Incidental Findings on MRI Brain Imaging in Pilots from the Canadian White Matter Hyperintensity Study
Authors: Danho Sharef , Saary Joan 
Published: February 2025

BACKGROUND: Incidental neuroanatomical findings are commonly identified during brain MRI completed clinically, for research, or for other purposes, including aircrew screening. Such findings range from benign to pathological and some may be disqualifying for flight duties. We present a series of cases with incidental neuroanatomical findings identified in Royal Canadian Armed Forces (RCAF) aircrew during the Canadian White Matter Hyperintensity research study, and the subsequent aeromedical evaluation undertaken to manage them. Our study group performed 48 brain MRI scans on 42 RCAF pilots and 6 aviation physiology technicians and parajumpers. Participants were men ages 25–70 with a mean age of 39.
CASE SERIES: Incidental neuroanatomical findings were detected in four pilots, with six distinct findings (four vascular abnormalities, one arachnoid cyst, and one nonspecific nodule). All cases were asymptomatic. After evaluation of the findings of each case by a medical consortium, including an aeromedical neurologist, all pilots were cleared for ongoing duties with no restrictions.
DISCUSSION: The rate and nature of incidental findings in RCAF members in the White Matter Hyperintensity Study is consistent with that found in both the general population and in other military pilot populations. There is no international standard for screening or management of incidental findings; therefore, we recommend an approach that involves a case-by-case evaluation of the findings by a multidisciplinary medical team, with careful identification and consideration for high-risk features.

Cochlear Implants in Aviators
Authors: Schall David G. 
Published: February 2025

INTRODUCTION: Cochlear implants (CIs) have revolutionized the management of deafness. Combined with newborn screening, children are being identified earlier and rehabilitated with CIs, allowing them to be mainstreamed in the education system. The aviation community has begun to see a new generation of pilots who are now seeking careers in aviation with the use of CI.
METHODS: A literature review using the Ovid Medline database was conducted. A search for airmen within the Federal Aviation Administration (FAA) Airman Medical Certification System with a diagnostic code for CIs was reviewed up to the year 2021.
RESULTS: There are no studies to date documenting airmen with CIs. The FAA has certified 42 airmen with Cis, including 10 with First Class Medical Certificates. Airmen with CIs have been able to successfully pursue careers in aviation from general aviation to commercial airline pilot in the United States.
DISCUSSION: CIs are used for both bilateral and single-sided deafness and are becoming more prevalent within the general population. Applicants with CIs are now seeking careers in aviation in increasing numbers. The FAA has successfully certified airmen from Class III to Class I airline pilots. It requires appropriate evaluation and screening, including a medical flight test to document adequate communication, recognition of alarms within the cockpit, and the ability to communicate with air traffic control.

Authors: Pelham Andrew , Van Tongeren Martie , Arnold Heidi , Cocco Pierluigi 
Published: February 2025

INTRODUCTION: A study of fatigue in British military rotary-wing pilots was conducted to determine the utility of actigraphy-driven fatigue modeling in the military rotary-wing environment.
METHODS: A total of 48 pilots were recruited across the 3 military services of the United Kingdom. Objective fatigue was predicted using wearable actigraphy and the Sleep Activity Fatigue Task Effectiveness (SAFTE) fatigue model. Subjective data were collected from daily questionnaires completed by the study subjects, including an assessment of their own fatigue level using Samn-Perelli Scale scores. The relationship between these two data sets was then assessed with correlation and linear regression modeling.
RESULTS: There were 38 men and 2 women recruited. The mean age was 36.4 yr (standard deviation ± 6.5, range 26–52 yr). In total, 200 flights were undertaken, with a mean flight time of 156 min (± 77.1, range 15–480); the mean landing time of these flights was 18:45 (range 11:00–02:30). The data included 37 d of pilots deployed on exercise. SAFTE scores were shown to decline for night flying, especially if landing after 22:00. With increasing subjective levels of fatigue, the relationship between SAFTE and Samn-Perelli Scale scores in subjects weakened.
DISCUSSION: Actigraphy-driven modeling has a role in specific aspects of military rotary-wing aviation. Consideration should be given to its use in specific scenarios, including night-flying and flights undertaken when deployed on exercise.

