Published: June 2024

Ensuring road transport safety is a critical imperative for regional development and public welfare. This abstract outline a comprehensive evaluation framework designed to assess the service level of regional road transport safety. The proposed methodology integrates diverse parameters, encompassing infrastructure, technology, policy, and human factors, to provide a holistic understanding of the safety landscape. Using real-time data integration and powerful analytics, the assessment system combines quantitative and qualitative indicators. Technology aspects of infrastructure evaluations centre on the effectiveness of automated transportation systems and their influence on accident reduction; architecture evaluations also cover the layout of roads, advertising, and maintenance requirements. Policy evaluation is examining current laws and the ways in which they are enforced while considering how they affect the behaviour of drivers and public safety. The proposed method uses DCNN method for intelligent road transport safety. Using DCNN algorithms to monitor and regulate traffic congestion in smart cities represents a significant leap in the use of deep learning in traffic management.

Published: June 2024

The embedded ultra-precision displacement measurement is of great interest in developing high-end equipment as well as precision metrology. However, conventional interferometers only focus on measurement accuracy neglecting the sensor volume and requirement of embedded measurement, thus hindering their broad applications. Here we present a new sensing method for realizing large-range displacement measurement in narrow space scenarios based on the combination of a fiber microprobe interference-sensing model and precision phase-generated carrier. This is achieved by microprobe tilted-axis Gaussian optical field diffraction and high-order carrier demodulation to realize large-range displacement sensing. It is uncovered that the microprobe element misalignment and phase demodulation means play pivotal roles in the interference signal and the accuracy of large-range displacement sensing. The analysis shows that the proposed interference-sensing method can effectively reduce the nonlinearities. Experimental results illustrate that the measurement range extends from 0 to 700 mm. Furthermore, the maximum nonlinear error is reduced from tens of nanometers to 0.82 nm over the full range, allowing subnanometer accuracy for embedded measurements in the hundreds of millimeters range.

Published: June 2024

Background
Pathogens can impact host RNA modification machinery to establish a favorable cellular environment for their replication. In the present study, we investigated the effect of Toxoplasma gondii infection on host RNA modification profiles and explored how these modifications may influence the host-parasite interaction.

Methodology/principal findings
We analyzed the modification levels of ∼ 80 nt tRNA and 17–50 nt sncRNAs in mouse liver, spleen, and serum using liquid chromatography and tandem mass spectrometry analysis. The results revealed alterations in RNA modification profiles, particularly during acute infection. The liver exhibited more differentially abundant RNA modifications than the spleen. RNA modification levels in serum were mostly downregulated during acute infection compared to control mice. Correlations were detected between different RNA modifications in the liver and spleen during infection and between several RNA modifications and many cytokines. Alterations in RNA modifications affected tRNA stability and protein translation.

Conclusions/significance
These findings provide new insight into the role of RNA modifications in mediating the murine host response to T. gondii infection.

Authors: Hosseininejad Seyyed-Mohsen , Emami Meybodi Mohammad Kazem , Raei Mehdi , Rahimnia Alireza 
Published: June 2024

Background
Anterior cruciate ligament (ACL) tear is common in military setting; such an injury increase institutional costs and workforce strain, however, few studies have investigated the mechanism and associated factors of ACL tear specifically in a military setting. The aim of this study was to investigate the prevalence and mechanisms of ACL tears in military personnel at a military referral hospital in Iran.

Material and methods
This cross-sectional study examined 402 military personnel who presented with knee complaints at a single referral Iranian military hospital. The ACL injury prevalence and mechanisms were assessed by physical examination, medical records, and magnetic resonance imaging (MRI) of the knee. Data were collected by an orthopedic resident.

Results
Of the total 402 patients, 285 were diagnosed with ACL tears; the prevalence was 70.9%. The most common mechanism leading to ACL tear was noncontact events. The knee changing direction-knee pivoting (54%) was the most frequent lower limb status, followed by a fall with the knee in valgus position (20.7%). The most commonly associated activity was military training (63.9%) and sports activities (32.6%). The incidence of ACL injuries was higher in soldiers compared with officers during military training, but higher in officers during sports exercises (P = 0.002). Common associated injuries involved the knee meniscus and cartilage.

Conclusion
The findings support those of previous studies, that in military personnel, the most common knee injury is damage to the ACL, most frequently through noncontact events, specifically knee pivoting, during military activities rather than sports and among soldiers. These findings help develop ACL injury prevention programs.

Background
Foster families may represent an alternative model for dependent older adults in many countries where nursing homes are insufficiently developed. This study aimed to assess the prevalence of malnutrition and its determinants in older adults living in foster families in Guadeloupe (French West Indies).

Methods
This cross-sectional study was gathered from the KASAF (Karukera Study of Ageing in Foster families) study (n = 107, 41M/66F, Mdn 81.8 years). Nutritional status was assessed with the Mini Nutritional Assessment Short‐Form (MNA‐SF). Clinical characteristics and scores on geriatric scales (Mini-Mental State Examination (MMSE), Activities of Daily Living (ADL), Short Physical Performance Battery (SPPB), Center for Epidemiologic Studies- Depression (CESD) and Questionnaire Quality of Life Alzheimer’s Disease (QoL-AD)) were extracted. Bivariate analysis and logistic models adjusted for age and gender were performed to test the association of nutritional status with socio-demographic variables and geriatric scales.

