Published: December 2023

Population growth has an impact on increasing the need for land use. The availability of land for settlement development in urban areas is very limited, so that there are people who occupy land that is unsuitable. The coastal area of Semarang City is located on the northern outskirts of the city, indicating an increase in settlement areas. The characteristics of coastal areas that have flat morphology and border the sea are flood-prone areas. This study aims to analyze land suitability for settlement development in the coastal area of Semarang. Suitability based on land capability, and completeness of settlement facilities. To provide information about settlement development locations that are safe and have complete facilities. Settlement development locations in accordance with spatial planning documents and land availability. Using quantitative descriptive methods and spatial analysis with geographic information systems and remote sensing imagery as spatial data. The stages of analysis include analysis of physical aspects, analysis of land capability, analysis of settlement service levels and analysis of land suitability for settlement development. The results showed that currently there are 1696.80 ha of suitable land for the development of settlements in the Semarang Coastal area. Most of them are in Genuk District (60.88%) and Tugu District (26.89%). The research findings can be used as government considerations in compiling spatial policy recommendations related to Sustainable Settlement Development in the Coastal Areas of the Semarang City.

Published: December 2023

Economic growth in Central Java Province is currently being driven by the rapid acceleration of investment, leading to the development of cities and districts. However, the measurement of regional competitiveness is currently limited to analysing regional capabilities in development. This condition creates a situation where regencies and cities compete with each other without considering the functions and roles of interconnected regions. Therefore, there is an urgent need to understand and utilize regional competitiveness within the framework of the regional system in order to support the policies of the Central Java Province. This study adopts a quantitative approach to analyse the stages of regional development, which are identified based on competitiveness starting from basic requirements as a factor-driven, efficiency-driven, and innovation factor. Using this approach, we aim to classify the functions and roles of cities and districts within the regional system in Central Java. The data for this study was obtained through the distribution of questionnaires in 35 districts and cities in Central Java Province, as well as interviews with stakeholders from both the regions and the provinces. The findings of this study reveal that cities and regencies have different stages of competitiveness, with some focusing on driving innovation and strengthening driving factors, while neglecting efficiency. Spatially, cities exhibit a higher level of competitiveness; however, most urban districts have not incorporated the role of the region in the planning of a sustainable regional system.

Published: December 2023

Regional innovations play a crucial role in driving economic development and enhancing regional competitiveness. Innovation is the main raw material and support for competitiveness, which makes regions with high innovation must also have high competitiveness. Regional innovation is shaped by factors such as innovation policy, knowledge generation, knowledge application, and socio-cultural elements. This research aims to examine regional innovation and its relationship with competitiveness based on spatial distribution. The method employed is quantitative descriptive analysis, utilizing statistical data on regional innovation obtained through a questionnaire distributed to local governments in 35 districts and cities. Additionally, a spatial analysis was conducted to compare the innovation scores and competitiveness. The research findings indicate a consistent alignment between the innovation profile and regional competitiveness. However, there are also anomalous areas demonstrating divergent outcomes. This suggests that while innovation is a significant contributor to regional competitiveness, it is not the sole determinant influencing it.

Regional development in an area will have consequences for the health status of the surrounding community. This paper discusses the adequacy of community health center (CHC) facilities in taking an important role in managing health disasters such as the Covid-19 pandemic. Covid-19 is one of the most infectious environmental-based diseases. The research objective was to spatially identify the availability of CHC and their relationship to Covid-19 cases during the pandemic. Ecological studies are used with a spatial approach. The population in this study were all sub-districts in Magelang District with a total sampling. Spatial analysis makes use of the QGIS and Geoda applications. The results showed that there was grouped spatial autocorrelation (Moran’s I = 0.089, Io = 0.05) between CHC in Magelang. Covid-19 in Magelang residents has a positive autocorrelation with CHC (Moran’s I = 0.248, Io = 0.05) and forms a cluster pattern. The spatial lag regression further clarifies that there is a spatial autocorrelation between the two variables (Coef: -0.175; p value= 0.569), and the Covid-19 variable has a significant influence on the CHC (p=0.0022). Analysis using the Local Indicator Spatial Association (LISA) method found that Ngluwar Sub-district is in the High-High quadrant, while Mungkid Sub-district is in the Low-High quadrant and the other sub-districts are not significant. Spatial pattern heterogeneity is formed in CHC and there is a spatial autocorrelation relationship between Covid-19 cases and CHC. Systematic planning is needed to overcome the adequacy of the CHC to help improve the quality of public health.
Spatial Pattern of Urban Heat Island to Enhance Urban Cooling Ecosystem Services in the Post-Pandemic Era
Authors: Rini Erma F.
Published: December 2023

