BACKGROUND & AIMS
There are sparse data regarding the rate of catheter salvage and long-term effectiveness of antibiotic lock treatment outcome after central line-associated bloodstream infections (CLABSI). Objectives were to analyze the effectiveness of central venous catheter (CVC) rescue strategy and its impact on catheter lifespan. Secondary objective included effectiveness of taurolidine+4% citrate in primary prevention, compared to a secondary prevention strategy, by analyzing infection incidence during two successive periods.
METHOD
Real-life 5-year observational study assessing CLABSI occurrence and CVC salvage outcomes in adult patients requiring Home Parenteral Nutrition (HPN) managed in a single-center Intestinal Failure Unit.
RESULTS
Over the 5-year period, there were 106 confirmed infections (63/143 patients (44%)). Infection incidence was 0.92/1000 catheter-days. Incidence was 1.02/1000 catheter-days during the taurolidine+4% citrate period while lower at 0.84/1000 catheter-days (p = 0.034) during the systematic taurolidine lock period. Of the total number of infections, 89 CVCs were immediately removed and 17 were salvaged. The success rate of catheter salvage with antibiotic lock was 82.4%, with 53% remaining CLABSI-free at one year. The salvage strategy extended catheter lifespan by a median 165 days (IQR 50-214). However, the rate of new infection was significantly higher in instances of salvage (71.4%) vs. removal (36%). Parenteral Nutrition (PN) ≥12 months (p = 0.002), PN (vs. hydroelectrolytic support) (p = 0.028) and self-management by patients (p = 0.049) were independent risk factors of CLABSI.
CONCLUSION
Catheter salvage appears to be an effective long-term strategy with >50% of CVCs remaining CLABSI-free at one year and a prolonged catheter life, although may expose to a more frequent and earlier infection recurrence.

BACKGROUND & AIMS
Scleroderma is a multi-system disease that causes hardening of connective tissue. The gastrointestinal (GI) tract is affected in 90% of patients, which may cause nutritional decline. Due to the rarity of the disease, current nutritional guidelines in scleroderma are extrapolated from evidence in other chronic diseases. This systematic review examines the effects of oral nutrition supplements (ONS), enteral nutrition (EN) and parenteral nutrition (PN) on both clinical and nutritional outcomes of scleroderma patients.
METHOD
Three separate systematic searches for scleroderma and ONS, EN, and PN were performed. The searches were conducted using EMBASE, PubMed and Web of Science databases.
RESULTS
A total of 9 studies (ONS: 2, EN: 1 and PN: 6) met the inclusion and exclusion criteria and were included in the review. All patients had scleroderma and were malnourished or at risk of malnutrition [weighted average age: 53 years, Body Mass Index (BMI): 19 kg/m]. Artificial nutrition support was shown to be an effective therapy for preventing nutritional decline and reversing malnutrition but had no impact on disease progression. Mean BMI increased with home parenteral nutrition (HPN) and EN, from 15 kg/m to 21.0 kg/m. Weight was maintained with ONS, and sarcopenia decreased. Only HPN positively impacted quality of life and GI symptoms, with complication rates similar to patients with other indications.
CONCLUSION
Scleroderma patients should be routinely screened for malnutrition. Malnutrition is treated in a stepwise manner, starting with ONS, then EN and finally PN, based on GI sufficiency and tolerance of the patient. HPN is an effective therapy for patients with advanced disease and intestinal failure. However, larger, long-term, prospective studies for each nutritional therapy are required to make firm conclusions.

Malnutrition is associated with poor surgical outcomes, and therefore optimizing nutritional status preoperatively is very important. The purpose of this paper is to review the literature related to preoperative parenteral nutrition (PN) and to provide current evidence based guidance. A systemic online search of PubMed, Medline, and Cochrane Databases from January 1990 to February 2020 was done. Sixteen studies were included in this narrative review, including four meta-analyses and twelve clinical trials. The majority of studies have demonstrated benefits of preoperative PN on postoperative outcomes, including reduced postoperative complications (8/10 studies) and postoperative length of stay (3/4 studies). Preoperative PN is indicated in malnourished surgical patients who cannot achieve adequate nutrient intake by oral or enteral nutrition. It can be seen that most studies showing benefits of preoperative PN often included patients with upper gastrointestinal cancer and inflammatory bowel disease (10/12 studies), which gastrointestinal problems are commonly seen and enteral nutrition may be not feasible. When preoperative PN is indicated, adequate energy and protein should be provided, and patients should receive at least seven days of PN prior to surgery. The goal of preoperative PN is not weight regain, but rather repletion of energy, protein, micronutrients, and glycogen stores. Complications associated with preoperative PN are rarely seen in previous studies. In order to prevent and mitigate the potential complications such as refeeding syndrome, optimal monitoring and early management of micronutrient deficiencies is required.

