Body morphometry may predict parastomal hernia following radical cystectomy with ileal conduit.

To investigate whether preoperative body morphometry analysis can identify patients at risk of parastomal hernia (PH), which is a common complication after radical cystectomy (RC). All patients who underwent RC between 2010 and 2020 with available cross-sectional imaging preoperatively and at 1 and 2 years postoperatively were included. Skeletal muscle mass and total fat mass (FM) were determined from preoperative axial computed tomography images obtained at the level of the L3 vertebral body using Aquarius Intuition software. Sarcopenia and obesity were assigned based on consensus definitions of skeletal muscle index (SMI) and FM index (FMI). PH were graded using both the Moreno-Matias and European Hernia Society criteria. Binary logistic regression and recursive partitioning were used to identify patients at risk of PH. The Kaplan-Meier method with log-rank and Cox proportional hazards models included clinical and image-based parameters to identify predictors of PH-free survival. A total of 367 patients were included in the final analysis, with 159 (43%) developing a PH. When utilising binary logistic regression, high FMI (odds ratio [OR] 1.63, P < 0.001) and low SMI (OR 0.96, P = 0.039) were primary drivers of risk of PH. A simplified model that only relied upon FMI, SMI, and preoperative albumin improved the classification of patients at risk of PH. On Kaplan-Meier analysis, patients who were obese or obese and sarcopenic had significantly worse PH-free survival (P < 0.001). Body morphometry analysis identified FMI and SMI to be the most consistent predictors of PH after RC.

Efficacy and safety of percutaneous transhepatic biliary radiofrequency ablation in patients with malignant obstructive jaundice.

Percutaneous transhepatic cholangiodrainage (PTCD) and endoscopic retrograde cholangiopancreatography/endoscopic nasobiliary drainage are the most common clinical procedures for jaundice control in patients with unresectable malignant obstructive jaundice, yet the safety and effect of endobiliary radiofrequency ablation (EB-RFA) combined PTCD is rarely reported, in this article, we report our experience of EB-RFA combined PTCD in such patients. To retrospectively study the efficacy and safety of EB-RFA combined PTCD in patients with unresectable malignant obstructive jaundice. Patients with unresectable malignant obstructive jaundice treated with EB-RFA under PTCD were selected, the bile ducts of the right posterior lobe was selected as the target bile ducts in all cases. The general conditions of all patients, preoperative tumour markers, total bilirubin (TBIL), direct bilirubin (DBIL), albumin (ALB), alkaline phosphatase (ALP), and glutamyl transferase (GGT) before and on the 7th day after the procedure, as well as perioperative complications, stent patency time and patient survival were recorded. All patients successfully completed the operation, TBIL and DBIL decreased significantly in all patients at the 7th postoperative day (P = 0.009 and 0.006, respectively); the values of ALB, ALP and GGT also decreased compared with the preoperative period, but the difference was not statistically significant. Perioperative biliary bleeding occurred in 2 patients, which was improved after transfusion of blood and other conservative treatments, pancreatitis appeared in 1 patient after the operation, no serious complication and death happened after operation. Except for 3 patients with loss of visits, the stent patency rate of the remaining 14 patients was 100% 71% and 29% at the 1st, 3rd, and 6th postoperative months respectively, with a median survival of 4 months. EB-RFA under PTCD in patients with unresectable malignant obstructive jaundice has a satisfactory therapeutic effect and high safety, which is worthy of further clinical practice.

Frailty Increases Morbidity and Mortality in Patients Undergoing Oncological Liver Resections: A Systematic Review and Meta-analysis

BackgroundConsidered to reflect a patients’ biological age, frailty is a new syndrome shown to predict surgical outcomes in elderly patients. In view of the increasing age at which patients are proposed oncological liver surgery and the morbidity associated with it, we attempted to perform a systematic review and meta-analysis to compare morbidity and mortality between frail and nonfrail patients after liver resections.MethodsThe study was registered with PROSPERO. A systematic search of PubMed and EMBASE databases was performed for all comparative studies examining surgical outcomes after liver resections between frail and nonfrail patients.ResultsTen studies were included based on the selection criteria with a total of 71,102 patients, split into two groups: frail (n = 17,167) and the control group (n = 53,928). There were more elderly patients with a lower preoperative albumin level in the frail group (p = 0.02, p = 0.001). Frail patients showed higher rates of morbidity with more major complications and a higher incidence of postoperative liver failure (p < 0.001). Mortality (p < 0.001) and readmission rate (p = 0.021) also was higher in frail patients.ConclusionsFrailty seems to be a solid predictive risk factor of morbidity and mortality after liver surgery and should be considered a selection criterion for liver surgery in at-risk patients.

