Abu-Baker A, Țigăran AE, Peligrad T, Ion DE, Gheoca-Mutu DE, Avino A, Hariga CS, Moraru OE, Răducu L, Jecan RC. Exploring an Innovative Approach: Integrating Negative-Pressure Wound Therapy with Silver Nanoparticle Dressings in Skin Graft Procedures. J Pers Med 2024; 14:206. [PMID: 38392639 PMCID: PMC10890209 DOI: 10.3390/jpm14020206] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2024] [Revised: 02/04/2024] [Accepted: 02/09/2024] [Indexed: 02/24/2024] Open
Abstract
BACKGROUND Skin grafting is a helpful instrument in a plastic surgeon's arsenal. Several types of dressings were designed to facilitate the process of graft integration. Negative-pressure wound therapy is a proven dressing method, enhancing graft survival through several mechanisms: aspiration of secretions, stimulation of neoangiogenesis, and promotion of an anti-inflammatory environment. Silver nanoparticle dressings also bring multiple benefits by bearing an antimicrobial effect and providing a humid medium, which are favorable for epithelialization. The combination of NPWT (negative-pressure wound therapy) with AgNPs (silver nanoparticles) has not been widely studied. MATERIALS AND METHODS This study aimed to compare the outcomes of silver nanoparticle sheets with the combination of negative-pressure wound therapy and silver nanoparticle dressings. We conducted a comparative prospective study on 80 patients admitted to the Plastic Surgery Department of "Prof. Dr. Agrippa Ionescu" Emergency Clinical Hospital between 1st of January 2020 and 31st of December 2022. The study population was randomized to receive either silver nanoparticle dressings or negative-pressure wound therapy (NPWT) combined with silver nanoparticle dressings. Various parameters were monitored, including patient comorbidities and graft-related data such as defect etiology, graft integration, and graft size. Dressings were changed, and graft status was evaluated at 7, 10, and 14 days postoperatively. Additionally, baseline C-reactive protein (CRP) levels were measured before surgery and 7, 10, and 14 days postoperatively. RESULTS The study demonstrated an enhanced integration of skin grafts at all evaluation stages when employing NPWT combined with AgNPs, particularly evident 10 days post operation. Significant variations in graft integration were also observed based on factors such as diabetes, cardiovascular disease, graft size, or the origin of the grafted defect. Moreover, dynamic C-reactive protein monitoring showed a statistically significant decrease in CRP levels 10 days post operation among patients treated with NPWT in conjunction with silver dressing, consistent with the nearly complete integration of skin grafts at this evaluation threshold. CONCLUSION Several factors influence the postoperative evolution of split-skin grafts. Postoperative dressings target local factors to enhance graft integration further. Our research demonstrated that the innovative combination of NPWT-assisted dressings, complemented by a silver nanoparticle sheet, resulted in improved benefits for graft integration and the alleviation of systemic inflammation.

Abstract
BACKGROUND Surgical site infection (SSI) is a major complication of pediatric cardiac surgery. If the risk of developing SSI can be predicted based on the patient's preoperative background, appropriate preoperative management to prevent the development of SSI can be achieved. METHODS We retrospectively studied cases for patients younger than 7 years of age among surgeries performed through a median sternotomy at Kagoshima University Hospital from April 2011 to March 2021. SSI was diagnosed according to the Centers for Disease Control and Prevention guidelines and classified into 3 types: superficial incisional SSI (SiSSI), deep incisional SSI (DiSSI) and mediastinitis. RESULTS Of the 765 consecutive pediatric cardiac surgeries, 597 were included in the analysis based on the exclusion criteria. Of these, 17 (2.8%) developed SSI (3 SiSSI cases, 2 DiSSI cases and 12 mediastinitis cases), with Staphylococcus aureus as the major pathogen. Univariate analysis revealed that low preoperative serum protein ( P = 0.049) and low serum albumin levels ( P = 0.023) were risk factors for the development of SSI. No findings suggested impaired hepatic synthesis, inflammatory disease or protein loss from the kidney or intestinal tract. We concluded that malnutrition caused low serum protein and albumin levels. CONCLUSIONS Low preoperative serum protein and albumin levels are risk factors for SSI development of SSI. Nutritional status should be regularly assessed in children scheduled for cardiac surgery, and interventions, such as nutritional guidance, should be considered if malnutrition is suspected.

Abstract
ZUSAMMENFASSUNGBei einer Störung im Ablauf der Wundheilung kann es zu einem verzögerten oder fehlenden Wundverschluss kommen. Als ein möglicher Störfaktor gilt die Ernährung. Man muss zwischen quantitativer und qualitativer Mangelernährung unterscheiden. Gerade übergewichtige Patienten leiden oft an einer qualitativen Mangelernährung und Sarkopenie.Spezifische Erkrankungen machen eine entsprechende diätetische Nahrungsempfehlung notwendig. So findet man bei dialysepflichtigen Patienten, Dekubitus-Patienten und Ulcus cruris-Patienten oft einen Eiweißmangel. Auch niedrige Level an Vitamin C, Zink, Folsäure, Vitamin D oder Spurenelementen können die Wundheilung negativ beeinflussen.Größere prospektive Studien sollten klären, ob eine Substitution dieser Mangelzustände den gewünschten positiven Effekt auf die Wundheilung hat. Es erscheint aber sinnvoll, eine ausgewogene Ernährung und an die individuellen Ernährungsgewohnheiten angepasste Verbesserung der Aufnahme von Vitaminen, Spurenelementen und Eiweißen anzustreben.

Development of a textile based protein sensor for monitoring the healing progress of a wound. Sci Rep 2022; 12:7972.

