Sex differences in muscle-invasive bladder cancers: A study of a French regional population

ObjectivesAlthough men have a higher risk of developing a bladder cancer, women appear to have a poorer prognosis and a more advanced stage at diagnosis. We performed a retrospective population-based study on muscle invasive bladder cancer (MIBC) using data from a cancer registry in a French department to compare overall and specific survival data according to sex. Material and methodsWe included all patients living in the department of Hérault and diagnosed with MIBC between January 1, 2017 and December 12, 2019. Univariable and multivariable analyses were performed on all variables of interest. ResultsWe included 124 women and 432 men. There was no significant difference in age or stage at diagnosis according to sex. Squamous cell carcinomas were more common in women (P<0.001). Cystectomy was more frequent in men than in women (50.7% vs 35.4%) (P=0.0039). By multivariable analysis, the independent factors for being treated by cystectomy were sex (P=0.004), age (P<0.001) and stage (P<0.001). Forty-seven percent of women received no treatment or palliative treatment. Overall mortality was 79% in women and 63.2% in men (P<0.001). The median specific survival was 10.8months in women and 32.7months in men (P<0.0001). By multivariable analysis, the independent risk factors for mortality were female sex (P=0.047), cT4 stage (P=0.005) and absence of cystectomy (P<0.001). ConclusionsOur study shows that women are less often treated with cystectomy and have worse prognosis than men. The reasons for this gender difference are multifactorial.

Low platelet to high-density lipoprotein ratio predicts poor short-term prognosis in hepatitis B-related acute-on-chronic liver failure

BackgroundAcute-on-chronic liver failure (ACLF) is characterized by a systemic inflammatory response, predominantly associated with hepatitis B virus in the Asia-Pacific region, with a high short-term mortality rate. The platelet to high-density lipoprotein ratio (PHR) has been used to predict the prognosis of patients with various inflammatory diseases. We aim to is to use the PHR to predict the short-term prognosis of patients with HBV-ACLF.MethodIn this study, we retrospectively analyzed clinical data from 270 HBV-ACLF patients. Using logistic regression, we identified independent risk factors for short-term mortality and developed a prognostic model. This model was then validated, compared, and its clinical utility assessed via decision curve analysis (DCA).ResultsAmong the 270 HBV-ACLF patients, 98 patients died within 28 days. The deceased group exhibited a higher proportion of severe hepatic encephalopathy and ascites. Additionally, there was a statistically significant difference (P = 0.046) in the novel inflammation scoring system, PHR, between the two groups. Following stringent variable selection, PHR was identified as a predictive factor for short-term mortality in HBV-ACLF patients using logistic regression analysis (OR: 0.835 (0.756–0.999), P = 0.009), and it exhibited a synergistic effect with certain traditional scores. The prognostic model constructed based on PHR demonstrated a superior ability to predict short-term mortality compared to traditional scores such as Child-Turcotte-Pugh (AUC: 0.889). Evaluation using calibration curves and decision curve analysis (DCA) suggested its practical utility.ConclusionPHR can predict short-term mortality in patients, with a low PHR upon admission being associated with an increased risk of death.

Mortality risk of patients with intestinal obstruction

BackgroundIntestinal obstruction represents a severe intestinal disease associated with higher mortality rates. However, the determinants of mortality in patients with intestinal obstruction remain inadequately understood. This study sought to elucidate the potential risk factors associated with mortality in the context of intestinal obstruction during the COVID-19 pandemic.MethodsA retrospective analysis was performed on a cohort of 227 patients diagnosed with intestinal obstruction at the First Hospital of Hebei Medical University, spanning the period from September 7, 2022, to January 7, 2023. The primary endpoint of the study was mortality within four weeks following discharge. Univariate and multivariable logistic regression models were utilized to evaluate the risk factors associated with mortality outcomes.ResultsA cohort of 227 patients diagnosed with intestinal obstruction (median age, 59.02 years [IQR, 48.95–70.85 years]) was included in our study. Malignant bowel obstruction (MBO) and COVID-19 were identified as independent risk factors for mortality among these patients. Notably, the mortality rate increased significantly to 38.46% when MBO was concomitant with COVID-19. Furthermore, postoperative pulmonary complications (PPC) (OR, 54.21 [death]; 95% CI, 3.17-926.31), gastric cancer (OR, 9.71 [death]; 95% CI, 1.38–68.18), VTE (Caprini Score ≥ 5) (OR, 7.64 [death]; 95% CI, 1.37–42.51), and COVID-19 (OR, 5.72 [death]; 95% CI, 1.01–32.29) were all determined to be independent risk factors for postoperative mortality. Additionally, gastric cancer could have emerged as one of the most severe risk factors for mortality in individuals with intestinal obstruction within the cohort of cancer patients, of which gastric cancer exhibited higher mortality rates compared to individuals with other forms of cancer.ConclusionThe study identifies MBO, gastric cancer, COVID-19, PPC, and VTE as potential risk factors for mortality in cases of intestinal obstruction. These findings highlight the necessity for continuous monitoring of indicators related to these mortality risk factors and their associated complications, thereby offering valuable insights for the management and treatment of intestinal obstruction.

