Self-Determination, Optimism, Social Support, Knowledge, and Skills Have a Positive Influence on the Oral Intake of Long-Stay Acute Patients: A Qualitative Study

BACKGROUND

Although previous research has attempted to understand the barriers and enablers of oral intake in hospitalized patients, these studies have mainly focused on short-stay inpatients and lacked a theory-driven examination of the determinants that influence dietary behavior in the hospital.

OBJECTIVE

To explore and compare the factors influencing adequate and poor oral intake in long-stay acute patients (admitted >14 days).

DESIGN

A qualitative descriptive study with semistructured interviews.

PARTICIPANTS/SETTING

Twenty-one adult inpatients (13 men, 8 women) admitted to 2 medical and 2 surgical wards at a tertiary hospital in Brisbane, Australia, during 2022, stratified by the Subjective Global Assessment. Analysis performed Transcripts were initially deductively analyzed against the Theoretical Domains Framework, and a reflexive thematic approach was used to create overall themes.

RESULTS

Of the 21 included patients (median age = 68.0 years, IQR 34 years), 11 had adequate/improved intake and 10 poor/decreased intake. Six themes were identified to have influenced oral intake in long-stay patients: self-determination to eat; nutrition impact symptoms; foodservice characteristics and processes; nutrition-related knowledge and skills; social support; and optimism, emotions, and emotion regulation. Patients with adequate/improved oral intake were characterized by an autonomous motivation to eat. They had increased awareness about their nutritional status, knowledge, and skills about food for recovery, were more optimistic, and social support was an important enabler to eating. In contrast, patients with poor/decreased oral intake perceived nutrition impact symptoms and dislike of meals as the main barriers to eating in the hospital; however, they also expressed more negative emotions, reduced coping strategies, and decreased knowledge, skills, intrinsic motivation, and capabilities to eat. Social support was present but did not enable oral intake in this patient group.

CONCLUSIONS

This study provides novel insights into the factors that influenced oral intake in long-stay acute patients, highlighting the importance of patient-centered nutrition care, encompassing motivational interviewing techniques and collaboration from the multidisciplinary team to create a supportive environment that fosters autonomy and empowers patients to actively participate in their own nutrition and recovery.

Prevalence of Disease-Related Malnutrition and Micronutrients Deficit in Patients with Inflammatory Bowel Disease: A Multicentric Cross-Sectional Study by the GSMII (Inflammatory Bowel Disease Study Group)

BACKGROUND AND AIMS

Inflammatory bowel disease (IBD) patients might experience disease-related malnutrition (DRM), but prevalence and risk factors are not well defined. The primary aim of the study was to define the prevalence of DRM and micronutrient deficiency in IBD patients; the secondary aim was to assess variables related to DRM.

MATERIALS AND METHODS

A multicenter, cross-sectional study was performed including consecutive adult IBD patients during a period of 2 weeks. Nutritional status was assessed with the body mass index (BMI) and the Malnutrition Universal Screening Tool. DRM was defined according to European Society for Clinical Nutrition and Metabolism guidelines.

RESULTS

Among the 295 enrolled patients, the prevalence of DRM was 23%, with no statistical difference between Crohn's disease and ulcerative colitis. Compared with well-nourished patients, patients with DRM showed higher rate of hospitalization in the previous month, were more often receiving systemic steroids, and had lower hemoglobin, albumin, and prealbumin levels and higher median C-reactive protein levels. At univariate logistic regression, current hospitalization, hospitalization in the previous month, low serum albumin, low BMI, high C-reactive protein, high Crohn's Disease Activity Index, and female sex were variables related to DRM. At the multivariate logistic regression, low BMI, current hospitalization and hospitalization in the previous month were significantly associated with DRM. In 23% of IBD patients, a deficiency of at least 1 micronutrient was observed, with no difference between ulcerative colitis and Crohn's disease.

CONCLUSIONS

DRM and microelements malnutrition are frequent conditions in the IBD population. DRM seems to be associated with disease activity and hospitalization.

Perioperative nutritional status thought to be important, but poorly understood

OBJECTIVES

Malnutrition has been shown to increase complications and leads to poor outcomes in surgical patients, but it has not been studied extensively in orthopedic trauma. This study's purpose is to determine the perspective and assessment of nutrition by orthopedic traumatologists.

METHODS

A survey was created and distributed via REDCap to orthopedic traumatologists at 60 U.S. trauma centers. Out of 183 distributed surveys, 130 surgeons completed the survey (71%). The survey focused on the importance of nutrition and practice patterns in orthopedic trauma.

RESULTS

Seventy-five percent of surgeons thought that nutritional status was "very important" to the final outcome of patients with orthopedic trauma injuries, 24% responded "somewhat important" and 1% responded "not important." Furthermore, 88% perform nutritional assessments; most surgeons (77%) utilize nutritional laboratory markers, with the most common markers being albumin, pre-albumin, transferrin and CRP. Additionally, 42% think trending the laboratory markers is important, and 50% are not sure if nutrition markers should be tested at multiple time points. Despite 75% of surgeons believing that nutrition is very important, only 8% discuss it with patients routinely. When asked what is more important for outcomes, nutrition or Vitamin D, almost three times as many surgeons thought nutrition was more important (29% vs 11%, respectively).

CONCLUSIONS

While orthopedic traumatologists believe nutrition is an important determinant of patient outcomes, this study shows a clear lack of consensus and variability in practice regarding nutrition among surgeons. Orthopedic trauma surgeons need specific guidelines on how to assess and treat malnutrition in trauma patients.

Guidance for assessment of the inflammation etiologic criterion for the GLIM diagnosis of malnutrition: A modified Delphi approach

BACKGROUND & AIMS

The Global Leadership Initiative on Malnutrition (GLIM) approach to malnutrition diagnosis is based on assessment of three phenotypic (weight loss, low body mass index, and reduced skeletal muscle mass) and two etiologic (reduced food intake/assimilation and disease burden/inflammation) criteria, with diagnosis confirmed by fulfillment of any combination of at least one phenotypic and at least one etiologic criterion. The original GLIM description provided limited guidance regarding assessment of inflammation and this has been a factor impeding further implementation of the GLIM criteria. We now seek to provide practical guidance for assessment of inflammation in support of the etiologic criterion for inflammation.

METHODS

A GLIM-constituted working group with 36 participants developed consensus-based guidance through a modified-Delphi review. A multi-round review and revision process served to develop seven guidance statements.

RESULTS

The final round of review was highly favorable with 99 % overall "agree" or "strongly agree" responses. The presence of acute or chronic disease, infection or injury that is usually associated with inflammatory activity may be used to fulfill the GLIM disease burden/inflammation criterion, without the need for laboratory confirmation. However, we recommend that recognition of underlying medical conditions commonly associated with inflammation be supported by C-reactive protein (CRP) measurements when the contribution of inflammatory components is uncertain. Interpretation of CRP requires that consideration be given to the method, reference values, and units (mg/dL or mg/L) for the clinical laboratory that is being used.

CONCLUSION

Confirmation of inflammation should be guided by clinical judgement based upon underlying diagnosis or condition, clinical signs, or CRP.

Association between being at-risk of malnutrition and discontinued home medical care among older patients: a 1-year follow-up study

BACKGROUND

Both malnutrition and at-risk of malnutrition are prevalent among older patients receiving home medical care. Discontinuation of home medical care usually occurs when an older patient is admitted to a hospital or nursing home or dies. This study aimed to assess prospective associations between nutritional status and discontinuation of home medical care in older patients.

