Abstract
Making arrangements by learning how intensive care patients feel due to a disease called as fatal worldwide can make it easier for patients to cope with the disease. For this reason, it is important for healthcare professionals to understand the patients who have been infected and discharged during the COVID-19 pandemic. The experiences of the patients may affect the perspective of the disease and cause different changes in the perception of it. This study, which was conducted based on this idea, aimed to examine the intensive care experiences of patients discharged from the COVID-19 intensive care unit. This study used a phenomenological qualitative approach. A semi-structured interview form was used to interview 23 patients discharged from the COVID-19 intensive care unit. The findings were reported on the basis of consolidated criteria for reporting qualitative research. In line with the data obtained from the interviews, five main themes and eight subthemes were created. The main themes were classified as emotional expressions (positive/negative) related to intensive care experience, coping methods, analogies (for COVID-19 and nurses) and attitudes towards the care provided (respiration, nutrition, excretion and privacy, sleep, communication). In this study, the participants experienced negative emotions such as fear of death/anxiety, sadness, loneliness, and helplessness during their intensive care experiences. Most of them stated that they tried to cope with prayer and communication. The participants compared COVID-19with deadly and respiratory-inhibiting tools and diseases. They expressed difficulties in breathing, nutrition, excretion and privacy, sleep and communication related to the care provided. In this process, they made positive analogies for the nurses who spent the most time with them, such as angels and family members.

Chiang CY, Lan CC, Yang CH, Hou YC. Investigating the differences in nutritional status between successfully weaned and unsuccessfully weaned respirator patients. Sci Rep 2023; 13:7144. [PMID: 37130876 PMCID: PMC10154359 DOI: 10.1038/s41598-023-34432-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2022] [Accepted: 04/29/2023] [Indexed: 05/04/2023] Open
Abstract
Long-term respirator users admitted to intensive care units need to be transferred to a respiratory care center (RCC) for weaning. It may cause malnutrition in critical care patients, which may manifest as a reduction in respiratory muscle mass, lower ventilatory capacity, and decreased respiratory tolerance. This study aimed to assess that if the patients' nutritional status were improved, it could help RCC patients to wean from respirators. All participants were recruited from the RCC of a medical foundation in the city and Taipei Tzu Chi Hospital. The indicators include serum albumin level, respirator detachment index, maximum inspiratory pressure (PImax), rapid shallow breathing index, and body composition measurements. We recorded the length of hospital stay, mortality, and RCW (respiratory care ward) referral rate for these participants and analyzed the differences in relevant research indicators between those who were and weren't weaned off. 43 of 62 patients were weaned from respirators, while 19 failed. The resuscitation rate was 54.8%. Patients with respirator weaning had a lower number of RCC admission days (23.1 ± 11.1 days) than respirator-dependent patients (35.6 ± 7.8 days, P < 0.05). The PImax of successfully weaned patients had a greater reduction (- 27.09 ± 9.7 cmH2O) than unsuccessful ones (- 21.4 ± 10.2 cmH2O, P < 0.05). The Acute Physiology and Chronic Health Evaluation II (APACHE II) scores of successfully weaned patients (15.8 ± 5.0) were lower than those who were not (20.4 ± 8.4, P < 0.05). There was no significant difference in serum albumin levels between the two groups. In the successfully weaned patients, the serum albumin concentration was increased from 2.2 ± 0.3 to 2.5 ± 0.4 mg/dL, P < 0.05. Improved nutritional status can help RCC patients to wean from respirators.

Abstract
Successful weaning from ventilators not only improves the quality of life of patients, but also reduces medical expenses. The aim of this study was to explore the association between nutritional provision and successful ventilator weaning. In this retrospective study data from the Respiratory Care Center of Chung Shan Medical University Hospital between October, 2017 and July, 2019 on patient characteristics, amount of nutrition delivered, and clinical outcomes were retrieved. A total of 280 ventilated patients were enrolled and divided into successful extubation and failed weaning groups. There were 178 males (63.6%) and 102 females (36.4%) with a mean age of 67.3 ± 16.9 years. The successful extubation group consisted of patients who tended towards ideal body weight during the weaning process (BMI 23.9 ± 5.0 versus 22.7 ± 4.8 kg/m2, p < 0.001). Patients from both groups initially received the same nutritional intervention, while patients of successful extubation received significantly more calories and protein after weaning (23.8 ± 7.8 kcal versus 27.8 ± 9.1 kcal, p < 0.001 and 0.97 ± 0.36 g versus 1.14 ± 0.42 g, p < 0.001). Successful weaning was associated with higher survival rate (p = 0.016), shortened hospital stay (p = 0.001), and reduced medical costs (p < 0.001). Overall, nutritional support with high calories and protein was associated with the probability of successful ventilator weaning in patients undergoing prolonged mechanical ventilation. Adequate nutrition is a determinant of successful ventilator weaning.

Abstract
Acute kidney injury (AKI), often present in critically ill patients and patients with cardiac dysfunction, may alter estimates of renal function. The impact of recent AKI on the accuracy of the Cockcroft-Gault creatinine clearance equation (CG-CrCl) before cardiac surgery is unknown. This single-center, retrospective study included patients who underwent cardiac surgery from 1 January 2006 through 30 June 2012 and whose 24-hour urine creatinine clearance (24hr-CrCl) was measured in the intensive care unit before surgery. We evaluated CG-CrCl accuracy by calculating absolute differences between 24hr-CrCl and CG-CrCl estimates. Clinical impact was signified by discrepancies in United States Food and Drug Administration (FDA) renal impairment stage indicated by 24hr-CrCl versus CG-CrCl estimates. Acute kidney injury was evaluated by using Kidney Disease: Improving Global Outcomes criteria. Of 161 patients, 93 (58%) had recent AKI: stage 1, 31 (33%); stage 2, 39 (42%); and stage 3, 23 (25%). In mL/min, the CG-CrCl overestimated 24hr-CrCl (absolute difference: total, -10 ± 25; no AKI, -7 ± 26; stage 1, -8 ± 17; stage 2, -16 ± 28; and stage 3, -10 ± 26; P=0.29). Renal impairment stages assigned by CG-CrCl did not match 24hr-CrCl in 70 (43%) of the 161 patients, especially those with recent AKI: no AKI, 24/68 (35%); stage 1, 13/31 (42%); stage 2, 23/39 (59%); and stage 3, 10/23 (43%). The CG-CrCl consistently overestimated 24hr-CrCl in critically ill patients before cardiac surgery. Clinicians should use the CG-CrCl cautiously when estimating renal function and medication dosages in this population.

