BACKGROUND: Heart failure is a disease that threatens global public safety. In recent years, the obesity paradox has been studied in cardiovascular disease and other fields. With the progress of aging, metabolic changes and regulation of fat function, it also provides many bridges for the dialogue between disease and molecular metabolism. The purpose of this study is to investigate the effect of obesity on the outcome of adult intensive care patients with heart failure combined with age factors.
METHODS: Data were derived from the fourth-generation Medical Information Marketplace for Intensive Care (MIMIC-IV version2.1) using structured query language on the Navicat (12.0.11) platform. People were divided into two groups based on the body mass index (BMI), one group with BMI ≥ 30 kg/m² and another group with BMI < 30 kg/m². Afterwards, the patients were divided into two subgroups based on their ages. One group included patients aged<60, and the other included patients aged ≥ 60. The extracted information includes demographic characteristics, laboratory findings, comorbidities, scores. Main results included in-hospital mortality, ICU mortality, and 1-year mortality. Secondary outcomes included hospital interval and ICU interval, use of renal replacement therapy, and rates of noninvasive and invasive ventilation support.
RESULTS: In this cohort study, 3390 people were in the BMI<30 group, 2301 people were in the BMI ≥ 30 group, 960 people were in the age<60 group, and 4731 people were in the age ≥ 60 group, including 3557 patients after propensity score matching in high age group. Among patients aged ≥ 60, BMI ≥ 30 group vs. BMI<30 group showed significantly lower in-hospital mortality (13% vs. 16%) and one-year mortality (41% vs. 55%), respectively. Neither primary nor secondary outcomes were significantly described in the competition among patients aged under 60. Restricted cubic spline reveals a J-shaped nonlinear association between BMI and clinical endpoints within the entire cohort. Kaplan-Meier curves revealed a survival advantage in BMI ≥ 30 group (p < 0.001). Following age stratification, a beneficial effect of BMI categories on one-year mortality risk was observed in heart failure patients aged ≥ 60 (Univariable HR, 0.71, 95% CI, 0.65-0.78, p < 0.001; Multivariable HR, 0.74, 95% CI, 0.67-0.81, p < 0.001), but not in those under 60 years old.
RESULTS: In ICU patients with heart failure, obesity offers a survival benefit to those aged ≥ 60. No obesity paradox was observed in patients younger than 60 years old. The obesity paradox applies to patients aged ≥ 60 with heart failure.

Patients with locally advanced head and neck squamous cell carcinoma (LA-HNSCC) have poor survival outcomes. The real-world efficacy of nimotuzumab plus intensity modulated radiotherapy (IMRT)-based chemoradiotherapy in patients with LA-HNSCC remains unclear. A total of 25,442 HNSCC patients were screened, and 612 patients were matched by propensity score matching (PSM) (1:1). PSM was utilized to balance known confounding factors. Patients who completed at least five doses of nimotuzumab were identified as study group. The primary end point was 3-year overall survival (OS) rate. Log-rank test examined the difference between two survival curves and Cloglog transformation test was performed to compare survival at a fixed time point. The median follow-up time was 54.2 (95% confidence interval [CI]: 52.7-55.9) months. The study group was associated with improved OS (hazard ratio [HR] = 0.75, 95% CI: 0.57-0.99, p = 0.038) and progression-free survival (PFS) (HR = 0.74, 95% CI: 0.58-0.96, p = 0.021). Subgroup analysis revealed that aged 50-60 year, IV, N2, radiotherapy dose ≥ 60 Gy, without previous surgery, and neoadjuvant therapy have a trend of survival benefit with nimotuzumab. Nimotuzumab showed favorable safety, only 0.2% had nimotuzumab-related severe adverse events. Our study indicated the nimotuzumab plus chemoradiotherapy provides survival benefits and safety for LA-HNSCC patients in an IMRT era.