METHODS

Three hundred and thirty-three Japanese older patients receiving home-visit nursing care services were included in this study. Their nutritional status was assessed using the Mini Nutritional Assessment®-Short Form, and patients were classified into three groups (well-nourished, at-risk of malnutrition and malnourished). Outcomes were confirmed at the 1-year follow-up survey. Hazard ratios (HRs) and 95% confidence intervals (CIs) for discontinuation of home medical care based on nutritional status were calculated using a Cox proportional hazard model. Covariates included age, sex, living status, economic status, activities of daily living, comorbidities and dysphagia status.

RESULTS

In total, 297 patients (median age: 84 years) were analysed. At baseline, 48.5% of the patients were at-risk of malnutrition and 18.9% were malnourished. During the observation period of 1 year, 27.6% patients discontinued their home medical care. In the adjusted model, the HR for discontinuation of home medical care among those at-risk of malnutrition was 2.44 (95% CI: 1.34-4.45) times than that of the well-nourished group, although the malnourished group was not significantly associated with discontinuation of home medical care (HR: 1.69, 95% CI: 0.77-3.72; referent: well-nourished).

CONCLUSIONS

At-risk of malnutrition was associated with discontinuation of home medical care among older patients.

CONCLUSION

Confirmation of inflammation should be guided by clinical judgment based on underlying diagnosis or condition, clinical signs, or CRP.

A scoping review on nutritional intake and nutritional status in people with a major dysvascular lower limb amputation

PURPOSE

To systematically review literature on nutritional intake, nutritional status and nutritional interventions, and to study their association with short- and long-term clinical outcomes in people with a major dysvascular lower limb amputation.

METHODS

PubMed, Ovid, CINAHL, and The Cochrane Library were searched. Studies were included if nutritional intake, nutritional status, or nutritional interventions in people with a major dysvascular lower limb amputation were analyzed.

RESULTS

Of the 3038 unique papers identified, 30 studies were included. Methodological quality was moderate (1 study) or weak (29 studies). Limited information was available on nutritional intake (2 studies) and nutritional interventions (1 study). Nutritional intake and nutritional status were assessed by diverse methods. The percentage of people with a poor nutritional status ranged from 1% to 100%. In some studies, measures of poor nutritional status were associated with adverse short- and long-term clinical outcomes.

CONCLUSIONS

The percentage of people with a poor nutritional status is inconclusive in the major dysvascular lower limb amputation population, because of the heterogeneity of the assessment methods used. Some included studies reported a negative association between poor nutritional status and clinical outcomes. However, these results should be interpreted with caution, because of the limited quality of the studies available. Studies high in methodological quality and high in hierarchy of evidence are needed.IMPLICATIONS FOR REHABILITATIONThe proportion of people with a poor nutritional status in the major dysvascular lower limb amputation population is inconclusive.Poor nutritional status seems to affect clinical outcomes negatively.More uniformity in assessment of malnutrition in the major dysvascular lower limb amputation population is needed.

Prealbumin level is a predictor of activities of daily living at discharge in older patients with heart failure who became ADL-independent after hospitalization: - Acute and early recovery cardiac rehabilitation trials

Chiba T, Yokota J, Takahashi R, Sasaki K, Suzuki H. Prealbumin level is a predictor of activities of daily living at discharge in older patients with heart failure who became ADL-independent after hospitalization - Acute and early recovery cardiac rehabilitation trials. Jpn J Compr Rehabil Sci 2023; 14: 69-77.

Objective

To determine the relationship between prealbumin level and activities of daily living (ADL) at discharge in patients with heart failure (HF) and assess the usefulness of prealbumin measurement in predicting discharge Barthel Index (BI) in older patients with HF who become non-independent in ADL after hospital admission.

Methods

Patients with HF, aged ≥75 years, who were admitted to an acute hospital and underwent acute and early recovery cardiac rehabilitation (CR) were studied retrospectively. The exclusion criteria were non-independent ADL before admission (BI < 85 points) and independent ADL at the start of CR (BI ≥ 85 points). The usefulness of prealbumin level in predicting discharge BI was compared between four models. Albumin and Controlling Nutritional Status (CONUT) were used as comparison variables. The models and independent variables were model 1 (covariates only), model 2 (prealbumin + covariates), model 3 (albumin + covariates), and model 4 (CONUT score + covariates). Adjusted R2, a measure of model fit, was used to compare predictive ability.

Results

A total of 152 patients were included in the analysis. Prealbumin level was a significant variable for BI at discharge but not albumin or CONUT. The adjusted R2 was higher in model 2 with the addition of prealbumin than that in model 1 (0.362 vs. 0.347).

Conclusion

Prealbumin levels are useful in predicting discharge BI in older patients with HF who become non-independent in ADL after hospitalization.

Reducing In-Hospital and 60-Day Mortality in Critically Ill Patients after Surgery with Strict Nutritional Supplementation: A Prospective, Single-Labeled, Randomized Controlled Trial

Malnutrition in critically ill patients is a global concern, especially those who undergo abdominal surgery, as it is associated to higher infectious complications, prolonged hospital stays, and increased morbidity. Despite the importance of proper nutrition, guidelines remain broad, and practical implementation is often inadequate. We aimed to assess the effects of strict nutritional provision and investigate the appropriate target for nutrition support. A prospective, randomized controlled trial was conducted in critically ill patients admitted to intensive care units following abdominal surgery. The intervention group received targeted protein and calories, with consultation from a nutritional support team upon admission. In total, 181 patients in the intervention and 144 in the control group were analyzed. The intervention group demonstrated improved nutrition provision and subsequently better clinical outcomes, including a reduced 60-day mortality (4.4 versus 15.3, p = 0.001), postoperative complications (24.9 versus 47.2, p < 0.001), and in-hospital mortality (5 versus 17.4, p < 0.001). High modified nutrition risk in the critically ill scores [odds ratio (OR) = 2.658, 95% CI = 1.498-4.716] were associated with increased 60-day mortality, while active nutritional intervention (OR = 0.312, 95% CI = 0.111-0.873) was associated with lower mortality rates. Notably, the provision of targeted energy and protein alone did not exhibit a significant association with mortality outcomes.

Canadian Nutrition Society Dialogue on disease-related malnutrition: a commentary from the 2022 Food For Health Workshop

This commentary represents a dialogue on key aspects of disease-related malnutrition (DRM) from leaders and experts from academia, health across disciplines, and several countries across the world. The dialogue illuminates the problem of DRM, what impact it has on outcomes, nutrition care as a human right, and practice, implementation, and policy approaches to address DRM. The dialogue allowed the germination of an idea to register a commitment through the Canadian Nutrition Society and the Canadian Malnutrition Task Force in the UN/WHO Decade of Action on Nutrition to advance policy-based approaches for DRM. This commitment was successfully registered in October 2022 and is entitled CAN DReaM (Creating Alliances Nationally for Policy in Disease-Related Malnutrition). This commitment details five goals that will be pursued in the Decade of Action on Nutrition. The intent of this commentary is to record the proceedings of the workshop as a stepping stone to establishing a policy-based approach to DRM that is relevant in Canada and abroad.

Prevalence and Impact of Malnutrition in Hospitalizations Among Celiac Diseases: A Nationwide Analysis

BACKGROUND/AIMS

Celiac disease (CD) is a T-cell-mediated gluten sensitivity that results in villous atrophy in the small intestine, leading to chronic malabsorption. Patients with celiac disease are prone to malnutrition. We assessed the impact of malnutrition on in-hospital outcomes in patients with CD.

