RESUMO

Each year 65% of young athletes and 25% of physically active adults suffer from at least one musculoskeletal injury that prevents them from continuing with physical activity, negatively influencing their physical and mental well-being. The treatment of musculoskeletal injuries with the adhesive elastic kinesiology tape (KT) decreases the recovery time. Patients can thus recommence physical exercise earlier. Here, a novel KT based on auxetic structures is proposed to simplify the application procedure and allow personalization. This novel KT exploits the form-fitting property of auxetics as well as their ability to simultaneously expand in two perpendicular directions when stretched. The auxetic contribution is tuned by optimizing the structure design using analytical equations and experimental measurements. A reentrant honeycomb topology is selected to demonstrate the validity of the proposed approach. Prototypes of auxetic KT to treat general elbow pains and muscle tenseness in the forearm are developed.

RESUMO

It is imperative that the surgical treatment of hip fractures is followed up with rehabilitation to enhance recovery and quality of life. This randomized controlled trial aimed to determine if an individualised, combined exercise-nutrition intervention significantly improved health outcomes in older adults, after proximal femoral fracture. We commenced the community extended therapy while in hospital, within two weeks post-surgery. The primary outcome was gait speed and secondary outcomes included physical function, strength and balance, body composition, energy and protein intake. Eighty-six and 89 participants were randomized into six months individualised exercise and nutrition intervention and attention-control groups, respectively. There were no statistically significant differences in gait speed between the groups at six and 12 months. There were no major differences between groups with respect to the secondary outcomes, except estimated energy and protein intake. This may be explained by the sample size achieved. Participants in the intervention group had greater increment in energy (235 kcal; 95% CI, 95 to 375; p = 0.01) and protein intake (9.1 g; 95% CI, 1.5 to 16.8; p = 0.02), compared with those in the control group at six months but not significant at 12 months. This study has demonstrated that providing early, combined exercise and nutrition therapy can improve dietary energy and protein intake in older adults with hip fractures.

RESUMO

Under stress conditions, the metabolic demand for nutrients increases, which, if not met, may slow down or indeed stop the wound from healing, thus, becoming chronic wounds. This study aims to perform a systematic review and meta-analysis of the effect of arginine and glutamine supplementation on wound healing. PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines were followed for the systematic review and ten electronic databases were used. Five and 39 human studies met the inclusion criteria for arginine and glutamine, respectively. The overall meta-analysis demonstrated a significant effect of arginine supplementation on hydroxyproline content (MD: 4.49, 95% CI: 3.54, 4.45, p < 0.00001). Regarding glutamine supplementation, there was significant effect on nitrogen balance levels (MD: 0.39, 95% CI: 0.21, 0.58, p < 0.0001), IL-6 levels (MD: -5.78, 95% CI: -8.71, -2.86, p = 0.0001), TNFα levels (MD: -8.15, 95% CI: -9.34, -6.96, p < 0.00001), lactulose/mannitol (L/M) ratio (MD: -0.01, 95% CI: -0.02, -0.01, p < 0.00001), patient mortality (OR: 0.48, 95% CI: 0.32, 0.72, p = 0.0004), C-reactive protein (CRP) levels (MD: -1.10, 95% CI: -1.26, -0.93, p < 0.00001) and length of hospital stay (LOS) (MD: -2.65, 95% CI: -3.10, -2.21, p < 0.00001). Regarding T-cell lymphocytes, a slight decrease was observed, although it failed to reach significance (MD: -0.16, 95% CI: -0.33, 0.01, p = 0.07). Conclusion: The wound healing might be enhanced in one or at various stages by nutritional supplementation in the right dose.

