Published: July 2024

The WegenerNet climate station network Feldbach Region has provided measurements of hydrometeorological near-surface and surface variables with very high spatial and temporal resolution since 2007. It was specifically built as a long-term weather and climate monitoring facility that provides an open-ended data record to help fill the gap between short-term, high-resolution observations and long-term observations at larger scales. In 2020, this ground station network was complemented by the WegenerNet 3D Open-Air Laboratory for Climate Change Research, which has added atmospheric sounding capabilities through a polarimetric X-band Doppler weather radar, a microwave radiometer for vertical profiling of temperature, humidity, and cloud liquid water, an infrared cloud structure radiometer, and a water-vapor-mapping GNSS station network. Together, these facilities provide a unique setup for studying extreme meteorological events in a changing climate. To maximize the impact of these data an open data store and open science tools, based on widely adopted and recognized (metadata) standards, are in the process of being implemented as part of the project WEGN2OPEN. Its focus lies on the provision of innovative high-resolution data cubes with a high level of interoperability to allow for an easy integration into existing applications and workflows.The aim of this contribution is to showcase the current state of the WEGN2OPEN data store, along with planned advancements and features. This includes an overview of the currently available APIs through which datasets can be discovered and accessed, the web application for browsing, viewing, and subsetting data, and an outlook to a future extension with cloud-based analysis and processing tools.

Published: July 2024

Extreme heat endangers human health and well-being and impairs the use of public spaces. Dortmund’s Integrated Climate Adaption Master Plan prioritizes actions and measures to improve heat resilience. This project supports the city of Dortmund (Germany) in attaining this goal, by deploying a state-of-the-art biometeorological sensor network and developing a nowcasting service for monitoring thermal comfort across the city. The project aims to pioneer the integration of thermal comfort data in smart-city ecosystems and provide actionable insights for the development of Dortmund’s Heat Action Plan. In-situ, remotely sensed and Modeled data will be used to provide near-real-time information of outdoor thermal conditions including thermal comfort indices. City-Officials of Dortmund are involved in the design of the dashboard and the weather station network, ensuring they meet their needs and will be used in practice. The collected data will be used in a series of on-ground actions, supporting the evaluation of existing climate adaption measures, and the design of new ones. These actions include the mapping of areas with high potential for planting trees, the investigation of changes in human behavior during hot days, and the assessment of backyard greening strategies. To engage with the local stakeholders, promote the role of citizen scientists, and disseminate the project, a series of workshops and on-site events are planned, such as climate comfort labs, mobile measurement campaigns, or climate walks with citizens. The overall goal of the project is for the city of Dortmund to adopt and integrate the developed network and nowcasting service into its smart-city ecosystem.
Exceptional atmospheric conditions in June 2023 generated Northwest European marine heatwave which contributed to breaking land temperatures records

Published: July 2024

The Northwest European shelf experienced unprecedented surface temperature anomalies in June 2023 (anomalies up to 5 °C locally, north of Ireland). The shelf average underwent its longest recorded category II marine heatwave (2.9°C anomaly for 16 days). With state-of-the-art observation and modelling capabilities, we completed an in-depth analysis of its origins, its feebacks on the weather and its likelihood of future recurrence. We showed the marine heatwave developed quickly due to strong atmospheric forcing (record high level of sunshine, weak winds, tropical air) and record weak wave activity under two weeks of anticyclonic weather regimes. Additionally, tidal activity (neap/spring tide) modulated the marine heatwave and contributed to its spatial heterogeneity. Once formed, this shallow marine heatwave fed back on the weather: over the sea it reduced cloud cover, helping to sustain the marine heatwave itself. Over land, it contributed to breaking June mean temperature records and to enhanced convective rainfall through stronger, warmer and moister sea breezes. This marine heatwave was intensified by the last 20-year warming trend in sea surface temperatures. Such sea surface temperatures are projected to become commonplace by the middle of the century under a high greenhouse gas emission scenario. This study was enabled by strong collaborations between observers and modellers of the ocean, waves and atmosphere. It highlights the necessity of long-term ocean observation for monitoring regional seas, complemented by regional reanalyses and climate projections. It also illustrates the usefulness of regional coupled systems for process understanding, short term weather forecasting and their potential for adding value to regional climate information.
Spatially compounding extremes under omega blocking

