The efficacy and safety of decompression with interspinous fixation for lumbar spondylolisthesis when compared with posterior lumbar interbody fusion: A pilot study.

Posterior lumbar interbody fusion (PLIF) is widely used to treat degenerative spondylolisthesis because it provides definitive decompression and fixation. Although it has several advantages, it has some disadvantages and risks, such as paraspinal muscle injury, potential intraoperative bleeding, postoperative pain, hardware failure, subsidence, and medical comorbidity. Lumbar decompressive bilateral laminectomy with interspinous fixation (DLISF) is less invasive and can be used on some patients with PLIF, but this has not been reported. To compare the efficacy and safety of DLISF in the treatment of low-grade lumbar spondylolisthesis with that of PLIF. We retrospectively analyzed the medical records of 81 patients with grade I spondylolisthesis, who had undergone PLIF or DLISF and were followed up for more than 1 year. Surgical outcomes, visual analog scale, radiologic outcomes, including Cobb angle and difference in body translation, and postoperative complications were assessed. Forty-one patients underwent PLIF, whereas 40 underwent DLISF. The operative times were 271.0 ±â€…57.2 and 150.6 ±â€…29.3 minutes for the PLIF and DLISF groups, respectively. The estimated blood loss was significantly higher in the PLIF group versus the DLISF group (290.7 ±â€…232.6 vs 122.2 ±â€…82.7 mL, P < .001). Body translation did not differ significantly between the 2 groups. Overall pain improved during the 1-year follow-up when compared with baseline data. Medical complications were significantly lower in the DLISF group, whereas perioperative complications and hardware issues were higher in the PLIF group. The outcomes of DLISF, which is less invasive, were comparable to PLIF outcomes in patients with low-grade spondylolisthesis. As a salvage technique, DLISF may be a good option when compared with PLIF.

Attention Feature Fusion Network via Knowledge Propagation for Automated Respiratory Sound Classification.

Goal: In light of the COVID-19 pandemic, the early diagnosis of respiratory diseases has become increasingly crucial. Traditional diagnostic methods such as computed tomography (CT) and magnetic resonance imaging (MRI), while accurate, often face accessibility challenges. Lung auscultation, a simpler alternative, is subjective and highly dependent on the clinician's expertise. The pandemic has further exacerbated these challenges by restricting face-to-face consultations. This study aims to overcome these limitations by developing an automated respiratory sound classification system using deep learning, facilitating remote and accurate diagnoses. Methods: We developed a deep convolutional neural network (CNN) model that utilizes spectrographic representations of respiratory sounds within an image classification framework. Our model is enhanced with attention feature fusion of low-to-high-level information based on a knowledge propagation mechanism to increase classification effectiveness. This novel approach was evaluated using the ICBHI benchmark dataset and a larger, self-collected Pediatric dataset comprising outpatient children aged 1 to 6 years. Results: The proposed CNN model with knowledge propagation demonstrated superior performance compared to existing state-of-the-art models. Specifically, our model showed higher sensitivity in detecting abnormalities in the Pediatric dataset, indicating its potential for improving the accuracy of respiratory disease diagnosis. Conclusions: The integration of a knowledge propagation mechanism into a CNN model marks a significant advancement in the field of automated diagnosis of respiratory disease. This study paves the way for more accessible and precise healthcare solutions, which is especially crucial in pandemic scenarios.

Fermented Milk Containing Lacticaseibacillus rhamnosus SNU50430 Modulates Immune Responses and Gut Microbiota in Antibiotic-Treated Mice.

