RESUMEN

Individual personality refers to the Ego and the interpersonal sector. The Ego corresponds to consciousness and self-esteem, including the capacities for emotional self-regulation, self-control, self-evaluation, and self-direction in relation to personal goals. When neoplastic and psychiatric diseases coexist, a patient's quality of life is significantly impacted. While there are somatic differences in disease progression, how the illness is perceived and mainly experienced depends on personality traits. In this study, we administered the DECAS Personality Inventory (a Romanian-validated instrument based on the Five-Factor model of personality) to a group of 121 patients diagnosed with breast cancer to explore the relationships among their personality traits. Descriptive statistics revealed that the mean T scores for openness, extroversion, and emotional stability were low, while the scores for conscientiousness and agreeableness were at an average level. Our findings suggest that, in the studied group, low levels of emotional stability, extroversion, and openness were unfavorable personality dimensions that should be a primary focus of therapeutic strategies, as they significantly affect the quality of life in patients with breast cancer.

RESUMEN

BACKGROUND: Early nutritional challenges can lead to permanent metabolic changes, increasing risk for developing chronic diseases later in life. Total parenteral nutrition (TPN) is a life-saving nutrition regimen, used especially in intrauterine growth-restricted (IUGR) neonates. Early TPN feeding alters metabolism, but whether these alterations are permanent is unclear. Programmed metabolism is likely caused by epigenetic changes due to imbalances of methyl nutrients. OBJECTIVES: We sought to determine whether feeding TPN in early life would increase the risk of developing dyslipidemia in adulthood and whether supplementing the methyl nutrients betaine and creatine to TPN would prevent this development. We also sought to determine whether IUGR exacerbates the effects of neonatal TPN on lipid metabolism in adulthood. METHODS: Female piglets (n=32, 7 d old) were used in four treatments: 24 normal weight piglets were randomized to sow-fed (SowFed), standard TPN (TPN-control), and TPN with betaine and creatine (TPN-B+C); 8 IUGR piglets were fed control TPN (TPN-IUGR) as a fourth group. After 2 weeks of treatment, all pigs were then fed a standard solid diet. At 8 mo old, central venous catheters were implanted to conduct postprandial fat tolerance tests. RESULTS: Feeding TPN in the neonatal period led to dyslipidemia in adulthood, as indicated by higher postprandial triglyceride (TG) levels in TPN-control (P<0.05), compared to SowFed. IUGR piglets were particularly sensitive to neonatal TPN feeding, as TPN-IUGR piglets developed obesity and dyslipidemia in adulthood, as indicated by greater backfat thickness (P<0.05), higher liver TG (P<0.05), slower postprandial TG clearance (P<0.05), and elevated fasting plasma non-high density lipoprotein (HDL)-cholesterol (P<0.01), and non-esterified fatty acids (NEFA) (P<0.001), compared to TPN-control. CONCLUSIONS: Feeding TPN in early life increases the risk of developing dyslipidemia in adulthood, especially in IUGR neonates; however, methyl nutrient supplementation to TPN did not prevent TPN-induced changes in lipid metabolism.

RESUMEN

The clinical diagnosis of a malignant pleural effusion (MPE) is still based on the detection of tumor cells in the pleural effusion. The question of how to improve the efficiency and accuracy of detecting an MPE still remains. This study explores the use of microfluidic technology to concentrate cells in an MPE and achieved the detection of the cell marker TPN in the microarray capture area. TPN is a mitochondria-specific bio-probe that can identify tumor cells on the basis of differences in the mitochondrial potential. First, we designed a microfluidic chip to analyze its performance. The results show that when the total flow rate of the injected chip was 12 mL/h and the volume ratio of cell separation liquid to cell suspension was 1:1, the target cells (A549, MCF-7, and Hela) were enriched and the purity was improved to 98.7-99.3%. Finally, an MPE from cancer patients was used to detect the chip's ability to isolate and enrich tumor cells. Furthermore, the fluorescent identification of the TPN within the tumor cells was simultaneously achieved on the microfluidic chip. In conclusion, the potential to improve the efficiency of the clinical diagnosis of MPEs is provided by the chip structure and analysis conditions explored in this study.

