Nutrition and malnutrition in elderly patients
Protein-energy undernutrition is a very common problem among elderly patients. It is promoted by age-related decreases in the basal metabolic rate, physiological change in body composition, progressive dysphagia, physical and/or cognitive impairments, depression, socioeconomic factors, effects of drugs on absorption and utilization of nutrients, and other factors. Several studies suggest that nutritional support can lower the risk of adverse outcomes among undernourished elderly patients. Monitoring food intake in patients with dysphagia may be useful in deciding between oral supplementation or artificial nutrition. The decision to provide nutritional support and the route to be used will depend on the clinical conditions of the patient, the severity of the dysphagia, the expected course of any underlying diseases, and several other patient-specific considerations. In geriatric patients, the main objectives of this type of therapy are usually the maintenance of function and improvement of the quality of life
Use of the Flugelman index for identifying patients who are difficult to discharge from the hospital
Introduction: To evaluate the use of multidimensional assessment based on the Fluegelman Index (FI) to identify internal medicine patients who are likely to be difficult to discharge from the hospital. Materials and methods: Have been evaluated all patients admitted to the medical wards of the District General Hospital of Arezzo from September 1 to October 31, 2007. We collected data on age, sex, socioeconomic condition, cause of admission, comorbidity score preadmission functional status (Barthel Index), incontinence, feeding problems, length of hospitalization, condition at discharge, and type of discharge. The FI cut off for difficult discharge was > 17. Results: Of the 413 patients (mean age 80 + 11.37 years; percentage of women, 56.1%) included in the study, 109 (26.39%) had Flugelman Index > 17. These patients were significantly older than the patients with lower FIs (85 + 9.35 vs 78 + 11.58 years, p < 0.001), more likely to be admitted for pneumonia (22% vs. 4.9% of those with lower FIs; p < 0,001). They also had more comorbidity, loss of autonomy, cognitive impairment, social frailty, and nursing care needs. The subgroup with FIs>17 had significantly higher in-hospital mortality (30.28% vs 6.25%, p < 0.001), longer hospital stay (13 vs. 10 days, p < 0.05), and higher rates of discharge to nursing homes. Conclusions: Evaluation of internal medicine patients with the Flugelman Index may be helpful for identifying more critical patients likely to require longer hospitalization and to detect factors affecting the hospital stay. This information can be useful for more effective discharge planning
[Governance in a project addressing care of disabled elderly persons within the regional healthcare system of Tuscany, Italy]
Population aging and the concurrent increase of age-related chronic degenerative diseases and disability are associated with an increased proportion of elderly persons who are dependent in activities of daily living (ADL). ADL-dependent persons need continuous and long-term health and social care according to the "taking charge" rationale, in order to warrant access and continuity of care. A healthcare system needs to respond to the long-term and complex needs, such as those of disabled elderly people, by providing appropriate health and social care services in Primary Care. A Primary Health Care system is organized according to two governance levels have distinct aims but are closely inter-dependent in their operational mechanisms. The system governance is accountable for the community and individual health protection while the delivery governance is accountable for the provision of services in accordance with appropriateness, safety and economic criteria. Delivery governance can be considered "integrated governance" as a synergy exists between two decision-making systems guiding provider choices, which are corporate governance and clinical governance. The aim of this study was to analyse the abovementioned governance levels within the healthcare system in Tuscany (Italy) referring to long-term residential care for disabled elderly people. The case of excessive accesses to emergency departments from different types of Nursing Homes (NH) is used as an example to analyse different levels of responsibility involved in the management of a critical phenomenon. Suggestions for improvement in the different levels of governance for disabled elderly people are provided, in order to support institutional programming activities
Internal medicine, complexity, evidence based medicine, almost ‘‘without evidences’’
Background: Internal medicine has been defined as the specialty of the adult medical complex patients. Complexity science suggests that illness (and health) results from complex, dynamic, and unique interactions between different components of the overall system. In a patient, complexity involves the intricate entanglement of two or more systems (e.g.; body-diseases, family, socioeconomic status, therapies). Aim of the study: To evaluate the real applicability of Evidence Based Medicne (EBM) in clinical Departments of Internal Medicine and its critical perspectives. Discussion: Habitually the internist takes decisions in these situations: a) certainty (the ideal decision is adopted and the corresponding strategy follows), b) risk (the more suitable alternative selected can be the determination of the probable value or mathematical hope) and c) uncertainty, in which decisions linked to triple agents: beliefs and personal values of the doctors (I) for their patients (II) in the society (III). In the medical decisions there are often different factors that go beyond the field of technical and scientific knowledge (family, social, economic problems, etc.) and demanding an ethical analysis of the decision. Conclusions: The ‘‘evidence-based medicine’’, as other models of care, has — in itself — some limitations. ‘‘No evidence in medicine’’ matters that the postulates of the EBM are not always applicable to the real patients of Internal Medicine wards, mostly elderly, frail, complex, with comorbidities and polipharmacy, often with cognitive dysfunction and limitation of autonomy, with psycho-emotional, social and economic problems. The interacting effects of overall involved diseases/factors and their management require more complex and individualised care than simply the sum of separate guideline components. Further innovation is required to resolve the need to enhance integration of evidence with our patients’ values at the ‘‘bedside and/or clinic’’ management
Modeling medulloblastoma in vivo and with human cerebellar organoids
Medulloblastoma (MB) is the most common malignant brain tumor in children and among the subtypes, Group 3 MB has the worst outcome. Here, we perform an in vivo, patient-specific screen leading to the identification of Otx2 and c-MYC as strong Group 3 MB inducers. We validated our findings in human cerebellar organoids where Otx2/c-MYC give rise to MB-like organoids harboring a DNA methylation signature that clusters with human Group 3 tumors. Furthermore, we show that SMARCA4 is able to reduce Otx2/c-MYC tumorigenic activity in vivo and in human cerebellar organoids while SMARCA4 T910M, a mutant form found in human MB patients, inhibits the wild-type protein function. Finally, treatment with Tazemetostat, a EZH2-specific inhibitor, reduces Otx2/c-MYC tumorigenesis in ex vivo culture and human cerebellar organoids. In conclusion, human cerebellar organoids can be efficiently used to understand the role of genes found altered in cancer patients and represent a reliable tool for developing personalized therapies