Published: July 2024

In the beginning of September 2023, Europe experienced a pronounced atmospheric omega-blocking, marked by a persistent anticyclone in the center flanked by two low pressure systems to the southwest and southeast. By definition, an atmospheric block interrupts the mean westerly flow and leads to prolonged persistent conditions lasting for at least five days. The core of the omega-blocking in September 2023 was located over Central Europe and Southern Scandinavia, which experienced a heatwave in the first week of September 2023. On the other hand, areas situated on the southwestern (Spain) and southeastern flanks (Greece, Bulgaria, and later Libya) were hit by extreme precipitation leading to major flood events.We employ the method of ensemble boosting to explicitly simulate omega blocking situations with spatially compounding extremes (heatwave and extreme precipitation) with the Community Earth System Model 2 (CESM2). Using this model re-initialization approach, slight perturbations are introduced to initial conditions 10 to 25 days prior to the event, leading to the generation of hundreds of coherent physical event trajectories. This allows to study two sets of research questions: the first focuses on assessing the capability of the climate model to reproduce the 2023 event in its severity, while the second deals with identifying the primary factors of the omega block that result in the most severe impacts on the ground.In our presentation, we introduce the research concept and address the following research questions: Is the CESM2 model capable of reproducing an omega blocking event with spatially compounding extremes in the magnitude of the September 2023 event? Could the September 2023 event have been even more devastating by chance? What characteristics of the omega block precondition the occurrence of the most extreme impacts in terms of heatwaves and extreme precipitation within the boosted ensemble?
Testing evapotranspiration retrieval approaches over Hungarian agricultural fields
Authors: Gelybó Györgyi , Shaifei Mahrokh
Published: July 2024

Evapotranspiration (ET) is a key element of water cycle especially over vegetated surface. Vegetation in Hungary is often prone to drought events, while exact information on water need of different species is barely available.  Vast majority of the agricultural lands are rainfed, without the option of irrigation, hence water balance components are in the focus of research interest in case of different agricultural settings. Moreover, crop growth models of different approaches rely heavily on ET estimations. Water balance components are essential to assess crop health, or estimate future crop growth.In this work we present calculations of actual evapotranspiration using different methods. Flexibility in parameterization, data requirements and their availability and performance are tested in case of all methods to select the best candidates for Hungarian agricultural applications. We use empirical and process based approaches to evaluate the feasibility of the methods in case of Hungarian conditions. A multiannual analysis ensures that the differences among years are better considered. To ensure that data on other components of water balance are considered, we apply the ET estimation methods to selected stations of the drought monitoring network of General Directorate of Water Management, where continuous soil moisture content data are recorded. Measurement stations are located typically over agricultural fields. Representation of different crop and soil types are ensured in site selection. Weather data for the ET calculations are provided by the homogenized and gridded database of the HungaroMet (Hungarian Meteorological Service). In the future eddy covariance based and lysimeter data will serve as basis for the validation of potential models.
An Unbiased High-Resolution Climate Dataset for Solar Energy Applications

