This study aimed to evaluate the effect of bovine leukemia virus (BLV) on the systemic profile of naturally infected dairy heifers during the transition period. Pregnant Holstein and Jersey heifers (n=24) were distributed in pairs into two experimental groups: (BLV+) and (BLV–). Animals in the BLV+ group were divided into two subgroups based on the median BLV proviral load (high and low). The animals were then assessed at weeks –3, –2, –1, calving time (0), +1, +2, and +3. Blood samples were obtained for hematological and biochemical analyses, as well as haptoglobin measurements. Farm BLV screening revealed a herd BLV prevalence of 57.25% and heifer BLV prevalence of 38.7%. Mean corpuscular hemoglobin concentration was the only hematological variable for which group interaction was observed, with BLV+ cattle having higher values (33.29 ± 3.39%) than BLV– cattle (31.08 ± 2.31%). Aspartate aminotransferase activity was higher in the BLV+ heifers. The BLV+ group had greater incidence of inflammation (haptoglobin ≥ 2.0 mg/dL). Fibrinogen concentrations were also higher at weeks 0 and +1 in BLV+ heifers than in BLV– heifers. A high proviral load affected total leukocyte and lymphocyte count; however, this profile was not observed in the low proviral load and paired BLV– heifers. To our knowledge, this is the first study to report the impact of BLV infection on the health of dairy heifers during the transition period, demonstrating the effect of proviral load on white blood cell changes and early inflammation in infected animals.

Environmental changes associated with global warming create new opportunities for pathogen and parasite transmission in Arctic wildlife. As an apex predator ranging over large, remote areas, changes in pathogens and parasites in polar bears are a useful indicator of changing transmission dynamics in Arctic ecosystems. We examined prevalence and risk factors associated with exposure to parasites and viral and bacterial pathogens in Chukchi Sea polar bears. Serum antibodies to six pathogens were detected and prevalence increased between 1987–1994 and 2008–2017 for five: Toxoplasma gondii, Neospora caninum, Francisella tularensis, Brucella abortus/suis, and canine distemper virus. Although bears have increased summer land use, this behavior was not associated with increased exposure. Higher prevalence of F. tularensis, Coxiella burnetii, and B. abortus/suis antibodies in females compared to males, however, could be associated with terrestrial denning. Exposure was related to diet for several pathogens indicating increased exposure in the food web. Elevated white blood cell counts suggest a possible immune response to some pathogens. Given that polar bears face multiple stressors in association with climate change and are a subsistence food, further work is warranted to screen for signs of disease. [ABSTRACT FROM AUTHOR]

Objective: This study investigates the impact of transvascular antitumor interventional therapies on immune cell dynamics and its correlation with disease control and progression-free survival (PFS) in hepatocellular carcinoma (HCC) patients. Methods: A single-center observational case-control study was conducted with 119 HCC patients. Transvascular antitumor interventional therapy were administered based on patient-specific evaluations. Peripheral blood samples were collected before and within 28 days after the first treatment to analyze lymphocyte subsets and other immune cells. Results: Higher counts of total white blood cells (WBCs), lymphocytes, monocytes, and basophils were significantly associated with disease control rate. Subgroup analysis revealed that abnormal BMI, diabetes, infection, and multiple lesions were significantly associated with T cell abnormalities. Age, abnormal BMI, hypertension, and abnormal AFP were linked to total T cell abnormalities. NK cells, B cells, Th cells, Tc/Ts cells, and CD4/CD8 ratios did not show significant differences in PFS probabilities. Conclusion: Higher counts of WBCs, lymphocytes, monocytes, and basophils, play a crucial role in the effectiveness of HCC interventional therapy. [ABSTRACT FROM AUTHOR]

Objectives: Tracheobronchial Talaromyces marneffei (T. marneffei) infections among HIV-infected patients are rare. To improve understanding, we analyzed the clinical features, immune mechanisms, treatment, and prognosis of these patients. Methods: We collected clinical information from HIV-positive patients with talaromycosis admitted to the Fourth People's Hospital of Nanning from January 2015 to June 2022. Patients who presented with culture and/or histopathological proof of tracheobronchial T. marneffei infection were included. Results: A total of 108 patients with respiratory infections who underwent bronchoscopy were enrolled. Seven patients with tracheobronchial T. marneffei infection, all of whom were men with a median age of 48 years (range 39–50 years), were analyzed. Cough, sputum, fever, and weight loss were the most common symptoms. The total white blood cell count was normal or decreased, and all lymphocyte counts were decreased. All patients had reduced CD4+ T-cell counts, with values less than 50 cells/µL. The chest CT imaging signs included patchy signals or large areas of exudation, bronchial stenosis and occlusion. This was different from the lack of bronchial involvement. Endoscopically, the trachea and bronchial mucosa showed congestion, edema, surface attachment, nodules, lumen stenosis, obstruction, etc. T. marneffei spores were found via bronchial mucosal pathology in all 7 patients. Five patients were initially treated with intravenous infusion of amphotericin B for 2 weeks, followed by oral itraconazole capsules (200 mg) twice daily, and two patients were initially treated with itraconazole. Six patients were remission, and 1 died. Conclusions: The clinical features of trachea invasion and nontracheal invasion are not unique, but chest CT reveals manifestations such as masses, solid shadows, and bronchial stenosis/obstruction. Bronchoscopy should be performed if possible, and the presence or absence of trachea T. marneffei infection should be confirmed. Antiviral therapy combined with antifungal therapy can improve patient prognosis. [ABSTRACT FROM AUTHOR]

Background: Tuberculous meningitis (TBM) is a severe central nervous system (CNS) infection with a challenging diagnosis due to inadequate detection methods. This study evaluated current clinical detection methods and their applicability. Methods: A cohort of 514 CNS infection patients from 2018 to 2020 was studied. Data on general demographics, Cerebrospinal Fluid (CSF) analysis, epidemiology, and clinical outcomes were collected. TBM patients were identified, and the sensitivities of mmetagenomic next-generation sequencing (NGS), GeneXpert, and microbial culture were compared. Kappa statistic assessed the consistency between methods. Results: Among the patients involved, TBM (29%) and neurosyphilis (25%) were the two most prevalent CNS infections. CSF analysis indicated that 76% of patients had leukocytosis, suggesting a potential CNS inflammation. In TBM cases, 92.5% had elevated CSF protein and leukocyte counts. Moreover, the percentage of positive mNGS results was 55.6%. GeneXpert and MTB cultures alone had lower sensitivity, but combined use resulted in a 53.4% positive rate. Conclusions: This study highlights the high sensitivity of mNGS, comparable to GeneXpert and MTB culture. The combined methods are cost-effective and straightforward, and can partially substitute for mNGS, offering valuable alternatives for TBM diagnosis and providing insights into multiple diagnostic strategies in clinical practice.

Background: Dengue is the most re-emergent infection, with approximately 100 million new cases reported annually, yet no effective treatment or vaccine exists. Here, we aim to define the microbial community structure and their functional profiles in the dengue positive patients with varying disease severity. Methodology/Principal findings: Hospital admitted 112 dengue-positive patients blood samples were analyzed by dual RNA-sequencing to simultaneously identify the transcriptionally active microbes (TAMs), their expressed genes and associated pathways. Results highlight that patients with severe dengue exhibited increased microbial diversity and presence of opportunistic species (unique and core) which includes Bacillus cereus, Burkholderia pseudomallei, Streptococcus suis, and Serratia marcescens. The functional profile analysis revealed enriched metabolic pathways such as protein degradation, nucleotide biosynthesis, ion transport, cell shape integrity, and ATP formation in severe cases, indicating the high energy demands and adaptability of these microbes. Conclusion: Our metatranscriptomic approach provides a species-level characterization of blood microbiome composition and reveals a heightened diversity of TAMs in patients with severe dengue, underscoring the need for further research into the role of blood microbiota in disease progression. Comparing the microbial signatures across the severity classes early in the disease offers unique potential for convenient and early diagnosis of dengue infection. Author summary: Dengue poses a significant public health challenge in tropical and subtropical regions. The lack of a specific treatment or broadly effective vaccine highlights the critical need for novel approaches. In this study, we investigated the transcriptionally active microbial species (TAMs) in 112 dengue-positive patients from MAX Hospital in Delhi, India, to identify their correlations with disease severity. RNA-seq analysis revealed an increased abundance of opportunistic TAMs in severe dengue patients, with some species showing significant associations with platelet counts and total leukocyte count (TLC). Our findings underscore the underappreciated importance of the blood microbiome in dengue, particularly the heightened metabolic activity of these opportunistic species in severe cases. This study offers valuable insights for early infection diagnosis for dengue management. The species-level data identified here could pave the way for systematic exploration of microbial involvement in dengue virus (DENV) infections, potentially serving as an indicator for new adjuvant treatment strategies.

Background: Leukocytosis and thrombocytosis often follow splenectomy in blunt trauma patients, complicating the postoperative identification of infection. While the platelet count to white blood cell ratio provides diagnostic assistance to discern between expected laboratory alterations and infection, diagnoses such as leukemia are often overlooked. Case presentation: A 53-year-old Hispanic male presented with abdominal pain, nausea, tachycardia, and focal peritonitis 4 days after being assaulted and struck multiple times in the abdomen. Initial white blood cell count was 38.4 × 109/L, platelet count was 691 × 109/L, and lipase was 55 U/L. Computed tomography abdomen/pelvis demonstrated a hematoma encasing the distal pancreas and abutting the stomach and colon. Emergent laparotomy revealed a nearly transected pancreas and devascularized colon, necessitating a distal pancreatectomy, splenectomy, and colonic resection with primary anastomosis. Postoperatively, he had a persistently elevated leukocytosis, thrombocytosis, segmented neutrophils, eosinophilia, and basophilia (peak at 70, 2293, 64, 1.1, and 1.2 × 109/L, respectively). Despite sepsis workup, including repeat computed tomography, no source was identified. Hematology/oncology was consulted for concern for hematologic etiology, with genetic testing and bone marrow biopsy performed. The diagnosis of breakpoint cluster–Abelson gene-positive chronic myeloid leukemia was made based on genetic tests, including polymerase chain reaction and fluorescence in situ hybridization analysis, which confirmed the presence of the Philadelphia chromosome. Bone marrow biopsy suggested a chronic phase. The patient was treated with hydroxyurea and transitioned to imatinib. Conclusions: Thrombocytosis following splenectomy is a common complication and a plate count to white blood cell count ratio < 20 indicates infectious etiology. A significantly elevated white blood cell count (> 50 × 109/L) and thrombocytosis (> 2000 × 109/L) may suggest something more ominous, including chronic myeloid leukemia , particularly when elevated granulocyte counts are present. Chronic myeloid leukemia workup includes peripheral smear, bone marrow aspiration, and determination of Philadelphia chromosome. Post-splenectomy vaccines are still indicated within 14 days; however, the timing of immunization with cancer treatment must be considered. Tyrosine kinase inhibitors are the first-line therapy and benefits of pretreatment with hydroxyurea for cytoreduction remain under investigation. Additionally, tyrosine kinase inhibitors have been associated with gastrointestinal perforation and impaired wound healing, necessitating heightened attention in patients with a new bowel anastomosis.