Urbanization, followed by reduced green space, often leads to increased land surface temperatures (LST), which is also known as the urban heat island (UHI) effect. Urban cooling ecosystem services provided by forests and parks play a crucial role in reducing the UHI effect (which is reflected in LST) and improving the liveability and sustainability of cities. The pandemic has changed many people’s views about the importance of ecosystem services to their well-being. The post-pandemic era is a turning point for infrastructure and environmental improvements to increase ecosystem services’ benefits. This study aims to look at the potential for increasing ecosystem services’ benefits through the provision of urban forests and parks based on UHI conditions in Surakarta city. In this study, UHI was identified from LST based on Landsat 8 and Landsat 9 remote sensing images. The spatial pattern of the UHI was analyzed based on block units using road boundaries using cluster and outlier statistical spatial analysis. In formulating alternatives to provide urban forests and parks, we also interviewed stakeholders from a village revitalization program in Kampung Mojo, Surakarta city. The results show that after the pandemic, in a revitalized neighborhood, the surface temperature was still high. The revitalization program did not include the provision of parks because the basic issue of this program is land ownership legality. Nevertheless, the UHI spatial pattern provides evidence that the provision of urban forests and parks is needed on the central and southern sides of Surakarta city to enhance urban cooling ecosystem services.

Authors: Dewi Santy P. , Mussadun Mussadun
Published: December 2023

The existence of public open space is essential for a city, not only to beautify the visual area but also as a space for community interaction, a place for play, recreation, and greening the city. Tirto Agung Park is one of the public open spaces built by the Semarang City Government, which serves the urban community, mainly people of Tembalang and Banyumanik Districts. The park surrounding area is livelier, so the government claims this park is a thriving public space. However, the park leads to the emergence of cafes, shophouses, apartments, and street vendors, making some areas crowded. Most park visitors are people from outside, which raises the question of how attached the people who live around are to the park’s existence. Therefore, this research aims to identify the green-placemaking of Tirto Agung Park by determining the park’s ability to accommodate the community. Placemaking is an effort to strengthen the relationship between public space and visitors determined from several variables, such as access and linkages, sociability, uses and activities, comfort, and image. The research method used is quantitative, and data collection methods through field observation and questionnaires. The analytical methods are descriptive quantitative and spatial analysis methods to determine the activity and space use around the park, the relationship between public open spaces and the community (behavioral mapping), and mapping the components of placemaking. The results showed that placemaking has occurred in Tirto Agung Park, but some aspects still need improvement to enhance the placemaking further.

Published: December 2023

The conceptual foundations of monitoring the state’s food security system under the conditions of global turbulence have been deepened. It was determined that the set of indicators of the state of food security used in national practice is imperfect. It is emphasized that the totality of indicators cannot objectively contribute to identifying potential threats to sustainable development and adopting effective management decisions. Attention is focused on the need to consider the impact of other components, including the issues of the accessibility, availability, quality, and safety of food products, as well as their resilience and adaptability. The hypothesis regarding the direct relationship between the degree of compliance of agricultural production in the country with sustainable development principles and the overall level of economic accessibility of food has been proved. The established and mathematically proven direct relationship between the indicators made it possible to emphasize the need to raise the population’s living standards. This is necessary to reduce the negative impact of the production of agricultural products on the environment, which results from the understanding by consumers of the need to satisfy not only basic needs but also to preserve natural resources for future generations. It is mathematically proven that in countries with a high level of economic accessibility of food, the compliance of agricultural production with sustainable development principles has a high level and is strongly correlated with economic factors. In countries with medium and low indicators of economic accessibility of food, such a relationship does not have statistical significance. The conclusions drawn are useful for practical use in conditions of global economic turbulence.