Published: July 2024

Assessing renewable energy resources under future climate scenarios has been highlighted in recent years to analyze and understand potential impacts of future change in renewable generation on the power sector. Solar energy is well-known as the most plentiful among various renewable resources and usually converted to electricity using photovoltaics (PV) technologies, and the global deployment of PV technology has increased rapidly in recent decades. In this study, we develop a statistical technique to downscale the future projection of solar irradiance for PV energy-related applications. A set of Regional Climate Model (RCM)-based projections obtained from the North American Coordinated Regional Climate Downscaling Experiment (NA-CORDEX) are used as inputs to statistical methods to generate high-resolution global horizontal irradiance (GHI) over the contiguous United States (CONUS). The main steps of the statistical downscaling method include (1) regridding RCM output (0.22 degree and daily resolutions) to handle the modeled-observed data sets on a common grid, (2) correcting bias of RCM GHI using satellite-derived observation, and (3) implementing temporal and spatial downscaling to generate GHI at 8-km and hourly resolution. Basically, complex physical processes and interactions between solar radiation and various atmospheric constituents lead solar irradiance to be highly variable and uncertain. Underrepresentation of clouds from the RCM parameterizations is the main source of error and uncertainty in modeling solar irradiance. Thus, we adapt and use the high-quality satellite-derived data from the National Solar Radiation Database (NSRDB) to analyze the bias and error of RCM GHI as well as estimate the statistical parameters for spatial and temporal downscaling. This presentation will summarize the comprehensive analysis conducted to produce and assess the results under two climate scenarios (RCP4.5 and RCP8.5). We will also present a detailed validation demonstrating the strengths of the proposed downscaling method and future extension of this research.
Size resolved aerosol fluxes above a deciduous forest: seasonal variability and underlying processes
Authors: Bignotti Laura , Gerosa Giacomo Alessandro , Finco Angelo , Marzuoli Riccardo
Published: July 2024

Atmospheric aerosol is a global concern for its detrimental effects on human health and climate. Vegetation has been identified as a possible sink for atmospheric particles. However, the interactions between vegetation and aerosols are not completely understood, and they are not limited to deposition only since also bidirectional aerosol exchanges can appear. Moreover, the knowledge of aerosol-vegetation interactions is quite limited for deciduous forests, as well as its seasonality which follows the appearance and disappearance of leaves on the crowns. Much of research, in fact, has been focused on conifers which have almost constant leaf area during the year.For this sake, eddy covariance measurements of size-resolved aerosol fluxes were conducted in a broadleaf deciduous forest in the Po Valley, by means of a fast electric low-pressure impactor able to resolve 14 dimensional classes with cut-off diameters ranging from 6 nm to 10 µm. The measurements spanned approximately eight months and covered both a leaf-off period and a leaf on period, from leaf sprout to leaf senescence.Overall, aerosol fluxes exhibited a distinct seasonality and variations in exchange direction depending on particle diameter. During the winter, when leaves were absent, most aerosol classes exhibited positive upward fluxes. In contrast, during the leaf-on season, ultrafine (dp
Surface-layer scaling of velocity, temperature and transport processes in thermally-driven slope winds
Authors: Farina Sofia , Zardi Dino
Published: July 2024

The atmospheric boundary layer (ABL) in mountainous regions is characterised by a variety of airflows, shaped by different landforms, which encompass a range of scales of motion, from synoptic scale flows to very local phenomena. Among them, a particular role is played by the daily-periodic thermally-driven circulation systems developing over the inclines and in the valleys under clear skies and in the absence of major synoptic forcing. These airflows, and turbulence generated therein, affect a variety of processes, including surface-atmosphere exchanges of momentum, energy and mass, and transport across a variety of scales. They may also contribute to the initiation of orographic convection.  The simplest of these wind systems are those which develop over simple slopes, i. e. the so-called slope winds. The structure of turbulence properties and their representation in terms of similarity scaling are still quite debated in the literature. Based on theoretical arguments and on the analysis of data from a variety of field experiments, it is shown that the Obukhov length is still the appropriate lengthscale for the structure of velocity and temperature profiles as well as for the eddy viscosity and eddy diffusivity. However the slope-normal structures of first- and second-order turbulence moments are quite different from those valid for flat horizontal terrains. Also momentum flux and heat flux at the surface are not two independent proerties, bur rather interconnected. Ongoing efforts to pursue further the investigation on these flows within the current initiative TEAMx - Multi-scale transport and exchange processesin the atmosphere over mountains – programme and experiment (http://www.teamx-programme.org/)  are also presented.