Abstract
BACKGROUND Uncertainty remains about the best route and timing of medical nutrition therapy in the acute phase of critical illness. Early combined enteral nutrition (EN) and parenteral nutrition (PN) may represent an attractive option to achieve recommended energy and protein goals in select patient groups. This meta-analysis aims to update and summarize the current evidence. METHODS This systematic review and meta-analysis includes randomized controlled trials (RCTs) targeting the effect of EN alone vs a combination of EN with PN in the acute phase of critical illness in adult patients. Assessed outcomes include mortality, intensive care unit (ICU) and hospital length of stay (LOS), ventilation days, infectious complications, physical recovery, and quality-of-life outcomes. RESULTS Twelve RCTs with 5543 patients were included. Treatment with a combination of EN with PN led to increased delivery of macronutrients. No statistically significant effect of a combination of EN with PN vs EN alone on any of the parameters was observed: mortality (risk ratio = 1.0; 95% CI, 0.79-1.28; P = .99), hospital LOS (mean difference, -1.44; CI, -5.59 to 2.71; P = .50), ICU LOS, and ventilation days. Trends toward improved physical outcomes were observed in two of four trials. CONCLUSION A combination of EN with PN improved nutrition intake in the acute phase of critical illness in adults and was not inferior regarding the patients' outcomes. Large, adequately designed trials in select patient groups are needed to answer the question of whether this nutrition strategy has a clinically relevant treatment effect.

Abstract
Nutrition therapy, by enteral, parenteral, or both routes combined, is a key component of the management of critically ill, surgical, burns, and oncology patients. Established evidence indicates overfeeding (provision of excessive calories) results in increased risk of infection, morbidity, and mortality. This has led to the practice of "permissive underfeeding" of calories; however, this can often lead to inadequate provision of guideline-recommended protein intakes. Acutely ill patients requiring nutritional therapy have high protein requirements, and studies demonstrate that provision of adequate protein can result in reduced mortality and improvement in quality of life. However, a significant challenge to adequate protein delivery is the current lack of concentrated protein solutions. Patients often have fluid administration restrictions and existing protein solutions are frequently not sufficiently concentrated to deliver a patient's protein requirements. This has led to the development of new enteral and parenteral nutrition solutions incorporating higher levels of protein in smaller volumes. This review article summarizes current evidence supporting the role of higher protein intakes, especially during the early phases of nutrition therapy in acute illness, methods for assessing protein requirements, as well as, the currently available high-protein enteral and parenteral nutrition solutions. There is sufficient evidence (albeit limited from true randomized, controlled studies) to indicate that earlier provision of guideline-recommended protein intakes may be key to improving patient outcomes and that nutritional therapy that tailors caloric and protein intake to the patients' needs should be considered a desired standard of care.

Effect of Supplemental Parenteral Nutrition Versus Enteral Nutrition Alone on Clinical Outcomes in Critically Ill Adult Patients: A Systematic Review and Meta-Analysis of Randomized Controlled Trials. Nutrients 2020; 12:E2968. [PMID: 32998412 PMCID: PMC7601814 DOI: 10.3390/nu12102968] [Citation(s) in RCA: 24] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2020] [Revised: 09/16/2020] [Accepted: 09/25/2020] [Indexed: 02/07/2023] Open
Abstract
Enteral nutrition (EN) is considered the first feeding route for critically ill patients. However, adverse effects such as gastrointestinal complications limit its optimal provision, leading to inadequate energy and protein intake. We compared the clinical outcomes of supplemental parenteral nutrition added to EN (SPN + EN) and EN alone in critically ill adults. Electronic databases restricted to full-text randomized controlled trials available in the English language and published from January 1990 to January 2019 were searched. The risk of bias was evaluated using the Jadad scale, and the meta-analysis was conducted using the MedCalc software. A total of five studies were eligible for inclusion in the systematic review and meta-analysis. Compared to EN alone, SPN + EN decreased the risk of nosocomial infections (relative risk (RR) = 0.733, p = 0.032) and intensive care unit (ICU) mortality (RR = 0.569, p = 0.030). No significant differences were observed between SPN + EN and EN in the length of hospital stay, hospital mortality, length of ICU stay, and duration of mechanical ventilation. In conclusion, when enteral feeding fails to fulfill the energy requirements in critically ill adult patients, SPN may be beneficial as it helps in decreasing nosocomial infections and ICU mortality, in addition to increasing energy and protein intakes with no negative effects on other clinical outcomes.

Abstract
BACKGROUND & AIMS Hospital malnutrition is a prevalent yet frequently under-recognised condition that is associated with adverse clinical and economic consequences. Systematic reviews from various regions of the world have provided regional estimates of the prevalence of malnutrition and the magnitude of the associated health and economic burden; however, a systematic assessment of the prevalence and consequences of hospital malnutrition in northeast and southeast Asia has not been conducted. METHODS We performed a systematic literature search for articles on hospital malnutrition in 11 Asian countries published in English between January 1, 1997 and January 15, 2018. Studies reporting data on the prevalence, clinical consequences, or economic impact of hospital malnutrition in an adult inpatient population with a sample size ≥30 were eligible for inclusion. RESULTS The literature search identified 3207 citations; of these, 92 studies (N = 62,280) met the criteria for inclusion. There was substantial variability in study populations and assessment methods; however, a majority of studies reported a malnutrition prevalence of >40%. Malnutrition was associated with an increase in clinical complications, mortality, length of hospitalisation, hospital readmissions, and healthcare costs. CONCLUSIONS Hospital malnutrition is a highly prevalent condition among hospitalised patients in northeast and southeast Asia. Additionally, poor nutritional status is associated with increased morbidity and mortality and increased healthcare costs. Further research aimed at improving the identification and proactive management of hospitalised patients at risk for malnutrition is necessary to improve patient outcomes and alleviate the burden on local healthcare budgets.