MATERIALS AND METHODS

Patients with a primary discharge diagnosis of CD between January 2016 and December 2019 were included in the National Inpatient Sample Database. Data were collected on patient demographics, hospital characteristics, the Charlson Comorbidity Index (CCI), and concomitant comorbidities. The association between malnutrition and outcomes, including mortality, deep vein thrombosis (DVT), pulmonary embolism (PE), sepsis, acute kidney injury (AKI), length of stay (LOS), and total hospitalization charges (THC), was analyzed using the multivariate regression model.

RESULTS

A total of 187310 patients with CD were included in the analysis. Patients with CD and malnutrition had a higher risk of mortality (adjusted odds ratio [aOR], 2.08; p<0.001), AKI (aOR=1.18, p=0.003), and DVT (aOR=1.53; p<0.001) compared to patients with CD without malnutrition. No significant difference was noted in the rates of sepsis and PE. Patients with malnutrition also had a prolonged LOS (2.89 days; p<0.001) and higher THC ($22252.18; p<0.001) compared to patients without malnutrition.

DISCUSSION

Patients with CD and malnutrition are at high risk of worse outcomes. Early identification of malnutrition in CD can help prevent morbidity and mortality. Even strict adherence to a gluten-free diet has been associated with malnutrition. Further studies identifying factors associated with malnutrition in CD and the impact of interventions to prevent and treat malnutrition are encouraged.

Application of creatinine height index in patients with trauma for the evaluation of psoas muscle mass: A clinical validation study

BACKGROUND

The creatinine height index (CHI) is an estimate of lean body mass. We hypothesize that a modified CHI estimate using serum creatinine (sCr) levels in patients with normal renal function when performed soon after injury would reflect preinjury protein nutrition status.

METHODS

The urine CHI (uCHI) was calculated using the 24-h urine sample. The serum-derived estimated CHI (sCHI) was calculated using the sCr on admission. Correlation between abdominal computed tomography images at specific lumbar vertebral levels and total body fat and muscle content was used for comparison as an independent measurement of nutrition status unlikely to be substantially altered by trauma.

RESULTS

A total of 45 patients were enrolled, all with a significant injury burden (median injury severity score [ISS] = 25; interquartile range, 17-35). The calculated sCHI on admission was 71.0% (SD = 26.9%) and likely underestimates the CHI when compared with uCHI (mean = 112.5%, SD = 32.6%). Stratifying by degree of stress demonstrated that in a group of 23 moderately and severely stressed patients, uCHI (mean = 112.7%, SD = 5.7%) and sCHI (mean = 60.8%, SD = 1.9%) were significantly different and without correlation (r = -0.26, P = 0.91). In patients without stress, there was a significant negative correlation between sCHI and psoas muscle area (r = -0.869, P = 0.03), and in patients with severe stress there was a significant positive correlation between uCHI and psoas muscle area (r = 0.733, P = 0.016).

CONCLUSION

The CHI calculated from the initial sCr is not an appropriate estimate of uCHI in critically ill trauma patients and is not a valid measure of psoas muscle mass in this setting.

Pathogenesis, diagnosis, and treatment of malnutrition in patients with chronic pancreatitis

Chronic pancreatitis (CP) is a persistent and progressive pancreatic inflammatory disease. Malnutrition is a common clinical manifestation in CP patients, which is mainly caused by pancreatic exocrine insufficiency but may also be related to pancreatic endocrine insufficiency and changes of living habit. At present, there is still a lack of gold standard for the diagnosis of malnutrition in patients with CP. Clinicians should comprehensively evaluate such patients through anthropometric parameters, test parameters, imaging diagnosis, pancreatic exocrine function detection, etc., detect malnutrition early, and take timely intervention measures, including improving diet and living habits, enteral/parenteral nutrition, pancreatic enzyme replacement therapy, acid suppressant adjuvant therapy, regulating intestinal flora, and administration of Chinese medicine. And endoscopic and surgical treatment should be used when necessary.

Incidence and criteria used in the diagnosis of hospital-acquired malnutrition in adults: a systematic review and pooled incidence analysis

Despite advances in identifying malnutrition at hospital admission, decline in nutritional status of well-nourished patients can be overlooked. The aim of this systematic review was to investigate the incidence of hospital-acquired malnutrition (HAM), diagnostic criteria and health-related outcomes. PubMed, CINAHL, Embase and Cochrane Library were searched up to July 2021. Studies were included if changes in nutritional status was assessed with a validated nutrition assessment tool in acute and subacute adult (≥18 yrs) hospitalised patients. A random-effects method was used to pool the incidence proportion of HAM in prospective studies. The certainty of evidence was appraised using the Grading of Recommendation Assessment, Development and Evaluation system. We identified 12 observational cohort studies (10 prospective and 2 retrospective), involving 35,324 participants from acute (9 studies) and subacute settings (3 studies). Retrospective studies reported a lower incidence of HAM (<1.4%) than prospective studies (acute: 9-38%; subacute: 0-7%). The pooled incidence of HAM in acute care was 25.9% (95% confidence interval (CI): 17.3-34.6). Diagnostic criteria varied, with use of different nutrition assessment tools and timeframes for assessment (retrospective studies: >14 days; prospective studies: ≥7 days). Nutritional decline is probably associated with longer length of stay and higher 6-month readmission (moderate certainty of evidence) and may be association with higher complications and infections (low certainty of evidence). The higher incidence of HAM in the acute setting, where nutritional assessments are conducted prospectively, highlights the need for consensus regarding diagnostic criteria and further studies to understand the impact of HAM.

Hospital change to mixed lipid emulsion from soybean oil-based lipid emulsion for parenteral nutrition in hospitalized and critically ill adults improves outcomes: a pre-post-comparative study

INTRODUCTION

Early data suggest use of a mixed lipid emulsion (LE) with a soybean oil reduction strategy in parenteral nutrition (PN) may improve clinical outcomes. Duke University Hospital made a full switch to a Soybean oil/MCT/Olive/Fish Oil lipid (4-OLE) from pure soybean oil-based LE (Intralipid, Baxter Inc) in May 2017. Since 4-OLE has limited evidence related to its effects on clinical outcome parameters in US hospitals, evidence for clinical benefits of switching to 4-OLE is needed. Therefore, we examined the clinical utility of a hospital-wide switch to 4-OLE and its effect on patient outcomes.

METHODS

We conducted a single-center retrospective cohort study among adult patients (> 18 years) requiring PN from 2016 to 2019. Our primary exposure was treatment period (1-year pre-4-OLE switch versus 2-year post). We used multivariable regression models to examine our primary outcomes, the association of treatment period with hospital length of stay (LOS), and secondary outcomes liver function, infections, and ICU LOS. Analyses were stratified into critically ill and entire adult cohort.

RESULTS

We identified 1200 adults hospitalized patients. 28% of PN patients (n = 341) were treated pre-4-OLE switch and 72% post-4-OLE (n = 859). In the adult cohort, 4-OLE was associated with shorter hospital LOS (IRR 0.97, 95% CI 0.95-0.99, p = 0.039). The ICU cohort included 447 subjects, of which 25% (n = 110) were treated pre-4-OLE switch and 75% (n = 337) were post-switch. ICU patients receiving 4-OLE were associated with shorter hospital LOS (IRR 0.91, 95% CI 0.87-0.93, p < 0.0001), as well as a shorter ICU LOS (IRR 0.90, 95% CI 0.82-0.99, p = 0.036). 4-OLE ICU patients also had a significantly lower delta total bilirubin (- 1.6, 95% CI - 2.8 to - 0.2, p = 0.021) and reduced urinary tract infection (UTI) rates (OR 0.50, 95% CI 0.26-0.96, p = 0.038). There were no associations in AST, ALT, or total bilirubin in ICU and all adult patients.

