Vascularized lymph node transfer (VLNT) versus lymphaticovenous anastomosis (LVA) for chronic breast cancer-related lymphedema (BCRL): a retrospective cohort study of effectiveness over time.

Microsurgical reconstruction, including vascularized lymph node transfer (VLNT) and lymphaticovenous anastomosis (LVA), have emerged as promising treatment options for chronic breast cancer-related lymphedema (BCRL). Despite their clinical relevance, the precise timelines for patient improvement following these interventions remain rather unexplored. Therefore, the goal of this study was to compare the long-term outcomes and improvement patterns over time of VLNT versus LVA to lay open potential differences and aid in personalized counseling of future patients. A prospectively maintained, encrypted database was analyzed for patients with chronic BCRL treated with either VLNT or LVA with a minimum follow-up of one year. Patient-specific variables, such as body weight and circumferential arm measurements at distinct locations on both arms were documented preoperatively and on regular postoperative outpatient follow-ups. This study comprised 112 patients, of which 107 patients fully completed the one-year follow-up period. Both VLNT and LVA achieved significant arm size reductions. LVA showed an early peak in effectiveness within the first three months, followed by a subsequent decrease and eventual stabilization. Contrarily, VLNT exhibited a distinct pattern with two significant peaks at three and eighteen months. VLNT and LVA are both effective in long-term lymphedema management, yet they demonstrate marked differences in the timing of improvement. VLNT shows a delayed but more durable response, in contrast to the greater but shorter-lasting surge in effectiveness achieved by LVA. Interestingly, VLNT demonstrates an earlier onset of therapeutic impact than previously understood.

Cross-cultural Adaption of the Indonesian Version of the Withdrawal Assessment Tool Version-1

Background Sedative and analgesic medications are commonly administered in the Pediatric Intensive Care Unit (PICU) but can cause complications, such as Iatrogenic Withdrawal Syndrome (IWS). The Withdrawal Assessment Tool Version-1 (WAT-1) questionnaire is a validated and reliable diagnostic tool for IWS, but it is not yet available in the Indonesian language. Methods This observational cross-sectional study was conducted in two phases at Ciptomangukusumo Hospital, Jakarta, Indonesia. The initial phase involved translating the WAT-1 and State Behavioral Scale (SBS) instrument into Indonesian. Subsequently, the validity and reliability of the Indonesian version of WAT-1 were tested on 30 patients who received sedative and analgesic medications for at least five consecutive days in the PICU. Evaluations were performed by two groups of nurses: PICU nurses and training nurses. Results The Indonesian version of WAT-1 was found to be valid and reliable. The validity showed correlations ranging from good to very strong (r = 0.490 to 0.836) among PICU nurses and strong correlations (r = 0.634 to 0.808) among trained nurses. The WAT-1 questionnaire demonstrated reliability with Cronbach's alpha values of 0.791 for PICU nurses and 0.785 for trained nurses. The Intraclass Correlation Coefficient (ICC) for WAT-1 indicated very good to excellent consistency in assessments, and the ICC for SBS indicated excellent consistency. Conclusion The Indonesian version of WAT-1 and SBS is a valid and reliable diagnostic tool for detecting Iatrogenic Withdrawal Syndrome in Children.

The Interactive Effects of Nutrient Density and Breed on Growth Performance and Gut Microbiota in Broilers