Abstract
This article focuses on the design and fabrication of flexible textile-based protein sensors to be embedded in wound dressings. Chronic wounds require continuous monitoring to prevent further complications and to determine the best course of treatment in the case of infection. As proteins are essential for the progression of wound healing, they can be used as an indicator of wound status. Through measuring protein concentrations, the sensor can assess and monitor the wound condition continuously as a function of time. The protein sensor consists of electrodes that are directly screen printed using both silver and carbon composite inks on polyester nonwoven fabric which was deliberately selected as this is one of the common backing fabric types currently used in wound dressings. These sensors were experimentally evaluated and compared to each other by using albumin protein solution of pH 7. A comprehensive set of cyclic voltammetry measurements was used to determine the optimal sensor design the measurement of protein in solution. As a result, the best sensor design is comprised of silver conductive tracks but a carbon layer as the working and counter electrodes at the interface zone. This design prevents the formation of silver dioxide and protects the sensor from rapid decay, which allows for the recording of consecutive measurements using the same sensor. The chosen printed protein sensor was able to detect bovine serum albumin at concentrations ranging from 30 to 0.3 mg/mL with a sensitivity of \documentclass[12pt]{minimal}

Abstract
BACKGROUND & AIMS This systematic review sought to identify and summarize existing evidence for the impact of nutrition on the development, progression, and outcomes of peripheral artery disease (PAD). METHODS We performed a systematic literature search of available studies published between January 1974 and December 2019. Randomized controlled trials (RCT), observational studies, and cross-sectional studies reporting either the primary or secondary prevention of PAD with nutritional intake were included. The quality assessment was performed for the RCTs, without pooling a meta-risk estimate. RESULTS Among a total of 8502 records screened, 186 full texts were assessed for eligibility, and 82 studies (30% RCT) were analyzed. The nutrients were structured in fruits, vegetables and antioxidants, fats and oils, dietary fiber, meat, proteins, vitamins and trace elements, and diets and lifestyle. The findings of the current systematic review indicate that the Mediterranean diet, nuts, and polyunsaturated fat are associated with a lower incidence of PAD and saturated fat, cholesterol, and processed meat were associated with higher rates of cardiovascular events in patients suffering from PAD. CONCLUSIONS The current review found evidence of a beneficial impact of the Mediterranean diet including nuts in this target population. More RCTs and high-quality registries are needed that focus on nutritional habits among patients with PAD to design appropriate preventive programs.

Abstract
Wound healing is a complex and energy-demanding process. The relationship between nutrition and wound healing has been recognized for many centuries. Several studies have indicated that nutritional deficiencies are more prevalent among patients with chronic wounds. Malnutrition may alter the inflammatory response, collagen synthesis, and wound tensile strength, all of which are crucial for wound healing. Although the specific role of nutrition and supplementation in wound care remains uncertain, it is necessary to identify and correct nutritional imbalances to avoid any potential deterioration of the healing process. It is also important to recognize the differences in pathophysiology between acute and chronic wounds. A burn, surgical, or a traumatic wound is different from a diabetic foot ulcer, which is different from a pressure ulcer. Chronic wounds are more prevalent in the aging population, and patients often have underlying comorbidities, such as diabetes mellitus, peripheral vascular disease, connective tissue disease, or other systemic illnesses that may alter energy metabolism and contribute to impaired healing. Management approaches to acute wound care may not apply universally to chronic wounds. In this review, we discuss the available data and possible roles for nutrition in wound healing.

Abstract
Wound healing is an intricate, tightly regulated process that is critical to maintaining the barrier function of skin along with preserving all other skin functions. This process can be influenced by a variety of modifiable and nonmodifiable factors. As wound healing takes place in all parts of the human body, this review focuses on cutaneous wound healing and highlights the classical wound healing phases. Alterations in any of these phases can promote chronic wound development and may impede wound healing.

Abstract
BACKGROUND This review aims to identify and review the current evidence for preventing postoperative surgical site infections in abdominal aortic aneurysm surgery or infrainguinal arterial surgery. METHODS Extended literature review of clinical trials that examined the prevention of postoperative surgical site infections in abdominal aortic aneurysm or infrainguinal arterial surgery. Searches were conducted on Ovid MEDLINE (1950 - 13 March 2020) using key terms for vascular surgery, surgical site infections and specific preventative techniques. Articles were included if they discussed a relationship between a preventative technique and surgical site infections in abdominal aortic aneurysm or infrainguinal arterial surgery. The GRADE guidelines were used to assess the quality of evidence. RESULTS 21 techniques and 81 studies were included. Prophylactic antibiotics and negative pressure wound therapy have a high quality of evidence for the prevention of surgical site infections in abdominal aortic aneurysm or infrainguinal arterial surgery. A moderate quality evidence base was identified for gentamicin containing collagen implant (confined to high surgical site infection risk centers). Currently, there is a low or very low quality of evidence to suggest a reduction in the surgical site infection rate for combination therapy, glycaemic control, Methicillin-resistant Staphylococcus aureus screening and absorbable suture. Evidence suggests no beneficial effect for nutritional supplementation, chlorhexidine bath, hair removal therapy, Staphylococcus aureus nasal eradication, cyanoacrylate microsealant, silver grafts, rifampicin bonded grafts, triclosan coated suture and postoperative wound drains. Endoscopic saphenous vein harvest may reduce surgical site infection rate (very low quality of evidence) but may lower long-term patency. Autologous vein grafts may increase surgical site infections (very low quality of evidence) but may provide better long-term patency rates in above-knee infrainguinal bypass surgery. There was no identified evidence for perioperative normothermia, electrosurgical bipolar vessel sealer or Dermabond and Tegaderm for surgical site infection prevention in vascular surgery. CONCLUSIONS Prophylactic antibiotics and postoperative negative pressure wound therapy are effective in the prevention of postoperative surgical site infection in abdominal aortic aneurysm or infrainguinal arterial surgery. There exists a significant risk of bias in the literature for many preventative techniques and further studies are required to investigate the efficacy of gentamicin containing collagen implant, and specific combination therapies.

