Sepsis and artificial nutrition

INTRODUCTION: Oedema is observed frequently following surgery and may be associated with worse outcomes. To date, no study has investigated the role of oedema in the emergency surgical patient. This study assesses the incidence of oedema following emergency abdominal surgery and the value of early postoperative oedema measurement in predicting clinical outcome. METHODS: A prospective cohort study of patients undergoing emergency abdominal surgery at a university unit over a two-month period was undertaken...

INTRODUCTION: We previously reported that in artificially-fed critically ill patients, adipose tissue reveals an increase in small adipocytes and accumulation of M2-macrophages. We hypothesized that nutrient-independent factors of critical illness explain these findings, and that the M2-macrophage accumulation may not be limited to adipose tissue. METHODS: In a long-term cecal ligation and puncture (CLP) mouse model of sepsis, we compared the effect of parenteral nutrition (CLP-fed, n = 13) with nutrient restriction (CLP-restricted, n = 11) on body composition, adipocyte size and macrophage accumulation in adipose tissue, liver and lungs...

Sepsis is a serious worldwide health care condition that is associated with high mortality rates, despite improvements in the ability to manage infection. New guidelines for the management of sepsis were recently released that advocate for implementation of care based on evidence-based practice for both adult and pediatric patients. Critical care nurses are directly involved in the assessment of patients at risk for developing sepsis and in the treatment of patients with sepsis and can, therefore, affect outcomes for critically ill patients...

INTRODUCTION: The optimal nutritional strategy remains controversial, particularly in severely septic patients. Our aim was to analyze the effect of three nutritional strategies--enteral (EN), parenteral (PN), and combined nutrition (EN+PN)--on the outcome of patients with severe sepsis or septic shock. PATIENTS AND METHODS: This secondary analysis of the prospective, randomized-controlled, multicenter "Intensive Insulin Therapy and Pentastarch Resuscitation in Severe Sepsis (VISEP)" trial only included patients with a length of stay in the intensive care unit (ICU) of more than 7 days...

Optimised home parenteral nutrition is still, after 35 years of progress, the "gold standard "for benign but chronic intestinal failure. better recognition of chronic intestinal failure, in its multiple facets, is needed to improve Home Parenteral Nutrition by adding associated treatments such as intestinal trophic factors, rehabilitative surgery (reestablishment of colonic continuity, reverse jejunal segment in severe short gut type II) and/or reconstructive surgery (intestinal transplantation for end-stage intestinal failure)...

Health care-induced diseases constitute a fast-increasing problem. Just one type of these health care-associated infections (HCAI) constitutes the fourth leading cause of death in Western countries. About 25 million individuals worldwide are estimated each year to undergo major surgery, of which approximately 3 million will never return home from the hospital. Furthermore, the quality of life is reported to be significantly impaired for the rest of the lives of those who, during their hospital stay, suffered life-threatening infections/sepsis...

IMPORTANCE: Monitoring of residual gastric volume is recommended to prevent ventilator-associated pneumonia (VAP) in patients receiving early enteral nutrition. However, studies have challenged the reliability and effectiveness of this measure. OBJECTIVE: To test the hypothesis that the risk of VAP is not increased when residual gastric volume is not monitored compared with routine residual gastric volume monitoring in patients receiving invasive mechanical ventilation and early enteral nutrition...

BACKGROUND: Specialty-trained intensivist involvement in the care of critically ill patients has been associated with improved outcomes; however, the factors contributing to this observation are unknown. We hypothesized that intensivist-led ICU care would result in decreased mortality, length of stay, and rate of deep venous thrombosis/pulmonary embolism along with improved compliance with ICU process measures. STUDY DESIGN: We performed a retrospective review of 847 patients using the October 2008 transition at a regional medical center from an open ICU to a model in which board-certified intensivists assume primary responsibility or co-management of all critically ill patients...

UNLABELLED: Cronobacter are opportunistic food-borne pathogens associated with meningitis, sepsis, and necrotizing enterocolitis. Little attempt has focused on detection of viable cell of Cronobacter spp. in dry aquatic products, which were frequently used for raw materials of infant foods due to high nutrition. In this paper, one-step reverse transcription polymerase chain reaction (RT-PCR) was developed for detection of viable Cronobacter spp. in dry aquatic products. Specificity test indicated that clearly expected amplicon in size 469 bp was amplified from RNA of Cronobacter, but not from RNA of negative controls and DNA of Cronobacter strains...

Intestinal failure (IF) is a condition in which severe intestinal malabsorption mandates artificial nutrition through a parenteral route. Causes of severe protracted IF include short bowel syndrome, congenital diseases of enterocyte development, and severe motility disorders (total or subtotal aganglionosis or chronic intestinal pseudo-obstruction syndrome). IF can result in nutritional failure, defined as the long-term failure to nourish a child by natural or artificial means. Today, IF-associated liver disease is the most common cause of parenteral nutrition (PN) failure, but catheter-related sepsis and extensive vascular thrombosis may also jeopardize the health of those receiving PN...