RESUMO

Inflammation is an acute adaptive response to injury. However, if the initial inflammatory response to an injury is not completely healed, it becomes chronic low-level inflammation that is strongly associated with many chronic disease states, including metabolic (obesity and diabetes), cardiovascular, auto-immune, and neurogenerative disorders as well as cancer. The healing process is far more complex than the initiation of inflammation. Within that complexity of healing is a sequence of events that are under profound dietary control and can be defined by specific blood markers. Those molecular events of the healing process that are under significant dietary control are termed as the Resolution Response. The purpose of this review is to describe the molecular components of the Resolution Response and how different dietary factors can either optimize or inhibit their actions. In particular, those dietary components that optimize the Resolution Response include a calorie-restricted, protein-adequate, moderate-carbohydrate, low-fat diet referred to as the Zone diet, omega-3 fatty acids, and polyphenols. The appropriate combination of these dietary interventions constitutes the foundation of Pro-Resolution Nutrition. The effect of these dietary components the actions of NF-κB, AMPK, eicosanoids, and resolvins are described in this review, as well as ranges of appropriate blood markers that indicate success in optimizing the Resolution Response by dietary interventions.

RESUMO

BACKGROUND: To investigate the thalamic neurotransmitters and functional connections in the development of chronic constriction injury (CCI)-induced neuropathic pain. METHODS: The paw withdrawal threshold was measured by mechanical stimulation the right hind paw with the von frey hair in the rats of CCI-induced neuropathic pain. The N-acetylaspartate (NAA) and Glutamate (Glu) in thalamus were detected by magnetic resonance spectrum (MRS) process. The thalamic functional connectivity with other brain regions was scanned by functional magnetic resonance image (fMRI). RESULTS: The paw withdrawal threshold of the ipsilateral side showed a noticeable decline during the pathological process. Increased concentrations of Glu and decreased levels of NAA in the thalamus were significantly correlated with mechanical allodynia in the neuropathic pain states. The thalamic regional homogeneity (ReHo) decreased during the process of neuropathic pain. The functional connectivity among the thalamus with the insula and somatosensory cortex were significantly increased at different time points (7, 14, 21 days) after CCI surgery. CONCLUSION: Our study suggests that dynamic changes in thalamic NAA and Glu levels contribute to the thalamic functional connection hyper-excitation during CCI-induced neuropathic pain. Enhanced thalamus-insula functional connection might have a significant effect on the occurrence of neuropathic pain.

RESUMO

Throughout history, various wound healing and management concepts have been recorded, with some approaches such as honey, silver and larvae still in use and others such as blood-letting completely dismissed. In more recent times, dressing products have begun evolving, moving on from basic first-aid supplies to products that support positive healing by addressing the needs of the wound bed and considering underlying factors that impact healing. With an ageing population, the incidence of chronic wounds is predicted to rise, and chronic wounds can negatively impact the lives of patients physically, emotionally and financially. Clinicians continue to explore and review new approaches surrounding the management of wounds, as it is imperative that clinicians use technological advances in wound management alongside established gold standard evidence-based practice to achieve positive outcomes for patients experiencing delayed or challenging wound healing.

RESUMO

Primary care networks (PCNs) were introduced in England in 2019 to bring about closer collaboration between general practice and community health services. The ambition is that greater collaboration between services will achieve better patient outcomes and reduce costs through more effective sharing of staff and resources. Wound care might be considered an ideal focus for PCNs, since general practice and community health services not only have a predominant role in the management of wounds, but variable and suboptimal practice continues and poor outcomes persist. This article investigates some ways in which PCNs might enable health-system changes that could improve the provision of wound care.

RESUMO

BACKGROUND: This study aimed to evaluate the safety and efficacy of 2 forms of vitamin D supplementation on oxidative stress and weaning from the ventilator in patients with traumatic injury and vitamin D deficiency. METHODS: Seventy-two patients were randomly divided into 3 groups: receiving 50,000 IU pearl cholecalciferol daily for 6 days, 1 intramuscular injection of 300,000 IU of cholecalciferol, or a control group that did not receive any supplement. Duration of mechanical ventilation, body composition, and biochemical biomarkers were measured before and after the intervention. RESULT: At the end of the study, the mean serum 25(OH)D increased in the intervention groups compared with the control group (P < .05). The interleukin 6, erythrocyte sedimentation rate, C-reactive protein levels, Sequential Organ Failure Assessment score, duration of mechanical ventilation, and length of intensive care unit admission significantly decreased; however, total antioxidant capacity concentration did not differ significantly between the 2 intervention groups. Among the body composition variables, extracellular water ratio changes were statically different in oral vitamin D group compared with the control group (P = .001). No side effects were reported with the supplements. CONCLUSIONS: Vitamin D administration improved clinical signs and biochemical biomarkers in a small group of patients with traumatic injury. Well-designed multicenter clinical studies with longer intervention duration are necessary for this field.

