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]

In this study, the protective effects of Panax notoginseng saponins (PNS) against gamma radiation‐induced DNA damage and associated physiological alterations in Swiss albino mice were investigated. Exposure to gamma radiation led to a dose‐dependent increase in cytokinesis‐blocked micronuclei (CBMN) double‐strand DNA breaks (DSBs), dicentric aberrations (DC), formation in peripheral blood mononuclear cells. However, pretreatment with PNS at concentrations of 1, 5, and 10 µg/mL significantly attenuated the frequencies of DC and CBMN in a concentration‐dependent manner. PNS administration before radiation exposure also reduced radiation‐induced DSBs in BL, indicating protection against reactive oxygen species generation and DNA damage. Notably, pretreatment with PNS at 10 µg/mL prevented the overexpression of γ‐H2AX, proteins associated with DNA damage response, in irradiated mice. In addition, in vivo studies showed intraperitoneal administration of PNS (25 mg/kg body weight) for 1 h before radiation exposure mitigated lipid peroxidation levels and restored antioxidant status, countering oxidative damage induced by gamma radiation. Furthermore, PNS pretreatment reversed the decrease in hemoglobin (Hb) content, white blood cell count, and red blood cell count in irradiated mice, indicating preservation of hematological parameters. Overall, PNS demonstrated an anticlastogenic effect by modulating radiation‐induced DSBs and preventing oxidative damage, thus highlighting its potential as a protective agent against radiation‐induced DNA damage and associated physiological alterations. Clinically, PNS will be beneficial for cancer patients undergoing radiotherapy, but their pharmacological properties and toxicity profiles need to be studied. Significance Statement: Radiation induces DNA damage in human cells, posing risks to genomic integrity and cellular function. The study assessed Panax notoginseng saponins (PNS) for protection against gamma radiation‐induced DNA damage in human peripheral lymphocytes and Swiss albino mice. PNS reduced lymphocyte DNA damage markers, lowered lipid peroxidation, restored antioxidants, and maintained hematological parameters. It notably suppressed γ‐H2AX overexpression, indicating DNA damage response modulation. PNS demonstrated potential as an anticlastogenic agent, mitigating radiation‐induced DNA damage and oxidative stress, suggesting its suitability as a protective measure against radiation‐induced physiological changes.

A 61‐year‐old female with diabetes and stage 5 chronic kidney disease on hemodialysis since 3 years via left brachiocephalic arteriovenous fistula presented with uncontrolled sugars, weight loss, and dysphagia. On evaluation, she was found to have an oral thrush with leucocytosis. Initial blood and urine cultures were sterile, and ultrasonography revealed hypoechoic lesions in the left lobe of the liver. She had high‐grade fever followed by seizures on postadmission Day 10. Brain imaging and serum electrolytes were normal. Cerebrospinal fluid analysis was noncontributory, and urine culture revealed Candida non‐albicans with elevated white blood cell counts. She was started on fluconazole; however, her clinical condition deteriorated, with hemodynamic instability. Repeat abdominal computerized tomography revealed increasing hypodense lesions in the left lobe of the liver with elevated beta D glucan levels. Percutaneous drainage of the abscess revealed no fungal elements. In view of clinical deterioration, amphotericin B was started, which resulted in clinical improvement. Clinician should have high index of suspicion for fungal etiology in hemodialysis patients presenting with liver abscess. [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.

