Effects of antimicrobials over sessile and planktonic microbiota associated with an industrial cooling water system.

The bacterial community from a cooling water system was investigated through culture-dependent and independent strategies, and the responses of planktonic and sessile bacteria (grown in glass slides and stainless-steel coupons) to antimicrobials of industrial and clinical use were assessed. The morphotypes with higher biofilm-forming potential were Pseudoxanthomonas sp., Rheinheimera sp., Aeromonas sp. and Staphylococcus sp., and the first also exhibited lower susceptibility to all antibiotics and biocides tested. 16S rRNA high throughput sequencing indicated that Pseudomonadota (77.1% on average, sd 11.1%), Bacteroidota (8.4, sd 5.7%), and Planctomycetota (3.0, sd 1.3%) were the most abundant phyla. KEGG orthologs associated with antibiotics and biocide resistance were abundant in all samples. Although the minimum inhibitory and bactericidal concentrations were generally higher for biofilms, morphotypes in planktonic form also showed high levels of resistance, which could be associated with biofilm cells passing into the planktonic phase. Overall, monochloramine was the most effective biocide.

Cultural adaptation and validation of the Ghent global IAD monitoring tool (GLOBIAD-M) for Brazilian Portuguese.

BACKGROUND: Incontinence-associated dermatitis (IAD) poses a significant challenge for individuals experiencing incontinence, characterized by irritative contact dermatitis due to prolonged exposure to urine and/or faeces. OBJECTIVE: This study aimed to culturally adapt the Ghent Global IAD Monitoring Tool - GLOBIAD-M to Brazilian Portuguese and to assess the adapted version's measurement properties quality. METHOD: A clinimetric study was conducted, comprising cultural adaptation and psychometric assessment. Cultural adaptation followed international guidelines, while psychometric properties were evaluated for content validity, inter-rater reliability, and correlation with other variables (thermography). Inter-rater reliability was assessed through clinical and photographic evaluations. The study samples included linguists and, IAD specialists, nurses, and adult patients with IAD according to the cultural adaptation or psychometric evidence assessment. RESULT: The process of cultural adaptation resulted in a cumulative coefficient of variation ratio (CVR) of 0.66. Subsequently, the study included 57 patients and 57 nurses for clinical assessments, totalling 166 evaluations of IAD. The inter-rater reliability among nurses was deemed satisfactory, with a Gwet coefficient of 0.77. Moreover, out of 215 photographic assessments conducted by 54 nurses, there was a 92.1 % concurrence in the categorization of IAD. Furthermore, thermography analysis revealed significant temperature differences between healthy individuals and those with IAD, particularly in patients categorized under IAD Cat. 1B, showing a difference of 1.90 °C. CONCLUSION: and Impact on Clinical Practice: The results confirm the availability of the GLOBIAD-M in its Brazilian Portuguese version. This tool will allow health professionals to obtain a standardized IAD classification and monitoring in Brazil, enhancing its diagnostic accuracy and aiding clinical decision-making.

Exploring the effect of wound related pain on psychological stress, inflammatory response, and wound healing.

AIMS AND OBJECTIVES: The relationship between pain and poor healing is intricate, potentially mediated by psychological stress and aberrations in inflammatory response. The purpose of this study was to examine the biopsychosocial model of pain by assessing the relationships between pain, stress, inflammation and healing in people with chronic wounds. DESIGN: This was a 4-week prospective observational study to explore the relationship of pain, stress, inflammation and wound healing in a convenience sample of patients with chronic wounds in a chronic care hospital in Canada. METHODS: Only subjects over 18 with chronic wounds were recruited into the study. Chronic wounds were defined by the duration of wounds for more than 4 weeks of various aetiologies including wounds caused by pressure injuries, venous disease, arterial insufficiency, surgery or trauma and diabetic neuropathy. Participants were evaluated for pain by responding to the Brief Pain Inventory-Short Form, the McGill Pain Questionnaire-Short Form and the Leeds Assessment of Neuropathic Symptoms and Signs scale. Stress was measured by the Perceived Stress Scale (PSS). All wounds were assessed with the Pressure Ulcer Scale for Healing tool. The levels of matrix metalloproteinases were analysis by obtaining wound fluid from all participants. RESULTS: A total of 32 individuals with chronic wounds participated in the study. Correlation analysis indicated pain severity was positively and significantly related to pain interference, McGill Pain Questionnaire scores, neuropathic pain and matrix metalloproteinase levels. Logistic regression was used to determine the predictors for high or low perceived stress. The only significant variable that contributed to the stress levels was BPI-I. Results suggested that participants who experienced higher levels of pain interference also had an increased odds to report high level of stress by 1.6 times controlling for all other factor in the model. CONCLUSION: Pain is a complex biopsychosocial phenomenon affecting quality of life in people with chronic wounds. Results of this study identified a significant relationship between pain, stress and wound healing.

