Impact Of Preoperative Nutritional Status Research Articles

Evaluating the Impact of Preoperative Nutritional Status on Surgical Outcomes and Public Health Implications in General Surgery Patients.

Malnutrition is linked to more postoperative problems, a longer recovery period, and a higher death rate; preoperative nutritional condition is a critical factor in surgical outcomes. This study aimed to evaluate the impact of preoperative nutritional status on surgical outcomes in general surgery patients and explore its broader public health implications. A two-year observational research with 440 adult patients undergoing general surgery was carried out between January 2022 and December 2023. Based on preoperative nutritional tests, such as Nutritional Risk Screening (NRS-2002), Body Mass Index (BMI), and blood albumin levels, participants were divided into two groups: nutritionally sufficient and nutritionally compromised. Postoperative problems, such as infections, wound healing, duration of hospital stay, readmissions, and 30-day mortality, were examined in the data. Nutritionally compromised patients exhibited significantly worse outcomes, including higher rates of postoperative infections (80 out of 220, 36.36% vs. 30 out of 220, 13.64%), delayed wound healing (50 out of 220, 22.73% vs. 20 out of 220, 9.09%), longer hospital stays (9.87 ± 3.58 vs. 6.53 ± 2.31 days), increased readmission rates (40 out of 220, 18.18% vs. 10 out of 220, 4.55%), and higher 30-day mortality (25 out of 220, 11.36% vs. 5 out of 220, 2.27%) compared to the nutritionally adequate group. Long-term follow-up showed persistent differences in infection rates and wound healing, supporting the prolonged impact of poor nutritional status. Preoperative malnutrition significantly affects surgical outcomes, emphasizing the importance of nutritional optimization in preoperative care to enhance recovery and minimize complications.

Impact of preoperative nutritional status on morbidity and mortality in elderly patients undergoing subdural hematoma evacuation: the role of the Geriatric Nutritional Risk Index.

Nutritional status has been shown to impact patient outcomes across several neurosurgical procedures. However, few prior studies have assessed associations between preoperative nutritional status and outcomes in elderly patients undergoing subdural hematoma evacuations. The aim of this study was to identify associations between preoperative nutritional status and short-term outcomes in patients aged 65 years and older undergoing subdural hematoma evacuation. A retrospective cohort study was performed using the American College of Surgeons National Surgical Quality Improvement Program database. Geriatric patients (≥ 65 years of age) were categorized into three groups based on the Geriatric Nutritional Risk Index (GNRI): normal, malnourished, and severely malnourished. Patient demographic characteristics, comorbidities, and adverse events (AEs) were assessed. Multivariate logistic regression analyses were used to identify independent predictors of 30-day postoperative AEs, extended length of hospital stay (LOS), 30-day mortality, and nonroutine discharge. Of 2026 study patients, 908 (44.8%) had normal GNRI status, 564 (27.8%) had malnourished GNRI status, and 554 (27.3%) had severely malnourished GNRI status. The proportions of patients who experienced minor AEs (normal 12.7% vs malnourished 13.3% vs severely malnourished 19.0%, p = 0.003) and severe AEs (normal 25.3% vs malnourished 20.7% vs severely malnourished 35.7%, p ≤ 0.001) were greatest in the severely malnourished cohort. Mean LOS significantly increased along with increasing malnourishment (normal 9.1 ± 6.9 days vs malnourished 9.7 ± 7.0 days vs severely malnourished 11.3 ± 7.6 days, p ≤ 0.001), whereas the proportions of patients with 30-day mortality (normal 15.5% vs malnourished 15.6% vs severely malnourished 24.0%, p ≤ 0.001) and nonroutine discharge (normal 59.4% vs malnourished 66.1% vs severely malnourished 69.9%, p ≤ 0.001) similarly increased with increasing malnourishment. On multivariate analyses, severe malnourished status was significantly associated with increased odds of developing any AE (adjusted OR [aOR] 1.72, CI 1.33-2.23, p ≤ 0.001) and extended LOS (aOR 1.47, CI 1.11-1.95, p = 0.007), whereas malnourished status but not severely malnourished status was associated with increased odds of nonroutine discharge (aOR 1.46, CI 1.12-1.92, p = 0.006). Neither malnourished (p = 0.474) nor severely malnourished status (p = 0.367) was associated with increased odds of 30-day mortality. The authors' findings suggest that preoperative nutritional status may have implications for short-term outcomes after subdural hematoma evacuation in patients aged 65 years and older. Further studies are necessary to better optimize nutritional status perioperatively in this patient population.

