The Role of Peripheral Blood Inflammation Indices in Patients with a Diagnosis of Endometrial Hyperplasia and Cancer

Purpose: Endometrial cancer (EC) is an important problem with its increasing incidence, especially in developed countries. There is no generally accepted screening program yet. The management of endometrial hyperplasia (EH), which is the most important risk factor, is complex because it is an invasive process. Methods: A retrospective study was conducted with a total of 72 patients. Patients between the ages of 35-65 with abnormal uterine bleeding, and increased endometrial thickness on transvaginal sonography were evaluated with pathology results. Sociodemographic characteristics of the patients and laboratory values at hospital admission were obtained from hospital records. White blood cells (WBC), neutrophils, lymphocytes, monocytes, eosinophils, basophils, and thrombocyte counts (x10⁹/L); plateletcrit (%), hemoglobin (Hb) (g/dL), and hematocrit (Htc) (%) values were recorded. Neutrophil lymphocyte ratio (NLR), monocyte lymphocyte ratio (MLR), and thrombocyte lymphocyte ratio (TLR) were obtained. Systemic immune-inflammation index (SII), systemic inflammation response index (SIRI) and pan-immune-inflammation value (PIV) were obtained. Results: Thirty-seven patients diagnosed with EH and 35 patients diagnosed with endometrial malignancy were included. The mean age of the EH was 45.5 years and the mean age of the malignant group was 50.5 years (p=0.027). The sociodemographic characteristics of the patients were found to be similar. There was no significant difference in complete blood count parameters between two groups. Mean values of NLR were 2.33 and 2.52 in EH and EC groups, respectively, p = 0.448. Mean values of MLR were 0.20 and 0.21, respectively, p = 0.498. Mean values of TLR were 0.16 and 0.15, respectively, p = 0.811. Mean values of SII were 720.1 and 812.4 (x10⁹/L), respectively, p = 0.456. Mean values of SIRI were 943.1 and 1095.6 (x10⁹/L), respectively, p = 0.257. Mean values of PIV were 312753.6 and 352975.1 (x10⁹/L), respectively, p = 0.514. Conclusion: Peripheral blood inflammation indices have recently been used in cancer diagnosis and follow-up. We did not find any statistically significant differences in the investigated parametrers between the EH and EC patient groups. Close follow-up is necessary in the presence of additional risk factors in women with EH.

The Role of Inflammatory Markers in Distinguishing Endometrial Polyp: Single Center Results

Objective: To investigate the role of inflammatory markers in predicting the presence of endometrial polyps in patients undergoing endometrial sampling due to abnormal uterine bleeding. Methods: The pathology results of patients who presented to Akçakoca State Hospital with abnormal uterine bleeding and underwent endometrial sampling between May 2023 and July 2023 were retrospectively examined. The demographic characteristics of the patients, platelet-lymphocyte, neutrophil-lymphocyte and lymphocyte-monocyte ratios and systemic immune inflammation index were calculated. Patients were categorized into endometrial polyps and other benign pathologies according to the pathological diagnosis. Malignant and premalignant lesions were not included in the study. The examination results and inflammatory markers were compared between these two groups. Results: 89 patients were included in the study. While the pathological finding in 38 patients was an endometrial polyp, other benign pathologies were found in 51 patients. No significant difference was found in terms of hemoglobin, hematocrit, lymphocytes, monocytes, platelets, neutrophils and PDW variables in patients with endometrial polyps (p>0.05). PLR (platelet-to-lymphocyte ratio) and SII (systemic immune-inflammatory index) were significantly higher in the endometrial polyp group compared to other benign pathologies (p

Osmotic demyelination syndrome: revisiting the diagnostic criteria through two fatal cases

