Erythropoietin: effects on life expectancy in patients with cancer-related anaemia
2006
ABSTRACTAnaemia is common in patients with cancer and has a detrimental impact on the quality of life. Anaemia has also been shown to reduce survival in patients with cancer. Tumour hypoxia resulting from the reduced oxygen carrying capacity of the blood in anaemic patients has been hypothesised to be a major contributor to this reduced survival. Several studies have shown that tumour hypoxia reduces the effectiveness of anticancer therapies including standard radiotherapy and some types of chemotherapy, and is associated with tumour progression. Moreover, preclinical data have demonstrated that erythropoietic protein therapy may delay tumour progression by improving tumour oxygenation. Mos…
Genomic profile of breast cancer: costeffectiveness analysis from the Spanish National Healthcare System perspective.
2014
Background: Costeffectiveness analysis of MammaPrint® (70-gene signature) in the diagnosis of early breast cancer as a prognosis assay to study the risk of tumor recurrence to administer adjuvant chemotherapy. Methods: Markov model assuming a cohort of 60-year-old women with breast cancer. Treatment costs and effects were assessed by comparing the 5-year, 10-year and lifetime risk of recurrence using Adjuvant! Online® (online algorithm), 70-gene signature or Oncotype DX® (21-gene assay). Results: 70-gene signature showed a life expectancy of 23.55 years at lifetime. Life expectancy was lower for 21-gene assay and online algorithm, with associated quality-adjusted life year gains up to 0.23 …
Aging and Oral Health: Effects in Hard and Soft Tissues
2009
Changing demographics, including an increase in life expectancy and the growing numbers of elderly has recently focused attention on the need for geriatric dental care. Ageing affects oral tissues in addition to other parts of the human body, and oral health (including oral mucosa, lips, teeth and associated structures, and their functional activity) is an integral component of general health; indeed, oral disease can cause pain, difficulty in speaking, mastication, swallowing, maintaining a balanced diet, not to mention aesthetical considerations and facial alterations leading to anxiety and depression. The World Health Organization recommends the adoption of certain strategies for improvi…
Drosophila DJ-1 mutants are sensitive to oxidative stress and show reduced lifespan and motor deficits.
2007
Parkinson's disease (PD) is a progressive movement disorder caused by the selective and massive loss of dopaminergic neurons (DA) in the substantia nigra pars compacta (SNc). DJ-1 loss-of-function mutations are involved in inherited early-onset PD forms and result in dysfunction of the oxidative stress response. In mice models, DJ-1 loss provokes sensitivity to oxidative insults but does not produce neurodegeneration. Similar results have been found when analyzing Drosophila mutants for the DJ-1 orthologous genes, DJ-1alpha and DJ-1beta. Here, we report the analysis of two new mutations for the Drosophila DJ-1 genes. Both ubiquitous induction of DJ-1alpha knockdown by RNAi and loss of funct…
Interleukin 6 (IL-6) deficiency delays lupus nephritis in MRL-Faslpr mice: the IL-6 pathway as a new therapeutic target in treatment of autoimmune ki…
2009
Objective.To investigate the pathophysiological effect of interleukin 6 (IL-6) on lupus nephritis in MRL-Faslprmice.Methods.We generated IL-6-deficient MRL-Faslprmice using a backcross/intercross breeding scheme. Renal pathology was evaluated using immunohistochemistry detection for macrophages, lymphocytes, vascular cell adhesion molecule-1 (VCAM-1), and TUNEL (terminal deoxynucleotide transferase-mediated dUTP nick end-labeling) for apoptotic cells, and renal IgG and C3 deposition by immunofluorescence staining. Expression of inflammatory markers in the spleen was analyzed by quantitative real-time reverse transcription-polymerase chain reaction. Serum cytokine concentrations were detecte…
Global, regional, national, and selected subnational levels of stillbirths, neonatal, infant, and under-5 mortality, 1980-2015 : a systematic analysi…
2016
BACKGROUND: Established in 2000, Millennium Development Goal 4 (MDG4) catalysed extraordinary political, financial, and social commitments to reduce under-5 mortality by two-thirds between 1990 and 2015. At the country level, the pace of progress in improving child survival has varied markedly, highlighting a crucial need to further examine potential drivers of accelerated or slowed decreases in child mortality. The Global Burden of Disease 2015 Study (GBD 2015) provides an analytical framework to comprehensively assess these trends for under-5 mortality, age-specific and cause-specific mortality among children under 5 years, and stillbirths by geography over time. METHODS: Drawing from ana…
Determinants of HIV outpatient service utilization according to HIV parameters
2014
Introduction : The increased life expectancy of HIV patients in the era of highly active antiretroviral therapy has had profound consequences for the healthcare systems that provide their care. It is useful to assess whether healthcare resources need to be adapted to the different stages of HIV infection or to patient characteristics [1]. To study how patient features influence utilization of out patient services, we retrospectively analyzed the electronic health record of HIV-positive patients who had followed day-care programs at the AIDS Center of the University of Palermo, Italy. Materials and Methods : 223 HIV-infected subjects were recruited and divided into two groups according to CD…
Congenital Malformations and Syndromes: Early Diagnosis and Prognosis
2012
Congenital malformations are defects of the morphogenesis of organs or body regions identified during intrauterine development or at birth. They may be isolated and single, or multiple. Their global birth prevalence is about 2–3%. Congenital defects may be caused by genetic and/or environmental factors, acting singly or in combination. Diagnostic and therapeutic tools have allowed better identification of congenital malformations and have reduced long-term morbidity and mortality in affected patients. Because of increased life expectancy, congenital malformations today represent a major issue in health care because of the resources needed for multidisciplinary care.
Adjustment mechanisms and intergenerational actuarial neutrality in pension reforms
2016
In the context of the reform of defined benefit pension systems under population ageing, we focus on the introduction of automatic adjustment mechanisms linked to life expectancy. Our goal is to establish a relationship between changes in the key parameters of the pension system and changes in life expectancy, applying the principle of intergenerational actuarial neutrality. For a defined benefit pension scheme, we first obtain the fundamental adjustment equation and then, for particular cases, we derive different designs of automatic adjustment mechanisms depending on the involved parameter. We include a numerical application only for illustrative purposes.
