BACKGROUND: Pyroptosis is a type of programmed cell death mediated by the gasdermin family. Gasdermin B (GSDMB), as a member of gasdermin family, can promote the occurrence of cell pyroptosis. However, the correlations of the GSDMB expression in colorectal cancer with clinicopathological predictors, immune microenvironment, and prognosis are unclear.
METHODS: Specimens from 267 colorectal cancer cases were analyzed by immunohistochemistry to determine GSDMB expression, CD3+, CD4+, and CD8+ T lymphocytes, CD20+ B lymphocytes, CD68+ macrophages, and S100A8+ immune cells. GSDMB expression in cancer cells was scored in the membrane, cytoplasm, and nucleus respectively. GSDMB+ immune cell density was calculated. Univariate and multivariate survival analyses were performed. The association of GSDMB expression with other clinicopathological variables and immune cells were also analyzed. Double immunofluorescence was used to identify the nature of GSDMB+ immune cells. Cytotoxicity assays and sensitivity assays were performed to detect the sensitivity of cells to 5-fluorouracil.
RESULTS: Multivariate survival analysis showed that cytoplasmic GSDMB expression was an independent favorable prognostic indicator. Patients with positive cytoplasmic or nuclear GSDMB expression would benefit from 5-fluorouracil based chemotherapy. The assays in vitro showed that high GSDMB expression enhanced the sensitivity of colorectal cancer cells to 5-fluorouracil. Patients with positive membranous or nuclear GSDMB expression had more abundant S100A8+ immune cells in the tumor invasive front. Positive nuclear GSDMB expression indicated more CD68+ macrophages in the tumor microenvironment. Moreover, GSDMB+ immune cell density in the stroma was associated with a higher neutrophil percentage but a lower lymphocyte counts and monocyte percentage in peripheral blood. Furthermore, the results of double immunofluorescence showed that GSDMB co-expressed with CD68 or S100A8 in stroma cells.
CONCLUSION: The GSDMB staining patterns are linked to its role in cancer progression, the immune microenvironment, systemic inflammatory response, chemotherapeutic efficacy, and prognosis. Colorectal cancer cells with high GSDMB expression are more sensitive to 5-fluorouracil. However, GSDMB expression in immune cells has different effects on cancer progression from that in cancer cells.
The reported donor site morbidity of the fibula free flap (FFF) is low; however, several uncommon complications have been reported with tibia fracture rarely being reported. We present a case of a pathological tibial fracture in the setting of chronic osteomyelitis after FFF. A 54-year-old female presented with a benign fibro-osseous lesion of the right mandible and was treated with mandibulectomy and reconstructed with a left FFF. Approximately 1 year following surgery, the patient presented to the emergency department. Imaging showed a pathological fracture of the distal third of the tibial shaft with persistent erythema and cellulitis of the lateral prior graft harvest site without signs of systemic infection. She was taken to the operating room for irrigation and debridement with culture and biopsy as well as external fixation of the tibial fracture. Intraoperative biopsy and culture demonstrated fracture site change with callus formation and negative culture. The patient was discharged on 6 weeks of IV vancomycin and ceftriaxone. In conclusion, tibial fracture following FFF is an uncommon complication, yet it can be exacerbated by chronic osteomyelitis. This report highlights the importance of close observation and comprehensive wound care of donor sites after free flap harvest for head and neck reconstruction.
Aphantasia refers to reduced or absent visual imagery. While most of us can readily recall decade-old personal experiences (autobiographical memories, AM) with vivid mental images, there is a dearth of information about whether the loss of visual imagery in aphantasics affects their AM retrieval. The hippocampus is thought to be a crucial hub in a brain-wide network underlying AM. One important question is whether this network, especially the connectivity of the hippocampus, is altered in aphantasia. In the current study, we tested 14 congenital aphantasics and 16 demographically matched controls in an AM fMRI task to investigate how key brain regions (i.e. hippocampus and visual-perceptual cortices) interact with each other during AM re-experiencing. All participants were interviewed regarding their autobiographical memory to examine their episodic and semantic recall of specific events. Aphantasics reported more difficulties in recalling AM, were less confident about their memories, and described less internal and emotional details than controls. Neurally, aphantasics displayed decreased hippocampal and increased visual-perceptual cortex activation during AM retrieval compared to controls. In addition, controls showed strong negative functional connectivity between the hippocampus and the visual cortex during AM and resting-state functional connectivity between these two brain structures predicted better visualization skills. Our results indicate that visual mental imagery plays an important role in detail-rich vivid AM, and that this type of cognitive function is supported by the functional connection between the hippocampus and the visual-perceptual cortex.
Subjects will be enrolled for safety evaluation of MSC-IFNα monotherapy. Subjects will receive MSC-IFNα infusion from a dose of 2×10\^6 cells/kg 1-4 times every 4-6 weeks. All treatment-related adverse events(TRAE) will be recorded for at least 28 days after the cell infusion.
Patients on the treatment arm will take one tablet of crofelemer twice a day (each tablet is 125 mg), to be swallowed whole without chewing or crushing, during cycles 1-2 of chemotherapy with THP or TCHP. Patient will be monitored off crofelemer during cycle 3 of chemotherapy.