This study investigated whether variations in growth response to low nutrient density across breeds are linked to microbiota regulation. Arbor Acres (AA) and Beijing-You (BY) were fed high- (HN) and low-nutrient (LN) diets from day (d) 0 to d42. Body weight, feed intake, and intestinal measurements were recorded, and microbiota from the ileum and cecum were analyzed on d7, d21, and d42. Results showed that AA broilers had greater growth performance with a lower feed conversion ratio (FCR) and greater average daily gain (ADG) than BY chickens. The LN diet negatively affected AA broiler growth due to impaired intestinal development, while BY chickens compensated by increasing feed intake. Microbiota composition was primarily affected by breed than by nutrient density, with AA broilers having more beneficial bacteria and BY chickens having more short-chain fatty acid (SCFA)-producing bacteria. The LN diets reduced anti-inflammatory bacteria such as Shuttleworthia and Eisenbergiella in the cecum on d7. By d21, LN diets decreased Lactobacillus and increased proinflammatory Marvinbryantia, potentially impairing growth. However, LN diets enriched SCFA-producing bacteria like Ruminococcaceae_UCG.013, Eisenbergiella, and Tyzzerella in BY chickens and Faecalitalea in AA broilers by d21, which may benefit gut health. By d42, LN diets reduced genera linked to intestinal permeability and fat deposition, including Ruminococcus_torques_group, Romboutsia, Erysipelatoclostridium, and Oscillibacter. Additionally, LN diets enriched Christensenellaceae_R-7_group in AA broilers, associated with intestinal barrier integrity, and increased anti-inflammatory bacteria Alistipes and Barnesiella in AA broilers and BY chickens, respectively, by d42. Overall, AA broilers were more susceptible to reduced nutrient density due to impaired intestinal development, while BY chickens adapted better by increasing feed intake. The microbiota responses to low nutrient density varied over time, potentially negatively affecting gut health in the early stage and growth in the middle stage but possibly improving lipid deposition and gut health in the middle and late stages.

From digital literacy to digital competence: The structure of Teacher Digital Competence (TDC)

ABSTRACT This study investigates the impact of digital literacy on the digital competence of 380 Chinese university teachers. Using the Scale of Digital Literacy (SDL) and Scale of Teacher Digital Competence (STDC), the study implements a training programme based on the Teacher Digital Competence (TDC) framework. Results show that higher digital literacy correlates with increased STDC indicators. Group A, with lower initial digital literacy, sees minimal improvements, emphasising the importance of baseline digital literacy. However, Groups B and C, with intermediate to advanced digital literacy, exhibit significant enhancements in all sub-scales. The study highlights the effectiveness of tailored training for teachers with varying digital literacy levels, offering valuable insights for educational initiatives.

Oxidative stress and apoptosis of the spinal cord in a rat model of retinoic acid-induced neural tube defects.

Neural tube defects (NTDs) are severe congenital anomalies that significantly impact the central nervous system, arising from the neural tube's failure to close during early embryogenesis. In this study, we investigated NTDs and associated pathophysiological mechanisms in foetal rats following exposure to all-trans retinoic acid (atRA). Out of 168 embryos from 15 pregnant rats in the experimental group, 78% displayed NTDs with notable spinal deformities, primarily in the lumbar-sacral region, similar to human cases. Body weight and crown-rump length (CRL) measurements indicated significant growth impairment in the NTD group compared to controls, while the atRA-treated group without NTDs showed no notable differences in growth. Immunohistochemistry (IHC) results demonstrated decreased NeuN and PCNA expression in the NTD group's spinal cord. Oxidative stress markers showed markedly reduced superoxide dismutase (SOD) and glutathione peroxidase (GSH-px) activity, alongside increased malondialdehyde (MDA) levels in the NTD group, indicating heightened oxidative stress. Analysis of apoptosis-related proteins revealed elevated Bax and caspase-3 levels, reduced Bcl-2 and lower poly (ADP-ribose) polymerase (PARP) in the NTD group, suggesting a pronounced shift towards proapoptotic pathways, potentially contributing to NTD progression. Our findings indicate that oxidative stress and apoptosis play significant roles in the development of NTDs. Future investigations should aim to pinpoint critical regulatory genes or proteins that might be targeted for therapeutic interventions to alleviate oxidative stress and apoptosis in NTD development.

Test Weight Validation in Preterm Infants.

