Abstract
Background Nutritional assessment is important for optimization of patients undergoing elective total joint arthroplasty (TJA). Preoperative nutritional intervention is a potentially modifiable optimization target, but the outcomes of such intervention are not well-studied. The purpose of this study is to assess the impact of nutritional interventions on elective TJA outcomes. Methods Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were utilized to perform a systematic review of the Ovid Medline, Embase, and Cochrane Library systems. Included studies were comprised of patients greater than 18 years of age undergoing a primary unilateral TJA who received a perioperative dietitian-led intervention. Data analyzed included nutritional intervention protocol, patient demographics, length of stay (LOS), postoperative labs and complications, among others. Results Our initial search identified a total of 1766 articles. Four studies representing 5006 patients met inclusion criteria. The studies utilized a protein-dominant diet, with or without a carbohydrate solution accompanied by dietitian assessment or education. The 4 studies found that the intervention group had significantly decreased LOS, fewer albumin infusions, less wound drainage, lower rates of hypocalcemia and hypokalemia, reduced C-reactive protein (CRP) values, improved time out of bed, and decreased overall costs. Conclusion The findings support the potential benefits of perioperative dietitian-led intervention on key outcomes for patients undergoing primary TJA. Surgeons should consider nutritional intervention in their preoperative optimization protocols. Future studies could help elucidate the optimum nutritional regimens and monitoring for idealized intervention and surgical timing. Prospero registration number CRD4202338494.

Abstract
AIMS Many studies show the association between malnutrition and poor prognosis in heart failure (HF) patients. Our research aimed to analyse sex differences in patients with HF with reduced ejection fraction (HFrEF), emphasizing nutritional status and the influence of selected parameters on the prognosis. METHODS AND RESULTS We enrolled 276 consecutive patients diagnosed with HFrEF. Nutritional status was assessed using Mini Nutritional Assessment (MNA), geriatric nutritional risk index (GNRI), and body mass index (BMI). The mean follow-up period was 564.4 ± 346.3 days. The analysed group included 81.2% of men. The median age was 58, interquartile range (IQR) 49-64 years. Among all patients, almost 60% were classified as NYHA III or IV. Half of the participants were at risk of malnutrition, and 2.9% were malnourished. During follow-up, 72 (26.1%) patients died. The female sex was not associated with a higher occurrence of malnutrition (P = 0.99) or nutritional risk (P = 0.85), according to MNA. Coherently, GNRI scores did not differ significantly between the sexes (P = 0.29). In contrast, BMI was significantly higher in males (29.4 ± 5.3 vs. 25.9 ± 4.7; P < 0.001). Impaired nutritional status assessed with any method (MNA, GNRI, BMI) was not significantly associated with a worse prognosis. In multivariable analysis, NYHA class, lower estimated glomerular filtration rate, higher B-type natriuretic peptide (BNP), higher N-terminal fragment of proBNP, and higher uric acid were independent of sex and age predictors of all-cause mortality. CONCLUSION There were no sex differences in the nutritional status in the HFrEF patients, apart from lower BMI in females. Impaired nutritional status was not associated with mortality in both men and women.

Comprehensive biochemical analysis and nutritional evaluation of fatty acid and amino acid profiles in eight seahorse species ( Hippocampus spp.). Heliyon 2024; 10:e33220. [PMID: 39021916 PMCID: PMC11252734 DOI: 10.1016/j.heliyon.2024.e33220] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2024] [Revised: 06/17/2024] [Accepted: 06/17/2024] [Indexed: 07/20/2024] Open
Abstract
Seahorses are increasingly recognized for their nutritional potential, which underscores the necessity for comprehensive biochemical analyses. This study aims to investigate the fatty acid and amino acid compositions of eight seahorse species, including both genders of Hippocampus trimaculatus, Hippocampus kelloggi, Hippocampus abdominalis, and Hippocampus erectus, to evaluate their nutritional value. We employed Gas Chromatography-Mass Spectrometry (GC-MS) and High-Performance Liquid Chromatography (HPLC) to analyze the fatty acid and amino acid profiles of the seahorse species. GC-MS was used to detect 34 fatty acid methyl esters, while HPLC provided detailed amino acid profiles. GC-MS analysis demonstrated high precision with relative standard deviations (RSDs) generally below 2.53 %, satisfactory repeatability (RSDs from 6.55 % to 8.73 %), and stability (RSDs below 2.82 %). Recovery rates for major fatty acids ranged from 98.73 % to 109.12 %. HPLC analysis showed strong separation of amino acid profiles with theoretical plate numbers exceeding 5000. Precision tests yielded RSDs below 1.23 %, with reproducibility and stability tests showing RSDs below 2.73 % and 2.86 %, respectively. Amino acid recovery rates ranged from 97.58 % to 104.66 %. Nutritional analysis revealed significant variations in fatty acid content among the species. Female H. erectus showed higher levels of hexadecanoic acid and saturated fatty acids, while male H. abdominalis had lower concentrations of n-3 full cis 4,7,10,13,16,19-docosahexaenoic acid (DHA). Total lipid yields varied from 3.2491 % to 12.3175 %, with major fatty acids constituting 17.9717 %-74.6962 % of total lipids. In conclusion, this study provides essential insights into the fatty acid and amino acid composition of seahorses, supporting their potential as valuable dietary supplements. The differences between genders in specific fatty acids suggest a nuanced nutritional profile that could be exploited for targeted dietary applications. Further research is needed to explore the seasonal and environmental variations affecting seahorse biochemical composition.

Abstract
To better use the Lecythis pisonis Cambess. biomass, this study investigates whether Sapucaia seed coats present wound healing properties. We analyzed the antibacterial, antioxidant, and wound healing-promoting potentials, plus cytotoxicity and stimulation of vascular endothelial growth factor-A. The chemical composition was analyzed by positive ion mode electrospray ionization Fourier transform ion cyclotron resonance mass spectrometry. A total of 19 compounds were identified, such as proanthocyanidin A1, procyanidins A1, B2, and C1, epigallocatechin, and kaempferol (p-coumaroyl) glycoside. Potent antioxidant strength/index was verified for 2,2-diphenyl-1-picrylhydrazyl radical (IC50 = 0.99 µg/mL) and ferric reducing antioxidant power (IC50 = 1.09 µg/mL). The extract did not present cytotoxicity and promoted significant cell migration and/or proliferation of fibroblasts (p < 0.05). Vascular endothelial growth factor-A was stimulated dose-dependently at 6 µg/mL (167.13 ± 8.30 pg/mL), 12.5 µg/mL (210.3 ± 14.2 pg/mL), and 25 µg/mL (411.6 ± 29.4 pg/mL). Platelet-derived growth factor (PDGF) (0.002 µg/mL) was stimulated at 215.98 pg/mL. Staphylococcus aureus was susceptible to the extract, with a minimum inhibitory concentration of 31.25 µg/mL. The identified compounds benefit the antioxidant activity, promoting hemostasis for the wound healing process, indicating that this extract has the potential for use in dermatological cosmetics.