Topical therapy for pain management in malignant fungating wounds: A scoping review.

AIMS AND OBJECTIVES: To map and synthesise the existing literature on topical therapies for malignant fungating wounds pain management and the gaps involved. BACKGROUND: Most cancer patients with malignant fungating wounds suffer from wound-related pain, affecting their quality of life. Unfortunately, even though pain is a relevant symptom in cancer and palliative care, little is currently known about topical treatments' availability and impact on pain management. DESIGN: A scoping review following JBI® methodology METHODS: Searches were performed in CINAHL, LILACS, Embase, Web of Science, PubMed, Cochrane, NICE, Scopus, JBISRIR and grey literature, in English, Portuguese and Spanish, with no time limit. Two authors independently reviewed all citations and a third was called in case of divergence, and studies in adults with malignant fungal wounds reporting topical pain interventions were included. In addition, a data extraction tool for synthesis and thematic analysis was developed. This study followed the PRISMA-ScR Checklist. RESULTS: Seventy publications were selected from 796 records retrieved from databases. The studies mainly included non-systematic reviews and case studies with only six clinical trials. According to the narrative synthesis, twenty therapies were identified, including the use of wound dressings (58.6%), analgesic drugs (55.7%), topical antimicrobials (25.7%), skin barriers (15.7%), cryotherapy (5.7%) and negative pressure wound therapy (4.3%). Therapies were recommended to be applied to the wound bed or the periwound skin. In 68.5% of the studies, a standardised assessment for pain was not described. CONCLUSIONS: Topical therapies applied to malignant fungating wounds or periwound areas had been examined for pain management. However, their effectiveness was analysed in a few interventional studies, indicating the need for further primary studies to inform evidence-based practice. IMPLICATION FOR PRACTICE: Highlighted topical therapies for clinical practice consideration are opioids, anaesthetics and antimicrobials, with positive results described in randomised clinical trials. This study did not include patients.

Cultural Adaptation and Validation of the Ostomy Skin Tool to the Brazilian Portuguese.