UNASSIGNED: This study determined hazard factors and long-term survival rate of total arterial coronary artery bypass graft surgery over 20 years in an extensively large, population-based cohort.
UNASSIGNED: A total of 2979 patients who underwent isolated CABG from April 1999 to March 2020 were studied in 4 groups- Group-A (bilateral internal mammary artery ± radial artery), Group-B (single internal mammary artery + radial artery ± saphenous vein), Group-C (single internal mammary artery ± saphenous vein; no radial artery), and Group-D (radial artery ± saphenous vein; no internal mammary artery). The study endpoints analysed the correlation between the number and types of grafts with the survival time following isolated CABG surgery.
UNASSIGNED: The total arterial revascularization (Group A) group had an admirable mean long-term survival of ~19 years, compared to 18.6 years (Group B), 15.86 years (Group C), and 10.99 years (Group D). A Kaplan-Meier curve demonstrated confidence interval (CI) for study groups- (95% CI 18.33-19.94), (95% CI 18.14-19.06), (95% CI 15.40-16.32), and (95% CI 9.61-12.38) in Group A, B, C, D respectively. In the Holm-Sidak method analysis, significant associations existed between the number of arterial grafts and the long-term outcome. A statistically significant (P≤0.05) long-term survival advantage for arterial grafting was demonstrated, especially total arterial revascularisation over all other combinations except single internal mammary artery + radial artery grafting.
UNASSIGNED: In this series, over 20 years, total arterial CABG use has excellent long-term survival, achieving complete myocardial revascularisation. There is no significant difference between the BIMA group and SIMA with radial artery. However, there is a reduced survival with decreased use of arterial conduits.

UNASSIGNED: There is an ongoing debate regarding the comparative merits of splenectomy (SP) and splenic preservation in the surgical management of gastric cancer. This systematic review and meta-analysis aims to shed light on potential differences in survival outcomes and postoperative complications associated with these two procedures.
UNASSIGNED: An exhaustive literature search was conducted across multiple databases, namely PubMed, Embase, Cochrane Library, and Web of Science. We utilized a random-effects model via RevMan 5.4 software to conduct a meta-analysis of the hazard ratios (HRs) and risk ratios (RRs) associated with SP and spleen preservation. Subgroup analyses were based on various attributes of the included studies. We employed funnel plots to assess publication bias, and sensitivity analysis was conducted to gauge the stability of the combined results. Both funnel plots and sensitivity analysis were performed using Stata 12.
UNASSIGNED: Our research incorporated 23 observational studies and three randomized controlled trials, involving a total of 6,255 patients. SP did not yield superior survival outcomes in comparison to splenic preservation, a conclusion that aligns with the combined results of the randomized controlled trials. No statistically significant difference in survival prognosis was observed between SP and splenic preservation, irrespective of whether the patients had proximal gastric cancer or proximal gastric cancer invading the stomach\'s greater curvature. SP exhibited a higher incidence of all postoperative complications, notably pancreatic fistula and intraabdominal abscesses. However, it did not significantly differ from splenic preservation in terms of anastomotic leakage, incision infection, intestinal obstruction, intra-abdominal bleeding, and pulmonary infection. No significant difference in postoperative mortality between SP and splenic preservation was found. Funnel plots suggested no notable publication bias, and sensitivity analysis affirmed the stability of the combined outcomes.
UNASSIGNED: Despite the lack of significant differences in certain individual complications and postoperative mortality, the broader pattern of our data suggests that SP is associated with a greater overall frequency of postoperative complications, without providing additional survival benefits compared to splenic preservation. Thus, the routine implementation of SP is not advocated.
When doctors perform surgery for gastric (stomach) cancer, they sometimes remove the spleen, a procedure known as splenectomy (SP). However, there’s a debate on whether removing the spleen is better than preserving it. Our study aimed to compare these two methods in terms of patient survival and the risk of complications after surgery. To do this, we looked at data from 26 studies involving 6,255 patients. Our analysis was thorough, using advanced statistical methods to ensure accuracy. Here’s what we found: patients who had their spleen removed did not live longer than those who kept their spleen. Whether the cancer was just in the upper part of the stomach or had spread to the nearby large curve of the stomach, the survival rates were similar for both groups. Patients who underwent SP faced more postoperative complications, especially issues like pancreatic fistula and intra-abdominal abscesses. However, for some complications like leakage from the surgical joint, infection of the wound, bowel obstruction, internal bleeding, and lung infections, there was no significant difference between the two groups. The chances of dying post-surgery were similar whether patients had their spleen removed or not. Our findings suggest that routinely removing the spleen during gastric cancer surgery does not improve survival rates and is linked to more postoperative complications. Therefore, it may be better to avoid removing the spleen unless absolutely necessary.