Abstract
Chronic leg ulcers are a common condition among adults, causing pain and social distress. Population aging has contributed to the amplification of the disease with increased cardiovascular diseases such as myocardial infarction, stroke, limb ischemia, cancers, chronic respiratory diseases, and diabetes. The aim of this study was to evaluate the influence of the Mediterranean Diet (MD) and hydration on the healing rate of the ulcers. A group of 35 patients (M/F 16/19, mean age 78 ± 10 years) with venous, arterial, or mixed ulcers was subjected to a Food Frequency Questionnaire (FFQ) and a Hydration Habits Questionnaire (HHQ). Clinical and anthropometric data were collected. A one-year follow-up was conducted. Complete ulcer healing was observed in 26% of the patients, of whom 67% had a habit of high hydration (more than 1 liter /day), regardless of adherence to the MD. In our study population, about half showed a low adherence to the MD. A moderate-high adherence to the MD showed an increase of arterial ulcer healing compared to subjects with a low adherence to the MD, however, only when associated to a consumption of more than 1 liter of water daily. In conclusion, dietary assessments could help identify patients who are likely to benefit from nutritional interventions for improving overall health and wound healing. The habit of high hydration, namely more than 1 liter daily, can influence the wound healing rate.

Abstract
Medication-related osteonecrosis of the jaw (MRONJ) is a potentially severe side effect of mostly antiresorptive drugs. The aim of this prospective clinical study was to evaluate the nutritional status in MRONJ patients scheduled for surgical treatment (intraoral soft tissue closure). The following parameters were evaluated: body weight, body height, BMI, nutritional risk index (NRI), bioelectric impedance analysis (BIA), vitamins A, B12, D3, E, K1, folic acid, iron, total protein, transferrin, ferritin, prealbumin, albumin, and zinc. All subjects were admitted to hospital four to five days before surgery and sip-fed with Nutritia Fortimel Compact Protein in addition to regular oral food intake. During surgery, a nasogastric tube was inserted and only removed on hospital discharge five days postoperatively. A total of 58 patients could be included. Half of the MRONJ patients were identified to be at risk for malnutrition. Deficiencies regarding protein levels were revealed, whereas hardly any relevant deficits of micronutrients were noted. The intraoral wound healing four weeks post-surgery was highly satisfactory with a low dehiscence rate of intraoral mucosal sites. Of all parameters analyzed, the dehiscence rate at the last follow-up four weeks post-surgery was significantly influenced by vitamin K, transferrin, and ferritin levels (p = 0.030, p = 0.004, and p = 0.023, respectively). In conclusion, perioperative dietary counselling and appropriate nutritional therapy are important supportive measures in MRONJ patients scheduled for intraoral soft tissue closure.

Abstract
OBJECTIVE To describe the dietary habits and anthropometric and biochemical parameters of patients with active venous leg ulcers and to verify the association of these variables with wound duration and area. DESIGN, SETTING, AND PARTICIPANTS A cross-sectional study conducted with 33 participants diagnosed with venous leg ulcers in outpatient care. MAIN OUTCOME MEASURES Socioeconomic data, anthropometric parameters, biochemical parameters, food consumption, and wound characteristics were analyzed by an interprofessional team. MAIN RESULTS Participants were an average of 58 ± 13 years, 57.6% women, 84.8% overweight, and had a median wound duration of 10 months (range, 1-192 months) and an average wound area of 5 cm (range, 0.22-61.1 cm). Diets were typically hypocaloric and hypoproteic, with a low amount of vitamin A and magnesium. Wound duration was negatively associated with polyunsaturated fat intake (P = .032), whereas wound area was significantly associated with lipid intake (P = .002) and C-reactive protein (P = .040). CONCLUSIONS Patients with active venous leg ulcers were overweight (leading to systemic inflammation) and had low consumption of calories, protein, and micronutrients that could support cicatrization. Wound area was associated with a high-fat diet, whereas wound duration was negatively associated with polyunsaturated fat intake.

Abstract
Malnutrition is a negative confounding factor influencing wound healing. The prevalence of malnutrition increases with age, as do chronic wounds. The aim of this prospective study was to analyse the nutritional status of patients with chronic wounds. Data collection of sociodemographic and nutritional parameters was based on an inter‐professionally developed questionnaire as well as the Mini Nutritional Assessment (MNA). A total of 90 patients with chronic wounds of different aetiologies were included. Pain and dental health were found to be significant factors: Patients with malnutrition or the risk of malnutrition had significantly lower tooth and oral health scores (rs = −0.218, P = .039), and higher pain levels at rest (rs = 0.339, P < .001), while dressing (rs = 0.268, P = .014), and upon exercising (rs = 0.303, P = .005). Our data address the impact of nutrition on chronic wounds and confirm the relationship between pain, dental health, and nutritional status. Clinicians should be aware of adequate pain management and dental health care in chronic wound patients. Further studies, particularly on characterisation of preventive and therapeutic measures in the nutrition of chronic wound patients, are of great importance.

Yang F, Qin X, Zhang T, Zhang C, Lin H. Effect of Oral Administration of Active Peptides of Pinctada Martensii on the Repair of Skin Wounds. Mar Drugs 2019; 17:md17120697. [PMID: 31842313 PMCID: PMC6950544 DOI: 10.3390/md17120697] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2019] [Revised: 12/05/2019] [Accepted: 12/10/2019] [Indexed: 12/16/2022] Open
Abstract
Skin wound healing, especially chronic wound healing, is a common challenging clinical problem. It is urgent to broaden the sources of bioactive substances that can safely and efficiently promote skin wound healing. This study aimed to observe the effects of active peptides (APs) of the mantle of Pinctada martensii on wound healing. After physicochemical analysis of amino acids and mass spectrometry of APs, the effect of APs on promoting healing was studied through a whole cortex wound model on the back of mice for 18 consecutive days. The results showed that APs consisted of polypeptides with molecular weights in the range 302.17–2936.43 Da. The content of polypeptides containing 2–15 amino acids accounted for 73.87%, and the hydrophobic amino acids accounted for 56.51%. Results of in vitro experimentation showed that mice in APs-L group which were fed a low dose of APs (0.5 g/kg bw) had a shortened epithelialization time due to a shortening inflammatory period (p < 0.05). Mechanistically, this relied on its specific ability to promote the proliferation of CD31, FGF and EGF which accelerated the percentage of wound closure. Moreover, the APs-L group mice had enhanced collagen synthesis and increased type III collagen content in their wounds through a TGF-β/Smad signaling pathway (p > 0.05). Consequently, scar formation was inhibited and wound healing efficiency was significantly improved. These results show that the APs of Pinctada martensii promote dermal wound healing in mice and have tremendous potential for development and utilization in skin wound healing.

