Combining ability analysis in bitter gourd (Momordica charantia L. ) for potential quality improvement / Análise de capacidade de combinação em cabaça-amarga (Momordica charantia L. ) para melhoria potencial da qualidade

Abstract Combining ability analysis provides useful information for the selection of parents, also information regarding the nature and magnitude of involved gene actions. Crops improvement involves strategies for enhancing yield potentiality and quality components. Targeting the improvement of respective characters in bitter gourd, combining ability and genetic parameters for 19 characters were estimated from a 6×6 full diallel analysis technique. The results revealed that the variances due to general combining ability (GCA) and specific combining ability (SCA) were highly significant for most of the important characters. It indicated the importance of both additive and non-additive gene actions. GCA variances were higher in magnitude than SCA variances for all the characters studied indicating the predominance of the additive gene effects in their inheritance. The parent P2 (BG 009) appeared as the best general combiner for earliness; P1 (BG 006) for number of fruits, average single fruit weight and fruit yield; P4 (BG 027) for node number of first female flower and days to seed fruit maturity; P3 (BG 011) for fruit length and thickness of the fruit flesh; P5 (BG 033) for 100-seed weight; and P6 for number of nodes per main vine. The SCA effect as well as reciprocal effect was also significant for most of the important characters in different crosses.

Resumo A análise da capacidade de combinação fornece informações úteis para a seleção dos pais, também informações sobre a natureza e a magnitude das ações dos genes envolvidos. A melhoria das safras envolve estratégias para aumentar a potencialidade da produção e os componentes de qualidade. Visando ao aprimoramento dos respectivos caracteres em cabaça-amarga, capacidade de combinação e parâmetros genéticos para 19 caracteres, foram estimados a partir de uma técnica de análise dialélica completa 6 × 6.

Indicou a importância das ações gênicas aditivas e não aditivas. As variâncias GCA foram maiores em magnitude do que as variâncias SCA para todos os caracteres estudados, indicando a predominância dos efeitos do gene aditivo em sua herança. O pai P2 (BG 009) apareceu como o melhor combinador geral para o início; P1 (BG 006) para número de frutos, peso médio de um único fruto e produção de frutos; P4 (BG 027) para número de nó da primeira flor fêmea e dias para a maturidade do fruto da semente; P3 (BG 011) para comprimento do fruto e espessura da polpa do fruto; P5 (BG 033) para peso de 100 sementes; e P6 para o número de nós por videira principal. O efeito SCA, bem como o efeito recíproco, também foi significativo para a maioria dos personagens importantes em cruzamentos diferentes.

Implementation through translation: a qualitative case study of translation processes in the implementation of quality improvement collaboratives.

BACKGROUND: Quality improvement collaboratives (QICs) are used extensively to implement quality improvement in healthcare, and current research is demonstrating positive yet varying evidence. To interpret the effectiveness results, it is necessary to illuminate the dynamics of QIC implementation in specific contexts. Using Scandinavian institutionalist translation theory as a theoretical framework, this study aims to make two contributions. First, we provide insights into the dynamics of the translation processes inherent in QIC implementation. Second, we discuss the implications of the translation processes as experienced by participating actors. METHODS: We used empirical data from a qualitative case study investigating the implementation of QICs as an approach to quality improvement within a national Danish healthcare quality program. We included two diverse QICs to allow for exploration of the significance of organizational complexity for the translation processes. Data comprised qualitative interviews, participant observation and documentary material. RESULTS: Translation was an inherent part of QIC implementation. Key actors at different organizational levels engaged in translation of their implementation roles, and the QIC content and methodology. They drew on different translation strategies and practices that mainly materialized as kinds of modification. The translations were motivated by deliberate, strategic, and pragmatic rationales, contingent on combinations of features of the actors' organizational contexts, and the transformability and organizational complexity of the QICs. The findings point to a transformative power of translation, as different translations led to various regional and local QIC versions. Furthermore, the findings indicate that translation affects the outcomes of the implementation process and the QIC intervention. Translation may positively affect the institutionalization of the QICs and the creation of professional engagement and negatively influence the QIC effects. CONCLUSION: The findings extends the current research concerning the understanding of the dynamics of the translation processes embedded in the local implementation of QICs, and thus constitute a valuable contribution to a more sustainable and effective implementation of QICs in healthcare improvement. For researchers and practitioners, this highlights translation as an embedded part of the QIC implementation process, and encourages detailed attention to the implications of translation for both organizational institutionalization and realisation of the expected intervention outcomes.

