Perioperative changes of serum albumin are a predictor of postoperative pulmonary complications in lung cancer patients: a retrospective cohort study

Albumin Leakage Level during Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy Is Associated with Major Complications

The clinical consequences of perioperative albumin extravasation accompanying major abdominal surgery remain underexplored. We retrospectively reviewed the data of patients who underwent cytoreductive surgery (CRS) and hyperthermic intraoperative peritoneal chemotherapy (HIPEC). Parameters of albumin kinetics, including serum albumin concentration decrease (∆Alb) and extravasated albumin level (Albshift), were assessed from surgery until postoperative day (POD) 3. Logistic regression analysis identified factors associated with major complications. The association of albumin kinetics with major complications was evaluated using receiver operating characteristic (ROC) curve analysis. Serum albumin levels decreased during surgery and subsequently increased. Of the 121 analyzed patients, 25 (21%) developed major complications. The ∆Alb and Albshift during surgery and on POD 3 were greater in patients who developed major complications than in those who did not (12 ± 12 vs. 6 ± 14, p = 0.032, and 127.5 (71.9) vs. 48.5 (44.9), p < 0.001, respectively). Perioperative ∆Alb and Albshift were associated with major complications. The areas under the ROC curve of Albshift during the 3 days post-surgery and Albshift on POD 3 were 0.843 and 0.910, respectively. Albshift during the 3 days post-surgery and Albshift on POD 3 were correlated with complications (p < 0.05). In conclusion, perioperative albumin loss was associated with major complications in patients undergoing CRS and HIPEC. Albshift was associated with serious complications.

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

OBJECTIVE

Contrast-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.

METHODS

A 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.

RESULTS

Of 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).

CONCLUSION

In 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.

Prognostic value of pretreatment modified Glasgow Prognostic Score in small cell lung cancer: A meta-analysis

BACKGROUND

The prognostic role of pretreatment modified Glasgow Prognostic Score (mGPS) in small cell lung cancer (SCLC) patients remains unclear now.

METHODS

The PubMed, EMBASE, Web of Science, and CNKI electronic databases were searched up to December 14, 2022. The primary and secondary outcomes were overall survival and progression-free survival, respectively. The hazard ratios (HRs) and 95% confidence intervals (CIs) were combined to assess the association between pretreatment mGPS and survival of SCLC patients. Subgroup analysis based on the country, tumor stage, treatment and comparison of mGPS were further conducted and all statistical analyses were performed by STATA 15.0 software.

RESULTS

A total of ten retrospective studies involving 2831 SCLC patients were included. The pooled results demonstrated that elevated pretreatment mGPS was significantly related to poorer overall survival (HR = 1.90, 95% CI: 1.36-2.63, P < .001) and progression-free survival (HR = 1.40, 95% CI: 1.13-1.74, P = .002). Subgroup analysis stratified by the country, tumor stage, treatment and comparison of mGPS also showed similar results.

CONCLUSION

Pretreatment mGPS was significantly associated with prognosis in SCLC and patients with elevated mGPS experienced obviously worse survival. Thus, pretreatment mGPS could serve as a novel and reliable prognostic indicator in SCLC patients.

Relative decline in serum albumin help to predict anastomotic leakage for female patients following sphincter-preserving rectal surgery

BACKGROUND

Patients with normal preoperative serum albumin still suffer from a significant reduction in serum albumin after major abdominal surgery. The current study aims to explore the predictive value of ∆ALB for AL in patients with normal serum albumin and examine whether there is a gender difference in the prediction of AL.

METHODS

Medical reports of consecutive patients undergoing elective sphincter-preserving rectal surgery between July 2010 and June 2016 were reviewed. Receiver operating characteristic (ROC) analysis was adopted to examine the predictive ability of ∆ALB and determine the cut-off value according to the Youden index. The logistic regression model was performed identify independent risk factors for AL.

RESULTS

Out of the 499 eligible patients, 40 experienced AL. Results of the ROC analyses showed that ΔALB displayed a significant predictive value for females, and the AUC value was 0.675 (P = 0.024), with a sensitivity of 93%. In male patients, the AUC was 0.575 (P = 0.22), but did not reach a significant level. In the multivariate analysis, ∆ALB ≥ 27.2% and low tumor location prove to be independent risk factors for AL in female patients.