Abstract
In idiopathic pulmonary fibrosis (IPF), several factors may have a negative impact on the nutritional status, including an increased respiratory muscles load, release of inflammation mediators, the coexistence of hypoxemia, and physical inactivity. Nutritional abnormalities also have an impact on IPF clinical outcomes. Given the relevance of nutritional status in IPF patients, we sought to focus on some critical issues, highlighting what is known and what should be further learned about these issues. We revised scientific literature published between 1995 and August 2019 by searching on Medline/PubMed and EMBASE databases including observational and interventional studies. We conducted a narrative review on nutritional assessment in IPF, underlining the importance of nutritional evaluation not only in the diagnostic process, but also during follow-up. We also highlighted the need to keep a high level of attention on cardiovascular comorbidities. We also focused on current clinical treatment in IPF with Nintedanib and Pirfenidone and management of gastrointestinal adverse events, such as diarrhea, induced by these antifibrotic drugs. Finally, we concentrated on the importance of pulmonary rehabilitation program, including nutritional assessment, education and behavioral change, and psychological support among its essential components. More attention should be devoted to the assessment of the undernutrition and overnutrition, as well as of muscle strength and physical performance in IPF patients, taking also into account that an adequate clinical management of gastrointestinal complications makes IPF drug treatments more feasible.

Abstract
BACKGROUND Whether combined parenteral nutrition (PN) and enteral nutrition (EN) is superior to EN alone remains controversial. OBJECTIVES This study aimed to evaluate the efficacy and safety of combined PN and EN versus EN alone for critically ill patients based on published randomized controlled trials (RCTs). DATA SOURCES Studies designed as RCTs evaluating the treatment effectiveness of combined PN and EN versus EN alone for critically ill patients were identified from PubMed, Embase, and the Cochrane Library from inception to April 2019. METHODS The pooled relative risks and weighted mean differences with corresponding 95% confidence intervals were calculated using the random-effects model. Twelve RCTs recruiting a total of 5609 adults and 1440 children were selected for the final meta-analysis. RESULTS The summary relative risks indicated that combined PN and EN was not associated with the risk of all-cause mortality, respiratory infection, urinary tract infection, and nutrition-related complications. Moreover, combined PN and EN was associated with longer hospital stay and higher albumin and prealbumin levels compared with EN alone. No significant differences were, however, found between combined PN and EN and EN alone in terms of ventilatory support, intensive care unit stay, and transferrin and C-reactive protein levels. CONCLUSIONS This study showed that combined PN and EN significantly increased hospital stay duration and albumin and prealbumin levels compared with EN alone for critically ill patients. Large-scale RCTs should be conducted to compare the treatment effectiveness of combined PN and EN versus EN alone for critically ill patients due to a specific cause.

The Relationship between Serum Concentrations of Pro- and Anti-Inflammatory Cytokines and Nutritional Status in Patients with Traumatic Head Injury in the Intensive Care Unit. MEDICINA (KAUNAS, LITHUANIA) 2019; 55:E486. [PMID: 31443251 PMCID: PMC6723863 DOI: 10.3390/medicina55080486] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 06/29/2019] [Revised: 08/12/2019] [Accepted: 08/12/2019] [Indexed: 01/04/2023]
Abstract
Background and objective: The aim of the present study was to examine the relationship between serum levels of pro-inflammatory cytokines (IL-6, IL-1β, and TNF-α) and anti-inflammatory cytokines (IL-10) measured once at the baseline with changes in nutritional status of patients with traumatic head injury (THI) assessed at three consecutive times (24 h after admission, day 6 and day 13) during hospital stay in the intensive care unit (ICU). Materials and Methods: Sixty-four patients with THI were recruited for the current study (over 10 months). The nutritional status of the patients was determined within 24 h after admission and on days 6 and 13, using actual body weight, body composition analysis, and anthropometric measurements. The APACHE II score and SOFA score were also assessed within 24 h of admission and on days 6 and 13 of patients staying in the ICU. Circulatory serum levels of cytokines (IL-6, IL-1β, TNF-α, and IL-10) were assessed once within 24 h of admission. Results: The current study found a significant reduction in BMI, FBM, LBM, MAUAC, and APM, of THI patients with high serum levels the cytokines, over the course of time from the baseline to day 7 and to day 13 in patients staying in the ICU (p < 0.001). It was also found that patients with low levels of some studied cytokines had significant improvement in their nutritional status and clinical outcomes in term of MAUAC, APM, APACHE II score and SOFA score (p < 0.001 to p < 0.01). Conclusion: THI patients who had high serum levels of studied cytokines were more prone to develop a reduction of nutritional status in terms of BMI, FBM, LBM MAUAC and APM over the course of time from patient admission until day 13 of ICU admission.

Abstract
BACKGROUND AND AIM The increased mortality rate and other poor prognosis make malnutrition a serious issue for adult critically ill patients in intensive care unit care. This study was to compare outcomes between combined parenteral and enteral nutrition and enteral nutrition alone for adult critically ill patients. MATERIALS AND METHODS The PubMed (June 30, 2018), EMBASE (June 30, 2018), and Cochrane library databases (June 30, 2018) were searched systematically. Randomized controlled trials (RCTs) of comparing combined PN and EN with EN alone were eligible. Relative risks (RRs), mean differences (MDs), and 95% confidence intervals (CIs) were calculated for dichotomous and continuous outcomes. RESULTS Eight RCTs involving 5360 patients met the inclusion criteria. Compared with combined PN and EN, fewer respiratory infections (RR, 1.13 [95% CI 1.01-1.25]) and shorter length of days at hospital (MD, 1.83 [95% CI 1.05-2.62]) were observed in EN alone group. And no significant differences were found on hospital mortality (RR, 0.91 [95% CI 0.74-1.12]), length of days in ICU (MD, -0.23 [95% CI -1.79 to 1.32]), duration of ventilatory support (MD, -1.10 [95% CI -3.15 to 0.94]), albumin (MD, -0.04 [95% CI, -0.12 to 0.21]), or prealbumin (MD, -0.77 [95% CI -0.22 to 1.75]) between theses 2 groups. CONCLUSION Receiving EN alone decreased the respiratory infections and length of days at hospital for critically ill patients. Combined PN and EN did not add up the potential risk from PN and EN on hospital mortality, length of days in ICU, duration of ventilatory support, albumin, and prealbumin.

Abstract
BACKGROUND Nutrition monitoring in the context of critical care presents unique challenges. Traditionally used anthropometric and biochemical markers may be difficult to obtain or confounded by factors such as fluid status and the inflammatory response. A previous survey identified 15 parameters in common use, all of which have confounding influences during critical illness. MATERIALS AND METHODS A literature search was conducted to assess current use of commonly used nutrition-monitoring parameters and to explore other possible methods that might be more useful. More than 1000 journal articles were reviewed to identify indicators of nutrition status or nutrition progress that have been used in ICU studies. The most recent 200 articles were examined to quantify the number of occurrences for each indicator. Each parameter was rated for availability and feasibility in the ICU. RESULTS There were 53 parameters found, including the 15 already identified as commonly used; 27 were used in ≥3 recent studies. Less-well-established nutrition indicators with potential for use in the ICU (moderate or high feasibility and availability) included ultrasound measurement of arm or leg muscle thickness, fatigue scoring with the Chalder scale, urinary creatinine assay, and serum insulin-like growth factor 1 level. None of these was among the commonly used indicators in recent studies. CONCLUSION This study identifies commonly used nutrition-monitoring parameters and discusses their feasibility and availability in the critical care setting. Further investigation of nutrition indicators in ICU is needed, ideally as part of a randomized trial to reduce the effect of the many possible confounding factors.

