Recursos documentales CUIDEN y su utilidad para la evaluación del conocimiento en Cuidados de Salud

La inclusión de revistas científicas en fuentes documentales ha evolucionado desde la exhaustividad hacia la selectividad, en función del uso creciente que se hace de las mismas a efectos de evaluación del conocimiento. El entorno CUIDEN, que incorpora la base de datos referencial y el índice de citas CUIDEN Citación, no ha sido ajeno a esta tendencia, de manera que en los últimos años ha extremado los criterios de selección, a la vez que ha reducido el tiempo en que la información bibliométrica está disponible. En este trabajo se describen ambos recursos documentales y se exponen sus propiedades en la evaluación de revistas de enfermería y afines del ámbito iberoamericano, complementando así la escasa información que sobre las mismas proporcionan otras fuentes más genéricas. Se aporta como ejemplo dos modelos de evaluación correspondientes a los países más productores de conocimiento enfermero en Iberoamérica: Brasil y España.

Does obesity impact the outcome of severely burned patients?

Abstract

Although obesity appears to be an important predictor of mortality and morbidity, little data about the impact of body mass index (BMI) on the outcome of severely burned patients are available. Patients admitted to the General Hospital Vienna between 1994 and 2014, who underwent surgery because of burn injuries, were enrolled in this study. BMI was used to divide patients into five groups: BMI 18.5 to 24.9, 25 to 29.9, 30 to 34.9, 35 to 39.9, and > 40. The groups were compared in terms of difference of mortality and morbidity. Of 460 patients, 34.3% (n = 158) died. Mortality rates were the lowest in patients with obesity class III and the highest in patients with BMI 35 to 39.9 (BMI 18.5‐24.9: 30.5%, BMI 25‐29.9: 31.5%, BMI 30‐34.9: 41.3%, BMI 35‐39.9: 55.5%, BMI > 40: 30%; P = .031). BMI was not found to be an independent risk factor when corrected with age, percent total body surface area burned, full‐thickness burns, and inhalation injury. No significant differences in length of stay, inhalation trauma, pneumonia, wound infection, sepsis, and invasive ventilation were observed. BMI as an independent risk factor for severely burned patients could not be confirmed via multivariate analysis.

Knowledge Discovery With Machine Learning for Hospital-Acquired Catheter-Associated Urinary Tract Infections

imageMassive generation of health-related data has been key in enabling the big data science initiative to gain new insights in healthcare. Nursing can benefit from this era of big data science, as there is a growing need for new discoveries from large quantities of nursing data to provide evidence-based care. However, there are few nursing studies using big data analytics. The purpose of this article is to explain a knowledge discovery and data mining approach that was employed to discover knowledge about hospital-acquired catheter-associated urinary tract infections from multiple data sources, including electronic health records and nurse staffing data. Three different machine learning techniques are described: decision trees, logistic regression, and support vector machines. The decision tree model created rules to interpret relationships among associated factors of hospital-acquired catheter-associated urinary tract infections. The logistic regression model showed what factors were related to a higher risk of hospital-acquired catheter-associated urinary tract infections. The support vector machines model was included to compare performance with the other two interpretable models. This article introduces the examples of cutting-edge machine learning approaches that will advance secondary use of electronic health records and integration of multiple data sources as well as provide evidence necessary to guide nursing professionals in practice.

Non‐healing wounds: Can it take different diagnosis?

Abstract

Wound healing is a complex cellular and biochemical process and can be affected by several systemic and local factors. In this study, we aimed to discuss the aetiologic factors of non‐healing wounds and the management of this complicated process with current information. The medical data of the patients who were admitted to our clinic due to non‐healing or chronic wounds were analysed retrospectively. A total of 27 patients were evaluated retrospectively during the 14 months of the study. The data of 6 patients who were followed up for chronic wound that developed after abdominal incisional hernia repair and pilonidal sinus surgery were not included in the study as their data could not be reached. A total of 21 patients were included in the study. Malignancy was diagnosed in two patients and granulomatous disease was found in four patients. The aetiology of the other cases included foreign body reaction, infection, and mechanical causes. Non‐healing wounds are a serious social and economic problem for patients. Further studies on the pathophysiology of various aetiologies in non‐healing wounds in both clinical settings and experimental animal models would be a useful step in treatment.

