Shared and specific competing endogenous RNAs network mining in four digestive system tumors

BackgroundDigestive system malignancies, including esophageal carcinoma (ESCA), stomach adenocarcinoma (STAD), liver hepatocellular carcinoma (LIHC), and colon adenocarcinoma (COAD), pose significant global health challenges. Identifying shared and distinct regulatory mechanisms across these cancers can lead to improved therapies. This study aims to construct and compare competing endogenous RNA (ceRNA) networks across ESCA, STAD, LIHC, and COAD to identify RNA biomarkers that could serve as precision therapeutic targets to enhance clinical outcomes and advance personalized cancer care. MethodsClinical and transcriptomic data from The Cancer Genome Atlas (TCGA) were analyzed to predict differentially expressed RNAs using edgeR package. The ceRNA networks were constructed using the miRcode and ENCORI databases. Functional enrichment analysis and prognostic RNA screening were performed with ConsensusPathDB and univariate Cox regression analysis. Resultswe identified 6, 88, 55, and 41 RNA biomarkers in ESCA, STAD, LIHC, and COAD, respectively. Network analysis revealed shared and specific elements, with shared nodes enriched in cell cycle and mitotic processes. Several biomarkers, including HMGB3 and RGS16 (ESCA), COL4A1 and COL6A3 (STAD), CDCA5 and CDCA8 (LIHC), and LIMK1 and OSBPL3 (COAD), were consistent with prior studies, while novel biomarkers, such as C3P1 (ESCA), P2RY6 (STAD), and N4BP2L1 and PPP1R3B (LIHC), were discovered. Based on RNA correlation analysis, 1, 23, and 2 potential ceRNA regulatory axes were identified in STAD (PVT1/miR-490-3p/HMGA2), LIHC (DLX6-AS1/miR-139-5p/TOP2A, etc.), and COAD (STRCP1 & LINC00488/miR-142-3p/GAB1), respectively. ConclusionsThis study advances the understanding of ceRNA networks in digestive cancers, highlighting RNA biomarkers with potential as therapeutic targets for personalized treatment strategies.

Metabolic Differences among Patients with Cirrhosis Using Q Exactive Hybrid Quadrupole Orbitrap Mass Spectrometry Technology.

The hospitalization and mortality rates of patients gradually increase following the onset and progression of liver cirrhosis (LC). We aimed to help define clinical stage and better target interventions by detecting the expression of specific metabolites in patients with different stages of LC via Q Exactive hybrid quadrupole orbitrap mass spectrometry (UPLC-Q-Exactive) technology. This noninterventional observation case-control study involved 139 patients with LC or acute-on-chronic liver failure (ACLF) in a Chinese hospital between October 2022 and April 2023. Serum specimens were analyzed for multiple metabolite levels using UPLC-Q-Exactive. Data were processed to screen for differentially accumulated metabolites (DAMs). Short time-series expression miner (STEM) analysis and enrichment analysis were performed to assess cirrhosis progression biomarkers. Following univariate and multivariate analyses, a Venn diagram indicated nine significant DAMs in common among groups. STEM analysis showed 8'-hydroxyabscisic acid, HDCA, pyruvate-3-phosphate, indospicine, eplerenone, and DEHP as significant; their levels first peaked [Child-Turcotte-Pugh (CTP) class B peaked] and then decreased with CTP grade aggravation. Significant differences among 8'-hydroxyabscisic acid, eplerenone, and DEHP were observed among LC comorbidities and between subgroups. Therefore, serum levels of six DAMs may characterize metabolomic changes, determine the severity of LC, and predict the development of ACLF.

Psychological distress among nurses: Exploring the role of support in the work-place in Morocco.

This study aimed to assess the psychological distress, specifically anxiety and depression, among nurses employed at University Hospital Center of Rabat in Morocco and tested the associations between support in the workplace and nurses' psychological well-being. A cross-sectional observational study was conducted at University Hospital Center of Rabat in Morocco, based on a prospective data collection employing an ad-hoc self-report questionnaire. 223 nurses were enrolled with a minimum of 1 year of practice in any care unit. Socio-demographic and professional characteristics of each participant were included. A validated tool was utilized to measure the support from superiors and colleagues in the workplace, while the Hospital Anxiety and Depression Scale (HADS) was employed to evaluate anxiety and depression. Univariate and multivariate analyses were conducted to explore the relationships between different independent and dependent variables. Significant socio-demographic and professional factors associated with increased anxiety included female gender, age over 41 years old, Baccalaureate level of education, intention to leave the hospital, and less support from superiors. Regarding the levels of depression, the Baccalaureate level of education was significantly associated with higher levels of depressive symptoms (β 2.444; CI [1.203, 3.686]). Our findings suggested that ensuring support from superiors was crucial for safeguarding the psychological well-being of nurses. Therefore, hospital managers should prioritize addressing the workplace support for professionals, and the organizational enhancement.