Oligometastatic prostate cancer is a term that is most often used to refer to limited sites of disseminated tumor growth following primary radical prostatectomy (RP) or radiotherapy (RT), while de novo oligometastatic is a term that is used to refer to prostate tumors that have disseminated to limited sites before definitive treatment. In patients with de novo oligometastatic prostate cancer, treatment planning must thus consider the need to manage the primary tumor and the associated distant lesions. Traditionally, resectioning primary metastatic tumors is not thought to offer significant benefits to affected patients while increasing their risk of surgery-related complications. Recent clinical evidence indicates that patients undergoing cytoreductive prostatectomy (CRP) may observe substantial enhancements in overall survival rates while not experiencing a noticeable decline in their quality of life. Nevertheless, based on the current body of evidence, it is deemed inadequate to justify revising clinical guidelines. Consequently, it is not advisable to propose CRP for patients with oligometastatic prostate cancer. The present review was compiled to summarize available data regarding the indications, functional outcomes, and oncological outcomes associated with cytoreductive radical prostatectomy to provide a robust and objective foundation that can be used to better assess the value of this interventional strategy from a clinical perspective.

BACKGROUND: The established association between the inflammatory marker, neutrophil-lymphocyte ratio (NLR), and both long-term surgical prognosis and short-term postoperative complications is well-recognized. However, its prognostic value in pancreaticoduodenectomy (PD) is yet to be ascertained. This meta-analysis investigates the prognostic relevance of preoperative NLR in PD patients.
METHODS: We systematically searched electronic databases to identify studies exploring the relationship between pre-treatment blood NLR levels and overall survival (OS), disease-free survival (DFS), and immediate postoperative complications in PD patients. Statistical evaluations, using RevMan 5.4 and Stata 12, focused on hazard ratios (HRs) and risk ratios (RRs). Additionally, subgroup analyses, publication bias tests, and sensitivity analyses were performed.
RESULTS: Our analysis encompassed 18 retrospective studies, with NLR cutoff values ranging from 2 to 3.8. The meta-analysis revealed that PD patients with elevated NLR had diminished OS and DFS, evidenced by an HR of 1.35 (95% CI: 1.11-1.64, p ​= ​0.003) and 1.62 (95% CI: 1.15-2.27, p ​= ​0.005), respectively. Moreover, NLR emerged as an independent determinant of immediate postoperative complications, indicated by an OR of 1.91 (95% CI: 1.01-3.59, p ​= ​0.013) and an HR of 2.15 (95% CI: 1.23-3.73, p ​< ​0.01).
CONCLUSIONS: NLR serves as a significant prognostic indicator for both OS and DFS following PD and is a reliable predictor of postoperative complications. Preoperative Neutrophil-to-Lymphocyte Ratio (NLR) is a significant prognostic indicator for overall survival (OS) and disease-free survival (DFS) in patients undergoing pancreaticoduodenectomy (PD).

OBJECTIVE: To compare the long-term survival benefits of hepatocellular carcinoma (HCC) in thermal ablation (TA) monotherapy and TA combined with transarterial chemoembolization (TACE) using propensity score matching (PSM).
METHODS: Between 1 January 2015 and 28 February 2021, 432 consecutive patients (357 men, 75 women; age range, 20-87 years) with HCC (Barcelona Clinic Liver Cancer stage 0-B) underwent ultrasonography-guided percutaneous TA, which included radiofrequency ablation (n = 340) and microwave ablation (n = 92). The association between combined treatment of TACE prior to TA versus TA monotherapy and survival prognosis was evaluated, including (a) local tumor progression (LTP) by using a logistic regression model, and (b) disease-free survival (DFS) and (c) overall survival (OS) by using a Cox proportional hazards model according to propensity score matched data.
RESULTS: After PSM, the final matched cohort consisted of 146 patients, with 73 receiving TA monotherapy and 73 receiving TA combined with TACE. The cumulative LTP rates did not show a significant difference between the two groups (P = 0.960). Neither the DFS nor OS rate was significantly different between the two groups (P = 0.070 and P = 0.680, respectively). The multivariate analysis identified two significant findings. Firstly, ultrasound echo, minimal ablative margin, and high risk of tumor burden score were found to be associated with LTP. Secondly, the type of TA, Child-Turcotte-Pugh grade, ablation time, and lymphocyte-monocyte ratio were identified as independent prognostic factors for OS.
CONCLUSIONS: The differences in LTP, DFS, and OS rates of HCC patients were found to be statistically non-significant between TA monotherapy and TACE + TA groups. For HCC patients with BCLC stage 0-B, the combination treatment of TACE prior to TA may be not associated with long-term survival benefits relative to TA monotherapy.