Background: We aimed to develop multiple machine learning models to predict the risk of early intracranial aneurysms (IAs) rupture, evaluate and compare the performance of predictive models. Methods: Information related to patients diagnosed with IA by CT angiography and clinicians in Central hospital of Dalian University of Technology from January 2010 to June 2022 was collected, including clinical characteristics, blood indicators and IA morphological parameters. IA with rupture or maximum growth ≥ 0.5 mm within 1 month of first diagnosis was considered unstable. The relevant factors affecting IA stability were screened and predictive models were developed based on the above three levels, including random forest (RF), support vector machine (SVM), and artificial neural network (ANN). Sensitivity, specificity, accuracy and area under curve (AUC) value were used to evaluate the predictive models. Results: A total of 989 IA patients were included in the study, including 561 stable patients and 428 unstable patients. For RF models, the training set showed that sensitivity, specificity, accuracy and the AUC values were 72.8–83.7%, 76.9–86.9%, 75.1–84.1% and 0.748 (0.719–0.778)–0.839 (0.814–0.864), respectively; after test set validation, the results were 71.9–78.8%, 75.0–84.0%, 73.6–81.1% and 0.734 (0.688–0.781)–0.809 (0.768–0.850), respectively. For SVM models, the training set were 66.0–80.2%, 76.5–85.5%, 71.7–82.3%, 0.712 (0.682–0.743)–0.913 (0.884–0.924), respectively; the test set were 44.2–78.3%, 63.4–84.4%, 57.9–80.9%, 0.699 (0.651–0.747)–0.806 (0.765–0.848), respectively. For ANN models, the training set were 66.8–83.0%, 75.3–82.3%, 71.6–82.1%, 0.783 (0.757–0.808)–0.897 (0.879–0.914); the test set were 63.1–76.3%, 65.5–84.0%, 64.4–80.6%, 0.680 (0.593–0.694)–0.860 (0.821–0.899). The results of variable importance showed that age, white blood cell count (WBC) and uric acid (UA) played an important role in predicting the stability of IA. Conclusions: The predictive stability models of IA based on three artificial intelligence methods shows good clinical application. Age, WBC and UA played an important role in predicting the IA stability, and were potentially important predictors. [ABSTRACT FROM AUTHOR]

Background/Objectives: Surgical removal of deep endometriosis lesions is an established method of reducing patient symptoms, but it often results in iatrogenic adhesions that lead to further problems. This pilot study presents the safety evaluation of a novel self-cross-linked hyaluronic acid gel used to reduce adhesions after non-bowel deep endometriosis surgery. Methods: A single cohort, single-center, non-randomized pilot study was conducted in patients diagnosed with non-bowel deep endometriosis who underwent a three-stage treatment regimen consisting of first surgery, hormone therapy and second surgery. The present report is limited to an analysis of the inflammatory parameters, pain and complications occurring within a 72 h period following the initial laparoscopy (FLL) utilizing the anti-adhesion gel. Results: 60 patients (28.48 ± 5.9 years old) were included. 24 h after the intervention, a slight elevation in C-reactive protein levels was observed in 38.33% of cases (0.98 ± 1.46 mg/dL), with a statistically significant difference after FLL (0.98 ± 1.46 mg/dL before FLL vs. 1.03 ± 1.29 mg/dL after FLL; p =< 0.001); there were no patients with levels above 10 mg/dL before or after surgery. 24 h after FLL, 29.33% of patients had a leukocyte count greater than 11 Thous/μL, with a maximum observed value of 16.2 Thous/μL. The count was found to be statistically significantly higher after FLL (6.03 ± 1.91 Thous/μL before FLL vs. 9.15 ± 2.61 Thous/μL after FLL; p =< 0.001). At 72 h post-intervention, postoperative pain was reported in up to 63.33% of cases, and one urinary tract infection with fever occurred but was not considered to be related to the product. No serious adverse events were observed. Conclusions: The results of this exploratory study showed a safe range of inflammatory response within a 24 h period following the application of the novel self-cross-linked hyaluronic acid antiadhesion gel (HyaRegen®) in patients who underwent laparoscopic surgery for non-bowel deep endometriosis.

Background/Objectives: Research on the effects of training on the health of amateur cross-country skiers remains limited, particularly on biochemical parameters. Therefore, this study aimed to assess such changes in response to four months of training for amateur cross-country skiers. Methods: Blood samples were collected after spring training in May (active rest) and in September at the end of the preparatory period. The Wilcoxon signed-rank test was used for comparison of both measurements (initial and final). Results: Training in a group of amateur cross-country skiers exerts a statistically significant influence on the decrease in leukocyte count (thousand/µL) (p = 0.045) and the decrease in mean corpuscular hemoglobin concentration (MCHC) (g/dL) (p = 0.021). The other parameters did not show statistically significant changes. Conclusions: The change in MCHC and WBC can be attributed to adaptation to prolonged exercise, with a simultaneous increase in VO2 max. It should not be identified with pathology. The decrease in MCHC was likely attributable to changes in hydration status and a slight reduction in hemoglobin concentration. Similarly, it is recommended that other biochemical parameters be within the reference ranges. [ABSTRACT FROM AUTHOR]

Biofloc technology offers a viable choice for the rearing of fish seed by offering a safe and protected habitat for young fish. Nevertheless, it is crucial to establish a standardised stocking density and implement effective ameliorative steps in order to successfully utilise this technology. In this study, a 90‐day investigation was conducted to assess the effect of stocking density and dietary vitamin C (Vit C) levels on the growth and immunity of Labeo gonius fry (1.03 ± 0.01 g) reared in a biofloc system. Three stocking density groups (5, 10 and 15 fish per 50 L) were established, and each experimental group was supplemented with three levels of Vit C (0, 500 and 1000 mg kg−1). The highest survival rate was observed in the lowest density group (five fish per 50 L) fed with 1000 mg kg−1 Vit C. A better feed conversion ratio and significantly higher protein efficiency ratio were found in the moderate stocking density group (10 fish per 50 L) fed with 500 mg kg−1 Vit C. Total leukocyte count (TLC), haemoglobin, and packed cell volume improved in Vit C‐fed groups. The total erythrocyte count (TEC) increased in groups fed Vit C and stocked at lower densities (5 and 10 fish per 50 L). Total serum protein (TPP) content increased when Vit C was added at a rate of 500 mg kg−1. Serum glucose and cortisol levels were significantly reduced in Vit C‐supplemented groups. Supplementation of Vit C at 500 mg kg−1 resulted in a significantly lower value of malondialdehyde (MDA). Thus, the findings confirm that the incorporation of Vit C in the basal diet promotes the growth and health status of L. gonius fry reared in the biofloc system at high‐density rearing.

Introduction: The complex and unresolved pathogenesis of schizophrenia has posed significant challenges to its diagnosis and treatment. While recent research has established a clear association between immune function and schizophrenia, the causal relationship between the two remains elusive. Methods: We employed a bidirectional two-sample Mendelian randomization approach to investigate the causal relationship between schizophrenia and 731 immune cell traits by utilizing public GWAS data. We further validated the causal relationship between schizophrenia and six types of white cell measures. Results: We found the overall causal effects of schizophrenia on immune cell traits were significantly higher than the reverse ones (0.011 ± 0.049 vs 0.001 ± 0.016, p < 0.001), implying that disease may lead to an increase in immune cells by itself. We also identified four immune cell traits that may increase the risk of schizophrenia: CD11c+ monocyte %monocyte (odds ratio (OR): 1.06, 95% confidence interval (CI): 1.03~1.09, FDR = 0.027), CD11c+ CD62L- monocyte %monocyte (OR:1.06, 95% CI: 1.03~1.09, FDR = 0.027), CD25 on IgD+ CD38- naive B cell (OR:1.03, 95% CI:1.01~1.06, FDR = 0.042), and CD86 on monocyte (OR = 1.04, 95% CI:1.01~1.06, FDR = 0.042). However, we did not detect any significant causal effects of schizophrenia on immune cell traits. Using the white blood cell traits data, we identified that schizophrenia increases the lymphocyte counts (OR:1.03, 95%CI: 1.01-1.04, FDR = 0.007), total white blood cell counts (OR:1.02, 95%CI: 1.01-1.04, FDR = 0.021) and monocyte counts (OR:1.02, 95%CI: 1.00-1.03, FDR = 0.034). The lymphocyte counts were nominally associated with the risk of schizophrenia (OR:1.08,95%CI:1.01-1.16, P=0.019). Discussion: Our study found that the causal relationship between schizophrenia and the immune system is complex, enhancing our understanding of the role of immune regulation in the development of this disorder. These findings offer new insights for exploring diagnostic and therapeutic options for schizophrenia. [ABSTRACT FROM AUTHOR]

Background: Numerous compelling observational studies have demonstrated a plausible correlation between the white blood cell count and the susceptibility to sudden sensorineural hearing loss (SSNHL). Nevertheless, the exact causal relationship between these two factors remains ambiguous. The objective of our study was to assess the causal impact of white blood cell count on sudden sensorineural hearing loss through the implementation of a bidirectional and multivariable Mendelian randomization (MR) methodology. Methods: Genetic data pertaining to white blood cell count were acquired from the Blood Cell Consortium, encompassing a total of 563,946 subjects. Concurrently, summary data on sudden sensorineural hearing loss were sourced from a Genome-Wide Association Study (GWAS), involving 196,592 participants, comprising 1,491 cases and 195,101 controls. The primary method employed for MR analysis was the Inverse Variance Weighted method (IVW), while sensitivity analysis utilized the Weighted Median method, MR-Egger method, and MRPRESSO method. Results: In IVW method, genetically predicted elevated lymphocyte cell count demonstrates an effective reduction in the risk of sudden sensorineural hearing loss (odds ratio = 0.747, 95% CI = 0.565-0.987, p = 0.04). These findings remain consistent in multivariate MR analysis, even after adjusting for monocyte cell count and neutrophil cell count levels (odds ratio = 0.929, 95% CI = 0.867-0.995, p = 0.036). However, there is no discernible evidence supporting a direct causal relationship between monocyte cell count and neutrophil cell count levels and the occurrence of SSNHL. Conclusion: Within the normal range, higher lymphocyte cell count levels exhibit a potential protective effect against SSNHL. Meanwhile, no direct causal relationship are identified between monocyte cell count and neutrophil cell count levels and the risk of SSNHL. [ABSTRACT FROM AUTHOR]