BackgroundOsmotic Demyelination Syndrome (ODS) encompasses Central Pontine Myelinolysis and Extrapontine Myelinolysis, both of which are serious neurological conditions linked to the overly rapid correction of hyponatremia. Despite growing evidence, the exact etiology of ODS remains incompletely understood. The present paper describes two case studies, aiming to provide a comprehensive overview of the pathological findings and clinical outcomes associated with ODS.Case presentationCase #1. A 74-year-old woman was admitted to the emergency department following a head trauma caused by a loss of consciousness. Initial laboratory tests revealed severe hyponatremia (sodium level of 101 mmol/L) and hypokalemia (potassium level of 2.9 mmol/L). The patient underwent corrective therapy with saline and potassium chloride. Despite the correction of electrolyte imbalances, the patient developed a hyperintense lesion in the median portion of the pons on T2-fluid-attenuated inversion recovery (FLAIR) MRI sequence 14 days post-treatment, consistent with ODS. The patient’s condition deteriorated, leading to irreversible coma and status epilepticus, culminating in death 32 days after admission. Case #2. An 81-year-old woman with a medical history of hypothyroidism, hypertension, major depression, and stage 3 chronic kidney disease presented with mild gait disturbances. Subsequent testing revealed severe hyponatremia (sodium level of 100 mmol/L). Following an initial clinical improvement due to sodium correction, the patient’s condition worsened, with symptoms progressing to confusion, lethargy, and eventually, ODS. Dermatological manifestations, including blistering lesions and facial edema, appeared as the condition advanced. The patient succumbed to irreversible coma 47 days after admission.ConclusionODS traditionally carried a poor prognosis, with high mortality rates and diagnoses often made postmortem. However, recent advances in understanding the pathophysiology, along with improvements in diagnostic techniques such as MRI and intensive care treatments, have led to earlier identification, treatment, and recognition of milder forms of the syndrome. Despite these advancements, ODS remains a critical condition with significant risks, particularly following the rapid correction of severe hyponatremia.

Outcomes of Bridging Therapy in Liver Transplantation for Hepatocellular Carcinoma

Background: Liver transplantation (LT) is a method for treating hepatocellular carcinoma (HCC) with satisfactory outcomes. One of the novel methods for predicting LT outcomes is the Metroticket 2.0 model. The disease in patients initially within the Milan criteria (MC) may progress while on a transplantation waitlist; thus, various transplantation bridging therapy (BT) methods are proposed for patients to stay within the MC and optimize the LT outcome. Methods: We performed a retrospective analysis of patients who underwent LT for HCC at an oncological and transplantation center in northern Poland. Patients who underwent (n = 10) or did not undergo (n = 11) BT were included. The primary endpoints of the study were mortality among the patients, HCC recurrence, and Metroticket 2.0 scores based on LT qualification results and explant pathology outcomes. The median follow-up length was 44.03 months. Results: Patients who underwent BT had significantly lower Metroticket 2.0 scores and greater AFP concentrations at baseline. At LT, there was no significant difference in Metroticket 2.0 scores or AFP concentrations between the groups. Explant Metroticket 2.0 scores were significantly lower in patients who received BT. A complete pathologic response was achieved in 30.0% of patients who underwent BT. The recurrence-free survival rates were 100% and 90.91% in patients who underwent and did not undergo BT, respectively. Overall survival was 80.0% and 81.81% in patients who underwent and did not undergo BT, respectively. Conclusions: BT should be considered only as a means of remaining within the LT criteria. Routine BT does not appear to be justified for LT patients.

ISG15 Drives Immune Pathology and Respiratory Failure during Systemic Lymphocytic Choriomeningitis Virus Infection.

ISG15, an IFN-stimulated gene, plays a crucial role in modulating immune responses during viral infections. Its upregulation is part of the host's defense mechanism against viruses, contributing to the antiviral state of cells. However, altered ISG15 expression can also lead to immune dysregulation and pathological outcomes, particularly during persistent viral infections. Understanding the balance of ISG15 in promoting antiviral immunity while avoiding immune-mediated pathology is essential for developing targeted therapeutic interventions against viral diseases. In this article, using Usp18-deficient, USP18 enzymatic-inactive and Isg15-deficient mouse models, we report that a lack of USP18 enzymatic function during persistent viral infection leads to severe immune pathology characterized by hematological disruptions described by reductions in platelets, total WBCs, and lymphocyte counts; pulmonary cytokine amplification; lung vascular leakage; and death. The lack of Usp18 in myeloid cells mimicked the pathological manifestations observed in Usp18-/- mice and required Isg15. Mechanistically, interrupting the enzymes that conjugate/deconjugate ISG15, using Uba7-/- or Usp18C61A mice, respectively, led to accumulation of ISG15 that was accompanied by inflammatory neutrophil accumulation, lung pathology, and death similar to that observed in Usp18-deficient mice. Moreover, myeloid cell depletion reversed pathological manifestations, morbidity, and mortality in Usp18C61A mice. Our results suggest that dysregulated ISG15 production and signaling during persistent lymphocytic choriomeningitis virus infection can produce lethal immune pathology and could serve as a therapeutic target during severe viral infections with pulmonary pathological manifestations.