The Long-Term Results of Proximal Gastrectomy for Proximal Gastric Cancer: A Propensity Score Matching Analysis Based on SEER Database.

Proximal gastrectomy (PG) is one of function-preserving gastrectomy (FPG). In this study, we compared the long-term results of proximal gastric cancer (PGC) patients undergoing proximal gastrectomy and total gastrectomy (TG). Patients diagnosed with PGC and receiving PG or TG between 2004 and 2020 were selected from the Surveillance, Epidemiology, and End Results (SEER) database. Propensity score matching (PSM) was applied to minimize confounding factors. Kaplan-Meier analysis and log-rank test were used to compare overall survival (OS) and cancer-specific survival (CSS) between the PG and TG groups. Univariate and multivariate Cox regression analyses were performed to identify independent risk factors affecting OS. A total of 3916 patients were recruited according to the inclusion and exclusion criteria, with 2614 undergoing PG and 1302 undergoing TG. After 1:1 PSM matching, 912 pairs of data were included for analysis. Before PSM matching, PG group tended to have better OS and CSS outcomes. However, after PSM matching, both surgical approaches showed similar long-term results. PG for PGC yields comparable long-term outcomes to TG and demonstrates safety in terms of oncologic outcomes.

Clinical significance of peripheral blood DDR1 and CtBP gene methylation detection in patients with acute pancreatitis

ABSTRACT To investigate the clinical value of methylation levels of peripheral blood DDR1 and CtBP genes in evaluating the severity of acute pancreatitis (AP). Collect 90 blood samples from AP patients and healthy volunteers, and test methylation levels of SPINK1, STAT3, KIT, CFTR, DDR1, CtBP1, CtBP2 genes by bisulfite amplicon sequencing (BSAS). The gene methylation and clinical predictors of SAP early prediction were determined by univariate and multifactorial analysis, respectively. (1) The methylation level of CtBP1 gene and MCTSI score were independent predictors of SAP, with AUC values of 0.723 and 0.8895, respectively. (2) The methylation levels of DDR1, CtBP2, CFTR and SPINK1 genes were statistically significant in HC group vs AP group, HC group vs MAP group, and HC group vs SAP group. (3) The combined detection of CtBP1 gene methylation level and MCTSI score predicted the sensitivity, specificity, AUC, and 95%CI of SAP were 0.750, 0.957, 0.902, and 0.816–0.989, respectively. (1) The methylation level of CtBP1 gene in peripheral blood is an independent risk factor for predicting SAP and is a potentially good predictor of SAP, and the combined testing with the MCTSI score does not further significantly improve the early predictive value for SAP. (2) The methylation levels of DDR1, SPINK1, CtBP2, and CFTR genes were potential indicators for recognizing AP.

Prognostic Role of Pleural Fluid SUVpeak Value obtained from 18F-FDG PET/CT in patients with Malignant Pleural Effusion

PurposeAssessing the prognosis of patients with malignant pleural effusion (MPE) is cruical to manage the treatment. We aimed to investigate the role of pleural fluid SUVpeak value in predicting mortality. MethodsIn our single center, prospective cohort study, we enrolled 158 patients with MPE. PET/CT was independently evaluated by two nuclear medicine physicians. To identify independent predictors of 90-day mortality, we conducted both univariate and multivariate Cox regression analyses. Furthermore, we assessed the discriminatory ability of these predictors compared to the LENT score using the DeLong statistic. ResultsIn our study, we enrolled 158 patients with a mean age of 66.29±12.6 years, of whom 100 (63.3%) were male. The majority of patients (84.9%) had primary lung cancer, while 24 (15.1%) had metastases from extrapulmonary malignancies. Among the followed-up patients, 51 (32%) died within 90 days, with a median survival of 30 (17-61) days. LENT score (HR: 1.52, 95% CI: 1.14-2.03), pleural fluid albumin value (HR: 0.92, 95% CI: 0.87-0.97), pleural fluid SUVpeak value (HR: 1.39, 95% CI: 1.15-1.69), and pleural effusion size (HR: 1.01, 95% CI: 1.001-1.02) were found to be significant predictors. Furthermore, in assessing the predictive performance for 90-day mortality, ROC curve of a combination of the independent predictors was significantly higher than that of LENT score alone. ConclusionOur study revealed that the metabolic characteristics of pleural fluid might predict 90-day mortality in patients with MPE. We established that the incorporation of pleural fluid SUVpeak value into the LENT score has the potential to enhance its discriminative ability.