Antibiotics are used to control infectious diseases. However, adverse effects of antibiotics, such as devastation of the gut microbiota and enhancement of the inflammatory response, have been reported. Health benefits of fermented milk are established and can be enhanced by the addition of probiotic strains. In this study, we evaluated effects of fermented milk containing Lacticaseibacillus rhamnosus (L. rhamnosus) SNUG50430 in a mouse model with antibiotic treatment. Fermented milk containing 2 × 105 colony-forming units of L. rhamnosus SNUG50430 was administered to six week-old female BALB/c mice for 1 week. Interleukin (IL)-10 levels in colon samples were significantly increased (P < 0.05) compared to water-treated mice, whereas interferon-gamma (IFN-γ) and tumor necrosis factor alpha (TNF-α) were decreased, of mice treated with fermented milk containing L. rhamnosus SNUG50430-antibiotics-treated (FM+LR+Abx-treated) mice. Phylum Firmicutes composition in the gut was restored and the relative abundances of several bacteria, including the genera Coprococcus and Lactobacillus, were increased in FM+LR+Abx-treated mice compared to PBS+Abx-treated mice. Interestingly, abundances of genus Coprococcus and Lactobacillus were positively correlated with IL-5 and IL-10 levels (P < 0.05) in colon samples and negative correlated with IFN-γ and TNF-α levels in serum samples (P < 0.001). Acetate and butyrate were increased in mice with fermented milk and fecal microbiota of FM+LR+Abx-treated mice were highly enriched with butyrate metabolism pathway compared to water-treated mice (P < 0.05). Thus, fermented milk containing L. rhamnosus SNUG50430 was shown to ameliorate adverse health effects caused by antibiotics through modulating immune responses and the gut microbiota.

Establishment of a Dual-Vector System for Gene Delivery Utilizing Prototype Foamy Virus.

Foamy viruses (FVs) are generally recognized as non-pathogenic, often causing asymptomatic or mild symptoms in infections. Leveraging these unique characteristics, FV vectors hold significant promise for applications in gene therapy. This study introduces a novel platform technology using a pseudo-virus with single-round infectivity. In contrast to previous vector approaches, we developed a technique employing only two vectors, pcHFV lacking Env and pCMV-Env, to introduce the desired genes into target cells. Our investigation demonstrated the efficacy of the prototype foamy virus (PFV) dual-vector system in producing viruses and delivering transgenes into host cells. To optimize viral production, we incorporated the codon-optimized Env (optEnv) gene in pCMV-Env and the Woodchuck Hepatitis Virus Posttranscriptional Regulatory Element (WPRE) at the 3' end of the transgene in the transfer vector. Consequently, the use of optEnv led to a significant enhancement in transgene expression in host cells. Additionally, the WPRE exhibited an enhancing effect. Furthermore, the introduced EGFP transgene was present in host cells for a month. In an effort to expand transgene capacity, we further streamlined the viral vector, anticipating the delivery of approximately 4.3 kbp of genes through our PFV dual-vector system. This study underscores the potential of PFVs as an alternative to lentiviruses or other retroviruses in the realm of gene therapy.

Central Nervous System Dissemination of Solitary Sporadic Supratentorial Hemangioblastoma: A Case Report and Literature Review.

We report a patient with whole neuroaxis dissemination of a sporadic supratentorial hemangioblastoma (HB) for more than 15 years. A 68-year-old female patient presented with severe radiating pain in the right leg. Gadolinium-enhanced lumbar spine MRI showed an intradural mass (2.5 cm in diameter) at the L4 level. The patient had been severely disabled for 22 years after a previous intraventricular brain tumor resection. At that time, the diagnosis was angioblastic meningioma, which was thought to be incorrect. At 14 years after the brain surgery, gamma knife radiosurgery was performed three times for newly developed or recurred supratentorial and infratentorial tumors in the cerebrospinal fluid pathway. The patient underwent lumbar spinal surgery, and a gross total removal of the mass was performed, which confirmed the histopathological diagnosis of HB. We reexamined the old histopathological specimen of the intraventricular tumor from 20 years ago and changed the diagnosis from angioblastic meningioma to supratentorial HB. Six months after spinal surgery, the patient underwent a second spinal surgery and brain surgery, and the histopathological diagnosis was HB following both surgeries, which was the same following the first spinal surgery. Here, we report a sporadic supratentorial HB patient who showed cranial and spinal disseminations for more than two decades along with a literature review.

An Analysis of Temporal Trends in Anti-Asian Hate and Counter-Hate on Twitter During the COVID-19 Pandemic.