PURPOSE: To adapt the Ostomy Skin Tool (discoloration, erosion, and tissue overgrowth) to the Brazilian culture and to analyze psychometric properties of the adapted version. DESIGN: Psychometric (methodologic) evaluation of the instrument. SUBJECTS AND SETTING: Three ostomy/enterostomal therapy nurses evaluated the extent and severity of peristomal skin conditions in a sample of 109 adults 18 years or older with peristomal skin complications. These participants were receiving care in an ambulatory care center in outpatient health services in Sao Paulo and Curitiba, Brazil. In addition, interobserver reliability was measured using a group of 129 nurse participants who attended the Brazilian Congress of Stomatherapy held from November 12 to 15, 2017, in Belo Horizonte, a city located in the state of Minas Gerais, Brazil. Nurse participants assessed the descriptions of peristomal skin complications of the Portuguese version, using the same photographs used in the original DET score, purposely placed out of original order. METHODS: The study was performed in 2 stages. The instrument was translated into Brazilian Portuguese by 2 bilingual translators, and back-translated into English. The back-translated version was sent to one of the developers of the instrument for additional evaluation. During stage 2, content validity was evaluated by 7 nurses with expertise in ostomy and peristomal skin care. Convergent validity was evaluated by correlating the severity of peristomal skin complications to pain intensity. Discriminant validity was evaluated based on type and time of ostomy creation, presence of retraction, and preoperative stoma site marking. Finally, interrater reliability was evaluated using standardized photograph evaluation reproduced in the same sequence as the original English language version of the instrument, along with paired scores from assessment of adults living with an ostomy generated by an investigator and nurse data collectors. RESULTS: The Content Validity Index for the Ostomy Skin Tool was 0.83. Levels of mild agreements were obtained for the nurses' observations in the evaluation of peristomal skin complications using standardized photographs (κ= 0.314). In contrast, moderate to almost perfect agreements were obtained when scores were compared in the clinical setting (κ= 0.48-0.93, according to the domains). Positive correlations between the instrument and pain intensity (r = 0.44; P = .001) indicate convergent validity of the adapted version of the Ostomy Skin Tool. In contrast, analysis of discriminant validity was mixed and definitive conclusions about this form of construct validity cannot be made based on this study. CONCLUSION: This study supports convergent validity and interrater reliability of the adapted version of the Ostomy Skin Tool.

Deficiencies in reporting inclusion/exclusion criteria and characteristics of patients in randomized controlled trials of therapeutic interventions in pressure injuries: a systematic methodological review.

Wound care is a complex procedure and the related research may include many variables. Deficiencies in the sample inclusion and exclusion criteria may limit the generalizability of randomized controlled trials (RCTs) for wound patients in the real world. This study aimed to evaluate deficiencies in reporting the inclusion and exclusion criteria and the characteristics of patients in RCTs of pressure injuries (PI) therapeutic interventions. We conducted a systematic methodological review in which 40 full text RCTs of PI treatment interventions published in English, from 2008 to 2020, were identified. Data on the general characteristics of the included RCTs and data about inclusion/exclusion criteria and characteristics of patients were collected. The inclusion/exclusion criteria were categorized into five domains (definition of disease, precision, safety, ethical/legal and administrative). Study duration (in weeks) was 8.0 (quartile 1: 2.0; quartile 3: 48.0); only 5.0% of the trials mentioned race, skin colour or ethnicity, and 37.5% reported the duration of the wound. Only 9 (22.5%) studies reported the drugs that the included patients were using and 10 (25.0%) RCTs reported adverse events. The presence of the five domains was observed only in 12.5% of RCTs and only 12 (30.0%) had the precision domain. Much more research is required in systematic assessments of the external validity of trials because there is substantial disparity between the information that is provided by RCTs and the information that is required by clinicians. We concluded that there are deficiencies in reporting of data related to inclusion/exclusion criteria and characteristics of patients of RCTs assessing PI therapeutic interventions.

Skin tears in older adult residents of long-term care facilities: prevalence and associated factors.

OBJECTIVE: To determine the prevalence of skin tears, and demographic and clinical factors associated with their presence in older adult residents of long-term care facilities. METHOD: This observational, quantitative, cross-sectional, epidemiological study was conducted with older adult residents of three long-term care facilities in São Paulo, Brazil. For data collection, four instruments were used: a questionnaire assessing sociodemographic and clinical characteristics of the residents; and the Brazilian-Portuguese versions of the Mini-Mental State Examination, Skin Tear Audit Research (STAR) Skin Tear Classification System, and the Katz Index of Independence in Activities of Daily Living. RESULTS: A total of 69 residents took part in the study. The prevalence of skin tears was 11.6%. Skin tears were significantly associated with the presence of haematoma (odds ratio, OR=9.159; p=0.017) and actinic purpura (OR=6.265; p=0.033), which increased the odds of skin tear development nine-fold and six-fold, respectively. CONCLUSION: The findings agree with the international literature. Considering that this was the first epidemiological study on skin tears carried out in long-term care facilities for older adults in Brazil, its contribution lies in the systematisation of data collection and making data available on a field that has not yet been studied in this country.