Association between preoperative albumin and length of hospital stay in non-cardiac surgery patients with pulmonary hypertension: A secondary retrospective analysis.

To explore the risk factors affecting the length of hospital stay (LOS) as well as to examine the relationship between preoperative serum albumin levels and LOS following non-cardiac, non-obstetric surgery in patients with pulmonary hypertension (PHTN). This study represents a secondary retrospective analysis based on 287 non-cardiac, non-obstetric procedures performed on 195 PTHN patients at a single institution in the USA between 2007 and 2013. The primary outcome was the LOS. We conducted a multiple logistic regression analysis to compare the LOS between the 2 groups, divided at a serum albumin level of 3.5 g/dL. After adjusting for multiple covariates, the ORs for the long length of stay (LOS > 7 days) for the high group(albumin > 3.5 g/dL) compared with the low group (albumin ≤ 3.5 g/dL) were 0.35 (95%CI: 0.21~0.6), 0.41 (95%CI: 0.22 ~0.76), 0.41 (95%CI: 0.18~0.94) from model 2 to model 4. The stratified analysis results indicate that these findings are stable (p for trend > 0.05). In this study, it was observed that low levels of preoperative albumin were associated with an increased risk of prolonged hospital stay after non-cardiac, non-obstetric surgery in patients with PHTN. This implies that optimizing preoperative nutrition could potentially reduce the LOS for non-cardiac, non-obstetric surgery in patients with PHTN.

Postoperative Crohn's Disease Recurrence Risk and Optimal Biologic Timing After Temporary Diversion Following Ileocolic Resection.

Postoperative recurrence of Crohn's disease (CD) is common. While most patients undergo resection with undiverted anastomosis (UA), some individuals also have creation of an intended temporary diversion (ITD) with an ileostomy followed by ostomy takedown (OT) due to increased risk of anastomotic complications. We assessed the association of diversion with subsequent CD recurrence risk and the influence of biologic prophylaxis timing to prevent recurrence in this population. This was a retrospective cohort study of CD patients who underwent ileocolic resection between 2009 and 2020 at a large quaternary health system. Patients were grouped by continuity status after index resection (primary anastomosis or ITD). The outcomes of the study were radiographic, endoscopic, and surgical recurrence as well as composite recurrence postoperatively (after OT in the ITD group). Propensity score-weighted matching was performed based on risk factors for diversion and recurrence. Multivariable regression and a Cox proportional hazards model adjusting for recurrence risk factors were used to assess association with outcomes. Subgroup analysis in the ITD group was performed to assess the impact of biologic timing relative to OT (no biologic, biologic before OT, after OT) on composite recurrence. A total of 793 CD patients were included (mean age 38 years, body mass index 23.7kg/m2, 52% female, 23% active smoker, 50% penetrating disease). Primary anastomosiswas performed in 67.5% (n = 535) and ITD in 32.5% (n = 258; 79% loop, 21% end) of patients. Diverted patients were more likely to have been males and to have had penetrating and perianal disease, prior biologic use, lower body mass index, and lower preoperative hemoglobin and albumin (all P < .01). After a median follow-up of 44 months, postoperative recurrence was identified in 83.3% patients (radiographic 40.4%, endoscopic 39.5%, surgical 13.3%). After propensity score matching and adjusting for recurrence risk factors, no significant differences were seen between continuity groups in radiographic (adjusted hazard ratio [aHR], 1.32; 95% confidence interval [CI], 0.91-1.91) or endoscopic recurrence (aHR, 1.196; 95% CI, 0.84-1.73), but an increased risk of surgical recurrence was noted in the ITD group (aHR, 1.61; 95% CI, 1.02-2.54). Most (56.1%) ITD patients started biologic prophylaxis after OT, 11.4% before OT, and 32.4% had no postoperative biologic prophylaxis. Biologic prophylaxis in ITD was associated with younger age (P < .001), perianal disease (P = .04), and prior biologic use (P < .001) but not in recurrence (P = .12). Despite higher rates of objective disease activity identified before OT, biologic exposure before OT was not associated with a significant reduction in composite post-OT recurrence compared with starting a biologic after OT (52% vs 70.7%; P = 0.09). Diversion of an ileocolic resection is not consistently associated with a risk of postoperative recurrence and should be performed when clinically appropriate. Patients requiring diversion at time of ileocolic resection are at high risk for recurrence, and biologic initiation prior to stoma reversal may be considered.