RESUMEN

Zinc (Zn) is a vital trace element that plays a pivotal role in protein synthesis, cellular growth, and differentiation and is involved as a cofactor of metalloenzymes, performing a wide variety of metabolic, immune, and synthesis roles. Zn is required at all stages of an infant's and child's development, and severe Zn deficiency has been reported to lead to slower physical, cognitive, and sexual growth. Preterm neonates are at a higher risk of developing zinc deficiency for a variety of reasons, including low Zn intake from enteral feeds containing breast milk, relative malabsorption due to immaturity of the gastrointestinal tract with limited absorptive capacity, increased urinary loss of zinc, and increased demand during the early developmental stages. Moreover, premature infants are at risk of gastrointestinal diseases like necrotizing enterocolitis (NEC), which can limit absorption capacity and potentially lead to malabsorption. TPN is frequently used in preterm infants to provide them with sufficient nutrients and calories. However, it has its own complications, including cholestasis, especially if used for prolonged periods. In this case report, we are presenting the case of a male preterm infant who was delivered by caesarean section at 26 weeks' gestation. The baby developed an intestinal perforation due to NEC, for which he underwent surgery for resection of the necrotic bowel and the creation of a high ileal stoma and was put on prolonged total parenteral nutrition (TPN), which led to the development of zinc deficiency.

RESUMEN

TPN672MA, an innovative antipsychotic drug candidate currently in clinical trials, acts as a dopamine D2/D3 receptor partial agonist, serotonin 5-HT1A receptor agonist, and serotonin 5-HT2A receptor antagonist. Preclinical investigations have demonstrated its potential in treating the core symptoms of schizophrenia. The present study highlights TPN672MA's significant antidepressant-like effects in classical behavioral models, such as the chronic social defeat stress paradigm. The pronounced 5-HT1A receptor agonism and D2/D3 receptor partial agonism of TPN672MA likely contribute to its therapeutic effects in depression. Additionally, TPN672MA's antidepressant-like efficacy may be linked to its ability to enhance the expression levels of brain-derived neurotrophic factor (BDNF) and postsynaptic density protein-95 (PSD95) in the hippocampus. Furthermore, TPN672MA displayed a more rapid onset of antidepressant-like action. In conclusion, TPN672MA represents a promising new drug candidate for the treatment of symptoms of schizophrenia and depression.

RESUMEN

Emery-Dreifuss muscular dystrophy (EDMD) is a rare, inherited human disease. Similar to other neuromuscular dystrophies, EDMD is clinically characterized by muscle atrophy and weakness, multi-joint contractures with spine rigidity, and cardiomyopathy. Over time, muscular weakness can lead to dysphagia and a severe lowering of body mass index (BMI), worsening the prognosis. We present the case of a young male patient affected by EDMD, admitted to the hospital for pneumothorax in a severe state of undernourishment. The patient was treated with total parenteral nutrition (TPN) with Smofkabiven®, supplemented with micronutrients (vitamins and trace elements), and with minimal enteral nutrition through food. Within a year, the patient gained 8.5 kg and kept his body weight stable for the 6 years of the follow-up. In this study, we show that TPN ensures the nutritional requirements of EDMD patients in a safe and well-tolerated manner, allowing a considerable and stable improvement in nutritional status, which has a positive impact on the disease itself and the patients' quality of life.

RESUMEN

Syphilis is a sexually transmitted infection (STI) caused by the spiral bacterium Treponema pallidum. Diagnosis is based on epidemiology, clinical and serology, but serodiagnosis is challenging because distinct clinical forms of the infection may influence serological performance. Several recombinant Treponema pallidum-proteins have already been tested for syphilis diagnosis and they are critical to achieve high accuracy in serological testing. A total of 647 samples were included in the study: 180 T. pallidum-positive samples, 191 T. pallidum-negative samples and 276 sera from individuals infected with unrelated diseases. The diagnostic potential was validated by analysis of ROC curves. For the indirect ELISA, TpN17 (100%) and TmpA (99%) showed excellent AUC values. Sensitivity values were 97.2% for TpN17 and 90.6% for TmpA, while specificity was 100% for both molecules. According to the clinical phase, TmpA ranged from 84% to 97%, with the highest value for secondary syphilis. TpN17 was 100% sensitive for the primary and secondary stages and 93.2% for recent latent syphilis. All clinical phases achieved 100% specificity. Accuracy values showed that TmpA (> 95%) and TpN17 (> 98%) presented high diagnostic accuracy for all clinical stages of syphilis. Cross-reactivity was only observed in one sample positive for Chagas disease (1.5%), when TpN17 was evaluated. On the other hand, TmpA showed reactivity for two samples positive for Chagas disease (3.1%), one sample positive for HBV (1.25%), two samples positive for HIV (9.5%) and one sample positive for HTLV (1.6%). The TmpA antigen's performance was evaluated in multiple studies for syphilis diagnosis, corroborating our findings. However, TpN17 sensitivity values have ranged in other studies. According to clinical stages of the infection, our findings obtained close performance values.