Authors: St-Martin Philippe , Lalonde François , Bouchard-Lévesque Félix , Dionne Isabelle J. 
Published: February 2025

INTRODUCTION: Through the Artemis program, space agencies and astronauts are preparing for extended durations in space and on planetary surfaces, expanding their occupational tasks. Although standardized laboratory tests are effective in assessing health and mitigating deconditioning, their reliability in forecasting occupational performance is uncertain. Consequently, a recent shift in exercise testing has emerged, shifting focus from health-oriented criteria to operational performance. This involves identifying the physical demands associated with components of an astronaut’s tasks and determining a minimum level of performance, referred to as Physical Employment Standards. The aim of this systematic review is to provide an updated overview of the scientific literature on astronaut occupational tasks and physiological requirements.
METHODS: A search was conducted spanning from 1970 to October 2023. Articles meeting the inclusion criteria underwent screening using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for an evidence-based systematic review.
RESULTS: There were 10 studies selected for inclusion in the current review and pertinent information was extracted. There were 14 tasks physiologically assessed: ambulation on various terrains, physical abilities field, device operations/activity board, re-entry and landing, hatch opening, capsule egress, recovery from fall, jump down, ladder climb, material transfer, emergency crewmember drag, hand drilling, construction wrenching, and upper-limb weighted tasks.
DISCUSSION: Physical Employment Standards for astronauts have yet to be established; however, certain tasks have been identified, enabling tailored occupational assessments for astronauts, increasingly recognized as tactical athletes. The results of this literature review lay the foundations for scientific task analysis and the development of operational physical tests for astronauts.

Prevalence and family function associated with suicide-related behaviors in vocational college population of southern China: the mediating role of depression
Authors: Wang He , Zhong Yingyu , Wang Yueyun 
Published: February 2025

BackgroundSuicide is positively associated with a range of psychological risk factors such as family function and depression. However, it remains unclear if depression mediates the association between family function and suicide in Chinese adolescents.MethodsWe enrolled 14263 students from Shenzhen Polytechnic College, China. Family function, depression and suicide were assessed in these students by self-report measures, respectively. With path analysis and logistic regression, the mediating role of depression in the association between family function and suicide was analyzed.ResultsIn this study, the detection rate of suicide-related behaviors among vocational school students was 12.19%, among which the detection rates of suicide idea, suicide plan and suicide attempt were 11.59%, 4.26% and 2.70%, respectively. Depression played a significant mediating role in the influence of family function on suicide-related behaviors.ConclusionsPoor family function might increase the risk of suicide-related behaviors in vocational school students, and this effect was partly realized by affecting their mental health. Improving family function could not only improve adolescent’s psychological status, but also reduce their suicide-related behaviors.

Published: February 2025

BackgroundThe physical activity of the old people is affected by many factors, and the economic situation is an important factor affecting the physical activity. However, the relationship between economic autonomy and physical activity patterns among older adult Chinese has not been fully studied.ObjectiveTo investigate the association between different types of economic autonomy and physical activity patterns among Chinese older adults aged 60 and above.MethodsCross-sectional analysis of 1,961 participants from the 2018 China Health and Retirement Longitudinal Study (CHARLS). Economic autonomy was categorized into autonomous and non-autonomous groups. Physical activity was assessed through type, frequency, duration, and purpose, using validated questionnaires.ResultsEconomic autonomy showed positive associations with low and moderate-intensity physical activities (p &lt; 0.05). However, economically non-autonomous individuals demonstrated higher participation in high-intensity physical activities, primarily due to work-related demands (78.7%). The frequency of physical activity was significantly different among economic autonomy groups (p &lt; 0.01).

