Post-operative morbidity after neoadjuvant chemotherapy and resection for gallbladder cancer: A national surgical quality improvement program analysis

BACKGROUND Gallbladder cancer is the most common malignancy of the biliary tract.Neo-adjuvant chemotherapy(NACT)has improved overall survival by enabling R0 resection.Currently,there is no consensus of guidelines for neoadjuvant therapy in gallbladder cancer.As investigations continue to analyze the regimen and benefit of NACT for ongoing care of gallbladder cancer patients,we examined American College of Surgeons National Surgical Quality Improvement Program(NSQIP)database to determine if there was higher morbidity among the neo-adjuvant group within the 30-day post-operative period.We hypothesized patients who underwent NACT were more likely to have higher post-operative morbidity.AIM To investigate the 30-day post-operative morbidity outcomes between patients who received NACT and underwent surgery and patients who only had surgery.METHODS A retrospective analysis of the targeted hepatectomy NSQIP data between 2015 and 2019 was performed to determine if NACT in gallbladder cancer increased the risk for post-operative morbidity(bile leak,infection rate,rate of converting to open surgery,etc.)compared to the group who only had surgery.To calculate the odds ratio for the primary and secondary outcomes,a crude logistic regression was performed.RESULTS Of the 452 patients,52 patients received NACT prior to surgery.There were no statistically significant differences in the odds of morbidity between the two groups,including bile leak[odds ratio(OR),0.69;95%confidence interval(95%CI):0.16-2.10;P=0.55],superficial wound infection(OR,0.58;95%CI:0.03-3.02;P=0.61),and organ space wound infection(OR,0.63;95%CI:0.18-1.63;P=0.61).CONCLUSION There was no significant difference in the risk of 30-day post-operative morbidity between the NACT and surgery group and the surgery only group.

Research on the Construction and Quality Improvement of Art Curriculum in Rural Primary Schools

Curriculum quality is the foundation of education development and the core element of primary education and teaching.It is a key indicator to measure and evaluate the level of educational development in a country and region.Curriculum quality needs to be examined not only from the perspective of the degree of achievement of the preset curriculum goals,but also from the perspective of students’subjective feelings and experiences.Art course is the core service provided by the school for students,and the quality of the course is judged by the acquisition and development of students.At the same time,the value of aesthetic education also calls for the reform and improvement of the fine arts curriculum,which requires the fine arts curriculum in all stages in rural areas to get closer and change in this direction.After the promulgation of art curriculum standards,the fine arts curriculum of rural primary schools should follow high quality standards,which is a process of optimization and iteration of various elements of primary art curriculum.The fine arts curriculum of rural primary schools needs to meet the exploration needs of current students,effectively and appropriately develop excellent local resources while enriching the curriculum content,introduce the essence of regional culture and art,improve the evaluation of curriculum quality,and form a scientific curriculum management system,so as to promote the sustainable development of students.According to this understanding,we can improve the quality of art curriculum in rural primary schools from four dimensions:curriculum objectives,curriculum content,curriculum implementation,and curriculum evaluation.

Impact of pre- and peri-operative risk factors on length of stay and hospital readmission following minimally-invasive partial nephrectomy