Published: December 2023

The study explores the world of green finance within the context of the Georgian financial market, focusing on the influence of regulatory initiatives and market practices. Green finance, driven by sustainability goals and environmental responsibility, has gained prominence globally. In Georgia, this phenomenon has been exemplified by the introduction of sustainability bonds and the integration of ESG factors into financial institutions’ strategies. The research question centers on understanding how regulatory initiatives and market practices impact the growth and effectiveness of green finance in Georgia. The hypothesis posits a positive correlation between the adoption and implementation of regulatory initiatives (such as green taxonomies and ESG guidelines) and the growth and impact of green finance. Through a comprehensive survey of 200 loan officers in Georgian commercial banks, the study gathers insights into perceptions and attitudes regarding sustainability bonds, ESG integration, and green taxonomies. The majority of respondents express optimism about the positive influence of these factors on green finance.

Published: December 2023

The article examines the state of development, problems, and needs of innovative management in the hospitality industry. Based on research results using the example of EU countries, the dominance of a group of countries with the lowest indicators of workforce employment in the hospitality industry across all types of activities (59.3%) has been identified. The presence of highly developed countries in this group indicates the activation of innovative management activities in the hospitality industry. Accordingly, the directions of modern digital trends in the hospitality industry have been studied and schematically presented. Analyzing consumer behavior in the hospitality industry, changes have been observed due to tourists’ insufficient financial support: an increase in the number of trips during off-peak periods (especially in Slovakia (186.79%), Ireland (102.51%), Austria (79.58%)); a preference for budget-friendly travel destinations (for example, Serbia, Turkey, Bulgaria). The study justifies the need for the development of innovative management in the hospitality industry and schematically presents a possible option for its provision, highlighting the need for ongoing research to identify user needs in hospitality services and explore alternative ideas to meet those needs.

Published: December 2023

In the second half of 2021 - the first half of 2023, the EU electricity markets were under unprecedented pressure caused by soaring gas prices and aggravated by other fundamental factors. This period corresponds to the energy crisis in the EU electric power sector. However, all EU electricity markets responded to the energy crisis differently. This paper proposes a methodology for revealing the energy crisis in the electricity market, which is based on the tools of descriptive statistics, explanatory data analysis and k-means clustering which allows to identification duration and phases of the energy crisis such as escalation, peak, and recovery phases. Using this methodology, the energy crisis was identified in the EU electricity markets (by separate bidding zones), and as a result, the starting and ending points of the energy crisis, as well as the changing by phases, were determined. Additionally, the use of hierarchical and agglomerative clustering methods made it possible to divide all EU electricity markets into 9 clusters by the evolution of the energy crisis and identify unaffected, resilient vulnerable markets to the energy crisis, and markets with their own dynamics.

Published: December 2023

While there is a burgeoning body of literature investigating the economic implications of participation in GVCs on growth and other key macroeconomic indicators, there remains a paucity of studies that specifically explore how natural resources interact within the context of GVCs in both developing and developed countries. This paper seeks to address the current gap by conducting an investigation into the impact of resource-based GVC participation, specifically for the industries of fuels and minerals, on the growth of value-added. Utilizing a unique dataset that spans the period from 1990 to 2016 and contains 133 countries, we employ the fixed effects method to capture unobserved individual heterogeneity. Our empirical findings reveal that, for our full sample, mineral (fuels) backward (forward) GVC participation has a positive and significant impact on the growth of the industry. Also, forward GVC participation exerts a favorable influence on value-added growth in the fuels and minerals sectors in developed countries. Finally, participating in minerals backward participation favors the mineral value-added growth in only developing countries.

