Abstract

Background
Chronic subdural hematoma (CSH) is a persistent challenge for neurosurgeons, with current relapse, mortality, and morbidity rates not meeting desired outcomes. This study aims to identify the anatomical regions of postoperative residual hemorrhage and discuss their potential implications for surgical practice.

Methods
This retrospective, observational study reviewed the demographic, clinical, functional, and radiographic outcomes of 74 patients who underwent surgery for CSH between January 1, 2017, and October 1, 2021, at a single-center. Data were collected from the hospital's electronic database, including patient history, physical examination records, and preoperative and postoperative imaging.

Results
Postoperative day 1 computed tomography scans revealed the most common region for residual hemorrhage was the inferior frontal gyrus in 17 cases (23.0%; valid percentage: 42.5%). Residual hemorrhage was detected in the superior parietal lobe in 9 cases (12.2%; valid percentage: 22.5%). High valid percentages of residual hemorrhage were also noted in the temporal (62.5%) and occipital (66.6%) regions.

Conclusions
The inferior frontal gyrus, temporal, and occipital regions are the most common sites for postoperative residual hemorrhage in CSH patients. Identifying these regions can guide surgical planning and intraoperative focus, potentially improving patient outcomes. This study provides valuable insights for refining presurgical strategies and targeting specific anatomical areas during surgery.

Authors: Ertilav Esra , Aydin Osman Nuri 
Published: February 2025

Abstract

Aim
The aim of the study was to compare the efficacy of single or double lead in percutaneous spinal cord stimulation (SCS).

Method
Follow-up data of 41 patients (20 patients with double lead, 21 patients with single lead) who underwent percutaneous SCS were analysed. Demographic and clinical examination findings (gender, age, pain characteristic, neurological examination, medications used) and visual analogue scale (VAS) scores were recorded. VAS pain scores, clinical and neurological examination and complication findings were recorded at 1st and 12th months at post-procedure follow-up.

Results
Twenty patients had double lead and 21 patients had single lead. Five patients had root avulsion, 1 patient had complex regional pain syndrome, 1 patient had postherpetic neuralgia, 2 patients had phantom pain, 3 patients had ischaemic pain and 29 patients had postlaminectomy syndrome. In 10 patients, leads were placed in the cervical region and in 31 patients in the thoracic region. There was at least 50% reduction in VAS scores in 71.4% (15 patients) with single lead implantation and 65% (13 patients) with double lead implantation (p = 0.7). Infection was significantly higher in patients with double lead than in patients with single lead implantation (p < 0.05). In 1 patient, generator exchange was performed because the generator was exposed due to skin necrosis. No major complication was recorded.

Conclusion
SCS with single and double lead is an effective method in chronic pain syndromes. SCS with single lead can be preferred in terms of time, cost and labour saving.

Abstract

Introduction
Unicompartmental knee arthroplasty (UKA) is one of the treatment options for patients whose osteoarthritis involves one out of the 3 compartments. Patients who underwent UKA benefited from shorter hospital stays, better range of motion, and lower risk of postoperative complications compared with patients who underwent total knee arthroplasty (TKA). Hydrotherapy is being introduced complementary to conventional postoperative rehabilitation programs. No report on the use of hydrotherapy evaluating physical functions on patients who underwent UKA leads us to carry out the present study. This is a feasibility study to investigate the effects of hydrotherapy on physical functions in patients after primary unilateral UKA.

Methods
A retrospective cohort study recruited 68 patients who underwent primary unilateral UKA. Nineteen patients were allocated to the hydrotherapy group and 49 patients were in the convention group. Patients in the hydrotherapy group received hydrotherapy and conventional physiotherapy, and the convention group was given conventional physiotherapy only. The primary outcome was Knee Society Function Score (KFS) measured before surgery, six months, and one year after UKA. Self-reported walking tolerance, Timed Up and Go Test (TUGT), and 30-s Chair Stand Test (30CST) were conducted before and after the completion of rehabilitation. Pain and range of motion were also covered.

Results
Hydrotherapy group showed significantly higher KFS at 6 months (P = 0.038) and one year (P = 0.030) after operation. Range of motion flexion and extension in the hydrotherapy group were significantly improved at postoperative 4 weeks and the last session of rehabilitation. Self-reported walking tolerance in the hydrotherapy group was significantly longer at the last session (P = 0.011). No significant difference was found in TUGT, 30CST, and pain between the two groups after rehabilitation. In both groups, all outcomes were significantly better as compared to preoperative findings.

Conclusion
Patients who underwent UKA after hydrotherapy complementary to conventional physiotherapy showed significant improvements in functions, range of motion, and time to tolerating walking before rest. Pain, mobility, balance, leg strength, and endurance were comparable between the two groups. Combination of hydrotherapy with conventional postoperative physiotherapy rehabilitation yielded even better outcomes than conventional physiotherapy alone. Further research with advanced study design, larger sample size and longer follow-up periods for patients who underwent UKA is recommended.