CONCLUSIONS

The current study suggested that there may be a gender difference in the prediction of AL and ∆ ALB can serve as a potential predictive biomarker for AL in females. A cut-off value of the relative decline in serum albumin can help predict AL in female patients as early as postoperative day 2. Although our study needs further external validation, our findings may provide an earlier, easier and cheaper biomarker for the detection of AL.

An algorithm based on the postoperative decrease of albumin (ΔAlb) to anticipate complications after liver surgery

Background

Perioperative decrease of albumin (ΔAlb) appeared as a promising predictor of complications after digestive surgery, but its role after liver surgery remains unclear. This study aimed to analyze whether and how ΔAlb can be used to predict complications after liver surgery.

Methods

A bicentric retrospective analysis of patients undergoing liver surgery (2010–2016) was performed, following TRIPOD guidelines. The preoperative and postoperative difference of albumin was calculated on POD 0 and defined as ΔAlb. Patients with any missing variable were excluded. The primary endpoint was overall complications according to the Clavien classification. A multiparametric algorithm based on ΔAlb was generated to optimize prediction performance.

Results

A total of 110 patients were analyzed. At least one complication occurred in 66 (60%) patients. Patients with and without complication showed a ΔAlb of 15.8 vs. 9.5 g/L (p<0.001). Area under ROC curve (AUC) of ΔAlb was 0.75 (p<0.01.). The ΔAlb-based algorithm showed an AUC of 0.84 (p<0.01), significantly improving performance (p=0.03). Multivariable analysis identified ΔAlb as independent predictor of complications (HR, 1.12; 95% CI, 1.01–1.07; p = 0.002).

Conclusions

ΔAlb appeared as a promising predictor independently associated with the risk of complication after liver surgery. The study presents a novel decision-tree based on ΔAlb to anticipate complications.

Effect of integrated management bundle on 1-year overall survival outcomes and perioperative outcomes in super elderly patients aged 90 and over with hip fracture: non-concurrent cohort study

BACKGROUND

Due to concomitant factors like frailty and comorbidity, super elderly (≥90 years) patients with hip fracture differ from patients aged 65-89 years in perioperative complications and mortality. The integrated management bundle referred to bundled application of multiple clinical measures. The aim of this study was to analyze effect of integrated management bundle on 1-year overall survival and perioperative outcomes in super elderly patients with hip fracture, with multidisciplinary management group serving as the control group.

METHODS

In this retrospective cohort study, super elderly patients with hip fracture were included from Jan 2017 to Nov 2020. Patients were retrospectively divided to multidisciplinary management group and integrated management bundle group. The primary outcome was 1- year overall survival, and the secondary outcome was perioperative outcomes. Kaplan-Meier methods was used to compare survival probability. Multivariable Cox's modeling was used to explain the effect of integrated bundle on 1-year overall survival adjusted for confounders. The perioperative outcomes including complications and in-hospital data of two groups were compared. The multivariable logistic regression was used to explain the effect of integrated bundle on the occurrence of perioperative complications adjusted for confounders. Prognostic factors related to survival was identified by multivariable Cox's regression analysis.

RESULTS

Ninety-seven patients comprised multidisciplinary management group, and 83 comprised integrated management bundle group. The Kaplan-Meier plots showed that the survival probability of integrated management bundle group was significantly better than multidisciplinary management group (HR:0.435, 95%CI:0.207-0.914, P = 0.039). Multivariable analysis after adjustment for confounders showed a 42.8% lower incidence of mortality integrated management bundle group than multidisciplinary management group (HR:0.428, 95%CI:0.186-0.986, P = 0.046). Incidence of hypoproteinemia, and electrolyte disturbance in integrated management bundle group was significantly lower than multidisciplinary management group (all P < 0.05). In addition, significant reduction was observed in length of stay (P < 0.05) in integrated management bundle group. Multivariable logistic regression showed integrated management bundle was independent protective factor of hypoproteinemia, and electrolyte disturbance. mECM score ≥ 6 and ASA score > 2 were independent risk factors of overall survival (HR: 1.940, 95%CI: 1.067-3.525,P = 0.030; HR: 2.281, 95%CI: 1.113-4.678,P = 0.024).

CONCLUSIONS

The integrated management bundle improved 1-year overall survival and played positive effects in improving perioperative outcomes. It might be a more suitable management modality for super elderly patients with hip fracture.

