Association between hypoalbuminemia and surgical site infection in vulvar cancers

Application of Negative-Pressure Wound Therapy in Patients with Wound Complications after Flap Repair for Vulvar Cancer: A Retrospective Study

OBJECTIVE

To analyze the characteristics of postoperative wound complications (WCs) in patients following vulvectomy with flap repair and evaluate the efficacy of negative-pressure wound therapy (NPWT) in wound healing.

METHODS

This study retrospectively reviewed 17 patients with WCs following vulvectomy with flap repair at a tertiary comprehensive hospital from January 2016 to December 2022. All patients were treated with NPWT, and the wound healing rate, healing time, and NPWT-related complications were observed.

RESULTS

The most common WCs were seroma and lymphorrhea (52.94%; nine cases), followed by wound infection (35.29%, six cases), fat liquefaction (23.53%, four cases), wound dehiscence (17.65%, three cases), and wound ischemia (5.88%, one case). The main locations for flap WCs were the vulva (64.71%), thigh (35.29%), and pubic symphysis (23.53%). One patient halted treatment; the remaining 16 patients all achieved complete healing with a mean healing time of 43.50 ± 17.92 days. One complication was associated with the use of NPWT: procedural pain (17.65%, three cases).

CONCLUSIONS

The use of NPWT may contribute to accelerated wound healing after flap repair in vulvar cancer and is safe for clinical application.

Analysis of the associated factors in postoperative wound infection following open reduction and internal fixation for elbow fracture

Postoperative wound infections (PWIs) following open reduction and internal fixation (ORIF) for elbow fractures can significantly affect patient outcomes. Identifying associated risk factors is crucial for improving clinical practices and patient care. A retrospective analysis (June 2020-June 2023) at our institution involved 90 patients who underwent elbow ORIF. Thirty patients developed PWIs (case group), compared to 60 who did not (control group). Variables like anaemia, operation duration, hospital stay, blood loss, body mass index (BMI), age, hypoalbuminemia, smoking status, diabetes mellitus and open fractures were examined. Univariate and multivariate analyses determined the impact of these variables on PWI incidence, with statistical significance set at p < 0.05. The main pathogens identified were Escherichia coli among Gram-negative bacteria (59.46%) and Staphylococcus aureus among Gram-positive bacteria (40.54%). In the univariate analysis, hypoalbuminemia, anaemia, and lifestyle factors such as smoking showed higher prevalence in patients with PWIs. However, age and length of hospital stay did not significantly influence infection rates. The multivariate analysis further elucidated that anaemia, smoking, diabetes mellitus and open fractures were independent, significant predictors of PWIs. These findings highlight the complexity of factors influencing infection risk post-ORIF, underscoring the importance of both individual health conditions and surgical complications in patient outcomes. Anaemia, smoking, diabetes mellitus and open fractures significantly increase the risk of PWI after elbow ORIF. Early identification and management of these risk factors are imperative to reduce infection rates and improve postoperative recovery.

The modified 5-item frailty index is a predictor of post-operative complications in vulvar cancer: a National Surgical Quality Improvement Program (NSQIP) analysis

OBJECTIVE

To determine whether frailty is associated with post-operative complications following surgery for vulvar cancer.

METHODS

This retrospective study used a multi-institutional dataset from the National Surgical Quality Improvement Program (NSQIP) database (2014-2020) to analyze the relationship between frailty, procedure type, and post-operative complications. Frailty was determined using the modified frailty index-5 (mFI-5). Univariate and multivariable-adjusted logistic regression analyses were performed.