The European drought of 1921 is assessed in terms of its impacts on society and in terms of its physical characteristics. The development of impacts of the drought are categorized by a systematic survey of newspaper reports from five European newspapers covering the area from England to the Czech Republic and other parts of Europe. This is coupled to a reconstruction of daily temperature and precipitation based on meteorological measurements to quantify the drought severity and extent, and reanalysis data are used to identify its drivers. This analysis shows that the first impacts of the drought started to appear in early spring and lingered on until well into autumn and winter, affecting water supply and agriculture and livestock farming. The dominant impact in western Europe is on agriculture and livestock farming while in central Europe the effects of wildfires were reported on most often. The peak in the number of reports is in late summer. Preceding the first impacts was the dry autumn of 1920 and winter 1920–1921. The area hardest hit by the drought in the following spring and summer was the triangle between Brussels, Paris and Lyon, but a vast stretch of the continent, from Ireland to the Ukraine, was affected. The reported impacts on water supply and water-borne transport in that region were matched by an analysis of the hydrological situation over the Seine catchment. On average, the 1921 summer was not particularly hot, but the heatwave which was observed at the end of July saw temperatures matching those of the heatwaves in modern summers. Similar to modern droughts, an anticyclone was present roughly over the British Isles, maintaining sunny and dry weather in Europe and steering away cyclones to the north. Its persistence makes it exceptional in comparison to modern droughts.The 1921 drought stands out as the most severe and most widespread drought in Europe since the start of the 20th century. The precipitation deficit in all seasons was large, but in none of the seasons in 1920 and 1921 was the precipitation deficit the largest on record. The severity of the 1921 drought relates to the conservative nature of drought which amplifies the lack of precipitation in autumn and winter into the following spring and summer.
A New Year-Round Weather Regime Classification for North America
Authors: Lee Simon , Tippett Michael , Polvani Lorenzo , Malloy Kelsey
Published: July 2024

Large-scale, recurrent and persistent regional atmospheric circulation patterns – known as weather regimes – are increasingly used in subseasonal-to-seasonal prediction and in analysis of climate variability and change. Yet, the majority of existing studies have focused on regimes in the North Atlantic-European sector, with comparably fewer studies investigating North American regimes. An additional limitation stems from the seasonal dependence of existing North American regime classifications, which primarily focus on winter. Here, we normalize the seasonal cycle in daily geopotential height variance over North America and use empirical orthogonal function analysis combined with k-means clustering to define a new set of four year-round North American weather regimes: the Pacific Trough, Pacific Ridge, Alaskan Ridge, and Greenland High regimes. Additionally, we define a fifth ‘No Regime’ state to represent conditions closer to climatology than any of the regimes. Multiple statistical tests support the choice of four regimes, and the clustering solution is robust to various methodological choices. All four regimes typically persist for around one week, with instances of extremely long-lived regimes persisting for up to six weeks, while the No Regime state is mostly associated with regime transitions and typically persists for only a few days. Regime-associated temperature and precipitation anomalies are reported, alongside the link between regimes and the modulation of tornado activity across the United States. We also use the regimes to objectively quantify historical trends in the large-scale circulation over North America during 1979—2023, finding a large increase in the frequency and persistence of the Greenland High regime during summer, particularly since 2007.
Characteristics of large-scale circulation "forecast busts” over Europe in ERA5 medium-range reforecasts
Authors: Hauser Seraphine , Martin Jonathan E. , Cavallo Steven , Parsons David B.
Published: July 2024

Despite rapid improvement in global-scale numerical weather prediction systems, forecast centers repeatedly experience notable declines in their systems’ forecast accuracy. These occasional very poor forecasts are often referred to as “forecast busts” and lead to perceptible differences in the anticipated weather. It is therefore important to understand the causes and the origins of "forecast busts” through a systematic analysis. Previous studies made use of reforecasts (or often referred to as hindcasts) to investigate hundreds of “forecast busts” from a fixed forecast model. The mean characteristics but also the different flavors of “forecast busts” have been investigated based on ERA-Interim reforecasts from the European Centre for Medium-Range Weather Forecasts (ECMWF). However, a deeper analysis of these events, particularly by using reforecast of ECMWF's most recent reanalysis (ERA5), is still missing.  