The effectiveness of ARISCAT Risk Index, other scoring systems, and parameters in predicting pulmonary complications after thoracic surgery

The Assess Respiratory Risk in Surgical Patients in Catalonia (ARISCAT) risk index, which is frequently used in nonthoracic surgery, may not be sufficient to predict postoperative pulmonary complications (PPCs). We aimed to evaluate the effectiveness of the ARISCAT risk index, ASA, preoperative albumin level, neutrophil/lymphocyte ratio (NLR), and other parameters in predicting PPCs after thoracic surgery. Patients undergoing elective thoracic surgery with 1-lung ventilation (OLV) were prospectively analyzed. Demographic data, ARISCAT score, ASA, Nutritional Risk Score-2002, NLR, white blood cell counts, albumin, hemoglobin levels, intraoperative complications, postoperative average visual analogue scale (VAS) score for pain at the 24th-hour, the length of stay in the postoperative intensive care unit, chest tube removal time, postoperative complications, and discharge time were recorded. Patients were assessed for morbidity and mortality on the 90th-day. 120 patients' data were analyzed. PPCs developed in 26 patients. The development of PPCs was statistically significant in patients with high ARISCAT scores (P = .002), high ARISCAT grades (P = .009), and ASA III (P = .002). The albumin level was statistically significantly lower in patients who had mortality within 3 months (P = .007). When scoring systems and laboratory parameters were evaluated together, patients with high ARISCAT grade, Albumin < 35g/L, and ASA III had significantly higher development of PPCs (P = .004). ARISCAT risk index and ASA were found to be significant in predicting PPCs after thoracic surgery. They were also valuable when evaluated in combination with preoperative albumin levels. Additionally; age, male gender, duration of surgery, and duration of OLV were also found to be associated with PPCs.

Incidence and Associated Factors of Postoperative Pulmonary Complications after Abdominal Surgery in the Public Hospital, Addis Ababa, Ethiopia

Background

Postoperative pulmonary complications are a wide variety of disorders that affect normal respiratory functions, which in turn lead to morbidity and mortality. The extent to which it occurs is not yet studied in most clinical settings. This study assessed the incidence and risk factors of postoperative pulmonary complications in patients undergoing abdominal surgery under general anesthesia.

Methods

A multicenter, prospective cross-sectional study was conducted at Menelik II, Tikur Anbessa Specialized, Zewditu Memorial, and Yekatit 12 Memorial hospitals after obtaining ethical clearance from each hospital. The study recruited a total of 287 participants using systematic random sampling. The data collection tool included sociodemographic, surgical, and anesthetic factors. Participants were followed for 7 days postoperatively, and any respiratory problems were recorded once identified. The collected data were entered and analyzed using SPSS version 26. Both bivariate and multivariate logistic regressions were used for analysis. A p value of <0.05 was considered statistically significant.

Results

About 33% of the participants that underwent abdominal surgery developed postoperative pulmonary complications. Age > 65 years (AOR = 12.091, 95% CI = 3.310–44.169), duration of surgery >3 hours (AOR = 11.737, 95% CI = 3.621–38.039), preoperative oxygen saturation <94% (AOR = 10.671, 95% CI = 3.794–30.016), and postoperative serum albumin level <3.5 g/dl (p value <0.001) were associated with postoperative pulmonary complications significantly. Conclusion and Recommendations. The incidence of postoperative pulmonary complications after abdominal surgeries was high. Age >65years, duration of surgery >3 hours, preoperative SpO2% <94%, cigarette smoking, and postoperative serum albumin level <3.5 g/dl were factors strongly associated with postoperative pulmonary complications. We recommend special care for elderly patients, limit the surgical duration to less than 3 hours, treat the underlying cause of desaturation, and correct postoperative serum albumin to prevent the occurrence of postoperative pulmonary complications.

Serum protein and electrolyte imbalances are associated with chemotherapy induced neutropenia

Introduction

Cancer and its treatment using various chemotherapeutic agents can have many adverse side effects. These side effects often result in significant changes in haematological and biochemical composition of blood. As a result, the regular monitoring of serum biochemical and haematological changes plays an important role in management of disease. The present study aimed to determine the relationship between haematological and biochemical changes in neutropenic cancer patients following chemotherapy. Specifically we evaluated the association between neutrophil count and serum proteins and electrolytes.

Methods

For this purpose we analysed retrospectively collected laboratory results from two independent patient cohorts. Each cohort was divided into a control group consisting of patients with normal haematological parameters and a study group which included patients with reduced neutrophil counts. Neutropenic patients (study group) were cancer patients on chemotherapy.