CONCLUSION

4-OLE was successfully implemented and reduced soybean oil LE exposure in a large academic hospital setting. The introduction of 4-OLE was associated with reduced LOS, UTI rates, and mitigated hepatic dysfunction in critically ill patients. Overall, these findings prove a switch to a soybean oil-LE sparing strategy using 4-OLE is feasible and safe and is associated with improved clinical outcomes in adult PN patients.

Disease-Related Malnutrition and Enteral Nutrition

There are many misconceptions surrounding the diagnosing and treatment of malnutrition and around feeding people with enteral nutrition (EN). Often the decisions made by clinicians are made from anecdote or guidelines that may be out of date or supported by low-quality evidence. In this article, we will discuss different aspects of diagnosing malnutrition and delve deeper into the science and evidence behind certain recommendations. Our goal is to better equip the reader with the most current data-supported recommendation, such as indications, contraindications, complications of EN, tube and ostomy complications, types and use of specialized enteral formulas, and home management.

Effect of hypoalbuminemia on short-term outcomes after colorectal cancer surgery: A propensity score matching analysis

Purpose

The purpose of our study was to investigate the effect of pre-operative hypoalbuminemia on the short-term outcomes after primary colorectal cancer (CRC) surgery.

Materials and methods

The retrospective study enrolled CRC patients who underwent primary surgery from January 2011 to December 2021 in a single teaching hospital. The short-term outcomes were compared between the hypoalbuminemia group and the normal group using propensity score matching (PSM). Univariate and multivariate logistic regression analyses were used for analyzing independent predictors of overall complications and major complications.

Results

A total of 7,072 patients from a single center were enrolled in this study. There were 1,078 (15.2%) patients in the pre-operative hypoalbuminemia group and 5,994 (84.8%) patients in the normal pre-operative albumin group. After 1:1 PSM, there were 1,028 patients in the hypoalbuminemia group and 1,028 patients in the normal group. No significant differences were found in baseline information between the two groups after PSM. In terms of short-term outcomes, the hypoalbuminemia group had a longer operation time (p = 0.003), greater volume of blood loss (p = 0.036), longer hospital stays (p < 0.01), higher proportion of overall complications (p = 0.003), major complications (p = 0.016), higher incidence of pneumonia and abdominal infection (p = 0.001) than the normal group after PSM. Furthermore, hypoalbuminemia was an independent predictor for overall complications (p = 0.008) and major complications (p = 0.016).

Conclusion

Pre-operative hypoalbuminemia increased overall complications and major complications after primary CRC surgery. Furthermore, hypoalbuminemia was an independent predictor for overall complications and major complications.

Nutritional status and out-of-hospital mortality in vascular surgery patients

Background

Malnutrition is often present in vascular surgery patient during hospital admission. The present evidence of the consequence malnutrition has on morbidity and mortality is limited.

Aim

The purpose of this study was to determine the effect of nutritional status on out-of-hospital mortality in vascular surgery patients.

Methods

An observational cohort study was performed, studying non-cardiac vascular surgery patients surviving hospital admission 18 years or older treated in Boston, Massachusetts, USA. The exposure of interest was nutritional status categorized as well nourished, at-risk for malnutrition, nonspecific malnutrition or protein-energy malnutrition. The all cause 90-day mortality following hospital discharge was the primary outcome. Adjusted odds ratios were estimated by multivariable logistic regression models.

Results

This cohort included 4432 patients comprised of 48% women and a mean age 61.7 years. After evaluation by a registered dietitian, 3819 patients were determined to be well nourished, 215 patients were at-risk for malnutrition, 351 had non-specific malnutrition and 47 patients had protein-energy malnutrition. After adjustment for age, sex, ethnicity, medical versus surgical Diagnosis Related Group type, Deyo-Charlson index, length of stay, and vascular Current Procedural Terminology code category, the 90-day post-discharge mortality odds ratio for patients with non-specific malnutrition OR 1.96 (95%CI 1.21, 3.17) and for protein-energy malnutrition OR 3.58 (95%CI 1.59, 8.06), all relative to patients without malnutrition.

Discussion

Nutritional status is a strong predictor of out-of-hospital mortality. This suggests that patient with vascular disease suffering from malnutrition could benefit from more intensified In-hospital and out-of-hospital dietary guidance and interventions.

Recommendations for nutritional assessment across clinical practice guidelines: A scoping review

BACKGROUND & AIMS

CPGs propose several methods and criteria to perform nutritional assessment, a key process to determine the type and severity of malnutrition, which generates variability in clinical practice and outcomes. The aim of the study was to describe the criteria considered by clinical practice guidelines (CPGs) for nutritional assessment.

METHODS

We performed a scoping review systematically searching in PubMed, Trip Database, Google Scholar, and Google, until November 5, 2021. We included all CPGs mentioning tools or criteria for nutritional assessment in adults from the general population or with any specific pathology or condition. Two authors independently reviewed and decided on study selection and data extraction.

RESULTS

We included 18 CPGs (12 elaborated in Europe). The CPGs recommended heterogeneous criteria for nutritional assessment: 16/18 CPGs included at least one body composition parameter (e.g., loss of muscle mass, loss of subcutaneous fat), 15/18 included history related to dietary intake, 15/18 included clinical history (e.g., weight loss), 10/18 included anthropometric measurement (e.g., low body mass index [BMI]), 11/18 included biochemical criteria (e.g., albumin, C-reactive protein), 8/18 included physical examination (e.g., fluid retention, sarcopenia, loss of subcutaneous fat), 8/18 included functional test (e.g., decreased handgrip strength), and 1/18 included catabolic state. Also, 9/18 CPGs mentioned a tool for nutritional assessment, the Subjective Global Assessment (SGA) the most common (8/18). None of the CPGs justified the inclusion of any of the tools or criteria they mentioned.

CONCLUSIONS

The CPGs mentioned heterogeneous criteria for nutritional assessment. The most commonly mentioned criteria were decreased food intake, loss of muscle mass, weight loss, and low BMI. The most mentioned tool was the SGA. None of the CPGs provided a clear rationale for using certain criteria or tools for nutritional assessment.

The Evaluation and Management of Macronutrient Deficiency Dermatoses

In industrialized countries, nutritional dermatoses are likely underdiagnosed and result in increased disease morbidity and utilization of hospital resources. These findings underscore the need for physicians to be able to correctly identify these deficiencies. Nutritional dermatoses may be split into micronutrient deficiencies and macronutrient deficiencies. This article is intended to serve as a supplement to a two-part review of micronutrient deficiency dermatoses and highlights cutaneous findings in patients with protein-energy malnutrition and essential fatty acid deficiency. This article reviews the evaluation, cutaneous manifestations, and management of macronutrient deficiencies.

Malnutrition and its relation with diabetic foot ulcer severity and outcome: a review

BACKGROUND

Malnutrition has a detrimental effect on wound healing; hence, it might influence the outcome in people with a diabetic foot ulcer (DFU).The aim of this manuscript is to overview studies that describe the prevalence of malnutrition in DFU patients and assess the relation between malnutrition, DFU severity, and outcome.

METHODS

A literature review was performed. Malnutrition had to be defined by anthropometry and/or validated screening and assessment tools.

RESULTS

Five papers were included: one RCT, three prospective cohort studies and one retrospective observational study. A substantial number of patients were at risk for malnutrition (49%-70%) or were malnourished (15%-62%). In one study, nutritional status was related to DFU severity. Three authors demonstrated a negative influence of malnutrition on outcome. Two studies examined the prevalence of malnutrition after six months, but did not detect a decline in malnutrition rates.

