Global public health policies: gathering public health associations' perspectives

Background Advocacy is one of the core functions of public health and is a key tool for achieving Sustainable Development Goals. Public health associations play a key role in advocating for the development and implementation of strategies to prevent diseases and promote health and well-being. Objective This study aims to map out the focus of public health advocacy carried out by selected national public health associations over 4 years, between 2018 and 2021, in order to identify gaps and strengths and support associations and professionals in their advocacy efforts. Methods Twelve national public health associations participated in the study. Official policy documents produced between 2018 and 2021 were collected and analysed. The title and summary of the policy documents were examined line by line and coded into the main subject categories and themes. A qualitative thematic analysis was conducted. Policies were assessed from global and regional perspectives. Results A total of 220 policy documents were analysed. Overall, the largest number of policy documents came from high-income countries and dealt with environmental health and communicable diseases, including COVID-19, with, however, important differences among regions. In the African region, public health advocacy focused mainly on strengthening health systems; Europe and South America were mostly concerned with communicable diseases and pandemic management; and North America and the Western Pacific regions focused primarily on climate change. Limited attention was paid to international health and health as a human right in all regions. Conclusion Our study showed that, especially in high-income countries, public health associations actively engage in advocacy; however, more effort needs to be devoted to implementing a more international and intersectoral approach at the global level, anchored in health as a human right and aligned with the Sustainable Development Goals

Regional scale analysis of the altimetric stream network evolution

International audienceFloods result from the limited carrying capacity of stream channels when compared to the discharge peak value. The transit of flood waves - with the associated erosion and sedimentation processes - often modifies local stream geometry. In some cases this results in a reduction of the stream carrying capacity, and consequently in an enhancement of the flooding risk. A mathematical model for the prediction of potential altimetric stream network evolution due to erosion and sedimentation processes is here formalized. It works at the regional scale, identifying the tendency of river segments to sedimentation, stability, or erosion. The model builds on geomorphologic concepts, and derives its parameters from extensive surveys. As a case study, tendencies of rivers pertaining to the Valle d'Aosta region are analyzed. Some validation is provided both at regional and local scales of analysis. Local validation is performed both through a mathematical model able to simulate the temporal evolution of the stream profile, and through comparison of the prediction with ante and post-event river surveys, where available. Overall results are strongly encouraging. Possible use of the information derived from the model in the context of flood and landslide hazard mitigation is briefly discussed

A global charter for the public\u27s health - The public\u27s health: the role, functions, competencies, education

Political leaders increasingly perceive health as being crucial to achieving growth, development, equity and stability throughout the world. Health is now understood as a product of complex and dynamic relations generated by numerous determinants at different levels of governance. Governments need to take into account the impact of social, environmental and behavioural health determinants, including economic constraints, living conditions, demographic changes and unhealthy lifestyles in many of the World Health Organization (WHO) Member States. This understanding and increasing globalization means it is very timely to review the role of (global) public health in this changing societal and political environment

Efficient Delivery of MicroRNA and AntimiRNA Molecules Using an Argininocalix[4]arene Macrocycle

MicroRNAs (miRNAs) are short non-coding RNA molecules acting as gene regulators by repressing translation or by inducing degradation of the target RNA transcripts. Altered expression of miRNAs may be involved in the pathogenesis of many severe human diseases, opening new avenues in the field of therapeutic strategies, i.e., miRNA targeting or miRNA mimicking. In this context, the efficient and non-toxic delivery of premiRNA and antimiRNA molecules might be of great interest. The aim of the present paper is to determine whether an argininocalix[4]arene is able to efficiently deliver miRNA, premiRNA, and antimiRNA molecules to target cells, preserving their biological activity. This study points out that (1) the toxicity of argininocalix[4]arene 1 is low, and it can be proposed for long-term treatment of target cells, being that this feature is a pre-requisite for the development of therapeutic protocols; (2) the delivery of premiRNA and antimiRNA molecules is efficient, being higher when compared with reference gold standards available; and (3) the biological activity of the premiRNAs and antimiRNAs is maintained. This was demonstrated using the argininocalix[4]arene 1 in miRNA therapeutic approaches performed on three well-described experimental model systems: (1) the induction of apoptosis by antimiR-221 in glioma U251 cells; (2) the induction of apoptosis by premiR-124 in U251 cells; and (3) the inhibition of pro-inflammatory IL-8 and IL-6 genes in cystic fibrosis IB3-1 cells. Our results demonstrate that the argininocalix[4]arene 1 should be considered a very useful delivery system for efficient transfer to target cells of both premiRNA and antimiRNA molecules, preserving their biological activity