Recent studies have documented increases in anti-Asian hate throughout the COVID-19 pandemic. Yet relatively little is known about how anti-Asian content on social media, as well as positive messages to combat the hate, have varied over time. In this study, we investigated temporal changes in the frequency of anti-Asian and counter-hate messages on Twitter during the first 16 months of the COVID-19 pandemic. Using the Twitter Data Collection Application Programming Interface, we queried all tweets from January 30, 2020 to April 30, 2021 that contained specific anti-Asian (e.g., #chinavirus, #kungflu) and counter-hate (e.g., #hateisavirus) keywords. From this initial data set, we extracted a random subset of 1,000 Twitter users who had used one or more anti-Asian or counter-hate keywords. For each of these users, we calculated the total number of anti-Asian and counter-hate keywords posted each month. Latent growth curve analysis revealed that the frequency of anti-Asian keywords fluctuated over time in a curvilinear pattern, increasing steadily in the early months and then decreasing in the later months of our data collection. In contrast, the frequency of counter-hate keywords remained low for several months and then increased in a linear manner. Significant between-user variability in both anti-Asian and counter-hate content was observed, highlighting individual differences in the generation of hate and counter-hate messages within our sample. Together, these findings begin to shed light on longitudinal patterns of hate and counter-hate on social media during the COVID-19 pandemic.

Kaposiform hemangioendothelioma of skull base with dura invasion in a pediatric patient: a case report.

Kaposiform hemangioendothelioma is an extremely rare vascular tumor which shows aggressive local growth. We present a case of rapid growing vascular skull tumor with dura invasion in a pediatric patient with neurofibromatosis type 1. A 14-year-old male complained of headache and dizziness for 1 month after minor head trauma. Brain magnetic resonance imaging (MRI) revealed a 5-cm-sized tumor in the left frontotemporal bone with internal hemorrhage and cystic changes. The gross total resection of tumor was done. At the 7-month follow-up, brain MRI revealed a recurrent skull tumor with intracranial dura mass. He underwent second surgery, and the pathologic diagnosis was suggestive of Kaposiform hemangioendothelioma. For this vascular proliferative tumor, mTOR inhibitor was treated for 6 months, and there was the recurred nodular-enhancing mass along the sphenoid ridge. After additional 2 months of medication, the following MRI revealed a decreased nodular-enhancing mass.

Association between the Dietary Phytochemical Index and Lower Prevalence of Obesity in Korean Preschoolers.

Little is known regarding Korean preschooler dietary phytochemical index (DPIs). We used the 24 h recall data of 1196 participants aged 3-5 years from the Korea National Health and Nutrition Examination Survey to study the association between dietary food intake and obesity prevalence. The amount of dietary intake by food group was compared according to sex and DPI quartile. Multivariable-adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using logistic regression models. The average total DPI and energy from phytochemical food groups were not significantly different according to sex, although boys had a higher total daily food intake. Different inclinations between DPI quartiles and amount of intake were observed in the food groups; specifically, beans showed a higher intake difference between Q1 and Q4 for boys than in the other food groups. The highest DPI quartile had a significantly lower obesity prevalence than the lowest DPI quartile in all models for boys only when obesity prevalence by weight percentile was analyzed (Model 3, OR: 0.287, 95% CI: 0.095-0.868, p for trend < 0.05). Our results suggest a high DPI could help prevent obesity in preschoolers.

Comparative study of deep learning algorithms for atomic force microscopy image denoising.

Atomic force microscopy (AFM) enables direct visualisation of surface topography at the nanoscale. However, post-processing is generally required to obtain accurate, precise, and reliable AFM images owing to the presence of image artefacts. In this study, we compared and analysed state-of-the-art deep learning models, namely MPRNet, HINet, Uformer, and Restormer, with respect to denoising AFM images containing four types of noise. Specifically, these algorithms' denoising performance and inference time on AFM images were compared with those of conventional methods and previous studies. Through a comparative analysis, we found that the most efficient and the most effective models were Restormer and HINet, respectively. The code, models, and data used in this work are available at https://github.com/hoichanjung/AFM_Image_Denoising.

A Surgeon's Empirical Perspectives on Use of High-resolution Ultrasound in Preoperatively Detecting a Rupture in the Context of Breast Implant Crisis in Korea.