RESUMEN

Total Parenteral Nutrition (TPN) is a method of providing nutrients directly into the bloodstream for individuals who are unable to meet their nutritional needs through the normal digestive process or gastrointestinal system. It provides macronutrients and micronutrients in a single container, reducing handling and contamination risks and making it more cost-effective. TPN has the potential to be used as a drug delivery system, with applications in combination therapies, personalized medicine, and integrating advanced technologies. It can enhance drug dosage precision and provide nutritional assistance, potentially reducing hospitalization and improving patient outcomes. However, implementing new applications requires thorough testing and regulatory approval. TPN could be particularly useful in pediatric and geriatric care and could also contribute to global health by combating malnutrition in areas with limited medical resources. Healthcare professionals prepare a sterile solution tailored to each patient's nutritional needs, and administration involves a central venous catheter. However, the simultaneous administration of medications with PN admixtures can result in pharmacological incompatibility, which can impact the stability of the oil-in-water system. The European Society for Clinical Nutrition and Metabolism and the American Society for Parenteral and Enteral Nutrition recommendations advise against including non-nutrient drugs in PN admixtures due to safety concerns. This review focuses on the utilization of Total Parenteral Nutrition (TPN) as a method for delivering drugs. It discusses the benefits and difficulties associated with its commercial application and offers suggestions for future research endeavors.

RESUMEN

Megacystis microcolon intestinal hypoperistalsis syndrome (MMIHS) is an uncommon genetic disorder inherited in an autosomal recessive pattern that affects the muscles that line the bladder and intestines. The most common genes associated with MMIHS mutations are ACTG2, LMOD1, MYH11, MYL9, MYLK, and PDCL3. However, the complete genetic landscape of MMIHS still needs to be fully understood. The diagnosis of MMIHS can be challenging. However, advances in prenatal and diagnostic techniques, such as ultrasound and fetal urine analysis, have improved the ability to detect the syndrome early. Targeted next-generation sequencing (NGS) and other diagnostic tests can also diagnose MMIHS. The management of MMIHS involves addressing severe intestinal dysmotility, which often necessitates total parenteral nutrition (TPN), which can lead to complications such as hepatotoxicity and nutritional deficiencies. Multivisceral and intestinal transplantation has emerged as therapeutic options, offering the potential for improved outcomes and enteral autonomy. Understanding the genetic underpinnings of MMIHS is crucial for personalized care. While the prognosis varies, timely interventions and careful monitoring enhance patient outcomes. Genetic studies have given us valuable insights into the molecular mechanisms of MMIHS. These studies have identified mutations in genes involved in the development and function of smooth muscle cells. They have also shown that MMIHS is associated with defects in the signaling pathways that control muscle contraction. Continued research in the genetics of MMIHS holds promise for unraveling the complexities of MMIHS and improving the lives of affected individuals.

RESUMEN

This case report highlights a concerning and complex case of a middle-aged female presenting with severe malabsorption, diarrhea, and subsequent malnutrition. The patient's weight dramatically dropped from 85 lbs to 50 lbs over the course of two to four months. The medical history included ongoing pancreatitis, esophageal ulcers, and previous surgeries for a dermoid cyst in the brain and cervical neoplasia. Upon admission to the hospital, the patient received total parenteral nutrition (TPN) on the first day, but this led to delirium due to refeeding syndrome. Refeeding syndrome is a well-known condition that can occur when malnourished individuals receive too much nutrition too quickly, causing metabolic imbalances and potentially serious complications. Subsequently, during the second hospitalization, the patient did not receive TPN but was instead administered 5% dextrose with 20 mEq of potassium chloride (KCl). Unfortunately, her condition worsened, leading to multiorgan failure. During the third hospitalization, TPN was reintroduced under consultation and hospitalist evaluation, and the patient's symptoms improved. Overall, this case report outlines a complex case with multiple medical issues, including severe malnutrition, which required careful management and consideration of the patient's unique needs. It underscores the importance of cautious nutritional support for severely malnourished individuals to avoid complications such as refeeding syndrome. The case also emphasizes the value of interdisciplinary collaboration and continuous monitoring to achieve successful outcomes in such complex situations.