Development of machine learning models to predict perioperative blood transfusion in hip surgery

BackgroundAllogeneic Blood transfusion is common in hip surgery but is associated with increased morbidity. Accurate prediction of transfusion risk is necessary for minimizing blood product waste and preoperative decision-making. The study aimed to develop machine learning models for predicting perioperative blood transfusion in hip surgery and identify significant risk factors.MethodsData of patients undergoing hip surgery between January 2013 and October 2021 in the Peking Union Medical College Hospital were collected to train and test predictive models. The primary outcome was perioperative red blood cell (RBC) transfusion within 72 h of surgery. Fourteen machine learning algorithms were established to predict blood transfusion risk incorporating patient demographic characteristics, preoperative laboratory tests, and surgical information. Discrimination, calibration, and decision curve analysis were used to evaluate machine learning models. SHapley Additive exPlanations (SHAP) was performed to interpret models.ResultsIn this study, 2431 hip surgeries were included. The Ridge Classifier performed the best with an AUC = 0.85 (95% CI, 0.81 to 0.88) and a Brier score = 0.21. Patient-related risk factors included lower preoperative hemoglobin, American Society of Anesthesiologists (ASA) Physical Status > 2, anemia, lower preoperative fibrinogen, and lower preoperative albumin. Surgery-related risk factors included longer operation time, total hip arthroplasty, and autotransfusion.ConclusionsThe machine learning model developed in this study achieved high predictive performance using available variables for perioperative blood transfusion in hip surgery. The predictors identified could be helpful for risk stratification, preoperative optimization, and outcomes improvement.

Significance of Adjuvant Chemotherapy for Obstructive Colorectal Cancer After Stent Placement: A Multicenter Retrospective Study.

To explore the survival benefit of adjuvant chemotherapy for obstructive colorectal cancer (OCRC) managed by self-expandable metallic stent (SEMS) placement as a bridge to surgery (BTS). One hundred twenty-nine patients with pathological stage II/III OCRC who underwent BTS using a SEMS were included in this multicenter retrospective study. Patients were divided into the no-adjuvant chemotherapy group (No-Adj group) (n=52) and adjuvant chemotherapy group (Adj group) (n=77), and relapse-free survival (RFS) was compared. The No-Adj group had more fragile patient background factors, such as higher age, higher American Society of Anesthesiologists score, and lower preoperative albumin compared with the Adj group. The 3-year RFS rates for the overall cohort were significantly different between the No-Adj and Adj groups (56.4% and 78.5%, respectively; p=0.003). Significant RFS benefits of adjuvant chemotherapy were observed in both pathological stage II and III cancer. Characteristics of more advanced cancer, such as high carcinoembryonic antigen (CEA), pathological T4, and lymphovascular invasion, were associated with survival improvement by adjuvant chemotherapy. T4 and adjuvant chemotherapy were significantly associated with RFS in the multivariate Cox proportional analysis. To our knowledge, this is the first study to show a survival benefit of adjuvant chemotherapy in patients with OCRC undergoing BTS using a SEMS. Adjuvant chemotherapy is basically recommended regardless of the cancer stage and is strongly recommended with more advanced characteristics, such as high CEA, T4, and lymphovascular invasion.

Incidence and associated factors of delirium after primary total joint arthroplasty in elderly patients: A systematic review and meta-analysis.

