A Case of CUP with Malignant Pleural Effusion: Overcoming Diagnostic and Therapeutic Hurdles with Chemotherapy

Introduction: Cancers of unknown primary (CUPs) present a diagnostic challenge as their origin is unidentified at diagnosis. Massive pleural effusion (MPE), indicative of lung metastasis in CUP, categorizes the condition into an unfavorable subset with a poor prognosis. Patients in this subset may exhibit a lower response to specific therapies. Case Presentation: A 62-year-old woman presented with cough, severe dyspnea, and MPE in the left lung. Thoracocentesis was performed, extracting 1,200 mL of hemorrhagic fluid, followed by the placement of an indwelling pleural catheter. The cytological examination of the pleural effusion indicated an adenocarcinoma, with immunohistochemistry revealing positive CK7 and negative CK20, Napsin A, and TTF-1. Additionally, elevated levels of Ca-125 (1,605 U/mL) and Ca 15-3 (242 U/mL) raised suspicion of gynecological malignancy. Thorax and abdominal CT scans, breast and thyroid ultrasounds showed no signs of malignancy, leading to the diagnosis of CUP. The patient’s performance status according to the Eastern Cooperative Oncology Group (ECOG) score was 4. Initial carboplatin 5 AUC and paclitaxel 175 mg/m2 administration resulted in improvement in performance status with ECOG score of 1, alleviation of dyspnea, reduction in pleural effusion 1 week after chemotherapy, with minimal effusion observed at 3 weeks, and Ca-125 levels decreased to 33.6 U/mL thereafter. Discussion: Empiric chemotherapy using carboplatin and paclitaxel is a feasible option for managing CUP with MPE mimicking gynecological malignancies with elevated Ca-125 and Ca 15-3 markers; initiating chemotherapy in poor performance status patients is beneficial with proper clinical judgment.

Prognostic factors for intraductal papillary neoplasm of the bile duct following surgical resection: a systematic review and meta-analysis.

Intraductal papillary neoplasm of the bile duct (IPNB) is a biliary neoplasm characterized by intraductal papillary growth and varying degrees of malignant transformation. This study aimed to identify effective prognostic factors (PFs) for predicting the prognosis of IPNB after surgical resection, addressing the gap in the higher level evidence. We systematically searched databases from their inception to October 10, 2023. Data on 12 predetermined PFs were collected and subjected to a meta-analysis. Forest plots were used to summarize the findings. Fifteen studies with a total of 2311 patients were included. Among the PFs examined, extrahepatic tumor location (HR, 2.97; 95% CI 1.68-5.23), subclassification type 2 (HR, 2.62; 95% CI 1.45-4.76), R1 resection (HR, 2.47; 95% CI 1.73-3.51), elevated CA19-9 level (HR, 3.25; 95% CI 1.91-5.54), tumor multiplicity (HR, 2.65; 95% CI 1.40-5.02), and adjacent organ invasion (HR, 3.17; 95% CI 2.01-5.00) were associated with a poorer prognosis. Additionally, the combined HR values indicated that lymph node metastasis and poor tumor differentiation were linked to a worse prognosis, although both exhibited significant heterogeneity. Our study offers valuable insights for enhancing postoperative prognostication and treatment decision-making for IPNB patients with IPNB. These findings warrant further validation in future prospective studies.

Clinicopathological Characteristics of Small Cell Carcinoma of the Ovary, Hypercalcemic Type – a case Series