Coverage of exposed bone and hardware of the medial malleolus with tibialis posterior artery perforator flap after ankle fracture surgery complications

Abstract

Ankle fractures are among the most common orthopaedic surgical procedures. Skin‐related complications of these surgeries are difficult to reconstruct due to the inadequacy of soft tissue in the region. Although free flaps are generally considered as the first choice in reconstruction of this area, free flaps may not be a suitable option especially in patients with advanced age and comorbidities. Perforator flaps offer a fast and safe alternative in lower extremity reconstruction. In the literature, there are a limited number of studies using perforator flaps in managing the postoperative complications of the lower extremity trauma surgeries. In our study, we report our experience with reconstruction of soft‐tissue defects of medial malleolar region using posterior tibial artery perforator flap for postoperative complications of ankle fracture‐related surgeries.

Biological approaches for hypertrophic scars

Abstract

Scar formation is usually the pathological consequence of skin trauma. And hypertrophic scars (HSs) frequently occur in people after being injured deeply. HSs are unusually considered as the result of tissue contraction and excessive extracellular matrix component deposition. Myofibroblasts, as the effector cells, mainly differentiated from fibroblasts, play the crucial role in the pathophysiology of HSs. A number of growth factors, inflammatory cytokines involved in the process of HS occurrence. Currently, with in‐depth exploration and clinical research of HSs, various creative and effective treatments budded. In here, we summarize the progress in the molecular mechanism of HSs, and review the available biotherapeutic methods for their pathophysiological characteristics. Additionally, we further prospected that the comprehensive therapy may be more suitable for HS treatment.

Asociación de las conductas de riesgo en adolescentes. Estrategias para su prevención

Objetivo principal: Analizar la  asociación de conductas de riesgo para la salud en el marco de la Teoría de la Conducta Problema. Metodología: 524 adolescentes (Medad =16,7; DT = 1,6) cumplimentaron un cuestionario online. Mediante Análisis Factorial Exploratorio se estudiaron seis conductas: borracheras, consumos de tabaco y  hachís,  búsqueda de sensaciones, sexo sin protección y comportamiento vial inseguro. Resultados principales: En la adolescencia intermedia (edades 16-17) la agrupación resultó compatible con la dimensión “no convencionalidad” identificada por Jessor. Su prevalencia aumentó al finalizar la educación obligatoria. Conclusión: Esta agrupación aconseja la prevención simultánea de dichas conductas. Dado que estos comportamientos ayudan a los adolescentes a ganar autonomía personal y relacionarse con sus iguales, su prevención no debe limitarse a informar sobre los  riesgos que ocasionan. Promover conductas prosociales (p.ej., participar en la vida escolar y comunitaria) puede ayudar a los adolescentes a vivir de manera saludable su transición evolutiva.

A randomised clinical trial to compare octyl cyanoacrylate with absorbable monofilament sutures for the closure of laparoscopic cholecystectomy port incisions

Abstract

Tissue adhesives have gained increasing use as a possible method of wound closure. We compared the use of 2‐octyl cyanoacrylate (OCA) or subcuticular suture in incisions sutures for the closure of laparoscopic cholecystectomy port incisions. A prospective randomised controlled trial was performed. Patients were randomised to have closure of laparoscopic port sites using either OCA or sutures. Patients were reviewed at 24 hours and returned for follow‐up 1 week and 1 month after postoperatively. At these times, different wound characteristics were documented: Two tools were used to measure the cosmetic result using Hollander wound evaluation scale (HWES) and the patient and observer scar assessment scale (POSAS). A total of 70 patients, 35 in each group were enrolled. The wounds were closed significantly faster in the OCA group (mean 229.16 [±43.7] seconds versus 258.82 [±51.7] seconds, P = .01). Statistically significant difference in favour of using OCA was found for dehiscence (17.1% versus none in the suture group, P = .025) after 1 week. However, no difference was found for wound dehiscence after 1 month. OCA and suture groups did not differ significantly on patient satisfaction. There were no differences in the percentage of wounds achieving optimal scores on the HWES (suture 85.7% versus OCA 74.2%, P = .169). Nerveless, wound evolution was judged to be significantly better in the OCA group using POSAS. Patients' median POSAS was 9.45 (6–11) and 11.43 (10–13) in the OCA and suture groups, respectively (P = .005), and surgeon's median POSAS was 9.42 (6–11) and 11.48 (10–13) in the OCA and suture groups, respectively (P = .006). N‐butyl‐cyanoacrylate tissue adhesive is an acceptable technique for the closure of laparoscopic wounds with less operative time, and cosmetic results are comparable to suturing.