Retrospective ANalysis of multi-drug resistant Gram-nEgative bacteRia on veno-venous extracorporeal membrane oxygenation. The multicenter RANGER STUDY

BackgroundVeno-venous extracorporeal membrane oxygenation (V-V ECMO) is a rapidly expanding life-support technique worldwide. The most common indications are severe hypoxemia and/or hypercapnia, unresponsive to conventional treatments, primarily in cases of acute respiratory distress syndrome. Concerning potential contraindications, there is no mention of microbiological history, especially related to multi-drug resistant (MDR) bacteria isolated before V-V ECMO placement. Our study aims to investigate: (i) the prevalence and incidence of MDR Gram-negative (GN) bacteria in a cohort of V-V ECMOs; (ii) the risk of 1-year mortality, especially in the case of predetected MDR GN bacteria; and (iii) the impact of annual hospital V-V ECMO volume on the probability of acquiring MDR GN bacteria.MethodsAll consecutive adults admitted to the Intensive Care Units of 5 Italian university-affiliated hospitals and requiring V-V ECMO were screened. Exclusion criteria were age < 18 years, pregnancy, veno-arterial or mixed ECMO-configuration, incomplete records, survival < 24 h after V-V ECMO. A standard protocol of microbiological surveillance was applied and MDR profiles were identified using in vitro susceptibility tests. Cox-proportional hazards models were applied for investigating mortality.ResultsTwo hundred and seventy-nine V-V ECMO patients (72% male) were enrolled. The overall MDR GN bacteria percentage was 50%: 21% (n.59) detected before and 29% (n.80) after V-V ECMO placement. The overall 1-year mortality was 42%, with a higher risk observed in predetected patients (aHR 2.14 [1.33–3.47], p value 0.002), while not in ‘V-V ECMO-acquired MDR GN bacteria’ group (aHR 1.51 [0.94–2.42], p value 0.090), as compared to ‘non-MDR GN bacteria’ group (reference). Same findings were found considering only infections. A larger annual hospital V-V ECMO volume was associated with a lower probability of acquiring MDR GN bacteria during V-V ECMO course (aOR 0.91 [0.86–0.97], p value 0.002).Conclusions21% of MDR GN bacteria were detected before; while 29% after V-V ECMO connection. A history of MDR GN bacteria, isolated before V-V ECMO, was an independent risk factor for mortality. The annual hospital V-V ECMO volume affected the probability of acquiring MDR GN bacteria.Trial Registration ClinicalTrial.gov Registration Number NCTNCT06199141, date 12.26.2023.

Outcomes after open and endovascular treatment for mesenteric artery embolism patients: a retrospective inverse probability of treatment-weighted analysis.

This study aims to evaluate outcomes in patients with mesenteric artery embolism (MAE) who received primary endovascular therapy (EVT) or laparotomy, and investigate risk factors for 30-day mortality. A retrospective analysis of 94 MAE patients who underwent two different treatment strategies was undertaken. An inverse probability of treatment weighting (IPTW) method was used to balance the confounding effects of baseline clinical data. Logistic regression analysis was performed to compare the outcomes according to type of treatment regimens before and after IPTW. Univariate and multivariable analysis were conducted to determine the risk factors for 30-day mortality. Twenty-eight MAE patients received primary EVT, and 66 Open Surgery (OS). Logistic regression analysis showed that there was no significant difference between the EVT and OS group in 30-day mortality rate before (odds ratio [OR] 0.477, 95% confidence interval [CI] 0.170 to 1.340, P = 0.160), and after IPTW (OR 0.647, 95% CI 0.210 to 1.993, P = 0.449). After IPTW, it revealed that the rates of second-look surgery (OR 36.727, 95% CI 5.407 to 249.458, P < 0.001) and hospital stay [> 30 days] (OR 0.006, 95% CI 0.000 to 0.363, P = 0.014) were different in the two groups. D-dimer (> 4mg/L) and procalcitonin (> 0.5 ng/mL) were the independent risk factors for 30-day mortality in MAE patients postoperatively (P < 0.05). In this retrospective study, MAE patients who performed primary EVT had no obvious difference in 30-day mortality rate compared to those who received OS; but it was conducive to reducing prolonged hospital stays. An increase in procalcitonin level and higher D-dimer were associated with short-term poor prognosis in patients with MAE.

