Graded exercise with motion style acupuncture therapy for a patient with failed back surgery syndrome and major depressive disorder: a case report and literature review.

Effective treatment of failed back surgery syndrome (FBSS) remains challenging despite urgent medical attention requirements. Depression is a contributing factor to the development and poor prognosis of FBSS, and vice versa. We report the case of a patient with FBSS and major depressive disorder (MDD) treated with graded exercise combined with motion-style acupuncture therapy (MSAT). A 53-year-old male veteran who had undergone lumbar discectomy and laminectomy with instrumented fusion was admitted to the hospital with re-current back pain and radiative pain in the left leg. The effects of failed surgery triggered MDD as a comorbidity. After a six-week routine treatment without remarkable improvement, a three-week program of graded exercise with MSAT was applied. The numeric rating scale (NRS) and short form-36 (SF-36) were used to assess low back pain with radiating leg pain, and daily functioning levels, respectively. The voluntary walking distance of the patients was measured. To analyze the therapeutic effects and other applications of the intervention, we surveyed clinical trials using MSAT or graded exercise therapy (GET). Three weeks of graded exercise with MSAT reduced physical and mental functional disabilities (SF-36, physical component: 15.0 to 37.2, mental component: 21.9 to 30.1) as well as the intensity of low back pain and/or radiative leg pain (NRS: 50 to 30). Furthermore, as the therapeutic intensity gradually increased, there was a significant corresponding increase in daily walking distance (mean daily walking distance, the first week vs. baseline, second, and third week, 3.05 ± 0.56: 2.07 ± 0.79, 4.27 ± 0.96, and 4.72 ± 1.04 km, p = 0.04, p = 0.02, and p = 0.003, respectively). Three randomized controlled trials of GET were included, all showing statistically significant antidepressant effects in the diseased population. Graded exercise with MSAT may be an effective rehabilitative therapy for patients with FBSS and MDD who have impaired daily routines.

Development of cell-laden photopolymerized constructs with bioactive amorphous calcium magnesium phosphate for bone tissue regeneration via 3D bioprinting.

The synthesis of ideal bioceramics to guide the fate of cells and subsequent bone regeneration within the chemical, biological, and physical microenvironment is a challenging long-term task. This study developed amorphous calcium magnesium phosphate (ACMP) bioceramics via a simple co-precipitation method. The role of Mg2+ in the formation of ACMP is investigated using physicochemical and biological characterization at different Ca/Mg molar ratio of the initial reaction solution. Additionally, ACMP bioceramics show superior cytocompatibility and improved osteogenic differentiation of co-cultured MC3T3-E1 cells. Regulation of the microenvironment with Mg2+ can promote early-stage bone regeneration. For this, bioprinting technology is employed to prepare ACMP-modified 3D porous structures. Our hypothesis is that the incorporation of ACMP into methacrylated gelatin (GelMA) bioink can trigger the osteogenic differentiation of encapsulated preosteoblast and stimulate bone regeneration. The cell-laden ACMP composite structures display stable printability and superior cell viability and cell proliferation. Also, constructs loading the appropriate amount of ACMP bioceramic showed significant osteogenic differentiation activity compared to the pure GelMA. We demonstrate that the dissolved Mg2+ cation microenvironment in ACMP-modified composite constructs plays an effective biochemical role, and can regulate cell fate. Our results predict that GelMA/ACMP bioink has significant potential in patient-specific bone tissue regeneration.

Successful treatment of hemophagocytic lymphohistiocytosis in a patient with systemic lupus erythematosus with ruxolitinib: a case report.

