Effect of cooking on structural changes in the common black bean (Phaseolus vulgaris var. Jamapa).

The cooking process is fundamental for bean consumption and to increase the bioavailability of its nutritional components. The study aimed to determine the effect of cooking on bean seed coat through morphological analyses with different microscopy techniques and image analyses. The chemical composition and physical properties of raw black bean (RBB) and cooked black bean (CBB) seeds were determined. The surface and cross-sectional samples were studied by Optical microscopy (OM), environmental scanning electron microscopy (ESEM), atomic force microscopy (AFM) and confocal laser scanning microscopy (CLSM). The composition of samples showed significant differences after the cooking process. OM images and gray level co-occurrence matrix algorithm (GLCM) analysis indicated that cuticle-deposited minerals significantly influence texture parameters. Seed coat surface ESEM images showed cluster cracking. Texture fractal dimension and lacunarity parameters were effective in quantitatively assessing cracks on CBB. AFM results showed arithmetic average roughness (Ra) (121.67 nm) and quadratic average roughness (Rq) (149.94 nm). The cross-sectional ESEM images showed a decrease in seed coat thickness. The CLSM results showed an increased availability of lipids along the different multilayer tissues in CBB. The results generated from this research work offer a valuable potential to carry out a strict control of bean seed cooking at industrial level, since the structural changes and biochemical components (cell wall, lipids and protein bodies) that occur in the different tissues of the seed are able to migrate from the inside to the outside through the cracks generated in the multilayer structure that are evidenced by the microscopic techniques used.

Conduct and reporting of multivariate network meta-analyses: a scoping review.

OBJECTIVES: Combining multivariate and network meta-analysis methods simultaneously in a multivariate network meta-analysis (MVNMA) provides the methodological framework to analyze the largest amount of evidence relevant to decision-makers (i.e., from indirect evidence and correlated outcomes). The objectives of this scoping review were to summarize the characteristics of MVNMAs published in the health sciences literature and map the methodological guidance available for MVNMA. STUDY DESIGN AND SETTING: We searched MEDLINE, Embase, and the Cumulative Index to Nursing and Allied Health Literature from inception to 28 August 2023, along with citations of included studies, for quantitative evidence syntheses that applied MVNMA and articles addressing MVNMA methods. Pairs of reviewers independently screened potentially eligible studies. Collected data included bibliographic, methodological, and analytical characteristics of included studies. We reported results as total numbers, frequencies, and percentages for categorical variables and medians and interquartile ranges for continuous variables that were not normally distributed. RESULTS: After screening 1,075 titles and abstracts, and 112 full texts, we included 38 unique studies, of which, 10 were quantitative evidence syntheses that applied MVNMA and 28 were articles addressing MVNMA methods. Among the 10 MVNMAs, the first was published in 2013, four used studies identified from already published systematic reviews, and eight addressed pharmacological interventions, which were the most common interventions. They evaluated interventions for metastatic melanoma, colorectal cancer, prostate cancer, oral hygiene, disruptive behavior disorders, rheumatoid arthritis, narcolepsy, type 2 diabetes, and overactive bladder syndrome. Five MVNMAs analyzed two outcomes simultaneously, and four MVNMAs analyzed three outcomes simultaneously. Among the articles addressing MVNMA methods, the first was published in 2007 and the majority provided methodological frameworks for conducting MVNMAs (26/28, 93%). One study proposed criteria to standardize reporting of MVNMAs and two proposed items relevant to the quality assessment of MVNMAs. Study authors used data from 18 different illnesses to provide illustrative examples within their methodological guidance. CONCLUSIONS: The application of MVNMA in the health sciences literature is uncommon. Many methodological frameworks are published; however, standardization and specific criteria to guide reporting and quality assessment are lacking. This overview of the current landscape may help inform future conduct of MVNMAs and research on MVNMA methods.

Nanosuspensions as carriers of active ingredients: Chemical composition, development methods, and their biological activities.