Abstract
Fat-soluble vitamins (vitamin A, D, E, and K) assume a pivotal role in maintaining human homeostasis by virtue of their enzymatic functions. The daily inclusion of these vitamins is imperative to the upkeep of various physiological processes including vision, bone health, immunity, and protection against oxidative stress. Current research highlights fat-soluble vitamins as potential therapeutics for human diseases, especially cancer. Fat-soluble vitamins exert their therapeutic effects through multiple pathways, including regulation of matrix metalloproteinases' (MMPs) expression and enzymatic activity. As MMPs have been reported to be involved in the pathology of various diseases, such as cancers, cardiovascular diseases, and neurological disorders, regulating the expression and/or activity of MMPs could be considered as a potent therapeutic strategy. Here, we summarize the properties of fat-soluble vitamins and their potential as promising candidates capable of effectively modulating MMPs through multiple pathways to treat human diseases.

Abstract
OBJECTIVES The Global Leadership Initiative on Malnutrition (GLIM) is a framework aiming to standardize malnutrition diagnosis. However, it still needs to be validated, in particular for patients with chronic liver disease. This study aimed to validate the GLIM criteria in patients with liver cirrhosis awaiting liver transplant (LTx). METHODS This was a retrospective observational study carried out with adult patients on the waiting list for LTx, consecutively evaluated between 2006 and 2021. The phenotypic criteria were unintentional weight loss, low body mass index, and reduced muscle mass (midarm muscle circumference [MAMC]). The etiologic criteria were high Model for End-Stage Liver Disease (MELD) and MELD adjusted for serum sodium (MELD-Na) scores, the Child-Pugh score, low serum albumin, and low food intake and/or assimilation. Forty-three GLIM combinations were tested. Sensitivity (SE), specificity (SP), positive and negative predictive values, and machine learning (ML) techniques were used. Survival analysis with Cox regression was carried out. RESULTS A total of 419 patients with advanced liver cirrhosis were included (median age, 52.0 y [46-59 y]; 69.2% male; 68.8% malnourished according to the Subjective Global Assessment [SGA]). The prevalence of malnutrition by the GLIM criteria ranged from 3.1% to 58.2%, and five combinations had SE or SP >80%. The MAMC as a phenotypic criterion with MELD and MELD-Na as etiologic criteria were predictors of mortality. The MAMC and the presence of any phenotypic criteria associated with liver disease parameters and low food intake or assimilation were associated with malnutrition prediction in ML analysis. CONCLUSIONS The MAMC and liver disease parameters were associated with malnutrition diagnosis by SGA and were also predictors of 1-y mortality in patients with liver cirrhosis awaiting LTx.

Abstract
A stroke is a serious life-threatening condition and a leading cause of death and disability that happens when the blood vessels to part of the brain are blocked or burst. While major advances in the understanding of the ischemic cascade in stroke was made over several decades, limited therapeutic options and high mortality and disability have caused researchers to extend the focus toward peripheral changes beyond brain. The largest proportion of microbes in human body reside in the gut and the interaction between host and microbiota in health and disease is well known. Our study aimed to explore the gut microbiota in patients with stroke with comparison to control group. Fecal samples were obtained from 51 subjects: 25 stroke patients (18 hemorrhagic, 7 ischemic) and 26 healthy control subjects. The variable region V3-V4 of the 16S rRNA gene was sequenced using the Illumina MiSeq platform. PICRUSt2 was used for prediction of metagenomics functions. Our results show taxonomic dysbiosis in stroke patients in parallel with functional dysbiosis. Here, we show that stroke patients have (1) increased Parabacteroides and Escherichia_Shigella, but decreased Prevotella and Fecalibacterium; (2) higher transposase and peptide/nickel transport system substrate-binding protein, but lower RNA polymerase sigma-70 factor and methyl-accepting chemotaxis protein, which are suggestive of malnutrition. Nutrients are essential regulators of both host and microbial physiology and function as key coordinators of host-microbe interactions. Manipulation of nutrition is expected to alleviate gut dysbiosis and prognosis and improve disability and mortality in the management of stroke.

Abstract
Thromboembolic complications including cerebrovascular accidents, pulmonary embolism, myocardial infarction, deep vein thrombosis and disseminating intravascular coagulopathy are serious encounters in sever coronavirus disease 2019 (COVID-19) infected patients. This worsens the prognosis and may lead to death or life long morbidities. The laboratory finding of the disturbed haemostasias and the hyperinflammatory response are almost invariably present in COVID-19 patients. Multiple treatment modalities are utilized by the healthcare professionals to overcome the cytokine storm, oxidative stress, endothelial dysfunction, and coagulopathy in these patients. The combined actions of vitamin D (VitD) as a steroid hormone with anti-inflammatory, immunomodulatory, and antithrombotic properties increase the potential of the possible involvement of hypovitaminosis D in the thromboembolic complications of COVID-19 infection, and stimulated researchers and physicians to administer VitD therapy to prevent the infection and/or overcome the disease complications. The current review highlighted the immunomodulatory, anti-inflammatory, antioxidative and hemostatic functions of VitD and its interrelation with the renin-angiotensin-aldosterone system (RAAS) pathway and the complement system. Additionally, the association of VitD deficiency with the incidence and progression of COVID-19 infection and the associated cytokine storm, oxidative stress, hypercoagulability, and endothelial dysfunction were emphasized. Normalizing VitD levels by daily low dose therapy in patients with hypovitaminosis D below (25 nmol/l) is essential for a balanced immune response and maintaining the health of the pulmonary epithelium. It protects against upper respiratory tract infections and decreases the complications of COVID-19 infections. Understanding the role of VitD and its associated molecules in the protection against the coagulopathy, vasculopathy, inflammation, oxidative stress and endothelial dysfunction in COVID-19 infection could lead to new therapeutic strategies to prevent, treat, and limit the complications of this deadly virus infection.

Abstract
Chronic wounds are the outcome of an imbalanced inflammatory response caused by sustenance of immune microenvironment. In this context, tissue engineered graft played great role in healing wounds but faced difficulty in scar remodelling, immune rejection and poor vascularization. All the limitations faced are somewhere linked with the immune cells involved in healing. In this consideration, immunomodulatory biomaterials bridge a large gap with the delivery of modulating factors for triggering key inflammatory cells responsible towards interplay in the wound micro-environment. Inherent physico-chemical properties of biomaterials substantially determine the nature of cell-materials interaction thereby facilitating differential cytokine gradient involved in activation or suppression of inflammatory signalling pathways, and followed by surface marker expression. This review aims to systematically describe the interplay of immune cells involved in different phases in the wound microenvironment and biomaterials. Additionally, it also focuses on modulating innate immune cell responses in the context of triggering the halted phase of the wound healing, i.e., inflammatory phase. The various strategies are highlighted for modulation of wound microenvironment towards wound regeneration including stem cells, cytokines, growth factors, vitamins, and anti-inflammatory agents to induce interactive ability of biomaterials with immune cells. The last section focuses on prospective approaches and current potential strategies for wound regeneration. This includes the development of different models to bridge the gap between mouse models and human patients. Emerging new tools to study inflammatory response owing to biomaterials and novel strategies for modulation of monocyte and macrophage behaviour in the wound environment are also discussed.