Hemophagocytic lymphohistiocytosis (HLH) is a rare, life-threatening hematological disorder characterized by uncontrolled activation of CD8+ T and natural killer cells, leading to a cytokine storm and severe organ dysfunction. Although secondary HLH related to autoimmune diseases usually demonstrates a good treatment response to immunosuppressive therapy for underlying conditions, there is no consensus regarding the treatment in case of unresponsiveness to the treatment. Herein, we present a case of HLH that was unresponsive to high-dose glucocorticoid and cyclosporine treatment in a patient with newly diagnosed systemic lupus erythematosus. The patient's clinical features and laboratory abnormalities rapidly improved with ruxolitinib, an oral Janus kinase 1 and 2 (JAK1/2) inhibitor. This result suggests that blocking JAK-STAT pathway may be a potential treatment option in patients with refractory HLH secondary to autoimmune diseases.

Distinctive profile of monomeric and polymeric anti-SSA/Ro52 immunoglobulin A1 isoforms in saliva of patients with primary Sjögren's syndrome and Sicca.

OBJECTIVE: Primary Sjögren's syndrome (pSS) is the second most common chronic autoimmune connective tissue disease. Autoantibodies, immunoglobulin (IgG) anti-SSA/Ro, in serum is a key diagnostic feature of pSS. Since pSS is a disease of the salivary gland, we investigated anti-SSA/Ro52 in saliva. METHODS: Using a novel electrochemical detection platform, Electric Field-Induced Release and Measurement, we measured IgG/M/A, IgG, IgA, IgA isotypes (IgA1 and IgA2) and IgA1 subclasses (polymeric and monomeric IgA1) to anti-SSA/Ro52 in saliva supernatant of 34 pSS, 35 dry eyes and dry mouth (patients with Sicca) and 41 health controls. RESULTS: Saliva IgG/M/A, IgG, IgA, IgA isotypes and IgA1 subclasses to anti-SSA/Ro52 differed significantly between pSS, non-pSS Sicca and healthy subjects. Elevated monomeric IgA1 was observed in patients with non-pSS Sicca while elevated polymeric IgA1 (pIgA1) was observed in patients with pSS. Salivary polymeric but not monomeric IgA1 (mIgA1) isoform correlated with focus score (r2=0.467, p=0.001) CONCLUSIONS: Salivary anti-Ro52 polymeric IgA1 isoform is associated with glandular inflammation in pSS, while salivary monomeric IgA1 is associated with Sicca. Whether IgA1 isotope switching plays a role in the progression of the Sicca to pSS warrants further investigation.

Survey on the current usage of ultrasound-guided procedures in Korean Medicine Clinics and Hospitals.

Ultrasound-guidance is applied during the administration of Korean medicine (KM) interventions to improve the safety and effectiveness of the interventions. Although many case series and reports on the use of ultrasound-guided KM interventions have been reported, no study has investigated the current use of ultrasound-guidance in clinical practice by doctors of Korean medicine (KMDs). An online survey was conducted with questions examining the status of ultrasound-guidance usage among KMDs practicing in various KM clinical settings. Survey responses from 335 KMDs were collected. Ultrasound started to be widely used in the clinical practice of KM since 2022. The primary objective of using ultrasound-guidance was "To improve the accuracy and efficacy" by 54.6%. Ultrasound-guidance was most frequently applied for shoulder joint diseases, and pharmacopuncture was the most frequently used intervention (76.1% and 90.4%, respectively). The respondents reported that effectiveness could be enhanced the most in nerve entrapment syndromes and especially when used in shoulder joints. Over 90% of KMDs responded that the safety and efficacy of treatment, specialty, and patients' satisfaction were improved after adopting ultrasound-guidance. Moreover, 94.9% of KMDs agreed with the necessity for reimbursement of ultrasound-guidance in KM under national health insurance coverage. Most KMDs responded that they had positive perceptions regarding the clinical use of ultrasound-guidance in KM in terms of treatment effects, safety, and patient satisfaction, and the need for national health insurance coverage of the service. Our findings may provide practice-based evidence for conducting clinical studies.

Eucalyptus globulus leaf-isolated isorhapontin serves as a natural insecticide via acetylcholinesterase inhibition.