The impact of preoperative nutritional status on postoperative outcomes: an insight from Geriatric Nutritional Risk Index in elderly pancreaticoduodenectomy patients

BackgroundMalnutrition is not uncommon among the elderly undergoing pancreatoduodenectomy (PD) and is related to increased complications. Previous studies have shown that the Geriatric Nutritional Risk Index (GNRI) predicts outcomes in various populations. Nevertheless, the research exploring the correlation between GNRI and postoperative outcomes in PD is scarce. This study aimed to investigate the preoperative malnutrition, as measured by GNRI, on outcomes in elderly patients undergoing PD.Materials and MethodsThis retrospective analysis enrolled 144 elderly patients underwent PD for periampullary tumors from November 2016 to December 2021. Patients were stratified based on the GNRI value: high/moderate nutrition risk (GNRI ≤ 92, N = 54), low nutrition risk (92 < GNRI ≤ 98, N = 35), and no nutrition risk (GNRI > 98, N = 55). Perioperative outcomes and postoperative surgical complications were compared between these groups. Univariate and multivariate analyses were performed on major postoperative complications and prolonged postoperative length of stay (PLOS).ResultsPatients in the high/moderate risk group were significantly older, with lower BMI (P = 0.012), higher mortality rate (11.1%, P = 0.024), longer PLOS (P < 0.001), and higher incidence of over grade IIIB complications (37.0%, P = 0.001), Univariate and multivariate analyses showed the high/moderate risk GNRI group (OR 3.61, P = 0.032), increased age (OR 1.11, P = 0.014) and operative time over 8 h (OR 3.04, P = 0.027) were significantly associated with increased major postoperative complications. The high/moderate risk GNRI group was also a significant predictor for prolonged PLOS (OR 3.91, P = 0.002).ConclusionsPreoperative GNRI has the potential to be a predictive tool for identifying high-risk elderly patients and monitoring nutritional status preoperatively to improve postoperative surgical outcomes following PD.

Clinical significance of the preoperative prognostic nutritional index on age/comorbidity burdens in patients with resectable non-small cell lung cancer.

Objective nutritional scoring systems using preoperative blood samples have shown the potential to predict the postoperative outcomes of patients with non-small cell lung cancer (NSCLC). However, it remains unclear whether the prognostic impact depends on age and comorbid burdens. We conducted this study to validate the impact of preoperative nutritional status, stratified with age and comorbidity. We reviewed the preoperative prognostic nutritional index (PNI) and postoperative outcomes of 713 consecutive patients with completely resected NSCLC. We identified the optimal cutoff values of the PNI as 46. Significantly higher postoperative complication rates and worse survival rates were observed in the low PNI (≤ 46) group, regardless of age/comorbidity burdens. Multivariate analysis showed that a low PNI (≤ 46) was an independent prognostic factor for poor overall survival (hazard ratio: 2.5). A matched-pair analysis gave consistent results, showing that a low PNI (≤ 46) was an independent prognostic factor for poor overall survival (OS; hazard ratio: 1.8) and recurrence-free survival (RFS; hazard ratio: 1.6). Nutritional status, indexed by the PNI, is a strong prognostic factor for the postoperative outcomes of patients undergoing curative resection for NSCL, regardless of age/comorbidity burdens.

P216 Oral Budesonide and low serum albumin levels at surgery are associated with a higher risk of postoperative intra-abdominal septic complications after primary ileocecal resection for Crohn’s disease: a retrospective analysis of 853 consecutive patients treated in a tertiary centre.