The prevalence of skin tears and associated factors in hospitalised patients with cancer.

OBJECTIVE: Oncology patients are vulnerable to skin breakdown. The primary purpose of this study was to estimate the prevalence of skin tears (STs) in hospitalised patients with cancer and to explore related sociodemographic and clinical factors. METHOD: This was an observational, epidemiological, cross-sectional study conducted in an oncology hospital in the city of São Paulo. All STs were classified using the STAR Classification adapted and validated for Brazil. RESULTS: Of the 341 patients evaluated, 22 had STs, equating to a prevalence of 6.5%. A higher number of STs were noted on the lower limbs (26.9%) than on other body areas. The main factors associated with STs were the use of anticoagulants, the presence of ecchymosis and the use of incontinence briefs. CONCLUSION: This study contributed to a better understanding of the epidemiology of STs in hospitalised patients with cancer, as well as its associated factors. Results may inform nursing professionals with regard to the need to develop prevention strategies and early interventions.

The prevalence of skin lesions and associated factors in hospitalised adult patients with cancer.

OBJECTIVE: To assess the prevalence of skin lesions and evaluate the clinical and sociodemographic factors associated with their presence in hospitalised patients. METHOD: This descriptive, cross-sectional, correlational study was performed in inpatient units and intensive care units of a cancer hospital in São Paulo, Brazil, after approval by the Institutional Research Ethics Committee. Data from hospitalised adult patients with cancer were collected during physical examinations and from medical records. A Chi-squared test, univariate analysis, a logistic regression model with results expressed as odds ratio (OR) and 95% confidence intervals (CI), and Classification and Regression Tree (CART) analysis were used to evaluate the data. RESULTS: Of 341 patients, 80 had skin lesions, equating to an overall prevalence of 23.5%. The skin lesions included pressure injuries (10%), incontinence-associated dermatitis (6.7%), skin tears (6.5%), malignant wounds (3.8%) and complicated surgical wounds (3.2%). The factors associated with skin lesions in cancer patients were the use of disposable nappies (OR: 4.436) and age (59.1±15.1 years), according to the CART analysis, and the wearing of nappies (OR: 4.466, p<0.001), presence of ecchymosis (OR: 2.532, p<0.001) and infection (OR: 6.449, p=0.040), according to multiple regression analysis. CONCLUSION: This study contributed to knowledge about prevalence and associated factors of skin lesions in hospitalised patients with cancer, allowing the implementation of preventive measures.

Antifungal activity of bacterial strains from maize silks against Fusarium verticillioides.

Fusarium verticillioides is pathogenic to maize and mycotoxin-producer, causing yield losses, feed and food contamination, and risks to human and animal health. Endophytic (ISD04 and IPR45) and epiphytic (CT02 and IM14) bacteria from maize silks were tested in vitro and greenhouse against F. verticillioides and for hydrolytic enzyme production (cellulase, pectinase, protease, lipase, and chitinase). The strains preliminarily identified as Achromobacter xylosoxidans (ISD04), Pseudomonas aeruginosa (IPR45), and Bacillus velezensis (CT02 and IM14) by 16S gene sequencing. All strains showed antifungal activity in vitro with inhibition values from 58.5 to 100%; they changed hyphae morphology and inhibited the conidial germination by up to 100% (IPR45). The four strains produced at least one enzyme with antifungal activity. The microbiolized seeds reduced the fungal development in stored grains and stalk rot severity in the greenhouse by 72.6% (ISD04). These results highlight the potential of these strains as biocontrol agents against F. verticillioides.

Incidence of hospital-acquired pressure injury: A cohort study of adults admitted to public and private hospitals in Sao Paulo, Brazil.