Acetylcholinesterase (AChE) inhibitors cause insect death by preventing the hydrolysis of the neurotransmitter acetylcholine, which overstimulates the nervous system. In this study, isorhapontin, isolated from E. globulus leaves, was evaluated as a natural insecticide with AChE inhibition at 12.5 µM. Using kinetic analyses, we found that isorhapontin acted as a competitive inhibitor that binds to the active site of AChE. The inhibition constant (Ki) was 6.1 µM. Furthermore, isorhapontin and resveratrol, which have basic skeletons, were predicted to bind to the active site of AChE via molecular docking. A comparison of the hydrogen bonding between the two stilbenes revealed characteristic differences in their interactions with amino acids. In isorhapontin, Trp83, Gly149, Tyr162, Tyr324, and Tyr370 interacted with the sugar moiety. These results suggest that with further development, isorhapontin can be used as an insecticide alternative.

Modulus-tunable multifunctional hydrogel ink with nanofillers for 3D-Printed soft electronics.

Seamless integration and conformal contact of soft electronics with tissue surfaces have emerged as major challenges in realizing accurate monitoring of biological signals. However, the mechanical mismatch between the electronics and biological tissues impedes the conformal interfacing between them. Attempts have been made to utilize soft hydrogels as the bioelectronic materials to realize tissue-comfortable bioelectronics. However, hydrogels have several limitations in terms of their electrical and mechanical properties. In this study, we present the development of a 3D-printable modulus-tunable hydrogel with multiple functionalities. The hydrogel has a cross-linked double network, which greatly improves its mechanical properties. Functional fillers such as XLG or functionalized carbon nanotubes (fCNT) can be incorporated into the hydrogel to provide tunable mechanics (Young's modulus of 10-300 kPa) and electrical conductivity (electrical conductivity of ∼20 S/m). The developed hydrogel exhibits stretchability (∼1000% strain), self-healing ability (within 5 min), toughness (400-731 kJ/m3) viscoelasticity, tissue conformability, and biocompatibility. Upon examining the rheological properties in the modulated region, hydrogels can be 3D printed to customize the shape and design of the bioelectronics. These hydrogels can be fabricated into ring-shaped strain sensors for wearable sensor applications.

Flare prediction after tapering the dose of tumour necrosis factor inhibitors in patients with axial spondyloarthritis: A nationwide cohort study.

OBJECTIVES: To develop a model for predicting flares after tapering the dose of tumour necrosis factor inhibitors (TNFi) in patients with axial spondyloarthritis (axSpA). METHODS: Data were obtained from the Korean College of Rheumatology Biologics and Targeted Therapy Registry. In total, 526 patients who received the standard-dose TNFi for at least 1 year and tapered their dose were included in the derivation cohort. The main outcome was a flare occurrence defined as an Ankylosing Spondylitis Disease Activity Score with C-reactive protein (ASDAS-CRP) score of ≥ 2.1 after 1 year of TNFi tapering. The final prediction model was validated using an independent cohort. RESULTS: Among 526 patients, 127 (24.1%) experienced flares. The final prediction model included negative human leucocyte antigen B27 (ß = 1.088), inflammatory back pain (ß = 1.072), psoriasis (ß = 1.567), family history of SpA (ß = 0.623), diabetes mellitus (ß = 1.092), TNFi tapering by ≥ 50% of the standard-dose (ß = 0.435), ASDAS-CRP at tapering (ß = 1.029), and Bath Ankylosing Spondylitis Functional Index score at tapering (ß = 0.194) as covariates. It showed an excellent discrimination performance (AUC = 0.828). According to the predictive risk, patients were classified into three groups (low-, intermediate-, and high-risk). The probabilities of flares in these groups were 4.5%, 18.1%, and 61.8%, respectively. The performance of the model in the validation cohort was also comparable. CONCLUSION: The established prediction model accurately predicted the risk of flares after TNFi dose tapering in patients with axSpA using eight simple clinical parameters, which could be helpful to select appropriate patients for tapering their TNFi without flare in daily clinical practice.

High-dose proton pump inhibitor treatment is associated with a higher mortality in cirrhotic patients: A multicentre study.