Abstract Background Patients undergoing ileocecal resection for Crohn’s disease (CD) are at high risk of postoperative intra-abdominal septic complications (IASC). The associated risk factors are still debated. The aim of the study was to identify the variables associated with IASC in patients treated for primary CD of the terminal ileum. Methods Retrospective single-centre study including consecutive patients undergoing ileocecal resection for CD between 2004-2021 and managed before surgery in a multidisciplinary IBD unit. Outcomes to identify the variables associated with IASC (primary aim) and severe complications, classified as Clavien-Dindo grade 3 and higher (secondary aim). The potential independent predictors of each outcome were evaluated using logistic regression. To reduce overfitting, all models were built including only the variables that were significant at univariate analyses, except for age, gender and history of cardiovascular diseases, that were included a priori. Standard diagnostic procedures were adopted to check all models validity: influential observation analysis (Dbeta, change in Pearson chi-square), Hosmer-Lemeshow test for the goodness of fit and C statistic (area under the Receiving Operator Curve). Results A total of 853 patients were included. Overall sample characteristics are shown in Table 1. Table 2 and Table 3 reported the comparison according to the primary (IASC) and secondary (severe complications) outcomes, respectively. Table 4 showed the multivariate analyses of the potential predictors of IASC and severe complications. The onset of IASC was associated with lower serum albumin level (OR 1.81, 95% CI 1.15-2.94, p=0.011) and the use of oral budesonide at time of surgery (OR 2.07, 95% CI 1.12-3.83, p= 0.021). The risk of severe complications was associated with a history of cardiovascular disease (OR 2.91, 95% CI 1.08-7.84, p=0.03) and lower serum albumin level (OR 1.58, 95% CI 1.02-2.50, p=0.04). Conclusion The present study analysed a large population of patients affected by CD of the terminal ileum who were treated homogeneously before surgery in a multidisciplinary setting and confirmed the significant impact of preoperative nutritional status on the risk of severe postoperative complications and IASC. The latter, however, was also associated with the use of oral budesonide at the time of surgery. This finding has not been previously reported in the literature. Based on the present evidence, oral budesonide should be discontinued or tapered to the lowest dose before surgery.

Impact of Preoperative Nutritional Status on Long-term Survival in Patients With Stage I-III Colorectal Cancer.

In addition to oncological and treatment factors, the outcomes of cancer treatment are greatly influenced by host factors, such as the nutritional status. The aim of this study was to evaluate the association between the preoperative nutritional status and the prognosis of colorectal cancer patients using three nutritional indices. The target cohort consisted of 529 patients with stage I-III colorectal cancer, who underwent curative surgery between January 2015 and December 2019. The nutritional indices were calculated according to the equations that follow. Prognostic nutritional index (PNI)=10×serum albumin concentration (g/dl) +0.005×peripheral lymphocyte count (/μl). Nutritional risk index (NRI)=15.19×serum albumin concentration (g/dl)+41.7×present weight/usual weight. Geriatric nutritional risk index (GNRI)=14.89×serum albumin concentration (g/dl)+41.7×present weight/ideal weight. Ideal weight was calculated as follows: height(cm)-100-[(height(cm)-150)/4] for men and height(cm)-100-[(height(cm)-150)/2.5] for women. In common with all nutritional indices (PNI, NRI and GNRI), the low-nutritional index group had significantly lower relapse-free and overall survival rates than the high-nutritional index group. Furthermore, a subgroup analysis according to the NRI showed the association of the NRI with the patient prognosis for each stage. The preoperative nutritional status may have a close relationship with the prognosis in patients who receive curative surgery for colorectal cancer.

Abstract 10250: Association of Nutritional Status With Symptoms and Quality of Life After Aortic Valve Replacement

Introduction: Most patients with aortic stenosis (AS) are elderly and have multiple comorbidities. These conditions are often associated with poor nutrition and frailty. The purpose of this study was to assess the impact of preoperative nutritional status on symptoms and quality of life (QOL) after aortic valve replacement. Methods: We prospectively studied 220 patients with severe AS. Nutritional status was assessed using the Mini Nutritional Assessment (MNA) questionnaire. A score below 24 out of 30 indicates risk of malnutrition. Patients were evaluated preoperatively and three months after intervention. QOL was assessed using the RAND 36-item health survey. The six-minute walking test (6MWT) and the five times sit to stand test (5TSTS) were performed in 92 and 87 patients, respectively. Results: MNA score was below 24 in 28 % of the patients. Age, BMI, sex, and the proportion of patients undergoing surgery or TAVI were similar between MNA &lt; 24 and MNA &gt; 24 groups. There were no differences in NYHA class preoperatively, however a larger proportion of patients with MNA &lt; 24 remained in NYHA 2 or higher after intervention (42 % vs 25 %, p = 0.03). They also remained more symptomatic, with dyspnea in 28 % vs 12 % (p = 0.01) and decreased exercise capacity in 44 % vs 16 % (p &lt; 0.001) of the patients. Postoperative QOL was worse in patients with MNA &lt; 24, with significant differences in seven categories (Figure). They performed worse in 6MWT at baseline (median 380 m vs 480 m, p = 0.02), but the difference was not significant after intervention (480 m vs 499 m, p = 0.4). Difference in 5TSTS was not significant at baseline (13.45 s vs 11 s, p = 0.1), but they performed worse after intervention (14.95 s vs 10.8 s, p = 0.02). Conclusions: Malnutrition is common among AS patients and is associated with worse QOL and more symptoms after intervention. Nutritional status should be assessed in AS patients before intervention for risk stratification and to find patients who might benefit from nutritional intervention.