A total of 1.5% to 20.2% of total joint arthroplasty patients experience delirium. Until now, no formal systematic review or meta-analysis was performed to summarize the risk factors of delirium after primary total joint arthroplasty (TJA). A comprehensive search encompassing Medline, Embase, and the Cochrane central database was conducted, incorporating studies available up to June 2023. We systematically reviewed research on the risk factors contributing to delirium following TJA in elderly patients, without language restrictions. The methodological quality of the included studies was evaluated using the Newcastle-Ottawa Scale. Data synthesis through pooling and a meta-analysis were performed to analyze the findings. A total of 23 studies altogether included 71,095 patients with primary TJA, 2142 cases of delirium occurred after surgery, suggesting the accumulated incidence of 3.0%. The results indicated that age, current smoker, heavy drinker, mini-mental state examination score, hypertension, diabetes mellitus, chronic kidney disease, history of stroke, coronary arterial disease, dementia, history of psychiatric illness, American Society of Anesthesiologists physical status III-IV, general anesthesia, anesthesia time, operative time, intraoperative blood loss, blood transfusion, β-blockers, ACEI drugs, use of psychotropic drugs, preoperative C-reactive protein level, and preoperative albumin level were significantly associated with postoperative delirium after primary TJA. Related prophylaxis strategies should be implemented in the elderly involved with above-mentioned risk factors to prevent delirium after primary TJA.

Predictors of complications after prophylactic ileostomy reversal for rectal cancer: A retrospective study.

Previous studies have analyzed the risk factors for complications after ileostomy reversal for rectal cancer (RC), but there were significant differences in the reported risk factors for complications after stoma reversal. No studies have analyzed the risk factors for stoma-related complications and overall postoperative complications separately. To analyze the risk factors for overall complications and stoma-related complications after ileostomy reversal for patients with RC. This was a retrospective study of 439 patients who underwent ileostomy reversal at a clinical center and were followed up between September 2012 and September 2022. Continuous variables are expressed as the mean ± SD and were analyzed with independent-sample t tests, while frequency variables are expressed as n (%), and the χ2 test or Fisher's exact test was used. Univariate and multivariate logistic regression analyses were used to identify predictors of overall complications and stoma-related complications. The overall complication rate after ileostomy reversal was 11.4%. Patients with lower preoperative albumin concentration (P < 0.01), greater blood loss (P = 0.017), and longer operative times (P < 0.01) were more likely to experience postoperative complications. The incidence of stoma-related complications was 6.4%. Analysis of the study showed that a higher body mass index (BMI) (P < 0.01), preoperative comorbid hypertension (P = 0.049), time from primary surgery to ileostomy reversal (P < 0.01) and longer operation time (P = 0.010) were more likely to result in stoma-related complications postoperatively. Multivariate logistic regression analysis revealed that a lower preoperative albumin level (P < 0.01, OR = 0.888, 95%CI: 0.828-0.958) was an independent risk factor for overall complications. Moreover, multivariate analysis revealed that BMI (P < 0.01, OR = 1.176, 95%CI: 1.041-1.330) and time from primary surgery to ileostomy reversal (P < 0.01, OR = 1.140, 95%CI: 1.038-1.252) were independent risk factors for stoma-related complications after stoma reversal. The preoperative albumin level was a predictor of overall complications. Preoperative BMI and the time from primary surgery to ileostomy reversal were predictors of stoma-related complications.

The relationship between perioperative serum albumin and contrast-induced acute kidney injury in patients after percutaneous coronary intervention