Efficacy and Predictive Factors Analysis of Androgen Deprivation Plus Novel Hormone Therapy as Neoadjuvant Treatment for High-Risk Prostate Cancer.

This investigation explored the clinical features, pathological outcomes, and biochemical recurrence (BCR) duration among high-risk prostate cancer (HRPC) patients who have undergone neoadjuvant therapy (NAT) in combination with radical prostatectomy (RP) and pelvic lymph node dissection (PLND). Additionally, we identified prognostic indicators that discern pathological complete response (pCR) or minimal residual disease (MRD) and BCR. In total, we examined 76 HRPC patients, who received NAT with either androgen deprivation therapy (ADT) plus apalutamide or ADT plus abiraterone, with subsequent RP and PLND. We conducted a genetic evaluation of patients receiving neoadjuvant apalutamide. Additionally, patient pathological outcomes, circulating prostate-specific antigen (PSA) response rates, and BCR duration were analyzed. Lastly, we employed uni- and multivariate analyses to screen for prognostic factors that govern pCR or MRD and BCR duration. Patient median age and median PSA at presentation were 69 years (IQR: 66-73), and 47.6 ng/mL (IQR: 24.1-105.75), respectively. We observed marked changes in pCR or MRD rates between the two cohorts. In particular, the ADT plus apalutamide cohort (51.5%) exhibited enhanced rates relative to the ADT plus abiraterone cohort (25.6%) (p = 0.03). The median BCR duration was substantially prolonged among neoadjuvant apalutamide cohort relative to the neoadjuvant abiraterone cohort (261 days vs. 76 days, p = 0.04). Using multivariate analysis, we revealed that the postintervention pre-RP PSA content (≤ 0.1 ng/mL vs. > 0.1 ng/mL) remained a substantial stand-alone indicator of pCR or MRD (odds ratio: 10.712, 95% CI: 2.725-42.105, p < 0.001). Furthermore, supplemental analyses revealed that the ADT plus apalutamide cohort exhibited an augmented serum response rate, which, in turn, reduced the post-intervention pre-RP PSA content. Based on our genetic profiling of the neoadjuvant apalutamide cohort demonstrated high-frequency deleterious changes in the AR axis (30.3%), followed by TP53 mutations (15.15%). Patients with defective AR axis experienced a remarkably shorter median BCR duration relative to patients with other or no genetic alterations (52.5 days vs. 286 and 336 days, respectively, p < 0.0001). Furthermore, using multivariate analysis, we demonstrated that achieving pCR or MRD (hazard ratio [HR]: 0.170, 95% CI: 0.061-0.477, p < 0.001) and presence of defective AR signaling (HR: 11.193, 95% CI: 3.499-35.806, p < 0.001) were strong stand-alone indicators of BCR. Herein, we demonstrated the superior performance of ADT plus apalutamide in achieving pCR or MRD and in extending BCR duration among HRPC patients. Post-intervention pre-RP PSA content as well as genetic shifts, especially in the AR axis, are critical indicators of patient pathological and clinical outcomes. These findings highlight the significance of genetic testing and PSA content monitoring in treating HRPC patients.

Tumor regression after neoadjuvant hormonal therapy in high risk prostate cancer: pathological outcomes from a randomized phase II trial.

High-risk localized prostate cancer (HRLPC) commonly progresses to metastatic disease after local treatment. Neoadjuvant androgen deprivation therapy (nADT) before radical prostatectomy (RP) has recently been suggested to improve early oncological outcomes in HRLPC. We aimed to perform an exploratory analysis of the pathological outcomes from a prospective trial testing nADT before RP. Prospective, single-centered, phase II, randomized trial performed between October 2018 and July 2021. Random assignment (1:1) for nADT modalities: goserelin (10.8mg) plus abiraterone acetate (1000mg/d) plus prednisone (5mg/d), with or without apalutamide (240mg/d) for 12 weeks, followed by RP (within 30 days) and extended lymph node dissection. Baseline clinical and pathological variables were assessed in needle biopsies before nADT. Tumor regression was histologically evaluated in surgical specimens using the residual cancer burden index (RCB). Sixty-two patients reached the surgical phase. Good response (RCB ≤ 0.25cm³) was achieved in 14 patients (22.5%). Overall stage migration rate between baseline status (MRI before nADT) and final status (after surgery) was 27.4%. Late stage detection (high tumor burden, perineural invasion) and altered PTEN/ERG immunostatus showed significant association with poor response in univariate analysis. Higher baseline tumor burden was the only independent factor related to poor response in multivariate analysis. There are subgroups of patients, such as those with low baseline cancer burden and PTEN/ERG wild-type status, more likely to achieve good response with nADT. In the case of long term oncological benefit to be proven, nADT might be an additional therapeutic resource for these patients.