Nanosuspensions (NSps) are colloidal dispersions of particles that have the potential to solve the delivery problems of active ingredients associated with their low solubility in water or instability due to environmental factors. It is essential to consider their chemical composition and preparation methods because they directly influence drug loading, size, morphology, solubility, and stability; these characteristics of nanosuspensions influence the delivery and bioavailability of active ingredients. NSps provides high loading of drugs, protection against degrading agents, rapid dissolution, high particle stability, and high bioavailability of active ingredients across biological membranes. In addition, they provide lower toxicity compared to other nanocarriers, such as liposomes or polymeric nanoparticles, and can modify the pharmacokinetic profiles, thus improving their safety and efficacy. The present review aims to address all aspects related to the composition of NSps, the different methods for their production, and the main factors affecting their stability. Moreover, recent studies are described as carriers of active ingredients and their biological activities.

Mycobacterium tuberculosis ß-lactamase variant reduces sensitivity to ampicillin/avibactam in a zebrafish-Mycobacterium marinum model of tuberculosis.

The ß-lactamase of Mycobacterium tuberculosis, BlaC, hydrolyzes ß-lactam antibiotics, hindering the use of these antibiotics for the treatment of tuberculosis. Inhibitors, such as avibactam, can reversibly inhibit the enzyme, allowing for the development of combination therapies using both antibiotic and inhibitor. However, laboratory evolution studies using Escherichia coli resulted in the discovery of single amino acid variants of BlaC that reduce the sensitivity for inhibitors or show higher catalytic efficiency against antibiotics. Here, we tested these BlaC variants under more physiological conditions using the M. marinum infection model of zebrafish, which recapitulates hallmark features of tuberculosis, including the intracellular persistence of mycobacteria in macrophages and the induction of granuloma formation. To this end, the M. tuberculosis blaC gene was integrated into the chromosome of a blaC frameshift mutant of M. marinum. Subsequently, the resulting strains were used to infect zebrafish embryos in order to test the combinatorial effect of ampicillin and avibactam. The results show that embryos infected with an M. marinum strain producing BlaC show lower infection levels after treatment than untreated embryos. Additionally, BlaC K234R showed higher infection levels after treatment than those infected with bacteria producing the wild-type enzyme, demonstrating that the zebrafish host is less sensitive to the combinatorial therapy of ß-lactam antibiotic and inhibitor. These findings are of interest for future development of combination therapies to treat tuberculosis.

Steering the Titanic: One tertiary care children's hospital's experience navigating safe sleep for hospitalized infants.

BACKGROUND: Sudden Unexpected Infant Death (SUID) is the leading cause of death in infants 1 month to 1 year of age in the United States. Despite extensive efforts in research and public education, rates of sleep-related infant death have plateaued since the late-1990s, largely due to unsafe sleep practices and environments. LOCAL PROBLEM: A multidisciplinary team assessed our institution's compliance with its own infant safe sleep policy. Data was collected on infant sleep practices, nurses' knowledge and training on the hospital policy, and teaching practices for parents and caregivers of hospitalized infants. Zero crib environments from our baseline observation met all the American Academy of Pediatrics recommendations for infant safe sleep. METHODS: A comprehensive safe sleep program was implemented in a large pediatric hospital system. The purpose of this quality improvement project was to improve compliance with safe sleep practice from 0% to 80%, documentation of infant sleep position and environment every shift from 0% to 90%, and documentation of caregiver education from 12% to 90% within 24 months. INTERVENTIONS: Interventions included revision of hospital policy, staff education, family education, environmental modifications, creation of a safe sleep taskforce, and electronic health record modifications. RESULTS: Documented compliance with infant safe sleep interventions at the bedside improved from 0% to 88%, while documentation of family safe sleep education improved from 12% to 97% during the study period. CONCLUSIONS: A multifaceted, multidisciplinary approach can lead to significant improvements in infant safe sleep practices and education in a large tertiary care children's hospital system.

Beyond demographics: Attitudinal barriers to the mental health service use of immigrants in the U.S.

Immigrants are at greater risk for mental health concerns but are less likely to use mental health services than their U.S.-born counterparts. Efforts to understand these disparities have focused on demographic characteristics while largely ignoring the role of immigrants' beliefs and values. This review synthesizes the research on the mental health-related beliefs and values associated with the mental health service underutilization of each major U.S. immigrant group. Results revealed two overarching attitudinal themes common to several immigrant groups and several attitudinal barriers unique to individual groups. They also elucidated several areas for additional research and highlighted the need to target these beliefs and values in public health efforts promoting MHS use among U.S. immigrants.