Objective:We conducted an analysis of the American College of Surgeons National Surgical Quality Improvement Program database for minimally-invasive partial nephrectomy cases reported with the goal to identify pre-and peri-operative variables associated with length of stay(LOS)greater than 3 days and readmission within 30 days.Methods:Records from 2008 to 2018 for“laparoscopy,surgical;partial nephrectomy”for prolonged LOS and readmission cohorts were compiled.Univariate analysis with Chi-square,t-tests,and multivariable logistic regression analysis with odds ratios(ORs),p-values,and 95%confidence intervals assessed statistical associations.Results:Totally,20306 records for LOS greater than 3 days and 15854 for readmission within 30 days were available.Univariate and multivariable analysis exhibited similar results.For LOS greater than 3 days,undergoing non-elective surgery(OR=5.247),transfusion of greater than four units within 72 h prior to surgery(OR=5.072),pre-operative renal failure or dialysis(OR=2.941),and poor pre-operative functional status(OR=2.540)exhibited the strongest statistically significant associations.For hospital readmission within 30 days,loss in body weight greater than 10%in 6 months prior to surgery(OR=2.227)and bleeding disorders(OR=2.081)exhibited strongest statistically significant associations.Conclusion:Multiple pre-and peri-operative risk factors are independently associated with prolonged LOS and hospital readmission within 30 days of surgery using the American College of Surgeons National Surgical Quality Improvement Program data.Recognizing the risks factors that can potentially be improved prior to minimally-invasive partial nephrectomy is crucial to informing patient selection,optimization strategies,and patient education.

Performance of a Horizontal Flow Constructed Reed Bed Filter for Municipal Wastewater Treatment: The Case Study of the Prototype Installed at Gaston Berger University, Saint-Louis, Senegal

In Saint-Louis, Senegal, a constructed wetland with horizontal flow reed beds (FHa and FHb) has demonstrated significant efficacy in treating municipal wastewater. Analyzing various treatment stages, the system showed only a slight temperature variation, from an influent average of 26.3°C to an effluent of 24.7°C. Electrical conductivity decreased from 1331 mS/cm to 974.5 mS/cm post-primary treatment, with suspended solids (SS) dramatically reduced from 718.9 mg/L to 5.7 mg/L in the final effluent. Biochemical oxygen demand (BOD5) and chemical oxygen demand (COD) saw a notable decrease, from initial levels of 655.6 mg/L and 1240 mg/L to 2.3 mg/L and 71.3 mg/L, respectively. Nitrogenous compounds (N-TN) and phosphates () also decreased significantly, indicating the system’s nutrient removal capacity. Microbiological analysis revealed a reduction in fecal coliforms from 7.5 Ulog/100ml to 1.8 Ulog/100ml and a complete elimination of helminth eggs. The presence of Phragmites and Typha was instrumental in enhancing these reductions. The system’s compliance with the Senegalese standards for disposal into natural environments, WHO recommendations for unrestricted water reuse in irrigation, and the European legislation for water reuse was established. The effluent quality met the stringent criteria for various classes of agricultural reuse, illustrating the system’s potential for sustainable water management. This wetland model presents a robust solution for water-stressed regions, ensuring environmental protection while supporting agricultural needs. The study calls for ongoing research to further refine the system for optimal, reliable wastewater treatment and water resource sustainability.

Phytosynthetic bacteria (PSB) as a water quality improvement mechanism in saline-alkali wetland ponds

The efficiency of phytosynthetic bacteria (PSB) to improve the water quality in saline alkali ponds was studied, the result showed that (1) PSB application could increase the content of DO, NO\+-\-3\|N and effective phosphorus (EP) in ponds; (2) the changes of COD were not evident, just effective in later period after PSB application; (3) PSB application could decrease the contents of NH\+-\-4\|N (NH\-3\|N), NO\+-\-2\|N ; (4) PSB application could improve the structure of the effective nitrogen (EN) and EP, stimulate the growth of phytoplankton, and increase primary productivity, and finally increase the commercial profits of ponds because of the increase of EP and the decrease of EN contents; (5) the effect exerting speed of PSB was slower, but the effect sustaining time was longer; (6) the appropriate concentration of PSB application in saline alkali wetland ponds was 10×10 -6 mg/L, one time effective period was more than 15 days. So PSB was an efficient water quality improver in saline alkali ponds.