BACKGROUND: Proton pump inhibitors (PPI) are frequently used in patients with cirrhosis. AIMS: This study aimed to determine whether PPI use is associated with the prognosis of cirrhotic patients. METHODS: We conducted a multicentre retrospective cohort study involving 1485 patients who had experienced hepatic encephalopathy (HE) from 7 referral centres in Korea. The primary outcome was overall survival and secondary outcomes included the development of cirrhotic complications, including recurrent HE, spontaneous bacterial peritonitis (SBP), hepatorenal syndrome (HRS), and gastrointestinal bleeding. Patients treated with PPI with a mean defined daily dose (mDDD) ≥0.5 (high-dose PPI group) were compared to those treated with PPI of an mDDD < 0.5 (No or low-dose PPI group) for each outcome. RESULTS: Among 1485 patients (median age, 61 years; male, 61%), 232 were assigned to the high-dose PPI group. High-dose PPI use was independently associated with a higher risk of death (adjusted HR [aHR] = 1.71, 95% confidence interval [CI] = 1.38-2.11, p < 0.001). This result was reproducible after propensity score-matching (PSM) (aHR = 1.90, 95% CI = 1.49-2.44, p < 0.001). High-dose PPI use was an independent risk factor of recurrent HE (before PSM: aHR = 2.04, 95% CI = 1.66-2.51, p < 0.001; after PSM: aHR = 2.16, 95% CI = 1.70-2.74, p < 0.001), SBP (before PSM: aHR = 1.87, 95% CI = 1.43-2.43, p < 0.001; after PSM: aHR = 1.76, 95% CI = 1.31-2.36, p = 0.002), HRS (before PSM: aHR = 1.48, 95% CI = 1.02-2.15, p = 0.04; after PSM: aHR = 1.47, 95% CI = 0.95-2.28, p = 0.09), and gastrointestinal bleeding (before PSM: aHR = 1.46, 95% CI = 1.12-1.90, p = 0.006; after PSM: aHR = 1.74, 95% CI = 1.28-2.37, p < 0.001). CONCLUSIONS: The use of high-dose PPI was independently associated with increased risks of mortality and cirrhotic complications.

HTATIP2 Overexpression was Associated With a Good Prognosis in Gastric Cancer.

Introduction: The purpose of this study was to compare the transcriptomes of poorly cohesive carcinoma (PCC; diffuse-type) and well-differentiated tubular adenocarcinoma (WD; intestinal-type) using gastric cancer (GC) tissues and cell lines and to evaluate the prognostic role of HIV-1 Tat Interactive Protein 2 (HTATIP2). Materials and Methods: We performed next-generation sequencing with 8 GC surgical samples (5 WD and 3 PCC) and 3 GC cell lines (1 WD: MKN74, and 2 PCC: KATOIII and SNU601). Immunohistochemistry was used to validate HTATIP2 expression. We performed functional analysis by HTATIP2 overexpression (OE). Kaplan-Meier survival plots and the PrognoScan database were used for survival analysis. Results: The genes with significantly reduced expression in PCC versus WD (in both tissues and cell lines) were HTATIP2, ESRP1, GRHL2, ARHGEF16, CKAP2L, and ZNF724. According to immunohistochemical staining, the HTATIP2-OE group had significantly higher number of patients with early GC (EGC) (T1) (P = .024), less lymph node (LN) metastasis (P = .008), and low TNMA stage (P = .017) than HTATIP2 underexpression (UE) group. Better survival rates were confirmed in the HTATIP2 OE group by Kaplan-Meir survival and PrognoScan analysis. In vitro, HTATIP2-OE in KATO III cells caused a significant decrease in cancer cell migration and invasion. Decreased Snail and Slug expression in HTATIP2 OE cells suggested that epithelial-mesenchymal transition is involved in this process. Conclusion: HTATIP2 might be a good prognostic marker and a candidate target for GC treatment.

Electrocatalytic Activation in ReSe2-VSe2 Alloy Nanosheets to Boost Water-Splitting Hydrogen Evolution Reaction.