Survival Outcomes According to NCCN Criteria for Resection Following Neoadjuvant Therapy for Patients with Localized Pancreatic Cancer.

This study aimed to assess the prognostic value of the National Comprehensive Cancer Network (NCCN) criteria for resection following neoadjuvant therapy for patients with localized pancreatic ductal adenocarcinoma (PDAC). This retrospective single-center study assessed 193 consecutive patients with localized PDAC (104 males and 89 females; mean age, 61.1 ± 9.4 years) who underwent neoadjuvant therapy followed by surgery between January 2010 and March 2021. Combined resectability and carbohydrate antigen (CA) 19-9 evaluation before and after neoadjuvant therapy was used to determine whether patients were eligible for resection according to the NCCN criteria. Post-surgical overall survival (OS), recurrence free survival (RFS), and pathologic results were evaluated and compared between patients considered eligible according to the NCCN criteria and those considered ineligible. Preoperative factors associated with better OS and RFS also were investigated. Of the 193 patients, 168 (87.0 %) were eligible for resection according to the NCCN criteria. The patients eligible according to the NCCN criteria showed marginally longer OS than those considered ineligible (p = 0.056). After adjustment of variables, meeting the NCCN criteria for resection was an independent predictor of better OS (hazard ratio, 0.57; 95 % confidence interval, 0.34-0.96; p = 0.034). The two groups had similar RFS. Lower T-staging (T2 or less) and less lympho-vascular invasion and peri-neural invasion were noted in the patients who met the NCCN criteria (p ≤ 0.045). The patients eligible for resection according to the NCCN criteria showed a trend toward longer OS and better pathologic results than the patients considered ineligible.

A Multimodal Deep Learning Nomogram for the Identification of Clinically Significant Prostate Cancer in Patients with Gray-Zone PSA Levels: Comparison with Clinical and Radiomics Models

ObjectiveTo establish a multimodal deep learning nomogram for predicting clinically significant prostate cancer in patients with grey-zone PSA levels. MethodsThis retrospective study enrolled 303 patients with pathological results between January 2018 and December 2022. Clinical variables and the PI-RADS v2.1 score were used to construct a clinical model. Radiomics and deep learning features from bp-MRI were used to develop a radiomics model with SVM and a deep learning model, respectively. A hybrid fusion approach was used to integrate the multimodal data and construct combined models (Comb.Rad.model and Comb.DL.model). The robustness of the radiomics model with XGBoost was validated and compared. Model efficacy was assessed through ROC curve and decision curve analysis. A nomogram was developed based on the best-performing model. ResultsThe clinical model had AUCs of 0.845 and 0.779 in the training and testing set. The radiomics model with SVM and the deep learning model achieved AUCs of 0.825 and 0.933 in the training set and 0.811 and 0.907 in the testing set, respectively. The diagnostic performance of the combined models was significantly improved, with Comb.DL.model having a higher AUC than Comb.Rad.model in both the training (0.986 vs. 0.924, P = 0.008) and testing (0.965 vs. 0.859, P = 0.005) set. The diagnostic efficiency of both the radiomics model and Comb.Rad.model with XGBoost were comparable to that of SVM, confirming the robustness of the established model. ConclusionThe integrated nomogram combining deep learning features, PI-RADS score, and clinical variables significantly outperformed the traditional radiomics and clinical models.

Effects of radial artery spasm prophylaxis on intracoronary vasomotor responses during acetylcholine spasm provocation testing