Targeted mutagenesis of amino acid transporter genes for rice quality improvement using the CRISPR/Cas9 system

High grain protein content(GPC) reduces rice eating and cooking quality(ECQ). We generated OsAAP6 and OsAAP10 knockout mutants in three high-yielding japonica varieties and one japonica line using the CRISPR/Cas9 system. Mutation efficiency varied with genetic background in the T_0 generation, and GPC in the T_1 generation decreased significantly,owing mainly to a reduction in glutelin content. Amylose content was down-regulated significantly in some Osaap6 and all Osaap10 mutants. The increased taste value of these mutants was supported by Rapid Visco Analysis(RVA) profiles, which showed higher peak viscosity and breakdown viscosity and lower setback viscosity than the wild type. There were no significant deficiencies in agronomic traits of the mutants. Targeted mutagenesis of OsAAP6 and OsAAP10, especially OsAAP10, using the CRISPR/Cas9 system can rapidly reduce GPC and improve ECQ of rice, providing a new strategy for the breeding cultivars with desired ECQ.

Discussion on strategy of grain quality improvement for super high yielding japonica rice in Northeast China

japonica rice is mainly distributed in Northeast China and accounts for 44.6% of the total cultivated area of japonica rice in China. The comprehensive using of inter-subspecies heterosis is the main breeding mode of super japonica rice varieties in this region. Improving rice quality at relative high yielding level is the current research focus. Performing crosses between indica and japonica lines allows for the recombination of regulatory genes and genetic backgrounds, leading to complicated genetic rice quality characteristics, which can be used to explore patterns of quality improvement. In the present study, we utilize recombinant inbred lines （RILs） derived from indica-japonica hybridization to analyze the effect factors of rice quality derived from genetic factors, which contain both regulatory genes concerning rice quality and genetic backgrounds＇ random introduction frequency coming from indica （Di value）, and the improvement strategy was further discussed. The regulatory genes involved in amylase content （Wx） and nitrogen utilization efficiency （NRT1.1B） were the major factors affecting the amylose content （AC） and protein content （PC） in RILs, respectively. Both the Di value and the major grain width gene （GS5） had regulatory effects on milled rice width （MRW） in RILs, and their interaction explained the major variance of MRW in the RILs. With the mediation of MRW and chalkiness degree （C）, Di value had a further impact on head rice rate （HR）, which was relatively poor when the Di value was over 40%. In Northeast China, the Di value should be lowered by backcrossing or multiple crosses during the breeding of indica-japonica hybridization to maintain the whole better HR and further to emphasize the use of favorable genes in individual selection.

Purpose:Patients'complaints can be predictors of patient care quality and safety.Understanding patients'complaints could help healthcare organizations target the areas for improvements.The purpose of this study is to use a mixed method analysis to a)examine the characteristics and categories of patients'complaints,b)explore the relationships of patients'complaints with professions and units,and c)propose theory-based strategies to improve care quality.Methods:This is a descriptive mixed method study.Data examined are patients'complaints filed at a university-affiliated hospital in China from January 2016 to December 2017.A qualitative content analysis was conducted to categorize complaints.A TwoStep cluster analysis was performed to provide an overall profile of patients'complaints.Chi-Square tests were conducted to investigate the relationships among complaints,professions,and units.Results:838 complaints were filed,with 821 valid cases for analysis.Six categories surfaced from the qualitative analysis:uncaring attitudes,unsatisfactory quality of treatment or competence,communication problems,the process of care,fees and billing issues,and other miscellaneous causes.Physicians received most of the complaints(56.6%).The unit receiving the most complaints were outpatient clinics and medical support units(52.7%).The cluster analysis indicated four distinct clusters.Significant relationships existed between complaints and professions(x2(20)=178.82,P<0.01),and between complaints and units(x2(15)=42.72,P<0.01).Conclusions:Patients'complaints are valuable sources for quality improvements.Healthcare providers should be not only scientifically knowledgeable,but also humanistic caring.Caring-based theories may provide guidance in clinical practice.