RESUMEN

The management of preterm newborns must consider the severe problem of retinopathy of prematurity (ROP). A systematic review has been conducted to effectively acknowledge how enteral and parenteral early nutrition affect the growth and progression of ROP. The study summarizes recent findings from various sources to give insight into the relationship between dietary practices and ROP risks. When untreated, retinopathy of prematurity (ROP) may cause severe vision loss or blindness in premature newborns. The latter two phases of ROP progression are the most serious. A child's early nutrition, both orally and intravenously, significantly impacts the severity and progression of ROP. This systematic review aims to examine the evidence linking early nutrition to ROP in premature infants. The study used Embase, Scopus, and PubMed to conduct our search. ROP, premature newborns, and nutrition were keywords used to find relevant papers. Nine research studies made it through the screening process and offered important information on the impact of diet on ROP. These studies support the idea that poor nutrition is a driving force behind the onset of ROP. The risk of ROP has been associated with postnatal development, hyperglycemia, polyunsaturated fatty acid levels, and the presence of breast milk. The outlook for ROP has also been discovered to be affected by the length of time the patient has received parenteral feeding. The incidence and severity of ROP may be mitigated by providing better nutrition to premature newborns. This comprehensive study concludes that early nutrition, both enteral and parenteral, substantially influences the development and progression of ROP in premature newborns. The significance of nutrition in newborn care is highlighted by the possibility that improved dietary methods might aid in preventing and treating this vision-threatening illness.

RESUMEN

Aims: To systematically evaluate the efficacy and safety of different insulin infusion methods in the treatment of total parenteral nutrition (TPN)-associated hyperglycemia based on published literature and the data of completed clinical trials using a network meta-analysis. Methods: A comprehensive search of PubMed, Elsevier, Web of Science, EMBASE, Medline, clinicaltrials.gov, Cochrane Library, and three Chinese databases (Wanfang Data, China National Knowledge Infrastructure, and SINOMED) up to December 15, 2022, was performed to collect information on different insulin infusion methods used for the treatment of TPN-associated hyperglycemia, and the Cochrane systematic review method was used to screen the literature, evaluate the quality of the included literature, and extract clinical characteristics for a network meta-analysis. Clinical outcomes included mean blood glucose (MBG), hypoglycemia, hospital length of stay, hyperglycemia, surgical site infection (SSI) and mean total daily insulin. Results: A total of 21 articles, including 1,459 patients, were included to analyze 6 different routes of insulin infusion, including continuous intravenous insulin infusion (CVII), continuous subcutaneous insulin infusion (CSII), subcutaneous glargine insulin (s.c. GI), the addition of regular insulin to the PN mixture (RI-in-PN), multiple subcutaneous insulin injections (MSII) and 50% of insulin administered as RI-in-PN + 50% of insulin administered as s.c. GI (50% RI-in-PN + 50% s.c. GI). The results of the network meta-analysis showed that MSII was the least effective in terms of MBG, followed by CVII. The 6 interventions were basically equivalent in terms of the hypoglycemia incidence. In terms of the length of hospital stay, patients in the CVII group had the shortest hospital stay, while the MSII group had the longest. CVII was the best intervention in reducing the incidence of hyperglycemia. The incidence of SSI was the lowest in the CSII and CVII groups, and the mean daily insulin dosage was the lowest in the CVII group. Conclusion: Current literature shows that for the treatment of TPN-associated hyperglycemia, CVII is the most effective, reducing the incidence of hyperglycemia and shortening the length of hospital stay without increasing the incidence of hypoglycemia. MSII has the worst efficacy, leading to a higher MBG and longer hospital stay, and RI-in-PN, CSII, s.c. GI and 50% RI-in-PN + 50% s.c. GI are better in terms of efficacy and safety and can be substituted for each other. Systematic Review Registration: https://www.crd.york.ac.uk/prospero/, identifier CRD42023439290.