MRI-based Radiomics Virtual Biopsy for BCL6 in Primary Central Nervous System Lymphoma

AimTo establish machine learning model based on radiomic signature for predicting B-cell lymphoma 6 (BCL-6) rearrangement in primary central nervous system lymphoma (PCNSL). Materials and MethodsRetrospective study on 102 PCNSL patients (31 with BCL-6 rearrangement positive, 71 with BCL-6 rearrangement negative) were randomly divided into the training and validation set at a ratio of 7:3. Radiomics models based on contrast-enhanced T1-weighted imaging (CE-T1WI) and fluid-attenuated inversion recovery (FLAIR) in different regions including VOItumor core and VOIperitumoral edema. Radiomics features were extracted and selected using LASSO regression, and radiomics score (rad-score) were calculated using the weighted coefficients. Four machine learning models (logistic regression, random forest, support vector machine, K-nearest neighbors) were developed and evaluated based rad-score. The optimal radiomics model was integrated into the clinical or radiological factors to construct a predictive model through logistic regression analysis. A nomogram was constructed based on independent significant features for individualized prediction. ResultsAll rad-scores based on CE-T1WI and FLAIR sequences were significantly associated with BCL6 rearrangement (p<0.05) in univariate regression analysis. LR machine learning model performed best with AUCs of 0.935 (training) and 0.923 (validation). Rad-scores from CE-T1WI tumor core and peritumoral edema were independent significant predictors. ConclusionRadiomics signature based on CE-T1WI and FLAIR sequences have significant value in distinguishing BCL6 rearrangement. The CE-T1WI radiomics model based on VOItumor core and VOIperitumoral edema are robust markers for identifying BCL6 rearrangement.

Low handgrip strength as a marker of severity in the diagnostic criteria for cancer cachexia

Background & AimsThe diagnostic criteria for cachexia, as proposed by the Asian Working Group for Cachexia (AWGC), include weight loss, a low body mass index, and additional factors such as a low handgrip strength (HGS), anorexia, or elevated CRP levels. This study aimed to evaluate the significance of low HGS as a diagnostic criterion in patients with advanced cancer. MethodsThis single-centre, retrospective cohort study was conducted between April 2019 and March 2023. Patients aged ≥18 years with malignant diseases were included. Patients without records on HGS were excluded. Low HGS was defined as a HGS <28 kg for men and <18 kg for women. The overall median survival time (MST) was analysed by univariate and multivariate analyses. ResultsA total of 894 patients were analysed. Cachexia was prevalent in 74%, though only 3.4% were diagnosed based solely on low HGS. The MST in patients with cachexia was 122 days, and in those with low HGS was 73 days. The associations between low HGS and high mortality remained significant after adjusting for AWGC criteria, modified weight loss grading system, age, gender, performance status, calf circumferenceand fluid retention. The MST varied with the number of additional factors being met: 422 days for one criterion, 92 days for two, and 55 days for all three (p <0.0001). ConclusionThis study supports that HGS serve as important prognostic tool in patients with various cancers.

Predicting Pancreatic Cancer in New‐Onset Diabetes Cohort Using a Novel Model With Integrated Clinical and Genetic Indicators: A Large‐Scale Prospective Cohort Study

ABSTRACTIntroductionIndividuals who develop new‐onset diabetes have been identified as a high‐risk cohort for pancreatic cancer (PC), exhibiting an incidence rate nearly 8 times higher than the general population. Hence, the targeted screening of this specific cohort presents a promising opportunity for early pancreatic cancer detection. We aimed to develop and validate a novel model capable of identifying high‐risk individuals among those with new‐onset diabetes.MethodsEmploying the UK Biobank cohort, we focused on those developing new‐onset diabetes during follow‐up. Genetic and clinical characteristics available at registration were considered as candidate predictors. We conducted univariate regression analysis to identify potential indicators and used a 5‐fold cross‐validation method to select optimal predictors for model development. Five machine learning algorithms were used for model development.ResultsAmong 12,735 patients with new‐onset diabetes, 100 (0.8%) were diagnosed with PC within 2 years. The final model (area under the curve, 0.897; 95% confidence interval, 0.865–0.929) included 5 clinical predictors and 24 single nucleotide polymorphisms. Two threshold cut‐offs were established: 1.28% and 5.26%. The recommended 1.28% cut‐off, based on model performance, reduces definitive testing to 13% of the total population while capturing 76% of PC cases. The high‐risk threshold is 5.26%. Utilizing this threshold, only 2% of the population needs definitive testing, capturing nearly half of PC cases.ConclusionsWe, for the first time, combined clinical and genetic data to develop and validate a model to determine the risk of pancreatic cancer in patients with new‐onset diabetes using machine learning algorithms. By reducing the number of unnecessary tests while ensuring that a substantial proportion of high‐risk patients are identified, this tool has the potential to improve patient outcomes and optimize healthcare sources.