This study aimed to estimate the incidence of hospital-acquired pressure injury (PI) and its risk factors in inpatient and intensive care units of five hospitals (two public and three private) in the city of Sao Paulo, Brazil. A 6-month follow-up prospective cohort study (n = 1937) was conducted from April to September 2013. Baseline and follow-up measurements included demographic and care information, as well as risk assessments for both undernutrition (NRS-2002) and PI (Braden scale). Poisson regression with robust variance was used for data analysis. A total of 633 patients (32.60%) showed risk for PI. The incidence rate of PI was of 5.9% (9.9% in public hospitals vs 4.1% in private hospitals) and was higher in intensive care units, compared to inpatient care units (10% vs 5.7%, respectively). Risk for PI increased with age (RR = 1.05; 95% CI 1.04-1.07); was higher in in public hospitals, compared to private hospitals (RR = 4.39; 95% CI 2.92-6.61); in patients admitted for non-surgical reasons compared to those admitted for surgical reasons (RR = 1.91; 95% CI 1.12-3.27); in patients with longer hospital stays (RR = 1.04; 95% CI 1.03-1.06); high blood pressure (RR = 1.76; 95% CI 1.17-2.64); or had a risk for undernutrition (RR = 3.51; 95% CI 1.71-7.24). Higher scores in the Braden scale was associated with a decreased risk of PI (RR = 0.79; 95% CI 0.75-0.83). The results of our study indicate that 5.9% of all patients developed PI and that the most important factors that nurses should consider are: patient age, care setting, length of hospitalization, comorbidities, reason for admission and nutrition when planning and implementing PI-preventative actions.

Development and psychometric property testing of a skin tear knowledge assessment instrument (OASES) in 37 countries.

AIM: To develop and psychometrically evaluate a skin tear knowledge assessment instrument (OASES). DESIGN: Prospective psychometric instrument validation study. METHOD: The skin tear knowledge assessment instrument was developed based on a literature review and expert input (N = 19). Face and content validity were assessed in a two-round Delphi procedure by 10 international experts affiliated with the International Skin Tear Advisory Panel (ISTAP). The instrument was psychometrically tested in a convenience sample of 387 nurses in 37 countries (April-May 2020). Validity of the multiple-choice test items (item difficulty, discriminating index, quality of the response alternatives), construct validity, and test-retest reliability (stability) were analysed and evaluated in light of international reference standards. RESULTS: A 20-item instrument, covering six knowledge domains most relevant to skin tears, was designed. Content validity was established (CVI = 0.90-1.00). Item difficulty varied between 0.24 and 0.94 and the quality of the response alternatives between 0.01-0.52. The discriminating index was acceptable (0.19-0.77). Participants with a theoretically expected higher knowledge level had a significantly higher total score than participants with theoretically expected lower knowledge (p < .001). The 1-week test-retest intraclass correlation coefficient (ICC) was 0.83 (95% CI = 0.78-0.86) for the full instrument and varied between 0.72 (95% CI = 0.64-0.79) and 0.85 (95% CI = 0.81-0.89) for the domains. Cohen's Kappa coefficients of the individual items ranged between 0.21 and 0.74. CONCLUSION: The skin tear knowledge assessment instrument is supported by acceptable psychometric properties and can be applied in nursing education, research, and practice to assess knowledge of healthcare professionals about skin tears. IMPACT: Prevention and treatment of skin tears are a challenge for healthcare professionals. The provision of adequate care is based on profound and up-to-date knowledge. None of the existing instruments to assess skin tear knowledge is psychometrically tested, nor up-to-date. OASES can be used worldwide to identify education, practice, and research needs and priorities related to skin tears in clinical practice.

Cultural adaptation and reliability of the ISTAP Skin Tear Classification System to Chilean Spanish.