Impact of Preoperative Nutritional Status on the Outcome of Catheter Ablation for Atrial Fibrillation.

The relationship between nutritional status and the incidence or prognosis of atrial fibrillation (AF) has been reported, but no studies have described the relationship between the outcomes of AF catheter ablation (CA) and nutritional status as assessed by various scoring tools. We aimed to verify the hypothesis that preoperative nutritional status is associated with arrhythmia recurrence after CA for AF. We evaluated 913 patients (age, 67±10 years; men, 72%; paroxysmal AF, 56%) who underwent CA for AF between November 2011 and November 2017. Patients were systematically followed with an endpoint of atrial tachyarrhythmia recurrence, the predictive value of which was compared among 3 scoring tools (Controlling Nutritional Status [CONUT] score / Geriatric Nutritional Risk Index [GNRI] / Prognostic Nutritional Index [PNI]). Patients were divided into normal nutrition (CONUT <2 [n=637] / GNRI >98 [n=836] / PNI >38 [n=910]) and undernutrition (CONUT ≥2 [n=276] / GNRI ≤98 [n=77] / PNI ≤3 [n=3]) groups. AF recurred in 274 patients (mean follow-up, 2.3±0.8 years). The AF recurrence rate was higher in patients with undernutrition than in those with normal nutrition (CONUT/GNRI) status. Multivariate Cox regression analysis identified undernutrition status (GNRI ≤98) as an independent predictor of atrial tachyarrhythmia recurrence. The AF recurrence rate after CA was higher in patients with undernutrition than in those with normal nutrition as stratified by the nutrition scoring tools.

Preoperative nutritional score predicts underlying liver status and surgical risk of hepatocellular carcinoma.

Given the scarce evidence regarding the impact of preoperative nutritional status on surgical outcomes of patients with hepatocellular carcinoma, predictive powers of nutritional/inflammatory scores for short-term surgical outcomes in patients with hepatocellular carcinoma were investigated. Outcomes of 1272 patients with hepatocellular carcinoma were reviewed, and predictive powers of nine nutritional/inflammatory scores for short-term surgical outcomes were compared using the receiver-operating characteristic curve analysis. Clinical relevance of the best nutritional score was then studied in detail to clarify its utility as an alternative predictive measure for surgical risk of patients with hepatocellular carcinoma. Receiver-operating characteristic curve analysis showed the controlling nutritional status score has the best performance in prediction of morbidity after hepatectomy for hepatocellular carcinoma (area under the curve, 0.593; 95% confidence interval: 0.552-0.635; p < 0.001), and multivariate analysis confirmed its correlation with the risk of any morbidity (odds ratio per +1 point, 1.17; 95% confidence interval: 1.08-1.27; p < 0.001) and major morbidity (odds ratio per +1 point, 1.14; 95% confidence interval: 0.99-1.27; p = 0.052). The undernutrition grade based on the controlling nutritional status score showed strong correlation with the degree of fibrosis in the liver (p < 0.001), platelet count (p < 0.001), and indocyanine green retention rate at 15 min (p < 0.001). In addition, the controlling nutritional status undernutrition grade well stratified the risk of postoperative morbidity especially in cirrhotic subpopulation (odds ratio, 1.17 per +1 point; 95% confidence interval: 1.05-1.29 for any morbidity and odds ratio, 1.20 per +1 point; 95% confidence interval: 1.03-1.40 for major morbidity). The controlling nutritional status score could be an alternative measure for underlying liver injury and the surgical risk of hepatocellular carcinoma.

The Impact of Preoperative Nutritional Status on the Survival of Patients With Esophageal Squamous Cell Carcinoma.