BACKGROUND: Contralateral prophylactic mastectomy (CPM) has been performed for several decades in patients with unilateral breast cancer (BC). However, the survival benefits of CPM are controversial, particularly in young women.
METHODS: In this retrospective study, the clinical total of 69,000 young female patients (age ≤ 40 years) who were diagnosed to have unilateral BC and underwent unilateral mastectomy (UM) or CPM between January 1, 2000 and December 31, 2019 were retrieved from the Surveillance, Epidemiology, and End Results (SEER) database. Propensity score matching (PSM) was performed to minimize selection bias and overcome differences in tumor characteristics between the CPM and UM groups. Overall survival (OS) and BC-specific survival (BCSS) were assessed using Kaplan-Meier curves and compared across groups using log-rank test. Multivariable Cox proportional hazards regression analysis was performed to estimate hazard ratios (HRs).
RESULTS: A total of 36,528 patients (21,600 and 14,928 patients in the UM and CPM groups, respectively) were included in follow study. The CPM group showed a higher 5-year OS rate (82.1% vs. 75.8%) and a higher 5-year BCSS rate (83.5% vs. 77.7%) than the UM group. Multivariate Cox analysis after PSM (n = 13,089) showed that CPM significantly decreased 25% risk of all-cause mortality (OS, HR: 0.75, 95% confidence interval [CI]: 0.70-0.80; P < .001) and 25% risk of BC-specific mortality (BCSS, HR: 0.75, 95% CI: 0.70-0.80; P < .001) in young BC patients as compared to UM.
CONCLUSIONS: This study suggests that CPM improved OS and BCSS benefits in young BC patients as compared to UM. Randomized clinical trials with a larger sample size are required in the future to confirm these results.

UNASSIGNED: We aimed to investigate the predictive value of a systematic serum inflammation index, pan-immune-inflammatory value (PIV), in pathological complete response (pCR) of patients treated with neoadjuvant immunotherapy to further promote ideal patients\' selection.
UNASSIGNED: The clinicopathological and baseline laboratory information of 128 NSCLC patients receiving neoadjuvant immunochemotherapy between October 2019 and April 2022 were retrospectively reviewed. We performed least absolute shrinkage and selection operator (LASSO) algorithm to screen candidate serum biomarkers for predicting pCR, which further entered the multivariate logistic regression model to determine final biomarkers. Accordingly, a diagnostic model for predicting individual pCR was established. Kaplan-Meier method was utilized to estimate curves of disease-free survival (DFS), and the Log rank test was analyzed to compare DFS differences between patients with and without pCR.
UNASSIGNED: Patients with NSCLC heterogeneously responded to neoadjuvant immunotherapy, and those with pCR had a significant longer DFS than patients without pCR. Through LASSO and the multivariate logistic regression model, PIV was identified as a predictor for predicting pCR of patients. Subsequently, a diagnostic model integrating with PIV, differentiated degree and histological type was constructed to predict pCR, which presented a satisfactory predictive power (AUC, 0.736), significant agreement between actual and our nomogram-predicted pathological response.
UNASSIGNED: Baseline PIV was an independent predictor of pCR for NSCLC patients receiving neoadjuvant immunochemotherapy. A significantly longer DFS was achieved in patients with pCR rather than those without pCR; thus, the PIV-based diagnostic model might serve as a practical tool to identify ideal patients for neoadjuvant immunotherapeutic guidance.

BACKGROUND:  The types of graft conduits and surgical techniques may impact the long-term outcomes of patients after coronary artery bypass graft (CABG) revascularization. This study observed a long-term survival rate following CABG surgery over 20 years in the United Kingdom.
METHODS:  A total of 2979 isolated CABG patients were studied from 1999 to 2020, and postoperative data were obtained from the hospital-recorded mortality by the data quality team of the information department. Postdischarge survival was estimated using the Kaplan-Meier method, and statistical significance was obtained with log-rank tests and the Gehan-Breslow test, and the Holm-Sidak method was used for multiple pairwise comparisons.
RESULTS:  The study observed male predominance (80%), and the median age was statistically significant (P <0.001) among the groups, 66 years (interquartile range 58-73) and 72 years (interquartile range 66-78) in survivor and non-survivor groups, respectively. In the Holm-Sidak method analysis, the best survival rate (mean 18.7 years) was observed in the total arterial group with significantly decreased survival for the mixed arterial and venous group (mean 16.12 years) and only the vein group (10.44 years). The Cox regression model observed that the New York Heart Association (NYHA) class III-IV (HR 1.57), chest re-exploration (HR 2.14), preoperative dialysis (HR 3.13), and redo surgery (HR 3.04) were potential predictors of the postoperative mortality (P ≤0.05).
CONCLUSIONS:  In our series over 20 years, albeit off-pump and on-pump CABG observed similar survival rates, the total arterial myocardial revascularization population has significantly better long-term survival benefits.