Advancements in nutritional diagnosis and support strategies during the perioperative period for patients with liver cancer.

Liver cancer represents a grave hepatic condition and constitutes a significant global health concern. Surgical resection remains the principal therapeutic modality for liver cancer. Nevertheless, perioperative malnutrition exerts a notable impact on patients with liver cancer, emerging as an independent risk factor for disease mortality and adverse outcomes. Hence, precise nutritional diagnosis and timely nutritional support hold the potential to enhance therapeutic efficacy and quality of life for liver cancer patients. This study represents a meticulous foray into the literature, extracting data from PubMed, Web of Science, and EMBASE databases, with a focus on the past 5 years. It scrutinizes the impact of malnutrition on patients undergoing liver cancer surgery, the etiological underpinnings of malnutrition within this patient cohort, the critical assessment of perioperative nutritional status, and the strategic approaches to nutritional support. Utilizing rigorous inclusion and exclusion criteria, the amassed scholarly works are meticulously synthesized, methodically organized, and categorically elaborated upon. Ultimately, the authors propose the incorporation of a multidisciplinary nutrition management team during the perioperative period, comprising nutritionists, pharmacists, physicians, nurses, psychologists, and rehabilitation therapists, among other specialized professionals. Together, they collaborate to devise and implement personalized nutritional support plans, monitor patients' nutritional status, and make necessary adjustments as required. Through comprehensive management and intervention, improvements in the nutritional status of liver cancer patients can be achieved, thereby enhancing surgical success rates and facilitating postoperative recovery. It is believed that this manuscript will offer valuable insights to advance the nutritional management during the perioperative phase of liver cancer, aiding in ameliorating patients' nutritional status and treatment outcomes.

Risk factors for postoperative mortality within 1 year in more than 90-year-old super advanced age patients with hip fractures

To investigate the 1 year mortality after hip fractures in super advanced age patients and summarize the death associated risk factors in order to provide basis for targeted intervention countermeasures. The clinical data of 332 super advanced age patients with femoral neck or intertrochanteric fractures treated by hip replacement or intramedullary femoral nail fixation from January 2015 to January 2023 were retrospectively analyzed. There were 128 males and 204 females with the mean age of (92.2±2.5) years ranging from 90 to 103 years old. Among them, 92 cases died within 1 year after surgery. Correlation with the occurrence of death on age, gender, body mass index, fracture type, treatment method, timing of operation, preoperative hemoglobin and serum albumin level, operation time, combined medical diseases, pre-injury mobilityand American Society of Anesthesiology(ASA) classification were analyzed. The risk factors of death within 1 year after operation were screened by univariate analysis. The results were entered into the multivariate Logistic regression analysis, screening the high risk factors for 1 year mortality after hip fractures. The mortality of super advanced age patients with hip fracture within 1 year after surgery accounted for 27.7%(92/332). Univariate analysis showed high body mass index, long interval from injury to surgery, low preoperative serum albumin levels, inability to walk independently before injury, accompanied by heart failure, pulmonary infection, obstructive pulmonary disease, stroke, and a higher proportion of ASA grades Ⅲ-Ⅳ. Multivariate Logistic regression analysis showed preoperative serum albumin below 30g g·L-1[OR=2.973, 95%CI(2.461, 5.344), P=0.039], inability to walk independently before injury [OR=3.519, 95%CI(2.224, 5.413), P=0.018], heart function grade C-D[OR=4.213, 95%CI(2.952, 6.99), P=0.021], pulmonary infection[OR=3.927, 95%CI(2.187, 7.731), P=0.016] and ASA Ⅲ-Ⅳ[OR=5.124, 95%CI(3.092, 8.235), P=0.032] were the independent risk factors for death within 1 year in super advanced age patients with hip fractures. Preoperative serum albumin below 30g.L-1, poor preinjury activity, heart function grade C-D, pulmonary infection, and ASA grade Ⅲ-Ⅳ are independent risk factors for postoperative mortality in super advanced age patients with hip fractures.

