Background: Exercise-induced fatigue arises primarily from energy substrate depletion and the accumulation of metabolites such as lactate and ammonia, which impair performance and delay recovery. Emerging evidence implicates gut microbiota modulation—particularly via probiotics—as a means to optimize host energy metabolism and accelerate clearance of fatigue-associated by-products. Objective: This study aimed to determine whether live or heat-inactivated Lacticaseibacillus paracasei NB23 can enhance exercise endurance and attenuate fatigue biomarkers in a murine model. Methods: Forty male Institute of Cancer Research (ICR) mice were randomized into four groups (n = 10 each) receiving daily gavage for six weeks with vehicle, heat-killed NB23 (3 × 10¹⁰ cells/mouse/day), low-dose live NB23 (1 × 10¹⁰ CFU/mouse/day), or high-dose live NB23 (3 × 10¹⁰ CFU/mouse/day). Forelimb grip strength and weight-loaded swim-to-exhaustion tests assessed performance. Blood was collected post-exercise to measure serum lactate, ammonia, blood urea nitrogen (BUN), and creatine kinase (CK). Liver and muscle glycogen content was also quantified, and safety was confirmed by clinical-chemistry panels and histological examination. Results: NB23 treatment produced dose-dependent improvements in grip strength (p < 0.01) and swim endurance (p < 0.001). All NB23 groups exhibited significant reductions in post-exercise lactate (p < 0.0001), ammonia (p < 0.001), BUN (p < 0.001), and CK (p < 0.0001). Hepatic and muscle glycogen stores rose by 41–59% and 65–142%, respectively (p < 0.001). No changes in food or water intake, serum clinical-chemistry parameters, or tissue histology were observed. Conclusions: Our findings suggest that both live and heat-treated L. paracasei NB23 may contribute to improved endurance performance, increased energy reserves, and faster clearance of fatigue-related metabolites in our experimental model. However, these results should be interpreted cautiously given the exploratory nature and limitations of our study. Full article

Objective: Esophageal cancer (EC) is difficult to visually identify, rendering early detection crucial to avert the advancement and decline of the patient’s health. Methodology: This work aimed to acquire spectral information from EC images via Spectrum-Aided Visual Enhancer (SAVE) technology, which improves imaging beyond the limitations of conventional White-Light Imaging (WLI). The hyperspectral data acquired using SAVE were examined utilizing sophisticated deep learning methodologies, incorporating models such as YOLOv8, YOLOv7, YOLOv6, YOLOv5, Scaled YOLOv4, and YOLOv3. The models were assessed to create a reliable detection framework for accurately identifying the stage and location of malignant lesions. Results: The comparative examination of these models demonstrated that the SAVE method regularly surpassed WLI for specificity, sensitivity, and overall diagnostic efficacy. Significantly, SAVE improved precision and F1 scores for the majority of the models, which are essential measures for enhancing patient care and customizing effective medicines. Among the evaluated models, YOLOv8 showed exceptional performance. YOLOv8 demonstrated increased sensitivity to squamous cell carcinomas (SCCs), but YOLOv5 provided reliable outcomes across many situations, underscoring its adaptability. Conclusions: These findings highlight the clinical importance of combining SAVE technology with deep learning models for esophageal cancer screening. The enhanced diagnostic accuracy provided by SAVE, especially when integrated with CAD models, offers potential for improving early detection, precise diagnosis, and tailored treatment approaches in clinically pertinent scenarios.