Results
Thirty (28.0%) older adults were malnourished (MNA-SF score ≤7). In bivariate analysis, malnutrition was associated with an increased prevalence of cardiovascular diseases (46.7% versus 19.5%, p = 0.004), the presence of hemiplegia (30.0% versus 6.5%, p = 0.003), a poorer cognitive status (MMSE score 4.7 ± 7.1versus 9.7 ± 10.7; p = 0.031), higher risk of depression (CESD score 27.3 ± 23.0 versus 13.5 ± 14.4; p = 0.035) and dependency (ADL score 1.9 ± 1.9 versus 2.3 ± 2.1; p<0.001). Malnutrition was also associated with lower caregivers’rating of QoL (QoL-AD score 21.8 ± 6.4 versus 26.0 ± 5.7; p = 0.001) but not by older adult’s rating (24.1 ± 11.2 versus 28.3 ± 7.7; p = 0.156). Similar associations were observed in logistic models adjusted for age and gender.

Conclusion
Malnutrition was common among foster families for older adults. Special attention towards the prevention and treatment of malnutrition in older adults from cardiovascular diseases, cognitive impairment, dependency and depression is necessary in this model of dependency support.
"A-Stoff Anlagen": die Versorgung mit flüssigem Sauerstoff im deutschen Fernraketen Programm 1931-45
Authors: Schmundt-Thomas Georg 
Published: June 2024

Die deutsche A4 war die erste einsatzfähige ballistische Fernrakete, als Treibstoff diente ein Gemisch aus Ethanol und flüssigem Sauerstoff. Flüssiger Sauerstoff hatte den Tarnnamen "A-Stoff" und wurde in eigens errichteten Betriebsstätten im Besitz der Wehrmacht hergestellt. Die Sauerstoffwerke waren unter Einsatz von Zwangsarbeitern und KZ-Häftlingen gebaut worden und wurden mit ihnen betrieben. Im Zuge der Planung der Serienfertigung und des militärischen Einsatzes stellte sich spätestens im Sommer 1941 heraus, dass die Herstellung und Versorgung mit flüssigem Sauerstoff das Nadelöhr sein würde, von dem die Gesamtzahl der einsetzbaren Raketen abhängen würde. Die vorliegende Studie basiert auf einer umfassenden Sichtung und Auswertung der relevanten Aktenbestände im Bundesarchiv Militärarchiv in Freiburg und beschreibt die Versorgung mit Flüssigsauerstoff im deutschen Raketenprogramm von den Anfängen in der Weimarer Republik bis zur Kapitulation des Dritten Reichs.
The German A4 rocket was the first operational ballistic missile. It was fueled by a mix of ethanol and liquid oxygen. Liquid oxygen was codenamed "A-Stoff." It was produced in dedicated factories run and operated by the German army. The factories had been built by and were operated using forced labor and concentration camp inmates. As early as summer 1941 it became clear that the supply of liquid oxygen would be the bottleneck, limiting the total number of rockets that could be used. The present study is based on a thorough analysis of existing contemporary files today held at the German Bundesarchiv-Militaerarchiv in Freiburg. It describes how liquid oxygen was provided to the German rocket program from its beginnings during the Weimar republic to the collapse of the Third Reich. The text is in German.

ABSTRACT
Crohn's disease (CD) represents a subtype of inflammatory bowel disease and can affect any portion of the gastrointestinal tract, from the mouth to the anus, with the capacity to affect extraintestinal organs. Salpingo-oophoritis is an uncommon manifestation of CD. There is only a limited number of documented case reports. We present the case of a patient with ileocolonic CD and secondary granulomatous salpingo-oophoritis. We emphasize the significance of clinical suspicion and an interdisciplinary approach as crucial factors in ensuring the effective management of the case.

Objective: to investigate the efficacy and safety of olokizumab (OKZ) in patients with knee osteoarthritis (OA) with synovitis, persistent pain and ineffectiveness of previous conservative therapy. Material and methods. The study included 15 patients with stage II–III knee OA who fulfilled the ACR criteria and had pain ≥50 mm on a visual analogue scale (VAS), synovitis and treatment failure. The age of patients ranged from 54 to 75 years; the duration of the disease was from 1 to 23 years. The duration of the study was 12 weeks, during which the patients received 3 subcutaneous injections of OKZ at a dose of 64 mg. The effectiveness of the treatment was assessed by the dynamics of pain intensity according to VAS, WOMAC and KOOS indices, the values of the DN4 questionnaire and the quality of life according to EQ-5D. In addition, the general assessment of the patient's health (GHA) according to VAS, the assessment of treatment efficacy by doctor and patient and the need for non-steroidal anti-inflammatory drugs (NSAIDs) were considered. All patients underwent laboratory testing. Results and discussion. During treatment, there was a significant decrease in pain intensity according to VAS, a statistically significant improvement in the KOOS and WOMAC indices (p<0.05), quality of life according to the EQ-5D questionnaire and GHA. Patients and doctors rated the treatment results very positively: an improvement or significant improvement was observed in 92.3% of cases. Adverse events were identified in 4 patients, which in 2 cases served as the reason for discontinuation of OKZ treatment and termination of participation in the study. During treatment with OKZ, a statistically significant decrease in CRP and ESR values, an increase in the concentration of interleukin 6 (p = 0.003), COMP (p = 0.03) and PIINP (p = 0.01) were observed. Conclusion. The results obtained suggest a significant symptomatic and anti-inflammatory effect of OKZ in patients with the inflammatory phenotype of OA.