RESULTS

Of 886 women, 49.9% underwent radical vulvectomy alone, and 19.5% and 30.6% underwent concurrent unilateral or bilateral inguinofemoral lymphadenectomy, respectively; 24.5% had mFI ≥2 and were considered frail. Compared with non-frail women, those with an mFI ≥2 were more likely to have an unplanned readmission (12.9% vs 7.8%, p=0.02), wound disruption (8.3% vs 4.2%, p=0.02), and deep surgical site infection (3.7% vs 1.4%, p=0.04). On multivariable-adjusted models, frailty was a significant predictor for minor (OR 1.58, 95% CI 1.09 to 2.30) and any complications (OR 1.46, 95% CI 1.02 to 2.08). Specifically, for radical vulvectomy with bilateral inguinofemoral lymphadenectomy, frailty was significantly associated with major (OR 2.13, 95% CI 1.03 to 4.40) and any complications (OR 2.10, 95% CI 1.14 to 3.87).

CONCLUSION

In this analysis of the NSQIP database, nearly 25% of women undergoing radical vulvectomy were considered frail. Frailty was associated with increased post-operative complications, especially in women concurrently undergoing bilateral inguinofemoral lymphadenectomy. Frailty screening prior to radical vulvectomy may assist in patient counseling and improve post-operative outcomes.

Evidence-based guideline for the prevention and management of perioperative infection

BACKGROUND

We have updated the guideline for preventing and managing perioperative infection in China, given the global issues with antimicrobial resistance and the need to optimize antimicrobial usage and improve hospital infection control levels.

METHODS

We conducted a comprehensive evaluation of the evidence for prevention and management of perioperative infection, based on the concepts of the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. The strength of recommendations was graded and voted using the Delphi method and the nominal group technique. Revisions were made to the guidelines in response to feedback from the experts.

RESULTS

There were 17 questions prepared, for which 37 recommendations were made. According to the GRADE system, we evaluated the body of evidence for each clinical question. Based on the meta-analysis results, recommendations were graded using the Delphi method to generate useful information.

CONCLUSIONS

This guideline provides evidence to perioperative antimicrobial prophylaxis that increased the rational use of prophylactic antimicrobial use, with substantial improvement in the risk-benefit trade-off.

Hypoalbuminemia and colorectal cancer patients: Any correlation?: A systematic review and meta-analysis

BACKGROUND

In malnourished patients with colorectal cancer, hypoalbuminemia is common and was proposed to determine the postoperative outcome of colorectal surgery. Mounting articles published but have not been evaluated. We aim to assess the predictive value of preoperative hypoalbuminemia in patients undergoing colorectal surgery.

METHODS

We performed a literature search from PubMed, Euro PMC, and Cochrane with the terms serum albumin, hypoalbuminemia, prognosis, outcome, colorectal cancer, and neoplasm. We also hand-searched and included any relevant papers. Hypoalbuminemia is defined as plasma albumin level < 3.5 mg/dL. We restricted the included studies to English language and adults undergoing colectomy, laparotomy, laparoscopy, or abdominoperineal resection. Any types of articles were included, except an abstract-only publication and those that did not report the key exposure or outcome of interest. The key exposures were mortality, hospitalization time, and morbid conditions (thrombosis, surgical site infection, sepsis, and wound events). We pooled the odds ratio from each included literature as effect size. The Newcastle Ottawa scale and GRADE were used to determine the quality of each included study.

RESULTS

Hereof 7 observational studies (236,480 individuals) were included. Our meta-analysis found that preoperative hypoalbuminemia can predict the postoperative outcome in colorectal cancer patients. Individuals with hypoalbuminemia were not associated with 30-day mortality (risk ratio [RR] 2.05 [0.72, 5.86], P = .18, I2 = 99%) but were associated with morbidity (RR 2.28 [1.78, 2.93], P < .00001, I2 = 87.5%), surgical complication (RR 1.69 [1.34, 2.13], P < .00001, I2 = 98%), and hospitalization (RR 2.21 [1.93, 2.52], P < .00001, I2 = 0%). According to newcastle ottawa scale, the included studies are of moderate to sound quality.

CONCLUSIONS

The current systematic review and meta-analysis showed that preoperative hypoalbuminemia was significantly associated with morbidity, length of stay, and surgical complication but not mortality.