Background: The goal of this study was to investigate the impact of different nutritional parameters in patients with esophageal squamous cell carcinoma (ESCC) who underwent surgical resection.Methods: A total of 620 patients with ESCC who underwent esophagectomy were analyzed. A receiver operating characteristic curve was constructed to set the appropriate cutoff points for five nutritional parameters: serum albumin (SA), body mass index (BMI), geriatric nutritional risk index (GNRI), prognostic nutritional index (PNI), and a new modified nutritional risk index (mNRI). Survival analyses were performed to calculate overall survival and investigate the independent prognostic factors.Results: The median preoperative BMI, SA, GNRI, PNI, and mNRI values were 20.90, 42.75, 102.95, 51.90, and 63.90, respectively. The corresponding optimal cutoff points were 18.75 for BMI, 43.05 for SA, 98.5 for GNRI, 51.45 for PNI, and 61.45 for mNRI. All nutritional parameters were significantly correlated with tumor length and pT category. Decreased nutritional parameters were significantly correlated with poor survival in univariate analysis; however, only the mNRI was an independent prognostic factor in multivariate analysis (P = 0.041).Conclusions: Nutritional parameters are convenient and valuable prognostic factors in ESCC patients who undergo surgical resection. The new mNRI parameter may be superior to the other nutritional parameters.

The presurgical controlling nutritional status (CONUT) score is independently associated with severe peristomal skin disorders: a single-center retrospective cohort study

While nutritional interventions may potentially lower the risk of peristomal skin disorders (PSDs) and their exacerbation, no previous studies have evaluated the relationship between PSDs and nutritional status using the Controlling Nutritional Status (CONUT) score. The purpose of this study was to assess the impact of preoperative nutritional status on stoma health, and determine risk factors for postoperative PSDs, including severe PSDs. A retrospective analysis was performed of 116 consecutive patients with rectal cancer who underwent radical surgery with ileostomy or colostomy creation. PSDs were diagnosed in 32 patients (27.6%); including 10 cases (8.7%) that were defined as severe based on the ABCD-stoma score. Multivariable logistic regression showed that smoking (odds ratio [OR] 3.451, 95% confidence interval [CI] 1.240–9.607, p = 0.018) and ileostomy (OR 3.287, 95% CI 1.278–8.458, p = 0.014) were independent risk factors for PSDs. A separate multivariable logistic regression analysis of risk factors for severe PSDs, found that the only independent risk factor was the CONUT score (OR 10.040, 95% CI 1.191–84.651, p = 0.034). Severe PSDs are associated with preoperative nutritional disorders, as determined by the CONUT score. Furthermore, nutritional disorders may increase the severity of PSDs, regardless of the stoma type.

Preoperative malnutrition is a risk factor for delayed recovery of mobilization after total hip arthroplasty.

Many studies have examined nutritional status and deteriorated postoperative outcomes in patients undergoing total hip arthroplasty. However, few studies have focused on nutritional status and postoperative mobility. To investigate the impact of preoperative nutritional status on mobility after total hip arthroplasty. Retrospective single-institution cohort study. Orthopedic inpatient rehabilitation center. A total of 503 patients who underwent unilateral primary total hip arthroplasty from 2015 through 2019 were included. Data were collected on patient demographics, comorbidities, preoperative nutritional status, and quadriceps strength. Nutritional status was assessed using the Controlling Nutritional Status (CONUT) score. Not applicable. The primary outcome was postoperative mobility defined as the number of days from surgery to starting to walk independently. Among 503 patients undergoing total hip arthroplasty, 18.9% were classified as malnourished. Patients with malnutrition had a one-day delay in achieving mobilization compared with patients with normal nutrition (6 vs. 5 days, P=.006). According to the Kaplan-Meier curves, patients with malnutrition had a significant delay in mobilization compared with those with normal nutrition (P < .001). All three Cox proportional hazards regression models showed that preoperative malnutrition was associated with a higher risk of delayed mobilization (hazard ratios 0.70-0.74). Preoperative malnutrition as assessed by the CONUT is a significant risk factor for delayed recovery of mobilization after total hip arthroplasty.