Healing of a chronic ulcer of the lower limb of venous origin with fresh human amniochorionic membrane allograft / Curación de úlcera venosa crónica de la pierna con aloinjerto de membrana amniocoriónica humana fresca

In its fresh state, the amniochorionic membrane contains various multipotential cells, growth factors, and extracellular matrix proteins that contribute to the healing of chronic vascular ulcers. To demonstrate its effectiveness, a fresh human placental membrane allograft was applied to a chronic venous ulcer in the lower limb of an 89-year-old female patient with a 12 x 10 cm ulcerated lesion of 40 years of evolution in the malleolar area of her left lower limb. Sixty days after the graft, the ulcer was healed in 100% of its surface and a light pink scar on the edges indicated possible pigmentation. Fresh human amniochorionic membrane allograft is a therapeutic alternative for the healing of refractory chronic vascular ulcers of the lower extremities.

Phenolic compounds profile by UPLC-ESI-MS in black beans and its distribution in the seed coat during storage.

Hard to cook phenomenon results from inadequate post-harvest storage of the bean associated with the microstructure and changes in seed color and texture. The aim of this study was to evaluate the physical and chemical properties, identify the phenolic compounds and their relationship with the black bean seed coat microstructure during 270 days at 30 °C and 70% r. h. The water absorption capacity decrease to 12.19% that induced changes in seed texture observed by increasing the hardness from 5.42 to 19.96 N. A total of 37 compounds were identified by UPLC-ESI-MS and the changes in phenolic profile during storage period contribute to the seed coat color saturation. The identification of flavonoids, hydroxybenzoic and hydroxycinnamic acids, as well as distribution of condensed tannins in the seed coat, the changes in physical properties evidenced by seed darkening and hardening contribute to the seed coat impermeability.

Intestinal Organoids: New Tools to Comprehend the Virulence of Bacterial Foodborne Pathogens.

Foodborne diseases cause high morbidity and mortality worldwide. Understanding the relationships between bacteria and epithelial cells throughout the infection process is essential to setting up preventive and therapeutic solutions. The extensive study of their pathophysiology has mostly been performed on transformed cell cultures that do not fully mirror the complex cell populations, the in vivo architectures, and the genetic profiles of native tissues. Following advances in primary cell culture techniques, organoids have been developed. Such technological breakthroughs have opened a new path in the study of microbial infectious diseases, and thus opened onto new strategies to control foodborne hazards. This review sheds new light on cellular messages from the host-foodborne pathogen crosstalk during in vitro organoid infection by the foodborne pathogenic bacteria with the highest health burden. Finally, future perspectives and current challenges are discussed to provide a better understanding of the potential applications of organoids in the investigation of foodborne infectious diseases.

Exploring nurse beliefs and perceived readiness for system wide integration of evidence based practice in a large pediatric health care system.

PURPOSE: Evidence-based practice (EBP) within healthcare leads to improved patient outcomes, high-quality care, job satisfaction, reduced turnover, professional autonomy, and validates nursing practice. Although a plethora of research focuses on implementing EBP, there has been little attention on assessing organizational readiness for integration. The primary aims of this study were to explore nursing beliefs and attitudes about EBP and explore the culture and readiness among pediatric nurses for system-wide integration of EBP. DESIGN AND METHODS: This study was a quantitative, cross-sectional survey-based study conducted at a large pediatric health system. RESULTS: Overall pediatric nurses had a mean score of 61.78 ± 9.32 on the EBPB (n = 396). Results of the EBPB Scale and OCRSIEP showed no statistical difference between nursing roles EBPB scores; however, nursing leaders had higher scores than any other nursing role. The OCRSIEP had a mean score of 84.98 ± 19.53 (n = 388). CONCLUSIONS: Findings suggest that pediatric nurses believe that EBP results in the best clinical care for patients and can improve clinical care, but they lack the skills and time necessary to engage in the process. This study found that increasing awareness of EBP resources and developing EBP competencies may assist pediatric nurse leaders with EBP integration into daily practice. PRACTICE IMPLICATIONS: Increasing visibility and competencies of EBP may positively impact organizational readiness by increasing confidence needed to remove identified barriers and engrain EBP in the organization's culture.