It is challenging to control the electronic structure of 2D transition metal dichalcogenides (TMD) for extended applications in renewable energy devices. Here, ReSe2-VSe2 (Re1- xVxSe2) alloy nanosheets over the whole composition range via a colloidal reaction is synthesized. Increasing x makes the nanosheets more metallic and induces a 1T″-to-1T phase transition at x = 0.5-0.6. Compared to the MoSe2-VSe2 and WSe2-VSe2 alloy nanosheets, ReSe2 and VSe2 are mixed more homogeneously at the atomic scale. The alloy nanosheets at x = 0.1-0.7 exhibit an enhanced electrocatalytic activity toward acidic hydrogen evolution reaction (HER). In situ X-ray absorption fine structure measurements reveal that alloying caused the Re and V atoms to be synergically more active in the HER. Gibbs free energy (ΔGH*) and density of state calculations confirm that alloying and Se vacancies effectively activate the metal sites toward HER. The composition dependence of HER performance is explained by homogenous atomic mixing with the increased Se vacancies. The study provides a strategy for designing new TMD alloy nanosheets with enhanced catalytic activity.

Modeling of antibody responses to COVID-19 vaccination in patients with rheumatoid arthritis.

To construct a model of the antibody response to COVID-19 vaccination in patients with rheumatoid arthritis (RA), and to identify clinical factors affecting the antibody response. A total of 779 serum samples were obtained from 550 COVID-19-naïve RA patients who were vaccinated against COVID-19. Antibody titers for the receptor binding domain (anti-RBD) and nucleocapsid (anti-N) were measured. The time from vaccination, and the log-transformed anti-RBD titer, were modeled using a fractional polynomial method. Clinical factors affecting antibody responses were analyzed by a regression model using generalized estimating equation. The anti-RBD titer peaked at about 2 weeks post-vaccination and decreased exponentially to 36.5% of the peak value after 2 months. Compared with the first vaccination, the 3rd or 4th vaccinations shifted the peaks of anti-RBD antibody response curves significantly upward (by 28-fold [4-195] and 32-fold [4-234], respectively). However, there was no significant shift in the peak from the 3rd vaccination to the 4th vaccination (p = 0.64). Multivariable analysis showed that sulfasalazine increased the vaccine response (by 1.49-fold [1.13-1.97]), but abatacept or JAK inhibitor decreased the vaccine response (by 0.13-fold [0.04-0.43] and 0.44-fold [0.26-0.74], respectively). Age was associated with lower ln [anti-RBD] values (coefficient: - 0.03 [- 0.04 to - 0.02]). In conclusion, the anti-RBD response of RA patients peaked at 2 weeks after COVID-19 vaccination, and then decreased exponentially, with the maximum peak increase observed after the 3rd vaccination. The antibody response was affected by age and the medications used to treat RA.

Interlayer Engineering and Prelithiation: Empowering Si Anodes for Low-Pressure-Operating All-Solid-State Batteries.

Silicon (Si) anodes, free from the dendritic growth concerns found in lithium (Li) metal anodes, offer a promising alternative for high-energy all-solid-state batteries (ASSBs). However, most advancements in Si anodes have been achieved under impractical high operating pressures, which can mask detrimental electrochemo-mechanical issues. Herein, we effectively address the challenges related to the low-pressure operation of Si anodes in ASSBs by introducing an silver (Ag) interlayer between the solid electrolyte layer (Li6 PS5 Cl) and anode and prelithiating the anodes. The Si composite electrodes, consisting of Si/polyvinylidene fluoride/carbon nanotubes, are optimized for suitable mechanical properties and electrical connectivity. Although the impact of the Ag interlayer is insignificant at an exceedingly high operating pressure of 70 MPa, it substantially enhances the interfacial contacts under a practical low operating pressure of 15 MPa. Thus, Ag-coated Si anodes outperform bare Si anodes (discharge capacity: 2430 vs 1560 mA h g-1 ). The robust interfacial contact is attributed to the deformable, adhesive properties and protective role of the in situ lithiated Ag interlayer, as evidenced by comprehensive ex situ analyses. Operando electrochemical pressiometry is used effectively to probe the strong interface for Ag-coated Si anodes. Furthermore, prelithiation through the thermal evaporation deposition of Li metal significantly improves the cycling performance.