Results and conclusion

Blood samples of cancer patients in study group showed reduction in haemoglobin, neutrophils and platelets. Neutropenic group showed a significant reduction in serum albumin, total protein, calcium, and potassium. Our results show that patients with severe neutropenia had pronounced changes in serum protein and electrolytes and increased incidence of abnormal serum protein and electrolyte level. The changes in the neutrophil counts showed a positive correlation with the changes in serum protein and electrolyte levels. A similar trend was seen in both the patient cohorts: the discovery set (176 patients) and the validation set (200 patients). Taken together our results suggest that chemotherapy-induced neutropenia is associated with dysregulation in haemoglobin, platelets, serum proteins and electrolytes.

Relationship Between Preoperative Hypoalbuminemia and Postoperative Pneumonia Following Geriatric Hip Fracture Surgery: A Propensity-Score Matched and Conditional Logistic Regression Analysis

Background

Pneumonia is a devastating complication following geriatric hip fracture surgery, and preoperative hypoalbuminemia may be a potentially modifiable factor leading to improved outcome. This study aimed to quantify the relationship between preoperative hypoalbuminemia and postoperative pneumonia.

Methods

We retrospectively reviewed the medical records of elderly patients (≥60 years) who underwent surgeries for hip fracture in a tertiary referral center between 2016 and 2020. According to the preoperative serum albumin level, they were divided into two groups: <35 g/ L and ≥35 g/ L. To reduce potential confounding, propensity score matching (PSM) in a 1:1 ratio was performed, with the caliper value set as 0.002; and further conditional logistic regression analysis was used to control the other potential confounders to determine the association strength.

Results

Among 3,147 eligible patients included, PSM yielded 1,318 matched patients, with 659 in each respective group, suggesting significantly improved balance in most variables (standardized mean deviation improvement range, 20.7% to 99.1%), except for basophil count. The conditional logistic regression analysis, adjusted for PS and other intra- or post-operative variables, showed 6.18-fold (relative ratio, 6.18; 95% CI, 3.15–11.98; P<0.001) increased risk of postoperative pneumonia associated with preoperative hypoalbuminemia.

Conclusion

Preoperative hypoalbuminemia was identified to be independently and highly associated with development of postoperative pneumonia in elderly patients undergoing hip fracture surgeries. However, whether the patients who had such condition may benefit from preoperative targeted nutritional support needs to be clarified by more prospective studies.

Using Nomograms to Predict the PPCs of Patients With Diffuse Peritonitis Undergoing Emergency Gastrointestinal Surgery

Objective: To develop and validate a nomogram model for predicting postoperative pulmonary complications (PPCs) in patients with diffuse peritonitis undergoing emergency gastrointestinal surgery.

Methods: We used the least absolute shrinkage and selection operator (LASSO) regression model to analyze the independent risk factors for PPCs in patients with diffuse peritonitis who underwent emergency gastrointestinal surgery. Using R, we developed and validated a nomogram model for predicting PPCs in patients with diffuse peritonitis undergoing emergency gastrointestinal surgery.

Results: The LASSO regression analysis showed that AGE, American Society of Anesthesiologists physical status classification (ASA), DIAGNOSIS, platelets (on the 3rd day after surgery), cholesterol (on the 3rd day after surgery), ALBUMIN (on the first day after surgery), and preoperative ALBUMIN were independent risk factors for PPCs in patients with diffuse peritonitis undergoing emergency gastrointestinal surgery. The area under the curve (AUC) value of the nomogram model in the training group was 0.8240; its accuracy was 0.7000, and its sensitivity was 0.8658. This demonstrates that the nomogram has a high prediction value. Also in the test group, the AUC value of the model established by the variables AGE, ASA, and platelets (on the 3rd day after surgery), cholesterol (on the 3rd day after surgery), ALBUMIN (on the first day after surgery), and preoperative ALBUMIN was 0.8240; its accuracy was 0.8000; and its specificity was 0.8986. In the validation group, the same results were obtained. The results of the clinical decision curve show that the benefit rate was also high.

Conclusion: Based on the risk factors AGE, ASA, DIAGNOSIS, platelets (on the 3rd day after surgery), cholesterol (on the 3rd day after surgery), ALBUMIN (on the first day after surgery), and preoperative ALBUMIN, the nomogram model established in this study for predicting PPCs in patients with diffuse peritonitis undergoing emergency gastrointestinal surgery has high accuracy and discrimination.