Objectives: This study aims to retrospectively analyze the clinical features of Stanford type A acute aortic dissection (TAAAD) based on Sun's modified classification, and to investigate whether the Sun's modified classification can be used to assess the risk of preoperative rupture. Methods: Clinical data was collected between January 2018 and June 2019. Data included patient demographics, history of disease, type of dissection according to the Sun's modified classification, time of onset, biochemical tests, and preoperative rupture. Results: A total of 387 patients with TAAAD who met the inclusion criteria of Sun's modified classification were included. There were more complex types, with 75, 151 and 140 patients in the type A1C, A2C and A3C groups, respectively. The age of the entire group of patients was 51.46 ± 12.65 years and 283 (73.1%) were male. The time from onset to the emergency room was 25.37 ± 30.78 h. There were a few cases of TAAAD combined with stroke, pericardial effusion, pleural effusion, and lower extremity and organ ischemia in the complex type group. The white blood cell count (WBC), neutrophil count (NEC) and blood amylase differed significantly between the groups. Three independent risk factors for preoperative rupture were identified: neutrophil count, blood potassium ion level, and platelet count. Binary logistic regression analysis showed that the Sun's modified classification could not be used to assess the risk of preoperative rupture in TAAAD. Conclusion: TAAAD was classified as the complex type in most patients. WBC, NEC and blood amylase were significantly different between the groups. NEC and serum potassium ion level were independent risk factors for preoperative rupture of TAAAD, while platelet count was its protective factor. More samples are needed to determine whether Sun's modified classification can be used to evaluate the risk of preoperative rupture. [ABSTRACT FROM AUTHOR]

The effects of meteorological conditions on IOP using a large-scale health examination cohort were investigated. There were a total of 811,854 measurements from 126,630 eyes of 63,839 subjects in 9 years from a health checkup cohort followed up annually for age, sex, body height, body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), and IOP. The effects of these variables and the meteorological data of daily average temperature (TP), daily average local atmospheric pressure (AP), daily average volumetric humidity (VH), and daily amount of rainfall (RF) on the day of IOP measurement on IOP were investigated. Several variables were significantly associated with IOP, including sex, age, body height, BMI, SBP, DBP, average TP, average AP, average VH, RF, white blood cell count, red blood cell count, hemoglobin, aspartate aminotransferase, alanine aminotransferase, guanosine triphosphate, calcium, and HbA1c. This study indicated a correlation between meteorological factors and IOP. Higher AP and RF were associated with elevated IOP, whereas higher TP and VH were associated with decreased IOP.

Background Methods Results Conclusion We investigated the clinical outcomes of involved‐field high‐dose (≥66 Gy) chemoradiotherapy (CRT) combined with respiratory motion management for esophageal squamous cell carcinoma (ESCC).Patients who underwent definitive CRT for histologically confirmed ESCC in our department between 2012 and 2018 were retrospectively analyzed. Respiratory motion management strategies included breath‐holding (63%) and mask immobilization (29%) based on individual measurements of respiratory tumor motion using radiographic fluoroscopy with endoscopically placed clip markers as landmarks. We evaluated patient characteristics, treatment efficacy, failure patterns, and toxicities.We enrolled 35 patients with a prescribed dose of 66–70 Gy in 33–35 fractions. The overall response rate within 6 months post‐CRT was 94.3%; the median follow‐up period for survivors was 43 months. The 2‐year overall survival (OS), progression‐free survival, and locoregional failure‐free survival rates were 51.4%, 42.9%, and 42.9%, respectively. A significant difference in OS was observed between patients with and without esophageal fistulas after CRT (p = 0.002, log‐rank test). Disease failure occurred in 16 patients (45.7%), including one (2.9%) with out‐of‐field regional nodal failure. Major grade 3 or higher toxicities included decreased white blood cell count (48.6%), neutrophil count (34.3%), and esophageal stenosis (31.4%). No grade 3 or higher cardiopulmonary toxicities were observed. Bronchial/tracheal tumor compression and a higher radiotherapy dose (70 Gy) were significantly correlated with esophageal fistulas.Involved‐field high‐dose CRT with respiratory motion management may be a feasible treatment option for ESCC. However, a comprehensive assessment of esophageal fistula risk is required to identify suitable candidates. [ABSTRACT FROM AUTHOR]

Background: Gangrene and perforation are severe complications of acute appendicitis, associated with a higher mortality rate compared to uncomplicated appendicitis. Accurate preoperative identification of Gangrenous or perforated appendicitis (GPA) is crucial for timely surgical intervention. Methods: This retrospective multicenter study includes 796 patients who underwent appendectomy. Univariate and multivariate logistic regression analyses are used to develop a nomogram model for predicting GPA based on laboratory tests and computed tomography (CT) findings. The model is validated using an external dataset. Results: Seven independent predictors were included in the nomogram: white blood cell count, lymphocyte count, D-dimer, serum glucose, albumin, maximum outer diameter of the appendix, and presence of appendiceal fecalith. The nomogram achieved good discrimination and calibration in both the training and testing sets. In the training set, the AUC was 0.806 (95%CI: 0.763–0.849), and the sensitivity and specificity were 82.1% and 66.9%, respectively. The Hosmer-Lemeshow test showed good calibration (P = 0.7378). In the testing set, the AUC was 0.799 (95%CI: 0.741–0.856), and the sensitivity and specificity were 70.5% and 75.3%, respectively. Decision curve analysis (DCA) confirmed the clinical utility of the nomogram. Conclusion: The laboratory test-CT nomogram model can effectively identify GPA patients, aiding in surgical decision-making and improving patient outcomes. [ABSTRACT FROM AUTHOR]

Introduction: There have been only a few cases showing the efficacy of pembrolizumab on granulocyte-colony-stimulating factor (G-CSF)-producing non-small-cell lung cancer (NSCLC) with high programmed cell death ligand 1 (PD-L1) expression. Herein, we report the first case showing the efficacy of pembrolizumab for G-CSF-producing NSCLC with high PD-L1 expression, although the patient had factors indicative of poor pembrolizumab efficacy, such as poor performance status (PS) due to the tumor-induced inflammation and corticosteroids administration. Case Presentation: A 77-year-old woman was diagnosed with G-CSF-producing NSCLC-not otherwise specified, classified as clinical stage IVB, T2N3M1c. She had fever and her PS was 3, and her C-reactive protein (CRP) was 6.47 mg/dL due to inflammation by a G-CSF-producing tumor. Thus, we initiated the administration of dexamethasone (3.3 mg/day). Her fever abated the next day, and CRP dropped to 3.22 mg/dL after 4 days. Driver mutations were negative, and PD-L1, tumor proportion score, was highly expressed at 100%. Thus, pembrolizumab was started. Subsequently, the white blood cell count decreased, and the tumor shrank, indicating a partial response. After three cycles of pembrolizumab therapy, the anorexia improved, and she was discharged. The patient developed sclerosing cholangitis after discharge. Therefore, the pembrolizumab treatment was discontinued. The primary lesion was enlarged, indicating progressive disease. However, the patient and her family did not want additional treatment. Finally, her progression-free survival and overall survival were 6 and 7 months, respectively. Conclusion: Pembrolizumab may be effective against G-CSF-producing NSCLC with high PD-L1 expression. Corticosteroids seemed to inhibit inflammation induced by the tumor, and exert the efficacy of pembrolizumab. [ABSTRACT FROM AUTHOR]

Background: With the improvement of anastomotic techniques and the iteration of anastomotic instruments, robotic intracorporeal suturing has become increasingly proficient. The era of fully intracorporeal anastomosis in robotic gastric cancer resection is emerging. This study aims to explore the impact of totally robotic distal gastrectomy (TRDG) and robotic-assisted distal gastrectomy (RADG) on patients' quality of life. Patients and methods: This study is a comparative retrospective study of propensity score matching. This study included 306 patients who underwent robotic distal gastrectomy for gastric cancer between June 2016 and December 2023 at our center. Covariates used in the propensity score included sex, age, BMI, ASA score, maximum tumour diameter, degree of histological differentiation, Pathological TNM stage, Pathological T stage, Pathological N stage, and Lauren classification. Outcome measures included operative time, intraoperative bleeding, time to first venting, time to first fluid intake, postoperative hospital stay, total hospitalization cost, total length of abdominal incision, postoperative complications, inflammatory response, body image, and quality of life. Results: According to the results of the study, compared with the RADG group, the TRDG group had a faster recovery time for gastrointestinal function (P = 0.025), shorter length of abdominal incision (P < 0.001), fewer days in the hospital (P = 0.006) less pain (P < 0.001), less need for additional analgesia (P = 0.013), and a postoperative white blood cell count (P < 0.001) and C-reactive protein content indexes were lower (P<0.001). In addition, the TRDG group had significantly better body imagery and cosmetic scores (P = 0.015), physical function (P = 0.039), role function (P = 0.046), and global function (P = 0.021) than the RARS group. Meanwhile, the TRDG group had milder symptoms of fatigue (P = 0.037) and pain (P < 0.001). The PASQ Total Subscale Score (P < 0.001) and Global Subscale Score (P < 0.001) were significantly lower in the TRDG group than in the RADG group at postoperative 3 months. Conclusion: Totally robotic distal gastrectomy has a smaller incision, faster gastrointestinal recovery time, fewer days of postoperative hospitalization, and lower inflammatory markers than robotic-assisted distal gastrectomy. At the same time, postoperative cosmetic and quality of life outcomes were satisfactory. Clinically, these benefits translate to enhanced patient recovery, reduced surgical trauma, and better postoperative outcomes. These findings could guide surgeons in selecting more effective surgical approaches for patients undergoing gastrectomy, leading to better overall patient satisfaction and outcomes.