Increasing Inclusion, Diversity, Antiracism, and Equity With a Medical School Curriculum Quality Improvement Project.

ABSTRACT: The students at Mayo Clinic Alix School of Medicine (MCASOM) wrote a call to action to medical school leadership in June 2020. The students requested help in navigating socio-political barriers that affected one another and contributed to healthcare inequities and mistrust. Using the Association of American Medical Colleges (AAMC) tool to assess cultural competence training, our team evaluated the baseline 2017-2018 MCASOM curriculum. There were 254 learning objectives, of which 43 (17%) were related to inclusion, diversity, antiracism, and equity (I-DARE). Mirroring the concerns of the students, the findings identified minimal content about antiracism and inclusion. By applying DMAIC principles for quality and process improvement, we aimed to increase the number of taught learning objectives about I-DARE content for the first-year and second-year medical students by 100%, from 43 to 86 objectives, without adversely affecting student satisfaction and true attendance. To address the underlying causes, we launched a virtual, multisite I-DARE medical school course and doubled the number of I-DARE-taught learning objectives from 43 to 107 (149%), compared with the baseline. The program evaluation review revealed that the students were self-reflective and provided a spectrum of experiences regarding the I-DARE course.

Thirty-day outcomes for suboccipital decompression in adults with Chiari malformation type I: a frailty-driven perspective from the American College of Surgeons National Surgical Quality Improvement Program.

OBJECTIVE: When indicated, patients with symptomatic Chiari malformation type I (CM-I) may benefit from suboccipital decompression (SOD). Although SOD is considered a lower-risk neurosurgical procedure, preoperative risk assessment and careful surgical patient selection remain critical. The objectives of the present study were twofold: 1) describe 30-day SOD outcomes for CM patients with attention to the impact of preoperative frailty and 2) design a predictive model for the primary endpoint of nonhome discharge (NHD). METHODS: There were 1015 CM-I patients who underwent SOD in the 2011-2020 American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database, as specified by diagnostic and procedural codes (Current Procedural Terminology code 61343). Descriptive statistics were used to analyze total cohort baseline demographics, preoperative comorbidities, and postoperative outcomes within 30 days of surgery. Univariate cross-tabulation was used to compare baseline demographics and preoperative characteristics across the NHD and home discharge (HD) cohorts. Receiver operating characteristic (ROC) curve analysis was used to assess the discriminative ability of the revised Risk Analysis Index (RAI-rev) on NHD. RESULTS: The study cohort had a median age of 36 years, and 80.6% of patients were female. Race distribution was categorized as White (69.9%), Black (16.6%), and other groups (13.6%). The most common preoperative comorbidities were active smoking (24.4%), hypertension (19.2%), and diabetes mellitus (4.7%). The primary outcome of NHD occurred in 4.6% of patients (n = 47). Increasing frailty (measured by the RAI-rev) was associated with a stepwise increase in the rate of NHD: 2.3% for RAI-rev scores 0-10, 5.8% for RAI-rev scores 11-15, 7.6% for RAI-rev scores 16-20, 18.2% for RAI-rev scores 21-25, and 77.8% for RAI-rev scores ≥ 26 (p < 0.001). Other preoperative factors associated with NHD included older age, nonelective surgery, diabetes, hypertension, and elevated creatinine (all p < 0.01). The other most common 30-day complications included unplanned readmission (9.3%), unplanned reoperation (5.3%), return to the operating room (5.8%), Clavien-Dindo grade IV (life-threatening) (1.5%), organ space surgical site infection (SSI) (1.5%), superficial SSI (1.4%), and reoperation for a CSF leak (1.1%). Surgical mortality (within 30 days) was extremely rare (1/1015, 0.1%). ROC curve analysis demonstrated that RAI-rev predicted NHD with significant discriminatory accuracy among CM-I patients who received SOD treatment (C-statistic 0.731, 95% CI 0.648-0.814). CONCLUSIONS: This decade-long analysis of a multicenter surgical registry provides internationally representative, modern rates of 30-day outcomes after suboccipital decompression (with or without duraplasty) for adult CM-I patients. Preoperative frailty assessment with the RAI-rev may help identify higher-risk surgical candidates.