Abstract Introduction/Objective Small cell carcinoma of the ovary hypercalcemic type (SCCOHT) is a rare (<0.01%) and aggressive ovarian tumor primarily affecting young women (median of approximately 24 years), characterized by rapid growth, early metastasis, and association with hypercalcemia in two-thirds of cases. The diagnosis of SCCOHT is challenging due to its rarity and lack of specific clinical symptoms or biomarkers. Our study aims to delineate the clinicopathologic characteristics of SCCOHT based on our case series and add to the existing knowledge. Methods/Case Report A retrospective review of University of Pennsylvania Health system pathology database was conducted from 2012 to 2024. Our study identified four patients diagnosed with SCCOHT. Clinical information and histopathologic characteristics were reviewed. Results (if a Case Study enter NA) Among the four patients identified, the median age was 24 years, with a median tumor size of 14.5 cm, and all patients presented with weight loss, abdomen bloating, and elevated CA125 levels. Notably, two patients exhibited hypercalcemia, while one initially presented with normal calcium levels but developed hypercalcemia during disease recurrence. One patient maintained normal calcium levels throughout. Surgical intervention involved bilateral salpingo-oophorectomy in all cases, with pathological staging revealing two patients at pT1a, one at pT1c, and one at pT3c. Histopathological analysis consistently revealed similar morphology, including solid and cystic necrotic neoplasms with diffuse growth or nests/cords of undifferentiated small cells, which displaying vesicular chromatin and prominent nucleoli. Immunohistochemical staining demonstrated loss of BRG1 (SMARCA4) expression in two patients and diffuse positivity for WT1 in all patietns, while negative for cytokeratin, germ cell markers, and melanocytic markers. Genetic test revealed SMARCA4 mutation (p.E 717*, c.3169-1G>A) in one patient. Conclusion Small cell carcinoma of the ovary, hypercalcemic type, presents a diagnostic and therapeutic challenge due to its rarity and aggressive nature. Adequate treatment options are currently limited, highlighting the critical need for further research and development of targeted therapies in SCCOHT. Testing for mutations in the SMARCA4 gene is essential for accurate diagnosis of SCCOHT and may uncover new avenues for treatment and management strategies.

Sex-specific association between carbohydrate antigen 19–9 and incident type 2 diabetes

Carbohydrate antigen 19–9 (CA19-9) levels are associated with glycemic control, insulin resistance, and chronic complications in patients with type 2 diabetes (T2D). Women generally show higher CA19-9 levels despite a greater T2D prevalence in men. We evaluated the sex-specific longitudinal associations between CA19-9 levels and T2D incidence. Korean adults (n = 329,380) without previous cancer or T2D were categorized into four groups based on their CA19-9 levels. The study end point was the development of incident T2D during follow-up. Cox proportional hazards models were used to estimate hazard ratios (HR) according to CA19-9 levels. During a median follow-up of 6.1 years (3.3–9.3 years), the incidence rates of T2D were 9.9 per 1,000 person-years in men and 3.6 per 1,000 person-years in women. In the time-dependent analysis, adjusted HRs (95% confidence intervals) for incident T2D comparing CA19-9 levels of 10.0–19.9, 20.0–29.9, and ≥ 30 U/mL to the reference (< 10 U/mL) were 1.08 (1.04–1.13), 1.18 (1.07–1.30), and 1.64 (1.35–1.99), respectively, among men. However, this association was not observed in women. The association between CA19-9 category and incident T2D significantly differed by sex (Pinteraction = 0.006). Among young and middle-aged Korean adults, elevated CA19-9 levels were significantly associated with increased risk of type 2 diabetes in men but not in women. Elevated CA19-9 levels in men could be a useful marker for identifying individuals at high risk of developing T2D. Evaluation approaches for individuals with elevated CA19-9 levels should be sex-specific.

Mining Candidate Genes and Identifying Risk Factors for Leg Disease in Broilers: A Mendelian Randomization Study.