BackgroundInvasive coronary angiography via the radial approach is commonly performed following radial artery spasm prophylaxis (RASP). It is however unknown, whether RASP influences the results of coronary spasm provocation testing performed after diagnostic angiography. We aimed to investigate the effects of RASP on vasomotor responses during intracoronary acetylcholine (ACh) testing. MethodsWe retrospectively screened 372 consecutive patients (51 % female, mean age 61 ± 11 years) with angina and non-obstructive coronary arteries, who underwent intracoronary provocation with ACh according to a standardized protocol. During testing, dose-dependent clinical discomfort and concomitant ischemic electrocardiographic changes were recorded in addition to visual reductions of epicardial lumen diameters. Of these patients, 156 (42 %) received RASP (i.e. 200 μg nitroglycerin and 2.5 mg verapamil), while no RASP was administered in 216 (58 %) patients. Both groups were compared regarding age, sex, cardiovascular risk factors and ACh-test results. ResultsACh provocation testing revealed a pathological test result in 71 patients (46 %) with RASP and 103 patients (48 %) without (p = 0.752) [epicardial spasm: in 20 patients (28 %) with RASP and 42 patients (41 %) without (p = 0.120); microvascular spasm: in 51 patients (72 %) with RASP and 61 patients (59 %) without (p = 0.362)]. Overall, RASP did not significantly alter coronary artery vasomotor responses, neither regarding the frequency (p = 0.752) or type of coronary spasm (microvascular vs. epicardial; p = 0.108) nor regarding the ACh dose leading to spasm (p = 0.151). ConclusionsRASP does not significantly affect coronary vasomotor responses to ACh, suggesting that radial artery spasm prophylaxis can be routinely administered even in patients in whom intracoronary spasm testing is performed.

Utilizing the Postvascular Phase of Contrast-Enhanced Ultrasound to Predict Breast Cancer Lymph Node Metastasis

Background and Objectives: To evaluate the value of the postvascular phase of contrast-enhanced ultrasound (CEUS) in differentiating between benign and metastatic lymph nodes (LNs) in patients with breast cancer (BC). Materials and Methods: This study retrospectively analyzed 96 suspicious LNs in the lymphatic drainage area of the breast from 90 patients with BC. All LNs were assessed by conventional ultrasound (US) and CEUS following intravenous Sonazoid injection. All LNs underwent puncture biopsy, and pathological results were obtained. The correlations between US and CEUS indicators of LNs and LN metastasis (LNM) were analyzed. Results: Of the 96 LNs, 66 were metastatic. Overall, 80.00% (24/30) of the benign LNs exhibited relative hyper-enhancement in the postvascular phase, whereas 96.97% (64/66) of the metastatic LNs exhibited relative hypo-enhancement (p &lt; 0.001). This CEUS finding was highly predictive of metastasis, with a sensitivity of 96.97%, specificity of 80.00%, positive predictive value of 91.43%, negative predictive value of 92.31%, and accuracy of 91.67%. The mean postvascular phase intensity (MPI) was significantly lower for malignant (median MPI, 12 dB) than for benign (median MPI, 75 dB) LNs. The postvascular phase was more sensitive, specific, and accurate than conventional US or the vascular phase of CEUS for the diagnosis of LNM, with an area under the curve of 0.95 (95% confidence interval: 0.89–0.99). Conclusions: Qualitative and quantitative indicators of the postvascular phase of CEUS provide a reliable diagnostic approach to differentiate benign and metastatic LNs in patients with BC.

The role of PD-L1 in patients with non-small cell lung cancer receiving neoadjuvant immune checkpoint inhibitor plus chemotherapy: a meta-analysis

Background: The use of immune checkpoint inhibitors (ICIs) as neoadjuvant therapy is a promising novel approach in resectable non-small-cell lung cancer (NSCLC). This study aimed to investigate the prognostic value of PD-L1 in patients with NSCLC receiving neoadjuvant immune checkpoint inhibitor plus chemotherapy (CT). Materials and methods: Several databases (PubMed, Embase, and cochrane central register of controlled trials [CENTRAL]) were systematically searched. Randomized controlled trials (RCTs) investigating pathological and survival outcomes with neoadjuvant ICI + CT versus CT alone in NSCLC were analyzed. Results: Overall, eight RCTs (n = 3,404) were included. The analyses showed neoadjuvant ICI + CT significantly improved complete pathological response (pCR) and event-free survival (EFS) in either tumor PD-L1 < 1%, ≥ 1%, 1-49%, or ≥ 50% population (both p < 0.0001) compared with neoadjuvant CT alone. The overall survival (OS) data are not yet mature among all included RCTs, and only three RCTs presented OS data by PD-L1 status of patients. The pooled OS favored neoadjuvant ICI + CT in the PD-L1 ≥ 1% population (hazard ratio [HR], 0.45; 95% CI, 0.31–0.65; p < 0.0001), but not in the PD-L1 < 1% population (HR, 0.89; 95% CI, 0.66–1.19; p = 0.43). Conclusions: Compared with neoadjuvant CT alone, neoadjuvant ICI + CT significantly enhanced pCR and EFS for patients with resectable NSCLC regardless of the expression of PD-L1. It seems that only patients with PD-L1 positive tumors may achieve a better OS, but it’s currently inconclusive due to immature data, so future research with long-term follow-up is still needed.

