Abstract
Drug repurposing has gained the attention of many in the recent years. The practice of repurposing existing drugs for new therapeutic uses helps to simplify the drug discovery process, which in turn reduces the costs and risks that are associated with de novo development. Representing biomedical data in the form of a graph is a simple and effective method to depict the underlying structure of the information. Using deep neural networks in combination with this data represents a promising approach to address drug repurposing. This paper presents BEHOR a more comprehensive version of the REDIRECTION model, which was previously presented. Both versions utilize the DISNET biomedical graph as the primary source of information, providing the model with extensive and intricate data to tackle the drug repurposing challenge. This new version's results for the reported metrics in the RepoDB test are 0.9604 for AUROC and 0.9518 for AUPRC. Additionally, a discussion is provided regarding some of the novel predictions to demonstrate the reliability of the model. The authors believe that BEHOR holds promise for generating drug repurposing hypotheses and could greatly benefit the field.

Abstract
The treatment with sacubitril/valsartan in patients suffering from chronic heart failure with reduced ejection fraction increases left ventricular ejection fraction and decreases the risk of sudden cardiac death. We conducted a retrospective analysis regarding the impact of age differences on the treatment outcome of sacubitril/valsartan in patients with chronic heart failure with reduced ejection fraction. Patients were defined as adults if ≤65 years (n = 51) and older if >65 years of age (n = 76). The incidence of ventricular arrhythmias at 1-year follow-up was comparable in both groups (30.8 vs 26.5%; p = 0.71). The mortality rate in adult patients is significantly lower as compared with older patients (2 vs 14.5%; log-rank = 0.04). Older patients may suffer remarkably more side effects than adult patients (21.1 vs 11.8%; p = 0.03).

The additive effects of type-2 diabetes on cognitive function in older adults with heart failure. Cardiol Res Pract 2012; 2012:348054. [PMID: 22701196 PMCID: PMC3371669 DOI: 10.1155/2012/348054] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/15/2012] [Accepted: 04/08/2012] [Indexed: 11/17/2022] Open
Abstract
Background. Medical comorbidity has been theorized to contribute to cognitive impairment in heart failure (HF) patients. Specifically, type-2 diabetes mellitus (T2DM), a common coexisting condition among HF patients, may be an independent predictor of cognitive impairment. Nonetheless, the relationships between T2DM and other risk factors for cognitive impairment among persons with HF are unclear. Methods. Persons with HF (N = 169, 34.3% women, age 68.57 ± 10.28 years) completed neuropsychological testing within a framework of an ongoing study. History of T2DM, along with other medical characteristics, was ascertained through a review of participants' medical charts and self-report. Results. Many participants (34.9%) had a comorbid T2DM diagnosis. After adjustment for demographic and medical characteristics, HF patients with T2DM evidenced significantly greater impairments across multiple cognitive domains than HF patients without T2DM: λ = .92, F(5, 156) = 2.82, P = .018. Post hoc tests revealed significant associations between T2DM and attention (P = .003), executive function (P = .032), and motor functioning (P = .008). Conclusion. The findings suggest additive contributions of T2DM and HF to impairments in attention, executive function, and motor function. Future work is needed to elucidate the mechanisms by which T2DM exacerbates cognitive impairment in HF.

[Prevalence and prognostic importance of riskfactors for long hospital stay within elderly patients admitted to a hospital; a clinical-empirical study]. Tijdschr Gerontol Geriatr 2010; 41:177-86.

Abstract
BACKGROUND Of elderly patients (> 70 years) admitted to a general hospital 35% suffer from loss of self-care abilities compared to the level before admission. Risk of loss of self-care ability increases with age up to 65% after tthe age of 90. In addition, for many of these patients the duration of hospitalisation is relatively long. OBJECTIVE It is important to identify in an early stage frail-elderly patients who are at risk of a relatively long hospital stay. We conducted a study of the prevalence at intake (1st of 2nd admission day) of ten clinically relevant, patient-bound risk factors for a long hospital stay among 158 patients (> 60 years), acute and planned admitted to Vlietland Hospital. In addition, the prognostic value of the dichotomous risk factors for length of hospital stay was estimated as indicator of treatment complications. The ten clinically relevant risk factors were home care, history of falling, medication (> 4), weight loss, cognitive level and functioning, self-care, psychiatric symptoms, health status and quality of life. RESULTS There was a high prevalence of risk factors; 47.5% of the elderly patients had four or more risk factors at intake. Home care and global cognitive deterioration were significant predictors of longer length of hospital stay. Furthermore, acute admission, weight loss, psychiatric symptoms and health status seemed important. The explained variance of the prognostic model was relatively small. CONCLUSION The findings in this explorative-observational study showed a high prevalence of clinically relevant, patient-bound risk factors in elderly people in a general hospital. Some risk-factors were of prognostic interest for long hospital stay, although the explained variance was relatively small. This indicates that a more comprehensive study should be designed and conducted to include other patient-bound risk factors like co-morbidity, caregiver issues and social environment. Moreover, non-patient-bound factors should be addressed like intrinsic and logistic factors within the hospital, and the quality of recuperation programmes. Understanding of these factors contributes to timely identification of elderly patients, who are at high risk of a long hospital stay. Future policy is to perform specific treatment programmes for elderly patients identified as being patients at risk. Multidisciplinary person-oriented interventions and case management focussed on risk factors and functional recovery will be provided parallel and after hospital treatment period. Comprehensive scientific research on the cost-effectiveness of such a programme has started at the end of 200oo9 in Vlietland Hospital, Schiedam.

Abstract
BACKGROUND A reduction in the relative lymphocyte count is a marker of the stress response; however, its prognostic value remains undetermined. The objective of this study was to investigate the predictive value of the relative lymphocyte count for survival in elderly patients with congestive heart failure (CHF). METHODS AND RESULTS One thousand two hundred seventy-four consecutive patients above the age of 65 years hospitalized with heart disease were enrolled in the CHF Italian Study and followed up for 3 years. Of these, 413 patients were excluded because of factors that could affect the lymphocyte count. Of the remaining 861 patients, 423 (49%) met the criteria for the diagnosis of CHF (mean age 76 +/- 7 years, 51% men), of whom 162 patients (38%) had a relative lymphocyte count < or = 20%. The 3-year all-cause mortality in patients with CHF and a relative lymphocyte count < or = 20% was 64% compared with 40% in patients with a relative lymphocyte count > 20% (P < .0001). The age- and sex-adjusted hazard ratio for death in patients with CHF and low relative lymphocyte count was 1.76 (95% confidence interval 1.34-2.32, P = .0001). After adjustment for baseline differences and variables associated with or known to affect lymphocyte count, the hazard ratio remained significantly different from 1.0 (hazard ratio 1.73, 95% confidence interval 1.21-2.48, P = .0026). CONCLUSION A low relative lymphocyte count is an independent marker of poor prognosis in elderly patients with CHF. The relative lymphocyte count is a simple, accurate, widely available, and inexpensive marker that can help to identify elderly patients with CHF who are at increased risk for mortality. The pathophysiologic mechanism of this observation remains to be determined.