Background/Objectives: Gastrointestinal diseases (GID), such as oesophagitis, polyps, and ulcerative colitis, contribute significantly to global morbidity and mortality. Conventional diagnostic methods employing white light imaging (WLI) in wireless capsule endoscopy (WCE) provide limited spectrum information, therefore influencing classification performance. Methods: A new technique called Spectrum Aided Vision Enhancer (SAVE), which converts traditional WLI images into hyperspectral imaging (HSI)-like representations, hence improving diagnostic accuracy. HSI involves the acquisition of image data across numerous wavelengths of light, extending beyond the visible spectrum, to deliver comprehensive information regarding the material composition and attributes of the imaged objects. This technique facilitates improved tissue characterisation, rendering it especially effective for identifying abnormalities in medical imaging. Using a carefully selected dataset consisting of 6000 annotated photos taken from the KVASIR and ETIS-Larib Polyp Database, this work classifies normal, ulcers, polyps, and oesophagitis. The performance of both the original WLI and SAVE transformed images was assessed using advanced deep learning architectures. The principal outcome was the overall classification accuracy for normal, ulcer, polyp, and oesophagitis categories, contrasting SAVE-enhanced images with standard WLI across five deep learning models. Results: The principal outcome of this study was the enhancement of diagnostic accuracy for gastrointestinal disease classification, assessed through classification accuracy, precision, recall, and F1 score. The findings illustrate the efficacy of the SAVE method in improving diagnostic performance without requiring specialised equipment. With the best accuracy of 98% attained using EfficientNetB7, compared to 97% with WLI, experimental data show that SAVE greatly increases classification metrics across all models. With relative improvement from 85% (WLI) to 92% (SAVE), VGG16 showed the highest accuracy. Conclusions: These results confirm that the SAVE algorithm significantly improves the early identification and classification of GID, therefore providing a potential development towards more accurate, non-invasive GID diagnostics with WCE.

This study evaluated the effects of fermented banana agro-waste silage (BAWS) in finishing diets for KHAPS pigs (Duroc × MeiShan hybrid). BAWS was produced via 30 days of anaerobic fermentation of disqualified banana fruit, pseudostem, and wheat bran, doubling crude protein content and generating short-chain fatty acids, as indicated by a satisfactory Flieg’s score. Thirty-six pigs were assigned to control (0%), 5%, or 10% BAWS diets formulated to meet NRC nutritional guidelines. Over a 70-day period, BAWS inclusion caused no detrimental effects on growth performance, carcass traits, or meat quality; a transient decline in early-stage weight gain and feed efficiency occurred in the 10% group, while BAWS-fed pigs demonstrated reduced backfat thickness and increased lean area. Fore gut microbiome analysis revealed reduced Lactobacillus and elevated Clostridium sensu stricto 1, Terrisporobacter, Streptococcus, and Prevotella, suggesting enhanced fiber and carbohydrate fermentation capacity. Predictive COG (clusters of orthologous groups)-based functional profiling showed increased abundance of proteins associated with carbohydrate transport (COG2814, COG0561, COG0765) and stress-response regulation (COG2207). These results support BAWS as a sustainable feed ingredient that maintains production performance and promotes fore gut microbial adaptation, with implications for microbiota-informed nutrition and stress resilience in swine.

Background: Intra-abdominal infections (IAIs) caused by Stenotrophomonas maltophilia have rarely been reported. This study aimed to describe the clinical characteristics and risk factors for mortality among patients with S. maltophilia IAIs. Methods: A retrospective study was conducted on inpatients with IAIs caused by S. maltophilia at Tri Service General Hospital from 2004 to 2017. Clinical and microbiologic data of the included cases were reviewed via medical charts and microbiology databases. Multivariable logistic regression analyses were performed to identify risk factors for in-hospital death. Results: In total, 110 patients were diagnosed with S. maltophilia IAIs. Malignancy (56.3%) and liver cirrhosis (35.3%) were the most commonly identified underlying diseases. The major causes of S. maltophilia IAIs were biliary tract infection (42.7%), recent abdominal surgery (35.4%), and spontaneous bacterial peritonitis (20.0%). Polymicrobial infections were observed in 84 (76.4%) patients. In addition to S. maltophilia, co-cultured bacteria (n = 140) included Enterobacterales, representing 19.3% (27/140) of the total isolates, and non-fermentative aerobes, comprising 29.3% (41/140). In addition, anaerobic bacteria and fungi accounted for 9.2% (13/140) and 10% (14/140), respectively. The overall mortality rate was 40.9%. Multivariable logistic regression analysis revealed that high Sequential Organ Failure Assessment scores and malignancies were independent risk factors for mortality, while the immediate administration of appropriate antibiotics targeting S. maltophilia was a protective factor (p < 0.05). Conclusions: Patients with an underlying malignancy or liver cirrhosis were at risk for IAIs caused by S. maltophilia. The prompt initiation of effective antibiotics against S. maltophilia is critical for achieving favorable outcomes. Full article