The value of multiple diffusion metrics based on whole-lesion histogram analysis in evaluating the subtypes and proliferation status of non-small cell lung cancer

ObjectiveLimited studies have explored the utility of whole-lesion histogram analysis in discerning the subtypes and proliferation status of non-small cell lung cancer (NSCLC), despite its potential to provide comprehensive tissue assessment through the computation of additional quantitative metrics. This study sought to assess the significance of intravoxel incoherent motion (IVIM) and diffusion kurtosis imaging (DKI) histogram parameters in discriminating between squamous cell carcinoma (SCC) and adenocarcinoma (AC), and to examine the correlation of each parameter with the proliferative marker Ki-67.Materials and methodsPatients with space-occupying lesions detected by chest CT examination and with further routine MRI, DKI and IVIM functional sequence scans were enrolled. Based on the pathological results, seventy patients with NSCLC were selected and divided into AC and SCC groups. Histogram parameters of IVIM (D, D*, f) and DKI (Dapp, Kapp) were calculated, and the Mann–Whitney U test or independent samples t test was used to analyze the differences in each histogram parameter of the SCC and AC groups. Receiver operating characteristic (ROC) curves were used to evaluate the diagnostic performance of the histogram parameters. The correlation coefficient between histogram parameters and Ki-67 was calculated using Spearman’s or Pearson’s methods.ResultsThe D 10th percentile, D 90th percentile, D mean, D median, Dapp10th percentile, Dapp90th percentile, Dappmean, Dappmedian, Dappskewness, DappSD of the AC groups were significantly higher than those of the SCC groups, while the Kappentropy and KappSD of the SCC groups were significantly higher than those of the AC groups. All the above differences were statistically significant (all P &amp;lt; 0.05). ROC curve analysis revealed that Dappmean showed the best performance for differentiating AC from SCC lesions, with an area under the ROC curve of 0.832 (95% confidence interval [CI]: 0.707-0.919). But there was no statistically significant difference in diagnostic efficacy compared to other histogram parameters (all P&amp;gt;0.05). Dapp90thpercentile, Dappmean, Kappskewnes showed a slight negative correlation with Ki-67 expression (r value -0.340, -0.287, -0.344, respectively; P&amp;lt; 0.05), while the other histogram parameters showed no significant correlation with Ki-67 (all P &amp;gt; 0.05).ConclusionsOur study demonstrates the utility of IVIM and DKI histogram analyses in differentiating NSCLC subtypes, particularly AC and SCC. Correlations with the Ki-67 index suggest that Dappmean, Dapp90th percentile, and Kappskewness may serve as markers of tumor aggressiveness, supporting their use in NSCLC diagnosis and treatment planning.

Laparotomy versus laparoscopy for the treatment of adnexal torsion during pregnancy

BackgroundAdnexal torsion (AT) is a rare emergency complication during pregnancy. Increasing evidence implies that operative laparoscopy for adnexal torsion performed during pregnancy could be safe and feasible. We procured and evaluated the surgical and obstetric outcomes between laparoscopy and laparotomy to determine the optimal approach for treating AT during pregnancy.MethodsThis was a retrospective study involving telephone questionnaire on adnexal torsion during pregnancy that occurred between July 2012 and July 2023 in the First Affiliated Hospital of Zhengzhou University. The study cohort included 155 pregnant women who underwent laparotomy or laparoscopic surgery. The clinical characteristics, surgical interventions, postoperative pathology and pregnancy outcomes were analyzed.ResultsA total of 102 patients were treated by laparoscopy, and 53 patients were treated by laparotomy. Compared with the laparotomy group, the laparoscopy group had significantly less blood loss (17.5 ml vs. 20.0 ml, p = .004), a lower incidence of delayed incision healing (1.0% vs. 11.3%, p = .011), and a shorter hospital stay (5.0 days vs. 8.0 days, p < .001). There was no significant difference between the two groups in terms of obstetric outcomes, including preterm delivery, miscarriage rate, birth weight, delivery gestation, cesarean delivery rate, or neonatal intensive care unit admission. All the pathological findings were benign except for one case of borderline mucinous cystadenoma. The most common pathological types were luteal cysts in the laparoscopy group and mature teratomas in the laparotomy group.ConclusionIn this retrospective study, compared with laparotomy, laparoscopy yielded successful outcomes, with less surgical bleeding, less delayed wound healing, and shorter hospital stays. Laparoscopy could be a promising approach for diagnosing and treating AT during pregnancy.