The Prognostic Value of the Fibrinogen-Albumin-Ratio Index (FARI) in Patients with Advanced Vulvar Cancer

The present study aims to evaluate the pretherapeutic Fibrinogen-Albumin-Ratio Index (FARI), as currently reliable biomarkers to predict therapy response and prognosis of patients with advanced vulvar cancer are missing. Data of 124 consecutive patients, who underwent primary resection for vulvar cancer ≥ pT1b, were retrospectively analyzed. Associations between the FARI and disease recurrence were assessed fitting receiver operating characteristics (ROC) and binary logistic regression models; univariate and multivariable Cox regression models for disease-specific survival (DSS) and progression-free survival (PFS) were performed. A pretherapeutic low FARI cut at its median (<9.67) is significantly associated with younger age (65.5 vs. 74.0 years) and higher risk of recurrence (52.4% vs. 26.2%). The ROC analysis calculates the area under the curve (AUC) of the FARI for a PFS < 6 months of 0.700 and for a DSS < 12 months of 0.706, outperforming fibrinogen and albumin alone. The FARI remained independently predictive for PFS (HR 0.84, 95% CI [0.99−1.03], p = 0.009) and DSS (HR 0.82, 95% CI [0.70−0.99], p = 0.019), also in multivariable survival analysis. Despite the FARI’s promising predictive and prognostic value, however, further elucidation of its precise mode of action is warranted before clinical application as it appears to rely only on subtle changes of fibrinogen levels.

The role of preoperative albumin and white blood cell count in surgical site infections following whipple surgery

Whipple surgery is associated with a high risk of surgical sites infections (SSIs). Nutritional deficiency has been associated with an increased risk of wound infections. This study aims at exploring the role of preoperative albumin levels in predicting the risk of SSIs following Whipple surgery. A total of 23,808 individuals were identified from the ACS-NSQIP database from years 2011 to 2017. The primary exposure was pre-operative albumin while the secondary exposure was white blood cell (WBC) count. The primary outcome was divided into superficial and deep surgical site infections (S/D SSI) and organ-space SSI. All statistical analyses were conducted using IBM Statistical Package for Social Sciences version 26. Levels of pre-operative serum albumin less than 3.73 g/L, dirty and contaminated wounds and longer operative time were associated with increased odds for developing S/D SSIs (OR = 1.14, OR = 1.17, OR = 1.06, respectively, p-value < 0.05). Pre-operative WBC level (/L) was associated with a risk of developing an organ-space SSI but not S/D SSI (OR = 1.02, p-value  0.003). This study demonstrates the predictive role of pre-operative albumin in developing S/D SSIs and highlights the need to develop therapeutic strategies to optimize the pre-operative nutritional health status of patients undergoing Whipple surgery.

Pectin–Zeolite-Based Wound Dressings with Controlled Albumin Release

Hypoalbuminemia can lead to poor and delayed wound healing, while it is also associated with acute myocardial infarction, heart failure, malignancies, and COVID-19. In elective surgery, patients with low albumin have high risks of postoperative wound complications. Here, we propose a novel cost-effective wound dressing material based on low-methoxy pectin and NaA-zeolite particles with controlled albumin release properties. We focused on both albumin adsorption and release phenomena for wounds with excess exudate. Firstly, we investigated albumin dynamics and calculated electrostatic surfaces at experimental pH values in water by using molecular dynamics methods. Then, we studied in detail pectin–zeolite hydrogels with both adsorption and diffusion into membrane methods using different pH values and albumin concentrations. To understand if uploaded albumin molecules preserved their secondary conformation in different formulations, we monitored the effect of pH and albumin concentration on the conformational changes in albumin after it was released from the hydrogels by using CD-UV spectroscopy analyses. Our results indicate that at pH 6.4, BSA-containing films preserved the protein’s folded structure while the protein was being released to the external buffer solutions. In vitro wound healing assay indicated that albumin-loaded hydrogels showed no toxic effects on the fibroblast cells.

