Published: December 2023

Background The Chief Medical Officer (CMO) for England’s 2021 report showed ecological correlations between small areas in England that were coastal and worse population health outcomes. A burgeoning social epidemiological literature shows that where you grow up plays a role in adulthood health, but there is scant research on how coastal areas impact health.Methods In this retrospective, population-based cohort study (the UK Household Longitudinal Study [UKHLS]), we included all people who had completed a youth questionnaire at age 15 years (or next closest age 10-14), linked to community type (inland or coastal) by lower-super output area (LSOA) of residence in adolescence, and who had responded to at least one adult (age 16+) UKHLS questionnaire during eleven waves of follow-up (2009-2022). The analysis fitted associations of five health outcomes with living in a coastal community in adolescence using regressions models with fixed effects at the individual and study wave, adjusting for clustering of individuals within LSOAs and longitudinal study weighting. We also tested for effect modification between coastal residence and community deprivation (Townsend index).Findings Of 4,921 adolescents aged 10–15 years (at baseline) with follow-up young adult health data, approximately 15.5% resided in a coastal community in adolescence. The median age at baseline was 14.8 years (SD 0.6), the median follow-up was 3.7 waves (range 1-11), and across all 18,324 observations: 22.3% self-reported their health as excellent, 40.4% very good, 28.1% good and 9.3% fair or poor, 15.3% reported a long-standing impairment, illness or disability (LSIID), with mean GHQ-12 scores 11.5 (SD 6.0), mean SF-12 mental component scores (MCS) 46.1 (SD 11.5) and mean SF-12 physical component scores (PCS) 54.9 (SD 6.8). When only community type was fitted in age-adjusted models, coastal community residence was associated with a 1.23 (95% CI: 1.01, 1.49) higher odds of lower SRH and 1.41 (1.03, 1.92) higher odds of LSIID, and no association with GHQ-12, MCS or PCS scores. However, when community deprivation was taken into consideration, all health outcomes except PCS showed worse health in increasingly more deprived communities, and to a greater extent in the most deprived communities that are coastal.Interpretation Young people who grow up in deprived coastal communities have worse health outcomes in young adulthood, than those who grow up in equivalent inland communities. This is especially the case for mental health and wellbeing outcomes, which themselves are often embedded in early life and cause poor physical and mental health in later life. Future research and policy should endeavour to determine what it is about living in a coastal community in adolescence that possibly triggers poor health.Funding UK Economic and Social Research Council.
Identification of Congressional Witness Political Party: A Graph Theoretic Approach
Authors: Coil Collin , Bruckner Caroline L. , O'Connor Karen , Williamson Natalie
Published: December 2023

Despite thousands of witnesses appearing before congressional committees each year, witness function and impact are rarely discussed in the literature. Moreover, the complexity of committee witness selection practices and their reflection of witness partisanship is understudied. Even scholars who have examined the impact of witnesses have done so with flawed understandings of witness selection rules and practices, resulting in misguided analyses. This paper sets forth "witness partisanship mapping," a generalizable graph theoretic technique for the identification of a witness’s selecting party. This approach considers the rules and practices regarding witness selection. We use data resulting from our methodology to produce three new insights concerning the partisanship of congressional witnesses and the role that they play in the legislative process.
Populism and the pandemic: The politicization of COVID-19 and cleavage agency among populist radical right parties
Authors: Volk Sabine , de Jonge Léonie , Rensmann Lars
Published: December 2023

This paper explores the politicization of the COVID-19 pandemic and cleavage agency among populist radical right parties (PRRPs) across the European Union (EU). Conceptualizing PRRPs as meaning-making agents, we ask if and to what extent they have reshaped socio-political conflicts and cleavage politics through COVID-19 issue entrepreneurship. To this end, we draw on a small-N comparative analysis of three country and party cases from across Europe, covering different regions within the EU as well as different institutional settings, with PRRPs being either in opposition (AfD in Germany, FvD in The Netherlands) or in power (PiS in Poland). We conduct a critical discourse analysis of party mobilizations and discursive framing in these three country contexts based on an original qualitative corpus including party media and publications, manifestos, political speeches, and social media posts, published in the context of election campaigns in 2020/21. Our findings indicate that despite variation across cases, all PRRPs studied in this paper contributed to consolidating a new politico-cultural super cleavage between liberal pluralism and authoritarian populism, which ideologically frames all societal conflicts in terms of an antagonism between alleged "totalitarian elites" and the (values of the) "democratic people".
“It’s funny if the group says so”: Group Norms Moderate Disparaging Humor Appreciation
Authors: Argüello-Gutiérrez Catalina , Carretero-Dios Hugo , Willis Guillermo B. , Moya Miguel
Published: December 2023