Background and Aims: Liver injury is one of the common complications of paraquat (PQ) poisoning, but whether the degree of liver injury is related to patient prognosis is still controversial. This study aimed to investigate whether liver injury was a risk factor for death in PQ‐poisoned patients. Methods: We conducted a retrospective cohort study of PQ‐poisoned patients from the past 10 years (2011–2020) from a large tertiary academic medical centre in China. PQ‐poisoned patients were divided into a normal liver function group (n = 580) and a liver injury group (n = 60). Propensity score matching (PSM) analysis was then performed. Results: A total of 640 patients with PQ poisoning were included in this study. To reduce the impact of bias, dose of PQ, urinary PQ concentration and time from poisoning to hospital admission were matched between the two groups. A 3:1 PSM analysis was performed, ultimately including 240 patients. Compared with the normal liver function group, patients in the liver injury group were older, had a higher R value ([ALT/ULN]/[ALP/ULN]) (p <.001) and had a higher mortality rate. Cox regression analysis showed that there was no significant association between alanine aminotransferase, alkaline phosphatase, total bilirubin levels and hazard of death, but age, PQ dose, creatine kinase isoenzyme, creatine kinase, white blood cell count, neutrophil percentage and lymphocyte percentage were associated with mortality in patients with PQ poisoning. Conclusions: The occurrence of liver injury within 48 h after PQ poisoning was a risk factor for mortality, and such liver injury was likely of a hepatocellular nature. Age, PQ dose, creatine kinase isoenzyme and white blood cell count were positively correlated with mortality, while creatine kinase, percentage of neutrophils and lymphocytes were inversely correlated.

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]

Type 2 diabetes mellitus (T2DM) is not just a local health issue but a significant global health burden, affecting patient outcomes and clinical management worldwide. Despite the wealth of studies reporting T2DM biomarkers, there is an urgent need for a comparative review. This review aims to provide a comprehensive analysis based on the reported T2DM biomarkers and how these are linked with other conditions, such as inflammation and wound healing. A comparative review was conducted on 24 001 study participants, including 10 024 T2DM patients and 13 977 controls (CTL; age 30–90 years). Four main profiles were extracted and analysed from the clinical reports over the past 11 years: haematological (1084 cases vs. 1458 CTL), protein (6753 cases vs. 9613 CTL), cytokine (975 cases vs. 1350 CTL) and lipid (1212 cases vs. 1556 CTL). This review provides a detailed analysis of the haematological profile in T2DM patients, highlighting fundamental changes such as increased white blood cells and platelet counts, accompanied by decreases in red blood cell counts and iron absorption. In the serum protein profile, a reduction in albumin and anti‐inflammatory cytokines was noted along with an increase in globulin levels and pro‐inflammatory cytokines. Furthermore, changes in lipid profiles were discussed, specifically the decreases in high‐density lipoprotein (HDL) and the increases in low‐density lipoprotein (LDL) and triglycerides. Understanding the changes in these four biomarker profiles is essential for developing innovative strategies to create diagnostic and prognostic tools for diabetes management. [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]

Microscopy is currently the gold standard to differentiate BAL fluid (BALF) leukocytes. However, local expertise for microscopic BALF leukocyte differentiation is often unavailable in clinical practice. Can automated flow cytometry be used instead of microscopy to differentiate BALF leukocytes? A new automated flow cytometric method for BALF leukocyte differentiation, using four antibodies (anti-CD45, anti-CD66b, anti-HLA-DR, anti-CD52) given to human BALF in one tube, was developed and prospectively validated in 745 unselected subsequent BALF samples from patients with interstitial lung diseases (455 patients), infectious diseases (196 patients), and other diseases (94 patients). Flow cytometry and traditional microscopy were performed by separate investigators in a double-anonymized fashion. Results were compared using Spearman correlation, Deming regression, and Bland-Altman analysis. There was a strong correlation between flow cytometric and microscopic results regarding macrophage/monocyte, lymphocyte, eosinophil, and neutrophil percentages in BALF (P <.001 for all leukocyte subpopulations). Bland-Altman analyses showed that the mean differences between the methods were ≤ 2% for all four cell types. Flow cytometric results differed less than 20% from microscopic results in more than 95% of all samples. Subgroup analyses confirmed that these results were independent from total leukocyte counts in BALF. We report, to our knowledge, the first validated flow cytometric method for BALF leukocyte differentiation, which can be used in clinical settings where local expertise for microscopic analysis is unavailable and which can be combined easily with lymphocyte surface marker analysis.

