TL;DR: Oropharyngeal dysphagia should be given more importance and attention and thus be included in all standard screening protocols, treated, and regularly monitored to prevent its main complications.
Abstract: This position document has been developed by the Dysphagia Working Group, a committee of members from the European Society for Swallowing Disorders and the European Union Geriatric Medicine Society, and invited experts. It consists of 12 sections that cover all aspects of clinical management of oropharyngeal dysphagia (OD) related to geriatric medicine and discusses prevalence, quality of life, and legal and ethical issues, as well as health economics and social burden. OD constitutes impaired or uncomfortable transit of food or liquids from the oral cavity to the esophagus, and it is included in the World Health Organization’s classification of diseases. It can cause severe complications such as malnutrition, dehydration, respiratory infections, aspiration pneumonia, and increased readmissions, institutionalization, and morbimortality. OD is a prevalent and serious problem among all phenotypes of older patients as oropharyngeal swallow response is impaired in older people and can cause aspiration. Despite its prevalence and severity, OD is still underdiagnosed and untreated in many medical centers. There are several validated clinical and instrumental methods (videofluoroscopy and fiberoptic endoscopic evaluation of swallowing) to diagnose OD, and treatment is mainly based on compensatory measures, although new treatments to stimulate the oropharyngeal swallow response are under research. OD matches the definition of a geriatric syndrome as it is highly prevalent among older people, is caused by multiple factors, is associated with several comorbidities and poor prognosis, and needs a multidimensional approach to be treated. OD should be given more importance and attention and thus be included in all standard screening protocols, treated, and regularly monitored to prevent its main complications. More research is needed to develop and standardize new treatments and management protocols for older patients with OD, which is a challenging mission for our societies.

TL;DR: Intensive, systematic, tailored and planned education and support by a nurse results in an increase in patients' self-care behaviour and no significant effects were found on use of health care resources.
Abstract: Aims To test the eVect of education and support by a nurse on self-care and resource utilization in patients with heart failure. Methods A total of 179 patients (mean age 73, 58% male, NYHA III-IV) hospitalized with heart failure were evaluated prospectively. Patients were randomized to the study intervention or to ‘care as usual’. The supportive educative intervention consisted of intensive, systematic and planned education by a study nurse about the consequences of heart failure in daily life, using a standard nursing care plan developed by the researchers for older patients with heart failure. Education and support took place during the hospital stay and at a home visit within a week of discharge. Data were collected on self-care abilities, self-care behaviour, readmissions, visits to the emergency heart centre and use of other health care resources. Results Education and support from a nurse in a hospital setting and at home significantly increases self-care behaviour in patients with heart failure. Patients from both the intervention and the control group increased their self-care behaviour within 1 month of discharge, but the increase in the intervention group was significantly more after 1 month. Although self-care behaviour in both groups decreased during the following 8 months, the increase from baseline remained statistically significant in the intervention group, but not in the control group. No significant eVects on resource utilization were found. Conclusions Intensive, systematic, tailored and planned education and support by a nurse results in an increase in patients’ self-care behaviour. No significant eVects were found on use of health care resources. Additional organisational changes, such as longer follow-up and the availability of a heart failure specialist would probably enhance the eVects of education and support.

TL;DR: In a large population cohort, which provided sufficient statistical power, BP variability assessed from 24-hour ambulatory recordings did not contribute much to risk stratification over and beyond 24- hour BP.
Abstract: In previous studies, of which several were underpowered, the relation between cardiovascular outcome and blood pressure (BP) variability was inconsistent. We followed health outcomes in 8938 subjects (mean age: 53.0 years; 46.8% women) randomly recruited from 11 populations. At baseline, we assessed BP variability from the SD and average real variability in 24-hour ambulatory BP recordings. We computed standardized hazard ratios (HRs) while stratifying by cohort and adjusting for 24-hour BP and other risk factors. Over 11.3 years (median), 1242 deaths (487 cardiovascular) occurred, and 1049, 577, 421, and 457 participants experienced a fatal or nonfatal cardiovascular, cardiac, or coronary event or a stroke. Higher diastolic average real variability in 24-hour ambulatory BP recordings predicted (P0.03) total (HR: 1.14) and cardiovascular (HR: 1.21) mortality and all types of fatal combined with nonfatal end points (HR: 1.07) with the exception of cardiac and coronary events (HR: 1.02; P0.58). Higher systolic average real variability in 24-hour ambulatory BP recordings predicted (P0.05) total (HR: 1.11) and cardiovascular (HR: 1.16) mortality and all fatal combined with nonfatal end points (HR: 1.07), with the exception of cardiac and coronary events (HR: 1.03; P0.54). SD predicted only total and cardiovascular mortality. While accounting for the 24-hour BP level, average real variability in 24-hour ambulatory BP recordings added 1% to the prediction of a cardiovascular event. Sensitivity analyses considering ethnicity, sex, age, previous cardiovascular disease, antihypertensive treatment, number of BP readings per recording, or the night:day BP ratio were confirmatory. In conclusion, in a large population cohort, which provided sufficient statistical power, BP variability assessed from 24-hour ambulatory recordings did not contribute much to risk stratification over and beyond 24-hour BP.