OBJECTIVE: The International Skin Tear Advisory Panel (ISTAP) created the ISTAP Skin Tear Classification System with the aim of promoting a common and universal language to describe, classify and document skin tears, and increase awareness of the high prevalence of these wounds. Although there is a Spanish version of the ISTAP Skin Tear Classification System, the authors considered it relevant to have a specific Chilean Spanish version. The aim was to achieve the cultural adaptation of the ISTAP Skin Tear Classification System to Chilean Spanish, and verify its content validity and inter-rater reliability. METHOD: The study consisted of two phases: cultural adaptation of the ISTAP Skin Tear Classification System into Chilean Spanish, and validation of the culturally adapted system. A convenience sample of 150 health professionals classified 30 photographs of skin tears, using the same photographs used in the original ISTAP skin tear classification and validation study. Additionally, the clinical application of the classification system was tested among 20 nurses, who assessed and classified the skin tears (n=24) of hospitalised patients. For analysis of the inter-rater reliability, Fleiss' kappa was used. RESULTS: The differences found in the translation referred to a synonym of the terms 'skin' or 'cutaneous', and the terms 'flap' or 'tear'. Once analysed and discussed, the term 'desgarro' was maintained, which is the translation of the English term 'flap'. There is no equivalent term for 'skin tears' in Spanish, but consensus was reached by researchers and collaborators to use the phrase: 'desgarro de piel'. Once a consensus was reached on the wording for the translation, back-translation was completed and compared with the original English version and reviewed by the original author of the classification for accuracy. The content validity of the translated version of the ISTAP Skin Tear Classification System into Chilean Spanish showed a moderate agreement for the non-specialised nurses' group (0.4804) and for the specialised nurses' group (0.5308). Inter-rater reliability was achieved by obtaining a moderate agreement (Fleiss' kappa=0.53) and an almost perfect level of agreement for clinical application (Fleiss' kappa=0.83). CONCLUSION: The reported content validity and inter-rater reliability support the applicability of the cultural adaptation of the ISTAP Skin Tear Classification System to Chilean Spanish into practice.

Prevalence of diabetic foot ulcers and their associated factors in patients from public hospitals in manaus-am.

AIM: The purpose of this study was to identify and analyze the prevalence of diabetic foot ulcers (DFU) as well as associating factors in the city of Manaus, Amazonas State, Brazil. METHODS: This was an observational, epidemiological, cross-sectional study, point prevalence, with 229 adults' diabetic inpatients from seven hospitals. Written signed consent was obtained from all participants or their legal representative if they had a cognitive impairment. Sociodemographic and clinical data were collected through interviews and medical records. Each participant was examined by the research team to evaluate for foot deformity. RESULTS: Of the 229 patients diagnosed with DM, 60 presented DFU, resulting in a prevalence of 26.2 %. The logistic regression model that included all variables with a significance level of 5 % (p ≤ 0.05) shows: Patients with PAD were more likely to have DFU (OR = 2956; p = 0,01). The use of emollients (OR = 0.097; p < 0.001) and anticoagulants (OR = 0.149; p = 0.002) were related to reduced likelihood for developing DFU. CONCLUSION: This study contributes to a better understanding of DFU epidemiology in hospitalized patients, as well as the factors associated with them. The results are important for nursing in order to develop early prevention and intervention strategies.

Constipation in Hospitalized Patients: A Study of Prevalence and Associated Factors.

PURPOSE: The purpose of this study was to identify the prevalence of constipation in hospitalized patients, along with sociodemographic and clinical variables associated with its occurrence. DESIGN: Observational, cross-sectional study. SUBJECTS AND SETTINGS: The study sample comprised 343 adult patients hospitalized at a University Hospital in Sao Paulo, Brazil. METHODS: Point-prevalence data were collected on the same day each month over a 4-month period. Data were collected via interviews, physical examination, medical record review, and completion of a data collection form that queried sociodemographic data and incorporated the Bowel Function in the Community instrument. Patients were classified as constipated if they met 2 or more of the Rome III criteria. Logistic regression analyses were used to identify clinical or sociodemographic factors associated with constipation. RESULTS: Fifty-one patients had constipation, reflecting a point-prevalence of 14.8% (95% CI, 11.49-19.02). The prevalence of constipation was 15% in females (n = 29) and 14.7% in males (n = 22). Multivariable logistic regression showed that use of laxatives (OR = 9.98; 95% CI, 3.539-29.666) was associated with a higher likelihood of constipation. CONCLUSION: The prevalence of constipation in hospitalized adult patients was lower than that in previous studies. Patients using laxatives were more likely to experience constipation.