ObjectiveContrast-induced acute kidney injury (CI-AKI) is a common complication in patients undergoing percutaneous coronary intervention (PCI). Studies have shown that perioperative serum albumin levels may play a role in the occurrence of CI-AKI. In this study, we aimed to investigate the effect of perioperative serum albumin (delta albumin or &Alb) levels on the occurrence and long-term prognosis of CI-AKI patients after PCI.MethodsA total of 959 patients who underwent PCI between January 2017 and January 2019 were selected for this study. A receiver operating characteristic curve was used to determine the optimal cut-off value of the &Alb level for predicting CI-AKI after PCI. Patients were divided into two groups based on the optimal cut-off value: the high &Alb group (&Alb ≥ 4.55 g/L) and the control group (&Alb < 4.55 g/L). The incidences of CI-AKI and major adverse cardiac events (MACEs, including all-cause death, nonfatal myocardial infarction, and target vessel revascularization) were compared between the groups. Cox regression analysis was used to identify predictors of long-term prognosis after PCI.ResultsOf the 959 patients, 147 (15.3%) developed CI-AKI after PCI. The CI-AKI group had a greater level of &Alb than did the non-CI-AKI group [(6.14 (3.90–9.10) versus 3.48 (4.31–6.57), P < 0.01)]. The incidence of CI-AKI in the high &Alb group was significantly greater than that in the low group (23.6% versus 8.3%, P < 0.01). After a 1-year follow-up, the incidence of MACEs was significantly greater in the high &Alb group than in the low group (18.6% versus 14.5%, P = 0.030). Cox regression analysis confirmed that CI-AKI was an independent predictor of MACEs at the 1-year follow-up (HR 1.43, 95% CI 1.04–1.96, P = 0.028). In addition, patients with low preoperative serum albumin levels had s significantly greater incidence of MACEs than did those with high preoperative serum albumin levels (23.2% versus 19.5%, P = 0.013).ConclusionIn summary, high baseline &Alb levels are an independent risk factor for CI-AKI in patients after PCI. The occurrence of CI-AKI in the perioperative period is also an independent predictor of long-term prognosis after PCI. These findings highlight the importance of monitoring &Alb levels and taking steps to prevent CI-AKI in patients undergoing PCI.

Development and internal validation of machine-learning models for predicting survival in patients who underwent surgery for spinal metastases.

A retrospective study. This study aimed to develop machine-learning algorithms for predicting survival in patients who underwent surgery for spinal metastasis. This study develops machine-learning models to predict postoperative survival in spinal metastasis patients, filling the gaps of traditional prognostic systems. Utilizing data from 389 patients, the study highlights XGBoost and CatBoost algorithms̓ effectiveness for 90, 180, and 365-day survival predictions, with preoperative serum albumin as a key predictor. These models offer a promising approach for enhancing clinical decision-making and personalized patient care. A registry of patients who underwent surgery (instrumentation, decompression, or fusion) for spinal metastases between 2004 and 2018 was used. The outcome measure was survival at postoperative days 90, 180, and 365. Preoperative variables were used to develop machine-learning algorithms to predict survival chance in each period. The performance of the algorithms was measured using the area under the receiver operating characteristic curve (AUC). A total of 389 patients were identified, with 90-, 180-, and 365-day mortality rates of 18%, 41%, and 45% postoperatively, respectively. The XGBoost algorithm showed the best performance for predicting 180-day and 365-day survival (AUCs of 0.744 and 0.693, respectively). The CatBoost algorithm demonstrated the best performance for predicting 90-day survival (AUC of 0.758). Serum albumin had the highest positive correlation with survival after surgery. These machine-learning algorithms showed promising results in predicting survival in patients who underwent spinal palliative surgery for spinal metastasis, which may assist surgeons in choosing appropriate treatment and increasing awareness of mortality-related factors before surgery.

The prognostic value of preoperative neoindices consisting of lymphocytes, neutrophils and albumin (LANR) in operable breast cancer: a retrospective study.

Preoperative inflammatory factors and nutritional status are strongly associated with the prognosis of a variety of cancers. We explored the relationship between preoperative lymphocytes, neutrophils and albumin (LANR) and progression-free survival in breast cancer patients. The clinical and follow-up data of 200 breast cancer patients were retrospectively analyzed in this study, and the value of LANR was determined as follows: LANR, lymphocytes × albumin/neutrophils. ROC curves, COX proportional risk regression analysis and subgroup analysis were used to assess the prognostic value of LANR in progression-free survival of breast cancer patients. The median age of the patients was 55.5 years (range 50-62 years). The median follow-up time was 46 months (range 33-55 months). In progression-free survival, the area under the LANR curve was 0.748 and the HR (95% CI) was 0.035 (0.679-0.817). LANR was associated with age (p=0.02), positive axillary lymph nodes (p<0.001), TNM stage (p<0.001) and human epidermal growth factor receptor 2(p=0.004). The results indicated that preoperative LANR may be a reliable predictor of progression-free survival in patients with operable breast cancer. LANR may be an essential predictor for breast cancer patients and provides a therapeutic basis for clinicians and patients.