Evaluation of an Educational Outreach and Audit and Feedback Program to Reduce Continuous Pulse Oximetry Use in Hospitalized Infants With Stable Bronchiolitis: A Nonrandomized Clinical Trial.

Importance: National guidelines recommend against continuous pulse oximetry use for hospitalized children with bronchiolitis who are not receiving supplemental oxygen, yet guideline-discordant use remains high. Objectives: To evaluate deimplementation outcomes of educational outreach and audit and feedback strategies aiming to reduce guideline-discordant continuous pulse oximetry use in children hospitalized with bronchiolitis who are not receiving supplemental oxygen. Design, Setting, and Participants: A nonrandomized clinical single-group deimplementation trial was conducted in 14 non-intensive care units in 5 freestanding children's hospitals and 1 community hospital from December 1, 2019, through March 14, 2020, among 847 nurses and physicians caring for hospitalized children with bronchiolitis who were not receiving supplemental oxygen. Interventions: Educational outreach focused on communicating details of the existing guidelines and evidence. Audit and feedback strategies included 2 formats: (1) weekly aggregate data feedback to multidisciplinary teams with review of unit-level and hospital-level use of continuous pulse oximetry, and (2) real-time 1:1 feedback to clinicians when guideline-discordant continuous pulse oximetry use was discovered during in-person data audits. Main Outcomes and Measures: Clinician ratings of acceptability, appropriateness, feasibility, and perceived safety were assessed using a questionnaire. Guideline-discordant continuous pulse oximetry use in hospitalized children was measured using direct observation of a convenience sample of patients with bronchiolitis who were not receiving supplemental oxygen. Results: A total of 847 of 1193 eligible clinicians (695 women [82.1%]) responded to a Likert scale-based questionnaire (71% response rate). Most respondents rated the deimplementation strategies of education and audit and feedback as acceptable (education, 435 of 474 [92%]; audit and feedback, 615 of 664 [93%]), appropriate (education, 457 of 474 [96%]; audit and feedback, 622 of 664 [94%]), feasible (education, 424 of 474 [89%]; audit and feedback, 557 of 664 [84%]), and safe (803 of 847 [95%]). Sites collected 1051 audit observations (range, 47-403 per site) on 709 unique patient admissions (range, 31-251 per site) during a 3.5-month period of continuous pulse oximetry use in children with bronchiolitis not receiving supplemental oxygen, which were compared with 579 observations (range, 57-154 per site) from the same hospitals during the baseline 4-month period (prior season) to determine whether the strategies were associated with a reduction in use. Sites conducted 148 in-person educational outreach and aggregate data feedback sessions and provided real-time 1:1 feedback 171 of 236 times (72% of the time when guideline-discordant monitoring was identified). Adjusted for age, gestational age, time since weaning from supplemental oxygen, and other characteristics, guideline-discordant continuous pulse oximetry use decreased from 53% (95% CI, 49%-57%) to 23% (95% CI, 20%-25%) (P < .001) during the intervention period. There were no adverse events attributable to reduced monitoring. Conclusions and Relevance: In this nonrandomized clinical trial, educational outreach and audit and feedback deimplementation strategies for guideline-discordant continuous pulse oximetry use among hospitalized children with bronchiolitis who were not receiving supplemental oxygen were positively associated with clinician perceptions of feasibility, acceptability, appropriateness, and safety. Evaluating the sustainability of deimplementation beyond the intervention period is an essential next step. Trial Registration: ClinicalTrials.gov Identifier: NCT04178941.

Cladodes: Chemical and structural properties, biological activity, and polyphenols profile.

The nopal cactus is an essential part of the Mexican diet and culture. The per capita consumption of young cladodes averages annually to 6.4 kg across the nation. In addition to contributing to the country's food culture, the nopal is considered a food with functional characteristics since, in addition to providing fiber, an important group of polyphenolic compounds is present, which has given cladodes to be considered a healthy food, for what they have been incorporated into the diet of Mexican people and many other countries worldwide. Research suggests that polyphenols from cladodes act as antioxidants and antidiabetics. This review studies the main phenolic components in cladodes and summarizes both conventional and novel methods to identify them.

Incorporating a Civility Program Into a Healthcare System: Journey or Expedition?