Capsule endoscopy (CE) has revolutionized gastrointestinal (GI) diagnostics by providing a non-invasive, patient-centered approach to observing the digestive tract. Conceived in 2000 by Gavriel Iddan, CE employs a diminutive, ingestible capsule containing a high-resolution camera, LED lighting, and a power supply. It specializes in visualizing the small intestine, a region frequently unreachable by conventional endoscopy. CE helps detect and monitor disorders, such as unexplained gastrointestinal bleeding, Crohn’s disease, and cancer, while presenting a lower procedural risk than conventional endoscopy. Contrary to conventional techniques that necessitate anesthesia, CE reduces patient discomfort and complications. Nonetheless, its constraints, specifically the incapacity to conduct biopsies or therapeutic procedures, have spurred technical advancements. Five primary types of capsule endoscopes have emerged: steerable, magnetic, robotic, tethered, and hybrid. Their performance varies substantially. For example, the image sizes vary from 256 × 256 to 640 × 480 pixels, the fields of view (FOV) range from 140° to 360°, the battery life is between 8 and 15 h, and the frame rates fluctuate from 2 to 35 frames per second, contingent upon motion-adaptive capture. This study addresses a significant gap by methodically evaluating CE platforms, outlining their clinical preparedness, and examining the underexploited potential of artificial intelligence in improving diagnostic precision. Through the examination of technical requirements and clinical integration, we highlight the progress made in overcoming existing CE constraints and outline prospective developments for next-generation GI diagnostics.

Objective: Attention-Deficit/Hyperactivity Disorder (ADHD) is a common neurodevelopmental disorder in children, characterized by inattention, hyperactivity, and impulsive behavior. In recent years, studies have shown that patients with ADHD often experience sleep problems, raising clinical interest in the potential role of polysomnography (PSG) in the diagnosis and management of ADHD. This study examines polysomnographic findings in children with ADHD who present with diverse sleep complaints. Methods: A cohort of children aged younger than 18 years, diagnosed with ADHD based on DSM-5 criteria, underwent overnight polysomnography. The study assessed various sleep parameters, including sleep latency, sleep efficiency, total sleep time, and the presence of sleep-disordered breathing. Results: A retrospective analysis was conducted on 36 children (29 boys and 7 girls) aged 6 to 14 years, diagnosed with ADHD, who underwent polysomnography between 2021 and 2024. Polysomnographic findings revealed that 77.78% of the children demonstrated significant snoring. Furthermore, 50.0% were diagnosed with obstructive sleep apnea syndrome (OSAS). In addition, eight children exhibited parasomnias. Among them, six had bruxism, three were diagnosed with periodic limb movement disorder (PLMD), and two experienced sleep talking. Other notable sleep-related conditions included two cases of narcolepsy, one case of prolonged sleep onset latency, and one case of central apnea syndrome. Total sleep time (TST) was significantly longer in females compared to males (400.71 ± 32.68 min vs. 361.24 ± 41.20 min, p = 0.0215), whereas rapid eye movement (REM) latency was longer in males compared to females (118.62 ± 55.60 min vs. 78.57 ± 27.82 min, p = 0.0194). These findings highlight the high prevalence of sleep-disordered breathing (SDB) in children with ADHD who present with sleep disturbances. Furthermore, sleep quality, as indicated by longer TST and shorter REM latency, appears to be better in females with ADHD. Conclusions: The findings of this study underscore the critical role of polysomnography (PSG) in the assessment of children with ADHD. PSG provides an objective evaluation of sleep abnormalities commonly associated with ADHD, which may influence symptom manifestation and treatment outcomes. Notably, the results suggest that females with ADHD exhibit better sleep quality, as indicated by longer total sleep time (TST) and shorter rapid eye movement (REM) latency compared to males. We recommend incorporating polysomnography (PSG) into the comprehensive assessment of children with ADHD who present with significant sleep disturbances. Further research is warranted to investigate the impact of targeted interventions for sleep abnormalities on ADHD symptoms, prognosis, and potential sex-specific differences. Full article