Abstract
Skin wound healing, especially chronic wound healing, is a common challenging clinical problem. It is urgent to broaden the sources of bioactive substances that can safely and efficiently promote skin wound healing. This study aimed to observe the effects of small molecular peptides (SMPs) of the mantle of Pinctada martensii on wound healing. After physicochemical analysis of amino acids and mass spectrometry of SMPs, the effect of SMPs on promoting healing was studied through a whole cortex wound model on the back of mice for 18 consecutive days. The results showed that SMPs consisted of polypeptides with a molecular weight of 302.17-2936.43 Da. The content of polypeptides containing 2-15 amino acids accounted for 73.87%, and the hydrophobic amino acids accounted for 56.51%. Results of in vitro experimentation showed that SMPs possess a procoagulant effect, but no antibacterial activity. Results of in vivo experiments indicated that SMPs inhibit inflammatory response by secretion of anti-inflammatory factor IL-10 during the inflammatory phase; during the proliferative phase, SMPs promote the proliferation of fibroblasts and keratinocytes. The secretion of transforming growth factor-β1 and cyclin D1 accelerates the epithelialization and contraction of wounds. In the proliferative phase, SMPs effectively promote collagen deposition and partially inhibit superficial scar hyperplasia. These results show that SMPs promotes dermal wound healing in mice and have a tremendous potential for development and utilization in skin wound healing.

JOURNAL DE MÉDECINE VASCULAIRE 2018; 43:225-230. [PMID: 29981730 DOI: 10.1016/j.jdmv.2018.05.006] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/09/2018] [Accepted: 05/09/2018] [Indexed: 11/26/2022]
Abstract
OBJECTIVES This study was conducted to determine hemodynamic and clinical tolerance under short-stretch compression therapy in elderly patients suffering from mixed-etiology leg ulcers. DESIGN Transversal observational study conducted in 25 hospitalized patients with a moderate peripheral arterial occlusive disease defined as an ankle-brachial pressure index>0.5, an ankle pressure of>70mmHg and a toe cuff pressure (TP)>50mmHg. MATERIAL AND METHODS Short-stretch bandages were applied daily with pressures from 20 to 30mmHg. Ankle-brachial pressure, great toe laser Doppler flowmetry (LDF) and transcutaneous oxygen pressure (TcPO2) on dorsum of the foot were measured at baseline and after its removal at 24hours. Great toe LDF was also measured at 10minutes after bandage application. Compression pressure (CP) was measured with a sub-bandage device at baseline, at 10minutes and before bandage removal at 24hours. Clinical tolerance was evaluated taking into account the patient's pain and skin tolerance. RESULTS Mean age of patients was 80±15 years. Median duration of ulcers was 18 months. Hypertension was highly prevalent. One third of patients had diabetes. Toe pressure index and TcPO2 values did not significantly change under compression therapy (P=0.51 and P=0.09, respectively) whereas CP decreased significantly during 24hours. The loss of CP was significant 10minutes after bandage application (P<0.001). Nearly all ulcers were painful prior to placement of compression therapy and required level 1 analgesics. One patient required level 2 analgesic for pain relief. No increase in pain and no ischemic skin damage occurred under compression therapy. CONCLUSIONS In elderly patients with mixed leg ulcers and with an absolute TP>50mmHg, short-stretch compression of up to 30mmHg does not adversely affect arterial flow and appears clinically well tolerated. Such bandages with appropriate levels of compression may aid ulcer healing by treating the venous part of the disease.

Abstract
PURPOSE OF REVIEW Ankle fractures and diabetes mellitus are both increasing in prevalence. Patients with both diabetes and an ankle fracture have been shown to have an increased rate of complications which can be catastrophic. The purposes of this review are to identify factors placing patients at an increased risk and offer guidance on the management of these injuries, in order to reduce potential complications. RECENT FINDINGS Non-operative management of unstable ankle fractures in patients with diabetes results in an unacceptably high rate of complications. Operatively managed patients with uncomplicated diabetes seem to fair as well as patients without diabetes. Thus, it is important to recognize patients as either complicated or uncomplicated at the onset of their treatment based on comorbidities. There is limited evidence to guide the management of ankle fractures in patients with diabetes, in particular those deemed complicated. Non-operative management of unstable fractures in diabetic patients should be avoided.