BACKGROUND: We previously proposed a novel method for detecting a rupture of a breast implant using high-resolution ultrasound (HRUS). We therefore conducted this retrospective, observational study to describe its feasibility in making a preoperative diagnosis of rupture of the device in patients receiving an implant-based augmentation mammaplasty. METHODS: We initially evaluated the medical records of the patients who had received primary or secondary augmentation mammaplasty using a breast implant at other hospitals for aesthetic or reconstructive purposes between August 31, 2017, and August 31, 2020. The patients underwent breast US using the Aplio i600 (Canon Medical System, Otawara, Tochigi, Japan) system with a 7-18 MHz linear transducer. Through a retrospective review of the patients' medical records, we analyzed their baseline and clinical characteristics. Then, we compared an agreement between preoperative diagnosis of rupture on HRUS and findings at reoperation. RESULTS: A total of 29 patients with rupture (55 breasts) were evaluated for the performance of ultrasound in making a diagnosis of rupture. This showed that they were unaware of rupture but they were diagnosed with it on ultrasound. Preoperatively, there were no cases of rupture in 110 left breasts (80.9%) and 107 right breasts (78.7%), which exactly matched to the number of breasts without rupture on HRUS. Moreover, preoperatively, there were 26 (19.1%) and 29 cases (21.3%) of rupture in the left and right breast, respectively, which exactly matched to the number of breasts with rupture on HRUS. CONCLUSIONS: In conclusion, patients who are suspected of having rupture of a breast implant should be stringently evaluated for presence of rupture and, if any, its scope using HRUS. Moreover, we propose that surgeons consider using HRUS in making a preoperative diagnosis of rupture of a breast implant.

Bleeding of the Superior Vena Cava Due to an Iatrogenic Injury to It during the Ultrasound-Guided Central Venous Cannulation.

Central venous cannulation (CVC) is a procedure that is frequently performed to facilitate resuscitation, nutritional support and long-term vascular access. It may often cause mechanical complications during placement of a cannula in association with the anatomical relationship with central veins. A 68-year-old man visited our medical institution with a chief complaint of foreign-body-induced esophageal perforation. This patient presented with bleeding of the superior vena cava due to an iatrogenic injury to it during the CVC in the right internal jugular vein. Our case indicates that it would be mandatory to insert a cannula at an optimal depth considering the anatomical relationship between the central veins during the CVC.

Development of a direction-sensitive gamma-ray monitoring system using a gamma camera with a dual-sided collimator: A Monte Carlo study.

Nuclear explosions, sabotage, and dirty bomb materials are considered a security threat. This paper discusses the development of a gamma-ray monitoring system that enables the screening of nuclear materials moving simultaneously on both sides of the system at ports. This direction-sensitive gamma-ray monitoring (DSGM) system consists of a monolithic plastic scintillator surrounded by 28 photomultiplier tubes and dual-sided parallel-hole lead collimators. With Monte Carlo simulation, the monitoring performance of the DSGM system was assessed for static and moving sources. A multilayer perceptron model was employed to estimate the energy-deposited position of the gamma-rays emitted by nuclear materials in the scintillator.

Seasonal Changes in Vitamin D Levels of Healthy Children in Mid-Latitude, Asian Urban Area.

PURPOSE: This study aimed to investigate the seasonal changes in vitamin D levels in a healthy pediatric population living in mid-latitude East Asian urban areas. METHODS: A pediatric population was selected from single secondary hospital visitors. Clinical data and serum vitamin D levels were collected retrospectively. Statistical analyses were performed based on the month of the blood sampling date, subject age, and vitamin D supplementation history. The data were categorized into three subgroups based on serum vitamin D levels-adequate (≥30 ng/mL), insufficient (20-29 ng/mL), and deficient (<20 ng/mL). RESULTS: Of the 481 patients, 172 had vitamin D supplementation history. More than 70% of the total study population had inadequate vitamin D levels (<30 ng/mL). The non-supplemented group and the supplemented group showed significantly uneven monthly distribution of the adequate, insufficient, and deficient subgroups. Only the non-supplemented group showed significantly different average vitamin D levels in the summer months compared to the winter months. In the non-supplemented group, vitamin D levels were the lowest in March, the highest in August and September. Significant relevance was noted between vitamin D supplementation status and vitamin D serum level in February and March. There was no significant difference between different age groups in terms of the distribution of vitamin D levels. CONCLUSION: Currently-widespread vitamin D replacement methods seem to have some effect on increasing the overall serum vitamin D levels, specifically during late winter when natural serum vitamin D levels plunge. However, they are unable to fully compensate the seasonal fluctuation.