Association between postoperative hypoalbuminemia and postoperative pulmonary imaging abnormalities patients undergoing craniotomy for brain tumors: a retrospective cohort study

Hypoalbuminemia is associated with poor outcome in patients undergoing surgery intervention. The main aim for this study was to investigate the incidence and the risk factors of postoperative hypoalbuminemia and assessed the impact of postoperative hypoalbuminemia on complications in patients undergoing brain tumor surgery. This retrospective study included 372 consecutive patients who underwent brain tumors surgery from January 2017 to December 2019. The patients were divided into hypoalbuminemia (< 35 g/L) and non-hypoalbuminemia group (≥ 35 g/L) based on postoperative albumin levels. Logistic regression analyses were used to determine risk factors. Of the total 372 patients, 333 (89.5%) developed hypoalbuminemia after surgery. Hypoalbuminemia was associated with operation time (OR 1.011, P < 0.001), preoperative albumin (OR 0.864, P = 0.015) and peroperative globulin (OR 1.192, P = 0.004). Postoperative pulmonary imaging abnormalities had a higher incidence in patients with than without hypoalbuminemia (41.1% vs 23.1%, P = 0.029). The independent predictors of postoperative pulmonary imaging abnormalities were age (OR 1.053, P < 0.001), operation time (OR 1.003, P = 0.013) and lower postoperative albumin (OR 0.946, P = 0.018). Pulmonary imaging abnormalities [OR 19.862 (95% CI 2.546–154.936, P = 0.004)] was a novel independent predictors of postoperative pneumonia. Postoperative hypoalbuminemia has a higher incidence with the increase of operation time, and may be associated with postoperative complications in patients undergoing brain tumor surgery.

Hypoalbuminemia as Surrogate and Culprit of Infections

Hypoalbuminemia is associated with the acquisition and severity of infectious diseases, and intact innate and adaptive immune responses depend on albumin. Albumin oxidation and breakdown affect interactions with bioactive lipid mediators that play important roles in antimicrobial defense and repair. There is bio-mechanistic plausibility for a causal link between hypoalbuminemia and increased risks of primary and secondary infections. Serum albumin levels have prognostic value for complications in viral, bacterial and fungal infections, and for infectious complications of non-infective chronic conditions. Hypoalbuminemia predicts the development of healthcare-associated infections, particularly with Clostridium difficile. In coronavirus disease 2019, hypoalbuminemia correlates with viral load and degree of acute lung injury and organ dysfunction. Non-oncotic properties of albumin affect the pharmacokinetics and pharmacodynamics of antimicrobials. Low serum albumin is associated with inadequate antimicrobial treatment. Infusion of human albumin solution (HAS) supplements endogenous albumin in patients with cirrhosis of the liver and effectively supported antimicrobial therapy in randomized controlled trials (RCTs). Evidence of the beneficial effects of HAS on infections in hypoalbuminemic patients without cirrhosis is largely observational. Prospective RCTs are underway and, if hypotheses are confirmed, could lead to changes in clinical practice for the management of hypoalbuminemic patients with infections or at risk of infectious complications.

Can Fried Frailty Score predict postoperative morbidity and mortality in gynecologic cancer surgery? Results of a prospective study

BACKGROUND

Aim of this study is to evaluate the predictive ability of Fried Frailty Score for surgical outcomes in patients undergoing gynecologic cancer surgery.

METHODS

This is a prospective cohort study at an academic gynecological cancer center from Oct 2015 through Jan 2017. We applied systematically numerous screening tools, geriatric questionnaires and single measurements which may provide predictions for surgical outcomes. We classified frailty according to the Fried definition and surgical complications were graded according Clavien-Dindo criteria. Using logistic regression analysis, we identified predictive clinical variables for postoperative complications (POC).