Published: December 2023

The article examines the role of innovations in the development of the national economy. The dynamics of budgetary financing of strategic priorities of innovation and technology transfer activities in Ukraine for 2019-2021 is analyzed. The priorities, the support of which is increasing annually, and the priorities where funding is decreasing, are identified. It is proposed to carry out a predictive assessment of innovative projects using the clustering procedure. The implementation of the proposal is highlighted on the example of innovative developments in the strategic priority area "Widespread use of cleaner production technologies and environmental protection". A point system for expert evaluation of the planned scientific results of the innovation and the scientific potential of the performers is shown. The indicators that have the greatest impact on the forecast efficiency are identified. The results of clustering of innovative developments according to certain indicators are presented. The statistical indicators of average scores in each cluster are analyzed. Significant differences between the clusters have been determined using the non-parametric Mann-Whitney test. The carried out clustering provides reasonable recommendations on the feasibility of financing an innovative project based on predictive expert assessments.

Published: December 2023

The important article substantiates the peculiarities of environmental tax administration in Ukraine and defines its importance in ensuring an ecologically oriented economy. It has been proven that from 2016 to 2020 there is an increase in emissions of pollutants into the atmosphere by more than 10.5%. A thorough analysis of the payment of the environmental tax to the relevant budget was carried out and a close relationship between the number of emissions of polluting substances and the rates of this tax was determined. It has been proven that in Ukraine the environmental tax does not ensure the performance of one of the main functions, namely the preservation of the natural environment. This situation is due to the relatively low rates of this tax, as well as the lack of an effective mechanism for controlling emissions of pollutants. One of the main directions of solving this problem is to use the experience of European countries in diversifying the tax rates under study depending on the type and volume of pollutant emissions.

The mining and technological features of the Gusarovsky deposit of molding sands mining under the conditions of technological limitations of the existing enterprise have been studied. The granulometric composition of balance reserve sands, as well as overburden rocks, was analyzed. In order to obtain a high-quality commercial product with a minimum content of fine and clay particles from the initial rock mass of the surface and watered ledges, the parameters of the hydromechanized complex were substantiated by mining and processing. The calculation is based on the three most available options for filling the mining and processing complex (MPC). To substantiate the rational parameters of the MPC and ensure the purification of the commercial product from fine impurities, a graphical characteristic of the hydraulic vertical classifier GKCD2000 was constructed when supplying clean water and at a slurry concentration of 10%. The graphical characteristics of hydraulic transport systems were constructed in accordance with the design diagrams of the accepted variants of the complex. To substantiate the rational parameters of the pumping station, the characteristics of the mining and processing complex were constructed when pumping clean water and slurry at a concentration of 10%. For the first time, the rational parameters of the technological complex of mining and processing, consisting of a suction dredger – a transport slurry pipeline – and a vertical hydraulic classifier GKCD2000, have been substantiated. The development of a technological complex of mining and processing will allow the existing enterprise to continue developing the deposit and obtaining high-quality commercial products under the conditions of technological limitations.

Published: December 2023

The article considers the mechanism of possible full supply of strategic resources for the purpose of implementing the concept of sustainable development. Two main approaches to the accumulation of resources are indicated: i) the first approach, aimed at maintaining a strategic stock of energy resources, which involves the concentration of resources to ensure the stability and security of energy supplies; ii) the second approach consists in the accumulation of financial assets through the receipt of income and allows the formation of a financial reserve. In the case of the first approach, the country like the United States strategically accumulated crude oil reserves, exemplified by the establishment of the Strategic Petroleum Reserve (SPR) in the 1970s. The percentage ratio of US crude oil exports relative to their daily oil consumption in the United States from 1980 to 2023 was calculated and detailed in the research, with trends such as a decline of 1% in 2005 and a subsequent increase of 156% in 2023 being revealed, and the impact of technological and geopolitical factors on these changes was determined.
SWCNT-Si photodetector with voltage-dependent active surface
Authors: Capista Daniele , Lozzi Luca , Di Bartolomeo Antonio , Giubileo Filippo , Martucciello Nadia , Passacantando Maurizio
Published: December 2023