A nomogram including admission serum glycated albumin/albumin ratio to predict mortality in patients with severe fever with thrombocytopenia syndrome

BackgroundSevere fever with thrombocytopenia syndrome (SFTS) is a novel tick-borne infectious disease with a high fatality rate. Although several nomograms based on demographic and laboratory data have been reported to predict the prognosis of SFTS in recent studies, baseline serum glycated albumin (GA)/albumin (ALB) ratio included risk model has not been evaluated for the prediction of clinical outcome.MethodsA total of 214 SFTS patients with integral data admitted to our hospital from May, 2020 to November, 2022 were included in this study. SFTS infection was confirmed by real time fluorescent quantitative PCR (qRT-PCR). The demographic characteristics, clinical and laboratory data were collected with in 24 h of admission and 1 to 2 days before discharge and were analysed retrospectively.ResultsFiffty-seven patients (26.6%) died. Multivariate logistic regression analysis showed that age, aspartate aminotransferase (AST), blood glucose (GLU), GA/ALB ratio, neutrophil counts (NEU) and lymphocyte percentage (LYM%) were the independent risk factors for mortality. A nomogram by these factors was created using RMS package in the R program. Area under the receiver operating characteristic (ROC) curve (AUC) of this nomogram was 0.88 (95% CI: 0.83, 0.93). This model showed the excellent net benefit, as revealed by the decision curve analysis. GA/ALB ratios were also independent risk factors for poor out clinical come in subgroups of patients with hyperglycemia on admission and with diabetes history. Nomograms were constructed by the independent risk factors in the subgroups. AUCs of the nomograms in the subgroups showed high predictive values for adverse prognosis.ConclusionsGA/ALB ratios were independent risk factors for mortality in all SFTS patients and subgroups of with hyperglycemia on admission and diabetes history. The nomograms including GA/ALB ratio had high predictive value for adverse clinical outcome.The nomograms provide a basis for clinical decision-making for the treatment of SFTS patients in different clinical settings.

Observational study of in-hospital mortality risk from bladder cancer: Five years of experience at a tertiary referral hospital in Indonesia.

Bladder cancer (BC) is a neoplasm arising from the bladder. It requires appropriate management and its prognosis depends on many factors. This study aimed to analyze the factors that influence outcomes in BC management. This was a retrospective study. Data were collected at one of Indonesia's largest tertiary referral hospitals. All patients diagnosed with BC from January 2019 to December 2023 were included. The outcome measured was survival or death. Statistical analysis was conducted using SPSS version 26.0 software. The study included 219 patients with a median age of 57.97 years, of which 99 (45.2 %) patients died. In a bivariate analysis, sex, active smoking status, Karnofsky score, metastasis status, chronic kidney disease, type 2 diabetes mellitus, chemotherapy, radiotherapy, and alternative medicine were found to affect mortality status. Based on multivariate analysis, the route of admission (odds ratio [OR] 0.19), irregular visit (OR 6.21), metastasis (OR 3.58), radiotherapy (OR 21.12), and traditional medicine (OR 0.21) were independent factors of in-hospital mortality. The mortality rate for BC was considerably high. Irregular visits, metastasis, type 2 diabetes, and radiotherapy were independent risk factors for mortality.

Neutrophil to lymphocyte ratio and five-year mortality in patients with acute ischemic stroke

BackgroundPrevious studies linked neutrophil to lymphocyte ratio (NLR) with short-term mortality after acute ischemic stroke (AIS), but its relationship with long-term mortality remains unclear. This study investigates the association between NLR and five-year mortality in AIS patients. MethodWe analyzed 416 AIS patients from April 2012 to January 2016 at Zhangjiagang TCM Hospital. Admission NLR was divided into quartiles: Q1 (<2.00), Q2 (2.00–3.05), Q3 (3.06–5.46), and Q4 (≥5.46). We assessed 5-year all-cause and vascular mortality using Kaplan-Meier, Cox regression, and receiver operating characteristic (ROC) curve analyses. ResultsOver five years, 134 (32.2 %) all-cause deaths and 114 (27.4 %) vascular deaths occurred. Elevated NLR was significantly associated with increased risks of all-cause and vascular mortality. Multivariate Cox analysis identified stroke history (HR: 1.57, 95 % CI 1.08–2.30), baseline National Institutes of Health Stroke Scale (NIHSS) score (HR: 1.09, 95 % CI 1.05–1.12), and NLR (HR: 1.09, 95 % CI 1.05–1.12) as independent risk factors for all-cause mortality. These factors also predicted 5-year vascular mortality: stroke history (HR: 1.65, 95 % CI 1.10–2.49), NIHSS score (HR: 1.10, 95 % CI 1.06–1.13), and NLR (HR: 1.08, 95 % CI 1.05–1.10). NLR quartiles were significantly linked to both outcomes: all-cause mortality HRs were Q2 (1.87, 95 % CI 1.00–3.51), Q3 (2.40, 95 % CI 1.31–4.39), Q4 (2.77, 95 % CI 1.47–5.24), P for trend = 0.001; vascular mortality HRs were Q2 (1.76, 95 % CI 0.88–3.55), Q3 (2.34, 95 % CI 1.14–4.40), Q4 (2.57, 95 % CI 1.28–5.16), P for trend = 0.002. Kaplan-Meier survival analysis revealed significantly higher mortality rates in higher NLR quartiles (log-rank p < 0.001). ROC analysis identified optimal NLR cutoff values of 3.42 for predicting 5-year all-cause mortality (AUC 0.689) and 3.51 for vascular-cause mortality (AUC 0.700), with moderate sensitivity and specificity. ConclusionsHigher NLR at admission was linked with five-year all-cause mortality and mortality attributed explicitly to vascular causes in AIS patients.