Clinical investigations have highlighted disruptions in bone metabolic processes and abnormal fluctuations in serum indicator levels during the onset of leg disease (LD) in broilers. However, the presence of a genetic causal relationship for this association remains undetermined. Therefore, the aim of this study is to discern the risk factors underlying LD development using 1235 sequenced white-feathered broilers. We employed Mendelian randomization (MR) analysis to assess the associations of bone strength (BS), bone mineral density (BMD), tibial bone weight (TBW), tibial bone length (TBL), tibial bone diameter (TBD), bone ash (BA), ash calcium (Ash Ca), ash phosphorus (Ash P), serum calcium (Ca), serum phosphorus (P), serum alkaline phosphatase (ALP), and serum osteoprotegerin (OPG) with the incidence of LD. Compelling evidence underscores a causal link between the risk of developing LD and decreased BMD (odds ratio (OR) = 0.998; 95% CI: 0.983, 0.993; P < 0.001) and narrower TBD (OR = 0.985, 95% CI: 0.975, 0.994, P = 0.002). Additionally, serum OPG concentrations (OR: 0.995, 95% CI: 0.992, 0.999, P = 0.008) were associated with BMD (OR = 0.0078, 95% CI = 0.0043 to 0.0140, P < 0.001), indicating a robust genetic relationship between ALP concentrations (OR: 0.988, 95% CI: 0.984, 0.993, P < 0.001) and TBD (OR = 0.0046, 95% CI = 0.0026, 0.0083, P < 0.001). Moreover, elevated serum Ca (OR: 0.564, 95% CI: 0.487, 0.655, P < 0.001) and P (OR: 0.614, 95% CI: 0.539, 0.699, P < 0.001) levels were associated with a narrower TBD. Elevated serum levels of Ca, P, ALP, and OPG contribute to disturbances in bone metabolism, while decreased BMD and narrower TBD are associated with a greater risk of developing LD in broilers. This discovery elucidates the metabolic risk factors for LD in broilers and could provide information on LDs, such as osteoporosis, in humans.

In Pursuit of Novel Markers: Unraveling the Potential of miR-106, CEA and CA 19-9 in Gastric Adenocarcinoma Diagnosis and Staging.

Gastric cancer stands as the fourth leading cause of cancer-related deaths globally, primarily comprising adenocarcinomas, categorized by anatomic location and histologic type. Often diagnosed at advanced stages, gastric cancer prognosis remains poor. To address the critical need for accurate tumoral markers for gastric cancer diagnosis, we conducted a study to assess classical markers like CEA and CA-19-9 alongside the novel marker miR-106. Our investigation revealed distinct dynamics of these markers compared to non-cancerous groups, although no disparities were observed across different disease stages. Univariable and multivariable logistic regression analyses demonstrated that elevated levels of miR-106, CEA and CA 19-9 were predictive of a positive histopathological exam, with the respective odds ratios of 12.032 (95% CI: 1.948-74.305), 30 (95% CI: 3.141-286.576), and 55.866 (95% CI: 4.512-691.687). Subsequently, we utilized predicted probabilities from regression models to construct receiver operating characteristic (ROC) curves, identifying CA 19-9 as the optimal predictor for gastric adenocarcinoma diagnosis when considering age and gender, with an area under the curve (AUC) of 0.936 (p < 0.001). Hence, classical markers exhibit superior performance compared to the novel marker miR-106 in predicting gastric adenocarcinoma.

Comparison of Recurrence and Survival Between Patients With Pathological Stage I Epithelial Ovarian Cancer After Laparoscopic or Laparotomic Surgery: Retrospective Analysis of a Propensity-Matched Cohort