Abstract
INTRODUCTION Nutrition support is one of the most common care, which is undertaken for patients who suffered from Traumatic Brain Injury (TBI) and are admitted in intensive care units. Literature indicates some controversies regarding the appropriate method of nutrition support in these patients. AIM This study was conducted for determining the effect of continuous enteral nutrition on nutrition indices, compared to the intermittent enteral and combination nutrition in TBI patients. MATERIALS AND METHODS In a randomized clinical trial, 60 TBI patients who were admitted to critical care units of Taleghani Hospital of Kermanshah-Iran in 2010 recruited to the study. The samples were allocated to three groups of continuous enteral nutrition, intermittent enteral nutrition and combination nutrition supports by random sampling. The tool was a researcher-made checklist. The three methods of nutrition support were performed to the participants, then nutrition indices of patients were measured before and during three weeks. Data were analysed using SPSS software, descriptive, and inferential statistics. RESULTS The mean of received energy in the combination group (53.1± 18.3%) was higher than continuous (38.5±19.7%) and intermittent (32.2±14.7%) groups, significantly (p<0.001). The received protein was also greater in combination method (67.7±16.9%) than continuous (31.8±15.1%) and intermittent groups (17.2±10.1%), (p=0.001). The mean of nitrogen balance was improved in continuous method from -4.7± -1.6 to 7.2±5.2, (p<0.001) significantly. CONCLUSION In this study, received energy of patients was not enough by three methods. However, the continuous method, having a positive effect on nitrogen balance, reducing hypercatabolism and maintaining the total body protein, was preferred to brain injury patients compared with intermittent enteral and parenteral methods that demand more studies.

Abstract
BACKGROUND Malnutrition is an important factor in the survival of critically ill patients. The purpose of the present study was to assess the nutritional status of patients in the intensive care unit (ICU) on the days of admission and discharge via a detailed nutritional assessment. METHODS Totally, 125 patients were followed up from admission to discharge at 8ICUs in Shiraz, Iran. The patients' nutritional status was assessed using subjective global assessment (SGA), anthropometric measurements, biochemical indices, and body composition indicators. Diet prescription and intake was also evaluated. RESULTS Malnutrition prevalence significantly increased on the day of discharge (58.62%) compared to the day of admission (28.8%) according to SGA (P<0.001). The patients' weight, mid-upper-arm circumference, mid-arm muscle circumference, triceps skinfold thickness, and calf circumference decreased significantly as well (P<0.001). Lean mass weight and body cell mass also decreased significantly (P<0.001). Biochemical indices showed no notable changes except for magnesium, which decreased significantly (P=0.013). A negative significant correlation was observed between malnutrition on discharge day and anthropometric measurements. Positive and significant correlations were observed between the number of days without enteral feeding, days delayed from ICU admission to the commencement of enteral feeding, and the length of ICU stay and malnutrition on discharge day. Energy and protein intakes were significantly less than the prescribed diet (26.26% and 26.48%, respectively). CONCLUSION Malnutrition on discharge day increased in the patients in the ICU according to SGA. Anthropometric measurements were better predictors of the nutritional outcome of our critically ill patients than were biochemical tests.

Abstract
BACKGROUND Accurate assessment of nutrition status is essential in identifying subpopulations of critically ill patients who are malnourished and at higher mortality risk. The aim of this analytic observational study was to assess the performance of physical assessment and anthropometric measures commonly used in clinical research. METHODS A prospective study was undertaken in 31 intensive care units (ICUs) with a focus on patients with short-term contraindications to enteral nutrition. Within 24 hours of admission to the ICU, the following measures were collected: the Subjective Global Assessment components measuring subcutaneous fat loss and muscle wasting, height, weight, mid-upper-arm circumference, and triceps skinfold thickness (TSF). Mid-arm muscle circumference and body mass index (BMI) were calculated. BMI was assessed as a continuous variable and categorized according to the World Health Organization (WHO) categories. The primary outcome was hospital discharge mortality. RESULTS In total, 1363 patients were enrolled. BMI, analyzed according to WHO categories (P = .09), and TSF (P = .32) failed to demonstrate statistically significant predictive ability. TSF failed to demonstrate statistically significant clinical utility (area under the receiver operating characteristic curve, 0.52; 95% confidence interval, 0.48-0.56). All other individual measures demonstrated statistically significant predictive ability and statistically significant clinical utility. CONCLUSIONS On the basis of the results of our ICU cohort, we recommend caution when using BMI categorized according to WHO definitions. We cannot recommend collection of TSF. More research is required to understand reliability, performance, and use before our results are able to be generalized to other ICU populations.

Abstract
Critical illness dramatically increases muscle proteolysis and more than doubles the dietary protein requirement. Yet surprisingly, most critically ill patients receive less than half the recommended amount of protein during their stay in a modern intensive care unit. What could explain the wide gap between the recommendations in clinical care guidelines and actual clinical practice? We suggest that an important aspect of the problem is the failure of guidelines to explain the pathophysiology of protein-energy malnutrition and the ways critical illness modifies protein metabolism. The difficulty created by the lack of a framework for reasoning about appropriate protein provision in critical illness is compounded by the many ambiguous and often contradictory ways the word malnutrition is used in the critical care literature. Failing to elucidate these matters, the recommendations for protein provision in the guidelines are incoherent, unconvincing, and easy to ignore.