Association of changes in body composition with all-cause mortality in patients undergoing hemodialysis: A prospective cohort study

ObjectivesThis study aimed to explore the effect of longitudinal body composition changes on mortality risk in patients undergoing hemodialysis and identify whether changes in body composition can more accurately predict mortality than baseline status. MethodsA prospective cohort study was conducted on 340 patients undergoing hemodialysis. Lean mass and body fat were determined using a bioimpedance spectroscopy (BIS) device and expressed as the lean tissue index (LTI) or fat tissue index (FTI), respectively. The patients were subjected to BIS at baseline and after 1 year. The hazard ratio (HR) for death was calculated using Cox regression analysis. ResultsAmong 340 patients, 289 were tested with a repeat BIS. LTI loss and FTI gain were observed in 51.2% and 47.1% of the patients, respectively. Low baseline LTI was a significant predictor of all-cause mortality after adjusting for demographic and biochemical parameters (HR, 2.41; P = 0.047), but not when comorbidities were included in the multivariate analysis. However, after adjusting for various confounding factors, LTI loss (HR, 3.40; P = 0.039) and FTI gain (HR, 4.06; P = 0.024) were independent risk factors for all-cause mortality, and the adjusted HR for LTI loss and FTI gain vs. no LTI loss and no FTI gain was 5.34 (P = 0.016). ConclusionsLTI loss and FTI gain, particularly their combination, are important predictors of survival in patients undergoing hemodialysis. Our results emphasize that longitudinal changes in LTI and FTI are more strongly associated with all-cause mortality than single-point values. Therefore, it is important to dynamically assess the muscle and fat tissues and develop potential targeted treatment strategies for this population.

Can antibiotics affect the clinical features of patients with candidemia? The retrospective evaluation of 5 years of data in an intensive care unit

BackgroundCandidemia is an opportunistic infection of intensive care units (ICUs) and causes morbidity and mortality. Multiple antibiotic exposure was found to be an independent risk factor for mortality and non-albicans...

Retrospective analysis of molecular characteristics, risk factors, and outcomes in carbapenem-resistant Klebsiella pneumoniae bloodstream infections

BackgroundKlebsiella pneumoniae (KP) is the second most prevalent Gram-negative bacterium causing bloodstream infections (BSIs). In recent years, the management of BSIs caused by KP has become increasingly complex due to the emergence of carbapenem-resistant Klebsiella pneumoniae (CRKP). Although numerous studies have explored the risk factors for the development of CRKP-BSIs, the mortality of patients with KP-BSIs, and the molecular epidemiological characteristics of CRKP, the variability in data across different populations, countries, and hospitals has led to inconsistent conclusions. In this single-center retrospective observational study, we utilized logistic regression analyses to identify independent risk factors for CRKP-BSIs and factors associated with mortality in KP-BSI patients. Furthermore, a risk factor-based prediction model was developed. CRKP isolates underwent whole-genome sequencing (WGS), followed by an evaluation of microbiological characteristics, including antimicrobial resistance and virulence genes, as well as epidemiological characteristics and phylogenetic analysis.ResultsOur study included a total of 134 patients with KP-BSIs, comprising 50 individuals infected with CRKP and 84 with carbapenem-susceptible Klebsiella pneumoniae (CSKP). The independent risk factors for CRKP-BSIs were identified as gastric catheterization (OR = 9.143; CI = 1.357–61.618; P = 0.023), prior ICU hospitalization (OR = 4.642; CI = 1.312–16.422; P = 0.017), and detection of CRKP in non-blood sites (OR = 8.112; CI = 2.130-30.894; P = 0.002). Multivariate analysis revealed that microbiologic eradication after 6 days (OR = 3.569; CI = 1.119–11.387; P = 0.032), high Pitt bacteremia score (OR = 1.609; CI = 1.226–2.111; P = 0.001), and inappropriate empirical treatment after BSIs (OR = 6.756; CI = 1.922–23.753; P = 0.003) were independent risk factors for the 28-day mortality in KP-BSIs. The prediction model confirmed that microbiologic eradication after 6.5 days and a Pitt bacteremia score of 4.5 or higher were significant predictors of the 28-day mortality. Bioinformatics analysis identified ST11 as the predominant CRKP sequence type, with blaKPC−2 as the most prevalent gene variant. CRKP stains carried multiple plasmid-mediated resistance genes along with some virulence genes. Phylogenetic analysis indicated the presence of nosocomial transmission of ST11 CRKP within the ICU.ConclusionsThe analysis of risk factors for developing CRKP-BSIs and the association between KP-BSIs and 28-day mortality, along with the development of a risk factor-based prediction model and the characterization of CRKP strains, enhances clinicians’ understanding of the pathogens responsible for BSIs. This understanding may help in the timely administration of antibiotic therapy for patients with suspected KP-BSIs, potentially improving outcomes.