CONCLUSIONS

Despite a large heterogeneity, all papers indicated that malnutrition is highly prevalent among DFU patients. Notwithstanding the lack of unequivocal evidence, malnutrition might have a negative influence on DFU outcome. Therefore, clinicians should pay attention to the nutritional status of people with a DFU.Abbreviations: BMI: Body Mass Index; DFU: Diabetic Foot Ulcer; DM: Diabetes Mellitus; GNRI: Geriatric Nutritional Risk Index; HbA1c: Glycated Hemoglobin; IWGDF: International Working Group on the Diabetic Foot; LEA: Lower Extremity Amputation; MNA: Mini Nutritional Assessment; MNA-SF: Mini Nutritional Assessment-Short Form; MUST: Malnutrition Universal Screening Tool; NRS-2002: Nutritional Risk Screening-2002; PAD: Peripheral Arterial Disease; RCT: randomized controlled trial; SGA: Subjective Global Assessment.

Effect of Whey Proteins on Malnutrition and Extubating Time of Critically Ill COVID-19 Patients

The novel SARS-CoV-2 virus has led to a severe pandemic, starting from early 2020. Intensive care (ICU) management of the COVID-19 disease is difficult with high morbidity and mortality. Early nutritional support, especially with whey protein, seems to be crucial in this medical case. Thus, we aimed to assess the effects of an adequate nutritional protocol rich in whey protein on nutritional and inflammatory status, extubating time, and mortality of critically ill COVID-19 patients (CICP). Methods: A prospective single-center exploratory observational study was undertaken on 32 consecutive CICP admitted to the ICU of Santa Maria Hospital, Terni, Italy, and treated with whey protein-enriched formula. Patients’ demographics, nutritional status, indexes of inflammation, daily pre-albumin serum levels, duration of mechanical ventilation, and mortality were recorded. Results: Thirty-two patients were enrolled. Ninety-five percent of them showed a gradual reduction in C-reactive protein (CRP) values and increase in pre-albumin levels after the whey protein-enriched formula. Prealbumin levels were not correlated with a better nutritional status but with a shorter extubating time and better survival. Conclusions: An adequate administration of whey protein during COVID-19 patients’ ICU stays can provide fast achievement of protein targets, reducing the duration of mechanical ventilation, and improving inflammatory status and ICU survival. Further prospective and large-scale, controlled studies are needed to confirm these results.

Caloric adequacy of parenteral nutrition and its influence on the clinical outcome of hospitalised patients

Background: The adaptation of Parenteral Nutrition (PN) to actual energy requirements of hospitalised patients is essential, since excessive and insufficient nutritional intake have been associated with poor clinical outcomes. Aim: To evaluate the adaptation of prescribed PN to the estimated nutritional requirements using three predictive equations and the influence of excessive/insufficient nutrient intake on patient clinical outcomes (nutritional parameters, metabolic and infectious complications). Methods: Prospective, observational study in hospitalised patients nutritionally assessed. Data was collected the first and fifth/sixth day of PN with clinical (infection, length of hospital stay), biochemical (visceral proteins, cholesterol, glucose, triglycerides, lymphocytes, CRP) and anthropometric parameters (skin folds, height, weight). Theoretical requirements were calculated using Harris-Benedict (HB), Mifflin-St Jeor (MF) and 25 Kcal/Kg/day formulas. The HB formula was used to compare estimated and provided requirements. Results: A total of 94 patients (mean: 72 ± 13.7 years old) were included with initial mean weight and height of 69.2 Kg and 162.8 cm, respectively (mean BMI: 26.1 Kg/m²). No statistically significant differences were found between the actual (1620 Kcal/day) and estimated caloric mean calculated with HB (1643 Kcal/day) and MF (1628 Kcal/day). When comparing with the caloric estimation, 31.9% of patients were underfed, while 14.9% were overfed. Intergroup analysis demonstrated significant variations in albumin, prealbumin, glucose, cholesterol, triglycerides and MUAC, with a significant increase of hyperglycaemia (+37.86; p < 0.05) and hypertriglyceridemia (+63.10; p < 0.05), being higher in overfed patients. Conclusion: In our study, inadequate nutrient intake was associated with a higher degree of hyperglycaemia and hypertriglyceridemia, without positive impact on anthropometric parameters.

Key approaches to diagnosing malnutrition in adults

Nutrition assessment is used to describe nutrition status-related nutrition problems and their causes, one of which includes malnutrition. Four malnutrition diagnostic tools are currently in use today in adults: Subjective Global Assessment, the Mini Nutritional Assessment, the Academy of Nutrition and Dietetics/American Society for Parenteral and Enteral Nutrition malnutrition consensus characteristics, and the Global Leadership Initiative on Malnutrition criteria. The aim of this article is to provide sufficient background of these methodologies to assist clinicians in choosing their approach in diagnosing malnutrition. There is substantial overlap between the criteria included in these malnutrition diagnostic approaches. A desired goal is to identify a core data set in order to evaluate malnutrition prevalence globally and to assess the impact of nutrition interventions on nutrition and clinical outcomes.

Malnutrition in patients admitted to in-hospital cardiac rehabilitation: Clinical correlates and association with mortality

Malnutrition is highly prevalent among hospitalized patients; thus, an accurate identification of malnutrition could improve the outcome of these patients. The aim of the present paper was to apply multiple methods to evaluate the prevalence of malnutrition and clinical correlates in patients admitted to in-hospital cardiac rehabilitation.  We performed a prospective study of 426 patients admitted to in-hospital cardiac rehabilitation: 282 (66.2%) had undergone a major cardiac surgery and 144 (34.8%) had experienced heart failure. The albumin level and Mini Nutritional Assessment (MNA) scores were applied to evaluate the nutritional status of these patients. Serum albumin levels were < 3.5 g/dl in 147 (34.5%) patients, and MNA scores were < 24 in 179 (42.0%) patients. Patients with malnutrition or a risk of malnutrition had lower haemoglobin values, lower EuroQol scores and poorer functional status. Female gender, age, functional status and Cumulative Illness Rating Scale severity were predictors of malnutrition. Over a median follow-up of 47 months, MNA scores <24 were associated with higher mortality, even after correction for confounding variables. In conclusion, in patients admitted to in-hospital cardiac rehabilitation, malnutrition and risk of malnutrition frequently occur and are associated with poor functional status, higher clinical complication rates and long-term mortality.

Malnutrition in Burns: A prospective, single center study

The hypermetabolic response from burn injury is the highest of the critically ill patient population. When coupled with the hypermetabolic response, preexisting malnutrition may increase the hospital resources used. The goal of this study was to evaluate the rate of malnutrition in burn patients and the associated hospital resource utilization.We collected prospective data on burn patients ≥ 18 years with a burn ≥ 10% TBSA admitted to a regional burn center. Demographics, %TBSA, co-morbidities, length of stay (LOS) and standardized LOS (LOS/%TBSA) were evaluated on 49 patients. A multivariable regression model was constructed. Nutrition assessment was completed within 24-48 hours of admission including an SGA (Subjective Global Assessment) classification. SGA A (well-nourished) was compared to SGA B and C (malnourished). Fourteen patients (28.6%) in this study were malnourished. Malnourished patients were not statistically different with respect to median age (50 versus 39; p = 0.08] and BMI (22.9 versus 26.5; p = 0.08) compared to the well-nourished group. However, malnourished patients had significantly longer median LOS (21.0 versus 11.0 days, p = 0.01) and LOS/%TBSA (1.69 versus 0.83, p = 0.001) than the well-nourished group. Being malnourished was a significant independent predictor of above median LOS/%TBSA (p=0.027) with an odds ratio (OR) of 5.61 (95% C.I. 1.215-25.890).The rate of malnutrition is important given the high metabolic demands of these patients. Malnutrition increased the resource requirements via higher standardized LOS. This underscores the importance of completing SGA on admission to identify malnutrition early on to optimize nutrition intervention during the patients' hospital stay.