Objective: Accuracy in the assessment of feed intake is important for preterm infants at risk of growth failure. Clinical observation tools are unvalidated in this population, and test weight measurement may be inaccurate in preterm infants taking small feed volumes. Methods: Test weights were performed to assess agreement between weights using a standardized protocol and a feed of known weight in preterm infants (born at <35 weeks gestational age [GA]) during their transition to oral feeding. Reproducibility was assessed using two repeated measurements in each participant. Agreement between test weights and known feed weights was assessed, and minimal detectable change was calculated. Results: Thirty-eight preterm infants (GA 30 + 5 (28-33 + 1), birth weight 1574 g (+/- 671 g)) were recruited and had test weights performed at CGA 35 + 3 (± 10 days). Each infant was weighed twice before and twice after each measured feed, and a high degree of reproducibility was found for both the paired pre-feed weights, ICC = 0.99 [0.99-0.99] and the paired post-feed weights, ICC = 0.99 [0.99-0.99]. The mean absolute difference between test weight and feed weight was 1.7 g (±2.2). We calculated the minimum detectable change as 0.96 g, representing the magnitude of change below which there is more than 95% chance that no real change occurred. Conclusions: During the establishment of oral feeds, a standardized protocol at the bedside for repeated pre- and post-feed weights demonstrated a high degree of reproducibility. Based on our data, test weight measurements are appropriate for use in this preterm population during the establishment of oral feeds.

Development of a Deployable Reflector Antenna for the Synthetic Aperture Radar Satellite, Part 2: Manufacturing and Qualification of the Main Reflector Using a Honeycomb Sandwich Composite Structure

A deployable reflector antenna (DR-A) is a structure that can be stored in a large-diameter Synthetic Aperture Radar (SAR) antenna and be mounted onto a launch vehicle. Considering the performance of the launch vehicle, it is necessary to develop a lightweight, high-performance antenna structure. The solid-type deployable reflector antenna is composed of a number of unit main reflectors. To reduce the weight of the antenna, a lightweight main reflector must be developed. In this paper, following “Development of Deployable Reflector Antenna for the SAR Satellite (Part 1)”, the manufacturing and qualification of the main reflector using honeycomb sandwich composites are described. Four types of composite main reflectors were manufactured with variables in the manufacturing process. The manufacturing variables include the curing process of the structure, the application of an adhesive film between the sheet and the core, and the venting path inside of the sandwich core. After manufacturing the main reflector, we performed weight measurements, non-destructive testing (NDT), surface error measurement using a Coordinate Measurement Machine (CMM), and modal testing for each type of composite main reflector. Through the research and development process, we found that a perforated hole is necessary when excluding the adhesive film during bonding of an aramid core and a CFRP sheet, and a lightweight composite reflector could be developed through this process. We selected the main reflector with the best performance and developed a composite main reflector that can be applied to satellites.

Reliability of the Unilateral Hearing Loss in Youth Instrument for Children With Single-Sided Deafness.

While general practice parameter recommendations for children with unilateral hearing loss or single-sided deafness (SSD) have been published, clinically utilized subjective instruments specifically designed to assess this population are scarce. Treatment options are evaluated using audiometric data, speech perception data, and quality of life instruments. The Unilateral Hearing Loss in Youth (uniHELO) is a subjective assessment instrument that aims to evaluate the listening challenges in this population, but it has not yet been studied in a clinical setting. This study examined the reliability of the uniHELO among children with SSD. This was a prospective within-subject study. Nine patients with SSD, aged 8-14 years, were enrolled. Participants had not used a personal hearing device for at least 6 months prior to enrollment. The uniHELO instrument was administered at two clinic visits separated by 3-4 weeks. For comparison, the Pediatric and Parent Speech, Spatial, and Qualities of Hearing Scale (SSQ) instruments were administered during the same visits. uniHELO scores were not significantly different between the first and second visits. The correlations of scale scores over time were: .96 for the uniHELO, which suggests excellent test-retest reliability; .84 for the Parent SSQ, which also suggests excellent test-retest reliability; and .27 for the Pediatric SSQ, which suggests poor test-retest reliability compared to the Parent SSQ and uniHELO. Within-subject scale uniHELO scores between clinic visits showed excellent test-retest reliability across items. The test-retest reliability scores for the uniHELO were also stronger than those for the Parent and Pediatric SSQ. These data support the use of the uniHELO to evaluate listening challenges in children with SSD.