ObjectiveTo compare oncologic outcomes after laparoscopic or laparotomic surgery to treat epithelial ovarian carcinoma in FIGO Stage I. DesignRetrospective cohort study. SettingGynecological cancer ward in a tertiary hospital. ParticipantsA total of 85 patients with FIGO Stage I epithelial ovarian carcinoma who underwent laparoscopic staging surgery and 206 who underwent laparotomic staging surgery at West China Second Hospital, Sichuan University (Chengdu, China) between January 1, 2013 and December 31, 2019. InterventionsLaparoscopic surgery or laparotomic staging surgery. ResultsBefore propensity score-based matching, the laparotomy group showed higher prevalence of preoperative elevated CA125 level (48.5% vs 35.3%, p = .045) and tumors >15 cm (27.2% vs 5.9%, p <.001). Multivariate analysis associated higher body mass index with better overall survival (adjusted HR 0.83, 95% CI 0.70–0.99, p = .043). Among propensity score-matched patients (82 per group) who were matched to each other according to propensity scoring based on age, body mass index, CA125 level, largest tumor diameter, FIGO stage, history of abdominal surgery, and American Society of Anesthesiologists grade, the rate of progression-free survival at 5 years was similar between the laparoscopy group (87.1%, 95% CI 79.3–95.7%) and the laparotomy group (90.9%, 95% CI 84.7–97.6%, p = .524), as was the rate of overall survival at 5 years (93.9%, 95% CI 88.0–100.0% vs 94.7%, 95% CI 89.8–99.9%, p = .900). Regardless of whether patients were matched, the two groups showed similar rates of recurrence of 9–11% during follow-up lasting a median of 54.9 months. ConclusionsRates of recurrence and survival may be similar between laparoscopy or laparotomy to treat Stage I epithelial ovarian cancer. Since laparoscopy is associated with less bleeding and faster recovery, it may be a safe, effective alternative to laparotomy for appropriate patients.

Tubo-Ovarian Abscess with Highly Elevated CA125 Level is Misdiagnosed as Ovarian Cancer: A Case Report

Tubo-Ovarian Abscess with Highly Elevated CA125 Level is Misdiagnosed as Ovarian Cancer: A Case Report

Uterine tumors resembling ovarian sex cord tumors: A retrospective analysis of 7 cases from a single institution.

To investigate the clinicopathological features, diagnosis, surgical treatment and prognosis of uterine tumors similar to ovarian sex cord tumors (UTROSCT). The clinical data, surgical approach, histopathological, and immunohistochemical features of 7 cases of UTROSCTs were retrospectively reviewed and followed up. All 4 patients were premenopausal women. The most common clinical presentation was menorrhagia (n = 4) followed by postmenopausal lower abdominal mass (n = 2) and postmenopausal bleeding (n = 1). Gynecological ultrasonography suggested uterine fibroids in 4 cases, adenomyosis with uterine fibroids in 2 cases, and an intrauterine mass in 1 case. Pelvic MRI was performed preoperatively in only 2 cases, and both indicated uterine fibroid degeneration, including 1 patient with suspected malignancy. Preoperative serum tumor markers were measured in 6 patients, and only 1 patient had elevated CA125 levels, up to 158 U/mL. Total hysterectomy with bilateral adnexectomy or salpingectomy was the most common treatment pattern (n = 6). The tumors were located within the myometrium (n = 4), submucosa (n = 1), and isthmus to external cervical os (n = 1), with a range of 2 to 12 (mean = 8) cm. Edema and degeneration were observed in 2 cases, and necrosis in 1 case. Postoperative follow-up ranged from 31 to 82 (mean = 43) months. Unfortunately, 1 patient died at 54 months of follow-up without undergoing hysterectomy. The remaining 6 cases showed no tumor recurrence or metastasis after surgery. Histological examination revealed a tumor composed of epithelioid tumor-like cells arranged in cords, trabeculae, and nests. All 7 tumors showed expression of 2 sex cord differentiation markers. Furthermore, all tumors expressed the smooth muscle marker, while epithelial marker CK (4/7). endometrial stromal marker CD10(0/7). The Ki-67 proliferation index was found to be <5% (5/7). The option of total hysterectomy may be considered for women who do not have any fertility requirements. However, for young women who desire to maintain their reproductive capacity, surgery to preserve the uterus may be an alternative, although it necessitates careful postoperative monitoring. In terms of follow-up monitoring, MRI is more suitable than ultrasound. The diagnosis of UTROSCT heavily relies on histopathological examination and immunohistochemical analysis.