Objective: Knowing factors that impact catheter stay duration is important since removing drainage catheters too early or late can have significant consequences. We present a single center retrospective study that analyzes multiple variables, including abscess size, white blood cell count, and patient age, to see if a correlation between them and duration of catheter stay exists. The inclusion criteria were patients that had abdominal abscesses treated with percutaneous abscess drainage using a pigtail catheter, ≥ 18 years of age, and had available medical images and records. 44 patients were included. Results: Among white blood cell count, patient age, and abscess volume, the only significant relationship with duration of catheter stay was abscess size (R = 0.42, p-value = 0.0049).

Background: In recent years, the addition of cetuximab to chemotherapy has improved treatment outcomes for patients with recurrent/metastatic head and neck squamous cell carcinoma (R/M HNSCC). In this study, we present the real-world survival data of R/M HNSCC patients who received cetuximab-containing regimens from thirteen medical centers in Taiwan, as well as a three-level risk stratification model for this patient population. Methods: This study enrolled R/M HNSCC patients from thirteen medical centers in Taiwan who received cetuximab-containing regimens from January 1, 2017 to June 6, 2022. The cases were divided into a training cohort and a validation cohort based on the start of treatment. Overall survival (OS) was evaluated in both cohorts and exploratory analysis was performed to identify associated adverse clinical and laboratory factors. The results of the exploratory analysis were used to construct a three-level risk stratification prediction model for OS. Results: A total of 1434 patients with R/M HNSCC were enrolled in this study and received cetuximab-containing regimens. The overall population had a median OS of 8.57 months (95% CI: 8.07 – 9.08). Multivariate analysis of the training cohort identified poor ECOG performance status, heavy alcohol consumption, and prior adjuvant CCRT or lack of prior RT as adverse prognostic factors. Comparison of laboratory data between patients with OS≦6 and OS > 6 also revealed unfavorable factors, including increased white blood cell count, decreased hemoglobin level, increased platelet count, increased absolute neutrophil count, decreased absolute lymphocyte count, and increased neutrophil-to-lymphocyte ratio. Using forward prediction, a three-level risk stratification prediction model was constructed using the variables of ECOG performance status, alcohol consumption, skin metastasis, modality of radiation therapy, hemoglobin level, and neutrophil-to-lymphocyte ratio. The median OS in the low-risk, intermediate-risk, and high-risk groups were 12.02 months (95% CI 10.44–13.61), 7.5 months (95% CI 7.33–8.17), and 4.01 months (95% CI 3.94–4.08), respectively, with a log-rank test p-value < 0.001. Conclusion: This study presents a three-level risk stratification model with strong prediction ability for OS in R/M HNSCC patients who received cetuximab-containing regimens. The results are based on real-world data and may provide valuable information for clinicians in treatment planning and future drug development. [ABSTRACT FROM AUTHOR]

Aims: The objective of this study is to compare the adverse events (AEs) associated with pralsetinib and selpercatinib. Methods: To evaluate the imbalance of AEs linked to pralsetinib and selpercatinib in real-world data, the reporting odds ratio (ROR) was utilized to detect potential signals of AEs. Stratified analysis was conducted to examine the differences in AEs occurring among different genders and age groups taking pralsetinib and selpercatinib. Results: FAERS received 891 reports for pralsetinib and 569 reports for selpercatinib. Our analysis confirmed expected AEs like hypertension, fatigue, and elevated transaminase levels. Unexpected AEs such as rhabdomyolysis, myocardial injury and cognitive disorder were associated with pralsetinib, while selpercatinib was linked with pulmonary embolism, deep vein thrombosis, and pericardial effusion. The risk of AEs such as decreased platelet count, anemia, decreased white blood cell count, pneumonitis, asthenia, and edema caused by pralsetinib is significantly higher than that of selpercatinib. In contrast, the risk of AEs such as ascites, elevated alanine aminotransferase, and elevated aspartate aminotransferase caused by selpercatinib is significantly higher than that of pralsetinib. Women treated with pralsetinib experience higher rates of hypertension, pulmonary embolism, and blurred vision than men, who are more susceptible to rhabdomyolysis. Adults between 18 and 65 years are more likely to experience taste disorder, edema, and pulmonary embolism than individuals older than 65, who are particularly vulnerable to hypertension. For patients treated with selpercatinib, males demonstrate a significantly higher incidence of QT prolongation, urinary tract infection, and dysphagia. Individuals aged 18 to 65 are more likely to experience pyrexia and pleural effusion than those older than 65, who are more prone to hypersensitivity. Conclusion: In the clinical administration of pralsetinib and selpercatinib, it is crucial to monitor the effects of gender and age on AEs and to be vigilant for unlisted AEs. [ABSTRACT FROM AUTHOR]

Background A common acute gastrointestinal inflammatory condition in both children and adults is appendicitis, often requiring surgical intervention and hospitalization. An estimated 14,000 persons in the Netherlands get an appendectomy annually to address suspected appendicitis. Acute appendicitis may be delineated into two distinct forms: basic and complex. A suppurative or phlegmonous appendicitis is a condition marked by inflammation, ulceration, or thrombosis in the transmural layer of the appendix, with or without surrounding pus. Complex appendicitis includes perforated appendicitis, gangrenous (transmural inflammation with necrosis) appendicitis, and/or appendicitis of the pelvis or abdomen accompanied by abscess development. An estimated 25-30% of patients are classified as complex appendicitis. Timely and appropriate administration of preventive antibiotics reduces the likelihood of surgical site infections (SSIs) after surgery. Nevertheless, there is no conclusive guideline regarding the duration of antibiotic use. Several randomized controlled studies have recommended a single preoperative prophylactic dose. Aim The aimed to determine the need for postoperative antibiotics after laparoscopic appendicectomy for nonperforated appendicitis. Material and Method This randomized control research (RCT) was conducted by the Department of General Surgery. This research included all patients who were hospitalized with acute appendicitis and had emergency open appendectomy. Data on the patients' demographics, medical histories, and details of their clinical exams were recorded on a pre-established proforma. Furthermore, apart from conventional examinations such as an abdominal ultrasonography, also conducted were tests including blood urea, serum creatinine, and complete blood counts. Random assignment of groups was conducted using the opaque envelope method. Seventy opaque polymer envelopes containing cards were manufactured. Among these envelopes, thirty-five had a card identifying the study group, Group A, while the other thirty-five contained a card identifying the control group, Group B. Results The average age of Group B was 28.62±8.52 years, while the average age of Group A was 28.54±9.62 years. Baseline right iliac fossa discomfort was seen in every participant in the study. The three patients in group A and the two patients in group B who had grade III SSIs were treated with conservative therapy. There was no statistically significant disparity in the occurrence of surgical site infections (SSIs) between the two groups. No significant differences were seen between the two groups in terms of mean age, gender distribution, pain, fever, nausea/vomiting, McBurney's soreness, bowel sounds, total leukocyte count, ultrasonography, diagnosis, and histology report. While the average hospitalized duration of group B was greater than that of group A, there was no statistically significant disparity. Conclusion A single preoperative dosage of the preventive antibiotics cefotaxime and metronidazole at the time of induction is enough to lower the incidence of postoperative surgical site infections, and further postoperative doses do not provide a statistically meaningful advantage. A comprehensive investigation including a range of abdominal procedures is necessary to determine the true need of postoperative prophylactic antibiotics in minimizing surgical site infections (SSIs).

Background and Aim: There is a scarcity of Indian studies on infective endocarditis. Additionally, the majority of research has focused on the paediatric age group. The purpose of this study was to investigate the microorganisms responsible for infective endocarditis in patients with rheumatic heart disease in patients attending Medicine OPD of Smt NHL Municipal Medical College, Ahmedabad. Additionally, the study aimed to assess the effectiveness of medical treatment and evaluate the prognosis of the cases. Material and Methods: Our study took place at the Department of General Medicine, a Smt. NHL Municipal Medical College, Ahmedabad, over the course of one year. We thoroughly investigated patients who were clinically suspected of having infective endocarditis. A study was conducted on 40 patients with Rheumatic heart disease who met the diagnostic criteria for infective endocarditis. A comprehensive set of medical tests were performed, including a complete hemogram, urinalysis specifically to check for microscopic haematuria, chest Xray, and EGG. Prior to starting treatment, blood cultures were collected. A comprehensive M mode and 2 D echocardiographic examination was conducted for all individuals suspected of having the condition, with additional TEE performed for cases that required further clarification. Results: A significant number of patients presented with a combination of mitral and aortic valve lesions. The most frequently observed combined lesions in our patients were mitral and aortic regurgitation. The patients included in our study experienced mild to moderate grade fever. At the time of admission, nineteen patients in the study group had a leukocyte count exceeding 10,000 cells per cubic millimetre. The majority of patients in the study group exhibited elevated ESR levels. Out of the total 40 patients, 11 had a positive blood culture (27.5%). Surprisingly, in 29 patients, the blood culture remained negative even after multiple sample collections and a seven-day incubation period. Most patients initially received a standard recommended dose of injection Penicillin G and Gentamicin on an empirical basis. However, as per the sensitivity pattern, appropriate antibiotics were administered thereafter. Conclusion: Treatment of endocarditis was more successful when suitable antibiotics were started after culture and sensitivity rather than the empirical treatment. [ABSTRACT FROM AUTHOR]