Effects of Oral Nutritional Supplementation on Patients with Venous Ulcers: A Clinical Trial. J Clin Med 2022; 11:jcm11195683. [PMID: 36233551 PMCID: PMC9570985 DOI: 10.3390/jcm11195683] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2022] [Revised: 09/14/2022] [Accepted: 09/20/2022] [Indexed: 11/30/2022] Open
Abstract
Background: The dosage and safety of nutritional supplements for patients with venous ulcers are still not well established. Aim: To evaluate the effects of a high calorie, high protein, arginine-, zinc-, and vitamins A, C, and E-enriched nutritional supplement on the biochemical profile, dietary intake, anthropometry, muscle strength, and characteristics of lesions of patients with venous ulcers. Methods: A controlled before−after clinical trial with a four-week follow-up involved 27 patients with venous ulcers under outpatient treatment in Brazil. It was administered in two to three doses per day (200 mL each) of a high-calorie and high-protein supplement enriched with arginine, zinc, and vitamins A, C, and E. Patients were assessed for anthropometric parameters, dietary intake, biochemical tests, and healing conditions according to the Pressure Ulcer Scale for Healing (PUSH). Results: It was observed that an increase in energy and protein supply led to an adequate intake of immunonutrients (zinc and vitamins A, C, and E), increased body weight, increased body mass index, and stronger handgrip strength. The injury area and the score on the PUSH notably decreased after the intervention (p < 0.001). Conclusions: The administered supplement, at the tested dosage, improved the nutritional status and characteristics of lesions in patients with venous ulcers.

Abstract
BACKGROUND Whether to conduct enteral ecoimmunonutrition (EEIN) in patients undergoing hepatectomy remains controversial. This study aimed to systematically explore the efficacy and safety of EEIN in patients undergoing hepatectomy. SUBJECT We performed searches in the Embase, PubMed, Medline, Cochrane Library, Chinese Scientific Journal Database (VIP), Chinese National Knowledge Infrastructure (CNKI) and Wanfang databases. RESULTS A total of 9 randomized controlled trials (705 patients) were included. The meta-analysis revealed a significantly shorter time to first postoperative flatus (h) (MD, -14.60; 95% CI, -16.06~-13.15; P < 0.00001); lower levels of alanine aminotransferase (µmol/L) (MD, -22.26; 95% CI, -28.42~-16.10; P < 0.00001), aspartate transaminase (µmol/L) (MD, -53.79; 95% CI, -57.37~-50.21; P < 0.00001), total bilirubin (µmol/L) (MD, -16.28; 95% CI, -17.77~-14.79; P < 0.00001), direct bilirubin (µmol/L) (MD, -8.77; 95% CI, -9.65~-7.88; P < 0.00001), endotoxin (ng/L) (MD, -0.78; 95% CI, -0.88~-0.68; P < 0.00001), tumor necrosis factor-α (pg/ml) (MD, -79.69; 95% CI, -99.90~-59.49; P < 0.00001), and interleukin-6 (pg/ml) (MD, -46.29; 95% CI, -50.24~-42.34; P < 0.00001); and higher levels of immunoglobulin A (g/L) (MD, 0.24; 95% CI, 0.14~0.35; P < 0.00001), immunoglobulin G (g/L) (MD, 1.52; 95% CI, 1.22~1.82; P < 0.00001), and immunoglobulin M (g/L) (MD, 0.12; 95% CI, 0.05~0.20; P = 0.0007) in the EEIN group than in the enteral or parenteral nutrition (EN/PN) groups. CONCLUSION Enteral ecoimmunonutrition support in patients undergoing hepatectomy may effectively protect liver function, reduce serum endotoxin levels and inflammatory factors, improve the immune function of patients, and promote the recovery of postoperative gastrointestinal function, which is worthy of clinical application.

Abstract
This study was carried out to evaluate the effect of Glutamine, as a dipeptide or a free amino acid form, on the progression of burn injuries in rats. Thirty male Wistar rats were burned with a comb metal plate heated in boiling water (98 °C) for three minutes, creating four rectangular full-thickness burn areas separated by three unburned interspaces (zone of stasis) in both dorsum sides. The animals were randomized into three groups (n=10): saline solution (G1-Control) and treated groups that orally received Glutamine as dipeptide (G2-Dip) or free amino acid (G3-FreeAA). Two and seven days after burn injury, lesions were photographed for unburned interspaces necrosis evolution assessment. Seven days after injury, glutathione seric was measured and histopathological analysis was performed. By photographs, there was a significant reduction in necrosis progression in G3-Free-AA between days two and seven. Histopathological analysis at day 7 showed a significantly higher stasis zone without necrosis and a higher number of fibroblasts in G2-Dip and G3-FreeAA compared with G1-Control. Also, glutathione serum dosage was higher in G2-Dip. The plasmatic glutathione levels were higher in the G2-Dip than the G1-Control, and there was a trend to higher levels in G3-FreeAA. The reduction in histological lesions, greater production of fibroblasts, and greater amounts of glutathione may have benefited the evolution of burn necrosis, which showed greater preservation of interspaces.

Abstract
Oral mucositis (OM) is a painful condition caused by chemotherapeutic or radiotherapeutic cancer treatments, occurring in patients with different tumour characteristics and locations. OM greatly impacts a patient’s quality of life and cancer recovery. Current OM management strategies are not providing sufficient prevention and treatment; new approaches to injury management are needed. Studies on the benefit of omega-3 free fatty acids (FFA) in human health have increased significantly in recent years. FFA properties have been studied extensively, including their potential therapeutic use in inflammatory conditions. However, omega-3 FFA’s use as a supplementary treatment for OM has not been clinically tested. Preliminary evidence suggests that utilising FFA to manage OM could be a useful strategy for lesion management, assisting with healthy oral mucosa recovery. This review will describe the incidence, risk factors, biology of OM and the current treatment strategies, leading to a discussion of the utility of omega-3 FFA as a novel therapeutic agent for OM.

Abstract
Long-chain Omega-3 polyunsaturated fatty acids (Omega-3 PUFAs) are widely recognized as powerful negative regulators of acute inflammation. However, the precise role exerted by these dietary compounds during the healing process is still largely unknown, and there is increasing interest in understanding their specific effects on the implicated cells/molecular factors. Particular attention is being focused also on their potential clinical application in chronic pathologies characterized by delayed and impaired healing, such as diabetes and vascular diseases in lower limbs. On these bases, we firstly summarized the current knowledge on wound healing (WH) in skin, both in normal conditions and in the setting of these two pathologies, with particular attention to the cellular and molecular mechanisms involved. Then, we critically reviewed the outcomes of recent research papers investigating the activity exerted by Omega-3 PUFAs and their bioactive metabolites in the regulation of WH in patients with diabetes or venous insufficiency and showing chronic recalcitrant ulcers. We especially focused on recent studies investigating the mechanisms through which these compounds may act. Considerations on the optimal dietary doses are also reported, and, finally, possible future perspectives in this area are suggested.

Abstract
Wound healing requires cooperation between different cell types, among which macrophages play a central role. In particular, inflammatory macrophages are engaged in the initial response to wounding, and alternatively activated macrophages are essential for wound closure and the resolution of tissue repair. The links between temporal activation-induced changes in the metabolism of such macrophages and the influence this has on their functional states, along with the realization that metabolites play both intrinsic and extrinsic roles in the cells that produce them, has focused attention on the metabolism of wound healing. Here, we discuss macrophage metabolism during distinct stages of normal healing and its related pathologic processes, such as during cancer and fibrosis. Further, we frame these insights in a broader context of the current understanding of macrophage metabolic reprogramming linked to cellular activation and function. Finally, we discuss parallels between the metabolism of macrophages and fibroblasts, the latter being a key stromal cell type in wound healing, and consider the importance of the metabolic interplay between different cell types in the wound microenvironment.