We tested the hypothesis that group norms would have an effect on humor appreciation, specifically on ingroup disparaging humor. In this study (N = 195), participants were exposed to two humor conditions (neutral or ingroup disparaging humor) and to two group norms regarding humor appreciation (favoring or rejecting). Favoring group norm had a direct effect on the funniness scores. Moreover, an interaction effect of group norm and type of humor was found on the humor appreciation. When the group norm was rejecting, appreciation of the two different types of humor was different, whereas in the favoring group norm, no statistically significant differences were observed. Additionally, for the disparaging humor exposure, a favoring group norm promoted a greater acceptation of the stereotypical characteristics presented in the disparaging humor as realistic and representative of the ingroup. These results suggest that group norms act as important contextual information that influences disparaging humor appreciation.
The Effect of Moral Foundations on Intergroup Relations: The Salience of Fairness Promotes the Acceptance of Minority Groups
Authors: Argüello-Gutiérrez Catalina , Lopez-Rodriguez Lucia , Vazquez Alexandra
Published: December 2023

Previous research suggests that moral foundations have consequences for intergroup relations, but the evidence is mostly correlational and gathered mainly in north American countries. This work aimed to replicate the conceptual findings in the European context and test the effects of manipulating a moral framing on the perceived (im)morality of minority groups, willingness to defend their rights collectively and support for anti-immigration policies. A correlational study showed that binding and individualizing foundations contributed to predict support for anti-immigration policies and willingness to participate in collective actions for immigrants’ rights. A follow-up experiment suggested that emphasizing the benefits for society of fairness—an individualizing foundation—(vs. authority—a binding foundation) may improve intergroup evaluations, increase collective action intentions, and reduce support for anti-immigration policies. Although a second preregistered experiment could not replicate the results, complementary analyses suggested some positive effects of fairness compared with the control and authority conditions. These results open a path to investigate whether a fairness moral reasoning might improve attitudes toward immigrants.
Global inequalities in weather forecasts
Authors: Linsenmeier Manuel , Shrader Jeffrey G.
Published: December 2023

Global weather forecasts are of great economic value for society, but geographical differences in forecast accuracy can create new - and potentially exacerbate existing - economic inequalities. Regional differences in forecast accuracy are particularly relevant if weather forecasts are considered as an important tool to help reduce the negative effects of future climate change such as mortality from extreme temperature events. In this paper, we provide a comprehensive global analysis of the accuracy of short-term numerical weather predictions of temperature and relate our findings to both existing economic inequalities and inequities in global weather monitoring infrastructure. We report three main results: First, temperature forecasts are currently substantially more accurate in high income countries than in low income countries. A seven-day-ahead forecast in a high-income country is on average more accurate than a one-day-ahead forecast in a low income country. Second, while forecast accuracy has improved steadily between 1985 and the present - with the largest increases in the 1990s - there is a persistent gap between high income and low income countries. Third, the infrastructure for weather observations is highly unequally distributed across countries, with fewer land-based weather stations and radiosondes in poorer countries. These inequalities grow even larger when lower reporting rates are taken into account. Remedying these differences in infrastructure would help close the forecast accuracy gap.
Glyphosate-based forest management in New Brunswick: regulatory context, socio-environmental health, and industry discourse
Authors: Sapinski Jean Philippe , Surette Céline
Published: December 2023

Forestry is a major economic sector in New Brunswick. For many years, forestry management practices have been subject to controversies, and different positions persist. Aerial spraying of glyphosate as part of forest management practices emerged over the last decade as a contentious issue in the province. In this chapter, we present an analysis of the narrative created by the forest industry in support of glyphosate use. We argue that premier Blain Higgs’ policy record is coherent with this narrative that reconciles the oft-heard opposition between “the environment” and “the economy” through ever-more advanced technologies such as glyphosate. The first section provides background information on glyphosate use in forest management in NB. In the second section, we discuss the regulatory context of glyphosate use. The third and fourth sections present a structural discourse analysis of a small corpus of industry discourse, mainly focused on the presentation by the company JD Irving at the 2021 public hearings held by the Standing Committee on Climate Change and Environmenta Stewardship. We conclude by looking back at the Higgs government’s (in)action following the public hearings that hints at a causal link between industry discourse and government policy.
Forty Years of Social and Demographic Change in the Netherlands: An Integrated Harmonized Survey Data Set, 1979-2022
Authors: Kalmijn Matthijs , Henkens Kene
Published: December 2023