Significant Pathologic Response Following Neoadjuvant Therapy and Curative Resection in Patients With Rectal Cancer: Surgical and Oncological Outcomes From a Retrospective Cohort Study.

This study evaluated surgical complication rates, recurrence-free survival, overall survival (OS), and stoma status of patients with rectal cancer after significant pathologic response following neoadjuvant treatment and curative resection. Pathologic complete response (pCR) and near-pCR patients constitute patients in our study. Included was a retrospective cohort study of patients with rectal cancer who were diagnosed between July 2011 and September 2022 and who underwent neoadjuvant therapy and surgical resection. Of 696 patients with rectal cancer, 149 (21.4%) cases achieved significant pathologic response. During the 64 (70.5) months of follow-up, recurrence occurred in 16.1% of patients and distant metastases account for the majority of them. Age (p = 0.014) and receiving adjuvant chemotherapy (p = 0.016) were significantly related to the occurrence of recurrence. The five-year recurrence-free survival (RFS) and OS rates were obtained at 83% and 87%, respectively. Although age and surgical technique were significant factors in univariate Cox regression analysis, none of the candidate variables were significant prognostic factors for RFS in the multiple models. The risk of surgical complications remained in these patients. The most frequent complication attributed to infection (20.8%). Despite the 24.8% presence of permanent stoma at primary surgery, more than 50% of our patients lived without stoma at the last follow-up. Our recurrence rate was about 16%, and it was related to age and adjuvant chemotherapy. These patients achieved over 80% rates of five-year RFS and OS. No significant prognostic factors were found on RFS in the multivariable model. As a matter of course, the risk of surgical complications and permanent stoma has still remained in these patients.

The association between composite measures of social vulnerability and PICU admission for status asthmaticus

AbstractBackgroundCurrent knowledge of the impact of socioeconomic factors on the risk of admission to the pediatric intensive care unit (PICU) for asthma is limited. Using composite measures of social vulnerability—Social Vulnerability Index (SVI) and Child Opportunity Index (COI) 2.0—we compared patients admitted for status asthmaticus to the PICU and pediatric ward at Children's Hospital Los Angeles (CHLA). We hypothesized patients with a high SVI and low COI are at higher risk for PICU admission.MethodsPatients were identified using ICD‐10 codes for asthma. Primary outcome was admission to PICU versus ward for status asthmaticus. Patient‐registered residential street addresses were geocoded and spatially joined to SVI and COI 2.0 data at the census tract level. Univariate and regression analyses using the patient's SVI, COI 2.0, and admission location were conducted.ResultsFrom January 2017 to March 2022, there were 2458 admissions matched to addresses from 1983 distinct patients. The overall median SVI for all patients was 0.86 (IQR 0.6, 0.9). Overall median COI was 25.0 (IQR 10, 50). There was no difference in SVI or COI for admission to the PICU versus the ward. However, children requiring multiple hospital admissions for asthma were associated with higher SVI and lower COI.ConclusionsChildren admitted to CHLA for asthma had an elevated SVI and low COI. There was no difference between admission locations based on SVI or COI scores. This indicates we care for children at increased socioeconomic risk, but this did not increase PICU use for asthma.

The incidence, providers involved, and patient factors associated with diagnosis of specific lumbar spine pathology subsequent an initial nonspecific low back pain diagnosis

