RESUMEN

Beer and spirits are two of the most consumed alcoholic beverages in the world, and their production generates enormous amounts of by-product materials. This ranges from spent grain, spent yeast, spent kieselguhr, trub, carbon dioxide, pot ale, and distilled gin spent botanicals. The present circular economy dynamics and increased awareness on resource use for enhanced sustainable production practices have driven changes and innovations in the management practices and utilization of these by-products. These include food product development, functional food applications, biotechnological applications, and bioactive compounds extraction. As a result, the brewing and distilling sector of the food and drinks industry is beginning to see a shift from conventional uses of by-products such as animal feed to more innovative applications. This review paper therefore explored some of these valorization initiatives and the current state of the art.

RESUMEN

BACKGROUND: The risk of congenital neurologic defects related to Zika virus (ZIKV) infection has ranged from 6 to 42% in various reports. The aim of this study was to estimate this risk among pregnant women with symptomatic ZIKV infection in French territories in the Americas. METHODS: From March 2016 through November 2016, we enrolled in this prospective cohort study pregnant women with symptomatic ZIKV infection that was confirmed by polymerase-chain-reaction (PCR) assay. The analysis included all data collected up to April 27, 2017, the date of the last delivery in the cohort. RESULTS: Among the 555 fetuses and infants in the 546 pregnancies included in the analysis, 28 (5.0%) were not carried to term or were stillborn, and 527 were born alive. Neurologic and ocular defects possibly associated with ZIKV infection were seen in 39 fetuses and infants (7.0%; 95% confidence interval, 5.0 to 9.5); of these, 10 were not carried to term because of termination of pregnancy for medical reasons, 1 was stillborn, and 28 were live-born. Microcephaly (defined as head circumference more than 2 SD below the mean for sex and gestational age) was detected in 32 fetuses and infants (5.8%), of whom 9 (1.6%) had severe microcephaly (more than 3 SD below the mean). Neurologic and ocular defects were more common when ZIKV infection occurred during the first trimester (24 of 189 fetuses and infants [12.7%]) than when it occurred during the second trimester (9 of 252 [3.6%]) or third trimester (6 of 114 [5.3%]) (P=0.001). CONCLUSIONS: Among pregnant women with symptomatic, PCR-confirmed ZIKV infection, birth defects possibly associated with ZIKV infection were present in 7% of fetuses and infants. Defects occurred more frequently in fetuses and infants whose mothers had been infected early in pregnancy. Longer-term follow-up of infants is required to assess any manifestations not detected at birth. (Funded by the French Ministry of Health and others; ClinicalTrials.gov number, NCT02916732 .).

RESUMEN

OBJECTIVE: While data management (DM) is an increasing responsibility of doctorally prepared nurses, little is understood about how DM education and expectations are reflected within student handbooks. The purpose of this study was to assess the inclusion of DM content within doctoral nursing student handbooks. METHODS: A list of 346 doctoral programs was obtained from the American Association of Colleges of Nursing (AACN). Program websites were searched to locate program handbooks, which were downloaded for analysis. A textual review of 261 handbooks from 215 institutions was conducted to determine whether DM was mentioned and, if so, where the DM content was located. Statistical analysis was performed to compare the presence of DM guidance by type of institution, Carnegie Classification, and the type of doctoral program handbook. RESULTS: A total of 1,382 codes were identified across data life cycle stages, most commonly in the handbooks' project requirements section. The most frequent mention of DM was in relation to collecting and analyzing data; the least frequent related to publishing and sharing data and preservation. Significant differences in the frequency and location of codes were identified by program type and Carnegie Classification. CONCLUSIONS: Nursing doctoral program handbooks primarily address collecting and analyzing data during student projects. Findings suggest limited education about, and inclusion of, DM life cycle content, especially within DNP programs. Collaboration between nursing faculty and librarians and nursing and library professional organizations is needed to advance the adoption of DM best practices for preparing students in their future roles as clinicians and scholars.