RESULTS

Overall 226 patients were enrolled (median age 59 years, range 18-87 years). The prevalence of frailty based on the presence of three or more frailty criteria was 14.2%, the presence of one or two frailty criteria was classified as prefrail with 59.4% and without any presence as robust with 26.5%. Within 30 days of surgery, nine (3.8%) patients have died and 40 (18.3%) experienced a grade ≥ IIIb complication. In the regression analysis obesity (OR: 5.37, 95% CI 1.99-14.49, p = 0.001) as well as ECOG >1 (OR: 4.32, 95% CI 1.28-1.55, p = 0.018) and Albumin<3.6 g/dl (OR: 3.88, 95% CI 1.37-10.98, p = 0.011) emerged as significant predictors of postoperative complications (POC). Fried Frailty Score (OR: 2.41, 95% CI 0.91-6.41, p = 0.077) showed no significant additional predictive value.

CONCLUSION

Fried Frailty Score could help the surgeon to estimate the risk for POC among patients undergoing gynecologic cancer surgery. But preoperatively determined ECOG, BMI and Albumin can predict severe POC in patients undergoing gynecologic surgery more precisely and should be assessed routinely.

Risk Factors for Early Port Infections in Adult Oncologic Patients

PURPOSE

The purpose of this study was to retrospectively investigate risk factors for chest port (port) infections within 30 days of placement (early port infections) in adult oncologic patients.

MATERIALS AND METHODS

This single-institution, three-center retrospective study identified 1,714 patients (868 males, 846 females; median age 60.0 years old) who underwent port placement between January 2013 and August 2017. All patients received an intravenous antibiotic prior to port placement. The median absolute neutrophil count was 5,260 cells/μL, the median white blood cell (WBC) count was 7,700 cells/μL, and the median serum albumin was 4.00 g/dL at the time of port placement. Double-lumen ports were most commonly implanted (74.85%) more frequently in an outpatient setting (72.69%). Risk factors for early port infections were elucidated using univariate and multivariate proportional subdistribution hazard regression analyses.

RESULTS

A total of 20 patients (1.2%) had early port infections; 15 patients (0.9%) had positive blood cultures. The mean time to infection was 20 days (range, 9-30 days). The port-related 30-day mortality rate was 0.2% (4 of 1,714 patients). Most bloodstream infections were attributed to Staphylococcus spp. (n = 11). In multivariate analysis, hematologic malignancy (hazard ratio [HR], 2.61; 95% confidence interval (CI), 1.15-5.92.; P = .02), hypoalbuminemia (albumin <3.5 g/dL; HR, 3.52; 95% CI: 1.48-8.36; P = .004), leukopenia (WBC <3,500 cells/μL; HR, 3.00; 95% CI: 1.11-8.09; P = .03), and diabetes mellitus (HR, 3.71; 95% CI: 1.57-8.83) remained statistically significant risk factors for early port infection.

CONCLUSIONS

Hematologic malignancy, hypoalbuminemia, leukopenia, and diabetes mellitus at the time of port placement were independent risk factors for early port infections.

Risk Factors for Postoperative Complications After Vulvar Surgery

BACKGROUND/AIM

Although the trends of surgical treatment in vulvar cancer patients are towards less extended resections, a significant number of cases are still diagnosed with locally advanced diseases imposing performing extended resections. The aim of this paper is to identify the prognostic factors for the development of early postoperative complications following vulvar surgery.

PATIENTS AND METHODS

Between 2017 and 2019, 145 patients with vulvar cancer were submitted to surgery with a curative intent.

RESULTS

Among these cases there were 93 cases diagnosed with early stages of the disease and 52 cases diagnosed with advanced stages. The risk of postoperative complications was significantly influenced by: i) the stage of the disease, ii) the preoperative levels of serum albumin, iii) the status of the resection margins, iv) previous history of irradiation, v) length of hospital stay and vi) association of comorbidities.

CONCLUSION

Vulvar cancer surgery for locally advanced disease is still associated with high rates of postoperative complications, and an attentive selection of cases submitted to surgery is mandatory.

Pre-operative hypoalbuminemia is associated with complication rate and overall survival in patients with vulvar cancer undergoing surgery

OBJECTIVE

Hypoalbuminemia, a known marker for malnutrition, has been associated with an increased risk for perioperative morbidity and poor prognosis in patients with solid tumors. The aim of this study was to investigate the prognostic and predictive value of pre-treatment serum albumin levels for survival and postoperative complications in patients with vulvar cancer undergoing surgery.