In this study, we identify “forecast busts" over Europe based on the day 6 anomaly correlation coefficient forecast skill of geopotential height at 500 hPa using ERA5 reforecasts of the period 1979-2023. Characteristics of these events are compared to the characteristics of “forecast busts” in an earlier model version (ERA-Interim), but also – for the first time – compared to exceptionally good forecasts in order to gain a better understanding of the strengths and weaknesses of the CY41R2 of the ECMWF Integrated Forecast System in predicting the large-scale pattern over Europe. To further extend the range of analyses on “forecast busts”, we systematically investigate various flavors of error patterns over Europe on forecast day 6 and discuss their distinct error pattern evolution and weather impacts over Europe.  

 
A Simulation Study Air Pollution Impact from Roman Potteries in Augusta Treverorum (Trier)
Authors: Drüe Clemens
Published: July 2024

This study models the dispersion of historic air pollution from pottery kilns in the Roman city Augusta Treverorum (Trier). It aims to improve the understanding of their impact on urban air quality during different historical phases. Utilizing archaeological data on pottery locations and historical urban growth patterns, we simulated air pollution levels across the city, focusing on periods before and after the relocation of pottery kilns from various sites spread out over the settlement area to a confined pottery district near the Mosel River. This district is locate in the southwest corner of the city, which is striking as this position is upwind to the city center for the most frequent wind directions along the valley axis. All modern smoke-emitting industry accordingly is found in the opposite northeastern part of the city.For the simulation we used the German regulatory pollution dispersion model AUSTAL, driven by weather data from the European reanalysis. The sources were modeled after measurements taken during experimental pottery production by LEIZA, Mains in a reconstructed kiln. We found that pollution from the sites spread out over the city predominantly affected the city's northern half, where significant buildings such as the Emperor's Palace and temples were located. The production sites in the pottery district, in contrast, have been impacting the southern part of the city, that must have been a predominantly residential area. This impact is rather independent from the location of a kiln inside the pottery district. The results suggests that this pattern is not a random outcome, but a result urban planning decisions in Augusta Treverorum that were influenced by air pollution, demonstrating a historic example of industrial activity's environmental implications. 
Skin sea surface temperature schemes in coupled ocean–atmosphere modelling: the impact of chlorophyll-interactive e-folding depth

Published: July 2024

Abstract. In this paper, we explore different prognostic methods to account for skin sea surface temperature diurnal variations in a coupled ocean–atmosphere regional model of the Mediterranean Sea. Our aim is to characterise the sensitivity of the considered methods with respect to the underlying assumption of how the solar radiation shapes the warm layer of the ocean. All existing prognostic methods truncate solar transmission coefficient at a warm-layer reference depth that is constant in space and time; instead, we implement a new scheme where this latter is estimated from a chlorophyll dataset as the e-folding depth of solar transmission, which thus allows it to vary in space and time depending on seawater's transparency conditions. Comparison against satellite data shows that our new scheme, compared to the one already implemented within the ocean model, improves the spatially averaged diurnal signal, especially during winter, and the seasonally averaged one in spring and autumn, while showing a monthly basin-wide averaged bias smaller than 0.1 K year-round. In April, when most of the drifters' measurements are available, the new scheme mitigates the bias during nighttime, keeping it positive but smaller than 0.12 K during the rest of the monthly averaged day. The new scheme implemented within the ocean model improves the old one by about 0.1 K, particularly during June. All the methods considered here showed differences with respect to objectively analysed profiles confined between 0.5 K during winter and 1 K in summer for both the eastern and the western Mediterranean regions, especially over the uppermost 60 m. The new scheme reduces the RMSE on the top 15 m in the central Mediterranean for summertime months compared to the scheme already implemented within the ocean model. Overall, the surface net total heat flux shows that the use of a skin sea surface temperature (SST) parameterisation brings the budget about 1.5 W m−2 closer to zero on an annual basis, despite all simulations showing an annual net heat loss from the ocean to the atmosphere. Our “chlorophyll-interactive” method proved to be an effective enhancement of existing methods, its strength relying on an improved physical consistency with the solar extinction implemented in the ocean component.
Policy Trade-Offs in Decisions on the Provision of Emergency Homeless Shelter Beds in Canada
Authors: Kneebone Ronald , Wilkins Margarita
Published: July 2024