Fisher discriminant analysis of multimodal ultrasound in diagnosis of cervical metastatic lymph nodes in papillary thyroid cancer.

The purpose of this study was to develop a diagnostic model utilizing multimodal ultrasound parameters to aid in the detection of cervical lymph node metastasis in papillary thyroid cancer (PTC) patients. The study included 84 suspicious lymph nodes from 69 PTC patients, all of whom underwent fine needle aspiration with pathological results. Data from conventional grayscale ultrasound, shear wave elastography (SWE), and superb microvascular imaging were analyzed. Key ultrasound features were compared between benign and metastatic groups to create a diagnostic model using Fisher's stepwise discriminant analysis. The model's effectiveness was assessed with self-testing, cross-validation, and receiver operating characteristic curve analysis. Four features, namely lymphatic hilum (X1), cortical hyperechogenicity (X2), vascular pattern (X4), and SWEmean (X7), were integral to the discriminant analysis, resulting in the equation: Y1 = -3.461 + 2.423X1 + 0.321X2 + 1.620X4 + 0.109X7, Y2 = -8.053 + 0.414X1 + 2.600X2 + 2.504X4 + 0.192X7. If Y1 < Y2, the LN would be diagnosed as metastatic lymph nodes. The model demonstrated an area under the curve of 0.833, with a sensitivity of 83.33% and specificity of 83.33%. The multimodal ultrasound diagnostic model, established through Fisher's stepwise discriminant analysis, proved effective in identifying metastatic lymph nodes in PTC patients.

Primary hepatoid adenocarcinoma of the lung in patient with silicosis: a case report and literature review

IntroductionHepatoid adenocarcinoma of the lung (HAL) is a special type of adenocarcinoma originating from the lung with adenoid- and hepatocyte-like differentiation. HAL is rare in clinical practice. Here, we present the case of a patient with HAL.Case presentationA 59-year-old man was admitted to the hospital 4 days because of lung mas observed. Chest computed tomography (CT) revealed a lobulated mass shadow in the right lower lobe, approximately 3.5 × 3.3 cm in size. CT-guided percutaneous biopsy of the right lower lung was performed. The pathological results indicated a moderately to poorly differentiated adenocarcinoma. The patient underwent thoracoscopic right middle and lower lobectomy and systematic lymph node dissection. The postoperative pathology was primary HAL, with the staging of T2bN2M0 (stage III A). Recurrence-free survival and overall survival were 6 and 19 months, respectively Preoperatively, the level of alpha-fetoprotein was negative; however, after recurrence, it increased to 87.8.ConclusionPulmonary hepatoid adenocarcinoma is a rare subtype of malignant lung tumor, combined silicosis is more rare. Early surgical intervention can benefit patients in the early stages of the disease, whereas chemotherapy remains the main systemic treatment modality for postoperative and advanced stages. With the increasing popularity of genetic testing, it is important to focus on improving genetic examination.

Diagnostic Value of Contrast-Enhanced Ultrasound in Differentiating Malignant from Benign Small Renal Masses After CT/MRI

Background: The aim of this study was to assess the diagnostic performance of contrast-enhanced ultrasound (CEUS) in characterizing small renal masses (SRMs) measuring less than 3 cm and in distinguishing between malignant and benign SRMs. Methods: A retrospective study was conducted between January 2022 and January 2023 at the Radiology Department of (Anonymized data), with a total of 43 patients assessed via CT and MRI scans, which were subsequently studied by experienced radiologists who were blinded to the pathology results. The CEUS findings were then compared with histopathological examination outcomes or follow-up imaging results. Results: The study results revealed a notably high level of diagnostic accuracy, with sensitivity at 0.875, specificity at 0.94, positive predictive value at 0.95, and negative predictive value at 0.86 for characterizing SRMs. Spearman rank correlation analysis substantiated a robust positive linear correlation between the CEUS findings and biopsy results (r = 0.972). Conclusions: These findings underscore the potential utility of CEUS as a valuable tool for discriminating between malignant and benign SRMs, carrying significant implications for clinical decision-making and leading to improved patient outcomes. However, larger validation studies are imperative to establish its role in routine clinical practice and to address potential limitations.