Prognostic value of postoperative decrease in serum albumin on surgically resected early-stage non-small cell lung carcinoma: A multicenter retrospective study

Background

Preoperative nutritional status is an important host-related prognostic factor for non-small cell lung carcinoma (NSCLC); however, the significance of postoperative changes in nutritional status remains unclear. This study aimed to elucidate the significance of postoperative decreases in serum albumin (ΔAlb) on the outcomes of early-stage NSCLC.

Methods

We analyzed 443 training cohort (TC) and 642 validation cohort (VC) patients with pStage IA NSCLC who underwent surgery and did not recur within 1 year. We measured preoperative serum albumin levels (preAlb) and postoperative levels 1 year after surgery (postAlb), and calculated ΔAlb as (preAlb − postAlb)/preAlb × 100%. A cutoff value of 11% for ΔAlb was defined on the basis of the receiver operating characteristic curve for the TC.

Results

Patients were divided into ΔAlb-Decreased and ΔAlb-Stable groups, including 100 (22.6%) and 343 (77.4%) in the TC, and 58 (9.0%) and 584 (90.1%) in the VC. ΔAlb-Decreased was associated with male sex (p = 0.0490), smoking (p = 0.0156), and non-adenocarcinoma (p<0.0001) in the TC, and pT1b (p = 0.0169) and non-adenocarcinoma (p = 0.0251) in the VC. Multivariable analysis identified ΔAlb as an independent prognostic factor for disease-free survival (DFS) and overall survival (OS) in both cohorts (VC: DFS, HR = 1.9, 95%CI: 1.10–3.15, p = 0.0197; OS, HR = 2.0, 95%CI: 1.13–3.45, p = 0.0173). Moreover, subgroup analysis demonstrated that the prognostic value of ΔAlb was consistent for age, sex, smoking history, surgical procedure, and histological type.

Conclusion

We demonstrated a negative impact of postoperative decrease of the serum albumin on the prognosis of patients with early-stage NSCLC. Postoperative changes in nutritional status might be important in NSCLC outcomes.

Developing Machine Learning Algorithms to Predict Pulmonary Complications After Emergency Gastrointestinal Surgery

Objective: Investigate whether machine learning can predict pulmonary complications (PPCs) after emergency gastrointestinal surgery in patients with acute diffuse peritonitis.

Methods: This is a secondary data analysis study. We use five machine learning algorithms (Logistic regression, DecisionTree, GradientBoosting, Xgbc, and gbm) to predict postoperative pulmonary complications.

Results: Nine hundred and twenty-six cases were included in this study; 187 cases (20.19%) had PPCs. The five most important variables for the postoperative weight were preoperative albumin, cholesterol on the 3rd day after surgery, albumin on the day of surgery, platelet count on the 1st day after surgery and cholesterol count on the 1st day after surgery for pulmonary complications. In the test group: the logistic regression model shows AUC = 0.808, accuracy = 0.824 and precision = 0.621; Decision tree shows AUC = 0.702, accuracy = 0.795 and precision = 0.486; The GradientBoosting model shows AUC = 0.788, accuracy = 0.827 and precision = 1.000; The Xgbc model shows AUC = 0.784, accuracy = 0.806 and precision = 0.583. The Gbm model shows AUC = 0.814, accuracy = 0.806 and precision = 0.750.

Conclusion: Machine learning algorithms can predict patients' PPCs with acute diffuse peritonitis. Moreover, the results of the importance matrix for the Gbdt algorithm model show that albumin, cholesterol, age, and platelets are the main variables that account for the highest pulmonary complication weights.

Early Postoperative Hypoalbuminaemia as a Risk Factor for Postoperative Pneumonia Following Hip Fracture Surgery

Purpose

Postoperative pneumonia is a common and devastating complication of hip fracture surgery in older individuals. This study aimed to determine the relationship between early postoperative hypoalbuminaemia and pneumonia after hip fracture surgery.

Patients and Methods

In this retrospective cohort study conducted at one centre, we reviewed the medical records of 1155 consecutive patients (>60 years) who underwent hip fracture surgery. Multivariate logistic regression analysis was performed to identify the independent risk factors for postoperative pneumonia. After determining the cut-off value for postoperative serum albumin, the patients were divided into two groups according to the minimum serum albumin level recorded during the first two postoperative days: group A included patients with a minimum serum album level less than 3.0 g/dL and group B included patients with a minimum serum album level of at least 3.0 g/dL. The prevalence of postoperative pneumonia was analysed using inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) analyses.