Why do some cities provide many emergency shelter beds while others do not? We interpret differences with respect to the supply of shelter beds as originating from alternative choices concerning a series of policy trade-offs. These trade-offs arise because of climate effects, prejudice, levels of poverty, and housing and labour market conditions affecting the rates of homelessness. Governments have policy levers they can adjust to respond to changes in most, if not all these conditions. One of these policy levers is the number of emergency shelter beds that are made available. But other policy responses are also possible. These include efforts to reduce poverty, policies designed to increase the stock of affordable housing, and policies to increase income support payments. Choosing to supply shelter beds over other policy responses reveals a preference for one set of societal outcomes over another. Using data describing conditions in 52 Canadian cities, we test six hypotheses describing why some communities choose to provide more homeless shelter beds than others.
Las dificultades de la investigación en historia social del cine: Alba de América (Orduña, 1951)

Published: July 2024

Este artículo tiene como objetivo analizar los problemas a los que se enfrenta una investigación en Historia social del cine a través del estudio de la película Alba de América (Orduña, 1951). El filme, que narra el descubrimiento de América, se considera una de las principales obras de propaganda histórica del régimen. La literatura académica afirma que fue producida como respuesta a la película inglesa Chistopher Columbus (McDonald, 1949) y que en su realización intervinieron importantes figuras como Carrero Blanco. Con el fin de corroborar estas afirmaciones y descubrir las lagunas que existen en torno a la obra, se ha procedido a la consulta de documentación relativa a su producción. Esto ha permitido detectar algunos de los desafíos que todo investigador de esta materia debe afrontar: la asunción de planteamientos considerados históricamente ciertos, pero no confirmados, la divergencia de interés en los descriptores temáticos de los archivos o la dificultad de acceder a determinados fondos. Aunque la investigación está incompleta, ya que no se ha podido acceder a parte de la documentación, la información encontrada ha corroborado la necesidad de un mejor y mayor acceso a los archivos, así como de una mirada más ecuánime sobre la cinematografía franquista.
Ethanolic Distillation: A case study of ethanol loss upon degassing.
Authors: Camillo Del Vecchio Giovanna , Carla Guimarães Camila , Neves Câmara Claudionor , Madaleno Leonardo Lucas
Published: July 2024

Ethanol plays a crucial role in Brazilian and global contexts, serving as a viable and sustainable alternative to fossil fuels. Brazil stands out as a leader in ethanol production, particularly from sugarcane, thereby establishing itself as a benchmark in industrial sustainability. The country's large-scale production of this biofuel boosts the national economy and promotes diversification of the energy matrix, reducing reliance on nonrenewable fuels. The efficiency of ethanol production is inherently linked to minimizing losses during the process. Therefore, the primary objective of this article was to describe the factors that affect ethanol loss during the degassing process. For this purpose, a case study was conducted involving interviews with operators from the alcohol distillation sector of two sugarcane energy plants and extensive research based on the literature. The findings of this study indicate that parameters such as temperature, pressure, and composition of the wort directly influence ethanol loss during degassing. Furthermore, the alignment between manual and automated activities is an essential factor in overcoming these challenges faced by the sector, ensuring reduced losses in this process and maintaining the quality of the produced ethanol.

Objective: to investigate pro- and anti-inflammatory markers and blood adipokines in young people with arterial hypertension (AH) on the background of abdominal obesity (AO).

   Materials and methods. 510 people were included in the study, of which 257 people with hypertension, of which 164 were with AO. In the control group (without AH) there were 253 people of comparable gender and age, with AO – 101 people. The content of adipsin, lipocalin-2, resistin, TNF-α, IL-6, IL-8, IL-10, IL-17a, IL-17e, IL-17f was determined in all blood by multiplex analysis. Statistical processing was carried out in the SPSS 13.0 program.

   Results. When comparing the studied parameters in the studied groups, statistically significant differences were obtained for lipocalin-2, resistin, adipsin, IL-6 and IL-17a, all these indicators were higher in the group with hypertension. There was no difference between the control and the group with hypertension in other biomarkers. There was no effect of AO on the level of the studied markers in the control group. For the main group, the difference between the subgroups with and without AO was obtained for lipocalin. Also, the systolic pressure level was significantly higher in the group with AO. Correlation analysis revealed a weak association of systolic and diastolic blood pressure with TNF-α, IL-6, adipsin, lipocalin-2, resistin and waist circumference. the association of body mass index with lipocalin-2, IL-6 and TNF-α (p < 0.01), a strong association of adipsin, lipocalin-2, resistin with TNF-α and IL-17a (p < 0.01).