Abstract
BACKGROUND Arthroplasties in elderly patients are surgeries performed to ensure their quality of life. Perioperative care with specific nutrients can improve nutrition status and metabolic response to orthopedic surgeries, such as total knee arthroplasty (TKA) and total hip arthroplasty (THA). METHODS Retrospective study with elderly patients divided into 2 groups: control and immunonutrition. The immunonutrition group was instructed to start oral intake of the nutrition supplement 5 days before and to resume it 5 days after arthroplasty (200 mL, 3 times per day). The following were analyzed as primary and secondary outcomes: length of stay (LOS), infectious and noninfectious complications, need for intensive care unit (ICU), transfusion requirement, and C-reactive protein. RESULTS A total of 3015 elderly patients met the inclusion criteria: control group (n = 1398) and immunonutrition group (n = 1617). Overall, 81.2% were women and mean age was 72.6 ± 6.9 years. Immunonutrition group had a shorter LOS in hours (32.0 ± 19.4 vs 56.0 ± 26.4; P < .001) and lower rates of infectious complications (2.2% vs 4.6%; P < .001). Noninfectious complications and need for ICU also had lower rates in the immunonutrition group. In the logistic regression analysis, immunonutrition reduced the chance of infectious complications by 55% (odds ratio [OR], 0.45; 95% CI, 0.30-0.68; P < .001) even after adjusting for variables (OR, 0.45; 95% CI, 0.28-0.71; P < .001). CONCLUSION Perioperative immunonutrition in elderly patients undergoing THA or TKA may shorten postoperative LOS and reduce infectious and noninfectious complications and transfusion requirement.

Abstract
Aim of this retrospective study was to estimate the effect of oral supplementation with amino acids (AA) on corneal nerves regrowth after excimer laser refractive surgery with photorefractive keratectomy (PRK). Based on the pre and post-surgical treatment received, 40 patients with 12 months of follow-up were distributed in two groups: 20 patients had received oral AA supplementation 7 days before and 30 days after PRK, and 20 patients without AA supplementation, as untreated reference control. All patients followed the same standard post-operative topical therapy consisting of an association of antibiotic and steroid plus sodium hyaluronate during the first week, then steroid alone progressively decreasing during 30 days and sodium hyaluronate for the following 3 months. In vivo corneal confocal microscopy was used to evaluate the presence of sub-basal corneal nerve fibers during 12 months after PRK. Results have shown that sub-basal nerves regenerated significantly faster (p <0.05), and nerve fibers density was significantly higher (p <0.05) with a more regular pattern in the eyes of AA treated patients with respect to the untreated control group. Therefore, our data indicate that oral supplementation with AA improved significantly corneal nerve restoration after PRK and could thus be considered as an additional treatment during corneal surgical procedures.

Abstract
Purpose Gastric cancer is a common tumor type associated with nutritional and immune status. The aim of the current study was to investigate the prognostic value of a preoperative prognostic nutritional index (PNI), composed of nutritional factors and immune factors in elderly patients undergoing gastric cancer surgery. Patients and Methods A total of 454 patients undergoing gastric cancer surgery were divided into two groups based on preoperative PNI scores: ≤45.1 (n = 307) and >45.1 (n = 147). Survival analysis was performed using the Kaplan-Meier method and Log rank tests. Univariate and multivariate analyses were conducted to identify independent prognostic factors using a Cox proportional hazards model. Results According to the X-tile program, the optimal cutoff value for predicting overall survival (OS) with the PNI was 45.1. The receiver operating characteristic analysis revealed that PNI exhibited 70.6% sensitivity and 56.5% specificity for predicting death during long-term follow-up. The cumulative incidence of postoperative 4-year mortality indicated that the risk of death increased significantly for PNI ≤45.1. In multivariate analysis, preoperative PNI was a significant independent predictor of mortality. In the age-stratified subgroup analysis, preoperative PNI was more sensitive for the old elderly subgroup than for the young elderly subgroup. Conclusion Preoperative PNI is a sensitive and specific prognostic predictor among elderly patients undergoing gastric cancer surgery.

Abstract
Burn injury is still a global health problem due to its high incidence. Healing of burn wounds requires an optimal state of the body that is characterized by serum albumin level, especially in the category of patients that require skin graft to cover the wound caused by the deep burn. This study investigates the relationship between albumin levels and the outcome of split-thickness skin graft (STSG) and obtains a tolerance limit for albumin levels that can be successful in STSG. This was a prospective cohort study at our Plastic Surgery Center in Bandung, West Java, Indonesia from June 2019 to November 2020. Fortyseven burn injury patients who had undergone STSG qualified as the study subjects based on the criteria set. Of these patients, 85.11% were male and 68.08% were in the productive age. Preoperative albumin level has no significant correlation with graft outcome (P>0.05). Area Under the Curve (AUC) is 0.758; (95% CI: 0.605, 0.910). The optimal cut-off point for albumin levels is 2.175 (sensitivity of 0.78 and a specificity of 0.714). In our study, graft healing has no significant correlation with albumin levels. Further study is needed to assess the relationship between serum albumin levels (preoperative and postoperative) with outcome of the graft, and assess infection status.

Abstract
Chagas disease, caused by Trypanosoma cruzi, is a major neglected tropical disease that occurs mainly as chronic infection and systemic infection. Currently, there is no suitable and effective drug to treat this parasitic disease. Administration of nutrients with immunomodulatory properties, such as arginine and nitric oxide radicals, may be helpful as antiparasitic therapy. In this study, we evaluated the effects of arginine supplementation during the acute phase of infection under the development of chronic Chagas' heart disease in Swiss mice inoculated with the Berenice-78 strain of T. cruzi. The effectiveness of arginine was determined by daily detection of the parasite in the blood and long-term serum levels of nitric oxide and tumor necrosis factor-alpha, in addition to evaluation of heart tissue damage. Arginine could flatten parasitemia and prevent elevation of tumor necrosis factor-alpha in T. cruzi-infected mice. Regarding chronic inflammatory myocardial derangements, similar findings were verified among T. cruzi-infected groups. Arginine promoted collagenogenesis in the heart muscle tissue of T. cruzi-infected arginine-supplemented group. These data show the paradoxical benefits of arginine in improving the outcome of Chagas chronic cardiomyopathy.

