Blood pressure responses to acute and chronic exercise are related in prehypertension.

PURPOSE: Aerobic exercise is recommended as a way to prevent hypertension. However, about 25% of individuals receive minimal antihypertensive benefits associated with chronic exercise training. Thus, we attempt to identify those "nonresponders" to chronic exercise on the basis of their blood pressure (BP) responses to acute exercise (single session). Our primary objective was to correlate the magnitude of BP decrease after acute exercise to the magnitude of BP reduction after chronic exercise. Our secondary objective was to examine the correlates of BP reduction after acute and chronic exercise. METHODS: Seventeen prehypertensive (120 to 139/80 to 89 mm Hg) males and females (45-60 yr old) underwent acute exercise assessments before an 8-wk walking/jogging program (four times per week, 30 min per session, 65% maximum oxygen consumption). BP, hemodynamics, HR variability, and baroreflex sensitivity were assessed before and after acute exercise and chronic training. RESULTS: BP was significantly reduced -7.2 ± 1.2/-4.2 ± 1.0 and -7.0 ± 1.4/-5.2 ± 1.2 mm Hg relative to baseline after acute (30 min at 65% maximum oxygen consumption) and chronic exercise, respectively (P < 0.01). The magnitude of change in systolic BP after acute exercise was strongly correlated with change in resting systolic BP after chronic training, r = 0.89, P < 0.01. A similar correlation was observed with diastolic BP, r = 0.75, P < 0.01. After acute exercise, significant reductions in total power (ms(2)) and baroreflex sensitivity were observed in both sexes (P < 0.01). However, after chronic exercise, only men demonstrated a significant reduction in the low-frequency-to-high-frequency ratio (-36%), P < 0.01. CONCLUSIONS: The magnitude of the acute BP-lowering with exercise may predict the extent of BP lowering after chronic training interventions in prehypertensive individuals.

Interval and continuous exercise elicit equivalent postexercise hypotension in prehypertensive men, despite differences in regulation.

Equicaloric bouts of interval (IE: 5 × 2:2 min at 85% and 40% maximal oxygen uptake) and steady state (SS: 21 min at 60% maximal oxygen uptake) exercise were performed by 13 older prehypertensive males on separate days, at equivalent times of day, to assess the influence of exercise mode on postexercise hypotension (PEH). Exercise conditions were compared with a control session. Cardiovascular measures were collected for 30 min prior to, and 60 min following exercise. PEH, as measured by mean postexercise systolic blood pressure (SBP) decrease (IE: -4 ± 6 mm Hg; SS: -3 ± 4 mm Hg; control: 4 ± 4 mm Hg), area under the SBP curve (IE: -240 ± 353 mm Hg·min; SS: -192 ± 244 mm Hg·min), and minimum SBP achieved (IE: -15 ± 7 mm Hg; SS: -13 ± 7 mm Hg), was equivalent after both conditions. Stroke volume was significantly reduced (IE: -14.6 ± 16.0 mL; SS: -10.1 ± 14.2 mL, control -1.7 ± 2.2 mL) and heart rate was significantly elevated (IE: 13 ± 8 beats·min⁻¹; SS: 7.9 ± 8 beats·min⁻¹; control: -2 ± 3 beats·min⁻¹) postexercise after both conditions. Cardiac output and total peripheral resistance were nonsignificantly decreased and increased postexercise, respectively. Baroreflex sensitivity (BRS) was reduced following IE (p < 0.05) and heart rate variability (HRV) parameters were reduced after both conditions, with IE eliciting larger and longer reductions in some indices. The results from the current study indicate that older prehypertensive adults experience similar PEH following equicaloric bouts of IE and SS exercise despite larger alterations in HRV and BRS elicited by IE.