RESUMO

Reduction of chronic wound pain has the potential to improve patients' quality of life, expedite the healing process and, ultimately, relieve pressure on community services. Despite this, education on pain assessment in the management of chronic wounds is lacking. This literature review seeks to provide evidence-based recommendations to reduce chronic wound pain and inform the practice of community nurses. The results of a thematic analysis indicate that a honey dressing or native collagen matrix dressing and conditioning exercises for the lower leg can reduce pain, and nitroglycerin ointment is especially effective. The review also highlights the need for an individualised approach to the assessment and treatment of pain in patients with chronic wounds.

RESUMO

Anxiety and trauma related disorders are highly prevalent, causing suffering and high costs for society. Current treatment strategies, although effective, only show moderate effect-sizes when compared to adequate control groups demonstrating a need to develop new forms of treatment or optimize existing ones. In order to achieve this, an increased understanding of what mechanisms are involved is needed. An emerging literature indicates that mindfulness training (MFT) can be used to treat fear and anxiety related disorders, but the treatment mechanisms are unclear. One hypothesis, largely based on findings from neuroimaging studies, states that MFT may improve extinction retention, but this has not been demonstrated empirically. To investigate this question healthy subjects either completed a 4-week MFT- intervention delivered through a smart-phone app (n = 14) or were assigned to a waitlist (n = 15). Subsequently, subjects participated in a two-day experimental protocol using pavlovian aversive conditioning, evaluating acquisition and extinction of threat-related responses on day 1, and extinction retention on day 2. Results showed that the MFT group displayed reduced spontaneous recovery of threat related arousal responses, as compared to the waitlist control group, on day 2. MFT did not however, have an effect on either the acquisition or extinction of conditioned responses day 1. This clarifies the positive effect of MFT on emotional functioning and could have implications for the treatment of anxiety and trauma related disorders.

RESUMO

BACKGROUND: Nigella sativa or commonly known as black seed or black cumin is one of the most ubiquitous complementary medicine. Epithelial to mesenchymal transition (EMT) of type 2 is defined by the balance between wound healing and tissue fibrosis, which is dependent to the state of inflammation. This systematic review is conducted to provide an overview regarding the reported effect of Nigella sativa and its bioactive compound on the type 2 EMT. METHODS: A search was done in EBSCOHOST, OVID and SCOPUS database to obtain potentially relevant articles that were published between 1823 and August 2019. This review includes studies that focus on the effect of Nigella sativa and its bioactive compound on the events related to type 2 EMT. RESULTS: A total of 1393 research articles were found to be potentially related to the effect of Nigella sativa and its bioactive compound, thymoquinone on Type 2 EMT. After screening was done, 22 research articles met inclusion criteria and were included in this review. Majority of the studies, reported better wound healing rate or significant prevention of tissue inflammation and organ fibrosis following Nigella sativa or thymoquinone treatments. In terms of wound healing, studies included reported progression of EMT related pathological changes after treatment with Nigella sativa or thymoquinone. Alternatively, in terms of fibrosis and inflammation, studies included reported reversal of pathological changes related to EMT after treatment with Nigella sativa or thymoquinone. CONCLUSION: Through this review, Nigella sativa and thymoquinone have been associated with events in Type 2 EMT. They have been shown to promote wound healing, attenuate tissue inflammation, and prevent organ fibrosis via regulation of the EMT process.