Abstract
OBJECTIVE Impaired or delayed wound healing is a common health problem. However, it remains challenging to predict whether wounds in patients will heal without complication or will have a prolonged healing time. In this study, the authors developed an objective screening tool to assess wound healing using microscopic quantification of reepithelialization in a split-thickness skin graft wound model and used this tool to identify risk factors for defective wound healing. DESIGN Thirty patients (16 male and 14 female) were included in this prospective study. Anterior thigh skin biopsies from the donor site region of partial-thickness skin grafts were dressed with moisture-retentive dressings, and biopsies were examined on days 0, 2, 5, and 10 postoperatively by microscopy. Images were then transferred to a computer for image analysis and epithelial measurements (epithelial thickness and total reepithelialized surface). The effects of gender, age, body mass index, and smoking behavior on these wound healing parameters were determined. RESULTS The authors found comparable results for the computer and traditional measure methods. However, the time required to perform the measurements using the semiautomated computer method was less than half the time of the traditional method. Image capturing, enhancing, and analysis with the new method required approximately 2 minutes 30 seconds, whereas the traditional methods took up to 7 minutes per image. The total size of the reepithelialized surface (P = .047) and percentage of the biopsy resurfaced with epithelia (P = .011) at day 10 were both significantly higher in male patients compared with female patients. In patients younger than 55 years, reepithelialized areas were significantly thicker than in patients older than 55 years (P = .008), whereas the size of the reepithelialized surface showed no differences. No significant differences in reepithelialization parameters were found concerning body mass index and smoking behavior. CONCLUSIONS Both male gender and older age impair reepithelialization rate and epithelial thickness in partial-thickness skin graft donor site wounds. In contrast, body mass index and smoking behavior have not been shown to be influencing factors on reepithelialization. Thus, microscopic quantification of reepithelialization might be a suitable method for predicting complications associated with wound healing.

Abstract
Wound assessment is usually performed in hospitals or specialized labs. However, since patients spend most of their time at home, a remote real time wound monitoring would help providing a better care and improving the healing rate. This review describes the advances in sensors and biosensors for monitoring the concentration of C-reactive protein (CRP), temperature and pH in wounds. These three parameters can be used as qualitative biomarkers to assess the wound status and the effectiveness of therapy. CRP biosensors can be classified in: (a) field effect transistors, (b) optical immunosensors based on surface plasmon resonance, total internal reflection, fluorescence and chemiluminescence, (c) electrochemical sensors based on potentiometry, amperometry, and electrochemical impedance, and (d) piezoresistive sensors, such as quartz crystal microbalances and microcantilevers. The last section reports the most recent developments for wearable non-invasive temperature and pH sensors suitable for wound monitoring.

Abstract
The association between malnutrition, impaired wound healing, and the presence of chronic wounds has been recognized for a long time. It is widely believed that the lack of adequate nutrition increases the risk of developing wounds which have a great likelihood of progressing to chronicity due to lack of appropriate healing responses. This risk is particularly high in the aging population. For the individual patient, as well as patient populations, the diagnosis of malnutrition has been in dispute; further, there is lack of agreement of when and how to intervene nutritionally in those with wounds or healing deficits. This article examines the relationship of nutritional status with the presence and clinical evolution of leg ulcers in humans, focusing on diabetic and venous leg ulcers; we will further review the effect of nutritional therapy on the outcome of these ulcers.

Abstract
AIMS To identify the associations and effects of nutritional characteristics and interventions on ulcer outcomes in adult patients with venous leg ulcers. BACKGROUND Venous leg ulcers are the most prevalent type of lower limb ulcer; however, little evidence exists regarding the relationship between nutritional status and ulcer healing. DESIGN A systematic search of English language articles was conducted using the Cochrane Collaboration Handbook for Systematic Reviews of Interventions. DATA SOURCES A search of databases Ovid MEDLINE, EMBASE, Cochrane, CINAHL and Scopus was performed for studies published between January 2004 - May 2017. REVIEW METHODS Quality of the included studies was assessed using the Cochrane Collaboration's Risk of Bias Assessment tool and the relevant Joanna Briggs Institute quality appraisal checklists. RESULTS Twenty studies met the inclusion criteria. All participants had Clinical Aetiology Anatomy Pathophysiology classification C5 (healed) or C6 (active) ulcers. Studies were conducted in a range of clinical settings with relatively small sample sizes. The majority of patients were overweight or obese. Increased body mass index was associated with delayed wound healing. Vitamin D, folic acid and flavonoids were associated with some beneficial effects on ulcer healing. Dietary intakes of omega-3 fatty acids, vitamin C and zinc were low for some patients. CONCLUSION Current evidence suggests that venous leg ulcer patients are more likely to be overweight or obese. However, evidence for weight management improving wound healing is lacking. Micronutrients, including vitamin D and folic acid, may improve wound healing in at-risk patients.

Abstract
BACKGROUND Studies investigating the nutritional status of patients with leprosy and plantar ulcers are sparse. Therefore, the objective of this study was to describe the protein profile of leprosy patients with plantar ulcers from the Eastern Amazon region. METHODS A case record form was created for 75 patients with leprosy (31 with plantar ulcers and 44 without plantar ulcers) with the following data: sociodemographic characteristics, clinical form of leprosy, presence or absence of plantar ulcers, and nutritional assessment using anthropometry consisting of the measurement of body mass index, arm circumference, arm muscle circumference, and triceps skinfold. Levels of blood albumin, transferrin, and C-reactive protein (CRP) were also measured. Data regarding protein intake were obtained using a Food Frequency Questionnaire. RESULTS Plantar ulcers occurred more frequently in male patients (67.7%), patients aged 40-49 years (mean ± SD: 47.3 ± 8.0 years), and patients receiving 300 or 600 USD (71.0%). The mean weight and height of patients were 71.6 ± 11.4 kg and 1.62 ± 0.1 m, respectively. High levels of CRP were detected in 51.6% of leprosy patients with plantar ulcers and only 9.1% of patients without plantar ulcers (P < 0.001). Nutritional depletion of transferrin was observed in 14.3% of patients with paucibacillary leprosy and 44.3% of patients with multibacillary leprosy (P = 0.0447). Most patients had normal levels of serum albumin (74.2% with plantar ulcers and 77.3% without plantar ulcers). CONCLUSIONS Most leprosy patients with plantar ulcers have normal levels of serum albumin and transferrin and high CRP levels, which indicates the presence of an inflammatory process. Our findings suggest the need to monitor patients with leprosy to prevent the occurrence of plantar ulcers and to provide adequate treatment for patients with existing plantar ulcers.