METHODS

Within in this retrospective study, we assessed data of 103 consecutive patients with vulvar cancer undergoing primary surgery into this study. Pre-treatment serum albumin levels were correlated with clinico-pathological parameters and complications. We performed univariate log-rank test and multivariable Cox regression models to evaluate the association between pre-treatment serum albumin and survival.

RESULTS

We found hypoalbuminemia (< 35 mg/dl) in 9 of 103 (8.7%) patients. No difference in tumor characteristics was observed between patients with hypoalbuminemia and normal serum albumin levels. Difference in postoperative complications (55.6% and 37.8% of patients with hypoalbuminemia and normal serum albumin levels, respectively) was not statistically significant (p = 0.345). Shorter overall survival (OS) was observed in patients with hypoalbuminemia (5-year OS rate 17.1%) when compared to patients with normal serum albumin levels (5-year OS rate 58.6%, p = 0.004). In multivariable analysis, age (p = 0.017), FIGO stage (p = 0.011) and serum albumin levels (p = 0.013) were independently associated with OS.

CONCLUSION

Pre-treatment hypoalbuminemia is an independent prognostic biomarker for OS in patients with vulvar cancer. We did not find an association between pre-treatment hypoalbuminemia and a higher risk for postoperative complications.

Preoperative malnutrition with mild hypoalbuminemia associated with postoperative mortality and morbidity of colorectal cancer: a propensity score matching study

BACKGROUND

Malnutrition with hypoalbuminemia (albumin < 35 g/L) is an important factor in predicting risks associated with colorectal cancer surgery. However, there is limited data about the effects of mild hypoalbuminemia with small decreases in albumin on postoperative complications.

METHODS

This is a retrospective study using the multi-institutional, nationally validated database of the American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) to investigate mild hypoalbuminemia and its association with postoperative mortality and morbidity by using a propensity score matching method.

RESULTS

In a group of 30,676 colorectal cancer patients who received surgery, 5230 had mild hypoalbuminemia (< 35 and > =30 g/L) and 21,310 had normal albumin levels (> = 35 g/L). Significant differences were noted in 21 clinical characteristics between the two groups. After 1:2 propensity score matching postoperative mortality was significantly associated with mild hypoalbuminemia (OR = 1.74; p < 0.001). There were significant associations between mild hypoalbuminemia and 11 postoperative morbidities including deep vein thrombosis, pulmonary embolism, superficial and deep surgical site infection, pneumonia, septic shock, ventilator> 48 h, blood transfusion, return to operating room, stroke and re-intubation. Mild hypoalbuminemia was also associated with overall complication (B = 0.064, p < 0.001) and length of total hospital stay (B = 2.236, p < 0.001).

CONCLUSIONS

In colorectal cancer, this is the first propensity score matching study of malnutrition with mild hypoalbuminemia which demonstrates that a mild decrease in serum albumin contributes significantly to poor postoperative outcome.

Evidence-based wound classification for vulvar surgery: Implications for risk adjustment

OBJECTIVES

The correct wound classification for vulvar procedures (VP) is ambiguous according to current definitions, and infection rates are poorly described. We aimed to analyze rates of surgical site infection (SSI) in women who underwent VP to correctly categorize wound classification.

METHODS

Patients who underwent VP for dysplasia or carcinoma were collected from the National Surgical Quality Improvement Program database (NSQIP). SSI rates of vulvar cases were compared to patients who underwent abdominal hysterectomy via laparotomy, stratified by the National Academy of Sciences wound classification. Descriptive analyses and trend tests of categorical variables were performed.