Effect of Preoperative Neck Radiotherapy on the Reconstruction of Head and Neck Defects With the Supraclavicular Artery Island Flap.

Purpose: The supraclavicular artery island (SAI) flap is commonly used in the reconstruction of head and neck defects. However, the safety of SAI flaps for neck irradiated patient needs to be verified. To investigate the safety of using the SAI flap for patients who have undergone neck radiotherapy, as well as the risk factors for flap complications. Materials and Methods: Sixty-one patients (16 irradiated and 45 nonirradiated) with SAI flap-reconstructed head and neck defects were included, and relevant data were collected retrospectively. The gender, age, body mass index, presence of diabetes mellitus, preoperative albumin level, and flap size between irradiated and nonirradiated patients had no significant difference. Results: No significant difference was observed in the incidence of complications (total, mild, or severe) between the radiotherapy and nonradiotherapy groups. In univariate analysis, preoperative radiotherapy was not associated with postoperative complications of the SAI flap procedure (P = 1.00), while a low preoperative albumin level was a significant risk factor for postoperative complications (P < .05). Conclusions: Our data suggest that preoperative radiotherapy does not increase the risk of SAI flap postoperative complications compared with surgical reconstruction alone.

Prognostic significance of preoperative lymphocytes, albumin, and neutrophils (LANR) index in resectable pancreatic ductal adenocarcinoma

PurposeThe index composed of preoperative lymphocytes, albumin, and neutrophils (LANR), a new composite score based on inflammatory response and nutritional status, has been reported to be associated with the prognosis of multiple types of cancer, but the role of LANR in the prognosis of resectable pancreatic ductal adenocarcinoma (PDAC) has not yet been elucidated.Patients and methodsThe data of 142 patients with PDAC who underwent radical resection in the Affiliated Hospital of Jiangnan University from January 2015 to December 2018 were retrospectively analyzed. Receiver Operating Characteristic (ROC) curves were generated to determine the optimal cut-off values for these parameters, as well as the sensitivity and specificity of LANR in predicting survival. The Kaplan–Meier method was used to draw the survival curves. Log rank test was used for univariate analysis, and Cox proportional hazards regression model was used for multivariate analysis. ResultsThe optimal cut-off value of LANR was 18.145, and a low preoperative LANR was significantly correlated with the location of the tumor (p = 0.047). Multivariate analysis showed that tumor differentiation degree (HR:2.357, 95%CI:1.388–4.003,p = 0.002), lymph node metastasis (HR:1.755, 95%CI: 1.115–2.763, p = 0.015), TNM stage (HR:4.686, 95%CI: 2.958–7.425, p < 0.001), preoperative cancer antigen 19 − 9 levels (HR:1.001, 95%CI: 1.000-1.001, p < 0.001) and preoperative LANR (HR:0.221, 95%CI: 0.111–0.441, p < 0.001) were independent risk factors for a poor prognosis in patients undergoing radical resection of PDAC.ConclusionThis study found that preoperative LANR can be used to assess the prognosis of radical resection in patients with PDAC; those with low preoperative LANR had a worse outcome.

Risk factors and nomogram of clinically relevant pancreatic fistula after pancreaticoduodenectomy for periampullary cancer: A prospective multicenter cohort study