Background and Objectives: Post-transplant anastomotic pseudoaneurysms are a rare but serious complication of renal transplantation, typically requiring graft sacrifice. This case report demonstrates a novel hybrid approach for managing a mycotic pseudoaneurysm while preserving graft function. Case report: A 56-year-old male developed a pseudoaneurysm at the anastomotic site after cadaveric kidney transplantation, presenting with recurrent infections and declining renal function. Imaging confirmed the pseudoaneurysm. A hybrid strategy combining femoral–femoral bypass with a polytetrafluoroethylene graft, percutaneous transluminal angioplasty with stenting, and coil embolization was performed. Results: The intervention successfully isolated the pseudoaneurysm and preserved graft function. Post-procedure, serum creatinine levels improved, stabilizing at 2.3 mg/dL during follow-up. Imaging confirmed no residual flow in the aneurysm, and vascular complications were absent. Conclusions: This report highlights a successful combined surgical and endovascular approach for treating mycotic pseudoaneurysms, preserving graft function and restoring limb blood flow. This strategy offers a promising alternative for managing complex post-transplant complications, though long-term outcomes require further evaluation. Full article

Background/Objectives: Sodium glycerophosphate improves the adverse side effects of parenteral nutrition. Therefore, this study aimed to evaluate different outcomes, including metabolic bone disease and electrolyte imbalance, associated with the use of sodium glycerophosphate or inorganic phosphate in parenteral nutrition for preterm neonates. Methods: This retrospective cohort study enrolled 402 newborns admitted to the neonatal intensive care unit of one medical center between January 2019 and September 2021. Of them, 205 received sodium glycerophosphate as parenteral nutrition, while the other 197 received inorganic phosphate. Baseline characteristics and growth parameters, including body weight, body length, and head circumference in the first year of life; calcium and phosphate content of parenteral nutrition in the first 4 weeks; calcium, phosphorus, alkaline phosphatase (ALP), and creatinine levels; and morbidities were compared. Results: During the first 4 weeks, the calcium and phosphate contents of parenteral nutrition were significantly higher in the sodium glycerophosphate vs. inorganic phosphate group. Growth parameters did not differ significantly between groups. The sodium glycerophosphate group showed a higher mean serum phosphate level (4.0 ± 1.2 mg/dL vs. 3.5 ± 1.3 mg/dL, p = 0.001), lower serum ALP level (402.8 ± 202.8 U/L vs. 466.4 ± 228.6 U/L, p = 0.004), lower seizure incidence (4.9% vs. 13.2%, p = 0.003), and higher hypocalcemia incidence (41.5% vs. 31.5%, p = 0.038). However, there were no significant intergroup differences in other common morbidities such as metabolic bone diseases of prematurity, bronchopulmonary dysplasia, electrolyte imbalance, hypoglycemia, retinopathy of prematurity, or intraventricular hemorrhage. Conclusions: Compared to inorganic phosphate, sodium glycerophosphate is associated with higher serum phosphate levels, lower ALP levels, and reduced seizure incidence in premature infants. However, as the study was retrospective and single-center, further randomized controlled trials are needed to confirm these findings. Full article