Abstract
OBJECTIVE To analyze the nutritional status of pediatric patients after orthotopic liver transplantation and the relationship with short-term clinical outcome. METHOD Anthropometric evaluations of 60 children and adolescents after orthotopic liver transplantation, during the first 24 hours in a tertiary pediatric intensive care unit. Nutritional status was determined from the Z score for the following indices: weight/age height/age or length/age, weight/height or weight/length, body mass index/age, arm circumference/age and triceps skinfold/age. The severity of liver disease was evaluated using one of the two models which was adequated to the patients' age: 1. Pediatric End-stage Liver Disease, 2. Model for End-Stage Liver Disease. RESULTS We found 50.0% undernutrition by height/age; 27.3% by weight/age; 11.1% by weight/height or weight/ length; 10.0% by body mass index/age; 61.6% by arm circumference/age and 51.0% by triceps skinfold/age. There was no correlation between nutritional status and Pediatric End-stage Liver Disease or mortality. We found a negative correlation between arm circumference/age and length of hospitalization. CONCLUSION Children with chronic liver diseases experience a significant degree of undernutrition, which makes nutritional support an important aspect of therapy. Despite the difficulties in assessment, anthropometric evaluation of the upper limbs is useful to evaluate nutritional status of children before or after liver transplantation.

Abstract
INTRODUCTION To develop a scoring method for quantifying nutrition risk in the intensive care unit (ICU). METHODS A prospective, observational study of patients expected to stay > 24 hours. We collected data for key variables considered for inclusion in the score which included: age, baseline APACHE II, baseline SOFA score, number of comorbidities, days from hospital admission to ICU admission, Body Mass Index (BMI) < 20, estimated % oral intake in the week prior, weight loss in the last 3 months and serum interleukin-6 (IL-6), procalcitonin (PCT), and C-reactive protein (CRP) levels. Approximate quintiles of each variable were assigned points based on the strength of their association with 28 day mortality. RESULTS A total of 597 patients were enrolled in this study. Based on the statistical significance in the multivariable model, the final score used all candidate variables except BMI, CRP, PCT, estimated percentage oral intake and weight loss. As the score increased, so did mortality rate and duration of mechanical ventilation. Logistic regression demonstrated that nutritional adequacy modifies the association between the score and 28 day mortality (p = 0.01). CONCLUSIONS This scoring algorithm may be helpful in identifying critically ill patients most likely to benefit from aggressive nutrition therapy.

Abstract
Attenuation of muscle wasting has been reported with eicosapentaenoic acid (EPA) use in cachectic states. Pathways mediating muscle proteolysis with severe short-term nutritional deprivation (ND)±EPA were evaluated, including diaphragm fiber-specific cross-sectional areas, mRNA (real-time PCR) and protein expression (Western blot). Rats were divided into three groups: (1) free-eating controls, (2) ND and (3) ND+EPA. ND significantly influenced multiple proteolytic pathways. EPA significantly reduced mRNA abundances for most genes to control levels with ND. However, discordant muscle protein expression of many genes was noted with the use of EPA, as protein levels failed to fall. EPA had no impact on diaphragm muscle atrophy, despite the impressive mRNA and some protein results. We conclude that EPA does not attenuate diaphragm muscle atrophy with severe levels of ND. Postulated mechanisms include reduction in muscle protein synthesis and persistent ongoing stimuli for proteolysis. Our study provides unique data on proteolytic signals with ND and has important implications for future studies using EPA.

Abstract
BACKGROUND Critically ill patients frequently receive inadequate nutrition support as a result of under- or overfeeding. Malnutrition in intensive care unit (ICU) patients is associated with increased morbidity and mortality. The present study aimed to identify the significant factors that influence energy deficit in the ICU. METHODS ICU patients with a length of stay of ≥3 days were studied for 30 days over two consecutive years at a large university teaching hospital. Fifty-six Patients were studied, with a total of 530 records of feeding days. Information was collected for: day when feed initiated, age, gender, length of stay, Acute Physiological and Chronic Health Evaluation score (APACHE II), fed within 24 h, speciality, type of ventilation, feeding route, outcome (survived/died), diarrhoea (yes/no), aspirate volume, dietitian observed nutritional status (malnourished/not), sedation, estimated energy requirements and energy received. Mixed linear models for longitudinal data were used with energy deficit (energy received - energy requirements) as the dependent variable. RESULTS Factors that were found to have a significant association with energy deficit were: day feeding was initiated (P<0.001), whether fed within 24 h (P<0.001) and whether sedated (P<0.001). Furthermore, three combined effects were found: ventilation mode and aspirate volume (P<0.007), fed within 24 h and ventilation mode (P<0.001), fed within 24 h and sedation (P<0.017). CONCLUSIONS The number of days after feeding was initiated, initiation of feeding within 24 h and sedation have been identified as factors that predict energy deficit during ICU stay. Efforts to initiate feeding as soon as possible and minimise interruptions to feeding may reduce energy deficits in these vulnerable patients.

Abstract
Total parenteral nutrition was developed in the 1960s and has since been implemented commonly in the intensive care unit (ICU). Studies published in the 1980s and early 1990s indicate that the use of total parenteral nutrition is associated with increased mortality and infectious morbidity. These detrimental effects were related to hyperglycemia and overnutrition at a period when parenteral nutrition was not administered according to the all-in-one principle. Because of its beneficial effects on the gastrointestinal tract, enteral nutrition alone replaced parenteral nutrition as the gold standard of nutritional care in the ICU in the 1980s. However, enteral nutrition alone is frequently associated with insufficient coverage of the energy requirements, and subsequent protein-energy deficit is correlated with a worse clinical outcome. Recent evidence suggests that all-in-one parenteral nutrition has no significant effect on mortality and infectious morbidity in patients in the ICU if a glycemic control is obtained and hyperalimentation avoided. Thus, the time has come to reconsider the use of parenteral nutrition in the ICU. Supplemental parenteral nutrition could prevent onset of nutritional deficiencies when enteral nutrition is insufficient in meeting energy requirements. Clinical studies are warranted to show that the combination of parenteral and enteral nutrition could improve the clinical outcome of patients in the ICU.

Abstract
PURPOSE OF REVIEW In the setting of ICU, the characteristics of patients have changed during the last decade. Patients are older, frequently overweight or obese, present with more chronic diseases and undernutrition. These conditions are characterized by reduced muscle mass and vulnerable homeostasis. This review sustains the hypothesis that an early and optimal nutritional support, combining enteral and parenteral nutrition, could improve the clinical outcome of ICU patients. RECENT FINDINGS The combination of stress and undernutrition observed in the ICUs is associated with negative energy balance, which leads to lean body mass loss. Catabolism of lean body mass has been repeatedly associated with a worsening of the clinical outcome, increased length of hospital stay, recovery and healthcare costs. Early enteral nutrition is the recommended feeding route in ICU patients, but it is often unable to fully cover the nutritional needs. Parenteral nutrition is recommended if enteral nutrition is not feasible. SUMMARY It is hypothesized that supplemental parenteral nutrition, together with insufficient enteral nutrition, could optimize the nutritional therapy by preventing the onset of early energy deficiency, and thus, could allow to reduce the side-effects of undernutrition and promote better chances of recovery after the ICU stay.