Background ContextLow back pain (LBP) is an exceedingly common diagnosis with significant societal and healthcare burden. While nonspecific LBP diagnoses are frequently assigned and often resolve soon thereafter, some patients may subsequently be diagnosed with specific underlying lumbar spine pathology. PurposeTo characterize the incidence, providers involved, and factors associated with specific pathology LBP (SP-LBP) diagnosed subsequent an initial nonspecific LBP (NS-LBP) diagnosis. Study DesignRetrospective cohort study. Patient SampleAdult patients diagnosed with NS-LBP between 2010 – Q1 2022 were abstracted from a large national administrative database. Outcome MeasurementsIncidence of subsequent SP-LBP diagnoses, providers involved, and factors associated with SP-LBP diagnoses in the 12-months following initial NS-LBP diagnosis. MethodsAdult patients diagnosed with NS-LBP were identified based on International Classification of Disease (ICD) codes ICD-9-D-724.2 and ICD-10-D-M54.5. These patients diagnosed with new NS-LBP were reported based on incidence per 100,000 covered lives. Exclusion criteria included: patients less than 18 years old, those with any prior NS-LBP diagnosis, any prior SP-LBP diagnoses, and those with trauma, neoplasm, or infection diagnosed within 3-months prior to the initial NS-LBP diagnosis. Patients who subsequently received SP-LBP diagnoses within 12-months following initial NS-LBP were then identified. Patients were characterized based on age, sex, history of cancer, obesity, opioid use disorder, anxiety, and depression and then compared with patients receiving no additional LBP diagnosis by univariable and multivariable analysis. Provider specialties who initially diagnosed NS-LBP and those involved with subsequent SP-LBP diagnoses were identified. ResultsNS-LBP was identified for a robust cohort of 6,861,235 patients, yielding an incidence of 4,258 diagnoses per 100,000 covered lives. Subsequent SP-LBP diagnoses were identified for 562,982 (8.21%) within 12-months, of which 62.57% of these SP-LBP diagnoses occurred within 3-months. The most common of these subsequent diagnoses included radiculopathy (3.01% of the overall study population), disc degeneration (2.84%), and disc herniation (1.23%). Patients receiving a subsequent SP-LBP diagnosis were more likely older (per year increase, odds ratio [OR] 1.02), male (OR 1.10), had a history of cancer (OR 1.32), obesity (OR 1.30), opioid use disorder (OR 1.17), anxiety (OR 1.21), or depression (OR 1.17) (p<0.001 for all). NS-LBP was initially diagnosed predominantly by primary care providers (PCPs) in family medicine (44.09%) and internal medicine (27.49%). These PCP providers also contributed to the majority of SP-LBP diagnoses, while specialty providers contributed to a greater degree in SP-LBP diagnoses than NS-LBP. ConclusionNS-LBP is a common diagnosis that usually, 91.79% of the time, does not subsequently convert to a SP-LBP diagnosis within 12-months. This may reflect improvement of LBP symptoms and/or accurate initial triage, largely by PCPs. Of the minority of patients receiving a subsequent SP-LBP diagnosis, various patient factors were significantly associated, and a greater degree of specialty providers were involved, which highlights potential contributors to diagnostic difficulty of SP-LBP and the multidisciplinary nature of LBP management.

Semaglutide utilization associated with reduced ninety-day postoperative complications following single-level posterior lumbar fusion for patients with type II diabetes

Background ContextSemaglutide (the active agent in medications such as Ozempic®) has emerged as an increasingly popular medication in the management of diabetes due to its superior clinical efficacy compared with other medications. Patients undergoing surgery, such as posterior lumbar fusion (PLF), may be on these medications for type II diabetes mellitus (T2DM). While the correlation of T2DM with inferior PLF outcomes is known, considering the potential impact of semaglutide on the odds of postoperative complications has not previously been characterized. PurposeTo investigate the potential correlation of semaglutide on 90-day postoperative adverse events following single-level PLF for those with T2DM who are or are not concurrently taking insulin. Study Design/SettingA retrospective cohort study utilizing the 2010 – Q2 2022 M161Ortho PearlDiver Mariner Patient Claims Database. Patient SampleT2DM patients (with or without concurrent insulin use) undergoing single-level PLF (with or without interbody fusion) were identified using Current Procedural Terminology (CPT) codes. Exclusion criteria included: patients less than 18 years of age, those undergoing concurrent cervical, thoracic, anterior, or multi-level fusion procedures, and those with trauma, neoplasm, or infection diagnosed within three months of surgery. Outcome MeasuresIncidence of 90-day aggregated any, severe, and minor adverse events (AAE, SAE, and MAE, respectively), emergency department (ED) visits, and hospital readmissions. MethodsPatients with a prior diagnosis of T2DM not using insulin (T2DM-insulin) and T2DM concurrently using insulin (T2DM+insulin) undergoing PLF were identified. Patients within each group who utilized semaglutide in the year prior to surgery were identified and matched 1:4 with non-semaglutide T2DM-insulin and non-semaglutide T2DM+insulin patients, respectively, based on age, sex, Elixhauser Comorbidity Index (ECI), obesity, tobacco use, metformin use, and sodium-glucose transport protein 2 inhibitor (SGLT2i) use. The incidence of 90-day adverse events between groups was compared by univariate and multivariate analyses. Bonferroni correction was utilized to reduce the risk of type I error. ResultsOf all T2DM patients undergoing PLF, semaglutide use was noted for 227 (0.73%) of T2DM-insulin patients, and 244 (2.17%) of T2DM+insulin patients. Once matched, there were 191 and 148 in the semaglutide groups, respectively.For the PLF T2DM-insulin analysis, those using semaglutide were at significantly lower odds of AAE (odds ratio [OR] 0.43), MAE (OR 0.45), and ED visits (OR 0.34) (p<0.001 for all), but not of SAEs or readmissions.For the PLF T2DM+insulin analysis, those using semaglutide were at significantly lower odds of AAE (OR 0.40, p<0.001), SAE (OR 0.43, p=0.004), MAE (OR 0.34, p<0.001), and ED visits (OR 0.26, p<0.001), but not readmissions. ConclusionsThe current study found consistent reductions in aggregated 90-day adverse events, but similar odds of hospital readmission for T2DM patients undergoing PLF taking semaglutide preoperatively. These encouraging findings of reduced postoperative complications suggest further prospective analysis, as the observed findings suggest clinical benefit to semaglutide being utilized by the studied patient population.