Identification of gemcitabine resistance-related AHNAK2 gene associated with prognosis and immune infiltration in pancreatic cancer

PurposeGemcitabine is a basic chemotherapy drug for pancreatic cancer (PC), but resistance is common and causes tumor recurrence and metastasis. Therefore, it is significant to explore gemcitabine resistance-related molecules for individualized treatment and prognosis assessment of PC. MethodsIn this study, transcriptome sequencing and TCGA database analysis were performed, and a differentiated gene AHNAK2 was screened. MEXPRESS database, tissue microarray analysis, and CIBERSORT and TIMER databases were used to correlate AHNAK2 expression with clinicopathological features and prognosis and immune infiltration of PC. Enrichment analysis was used to investigate the significant biological processes associated with AHNAK2. ResultsAHNAK2 was highly expressed in gemcitabine-resistant cells. High expression of AHNAK2 increased the risk of poor overall survival (OS) and progression-free survival (PFS) in PC. Clinicopathologic analysis revealed that AHNAK2 correlated with KRAS, TP53 mutations, histologic type, short OS, N stage, and elevated CA199 levels in PC. Knockdown of AHNAK2 inhibited the ability of cell proliferation and colony formation and enhanced the toxic effect of gemcitabine in PC. Meanwhile, the knockdown of AHNAK2 expression enhanced cell-ECM adhesion, inhibited cell-cell adhesion, and downregulated the KRAS/p53 signaling pathway in PC. Furthermore, AHNAK2 was correlated with immune infiltration, especially B cells and macrophages. ConclusionsOur study unveils for the first time the pivotal role of AHNAK2 in PC, particularly its association with gemcitabine resistance, clinical prognosis, and immune infiltration. AHNAK2 not only drives the proliferation and drug resistance of PC cells by potentially activating the KRAS/p53 pathway but also significantly impacts cell-cell and cell- ECM adhesion. Additionally, AHNAK2 plays a crucial role in modulating the tumor immune microenvironment. These insights underscore AHNAK2's unique potential as a novel therapeutic target for overcoming gemcitabine resistance, offering new perspectives for PC treatment strategies.

High-grade serous carcinoma of the fallopian tube in a young woman with chromosomal 4q abnormality: A case report

BACKGROUND Few studies have reported an association between an increased risk of acquiring cancers and survival in patients with 4q deletion syndrome. This study presents a rare association between chromosome 4q abnormalities and fallopian tube high-grade serous carcinoma (HGSC) in a young woman. CASE SUMMARY A 35-year-old woman presented with acute dull abdominal pain and a known chromosomal abnormality involving 4q13.3 duplication and 4q23q24 deletion. Upon arrival at the emergency room, her abdomen appeared ovoid and distended with palpable shifting dullness. Ascites were identified through abdominal ultrasound, and computed tomography revealed an omentum cake and an enlarged bilateral adnexa. Blood tests showed elevated CA-125 levels. Paracentesis was conducted, and immunohistochemistry indicated that the cancer cells favored an ovarian origin, making us suspect ovarian cancer. The patient underwent debulking surgery, which led to a diagnosis of stage IIIC HGSC of the fallopian tube. Subsequently, the patient received adjuvant chemotherapy with carboplatin and paclitaxel, resulting in stable current condition. CONCLUSION This study demonstrates a rare correlation between a chromosome 4q abnormality and HGSC. UBE2D3 may affect crucial cancer-related pathways, including P53, BRCA, cyclin D, and tyrosine kinase receptors, thereby possibly contributing to cancer development. In addition, ADH1 and DDIT4 may be potential influencers of both carcinogenic and therapeutic responses.

Impact of surgical compliance on survival prognosis of patients with ovarian cancer and associated influencing factors: A propensity score matching analysis of the SEER database