Preoperative Body Weight and Albumin Predict Survival in Patients With Resectable Lung Neoplasms: Role of COPD

The impact of preoperative nutritional status on survival in lung cancer (LC) patients with underlying chronic obstructive pulmonary disease (COPD) is still unclear. We hypothesized that presurgical nutritional assessment may differentially predict mortality in patients with resectable LC with moderate COPD and relatively well-preserved nutritional status. Nutritional assessment [body mass index (BMI), blood parameters including albumin and protein levels, and body weight loss], and other clinical parameters [cigarette smoking (CS) history, LC staging and histological subtypes, COPD severity, lung function, and adjuvant therapy] were evaluated in 125 patients from the LC Mar Prospective Cohort: 87 LC-COPD patients and 38 LC patients without COPD before thoracotomy. Ten-year overall survival (OS) was analyzed in all patients. Prior to thoracotomy, in LC-COPD patients compared to LC, BMI and albumin declined relatively, low levels of the parameters BMI, albumin, and total proteins were associated with poorer 10-year survival, especially in the LC-COPD. CS burden also correlated with impaired survival. COPD per se worsened the prognosis in LC patients. In the present cohort of LC patients with resectable tumors and relatively well-preserved nutritional status, the parameters BMI and blood albumin and protein levels measured prior to thoracotomy predicted OS, especially in those with COPD. These are clinically relevant findings, since values of those nutritional parameters were within the normal ranges in the majority of the analyzed patients. A thorough nutritional preoperative assessment should be included in the study of patients with resectable LC, particularly in those with chronic airway obstruction. El impacto del estado nutricional preoperatorio en la supervivencia en pacientes con cáncer de pulmón (CP) y enfermedad pulmonar obstructiva crónica (EPOC) subyacente aún no está claro. Planteamos la hipótesis de que la evaluación nutricional prequirúrgica puede predecir diferencialmente la mortalidad en pacientes con CP resecable y EPOC moderada, y un estado nutricional relativamente bien conservado. Se evaluaron el estado nutricional (índice de masa corporal [IMC], parámetros sanguíneos que incluyeron los niveles de albúmina y proteínas y pérdida de peso corporal) y otros parámetros clínicos (antecedentes de tabaquismo, estadificación del CP y el subtipo histológico, gravedad de la EPOC, función pulmonar y terapia adyuvante) en 125 pacientes de la cohorte prospectiva de CP del Hospital del Mar: 87 pacientes con EPOC-CP y 38 pacientes con CP sin EPOC antes de la toracotomía. Se analizó la supervivencia global (SG) a 10 años en todos los pacientes. Antes de la toracotomía, en los pacientes con EPOC-CP, el IMC y la albúmina disminuyeron en comparación con los del grupo de CP; los niveles bajos de los parámetros IMC, albúmina y proteínas totales se asociaron con menor supervivencia a 10 años, especialmente en los EPOC-CP. La carga tabáquica también se correlacionó con una disminución en la supervivencia. La EPOC empeoró per se el pronóstico en pacientes con CP. En la presente cohorte de pacientes con CP resecable y estado nutricional relativamente bien conservado, el IMC y los niveles de albúmina y proteínas en sangre medidos antes de la toracotomía predijeron la SG, especialmente en aquellos con EPOC. Estos son hallazgos clínicamente relevantes, ya que los valores de esos parámetros nutricionales estaban dentro de los rangos normales en la mayoría de los pacientes analizados. Se debe incluir una evaluación nutricional preoperatoria exhaustiva en el estudio de pacientes con CP resecable, particularmente en aquellos con obstrucción pulmonar crónica.

Impact of preoperative nutritional status on surgical outcomes in patients with pediatric gastrointestinal surgery.

BackgroundMalnutrition has a high incidence among pediatric surgical patients and contributes to increased risks of postoperative complications and extended hospital stays.PurposeThe present study aimed to determine the influence of preoperative nutritional status on the postoperative outcomes of pediatric patients who underwent elective gastrointestinal (GI) surgery.MethodsThis prospective observational study was conducted at Cairo University Specialized Pediatric Hospital. According to the designated inclusion criteria, 75 surgical cases of both sexes were included. A structured questionnaire was developed and administered. This questionnaire included 3 main sections: demographic data and nutritional status parameters at admission and discharge. Pre- and postoperative nutritional statuses were compared.ResultsAccording to both the subjective global nutritional assessment and STRONGKIDS score Questioner, more than 60% of patients in the upper GI patient group were at risk of malnutrition. Wasting status was most common in the upper GI patient group (67%; vs. 39.1% in the lower GI group). Underweight status was more common in the hepatobiliary and upper GI patient groups (nearly 50% for each group) than in the lower GI group (30.4%). On the other hand, stunted patients had a higher incidence of complications and a prolonged hospital stay (P=0.003 and P=0.037, respectively), while underweight lower GI patients experienced a prolonged hospital stay (P=0.02). A higher proportion of patients with preoperative anemia than those without preoperative anemia required a blood transfusion (P=0.003).ConclusionNutritional assessment is a crucial component of pediatric surgical patient management. Both underweight and wasting statuses were more common among hepatobiliary and upper GI patients. Postoperative complications and a long hospital stay were more common among stunted patients.