Nomogram for predicting swallowing recovery in patients after dysphagic stroke

BACKGROUND

To date, variables predicting the recovery of dysphagia in patients after dysphagic stroke have not been well defined. However, despite the difficulties in predicting and understanding the dysphagia recovery trajectory, its significance for stroke care cannot be understated. This study aims to identify the factors for functional swallowing recovery and develop nomograms that predict dysphagia recovery after stroke.

METHODS

The demographic, neurological, and swallowing characteristics were compared between patients who recovered from dysphagia and those who did not. Then, the factors with P <.1 through comparison were enrolled in the multivariable logistic regression analysis to build a prediction model. A nomogram was also built to provide a quantitative tool. Discrimination, calibration, and clinical usefulness of the prediction model were assessed by using the C index, calibration plot, and decision curve analysis.

RESULTS

Predictors in the early-phase (T7) prediction nomogram included age, Functional Oral Intake Scale (FOIS), National Institutes of Health Stroke Scale (NHISS), hemispheric stroke, and brainstem stroke on admission. In the middle phase (T14), predictors included age, FOIS, and NHISS on admission. In the late phase (T30), predictors included age, FOIS, NHISS, bilateral stroke, and body mass index on admission. The C index for the day 7, day 14, and day 30 prediction nomograms were 0.847 (95% CI, 0.804-0.884), 0.817 (95% CI, 0.772-0.857), and 0.786 (95% CI, 0.739-0.829).

CONCLUSION

These novel nomograms predicting dysphagia recovery after ischemic stroke are discriminative and well calibrated and could be used to guide enteral nutrition decision making, rehabilitation plans, and individualized care.

Nutritional Assessment in Older Adults : MNA® 25 years of a Screening Tool and a Reference Standard for Care and Research; What Next?

A tool to assess nutritional status in older persons was really needed. It took 5 years to design the MNA® (Mini Nutrition Assessment) tool, complete the first validations studies both in Europe and in the U.S. and to publish it. After the full MNA®, the MNA® short form and the self-MNA® have been validated. As well as Chinese and other national MNA® forms. Now more than 2000 clinical research have used the MNA® all over the world from community care to hospital. At least 22 Expert groups included the MNA® in new clinical practice guidelines, national or international registries. The MNA® is presently included in almost all geriatric and nutrition textbook and part of the teaching program for medicine and other health care professional worldwide. The urgent need is to target the frail older adults more likely to have weight loss and poor appetite and to prevent frailty and weight loss in the robust. We present in this paper the review of 25 years of clinical research and practice using the MNA® worldwide.

Perioperative immunonutrition in hepatectomy: A systematic review and meta-analysis

Backgrounds/Aims

The role of immunonutrition (IMN) after liver resections or hepatectomies remains unclear and controversial. We undertook a systematic review to evaluate the effects of IMN on clinical outcomes of patients undergoing hepatectomy.

Methods

Main electronic databases were searched for randomised trials reported clinical outcomes or effects of IMN. The systematic review was conducted in accordance with the PRISMA guideline and meta-analysis was analysed using fixed or random-effects models.

Results

Eleven RCTs were identified. A total of 1084 patients (529 IMN and 555 Control) were included in the final pooled analysis. Of these patients, 43% (440/1016) underwent major hepatectomies and the majority are for hepatocellular carcinoma (90%, 956/1055) with Child-Pugh A disease (89%, 793/894). IMN significantly reduced post-operative wound infection (risk ratio (RR) 0.65, 95% confidence interval (CI) 0.43 to 0.96; p=0.03). IMN also had a shorter hospital stay (MD -4.97 days, 95% CI -8.23 to -1.72; p=0.003). There was no statistically significant in other post-operative morbidities and mortality.

Conclusions

Wound infection rate was not significantly different between oral and parenteral IMN group. The length of hospital stay was significantly lower in parenteral IMN group than in oral IMN group. The mortality rates were not affected. Immunonutrition should be recommended routinely as part of the nutritional support in the Enhanced Recovery after Surgery (ERAS) protocol for hepatectomy.

The Use of Visceral Proteins as Nutrition Markers: An ASPEN Position Paper

Serum albumin and prealbumin, well-known visceral proteins, have traditionally been considered useful biochemical laboratory values in a nutrition assessment. However, recent literature disputes this contention. The aim of this document is to clarify that these proteins characterize inflammation rather than describe nutrition status or protein-energy malnutrition. Both critical illness and chronic illness are characterized by inflammation and, as such, hepatic reprioritization of protein synthesis occurs, resulting in lower serum concentrations of albumin and prealbumin. In addition, the redistribution of serum proteins occurs because of an increase in capillary permeability. There is an association between inflammation and malnutrition, however, not between malnutrition and visceral-protein levels. These proteins correlate well with patients' risk for adverse outcomes rather than with protein-energy malnutrition. Therefore, serum albumin and prealbumin should not serve as proxy measures of total body protein or total muscle mass and should not be used as nutrition markers. This paper has been approved by the American Society for Parenteral and Enteral Nutrition Board of Directors.

Nutrition screening tools for risk of malnutrition among hospitalized patients: A protocol for systematic review and meta analysis

BACKGROUND

Malnutrition is a clinical problem with a high prevalence in hospitalized adult patients. Many nutritional screening tools have been developed but there is no consensus on which 1 is more useful. The purpose of this review protocol is to provide an overview of which nutritional screening tool is most valid to identify malnutritional risk in hospitalized adult patients and to analyze the sensitivity and specificity of the different tools.

METHODS

The protocol of this systematic review and meta-analysis was registered on the INPLASY website (https://inplasy.com/inplasy-2020-9-0028/) and INPLASY registration number is INPLASY202090028. We will perform a systematic literature search of main databases: PubMed, EMBASE, CINAHL and Web of Science and the Cochrane database. Also, grey literature will be search. Peer-reviewed studies published in English, Portuguese or Spanish language will be selected. Screening of titles, abstract and full text will be assessed for eligibility by 2 independent blinded reviewers and any discrepancies will be resolved via consensus. After screening the studies, a meta-analysis will be conducted, if it is possible.

RESULTS

Results from this systematic review will help health professionals to identify malnutrition in hospitalized patients and to make decisions to prevent or treat it as well as provide new clues to researchers.

CONCLUSION

Our systematic review will provide aknowledge about the most valid malnutrition risk screening tool in hospitalized adult patients.

Malnutrition in elective surgery: How traditional markers might be failing surgeons and patients

BACKGROUND

Serologic and anthropometric measures are commonly used as surrogate markers of nutritional status in clinical practice. In 2012, leading dietetic organizations published a standard definition of malnutrition based on clinical characteristics. We hypothesize that surrogate markers underrecognize clinical malnutrition and do not accurately identify patients at risk for adverse outcomes.

METHODS

A single-institution cohort study of elective surgical inpatients from August 2015 to November 2017. Nutritional assessment was completed by trained registered dietitians using leading dietetic guidelines. Multivariable logistic regression was used to determine the association between malnutrition and perioperative outcomes.