RESUMO

A polyphenolic-rich fraction (CG50) was obtained from the methanol extract of Coccinia grandis leaves by chromatographic fractionation over a Diaion column using 50% aqueous methanol. LC-ESI-MS/MS analysis of CG50 showed the presence of six flavonoids, namely quercetin-hexoside deoxyhexoside (rutin), quercetin-hexoside deoxyhexoside (quercetin-3-O-neohesperidoside), kaempferol-hexoside deoxyhexoside (kaempferol-3-O-rutinoside), kaempferol-hexoside deoxyhexoside (kaempferol-3-O-neohesperidoside), kaempferol-3-O-glucoside, and kaempferol-hexoside in addition to the presence of two secoiridoids which are oleuropein and ligstroside. CG50 hydrogel showed a pronounced inhibition of the bacterial growth in wounds infected by Bacillus cereus in rats comparable to those treated with hydrogel base only showing 85.08 and 16.50% inhibition for the bacterial growth for the CG50 hydrogel and hydrogel base, respectively. The antimicrobial activity of CG50 hydrogel was close to that of fucidin during all days of treatment. Rats treated with CG50 hydrogel showed remarkable healing ability of the wound compared to other groups and approaching that of fucidin. This was clearly manifested by the clear formation of scars with obvious reduction in the wound size together with the appearance and re-growth of hair. This was further confirmed by the histopathological study of skin tissues as well as by the evaluation of the percentages of collagen fiber deposition. CG50 hydrogel showed 18.71% collagen fiber deposition comparable to the untreated group that showed 6.84% collagen fiber deposition and approaches that of the fucidin group. It was concluded that Coccinia grandis could be used as a natural wound healing agent that further consolidated its traditional use as a wound dressing.

RESUMO

BACKGROUND: Fumaria species (Fumariacea) has traditionally been used in wound healing in Iranian folk medicine. However, with the discovery of newer agents, its use has faded off into total obscurity. This study explored the wound healing potential of a gel containing 10% Fumaria vaillantii Loisel through topical application of total extract in a model of excisional as well as incisional wound healing in albino Wistar rats. METHODS: Rats were anesthetized, and excisional skin wound was established using a sterilized surgical scissors. The animals were then treated with 10% F.vaillantii topical gel formulation along with the gel base. The treatments were administered once a day after the injury for 21 days. For topical treatment, the hydrogel was formulated and evaluated for chemical and physical characteristics. Histopathological analysis with hematoxylin and eosin (H&E) was used for microscopic examination of the skin tissues on 21-day-old sections of excision wound. To verify collagen formation, hydroxyproline determination was performed 21 days post wound healing. Breaking strength was determined in a 10-day-old incision wound by the uniaxial tensile test. RESULTS: Topical administration of F.vaillantii gel formulation significantly enhanced skin wound closure on the 6th post-wounding day compared to both gel base and the negative control, indicating an accelerated wound healing process, while a significant difference was observed on 10th and 14th post -wound days in F.vaillantii treatment compared to the negative control groups. Gel formulation prepared with a 10% F. vaillantii extract exhibited a response in terms of wound epithelialization, angiogenesis and number of hair follicles at wound area better than the gel base on the 21st post-wound day. Application of gel base produced further advantages by increasing hydroxyproline content and collagen fiber thickness. Our results on incision wound model were supported by histopathological data indicating the role of gel base in the enhancement of breaking strength. CONCLUSION: Traditional use of Fumaria species in the skin diseases was justified in this study by revealing the increase in wound healing activity after hydrogel containing F. vaillantii total extract administration.