Background: The decision to administer palliative radiotherapy (RT) to patients with bone metastases (BMs), as well as the selection of treatment protocols (dose, fractionation), requires an accurate assessment of survival expectancy. In this study, we aimed to develop three predictive models (PMs) to estimate short‐, intermediate‐, and long‐term overall survival (OS) for patients in this clinical setting. Materials and Methods: This study constitutes a sub‐analysis of the PRAIS trial, a longitudinal observational study collecting data from patients referred to participating centers to receive palliative RT for cancer‐induced bone pain. Our analysis encompassed 567 patients from the PRAIS trial database. The primary objectives were to ascertain the correlation between clinical and laboratory parameters with the OS rates at three distinct time points (short: 3 weeks; intermediate: 24 weeks; prolonged: 52 weeks) and to construct PMs for prognosis. We employed machine learning techniques, comprising the following steps: (i) identification of reliable prognostic variables and training; (ii) validation and testing of the model using the selected variables. The selection of variables was accomplished using the LASSO method (Least Absolute Shrinkage and Selection Operator). The model performance was assessed using receiver operator characteristic curves (ROC) and the area under the curve (AUC). Results: Our analysis demonstrated a significant impact of clinical parameters (primary tumor site, presence of non‐bone metastases, steroids and opioid intake, food intake, and body mass index) and laboratory parameters (interleukin 8 [IL‐8], chloride levels, C‐reactive protein, white blood cell count, and lymphocyte count) on OS. Notably, different factors were associated with the different times for OS with only IL‐8 included both in the PMs for short‐ and long‐term OS. The AUC values for ROC curves for 3‐week, 24‐week, and 52‐week OS were 0.901, 0.767, and 0.806, respectively. Conclusions: We successfully developed three PMs for OS based on easily accessible clinical and laboratory parameters for patients referred to palliative RT for painful BMs. While our findings are promising, it is important to recognize that this was an exploratory trial. The implementation of these tools into clinical practice warrants further investigation and confirmation through subsequent studies with separate databases. [ABSTRACT FROM AUTHOR]

Objective: Acute appendicitis is one of the most common causes of abdominal pain requiring surgical intervention in children. Although clinical and imaging modalities play a central role in disease diagnosis, laboratory markers, such as white blood cell (WBC) count, neutrophil count, and electrolyte disturbances, particularly sodium levels, have been explored as potential indicators of disease severity. This study aimed to evaluate the relationship between serum sodium levels, WBC and neutrophil counts, and their respective ratios with the diagnosis and severity of appendicitis. Methods: This retrospective analysis included 176 pediatric patients who underwent appendectomy. Patients were divided into three groups based on pathological findings: Group 1 (non-appendicitis, n=59), group 2 (acute appendicitis, n=82), and group 3 (perforated appendicitis, n=35). WBC, neutrophil, and sodium levels were recorded. ANOVA and post-hoc Tukey's tests were used to assess differences between groups. A logistic regression model was employed to evaluate the combined ability of WBC, neutrophil, and sodium levels to distinguish group 1 from groups 2 and 3, and the model's performance was evaluated using the area under the ROC curve (AUC). Results: Significant differences were observed between group 1 and groups 2 and 3 regarding WBC (p<0.001), neutrophil (p<0.001), and sodium levels (p<0.001). Group 3 had the highest WBC count (17,123±4,491 cells/µL) and the lowest sodium levels (132.5±1.4 mEq/L), whereas group 1 had the lowest WBC count (10,660±3,804 cells/µL) and the highest sodium levels (137.5±2.6 mEq/L). Logistic regression analysis of the combined WBC, neutrophil, and sodium values obtained an AUC of 0.703, indicating moderate diagnostic utility. Conclusion: This study demonstrated that WBC count, neutrophil count, and sodium level, as well as their ratios, can aid in diagnosing appendicitis in pediatric patients. Although sodium levels were significantly lower in patients with appendicitis, no significant difference was found between acute and perforated appendicitis. The WBC/sodium and neutrophil/sodium ratios could be valuable in clinical practice, especially for distinguishing between appendicitis and non-appendicitis cases. Further research is warranted to explore their utility in larger populations. [ABSTRACT FROM AUTHOR]

Simple Summary: This study investigates predictive factors for distinguishing benign and malignant multifocal hepatic lesions in dogs using ultrasound, hematology, and serum biochemistry. The results show significant differences in hematological and blood chemical parameters, and ultrasonographic parameters. The hepatobiliary ultrasound score and lesion homogeneity show significant differences and high accuracy in predicting malignant multifocal liver lesions, making them effective parameters for screening in dogs. Multifocal hepatic lesions in dogs arise from various benign and malignant liver diseases. Diagnosing these lesions is challenging because clinical signs, hematological data, and serum biochemistry are not definitive indicators. Ultrasound is utilized as a diagnostic imaging tool to evaluate liver parenchyma and detect hepatic lesions. This study aims to investigate the predictive factors that differentiate between benign and malignant multifocal hepatic lesions by examining ultrasound characteristics, blood tests, and serum biochemistry. In total, 43 dogs with multifocal hepatic lesions were included in this study. All dogs were classified into benign hepatic diseases (n = 32) and malignant haptic diseases (n = 11). For all dogs, their liver characteristics, lesion characteristics, and hepatobiliary ultrasound score by ultrasound were evaluated and we collected individual clinicopathological data for analysis. The findings of the univariate analysis revealed significant differences in four hematological and blood chemical parameters (hematocrit, white blood cell count, aspartate transaminase (AST), and alkaline phosphatase (ALP)) and six ultrasonographic parameters (liver parenchymal echogenicity, lesion homogeneity, lesion echogenicity, maximum lesion dimension, average lesion dimension, and hepatobiliary ultrasound score). Using multivariate analysis, only two parameters, hepatobiliary ultrasound score and lesion homogeneity, showed significant differences (p-value < 0.001 and p-value = 0.011, respectively). Additionally, these parameters demonstrated high accuracy in predicting malignant multifocal liver lesions, with accuracy rates of 97.67% and 93.02%, respectively. Therefore, the hepatobiliary ultrasound score and lesion homogeneity are considered effective parameters for screening malignant multifocal liver lesions in dogs. [ABSTRACT FROM AUTHOR]

Sepsis remains a significant contributor to neonatal mortality worldwide. However, the nonspecific nature of sepsis symptoms in neonates often leads to the necessity of empirical treatment, placing a burden of ineffective treatment on patients. Furthermore, the global challenge of antimicrobial resistance is exacerbating the situation. Artificial intelligence (AI) is transforming medical practice and in hospital settings. AI shows great potential for assessing sepsis risk and devising optimal treatment strategies. Background/Objectives: This review aims to investigate the application of AI in the detection and management of neonatal sepsis. Methods: A systematic literature review (SLR) evaluating AI methods in modeling and classifying sepsis between 1 January 2014, and 1 January 2024, was conducted. PubMed, Scopus, Cochrane, and Web of Science were systematically searched for English-language studies focusing on neonatal sepsis. Results: The analyzed studies predominantly utilized retrospective electronic medical record (EMR) data to develop, validate, and test AI models to predict sepsis occurrence and relevant parameters. Key predictors included low gestational age, low birth weight, high results of C-reactive protein and white blood cell counts, and tachycardia and respiratory failure. Machine learning models such as logistic regression, random forest, K-nearest neighbor (KNN), support vector machine (SVM), and XGBoost demonstrated effectiveness in this context. Conclusions: The summarized results of this review highlight the great promise of AI as a clinical decision support system for diagnostics, risk assessment, and personalized therapy selection in managing neonatal sepsis.

Background: Postimplantation syndrome (PIS) is a known inflammatory response following endovascular stent placement, yet comparative data between venous and arterial stenting remains limited. This study seeks to evaluate the incidence, characteristics, and clinical implications of PIS across these two distinct vascular territories. Methods: We retrospectively analyzed 191 patients who underwent either venous (n = 36) or arterial (n = 155) stent placement. Data collection encompassed demographic profiles, perioperative laboratory findings, and clinical outcomes. The primary endpoint was the incidence of PIS, defined as the presence of fever (≥38 °C), leukocytosis, and elevated C-reactive protein (CRP) within 30 days postprocedure. Secondary outcomes included length of hospital and ICU stay, incidence of endoleaks, reintervention rates, and 30-day mortality. Comparative statistical analyses were conducted to assess differences between the venous and arterial stent groups. Results: PIS was observed more frequently in arterial stent patients, as evidenced by significantly elevated postoperative white blood cell counts at 24 and 48 h (p = 0.046 and p = 0.014, respectively), along with borderline CRP increases (p = 0.052). Fever occurrence peaked at 72 and 96 h postprocedure, predominantly in the arterial cohort. Furthermore, patients with arterial stents had significantly longer hospital stays (5.59 ± 0.46 days vs. 3.42 ± 0.36 days; p = 0.0018) and a higher rate of 30-day endoleaks (7.1% vs. 0%; p = 0.005). Despite similar mortality and major adverse cardiac event (MACE) rates between groups, arterial stent patients exhibited a greater need for reintervention. While PIS was less common among venous stent recipients, its potential impact on postoperative recovery warrants careful monitoring. Conclusions: Arterial stenting is associated with a higher incidence of PIS and a more pronounced systemic inflammatory response, contributing to longer hospitalization and increased postoperative complications. Although venous stent patients experience PIS less frequently, its occurrence should not be overlooked, as it may influence overall recovery and clinical outcomes. Recognition and management of PIS in both venous and arterial stent patients are critical to improving patient care and optimizing procedural success. [ABSTRACT FROM AUTHOR]

Background/Objectives: The management of acute uncomplicated diverticulitis (AUD) has shifted towards outpatient care in the last decade, challenging the traditional inpatient approach. We aimed to analyze the safety and feasibility of a structured outpatient treatment pathway for AUD in a tertiary hospital. Methods: We conducted a retrospective observational cohort analysis of patients who underwent outpatient management for AUD at the Geneva University Hospitals from 2019 to 2021. Patient demographics, selection criteria, treatment protocols, and outcomes were analyzed. Results: Two-hundred and twenty patients were included in the outpatient cohort. Four patients (1.8%) required hospitalization due to the failure of outpatient management, whereas the majority of patients (116 patients, 98.2%) experienced a successful resolution of their symptoms without hospitalization. In a univariate analysis, factors associated with treatment failure included elevated white blood cell counts at admission (14 G/l vs. 10.6 G/l, p = 0.049) and the first follow-up appointment, (10.7 G/l vs. 7.4 G/l, p = 0.011) and the presence of free air on their CT scan (25% vs. 2,3%, p = 0.033). In a multivariate analysis, the presence of free air was the only identified risk factor for unsuccessful outpatient management (p = 0.05). We observed high rates of follow-up compliance (99.1%). Conclusion: Under the condition of a warranted outpatient follow-up appointment and with adequate selection criteria, outpatient management appears to be an effective approach for most patients with AUD, emphasizing the importance of tailored therapeutic interventions and vigilant clinical assessments for optimal outcomes.