AbstractPulmonary fibrosis is an interstitial scarring disease of the lung characterized by poor prognosis and limited treatment options. Tissue transglutaminase 2 (TG2) is believed to promote lung fibrosis by crosslinking extracellular matrix components and activating latent TGFβ. This study assessed physiologic pulmonary function and metabolic alterations in the mouse bleomycin model with TG2 genetic deletion. TG2‐deficient mice demonstrated attenuated the fibrosis and preservation of lung function, with significant reduction in elastance and increases in compliance and inspiratory capacity compared to control mice treated with bleomycin. Bleomycin induced metabolic changes in the mouse lung that were consistent with increased aerobic glycolysis, including increased expression of lactate dehydrogenase A and increased production of lactate, as well as increased glutamine, glutamate, and aspartate. TG2‐deficient mice treated with bleomycin exhibited similar metabolic changes but with reduced magnitude. Our results demonstrate that TG2 is required for a typical fibrosis response to injury. In the absence of TG2, the fibrotic response is biochemically similar to wild‐type, but lesions are smaller and lung function is preserved. We also show for the first time that profibrotic pathways of tissue stiffening and metabolic reprogramming are interconnected, and that metabolic disruptions in fibrosis go beyond glycolysis.

Published: June 2024

Abstract

Objectives
Due to increasing workload and rising expectations for both undergraduate and speciality training in medicine, teaching in a clinical environment can be challenging. The “Train the Trainer” course, developed by CAL (Chirurgische Arbeitsgemeinschaft Lehre, Deutsche Gesellschaft für Chirurgie (DGCH)), aims to assist clinical teachers in their task. This study investigates the effect the course has on participants’ self-efficacy and teaching motivation.

Methods
Prior to attending the course, participants anonymously completed a 50-question pre-course questionnaire using standardised questions to gather information on biographical data teaching experience, and validated tools measuring teaching motivation and self-efficacy (PRE). Directly after completing the course, participants evaluated it using a 25-question post-course questionnaire (POST1). At least 12 months after the course, participants received a follow-up questionnaire (POST2) by mail. This 44-question form aimed to gather biographical data, review the teaching methods participants had used since their training, and reassess their teaching motivation and self-efficacy.

Results
Between June 2016 and October 2019, 20 TTT courses were held across six German medical faculties. Data were gathered from 241 participants. After the course, 182 POST2 questionnaires were mailed, 61 of which were returned (equals a 39 % return rate). The findings revealed significant increases in teacher self-efficacy (p=0.0025), identified regulation (p=0.0000), and career motivation (p=0.0044). In contrast, there was a significant decrease in introjected regulation (p=0.0048). When comparing the participants to a reference sample selected from literature, significant differences emerged in intrinsic motivation (p=0.0000) and amotivation (p=0.0025).

Conclusions
Course participants already showed strong intrinsic motivation and self-efficacy before taking the course. After completing it, their confidence to meet specific teaching demands based on their abilities had increased. Notably, changes in motivational dimensions identified and introjected regulation point towards a shift in motivational sources, indicating a more self-regulated approach towards participants’ teaching activities. Further research is needed to determine how much of this change was due to course participation.

Abstract
The bleeding time and amount in the short-segment group were shorter than in the long-segment group, and the bleeding volume was less than in the long-segment group. The Japanese Orthopaedic Association low back pain score, Oswestry Dysfunction Index, and lumbar spine stiffness disability index score of the two groups were significantly improved preoperatively, postoperatively, and at 6 months, 1 year, and 2 years post-operation. The differences were statistically significant at different time points within the groups. Neurological function improved to varying degrees postoperatively. The Cobb angle was significantly higher in both groups (P < 0.05). Adjacent vertebral disease occurred in 10 of 64 patients with short-segment fixation, with a prevalence of 15.6%. Preoperative pelvic tilt angle, preoperative pelvic projection angle (PPA), preoperative degree of matching of PPA to LL (PI-LL), and preoperative coronal Cobb angle were higher in patients with adjacent vertebral disease. There were varying degrees of improvement in low back pain and spinal function after short-segment decompression and fusion internal fixation. However, the patients are generally elderly and at risk of persistent low back pain and accelerated degeneration of adjacent segments.
