SummaryThe retrospective observational study surveys the relationship between development of inhibitors in the treatment of haemophilia patients and risk factors such as changing FVIII products. A total of 119 patients were included in this study, 198 changes of FVIII products were evaluated. Results: During the observation period of 12 months none of the patients developed an inhibitor, which was temporally associated with a change of FVIII products. A frequent change of FVIII products didn’t lead to an increase in inhibitor risk. The change between plasmatic and recombinant preparations could not be confirmed as a risk factor. Furthermore, no correlation between treatment regimens, severity, patient age and comorbidities of the patients could be found.

AbstractObjectivesThe aim of this study was to assess the risk of cardiopulmonary resuscitation (CPR) performed in out-of-hospital settings for chest injuries in patients with out-of-hospital cardiac arrest (OHCA).MethodsThis retrospective, observational study was conducted in an emergency critical care medical center in Japan. Non-traumatic OHCA patients transferred to the hospital from April 2013 through August 2016 were analyzed. The outcome was defined by chest injuries related to CPR, which is composite of rib fractures, sternal fractures, and pneumothoraces. A multivariate logistic regression analysis was performed to assess the independent risk factors for chest injuries related to CPR. The threshold of out-of-hospital CPR duration that increased risk of chest injuries was also assessed.ResultsA total of 472 patients were identified, of whom 233 patients sustained chest injuries. The multivariate logistic regression model showed that the independent risk factors for chest injuries were age and out-of-hospital CPR duration (age: AOR=1.06 [95% CI, 1.04 to 1.07]; out-of-hospital CPR duration: AOR=1.03 [95% CI, 1.01 to 1.05]). In-hospital CPR duration was not an independent risk factor for chest injuries. When the duration of out-of-hospital CPR extended over 15 minutes, the likelihood of chest injuries increased; however, this association was not statistically significant.ConclusionsLong duration of out-of-hospital CPR was an independent risk factor for chest injuries, possibly due to the difficulty of maintaining adequate quality of CPR. Further investigations to assess the efficacy of alternative CPR devices are expected in cases requiring long transportation times.TakayamaW, KoguchiH, EndoA, OtomoY.

Abstract Background: Loss of muscle mass occurs rapidly during critical illness. It can often lead to weakness and fatigue, and it negatively affects quality of life. Despite the importance of understanding the incidence of clinically significant muscle wasting in critically ill patients, there have been few reports on this subject. This study aimed to assess the incidence of and identify risk factors associated with clinically significant loss of muscle mass in this patient population. Methods: This was a single-center observational study. Informed consent was obtained from all patients. We used ultrasound to determine the rectus femoris cross-sectional area (RFcsa) of each patient on their first and seventh days of treatment in the intensive care unit (ICU). The primary outcome of the study was the incidence of significant muscle wasting, which was defined as a greater or equal to 10% reduction in RFcsa from day 1 to day 7. SOFA score on day 7, length of artificial ventilation, ICU length of stay and twenty-eight-day mortality were evaluated as secondary outcomes. We used a logistic regression model to determine whether patient age, sex, BMI, frailty score, or medical history were significant risk factors for muscle wasting.Results: We screened an initial cohort of 1,293 patients and recruited 186 as study participants. Ultrasound measurements were completed in 104 patients. Sixty-two of these patients (59.6%) showed ≥10% decreases in RFcsa. Logistic regression analysis identified patient age as the sole risk factor associated with significant muscle wasting. While we detected no statistically significant differences associated with the secondary outcomes, the 28-day mortality rate almost doubled in the group of patients with significant wasting (30.6% versus 16.7%; p=0.165).Conclusions: Clinically significant muscle wasting was frequently observed in our cohort of critically ill adult patients. Patient age was identified as a risk factor for muscle wasting. The results of this study could be used to plan future studies that evaluate strategies to prevent muscle wasting and to improve the outcomes of critically ill patients.Trial registration: clinicaltrials.gov, NCT 03865095, date of registration: March 6, 2019.

e11550 Background: Trastuzumab is effective in the treatment of HER-2 positive breast cancer. Although clinical trials have shown an increased risk of cardiotoxicity associated with trastuzumab, this risk has not been well studied in the non-trial setting. This study aims to examine (1) the incidence of cardiotoxicity associated with trastuzumab in the clinical setting (2) the relationship, if any, between risk factors and incidence of cardiotoxicity and (3) cardiac monitoring practices. Methods: A retrospective chart review was conducted of all patients receiving adjuvant trastuzumab therapy between August 2005 and May 2008, at a Canadian academic centre. The incidence of cardiotoxicity, defined as a significant reduction in left ventricular ejection fraction (drop of >10% leading to an ejection fraction of <50%) and/or New York Heart Association class III-IV CHF symptoms requiring trastuzumab delay or discontinuation was evaluated. Medical charts and patient surveys provided demographics, risk factors and cardiac toxicity for each patient. Results: 183 patients were included in the study. The average age of participating patients was 54.8 years and 51% of participants had node positive cancer. 72% were treated sequentially with Trastuzumab and 88% received anthracyclines. The incidence of cardiotoxicity was 6.0% (n=11). Upon univariate analysis, patient age was found to be the only variable significantly associated with the occurrence of cardiotoxicity (OR: 3.55, 95% CI 1.76–90.0). Left ventricular function was monitored by serial MUGA scan every 3.35 ±1.89 months as compared to the 3 month gold standard in clinical trials. Conclusions: In this study the incidence of cardiotoxicity was 6.0%. Patient age was the only significant variable associated with cardiotoxicity, as expected from previous studies. Clinically, this suggests that older patients may need more frequent monitoring for cardiac dysfunction via MUGA and/or ECHO scans. Future research needs to address the relationship between treatment regimens and the incidence of cardiotoxicity. Furthermore, we need to better define cardiotoxicity and the clinical significance of cardiac related symptoms. No significant financial relationships to disclose.