The article highlights the advantages of ECIRS, such as high stone-free rates and low complication rates, and emphasizes the importance of thorough preoperative planning and the use of appropriate endoscopes and devices. The authors disclose their potential conflicts of interest and express gratitude to the patient for allowing the publication of her case. [Extracted from the article]

Patients with newly diagnosed hematological malignancies often present with a considerable cellular burden, leading to complications including hyperkalemia. However, pseudohyperkalemia, arising from in vitro cell lysis, can pose challenges in clinical practice. Although pseudohyperkalemia is frequently reported in adult hematological malignancies, its occurrence in pediatric patients is underreported, and its incidence in this demographic remains unclear. We retrospectively reviewed the medical records of pediatric patients who received a new diagnosis of hematological malignancies from 2011 to 2022 at Taichung Veterans General Hospital. Hyperkalemia was defined by a serum or plasma potassium level exceeding 5.5 mEq/L. Pseudohyperkalemia was defined by 1) a potassium decrease of over 1 mEq/L in within 4 h without intervention or 2) the absence of electrocardiography changes indicative of hyperkalemia. Cases with apparent red blood cell hemolysis were excluded. A total of 157 pediatric patients with a new diagnosis of hematological malignancies were included, 14 of whom exhibited hyperkalemia. Among these 14 cases, 7 cases (4.5%) were of pseudohyperkalemia. This rate increased to 21.2% in patients with initial hyperleukocytosis. Pseudohyperkalemia was associated with a higher initial white blood cell count and lower serum sodium level. All episodes of pseudohyperkalemia occurred in the pediatric emergency department, where samples were obtained as plasma, whereas all true hyperkalemia cases were observed in the ordinary ward or intensive care unit, where samples were obtained as serum. Timely recognition of pseudohyperkalemia is crucial to avoiding unnecessary potassium-lowering interventions in pediatric patients with newly diagnosed hematological malignancies.

Coronary artery ectasia (CAE) is a rare vascular phenotype characterized by abnormal dilation of blood vessels and disruption of coronary artery blood flow, which may promote thrombosis and an inflammatory response. We performed a cross-sectional study to investigate the association of white blood cells to mean platelet volume ratio (WMR) with CAE. Consecutive eligible patients (n = 492) were divided into two groups: including 238 patients with CAE and 254 patients in the normal coronary artery (NCA) group. WMR, the systemic immune-inflammation index (SII), and neutrophil-to-lymphocyte ratio (NLR) were found to be significantly associated with CAE in both univariate and multivariate logistic regression analyses. In multivariate analysis, the presence of WMR was associated with CAE (the odds ratios (OR) = 1.002, 95% CI: 1.001–1.003, P <.001). In the ROC analysis, the statistics (Z-values) of WMR vs SII and WMR vs NLR were 2.427 and 2.670 and were statistically significant (P =.015 and P =.008), indicating that WMR was superior to SII and NLR in distinguishing WMR. The optimal cut-off value was calculated from the point of maximal sensitivity and specificity by using Youden's index, which was determined to be 635.50. WMR has the potential to be a cost-effective tool to monitor CAE. [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.

Systemic lupus erythematosus (SLE) affects many populations. This study aims to develop a predictive model and create a nomogram for assessing the risk of end-stage renal disease (ESRD) in patients diagnosed with SLE. Data from electronic health records of SLE patients treated at the Affiliated Hospital of North Sichuan Medical College between 2013 and 2023 were collected. The dataset underwent thorough cleaning and variable assignment procedures. Subsequently, variables were selected using one-way logistic regression and lasso logistic regression methods, followed by multifactorial logistic regression to construct nomograms. The model's performance was assessed using calibration, receiver operating characteristic (ROC), and decision curve analysis (DCA) curves. Statistical significance was set at P < 0.05. The predictive variables for ESRD development in SLE patients included anti-GP210 antibody presence, urinary occult blood, proteinuria, white blood cell count, complement 4 levels, uric acid, creatinine, total protein, globulin, glomerular filtration rate, pH, specific gravity, very low-density lipoprotein, homocysteine, apolipoprotein B, and absolute counts of cytotoxic T cells. The nomogram exhibited a broad predictive range. The ROC area under the curve (AUC) was 0.886 (0.858–0.913) for the training set and 0.840 (0.783–0.897) for the testing set, indicating good model performance. The model demonstrated both applicability and significant clinical benefits. The developed model presents strong predictive capabilities and considerable clinical utility in estimating the risk of ESRD in patients with SLE. [ABSTRACT FROM AUTHOR]