PURPOSE: The aims of this study were to determine the prevalence of hypophosphatemia and to discuss the clinical implications of hypophosphatemia in critically ill children. MATERIALS AND METHODS: A retrospective review of the medical records of children admitted to the pediatric intensive care unit from December 2006 to December 2007 was conducted. RESULTS: In 60.2% (n = 71) of the patients, any serum phosphorous level at admission and at the third day or seventh day after admission to pediatric intensive care unit was in hypophosphatemic range...

BACKGROUND: Reconstruction of massive contaminated abdominal wall defects associated with enteroatmospheric fistulation represents a technical challenge. An effective technique that allows closure of intestinal fistulas and reconstruction of the abdominal wall, with a good functional and cosmetic result, has yet to be described. The present study is a retrospective review of simultaneous reconstruction of extensive gastrointestinal tract fistulation and large full-thickness abdominal wall defects, using a novel pedicled subtotal thigh flap...

Septic morbidity associated with advanced surgical and medical treatments is unacceptably high, and so is the incidence of complications occurring in connection with acute emergencies such as severe trauma and severe acute pancreatitis. Only considering the US, it will annually affect approximately (app) 300 million (mill) of a population of almost one million inhabitants and cause the death of more than 200,000 patients, making sepsis the tenth most common cause of death in the US. Two major factors affect this, the lifestyle-associated increased weakness of the immune defense systems, but more than this the artificial environment associated with modern treatments such as mechanical ventilation, use of tubes, drains, intravascular lines, artificial nutrition and extensive use of synthetic chemical drugs, methods all known to reduce or eliminate the human microbiota and impair immune functions and increase systemic inflammation...

Acute respiratory distress syndrome manifests as rapidly progressive dyspnea, tachypnea, and hypoxemia. Diagnostic criteria include acute onset, profound hypoxemia, bilateral pulmonary infiltrates, and the absence of left atrial hypertension. Acute respiratory distress syndrome is believed to occur when a pulmonary or extrapulmonary insult causes the release of inflammatory mediators, promoting neutrophil accumulation in the microcirculation of the lung. Neutrophils damage the vascular endothelium and alveolar epithelium, leading to pulmonary edema, hyaline membrane formation, decreased lung compliance, and difficult air exchange...

BACKGROUND: Acute intestinal failure (AIF) is defined as an inability to tolerate 80% of nutritional requirements delivered enterally for a minimum of 48 h. In surgical patients it commonly relates to abdominal sepsis, intestinal obstruction, or ileus. The prevalence of AIF in surgical units in Ireland has not previously been studied. METHODS: We retrospectively audited the general surgical and ICU departments in St James's Hospital over a 3-month period to identify patients with AIF and followed their management and outcomes focusing on the need for artificial nutrition and surgical intervention...

INTRODUCTION: Over 5,000 cases of invasive Candida species infections occur in the United Kingdom each year, and around 40% of these cases occur in critical care units. Invasive fungal disease (IFD) in critically ill patients is associated with increased morbidity and mortality at a cost to both the individual and the National Health Service. In this paper, we report the results of a systematic review performed to identify and summarise the important risk factors derived from published multivariable analyses, risk prediction models and clinical decision rules for IFD in critically ill adult patients to inform the primary data collection for the Fungal Infection Risk Evaluation Study...

Nosocomial sepsis agents with multidrug resistance have led to higher morbidity and mortality in premature infants in the recent years. Acinetobacter baumannii has become a leading cause of nosocomial sepsis in several neonatal intensive care units. In this study, the demographic, clinic, microbiologic characteristics and risk factors of 21 premature infants hospitalized in newborn intensive care unit between January 2010-February 2011 and developed A.baumannii infection, have been evaluated retrospectively...

INTRODUCTION: Severe Guillain-Barré syndrome (GBS) is associated with significant morbidity and also mortality. Identification of modifiable risk factors may help in reducing the morbidity and mortality. OBJECTIVE: To study the prognostic factors in a selected cohort of mechanically ventilated GBS patients. MATERIALS AND METHODS: Case records of GBS patients requiring mechanical ventilation admitted between 1997 and 2007 were analyzed. All patients satisfied the National Institute of Neurological and Communicative Disorders and Stroke (NINCDS) criteria for GBS...

Infant botulism is the most common form of human botulism in Argentina and the United States. BabyBIG (botulism immune globulin intravenous [human]) is the antitoxin of choice for specific treatment of infant botulism in the United States. However, its high cost limits its use in many countries. We report here the effectiveness and safety of equine botulinum antitoxin (EqBA) as an alternative treatment. We conducted an analytical, observational, retrospective, and longitudinal study on cases of infant botulism registered in Mendoza, Argentina, from 1993 to 2007...