TL;DR: An integrative view is provided on the interrelation between decreased oxidative capacity, lipotoxicity, and mitochondrial aberrations in type 2 diabetes.
Abstract: Recent evidence points toward decreased oxidative capacity and mitochondrial aberrations as a major contributor to the development of insulin resistance and type 2 diabetes. In this article we will provide an integrative view on the interrelation between decreased oxidative capacity, lipotoxicity, and mitochondrial aberrations in type 2 diabetes. Type 2 diabetes is characterized by disturbances in fatty acid metabolism and is accompanied by accumulation of fatty acids in nonadipose tissues. In metabolically active tissues, such as skeletal muscle, fatty acids are prone to so-called oxidative damage. In addition to producing energy, mitochondria are also a major source of reactive oxygen species, which can lead to lipid peroxidation. In particular, the mitochondrial matrix, which contains DNA, RNA, and numerous enzymes necessary for substrate oxidation, is sensitive to peroxide-induced oxidative damage and needs to be protected against the formation and accumulation of lipids and lipid peroxides. Recent evidence reports that mitochondrial uncoupling is involved in the protection of the mitochondrial matrix against lipid-induced mitochondrial damage. Disturbances in this protection mechanism can contribute to the development of type 2 diabetes.

TL;DR: It is demonstrated that, next to PPAR&agr;, PPAR-bgr;/&dgr;, plays a prominent role in the regulation of cardiac lipid metabolism, thereby warranting further research into the role of PPAR &bgr ;/& dgr; in cardiac disease.
Abstract: Long-chain fatty acids (FA) coordinately induce the expression of a panel of genes involved in cellular FA metabolism in cardiac muscle cells, thereby promoting their own metabolism. These effects are likely to be mediated by peroxisome proliferator-activated receptors (PPARs). Whereas the significance of PPARalpha in FA-mediated expression has been demonstrated, the role of the PPARbeta/delta and PPARgamma isoforms in cardiac lipid metabolism is unknown. To explore the involvement of each of the PPAR isoforms, neonatal rat cardiomyocytes were exposed to FA or to ligands specific for either PPARalpha (Wy-14,643), PPARbeta/delta (L-165041, GW501516), or PPARgamma (ciglitazone and rosiglitazone). Their effect on FA oxidation rate, expression of metabolic genes, and muscle-type carnitine palmitoyltransferase-1 (MCPT-1) promoter activity was determined. Consistent with the PPAR isoform expression pattern, the FA oxidation rate increased in cardiomyocytes exposed to PPARalpha and PPARbeta/delta ligands, but not to PPARgamma ligands. Likewise, the FA-mediated expression of FA-handling proteins was mimicked by PPARalpha and PPARbeta/delta, but not by PPARgamma ligands. As expected, in embryonic rat heart-derived H9c2 cells, which only express PPARbeta/delta, the FA-induced expression of genes was mimicked by the PPARbeta/delta ligand only, indicating that FA also act as ligands for the PPARbeta/delta isoform. In cardiomyocytes, MCPT-1 promoter activity was unresponsive to PPARgamma ligands. However, addition of PPARalpha and PPARbeta/delta ligands dose-dependently induced promoter activity. Collectively, the present findings demonstrate that, next to PPARalpha, PPARbeta/delta, but not PPARgamma, plays a prominent role in the regulation of cardiac lipid metabolism, thereby warranting further research into the role of PPARbeta/delta in cardiac disease.