Purpose: To evaluate the utility of cervical cultures in the diagnosis and management of postpartum endometritis. Methods: A retrospective study was conducted on 1069 cervical cultures collected from postpartum women with suspected endometritis between 2011 and 2021. Patient demographics, obstetric history, clinical parameters, and culture results were analyzed. Microorganisms were categorized into five groups based on species and virulence. Statistical analysis was performed to identify associations between risk factors, pathogens, and disease severity. Results: The positivity rate for distinct microorganisms in cervical cultures was 33.1%. Escherichia coli (10.8%) and Group B Streptococcus (7.5%) were the most common isolates. Prolonged labor duration and prolonged rupture of membranes were associated with Enterobacterales infections. Elevated white blood cell count was linked to Enterobacterales and beta-hemolytic Streptococci, while the former were also associated with higher rate of postpartum clinic visit. No significant differences in disease severity were found between other microorganism groups. Conclusion: The study suggests that while cervical cultures can identify potential pathogens in postpartum endometritis, their clinical utility is questionable due to the polymicrobial nature of the disease and the isolation of commensal microorganisms. The lack of significant differences in disease severity across various microorganism groups raises questions regarding the contribution of distinct bacterial identification in endometritis management.

Isolated psychiatric symptoms can be the initial symptom of pediatric anti- N -methyl-d-aspartate (NMDA) receptor autoimmune encephalitis (pNMDARE). Here we report on the prevalence of isolated psychiatric symptoms in pNMDARE. We also assess whether initial neurodiagnostic tests (brain magnetic resonance imaging [MRI], electroencephalography [EEG], and/or cerebrospinal fluid [CSF] white blood cell count) are abnormal in children with isolated psychiatric symptoms and pNMDARE. This multicenter retrospective cohort study from CONNECT (Conquering Neuroinflammation and Epilepsies Consortium) from 14 institutions included children under age 18 years who were diagnosed with pNMDARE. Descriptive statistics using means, medians, and comparisons for continuous versus discrete data was performed. Of 249 children included, 12 (5%) had only psychiatric symptoms without other typical clinical features of autoimmune encephalitis at presentation. All but one (11 of 12 = 92%) had at least one abnormal finding on initial ancillary testing: eight of 12 (67%) had an abnormal EEG, six of 12 (50%) had an abnormal MRI, and five of 12 (42%) demonstrated CSF pleocytosis. The single patient with a normal MRI, EEG, and CSF profile had low positive CSF NMDA antibody (titer of 1:1), and symptoms improved without immunotherapy. Isolated first-episode psychiatric symptoms in pNMDARE are uncommon, and the majority of children will exhibit additional neurodiagnostic abnormalities. Delaying immunotherapy in a child with isolated psychiatric symptoms and normal neurodiagnostic testing may be warranted while awaiting confirmatory antibody testing. [ABSTRACT FROM AUTHOR]

Legal restrictions and consumer trends are contributing to the growing movement for fish welfare. Therefore, the aquaculture sector is a means of reducing animal stress and enhancing physiological state, which raises financial profits. Feed additives have therefore been suggested as possible dietary stress alleviation. In this trend, a 75-day feeding trial was conducted to evaluate the effects of three organic acids (formic acid (FA), lactic acid (LA), and commercial organic acids mix (COM)) as dietary additives in Nile tilapia (Oreochromis niloticus) reared under a stressful condition (unchanged water). Fish (weighing 3.95 ± 0.05 g) were randomly housed into eight groups (n = 210 fish/group; 70 fish/replicate; 3 replicates/group). The first (negative control) and second (positive control) groups were fed a basal diet without additives and with water exchange at 20% of the water volume every 2 days for the first group and without water exchange for the second. The other six groups (FA1, FA2, LA1, LA2, COM1, and COM2) were fed basal diets supplemented with OAs at two doses (1 and 2%) without water exchange during the trial. The results revealed that fish kept without water exchange (positive control) had the highest level of water-unionized ammonia and nitrite and a marked decline in growth performance (weight gain and specific growth rate). The unchanged water induced substantial decreases in the hematological profile (white and red blood cell count, hemoglobin value, and hematocrit %), protein profile indices (total protein, albumin, and globulin), and antioxidant-immune response (superoxide dismutase, catalase, lysozyme, and total immunoglobulin M). In addition, the biochemical indices (glucose, creatinine, urea, alanine aminotransferase, and aspartate aminotransferase) and lipid peroxide (malondialdehyde) were substantially increased in the positive control group. In addition to that, marked and severe histopathological alteration in the gills, liver, and intestine including hyperplasia, hemorrhage, and degenerative and necrotic changes that were associated with desquamation and sloughing were obvious in the PC group. Dietary LA1 significantly enhanced (P < 0.05) the overall measured indices; meanwhile, the dietary FA and COM recorded the worst results. Overall, our findings demonstrate that the unchanged water negatively affected the growth and physiological functions of Nile tilapia. Dietary incorporation of organic acids did not protect the fish from these hazards except the LA (1%). The latter can reduce nitrogenous compounds, enhance immune response, and alleviate these alterations for the sustainable aquaculture industry. [ABSTRACT FROM AUTHOR]