Instillation negative pressure wound therapy: An effective approach for hardware salvage

Abstract

Wound infection involving hardware can be notoriously difficult to treat, often requiring the removal of the infected implant. The goal of this study was to determine the utility of instillation negative pressure wound therapy to help eradicate infection and allow for definitive wound closure in patients without removing the infected hardware. A retrospective review was performed on the outcomes of 28 patients who presented with open wounds with exposed or infected hardware and who were treated with a combination of surgical debridement and negative pressure wound therapy with instillation (NPWTi). Eleven patients were treated for infected spinal hardware, 12 for extremity, and 5 for sternal hardware. Twenty‐five of 28 (89%) patients had successful retention or replacement of hardware, with clearance of infection and healed wounds. Original hardware was maintained in 17 of 28 (61%) patients. In 11 patients, original hardware was removed, with subsequent replacement in eight of those patients after a clean wound was achieved. Average time to definitive closure was 12.6 days. Average follow‐up was 135 days. This series supports NPWTi as an effective adjunct therapy to help expeditiously eradicate hardware infection, allowing for hardware retention.

Effects of photoelectric therapy on proliferation and apoptosis of scar cells by regulating the expression of microRNA‐206 and its related mechanisms

Abstract

Human skin fibroblast (HSF) cells were irradiated with different energy lasers to detect cell proliferation, apoptosis, and expression of microRNA‐206 and protein, and to further summarise the therapeutic effect of laser on scar cells. Human scar cell line HSF cells were cultured in three groups. The control group was not irradiated by laser, the low‐energy group was irradiated by 10 J/cm2 laser, and the high‐energy group was irradiated by 20 J/cm2 laser. After irradiation, HSF cells were cultured for 20 hours. Cell proliferation was detected by MTT assay. Cell cycle and apoptosis were detected by flow cytometry. Transwell migration assay was used to detect cell migratory ability. Reverse transcription polymerase chain reaction (RT‐PCR) was used to detect miR‐206 and mTOR gene levels. The levels of MMP‐9, Bax, Bcl‐2, cyclin D1, and mTOR signalling pathway proteins were detected by Western blotting assays. The results showed that after laser irradiation, the proliferation of cells decreased, and the difference between the control group and the experimental group was significant (P < .05). The higher the energy was, the greater the upregulation of apoptosis was. Apoptosis and cell migration increased (P < .05). The expressions of microRNA‐206, MMP‐9, and Bax were upregulated, while the expressions of mTOR, Bcl‐2, and cyclin D1 were downregulated. To sum up, laser irradiation can significantly inhibit the proliferation of HSF cells, affect cell cycle, and increase cell apoptosis and migratory ability.

The effects of intravenous lidocaine on wound pain and gastrointestinal function recovery after laparoscopic colorectal surgery

Abstract

To evaluate the efficacy of intravenous lidocaine in relieving postoperative pain and promoting rehabilitation in laparoscopic colorectal surgery, we conducted this meta‐analysis. The systematic search strategy was performed on PubMed, EMBASE, Chinese databases, and Cochrane Library before September 2019. As a result, 10 randomised clinical trials were included in this meta‐analysis (n = 527 patients). Intravenous lidocaine significantly reduced pain scores at 2, 4, 12, 24, and 48 hours on movement and 2, 4, and 12 hours on resting‐state and reduced opioid requirement in first 24 hours postoperatively (weighted mean difference [WMD] = −5.02 [−9.34, −0.70]; P = .02). It also decreased the first flatus time (WMD: −10.15 [−11.20, −9.10]; P < .00001), first defecation time (WMD: −10.27 [−17.62, −2.92]; P = .006), length of hospital stay (WMD: −1.05 [−1.89, −0.21]; P = .01), and reduced the incidence of postoperative nausea and vomiting (risk ratio: 0.53 [0.30, 0.93]; P = .03) when compared with control group. However, it had no effect on pain scores at 24 and 48 hours at rest, the normal dietary time, and the level of serum C‐reactive protein. In summary, perioperative intravenous lidocaine could alleviate acute pain, reduce postoperative analgesic requirements, and accelerate recovery of gastrointestinal function in patients undergoing laparoscopic colorectal surgery.

Health checks have a limited effect on reducing morbidity and mortality in asymptomatic populations

Por: Frazer · K.