Abstract
Many researches have been undergone to hasten the natural wound healing process. In this study, several Hibiscus species (leaves) were extracted with petroleum ether, methanol, and their mucilage was separated. All the tested species extracts were assessed for their viability percentage using the water-soluble tetrazolium. H.syriacus was the plant of choice to be incorporated in a new drug delivery system and evaluated for its wound healing activity. H.syriacus petroleum ether extract (PEE) showed a high percentage of palmitic and oleic acids while its mucilage demonstrated high glucosamine and galacturonic acid. It was selected to be formulated and pharmaceutically evaluated into three different composite sponges using chitosan in various ratios. Fourier-transformed infrared spectroscopy investigated the chemical interaction between the utilized sponges' ingredients. Morphological characteristics were evaluated using scanning electron microscopy. H.syriacus composite sponge of mucilage: chitosan (1:5) was loaded with three different concentrations of PEE. Medicated formulations were assessed in rat model of excision wound model. The wound healing ability was clearly proved by the clinical acceleration, histopathological examination, and modulation of correlated inflammatory parameters as tumor necrosis factor in addition to vascular endothelial growth factor suggesting a promising valuable candidate that supports the management of excision wounds using single-dose preparation.

Abstract
Currently, the world is under a pandemic of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), responsible for coronavirus disease 2019 (COVID-19). This disease is characterized by a respiratory syndrome that can progress to an acute respiratory distress syndrome. To date, limited effective therapies are available for the prevention or treatment of COVID-19; therefore, it is necessary to propose novel treatment options with immunomodulatory effects. Vitamin D serves functions in bone health and has been recently reported to exert protective effects against respiratory infections. Observational studies have demonstrated an association between vitamin D deficiency and a poor prognosis of COVID-19; this is alarming as vitamin D deficiency is a global health problem. In Latin America, the prevalence of vitamin D deficiency is unknown, and currently, this region is in the top 10 according to the number of confirmed COVID-19 cases. Supplementation with vitamin D may be a useful adjunctive treatment for the prevention of COVID-19 complications. The present review provides an overview of the current knowledge of the potential immunomodulatory effects of vitamin D in the prevention of COVID-19 and sets out vitamin D recommendations for the Latin American population.

Abstract
ABSTRACT Although hospital malnutrition is highly prevalent worldwide, it is difficult to compare the data due to the different nutritional assessment tools used. The Global Leadership Initiative on Malnutrition, which aims to operationalize malnutrition diagnosis, consists of five criteria: three phenotypic and two etiological criteria. Many researchers have studied the applicability and clinical relevance of Global Leadership Initiative on Malnutrition, and methodological standards have been established by the Global Leadership Initiative on Malnutrition commission for the application and possible validation of the tool. This study aimed to analyze the methodological processes of the studies that compared the Global Leadership Initiative on Malnutrition with a test tool. A literature review was conducted by the Portal Periódicos from Coordenação de Aperfeiçoamento de Pessoal de Nível Superior between November 2020 and January 2021. This review included articles published in English between 2016 and 2021 that compared the Global Leadership Initiative on Malnutrition with another tool used for diagnosing malnutrition. The sample had 13 articles, of which 11 did not adequately describe how the Global Leadership Initiative on Malnutrition criteria were applied. Only two studies utilized a combination of the phenotypic and etiological criteria. Some studies differed from the methodological recommendations of the Global Leadership Initiative on Malnutrition commission. Thus, it seems that applying the Global Leadership Initiative on Malnutrition in a manner different from the original framework elicited limited results regarding the applicability and reliability of the tool. Therefore, more studies should be conducted on the application of the GLIM Global Leadership Initiative on Malnutrition in different populations and contexts as per the patterns suggested to determine its actual applicability and reliability.

Abstract
INTRODUCTION Traumatic brain injury (TBI) is the leading cause of paediatric trauma death and disability worldwide. The 'Guidelines for the Management of Severe Traumatic Brain Injury (Fourth Edition)' recommend that nutritional goals should be achieved within 5-7 days of injury. Immune-enhancing nutrition or immunonutrition, referring to the addition of specialised nutrients, including glutamine, alanine, omega-3 fatty acids and nucleotides, to standard nutrition formulas, may improve surgical outcomes in the perioperative period. However, the role of immune-enhancing nutritional supplements for patients with paediatric TBI remains unclear. We will conduct a systematic review to determine the efficacy and safety of immunonutrition for patients with paediatric TBI and provide evidence for clinical decision-making. METHODS AND ANALYSIS Studies reporting immune-enhancing nutrition treatments for patients with paediatric TBI will be included. Outcomes of interest include the length of hospital stay, wound infections, all-cause mortality, non-wound infection, including pneumonia, urinary tract infection and bacteraemia, and the reports adverse events. Duration of follow-up has no restriction. Primary studies consisting of randomised controlled trials (RCTs) and non-RCTs will be eligible for this review, and only studies published in English will be included. We will search the Medline, Embase and Cochrane Library databases from their inception dates to January 2020. We will also search clinicaltrials.gov and the WHO International Clinical Trials Registry Platform for additional information. Two reviewers will independently select studies and extract data. Risk-of-bias will be assessed with tools based on the Cochrane risk-of-bias criteria and Newcastle-Ottawa Quality Assessment Scale. A meta-analysis will be used to pool data when there are sufficient studies with homogeneity. Heterogeneity of the estimates across studies will be assessed; if necessary, a subgroup analysis will be performed to explore the source of heterogeneity. The Grades of Recommendation, Assessment, Development and Evaluation method will be applied to assess the level of evidence obtained from this systematic review. ETHICS AND DISSEMINATION The proposed systematic review and meta-analysis will be based on published data, and thus ethical approval is not required. The results of this review will be published. PROSPERO REGISTRATION NUMBER CRD42020154814.

Abstract
BACKGROUND Propolis is a resinous substance produced by bees. Propolis extracts have been used for anti-inflammatory and antimicrobial activities. The use of propolis dietary supplements has been increasing in the United States and the rest of the world. OBJECTIVE A simple, economic, and valid analytical method is needed for quality assessment of dietary supplements and extracts claiming to contain propolis. METHODS A ultra-high performance liquid chromatography (UHPLC) quadropole time-of-flight-MS method was used to characterize the chemical composition of northern Indian propolis. Fourteen major phenolic compounds were quantified using a UHPLC-DAD method. An HPTLC method was used to develop chemical fingerprinting profiles for propolis extracts and dietary supplements. The seven propolis extracts and 14 dietary supplements purchased in the U.S. were analyzed using the UHPLC-DAD-QToF method. RESULTS Fifty-seven compounds belonging to phenolic, coumarin, fatty acid, and terpene classes were identified in propolis extracts. Based on quantification results, the content of 14 phenolic compounds in propolis extracts varied from 19-32% in dietary supplements, a significant variation to the recommended daily intake (0.2-94 mg/day). CONCLUSIONS/HIGHLIGHTS The developed analytical methods can be used for quality assessment of propolis extracts and dietary supplements.

Abstract
Wound healing is affected by several factors. Preexisting diagnoses may significantly alter, delay, or inhibit normal wound healing. This is most commonly seen with chronic disorders, such as diabetes and renal failure, but also occurs secondary to aging and substance abuse. Less commonly, genetic or inflammatory disorders are the cause of delayed wound healing. In some cases, it is not the illness, but the treatment that can inhibit wound healing. This is seen in patients getting chemotherapy, radiation, steroids, methotrexate, and a host of other medications. Understanding these processes may help treat or avoid wound healing problems.

Preoperative nutrition-enhanced recovery after surgery protocol for thoracic neoplasms. J Thorac Cardiovasc Surg 2020; 162:710-720.e1.