Bisphenol A (BPA) is a prevalent environmental contaminant found in plastics and known for its endocrine-disrupting properties, posing risks to both human health and the environment. Despite its widespread presence, the impact of BPA on papillary thyroid cancer (PTC) progression, especially under realistic environmental conditions, is not well understood. This study examined the effects of BPA on PTC using a 3D thyroid papillary tumor spheroid model, which better mimicked the complex interactions within human tissues compared to traditional 2D models. Our findings demonstrated that BPA, at environmentally relevant concentrations, could induce significant changes in PTC cells, including a decrease in E-cadherin expression, an increase in vimentin expression, and reduced thyroglobulin (TG) secretion. These changes suggest that BPA exposure may promote epithelial–mesenchymal transition (EMT), enhance invasiveness, and reduce cell differentiation, potentially complicating treatment, including by increasing resistance to radioiodine therapy. This research highlights BPA’s hazardous nature as an environmental contaminant and emphasizes the need for advanced in vitro models, like 3D tumor spheroids, to better assess the risks posed by such chemicals. It provides valuable insights into the environmental implications of BPA and its role in thyroid cancer progression, enhancing our understanding of endocrine-disrupting chemicals. Full article

Concerns about the safety of traditional preservatives in personal care products are driving interest toward self-preserving alternatives. This study explores the potential of B. stenostachya leaf extracts, a natural and biodegradable material, for use in cosmetics. B. stenostachya, a fast-growing bamboo species native to Taiwan, is rich in bioactive compounds, including flavonoids with antimicrobial properties. Leaves were obtained from the Industrial Technology Research Institute (ITRI) in Tainan, Taiwan, and extracted using ultrasonic and Soxhlet methods with water, 50% ethanol, and 95% ethanol. The highest yield was achieved with 50% ethanol at 100 °C. Cytotoxicity was evaluated using the NIH/3T3 mouse fibroblast cell line, with no toxicity observed at dilutions between 1/3200 and 1/400, indicating the extract’s safety for cosmetic use. Antimicrobial activity was tested in accordance with ISO 11930:2019 standards. The extract effectively inhibited Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus pathogens, meeting preservative efficacy Standards A and B for long-term microbial control. Bamboo is a sustainable resource with lower environmental impacts, and its products show promising biodegradability and reduced environmental footprints. This research indicates that the B. stenostachya leaf extract offers a sustainable alternative to chemical preservatives, promoting both environmental sustainability and public health, with the potential for expanded use in natural personal care formulations.

Objectives: To review the outcomes of patients who underwent repeated vertebroplasty (VP) surgery for adjacent segment fractures (ASF), defined as new osteoporotic vertebral fractures occurring at levels immediately above or below a previously treated vertebra. Methods: From 1 January 2018, to 31 December 2020, forty-one patients who developed ASF following initial VP and underwent repeated VP were enrolled in our study. Radiographic measurements included single and two-segment kyphotic angles (SKA and TKA), and anterior and mid-vertebral body height (AVH and MVH). Patient-reported outcomes included back pain assessed with the visual analog scale (VAS) and the Oswestry Disability Index (ODI). Results: The procedure significantly reduced the mean single kyphotic angle (SKA) by 4.8° ± 6.8° (p < 0.01) and the two-segment kyphotic angle (TKA) by 3.0° ± 7.9° (p = 0.02), along with increases in anterior and mid-body height by 0.3 ± 0.5 cm and 0.3 ± 0.6 cm (both p < 0.01). However, there was a slight restoration loss in SKA and TKA at a 20.1-month follow-up. Patient-reported outcomes revealed substantial pain reduction, with the VAS score dropping from 8 to 1 (p < 0.0001) and the mean ODI score improving from 59.7 to 28.9 (p < 0.0001). The complication rate was 34.1%, including nonunion, de novo fractures, cement leakage, and neurological deficits. Additionally, 7.3% of cases necessitated further surgical interventions. Conclusions: Repeated VP for ASF improves vertebral alignment parameters and patient-reported outcomes, but with a high rate of complications and reoperation. Full article