Authors: Martin Danielle A. , Hook Jane , Kim Sunny Wonsun , Larkey Linda , Lee Rebecca E. 
Published: February 2025

BackgroundIn the U.S., Black adults do not achieve the same life expectancy as their White counterparts, and this is attributable in large part to the development of cardiovascular disease (CVD). Mind–body therapy (MBT) interventions demonstrate improvements in cardiometabolic risk (CMR) factors that promote CVD, with increased feasibility and acceptability in the general population. Less known is the feasibility, acceptability, and evidence of reduction in CMR factors in the U.S. Black population with MBT.PurposeThis study aimed to synthesize the current state of research regarding MBT on CMR factors in middle-aged U.S. Black adults and identify gaps in the literature. Research Question 1: What types of studies have been conducted (study design, theoretical framework, and cultural relevance)? and Research Question 2: What is the feasibility and acceptability and effectiveness of MBT in Black adults for CMR reduction?MethodsFollowing PRISMA-ScR guidelines, a review of three databases was conducted. Our inclusion criteria were articles that (1) describe empirical research; (2) assessed a MBT intervention in middle-aged (35–64) adults with a minimum of 60% Black adult participants for CMR reduction; and (3) written in English. Independent reviewers selected articles for inclusion and data extraction, with a third reviewer providing consensus.ResultsFourteen articles met the eligibility criteria (n = 14). Characteristics included randomized controlled trials (8, 57.1%); single-arm (3, 21.0%); mixed methods (3, 21.0%); sample size (17–375); mean age range 43–64; female (6, 42.8%); theoretical framework (4, 28.6%); culturally adapted (7, 50.0%); and studies demonstrating feasibility and/or acceptability (7, 50.0%). Of the seven articles assessing CMR physiologic factors, five studies observed significant improvement. For the 11 studies assessing CMR psychological factors, 6 studies had statistically significant results and 3 studies identified trends toward positive statistical outcomes.ImplicationA growing body of literature across research stages demonstrating acceptability, and feasibility, and evidence of effectiveness for selected outcomes of MBT in middle-aged Black adults with CMR factors shows promise. Future research recommendations include greater recruitment of Black men for MBT studies, larger sample sizes, and utilizing culturally adapted interventions for engaging Black adults in MBT for reduced CMR factors.
Impacts of organizational support on rice farmers’ adoption of green production technologies—implications for food security and environmental sustainability
Authors: Zhang Xu , Zhang Yuhan , Liu Yang , Ye Feng , Liao Wenmei 
Published: February 2025

IntroductionThe relentless focus on maximizing production has exacerbated ecological challenges, including agricultural surface pollution, soil crusting, and farmland degradation, which increasingly threaten sustainable development. Agricultural green production technologies are essential for balancing food security with environmental sustainability.MethodsThis study examines the role of organizational support in fostering farmers’ adoption of agricultural green production technologies, using survey data from 1,426 rice farmers in Jiangxi Province, China. Ordered logit and moderated mediation models reveal a robust positive effect of organizational support on agricultural green production technology adoption, even after addressing endogeneity concerns.Results and discussionThe findings highlight that the effect of organizational support is more pronounced among farmers with agricultural insurance and those primarily engaged in farming. Mechanistic analysis shows that operation scale partially mediates the relationship between organizational support and agricultural green production technology adoption, accounting for 7.76% of the total effect. Furthermore, social capital acts as a positive moderator, amplifying the impact of organizational support on the operation scale and, subsequently, on agricultural green production technology adoption. These results underscore the need to enhance organizational support measures, promote moderate-scale farming, and cultivate social capital as critical strategies for advancing green agricultural practices.