Abstract
OBJECTIVES Because patients' preoperative nutritional status influences the outcomes, we have used a preoperative nutrition program for surgical patients for a 2-year period and compared the results with those from a cohort treated in the previous 2 years. METHODS We retrospectively reviewed curative thoracic neoplasm resections from July 15, 2016, to July 15, 2018, in patients who had received a preoperative nutritional-enhanced recovery after surgery (N-ERAS) protocol. The protocol consisted of 5 days of an oral immunonutrition drink 3 times daily, daily receipt of probiotics, and a carbohydrate-loading drink the night before surgery. The historical control cohort (standard group) included those patients who had undergone surgery by the same surgeon during the previous 24 months. We excluded patients who had undergone esophageal, diagnostic, benign, emergency, or palliative procedures. Nonparametric and parametric statistical tests were used to analyze the data. RESULTS The data from 462 patients were analyzed: 229 N-ERAS patients and 233 standard patients. No significant demographic or caseload differences were found between the 2 groups. The major significant outcome differences included fewer postoperative complications (30 [13.1%] in the N-ERAS group vs 60 [25.8%] in the standard group; P < .001) and shorter hospital stays (3.8 ± 1.9 days for the N-ERAS group vs 4.4 ± 2.6 days for the standard group; P = .001). Use of the N-ERAS protocol resulted in a 16% reduction ($2198; P < .001) in the mean direct hospital costs/patient. Consequently, for the N-ERAS cohort, the hospital was likely saved $503,342 during the 2-year period for the 229 patients just by using the N-ERAS protocol. CONCLUSIONS Thoracic surgeons should consider using the nontoxic, patient-compliant N-ERAS protocol for their patients, with an expectation of improved clinical results at lower hospital costs-an important consideration when exploring methods to decrease costs because hospitals are increasingly being paid by a negotiated prospective bundled payment reimbursement model.

Abstract
BACKGROUND The prognostic nutritional index (PNI) has recently been reported to associate with the surgical prognosis of patients with some cardiovascular diseases. However, the prognosis significance of the preoperative PNI in patients with acute type A aortic dissection (AAAD) remains unclear. OBJECTIVES The present study aimed to explore the relationship between PNI and postoperative in-hospital mortality in patients with AAAD. METHODS Between June 2013 and December 2019, we retrospectively reviewed the clinical data of 651 patients undergoing AAAD surgery. Patients were divided into two groups according to the median PNI. The risk factors of postoperative in-hospital mortality were identified by univariate and multivariate logistic regression analysis. RESULTS In-hospital mortality was significantly more common in the low group (24.8% vs 16.3%: P = .007). The percentage of prolonged mechanical ventilation (58.9% vs 49.8%: P = .020) and the median duration of intensive care unit stays (7.0 vs 6.0 days: P = .003) were also higher and longer in the low group. Multivariate logistic regression analysis showed that the PNI, age, hypertension, and operation time independently predicted in-hospital mortality. Besides, compared with patients with a history of hypertension, the low PNI affected in-hospital mortality more than those without (odds ratio [OR]: 2.07; 95% confidence interval [CI]: 1.20-3.56; P = .009). CONCLUSIONS Lower PNI may be independently associated with in-hospital mortality of patients after AAAD surgery.

Despite advances in therapeutic strategies for the management of patients with severe burns, the sequelae are pathophysiologically profound, up to the systemic and metabolic levels. Management of patients with a severe burn injury is a long-term, complex process, with treatment dependent on the degree and location of the burn and total body surface area (TBSA) affected. In adverse conditions with limited resources, efficient triage, stabilisation, and rapid transfer to a specialised intensive care burn centre is necessary to provide optimal outcomes. This initial lag time and the form of primary treatment initiated, from injury to specialist care, is crucial for the burn patient. This study aims to investigate the efficacy of a novel visco-elastic burn dressing with a proprietary bio-stimulatory marine mineral complex (MXC) as a primary care treatment to initiate a healthy healing process prior to specialist care. METHODS A new versatile emergency burn dressing saturated in a >90% translucent water-based, sterile, oil-free gel and carrying a unique bio-stimulatory marine mineral complex (MXC) was developed. This dressing was tested using LabSkin as a burn model platform. LabSkin a novel cellular 3D-dermal organotypic full thickness human skin equivalent, incorporating fully-differentiated dermal and epidermal components that functionally models skin. Cell and molecular analysis was carried out by in vitro Real-Time Cellular Analysis (RTCA), thermal analysis, and focused transcriptomic array profiling for quantitative gene expression analysis, interrogating both wound healing and fibrosis/scarring molecular pathways. In vivo analysis was also performed to assess the bio-mechanical and physiological effects of this novel dressing on human skin. RESULTS This hybrid emergency burn dressing (EBD) with MXC was hypoallergenic, and improved the barrier function of skin resulting in increased hydration up to 24 h. It was demonstrated to effectively initiate cooling upon application, limiting the continuous burn effect and preventing local tissue from damage and necrosis. xCELLigence RTCA® on primary human dermal cells (keratinocyte, fibroblast and micro-vascular endothelial) demonstrated improved cellular function with respect to tensegrity, migration, proliferation and cell-cell contact (barrier formation) [1]. Quantitative gene profiling supported the physiological and cellular function finding. A beneficial quid pro quo regulation of genes involved in wound healing and fibrosis formation was observed at 24 and 48 h time points. CONCLUSION Utilisation of this EBD + MXC as a primary treatment is an effective and easily applicable treatment in cases of burn injury, proving both a cooling and hydrating environment for the wound. It regulates inflammation and promotes healing in preparation for specialised secondary burn wound management. Moreover, it promotes a healthy remodelling phenotype that may potentially mitigate scarring. Based on our findings, this EBD + MXC is ideal for use in all pre-hospital, pre-surgical and resource limited settings.

Abstract
BACKGROUND & AIMS The Global Leadership Initiative on Malnutrition (GLIM) published a new international standard for defining malnutrition in 2018. The GLIM criteria were compared with the European Society for Clinical Nutrition and Metabolism (ESPEN) criteria in relation to physical function and mortality risk in patients with cardiovascular disease (CVD). METHODS A total of 921 CVD patients ≥ 20 years old (67.8 ± 13.4 years, 631 men) hospitalised for heart failure, acute coronary syndrome and other conditions were stratified according to the presence or absence of malnutrition according to the GLIM and ESPEN criteria. Physical function was assessed by measuring grip strength, 6-minute walking distance and quadriceps isometric strength before hospital discharge, and the endpoint was all-cause mortality. RESULTS During the median follow-up period of 2.3 years (interquartile range, 0.9-3.5 years), 194 deaths occurred in the study population. Malnutrition defined by the GLIM criteria was significantly associated with low physical function. Malnutrition defined by both the GLIM and ESPEN criteria was significantly related to all-cause mortality (P < 0.05). CONCLUSIONS Malnutrition defined according to the GLIM criteria was a predictor of both low physical function and mortality in patients with CVD.