Diabetes, hypertension, and hospitalizations during pregnancy: a multivariate analysis

Abstract Introduction The study analyzes the correlation between socio-demographic variables and pathologies encountered by women during pregnancy. The presence of these pathologies is recorded at the time of compiling the CAP (Certificate of Assistance for Birth). Methods Data analysis pertains to the Certificate of Assistance for Birth (CAP) concerning residents in the territory of AUSL South-East Tuscany in the years 2021 and 2022. The number of women of childbearing age in Tuscany in 2022 is 150,959, while the number of births analyzed in the study is 9,053. The study conducts multivariate analysis between socio-demographic variables and pathological outcomes. Results Controlling for age, citizenship and other factors, the risk of gestational diabetes is significantly higher (p &amp;lt; 0.05) among mothers: over 40 years old (OR = 1.56), with citizenship in PFPM countries (OR = 1.60) and particularly, compared to Italians, among women from Indian subcontinent (OR = 3.73) and the Maghreb (OR = 2.04), with lower educational levels (OR = 1.28) compared to graduates, obese (OR = 2.43). The risk of gestational hypertension is significantly higher (p &amp;lt; 0.05) among mothers: over 40 years old (OR = 1.71), obese (OR = 2.50), nulliparous (OR = 1.60). The risk of one or more hospitalizations during pregnancy is significantly higher (p &amp;lt; 0.05) among mothers: not employed (OR = 1.31) and homemakers (OR = 1.32) compared to employed, from Indian subcontinent (OR = 1.82) and the Maghreb (OR = 1.75) compared to Italians, with gestational hypertension (OR = 2.06). Conclusions Unlike gestational diabetes and hospitalizations during pregnancy, gestational hypertension does not show significant associations with the mother’s socio-demographic characteristics. However, gestational diabetes and hospitalizations during pregnancy are correlated with different variables: they are more common among women over 40, foreigners, homemakers, with lower educational levels, obese, and with low family economic status. Key messages • It has been observed that some variables are also risk factors for adult age pathologies, such as diabetes and hypertension. • The importance of Early Childhood Development and early interventions can improve children’s health and well-being.

Spinal Upper Thoracic Extradural Meningioma: A Case Report and Literature Review

The most common extradural spinal lesions are metastatic tumors. However, approximately 2.5% to 3.5% of spinal meningiomas are extradural meningiomas. This article describes a rare case of a thoracic extradural meningioma. A 58-year-old woman was admitted following two months of gait disturbance. Magnetic resonance imaging suggested an extradural meningioma at the T1-5 level. Radical surgical resection was performed, and the lesion was pathologically identified as meningothelial meningioma. Additionally, we reviewed and summarized 12 cases of spinal extradural masses since 2018. Based on the literature, we discuss the location, pathology, and clinical outcomes of these uncommon lesions.

Risk factors of cervical central lymph node metastasis in stage T1a unifocal papillary thyroid carcinoma

To investigate the correlation of cervical central lymph node metastasis (CLNM) in stage T1a unifocal papillary thyroid carcinoma (PTC) with the clinicopathological characteristics, ultrasonography features and the number of lymph node dissection, and to analyze the risk factors of CLNM. Data from 493 unifocal PTC patients (T1a) who underwent partial or total thyroidectomy and pCLND at the Guizhou Provincial People’s Hospital were collected and retrospectively analyzed. They were divided into two groups in accordance with cervical CLNM or not. Their information, including clinical characteristics, ultrasound (US) features, pathological results, and other characteristics of the groups, was analyzed and compared using univariate and multivariate logistic regression analyses. A total of 493 patients were eligible in this study. Among them, 33.7% (166/493) of PTC patients had cervical CLNM, and 66.3% (327/493) did not. The two groups were compared using a univariate analyses, and there were no significant differences between the two groups in age, maximum tumor size, tumor location, aspect ratio, boundary, morphology, echogenicity, BRAFV600E and HT (P > 0.05), and there were significant differences between gender, capsule contact, microcalcifications, rich vascularity, and number of lymph node dissection (P < 0.05). A multivariate logistic regression analyses was performed to further clarify the correlation of these indices. However, only male (OR = 1.770, P = 0.009), microcalcifications (OR = 1.791, P = 0.004), capsule contact (OR = 1.857, P = 0.01), and number of lymph node dissection (OR = 2.274, P < 0.001) were independent predictors of cervical CLNM. In conclusion, four independent predictors of cervical CLNM, including male, microcalcifications, capsule contact, and number of lymph node dissection, were screened out. Therefore, a comprehensive assessment of these risk factors should be conducted when designing individualized treatment regimens for PTC patients.