This project presents a new data set that can be used for describing long-term social and demographic change in the Netherlands. The data set is based on harmonized surveys previously collected by the Netherlands Institute for Social Research (SCP) and Statistics Netherlands (CBS) from 1979 to 2022. Differences in measurement and design are discussed, harmonization procedures are explained, and the data file with common variable names and value labels is documented. The code is publicly available allowing researchers to obtain the harmonized data (in a companion paper). Detailed tables are presented for all characteristics in the harmonized data set, both for the entire population 21+ and for the working-age population 21-64. The data set provides descriptive information that is often missing or incomplete in register data and retrospective surveys.
Effects of remote work on population distribution across cities: US evidence from a QSE model
Authors: Ghinami Francesca
Published: December 2023

This study investigates the impact of remote work adoption on the size and competitiveness of cities in the United States. As a contribution to the ongoing debate sparked by the Covid-19 pandemic, the research initially establishes city-specific upper-bound measures of potential remote work adoption, utilizing the share of employment in remotely-performable occupations for each city. Subsequently, it employs a Quantitative Spatial Economic model, incorporating shipping and commuting costs, to assess the counterfactual effects that these potential levels of remote work adoption would have on population distribution across US cities.Model predictions indicate that upon full remote-work adoption, only select highly productive cities would grow in size and productivity, tothe detriment of the majority of locations. Nevertheless, the emerging spatial equilibrium yields generalized welfare gains characterized by reduced markups in larger cities, extending even to shrinking cities through the pro-competitive effect of trade.The findings suggest a policy-relevant dual role of remote work, concurrently enhancing welfare while reinforcing agglomeration and inequality across cities.
Intercultural Information Ethics Applied To The Data Colonialism Concept.
Authors: Melo Jonas Ferrigolo
Published: December 2023

There is a universalized and socially accepted view of order and totality focused on the processing of personal data, categorizing subjects and configuring criticism in a European view that sustains the dynamics of modernity, giving rise to what is called Data Colonialism. This paper explores the relationship between Data Colonialism and Intercultural Information Ethics - IIE, focusing on whether these concepts are connected. The study argued that just as industrial capitalism transformed society by commodifying labor, data capitalism is changing society by commodifying human life through collecting, controlling, and exploiting personal data. This practice contributes to class division and digital colonialism, where digital territories become sites of extraction and exploitation. Data Colonialism and IIE both address issues of informational justice in diverse cultural contexts. IIE can provide insights into analyzing these relationships from the perspective of local cultures on privacy, informed consent, and information sharing, which differ greatly between different cultures. IIE understand and respect different cultural perspectives on information, while Data Colonialism refers to companies and governments exploiting personal data without consent and reproducing colonial power relations. An intercultural ethical approach to information can help analyze the effects of data colonialism and promote justice and equity in different cultural contexts. By recognizing these colonization processes in the digital age, in which there are ethical implications in relation to the transit of information and cultural differences, we propose to think about this complex network from the Intercultural Ethics of Information.