Preoperative Body Weight and Albumin Predict Survival in Patients With Resectable Lung Neoplasms: Role of COPD

The impact of preoperative nutritional status on post-surgical complication and mortality rates in patients undergoing radical cystectomy for bladder cancer: a systematic review of the literature.

To investigate the impact of preoperative nutritional factors [body mass index (BMI)], hypoalbuminemia (< 3.5g/dL, sarcopenia) on complication and mortality rates after radical cystectomy (RC) for bladder cancer. The PubMed database was systematically searched for studies investigating the effect of nutritional status on postoperative outcomes after RC. English-language articles published between March 2010 and March 2020 were reviewed. For statistical analyses odds ratios (ORs) and hazard ratios (HRs) weighted mean was applied. Overall, 81 studies were included. Twenty-nine studies were enrolled in the final analyses. Patients with a 25-29.9kg/m2 BMI (OR 1.55, 95% confidence interval [CI] 1.14-2.07) and those with a BMI ≥ 30kg/m2 (OR 1.73, 95% CI 1.29-2.40) had a significantly increased risk of 30day complications after RC. Preoperative hypoalbuminemia increased the risk of 30day complications (OR 1.56, 95% CI 1.07-2.35); it was a predictor of worse 3year overall survival (OS) (HR 1.86, 95% CI 1.32-2.66). Sarcopenic patients had a higher risk of 90day complications than non-sarcopenic ones (OR 2.49, 95% CI 1.22-5.04). Sarcopenia was significantly associated with unfavorable 5year cancer-specific survival (CSS) (HR 1.73, 95% CI 1.07-2.80), and OS (HR 1.60, 95% CI 1.13-2.25). High BMI, hypoalbuminemia, and sarcopenia significantly increased the complication rate after RC. Hypoalbuminemia predicted worse 3year OS and sarcopenia predicted unfavorable 5year CSS and OS. Preoperative assessment of RC patients' nutritional status is a useful tool to predict perioperative and survival outcomes.

The Impact of Pre-operative Nutritional Status on Outcomes Following Congenital Heart Surgery.

Aims and Objectives: Malnutrition is common in children with congenital heart disease and may contribute to adverse outcomes. This study evaluates the impact of pre-operative nutritional status on outcomes after congenital heart surgery.Methods: We conducted a retrospective cohort study enrolling children under 10 years old who underwent congenital heart surgery at a tertiary children's hospital from 2012 to 2016. Patients who had patent ductus arteriosus ligation only, genetic syndromes, or global developmental delay were excluded. Outcome measures included 30-day mortality, intensive care unit (ICU) length of stay (LOS), hospital LOS, duration of mechanical ventilation, and number of inotropes used post-operatively. We performed univariate/multivariable logistic regression analysis, adjusting for age, cyanotic cardiac lesion, co-morbidity, and Risk Adjustment for Congenital Heart Surgery (RACHS-1) score.Results: Three hundred two children of median age 16.2 [interquartile range (IQR) 3.1, 51.4)] months were included. The most common cardiac lesions were ventricular septal defect (27.8%), atrial septal defect (17.9%), and Tetralogy of Fallot (16.6%). Median weight-for-age z-score (WAZ) was −1.46 (IQR −2.29, −0.61), height-for-age z-score (HAZ) was −0.94 (IQR −2.10, −0.10), and body mass index (BMI)-for-age z-score (BAZ) was −1.11 (IQR −2.19, −0.30). In multivariable analysis, there was an increased risk of 30-day mortality for WAZ ≤−2 vs. WAZ >−2 [adjusted odds ratio (aOR): 4.01, 95% CI: 1.22, 13.13; p = 0.022]. For HAZ ≤-2 vs. HAZ > −2, there was increased risk of hospital LOS ≥ 7 days (aOR: 2.08, 95% CI: 1.12, 3.89; p = 0.021), mechanical ventilation ≥48 h (aOR: 2.63, 95% CI: 1.32, 5.24; p = 0.006) and of requiring ≥3 inotropes post-operatively (aOR: 3.00, 95% CI: 1.37, 6.59; p = 0.006).Conclusion: In children undergoing congenital heart surgery, WAZ ≤ −2 is associated with higher 30-day mortality, while HAZ ≤ −2 is associated with longer durations of hospital LOS and mechanical ventilation, and increased risk of use of 3 or more inotropes post-operatively. Future studies are necessary to develop safe and efficacious peri-operative nutritional interventions, particularly in patients with WAZ and HAZ ≤ −2.