Abstract Background Clinically relevant postoperative pancreatic fistula (CRPF) is considered the most dangerous morbidity associated with pancreaticoduodenectomy (PD). The purpose of this study is to evaluate the risk factors and to construct a predicted model for CRPF after PD. Material and Methods Consecutive patients who underwent pancreaticoduodenectomy between August 2021 and October 2023 at Cho Ray Hospital and University Medical Center were included in a multicenter cohort research. Multivariate logistic regression analyses was used to identify the risk factors of CRPF, and a nomogram was built based on these factors. The value of the nomogram in predicting CRPF was evaluated using the area under the receiver operating characteristic (ROC) curve. Results There were 183 eligible patients in this study (mean age: 57.5 ± 12.6 years; 101 males), and the prevalence of CRPF was 13,7% overall. Multivariate analyses showed that, four risk factors related to CRPF, including preoperative serum albumin &lt;3.5 g/dl, body mass index (BMI) ≥ 25 kg/m2, soft texture of the pancreas and estimated blood loss ≥400 ml were prognostic factors for CRPF (p &lt; 0.05). We built a nomogram based on four variables to predict CRPF, and the area under the ROC curve for this nomogram was 0.855 (95% CI: 0,768 – 0,933). Conclusions Nomogram developed from four risk factors shows good performance to predict CRPF after PD. The clinical findings of this study will help surgeons identify perioperative risk factors for high-risk patients with pancreatic fistula who should be managed differently from other patients. Clinical Trial Registry number: ClinicalTrials.gov NCT05017207. Statement of Significance We successfully developed a nomogram to predict the risk of pancreatic fistula using four perioperative factors. By incorporating these risk factors into clinical practice, surgeons can develop appropriate treatment plans and interventions for high-risk patient populations, potentially reducing the morbidity associated with CRPF.

The Influencing Factors of Frailty and Quality of Life in Elderly Patients After Spinal Surgery.

To study the related factors of frailty and quality of life in elderly patients after spinal surgery. The anxiety, depression, frailty, and quality of life of all patients were assessed by the Anxiety screening scale (GAD-7), Depression screening scale (PHQ-9), Frailty screening scale (FRAIL), and European five-dimensional health scale (EQ-5D-5L) 1 day before surgery (DAY-0). A numeric rating scale (NRS) was used to evaluate patients' pain during activities on the 1st day (POD-1), 3rd day (POD-3), and 30th day (POD-30) after operation. FRAIL scale and EQ-5D-5L were used to evaluate patients' frailty and quality of life on POD-30 and 90th day (POD-90) after the operation. There were significant differences in age, body mass index (BMI), preoperative serum albumin level (ALB), and NRS score on POD-1 between the two groups (P<0.05). Age and PHQ-9 score were positively correlated with EQ-5D-5L score (P<0.05, r Age=0.245, rPHQ-9=0.217), and preoperative ALB level was negatively correlated with EQ-5D-5L score (P<0.05, r ALB=-0.274). The older the age, the larger the BMI and the higher the NRS score on the first day after surgery, the more prone to frailty in elderly patients after spinal surgery; The older age and the lower the preoperative ALB level, the worse the quality of life in elderly patients after spinal surgery.

Impact of Pretransplant C-Reactive Protein, Neutrophiles, Platelets, and Albumin Levels on Recipient Survival After Simultaneous Pancreas and Kidney Transplantation

BackgroundLong-lasting diabetes mellitus type 1 and end-stage renal disease induce severe metabolic and immunological deterioration. Pretransplant C-reactive protein (CRP) and albumin (ALB) levels have impact on kidney transplantation. We evaluated impact of preoperative CRP, ALB, neutrophiles (NEU) and platelets (PLT) count, on one- and five-year recipients survival after simultaneous pancreas and kidney transplantation (SPK). MethodsAmong 103 SPK recipients, parameters: CRP (mean: 4.5±4.97mg/L); NEU (mean: 5.12 ±2.13∗103/mm3); PLT (mean: 244±84∗103/mm3); ALB (mean 4.5±0.75 g/dL) were obtained before transplantation. Cox regression, uni-, multivariate analysis for one- and five-year survivals were performed with 95% Confidence Intervals (CI) and area under ROC curve (AUC) was assessed. ResultsIn Cox regression, ALB <3,65g/dL had significant impact for one-year and five-year survivors with hazard ratios: 8 (CI:1.5-38.28, p<0.05) and 3.13 (CI:1.45-6.73, p<0.05), respectively. In univariate analysis, we found significantly decreased one-year survival if: PLT<180∗103/mm3, ALB <3.65g/dL, NEU>5.8∗103/mm3 and CRP>2.25mg/L with odds ratios (OR): 6.75 (CI: 2.12-21.15); 4.05(CI:1.3-12.09); 2.97 (CI: 1.02-8.64) and 5.51 (CI:1.67-18.19), respectively. Independent factors for five-year survival were: CRP, ALB and PLT with OR: 4.72(CI:1.67–13.29); 3.31(CI:1.18–9.25) and 4.2(CI:1.39–12.68), respectively. In multivariate analysis, we built two models for one-year survival. Model 1 (ALB+PLT) with OR: 3.12 (CI:0.97-10.07) and 5.55 (CI:1.67-18.4); and model 2 (CRP+PLT) with OR: 5.51 (CI:1.5-17.3) and 4.3 (CI:1.2-15.06), respectively. AUC for models 1 and 2 were: 0.74 and 0.759, respectively. ConclusionsNEU, PLT, ALB and CRP levels assessed before transplantation are independent factors for one- and five-year SPK recipients survival.