Published: December 2023

The aim of the study was to assess the potential of spatial modeling of soil humus content through measurements with unmanned aerial vehicle (UAV), using digital relief model combined with geostatistical and regression methods. Location and time of the study. The study area was in the Middle Urals (Perm municipal district of the Perm region) in the southern taiga zone of the Central Russian province. The key area of the surveyed territory is located on the educational and scientific experimental field of the Perm State Agro-Technological University (56°34-37'N and 57°92-93'E). Soil samples were taken with a drill from a depth of 0–20 cm in May 2023. Methods. The survey data was obtained using the drone DJI mini 2 UAVS from a height of 50 m. The orthophotoplan and digital elevation model of the key site were made using the Drone Deploy software. The object of research was the soil cover of the site, represented by sod-podzolic soils. The soil humus content was determined using potassium digestion method. The UAV data processing was performed using the QGIS 3.22 system and SAGA 9 software. Spatial modeling was carried out using the geostatistical method “Ordinary Kriging” employing the Geostatistical Analyst tool of the ArcGIS 10.8 geographic information system. Results. Humus content in in the 0-20 cm soil layer varied from 0.9 to 3.0%, following normal distribution, thus allowing using the normal labels method without data transformation. The U-shape indicated a strong trend direction from north to south and from west to east. The correlation analysis showed the association of humus content with the morphometric parameters, the correlation coefficient ranging from -0.48 to 0.75. A regression equation was constructed for predicting soil humus content by using the parameters with the maximal correlation coefficients such as height (ELEV), distance to watercourses (Channel Network Distance) and relative position of the slopes (Relative Slope Position), having the correlation coefficients of 0.75, 0.75 and 0.66, respectively. This equation was found to model spatial humus with a relative divergence from Kriging interpolation of -0.6…-1.1%. Conclusions. The use of highly detailed UAV images to establish the influence of geomorphological conditions on soil properties allows not only to determine their spatial distribution, establish relationships with surface elevations, distance to watercourses, but also to simulate property changes in properties due to anthropogenic intervention, which, among other things, can enhance water erosion.
Improving MSMEs with digital business-based community empowerment model in Pangandaran region, Indonesia: A system dynamics perspective
Authors: Novita Asti Amelia , Wismanu Rendra Eko , Wahyudi Lestari Eko
Published: December 2023

The creative economy has become Indonesia's new potential after being included in the national development strategic plan. In 2007, creative economy program was started by the Indonesian Agency for Creative Economy and has now merged into the program of Ministry of Tourism and Creative Economy (Kemenparekraf). This study aims to build a digital business-based community empowerment model to improve MSMEs’ resilience in the midst of pandemic. A qualitative approach and system dynamics model were used to investigate the handicraft sector in Pangandaran Regency. This study found that MSMEs in Pangandaran Regency still relied on government support. Also, the handicrafts creation was still below the standard and the quantity was not sufficient. Moreover, the business actors still lacked the capital. This condition was exacerbated by the lack of use of digital marketing by craftsmen. Efforts made by the government were intensive assistance. Although it was still quite far from what was expected, the programs implemented by the relevant agencies were quite significant. Even though the penta-helix synergy has been performed to develop MSMEs in Pangandaran Regency, there were some stakeholders that had not optimally implemented their functions.JEL Classification C26; I26; J15

This study aims to analyze financial literacy affecting export and import decisions, and to analyze what individual and social factors affecting the said financial literacy. The design of this research was clausal associative, with quantitative approach. The sample of this research was MSME actors in Central Java province who were successful or oriented towards carrying out export and import activities. The data collection techniques were questionnaires and documentation. This study used structural equation modeling with Lisrel 8.80 software. The data were analyzed with Confirmatory Factor Analysis. The results showed that there was a significant effect between individual ability on financial literacy and financial literacy on export and import decisions, while between social variables and financial literacy, there was not a significant effect. MSMEs had cooperative characteristics in running their business to complement each other's limitations and gain specific competitive advantages to compete in the global environment, especially export and import activities, so that they could contribute to the national economy. Suggestions for further research, the government should act as an aggregator or facilitator for sharing knowledge regarding financial literacy between MSMEs, MSMEs and academics, MSMEs and related communities, and MSMEs and national private parties.JEL Classification F20; G53; L26

Published: December 2023

Rice farming is a business that has many risks, and production risks cause fluctuations in production. Productivity influences farming income and profitability. An increase and decrease in production will affect revenue or profitability. The purpose of this study is to analyze the technical efficiency, production risk, and profitability of rainfed lowland rice farming. This research was conducted in two regencies in South Sulawesi Province, namely Maros Regency and Pangkajene Islands Regency. The sample of this study was 100 farmers in rainfed rice fields. This research used quantitative methods with a survey approach. Data were collected using observation, recording, and interview instruments, and were then analyzed using quantitative description coupled with a t-test for independent samples. The results showed that rainfed lowland rice farming in Maros Regency and Pangkajene and Archipelago Regency was technically efficient. Rainfed lowland rice farming in Maros Regency and Pangkajene Regency and Islands is at risk.  Rainfed lowland rice farming in Maros Regency and Pangkajene Regency and the islands using profitability analysis generates income and profit, and is feasible to cultivate. Farmers need to use production inputs as recommended to increase production reduce production risk and efficiently use inputs.JEL Classification D10; Q00; Q12
The Influence of economic growth, exchange rate, and inflation on foreign tourist visits to Indonesia
Authors: Rifai Nila , Kurniawan Taufiq
Published: December 2023