RESUMEN

BACKGROUND: Symptom burden associated with chronic kidney disease can be debilitating, with a negative effect on patient health-related quality of life. Latent class clustering analysis is an innovative tool for classifying patient symptom experience. OBJECTIVES: The aim of the study was to identify subgroups of patients at greatest risk for high symptom burden, which may facilitate development of patient-centered symptom management interventions. METHODS: In this cross-sectional analysis, baseline data were analyzed from 3,921 adults enrolled in the Chronic Renal Insufficiency Cohort Study from 2003 to 2008. Latent class cluster modeling using 11 items on the Kidney Disease Quality of Life symptom profile was employed to identify patient subgroups based on similar observed physical symptom response patterns. Multinomial logistic regression models were estimated with demographic variables, lifestyle and clinical variables, and self-reported measures (Kidney Disease Quality of Life physical and mental component summaries and the Beck Depression Inventory). RESULTS: Three symptom-based subgroups were identified, differing in severity (low symptom, moderate symptom, and high symptom). After adjusting for other variables in multinomial logistic regression, membership in the high-symptom subgroup was less likely for non-Hispanic Blacks and men. Other factors associated with membership in the high-symptom subgroup included lower estimated glomerular filtration rate, history of cardiac/cardiovascular disease, higher Beck Depression Inventory scores, and lower Kidney Disease Quality of Life physical and mental component summaries. DISCUSSION: Three symptom subgroups of patients were identified among patients with mild-to-moderate chronic kidney disease. Several demographic and clinical variables predicted membership in subgroups. Further research is needed to determine if symptom subgroups are stable over time and can be used to predict healthcare utilization and clinical outcomes.

RESUMEN

Objectives: Asynchronous virtual learning communities provide learners with the ability to enhance their learning and contribute to their peers' learning in a safe environment. However, the tone and content of learner comments, the level of engagement among learners, and the role of moderators have not been well studied within non-course-related virtual learning communities. Therefore, we sought to explore these characteristics using the NEJM Knowledge+ Question of the Week (NEJM Knowledge+ QoW) forum, a web-based asynchronous virtual learning community. Methods: We reviewed 73 NEJM Knowledge+ questions posted on the QoW forum between 2015 and 2016. We then selected three QoWs to analyze through a multistep coding process based on three broad criteria that aligned with our study aims. Results: Learner comments reflected both positive and critical tones, with learners sharing their own clinical practice and local experiences to contextualize their perspectives and reactions to both the QoW answer and the responses of other learners. Learners also commonly requested moderators to act as expert referees. Conclusion: Asynchronous virtual learning communities can engage learners by providing the opportunity to enhance their knowledge through responding to proposed medical scenarios and sharing their experiences in a discussion forum. Future work should examine the impact that geographic region has on asynchronous virtual learning communities and the role of moderators in shaping the learning experience.

RESUMEN

BACKGROUND: Few studies have evaluated technical efficiency of nursing care, and no such studies have been conducted in intensive care units (ICUs). PURPOSE: To explore relative technical efficiency of US ICUs and identify organizational factors associated with efficiency in providing quality of nursing care. METHODS: A total of 404 adult ICUs from the 2014 National Database of Nursing Quality Indicators were included. Data envelopment analysis was used to estimate technical efficiency, and multilevel modeling was employed to determine effects of organizational factors on efficiency. RESULTS: Nurse-to-patient ratio showed the strongest positive correlation with technical efficiency. Units in non-Magnet and small-size hospitals had higher technical efficiency than those in Magnet and medium- or large-size hospitals. CONCLUSIONS: A higher nurse-to-patient ratio greatly improved technical efficiency of nursing care in ICUs and the effect differed between hospitals. Administrators and policy makers can translate the study findings into management strategies to provide efficient nursing care in ICUs.