PURPOSE/OBJECTIVES: Incivility contributes to employee dissatisfaction, turnover, patient errors, and a disrespectful culture. Turnover rates and employee exit interviews alerted hospital leaders to uncivil behaviors exhibited by staff. A clinical nurse specialist (CNS) team captured this as an opportunity to create a civility program to develop team cohesiveness and improve patient safety. The purpose of this process improvement project was to identify uncivil behaviors in a pediatric hospital. DESCRIPTION OF THE PROJECT/PROGRAM: Using the Plan-Do-Study-Act model, an interprofessional team led by CNSs collaborated on a program to assess, intervene, and evaluate a program to improve civility. A preprogram survey, the Negative Acts Questionnaire-Revised, was used to assess staff perceptions of their work environment. Staff attended an education program on ways to recognize and intervene in situations involving less than standard civil behavior. Classes included communication application in uncivil situations using scenarios paired with evidence-based practice articles. Unit leaders reset behavioral expectations learned from a leader-specific class on managing unproductive behaviors. OUTCOME: Staff completed a postprogram Negative Acts Questionnaire-Revised survey 6 months after conclusion of classes. Survey results indicated the civility program effected a reduction in frequency of negative behaviors indicating an overall positive shift in workplace civility. CONCLUSION: The program provided staff with tools to recognize and intervene for improving civility, which impacted the overall work environment and patient safety.

Purposeful Hourly Rounding to Decrease Peripheral Intravenous Infiltrations and Extravasations in Pediatrics.

PURPOSE: Pediatric patients are at high risk for peripheral intravenous infiltrations and extravasations (PIVIE) resulting in patient harm. Structured hourly rounding has demonstrated to improve quality outcomes. The purpose of this quality improvement project was to implement structured hourly rounding to decrease the median rate of moderate PIVIE rates from 3.13 to 2.58 per thousand patient days over a 6-month time period in pediatric patients with infusing continuous IV fluids. DESIGN AND METHODS: A pilot was conducted to hardwire hourly assessments for peripheral intravenous lines (PIV) in pediatric patients with continuous fluids utilizing a structured hourly rounding process. Bedside nurses utilized the P.A.T.H. model to assess pain management (P), assess PIVs for early PIVIE recognition (A), address things patient and family may need (T), and reduce the occurrence in hospital acquired conditions (H). Data was collected on unit nurse sensitive indicators and compliance to hourly rounding. RESULTS: Structured hourly rounding using the P.A.T.H. model successfully hardwired hourly PIV assessments. The unit reduced their median moderate PIVIE rate to 1.83 per thousand patient days, an 41% improvement. The pilot also had positive unintended consequences of improved pain reassessment from 67% to 100%, increased patient satisfaction scores of 67% to 97% and reduced patient falls by 29%. CONCLUSIONS: Structured hourly rounding using the P.A.T.H. model can positively hardwire hourly PIV assessments in pediatric patients. PRACTICE IMPLICATIONS: Sustainability of hourly rounding requires leadership support and nursing commitment to impact quality metrics. Organizations should consider implementing focused hourly rounding to address PIVIEs.

Bean phenolic compound changes during processing: Chemical interactions and identification.

The common bean (Phaseolus vulgaris L.) represents one of the main crops for human consumption, due to its nutritional and functional qualities. Phenolic compounds have beneficial health effects, and beans are an essential source of these molecules, being found mainly in the seed coat and its color depends on the concentration and type of phenolic compounds present. The bean during storage and processing, such as cooking, germination, extrusion, and fermentation, undergoes physical, chemical, and structural changes that affect the bioavailability of its nutrients; these changes are related to the interactions between phenolic compounds and other components of the food matrix. This review provides information about the identification and quantification of phenolic compounds present in beans and the changes they undergo during processing. It also includes information on the interactions between the phenolic compounds and the components of the bean's cell wall and the analytical methods used to identify the interactions of phenolic compounds with macromolecules.

Characterization of a pluripotent stem cell-derived matrix with powerful osteoregenerative capabilities.