A Quality Improvement Initiative on Reducing Blood Culture Contamination in the Emergency Department.

INTRODUCTION: Contaminated blood cultures may have detrimental effects on patients, the organization, and antimicrobial stewardship. Patients in the emergency department may need blood cultures collected before antimicrobial therapy. Contaminated blood culture samples may contribute to prolonged hospital stay and also are associated with delayed or unnecessary antimicrobial therapy. This initiative aims to improve the emergency department's blood culture contamination rate that will eventually benefit the patients who will receive timely and proper antimicrobial therapy, and benefit the organization fiscally. METHODS: This quality improvement initiative used the Define-Measure-Analyze-Improve-Control (DMAIC) process. The organization targets blood culture contamination rate of ≤2.5%. Control charts were used to study how blood culture contamination rate changed over time. In 2018, a workgroup was formed to work on this initiative. Improved site disinfection using 2% Chlorhexidine gluconate cloth before the standard procedure of blood culture sample collection was initiated. Chi squared test of significance was used to compare blood culture contamination rates 6 months before and during feedback intervention as well as contamination rate from source of blood draw. RESULTS: Blood culture contamination rates 6 months before and during feedback intervention showed significant decrease (3.52% before intervention and 2.95% after intervention; P < .05). Contamination rates differed significantly based on the source of blood culture draw (7.64% via line, 3.05% via percutaneous venipuncture, and 4.53% via other; P < .01). DISCUSSION: Blood culture contamination rate continued to decrease with the use of a predisinfection process with 2% Chlorhexidine gluconate cloth before blood sample collection process. Practice improvement also was evident with effective feedback mechanism.

Creating a Business Case for Success.

Health care is a highly competitive environment where managers must compete for finite resources. The Centers for Medicare & Medicaid Services-directed reimbursement models such as value-based purchasing and pay-for-performance heavily focused on quality improvement and nursing excellence are having a major impact on financial reimbursement for health care services in the United States. As such, nurse leaders must function in a business-focused environment where decisions regarding resource allocation are driven by quantifiable data, the potential return on investment, and the organization's ability to provide quality patient care in an efficient manner. It is imperative for nurse leaders to recognize the financial impact of potential additional revenue streams, as well as avoidable costs. Nurse leaders must also be skilled at translating the return on investment for nursing-centric programs and initiatives, often hidden in anecdotal terms and cost avoidance rather than revenue generation, to ensure appropriate resource allocation and budgetary assumptions. This article uses a case study framed within the business case to review a structured approach to operationalizing nursing-centric programs and highlights key strategies for success.

Implementation Science for the Practice-Oriented Nurse Leader.

Senior nurse leaders are accountable for improving patient outcomes efficiently and cost-effectively. Nurse leaders often find heterogeneous patient outcomes across comparable nursing units in the same enterprise, presenting a challenge for nurse leaders tasked with making system-wide quality improvements. Implementation science (IS) offers a promising new approach to guide nurse leaders in understanding why certain implementation efforts meet with success or failure and the barriers faced in making practice changes. Knowledge of IS builds upon evidenced-based practice and quality improvement knowledge, adding to the armamentarium of tools at nurse leaders' disposal for improving nursing and patient outcomes. In this article, we demystify IS, differentiate it from evidence-based practice and quality improvement, describe IS concepts every nurse leader should be familiar with, and outline nurse leaders' role in building IS in their organizations.

Can a quality improvement intervention improve person-centred maternity care in Kenya?