RESUMEN

INTRODUCTION: More than 5.5 million patients present to emergency departments in the United States annually for potential acute coronary syndrome (ACS); however, diagnosing ACS remains a challenge in emergency departments. Our aim was to describe the quality of symptoms (chest discomfort/description of pain, location/radiation, and overall symptom distress) reported by women and men ruled-in and ruled-out for ACS in emergency departments. METHODS: The sample consisted of 1,064 patients presenting to emergency departments with symptoms that triggered cardiac workups. Trained research staff obtained data using the ACS Patient Information Questionnaire upon patient presentation to emergency departments. RESULTS: The sample (n = 1,064) included 474 (44.55%) patients ruled-in and 590 (55.45%) patients ruled-out for ACS. Symptom distress was significantly higher in patients ruled-in versus ruled-out for ACS (7.3 ± 2.6 vs. 6.8 ± 2.5; P = 0.002) and was a significant predictor for an ACS diagnosis in men (odds ratio [OR], 1.10; confidence interval [CI], 1.03-1.17; P = 0.003). Women also reported more chest pressure (51.75% vs. 44.65; P = 0.02) compared with men, and chest pressure was a significant predictor for a diagnosis of ACS (OR, 1.61; CI, 1.03-2.53; P = 0.02). DISCUSSION: Higher levels of symptom distress may help ED personnel in making a decision to evaluate a patient for ACS, and the presence of chest pressure may aid in making a differential diagnosis of ACS.

RESUMEN

OBJECTIVE: The goal of this project was to decrease handoff delays from the emergency department (ED) as measured by ready to move (RTM)-to-occupied time. BACKGROUND: ED boarding compromises the quality, safety, and experience of patient care. Lack of standardized and transparent handoff communication contributes to boarding time. This process improvement initiative implemented a standardized electronic situation, background, assessment, and recommendation (eSBAR) format-based nursing handoff process from the ED to a medical unit. METHODS: Nursing staff were educated face-to-face regarding the initiative background, significance, and process. Outcomes were measured before and after eSBAR implementation. RESULTS: Before implementation, the house-wide average RTM-to-occupied time was 83.6 minutes. This decreased to 49 minutes (a 41.4% decrease) 3 weeks after implementation and improved further to 47 minutes at 10 months after implementation. No related patient safety or quality issues were identified. CONCLUSIONS: The use of an electronic, standardized handoff communication process resulted in decreased boarding time and increased bed flow efficiency.

RESUMEN

This study aimed to evaluate technical efficiency of US intensive care units and determine the effects of environmental factors on technical efficiency in providing quality of nursing care. Data were obtained from the 2014 National Database of Nursing Quality Indicators and the Centers for Medicare and Medicaid Services. Data envelopment analysis was used to estimate technical efficiency for each intensive care unit. Multilevel modeling was used to determine the effects of environmental factors on technical efficiency. Overall, Medicare Advantage penetration and hospital competition in a market did not create pressure for intensive care units to become more efficient by reducing their inputs. However, these 2 environmental factors showed positive influences on technical efficiency in intensive care units with certain levels of technical efficiency. The implications of the study results for management strategies and health policy may vary according to the levels of technical efficiency in intensive care units. Further studies are needed to examine why and how intensive care units with particular levels of technical efficiency are differently affected by certain environmental factors.

RESUMEN

We present a study of a range of cross-linked chitosan composites with potential antimicrobial applications. They were formed by cross-linking chitosan and siloxane networks and by introducing silver and gold nanoparticles (NPs). The aim was to investigate whether adding the metal NPs to the chitosan-siloxane composite would lead to a material with enhanced antimicrobial ability as compared to chitosan itself. The composites were synthesised in hydrogel form with the metal NPs embedded in the cross-linked chitosan network. Spectroscopic and microscopic techniques were employed to investigate the structural properties of the composite and the tensile strength of the structures was measured. It was found that the addition of metal NPs did not influence the mechanical strength of the composite. A crystal violet attachment assay results displayed a significant reduction in the attachment of E. coli to the cross-linked chitosan surfaces. Release profile tests suggest that the metal NPs do not contribute to the overall antimicrobial activity under neutral conditions. The contribution to the mechanical and antimicrobial properties from cross-linking with siloxane is significant, giving rise to a versatile, durable, antimicrobial material suitable for thin film formation, wound dressings or the coating of various surfaces where robustness and antimicrobial control are required.

RESUMEN

Limited research has been conducted on how nurses define or perceive "quality nursing care." We conducted focus groups to identify nurses' perceptions of quality care at a Midwestern academic medical center. Transcripts of the focus group sessions were analyzed using thematic analysis techniques, and 11 themes emerged: Leadership, Staffing, Resources, Timeliness, Effective Communication/Collaboration, Professionalism, Relationship-Based Care, Environment/Culture, Simplicity, Outcomes, and Patient Experience.