Approximately 10% of fractures will not heal without intervention. Current treatments can be marginally effective, costly, and some have adverse effects. A safe and manufacturable mimic of anabolic bone is the primary goal of bone engineering, but achieving this is challenging. Mesenchymal stem cells (MSCs), are excellent candidates for engineering bone, but lack reproducibility due to donor source and culture methodology. The need for a bioactive attachment substrate also hinders progress. Herein, we describe a highly osteogenic MSC line generated from induced pluripotent stem cells that generates high yields of an osteogenic cell-matrix (ihOCM) in vitro. In mice, the intrinsic osteogenic activity of ihOCM surpasses bone morphogenic protein 2 (BMP2) driving healing of calvarial defects in 4 weeks by a mechanism mediated in part by collagen VI and XII. We propose that ihOCM may represent an effective replacement for autograft and BMP products used commonly in bone tissue engineering.

ABSTRACT Dryophthorinae is a relatively small weevil subfamily associated mainly with monocots. There are species in Colombia considered pests in the palm and Musaceae crops. In this document, a list of the species of Dryophthoridae for the departments of the Colombian Caribbean coast is presented, based on data from entomological collections and literature review. For the region, 11 species were recorded: Cosmopolites sordidus, Dynamis borassi, Mesocordylus striatus, Metamasius hemipterus, M. hebetatus, Polytus mellerborgii, Rhynchophorus palmarum, Rhodobaenus sp., Rhinostomus barbirostris, Sitophilus zeamais and S. oryzae, some of which are registered for the first time for the area. The importance of systematically sampling this group, and studies leading to improve knowledge about their distribution and biology, as well as its impact on agricultural production and their potential as pests in the country, are discussed.

Promoting Equity and Resilience: Wellness Navigators' Role in Addressing Adverse Childhood Experiences.

OBJECTIVE: Adverse childhood experiences (ACEs) have demonstrable negative effects on long-term physical and mental health. Racial and ethnic minority children disproportionally experience ACEs due to the impacts of structural inequality and discrimination, which could drive health disparities. Pediatric settings offer an opportune context to address ACEs and improve health equity, and to link families to the necessary resources to promote resilience. Wellness navigators (WNs), who can reflect patients' cultural, linguistic, and other shared characteristics, have the potential to improve patient care and integrated behavioral health services to mitigate the public health impact of ACEs. In the current study, bilingual and bicultural WNs helped to deliver an ACEs screening and response to predominately Latinx patients in a pediatric service setting. METHODS: Quantitative data on referrals made by WNs and qualitative interviews were analyzed to understand the role of WNs in ACEs screening. RESULTS: Among families (infants and caregivers) that screened positive for ACEs, WNs addressed social determinants of health and, based on individual needs assessments, made referrals to community resources in over half of the cases. Insurance, childcare, and housing were the most frequent referral sources. WNs supported caregivers in initiating services with 94% of the referrals that were made. Qualitative interviews with medical providers and caregivers underscored WNs' role in the ACEs screening process. Implications for ACEs screening, trauma-responsive pediatric care, and integrating WNs into an integrated behavioral health team are discussed.

A Zika Reference Panel for Molecular-Based Diagnostic Devices as a US Food and Drug Administration Response Tool to a Public Health Emergency.

In 2015, Zika virus (ZIKV) appeared as an emerging pathogen, generating a global and urgent need for accurate diagnostic devices. During this public health crisis, several nucleic acid testing (NAT)-based Zika assays were submitted to the US Food and Drug Administration (FDA) for Emergency Use Authorization. The FDA's Center for Devices and Radiological Health, in collaboration with the FDA's Center for Biologics Evaluation and Research, responded to this Zika emergency by developing and producing a reference panel (RP) for Zika RNA (Zika FDA-RP) suitable for performance assessment of ZIKV NAT-based in vitro diagnostic devices. Reference panels are a fundamental tool for performance assessment of molecular tests. The panel is composed of five vials: two different heat-inactivated ZIKV strains (PRVABC59 and FSS13025) in concentrated stocks and three blinded concentrations prepared from those strains. The Zika FDA-RP was shared with developers who had devices in the final stages of validation. In vitro diagnostic developers tested the Zika FDA-RP using the FDA-provided protocol. Depending on sample type, 85% (12/14) of the NAT assays had analytical sensitivities between 500 and 5000 RNA NAT-detectable units/mL (NDUs/mL). One device showed better performance (100 NDUs/mL), and another one showed lower performance (10,000 to 30,000 NDUs/mL). Vials of the Zika FDA-RP are available on request to developers who have interacted with the FDA through the review process.