Few evidence-based interventions exist to improve person-centred maternity care in low-resource settings. This study aimed to understand whether a quality improvement (QI) intervention could improve person-centred maternity care (PCMC) experiences for women delivering in public health facilities in Kenya. A pre-post design was used to examine changes in PCMC scores across three intervention and matched control facilities at baseline (n = 491) and endline (n = 677). A QI intervention, using the Model for Improvement, was implemented in three public health facilities in Nairobi and Kiambu Counties in Kenya. Difference-in-difference analyses using models that included main effects of both treatment group and survey round was conducted to understand the impact of the intervention on PCMC scores. Findings suggest that intervention facilities' average total PCMC score decreased by 5.3 points post-intervention compared to baseline (95% CI: -8.8, -1.9) and relative to control facilities, holding socio-demographic and facility variables constant. Additionally, the intervention was significantly associated with a 1.8-point decrease in clinical quality index pre-post-intervention (95% CI: -2.9, -0.7), decreased odds of provider visits, and less likelihood to plan to use postpartum family planning. While improving the quality of women's experiences during childbirth is a critical component to ensure comprehensive, high-quality maternity care experiences and outcomes, further research is required to understand which intervention methods may be most appropriate to improve PCMC in resource-constrained settings.

Quality Improvement in the Management of Subarachnoid Hemorrhage: Current State and Future Directions.

PURPOSE OF REVIEW: Aneurysmal subarachnoid hemorrhage carries high mortality and morbidity. Quality improvement (QI) efforts in the management of this disease process are growing as the field of neurocritical care matures. This review provides updates in QI in subarachnoid hemorrhage (SAH) and discusses gaps and future directions. RECENT FINDINGS: Literature published on the topic over the past 3 years were evaluated. An assessment of current QI practices pertaining to the acute care of SAH was conducted. These include processes surrounding acute pain management, inter-hospital coordination of care, complications during the initial hospital stay, role of palliative care, and quality metrics collection, reporting, and monitoring. SAH QI initiatives have shown promise by decreasing ICU and hospital lengths of stay, health care costs, and hospital complications. The review reveals substantial heterogeneity, variability, and limitations in SAH QI protocols, measures, and reporting. Uniformity in QI research, implementation, and monitoring will be crucial as disease-specific QI develops in neurological care.

The Opening of High-Speed Railways, the Improvement of Factor Allocation Efficiency between Regions, and the City's Environmental Quality Improvement.

Based on the panel data of prefecture-level cities in China from 2006 to 2019, this paper uses the PSM-DID method to empirically test the internal impact mechanism among high-speed railway opening, inter-regional factor allocation efficiency, and urban environmental governance. The research results show that: (1) There is a serious factor-misallocation problem among prefecture-level cities in China. From 2006 to 2019, the factor misallocation between prefecture-level cities led to an average annual loss of total factor productivity in China's economy of 52.5%, an average labor misallocation of 23.16%, and an average capital misallocation of 18.69%. Since 2013, capital misallocation has exceeded labor misallocation as the main reason for factor misallocation among prefecture-level cities in China. (2) The opening of high-speed railways can promote the efficiency of urban factor allocation through the technological innovation effect, the foreign investment attraction effect, and the population agglomeration effect. The improvement of urban factor allocation efficiency can promote the improvement of urban environmental quality through the effects of industrial structure optimization, income enhancement, and human capital agglomeration. Therefore, the opening of a high-speed railway can improve urban environmental quality through the intermediary effect of improving the efficiency of urban factor allocation; that is, the opening of a high-speed railway has a dual positive effect of economic efficiency and environmental quality improvement. (3) The optimization effect of factor allocation and the environmental governance effect of the opening of high-speed railways have strong urban scale heterogeneity, urban characteristic heterogeneity, and regional heterogeneity. The research content of this paper has important guiding significance for the construction of China's new development paradigm, accelerating the construction of "a unified national market," and green and low-carbon development.

Protocol for the Pathways Study: a realist evaluation of staff social ties and communication in the delivery of neonatal care in Kenya.