New Evidence and Insights on Dalbavancin and Wound Healing in a Mouse Model of Skin Infection. Antimicrob Agents Chemother 2020; 64:AAC.02062-19. [PMID: 31932371 DOI: 10.1128/aac.02062-19] [Citation(s) in RCA: 23] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2019] [Accepted: 01/08/2020] [Indexed: 12/11/2022] Open
Abstract
Dalbavancin is an effective antibiotic that is widely used to treat skin infection. Our aim was to determine the effect of dalbavancin administration on wound healing compared to that of vancomycin and to elucidate if epidermal growth factor receptor (EGFR), matrix metalloproteinase 1 (MMP-1), MMP-9, and vascular endothelial growth factor (VEGF) could be involved in its therapeutic mechanism. A mouse model of methicillin-resistant Staphylococcus aureus (MRSA) skin infection was established. Mice were treated daily with vancomycin (10 mg/kg) and weekly with dalbavancin at day 1 (20 mg/kg) and day 8 (10 mg/kg). After 14 days, wounds were excised, and bacterial counts were performed. Wound healing was assessed by histological and immunohistochemical staining, followed by protein extraction and immunoblotting. Our microbiological results confirmed that both dalbavancin and vancomycin are effective in reducing the bacterial load in wounds. The dalbavancin group showed a strong effect compared with infected untreated animals and the vancomycin-treated group. The wounds treated with dalbavancin showed robust epidermal coverage with reconstitution of the regular and keratinized epidermal lining and well-organized granulation tissue with numerous blood vessels, although slightly less than that in the uninfected group. While in the vancomycin-treated group the epithelium appeared, in general, still hypertrophic, the granulation tissue appeared even less organized. We observed elevated EGFR and VEGF expression in both treated groups, although it was higher in dalbavancin-treated mice. MMP-1 and MMP-9 were decreased in uninfected tissue and in both treated tissues compared with untreated infected wounds. This study showed faster healing with dalbavancin treatment that might be associated with higher EGFR and VEGF levels.

Abstract
BACKGROUND Surgical site infections (SSIs) are among the most common healthcare-associated infections. Under-nutrition is an important risk factor for SSIs and can lead to delayed wound healing and longer hospital stays. Oral nutritional supplements are prescribed to reduce the risk of infection and improve health status, but data from randomised controlled trials (RCTs) have shown mixed results. Thus, the objective of our planned systematic review is to evaluate oral nutritional supplements on preventing SSIs in adult surgical patients METHODS: RCTs conducted in adult surgical patients who receive oral nutritional support will be included. The primary outcome will be the incidence of SSIs (within 30 days of surgery or within 90 days for joint replacement surgery). Secondary outcomes will be changes in nutritional status, mortality, health-related quality of life and costs. Literature searches will be conducted in several electronic databases (from inception onwards): MEDLINE, Embase, CINAHL and The Cochrane Central Register of Controlled Trials (CENTRAL). Grey literature will be identified through searching clinical trial registers and dissertation databases. Two reviewers will independently screen all citations, full-text articles and abstract data. The study methodological quality (or bias) will be appraised using the Cochrane risk of bias tool. If feasible, we will conduct random effects meta-analysis where appropriate. DISCUSSION This systematic review will evaluate the evidence for pre- and post-surgical intervention with oral nutritional supplements in adults. Findings from this planned review may inform subsequent nutritional interventions for hospitalised patients who undergo surgery. SYSTEMATIC REVIEW REGISTRATION PROSPERO CRD42020140954.

Abstract
BACKGROUND The use of glutamine and arginine has shown several advantages in postoperative outcomes in patients after gastrointestinal surgery. We determined the effects of its use in patients with enterocutaneous fistula after operative treatment. PATIENTS AND METHODS Forty patients with enterocutaneous fistula were randomly assigned to one of two groups. The control group received the standard medical care while the patients of the experimental group were supplemented with enteral administration of 4.5 g of arginine and 10 g of glutamine per day for 7 days prior to the surgery. The primary outcome variable was the recurrence of the fistula and the secondary outcomes were preoperative and postoperative serum concentrations of interleukin 6 and C-reactive protein and postoperative infectious complications. RESULTS Twenty patients were assigned to each group. The fistula recurred in two patients (10%) of the experimental group and in nine patients (45%) of the control group (P < 0.001). We found a total of 13 infectious complications in six patients of the control group (all with fistula recurrence) and none in the experimental group. Mean preoperative serum concentrations of interleukin 6 and C-reactive protein were lower in patients from the experimental group. In addition, these levels were lower in patients who had recurrence if compared to patients that did not recur. CONCLUSION Preoperative administration of oral arginine and glutamine could be valuable in the postoperative recovery of patients with enterocutaneous fistulas submitted to definitive surgery.

Abstract
Background. Acute kidney injury (AKI) is one of the common complications after living donor liver transplantation (LDLT) and is associated with increased mortality and morbidity. The prognostic nutritional index (PNI) has been used as a predictive model for postoperative complications. Here, we create a new predictive model based on the PNI and compared its predictive accuracy to other models in patients who underwent LDLT. Material and Methods: The data from 423 patients were collected retrospectively. The patients were dichotomized into the non-AKI and the AKI groups. Multivariate adjustment for significant postoperative variables based on univariate analysis was performed. A new predictive model was created using the results from logistic regression analysis, dubbed the modified-PNI model (mPNI). The area under the receiver operating characteristic curve (AUC) was generated to determine the diagnostic accuracy and cutoff value of individual models. The net reclassification improvement (NRI) and integrated discrimination improvement (IDI) were calculated to investigate diagnostic improvement by the mPNI. Results: Fifty-four patients (12.7 %) were diagnosed with AKI within 1-week after LDLT. The mPNI had the highest predictive accuracy (AUC = 0.823). The model of end-stage liver disease (MELD) scores and PNI were 0.793 and 0.749, respectively, and the INR and serum bilirubin were 0.705 and 0.637, respectively. The differences in the AUCs were statistically significant among the mPNI, PNI, INR, and serum bilirubin. The cutoff value for mPNI was 8.7. The NRI was 10.4% and the IDI was 3.3%. Conclusions: The mPNI predicted AKI within 1-week better than other scoring systems in patients who underwent LDLT. The recommended cutoff value of mPNI is 8.7.

Abstract
BACKGROUND Amino acids are associated with wound healing in traumatic wounds and burns, although their effects on healing in patients with diabetic foot ulcers (DFUs) are limited. This study aimed to evaluate and identify specific amino acids associated with healing outcomes of patients with DFUs. METHODS Sixty-two out of 85 patients who completed the in-hospital treatment for limb-threatening DFUs were enrolled. All ulcers had epithelialization without clinical evidence of infection at discharge. The patients and their families were instructed on foot-care techniques and committed to regular follow-up for 1 year. Baseline characteristics, PEDIS wound classification, laboratory data and serum amino acid levels were used to analyze their predictive power. RESULTS Fifty-seven patients completed the study in which 38 had healed and 19 had unhealed ulcers. The unhealed group had higher incidence of coronary artery disease and larger wound size. Most patients received endovascular therapy (81.6% healed group; 78.9% unhealed group) before enrollment. Following adjustments for clinical factors, the serum levels of arginine (326.4 μmol/L vs. 245.0 μmol/L, P = 0.045), isoleucine (166.7 μmol/L vs. 130.1 μmol/L, P = 0.019), leucine (325.8 μmol/L vs. 248.9 μmol/L, P = 0.039), and threonine (186.7 μmol/L vs. 152.0 μmol/L, P = 0.019) were significantly higher in the healed group. CONCLUSIONS The amino acids associated with wound healing in DFUs differ from those reported for traditional traumatic wounds. These findings affirm the necessity for future large-scaled studies for the application of these amino acids in DFU healing, either as prognostic predictors or supplemented regimens.