Retained Continuous Glucose Monitor Sensor Wire Fragments Presenting as a Swollen Nodule of the Thigh
Authors: Deng Lily , Galganski Laura , Krishnamurthy Mansa 
Published: February 2025

Abstract
A 2-year-old male with genetic-negative, diazoxide-responsive hyperinsulinism presented with a knot in his left, lateral thigh. His hypoglycemia was managed with diazoxide, chlorothiazide, and monitoring via a Dexcom G6 continuous glucose monitor (CGM). X-ray showed 3 metallic wire foreign bodies, consistent with retained Dexcom sensor wires. He was referred to surgery for foreign body removal. Intraoperative fluoroscopy revealed 4 pieces of wire. Two superficial pieces were removed, but 2 small pieces deep to the fascia remained because of significant risk of injury or bleeding if removal was attempted. We present this case to increase awareness in the literature regarding retention of CGM wires. Raised nodules at sites of CGM insertion without fluctuation or erythema and persistent pain should raise suspicion for retention of sensor wires.
Developing a Novel Artificial Intelligence Framework to Measure the Balance of Clinical Versus Nonclinical Influences on Posthepatectomy Length of Stay

Published: February 2025

Abstract

Background
Length of stay (LOS) is a key indicator of posthepatectomy care quality. While clinical factors influencing LOS are identified, the balance between clinical and nonclinical influences remains unquantified. We developed an artificial intelligence (AI) framework to quantify clinical influences on LOS and infer the impact of hard-to-measure nonclinical factors.

Methods
Patients from the 2017 to 2021 ACS NSQIP Hepatectomy-Targeted database were stratified into major and minor hepatectomy groups. A three-tiered model—multivariable linear regression (MLR), random forest (RF), and extreme gradient boosting (XGBoost)—was developed to evaluate the effect of 52 clinical variables on LOS. Models were fine-tuned to maximize clinical variables’ explanatory power, with residual unexplained variability attributed to nonclinical factors. Model performance was measured using R
2 and mean absolute error (MAE).

Results
A total of 21,039 patients (mean age: 60 years; 51% male) were included: 70% underwent minor resection (mean LOS: 5.0 days), and 30% underwent major resection (mean LOS: 6.9 days). Random forest had the best performance, explaining 75% of LOS variability for both groups (R
2: 0.75). The significant improvement in R
2 from MLR to RF suggests significant nonlinear interactions of clinical factors’ impact on LOS. Mean absolute errors were 1.15 and 1.38 days for minor and major resections, indicating that clinical factors could not explain 1.15 to 1.38 days of LOS.

Conclusions
This study is the first to measure the true influence of clinical factors on posthepatectomy LOS, showing that they explain 75% of the variability. Furthermore, it indirectly evaluated the overall impact of hard-to-measure nonclinical factors, revealing that they account for 25% of LOS.
Το Θέατρο-Ντοκουμέντο ως μέσο καλλιέργειας και ενίσχυσης της "ιδιότητας του πολίτη" σε ενήλικες μαθητές του Σχολείου 18 Άνω (Πρόγραμμα Απεξάρτησης)

Το άρθρο αναφέρεται σε έρευνα δράσης που πραγματοποιήθηκε στο Σχολείο του 18 Άνω για να διερευνήσει την επίδραση του Θεάτρου-Ντοκουμέντο ως μέσου για την καλλιέργεια της «ιδιότητας του πολίτη» των ενήλικων μαθητών του σχολείου. Για τον σκοπό αυτό, σχεδιάστηκε ένα πρόγραμμα δώδεκα παρεμβάσεων που βασίστηκε σε τεχνικές του Θεάτρου Ντοκουμέντο και του Εκπαιδευτικού Δράματος και εφαρμόστηκε σε 11 μαθητές του σχολείου κατά το σχολικό έτος 2022-2023. Ακολουθήθηκε μεικτή ερευνητική προσέγγιση, με στόχο τη σφαιρικότερη προσέγγιση των ερευνητικών ερωτημάτων. Η ανάλυση των ποσοτικών δεδομένων έδωσε ενδείξεις βελτίωσης της «ιδιότητας του πολίτη» της πειραματικής ομάδας, δεν κατέδειξε όμως στατιστικά σημαντικές διαφοροποιήσεις πριν και μετά τις παρεμβάσεις. Αντίθετα, η ανάλυση των ποιοτικών δεδομένων υπέδειξε βελτίωση των «πολιτειακών» δεξιοτήτων (συνεργασία, κριτική ανάλυση), των στάσεων (συμμετοχής και προς τη διαφορετικότητα), αλλά και του ενδιαφέροντος και της προσωπικής συμμετοχής, και μάλιστα η βελτίωση αυτή σχετίζεται με τις τεχνικές του Θεάτρου Ντοκουμέντο.
Ecocultural Perspectives On Mental Well-being and Self-harmony Among Sports Science Students
Authors: Song Peng , Wang Shaojie , Jiang Bo , Zhao Lunan 
Published: February 2025