Abstract
Background Energy deficit is a common and serious problem in intensive care units and is associated with increased rates of complications, length of stay, and mortality. Parenteral nutrition (PN), either alone or in combination with enteral nutrition, can improve nutrient delivery to critically ill patients. Lipids provide a key source of calories within PN formulations, preventing or correcting energy deficits and improving outcomes. Discussion In this article, we review the role of parenteral lipid emulsions (LEs) in the management of critically ill patients and highlight important biologic activities associated with lipids. Soybean-oil-based LEs with high contents of polyunsaturated fatty acids (PUFA) were the first widely used formulations in the intensive care setting. However, they may be associated with increased rates of infection and lipid peroxidation, which can exacerbate oxidative stress. More recently developed parenteral LEs employ partial substitution of soybean oil with oils providing medium-chain triglycerides, ω-9 monounsaturated fatty acids or ω-3 PUFA. Many of these LEs have demonstrated reduced effects on oxidative stress, immune responses, and inflammation. However, the effects of these LEs on clinical outcomes have not been extensively evaluated. Conclusions Ongoing research using adequately designed and well-controlled studies that characterize the biologic properties of LEs should assist clinicians in selecting LEs within the critical care setting. Prescription of PN containing LEs should be based on available clinical data, while considering the individual patient’s physiologic profile and therapeutic requirements.

Abstract
To assess energy balance in very sick medical patients requiring prolonged acute mechanical ventilation and its possible impact on outcome, we conducted an observational study of the first 14 d of intensive care unit (ICU) stay in thirty-eight consecutive adult patients intubated at least 7 d. Exclusive enteral nutrition (EN) was started within 24 h of ICU admission and progressively increased, in absence of gastrointestinal intolerance, to the recommended energy of 125.5 kJ/kg per d. Calculated energy balance was defined as energy delivered - resting energy expenditure estimated by a predictive method based on static and dynamic biometric parameters. Mean energy balance was - 5439 (sem 222) kJ per d. EN was interrupted 23 % of the time and situations limiting feeding administration reached 64 % of survey time. ICU mortality was 72 %. Non-survivors had higher mean energy deficit than ICU survivors (P = 0.004). Multivariate analysis identified mean energy deficit as independently associated with ICU death (P = 0.02). Higher ICU mortality was observed with higher energy deficit (P = 0.003 comparing quartiles). Using receiver operating characteristic curve analysis, the best deficit threshold for predicting ICU mortality was 5021 kJ per d. Kaplan-Meier analysis showed that patients with mean energy deficit > or =5021 kJ per d had a higher ICU mortality rate than patients with lower mean energy deficit after the 14th ICU day (P = 0.01). The study suggests that large negative energy balance seems to be an independent determinant of ICU mortality in a very sick medical population requiring prolonged acute mechanical ventilation, especially when energy deficit exceeds 5021 kJ per d.

Abstract
Because of their anatomic position in the closed thoracic cavity, the heart and lungs interact during each ventilation cycle. The application of mechanical ventilation and subsequent removal changes normal ventilatory mechanics and produces alterations in cardiac preload and afterload that influence global hemodynamic state and delivery of oxygen and nutrients. Adverse cardiovascular responses to mechanical ventilation and weaning from ventilation include hemodynamic alterations and instability, myocardial ischemia, autonomic dysfunction, and cardiac dysrhythmias. Clinicians must have a clear understanding of the cardiovascular effects of mechanical ventilation and weaning so they may anticipate, recognize, and effectively manage negative effects and improve patient outcomes.

Abstract
Hypermetabolism and malnourishment are common in the intensive care unit. Malnutrition is associated with increased morbidity and mortality, and most intensive care unit patients receive specialized nutrition therapy to attenuate the effects of malnourishment. However, the optimal amount of energy to deliver is unknown, with some studies suggesting that full calorie feeding improves clinical outcomes but other studies concluding that caloric intake may not be important in determining outcome. In this narrative review, we discuss the studies of critically ill patients that examine the relationship between dose of nutrition and clinically important outcomes. Observational studies suggest that achieving targeted caloric intake might not be necessary since provision of approximately 25% to 66% of goal calories may be sufficient. Randomized controlled trials comparing early aggressive use of enteral nutrition compared with delayed, less aggressive use of enteral nutrition suggest that providing increased calories with early, aggressive enteral nutrition is associated with improved clinical outcomes. However, energy provision with parenteral nutrition, either instead of or supplemental to enteral nutrition, does not offer additional benefits. In summary, the optimal amount of calories to provide critically ill patients is unclear given the limitations of the existing data. However, evidence suggests that improving adequacy of enteral nutrition by moving intake closer to goal calories might be associated with a clinical benefit. There is no role for supplemental parenteral nutrition to increase caloric delivery in the early phase of critical illness. Further high-quality evidence from randomized trials investigating the optimal amount of energy intake in intensive care unit patients is needed.

Abstract
BACKGROUND Energy imbalance in critically ill, mechanically ventilated patients may lead to medical complications. The nutrition care team needs accurate, noninvasive, rapid methods to estimate energy requirements. We investigated whether brief measurements of indirect calorimetry at any time of the day would give valid estimates of 24-hour energy expenditure (EE). METHODS EE of 12 mechanically ventilated critically ill patients (6 men, 6 women, mean +/- SD age 67 +/- 18 years, weight 70.2 +/- 8.8 kg) was recorded every minute during 24 hours by indirect calorimetry. All patients were continuously fed enteral nutrition. RESULTS Mean +/- SD EE was 1658 +/- 279 kcal/d (6941 +/- 1167 kJ/d). Within patients, EE during the day fluctuated by 234 kcal in the most constant patient to 1190 kcal in the least constant patient, with a mean fluctuation of 521 kcal (12 patients). No statistically significant difference (p = .53) in mean EE between morning (6-12 hours, 1676 kcal), afternoon (12-18 hours, 1642 kcal), evening (18-24 hours, 1658 kcal), and night (0-6 hours, 1655 kcal) was found. A 2-hour instead of a 24-hour measurement resulted in a maximal error of 128 kcal (536 kJ), which was <10% of the average EE. The maximal error decreased with longer time intervals. CONCLUSIONS In mechanically ventilated critically ill patients, 24-hour indirect calorimetry measurements can be replaced by shorter (>/=2 hours) measurements. Time of day did not affect EE.