Prognostic Value of Dynamic Segmented Neutrophil to Monocyte (SeMo) Ratio Changes in Patients with Moderate to Severe Traumatic Brain Injury.

Traumatic brain injury (TBI) is a leading cause of morbidity and mortality in trauma patients, necessitating reliable prognostic tools. The segmented neutrophil-to-monocyte (SeMo) ratio, indicative of the inflammatory response, has emerged as a valuable biomarker. This study evaluates the prognostic value of dynamic changes in the SeMo ratio in predicting outcomes for patients with moderate to severe TBI. A retrospective analysis was conducted on data from 1118 TBI patients admitted to the surgical intensive care unit at a level I trauma center between January 2009 and December 2020. Patients were selected based on an Abbreviated Injury Scale (AIS) score ≥ 3 in the head region. Initial and follow-up SeMo ratios were calculated upon admission and 48-72 h later, respectively. The dynamic SeMo ratio was defined as the difference between the second and initial SeMo ratios. Statistical analyses included receiver operating characteristic (ROC) curve analysis to determine the optimal threshold for mortality prediction, and comparative analysis of clinical outcomes. The study cohort included 121 deceased and 997 surviving patients. Deceased patients had significantly higher second SeMo ratios (20.9 ± 16.1 vs. 15.8 ± 17.2, p = 0.001) and dynamic SeMo ratios (2.4 ± 19.8 vs. -2.1 ± 19.5, p = 0.019) than those survival patients. In the multivariate analysis, the dynamic SeMo is a significant independent risk factor for in-hospital mortality (OR 1.01, 95%CI: 1.01-1.03, p = 0.031). The optimal cut-off for the dynamic SeMo ratio was 5.96, above which patients exhibited higher mortality (21.4% vs. 8.5%, p < 0.001), higher adjusted mortality (adjusted odds ratio: 2.98; 95% confidence interval: 1.95-4.56; p = 0.005), and longer hospital stays (23.6 days vs. 19.7 days, p = 0.005). Dynamic SeMo ratio changes serve as a prognostic marker for in-hospital mortality and hospital stay duration in moderate to severe TBI patients. A higher dynamic SeMo ratio indicates increased risk, highlighting the importance of early monitoring and intervention. Future prospective studies should validate these findings and explore integration with other biomarkers for enhanced prognostication.

Prognostic Nomogram for Predicting Survival, Clinicopathological Analysis, and Racial Disparities in Uterine Carcinosarcoma: A Retrospective Population-Based Study

Introduction: Uterine carcinosarcoma is an aggressive gynecologic malignancy that accounts for 5% of all gynecological malignancies. There is a disproportion in its incidence and mortality among different races. This study describes demographic and clinicopathological factors and racial disparities affecting the survival of patients with uterine carcinosarcoma. Methods: Data on uterine carcinosarcoma patients were obtained from the Surveillance, Epidemiology, and End Results (SEER) database from 2000 to 2020. Results: Of the 11,338 patients identified, the median age at diagnosis was 68 years, and the five-year cause-specific survival (CSS) rate was 38.7%. for all races. Compared with Asian patients (39.5%, 95% CI, 36.0–43.4%), Hispanic patients (39.4%, 95% CI, 36.5–42.5%), and White patients (37.9%, 95% CI, 36.7–39.2%), Black patients accounted for 21% of the patients and had a significantly lower 5-year CSS (95% CI, 27.2–31.2%). The CSS rates were 84.4% (95% CI, 83.3–85.6%) for localized tumors, 68.5% (95% CI, 66.9–70.1%) for regional tumors, and 39.0% (95% CI, 36.9–41.2%) for distant tumors. Multimodal treatment involving chemotherapy, surgery, and radiation improved the overall one- and five-year survival rates by 88.2% (95% CI, 87.0–89.5%) and 52.8% (95% CI, 50.7–55.1%), respectively, across all disease stages. Multivariate analysis identified age &gt;60 years, Black race, tumor size &gt;4 cm, and distant metastases as independent risk factors for mortality (p &lt; 0.0001). Conclusions: This large database study presents the most up-to-date epidemiological information regarding cases of uterine carcinosarcoma. The findings suggest that a combination of surgery, chemotherapy, and radiation may be most efficacious in treating this malignancy, especially in patients with distant disease.