RESUMO

BACKGROUND: Various extracts of Centella asiatica (Apiaceae) and its active constituent, asiaticoside, have been reported to possess wound healing property when assessed using various in vivo and in vitro models. In an attempt to develop a formulation with accelerated wound healing effect, the present study was performed to examine in vivo efficacy of asiaticoside-rich hydrogel formulation in rabbits. METHODS: Asiaticoside-rich fraction was prepared from C. asiatica aerial part and then incorporated into polyvinyl alcohol/polyethylene glycol (PVA/PEG) hydrogel. The hydrogel was subjected to wound healing investigation using the in vivo incision model. RESULTS: The results obtained demonstrated that: i) the hydrogel formulation did not cause any signs of irritation on the rabbits' skin and; ii) enhanced wound healing 15% faster than the commercial cream and > 40% faster than the untreated wounds. The skin healing process was seen in all wounds marked by formation of a thick epithelial layer, keratin, and moderate formation of granulation tissues, fibroblasts and collagen with no fibrinoid necrosis detected. CONCLUSION: The asiaticoside-rich hydrogel developed using the freeze-thaw method was effective in accelerating wound healing in rabbits.

RESUMO

Wound healing involves the interaction of blood cells, proteins, proteases, growth factors, and extracellular matrix components. Inflammation is one of the first events occurring during this process. Previously, we showed that the N-Methyl-(2S,4R)-trans-4-Hydroxy-L-Proline (NMP) from Sideroxylon obtusifolium leaves (a Brazilian medicinal species) presents an anti-inflammatory action. Considering inflammation as an important event in the wound healing process, the objectives were to investigate the topical effects of the NMP gel on a mice wound-induced model. Male Swiss mice were divided into 4 groups: Sham (surgical procedure only), Control (gel-base treated), and 3% or 10% NMP gel-treated groups. Measurements of wound areas and microscopic analyses (HE [hematoxylin-eosin] and PSR [picrosirius red] stainings) were carried out, at the 7th and 12th, days after the wound induction. Furthermore, immunohistochemical assays for iNOS (inducible nitric oxide synthase) and COX-2 (cyclooxygenase-2) and biochemical measurements for TBARS (thiobarbituric acid reactive substances), GSH (glutathione), and myeloperoxidase (MPO) were also performed, at the second day after the wound induction. The work showed that NMP decreases the wound areas, after topical application, relatively to the Sham and Control groups. In addition, microscopic alterations were reduced and collagen deposition was increased, at the 7th and 12th days, in the 10% NMP group. While iNOS and COX-2 immunostainings and GSH contents increased, in relation to the Sham and Control groups, TBARS and MPO decreased. Altogether, the results showed NMP to improve the wound healing process, by upregulating iNOS and COX-2 activities, reducing lipid peroxidation and MPO activity, and increasing GSH contents. In addition, NMP certainly contributes to the increased collagen deposition. These data may stimulate translational studies dealing with the possible use of NMP from Sideroxylon obtusifolium or from other sources for the management of wound healing.

The effects of aqueous-ethanol extract of Horse chestnut (HCE) on MMP-1 and MMP-9 expressions during cutaneous wound healing in diabetic rats were investigated in this study. The expressions of MMP-1 and MMP-9, wound closure, myeloperoxidase (MPO) activity, hydroxyproline, and malondialdehyde (MDA) levels in wound tissue were measured. Quercetin glucuronide in HCE was identified as main compound using a LC-MS/MS. The hydroxyproline level was significantly increased in the treated group versus control after the 3rd and 7th days (p < 0.05). The MDA level and MPO activity were significantly lower in the treatment group (p < 0.05). MMP-1 gene expression level in treated rats was increased in the 7th day while it was reduced in 14th day. MMP-9 gene expression level in treated rats was decreased in 7th, and 14th days compared to control (p < 0.05). These results show that HCE accelerated the cutaneous wound-healing process in diabetic rats via MMP-1 and MMP-9 regulation. PRACTICAL APPLICATIONS: The main function of MMPs is to degrade and deposite the various components of the extracellular matrix. Also, they participate physiological processes such as inflammation, angiogenesis, and tissue remodeling. Horse chestnut seeds (HC) are known to be rich in saponins and flavonoids. HC are used for the treatment of abdominal pain, stomach ache, cold, hemorrhoids, arterial stiffness, rheumatism, oedema, diarrhea, chronic venous insufficiency and also as an antihemorrhagic and antipyretic in traditional medicine. It has been shown that HC has anti-inflammatory, antioedema, vessel protective, and free radical scavenging properties. This study indicates that HCE could be an effective agent for wound healing in diabetic wound model via its ability to suppress the MMP-9 gene expression and regulates MMP-1 gene expression besides its antioxidative, anti-inflammatory effects.