Drawing on Rogers' humanistic psychology framework, this study explores the interplay between self-harmony and mental health among sports majors. For college students majoring in physical education, this theory serves as a significant reference for maintaining their mental well-being. This research delves into the relationship between the mental health status and self - harmony of physical education majors. By doing so, it aims to offer novel perspectives for the psychological health education and counseling tailored to this specific group of students. A random sampling approach was adopted to recruit physical education majors. Participants completed two validated instruments: the Symptom Checklist 90 (SCL-90) for assessing mental health symptoms, and the Self-Harmony Scale (SCL-HA) to measure congruence between self-concept and experiences. Data collection followed a double-blind protocol to minimize bias. The findings indicate that the disharmony between self and experience has the most profound impact on the mental health of these students, closely followed by communication - related issues. There exists a notable negative correlation between the mental health of physical education majors and the self - experience disharmony, while a significant positive correlation is observed between mental health and self - flexibility. Students with better mental health conditions exhibit remarkably higher levels of self - harmony and self - flexibility compared to those with poorer mental health. Drawing on Rogers' humanistic psychology framework, this study explores the interplay between self-harmony and mental health among sports majors. By employing mixed-method analyses (SCL-90 and SCL-HA scales), we identify key predictors of psychological well-being and propose actionable strategies for enhancing mental health interventions tailored to this cohort.

Published: February 2025

HighlightsLightning strikes vary spatially and temporally. The largest broiler-producing county in both MS and AL have high frequencies of lightning strikes.There is an increase in lightning strikes in MS and AL between the hours of 1600 and 0400 (4 p.m. CST and 4 a.m. CST) when growers and companies are least prepared.More than 50% of annual lightning strikes occur during the summer (June, July, August) months for MS and AL.Abstract. Modern broiler houses are expensive to build, maintain, and insure. Protecting them from extreme weather events is a major concern to producers, integrators, and insurance companies. Lightning strikes can cause catastrophic fires and electrical damage and can lead to costly bird losses, and, therefore, a greater understanding of the impact of lightning on broiler-producing states is needed. The objectives of this study were to (1) perform a long-term evaluation of lightning strike data around heavy broiler-producing areas in Mississippi (MS) and Alabama (AL), (2) spatially map lightning strike densities throughout MS and AL to evaluate spatial and temporal patterns, and (3) observe strike patterns within a 1-mile radius of select broiler farms. Cloud-to-ground lightning strike data for MS and AL for the years 2011-2020 was purchased from a lightning detection service provider and used for analysis. Overall, Mississippi experienced 7% more lightning strikes than Alabama over the 10-year period. Lightning strikes were elevated near coastal regions of both states; however, the highest broiler-producing county in each state had high lightning strike densities. Summer months (June, July, August) experienced the highest number of lightning strikes across both states. There were also increased lightning strikes between 1600–0400 CST for both states. The increased lightning strikes during the hottest months of the year and during nighttime hours mean that producers in both states should ensure that sensitive equipment is properly grounded to protect from lightning damage and that all emergency and alert systems are functioning properly to protect employees and birds and reduce risk from extreme weather events. Keywords: Broiler production, Lightning density, Lightning strikes.
Dissolved oxygen sensing characteristics in blood by hydrogel optical fiber
Authors: Fan Jianglin , Bian Zhenglan , Chu Fenghong , Zhu Wu , Zhou Bin 
Published: February 2025

In this paper, a hydrogel fiber optic sensing probe with a fluorescence indicator doped
in the core is proposed for dissolved oxygen detection in blood. The
hydrogel fiber was made by photocrosslinking with a core-cladding
structure made from PEGDA precursor solutions with different
concentrations. By changing the concentration of the fluorescent
indicator doped in the core of the hydrogel optical fiber and changing
the length of the fiber and the thickness of the cladding, the sensing
performance of the fiber for dissolved oxygen was optimized, and it
was found that the effect of photobleaching could be reduced
appropriately by lowering the excitation power. The resolution is
0.008 ml/dl, with a linearity of 0.99, and the range is
0–2.015 ml/dl, which makes it suitable for the measurement of
the partial pressure of blood oxygen in human beings. The system also
shows good stability and repeatability. Due to the flexibility and
biocompatibility properties, the hydrogel optical fiber dissolved
oxygen sensing probe has promising application in the biomedical
field.
Resolution metric for imaging systems
Authors: Smith Brad C. , Gatt Phil 
Published: February 2025

