Evaluation of flu vaccination coverage among healthcare workers during a 3 years’ study period and attitude towards influenza and potential covid-19 vaccination in the context of the pandemic

(1) Background: vaccination of healthcare workers (HCWs) against seasonal influenza is considered the most effective way to protect HCWs, ensure patient’s safety and to maintain essential health care services during influenza epidemics. With the present study we aimed to evaluate the efficacy of incremental bundles of measures implemented during the last three flu campaigns and to assess the attitudes towards influenza vaccination and a potential vaccine against COVID-19 among HCWs, in a large university hospital in Pisa, Italy. (2) Methods: We described measures implemented during 2018/2019, 2019/2020 and 2020/2021 and assessed their impact on flu vaccine coverage (VC) among employees and residents in Pisa university hospital. We considered sex, profession and ward to investigate differences in uptake. In addition, in 2020 a survey was developed and distributed to all employees to evaluate flu and COVID-19 vaccines attitudes. (3) Results: during the 2018/19 and 2019/20 flu campaigns the overall VC rate among HCWs was, respectively, 10.2% and 11.9%. In 2020/21 the overall VC rate jumped to 39.3% (+230.6%). Results from the survey indicated a more positive attitude towards flu vaccine as compared to COVID-19 vaccines among the 10.6% of the staff members who responded to the survey. In addition, 70.97% of HCWs totally agreed that being vaccinated against influenza would be more important than the previous years because of COVID-19 emergency. (4) Conclusions: a significant increase in VC was observed in 2020/21, especially among those sub-groups with consistently lower uptake in previous years. The COVID-19 pandemic positively influenced flu vaccination uptake during the 2020/21 season

The United Nations Security Council and the enforcement of international humanitarian law

This Article discusses the competences and powers of the UN Security Council in securing compliance with international humanitarian law, in particular through the adoption of the measures provided in Chapter VII of the Charter: The competence of the Council in this field can be founded on several legal grounds: on a broad interpretation of the notion of “threat to the peace” (Article 39 of the Charter), on Article 94(2) with regard to the International Court of Justice's judgments establishing violations of the jus in bello and also on the customary duty to ensure respect for international humanitarian law as reflected in Article 1 Common to the 1949 Geneva Conventions on the Protection of the Victims of War. In particular, such customary provision empowers the Security Council to react to any violation of international humanitarian law regardless of a nexus with concerns of international stability. Although the Council has adopted a variety of measures in relation to violations of the laws of war, the most incisive ones are those provided in Articles 41 and 42 of Chapter VII, which however are not without problems. The role the Security Council has played in the enforcement of international humanitarian law has been criticized because of its selective and opportunistic approach, which is due to the political nature of the organ. Also, in several instances the Council, far from securing compliance with the jus in bello, has instead interfered with its application. However selective and imperfect the Council's approach might be, though, its power to adopt decisions binding on UN members and its competence to take or authorize coercive measures involving the use of force make it potentially a formidable instrument against serious violations of international humanitarian law, partly remedying the lack of enforcing mechanisms in the treaties on the laws of war

Forecasting House Prices in Germany

In the academic debate there is a broad consensus that house price fluctuations have a substantial impact on financial stability and real economic activity. Therefore, it is important to have timely information on actual and expected house price developments. The aim of this paper is to measure the latest price movements in different real estate markets in Germany and forecast near-term price developments. Therefore we construct hedonic house price indices based on real estate advertisements on the internet platform ImmobilienScout24. Then, starting with a naive AR(p) model as a benchmark, we investigate whether VAR and ARDL models using additional macroeconomic information can improve the forecasting performance as measured by the mean squared forecast error (MSFE). While these models reduce the forecast error only slightly, forecast combination approaches enhance the predictive power considerably.Die Finanz- und Wirtschaftskrise hat erneut gezeigt, dass Preisfluktuationen am Immobilienmarkt nicht nur einen substanziellen Einfluss auf die Finanzmarktstabilität sondern auch auf die gesamtwirtschaftliche Aktivität ausüben. Demnach ist es aus makroökonomischer Sicht wichtig, Immobilienpreisentwicklungen frühzeitig erkennen und akkurat prognostizieren zu können. Ziel dieser Arbeit ist es, Preisentwicklungen für Deutschland in verschieden Segmenten des Immobilienmarktes am aktuellen Rand zu erfassen und für die kurze Frist von bis zu sechs Monaten zu prognostizieren. Basierend auf monatlich verfügbaren Immobilieninseraten auf der Internetplattform von ImmobilienScout24 werden dazu in einem ersten Schritt hedonische Preisindizes gebildet. In einem zweiten Schritt wird die Entwicklung dieser Preisindizes prognostiziert. Beginnend mit einem einfachen AR(p)-Prozess wird der Informationsgehalt verschiedener zusätzlicher Indikatoren mit Hilfe von VAR und ARDL-Modellen untersucht. Während sich der durchschnittliche quadratische Schätzfehler in den einzelnen Modellen im Vergleich zum AR-Modell nur geringfügig verringert, zeigt sich, dass mit Hilfe von geeigneten Prognosekombinationen die Prognosegüte signifikant verbessert werden kann

An average/deprivation/inequality (ADI) analysis of chronic disease outcomes and risk factors in Argentina

<p>Abstract</p> <p>Background</p> <p>Recognition of the global economic and epidemiological burden of chronic non-communicable diseases has increased in recent years. However, much of the research on this issue remains focused on individual-level risk factors and neglects the underlying social patterning of risk factors and disease outcomes.</p> <p>Methods</p> <p>Secondary analysis of Argentina's 2005 <it>Encuesta Nacional de Factores de Riesgo </it>(National Risk Factor Survey, <it>N </it>= 41,392) using a novel analytical strategy first proposed by the United Nations Development Programme (UNDP), which we here refer to as the Average/Deprivation/Inequality (ADI) framework. The analysis focuses on two risk factors (unhealthy diet and obesity) and one related disease outcome (diabetes), a notable health concern in Latin America. Logistic regression is used to examine the interplay between socioeconomic and demographic factors. The ADI analysis then uses the results from the logistic regression to identify the most deprived, the best-off, and the difference between the two ideal types.</p> <p>Results</p> <p>Overall, 19.9% of the sample reported being in poor/fair health, 35.3% reported not eating any fruits or vegetables in five days of the week preceding the interview, 14.7% had a BMI of 30 or greater, and 8.5% indicated that a health professional had told them that they have diabetes or high blood pressure. However, significant variation is hidden by these summary measures. Educational attainment displayed the strongest explanatory power throughout the models, followed by household income, with both factors highlighting the social patterning of risk factors and disease outcomes. As educational attainment and household income increase, the probability of poor health, unhealthy diet, obesity, and diabetes decrease. The analyses also point toward important provincial effects and reinforce the notion that both compositional factors (i.e., characteristics of individuals) and contextual factors (i.e., characteristics of places) are important in understanding the social patterning of chronic diseases.</p> <p>Conclusion</p> <p>The application of the ADI framework enables identification of the regions or groups worst-off for each outcome measure under study. This can be used to highlight the variation embedded within national averages; as such, it encourages a social perspective on population health indicators that is particularly attuned to issues of inequity. The ADI framework is an important tool in the evaluation of policies aiming to prevent or control chronic non-communicable diseases.</p