Thoracic Endovascular Aortic Repair for Type B Acute Aortic Dissection Complicated by Descending Thoracic Aneurysm

OBJECTIVES: To analyse the results and review the literature about thoracic aortic endovascular repair (TEVAR) for type B acute aortic dissection (TBAAD) complicated by descending thoracic aortic aneurysm (DTA) in the hyperacute or acute phases. METHODS: This was a multicentre, observational descriptive study. Inclusion criteria were TBAAD with a DTA of 6550 mm, TBAAD on an already known aneurysmal descending thoracic aorta, and TBAAD presenting with an enlarged aorta with a total diameter <50 mm, but with >50% diameter increase compared with a previous computed tomography angiography (CTA) showing a non-dissected aorta with normal sizing. Primary endpoints were early and long-term survival, freedom from TEVAR and aortic related mortality (ARM), and freedom from re-intervention. RESULTS: Twenty-two patients were included in the analysis. The mean aortic diameter was 66 \ub1 26 mm (range 42-130; IQR 51-64). The in hospital TEVAR related mortality was 14% (n = 3). The mean radiological follow-up was 56 \ub1 45 months (range 6-149; IQR 12-82), and the follow-up index 0.97 \ub1 0.1. All surviving patients were available for follow-up. During follow-up the cumulative mortality was 26% (n = 5) and TEVAR related mortality was 5% (n = 1). Overall the estimate of survival was 82% (95%CI: 61.5-93) at 1 year, and 64% at 5 years. Ongoing primary clinical success was 79% (re-intervention n = 4). Freedom from aortic related mortality was 86% (95%CI: 66-95) at 1 and 5 year, while freedom from re-intervention was 95% (95%CI: 75.5-95) at 1 year, and 77% (95%CI: 50-92) at 5 years. CONCLUSIONS: In our experience, DTA is a frequent complication from the very beginning of the clinical onset of TBAAD. In this high-risk cohort, TEVAR showed satisfactory results, better than those predicted by the risk score for open repair, with favourable stability of the aortic diameter and no aortic related adverse events during follow-up

Media response to colon cancer campaigns in Switzerland 2005-2007: regional newspapers are the most reliable among the printed media

<p>Abstract</p> <p>Background</p> <p>Health campaigns are frequently covered by printed media, but coverage is not homogeneous across different types of newspapers. Switzerland as a multilinguistic country with many newspapers offers a good field for study. A better understanding of how printed media report on national campaigns against colon cancer in the three main linguistic regions may help to improve future public health interventions. Therefore, we analyzed articles published between 2005 and 2007 during the campaigns "<it>Darmkrebs-nie</it>?" and "<it>Self-Care</it>" in the German, French and Italian regions of Switzerland.</p> <p>Findings</p> <p>Some 65% of articles reporting on colon cancer were in German, 23% and 12% were in French and Italian respectively. During the campaign, topics linked to colon cancer were increasingly covered by the media. Regional newspapers (66%) reported significantly more about colon cancer and produced the most detailed articles.</p> <p>Both gain- and loss-framed messages have been used by journalists, whereas the campaigns used merely gain-framed messages. Latin (French and Italian) newspapers mixed gain- and loss-framed messages in the same articles, while German articles mainly used a single frame throughout.</p> <p>Conclusions</p> <p>Swiss-German papers reported more about the topic and the reporting was quantitatively and qualitatively more prominent in regional papers. The press followed the campaigns closely only during the period of campaigning, with high coverage. We propose to consider the regional press as an important vehicle of health information. Moreover, slight differences in framing can be observed between German and Latin articles.</p