Published: February 2025

Tepung umbi kimpul (Xanthosoma sagittifolium) mengandung serat pangan tinggi dan berpotensi menjadi substitusi tepung terigu dalam pembuatan roti tawar. Roti sourdough difermentasi secara alami tanpa tambahan starter. Penelitian ini bertujuan untuk mengetahui sifat fisiko-kimia dan organoleptik dari roti tawar sourdough tersubstitusi tepung umbi kimpul dengan perbedaan formulasi. Penelitian dilakukan menggunakan Rancangan Acak Lengkap (RAL) dengan satu faktor, yaitu perbandingan tepung umbi kimpul: tepung terigu sebesar 0 persen:100 persen, 10 persen:90 persen, 20 persen:80 persen dan 30 persen:70 persen. Parameter yang dianalisis adalah kadar air, kadar abu, kadar protein, kadar lemak, dan karbohidrat, ukuran pori-pori, tekstur, warna, volume pengembangan, angka lempeng total (ALT), dan total kapang serta parameter organoleptik berupa penerimaan sensori atribut rasa, aroma, warna, aftertaste, dan keseluruhan. Hasil penelitian menunjukkan substitusi tepung umbi kimpul dalam roti tawar sourdough memberikan pengaruh nyata pada semua parameter pengujian. Makin tinggi konsentrasi tepung umbi kimpul, warna makin gelap, tekstur makin keras, meningkatkan kadar air, menurunkan kadar protein dan abu, menurunkan ukuran pori dan volume pengembangan. Total kapang dan ALT pada roti sourdough memenuhi kriteria SNI 8371:2018. Roti tawar sourdough dengan substitusi tepung umbi kimpul substitusi hingga 30 persen masih memenuhi kriteria SNI 8371:2018, namun secara penerimaan organoleptik substitusi dilakukan hingga 10 persen.

“Kimpul” tuber flour which is high in dietary fibre has a potential as a substitute for wheat flour in white bread production. Sourdough bread is naturally fermented. This study aimed to determine the physicochemical and organoleptic properties of sourdough bread substituted with “kimpul” tuber flour in different formulations. This research used a completely randomized design (CRD) with one factor. The percentages of “kimpul” tuber flour to wheat flour are 0 percent:100 percent, 10 percent:90 percent, 20 percent:80 percent, and 30 percent:70 percent. Parameters analyzed were chemical properties, including moisture content, ash content, protein content, fat content, and carbohydrate content; Physical parameters were pore sizes, texture, colour, and swelling volume. The hedonic organoleptic parameters were taste, aroma, color, after-taste attributes, and overall acceptability. Higher concentration of “kimpul” tuber flour resulted in darker color, increased hardness and water content, reduced the ash and protein content, decreased the size of pores and organoleptic acceptability. The TPC and mold indicate that the sourdough was at a safe level and met the criteria of SNI 8371:2018. While kimpul tuber flour substitution up to 30% complied with SNI 8371:2018 standards, sourdough bread with up to 10% substitution showed comparable sensory acceptability to the non-substituted version.

Published: February 2025

Sektor pertanian, khususnya tanaman pangan padi, memiliki peranan penting bagi perekonomian Indonesia. Analisis data historis produksi padi atau data runtun waktu produksi padi dapat memberikan gambaran pola produksi dan segmentasi wilayah berdasarkan karakteristik tanaman padi. Penelitian ini menggunakan algoritma DTW dan K-Medoids Clustering untuk melakukan segmentasi provinsi di Indonesia berdasarkan data produksi padi tahun 2013-2021. Hasil penelitian menunjukkan tiga cluster wilayah dengan karakteristik produksi padi yang berbeda. Setiap cluster menunjukkan pola produksi yang berbeda dengan anggota cluster lainnya, yang disebabkan oleh perbedaan jarak DTW dalam mengukur kesamaan pola produksi. Cluster 1 memiliki produksi tertinggi, diikuti oleh Cluster 2 dan Cluster 3, masing-masing terdiri dari 16, 7, dan 11 provinsi. Temuan ini dapat digunakan sebagai dasar pengembangan kebijakan pemerintah sesuai karakteristik masing-masing segmen.

The agricultural sector, particularly rice crops, plays a crucial role in Indonesia’s economy. Analyzing rice production historical data, or rice production time series data, can provide insights into production patterns and regional segmentation based on rice crop characteristics. This study employed the DTW algorithm and K-Medoids Clustering to segment provinces in Indonesia based on rice production data from 2013 to 2021. The results of the study indicated three clusters of regions with distinct rice production characteristics. Some regions exhibited different production patterns from other cluster members, attributed to variations in DTW distances used to measure pattern similarity. Cluster 1 had the highest production, followed by Cluster 2 and Cluster 3, with 16, 7, and 11 provinces respectively. These findings can serve as a basis for government policy development tailored to the characteristics of each segment.