Adaptation of the City of Hope-Quality of Life-Ostomy Questionnaire From English to Brazilian Portuguese: A Validation Study.

PURPOSE: To culturally adapt the City of Hope-Quality of Life-Ostomy Questionnaire (COH-QOL-OQ) from English to Brazilian Portuguese and evaluate psychometric properties of the adapted instrument (internal consistency and construct validity). DESIGN: Methodological study to establish reliability and validity. SUBJECTS AND SETTING: The sample comprised 215 persons with stomas of any etiology who attended 1 of 3 specialized outpatient care center and 2 associations for persons with ostomies. Participants were residents of the state of Rio Grande do Sul, located in southeastern Brazil. METHODS: Techniques for cultural adaptation were carried out based on recommendations from the literature. We then evaluated the instrument's psychometric properties. Specifically, we evaluated construct (convergent and discriminant) validity and concurrent criterion validity via comparison of the adapted version of COH-QOL-OQ versus the WHOQOL-Bref (World Health Organization Quality of Life instrument). We also evaluated the internal consistency of the adapted COH-QOL-OQ, a measure of reliability. RESULTS: The internal consistency of the items was high with a Cronbach α of 0.92 for the total score and values ranging from 0.79 to 0.86 for the various domains of the COH-QOL-OQ. Confirmatory factorial analysis identified adjustment indexes to the acceptable model of adjustment for the COH-QOL-OQ model. Strong correlations between the COH-QOL-OQ and WHOQOL-Bref instrument domains confirmed the validity of the convergent construct. For the analysis of the concurrent criterion validity, the correlation coefficients between the score of item 16 and the other domains of COH-QOL-OQ ranged from 0.26 to 0.66. Analysis of the discriminate validity indicated that it was possible to isolate groups based on the temporal character of the stoma and time since ostomy surgery. CONCLUSIONS: The adapted version of COH-QOL-OQ demonstrates construct (convergent and discriminant) validity, concurrent criterion validity, and internal consistency (a measure of reliability) for evaluating health-related quality of life of persons with ostomies living in Brazil.

Regenerated oxidised cellulose versus calcium alginate in controlling bleeding from malignant breast cancer wounds: randomised control trial study protocol.

OBJECTIVE: Malignant wounds due to breast cancer can present with recurrent episodes of bleeding in the tumour tissue. This study will compare the efficacy of a calcium alginate dressing (Biatain, Coloplast A/S, Denmark) and a regenerated oxidised cellulose dressing (Surgicel, Ethicon, LLC, Puerto Rico). PROTOCOL: A total of 24 patients with breast cancer and bleeding, malignant wounds will be enrolled in the randomised, controlled, open study, conducted at a hospital specialising in breast cancer treatment and at another hospital specialising in palliative care. Patients over 18 years old, with bleeding and willing to undergo venipuncture for blood collection will be included. All enrolled patients will be randomised for allocation to an experimental group (regenerated oxidised cellulose dressing) or a control group (calcium alginate dressing). The main intervention will consist of the application of the haemostatic product, assessment of digital pressure and estimation of the time required for haemostasis. OUTCOMES: Key outcome measures will be the percentage of patients with haemostasis within 20 minutes, observation of haemostasis after three, five and 10 minutes, in addition to recurrence of bleeding and the quantity of product used. DISCUSSION: To our knowledge, this is the first study to evaluate the effectiveness of haemostatic products in malignant wounds. This type of wound is poorly explored in the literature and, among its signs and symptoms, bleeding is poorly studied. The completion of this study will provide a more robust rationale for clinical decision-making related to the control of bleeding in malignant breast cancer wounds in the context of evidence-based nursing practices.

Malignant Wounds in Hospitalized Oncology Patients: Prevalence, Characteristics, and Associated Factors.