RESUMO

Skin insult and damage start a complex healing process that involves a myriad of coordinated reactions at both the cellular and molecular level occurring simultaneously. These processes can be divided into that of cell migration and tissue remodeling of the wound. In addition, it is well known that deep wounds that derive from surgical procedures need a multidisciplinary approach to have a successful wound healing process. Recently, there has been a renowned interest in the identification of active compounds derived from ornamental, edible, and wild plants being used in the cosmetic and skin product industry. Recent reports suggest that active components of several plants such as Propolis and Aloe vera could be used to induce the process of wound healing and tissue regeneration and reducing therefore the time to complete wound closure. Other plant species such as Achillea millefolium or Salvia officinalis have anti-inflammatory properties and promote cellular proliferation contributing to faster tissue regeneration. It has been described that Malva sylvestris influences the formation of fibrosis-free granulation tissue in the skin. Recent observations suggest that Casearia sylvestris induces the angiogenic process. These effects have been evaluated in cell lines, different animal models, and some in randomized clinical trials. In this review we summarize the evidence of plant extracts and their active components (when known) in the acceleration of the wound closure process and tissue repair.

RESUMO

Background Traumatic comatose patients may experience disturbances in hemodynamic indices due to the nature of their disorder. This study aimed to compare the effects of nature sounds and reflexology on hemodynamic indices in traumatic comatose patients. Methods This randomized clinical trial using a factorial design was conducted on 120 traumatic comatose patients in two teaching hospitals in two urban areas of Iran. The patients were selected using a sequential sampling method and assigned into randomized quadruple blocks as control, nature sounds, reflexology and nature sounds-reflexology (combined) groups. The interventions were performed twice daily in two consecutive days lasting 30 min each time. The hemodynamic indices were measured before, and immediately, 30 min, and 2 h after the intervention using calibrated monitors. Descriptive and inferential statistics, including one-way ANOVA, Scheffe ad hoc, repeated measure ANOVA, Bonferroni ad hoc Chi-square test and Fisher's exact tests were used for data analysis via the SPSS software V.16. Results Significant differences were reported in terms of the mean arterial pressure between the control and reflexology groups (p=0.002), and the combined group (p=0.008) immediately after the interventions. The combined group showed statistically differences in systolic blood pressure compared to the nature sounds (p=0.007) and control (p=0.015) groups 30 min after the interventions. The nature sounds group showed differences in the pulse rate from the reflexology (p=0.048) and control (p=0.015) groups 30 min after the interventions in the second day. Conclusions While the immediate effects of the interventions on induction of the feeling of relaxation and tranquility, and reduction of hemodynamic indices were reported, they diminished over time. Nature sounds and reflexology as low-cost and relaxing tranquilizing methods can be used for the reduction of tension and improvement of hemodynamic indices among traumatic comatose patients.

RESUMO

In recent years, wound repair, especially chronic and refractory wounds, is still a growing worldwide health problem that concerns the physical and mental health of patients and the productivity of society as a whole. In many developed countries and developing countries, such as China, rapid economic growth, negative lifestyle changes (such as increased dietary fat intake and reduced physical activity), and increasingly serious aging problems have led to more and more refractory wounds caused by chronic diseases, such as diabetes and microvascular diseases. There is a clear and orderly stage in the process of wound healing, and the malfunction of any step will lead to poor healing effect. There are many causes of refractory wounds, among which the poor vascular network is closely related. This review focuses on the role and improvement of the microvasculature in wound repair. In addition, the future developmental trend of wound regenerative therapy (active factors, [stem] cells, tissue-induced biomaterials, gene therapy, etc) is also considered.