Metabolic and Lipidomic Profiling of Vegetable Juices Fermented with Various Probiotics.

Fermented vegetable juices have gained attention due to their various beneficial effects on human health. In this study, we employed gas chromatography-mass spectrometry, direct infusion-mass spectrometry, and liquid chromatography-mass spectrometry to identify useful metabolites, lipids, and carotenoids in vegetable juice (VJ) fermented with Lactobacillus plantarum HY7712, Lactobacillus plantarum HY7715, Lactobacillus helveticus HY7801, and Bifidobacterium animalis ssp. lactis HY8002. A total of 41 metabolites, 24 lipids, and 4 carotenoids were detected in the fermented and non-fermented VJ (control). The lycopene, α-carotene, and ß-carotene levels were higher in VJ fermented with L. plantarum strains (HY7712 and HY7715) than in the control. Proline content was also elevated in VJ fermented with HY7715. Uracil, succinic acid, and α-carotene concentration was increased in VJ fermented with HY7801, while glycine and lycopene levels were raised in VJ fermented with HY8002. This study confirmed that each probiotic strain has distinctive characteristics and produces unique changes to metabolic profiles of VJ during fermentation. Our results suggest that probiotic-fermented VJ is a promising functional beverage that contains more beneficial metabolites and carotenoids than commercial non-fermented VJ.

Patients help other patients: Qualitative study on a longstanding community cooperative to tackle leprosy in India.

BACKGROUND: Although leprosy is portrayed as a disappearing disease, leprosy affected persons in India are still suffering massively. Even further, nearly 60% of the world's newly detected cases are appearing from India alone. The problem has exacerbated due to the drastic decrease of global funding after India's official declaration of 'elimination', which did not foster the actual pain of patients beyond prevalence. Leprosy patients have hardships in their lives due to disabilities, stigma and poverty; thus, they require sustained, continuous care even after release from treatment. Yet, current interventions mostly have a vertical, short-term approach, not showing much progress in lightening the burden of leprosy. In contrast, Little Flower Hospital Community (LFHC) in India has been remarkably providing holistic care for thousands of leprosy patients for 35 years. However, there has not been any research conducted to uncover the underlying factors of this longstanding leprosy control model. Therefore, this research explores the in-depth contextual attributes of this hospital community that has been able to successfully provide sustainable care for a long time even without excessive external funds. METHODS AND FINDINGS: This qualitative research used a grounded theory approach, involving 28 in-depth interviews of 11 patients, 13 workers, and 4 board members from the hospital. The interview data were inductively analyzed to examine the contextual factors of the hospital's sustainability. Open coding, axial coding and selective coding were conducted, and Glaser's Six C's model was used to create a theoretical model of the sustainability of LFHC. The fundamental cause of the sustainability was the leprosy patients' strong craving for life with dignity, despite the isolation from the society. The desire resulted in a bottom-up formation of a 'consumer-provider cooperative', where patients mutually support each other with basic treatment learned from experience. The profits earned from the patients' occupational efforts such as dairy farming, cover the costs needed to manage the hospital community, which contributes to economical sustainability. Social sustainability was established through the holistic care including psychosocial, educational, medical, and residential support. The wholesome care socially rehabilitated the patients to be included in the society with satisfaction, social justice and social cohesion. The main limitation of this study is that this study cannot be generalized due to the nature of Grounded Theory based study. CONCLUSIONS: This study investigated the determinants that made LFHC sustainable, and the findings suggested the importance of forming a cooperative community and implementing social rehabilitation for sustainable leprosy control. More exploration on transferring this model to other leprosy colonies will have great impact in maintaining sustainable care for leprosy patients. Furthermore, this research may highlight the importance of sustainable development in policies targeting neglected tropical diseases beyond leprosy as well.

Current Measurement Transducer Based on Current-to-Voltage-to-Frequency Converting Ring Oscillator with Cascade Bias Circuit.