Objectives: Post-myocardial infarction ventricular septal rupture (PIVSR) is one of the most severe types of mechanical complications after acute myocardial infarction (AMI) with high mortality and poor prognosis. The risk factors for short-term mortality of patients with PIVSR may be not widely recognized. We aimed to assess the prevalence and short-term mortality risk predictors of PIVSR. Methods: A total of 62 patients with a diagnosis of PIVSR were admitted to three top general public hospitals in Chongqing, China. Clinical characteristics and short-term outcomes of patients with PIVSR were compared. Predictors of PIVSR were assessed using logistic regression analysis. Results: Mean age was 70.7 ± 10.7 years (38.7% female). The overall in-hospital mortality of PIVSR remained high (71%). Most (47/62) of the patients were in Killip class III or IV at the time of rupture diagnosis. Logistic regression analysis revealed that white blood cell count (WBC, OR 1.619, 95% CI 1.172–2.237, P = 0.005), cardiogenic shock (OR 47.706, 95%CI 2.859-795.945, P = 0.007) and left ventricular ejection fraction (LVEF, OR 0.803, 95%CI 0.689–0.936, P = 0.009) were independent risk factors of in-hospital early mortality. The nomogram developed for predicting the risk of short-term mortality showed a robust discrimination, with an area under the receiver operating characteristic curve (AUC) of 0.956 (95%CI 0.912-1.000). Conclusion: The short-term mortality of PIVSR remained high. WBC, cardiogenic shock, and LVEF were the independent predictive factors of short-term mortality. Our nomogram might be used to predict early mortality of patients with PIVSR. [ABSTRACT FROM AUTHOR]

Aims: The recommended dosage of pegylated recombinant human granulocyte‐colony stimulating factor (PEG‐rhG‐CSF) for Western chemotherapy patients is 6 mg per cycle. However, for Eastern Asians, the optimal dose remains unknown. Methods: This open‐label, randomized, non‐inferiority trial (NCT05283616) enrolled Chinese female breast cancer patients receiving adjuvant chemotherapy. Participants were randomized to receive either 3 or 6 mg of PEG‐rhG‐CSF per cycle, stratified by body weight (BW; ≤60 kg vs. >60 kg). The primary endpoint was timely absolute neutrophil count (ANC) recovery before the second cycle of chemotherapy. Results: A total of 122 patients were randomized and 116 were included for efficacy analyses. The timely ANC recovery rate in the 3 mg arm was 89.8%, compared to 93.0% in the 6 mg arm (one‐sided 95% confidence interval [CI] lower limit for difference: −11.7%), meeting the prespecified non‐inferiority margin of 15%. The rate was 93.3% with PEG‐rhG‐CSF 3 mg and 96.6% with 6 mg in patients with BW ≤ 60 kg, and 86.2% and 89.3%, respectively, in those with BW > 60 kg. Although the incidence of severe neutropenia was similar across arms, the occurrence of excessively high ANC and white blood cell counts was higher in the 6 mg arm. No grade ≥3 adverse events related to PEG‐rhG‐CSF occurred. Conclusion: Three milligrams of PEG‐rhG‐CSF per cycle provided non‐inferior neutrophil protection and attenuated neutrophil overshoot compared to 6 mg doses. This low‐dose regimen could be a new supportive care option for Chinese breast cancer patients receiving anthracycline‐based adjuvant chemotherapy. [ABSTRACT FROM AUTHOR]

The list of standard abbreviations for JDS is available at adsa.org/jds-abbreviations-24. Nonstandard abbreviations are available in the Notes. A meta-analysis was performed to investigate the effects of capsaicin (CAP) on lactational performance and blood chemistry and cell counts in dairy cattle. The database comprised 11 peer-reviewed studies published between 2011 and 2024. The overall effect of CAP, challenge (e.g., ketosis, glucose tolerance, LPS), and dose were considered explanatory variables in the analysis. Lactation performance response variables included DMI, milk yield (MY), ECM yield, feed efficiency (FE), milk components, and BW. Hematological response variables included red and white blood cell counts and blood BHB, total fatty acids, insulin, and glucose concentrations. Data were analyzed using random- and mixed-effect models in the "robumeta" package in RStudio. Milk yield was increased by 2.9% by CAP when compared with control. Capsaicin supplementation increased FE by 3.4% compared with control. Milk fat concentration and yield were also increased by CAP compared with control by 2.6% and 4.0%, respectively. Blood glucose concentrations were decreased 2.5% by CAP supplementation, whereas insulin levels were unaffected. Cows fed CAP during a challenge had higher MY and FE and tended to have lower blood glucose than their control counterparts. Overall, this analysis suggests that CAP supplementation may be directly affecting host physiology by altering glucose metabolism, but further research to define the mechanism is warranted.

Background: There is limited data on the association between inflammation and the formation of early left ventricular thrombus (LVT) following ST‐elevation myocardial infarction (STEMI). This study aimed to explore the predictive value of several inflammatory biomarkers for LVT formation following STEMI. Methods and Results: Our cohort included 2534 consecutive patients admitted to the cardiac intensive care unit (CICU) with STEMI. The final analysis included 51 patients with LVT and 102 patients without LVT, matched for age, sex, anterior infarct and ejection fraction. Upon admission, patients with LVT had higher white blood cell counts (WBC) (12.8 ± 7 vs. 12.4 ± 4 ×103/µL, p = 0.01), higher absolute neutrophil counts (10.5 ± 4 vs. 8.6 ± 4 ×103/µL, p = 0.003), neutrophil‐to‐lymphocyte ratio (8.2 ± 6 vs. 4.8 ± 4, p = 0.04), and C‐reactive protein (CRP) levels (35.9 ± 62 vs. 18.6 ± 40 mg/L, p = 0.04). Peak values for WBC and CRP were also higher in the LVT group (17.8 ± 8 vs. 14.6 ± 5 ×103/µL, p = 0.003 and 95.8 ± 82 vs. 64.2 ± 76 mg/L, p = 0.02, respectively). In univariate regression analysis, WBC upon admission (OR: 1.12, 95% CI: 1.02–1.21, p = 0.02), peak WBC (OR: 1.09, 95% CI: 1.02–1.17, p = 0.009), neutrophil count upon admission (OR: 1.15, 95% CI: 1.04–1.26, p = 0.004), and peak CRP (OR: 1.01, 95% CI: 1–1.01, p = 0.03) predicted LVT formation, which was also evident in multivariate regression models. Conclusion: WBC and neutrophil counts upon admission, as well as peak WBC and CRP, have additional predictive value for LVT formation following STEMI, beyond classical risk factors.

Backgroud: Intussusception is a common acute abdominal disease in children, often leading to acute ileus in infants and young children. Objective: This study aimed to develop and validate a nomogram for predicting recurrent intussusception in children within 48 h after pneumatic reduction of primary intussusception. Methods: Clinical data of children with acute intussusception admitted to multiple hospitals from March 2019 to March 2021 were retrospectively analyzed. The children were divided into a successful reductioncontrol group (control group) and a recurrent intussusception group (RI group) according to the results of pneumatic reduction. Results: A total of 2406 cases were included in this study, including 2198 control group and 208 RI group. In the total sample, 1684 cases were trained and 722 cases were verified. A logistic regression analysis was conducted to establish a predictive model based on age, abdominal pain time, white blood cells count, and hypersensitive C-reactive protein levels as independent predictors of intussusception recurrence. The nomogram successfully predicted recurrent intussusception after pneumatic reduction. Conclusion: In this study, a nomogram was developed based on clinical risk factors to predict recurrent intussusception following pneumatic reduction in children. Age, abdominal pain time, white blood cell counts, and hypersensitive C-reactive protein levels were identified as predictors and incorporated into the nomogram. Internal validation demonstrated that this nomogram can offer a clear and convenient tool for identifying risk factors for recurrence of intussusception in children undergoing pneumatic reduction.

Aims: It is unclear whether activated partial thromboplastin time (aPTT) or anti‐Xa is more accurate for monitoring heparin anticoagulation in mechanical circulatory support (MCS) patients. This study investigates the relationship between aPTT and anti‐Xa in MCS patients and identifies predictors of discordance. Methods and results: aPTT and anti‐Xa were simultaneously measured in a prospective cohort of MCS patients receiving unfractionated heparin at a tertiary academic medical centre. Therapeutic aPTT and anti‐Xa levels were 60–100 s and 0.3–0.7 IU/mL, respectively, and concordance was defined as both levels being subtherapeutic, therapeutic, or supratherapeutic. To identify predictors of discordance, both a machine learning random forest model and a multivariate regression model were applied to patient demographics, device type, and 14 laboratory variables; 23 001 pairs of simultaneously measured aPTT/anti‐Xa were collected from 699 MCS patients. aPTT and anti‐Xa were concordant in 35.5% of paired observations and discordant in 64.5% (aPTT > antiXa 61.5%; aPTT < antiXa 3.0%). Discordance with a high aPTT relative to anti‐Xa (aPTT > antiXa) was associated with high INR, eGFR, and total bilirubin, as well as low platelets, haemoglobin, pre‐albumin, white blood cell count, and haptoglobin. Total artificial heart and durable ventricular assist devices were more likely to be associated with aPTT > anti‐Xa than temporary MCS devices. Conclusions: aPTT and anti‐Xa were frequently discordant in MCS patients receiving heparin anticoagulation. Clinical conditions common in MCS patients such as concurrent warfarin use, malnutrition, haemolysis, and thrombocytopenia, as well as durable type of MCS devices were associated with a high aPTT relative to anti‐Xa.

Objective: The objective of this study was to ascertain pegloticase persistence and adverse events associated with concomitant immunomodulatory drug treatment in patients with gout. Methods: We conducted a retrospective analysis of patients with gout using the American College of Rheumatology's Rheumatology Informatics System for Effectiveness registry from January 2016 through June 2020. The first pegloticase infusion defined the index date. Based on concomitant immunomodulatory drug treatment, we identified three exposure groups: (1) immunomodulatory drug initiators (patients initiating an immunomodulatory prescription ±60 days from the index date), (2) prevalent immunomodulatory drug recipients (patients receiving their first immunomodulatory drug prescription >60 days before the index date with at least one prescription within ±60 days of the index date), and (3) immunomodulatory nonrecipients (patients receiving pegloticase without concomitant immunomodulatory drugs). We calculated the proportion of patients who achieved serum urate levels ≤6 mg/dL and who had laboratory abnormalities (white blood cell count <3.4 x 109/L, platelet count <135,000, hematocrit level <30%, alanine aminotransferase or aspartate aminotransferase level ≥1.5 times the upper limit normal value) within 180 days after the index date. Cox regression analyzed time to pegloticase discontinuation, controlling for potential confounders. Results: We identified 700 pegloticase recipients (91 immunomodulatory drug initiators, 33 prevalent immunomodulatory drug recipients, and 576 nonrecipients), with a median follow‐up of 14 months. Immunomodulatory drug recipients were less likely to discontinue pegloticase. The adjusted hazard ratios of pegloticase discontinuation associated with concomitant immunomodulatory drug initiation and prevalent treatment were 0.52 (95% confidence interval [CI] 0.37–0.75) and 0.69 (95% CI 0.42–1.16), respectively. Laboratory abnormalities were uncommon (<5%) and were not higher in concomitant immunomodulatory drug treatment. Conclusion: Consistent with clinical trials, results from this large observational registry suggest that concomitant immunomodulatory drug treatment improves pegloticase persistence.