Abstract
Background/objectives Venous ulcers carry psychological and high financial burden for patients, causing depression, pain, and limitation of mobility. The study aimed to identify factors associated with an increased risk of venous ulceration in patients with varicose veins in Armenia. Methods A case-control study design was utilized enrolling 80 patients in each group, who underwent varicose treatment surgery in two specialized surgical centers in Armenia during 2013–2014 years. Cases were patients with varicose veins and venous leg ulcers. Controls included patients with varicose veins but without venous leg ulcers. Data were collected using interviewer-administered telephone interviews and medical record abstraction. Multiple logistic regression analysis was used to identify the risk factors of venous ulceration. Results There were more females than males in both groups (72.5% of cases and 85.0 % of controls). Cases were on average older than controls (53.9 vs. 39.2 years old, p ≤ 0.001). After adjusting for potential confounders, the estimated odds of developing venous ulcer was higher in patients with history of post thrombotic syndrome (odds ratio = 14.90; 95% confidence interval: 3.95–56.19; p = 0.001), with higher average sitting time (odds ratio = 1.32 per hour of sitting time; 95% confidence interval: 1.08–1.61; p = 0.006), those with reflux in deep veins (odds ratio = 3.58; 95% confidence interval: 1.23–10.31; p = 0.019) and history of leg injury (odds ratio = 3.12; 95% confidence interval: 1.18–8.23; p = 0.022). Regular exercise in form of walking (≥5 days per week) was found to be a protective factor from venous ulceration (odds ratio = 0.26; 95% confidence interval: 0.08–0.90; p = 0.034). Conclusion We found that reflux in deep veins, history of leg injury, history of post thrombotic syndrome, and physical inactivity were significant risk factors for venous ulceration in patients with varicose veins, while regular physical exercise mitigated that risk. Future studies should investigate the relationships between the duration and type of regular exercise and the risk of venous ulceration to make more specific recommendations on preventing ulcer development.

J Diabetes Res 2017; 2017:5797194.

Abstract
Objective. Patients with diabetic foot ulcers undergoing amputations have poor prognosis. Malnutrition usually occurs in this population and is associated with increased risk of mortality. The geriatric nutritional risk index (GNRI) is a widely used, simple, and well-established tool to assess nutritional risk. The purpose of this study was to assess the association between GNRI and all-cause mortality in diabetic foot ulcers patients undergoing minor or major amputations. Methods. This was a retrospective cohort study including 271 adult patients. Patients were divided into two groups according to a GNRI cutoff value of 92, and characteristics and mortality were compared between the two groups. Cox proportional hazard analysis was performed to explore the association between GNRI and mortality. Result. GNRI (p < 0.001), age (p < 0.001), and eGFR (p = 0.002) were independent predictors of mortality. Among a subgroup of 230 patients with minor amputation, increased age (p < 0.001), coronary artery disease (p = 0.030), and increased GNRI (p < 0.001) were major risk factors. Conclusion. GNRI on admission might be a novel clinical predictor for the incidence of death in patients with diabetic foot ulcers who were undergoing amputations.

Abstract
OBJECTIVE To determine if preoperative hypoalbuminemia is associated with postoperative wound complications among patients with vulvar cancer. METHODS The National Surgical Quality Improvement Program database was queried for cases of vulvar cancer undergoing vulvectomy with or without lymphadenectomy (LND) from 2008 to 2013. Primary outcome was major wound complication. Secondary outcome was minor wound complication. Hypoalbuminemia was defined as albumin<3.5g/dL. Descriptive statistics and multivariable logistic regression were used for analysis. RESULTS Of 777 vulvar cancer patients, 514 (66.2%) had vulvar surgery alone and 263 (30.3%) had a LND. Median age was 66 (range 20-90) and median BMI was 28.9kg/m(2) (range 14.3-65.5). The incidence of wound complication was 10.4% (81/777) with 48 minor and 39 major complications. There was no difference in major wound complications when a LND was performed (p=1.0). Preoperative albumin was recorded in 429 patients (55.2%). Patients with hypoalbuminemia were more likely to have a major wound complication (OR 2.9 95% CI 1.1-7.3, p=0.02), even after adjusting for BMI, age, preoperative hematocrit, and diabetes (aOR 2.7 95% CI 1.1-7.1, p=0.04). In bivariable analysis, age, diabetes, and BMI were not associated with wound complication. Patients with a wound infection had 10 times the odds of being readmitted within 30days (OR 9.5, 95% CI 4.9-18.4, p<0.01). CONCLUSIONS Low preoperative albumin is associated with major postoperative wound complications in women undergoing surgery for vulvar cancer. When obtaining informed consent, patients with low albumin should be counseled regarding higher risks of postoperative wound complication.

Abstract
The purpose of this cross-sectional descriptive pilot study was to describe daily intake of select nutrients important for efficient wound healing and general health in a sample of older adults (64.25 ± 9.49 years of age) with chronic venous leg ulcers (CVLUs; N = 12), compared to recommended dietary allowances (RDA). Anthropometric data were also collected. Compared to RDA, participants on average consumed lower vitamin C (60.03 ± 49.73 mg/d) and higher sodium (3197.07 ± 1455.04 mg/d), sugar (181.21 ± 115.45 g/d), and saturated fat (33.75 ± 1.06 g/d). They also demonstrated a relatively high plasma n-6/n-3 polyunsaturated fatty acid ratio, a biomarker of inflammation (11.25 ± 1.99). The mean body mass index indicated extreme obesity (41.48 ± 11.47). A multidisciplinary treatment approach that includes routine dietary assessments followed by tailored dietary interventions may improve wound healing and long-term health outcomes in this population.