Abstract
BACKGROUND & AIMS A wide variation in 24h energy expenditure has been demonstrated previously in intensive care unit (ICU) patients. The accuracy of equations used to predict energy expenditure in critically ill patients is frequently compared with single or short-duration indirect calorimetry measurements, which may not represent the total energy expenditure (TEE) of these patients. To take into account this variability in energy expenditure, estimates have been compared with continuous indirect calorimetry measurements. METHODS Continuous (24h/day for 5 days) indirect calorimetry measurements were made in patients requiring mechanical ventilation for 5 days. The Harris-Benedict, Schofield and Ireton-Jones equations and the American College of Chest Physicians recommendation of 25 kcal/kg/day were used to estimate energy requirements. RESULTS A total of 192 days of measurements, in 27 patients, were available for comparison with the different equations. Agreement between the equations and measured values was poor. The Harris-Benedict, Schofield and ACCP equations provided more estimates (66%, 66% and 65%, respectively) within 80% and 110% of TEE values. However, each of these equations would have resulted in clinically significant underfeeding (<80% of TEE) in 16%, 15% and 22% of patients, respectively, and overfeeding (>110% of TEE) in 18%, 19% and 13% of patients, respectively. CONCLUSIONS Limits of agreement between the different equations and TEE values were unacceptably wide. Prediction equations may result in significant under or overfeeding in the clinical setting.

Abstract
The aim of this study was to evaluate the effect of nutritional deprivation (ND) on signal transduction pathways influencing the translational apparatus in the diaphragm muscle. Male rats were divided into two groups: 1) 20% of usual food intake for 4 days (ND) with water provided at libitum and 2) free-eating control (Ctl). Total protein and RNA were extracted from the diaphragm. Insulin-like growth factor I mRNA was analyzed by RT-PCR. Protein analyses of key cytoplasmic proteins for three signaling pathways deemed important in influencing protein turnover [phosphatidylinositol 3-kinase- Akt-mammalian target of rapamycin, P13K/Akt/glycogen synthase kinase (GSK)-3, and MAPK-ERK] were performed by Western blot. Body weight decreased 30% in ND and increased 17% in Ctl animals. Diaphragm mass decreased 29% in ND animals. Muscle insulin-like growth factor I mRNA abundance was reduced 63% in ND animals. ND resulted in a 55% reduction in phosphorylated (Ser473) Akt. Phosphorylation of mammalian target of rapamycin at Ser2448 was reduced by 85% in ND animals. Downstream effectors important in translation initiation were also affected by ND. Phosphorylated (Thr389) 70-kDa ribosomal protein S6 kinase was significantly reduced (35%) by ND. ND also resulted in significant dephosphorylation of the translational repressor initiation factor 4E-binding protein 1. Phosphorylation of GSK-3alpha (Ser21) and GSK-3beta (Ser9) was increased 55 and 45%, respectively, with ND. Phosphorylation of ERK1 (Thr202) and ERK2 (Tyr204), p44 and p42, respectively, was reduced 64 and 55%, respectively, with ND. Total protein concentration for all signaling intermediates of the three pathways was preserved. We conclude that short-term ND altered the phosphorylation states of key proteins of several pathways involved in protein turnover. This forms the framework for future studies aimed at identifying therapeutic targets in the management of short-term nutritionally induced cachectic states.

Abstract
INTRODUCTION In critically ill patients enteral nutrition (EN) is frequently associated with underfeeding and intolerance, whilst parenteral nutrition (PN) has been associated with a greater risk of infectious complications and overfeeding. MATERIALS AND METHODS The adequacy of nutritional support provided to critically ill patients was prospectively recorded and compared with estimated requirements. The incidence of, and practices contributing to, under- (<80% of energy requirements) and overfeeding (>110% of energy requirements) were identified. RESULTS Overall patients received approximately 81% and 76% of prescribed energy and protein intakes respectively. Underfeeding occurred on 50.3% of days. Reasons for patients failing to achieve adequate intakes included, fasting for airway management procedures (21%) and gastrointestinal intolerance (14%). Overfeeding, although less common (18.6% of days), was more likely to occur in patients with a tracheostomy requiring prolonged mechanical ventilation (>16 days). The combination of oral and nasogastric feeding or use of nutrient-dense feeds were most frequently associated with overfeeding. Discussion The overall adequacy of nutritional intakes in the present study was similar to those reported elsewhere. However, the incidence of overfeeding was greater than anticipated and occurred in patients already experiencing delayed weaning from mechanical ventilation.

Abstract
OBJECTIVE Nutritional support is part of the standard of care for the critically ill adult patient. In the average patient in the intensive care unit who has no contraindications to enteral nutrition (EN) or parenteral nutrition (PN), the choice of route for nutritional support may be influenced by several factors. Because EN and PN are associated with risks and benefits, we systematically reviewed and critically appraised the literature to compare EN with PN the critically ill patient. METHODS We searched computerized bibliographic databases, personal files, and relevant reference lists to identify potentially eligible studies. Only randomized clinical trials that compared EN with PN in critically ill patients with respect to clinically important outcomes were included in this review. In an independent fashion, relevant data on the methodology and outcomes of primary studies were abstracted in duplicate. The studies were subsequently aggregated statistically. RESULTS There were 13 studies that met the inclusion criteria and, hence, were included in our meta-analysis. The use of EN as opposed to PN was associated with a significant decrease in infectious complications (relative risk = 0.64, 95% confidence interval = 0.47 to 0.87, P = 0.004) but not with any difference in mortality rate (relative risk = 1.08, 95% confidence interval = 0.70 to 1.65, P = 0.7). There was no difference in the number of days on a ventilator or length of stay in the hospital between groups receiving EN or PN (Standardized Mean Difference [SMD] = 0.07, 95% confidence interval = -0.2 to 0.33, P = 0.6). PN was associated with a higher incidence of hyperglycemia. Data that compared days on a ventilator and the development of diarrhea in patients who received EN versus PN were inconclusive. In the EN and PN groups, complications with enteral and parenteral access were seen. Four studies documented cost savings with EN as opposed to PN. CONCLUSION The use of EN as opposed to PN results in an important decrease in the incidence of infectious complications in the critically ill and may be less costly. EN should be the first choice for nutritional support in the critically ill.