The resolution of an imaging system is an important metric for quantifying its optical performance. Commonly used metrics like the instantaneous field of view and the Rayleigh criterion have multiple drawbacks, e.g., they ignore aberrations and obscurations, assume spatially uniform detector response, and treat detector and optical resolutions separately. Here, we present a new metric, Ωres, based on the point response function of an imaging system and demonstrate its advantages. We also relate this new metric to the matched filter signal-to-noise ratio and define a generalized two-dimensional sampling Q number.
Global burden of cardiovascular diseases attributable to diet low in seafood omega-3 fatty acids from 1990~2021 and forecasting the future trends: A population-based study
Authors: Mao Qingsong , Tian Xinling , Wang Xingyi , Xu Haitao , Zhang Yunyi , Kong Yuzhe 
Published: February 2025

Background
This research investigates the worldwide influence of cardiovascular diseases (CVD) associated with low intake of seafood omega-3 fatty acids, based on data from the 2021 Global Burden of Disease Study.

Method
The study evaluated the effects of insufficient seafood omega-3 fatty acid consumption on CVD at international, regional, and country levels. It analyzed variations across different demographics, including age and gender, and explored the relationship between disease burden and the Socio-Demographic Index (SDI). Additionally, it utilized an ARIMA model to predict the incidence of CVD connected to this dietary deficiency until 2050.

Result
In 2021, diets deficient in seafood omega-3 fatty acids contributed to roughly 737.88 thousand deaths and 17.87 million disability-adjusted life years (DALYs) from CVD, with a noted decrease in this health impact over the period studied. The most substantial effects were seen in the elderly, particularly those aged 75 and above, with males experiencing a higher disease impact. Future forecasts suggest probable declines in disease rates across all SDI areas. However, nations in North Africa and the Middle East are projected to encounter growing difficulties related to CVD stemming from low seafood omega-3 intake by 2030 and 2050.

Conclusion
These results highlight the critical need for preventive strategies against CVD and stress the significance of dietary management.
From anxiety to coping: Understanding psychological distance and coping skills for climate change and COVID-19 in 10–12-year-old children
Authors: Schuitema Geertje , Lacchia Anthea 
Published: February 2025

Children worldwide experience climate anxiety, defined as a chronic fear of environmental catastrophe. Following other scholars who sought comparison between the perceived risks and our collective responses with the COVID-19 pandemic, as they can both be considered global crises. Children’s emotional responses, psychological distance and coping strategies to climate change compared and COVID-19 are compared, using a mixed-method longitudinal study among 231 primary school children across the Republic of Ireland. Pre-pandemic and post-lock down data were collected measuring children's emotions through surveys using Likert scales and sketches. Sketching, increasingly recognised as a method for assessing emotional expression, is especially useful when language skills are limited. Results suggest that because climate change was more psychologically distant than COVID-19, it was more difficult for children to effectively use emotional-, meaning-, problem-, and relationship-focused coping strategies to deal with their climate anxiety. One important conclusion of this study is that messages and strategies used to motivate adults to take climate action may increase climate anxiety among young children. Also, relationship-focused coping strategies are underutilised to help children deal with climate anxiety, whilst these were promising coping mechanisms during the COVID-19 pandemic. Therefore, creating positive social support and collective action may help young children to cope with climate anxiety.
Language assessment in primary progressive aphasia: Which components should be tested?
Authors: Silva Andressa Aguiar da , Silagi Marcela Lima , Ortiz Karin Zazo 
Published: February 2025

Introduction
Primary progressive aphasia (PPA) is a dementia syndrome whose onset and course manifests with language deficits. There is a lack of instruments for clinical assessment of language in dementia and further research in the area is needed. Therefore, the objective of the present study was to identify language tasks that can aid the process of clinically diagnosing PPA and to determine those tasks most impaired in this population.

Method
A sample of 87 individuals comprising 2 groups was assessed: a PPA group (PPAG) of 29 PPA patients; and a control group (CG) of 58 healthy subjects matched for age and education. All participants underwent a brief cognitive battery followed by a comprehensive language assessment using the MTL-BR Battery.

Results
A statistically significant performance difference was found between the PPAG and CG on the following tasks: structured interview, oral comprehension of phrases, oral narrative discourse, written comprehension of phrases, written dictation, sentence repetition, semantic verbal fluency, oral naming of nouns and verbs, object manipulation, phonological verbal fluency, body part recognition and left-right orientation, written naming of nouns, oral text comprehension, number dictation, written narrative discourse, written text comprehension and numerical calculations (mental and written).

Conclusion
The results revealed that performance of PPA patients was poorer compared to healthy subjects on various language tasks. The most useful subtests from the MTL-BR battery for aiding clinical diagnosis of PPA were identified, tasks which should be prioritized when assessing this patient group.