2H-2M Phase Control of WSe2 Nanosheets by Se Enrichment Toward Enhanced Electrocatalytic Hydrogen Evolution Reaction.

The phase control of transition metal dichalcogenides (TMDs) is an intriguing approach for tuning the electronic structure toward extensive applications. In this study, WSe2 nanosheets synthesized via a colloidal reaction exhibit a phase conversion from semiconducting 2H to metallic 2M under Se-rich growth conditions (i.e., increasing the concentration of Se precursor or lowering the growth temperature). High-resolution scanning transmission electron microscopy images are used to identify the stacking sequence of the 2M phase, which is distinctive from that of the 1T' phase. First-principles calculations employing various Se-rich models (intercalation and substitution) indicated that Se enrichment induces conversion to the 2M phase. The 2M phase WSe2 nanosheets with the Se excess exhibited enhanced electrocatalytic performance in the hydrogen evolution reaction (HER). In situ X-ray absorption fine structure studies suggested that the excess Se atoms in the 2M phase WSe2 enhanced the HER catalytic activity, which is supported by the Gibbs free energy (ΔGH* ) of H adsorption and the Fermi abundance function. These results provide an appealing strategy for phase control of TMD catalysts.

Exploring the role of copine 1 in human colorectal cancer: investigating its association with tumorigenesis and metastasis.

Purpose: This study aimed to investigate the potential role of copine-1 (CPNE1), a calcium-dependent membrane-binding protein encoded by the CPNE1 gene, in colorectal cancer (CRC). Despite previous research on the involvement of copine family members in various solid tumors, the specific role of CPNE1 in CRC remains poorly understood. Methods: We conducted clinicopathological analysis and functional studies to explore the impact of CPNE1 in human CRC. We examined the expression levels of CPNE1 in CRC patients and correlated it with invasive depth, lymph node metastasis, distant metastasis, lymphatic invasion, and TNM stage. Additionally, we performed experiments to assess the functional consequences of CPNE1 knockdown in CRC cells, including proliferation, colony formation, migration, invasion, and the expression of key regulators involved in the cell cycle and epithelial-mesenchymal transition (EMT). Furthermore, we evaluated the effects of CPNE1 knockdown on tumor growth using a xenograft mouse model. Results: High expression of CPNE1 was significantly associated with advanced tumor features in CRC patients. CPNE1 knockdown in CRC cells led to impaired abilities in proliferation, colony formation, migration, and invasion. Furthermore, CPNE1 silencing resulted in the suppression of protein expression related to the cell cycle and EMT. In the xenograft mouse model, CPNE1 knockdown inhibited tumor growth. Conclusion: CPNE1 plays a crucial role in promoting tumorigenesis and metastasis in human CRC. By regulating the cell cycle and EMT, CPNE1 influences critical cellular processes at the membrane-cytoplasm interface. These results provide valuable insights into the potential development of novel therapeutic strategies for CRC targeting CPNE1.

COVID-19 infection and efficacy of vaccination in patients with rheumatic diseases during Omicron outbreak in South Korea: a prospective cohort study.

