Structured abstract BackgroundNearly half of patients require cardiac surgery during the acute phase of infective endocarditis (IE). We describe the characteristics of patients according to the type of valve replacement (mechanical or biological), and examine whether the type of prosthesis was associated with in-hospital and 1-year mortality. Methods and Results Among 5,591 patients included in the International Collaboration on Endocarditis ProspectiveCohort Study, 1,467 patients with definite IE were operated on during the active phase and had a biological (37%) or mechanical (63%) valve replacement.Patients who received bioprostheses were older (62 vs 54 years), more often had a history of cancer (9% vs 6%), and had moderate or severe renal disease (9% vs 4%); proportion of health care-associated IE was higher (26% vs 17%); intracardiac abscesses were more frequent (30% vs 23%). In-hospital and 1-year death rates were higher in the bioprosthesis group, 20.5% vs 14.0% (p=0.0009) and 25.3% vs 16.6% (p<.0001), respectively.In multivariable analysis, mechanical prostheses were less commonly implanted in older patients (odds ratio: 0.64 for every 10 years), and in patients with a history of cancer (0.72), but were more commonly implanted in mitral position (1.60).Bioprosthesis was independently associated with 1-year mortality (hazard ratio: 1.298). ConclusionsPatients with IE who receive a biologic valve replacement have significant differences in clinical characteristics compared to patients who receive a mechanical prosthesis. Biologic valve replacement is independently associated with a higher in-hospital and 1-year mortality, a result which is possibly related to patient characteristics rather than valve dysfunction. There are limited data to support the choice of either type of prosthesis in IE. A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPT[6] The characteristics of patients receiving biological or mechanical prosthesis and the association between type of valve prosthesis and outcome are not clearly defined. Thus, the objectives of this observational study were to describe the characteristics of patients according to the type of prosthesis and to examine the relationship between prosthesis type and 1-year mortality. METHODS International Collaboration on Endocarditis -Prospective Cohort StudyA C C E P T E D M A N U S C R I P T Medicine. All patients from sites meeting criteria for participation were included in ICE-PCS. ACCEPTED MANUSCRIPTSites had to meet the following criteria: (1) minimum enrolment of 12 cases per year in a centre with access to cardiac surgery; (2) patient identification procedures in place to ensure consecutive enrolment and to minimize ascertainment bias; (3) high-quality data, including query resolution; and (4) institutional review board and/or ethics committee approval or waiver based on local standards. Patient Selection, Data Collection and OutcomesPatients were identified prospectively and consecutively enrolled in ICE-PCS if they met criteria for possible or definite I...
Older people usually present with adverse drug events (ADEs) with nonspecific symptoms such as cognitive decline, recurrent falls, reduced mobility, and/or major deterioration. The aims of this study were to assess the ADEs of patients with dementia and presenting neuropsychiatric/behavioral, and psychological symptoms in dementia (BPSD) and to categorize and identify the principal factors that allow to prevent ADEs, and separately ADEs that result in falls. To that end, a one-year prospective study in a psychogeriatric ward (July 2015 to July 2016) was performed. All patients admitted to this ward were eligible for enrolment. Patients who met any of the following criteria were excluded from the study: Patients without cognitive impairment, a length of stay under 7 days, and palliative or previous psychiatric pathology. We included 65 patients (60% women, 84.9 years ± 6.7) with mild to moderate cognitive impairment, moderate to severe functional dependence, and a high prevalence of geriatric syndromes and comorbidity. A total of 87.7% were taking five or more drugs (mean 9.0 ± 3.1). ADEs were identified during the interdisciplinary meeting and the follow up by clinical record. Sixty-eight ADEs (81.5% patients) were identified, of which 73.5% were not related to falls. From these, 80% were related to drugs of the nervous system. The Naranjo algorithm determined that 90% of ADEs were probable. The severity of the ADEs was Category E in 34 patients (68%). The number of preventable ADE according to the Schumork–Thornton test was 58%. The main ADE was drowsiness/somnolence (27.7%). ADEs related to falls represented a 26.5%. The balance between effective treatment and safety is complex in these patients. A medication review in interdisciplinary teams is an essential component to optimize safety prevention.