Impact of Preoperative Nutritional Status on the Incidence Rate of Surgical Complications in Patients With Inflammatory Bowel Disease With Vs Without Preoperative Biologic Therapy: A Case-Control Study.

OBJECTIVES:A case-control study was undertaken to assess the impact of preoperative nutrition on surgical outcomes in patients with inflammatory bowel disease with vs without preoperative biologic therapy.METHODS:Seventy patients who had received biologic therapy within 8 weeks before undergoing resection for active ulcerative colitis (n = 34) or Crohn's disease (n = 36) were included (BIO group). The control group comprised 70 patients without exposure to biologics, selected based on 5 matching criteria: inflammatory bowel disease subtype (ulcerative colitis/Crohn's disease), age (≤ or >40 years), disease severity (moderate/severe), surgical approach (open/laparoscopic), and main surgical procedure. Poor nutrition was defined as the presence of at least one of the following criteria: weight loss >10%–15% within 6 months, body mass index <18.5 kg/m2, Subjective Global Assessment Grade C, or serum albumin <30 g/L.RESULTS:The proportion of patients with preoperative poor nutrition was 43% in the BIO and 33% in the control groups (P = 0.22). The incidence of postoperative infectious complications (anastomotic leak, intra-abdominal abscess, enterocutaneous fistula, or wound infection) was 16% in the BIO and 14% in the control groups (P = 0.81). In the BIO group, poor nutrition significantly increased the risk of infectious complications (27% vs 8% without poor nutrition, P = 0.03). In addition, in the control group, the incidence of infectious complications was higher in patients with poor nutrition, but not significantly (22% vs 11%, P = 0.21).DISCUSSION:Poor nutrition increases the risk of infectious complications after surgery. The detrimental effects of poor nutrition on postsurgical infection may be enhanced in patients who have received biologic therapy preoperatively.

Preoperative Nutrition Status and Postoperative Outcomes in Patients Undergoing Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy.

Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is a complex surgery to treat peritoneal surface malignancy (PSM). PSM and gastrointestinal (GI) resection from CRS can lead to significant GI symptoms and malnutrition. There is limited research into the nutrition status of this patient group and the impact of malnutrition on morbidity. This study aims to determine if preoperative malnutrition, assessed using the Subjective Global Assessment (SGA), is associated with postoperative morbidity and increased length of stay (LOS) in patients undergoing CRS/HIPEC for PSM. This study prospectively assessed the nutritional status of patients undergoing CRS/HIPEC using a validated nutrition assessment tool. Preoperative clinical symptoms, Peritoneal Cancer Index (PCI), intraoperative blood transfusions, operative time, GI resections, postoperative morbidity, and LOS, as well as pre- and postoperative nutritional interventions, were recorded. The impact of preoperative nutritional status was assessed in relation to postoperative complications and hospital LOS. The study included 102 participants; 34 patients (33%) were classified as malnourished (SGA = B or C). Preoperative weight loss (15% vs. 74%; p ≤ 0.001) and the presence of clinical symptoms (18% vs. 47%; p = 0.002) were significantly higher in malnourished patients. While PCI, intraoperative blood transfusions, and GI resections were independent predictors of morbidity, malnutrition was significantly associated with infectious complications and LOS. For each grade of worsening malnutrition, LOS increased by an average of 7.65 days. Preoperative malnutrition is prevalent in patients undergoing CRS/HIPEC and postoperative morbidity is common. Malnutrition is linked to LOS and plays a role in postoperative outcomes such as infection. Clear pre- and postoperative nutrition pathways are needed to optimize nutrition support and postoperative recovery.