Supplementation of lysophospholipids in calf starter: effects on growth performance, blood metabolites, health, and ruminal ammonia nitrogen concentration

The aim of the current study was to evaluate the effects of a commercial mixture of Lysophospholipids (LPL) in calf starter on performance, blood metabolites, antioxidant capacity, liver enzymes concentration, and health status of pre-weaning dairy calves. Forty-eight newborn female Holstein calves (37.5 ± 2.9kg of body weight) were randomly assigned to four treatments (12 replicates), which included the control (CON, without additive) and a commercial blend of LPL at 0.5, 1, and 1.5g/kg of starter feed. The body weight of the calves was measured using a digital scale on days 15, 30, 45, and d 63 of the experimental period to calculate the average daily gain (ADG). The individual starter intake and fecal score were measured daily. Blood samples were collected at 30 and 63 days, while fecal samples were collected for four consecutive days after weaning to measure nutrient digestibility. The treatments did not significantly afffect the total dry matter and starter intake. However, the supplementation of LPL resulted in an increase in the ADG and improved feed efficiency (FE, from1-63 d) compared to the CON group. The addition of LPL did not have any significant impact on the apparent digestibility of dry matter (DM), and organic matter (OM). Eether extract (EE) digestibility tended to increase with the addition of LPL. Calves that received starter feed containing 0.5g/kg of LPL had higher superoxide dismutase activity at 30 d of age compared to the intake.CON group. Additionally, the average fecal score significantly decreased in calves fed 0.5 and 1.5g/kg LPL compared with the CON group. These findings suggest that the inclusion of LPL at an average dose of 1g/kg of calf starter can improve the performance of pre-weaning Holstein dairy calves.

Atomic mechanisms for the fracture of AlMo0.5NbTa0.5TiZr refractory high entropy superalloy

Refractory high entropy superalloys (RHESs), known for their excellent high temperature performance, exhibit promising characteristics but are challenged by significant brittleness. Efforts to enhance plasticity through microstructure regulation have achieved only limited success, largely due to the unclear underlying fracture mechanisms of the superstructure. In this study, we systematically investigate the fracture mechanisms of the AlMo0.5NbTa0.5TiZr RHES from microscopic to electronic scales. Interestingly, both experimental and simulation results reveal that the ordered B2 phase demonstrates non-negligible plastic deformation capabilities during fracture, including deformation twinning and amorphization. Despite this, the fracture resistance of the B2 phase is lower compared to the A2/B2 interface and disordered A2 phase, even though the A2 phase shows less twinning and amorphization. Ab initio molecular dynamics simulations, combined with electronic behavior analysis, indicate that bonds involving Al and Zr in the B2 phase often exist in an anti-bonding state, making them more prone to breaking under load. This study provides deeper insights into the fracture mechanisms of the A2/B2 superstructure and its constituent phases at both atomic and electronic levels, offering a systematic approach to improving the fracture properties of such RHESs.