New works on Carbon Nanotubes-Silicon MIS heterostructures showed that the presence of thickness inhomogeneities in the insulating layer across the device can be exploited to increase their functionalities. In this work, we report the fabrication and characterization of a device consisting of a Single-Walled Carbon Nanotube (SWCNT) film onto an n-type silicon substrate where the nitride interlayer between the nanotubes and the silicon has been intentionally etched to obtain different thicknesses. Three different silicon nitride thicknesses allow the formation of three regions, inside the same device, each with different photocurrents and responsivity behaviors. We show that by selecting specific biases, the photoresponse of the regions can be switched on and off. This peculiar behavior allows the device to be used as a photodetector with a voltage-dependent active surface. Scanning photo response imaging of the device surface, performed at different biases, highlights this behavior.

Objective

To describe the reusable transformation process of electronic health records (EHR), claims, and prescriptions data into Observational Medical Outcome Partnership (OMOP) Common Data Model (CDM), together with challenges faced and solutions implemented.

Materials and Methods

We used Estonian national health databases that store almost all residents’ claims, prescriptions, and EHR records. To develop and demonstrate the transformation process of Estonian health data to OMOP CDM, we used a 10% random sample of the Estonian population (n = 150 824 patients) from 2012 to 2019 (MAITT dataset). For the sample, complete information from all 3 databases was converted to OMOP CDM version 5.3. The validation was performed using open-source tools.

Results

In total, we transformed over 100 million entries to standard concepts using standard OMOP vocabularies with the average mapping rate 95%. For conditions, observations, drugs, and measurements, the mapping rate was over 90%. In most cases, SNOMED Clinical Terms were used as the target vocabulary.

Discussion

During the transformation process, we encountered several challenges, which are described in detail with concrete examples and solutions.

Conclusion

For a representative 10% random sample, we successfully transferred complete records from 3 national health databases to OMOP CDM and created a reusable transformation process. Our work helps future researchers to transform linked databases into OMOP CDM more efficiently, ultimately leading to better real-world evidence.
Quasar Sightline and Galaxy Evolution (QSAGE) – III. The mass–metallicity and fundamental metallicity relation of z ≈ 2.2 galaxies

Published: December 2023

We present analysis of the mass–metallicity relation (MZR) for a sample of 67 [O iii]-selected star-forming (SF) galaxies at a redshift range of z = 1.99−2.32 (zmed = 2.16) using Hubble Space Telescope Wide Field Camera 3 grism spectroscopy from the Quasar Sightline and Galaxy Evolution survey. Metallicities were determined using empirical gas-phase metallicity calibrations based on the strong emission lines [O ii]3727, 3729, [O iii]4959, 5007 and Hβ. SF galaxies were identified, and distinguished from active-galactic nuclei, via Mass–Excitation diagrams. Using z ∼ 0 metallicity calibrations, we observe a negative offset in the z = 2.2 MZR of ≈−0.51 dex in metallicity when compared to locally derived relationships, in agreement with previous literature analysis. A similar offset of ≈−0.46 dex in metallicity is found when using empirical metallicity calibrations that are suitable out to z ∼ 5, though our z = 2.2 MZR, in this case, has a shallower slope. We find agreement between our MZR and those predicted from various galaxy evolution models and simulations. Additionally, we explore the extended fundamental metallicity relation (FMR) which includes an additional dependence on star formation rate. Our results consistently support the existence of the FMR, as well as revealing an offset of 0.28 ± 0.04 dex in metallicity compared to locally derived relationships, consistent with previous studies at similar redshifts. We interpret the negative correlation with SFR at fixed mass, inferred from an FMR existing for our sample, as being caused by the efficient accretion of metal-poor gas fuelling SFR at cosmic noon.

Published: December 2023

Objectives:

Our purpose was to explore the effect of remifentanil on acute and chronic postsurgical pain after cardiac surgery.