Objective: Evaluate the microbial yield and factors predicting culture positivity for image-guided arthrocentesis of suspected septic sternoclavicular (SC) arthritis. Materials and methods: An electronic health record search identified image-guided SC joint aspirations for suspected septic arthritis. Data was extracted by retrospective chart review including patient demographics, procedure characteristics, pre-procedure lab testing, joint culture results, final SC joint diagnoses and any effect of positive synovial cultures on subsequent antibiotic therapy. Factors associated with positive joint fluid cultures were assessed using a Chi-squared test for categorical predictors and logistic regression for continuous predictors. Results: A total of 31 SC arthrocenteses met inclusion criteria with most (81%) performed using ultrasound guidance. Synovial fluid was successfully aspirated in 19/31 (61%) of cases, and in all other cases lavage fluid was successfully obtained. Synovial cultures were positive in 9/31 (29%) of cases. A final diagnosis of septic arthritis was assigned to 20/31 cases (65%) in which 9/20 (45%) had positive synovial cultures. There was no statistically significant association between synovial culture positivity and risk factors for septic arthritis, positive blood cultures, pre-aspiration antibiotics and whether synovial fluid or lavage fluid was cultured. Serum white blood cell count (WBC) and erythrocyte sedimentation rate (ESR) demonstrated statistically significant positive correlation with positive synovial cultures. Conclusion: Arthrocentesis is effective for microbial speciation in SC septic arthritis, and diagnostic yield may be increased with lavage when encountering a dry tap. Normal serum WBC and ESR values indicate an extremely low likelihood of positive synovial cultures. [ABSTRACT FROM AUTHOR]

Background: Levamisole is less expensive and has a better toxicity profile compared to other steroid sparing agents used in nephrotic syndrome. It has a plasma half-life of 2.0 to 5.6 hours, but is conventionally administered on alternate days. We aimed to assess whether daily levamisole is safe and more effective than standard alternate-day therapy in maintaining remission in children with frequently relapsing or steroid-dependent nephrotic syndrome (FR/SDNS). Methods: An open-label randomized controlled trial was conducted in children with FR/SDNS. Group A received daily while Group B received alternate-day levamisole (2–3 mg/kg/dose) for 12 months. Prednisolone was tapered off by 3 months. Patients were monitored for relapses, further steroid requirement, and adverse effects. Results: A total of 190 children with FR/SDNS (94 in Group A and 96 in Group B) were analyzed. Sustained remission for 12 months was observed in 36% of Group A and 27% of Group B patients (p = 0.18). Numbers completing 12 months in the study were 67% in Group A and 56% in Group B (p = 0.13). Time to first relapse, persistent FR/SDNS, and withdrawal due to poor compliance were statistically similar in both groups, while relapse rate and cumulative steroid dosage were significantly lower in Group A compared to Group B (p = 0.03 and p = 0.02, respectively). The incidence of adverse effects was comparable in both groups, with reversible leucopenia and hepatic transaminitis being the commonest. Conclusions: Daily levamisole therapy was not superior to alternate-day therapy in maintaining sustained remission over 12 months. Nevertheless, relapse rate and cumulative steroid dosage were significantly lower without increased adverse effects.

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.