Stock of Nuts/Bolts System With A Load Cell Sensor of Digital Scale As An Iot-Based

The passage highlights the importance of having a reliable supply of nuts and bolts for Micro, Small, and Medium Enterprises (MSMEs) involved in the manufacturing of appropriate technology tools. Nuts and bolts are critical components in the production process of such manufacturing. Therefore, it is essential to ensure their constant availability to avoid interruptions in the workflow. Currently, many MSMEs still monitor their stock levels manually. This manual method has its drawbacks, as stock levels can sometimes go unnoticed, leading to stockouts when the components are needed. When stock runs out unexpectedly, it can cause delays, as additional time is required to purchase more supplies from wholesalers. In this study, a digital scale with a load cell sensor was developed as a medium for taking inventory or stocking bolts and nuts. This device features several buttons: a button for selecting the size of bolts or nuts, a button for choosing between stocking or taking items, and a button for displaying stock information of bolts or nuts in the warehouse. The results from this digital scale are sent to a website using the Internet of Things (IoT) system as a communication medium between the digital scale and the monitoring website. The results of this study show that the digital scale has an accuracy of 99.95%, and the accuracy of the counted items or stock is 100%.

Exploring Digital Stress of Finnish Adolescents and Their Parents

Background/Objectives: The way people communicate has significantly changed due to technological advances and penetration of cell phones and broadband connection into everyday activities. Nowadays, individuals are constantly connected through the Internet. This influences social experiences, self and social identity, and can cause digital stress, which often leads to negative emotions, psychosomatic outcomes, and diseases. It is a matter of concern for the adolescents and their families. This paper investigates how Information and Communication Technologies (ICTs) and social media influence adolescents’ and parents’ digital stress and anxiety. Methods: Based on two digital stressors scales, a 30-item questionnaire was created. A quantitative analysis of data deriving from 164 Finnish adolescents and 53 of their parents regarding digital stress was conducted. Results: “Privacy Intrusion”, “Availability stress/Online vigilance”, and “Usefulness” were the most essential stressor factors for both students and parents. Additionally, the most significant stressor factors for students were the “Fear of Missing Out/FoMO” and “Approval Anxiety” factors while for parents were the “Safety/Security” and “Technical Support” factors. No significant differences were observed between the overall digital stress of adolescents and parents. In contrast to the existing literature, no connection between “Connection (Information) Overload” and digital stress was found. Conclusions: This paper contributes to debates regarding the effects of the use of digital resources, ICTs, and social media on processes at school, at work, and at home. The findings of our study confirm and further validate those of previous studies with the exception of “Connection (Information) Overload”, which needs to be further investigated to understand the reasons behind it.

Nutrition is one of the aspects that affects the growth and development of children. Nutritional status is an important health indicator, and vulnerable groups facing nutritional issues include children under five years old. Signs of developmental disorders include slow maturation of nerve cells, delayed motor skills, decreased intelligence, sluggish social reactions, and difficulties in speaking, language, and independence. Nutritional problems in children according to weight-for-age (BB/U) include undernutrition, short stature (TB/U), and underweight (BB/TB). The purpose of this study is to determine the relationship between nutritional status and the development of children aged 4-5 years at Aisyiyah Bustanul Atfal 2 Kindergarten. The subjects of this study are all children aged 4-5 years enrolled at Aisyiyah Bustanul Atfal 2 Kindergarten in Labuhan Ratu Baru Way, Jepara District, totaling 54 children. This study uses total sampling technique. The methodology employed is quantitative research with a cross-sectional design, and data collection was conducted using a microtoise to assess height, a digital scale to measure weight, and the KPSP questionnaire to evaluate nutritional status in relation to child development. The study findings indicate a significant relationship between nutritional status according to weight-for-age (BB/U) and child development (p=0.000) with a strong negative correlation (r= -0.748). There is a significant correlation between nutritional status according to height-for-weight (BB/TB) and child development (p=0.000) with a strong positive correlation (r=0.610). There is also a significant relationship regarding the correlation between nutritional status according to height-for-age (TB/U) and child development (p=0.025) with a weak positive correlation (r=0.304). It is advisable to provide education and early detection of developmental issues in toddlers experiencing nutritional disorders.