INTRODUCTION: The informal social ties that health workers form with their colleagues influence knowledge, skills and individual and group behaviours and norms in the workplace. However, improved understanding of these 'software' aspects of the workforce (eg, relationships, norms, power) have been neglected in health systems research. In Kenya, neonatal mortality has lagged despite reductions in other age groups under 5 years. A rich understanding of workforce social ties is likely to be valuable to inform behavioural change initiatives seeking to improve quality of neonatal healthcare.This study aims to better understand the relational components among health workers in Kenyan neonatal care areas, and how such understanding might inform the design and implementation of quality improvement interventions targeting health workers' behaviours. METHODS AND ANALYSIS: We will collect data in two phases. In phase 1, we will conduct non-participant observation of hospital staff during patient care and hospital meetings, a social network questionnaire with staff, in-depth interviews, key informant interviews and focus group discussions at two large public hospitals in Kenya. Data will be collected purposively and analysed using realist evaluation, interim analyses including thematic analysis of qualitative data and quantitative analysis of social network metrics. In phase 2, a stakeholder workshop will be held to discuss and refine phase one findings.Study findings will help refine an evolving programme theory with recommendations used to develop theory-informed interventions targeted at enhancing quality improvement efforts in Kenyan hospitals. ETHICS AND DISSEMINATION: The study has been approved by Kenya Medical Research Institute (KEMRI/SERU/CGMR-C/241/4374) and Oxford Tropical Research Ethics Committee (OxTREC 519-22). Research findings will be shared with the sites, and disseminated in seminars, conferences and published in open-access scientific journals.

Reducing incidence of postoperative acute kidney injury in trauma and orthopaedics patients: a quality improvement project.

BACKGROUND: Acute kidney injury (AKI) is a common postoperative complication which increases morbidity and mortality. This quality improvement project aimed to implement measures targeting known risk factors to decrease the incidence of postoperative AKI in trauma and orthopaedics (T&O) patients. METHODS: Data were collected across three six-month to 7-month cycles between 2017 and 2020, analysing all elective and emergency T&O operated patients within a single NHS Trust (n=714, 1008 and 928, respectively). Patients who developed a postoperative AKI were identified using biochemical criteria and data were collected on known AKI risk factors, including use of nephrotoxic medications, and patient outcomes. In the final cycle, the same variables were collected for patients without AKI. Between cycles, measures implemented included: preoperative and postoperative medication reconciliation aiming to stop nephrotoxic medications, orthogeriatrician review of high-risk patients and junior doctor teaching on fluid therapy. Statistical analysis was undertaken to determine the incidence of postoperative AKI across cycles, prevalence of risk factors and impact on length of hospital stay and postoperative mortality. RESULTS: There was a statistically significant decrease in postoperative AKI incidence from 4.27% (43 of 1008 patients) in cycle 2 to 2.05% (19 of 928) in cycle 3 (p=0.006), with a notable decrease in use of nephrotoxic medications. Significant predictors for the development of postoperative AKI included use of diuretics and receiving multiple nephrotoxic drug classes. Development of postoperative AKI significantly increased length of hospital stay by 7.11 days on average (95% CI: 4.84 to 9.38 days, p<0.001) and risk of 1-year postoperative mortality (OR 3.22, 95% CI: 1.03 to 10.55, p=0.046). CONCLUSION: This project demonstrates that a multifaceted approach targeting modifiable risk factors can reduce incidence of postoperative AKI in T&O patients, which may lead to reduced length of hospital stay and postoperative mortality.

Patient-reported outcome and experience measures for quality improvement in pregnancy and childbirth care: a retrospective cohort study.

