Development assistance for health (DAH) remains a significant and important source of health financing in many low and lower middle-income countries. However, this assistance has not been fully effective. This study explores the effect of currency exchange rate fluctuations on volatility of DAH in Zambia using a mixed methods approach. Data covering the period 1997-2008 were collected from various
The slow global response to the Ebola crisis in west Africa suggests that important gaps exist in donor financing for key global functions, such as support for health research and development for diseases of poverty and strengthening of outbreak preparedness. In this Health Policy, we use the International Development Statistics databases to quantify donor support for such functions. We classify d
Zambia introduced a sector-wide approach (SWAp) in the health sector in 1993. The goal was to improve efficiency in the use of domestic funds and externally sourced development assistance by integrating these into a joint sectoral framework. Over a decade into its existence, however, the SWAp remains largely unevaluated. This study explores whether the envisaged improvements have been achieved by
The study aims to determine if genetic polymorphisms in the human leukocyte antigen (HLA)-G gene are associated with age-related macular degeneration (AMD). HLA-G is important for immunological tolerance, and it is also known to have angiogenic effects. Polymorphisms in the 5'-upstream regulatory region (URR) and 3'-untranslated region (UTR) of HLA-G have been associated with a number of diseases,
We have reviewed studies investigating the effect of physical activity on prevention of early age-related macular degeneration (AMD), progression to late AMD, and risk modulation of morbidity and mortality in patients with AMD. Regular physical activity may lower risk of developing early AMD and progression of early AMD to late AMD at a level comparable with smoking cessation or dietary supplement
Globalising dynamics have had wide-ranging and pervasive impacts on nearly every form of human relatedness, which now include the bases upon which states calculate and express their political responsibilities. As the ‘reach’ of practical and normative pressures extends and their demands intensify, the compass of state responsibility is becoming a key pressure point for facing the challenges and me
Polypoidal choroidal vasculopathy (PCV) and neovascular age-related macular degeneration (AMD) are prevalent age-related diseases characterized by exudative changes in the macula. Although they share anatomical and clinical similarities, they are also distinctly characterized by their own features, e.g. vascular abnormalities in PCV and drusen-mediated progression in neovascular AMD. PCV remains e
Age-related macular degeneration (AMD) is a degenerative disease of the retina and a leading cause of irreversible vision loss. We investigated the systemic differences in the frequency of T helper (Th) 1 and Th17 cells in patients with non-exudative and exudative AMD and compared to age-matched controls. Flow cytometry was used to determine the systemic frequency of Th1 (CD4+CXCR3+IL12RB2+) and T
Age-related macular degeneration (AMD) has been associated with both systemic and ocular alterations of the immune system. In particular dysfunction of complement factor H (CFH), a soluble regulator of the alternative pathway of the complement system, has been implicated in AMD pathogenesis. One of the ligands for CFH is long pentraxin 3 (PTX3), which is produced locally in the retinal pigment epi
It is considered unavoidable that there is some variation in how different fire services assess matters in the building process. However, it is unclear how great this variation is. A large variation can be problematic because it can result in that different municipalities make different demands on similar projects. The purpose of this work is to investigate how large this variation can be with a R
PURPOSE: The chemokine receptors CX3CR1 and CCR2 have been implicated in the development of age-related macular degeneration (AMD). The evidence is mainly derived from experimental cell studies and murine models of AMD. The purpose of this study was to investigate the association between expression of CX3CR1 and CCR2 on different leukocyte subsets and AMD. Furthermore we measured the plasma levels
PURPOSE: We have recently identified homeostatic alterations in the circulating T cells of patients with age-related macular degeneration (AMD). In cultures of retinal pigment epithelial cells, we have demonstrated that T-cell-derived cytokines induced the upregulation of complement, chemokines and other proteins implicated in AMD pathogenesis. The purpose of this study was to test whether increas
PURPOSE: The chemokine receptor CXCR3 has been strongly related to inhibition of angiogenesis. The purpose of this study was to investigate the association between expression of CXCR3 on peripheral blood leukocytes and age-related wet macular degeneration. Furthermore, we measured the plasma concentration of chemokines CXCL9 to -11.METHODS: The study group consisted of patients with age-related ma
Age-related macular degeneration (AMD) is a leading cause of visual impairment in the aged population worldwide. The mechanisms underlying this multifactorial and heterogenic disease are complex and incompletely understood. There is increasing evidence to suggest that regulatory differences in the immune system are involved in the development of the various subtypes of AMD. The purpose of this the
OBJECTIVES: To evaluate potential differences in plasma 25-hydroxyvitamin in subtypes of age-related macular degeneration (AMD), and in patients in Clinical Age-Related Maculopathy Staging (CARMS) group 5 with or without subretinal fibrosis.METHODS: This single-center cross-sectional study included 178 participants during a period of 20 months. Ninety-five patients belonged to CARMS 5; twelve belo
BACKGROUND: Dysregulation of the CCR3/CCL11 pathway has been implicated in the pathogenesis of choroidal neovascularisation, a common feature of late age-related macular degeneration (AMD). The aim of this study was to investigate the expression of CCR3 and its ligand CCL11 in peripheral blood in patients with neovascular AMD.METHODS: Patients with neovascular AMD and healthy controls were include
PURPOSE: To investigate the expression of the complement regulatory proteins CD46, CD55, and CD59 on peripheral leukocytes in neovascular age-related macular degeneration (AMD).DESIGN: Prospective, case-control study.METHODS: Thirty-five unrelated patients with neovascular AMD and 30 control individuals were included in this case-control study. All participants were subjected to a structured inter
PURPOSE: Association of neovascular age-related macular degeneration (AMD) with C-reactive protein (CRP) was previously reported, indicating a relation to systemic low-grade inflammation. However, visual impairment limits physical activity, and physical activity modulates CRP levels. Here, we investigated the impact of physical activity on CRP levels in patients with neovascular AMD and control in