OBJECTIVE: Asthma is characterized by airway hyperresponsiveness due to chronic inflammation in the airways. One of the main cells involved in airway inflammation is eosinophils. In the current study, a bronchial provocation test (BPT) was performed to demonstrate airway hyperresponsiveness. We investigated the relationship between BPT and blood eosinophil count and the cut-off value of blood eosinophil count.
PATIENTS AND METHODS: In this study, we retrospectively evaluated the data of 246 patients who visited our immunology and allergy clinic, a tertiary reference center, with asthma symptoms between May 2017 and March 2020 and underwent BPT with methacholine for the diagnosis of asthma. The cases were grouped according to the level of BPT positivity and negativity.
RESULTS: Of 246 patients, BPT was positive in 90 (36.6%) and negative in 156 (63.4%). The blood eosinophil measurement of the BPT-positive cases was found to be statistically significantly higher than that of the BPT-negative cases (135 vs. 119 cells/µl, respectively, p=0.029). When BPT is grouped according to positivity levels, there was no statistically significant difference in blood eosinophil measurements between subgroups (p=0.174). As a result of the evaluations, the cut-off point obtained for the blood eosinophil count was determined as ≥226 cells/µl. For the blood eosinophil count, for the cut-off value of ≥226 cells/µl, sensitivity was 30.0%, specificity 87.7%, positive predictive value 58.7%, and negative predictive value 68.3%.
CONCLUSIONS: This study shows that BPT positivity is associated with blood eosinophil count. The cut-off value (≥226 cells/µl) determined for blood eosinophil count may be helpful when planning BPT and evaluating the diagnosis of asthma.
in which R2 is as defined herein with the proviso that when R2 of the second heptapeptide derivative is hydrogen then R3 of the first heptapeptide derivative is hydrogen or Boc-NH and when R2 of the second heptapeptide derivative is carboxyl then R3 of the first heptapeptide derivative is hydrogen. Said first and second heptapeptide derivatives are obtained from smaller peptides by a series of condensations involving the reaction of an appropriately protected peptide unit having an activated carboxylic ester with an appropriately protected peptide having a free amino group. Subsequently the first and second heptapeptide derivatives are condensed according to the azide method to obtain the linear tetradecapeptide derivative of formula   in which R2 and R3 are as defined herein; thereafter the linear tetradecapeptide derivative is transformed into the desired tetradecapeptide derivative of formula 1 by oxidizing and deprotecting processes. The linear, reduced form of the tetradecapeptides of this invention (i.e., the compounds of formula 1a) are obtained by deprotection of the aforementioned linear tetradecapeptide derivative or by reduction of the tetradecapeptide derivatives of formula 1. The compounds of formulae 1 and 1a are useful for management of juvenile diabetes and the treatment of acromegaly and methods for their use are disclosed.   Compounds of the formula 1 or 1a   IN WHICH R1 is hydrogen and R2 is hydrogen or carboxyl, or R1 is amino and R2 is hydrogen are disclosed.

This will be a single center, patient-blinded, randomized controlled trial. In the event that a patient does not meet inclusion criteria after signing the consent for and undergoing venogram/IVUS (screen fail), additional patients will be enrolled until 60 patients have been successfully randomized. Up to 80 patients will be consented in order to account for potential screen fails. Randomized patients will be followed monthly until their ulcer heals, every 3 months after healing for one year postoperatively.

Every patient subject will undergo venogram \& IVUS. The investigator experience with over 600 patients who underwent venous stenting at Mount Sinai - all of whom had preoperative MR venogram or CT venogram - revealed that pre-operative imaging missed the diagnosis of PVOO in approximately 10% of patients (this is unpublished data). Due to the small sample size of this pilot study, the very low risks associated with venogram and IVUS, and the 100% accuracy of venogram and IVUS in diagnosing PVOO, every study subject will undergo these two imaging studies. Once the diagnosis of PVOO is confirmed, the study subject will be immediately randomized in the OR. Study subjects randomized to convention therapy plus venous stents will undergo venous stent placement at the same sitting. For study subjects randomized to conventional therapy alone, the procedure will be terminated after venogram and IVUS.
BACKGROUND: Pulmonary hypertension (PH) is a progressive and fatal cardiopulmonary disease characterized by vascular remodeling and is associated with endothelial-to-mesenchymal transition (EndoMT). The pigment epithelium-derived factor (PEDF), a secretory protein widely distributed in multiple organs, has been shown to demonstrate anti-EndoMT activity in cardiovascular diseases. In the present study, the role of PEDF in PH was investigated.
METHODS: For PEDF overexpression, Sprague Dawley rats were infected with an adeno-associated virus through injection via the internal jugular vein. To establish PH models, the animals were subjected to monocrotaline or Sugen/hypoxia. Four weeks later, pulmonary artery angiography was performed, and hemodynamic parameters, right ventricular function, and vascular remodeling were evaluated. EndoMT and cell proliferation in the pulmonary arteries were assessed via immunofluorescence staining. Moreover, pulmonary artery endothelial cells (PAECs) isolated from experimental PH rats were cultured to investigate the underlying molecular mechanisms involved.