Prognostic Nomogram for Predicting Survival in Asian Patients With Small‐Cell Lung Cancer: A Comprehensive Population‐Based Study and External Verification

ABSTRACTBackgroundThe incidence of small cell lung cancer (SCLC) among Asian patients is on the rise. Nevertheless, there remains a deficiency in precise prognostic models tailored to the specific needs of this patient population. It is imperative to develop a novel nomogram aimed at forecasting the prognosis of Asian SCLC patients.MethodsThe SEER database supplied data on 661 Asian SCLC patients, who were then divided into training and internal validation sets through a random selection process. In addition, we identified 212 patients from a Chinese medical institution for the purpose of creating an external validation cohort. To forecast survival, we employed both univariate and multivariate analyses. The performance of our nomogram was assessed through calibration plots, the concordance index (C‐index), and decision curve analysis (DCA).ResultsFive independent prognostic factors were determined and integrated into the nomogram. C‐index values for the training and internal validation cohorts were 0.774 (95% confidence interval [CI] = 0.751–0.797) and 0.731 (95%CI = 0.690–0.772), respectively. In the external validation cohort, the C‐index is 0.712 (95% CI = 0.655–0.7692). Calibration curves demonstrated highly accurate predictions. When compared to the AJCC staging system, our model exhibited improved net benefits in DCA. Furthermore, the risk stratification system effectively differentiated patients with varying survival risks.ConclusionWe have created a novel nomogram for predicting the survival of Asian patients with SCLC. This nomogram has been subjected to external validation and has shown its superiority over the conventional TNM staging system. It offers a more precise and reliable means of forecasting the prognosis of Asian SCLC patients.

Predictors of Immediate Deterioration of the Child-Pugh Classification From A to B After Transcatheter Arterial Chemo-Embolization for Treatment-Naive Hepatocellular Carcinoma.

The purpose of this study was to evaluate the predictors of deterioration of the Child-Pugh classification 1 month after transcatheter arterial chemo-embolization (TACE) in patients with treatment-naive hepatocellular carcinoma (HCC). Between 2010 and 2020, consecutive patients who underwent conventional TACE using epirubicin as the initial treatment were enrolled. Patients with Barcelona Clinic Liver Cancer stage-0, A or B and Child-Pugh class A were included. The Child-Pugh score was evaluated before treatment and 1 month after TACE. The following variables were analyzed by univariate and multivariate analyses as predictors of deterioration of the Child-Pugh class from A to B: age, sex, etiology, serum albumin, bilirubin, prothrombin time (PT), encephalopathy, ascites, largest tumor diameter, tumor number, tumor location, α-fetoprotein, protein induced by vitamin K absence or antagonist-II, epirubicin dosage, ethiodized oil dosage, and number of treated liver segments. A total of 152 patients were retrospectively enrolled. The deterioration rate of the Child-Pugh class from A to B was 8.6%. Multivariable analysis showed that serum albumin ≤ 3.8 g/dL, PT ≤ 80%, and largest tumor diameter ≥ 3.8 cm were predictors of deterioration of the Child-Pugh class. The deterioration rate to Child-Pugh class B was 0% in patients with up to one of these factors, 14.3% in those with two factors, and 70% in those with three factors. A combination of serum albumin ≤ 3.8 g/dL, PT ≤ 80%, and largest tumor diameter ≥ 3.8 cm can predict the immediate deterioration of the Child-Pugh classification from A to B following TACE.