Background/Objectives: Various surgical approaches have been proposed for treating adjacent segment disease (ASD) after lumbar fusion. However, studies using oblique lumbar interbody fusion (OLIF) to treat ASD are lacking. The current study assessed the postoperative outcomes of single-level OLIF for ASD, comparing the results with those for patients undergoing transforaminal lumbar interbody fusion (TLIF). Methods: Patients who underwent single-level OLIF or TLIF for lumbar ASD were retrospectively included. Clinical outcomes, that is, the results of assessments using the Euroqol 5-Dimension quality of life scale (EQ-5D), the Oswestry Disability Index, and the visual analog scale, were evaluated. Radiologic parameters, including disc height (DH), segmental lordosis (SL), segmental coronal angle (SCA), lumbar lordosis, and pelvic incidence–lumbar lordosis mismatch, were also assessed. Results: A total of 65 patients were enrolled: 32 in the OLIF group and 33 in the TLIF group. The median follow-up time was 24.0 months in both groups. The clinical outcomes and radiologic parameters significantly improved in both groups postoperatively. According to intergroup comparisons, the OLIF group had significantly less blood loss and superior improvement in radiologic parameters (DH, SL, and SCA) whereas the TLIF group had significantly shorter operation times. For the OLIF patients who did not undergo posterior decompression, the operation time was similar to that of the TLIF group, but the surgical blood loss and length of hospital stay were significantly reduced compared with the TLIF group. Conclusions: Compared with TLIF, OLIF provides similar clinical outcomes, leads to less surgical blood loss, and has superior radiologic parameters; however, the operation time is significantly longer. OLIF without posterior decompression may be a superior option to TLIF for certain patients. Full article

Zinc cobalt oxide-zinc hydroxide (ZnCo₂O₄-Zn(OH)₂) microspheres were successfully fabricated on carbon cloth via a sample hydrothermal method. The surface morphology of these microspheres and their efficacy in degrading methyl violet were further modulated by varying the thermal annealing temperatures. Adjusting the thermal annealing temperatures was crucial for controlling the porosity of the ZnCo₂O₄-Zn(OH)₂ microspheres, enhancing their photocatalytic performance. Various analytical techniques were utilized to evaluate the physical and chemical properties of the ZnCo₂O₄-Zn(OH)₂ microspheres, including field-emission scanning electron microscopy, energy-dispersive spectroscopy, X-ray diffraction, field-emission transmission electron microscopy, X-ray photoelectron spectroscopy, and UV-vis spectroscopy. Compared to untreated ZnCo₂O₄-Zn(OH)₂ microspheres, those subjected to thermal annealing exhibited increased specific surface area and light absorption capacity, rendering them highly effective photocatalysts under UVC light exposure. Subsequent studies have confirmed the superior performance of ZnCo₂O₄-Zn(OH)₂ microspheres as a reusable photocatalyst for degrading methyl violet and tetracycline. Furthermore, trapping experiments during the photodegradation process using ZnCo₂O₄-Zn(OH)₂ microspheres identified hydroxyl radicals (·OH) and superoxide radicals (·O₂⁻) as the primary reactive species.

The optimal strategy for the microelimination of HCV within community settings remains ambiguous. We evaluated the percentage of participants who achieved linkage to care (LTC) following the conclusion of a screening campaign and examined the diverse factors influencing LTC among these individuals. The effectiveness of recall intervention for the non-LTC population and its barriers were analyzed. We initiated an HCV patient recall program to identify HCV participants who might not be treated after the HCV screening campaign. The program staff recalled HCV participants who were lost to follow-up via telephone from March 2019 to June 2019. They were informed of HCV treatment’s importance, efficacy, availability, and safety. Among 185 participants infected with HCV, 109 (58.9%) obtained LTC. Compared with those who had LTC, those without LTC were older, had lower education levels, were less aware of their HCV infection, less frequently lived in urban areas, and had less health insurance. At the end of the recall program, 125 (67.6%) persons had linkage to care. The proportion of LTC increased by 8.7%. In total, 119 persons had an HCV RNA test, and 82 (68.9%) had viremia. Of the 82 patients with viremia, 78 (95.1%) received antiviral therapy, and 76 (97.4%) achieved a sustained virological response. After a community screening campaign, 59% of participants with anti-HCV-positive tests had LTC. The recall program increased this by 9%. However, 32% of HCV participants still could not be linked to care. Outreach care for non-LTC patients is a method worth trying in order to achieve the microelimination of HCV in rural communities.