We propose a ring oscillator (RO) based current-to-voltage-to-frequency (I-V-F) converting current transducer with a cascade bias circuit. The I-V-F converting scheme guarantees highly stable biasing against RO, with a rail-to-rail output operation. This device was fabricated using National NanoFab Center (NNFC) 180 nm complementary metal-oxide-semiconductor (CMOS) technology, which achieves a current resolution of 1 nA in a measurement range up to 200 nA. A noise floor of 11.8 pA/√Hz, maximum differential nonlinearity (DNL) of 0.15 in 1 nA steps, and rail-to-rail output with a 1.8 V power supply is achieved. The proposed transducer can be effectively applied to bio-sensing devices requiring a compact area and low power consumption with a low current output. The fabricated structure can be applied to monolithic-three-dimensional integration with a bio-sensing device.

Intravitreal Anti-Vascular Endothelial Growth Factor Treatment for Pachychoroid Neovasculopathy.

PURPOSE: To compare the effectiveness of intravitreal anti-vascular endothelial growth factor (anti-VEGF) treatment for pachychoroid neovasculopathy and neovascular age-related macular degeneration (AMD). METHODS: Twenty-two eyes with pachychoroid neovasculopathy and 183 eyes with neovascular AMD were retrospectively included for analysis. All patients were treatment naive and received an initial series of 3 monthly loading injections of anti-VEGF, followed by further injections as required. The visual and anatomical outcomes after treatment were evaluated at 12 months from baseline. RESULTS: The pachychoroid neovasculopathy group showed a significant improvement in the mean best-corrected visual acuity (BCVA; logarithm of the minimum angle of resolution) from 0.50 ± 0.32 (Snellen equivalent; 20/63) to 0.31 ± 0.28 (20/85, P = 0.021), and a decrease in the mean central foveal thickness from 373 ± 184 µm to 195 ± 137 µm at 12 months (P < 0.001). No significant intergroup difference in the achieved improvement of BCVA and decrease of central foveal thickness was observed. However, compared with the neovascular AMD group, the pachychoroid neovasculopathy group showed lower proportions of patients requiring retreatment during the maintenance phase (59.1% vs. 80.9%, P = 0.018), longer treatment-free period after loading injections (6.1 vs. 4.3 months, P = 0.006), and fewer number of injections (4.2 vs. 4.9, P = 0.031). CONCLUSIONS: Anti-VEGF treatment for pachychoroid neovasculopathy showed a similar efficacy to anti-VEGF treatment for neovascular AMD in improving visual acuity during 12 months. However, eyes with pachychoroid neovasculopathy had a significantly lesser need for retreatment during the maintenance phase and longer retreatment-free period, while requiring fewer injections.

Evaluation of the structural, physicochemical, and biological characteristics of SB4, a biosimilar of etanercept.

A biosimilar is a biological medicinal product that is comparable to a reference medicinal product in terms of quality, safety, and efficacy. SB4 was developed as a biosimilar to Enbrel® (etanercept) and was approved as Benepali®, the first biosimilar of etanercept licensed in the European Union (EU). The quality assessment of SB4 was performed in accordance with the ICH comparability guideline and the biosimilar guidelines of the European Medicines Agency and Food and Drug Administration. Extensive structural, physicochemical, and biological testing was performed with state-of-the-art technologies during a side-by-side comparison of the products. Similarity of critical quality attributes (CQAs) was evaluated on the basis of tolerance intervals established from quality data obtained from more than 60 lots of EU-sourced and US-sourced etanercept. Additional quality assessment was focused on a detailed investigation of immunogenicity-related quality attributes, including hydrophobic variants, high-molecular-weight (HMW) species, N-glycolylneuraminic acid (NGNA), and α-1,3-galactose. This comprehensive characterization study demonstrated that SB4 is highly similar to the reference product, Enbrel®, in structural, physicochemical, and biological quality attributes. In addition, the levels of potential immunogenicity-related quality attributes of SB4 such as hydrophobic variants, HMW aggregates, and α-1,3-galactose were less than those of the reference product.

[Conclusion] According to the results of this study, Kinesio taping of the ankle is effective for the prevention of ankle sprain.

Extremely Large Gate Modulation in Vertical Graphene/WSe2 Heterojunction Barristor Based on a Novel Transport Mechanism.

A WSe2 -based vertical graphene-transition metal dichalcogenide heterojunction barristor shows an unprecedented on-current increase with decreasing temperature and an extremely high on/off-current ratio of 5 × 10(7) at 180 K (3 × 10(4) at room temperature). These features originate from a trap-assisted tunneling process involving WSe2 defect states aligned near the graphene Dirac point.