Methods:

Randomized controlled trials (RCTs) were retrieved in electronic databases such as PubMed, Cochrane Library, CNKI databases, Scopus, and Web of Science. A systematic review, meta-analysis, trial sequential analysis (TSA) was performed. Basic information and outcomes were extracted from the included studies. The primary outcome was chronic postsurgical pain. Secondary outcomes were scores of postsurgical pain and morphine consumption within 24 hours after cardiac surgery. Our risk of bias assessment was based on the Cochrane risk of bias tool version 2 (ROB 2.0). The overall quality of the evidence was rated using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system.

Results:

Seven studies consisting of 658 patients were enrolled in the meta-analysis. A single study had a high risk of bias and two studies had a moderate risk of bias. The incidence of chronic postsurgical pain (four studies [415 patients]; RR, 1.02 [95% CI, 0.53-1.95]; P =0.95; I2=59%; TSA-adjusted CI, 0.78-1.20) and the postsurgical pain score (two studies [196 patients]; MD 0.09 [95% CI, -0.36-0.55]; P =0.69; I2=0%; TSA-adjusted CI, -0.36-0.55）were not statistically different between the two groups. However, morphine consumption (six studies [569 patients]; MD 6.94 [95% CI, 3.65-10.22]; P<0.01; I2=0%; TSA-adjusted CI, 0.00-0.49) was higher in the remifentanil group than in the control group.

Discussion:

There was not enough evidence to prove that remifentanil can increase the incidence of chronic postsurgical pain after cardiac surgery, but interestingly, the results tended to support a trend toward increased complications in the intervention group. However, there was moderate-certainty evidence that the use of remifentanil increases the consumption of morphine for analgesia, and more direct comparison trials are needed to inform clinical decision-making with greater confidence.
Opening Up the Continuing Professional Development Imagination: Bringing the Clinical Workplace Into View
Authors: Rowland Paula
Published: December 2023

This Foundations paper introduces the “Working as Learning Framework (WALF)” to the continuing professional development community. Developed by researchers in the domain of workplace learning, the WALF draws upon theories and concepts from economics, sociology of work, and sociocultural theories of learning. The Framework provides conceptual tools to analyze interconnections between workplaces, the organization of work tasks, and learning. Through these interconnections, the Framework introduces the concepts of “expansive learning environments” and “restrictive learning environments.” This paper provides an overview of the WALF before discussing possible implications for continuing professional development educators and researchers. Ultimately, this Foundations paper invites readers to engage with the rich scholarship on workplace learning informed by sociocultural concepts of learning and complemented by research on work and workplaces.
Recasting Assessment in Continuing Professional Development as a Person-Focused Activity
Authors: Toews Helen , Pearce Jacob , Tavares Walter
Published: December 2023

In this article, we examineassessmentas conceptualized and enacted in continuing professional development (CPD). Assessment is pervasive throughout the life of an individual health professional, serving many different purposes compounded by varied and unique contexts, each with their own drivers and consequences, usually casting the person as theobjectof assessment. Assessment is often assumed as an included part in CPD development conceptualization. Research on assessment in CPD is often focused on systems, utility, and quality instead of intentionally examining the link between assessment and the person. We present an alternative view of assessment in CPD as person-centered, practice-informed, situated and bound by capability, and enacted in social and material contexts. With this lens of assessment as an inherently personal experience, we introduce the concept ofsubjectification,as described by educationalist Gert Biesta. We propose that subjectification may be a fruitful way of examining assessment in a CPD context. Although the CPD community, researchers, and educators consider this further, we offer some early implications of adopting a subjectification lens on the design and enactment of assessment in CPD.
Cutaneous Coccidioidomycosis

Coccidioidomycosis is an infectious primary pulmonary disease caused by two highly virulent fungi, Coccidioides immitis and C. Posadasii. Coccidioidomycosis spp. are endemic to the southwestern USA, Central America, and South America with infection predominating in the summer and fall seasons. The disease commonly presents with flu-like symptoms. Cutaneous manifestations are rare and are a sign of a more serious infection with poorer outcomes. In this case, a 60-year-old female presented to the dermatology clinic with a 3-month history of a mild, non-pruritic, erythematous rash located on her proximal arms and legs. Two punch biopsies were obtained, and she was found to have a non-endemic case of disseminated coccidioidomycosis.
A Case of Uncommon S100-Negative CD1a-Positive Histiocytosis in a 9-Year-Old Boy: Clinical Presentation, Histopathologic Features, and Successful Treatment Approach
Authors: Zhu Jiaping , Sun Jianfang
Published: December 2023