RESULTS

Among 953 elective surgical admissions, 456 underwent full clinical nutritional assessment. Of these, 202 (44.3%) met malnutrition criteria. In addition, 20.3% of patients with clinical malnutrition were underweight (<18.5 kg/m²) and 38.1% had a serum albumin <3.0 g/dL. Compared with nonmalnourished patients, those with clinical malnutrition had higher rates of any complication (46.5% vs 37.8%, P = .06), overall infectious complications (26.2% vs 14.6%, P = .002), surgical site infections (9.4% vs 3.9%, P = .02), and mortality (8.9% vs 1.9%, P = .001). Clinical malnutrition was associated with death (odds ratio 3.99; 95% confidence interval, 1.27-12.54), overall infectious complication (odds ratio 1.77; 95% confidence interval, 1.07-2.94), and surgical site infections (odds ratio 2.65; 95% confidence interval, 1.12-6.22).

CONCLUSION

In this cohort of elective surgical patients, traditional markers failed to identify malnutrition in a substantial portion of patients who met clinical malnutrition criteria. Clinical malnutrition assessment is effective in identifying patients who may be at risk for suboptimal outcomes. Surgeons should implement clinical nutritional assessment and factor that information into their preoperative evaluation and management of elective surgical patients.

Prognostic value of Mini Nutritional Assessment-Short Form with aortic valve stenosis following transcatheter aortic valve implantation

Aims

Older adults at risk for malnutrition are known to have a high mortality rate. This study aimed to investigate whether the Mini Nutritional Assessment—Short Form (MNA‐SF) could predict midterm mortality in patients undergoing transcatheter aortic valve implantation (TAVI).

Methods and results

We applied the MNA‐SF in 288 patients who had undergone TAVI from January 2016 to June 2019 at the St. Marianna University School of Medicine hospital. Using the MNA‐SF cut‐off value to indicate the risk of malnutrition, patients were divided into two groups, namely, those with an MNA‐SF score ≤11 (impaired MNA‐SF group) and those with an MNA‐SF score ≥12 (maintained MNA‐SF group). We used this value to investigate the association between the MNA‐SF and all‐cause mortality. Overall, 188 (65%) and 100 (35%) patients comprised the impaired MNA‐SF and maintained MNA‐SF groups, respectively, and 41 patients died after TAVI (mean follow‐up duration, 458 ± 315 days). Kaplan–Meier analyses showed that patients in the impaired MNA‐SF group had a significantly higher incidence of all‐cause mortality (hazard ratio 2.67; 95% confidence interval 1.29–6.21; P = 0.01). Multivariate Cox regression analyses showed that the MNA‐SF score was an independent predictor of all‐cause mortality after adjusting for the Society of Thoracic Surgeons risk score, Katz Index, and brain natriuretic peptide test results (hazard ratio 1.14; 95% confidence interval 1.01–1.28; P = 0.04).

Conclusions

The MNA‐SF was useful to screen for the risk of malnutrition in patients with TAVI and in predicting midterm prognoses in patients undergoing TAVI and could predict patient mortality after the procedure.

Prognostic Significance of Preoperative Controlling Nutritional Status Score in Patients Who Underwent Hepatic Resection for Hepatocellular Carcinoma

Malnutrition is common in patients with hepatocellualar carcinoma (HCC), and is associated with postoperative complications after hepatectomy, and also increased mortality. However, there is currently no recommendation for assessment of nutritional status in HCC patients. The controlling nutritional status (CONUT) score has been correlated with prognosis in gastrointestinal cancer patients, but there are few reports on the prognostic significance of the CONUT score in patients who underwent hepatectomy for HCC. Existing results show that patients with high CONUT scores who undergo hepatectomy for HCC have poorer survival outcomes, and experience more complications than other patients. In this paper, we review the literature, and reveal that patients who underwent hepatectomy for HCC with high preoperative CONUT scores had poorer outcomes than those with low CONUT scores. Therefore, we conclude that a preoperative CONUT score may be useful for prognostic prediction in patients with HCC undergoing curative hepatectomy.

Malnutrition in Chronic Pancreatitis: Causes, Assessment Methods, and Therapeutic Management

PURPOSE

In recent years, more and more emphasis has been placed on early diagnosis and adequate treatment of malnutrition in the course of chronic diseases (CP). One of these diseases is chronic pancreatitis in which malnutrition may develop as a consequence of abdominal pain, vomiting, diarrhea, and alcohol abuse. The aim of this review paper is recognized if we can improve the nutritional status of patients with CP.

METHODS

This paper is based on systematic literature review according to the PubMed.

RESULTS

One of the most important problems is lack of "gold standard" in screening of nutritional status in patients with CP, especially in outpatient clinics. Another problem is preventing malnutrition in these patients and beginning treatment already at significant stages of disease. To prevent malnutrition you must first recognize the causes of malnutrition in CP, adequately assess its severity using one of available questionnaires and then apply the appropriate therapeutic management. At each visit, remember to assess the nutritional status of the patient, including laboratory markers and anthropometric measurements. Patients should be advised to stop smoking and drinking alcohol and to use adequate enzyme supplementation.

CONCLUSION

Patients with CP should be led by a team of gastroenterologist, diabetologist, and psychologist and consulted by a dietitian, specialist of pain treatment, and surgeon.

Evaluation of a nutrition-risk screening tool in Lao PDR: Identifying malnutrition in a low-resource clinical setting

BACKGROUND & AIMS

Malnutrition is a top priority in Lao PDR. In 2017, 33% of children under five years of age were stunted, 21.1% were underweight, 9% were wasted while 16.6% of adults in community settings were malnourished. Rates of malnutrition are presumed to be higher among hospitalized patients however, malnutrition risk screening in inpatient settings does not occur in Lao PDR. To address this gap, this study aimed to determine the prevalence of malnutrition among hospitalized patients and investigated the inter-user reliability and validity of a nutrition-risk screening tool (NRST).

METHODS

A cross-sectional study of pediatric (n = 69) and adult (n = 125) patients was conducted at two hospitals in Vientiane, Lao PDR. Inter-observer reliability of the NRST was determined by comparing final scores of two independent observers. Validity of the NRST was determined using sensitivity, specificity, and area-under-the-receiver-operating-characteristics (ROC) curve analyses.

RESULTS

Among participants 0-4 years of age, 51% were diagnosed with malnutrition, while 58% of participants aged 5-17 years were malnourished. Among participants 18 years of age or older, 47% were diagnosed with moderate to severe malnutrition. The NRST showed 'fair' agreement between Observer 1 and Observer 2 NRST final scores (0.2737, p-value <0.001). Observer 1 and Observer 2 had a 64% and 70% probability of correctly distinguishing a malnourished from a not malnourished participant. The Lao NRST had a sensitivity of 85% and a specificity 35%.

CONCLUSION

There is a high prevalence of malnutrition among hospitalized patients in Lao PDR. This study provides proof of concept that a nutrition-risk screening tool can be successfully administered in a low-resource setting. Timely identification of malnutrition among newly admitted hospitalized patients will help minimize adverse patient health outcomes and reduce the economic burden of healthcare in Lao PDR.

Computed Tomography-Measured Psoas Muscle Density as a Predictive Factor for Hypophosphatemia Associated With Refeeding

BACKGROUND

Initiation of parenteral nutrition (PN) after a period of starvation can be complicated by refeeding syndrome (RFS). RFS is associated with electrolyte abnormalities including hypomagnesemia, hyponatremia, and hypophosphatemia. Risk factors include recent weight loss, low body mass index, and electrolyte deficiencies; however, these associations are not strong. We hypothesized that a validated measure of nutrition risk, computed tomography (CT)-measured psoas muscle density, can be used to predict the development of hypophosphatemia associated with RFS.