OBJECTIVES: This study aims to investigate COVID-19 epidemiological data in patients with autoimmune inflammatory rheumatic diseases (AIRDs) during Omicron wave and to identify clinical factors associated with infection, including COVID-19 vaccination. METHODS: This prospective longitudinal study was performed between January and October 2022 in South Korea. Patients were classified into AIRD and non-AIRD groups according to their underlying diseases. COVID-19 status, date of confirmed infection and vaccination status were captured from the patient survey and national database. The COVID-19 incidence during the study period was examined and compared between the two groups. The effect of clinical factors on the infection rate was analysed in the AIRD group. RESULTS: A total of 1814 patients (1535 and 279 in the AIRD and non-AIRD groups, respectively) were analysed. During the study period, 857 COVID-19 cases were reported in 834 patients (46.0%). The infection rates in the AIRD and non-AIRD groups were comparable. In the AIRD group, older age (≥70 years) and glucocorticoid use were significantly associated with a lower rate of COVID-19 infection. The third booster vaccination significantly lowered the incidence of COVID-19 (adjusted HR 0.85 (95% CI 0.73 to 0.99)), and the prophylactic effect was more evident in patients aged <70 years (0.81 (95% CI 0.69 to 0.95), p value for interaction 0.036). CONCLUSION: The risk of SARS-CoV-2 infection with the Omicron variant did not increase in patients with AIRDs. The third booster vaccination regimen decreased the infection rate in patients aged <70 years.

Effectiveness and Safety of Progressive Loading-Motion Style Acupuncture Treatment for Acute Low Back Pain after Traffic Accidents: A Randomized Controlled Trial.

BACKGROUND: Traffic injuries include acute low back pain (LBP) needing active treatment to prevent chronicity. This two-armed, parallel, assessor-blinded, randomized controlled trial evaluated the effectiveness and safety of progressive loading-motion style acupuncture treatment (PL-MSAT) for acute LBP following traffic accidents. METHODS: Based on an effect size of 1.03, 104 participants were recruited and divided in a 1:1 ratio into PL-MAST and control groups using block randomization. Both groups underwent integrative Korean medicine treatment (IKMT) daily; only the PL-MSAT group underwent three PL-MSAT sessions. The outcomes were assessed before and after the treatment sessions and at 1 and 3 months post-discharge. The primary outcome was the difference in the numeric rating scale (NRS) for LBP. The secondary outcomes included a visual analog scale for LBP, leg pain status, the Oswestry disability index, lumbar active range of motion (ROM), quality of life, Patient Global Impression of Change, and Post-Traumatic Stress Disorder Checklist adverse events. RESULTS: In the modified intention-to-treat analysis, 50 and 51 participants were included in the PL-MSAT and control groups. On Day 4, the mean LBP NRS score was 3.67 (3.44-3.90) in the PL-MSAT group, indicating a significantly lower NRS 0.77 (0.44-1.11) compared to 4.44 (4.20-4.68) for the control group (p < 0.001). The PL-MSAT group exhibited greater ROM flexion (-5.31; -8.15 to -2.48) and extension (-2.09; -3.39 to -0.80). No significant differences were found for the secondary outcomes and follow-ups. CONCLUSIONS: Compared with IKMT alone, PL-MSAT plus IKMT showed significantly better outcomes for reducing pain and increasing the ROM in acute LBP.

Lactobacillus helveticus Isolated from Raw Milk Improves Liver Function, Hepatic Steatosis, and Lipid Metabolism in Non-Alcoholic Fatty Liver Disease Mouse Model.

Here, we show that Lactiplantibacillus plantarum LP158 (LP158), Lactobacillus helveticus HY7804 (HY7804), and Lacticaseibacillus paracasei LPC226 (LPC226) isolated from raw milk alleviate non-alcoholic fatty acid disease (NAFLD) in a C57BL/6 mouse model. Lactic acid bacteria (LAB) were screened for their ability to inhibit fatty acid accumulation in palmitic acid (PA)-treated HepG2 cells, and three strains were selected based on the results. We also investigated hemolytic activity and antibiotic resistance of the three strains. LP158, HY7804, and LPC226 suppressed expression of mRNA encoding genes related to lipogenesis, and increased expression of genes related to ß-oxidation, in a PA-induced HepG2 cell model. Moreover, when LP158, HY7804, and LPC226 were administered at 109 CFU/kg/day for 8 weeks to mice with dietary-induced NAFLD, they all modulated blood biochemistry markers and reduced steatosis in liver tissue. Also, all three strains significantly reduced expression of mRNA encoding lipogenesis genes (Fasn, Acaca, and Srebp-1c) and inflammatory factors (Tnfα and Ccl-2) and fibrosis factors, and increased expression of a ß-oxidation gene (Acox1) in the liver. In particular, HY7804 showed the strongest effects both in vitro and in vivo. Therefore, HY7804, LP158, and LPC226 can be proposed as potential supplements that can improve NAFLD through anti-steatosis, anti-inflammatory, and anti-fibrotic effects.