Objectives: This study aimed to establish reference intervals (RIs) for Russian adults for hematological parameters including related iron markers and vitamins. Sources of variation of reference values (RVs) and needs for secondary exclusion were explored for proper derivations of RIs. Methods: Following the harmonized protocol of the IFCC Committee on Reference Intervals and Decision Limits (C-RIDL), 506 healthy Russians (age 18−80; 46% male) were recruited. Complete blood counts (CBC) and leukocyte differentials, iron markers, vitamin B12, and folate were measured by Beckman Coulter's analyzers. Sources of variation were analyzed by multiple regression analysis, and ANOVAs, and the need for partitioning RVs was decided accordingly. Two schemes of excluding latent anemia were compared: (1) latent abnormal values exclusion method (LAVE) based on associations among CBC parameters, or (2) explicit exclusion of individuals with either ferritin or iron below the respective lower limit of the manufacturer. RIs were determined by the parametric method using two-parameter Box-Cox formula. Results: Gender-specific RIs were required for most analytes, while age-specific RIs were set only for ferritin in females. A BMI-related increase in RVs was prominently observed for reticulocyte parameters, hence we chose to exclude individuals with BMI>28 kg/m2 when establishing the RIs. The LAVE method was more effective in excluding individuals with latent anemia, than exclusion based on low ferritin and/or iron values. International comparison revealed that Russian RIs featured a lower side shift of platelet counts. Similar to African countries, Russian RIs for total leukocyte and neutrophil counts were lower compared to most of other countries. Conclusion: RIs for the Russian population for 34 hematological and related parameters were established using up-to-date methods proposed by C-RIDL. Reducing the influences of latent anemia and obesity on RIs was crucial for erythrocyte parameters. Low levels of Russian RIs observed for platelet and neutrophil counts need further investigation.

Background: We aimed to investigate the association between selected inflammatory and immune variables and survival of dogs with myxomatous mitral valve disease (MMVD). We evaluated data of 62 client-owned dogs with MMVD, grouped into preclinical, stable congestive heart failure (CHF) and unstable CHF. Univariate Cox proportional hazards regression analysis was used to quantify the association of white blood cell count, concentrations and percentages of T lymphocytes and their subtypes (T helper lymphocytes, cytotoxic T lymphocytes, double positive T lymphocytes, double negative T lymphocytes) and B lymphocytes with survival. P values < 0.1 in individual groups and P values < 0.05 in the group of all patients were considered significant. Spearman correlation coefficients between significant covariates were calculated to assess the relationships among variables and with survival. Results: In the preclinical group, percentage of double positive T lymphocytes was negatively associated with survival (hazard ratio (HR) = 2.328; P = 0.051). In the unstable CHF, T lymphocyte (HR = 1.613; P = 0.085), cytotoxic T lymphocyte (HR = 1.562; P = 0.048), double positive (HR = 1.751; P = 0.042), and double negative T lymphocyte (HR = 1.613; P = 0.096) concentrations were negatively associated with survival, as well as cytotoxic T lymphocyte (HR = 1.502; P = 0.007) concentration in the group of all patients. The percentage of T helper lymphocytes was positively associated with survival in the unstable CHF (HR = 0.604; P = 0.053) and in the group of all patients (HR = 0.733; P = 0.044). The concentration of cytotoxic T lymphocytes positively correlated with left atrial to aortic ratio (LA/Ao) (rho = 0.259, P = 0.037), and peak velocity of early diastolic mitral flow (rho = 0.259, P = 0.039), whereas the percentage of T helper lymphocytes negatively correlated with left atrial to aortic ratio (LA/Ao) (rho = -0.212, P = 0.090) and early to late mitral flow ratio (rho = -0.232, P = 0.072). Conclusions: Cytotoxic T lymphocytes, T helper lymphocytes, double positive and double negative T lymphocytes as well as biomarkers cardiac troponin I, N-terminal pro-B-type natriuretic peptide, C-reactive protein are implicated in the progression of MMVD.

Background: In septic arthritis, joint lavage can be performed using arthrocentesis (articular needle aspiration) or arthrotomy. The use of fluoroscopy to guide the puncture involves radiation. Ultrasound (US) guidance is still little recommended to guide the treatment of septic arthritis in children. We wanted to know whether treating septic arthritis in children was feasible and safe under ultrasound (US) guidance. Methods: We retrospectively included 67 children (mean age, 3.0 years; range: 1 month–12 years) treated for septic arthritis of the hip, shoulder, or ankle using arthrocentesis or arthrotomy under US or fluoroscopic guidance (non-US group) with at least two years of follow-up. Results: We found no significant difference between the groups. After arthrocentesis, patients in the US group remained in hospital for 0.8 days longer than those in the non-US group, but the difference was not significant. After arthrotomy, the arthrotomy-US group required 0.4 more days of hospitalization than the non-US group, but the difference was not significant. Patients in the US group exhibited higher initial CRP and WBC values than patients treated without US, although the differences were not significant. The WBC values of the arthrocentesis-US groups were higher than those of the non-US groups initially and at 72 h, but non significantly so; they became similar on day 5. Three puncture failures required arthrotomy (two under US guidance). Three patients required early revision surgery: one had undergone arthrocentesis with US, one arthrocentesis without US, and one arthrotomy without US. At the last follow-up, there were no clinical sequelae but two hip arthrotomies (one US and one non-US child) showed asymptomatic calcifications. Conclusions: US guidance is feasible and safe for treating septic arthritis in children, visualizing structures not shown by X-rays and avoiding radiation exposure during surgery. Level of evidence: IV (case series). Trial registration: IRB-MTP_2021_05_202100781 [ABSTRACT FROM AUTHOR]

Objective: This study aimed to compare clinical features, laboratory findings, and immunotherapy responses between antibody-positive and antibodynegative Autoimmune encephalitis (AE) patients. Methods: A retrospective analysis of clinical data from 60 AE patients (33 antibody-positive, 27 antibody-negative) diagnosed at Zhongshan Hospital of Xiamen University between January 1, 2016, and March 1, 2024 was conducted. Disease severity and treatment response were assessed using the modified Rankin Scale (mRS) and the Clinical Assessment Scale for Autoimmune Encephalitis (CASE). Results: Antibody-positive AE patients more frequently presented with multiple symptoms (≥4 symptoms: 39.4% vs. 14.8%, p = 0.036). They demonstrated significantly elevated serum IgG concentrations (p = 0.010) and cerebrospinal fluid (CSF) leukocyte counts (p = 0.014). Conversely, antibody-negative AE patients presented with higher CSF total protein levels (p = 0.025) and albumin quotients (p = 0.018), indicative of more severe blood-brain barrier disruption. Antibody-positive AE patients more frequently received combination first-line immunotherapy (75.8% vs. 48.1%, p = 0.027) and exhibited superior treatment outcomes (90.9% vs. 70%, p = 0.022). Among critically ill patients (peak mRS score: 4-5), improvement in CASE scores was markedly greater in the antibodypositive cohort (median: 4.50 vs. 1.00, p = 0.024). Conclusion: Antibody-positive AE patients manifested a more diverse symptom spectrum, elevated serum IgG concentrations and CSF leukocyte counts, and superior responses to immunotherapy. In contrast, antibody-negative AE patients demonstrated more severe blood-brain barrier dysfunction, as evidenced by higher CSF total protein concentrations and albumin quotients.

Peritoneal dialysis-associated peritonitis (PDAP) is a frequent complication of peritoneal dialysis. The guidelines from the International Society for Peritoneal Dialysis (ISPD) suggest administering teicoplanin through the peritoneal route to treat PDAP, but do not specify the ideal concentration for peritoneal dialysis effluent (PDE). Patients meeting the trial criteria for PDAP in our hospital between July 2022 and December 2023 were enrolled. Data on PDE white blood cell count, PDE neutrophil percentage, clinical symptoms, CRP, and PCT were gathered pre- and post-treatment. Incidences of adverse drug reaction (ADR) and case numbers during treatment were recorded. Subsequently, patients were categorized into cured and uncured groups for evaluating the relationship between PDE teicoplanin concentration and treatment effectiveness. The selfcontrol study results on teicoplanin efficacy indicated intraperitoneal teicoplanin administration achieved an efficacy rate of 88.9% and an ADR incidence of 5.5% in treating PDAP patients. There was no observed correlation between teicoplanin blood concentration and PDE concentration. PDE teicoplanin concentrations on days 1, 3, 5, and 7 post-dosing were higher inthe cured group, with a significant contrast in PDE concentration on day 5 between the 18.98 ± 2.43 mg/L of the cured group and the 12.07 ± 2.68 mg/L of the uncured group. ROC curve revealed a higher likelihood of cure in patients when PDE teicoplanin concentration exceeded 15.138 mg/L on day 5 post-dosing. Univariate and multifactorial studies identified 24-h urine volume and the number of daily abdominal dialysis sessions as influential factors in PDE teicoplanin concentration on day 5. A positive correlation was found between 24-h urine volume and PDE teicoplanin concentration, with PDAP patients having urine volume over 537 mL showing significantly higher drug concentrations. Conversely, the number of daily PDAP sessions was negatively correlated with PDE teicoplanin concentrations, indicating that patients with 1~3 daily PDAP sessions had notably higher PDE teicoplanin concentrations compared to those with 4~6 sessions. Therefore, PDAP patients who use intraperitoneal teicoplanin could effectively control infection by monitoring the PDE teicoplanin concentration (>15.138 mg/L) on day 5 after dosing.