Effect of Feeding Process Stimulation on Oral Preparedness Readiness in Premature Infants

BACKGROUND: Most preterm infants do not have proper sucking, swallowing, and breathing coordination which caused delay in oral feeding readiness. OBJECTIVE: The objective of this study was to analyze the influence of feeding stimulation on the readiness of premature infant’s oral feeding. METHOD: This study was a true experimental study that involved 44 preterm infants born between 32-34 weeks of gestational age, devided in two groups. Twenty two infants in the intervention group received positioning (mid-line control symmetric) and oral feeding stimulation, while the control group received only positioning intervention. Oral stimulation was given 8 times a day for 7 days, before starting the oral feeding program. Oral feeding readiness was measured by using a modified early feeding scale (EFS) instrument on the first and the seventh days. Data analysis using t-test dependent, independent t-test, and Mc Nemar test. RESULT: The results showed that there was a significant effect of the intervention on EFS score (p &lt;0.001) and also on preterm infant’s oral feeding readiness (p = 0.002). The results also showed that there was an effect of intervention on the length of stay (p=0.001). CONCLUSION: Early oral feeding stimulation improves the infant’s oral feeding readiness and shortens the infant’s length of stay. Researchers recommend stimulation of the feeding process as an independent nursing intervention in caring for premature infants.

Proximal Fibula Resection for Tumors—Case Series and Technical Note

Background: The resection of tumors of the proximal fibula includes the removal of the lateral collateral ligament (LCL) and biceps femoris tendon (BFT) attachment. The aim was to describe and evaluate a surgical reconstruction technique in terms of functional outcome and knee joint stability. Methods: We analyzed the outcome of six patients, treated by a proximal fibula resection. The reconstruction of the attachments of the LCL and BFT was performed with two suture anchors, fixed onto the tibia at the level of the proximal tibiofibular joint (PTFJ). The postoperative knee flexion strength as well as the lateral knee joint stability were compared to the contralateral side using a digital scale and stress x-ray. Patient-reported outcome measures and postoperative complications were documented. Results: No lateral instability and no significant loss of knee flexion strength could be observed (p = 0.075). One persistent postoperative peroneus paresis was reported. High functional outcome was achieved with a mean MSTS score of 92.2%. Conclusions: The resection of the proximal fibula with the reinsertion of the LCL and the BFT using bone anchors in the PTFJ seems to provide a good functional outcome, with a low level of associated comorbidities.

Efficient and Accurate Brain Tumor Classification Using Hybrid MobileNetV2–Support Vector Machine for Magnetic Resonance Imaging Diagnostics in Neoplasms

Background/Objectives: Magnetic Resonance Imaging (MRI) plays a vital role in brain tumor diagnosis by providing clear visualization of soft tissues without the use of ionizing radiation. Given the increasing incidence of brain tumors, there is an urgent need for reliable diagnostic tools, as misdiagnoses can lead to harmful treatment decisions and poor outcomes. While machine learning has significantly advanced medical diagnostics, achieving both high accuracy and computational efficiency remains a critical challenge. Methods: This study proposes a hybrid model that integrates MobileNetV2 for feature extraction with a Support Vector Machine (SVM) classifier for the classification of brain tumors. The model was trained and validated using the Kaggle MRI brain tumor dataset, which includes 7023 images categorized into four types: glioma, meningioma, pituitary tumor, and no tumor. MobileNetV2’s efficient architecture was leveraged for feature extraction, and SVM was used to enhance classification accuracy. Results: The proposed hybrid model showed excellent results, achieving Area Under the Curve (AUC) scores of 0.99 for glioma, 0.97 for meningioma, and 1.0 for both pituitary tumors and the no tumor class. These findings highlight that the MobileNetV2-SVM hybrid not only improves classification accuracy but also reduces computational overhead, making it suitable for broader clinical use. Conclusions: The MobileNetV2-SVM hybrid model demonstrates substantial potential for enhancing brain tumor diagnostics by offering a balance of precision and computational efficiency. Its ability to maintain high accuracy while operating efficiently could lead to better outcomes in medical practice, particularly in resource limited settings.