Role of Intraoperative Left Ventricular Global Longitudinal Strain in Hemodynamic and Cognitive Outcomes in On-Pump Coronary Artery Bypass Surgery: A Prospective Observational Study

ABSTRACT Background: The role of left ventricular global longitudinal strain (LVGLS) in coronary artery bypass grafting (CABG) and outcomes such as low cardiac output syndrome (LCOS) is not well established. The authors investigated the relationship between LVGLS before and after induction of anesthesia, their differences, and their relationship with LCOS and other outcomes. Methodology: A prospective observational study was conducted in a public/private hospital with 50 adult patients scheduled for on-pump CABG with normal left ventricular ejection fraction (LVEF). Acoustic windows necessary to obtain the 2D-LVGLS were acquired with transthoracic echocardiography (TTE) before induction of anesthesia (LVGLSBI) and after with mechanical ventilation (LVGLSAI) using transesophageal echocardiography (TEE). LCOS was defined as the use of epinephrine, dobutamine, and/or milrinone at minimum IV doses of 1 μg/min-1, 2.5 μg/kg-1/min-1, and 0.375 μg/kg-1/min-1, respectively, for a minimum of 24 h after cardiopulmonary bypass. Results: A dedicated workstation (EchoPAC Software v203, GE) was used for offline calculation of LVGLS. LVGLSBI did not have a significant correlation with LCOS (mean difference, 1.66; 95% CI, −–3.63 to 3.05; P = 0.862), nevertheless, it was an independent risk factor of in-hospital mortality (OR, 0.74; 95% CI, 0.57–0.95; P = 0.02), 3-month mortality (OR, 0.80; 95% CI, 0.64–0.99; P = 0.05), and delirium (OR, 0.65; 95% CI, 0.43–0.97; P = 0.03) in the multivariate analysis. LVGLSAI was also an independent risk factor for 3-month mortality (OR, 0.78; 95% CI, 0.62–0.99; P = 0.04). Conclusions: In CABG surgeries, LVGLS was a predictor of adverse outcomes in both awake and anesthetized patients with normal LVEF.

Risk and impact of cytomegalovirus infection in lymphoma patients treated with bendamustine.

Bendamustine is used to treat lymphoma with excellent efficacy but is known for its immunosuppressive effect. Cytomegalovirus (CMV) reactivation after bendamustine use has been reported. We aim to address the impact of CMV infection in lymphoma patients treated with bendamustine-containing regimens. We retrospectively analyzed lymphoma patients at Taipei Veterans General Hospital in Taiwan between September 1, 2010, and April 30, 2022. Clinically significant CMV infection (CS-CMVi) was defined as the first CMV reactivation after bendamustine use necessitating CMV therapy. Patients' baseline characteristics and laboratory data were recorded. The primary endpoint of the study was CS-CMVi. A time-dependent covariate Cox regression model was used to estimate the risk factors of CS-CMVi and mortality. A total of 211 lymphoma patients treated with bendamustine were enrolled. Twenty-seven (12.8%) had CS-CMVi. The cumulative incidence was 10.1 per 100 person-years during the three-year follow-up period. In the multivariate analysis, lines of therapy before bendamustine≥ 1 (95% CI 1.10-24.76), serum albumin < 3.5g/dL (95% CI 2.63-52.93), and liver disease (95% CI 1.51-28.61) were risk factors for CS-CMVi. In conclusion,CS-CMVi (95% confidence interval [CI] 1.23-10.73) was one of the major independent risk factors of mortality. Lines of therapy before bendamustine≥ 1, hypoalbuminemia, and liver disease were risk factors for CS-CMVi in lymphoma patients treated with bendamustine.

Distribution characteristics of human herpes viruses in the lower respiratory tract and their impact on 30-day mortality in community-acquired pneumonia patients.