Tourism is one of the economic sectors that can quickly bring in foreign exchange for the country if managed properly and sustainably. Many economic variable factors influence the demand and supply of the tourism industry, especially the level of foreign tourist visits, such as economic growth, exchange rate, and inflation. This study aimed to determine the influence of economic variable factors, especially economic growth, exchange rate, and inflation, on the number of foreign tourist visits in Indonesia. A quantitative descriptive method is used in this study. To analyze the factors influencing the number of foreign tourist visits in Indonesia, independent variables such as economic growth, exchange rate, and inflation are used in the Multiple Linear Regression equation model. The data used in this study is secondary data on annual time series for the period 2001 – 2020. The research result shows that the number of foreign tourist visits in Indonesia is significantly influenced by economic growth and the exchange rate, while inflation has no significant effect. There are still other factors (non-economic) that influence the decision of tourists to visit. Several factors that need to be considered to increase the interest of foreign tourists visits in Indonesia are tourist attractions, accessibility, amenities, ancillary, attractive promotions, and social, political, and security stabilityJEL Classification A13; B55; D69

Autobiographical tendencies in Boris Ryzhy’s works. The Rotterdam Diary [Rotterdamskiy dnevnik]
Authors: Vashchuk V. E.
Published: December 2023

The article analyzes the autobiographical features of The Rotterdam Diary [Rotterdamskiy dnevnik], the only prose work by the late poet B. Ryzhy, a native of Yekaterinburg. The Diary was written soon after his trip to the Poetry International Festival in the Netherlands in 2000 and can be viewed as the young poet’s confessions that shed light on the logic of his life and work. The book remained unfinished at the time of Ryzhy’s death — his widow and father came up with the title and initiated a posthumous publication in the Znamya journal. The book’s unique quality lies in its tentative genre attribution as well as significant fragmentation of the narrative. Using narratological methods, the article demonstrates the narrator’s use of a nonlinear narrative to put together his own image — that of a loner, a ‘loser,’ and, at the same time, ‘an ordinary Russian poet.’ Interestingly, this image is partially reflected in the poet’s contemporaries also portrayed in the Diary and helps to form an opinion about the lyrical hero from the viewpoint of his typological traits.
The Russian theme in world literature: A co-authored monograph
Authors: Lutsenko E. M.
Published: December 2023

The review offers a detailed analysis of a new co-authored monograph devoted to world literature with a broad focus on the global community’s perception of the Russian theme, including the Russians’ national identity, the nation’s political and social structure, and traditions and customs. Exploring Russia’s active interaction with the West and the East, the author stresses the ‘unity of the diverse.’ The book discusses world literature in the articles devoted to writers from Western, Central, and Eastern Europe, South Korea, China, and Brazil. As the study is confined to the Russian theme, the book encounters limitations: not each interaction between Russia and another nation generated a sense of reciprocity (in Veselovsky’s words, a ‘countercurrent’). Even though the monograph’s geographical scope extends from Brazil to South Korea, two topics stand out: interactions with Germany, and interactions with France. Thoroughly explored by Russian comparativists, they constitute a solid foundation for the presented study.

The review also challenges the theoretical conclusions detailed in the foreword.
Material metaphors in Shalamov’s and Mandelstam’s poetic consciousness
Authors: Krotova D. V.
Published: December 2023

The tradition of Acmeism, among others, was a defining aspect of V. Shalamov’s artistic origins. The article examines Shalamov’s artistic interaction with the prominent Acmeist poet O. Mandelstam, demonstrates the key trends in the interpretation of material imagery traceable in the poets’ works, and discusses their individual artistic approaches to developing this imagery. Mandelstam was famously revered by Shalamov the author: Not only did he produce a portrayal of Mandelstam in the short story ‘Cherry Brandy’ of the Kolyma Tales [Kolymskie rasskazy], but also drafted a speech to be delivered at a 1966 gathering dedicated to Mandelstam’s 75th anniversary (the notes are kept in Shalamov’s archive at RGALI [Russian State Archive of Literature and Art]). In his notes, Shalamov mentions that his artistic affinity with Mandelstam reveals itself in similar attention to the material world, or the world of objects; adherence to Acmeist values; and artistic and personal nonconformism. D. Krotova finds proof of this affinity in Shalamov’s poetry and prose, citing his published output as well as works preserved at RGALI.