PurposeTo evaluate the impact of surgical compliance on overall survival (OS) and cancer-specific survival (CSS) in ovarian cancer patients and identify factors influencing surgical compliance. Materials and methodsData from patients with ovarian cancer in the SEER database (2004–2015) were analyzed to compare the characteristics of patients with high and low surgical compliance. Kaplan-Meier curves and Cox regression models were used to assess the impact of surgical compliance on survival outcomes. Nomograms incorporating surgical compliance and independent prognostic factors were constructed to predict OS and CSS and were validated using internal validation sets. Predictive accuracy was evaluated using Harrell's concordance index (C-index), decision curve analysis (DCA), receiver operating characteristic (ROC) curves, and calibration plots. Binary logistic regression analysis identified factors significantly affecting surgical compliance, and propensity score matching (PSM) was used to adjust for confounders. ResultsAmong the 41,859 patients, 783 (1.87 %) demonstrated poor surgical compliance, while 41,076 (98.13 %) exhibited good compliance. Surgical compliance has emerged as an independent prognostic indicator for ovarian cancer. Patients with high compliance had significantly better OS and CSS rates (P < 0.0001). The prognostic models were internally validated and showed strong discriminative and calibration capabilities. Factors affecting compliance included older age, advanced pathological stage, metastasis, elevated CA-125 levels, and lower income. After PSM, Kaplan-Meier analysis revealed significantly improved survival in patients with good compliance (P < 0.0001). ConclusionSurgical compliance is a pivotal and independent predictor of overall and cancer-specific survival in patients undergoing OC. Factors contributing to lower surgical compliance include advanced age, later tumor stage, metastatic spread, elevated CA-125 levels, and reduced family income.

Surgical treatment for pulmonary metastasis from ovarian cancer: a retrospective case series

BackgroundDistant metastases of ovarian cancer are rarely detected alone. The effectiveness of surgical intervention for pulmonary metastases from ovarian cancer remains uncertain. This study aimed to investigate the clinicopathologic characteristics and outcomes of patients undergoing resection for pulmonary metastasis from ovarian cancer.Case presentationThe clinicopathologic characteristics and outcomes of radical surgery for pulmonary metastasis from ovarian cancer were investigated. Out of 537 patients who underwent pulmonary metastasis resection at two affiliated hospitals between 2010 and 2021, four (0.74%) patients who underwent radical surgery for pulmonary metastasis from ovarian cancer were included. The patients were aged 67, 47, 21, and 59 years; the intervals from primary surgery to detection of pulmonary metastasis from ovarian cancer were 94, 21, 36, and 50 months; and the overall survival times after pulmonary metastasectomy were 53, 50, 94, and 34 months, respectively. Three of the four patients experienced recurrence after pulmonary metastasectomy. Further, preoperative carbohydrate antigen (CA) 125 levels were normal in two surviving patients and elevated in the two deceased patients.ConclusionIn this study, three of the four patients experienced recurrence after pulmonary metastasectomy, but all patients survived for > 30 months after surgery. Patients with ovarian cancer and elevated CA125 levels may not be optimal candidates for pulmonary metastasectomy. To establish appropriate criteria for pulmonary metastasectomy in patients with ovarian cancer, further research on a larger patient cohort is warranted.

SynopsisA case report on a patient with a mucinous borderline ovarian cystadenoma with extremely elevated CA199 levels.

Construction of a nomogram based on clinicopathologic features to predict the likelihood of No. 253 lymph node metastasis in rectal cancer patients.

To explore the high-risk factors for rectal cancer No.253 lymph node metastasis (LNM) and to construct a risk nomogram for the individualized prediction of No.253 LNM. This was a retrospective analysis of 425 patients with rectal cancer who underwent laparoscopic-assisted radical surgery. Independent risk factors for rectal cancer No.253 LNM was identified using multivariate logistic regression analysis, and a risk prediction nomogram was constructed based on the independent risk factors. In addition, the performance of the model was evaluated by discrimination, calibration, and clinical benefit. Multivariate logistic regression analysis showed that No.253 lymphadenectasis on CT (OR 10.697, P < 0.001), preoperative T4-stage (OR 4.431, P = 0.001), undifferentiation (OR 3.753, P = 0.004), and preoperative Ca199 level > 27 U/ml (OR 2.628, P = 0.037) were independent risk factors for No.253 LNM. A nomogram was constructed based on the above four factors. The calibration curve of the nomogram was closer to the ideal diagonal, indicating that the nomogram had a better fitting ability. The area under the ROC curve (AUC) was 0.865, which indicated that the nomogram had high discriminative ability. In addition, decision curve analysis (DCA) showed that the model could show better clinical benefit when the threshold probability was between 1% and 50%. Preoperative No.253 lymphadenectasis on CT, preoperative T4-stage, undifferentiation, and elevated preoperative Ca199 level were found to be independent risk factors for the No.253 LNM. A predictive model based on these risk factors can help surgeons make rational clinical decisions.