Human herpes viruses (HHVs) are commonly detected in community-acquired pneumonia (CAP) patients, particularly those with complex complications, attracting increased attention from clinical practitioners. However, the significance of detecting HHVs in bronchoalveolar lavage fluid (BALF) with CAP patients is still unclear. This study retrospectively analyzed BALF samples from 64 CAP patients at the Kunming Third People's Hospital between August 2021 and December 2023. Metagenomic next generation sequencing (mNGS) was conducted on BALF samples during CAP onset. Multivariate Cox regression models were used to identify independent risk factors for 30-day all-cause mortality in CAP. HHVs were found in 84.4% of CAP patients, which were the most common pathogens (45.1%), followed by bacteria (30.2%) and fungi (11.5%). Bacterial-viral co-infections were most common, occurring in 39 patients. Notably, there was no significant difference in HHV presence between severe and non-severe CAP patients (EBV: P = 0.431, CMV: P = 0.825), except for HHV-7 (P = 0.025). In addition, there was no significant difference in the 30-day mortality between HHV positive and HHV negative groups (P = 0.470), as well as between the HHV-7 positive and HHV-7 negative groups (P = 0.910). However, neither HHVs nor HHV-7 was independent risk factors for 30-day mortality in CAP patients (HHVs: HR 1.171, P = 0.888; HHV-7: HR 1.947, P = 0.382). In summary, among the prevalent presence of multiple HHVs, EBV and CMV were the most prevalent in CAP patients. Patients with sCAP were more susceptible to HHV-7 than those with non-sCAP. These results provide valuable insights for clinicians in guiding appropriate interventions for CAP treatment.

The Clinical Characteristics and Outcomes of Acute Pancreatitis Are Different in Elderly Patients: A Single-Center Study over a 6-Year Period.

Objectives: This study aims to analyze the clinical characteristics of elderly patients with acute pancreatitis (AP) and investigate the effects of age on the clinical outcomes of AP. Methods: Patients aged ≥ 18 years with AP admitted within 72 h from 1 September 2013 to 31 August 2019 were included. Patients were divided into elderly (≥60 years) and non-elderly (<60 years) groups. Clinical data and outcomes were compared. Results: A total of 756 elderly and 4896 non-elderly patients with AP were included. The elderly patients had different etiological distributions and more severe clinical markers and scores. Age was an independent risk factor for mortality [odds ratio (OR): 2.911, 95% CI: 1.801-4.706, p < 0.001], intensive care unit admission (OR: 1.739, 95% CI: 1.126-2.685, p = 0.013), persistent organ failure (OR: 1.623, 95% CI: 1.326-1.987, p < 0.001), multiple organ failure (OR: 1.757, 95% CI: 1.186-2.604, p = 0.005), and infection (OR: 2.451, 95% CI: 1.994-3.013, p < 0.001). Adjusted multiple logistic regression and trend analysis confirmed the risk of the age for the outcomes. The deaths of elderly patients showed a biphasic pattern with peaks in the first and fifth weeks, in contrast to the single peak in the first week in the non-elderly patients. Conclusions: Elderly patients with AP were associated with worse clinical outcomes. It is crucial to devote considerable attention to the optimization of therapeutic approaches to reduce late mortality in this group of patients.

Prolonged Inotrope Use After Surgery for Congenital Heart Disease: A Common Occurrence with a High Burden of Mortality.

Outcomes in patients requiring prolonged inotropes (PI) following surgery for congenital heart disease (CHD) have not been well studied. We aimed to describe the burden of PI use in the immediate postoperative period after CHD surgery and identify risk factors for in-hospital mortality. We conducted a retrospective cohort study using the Pediatric Health Information System® (PHIS) database. Patients 0-18years with CHD who underwent cardiovascular surgery from 2010 to 2020 were included. Patients who received inotropic medications for > 7 consecutive days after surgery were in the PI group and all others in the control group. Patients who died before 7days were excluded. Multivariable mixed-effect logistic regression was used to examine risk factors for in-hospital mortality. There were 110,271 patients from 48 centers included, 10,292 in the PI group and 99,979 in the control group. In-hospital mortality was significantly higher in the PI group (24.9% vs. 4.6%, p < 0.001). Ventricular assist device use was rare (1.6%). After adjustment, odds of in-hospital mortality in the PI group was 3.5 (95% CI 3.3-3.8) times higher than in controls. Independent risk factors for in-hospital mortality were age, non-White race, class of CHD, number of complex chronic conditions, preoperative inotrope, preoperative extracorporeal membrane oxygenation, sepsis, stroke, renal failure, number of inotropes at 7days, and discharge year (p < 0.01 for all). Postoperative PI use in CHD is common and carries a considerable burden of mortality. Additional work is needed to understand which risk factors are modifiable and which patients may benefit from reintervention or advanced heart failure therapies.