RESUMEN

Multiple sclerosis (MS) is one of the most common autoimmune diseases of central nervous system (CNS) demyelination. Experimental autoimmune encephalomyelitis (EAE) is the most classic animal model for simulating the onset of clinical symptoms in MS. Previous research has reported the anti-inflammatory effects of artemisinin on autoimmune diseases. In our study, we identified a novel small molecule, TPN10518, an artemisinin derivative, which plays a protective role on the EAE model. We found that TPN10518 reduced CNS inflammatory cell infiltration and alleviated clinical symptoms of EAE. In addition, TPN10518 downregulated the production of Th1 and Th17 cells in vivo and in vitro, and decrease the levels of related chemokines. RNA-seq assay combined with the experimental results demonstrated that TPN10518 lowered the mRNA and protein levels of the AP1 subunits c-Fos and c-Jun in EAE mice. It was further confirmed that TPN10518 was dependent on AP1 to inhibit the differentiation of Th1 and Th17 cells. The results suggest that TPN10518 reduces the production of Th1 and Th17 cells through inhibition of AP1 to alleviate the severity of EAE disease. It is expected to be a potential drug for the treatment of MS.

RESUMEN

The term chyloperitoneum refers to the accumulation of triglyceride-rich fluid in the peritoneal cavity. It is an uncommon clinical condition that usually occurs due to disruption of lymphatic flow secondary to trauma or obstruction. Common causes include penetrating or blunt trauma, iatrogenic injuries, congenital anomalies, malignant neoplasms, infections such as tuberculosis and filariasis, liver cirrhosis, constrictive pericarditis, congestive heart failure, inflammatory conditions, such as sarcoidosis and pancreatitis, and radiation- and drug-related pathologies. We present a case of chyloperitoneum in a 33-year-old woman secondary to penetrating abdominal trauma secondary to a gunshot wound. The patient was successfully managed with total parenteral nutrition and octreotide administration. To our knowledge, this is the only case of chylous ascites caused by a penetrating injury that has been reported in the literature. Conservative management with the initiation of total parenteral nutrition and octreotide led to the resolution of this condition.

RESUMEN

Personalization of ICU nutrition is essential to future of critical care. Recommendations from American/European guidelines and practice suggestions incorporating recent literature are presented. Low-dose enteral nutrition (EN) or parenteral nutrition (PN) can be started within 48 h of admission. While EN is preferred route of delivery, new data highlight PN can be given safely without increased risk; thus, when early EN is not feasible, provision of isocaloric PN is effective and results in similar outcomes. Indirect calorimetry (IC) measurement of energy expenditure (EE) is recommended by both European/American guidelines after stabilization post-ICU admission. Below-measured EE (~ 70%) targets should be used during early phase and increased to match EE later in stay. Low-dose protein delivery can be used early (~ D1-2) (< 0.8 g/kg/d) and progressed to ≥ 1.2 g/kg/d as patients stabilize, with consideration of avoiding higher protein in unstable patients and in acute kidney injury not on CRRT. Intermittent-feeding schedules hold promise for further research. Clinicians must be aware of delivered energy/protein and what percentage of targets delivered nutrition represents. Computerized nutrition monitoring systems/platforms have become widely available. In patients at risk of micronutrient/vitamin losses (i.e., CRRT), evaluation of micronutrient levels should be considered post-ICU days 5-7 with repletion of deficiencies where indicated. In future, we hope use of muscle monitors such as ultrasound, CT scan, and/or BIA will be utilized to assess nutrition risk and monitor response to nutrition. Use of specialized anabolic nutrients such as HMB, creatine, and leucine to improve strength/muscle mass is promising in other populations and deserves future study. In post-ICU setting, continued use of IC measurement and other muscle measures should be considered to guide nutrition. Research on using rehabilitation interventions such as cardiopulmonary exercise testing (CPET) to guide post-ICU exercise/rehabilitation prescription and using anabolic agents such as testosterone/oxandrolone to promote post-ICU recovery is needed.

RESUMEN

The etiologies of short bowel syndrome (SBS) can be stratified into congenital or acquired etiologies, with the latter being more prevalent. Small intestinal surgical resection is the most common acquired etiology, employed in settings including mesenteric ischemia, intestinal injury, radiation enteritis, and inflammatory bowel disease (IBD) complicated by internal fistulas. We describe a case of a 55-year-old Caucasian male with a history of idiopathic superior mesenteric artery (SMA) ischemia post-SMA placement complicated by recurrent small bowel obstructions. He presented with SMA stent occlusion and infarction, leaving him with 75 cm of post-duodenal small bowel after emergent surgical resection. He was trialed on enteral nutrition and progressed to parenteral nutrition (PN) after failure to thrive. With intensive counseling, his compliance improved, and he was able to briefly maintain adequate nutrition status with supplemental total parenteral nutrition. After a period of being lost to follow-up, he succumbed to complications from untreated SBS. This case highlights the need for intensive nutritional support for patients with short bowel syndrome and awareness of clinical complications.