Background: In October 2023, our hospital confirmed a case of a patient with HIV with concurrent infection with Nocardia brasiliensis. A patient with HIV developed a lump on the surface of the dorsum of his left hand without any obvious cause. He used a nail clipper to trim it. Due to improper disinfection and treatment methods, the condition worsened, and he subsequently sought medical attention at our hospital. A series of clinical laboratory tests were conducted based on the patient's medical history, symptoms, and signs. Based on the test results, a reasonable clinical treatment plan was adopted, ultimately achieving satisfactory treatment outcomes for the patient. Methods: Clinical implementation of pus bacterial culture and identification (matrix-assisted laser desorption/ionization time-of-flight mass spectrometry, MALDI-TOF MS), serum anti HIV detection, and Treponema pallidum antibody detection. Additional related auxiliary examinations: blood routine, liver function, kidney function, CRP, electrolytes. Results: Blood routine and CRP (venous blood): White blood cell count 16.00 x 109/L, total number of lymphocytes 3.73 x 109/L, total monocyte count 1.66 x 109/L, total number of neutrophils 10.37 x 109/L, total number of basophils 0.10 x 109/L, average platelet volume 8.8 fL, whole blood high-sensitivity C-reactive protein 46.44 mg/L, urine routine: protein+-. Liver function test: Albumin 37.7 g/L, aspartate aminotransferase 55.5 U/L, alanine aminotransferase 63.7 U/L, blood lipid test: triglycerides 2.22 mmol/L, high-density lipoprotein cholesterol 0.77 mmol/L, coagulation function test: fibrinogen test 5.69 g/L, lymphocyte subgroup analysis: T4/T8 cell ratio 0.78, total mature T cell count 2.501 x 109/L, T8 cell count 1.351 x 109/L, B cell count 0.574 x 109/L. Serum pathogen test: anti HIV positive, Treponema pallidum antibody 214.70 IU/mL, unheated serum reactive hormone test positive (1:8). Gram staining of pus: a large number of Gram positive bacteria were found, arrange in a branching form, weak acid-fast staining: positive, pus culture and bacteria identified (MALDI-TOF MS): Nocardia brasiliensis. Clinical treatment includes trimethoprim/sulfamethoxazole 800 mg/160 mg po q12 hours, local wet compress with Baiduobang ointment, and abscess incised and drained. Seven days later, the patient had a circular ulcer on the left back without any new pustules. Slightly elevated skin temperature, no tenderness, and no purulent or bloody secretions. His condition had improved and he was discharged. Follow up infectious disease specialist hospitals treat HIV, syphilis, and other related diseases. Conclusions: Patients with HIV are prone to various types of infections, even rare bacteria, as their immune function decreases. At present, there are few reports about a patient with HIV with concurrent infection with Nocardia brasiliensis. This case can provide reference for clinical diagnosis and treatment of related diseases in the future. In addition, with the popularity of new identification methods such as mass spectrometry, laboratories should pay attention to traditional staining methods and use microscopes to detect pathogens.

The study aimed to investigate the impact of administering the antibiotic florfenicol (FFC) through dietary means on Oreochromis niloticus. The experiment involved exposing the fish to FFC at doses 0–10 times the therapeutic dose of 15 mg/kg biomass per day for 10 consecutive days. The group receiving the therapeutic dose showed 100% survival on the 10th day of dosing. Histological analysis revealed dose‐dependent changes in the spleen, including an increase in sinusoidal space, splenic necrosis, white pulp proliferation, splenitis, and red pulp hemorrhages. Additionally, there was an exponential rise in leukocyte counts accompanied by a significant decrease in erythrocyte counts, indicating the development of anemia due to FFC. The observed splenic histological damage, along with increased erythrophagia, erythro‐membrane breakage, and poikilocytosis, highlighted the splenotoxic and hemotoxic effects of FFC at higher doses. Importantly, these toxic effects showed considerable reduction upon discontinuation of FFC dosing. The study emphasized the need to consider FFC‐induced splenotoxic and hemotoxic outcomes in O. niloticus during its application in aquaculture. [ABSTRACT FROM AUTHOR]

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]