Results

The incidence of postoperative pneumonia following hip fracture surgery was 5.1% (n=59). Age, cardiovascular disease, and early postoperative hypoalbuminaemia during the first two postoperative days were independent risk factors for postoperative pneumonia. Early postoperative hypoalbuminaemia was associated with postoperative pneumonia development in the PSM and IPTW analyses (P = 0.016 and <0.001, respectively).

Conclusion

This study demonstrated that early postoperative hypoalbuminaemia is an independent risk factor for the development of postoperative pneumonia in patients undergoing hip fracture surgery.

Preoperative Serum Albumin Level As A Predictor Of Postoperative Pneumonia After Femoral Neck Fracture Surgery In A Geriatric Population

Purpose

Femoral neck fracture usually occurs in the geriatric population. Postoperative pneumonia (POP) is known to be devastated, and it is the most frequent complication among patients receiving surgical treatment for femoral neck fractures. However, whether patients who have hypoalbuminaemia are susceptible to the development of POP is a serious concern, although it has not been investigated. We attempted to investigate the association between newly developed POP and hypoalbuminaemia and to identify whether hypoalbuminaemia is an independent risk factor for POP after femoral neck fracture in geriatric population.

Patients and methods

We retrospectively reviewed the records from the first 30 days after surgery of patients who were ≥65 years of age and who had a femoral neck fracture treated with surgery between January 2018 and December 2018 at the Honghui Hospital, Xi’an Jiaotong University. Patients were divided into two groups based on whether they did or did not experience POP, and their clinical characteristics were compared. Binomial logistic regression was used to identify potential risk factors of POP by analysing demographic factors, preoperative comorbidities, laboratory results, and surgical factors.

Results

A total of 720 patients were included in the analysis, and 54 patients experienced POP. The incidence of POP after surgical treatment for a femoral neck fracture in this geriatric population was 7.5%. In addition, patients with POP had significantly longer hospital stays than patients without POP. The binary logistic regression analysis revealed that preoperative hypoalbuminaemia [odds ratio =5.187, 95% confidence interval (CI): 2.561–10.506, P<0.0001], COPD (OR =3.819, 95% CI: 1.247–11.701, P=0.019), prior stroke (OR =3.107, 95% CI: 1.470–6.568, P=0.003) and the time from injury to surgery (OR =1.076, 95% CI: 1.034–1.119, P<0.0001) were predominant and independent risk factors associated with POP after femoral neck fracture in this geriatric population.

Conclusion

The current study revealed that among a geriatric population admitted for femoral neck fracture surgery, preoperative hypoalbuminaemia was a predictor of POP, followed by COPD, prior stroke and the time from injury to surgery. Thus, patients who undergo femoral neck fracture surgery and have preoperative hypoalbuminaemia should receive additional monitoring and perioperative care.

The Prognostic Significance Of Pretreatment Albumin/alkaline Phosphatase Ratio In Patients With Stage IB-IIA Cervical Cancer

Background

Pretreatment albumin/alkaline phosphatase ratio (AAPR) has been discussed about its prognostic value in several malignancies, whereas its role in cervical cancer remains unclear. In this study, we attempt to explore the prognostic significance of the AAPR in stage IB-IIA cervical cancer patients who underwent a radical hysterectomy.

Patients and methods

A total of 230 cervical cancer patients were enrolled in this retrospective study. The threshold value of AAPR was determined by receiver operating characteristic (ROC) curve. Kaplan-Meier survival analysis and multivariate analysis were performed to identify independent prognostic predictors of disease-free survival (DFS) and overall survival (OS).

Results

The optimal cut-off value of the preoperative AAPR was 0.68. Patients with AAPR<0.68 showed obviously inferior OS and DFS than those with AAPR>0.68 according to Kaplan-Meier curves (DFS: P = 0.011; OS: P = 0.017). In multivariate analysis, the preoperative AAPR showed to be an independent predictive factor for disease-free survival (DFS: P = 0.015) and overall survival (OS: P = 0.019). Moreover, subgroup analysis revealed that the lower AAPR was correlated with worse prognosis in patients with histologic grade I-II; but in those with histologic grade III, there was no significant difference between the two groups.

Conclusion

Preoperative AAPR was a potentially valuable prognostic index in stage IB-IIA cervical cancer patients. Further prospective studies are required to validate its prognostic value.