Diagnostic accuracy of ultrasound classifications – O-RADS US v2022, O-RADS US v2020, and IOTA SR – in distinguishing benign and malignant adnexal masses: Enhanced by combining O-RADS US v2022 with tumor marker HE4

PurposeTo assess the diagnostic accuracy of O-RADS Ultrasound (O-RADS US) v2022, O-RADS US v2020, and IOTA SR, and to evaluate whether combining imaging findings with tumor markers enhances the diagnosis of adnexal masses. MethodsThis retrospective study, conducted between January 2018 and December 2023, included consecutive women with adnexal masses scheduled for surgery. Histopathologic results served as the reference standard. Risk factors for malignancy were identified using univariate and multivariate logistic regression analyses. ROC analysis was employed to assess diagnostic test performances, while Kappa statistics evaluated inter-reviewer agreement. ResultsA total of 613 women (mean age, 49.39 ± 12.81 years; range, 16–87 years) with pelvic masses were included. O-RADS US v2022 exhibited comparable performance to O-RADS US v2020, with areas under the curve (AUC) values of 0.940 and 0.937, respectively (p = 0.02, exceeding the adjusted significance level of 0.0167). Both O-RADS models outperformed the IOTA SR, which had an AUC of 0.862 (p < 0.0001 for both comparisons). Multivariate analysis revealed that O-RADS US v2022 [OR 9.148, 95 %CI (4.912–17.039), p < 0.001] and HE4 [OR 1.023, 95 %CI (1.010–1.036), p = 0.001] were significant factors associated with malignant lesions. Furthermore, the combination of O-RADS US v2022 and HE4 demonstrated an AUC of 0.98, significantly outperforming either O-RADS US v2022 alone (AUC = 0.94) or HE4 alone (AUC = 0.92). The Kappa values for O-RADS US v2022, O-RADS US v2020 and IOTA SR were 0.933, 0.891 and 0.923, respectively, indicating substantial inter-reader agreement. ConclusionsThe O-RADS US v2022 demonstrates comparable performance in predicting ovarian malignant lesions when compared to O-RADS US v2020, while surpassing the performance of IOTA SR. Additionally, the combination of O-RADS US v2022 and HE4 provides improved diagnostic effectiveness over using either O-RADS US v2022 or HE4 alone.

Comparison of prognosis after transurethral resection of bladder tumor between solitary and multiple bladder cancers.

This study investigates the difference in overall survival rates after transurethral resection of bladder tumor between solitary and multiple bladder cancers, aiming to provide guidance for clinical practitioners. A retrospective analysis was conducted on 133 patients with bladder cancer who underwent transurethral resection of bladder tumor from April 2017 to October 2023, of which 112 patients had complete clinical and follow-up data. Clinical and follow-up data were collected, and the overall survival rates after surgery were compared between solitary and multiple bladder cancers. In this study, the recurrence rate after transurethral resection of bladder tumor was 23.21% (26/112), and the overall survival rate was 80.36% (90/112). The overall survival rate after transurethral resection of bladder tumor was 92.11% (35/38) in the solitary bladder cancer group and 74.32% (55/74) in the multiple bladder cancer group, with a statistically significant difference between the 2 groups (P = .025). The proportion of high-grade pathology was 7.89% (3/38) in the solitary bladder cancer group and 25.68% (19/74) in the multiple bladder cancer group after transurethral resection of bladder tumor, with a statistically significant difference between the 2 groups (P = .025). The mean tumor diameter after transurethral resection of bladder tumor was 2.76 ± 1.66 cm in the solitary bladder cancer group and 4.04 ± 3.17 cm in the multiple bladder cancer group, with a statistically significant difference between the 2 groups (P = .023). Univariate and multivariate regression analyses revealed that the number of bladder tumors is a risk factor for overall survival after bladder cancer surgery (P = .004). Multiple bladder cancers have a higher pathological grade, larger tumor diameter, and poorer prognosis after transurethral resection of bladder tumor compared to solitary bladder cancers. The number of bladder tumors is an independent risk factor for overall survival after bladder cancer surgery.