Abstract
Older adults are more likely to have chronic wounds than younger people, and the effect of chronic wounds on quality of life is particularly profound in this population. Wound healing slows with age, but the basic biology underlying chronic wounds and the influence of age-associated changes on wound healing are poorly understood. Most studies have used in vitro approaches and various animal models, but observed changes translate poorly to human healing conditions. The effect of age and accompanying multimorbidity on the effectiveness of existing and emerging treatment approaches for chronic wounds is also unknown, and older adults tend to be excluded from randomized clinical trials. Poorly defined outcomes and variables; lack of standardization in data collection; and variations in the definition, measurement, and treatment of wounds also hamper clinical studies. The Association of Specialty Professors, in conjunction with the National Institute on Aging and the Wound Healing Society, held a workshop, summarized in this article, to explore the current state of knowledge and research challenges, engage investigators across disciplines, and identify research questions to guide future study of age-associated changes in chronic wound healing.

Abstract
Significance: Wound-healing complications are a clinical problem with a considerable socioeconomic burden. Since several nutrients play a physiological role in wound healing, supplementation of these nutrients may improve wound healing. Recent Advances: Oral nutritional supplements and enteral formulas providing arginine, glutamine, and micronutrients such as ascorbic acid and zinc should improve the healing of pressure ulcers (PU) and the healing of surgical, traumatic, and burned wounds. Is their efficacy proved from clinical intervention trials? Critical Issues: Formulas that are rich in energy, protein, arginine, vitamin C, and zinc can improve PU healing, whereas their efficacy for PU prevention is less clear. High-dose supplementation of vitamin C, zinc, and pantothenic acid may improve the healing of surgical wounds in healthy subjects. Arginine lowers the risk of fistulas in patients undergoing elective surgery due to gastrointestinal cancer. However, formulations also enriched with n-3-fatty acids and ribonucleic acids lower the risk of several wound complications, thus being more effective than isolated arginine. Glutamine and antioxidant micronutrients (vitamin C and E, zinc, selenium, and copper) can improve the healing of surgical, traumatic, and burned wounds. Future Directions: Considerable evidence suggests that formulations, indicated especially for critically ill patients, support the healing of PU and the healing of surgical and burned wounds. However, their optimal composition with regard to the dose of individual components has to be determined in future studies. Further well-designed trials should investigate the impact of certain nutrients for the prevention of PU and for the healing of surgical wounds in healthy subjects.

Abstract
Significance: Nutrition is one of the most basic of medical issues and is often ignored as a problem in the management of our chronic wound patients. Unfortunately, malnutrition is widespread in our geriatric patients even in nursing homes in developed countries. Attention to basic nutrition and providing appropriate supplements may assist in the healing of our chronic wounds. Recent Advances: Recent research has revealed the epidemiology of malnutrition in developed countries, the similarities to malnutrition in developing countries, and some of the physiologic and sociologic causes for this problem. More information is now available on the biochemical effects of nutrient deficiency and supplementation with macronutrients and micronutrients. In some cases, administration of isolated nutrients beyond recommended amounts for healthy individuals may have a pharmacologic effect to help wounds heal. Critical Issues: Much of the knowledge of the nutritional support of chronic wounds is based on information that has been obtained from trauma management. Due to the demographic differences of the patients and differences in the physiology of acute and chronic wounds, it is not logical to assume that all aspects of nutritional support are identical in these patient groups. Before providing specific nutritional supplements, appropriate assessments of patient general nutritional status and the reasons for malnutrition must be obtained or specific nutrient supplementation will not be utilized. Future Directions: Future research must concentrate on the biochemical and physiologic differences of the acute and chronic wounds and the interaction with specific supplements, such as antioxidants, vitamin A, and vitamin D.

Abstract
The aim of this study was to evaluate the effect of silk sericin, a protein from silkworm cocoon, on scratch wound healing in vitro. For applicable result in clinical use, we also study the efficacy of sericin added to a standard antimicrobial cream, silver zinc sulfadiazine, for open wound care in the treatment of second-degree burn wounds. In vitro scratch assays show that sericin at concentration 100 μg/mL can promote the migration of fibroblast L929 cells similar to epidermal growth factor (positive control) at 100 μg/mL. After 1 day of treatment, the length of scratch in wounds treated with sericin was significantly shorter than the length of negative control wounds (culture medium without sericin). For clinical study, a total of 29 patients with 65 burn wounds which covered no less than 15 % of total body surface area were randomly assigned to either control (wounds treated with silver zinc sulfadiazine cream) or treatment (wounds treated with silver zinc sulfadiazine with added sericin cream) group in this randomized, double-blind, standard-controlled study. The results showed that the average time to reach 70 % re-epithelialization of the burned surface and complete healing in the treatment group was significantly shorter, approximately 5-7 days, than in the control group. Regarding time for complete healing, control wounds took approximately 29.28 ± 9.27 days, while wounds treated with silver zinc sulfadiazine with added sericin cream took approximately 22.42 ± 6.33 days, (p = 0.001). No infection or severe reaction was found in any wounds. This is the first clinical study to show that silk sericin is safe and beneficial for burn wound treatment when it is added to silver sulfadiazine cream.

Abstract
The body's response to tissue injury in a healthy individual is an intricate, sequential physiologic process that results in timely healing with full re-epithelialization, resolution of drainage, and return of function to the affected tissue. Chronic wounds, however, do not follow this sequence of events and can challenge the most experienced clinician if the underlying factors that are impairing wound healing are not identified. The purpose of this article is to present recent information about factors that impair wound healing with the underlying pathophysiological mechanism that interferes with the response to tissue injury. These factors include co-morbidities (diabetes, obesity, protein energy malnutrition), medications (steroids, non-steroidal anti-inflammatory drugs or NSAIDs, anti-rejection medications), oncology interventions (radiation, chemotherapy), and life style habits (smoking, alcohol abuse). Successful treatment of any chronic wound depends upon identification and management of the factors for each individual.