Published: December 2023

Огляд літератури присвячений актуальній проблемі дитячої охорони здоров’я – синдрому "дитина, яка часто хворіє", наведена детальна характеристика категорії "діти, які часто хворіють" на повторні гострі респіраторні захворювання (ГРЗ), збудники, що викликають захворювання дихальних шляхів. Заслуговують на увагу чинники, що спричинюють повторні ГРЗ, включаючи генетично обумовлені причини (порушення стану здоров’я матері), представлена генетична детермінованість повторних і рецидивуючих ГРЗ, пов’язаних з групою крові. Розвиток імунного дисбалансу проявляється у змінах клітинної і гуморальної імунної відповіді, а також в чинниках неспецифічної резистентності, що характеризують зміни місцевого імунітету, який формує розвиток хронічної патології. Описано вплив алергічного компонента на тяжкий перебіг ГРЗ і взаємозв’язок з механізмами розвитку нейроендокринної та імунної систем. Корекцію порушень імунної резистентності дітей, які часто хворіють, проводили циклофероном, що сприяло зниженню захворюваності і тривалості епізодів повторних ГРЗ на рік.

Застосування комбінації метформіну і раміприлу (відповідно 1000 мг і 5 мг на день) у комплексному лікуванні метаболічного синдрому (МС) протягом 6 міс приводить до покращання клінічного перебігу ішемічної хвороби серця (ІХС) – зменшення кількості та тривалості больових серцевих приступів, зниження функціонального класу стенокардії напруги, зменшення проявів хронічної серцевої недостатності, нормалізації артеріального тиску і зменшення абдомінального ожиріння. Це можна розглядати як профілактику розвитку цукрового діабету типу 2 та його серцево-судинних ускладнень. Комбінація метформіну і раміприлу в комплексному лікуванні МС є ефективним і безпечним варіантом терапії цього синдрому.
Исследование динамики изменения показателей эмоционального состояния в ходе учебного процесса у иностранных и отечественных студентов спортивных специальностей
Authors: Ivashchenko S. N.
Published: December 2023

Наведено результати порівняльного аналізу динаміки змін самопочуття іноземних і вітчизняних студентів спортивних спеціальностей, визначені на основі вивчення показників їх емоційного стану на різних етапах навчального процесу. Встановлено, що зменшення значень умовного показника психологічної атмосфери дня як головного індикатора емоційного стану студентів в більшій мірі проявляється серед студентів-іноземців. Причиною цього є хронічне емоційне напруження, зумовлене конфліктом між прагненням студентів до успішного засвоєння навчальних програм та неспроможністю ефективного сприйняття навчального матеріалу через недостатньо повне знання термінів професійно-прикладного значення. Одним із способів вирішення даної проблеми є застосування методики прискореного розширення мовного запасу термінів професійно-прикладного значення у програмі попередньої підготовки студентів-іноземців до навчання у вищих навчальних закладах України.

Published: December 2023

OBJECTIVE

Patients with pulsatile tinnitus (PT) are often referred for digital subtraction angiography (DSA) to exclude cranial dural arteriovenous fistula (DAVF). Because DSA is not without risk, the authors studied the sensitivity and specificity of an automated detection algorithm that analyses external ear canal sound measurements to evaluate the presence of DAVF in PT patients.

METHODS

Between 2015 and 2021, external ear canal sound measurements of 72 PT patients were collected prospectively at our tertiary tinnitus clinic preceding referral of these patients to the neurosurgical department for counseling about DSA. The measurements were analyzed with an algorithm that objectifies a pulsatile sound as a PT coherence index (PTCI) per frequency band.

RESULTS

Ultimately, DSA was performed in 49 PT patients. DAVF was revealed in 15 patients (31%). PTCI cutoff values of 0.7 (at 250 Hz) and 0.6 (at 1000 Hz) resulted in sensitivity of 100% (78%–100%) and specificities of 62% (44%–78%) and 68% (49%–83%), respectively, for detecting DAVF on DSA.

CONCLUSIONS

Analysis of external ear canal sound measurements in PT patients showed 100% sensitivity for detecting DAVF on DSA. This analysis can potentially be used as a screening tool to help clinicians and PT patients to decide on the necessity of DSA. Retrospectively, the use of sound measurement in our cohort would have narrowed the indication for DSA to 23 of 49 cases (47%) without missing a DAVF.