Commentary on: Krogsbøll LT, Jørgensen KJ, Gøtzsche PC. General health checks in adults for reducing morbidity and mortality from disease. Cochrane Database Syst Rev 2019;1:CD009009. DOI: 10.1002/14651858.CD009009.pub3.

Implications for practice and research

  • Current evidence does not support continuing trials of health checks in general population and could lead to unnecessary tests and treatments.

  • Future research should examine effects of structural public health interventions including effects of higher tax on cigarettes and alcohol on reducing disease.

  • Context

    General health check programmes screen asymptomatic groups with the aim of detecting disease or risk factors at an earlier stage to prevent future illness and improve health outcomes.1 2 General health screening, while providing benefits, is associated with disadvantages including false reassurance or over treatment.3 Criteria for establishing screening and evaluation of programmes are essential.3

    Development and psychometric evaluation of the patient knowledge of, and attitudes and behaviours towards pressure ulcer prevention instrument (KPUP)

    Abstract

    The Patient Knowledge of, and Attitude and Behaviour towards Pressure Ulcer Prevention Instrument (KPUP) was developed and validated using a two‐stage prospective psychometric instrument validation study design. In Stage 1, the instrument was designed, and it is psychometrically evaluated in Stage 2. To establish content validity, two expert panels independently reviewed each item for appropriateness and relevance. Psychometric evaluation included construct validity and stability testing of the instrument. The questionnaire was administered to a convenience sample of 200 people aged more than 65 years, living independently in the community; reliability and stability were assessed by test/retest procedures, with a 1‐week interval. Mean knowledge scores at ‘test’ were 11.54/20 (95% CI = 11.10‐11.99, SD: 3.07), and ‘retest’ was 12.24 (95% CI = 11.81‐12.66, SD: 2.93). For knowledge, correlation between the test/retest score was positive (r=. 60), attitude section‐inter‐item correlations ranged from r = −.31 to r = .57 (mean intraclass correlation coefficient of r = .42), and internal consistency for the retest was the same as the test (α = .41 for the eight items). For health behaviours, individual inter‐item correlations for test items ranged from r = −.21 to r = .41 for the 13 standardised items. Psychometric testing of the KPUP in a sample of older persons in the community provided moderate internal consistency and general high test‐retest stability.

    Vacuum‐assisted closure therapy combined with bi‐pectoral muscle flap for the treatment of deep sternal wound infections

    Abstract

    Deep sternal wound infection (DSWI) is a fatal complication after median sternotomy. This study was to assess the effect of vacuum‐assisted closure (VAC) combined with bi‐pectoral muscle advancement flap therapy on rehabilitation for the treatment of DSWI. Fifty‐two patients with DSWI underwent treatment of VAC and bi‐pectoral muscle flap. These patients were followed‐up 12 months postoperation. The patient characteristics, duration of VAC therapy, the mean hospital stay, and postoperative complications were retrospectively analysed. All patients underwent 1 to 3 VAC treatment sessions before closure. Fifty‐one of 52 DSWI patients were cured to discharge; the mean hospital stay was 26.5 days. The drainage tube continued to drain a large amount of bloody fluid in three patients after the wound was closed. Respiratory failure occurred in one patient with severe mediastinal and pulmonary infections and died eventually in hospital. One patient died of acute cerebral haemorrhage during the12‐month follow‐up. VAC therapy combined with bi‐pectoral muscle flap is a simple and effective treatment for DSWIs with short hospital stays and few complications. However, this is a retrospective case series presentation with no comparison group; further large‐scale controlled studies are needed.

    Selective debridement of burn wounds using hydrosurgery system

    Abstract

    In recent years, hydrosurgery is a technology that has been applied more and more in debridement procedures. However, the selectivity of hydrosurgery to cutaneous necrotic tissues has not been proved. This study was designed to investigate the possible tissue selectivity of hydrosurgery in the debridement in burn wounds. Deep partial‐thickness burns were produced on the back of porcine, and 48 hours later, both burn wounds and normal skin were debrided using the hydrosurgery system. Then tissue samples were taken, and histological staining was performed and observed under microscope. Burn wound resection rates and the normal skin damaged rates were measured. Our result indicated that the burn wounds were significantly more sensitive than the normal skin when the water pressure produced by the hydrosurgery system was set between 3000 and 5000 psi (pounds per square inch), that is, the necrotic tissue portions were debrided more easily than the normal skin tissue. Based on these data, we suggest that 3000 to 5000 psi of water pressure in the hydrosurgery system has a skin tissue selectivity in burn wounds.