Review
(1) Background: Pancreatic cancer (PaCa) is directly related to malnutrition, cachexia and weight loss. Nutritional interventions (NI) are used in addition to standard therapy. The aim of this systematic review is to provide an overview of the types of NI and their effects. (2) Methods: We included RCTs with at least one intervention group receiving an NI and compared them with a control group with no NI, placebo or alternative treatment on cachexia, malnutrition or weight loss in patients with PaCa. Any available literature until 12 August 2021 was searched in the Pubmed and Cochrane databases. RCTs were sorted according to NI (parenteral nutrition, enteral nutrition, dietary supplements and mixed or special forms). (3) Results: Finally, 26 studies with a total of 2720 patients were included. The potential for bias was mostly moderate to high. Parenteral nutrition is associated with a higher incidence of complications. Enteral nutrition is associated with shorter length of stay in hospital, lower rate and development of complications, positive effects on cytokine rates and lower weight loss. Dietary supplements enriched with omega-3 fatty acids lead to higher body weight and lean body mass. (4) Conclusions: Enteral nutrition and dietary supplements with omega-3 fatty acids should be preferred in nutritional therapy of PaCa patients.

Meta-Analysis
BACKGROUND
The need for nutritional support following pancreaticoduodenectomy is well recognised due to the high prevalence of malnutrition, but the optimal delivery route is still debated. This meta-analysis evaluated postoperative outcomes in patients receiving enteral or parenteral nutrition.
METHODS
EMBASE, MEDLINE and Cochrane databases were searched to identify randomised controlled trials comparing enteral and parenteral nutrition in patients undergoing pancreaticoduodenectomy. The primary outcome measure was delayed gastric emptying (DGE). Secondary outcome measures included length of hospital stay (LOS); postoperative pancreatic fistula (POPF); post-pancreaticoduodenectomy haemorrhage (PPH); and infective complications (IC).
RESULTS
Five randomised controlled trials met inclusion criteria and reported on 690 patients (enteral nutrition n = 383; and parenteral nutrition n = 307). Median age was 61.5 years (interquartile range 60.1-63.6). The pooled relative risk (RR) of the primary outcome, DGE, was 0.97 (95% confidence interval (CI) 0.52-1.81, p = 0.93). There were no statistically significant difference in the secondary outcome measures of POPF (RR 1.07, 95% CI 0.42-2.76, p = 0.88); PPH (RR 0.67, 95% CI 0.31-1.48, p = 0.33) and infectious complications (RR 0.76, 95% CI 0.50-1.17, p = 0.22). However, LOS favoured enteral nutrition, weighted mean difference -1.63 days (95% CI -2.80, -0.46, p = 0.006).
CONCLUSIONS
EN is associated with a significantly shorter LOS compared to PN in patients undergoing pancreaticoduodenectomy.

Review
Supplemental parenteral nutrition (SPN) is used in a step-up approach when full enteral support is contraindicated or fails to reach caloric targets. Recent nutrition guidelines present divergent advices regarding timing of SPN in critically ill patients ranging from early SPN (<48 h after admission; EPN) to postponing initiation of SPN until day 8 after Intensive Care Unit (ICU) admission (LPN). This systematic review summarizes results of prospective studies among adult ICU patients addressing the best timing of (supplemental) parenteral nutrition (S)PN. A structured PubMed search was conducted to identify eligible articles. Articles were screened and selected using predetermined criteria and appraised for relevance and validity. After critical appraisal, four randomized controlled trials (RCTs) and two prospective observational studies remained. One RCT found a higher percentage of alive discharge from the ICU at day 8 in the LPN group compared to EPN group (p = 0.007) but no differences in ICU and in-hospital mortality. None of the other RCTs found differences in ICU or in-hospital mortality rates. Contradicting or divergent results on other secondary outcomes were found for ICU length of stay, hospital length of stay, infection rates, nutrition targets, duration of mechanical ventilation, glucose control, duration of renal replacement therapy, muscle wasting and fat loss. Although the heterogeneity in quality and design of relevant studies precludes firm conclusions, it is reasonable to assume that in adult critically ill patients, there are no clinically relevant benefits of EPN compared with LPN with respect to morbidity or mortality end points, when full enteral support is contraindicated or fails to reach caloric targets. However, considering that infectious morbidity and resolution of organ failure may be negatively affected through mechanisms not yet clearly understood and acquisition costs of parenteral nutrition are higher, the early administration of parenteral nutrition cannot be recommended.