Objectives: Diabetic patients are often diagnosed with several comorbidities. The aim of the present study was to investigate the relationship between different combinations of risk factors and complications in diabetic patients. Research design and methods: We used a longitudinal, population-wide dataset of patients with hospital diagnoses and identified all patients (n = 195,575) receiving a diagnosis of diabetes in the observation period from 2003–2014. We defined nine ICD-10-codes as risk factors and 16 ICD-10 codes as complications. Using a computational algorithm, cohort patients were assigned to clusters based on the risk factors they were diagnosed with. The clusters were defined so that the patients assigned to them developed similar complications. Complication risk was quantified in terms of relative risk (RR) compared with healthy control patients. Results: We identified five clusters associated with an increased risk of complications. A combined diagnosis of arterial hypertension (aHTN) and dyslipidemia was shared by all clusters and expressed a baseline of increased risk. Additional diagnosis of (1) smoking, (2) depression, (3) liver disease, or (4) obesity made up the other four clusters and further increased the risk of complications. Cluster 9 (aHTN, dyslipidemia and depression) represented diabetic patients at high risk of angina pectoris “AP” (RR: 7.35, CI: 6.74–8.01), kidney disease (RR: 3.18, CI: 3.04–3.32), polyneuropathy (RR: 4.80, CI: 4.23–5.45), and stroke (RR: 4.32, CI: 3.95–4.71), whereas cluster 10 (aHTN, dyslipidemia and smoking) identified patients with the highest risk of AP (RR: 10.10, CI: 9.28–10.98), atherosclerosis (RR: 4.07, CI: 3.84–4.31), and loss of extremities (RR: 4.21, CI: 1.5–11.84) compared to the controls. Conclusions: A comorbidity of aHTN and dyslipidemia was shown to be associated with diabetic complications across all risk-clusters. This effect was amplified by a combination with either depression, smoking, obesity, or non-specific liver disease.

Risk Of Hemorrhage

Object A small percentage of patients will develop a completely new or de novo aneurysm after discovery of an initial aneurysm. The natural history of these lesions is unknown. The authors undertook this statistical evaluation a large cohort of patients with both ruptured and unruptured de novo aneurysms with the aim of analyzing risk factors for rupture and estimating a risk of subarachnoid hemorrhage (SAH). Methods A review of a prospectively maintained database of all aneurysm patients treated by the vascular neurosurgery service of Goodman Campbell Brain and Spine from 1976–2010 was performed. Of the 4718 patients, 611 (13%) had long-term follow-up imaging. The authors identified 27 patients (4.4%) with a total of 32 unruptured de novo aneurysms from routine surveillance imaging. They identified another 10 patients who presented with a new SAH from a de novo aneurysm after treatment of their original aneurysm. The total study group was thus 37 patients with a total of 42 de novo aneurysms. The authors then compared the 27 patients with incidentally discovered aneurysms with the 10 patients with SAH. A statistical analysis was performed, comparing the 2 groups with respect to patient and aneurysm characteristics and risk factors. Results Thirty-seven patients were identified as having true de novo aneurysms. This group had a female predominance and a high percentage of smokers. These 37 patients had a total of 42 de novo aneurysms. Ten of these 42 aneurysms hemorrhaged. De novo aneurysms in both the SAH and non-SAH group were anatomically small (< 10 mm). The estimated risk of hemorrhage over 5 years was 14.5%, higher than the expected SAH risk of small, unruptured aneurysms reported in the ISUIA (International Study of Unruptured Intracranial Aneurysms) trial. There was no statistically significant correlation between hemorrhage and any of the following risk factors: hypertension, diabetes, tobacco and alcohol use, polycystic kidney disease, or previous SAH. There was a statistically significant between-groups difference with respect to patient age, with the mean patient age being significantly older in the SAH aneurysm group than in the non-SAH group (p = 0.047). This is likely reflective of longer follow-up and discovery time, as the mean length of time between initial treatment and discovery of the de novo aneurysm was longer in the SAH group (p = 0.011). Conclusions While rare, de novo aneurysms may have a risk for SAH that is comparatively higher than the risk associated with similarly sized, small, initially discovered unruptured saccular aneurysms. The authors therefore recommend long-term follow-up for all patients with aneurysms, and they consider a more aggressive treatment strategy for de novo aneurysms than for incidentally discovered initial aneurysms.