The performance of synovial fluid biomarker D-lactate to diagnose septic arthritis (SA) and differentiate it from crystal-induced arthritis (CA), other non-infectious rheumatic joint diseases (RD) and osteoarthrosis (OA) was evaluated.Consecutive adult patients undergoing synovial fluid aspiration due to joint pain were prospectively included in different German and Swiss centers. Synovial fluid was collected for culture, leukocyte count and differentiation, detection of crystals, and D-lactate concentration. Youden’s J statistic was used to determine optimal D-lactate cut-off value on the receiver operating characteristic (ROC) curve by maximizing sensitivity and specificity.In total 231 patients were included. Thirty-nine patients had SA and 192 aseptic arthritis (56 patients with OA, 68 with CA, and 68 with RD). The median concentration of synovial fluid D-lactate was significantly higher in patients with SA than in those with OA, CA, and RD (p<0.0001, p<0.0001 and p<0.0001, respectively). The optimal cut-off of synovial fluid D-lactate to diagnose SA was 0.033 mmol/L with a sensitivity of 92.3 % and specificity of 85.4 % independent of previous antimicrobial treatment. Sensitivity and specificity of synovial fluid leukocyte count at a cut-off of 20,000 cells/µL was 81.1 % and 80.8 %, respectively.Synovial fluid D-lactate showed a high performance for diagnosing SA which was superior to synovial fluid leukocyte count. Given its high sensitivity and specificity, it serves as both an effective screening tool for SA and a differentiator between SA and RD, especially CA. [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.

A smear review is typically made in flagged differential counts performed with hematology analyzers although the clinical value of such reviews is uncertain. Therefore, we evaluated the differences in differential counts between Sysmex XN-9000 and a smear review in flagged samples. Furthermore, the clinical value of blasts identified was investigated.Data on all differential counts performed in a two-year period were identified at two laboratories. In patients with blasts, the electronic health record was reviewed. Agreement between automated and manual differential counts was evaluated by Bland-Altman plots. Concordance between the two methods categorized according to reference intervals was evaluated and adjusted for irrelevant non-concordance caused by random analytical error.In total, 5,500 flagged differential counts were identified from 4,092 patients. A good agreement between the automated and manual differential count was found for all cell types (−0.480 × 109/L to 0.297 × 109/L). The concordance between the two methods was excellent for all cell types, except for monocytes (82 %) where the automated estimates were higher than the manual in 19 % of samples. Blasts were identified in 241 (1 %) of smear reviews. Acute leukemia was diagnosed in 13 (5 %) patients, and only in one patient contributed the detection of blasts to the suspicion of acute leukemia.Our findings indicate that routine smear review of all flagged samples do not contribute with additional, significant information. After local validation and dialogue with clinical departments, such reviews may potentially be omitted to increase cost-effectiveness and reduce turn-around-time. [ABSTRACT FROM AUTHOR]

Pneumonia is a common postoperative complication in patients with aneurysmal subarachnoid hemorrhage (aSAH), which is associated with poor prognosis and increased mortality. The aim of this study was to develop a predictive model for postoperative pneumonia (POP) in patients with aSAH. A retrospective analysis was conducted on 308 patients with aSAH who underwent surgery at the Neurosurgery Department of the First Affiliated Hospital of Soochow University. Univariate and multivariate logistic regression and lasso regression analysis were used to analyze the risk factors for POP. Receiver operating characteristic (ROC) curve, calibration curve, and decision curve analysis (DCA) were used to evaluate the constructed model. Finally, the effectiveness of modeling these six variables in different machine learning methods was investigated. In our patient cohort, 23.4% (n = 72/308) of patients experienced POP. Univariate, multivariate logistic regression analysis and lasso regression analysis revealed age, Hunt-Hess grade, mechanical ventilation, leukocyte count, lymphocyte count, and platelet count as independent risk factors for POP. Subsequently, these six factors were used to build the final model. We found that age, Hunt-Hess grade, mechanical ventilation, leukocyte count, lymphocyte count, and platelet count were independent risk factors for POP in patients with aSAH. Through validation and comparison with other studies and machine learning models, our novel predictive model has demonstrated high efficacy in effectively predicting the likelihood of pneumonia during the hospitalization of aSAH patients.

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]