RESUMEN

BACKGROUND: We recently synthesized a compound in which 5-mercapto-1-methyltetrazole (MM4) was coordinated to tiopronin monovalent (TPN-Au(I)) and reported its cytotoxic activity against human leukemia cells in vitro. OBJECTIVE: We further synthesized other heterocyclic compounds coordinated with TPN-Au(I) and assessed their cytotoxic activity against hepatocellular carcinoma HepG2 and lung cancer cell line H1299 in vitro. METHODS: Seven kinds of compounds were synthesized by introducing a five-membered heterocyclic compound into TPN-Au(I). The number of viable cells was counted by a trypan blue dye exclusion assay. Fluorescence conjugated-Annexin V and propidium iodide were used for the apoptosis analysis. RESULTS: Seven compounds were successfully synthesized. Among these compounds, TPN-Au(I)-MTZ (3- mercapto-1,2,4-triazole), TPN-Au(I)-MMT (2-mercapto-5-methyl-1,3,4-thiadiazole), and TPN-Au(I)-MMTT (2-mercapto-5-methylthio-1,3,4-thiadiazole) effectively suppressed the proliferation and induced apoptosis in HepG2 cells. In addition, TPN-Au(I)-MMTT and TPN-Au(I)-MMT also showed effective cytotoxicity against H1299 cells. CONCLUSION: The present results showed that introduction of some five-membered heterocyclic compounds, especially MMT and MMTT, to TPN-Au(I) improved the cytotoxicity against solid cancer cells.

RESUMEN

INTRODUCTION: Glutamine (GLN) and n-3 polyunsaturated fatty acids (n-3PUFAs) have been shown to potentially possess immune-modulating and disease-modifying properties in experimental and clinical critical illness when given with parenteral nutrition (PN). However, we recently showed in experimental cancer models that combinations of GLN/n-3 PUFA may antagonize benefits of either nutrient alone. Thus, our aim was to explore the effects of PN-containing GLN and n-3PUFA mixed lipid emulsion (MLE) alone and in combination in experimental sepsis. METHODS: Adult male rats were exposed to cecal ligation and puncture (CLP) and sacrificed at 24 h. Rats were infused with either normal saline (NS); PN + Intralipid (PNcont); PN + GLN; PN + n-3PUFA MLE; or PN + GLN/n-3PUFA MLE after CLP-sepsis for 23 h. Animals were assessed at 24 h for sepsis score, Gram (+) and Gram (-) bacterial load in blood, peritoneum, and bronchoalveolar lavage fluid (BALF). RESULTS: Rats treated with PN + GLN or PN + n-3PUFA showed significantly lower sepsis scores compared to NS and PNcont (all p ≤ 0.016). Non-significant trends to improved sepsis scores was observed in rats treated with PN + GLN/n-3PUFA versus NS (p = 0.067) or PNcont (p = 0.093). Rats treated with PN + GLN, PN + n-3PUFA, or PN + GLN/n-3PUFA had significant improvement or trends to improved Gram (+) and Gram (-) bacterial loads in BALF versus NS (p ≤ 0.05, PN + GLN and PN + GLN/n-3PUFA for Gram (+); p = 0.057, PN + n-3PUFA for Gram (+); p ≤ 0.05, n-3PUFA and PN + GLN/n-3PUFA for Gram (-)). No differences between groups in blood or peritoneal bacterial counts observed. CONCLUSIONS: This data describes initial evidence that nutritional-doses of GLN, n-3PUFA MLE, and GLN + n-3PUFA MLE in PN can improve bacterial load/clearance in sepsis. Further, improvements of sepsis score by PN + n-3PUFA MLE and PN + GLN was observed. Previously observed antagonism of benefits of PN-containing GLN or n-3PUFAs alone by combinations of these nutrients was not observed in experimental sepsis. These results suggest further research is needed into PN-strategies using GLN and/or n-3PUFA at nutritional-doses in sepsis.

RESUMEN

Total parenteral nutrition (TPN) is the intravenous delivery of nutrients and is commonly used in the Neonatal Intensive Care Unit (NICU). Hypersensitivity reactions to parenteral nutrition have seldom been described in the literature. Anaphylaxis is a potentially life-threatening emergency condition that can progress rapidly and involves multiple organ systems. We report a case of anaphylaxis due to TPN in a neonate with observed ultrasound findings during the acute episode never reported in the literature before.