RESUMEN

AIM: The global increase in the rate of cesarean sections (CS) is currently an issue. We aimed to assess the rate of CS locally and to identify cases in which this procedure may have been avoidable. METHODS: In this prospective consecutive series, we analyzed the 478 CS carried out in our unit in 2009. We analyzed the characteristics of each case, and classified each as potentially avoidable or unavoidable. RESULTS: The total rate of CS was 24.0%, including 1.7% that was scored as potentially avoidable. Parity, gestational age at birth, birthweight, cases requiring cervical ripening, cases of labor induction, and CS during labor were all significantly higher or more frequent among potentially avoidable CS. Multivariate analysis indicated that the risk of potentially avoidable CS was positively associated with gestational age and tended to be negatively associated with parity. The main indications for potentially avoidable CS were cervical dystocia and abnormal fetal heart rate, and for unavoidable CS they were abnormal fetal heart rate and history of previous CS. CONCLUSION: Labor, especially when induced, seems to be the key period for the prevention of 'avoidable' CS. This is particularly important given that potentially avoidable CS are more frequently associated with uncomplicated pregnancies than are unavoidable CS. A woman's first CS increases the likelihood of CS for subsequent deliveries, so the prevention of the first CS is a key aim for reducing the overall rate of CS.

RESUMEN

The World Health Organization has acknowledged Patient Safety while receiving hospital care as a serious global public health issue, with patient empowerment and community engagement key to continuously improving safety and quality of care for the best possible clinical and patient outcomes. In Australia, the introduction of ten mandatory National Safety and Quality Health Service Standards in 2011 provided the catalyst for all Australian health facilities to review their systems. Standard 2: Partnering with Consumers required health facilities across Australia to assess commitment to, and capacity for consumer and community engagement and participation. At this time, the Royal Brisbane and Women's Hospital did not have a strategic perspective and understanding, or an organizational structure for engaging with consumers (patients, families, care givers and community members). The concept required a new model to replace the clinician-led model of healthcare historically featured in Australia, with a change in culture and core business. processes to partner with consumers at all levels of the system, from individual patient care through to participating in policy development, health service planning and delivery, and evaluation and measurement processes. The challenge for the hospital was to build a sustainable framework of engagement for a genuine patient-centered model of care informed by best practice, and provide leadership and commitment to developing as an area of excellence in patient engagement and experience. A successful and sustainable framework for consumer and community engagement has been embedded in the hospital, with resultant culture change, achieving accreditation across all core and developmental criteria for the partnering with consumer standards including several Met with Merit ratings.

RESUMEN

Due to their lack of toxicity to mammalian cells and good serum stability, proline-rich antimicrobial peptides (PR-AMPs) have been proposed as promising candidates for the treatment of infections caused by antimicrobial-resistant bacterial pathogens. It has been hypothesized that these peptides act on multiple targets within bacterial cells, and therefore the likelihood of the emergence of resistance was considered to be low. Here, we show that spontaneous Escherichia coli mutants resistant to pyrrhocoricin arise at a frequency of approximately 6 × 10(-7). Multiple independently derived mutants all contained a deletion in a nonessential gene that encodes the putative peptide uptake permease SbmA. Sensitivity could be restored to the mutants by complementation with an intact copy of the sbmA gene. These findings question the viability of the development of insect PR-AMPs as antimicrobials.