OBJECTIVE

There are few reports of outcomes following stereotactic radiosurgery (SRS) for the management of cerebral cavernous malformations (CCMs) of the basal ganglia or thalamus. Therefore, the authors aimed to clarify these outcomes.

METHODS

Centers participating in the International Radiosurgery Research Foundation were queried for CCM cases managed with SRS from October 2001 to February 2021. The primary outcome of interest was hemorrhage-free survival (HFS) with a secondary outcome of symptomatic adverse radiation events (AREs). Assessment of the association of prognostic factors with HFS was conducted via Kaplan-Meier analysis and log-rank test. Chi-square tests were conducted to assess potential factors associated with the incidence of AREs.

RESULTS

Seventy-three patients were identified. The median patient age was 43.5 years (range 4.4–79.5 years). Fifty-nine (80.8%) patients had hemorrhage prior to SRS. The median treatment volume was 0.9 cm3 (range 0.07–10.1 cm3) with a median margin prescription dose (MPD) of 12 Gy (range 10–20 Gy). One-, 3-, 5-, and 10-year HFS were 93.0%, 89.9%, 89.9%, and 83.0%, respectively, with one hemorrhage-related death approximately 1 year after SRS and nearly 60% and 30% of patients having improvement or stability of symptoms, respectively. There was no correlation between lesion size or MPD and HFS. Seven (9.6%) patients experienced AREs (MPDs > 12 Gy in all cases). Lesion size > 1.0 cm3 was correlated with the incidence of an ARE (p = 0.019). Forty-two (93.3%) of 45 patients treated with an MPD ≤ 12 Gy experienced neither hemorrhage nor AREs following SRS versus 17 (60.7%) of 28 patients treated with an MPD > 12 Gy (p = 0.0006).

CONCLUSIONS

SRS is a reasonable treatment strategy and confers clinical stability or improvement and hemorrhage avoidance in patients harboring CCMs of the basal ganglia or thalamus. An MPD of approximately 12 Gy is recommended for the management of CCM.
Conditioned recurrence-free survival following gross-total resection of nonfunctioning pituitary adenoma: a single-surgeon, single-center retrospective study
Authors: McClure Jesse J. , Chatrath Ajay , Robison Trae R. , Jane John A.
Published: December 2023

OBJECTIVE

The authors sought to determine the time to recurrence after achieving gross-total resection of nonfunctioning pituitary adenoma (NFPA) in adult patients. The authors also sought to determine the rate of recurrence after increasing years of recurrence-free imaging.

METHODS

The authors performed a retrospective chart review of all adult patients who underwent gross-total resection of NFPA between September 2004 and January 2018 by the senior surgeon. The primary outcome of the study was time to recurrence, defined by imaging and/or clinical criteria.

RESULTS

The median follow-up time of the 148 patients who met the inclusion criteria was 91 months; 12 of these patients (8.1%) had recurrence. The median time to recurrence was 80 months. The range of time for these recurrences was 36–156 months. The probabilities of remaining recurrence free at 180 months after gross-total resection of NFPA and 12, 36, 60, 84, or 120 months of recurrence-free imaging were 82%, 84%, 86%, 88%, and 93%, respectively. The year-over-year odds of a recurrence increased linearly by 1.07%. There was no difference in recurrence-free imaging when patients were stratified by Knosp grade or tumor subtype. None of the patients with recurrence underwent repeat resection. When identified, patients were managed either conservatively or with radiosurgery.

CONCLUSIONS

Increased intervals of recurrence-free imaging were not associated with a decrease in risk of recurrence, which suggests that patients require life-long periodic imaging. If followed with periodic imaging, recurrence can be discovered before clinically symptomatic and successfully treated without repeat surgery.
Association between hospital volume and in-hospital mortality in pediatric severe traumatic brain injury: a nationwide retrospective observational study in Japan
Authors: Utsumi Shu , Ohki Shingo , Ueda Takeshi , Amagasa Shunsuke , Nishikimi Mitsuaki , Shime Nobuaki
Published: December 2023

OBJECTIVE

The objective of this study was to investigate the association between hospital volume and in-hospital mortality in pediatric patients with severe traumatic brain injury (TBI).