Severe hypoalbuminemia complicating a successful atrial switch operation (Senning) with cardiopulmonary bypass - report on a rare case

Post-operative hypoalbuminemia has been reported in 12% of neonates and 20% of infants; 97% occurs in the first 48 hours in neonates and infants undergoing cardiac surgery with cardiopulmonary bypass (CPB). Perioperative hypoalbuminemia is not independently associated with any post-operative morbidity. However, when analysed as a continuous variable, lower serum albumin levels have been reported to be associated with increased post-operative morbidity. Pre-operative low serum albumin level is independently associated with increased odds of post-operative hypoalbuminemia, and prolonged length of hospital stay. Immediate post-CPB (0-24 hour), lower serum albumin level is independently associated with an increased duration of mechanical ventilation. There is a relative paucity of literature on the impact of hypoalbuminemia in the paediatric population. Hypoalbuminemia is a marker of poor outcome in critically ill children and those undergoing a wide range of medical interventions. Albumin infusions may be an effective therapy for fluid resuscitation and for patients with severe hypoalbuminemia. We present a successful perioperative management of a 3 months old-male child, weighing 3.5 kg with dextro-transposition of great arteries (D-TGA) with regressed LV undergoing an atrial switch (Senning) procedure, and uneventful intraoperative course i.e. easy weaning from CPB. However, in the ICU, the baby suffered an unusual complication as severe hypoproteinaemia resulting in acute kidney injury (AKI) with complete anuria, generalized anasarca, hypotension requiring inotropes and vasopressors, and difficult weaning from ventilator.

Predictors of Timely Initiation and Completion of Adjuvant Chemotherapy in Stage II/III Colorectal Adenocarcinoma.

Background: Adjuvant chemotherapy (AC) for colorectal cancer (CRC) has led to substantial improvement in survival. Several clinical trials advocate the initiation of AC within 6-8 weeks of surgical resection based on evidence of improved survival with early initiation of AC. We aim to evaluate factors that predict initiation and completion of AC, subsequently improving survival. Methods: We identified 451 patients who underwent resection for CRC between 2014 and 2022. One hundred ten patients had stage II/III colorectal cancer who underwent resection followed by AC. Multivariable logistic regression analysis was performed to identify factors significantly predicting delay in AC >8 weeks. Secondary outcomes included chemotherapy completion rate, recurrence-free survival, and overall survival. Results: The final analysis included 110 patients. The median time to initiation of adjuvant chemotherapy (TIAC) was 6.9 weeks (IQR: 5.8-9.5). In total, 36.4% of patients had a delay >8 weeks to initiation of AC, and only 40% completed treatment. The surgical approach (open vs laparoscopic vs robotic) had no effect on the TIAC. On multivariable logistic regression analysis, preoperative albumin ≥3.5 (OR = .31; 95% CI: .12-.80) was an independent predictor of timely initiation of AC. Completion of AC was associated with a higher overall survival. Discussion: Preoperative nutritional status predicted delay in initiation of AC. Patients with a delay in AC beyond eight weeks had a lower rate of AC completions and worse survival. It is imperative to optimize this aspect of treatment as it correlates with survival.