Epidemiological and descriptive research on malignant wounds (MWs) is scarce. The objective of this study was to identify the prevalence of MWs and analyze the characteristics and associated factors of MWs in hospitalized patients at an oncological institution. An epidemiological, cross-sectional, and descriptive study, which was derived from a larger study that collected data on the prevalence of different types of wounds in 341 adults hospitalized in a large oncological hospital, was conducted. The present study comprehensively analyzed data related to MWs. Information was obtained through participant interviews, physical examination, and medical record review. The study was approved by the ethics committee of the institution where the study was conducted. Fourteen MWs were identified in 13 patients, who were primarily married (58%) and men (75%), with a mean age of 60.5 ± 15.1 years. Malignant wounds were predominantly located in the head and neck region (43%) and classified as 1N (50%) according to the Staging of Malignant Cutaneous Wounds instrument. Malignant wounds were characterized as painful (83.3%), with significant pain present during dressing changes (93%). The presence of MWs was associated with the use of antidepressants (odds ratio [OR] = 4.95; p = .012), upper-limb edema (OR = 8.39; p = .003), and infection (OR = 12.16; p = .051). The prevalence of MWs in hospitalized patients was 3.8%. Associated clinical variables were related to the degree of disease progression. This information provides evidence of the need for research identifying and investigating nursing interventions for patients with MW to assist with pain control during dressing changes.

Complicated Surgical Wounds and Associated Factors in Oncology Patients.

The objective of this study was to identify the occurrence of complicated surgical wounds (CSWs) and to analyze the associated factors in hospitalized patients at an oncology institution. This was an epidemiological, observational, cross-sectional, descriptive, and correlational study conducted in the intensive care and hospitalization units forming part of a large cancer hospital. Sociodemographic and clinical data were collected from medical records and physical examinations of the skin. Associations between the dependent variable (presence of CSWs) and the independent variables were obtained by chi-square tests and odds ratio (OR) calculations with a 95% confidence interval. Logistic regression (LASSO) was used to verify the possible predictors of the outcome. The sample consisted of 341 patients, specifically individuals who are White (46.9%), married (53.4%), and men (58.1%) with an average age of 59.2 years. Complicated surgical wounds were present in 3.2% of patients, and the most frequent types of complications were dehiscence (40%), infection (26.7%), and fistula (20%) present in the abdominal (40%), cephalic (26.7%), and cervical (13.3%) regions. Senile purpura, diaper use, and infection were the clinical variables associated with the occurrence of CSWs (p = .044, p = .001, and p < .001, respectively). Based on the logistic regression, the presence of infection (p < .001; OR = 90.8; 95% CI [18.42, 538.79]) persisted as a predictor of the occurrence of CSWs. From these observations, recommendations regarding best practices for the prevention of CSWs are made, specifically for patients with cancer.

Evaluation of the interaction between polymyxin B and Pseudomonas aeruginosa biofilm and planktonic cells: reactive oxygen species induction and zeta potential.

BACKGROUND: Although the most widely accepted mechanism of action for polymyxins is related to bacterial lysis via disruption, we hypothesized that this antimicrobial drug class could have other effects on Pseudomonas aeruginosa planktonic and sessile cells. Little is known regarding oxidative burst and zeta potential (ZP) data associated with the interaction between polymyxin B and P. aeruginosa cells. The present study evaluated endogenous reactive oxygen species (ROS) production and changes in the net charges of biofilm and planktonic cells in response to polymyxin B. RESULTS: Polymyxin B induced concentration-dependent killing at all concentrations tested in planktonic and sessile cells from P. aeruginosa strains. Sublethal concentrations of polymyxin B induced oxidative burst. ROS production was higher in resistant planktonic cells than in biofilm cells but this was not observed for susceptible cells. Moreover, no net surface charge alterations were observed in planktonic cells from a susceptible strain treated with polymyxin B, but a significant increase of ZP was noted in planktonic cells from a resistant strain. CONCLUSION: Oxidative burst generated by planktonic and sessile cells from P. aeruginosa strains against polymyxin B indicates that ROS may have an important role in the mechanism of action of this drug. ZP data revealed that electrostatic interactions of the cationic peptide with the anionic surface of the cells are strain-dependent. Therefore, we suggested that the intracellular effects of polymyxin B should be further investigated to understand polymyxin B-induced stress in P. aeruginosa.