Cystic fibrosis (CF) is a genetic monogenic disorder inherited in an autosomal recessive manner, marked by persistent airway infections in the endobronchial region. This condition leads to the gradual development of bronchiectasis and, ultimately, respiratory failure, emerging as the primary cause of mortality in individuals diagnosed with CF. Diagnosis is done depending on the patient's symptoms and lung radiological findings like chest X‐rays and CTs. In younger patients and children, diagnosis becomes difficult due to overlapping symptoms with other diseases such as CF which is a rare genetic disease in our population. Diagnosis of CF usually relies on characteristic symptoms, a family history of CF, and an abnormal sweat chloride test, but in children, low sweat production during testing leads to false negative results. In this case report, a suspected patient with ambiguous respiratory symptoms underwent a comprehensive investigation revealing elevated CRP levels, TLC, and characteristic pulmonary manifestations on chest X‐ray, suggesting cystic fibrosis. Despite negative sweat chloride tests, the patient was analysed for potential candidate SNPs and was also tested for potential CFTR mutations to rule out CF, genetic analysis confirmed the diagnosis. Genetic testing plays a crucial role in diagnosing cystic fibrosis, even when traditional tests are inconclusive. Specific mutations like Δ508 deletion and rs213950 guide personalized treatment. Consanguinity and family history highlight genetic predisposition, while environmental factors may influence symptom onset. Further research is needed to understand these complexities and improve diagnostic and treatment approaches. [ABSTRACT FROM AUTHOR]

Acetochlor is frequently applied to various food crops in agriculture sector, and long-term exposure can cause significant endocrine-disrupting effects in exposed animals including impacts on human health. This study aimed to evaluate the effects of acetochlor on the growth, hematology, serum biochemistry, and histopathological alterations in Japanese quail. Eighty male quail were obtained and divided into four groups (A-D) and given acetochlor orally for the period of 45 days. Group A was served as the control, while groups B, C, and D received 20mg/kg, 30mg/kg, and 40mg/kg acetochlor, respectively. The study found that Japanese quail administered higher doses of acetochlor exhibited reduced frequency of crowing and foam production. The results showed that increased concentrations of acetochlor led to adverse effects on the growth parameters of Japanese quail. Hematology analysis indicated that birds exposed to higher concentrations of acetochlor experienced a significant decrease in red blood cell count, hemoglobin concentration, hematocrit (HCT), mean corpuscular volume (MCV) and mean corpuscular hemoglobin concentration (MCHC), along with a significant increase in white blood cell count compared to the control group. Additionally, higher concentrations of acetochlor led to a significant increase in various serological indices including urea, creatinine, alanine aminotransferase (ALT), and aspartate aminotransferase (AST), while the values of total proteins, albumin, and plasma proteins declined. The histopathology results of treated Japanese quail exposed to higher concentrations of acetochlor showed a range of pathological lesions in the testes, heart, and brain. The study concluded that even low concentrations of acetochlor can cause slight to significant changes in Japanese quail, affecting their physical, hematological, histopathological and serum biochemical parameters.

Background: Cryptococcosis is progressively acknowledged among people, irrespective of the human with or without immunodeficiency virus (HIV). This change in epidemiology has been recorded in recent years, prompting closer examination and a broader understanding of the disease manifestations and risk factors. Methods: The data of cryptococcal infections in China during 11 years were retrospectively analyzed. According to the position of infection, the patients were categorized into the pulmonary infection group and extrapulmonary infection group. The composition of the two groups was compared, and the potential risk factors of disseminated infection were analyzed. Logistic regression was used to analyze the prognostic risk factors of the disease. Results: A total of 165 patients were enrolled. 113 (68.5%) were male, and the age was 47.49 (18–82) years. 101 cases (61.2%) had a normal immune function and 64 cases (38.8%) had impaired immune function. 45 patients had extrapulmonary infection, involving the central nervous system, bone and joint, skin and bloodstream, and 120 patients had simple pulmonary infection. The mortality of the extrapulmonary infection group (48.9%) was significantly higher than that of the pulmonary infection group (0.8%). According to univariate logistic regression analysis, immune status (hazard ratio [HR], 4.476; 95% confidence interval [CI], 1.725–11.618; P = 0.002), infection position ([HR], 113.826; [CI], 14.607-886.967; P < 0.001), white blood cell count, ([HR],1.209;[CI], 1.054–1.386; P = 0.007), hemoglobin ([HR], 0.970; [CI], 0.955–0.986; P < 0.001), platelet count ([HR], 0.993; [CI], 0.987–0.999; P = 0.026), neutrophil percentage ([HR], 1.115; [CI], 1.065–1.168; P < 0.001), lymphocyte percentage ([HR], 0.875; [CI], 0.827–0.927; P < 0.001), neutrophil-to-lymphocyte Ratio (NLR) ([HR], 1.144; [CI], 1.072–1.221; P < 0.001), monocyte percentage ([HR], 0.752; [CI], 0.618–0.915; P = 0.004) were related to the prognosis. Multivariate logistic regression analysis showed that the infection position was remained related to the prognosis with statistical significance ([HR], 0.018; [CI], 0.001–0.384; P = 0.001). Conclusion: Extrapulmonary infection of Cryptococcosis is an important risk factor for prognosis. High levels of neutrophils and NLR, and low levels of lymphocytes and monocytes may lead to disseminated infection of Cryptococcosis. Further studies are needed to reduce the occurrence rate of extrapulmonary infection and mortality. [ABSTRACT FROM AUTHOR]

Background: Gallbladder cysts are rare diseases with very few reported cases, and no clinical or histological definition has been established. Furthermore, cases of giant cysts outside the gallbladder wall are extremely rare. We report a rare case of giant gallbladder cyst with acute cholecystitis. Case presentation: An 85-year-old woman with appetite loss and right lower abdominal pain lasting 2 days presented to our hospital. At first, the patient's abdominal pain was mild to moderate with no fever. Blood tests revealed a white blood cell count of 10,950/mm3, and the C-reactive protein (CRP) level was 14.35 mg/dl. A contrast-enhanced computed tomography (CT) scan of the abdomen revealed a grossly distended gallbladder (14.5 × 14.5 × 8.7 cm) with an incarcerated stone in the cystic duct. The patient was treated by percutaneous transhepatic gallbladder drainage (PTGBD) with 735 ml of drainage fluid. Oral contrast magnetic resonance cholangiopancreatography (MRCP) revealed that gallbladder swelling remained (14.0 × 6.5 cm) 3 days after PTGBD. We performed laparoscopic cholecystectomy 6 days after PTGBD. Because of the severe adhesion around the junction of the cystic and common bile ducts, we performed open cholecystectomy. The resected specimen was 14 × 11 cm in size and consisted of a gallbladder (6 × 7 cm) with a stone (2.4 × 1.8 cm) in the gallbladder and a large cystic lesion (18 × 18 cm) outside the gallbladder wall. The cystic lesion had a wall thickness of 6 to 12 mm and internal septal structures and contained hemorrhagic and necrotic tissue. Histological examination revealed that the specimens showed a mildly swollen gallbladder and a cystic lesion on the outside of the gallbladder wall, adjacent to the gallbladder wall, with wall thickening and inflammation. The cystic lesion suggested gallbladder duplication, gallbladder diverticulum or extension of the Rokitansky-Aschoff sinus (RAS). There was no malignancy. The patient's postoperative course was uneventful, and she was discharged 5 days after the operation. Conclusion: We present a very rare case of giant gallbladder cyst with acute cholecystitis revealed by cholecystectomy. [ABSTRACT FROM AUTHOR]

Background: Stress hyperglycemia is now more common in intensive care unit (ICU) patients and is strongly associated with poor prognosis. Whether this association exists in critically ill patients with cardiogenic shock (CS) is unknown. This study investigated the prognostic relationship of stress hyperglycemia on critically ill patients with CS. Methods: We included 393 critically ill patients with CS from the MIMIC IV database in this study and categorized the patients into four groups based on quartiles of Stress hyperglycemia ratio (SHR). We assessed the correlation between SHR and mortality using restricted cubic spline analysis and Cox proportional hazards models. The primary outcomes observed were ICU mortality and hospitalization mortality. Results: The mean age of the entire study population was 68 years, of which 30% were male (118 cases). There was no significant difference between the four groups in terms of age, gender, BMI, and vital signs (P>0.05). There was an increasing trend in the levels of lactate (lac), white blood cell count (WBC), glutamic oxaloacetic transaminase (AST), glucose and Hemoglobin A1C (HbA1c) from group Q1 to group Q2, with the greatest change in patients in group Q4 (P<0.05) and the patients in group Q4 had the highest use of mechanical ventilation, the longest duration of mechanical ventilation, ICU stay and hospital stay. After adjusting for confounders, SHR was found to be strongly associated with patient ICU mortality, showing a U-shaped relationship. Conclusion: In critically ill patients with CS, stress hyperglycemia assessed by SHR was significantly associated with patient ICU mortality. [ABSTRACT FROM AUTHOR]

Objective: To investigate the clinical efficacy of transumbilical single-incision laparoscopic surgery in the treatment of complicated appendicitis in overweight/obese adolescents. Methods: A retrospective analysis was conducted on the clinical data of 226 adolescent patients with complicated appendicitis who were admitted to our hospital from January 2014 to June 2022. Among them, 102 cases underwent transumbilical single-incision laparoscopic appendectomy as the observation group, and another 124 cases underwent conventional three-port laparoscopic appendectomy as the control group. The surgical time, intraoperative blood loss, duration of incisional pain, postoperative flatus time, length of hospital stay, surgical site infection (SSI), satisfaction with cosmetic result, and occurrence of postoperative complications were compared between the two groups. Results: Both groups completed the surgery smoothly, and there were no statistically significant differences in gender, age, BMI, duration of illness, white blood cell count, and preoperative CRP value between the two groups (P > 0.05). There were no statistically significant differences in surgical time and intraoperative blood loss between the two groups (P > 0.05). However, the observation group had shorter hospital stays, shorter duration of incisional pain, shorter postoperative time to flatus, and lower overall postoperative complication rates compared to the control group, with statistically significant differences (P < 0.05). The observation group had higher satisfaction with cosmetic result compared to the control group, with statistically significant differences (P < 0.05). Both groups were followed up for one year postoperatively, and there were no occurrences of residual appendicitis or severe adhesive intestinal obstruction. Conclusion: When proficiently mastered, the application of transumbilical single-incision laparoscopy in the treatment of complicated appendicitis in overweight/obese adolescents offers advantages such as minimal trauma, rapid recovery, fewer complications, and improved aesthetic outcomes.