   Conclusion. Of the markers we studied, elevated levels of adipsin, lipocalin-2, resistin, IL-6 and IL-17a can serve as potential biomarkers indicating a high probability of developing early hypertension in people under 45 years of age. Systolic and diastolic blood pressure levels also increase with an increase in waist circumference.

Published: July 2024

Aim. To evaluate the associations of VEGFR2 rs2305948 polymorphism with the occurrence of cardiovascular events during long-term follow-up in patients with myocardial infarction.

   Material and methods. The study included 218 patients with acute infarction (MI), mean age 57.7 ± 9.9 years (M ± SD). After clinical examination and preparation, patients urgently underwent coronary angiography followed by percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG). All patients underwent determination of the rs2305948 VEGFR2 allelic variant by polymerase chain reaction. The duration of long-term follow-up of these patients was 9 years (from 2015 to 2024).

   Results. It was determined that during long-term follow-up, patients with rs2305948 VEGFR (C/T and T/T), in contrast to patients with rs2305948 VEGFR (C/C), were more likely to experience cardiovascular death, recurrent acute coronary syndrome (ACS), recurrent revascularization and a combined end point (cardiovascular death, recurrent ACS, coronary stent/bypass thrombosis, acute ischemic cerebrovascular accident, repeated myocardial revascularization). Using multivariate analysis, it was determined that the occurrence of cardiovascular death during long-term follow-up is directly influenced by the Charlton comorbidity index (p < 0.001) and rs2305948 VEGFR2 (C/T and T/T) (p = 0.030). The onset of a combined endpoint is directly determined by the Charlton comorbidity index (p = 0.014) and rs2305948 VEGFR2 (C/T and T/T) (p = 0.034) and vice versa by subsequent outpatient treatment with high doses of statins (p < 0.001).

   Conclusions. The presence of rs2305948 VEGFR (C/T and T/T) in patients with MI increases the likelihood of cardiovascular death by 2.82 times and the combined endpoint by 2.10 times during long-term follow-up (9 years).

Selain disebabkan oleh asupan gizi balita tidak sesuai kebutuhan, pendidikan keluarga yang kurang turut menyebabkan stunting di suatu daerah meningkat. Pendidikan tentang asupan gizi balita bukan hanya tanggung jawab ibu, melainkan ada peran kader posyandu sebagai kelompok yang paling dekat untuk menyampaikan informasi. Studi ini bertujuan untuk mengetahui perbedaan peran kader posyandu dalam mengedukasi pemenuhan kebutuhan gizi balita di daerah dengan stunting tinggi dan rendah. Studi berlokasi di Sumedang sebagai penyumbang stunting tertinggi Jawa Barat, tepatnya di Desa Margamukti sebagai daerah dengan stunting rendah dan Desa Mulyasari sebagai daerah dengan stunting tinggi. Penelitian perbandingan ini merupakan penelitian kuantitatif yang menggunakan desain cross-sectional dengan teknik total sampling yaitu 70 responden yang terbagi ke dalam 35 responden di daerah stunting tinggi dan 35 responden di daerah stunting rendah. Kriteria sampel adalah kader posyandu yang terdaftar di kantor desa. Data dikumpulkan menggunakan kertas kuesioner “Evaluasi peran kader posyandu dalam mengedukasi pemenuhan kebutuhan gizi balita” dan dianalisis dengan uji mann whitney. Hasil penelitian menunjukkan bahwa terdapat perbedaan signifikan pada frekuensi dan metode penyuluhan dengan p-value 0,001 dan 0,008 < a = 0,05, maka dari itu tidak ditemukan perbedaan lain yang dapat menunjukkan adanya perbandingan peran kader di daerah dengan stunting tinggi dan rendah.