Breastfeeding practices amongst immigrants living in Finland: results from the FinChildren survey

BackgroundBreastfeeding is a corner of child health and survival as it provides crucial, non-replaceable nourishment necessary for infant's growth and development . Immigration has been shown to influence breastfeeding particularly among immigrants from low-and-middle-income countries. Our aim was to examine breastfeeding practices and sociodemographic characteristics of Somali/Arabic and Russian speaking in comparison with Finnish speaking mothers. MethodsWe analyzed data from 5348 mothers with infants who participated in FinChildren survey conducted in 2020. Univariate and multivariate analysis was used to estimate the association between maternal origin and breastfeeding practices by comparing immigrant mothers and native-born mothers. ResultsSomali/Arabic-speaking mothers were younger, less educated and had higher BMI than Russian and native Finnish speaking mothers. Proportions of exclusive breastfeeding at 4-5 months of age were lowest among Somali/Arabic speaking mothers (21 %) compared to native-born (49 %) and to Russian-speaking mothers (52%) Again, Somali/Arabic-speaking mothers had the highest proportions of mixed feeding (66%) compared to native Finnish-speaking (38 %) and Russian-speaking mothers (32%) Being a Somali/Arabic-speaking mother decreased the odds of exclusive breastfeeding (OR 0.20, 95% CI 0.10-0.45) and quadrupled (OR 4.0, 95% CI 2.18-7.37) the odds of mixed feeding at 4-5 months of age. ConclusionEven though the number of immigrant mothers was low, this study suggests that maternal origin is a significant predictor of suboptimal breastfeeding independent of sociodemographic and antenatal characteristics. There is a need for culturally sensitive interventions to promote breastfeeding among these groups.

Clinical characteristics and outcomes of Takotsubo syndrome in patients with chronic obstructive pulmonary disease

Backgroundtakotsubo syndrome (TTS) is an acute heart failure syndrome characterized by a relevant comorbid background, including chronic obstructive pulmonary disease (COPD). However, TTS patients with COPD are still not well characterized. Aimto describe the clinical characteristics and outcomes of patients with TTS and COPD. Methodsn = 440 TTS patients were dichotomized according to the presence of COPD. Endpoint of the study were in-hospital complications (composite of death, major arrhythmias, cardiogenic shock and acute pulmonary edema), TTS recurrence and long-term mortality at follow-up. Resultsmean age of the population was 72±11, 10 % males. COPD prevalence was 16 % (n = 69). On subgroup analysis, patients with COPD were more likely smokers (41 % vs 13 %, p < 0.001), with higher rates of dyspnea and physical triggers at presentation (52 % vs 18 %, p < 0.001 and 52 % vs 32 %, p = 0.001 respectively) and lower left ventricular ejection fraction (36 % vs 39 %, p = 0.035) In-hospital complications were more common in patients with COPD (26 % vs 13 %, p = 0.006), driven by higher rates of acute pulmonary edema (19 % vs 6 %, p < 0.001) and cardiogenic shock (10 % vs 4 %, p = 0.023). At multivariable logistic regression analysis, COPD was independently associated with in-hospital complications occurrence (Odds Ratio 2.10, 95 % CI 1.09–4.05; p = 0.027). At univariable Cox regression analysis COPD was associated with TTS recurrence (Hazard Ratio (HR 9.82, 95 % CI 3.2–30.12; p < 0.001)), at multivariable Cox regression analysis with long-term mortality (HR 2.97, 95 % CI 1.44–6.12; p = 0.003). ConclusionCOPD marks a vulnerable TTS phenotype including higher risk of in-hospital complications, long-term recurrence and mortality.

Comparison of survival times of cats with hyperthyroidism treated with thyroidectomy or methimazole at a primary care hospital in Japan.

We identified the associated factors and compared the survival times of feline hyperthyroidism (FHT) between thyroidectomy and methimazole alone. The medical records of 41 cats diagnosed with new-onset hyperthyroidism were retrospectively reviewed. The cats were categorized into the thyroidectomy (n = 15) and methimazole (26) treatment groups. Survival analyses using the Kaplan-Meier method, log-rank test, and Cox proportional hazards models were conducted to compare the time to the selected outcomes. Univariate analysis revealed that survival time was significantly longer with thyroidectomy than with methimazole (P < .001). Multivariate analyses revealed thyroidectomy as an independent prognostic factor for good outcomes (hazard ratio, 0.209; 95% CI, 0.073 to 0.601; P = .004). The recurrence rate was significantly lower in cats that underwent thyroidectomy than in those that received methimazole alone (P = .011). Compared with methimazole alone, thyroidectomy was associated with a longer survival time in FHT and can be considered an irreversible treatment modality in settings where radioisotopes are not available.