Congestion as a crucial factor determining albuminuria in patients with cardiorenal disease.

Albuminuria could potentially emerge as a novel marker of congestion in acute heart failure. However, the current evidence linking albuminuria and congestion in patients with congestive heart failure (CHF) remains somewhat scarce. This study aimed to evaluate the prevalence of albuminuria in a cohort of patients with CHF, identify the independent factors associated with albuminuria and analyse the correlation with different congestion parameters. This is a subanalysis of the Spanish Cardiorenal Registry, in which we enrolled 864 outpatients with heart failure and a value of urinary albumin:creatinine ratio (UACR) at the first visit. The median age was 74years, 549 (63.5%) were male and 438 (50.7%) had a reduced left ventricular ejection fraction. A total of 350 patients (40.5%) had albuminuria. Among these patients, 386 (33.1%) had a UACR of 30-300mg/g and 64 (7.4%) had a UACR >300mg/g. In order of importance, the independent variables associated with higher UACR were estimated glomerular filtration rate determined by the Chronic Kidney Disease Epidemiology Collaboration equation (R2=57.6%), systolic blood pressure (R2=21.1%), previous furosemide equivalent dose (FED; R2=7.5%), antigen carbohydrate 125 (CA125; R2=6.1%), diabetes mellitus (R2=5.6%) and oedema (R2=1.9%). The combined influence of oedema, elevated CA125 levels and the FED accounted for 15.5% of the model's variability. In patients with chronic stable heart failure, the prevalence of albuminuria is high. The risk factors of albuminuria in this population are chronic kidney disease and hypertension. Congestion parameters are also associated with increased albuminuria.

Effect of glycotoxicity and lipotoxicity on carbohydrate antigen 19 − 9 in the patients with diabetes

ObjectivesIn comparison to the subjects without diabetes, a greater concentration of serum carbohydrate antigen 19 − 9 (CA 19 − 9) was observed in the subjects with diabetes. Nevertheless, since the occurrence of abnormal CA 19 − 9 is not widespread among the whole diabetic population, this phenomenon has not attracted enough attention. The prevalence of abnormal CA 19 − 9 in hospitalized patients with diabetes was the focus of our research.MethodA total of 385 subjects with diabetes and 200 controls were enrolled and all had been tested the CA19-9 levels. Cases of cancers were excluded through examination and followup for 1 year.ResultsWe found that the rate of patients with abnormal CA19-9 level was 8.3%. The rate of patients with abnormal CA19-9 level was 14.0% in the HbA1c ≥ 9% group, and 3.0% in the HbA1c < 9% group, 2.5% in the control group. There was no significant difference in the HbA1c < 9% group and the control group. A significant correlation between serum CA19-9 and both HbA1c and total cholesterol was observed, yet no difference in CRP level was observed between subjects with normal CA19-9 level and subjects with abnormal CA19-9 level. However, a significant difference in fasting C-peptide levels was observed between the two groups, p = 0.039.ConclusionThe percentage of patients with diabetes exhibiting elevated CA19-9 level is 14% in the HbA1c ≥ 9% diabetic patients, much higher than expected. The underlying mechanism may be related to islet injury caused by glycotoxicity and lipotoxicity. Strengths and limitations of the studyWe studied the rate of hospitalized diabetic patients with elevated CA 19 − 9 which were characterized with poorly controlled blood glucose. We found that the elevation of CA 19 − 9 was unexpectedly high in diabetic inpatients without development to cancer. The limitation of this study is that the underlying mechanism is not sufficiently studied.