METHODS

A retrospective analysis of surgical patients initiated on PN with an abdominal CT scan within the past 3 months was conducted. CT-measured psoas muscle density was assessed as a predictive variable for the development of electrolyte abnormalities. Daily electrolyte and clinical outcome measures were recorded.

RESULTS

One hundred nine patients were stratified based on Hounsfield unit average calculation (HUAC). The lowest 25th percentile of patients had HUAC <25. Low HUAC was associated with a significant percent decrease in phosphate levels from baseline to PN day 3 (P < .01) and significant difference in serum phosphate value on PN day 3 (P < .01). The low muscle density quartile also experienced longer days on the mechanical ventilator (P = .01) compared with patients with a higher psoas muscle density.

CONCLUSION

Psoas muscle density predicted the development of hypophosphatemia in patients initiated on PN. This measurement may aid in identifying patients at highest risk of experiencing RFS. A mean psoas HU <25 may prompt additional precautions, including additional phosphate replacement and slower initiation of PN.

Relationship of Nutritional Status, Inflammation, and Serum Albumin Levels During Acute Illness: A Prospective Study

BACKGROUND

Low serum albumin levels resulting from inflammation-induced capillary leakage or disease-related anorexia during acute illness are associated with poor outcomes. We investigated the relationship of nutritional status and inflammation with low serum albumin levels and 30-day mortality in a large cohort.

METHODS

We prospectively enrolled adult patients in the medical emergency department of a Swiss tertiary care center and investigated associations of C-reactive protein (CRP) and Nutritional Risk Screening 2002 as markers of inflammation and poor nutritional status, respectively, with low serum albumin levels and mortality using multivariate regression analyses.

RESULTS

Among the 2465 patients, 1019 (41%) had low serum albumin levels (<34 g/L), 619 (25.1%) had increased nutritional risk (Nutritional Risk Screening 2002 ≥3), and 1086 (44.1%) had CRP values >20 mg/L. Multivariate analyses adjusted for age, gender, diagnosis, and comorbidities revealed elevated CRP values (adjusted odds ratio [OR] 10.51, 95% confidence interval, 7.51-14.72, P <.001) and increased malnutrition risk (adjusted OR 2.87, 95% confidence interval, 1.98-4.15, P <.001) to be associated with low serum albumin levels, even adjusting for both parameters. Low serum albumin levels, elevated CRP values, and increased nutritional risk independently predicted 30-day mortality, with areas under the curve of 0.77, 0.70, and 0.75, respectively. Combination of these 3 parameters showed an area under the curve of 0.82 to predict mortality.

CONCLUSIONS

Elevated parameters of inflammation and high nutritional risk were independently associated with hypoalbuminemia. All 3 parameters independently predicted mortality. Combining them during initial evaluation of patients in emergency departments facilitates mortality risk stratification.

Malnutrition, Health and the Role of Machine Learning in Clinical Setting

Nutrition plays a vital role in health and the recovery process. Deficiencies in macronutrients and micronutrients can impact the development and progression of various disorders. However, malnutrition screening tools and their utility in the clinical setting remain largely understudied. In this study, we summarize the importance of nutritional adequacy and its association with neurological, cardiovascular, and immune-related disorders. We also examine general and specific malnutrition assessment tools utilized in healthcare settings. Since the implementation of the screening process in 2016, malnutrition data from hospitalized patients in the Geisinger Health System is presented and discussed as a case study. Clinical data from five Geisinger hospitals shows that ~10% of all admitted patients are acknowledged for having some form of nutritional deficiency, from which about 60-80% of the patients are targeted for a more comprehensive assessment. Finally, we conclude that with a reflection on how technological advances, specifically machine learning-based algorithms, can be integrated into electronic health records to provide decision support system to care providers in the identification and management of patients at higher risk of malnutrition.

Is the handgrip strength a good nutritional assessment method for people living with HIV?

ABSTRACT Objective The study aimed to verify the relationship between handgrip strength measurement and classic anthropometric values in HIV positive outpatients. Methods This was a cross-sectional study that enrolled HIV-positive outpatients treated at the Gaffrée and Guinle University Hospital, aged between 20 and 60 years and considered to be well-nourished or moderately malnourished, according to the Global Subjective Analysis. The patients’ bilateral handgrip strength were assessed (Jamar dynamometer), and classic anthropometry variables (weight, height, body mass index, arm muscle area, arm fat area, arm muscle circumference, and triceps skin fold) were measured. The Kolmogorov-Smirnov test, t-test, bivariate correlation and regression analysis were used (SPSS 21® software), with a significance level of 5%. Results A total of 242 patients were assessed. According to the Global Subjective Analysis, 218 (90.1%) patients were classified as well nourished (Global Subjective Analysis-A) and 24 (9.9%) as moderately malnourished (Global Subjective Analysis-B). The average dominant hand handgrip strength with standard deviation was 30.5±9.5kgf and 24.1±6.1kgf for Global Subjective Analysis-A and Global Subjective Analysis-B patients, respectively. Handgrip values were not influenced by age. The handgrip strength showed in both genders a significant correlation with weight, body mass index, and with anthropometric parameters related to lean body mass (arm muscle circumference and arm muscle area), but without correlation with the non-lean mass parameter (arm fat area). The handgrip strength of the dominant hand was a predictor of the following variables associated with lean body mass, i.e., arm muscle circumference and arm muscle area (R2=0.194, t=7.7, p<0.001, and R2=0.192, t=7.6, p<0.001, respectively). However, handgrip strength was not a predictor of arm fat area. Conclusion Measurement of handgrip strength was a useful method for nutritional assessment in outpatients with HIV due to a significant relationship with anthropometric parameters associated with lean body mass.

Hypoglycemia, Malnutrition and Body Composition

Hypoglycemia is one of the most significant factors to affect prognosis, and is detrimental to patients regardless of diabetes mellitus (DM) status. The classical paradigms dictate that hypoglycemia is a result of overtreatment with glucose lowering agents (iatrogenic hypoglycemia), or, as among patients without DM, this condition is attributed to disease severity. New information shows that hypoglycemia occurs among patients that have a tendency for it. Incident hypoglycemia is very prevalent in the hospital setting, occurring in 1:6 patients with DM and in 1:17 patients without DM (Leibovitz E, Khanimov I, Wainstein J, Boaz M; Diabetes Metab Syndr Clin Res Rev. 13:222-226, 2019).One of the major factors associated with incidence of hypoglycemia is the nutritional status on hospital admission and during the hospitalization. Assessment of nutritional status using questionnaires and biomarkers might be helpful in determining risk of hypoglycemia. Moreover, administration of oral nutritional supplements was shown to decrease this risk.It is also well known that a high burden of comorbidities is associated with an increased risk of hypoglycemia. For example, kidney disease, whether acute or chronic, was shown to increase the risk for hypoglycemia, as well as some endocrine disorders.In this review we elaborate on specific findings that are characteristic of patients at risk for developing hypoglycemia, as well as treatment aimed at preventing its occurrence.

A New Approach to Comprehensive Growth and Nutrition Assessment in Children

A new approach to comprehensive growth and nutrition assessment of infants, children, and adolescents that is etiology based and relatively simple to implement is now available. It encompasses five domains: anthropometry (growth measurements), assessment of change in growth (growth dynamism), duration of the growth abnormalities, etiology of the nutritional imbalance, and impact of the nutritional state on functional outcomes. Its increased use will help to standardize the screening, diagnosis, and documentation of malnutrition in both ambulatory and hospitalized patients. [Pediatr Ann. 2019;48(11):e425-e433.].