Ectopic Expression of E2F1 Stimulates β-Cell Proliferation and Function

OBJECTIVE-Generating functional beta-cells by inducing their proliferation may provide new perspectives for cell therapy in diabetes. Transcription factor E2F1 controls G(1)- to S-phase transition during the cycling of many cell types and is required for pancreatic beta-cell growth and function. However, the consequences of overexpression of E2F1 in beta-cells are unknown. RESEARCH DESIGN AND METHODS-The effects of E2F1 overexpression on beta-cell proliferation and function were analyzed in isolated rat beta-cells and in transgenic mice. RESULTS-Adenovirus AdE2F1-mediated overexpression of E2F1 increased the proliferation of isolated primary rat beta-cells 20-fold but also enhanced beta-cell death. Coinfection with adenovirus Ad Akt expressing a constitutively active form of Akt (protein kinase B) suppressed beta-cell death to control levels. At 48 h after infection, the total beta-cell number and insulin content were, respectively, 46 and 79% higher in AdE2F1+AdAkt-infected cultures compared with untreated. Conditional overexpression of E2F1 in mice resulted in a twofold increase of beta-cell proliferation and a 70% increase of pancreatic insulin content, but did not increase beta-cell mass. Glucose-challenged insulin release was increased, and the mice showed protection against toxin-induced diabetes. CONCLUSIONS-Overexpression of E2F1, either in vitro or in vivo, can stimulate beta-cell proliferation activity. In vivo E2F1 expression significantly increases the insulin content and function of adult beta-cells, making it a strategic target for therapeutic manipulation of beta-cell function.

Custom Made Candy Plug for Distal False Lumen Occlusion in Aortic Dissection: International Experience

Objective: To evaluate early and midterm outcomes of the Candy Plug (CP) technique for distal false lumen (FL) occlusion in thoracic endovascular aortic repair for aortic dissection (AD) in a more real world cohort of patients from an international multicentre registry. Methods: A multicentre retrospective study was conducted of all consecutive patients from the contributing centres with subacute and chronic AD treated with the CP technique from October 2013 to April 2020 at 18 centres. Results: A custom made CP was used in 155 patients (92 males, mean age 62 ± 11 years). Fourteen (9%) presented with ruptured false lumen aneurysms. Technical success was achieved in all patients (100%). Clinical success was achieved in 138 patients (89%). The median hospital stay was 7 days (1 – 77). The 30 day mortality rate was 3% (n = 5). Stroke occurred in four patients (3%). Spinal cord ischaemia occurred in three patients (2%). The 30 day computed tomography angiogram (CTA) confirmed successful CP placement at the intended level in all patients. Early complete FL occlusion was achieved in 120 patients (77%). Early (30 day) CP related re-intervention was required in four patients (3%). The early (30 day) stent graft related re-intervention rate was 8% (n = 12). Follow up CTA was available in 142 patients (92%), with a median follow up of 23 months (6 – 87). Aneurysmal regression was achieved in 68 of 142 patients (47%); the aneurysm diameter remained stable in 69 of 142 patients (49%) and increased in five of 142 patients (4%). A higher rate of early FL occlusion was detected in the largest volume centre patients (50 [88%] vs. 70 [71%] from other centres; p = .019). No other differences in outcome were identified regarding volume of cases or learning curve. Conclusion: This international CP technique experience confirmed its feasibility and low mortality and morbidity rates. Aortic remodelling and false lumen thrombosis rates were high and support the concept of distal FL occlusion in AD using the CP technique