Abstract
Patients who suffer from cancer are at a higher risk of complications when they experience malnutrition. Evidence shows that oral nutritional supplements favor the healing process. The main objective of this study was to evaluate the efficacy of preoperative oral nutritional intervention in oncological patients undergoing surgery. This study assessed retrospectively 55 cancer patients who previously had undergone abdominal surgery and did not have receive pre-surgical nutritional support (control group), and prospectively 30 oncological patients undergoing gastrointestinal surgery and received pre-surgical high-protein nutritional support (experimental group). All patients had to have a NRS 2002 score ≥ 3. Analytical and clinical parameters were analyzed and the NRS 2002 screening test was performed. Post-operative assessments of surgical wound complications were also carried out to determine the impact of nutrition support. Pre-surgical nutritional interventions reduced the incidence and severity of wound complications as well as the length of hospital stays. Only 26.7% of patients in the experimental group had complications compared to 60% of the control group (P = 0.003). We conclude that pre-surgical nutritional interventions of patients undergoing surgery can improve post-surgical patient outcomes of malnourished patients.

Parenteral amino acid supplementation with high-dose insulin prevents hypoaminoacidemia during cardiac surgery. Nutrition 2019; 69:110566. [PMID: 31539818 DOI: 10.1016/j.nut.2019.110566] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2018] [Revised: 06/26/2019] [Accepted: 07/07/2019] [Indexed: 12/27/2022]
Abstract
OBJECTIVES Surgery triggers a stress response that produces insulin resistance and hyperglycemia. During cardiac surgery, the administration of high-dose insulin along with dextrose titration maintains normoglycemia, but dramatically decreases plasma amino acids (AAs) compared with preoperative fasting levels. Hypoaminoacidemia limits protein synthesis and prevents anabolic responses after surgery. We investigated whether parenteral infusion of AAs during and immediately after cardiac surgery would prevent hypoaminoacidemia in patients who receive high-dose insulin therapy. METHODS Sixteen patients undergoing coronary artery bypass grafting surgery were randomly allocated to receive AAs with % kcal equivalent to either 20% (n = 8) or 35% (n = 8) of their measured resting energy expenditure (REE). Insulin was infused at a constant rate of 5 mU/(kg × min), whereas dextrose was titrated to maintain normoglycemia during and until 5 h after surgery. Plasma AA concentrations were measured at baseline before and after surgery. RESULTS Compared with the 20% AA group after surgery, AA concentrations were significantly higher in the 35% AA group for 12 of 20 AAs (P < 0.032), including all branched-chain AAs. In the 20% AA group, total essential AAs decreased by 21% and nonessential AAs decreased by 14% after surgery compared with preoperative fasting levels. In contrast, giving 35% AAs prevented this unfavorable decrease in AAs, and in fact allowed for a 23% and 12% increase in essential and nonessential AAs, respectively. CONCLUSIONS AA supplementation at 35% REE, but not 20% REE, can effectively prevent hypoaminoacidemia caused by high-dose insulin therapy during cardiac surgery.

Oral administration of EPA-rich oil impairs collagen reorganization due to elevated production of IL-10 during skin wound healing in mice. Sci Rep 2019; 9:9119. [PMID: 31235718 PMCID: PMC6591225 DOI: 10.1038/s41598-019-45508-1] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2019] [Accepted: 03/26/2019] [Indexed: 12/18/2022] Open
Abstract
Wound healing is an essential process for organism survival. Some fatty acids have been described as modulators of wound healing. However, the role of omega-3 fatty acids is unclear. In the present work, we investigate the effects of oral administration of eicosapentaenoic acid (EPA)-rich oil on wound healing in mice. After 4 weeks of EPA-rich oil supplementation (2 g/kg of body weight), mice had increased serum concentrations of EPA (20:5ω-3) (6-fold) and docosahexaenoic acid (DHA; 22:6ω-3) (33%) in relation to control mice. Omega-3 fatty acids were also incorporated into skin in the EPA fed mice. The wound healing process was delayed at the 3rd and 7th days after wounding in mice that received EPA-rich oil when compared to control mice but there was no effect on the total time required for wound closure. Collagen reorganization, that impacts the quality of the wound tissue, was impaired after EPA-rich oil supplementation. These effects were associated with an increase of M2 macrophages (twice in relation to control animals) and interleukin-10 (IL-10) concentrations in tissue in the initial stages of wound healing. In the absence of IL-10 (IL-10-/- mice), wound closure and organization of collagen were normalized even when EPA was fed, supporting that the deleterious effects of EPA-rich oil supplementation were due to the excessive production of IL-10. In conclusion, oral administration of EPA-rich oil impairs the quality of wound healing without affecting the wound closure time likely due to an elevation of the anti-inflammatory cytokine IL-10.

Abstract
Cutaneous injuries, especially chronic wounds, burns, and skin wound infection, require painstakingly long-term treatment with an immense financial burden to healthcare systems worldwide. However, clinical management of chronic wounds remains unsatisfactory in many cases. Various strategies including growth factor and gene delivery as well as cell therapy have been used to enhance the healing of non-healing wounds. Drug delivery systems across the nano, micro, and macroscales can extend half-life, improve bioavailability, optimize pharmacokinetics, and decrease dosing frequency of drugs and genes. Replacement of the damaged skin tissue with substitutes comprising cell-laden scaffold can also restore the barrier and regulatory functions of skin at the wound site. This review covers comprehensively the advanced treatment strategies to improve the quality of wound healing.

Abstract
Immunometabolism is an evolving field of scientific endeavor that merges immunology and metabolism and has provided valuable context when evaluating the influence of dietary interventions on exercise-induced immune dysfunction. Metabolomics, lipidomics, and proteomics provide a system-wide view of the metabolic response to exercise by simultaneously measuring and identifying a large number of small-molecule metabolites, lipids, and proteins. Many of these are involved with immune function and regulation and are sensitive to dietary influences, especially acute carbohydrate ingestion from either sugar beverages or fruits such as bananas. Emerging evidence using large multi-omics data sets supports the combined intake of fruit sugars and phytochemicals by athletes during heavy exertion as an effective strategy to improve metabolic recovery, augment viral defense, and counter postexercise inflammation and immune dysfunction at the cell level. Multi-omics methodologies have given investigators new outcome targets to assess the efficacy of various dietary interventions for physiologically stressed athletes.

Abstract
This study sought to evaluate the potential antioxidative potencies of Chromolaena odorata and Ageratum conyzoides, commonly used herbs in Nigeria for wound first aid and healing. The antioxidant potentials were evaluated by measuring their abilities to scavenge radicals, reduce oxidised iron and quench the formation of lipid peroxides. The findings showed that the extract of Ageratum conyzoides exhibited significantly higher (p<0.05) antioxidant potential than the extract of Chromolaena odorata. The study, therefore, suggests that Ageratum conyzoides has higher potential for therapeutic value than Chromolaena odorata in terms of antioxidant potential.