RESULTS

Between 2008 and 2016, 2116 and 31,506 patients underwent a VP or TAH, respectively. Among VP, 1345 (63.6%), 364 (17.2%), and 407 (19.2%) women underwent simple vulvectomy, radical vulvectomy, or radical vulvectomy with lymphadenectomy, respectively. The overall rate of SSI for VP was higher than that observed for TAH (5.6% vs. 3.8%; p < 0.0001). While patients undergoing TAH displayed a corresponding increase in the rate of SSI with wound type (type I: 3.4%; type II: 3.8%, type III: 6.8%; type IV 10.6%; p < 0.001), no such correlation was observed for simple VP (type I: 3.3%, type II: 3.0%; type III: 3.2%; type IV: 0%; p = 0.40). On the other hand, a non-significant correlation was observed for radical VP (type I: 4.0%, type II: 10.1%; type III: 14.3%; type IV: 20.0%; p = 0.08). The overall rate of SSI in patients undergoing any radical VP was similar to patients undergoing hysterectomy with a type IV wound (10.1% vs 10.6%, p = 0.87).

CONCLUSION

Patients undergoing VP are at high risk of infection. Simple vulvectomy should be classified as a type II and radical vulvectomy as a type III wound. These recommendations are important for proper risk adjustment.

Early post-operative serum albumin level predicts survival after curative nephrectomy for kidney cancer: a retrospective study

BACKGROUND

Previous studies have shown that albumin-related systemic inflammation is associated with the long-term prognosis of cancer, but the clinical significance of an early (≤ 7 days) post-operative serum albumin level has not been well-documented as a prognostic factor in patients with renal cell cancer.

METHODS

We retrospectively included patients hospitalized for kidney cancer from January 2009 to May 2014. First, the receiver operating characteristic analysis was used to define the best cut-off of an early post-operative serum albumin level in determining the prognosis, from which survival analysis was performed.

RESULTS

A total of 329 patients were included. The median duration of follow-up was 54.8 months. Patients with an early post-operative serum albumin level < 32 g/L had a significantly shorter median recurrence-free survival (RFS; 49.1 versus 56.5 months, P = 0.001) and median overall survival (OS; 52.2 versus 57.0 months, P = 0.049) than patients with an early post-operative serum albumin level ≥ 32 g/L. After adjusting for age, BMI, tumor stage, post-operative hemoglobin concentration, and pre-operative albumin, globulin, and hemoglobin levels, multivariate Cox regression showed that an early post-operative serum albumin level < 32 g/L was an independent prognostic factor associated with a decreased RFS (HR = 3.60; 95% CI,1.05-12.42 [months], P = 0.042) and decreased OS (HR = 9.95; 95% CI, 1.81-54.80 [months], P = 0.008).

CONCLUSION

An early post-operative serum albumin level < 32 g/L is an independent prognostic factor leading to an unfavorable RFS and OS. Prospective trials and further studies involving additional patients are warranted.

Risk factors for cytomegalovirus disease with cytomegalovirus re-activation in patients with rheumatic disease

Objective: To assess risk factors for cytomegalovirus (CMV) disease with CMV re-activation in patients with rheumatic disease.Methods: The clinical data of consecutive patients with rheumatic disease who experienced CMV re-activation were examined. We evaluated the difference in various baseline factors at the first detection of CMV pp65 antigenemia on the development of CMV disease using logistic regression models. The changes of laboratory data in the 4 weeks before CMV re-activation were also assessed.Results: We identified 80 patients (median age [interquartile range] = 65.0 years [51.5-74.0]) with CMV re-activation. Oral candidiasis, serum albumin ≤30 g/L, and CMV pp65-positive cell count >5.6/10⁵ polymorphonuclear leukocyte cells were found to be associated with CMV disease (odds ratio [OR] [95% CI] = 9.99 [2.02-49.50], 11.4 [1.94-67.40] and 6.80 [1.63-28.30], respectively). Moreover, decreases in serum albumin level and blood lymphocyte count in the 4 weeks before CMV re-activation also predicted CMV disease (OR [95% CI] = 2.02 [1.07-3.8] and 1.96 [1.09-3.54], respectively).Conclusion: In CMV re-activation patients with rheumatic disease, the presence of oral candidiasis, high CMV pp65 positive cell count, and hypoalbuminemia are possible risk factors for CMV disease.