Abstract
Chronic nonsurgical skin wounds such as venous stasis and diabetic ulcers have been associated with a number of comorbid conditions; however, the strength of these associations has not been compared. We utilized the Stanford Translational Research Integrated Database Environment (STRIDE) system to identify a cohort of 637 patients with chronic skin ulcers. Preliminary analysis () showed that 49.7% of the patients had a poor prognosis such as amputation or a nonhealing ulcer for at least a year. Factors significantly associated () with these outcomes included diabetes mellitus, chronic kidney disease, peripheral neuropathy, peripheral arterial disease, and need for systemic antibiotics. Patients with poor outcomes also tended to have lower hemoglobin levels (), higher WBC levels (), and lower albumin levels (). On multivariate analysis, however, only diabetes mellitus (OR 5.87, 1.36–25.3), need for systemic antibiotics (OR 3.88, 1.06–14.2), and albumin levels (0.20 per unit, 0.07–0.60) remained significant independent predictors of poor wound-healing outcomes. These data identify patients at the highest risk for poor wound-healing and who may benefit the most from more aggressive wound care and treatment.

Abstract
BACKGROUND Hypoalbuminemia is associated with increased morbidity in surgical patients. The impact of low albumin level on survival in cardiac surgical patients is unknown. We hypothesized that a low preoperative albumin level negatively affects long-term survival after coronary artery bypass graft (CABG) surgery. METHODS We reviewed prospectively gathered data from the records of 1,164 consecutive patients who underwent primary isolated CABG at our institution between 1997 and 2007. Propensity score analysis of 18 preoperative and intraoperative variables balanced potential confounding factors between the two groups of patients, so that the final study cohort consisted of 588 patients: 294 with a preoperative albumin level less than 3.5 g/dL (ie, hypoalbuminemia) and 294 patients with a preoperative albumin level of 3.5 g/dL or greater. We assessed long-term survival by using Kaplan-Meier curves generated by log rank tests. RESULTS The two groups of patients were well matched in terms of preoperative and intraoperative covariates. Both groups had similar early outcomes, including 30-day mortality rates (2.0% versus 1.7%; p = 0. 76) and the incidence of major adverse cardiac events (2.7% versus 2.7%; p = 1.0). However, patients with hypoalbuminemia had a significantly worse 8-year survival rate (65% ± 7% versus 86% ± 3%; hazard ratio 2.2; 95% confidence interval: 1.4 to 3.6; p = 0.001) than patients without hypoalbuminemia. CONCLUSIONS Although preoperative hypoalbuminemia did not predict increased early postoperative mortality or morbidity in CABG patients, it did independently predict poor long-term survival after CABG. Identifying the mechanism that underlies this relationship is essential in improving overall survival among patients with low serum albumin levels who are undergoing surgical myocardial revascularization.

Abstract
Although our understanding of chronic venous insufficiency (CVI) has improved, many important questions remain unanswered. Ensuring that patients are appropriately referred for specialist assessment and then receive evidence-based, cost-effective treatment continues to be challenging. The lifetime of risk of chronic venous ulceration (CVU) is around 1% with approximately 10% ulcers being open at any one time. The incidence skin changes disease is about 10 times greater (10%). However, many of the studies upon which these estimates are based are old and/or methodologically flawed. There is reason to believe that the incidence, prevalence and characteristics of CVI/CVU may have changed considerably over the last 10-20 years and that future change is likely. Further cross-sectional and longitudinal epidemiological studies are required to establish the size and nature of the health-care need going forward in developed and increasingly developing countries. CVI culminating CVU is primarily the result of sustained ambulatory venous hypertension, which in turn arises from superficial and/or deep venous reflux with or without deep vein obstruction. However, there are many other elements to this complex condition, for example, microvascular dysfunction; calf muscle pump efficiency; dermal inflammation; disordered fibroblast function and matrix production; failure of epithelialization; congenital and acquired thrombophilia; malnutrition, obesity and diet; and bacterial colonization. None of the currently available treatment modalities is entirely satisfactory and novel therapies based upon a clearer understanding of the disease at the psychological, genetic, mechanical, microvascular and microscopic level are required.

Abstract
INTRODUCTION Venous ulcers of lower limbs are often chronic and non-healing, many a time neglected by patients and their treating physicians as these ulcers mostly do not lead to amputation as in gangrenous arterial ulcer and also cost much to complete the course of treatment and prevention of recurrence. MATERIALS AND METHODS One hundred and twenty two lower limb venous ulcers came up for treatment between May 2006 and April 2009. Only twenty nine cases completed the treatment. The main tool of investigation was the non invasive Duplex scan venography. Biopsy of the ulcer was done for staging the disease. Patients' choice of treatment was always conservative and as out-patient instead of hospitalisation and surgery, which required a lot of motivation by the treating unit. RESULTS Out of twenty nine cases, ten cases were treated conservatively and seven (24.13%) healed well. Remaining nineteen cases were given surgical modality in which fifteen cases (51.74%) were successful. Only seven cases (24.13%) failed to heal. Compression stockings were advised to control oedema, varices and pain. Foot care, regular exercises and follow-up were stressed effectively.

Abstract
OBJECTIVE To evaluate whether the topical application of an amino acid dressing, Vulnamin, aids the management of chronic wounds. METHOD A total of 160 patients with non-infected cutaneous chronic wounds were recruited. Before treatment, wound size was assessed using digital planimetry. Treatment lasted for a maximum of six weeks. Wound area measurements were repeated two and six weeks after starting treatment. RESULTS There was a significant reduction in the mean wound area after two weeks (7.4 +/- 8.7cm2) and six weeks (4.6 +/- 6.3cm2) of treatment, when compared with baseline (11.2 +/- 12.1cm2, p<0.01). At the final follow up, 23% of patients (n=36) healed and 34% (n=54) achieved a greater than 60% reduction in wound size. Seventy-six per cent (n=120) achieved positive outcomes (defined as a greater than 40% reduction in the ulcer size). CONCLUSION Although further investigations on the potential effects of this product on chronic wound healing are required, these data suggest it may promote healing in venous, pressure and diabetic ulcers.