RESULTS: PEDF expression was significantly downregulated in PAECs from PH patients and PH model rats. Overexpressed PEDF alleviated the development of PH by improving pulmonary artery morphology and perfusion, reducing pulmonary artery pressure, improving right ventricular function, and alleviating vascular remodeling. PEDF inhibits EndoMT and reduces excessive PAEC proliferation. Moreover, PEDF overexpression reduced EndoMT in cultured PAECs by competitively inhibiting the binding of wnt to LRP6 and downregulating phosphorylation at the 1490 site of LRP6.
CONCLUSIONS: Our findings suggest that PEDF may be a potential therapeutic target for PH. We also found that PEDF can inhibit EndoMT in PAECs and may exert these effects by inhibiting the Wnt/LRP6/β-catenin pathway.

Sacroiliac(SI) joint pain can lead to long-lasting severe pain and reduce physical function. It is shown to be the source of pain in 13-30% of patients with low back pain. Former surgical techniques had a high level of complications and low success rates. Newer mini-invasive surgical approaches have shown promising results in scientific studies. It is difficult to find an adequate control group for surgery as most patients already have tried conservative and alternative treatments without effect. A sham-designed study is the best alternative. This study is designed as a prospective randomized double blinded controlled mulitcenter trial. The investigators want to examine whether there is a difference in SI joint pain in patients operated with miniinvasive arthrodesis of the SI joint compared to a sham operated control group. Patients with SI joint pain are included. They will be randomized to either surgery with arthrodesis or sham surgery. Neither patient nor health personell who work with the patient after the surgery will know what has been done. The primary end point for the study is group difference in sacroiliac joint pain on the operated side after 6 months.

Endometriosis (EM) is a gynecological inflammatory disease often accompanied by stress, chronic pelvic pain (CPP), anxiety, and depression, leading to a diminished quality of life. This review aims to discuss the relationship between systemic and local inflammatory responses in the central nervous system (CNS), focusing on glial dysfunctions (astrocytes and microglia) as in critical brain regions involved in emotion, cognition, pain processing, anxiety, and depression. The review presents that EM is connected to increased levels of pro-inflammatory cytokines in the circulation. Additionally, chronic stress and CPP as stressors may contribute to the dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis, depleting the production of inflammatory mediators in the circulatory system and the brain. The systemic cytokines cause blood-brain barrier (BBB) breakdown, activate microglia in the brain, and lead to neuroinflammation. Furthermore, CPP may induce neuronal morphological alterations in critical regions through central sensitization and the activation of glial cells. The activation of glial cells, particularly the polarization of microglia, leads to the activation of the NLRP3 inflammasome and the overproduction of inflammatory cytokines. These inflammatory cytokines interact with the signaling pathways involved in neural plasticity. Additionally, persistent inflammatory conditions in the brain lead to neuronal death, which is correlated with a reduced volume of key brain regions such as the hippocampus. This review highlights the involvement of glial cells in the pathogenesis of the mental comorbidities of EM (i.e., pain, anxiety, and depression) and to discuss potential therapeutic approaches for targeting the inflammation and activation of microglia in key brain regions.
BACKGROUND: Hip-preserving surgery in young patients frequently reveals lesions of the ligamentum teres (LT). Histological and clinical evidence supports that those lesions could be source of intraarticular hip pain. It has been hypothesized that LT degeneration could be linked to the abnormal positioning of the fovea outside the lunate surface during various daily motions. We introduce the "fossa-foveolar mismatch" (FFM) by determining the trajectory of the fovea in the fossa during hip motions, enabling a comparison across diverse hip-pathomorphologies.
AIMS: to determine (1) intraobserver reliability and (2) interobserver reproducibility of our computer-assisted 3-dimensional (3D) model of the FFM.
MATERIALS AND METHODS: All patients with joint preserving surgery for femoroacetabular impingement syndrome (FAIS) or developmental dysplasia of the hip (DDH) at our institution (11. 2015-08.2019)were initially eligible. We employed a simple random sampling technique to select 15 patients for analysis. Three-dimensional surface models based on preoperative computed tomography (CT) scans were built, the fossa virtually excised, the fovea capitis marked. Models were subjected to physiological range of motion with validated 3D collision detection software. Using a standardized medial view on the resected fossa and the transparent lunate surface, the FFM-index was calculated for 17 motions. It was obtained by dividing the surface occupied by the fovea outside of the fossa by the total foveolar tracking surface. Three observers independently performed all analyses twice. (1) Intraobserver reliability and (2) interobserver reproducibility were calculated using intraclass correlation coefficients (ICCs).
RESULTS: (1) We obtained excellent intraobserver ICCs for the FFM-index averaging 0.92 with 95% CI 0.77-0.9 among the three raters for all motions. (2) Interobserver reproducibility between raters was good to excellent, ranging from 0.76 to 0.98.
CONCLUSIONS: The FFM-index showed excellent intraobserver reliability and interobserver reproducibility for all motions. This innovative approach deepens our understanding of biomechanical implications, providing valuable insights for identifying patient populations at risk.