METHODS

This retrospective cohort study used data from the Japan Trauma Data Bank between 2010 and 2018, specifically those of pediatric patients with severe TBI (Glasgow Coma Scale [GCS] score < 9 and head Abbreviated Injury Scale score > 2). Hospital volume was defined as the number of pediatric patients with severe TBI throughout the study period. Hospital volume was categorized as low (reference category: 1–9 patients), middle (10–17 patients), or high (> 18 patients) volume. Multivariate mixed-effects logistic regression analysis was performed to determine the association between hospital volume categories and in-hospital mortality. Subgroup analyses were performed using data on craniotomy and the presence of severe torso injuries. In the sensitivity analyses, patients with a GCS score of 3, interhospital transfer, and major intensive care unit complications were excluded.

RESULTS

A total of 1148 pediatric patients with severe TBI, with a median age of 12 years (IQR 7–16 years), treated at 141 hospitals were included. In total, 236 patients (20.6%) died in the hospital. Multivariate analysis showed no significant association between hospital volume and in-hospital mortality (high volume: OR 1.15, 95% CI 0.80–1.64; middle volume: OR 0.89, 95% CI 0.62–1.26). Subgroup and sensitivity analyses showed similar results.

CONCLUSIONS

Hospital volume may not be associated with in-hospital mortality in pediatric patients with severe TBI.

OBJECTIVE

Over the past several decades, the number of women applying to medical school has increased significantly. However, parallel recruitment and retention of women in the field of neurosurgery continues to lag. The aim of this study was to identify the ratio and trend of female neurosurgery residents to the total number of residents during the past 7 years across all US neurosurgery residency programs.

METHODS

The authors conducted a cross-sectional demographic study investigating the ratio of female neurosurgery residents to the total number of neurosurgery residents across US neurosurgical programs from 2016 to 2022. Using the Fellowship and Residency Electronic Interactive Database, all neurosurgical residency programs in the US were collected. Data were further divided into postgraduate years 1–7 to dissect the data collection per residency year. One hundred fourteen programs were included in the study.

RESULTS

The number of female neurosurgery residents was 71 (29.8%) in 2022, 58 (25.2%) in 2021, 65 (27.9%) in 2020, 62 (27.3%) in 2019, 46 (21.4%) in 2018, 33 (15.2%) in 2017, and 34 (15.9%) in 2016. The trend line showed a significant increase using the Mann-Kendall test (p = 0.035). The total number of international medical graduate (IMG) female neurosurgery residents was 3 (4.2%) in 2022, 4 (6.9%) in 2021, 3 (4.6%) in 2020, 1 (1.6%) in 2019, 1 (2.2%) in 2018, 1 (3%) in 2017, and 2 (5.9%) in 2016.

CONCLUSIONS

The number of women matching into neurosurgery residency programs is modestly increasing, especially for IMG women. Future steps toward fewer gender disparities should focus on career advancement and leadership diversification in organized and academic neurosurgery.

OBJECTIVE

Patient-perceived functional improvement is a core metric in lumbar surgery for degenerative disease. It is important to identify both modifiable and nonmodifiable risk factors that can be evaluated and possibly optimized prior to elective surgery. This case-control study was designed to study risk factors for not achieving the minimal clinically important difference (MCID) in Patient-Reported Outcomes Measurement Information System Function 4-item Short Form (PROMIS PF) score.

METHODS

The authors queried the Michigan Spine Surgery Improvement Collaborative database to identify patients who underwent elective lumbar surgical procedures with PROMIS PF scores. Cases were divided into two cohorts based on whether patients achieved MCID at 90 days and 1 year after surgery. Patient characteristics and operative details were analyzed as potential risk factors.

RESULTS

The authors captured 10,922 patients for 90-day follow-up and 4453 patients (40.8%) did not reach MCID. At the 1-year follow-up period, 7780 patients were identified and 2941 patients (37.8%) did not achieve MCID. The significant demographic characteristic–adjusted relative risks (RRs) for both groups (RR 90 day, RR 1 year) included the following: symptom duration > 1 year (1.34, 1.41); previous spine surgery (1.25, 1.30); African American descent (1.25, 1.20); chronic opiate use (1.23, 1.25); and less than high school education (1.20, 1.34). Independent ambulatory status (0.83, 0.88) and private insurance (0.91, 0.85) were associated with higher likelihood of reaching MCID at 90 days and 1 year, respectively.

CONCLUSIONS

Several key unique demographic risk factors were identified in this cohort study that precluded optimal postoperative functional outcomes after elective lumbar spine surgery. With this information, appropriate preoperative counseling can be administered to assist in shaping patient expectations.