BACKGROUND: Patient-reported outcome measures (PROMs) and patient-reported experience measures (PREMs) can highlight issues that remain unnoticed when using standard clinical quality indicators. However, estimations of the potential power of measuring PROMs and PREMs to identify unrecognised areas suitable for quality improvement are often limited by a lack of reliable real-world data. Here, we report on how the indicator set for PROMs and PREMs that was recently developed by the International Consortium for Health Outcome Measures can change perspectives on quality assessment in women receiving care for pregnancy and childbirth. METHODS: PROMs and PREMs were captured 6 months after childbirth via an online survey in a single academic maternity unit in the Netherlands between 2018 and 2019. Indicators of abnormality were scored using predefined cut-off values established by a national consensus group. We used regression analysis to identify associations between PROMs, PREMs and healthcare use, and further stratified data to explore the distribution of indicators among relevant patient subgroups. RESULTS: Of 2775 questionnaires, 645 were completed and linked to medical health records. Despite only 5% of women reporting overall dissatisfaction with care, suboptimal scores were often found; in birth experience for 32% of the population, and 42% who experienced painful sexual intercourse. Subgroup analysis further revealed associations with relevant indicators of quality of care; inadequate pain relief among women with preterm birth (OR 8.8), pain with sexual intercourse among women undergoing vaginal assisted delivery (OR 2.2) and women living in a deprived area had problematic birth experiences (coefficient -3.2). CONCLUSION: Use of PROMs and PREMs in pregnancy and childbirth care provides new insights on quality of care, resulting in potentially actionable targets for improvement not normally identified with standard clinical quality indicators. Implementation strategies and follow-up are needed to act on these findings.

Study on coffee quality improvement by self-induced anaerobic fermentation: Microbial diversity and enzymatic activity.

The postharvest fermentation process of coffee has rapidly advanced in the last few years due to the search for quality and diversity of sensorial profiles. A new type of fermentation, named self-induced-anaerobic fermentation (SIAF), is a promising process that has been increasingly used. This study aims to evaluate the sensorial improvement of coffee beverages during SIAF and the influence of microorganism's community and enzymatic activity. The SIAF process was conducted in Brazilian farms for up to 8 days. The sensorial quality of coffee was evaluated by Q-graders; the microbial community was identified by the high-throughput sequencing of 16S rRNA and ITS regions; and the enzymatic activity (invertase, polygalacturonase, and endo-ß-mannanase) was also investigated. SIAF increased up to 3.8 points in the total score of sensorial evaluation (compared to the non-fermented sample), in addition to presenting more flavor diversity (especially within the fruity and sweetness descriptors). The high-throughput sequencing identified 655 bacterial and 296 fungal species during the three processes. The bacteria Enterobacter sp., Lactobacillus sp., Pantoea sp., and the fungi Cladosporium sp. and Candida sp. were the predominant genera. Fungi that are potential producers of mycotoxin were identified throughout the process, which indicates a risk of contamination since some of them are not degraded in the roasting process. Thirty-one species of microorganisms were described for the first time in coffee fermentation. The microbial community was influenced by the place where the process was carried out, mainly in relation to the diversity of fungi. Washing the coffee fruits before fermenting led to a fast reduction of pH; a fast development of Lactobacillus sp. and a fast dominance of Candida sp.; a reduction of the fermentation time necessary to achieve the best sensorial score; an increase in the invertase activity in the seed; a more expressive invertase activity in the husk; and a decreasing trend in polygalacturonase activity in the coffee husk. The increase in endo-ß-mannanase activity suggests that coffee starts germinating during the process. SIAF has a huge potential to increase the quality and add value to coffee, but further studies must be conducted to access its safety. The study allowed a better knowledge of the spontaneous microbial community and the enzymes that were present in the fermentation process.

Perceptions of an Interactive Trauma Recovery Information Booklet.

BACKGROUND: Previous research has shown that people with traumatic injuries have unmet information needs with respect to their injuries, management, and recovery. An interactive trauma recovery information booklet was developed and implemented to address these information needs at a major trauma center in Victoria, Australia. OBJECTIVE: The aim of this quality improvement project was to explore patient and clinician perceptions of a recovery information booklet introduced into a trauma ward. METHODS: Semistructured interviews with trauma patients, family members, and health professionals were undertaken and thematically analyzed using a framework approach. In total, 34 patients, 10 family members, and 26 health professionals were interviewed. RESULTS: Overall, the booklet was well accepted by most participants and was perceived to contain useful information. The design, content, pictures, and readability were all positively appraised. Many participants used the booklet to record personalized information and to ask health professionals questions about their injuries and management. CONCLUSION: Our findings highlight the usefulness and acceptability of a low-cost interactive booklet intervention to facilitate the provision of quality of information and patient-health professional interactions on a trauma ward.
