Objective:
This study aims to evaluate and compare the clinical and radiological outcomes of biportal endoscopic transforaminal lumbar interbody fusion (BE-TLIF) using banana-shaped versus straight interbody cages. BE-TLIF has emerged as a minimally invasive technique for treating lumbar spondylolisthesis. Banana-shaped and straight cages are the most commonly used cage types in BE-TLIF; however, their relative clinical and radiological outcomes remain unclear.
Methods:
This retrospective cohort study included 34 patients undergoing single-level BE-TLIF from January 2023 to May 2024. Seventeen patients received banana-shaped cages (group A) and 17 received straight cages (group B). Radiological assessments included disc height (DH), segmental lordosis angle (SLA), lumbar lordosis angle, cage position, and subsidence. Clinical outcomes were evaluated using the visual analogue scale (VAS) for back and leg pain and the Oswestry Disability Index (ODI). Fusion status was evaluated at 12 months postoperatively using computed tomography according to the modified Bridwell grading system.
Results:
Both groups demonstrated significant postoperative improvements in VAS and ODI scores, with no statistically significant differences between the groups. Radiological outcomes, including restoration of DH and SLA, were slightly better in the banana-shaped cage group, but this difference did not reach statistical significance. Straight cages were more often placed anteriorly, whereas banana-shaped cages tended to occupy the midlateral position. Fusion rates were comparable (100% vs. 94.1%, p>0.05), and subsidence occurred in 23.5% of cases in both groups.
Conclusion
Despite differences in cage positioning, banana-shaped and straight cages yielded comparable clinical and radiological outcomes in BE-TLIF. Either cage type can be effectively utilized in BE-TLIF, providing flexibility in surgical planning, particularly in resource-limited settings.

Investigative Magnetic Resonance Imaging 2025;29(4):216-224
Purpose:
To determine the efficacy of apparent diffusion coefficient (ADC) values and ratios (lesion/liver tissue, lesion/splenic tissue, lesion/paraspinal muscle) in differentiating benign from malignant solid liver lesions.
Materials and Methods:
This study retrospectively analyzed data from 115 patients with solid liver lesions who underwent abdominal magnetic resonance imaging (MRI) at a single institution between January 2023 and December 2024. Lesions were classified as benign or malignant based on biochemical tests as well as radiographic and/or histopathologic findings. ADC values and ratios were determined using a 1.5 T MRI scanner.Quantitative variables are presented as mean ± standard deviation or median (interquartile range). Receiver operating characteristic (ROC) analysis was used to determine the cut-off values for ADC value and ratio, for which associated areas under the ROC curve were calculated.
Results:
The present analysis included 115 lesions—36 benign and 79 malignant. The median ADC value of the benign lesions was significantly higher than that of malignant lesions: 1744.5 × 10-6 mm2 /s vs. 1168.0 × 10-6 mm2 /s, respectively. The average lesion-toliver ADC (rADC l), lesion-to-spleen ADC (rADCsp), and lesion-to-paraspinal muscle ADC (rADC m) ratios for the benign lesions were significantly higher than those of malignant lesions: 1.79 vs. 1.09, 2.31 vs. 1.44, and 1.19 vs 0.80, respectively. A threshold of 1416 × 10-6 mm2 /s was used to differentiate benign vs. malignant lesions, with a sensitivity of 83.3% and a specificity of 78.5%. The cut-off values for rADC l, rADCsp, and rADC m were 1.55, 1.95, and 0.97, respectively, with sensitivities of 69.4%, 69.4%, and 83.3% and specificities of 87.3%, 91.1%, and 79.9%, respectively.
Conclusion
ADC metrics obtained from diffusion-weighted MRI effectively distinguished benign from malignant solid liver lesions.

Numerous studies have also revealed that students with a high level of Nomophobia have an increased risk of depression. However, few researchers are interested in examining how the association between nomophobia and depressive symptoms mediates loneliness and self-control. This study aimed to investigate, among Vietnamese High School Students, the association between nomophobia and depressive symptoms, specifically focusing on the role that loneliness and self-control play as potential mediators of that relationship. The Nomophobia Scale (NMP-Q), Depression Anxiety Stress Scale 21 (DASS-21), The UCLA loneliness scale version 3 (UCLA III), and The Brief Self-Control Scale (BSCS) were completed by 556 Vietnamese high school students. Using the PROCESS macro, mediation analyses were conducted to investigate the relationship between variables. According to our findings, nomophobia was positively associated with symptoms of depression, and loneliness and self-control partially mediated this relationship. It is suggested that methods for preventing claustrophobia and depressive symptoms be taken seriously in order to increase self-control and decrease loneliness.

Background: A/H5N1 influenza virus spreads from birds to humans and cause influenza diseases with high mortality rate. Vaccination is the most effective way to protect communities from pandemic, reduce morbidity and mortality. The study of creating A/H5N1 influenza vaccines in conformity with Vietnam was the urgent need. Institute of Vaccine\u2019s Achievement (IVAC) studied production of inactivated influenza vaccine for human on egg-grown from reassortants NIBRG-14. Objectives: In order to produce experimentally A/H5N1 influenza vaccine for human in accordance with WHO requirements and set up a viable process for production of the vaccines. Subjects and method: 10 days embryonated eggs and NIBRG-14 strains were served to the study with LAL method to check endotoxin, Kijehdal method to test total protein. Results: IVAC had produced successfully 5 lots of absorbed vaccine A/H5N1 (FLUVAC) using NIBRG-14 strains and embryonated eggs. Initially, production and quality control processes had been set up at IVAC by applying the recommendations of WHO. Conclusion: The success of the study was a basis of the approval of the government to establish a influenza vaccine manufacturing facilities.