BACKGROUND
Low microbial diversity or altered microbiota composition is associated with many disease states. In the treatment of many conditions, enteral (EN) or parenteral (PN) nutrition is frequently required.
OBJECTIVE
This systematic review aimed to identify and evaluate the evidence of the effect of EN vs PN on the gastrointestinal microbiota.
METHOD
A comprehensive systematic literature search of 5 databases was completed to review studies published until February 2020. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were utilized in completion of the review with the Academy of Nutrition and Dietetics quality criteria checklist and Grading of Recommendations Assessment, Development and Evaluation to evaluate the included studies. The review was registered on PROSPERO (CRD42018091328). Studies were eligible for inclusion if participants were older than 3 years, patients received either EN, PN or both, with some patients receiving each mode of nutrition support. The main outcome was any assessment of the gastrointestinal microbiota, including diversity or taxa abundance.
RESULTS
Eleven articles (n = 367 patients) met the inclusion criteria and were evaluated. Seven studies (n = 237) reported greater abundance of Proteobacteria with the provision of PN compared to EN; 6 studies (n = 172) reported lower Firmicutes and 5 studies (n = 155) lower Bacteroidetes. In 7 studies (n = 282), microbial diversity was lower with provision of PN than EN. The Grading of Recommendations Assessment, Development and Evaluation certainty of evidence was very low.
CONCLUSIONS
Provision of PN may lead to greater abundance of Proteobacteria and reduced microbial diversity; however, there is limited literature on this topic and additional research is warranted to improve understanding of the impact of EN vs PN on the microbiota.

Meta-Analysis
OBJECTIVE
To assess the physiological outcomes and interpersonal influences that should be considered when making the decision to provide artificial nutrition and hydration (AN&H) for patients in hospice/palliative programs.
METHODS
A systematic review was conducted using items from the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols 2015 checklist. Distinct search strategies were employed to find primary research articles that addressed: General health outcomes of artificial nutrition and hydration interventions and nutrition therapy interventions (n = 16), nutrition-related symptoms in end-of-life care (n = 8), and the attitudes of patients and providers toward artificial nutrition and hydration (n = 21).
RESULTS
The effect of AN&H on health outcomes, quality-of-life measures and nutrition-related symptoms is limited and may vary by patient setting and diagnosis. In the absence of consistent evidence for specific health outcomes, decisions regarding AN&H should be made in context of the desires and beliefs of a patient, their family, and their medical providers. These beliefs may not be consistent with likely outcomes or may be inconsistent between individuals involved in the decision-making process, and individuals of different cultures or geographic regions may approach AN&H decisions from different perspectives. To help navigate the intersection of nutrition-related health outcomes and patient/provider beliefs, palliative care teams may employ a variety of strategies for approaching the decision-making process, and may benefit from specific involvement of a Registered Dietitian to help contribute to or lead these discussions.

Review
BACKGROUND
Central venous access devices (CVADs) are used for parenteral nutrition (PN) delivery. We systematically reviewed research-based publications that reported comparative rates of catheter-related bloodstream infection (CRBSI) in patients with CVADs who received PN vs those who did not receive PN therapy.
MATERIALS AND METHODS
The literature search included the Cochrane Library, MEDLINE, CINAHL, and PubMed up to July 14, 2015, to identity studies that compared patients with a CVAD who did and did not have PN therapy.
RESULTS
Eleven observational studies were identified, comprising 2854 participants with 6287 CVADs. Six studies produced significant results in favor of non-PN, 4 studies showed no evidence of a difference between PN and non-PN, and 1 study produced significant results in favor of PN when analyzed per patient with multiple CVADs. Incidence ranged from 0 to 6.6 CRBSIs per 1000 CVAD days in the PN patients and 0.39 to 3.6 CRBSIs per 1000 CVAD days in the non-PN patients. The Cochrane risk of bias assessment tool for nonrandomized studies of interventions was used. Eight studies were rated as moderate risk of bias, 2 as serious, and 1 as critical.
CONCLUSION
The data presented in this systematic review are not sufficient to establish whether patients receiving PN are more at risk of developing CRBSI than those who do not. Future PN studies needs to adjust for baseline imbalances and improve quality and reporting.

Hypersensitivity to the components of parenteral nutrition (PN) is a rare but important complication of PN. We performed a systematic review of hypersensitivity to PN to enable us to build an approach to the individual patient who presents with PN hypersensitivity. A systematic literature search was performed in Ovid Medline, CINAHL, Scopus, and Web of Science using terms for "hypersensitivity" AND "parenteral nutrition" and relevant synonyms. A total of 28 articles were analyzed, and 33 hypersensitivities to PN or components of PN were reported in these 28 articles. Reports of hypersensitivity and subsequent conclusions were based on the clinical observations made by each reporting author. These reactions were evenly split between pediatric and adult patients. Hypersensitivity to PN occurred on day of starting PN in 60.6% patients and after that time in 36.3% patients (range: 1-21 days). Of the hypersensitivities that occurred on day 1 of PN, 70% occurred in the first 30 minutes of initiation of PN. Cutaneous manifestations were the most common, followed by anaphylaxis, respiratory symptoms, and hemodynamic instability. The components most frequently identified as allergens were intravenous fat emulsion (48.4%), multivitamin solution (33.3%), and amino acid solution (9%). Based on this review, an algorithm was created to guide the practitioner on management of PN after the occurrence of such a reaction.