An observational, prospective, open label, multicenter study to evaluate the safety and effectiveness of pegfilgrastim as secondary prophylaxis to decrease the incidence of febrile neutropenia in Korean female patients with breast cancer.

PURPOSE: Pegfilgrastim is a widely used long-acting granulocyte colony-stimulating factor (G-CSF) that prevents febrile neutropenia (FN) in patients with breast cancer receiving chemotherapy. This study aimed to evaluate the incidence of chemotherapy-related FN events and other adverse events (AEs) during chemotherapy in Korean patients with breast cancer treated with pegfilgrastim as secondary prophylactic support. MATERIALS AND METHODS: This was a multicenter, open-label, prospective, observational study. A total of 1255 patients were enrolled from 43 institutions. The incidence of FN was evaluated as the primary endpoint. The secondary endpoints included (1) incidence of bone pain, (2) proportion of patients with a relative dose intensity (RDI) of ≥85%, and (3) proportion of patients with AE. RESULTS: Pegfilgrastim administration reduced FN by 11.8-1.6%. The highest incidence of bone pain was observed at the time point of the 1st day after the administration and mild bone pain was the most common of all bone pain severity. The mean RDI was 98.5 ± 7.3%, and the proportion of the patients with and RDI≥85% was 96.9% (1169/1233). AEs were reported in 52.6% of the patients, and serious drug reactions occurred in only 0.7%. CONCLUSION: The use of pegfilgrastim as secondary prophylaxis was effective and safe for preventing FN in patients with breast cancer who were treated with chemotherapy.

Reliability and Validity of the Korean Version of the Gout Impact Scale.

BACKGROUND: The Gout Impact Scale (GIS), part of the Gout Assessment Questionnaire 2.0, measures gout-specific health-related quality of life (HRQOL). This study aimed to translate the GIS into Korean and validate the Korean version (K-GIS) using generic HRQOL measures. METHODS: The GIS was translated into Korean and back-translated into English. We asked patients aged 18 years or older who met the 2015 gout classification criteria to fill out the questionnaires (from January 2022 to June 2022); the K-GIS (5 scales [0-100 scores each]), along with the Korean version of Health Assessment Questionnaire (HAQ) and EuroQol-5 dimension (EQ-5D). We investigated the internal consistency, construct validity, and discriminative validity for gout characteristics of K-GIS. The K-GIS form was administrated to patients 4 weeks later to assess the test-retest reliability using the intraclass correlation coefficient (ICC). RESULTS: One hundred patients completed the questionnaire. The mean ± standard deviation age of the patients was 53.0 ± 15.1 years, and 99.0% of the patients were men. All scales had high degree of internal consistency (Cronbach's α = 0.59 to 0.96) and test-retest reliability (n = 18, ICC = 0.83 to 0.94, all P < 0.001), except for unmet gout treatment needs. Weak-to-moderate correlations were observed between the K-GIS scales and HAQ or EQ-5D (r = 0.21 to 0.46). The K-GIS scores were significantly higher in the presence of bone erosion, absence of urate-lowering therapy, serum urate levels > 6 mg/dL, frequent gout flares in the past year, and fewer comorbidities. In contrast, neither the HAQ nor the EQ-5D could discern these subsets of patients. CONCLUSION: The K-GIS is a reliable and valid HRQOL measure for patients with gout. Higher K-GIS scores were associated with clinical characteristics leading to unfavorable outcomes, which were not demonstrated by the HAQ and EQ-5D.