Blood Concentration of Macro- and Microelements in Women Who Are Overweight/Obesity and Their Associations with Serum Biochemistry.

Risk elements in blood matrices can affect human health status through associations with biomarkers at multiple levels. The aim of this study was to analyze 15 macro- and microelements in the blood serum of women with overweight (BMI of ≥25 kg/m2) and obesity (BMI of ≥30 kg/m2) and to examine possible associations with biochemical, liver enzymatic parameters, and markers of oxidative stress. Based on the power calculation, the study involved women (in the postmenopausal stage) with overweight (n = 26) and obesity (n = 22), aged between 50-65 years. Multifrequency bioelectrical impedance analysis was used to measure body composition parameters. Concentrations of elements were determined by inductively coupled plasma optical emission spectrometry, and Hg was measured using cold-vapor atomic absorption spectroscopy. Individuals with obesity, as indicated by a higher BMI, percentage of body fat, and visceral fat area, had elevated serum levels of Ca, Mg, Fe, Al, Sr, Pb, and Hg. Concentrations of Al, Cu, K, Sb, Zn, and Pb significantly affected biochemical and liver function markers in women with overweight or obesity. Elements such as Cu and Al were associated with increased total cholesterol. The correlation analysis between total antioxidant status and Cu, Al, and Ni confirmed associations in both groups. Our findings underscore the importance of addressing excess body weight and obesity in relation to risk elements. The results of the research could be beneficial in identifying potential targets for the treatment or prevention of comorbidities in people with obesity.

Preoperative endoscopic biliary drainage procedures may affect intrahepatic recurrence of cholangiocarcinoma after surgical resection.

468 Background: To determine the impact of preoperative endoscopic nasal biliary drainage (ENBD) and/or endoscopic retrograde biliary drainage (ERBD) procedures on intrahepatic recurrence rate in patients with cholangiocarcinoma after surgical resection. Methods: Between January 2005 and January 2023, 143 patients diagnosed cholangiocarcinoma and received surgical resection. Among 143 patients, 99 patients were treated with preoperative ENBD and/or ERBD. We retrospectively analysed prognostic factors (age, gender, preoperative ENBD and/or ERBD, tumor differentiation, pT factor, lymph node metastasis, surgical margin, lymphovascular invasion, preoperative maximal total bilirubin, postoperative chemoradiation/chemotherapy/radiation therapy, CA19-9) for recurrence after surgical resection. Results: Intrahepatic recurrence after surgical resection was detected in 22 /99(22.2%) patients with preoperative ENBD and/or ERBD, and 5/44(11.4%) patients without preoperative ENBD and/or ERBD for median period of 12 months (range 0-48). On univariate analysis, intrahepatic recurrence rate of patients who underwent ENBD and/or ERBD (n=99) was higher than that of patients who did not (n=44) ( P=0.090) and and that of patients who had T3/T4 factor (n=74) was higher than that of who had T1/T2 factor (n=69) (P=0.168). Intrahepatic recurrence rateof patients who had elevated CA19-9 (&gt; 200) (n=49) was higher than that of patients who had not (n=94) ( P=0.002). In multivariate analyses, preoperative ENBD and/or ERBD and elevated serum CA19-9 level (&gt;200 ng/mL) were prognostic factors for intrahepatic recurrence, with hazard ratios (HR) of 2.154 (95% confidence interval (CI) 0.893-7.626, P = 0.080) and 3.647, (95% confidence interval (CI) 1.660-8.011, P = 0.001). Conclusions: Preoperative preoperative endoscopic nasal biliary drainage (ENBD) and/or endoscopic retrograde biliary drainage (ERBD) procedures may affect the intrahepatic recurrence of tumor in patient with cholangiocarcinoma after surgical resection. And serum elevated CA 19-9 level affected intrahepatic recurrence of tumor in patients with cholangiocarcinoma after surgical resection.