Abstract
OBJECTIVE A combination of enteral (EN) and parenteral nutrition (PN) is often used as a strategy to optimize nutritional intake in critically ill patients; however, the effects of this intervention on clinically important outcomes have not been widely studied. This paper systematically reviewed studies that compare EN + PN to enteral nutrition (EN) alone in critically ill patients. METHODS We searched bibliographic databases, personal files, and relevant reference lists to identify randomized controlled trials that compared combination EN + PN to EN alone. RESULTS Only five studies met the inclusion criteria. In all these studies PN was started at the same time as EN in the experimental group. When the results of these trials were aggregated, EN + PN had no significant effect on mortality. There was no difference between the two groups in rates of infectious complications, length of hospital stay, or ventilator days. CONCLUSIONS In critically ill patients who are not malnourished and have an intact gastrointestinal tract, starting PN at the same time as EN provides no benefit in clinical outcomes over EN alone. More research is needed to determine the effects of combination EN + PN on clinical outcomes in critically ill patients who are poorly intolerant to EN.

Abstract
PURPOSE OF REVIEW This review analyses the recently published literature focusing on nutritional assessment in intensive care unit patients. The metabolic response to nutritional intervention is difficult to evaluate in critically ill patients whose body weight is influenced largely by massive fluid administration or losses. Visceral protein plasma levels have been proposed for this purpose, because they reflect hepatic synthesis in response to nutrient supply. However, in acute inflammatory states, liver activity is converted to the synthesis of acute-phase response proteins, resulting in a dramatic drop in visceral proteins, despite nutritional support. RECENT FINDINGS The data regarding visceral protein levels were examined in relation to nutritional supplementation, and compared with other nutritional parameters and clinical outcomes. Transthyretin and retinol-binding protein levels seem to be the most sensitive to nutritional intervention. They are also the earliest to rise at the decrease of acute-phase protein levels, therefore representing a good index of the reversing reprioritization of hepatic protein synthesis. An inconsistent relationship was found between visceral protein plasma levels and clinical outcome in intensive care unit patients, probably because of the difficulty in demonstrating clearly a beneficial effect of nutritional supplementation in highly catabolic conditions. SUMMARY In the acute stage of critical illness, the bi-weekly measurement of transthyretin together with acute-phase response protein plasma levels seems to be a 'window' on the metabolic condition (anabolism versus catabolism). However, only in the presence of stable inflammatory parameters do transthyretin levels reflect the adequacy of nutritional coverage.

[PMID: 12974978 PMCID: PMC270724 DOI: 10.1186/cc2366] [Citation(s) in RCA: 32] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2003] [Revised: 08/05/2003] [Accepted: 08/05/2003] [Indexed: 01/15/2023] Open
Abstract
BACKGROUND There is very little information on what is considered an adequate energy intake for mechanically ventilated, critically ill patients. The purpose of the present study was to determine this energy requirement by making use of patients' nutritional status. METHODS The study was conducted in a multidisciplinary intensive care unit of Taichung Veterans General Hospital, Taiwan. Patients were hemodynamically stable and not comatose, and were requiring at least 7 days of mechanical ventilation. Fifty-four patients successfully completed this study. The resting energy expenditure was measured using indirect calorimetry. The total energy requirement was considered 120% of the measured energy expenditure. The daily nutrient intake was recorded. Nutritional status was assessed using single and multiple parameters, nitrogen balance, and medical records, and was performed within 24 hours of admission and after 7 days in the intensive care unit. RESULTS Fifteen patients were being underfed (<90% of total energy requirement), 20 patients were in the appropriate feeding (AF) group (within +/- 10% of total energy requirement), and 19 patients received overfeeding (>110% of total energy requirement). Patients in the underfeeding group received only 68.3% of their energy requirement, while the overfeeding group patients received up to 136.5% of their required calories. Only patients in the AF group had a positive nitrogen balance (0.04 +/- 5.1) on day 7. AF group patients had a significantly higher Nutritional Risk Index value at day 7 than at day 1. CONCLUSION AF patients had more improvement in nutritional status than patients in the other feeding groups. To provide at least 120% of the resting energy expenditure seemed adequate to meet the caloric energy needs of hemodynamically stable, mechanically ventilated, critically ill patients.

Huang YC, Lan PH, Cheng CH, Lee BJ, Kan MN. Vitamin B6 intakes and status of mechanically ventilated critically ill patients in Taiwan. Eur J Clin Nutr 2002; 56:387-92. [PMID: 12001008 DOI: 10.1038/sj.ejcn.1601321] [Citation(s) in RCA: 14] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2001] [Revised: 07/31/2001] [Accepted: 08/01/2001] [Indexed: 01/15/2023]
Abstract
OBJECTIVE To assess vitamin B6 intake and status of critically ill patients. The relationship between vitamin B6 status indicators and the severity of illness and outcome in these patients was also examined. DESIGN Prospective clinical study. SETTING The study was performed at the Taichung Veteran General Hospital, in the central part of Taiwan. SUBJECTS Ninety-four patients in the intensive care unit (ICU) entered the study and 46 patients successfully completed this study. INTERVENTIONS No intervention. MAIN OUTCOME MEASURES Vitamin B6 intake was recorded for 14 days. Vitamin B6 status was assessed by direct measures (plasma pyridoxal 5'-phosphate (PLP), pyridoxal (PL), and urinary 4-pyridoxic acid (4-PA)) and indirect measures (erythrocyte alanine (EALT-AC) and aspartate (EAST-AC) aminotransaminase activity coefficient). The severity of illness (APACHE II score), the length of ventilation dependency, and the length of ICU and hospital stay were recorded. RESULTS Patients had an adequate mean vitamin B6 intake (16.26+/-19.39 mg) during the 14 day study. Mean vitamin B6 intake was significantly higher on day 14 than on day 1 (P<0.001). However, plasma PLP and PL concentrations significantly decreased at the 14th day after admission (P<0.05). Erythrocyte alanine aminotransaminase activity coefficient and EAST-AC did not change significantly. Urinary 4-PA significantly increased at the 14th day (P<0.001). No significant relationships were found between APACHE II scores and clinical outcomes (the length of ICU and hospital stay, the length of ventilation dependency) of patients, vitamin B6 intake or status indicators. CONCLUSIONS Critically ill patients received nutritional support in the ICU, and had sufficient mean vitamin B6 intake and adequate vitamin B6 status. Therefore, the severity of illness and the results should not be affected by vitamin B6 status. However, we have noted that plasma PLP and PL concentrations significantly decreased while vitamin B6 intake significantly increased on day 14. Critical clinical conditions and complex metabolism in the critically ill may account for the reduction of plasma PLP and PL. Since vitamin B6 deficiency causes profound effects on immune system function, dietary or supplemented vitamin B6 intake is suggested for hospitalized patients.