Immunohistochemically, histiocytosis differentiating into Langerhans cells is typically characterized by the expression of CD1a, S100, and varying degrees of Langerin. However, CD1a-positive but S100-negative histiocytosis is extremely rare in clinical practice. We present a case of a 9-year-old boy with multiple erythematous to brown dome-shaped nodules. Histopathologic examination revealed dermal infiltrates of histiocytic cells, exhibiting a distinctive immunohistochemical profile of CD68+, S100−, CD1a+, and Langerin−. This exceptional case may contribute to our understanding of the etiology and differentiation processes of histiocytic proliferative disorders.

Published: December 2023

Purpose: To report the case of severe bilateral retinal vascular occlusion in a patient with hyperoxalosis and chronic renal failure.

Methods: Observational case report. Medical and imaging records were retrospectively reviewed. The patient was imaged with ultra-widefield (UWF) fundus photography and fluorescein angiography (UWF-FA), cross sectional and en face spectral-domain optical coherence tomography (SD-OCT), and OCT angiography.

Results: A 32-year-old diabetic patient receiving peritoneal dialysis was referred because of severe vision loss. UWF color fundus photography showed diffuse sclerotic retinal vessels and diffuse intraretinal crystals in both eyes. UWF-FA illustrated near-complete retinal vascular occlusion and capillary wipe out in both eyes. SD-OCT demonstrated diffuse inner and middle retina thinning in both eyes and multiple intraretinal hyperreflective foci consistent with crystalline deposits in all retina layers of both eyes. OCT angiography revealed severe capillary and large vessel non-perfusion in the superficial and deep retinal capillary plexus of each eye. The serum oxalate levels were increased at 28 µmol/L (reference range < 2 µmol/L) and genetic testing was positive for a heterozygous mutation of the AGXT (Alanine-Glyoxylate Amino Transferase) gene that causes type 1 autosomal recessive primary hyperoxaluria.

Conclusion: A diagnosis of hyperoxalosis causing severe retinal vascular occlusion was rendered. Hyperoxalosis was the result of multiple factors including heterozygous AGXT mutation, chronic renal failure insufficiently treated with peritoneal dialysis, and a diet high in oxalate. This case highlights the importance of ruling out retinal oxalosis in patients on peritoneal dialysis in order to initiate prompt hemodialysis and prevent severe retinal vascular occlusion.
RADIATION RETINOPATHY AND BENIGN LYMPHOPROLIFERATIVE ORBITAL TUMOR PRESENTING 47 YEARS AFTER TREATMENT OF HEREDITARY RETINOBLASTOMA

Published: December 2023

Purpose:

The objective of this study was to better understand the onset of radiation retinopathy and secondary orbital tumors in the setting of retinoblastoma treated with radiation and chemotherapy.

Methods:

This was a case report.

Results:

Here, the authors present a 48-year-old woman with a history of bilateral hereditary retinoblastoma after enucleation of the left eye and radiation therapy to the right eye along with systemic chemotherapy. She underwent bladder leiomyosarcoma resection at the age of 24 years. In 2020, she presented with significantly delayed radiation retinopathy complicated by cystoid macular edema, and bevacizumab injections were initiated. An incidental benign lymphoproliferative tumor in the right lacrimal gland was found on B-scan ultrasound and was successfully excised.

Conclusion:

It is rare for radiation retinopathy to present with significant delay after local radiation treatment, with only two other cases found in the literature describing a similar late onset. In addition, there have been no other published cases of a secondary benign lymphoproliferative tumor in the setting of retinoblastoma treated with radiation and chemotherapy.