RESUMEN

BACKGROUND: Fatigue is a prevalent and disabling symptom associated with many acute and chronic conditions, including acute myocardial infarction and chronic heart failure. Fatigue has not been explored in patients with stable coronary heart disease (CHD). OBJECTIVES: The purpose of this partially mixed sequential dominant status study was to (a) describe fatigue in patients with stable CHD; (b) determine if specific demographic (gender, age, education, income), physiological (hypertension, hyperlipidemia), or psychological (depressive symptoms) variables were correlated with fatigue; and (c) determine if fatigue was associated with health-related quality of life. The theory of unpleasant symptoms was used as a conceptual framework. METHODS: Patients (N = 102) attending two cardiology clinics completed the Fatigue Symptom Inventory, Patient Health Questionnaire-9, and Medical Outcomes Study Short Form-36 to measure fatigue, depressive symptoms, and health-related quality of life. Thirteen patients whose interference from fatigue was low, moderate, or high participated in qualitative interviews. RESULTS: Forty percent of the sample reported fatigue more than 3 days of the week lasting more than one half of the day. Lower interference from fatigue was reported on standardized measures compared with qualitative interviews. Compared with men, women reported a higher fatigue intensity (p = .003) and more interference from fatigue (p = .007). In regression analyses, depressive symptoms were the sole predictor of fatigue intensity and interference. DISCUSSION: Patients with stable CHD reported clinically relevant levels of fatigue. Patients with stable CHD may discount fatigue as they adapt to their symptoms. Relying solely on standardized measures may provide an incomplete picture of fatigue burden in patients with stable CHD.

RESUMEN

INTRODUCTION: Several analytical methods exist for the determination of sulphoraphane or sulphoraphane nitrile from biological matrices and plant extracts. However, no UPLC-MS/MS method exists for the simultaneous detection of both. OBJECTIVE: To develop and validate an UPLC-MS/MS method for the simultaneous analysis of sulphoraphane and sulphoraphane nitrile from Brassica oleracea L. ssp. italica METHODS: This method was developed utilising an Acquity BEH C8 column with gradient elution combined with tandem mass spectrometry, using positive electrospray ionisation in multiple reaction monitoring mode. RESULTS: The retention times for sulphoraphane and sulphoraphane nitrile were 0.4 and 0.6 min respectively, and total run time was 3 min. The method was validated for linearity, sensitivity, precision, accuracy, matrix effects and recovery. The method was employed to determine glucoraphanin hydrolysis products in broccoli and the predominant product was found to vary depending on the variety tested. It was also applied to the accurate determination of sulphoraphane and sulphoraphane nitrile in broccoli samples hydrolysed under different conditions. It was observed that the formation of sulphoraphane and sulphoraphane nitrile was influenced by the temperature of the reaction. CONCLUSION: The validated UPLC-MS/MS method for simultaneous detection of sulphoraphane and sulphoraphane nitrile was shown to be applicable to broccoli plants and is expected to be applicable to other cruciferous sources.

RESUMEN

BACKGROUND: The fish-processing industry generates significant amounts of waste and by-products that are usually discarded. This study investigated the preparation of bioactive gelatine peptides from fish skin. Gelatine was extracted from mackerel (Scomber scombrus) skin and hydrolysed by pepsin for 1, 2, 6 and 24 h. All hydrolysates were screened for antioxidant, ACE-inhibitory and antithrombotic activities. RESULTS: Gelatine peptides obtained after 24 h of hydrolysis exhibited the highest antioxidant activity (DPPH reduction ∼80%, FRAP ∼130 µmol Trolox equivalent L(-1) ). These hydrolysates had high ACE-inhibitory activity (>70%) and were able to significantly (P < 0.05) inhibit platelet aggregation by about 30%, corresponding to moderate antithrombotic activity. CONCLUSION: The bioactive properties were mainly due to the presence of low-molecular-weight peptides of 337 and 423 Da.

RESUMEN

Background: While nurses are strategically placed to support the achievement of universal health, their practice may not always be informed by evidence, especially in a context where research evidence is not commonly used to inform practice.Objective/Aim/Hypothesis: Improve management of clients with CNCDs in Caribbean community through evidence-based practice (EBP) capacity building workshops.Design/Methods: A descriptive, quantitative design was used for this study. Participants included Community Based Nurses who attended an initial and recall workshop on EBP in a Caribbean island. All participants were included as the sample. Data were collected as a Pre-Test and Post Test before the initial workshop and at the recall workshop. Analysis was done quantitatively. Since the sample was small, only descriptive statistics were used.Results: Data showed 64% of participants had no experience with EBP, 55% needed more essential resources to participate in EBP and 55% recognized a need to include EBP to change their clinical practice effectively.Conclusions: The nurses and district supervisors observed a high level of interest and commitment to initiating and completing EBP projects. However, the reality of significant workplace demands, and limitations in consistent logistical and supervisory support impacted long-term sustainability.