A healthcare quality management system underpinning the 3-E model and its application in a new tertiary hospital in Australia

Objectives: Engaging, enhancing and embedding clinical audit improvement activities into everyday practice to develop capacity, capability and culture in continuous improvement.Method: Through the implementation of an electronic quality management system called Governance, Evidence, Knowledge and Outcome (GEKO), the key aspects of governance, evidence knowledge and outcomes were able to be applied to quality initiatives. Implementation of the GEKO system incorporated the principles of total quality control and management to include strategic management control and marketing in parallel with leadership strategies. The vision was to motivate staff to enable ownership of the quality cycle of continuous improvement of patient care to incorporate underlying systems and processes that impact on patient care. Results: A continuous improvement pathway was successfully established 4 months post hospital commissioning. Over 890 (approximately 16% workforce) multidisciplinary and multi-professional staff received training and support for QIs in 12 months;over 535 quality proposals were received on GEKO. Submissions by profession: nursing and midwifery 46% (246), medical 33%(177), allied health 9% (48), pharmacy 5%(27), and non-clinical staff 7%(37). Average new submissions per month were 42. Reviews demonstrated the application of a rapid cycle approach to develop, test, modify and refine improvements and enhanced clinical care. Conclusion: Appropriate governance structure, processes, extensive education and training together with collaborative relationships are the keys to embed clinical audit improvement into everyday practice. The availability of a quality management system like GEKO is very useful to make QI accessible to all staff.

Study on Quality Improvement Effect and Separate Character of Soybean Male Sterile (MS1) Recurrent Selection Population

To solve the problem that soybean has narrow genetic base, we constructed a series of male sterile recurrent selection populations, and studied the effects of quality improvement and practical value. An LD-base population, which fits to our ecology type was constructed by 6 years＇ gene enrichment through the introduction of new genes from 23 local varieties and recurrent selection. The LD-base populations were then improved by making crosses with high protein and high oil genotypes. As a result we obtained a high protein sub-population （db） and a high oil sub-population （gy）, For the db sub-population, the protein content is 1.18% higher than the base population, 22.38% of the individuals contain 45% or more of protein, which is 10.99% higher than the base population. For the gy sub-population, oil content is 0.24% higher than the base population. Individuals with oil content of 20% or more are 11.05% higher than the base population. The quantitative characters such as flowering date, mature date, pod habit, and hilum color, etc., all showed wide range of separation, and the segregation ratio approached balance. The c.v. of branch number of ms1 recurrent population （72.8%） is higher than general cross-population （57.3%）, and the c.v. of 100 seed weight of ms1 （18.1%） is higher than general cross population （16.5%）, the coefficient of variation of plant height, pods per plant, and seeds per pod were not significantly different. It was demonstrated in this paper that the quality character of ms 1 male sterile recurrent selection population was improved by adding new genes. And the segregation of other characters widened, making the populations suitable for the objective of soybean breeding. In this paper, we also discussed the breeding method, key technology, and selection effect of soybean ms 1 population.

Developing an evidence-based and theory informed intervention to involve families in patients care after surgery: A quality improvement project

Objectives: In the post-surgical setting,active involvement of family caregivers has the potential to improve patient outcomes by prevention of surgical complications that are sensitive to fundamental care.This paper describes the development of a theoretically grounded program to enhance the active involvement of family caregivers in fundamental care for post-surgical patients.Methods: We used a quality improvement project following a multi-phase design.In Phase 1,an iterative method was used to combine evidence from a narrative review and professionals' preferences.In Phase 2,the logic model underlying the program was developed guided by four steps: (1) confirm situation,intervention aim,and target population;(2) documented expected outcomes,and outputs of the intervention;(3) identify and describe assumptions,external factors and inputs;and (4) confirm intervention components.Results: Phase 1 identified a minimum set of family involvement activities that were both supported by staff and the narrative review.In Phase 2,the logic model was developed and includes (1) the inputs (e.g.educational-and environmental support),(2) the ultimate outcomes (e.g.reduction of postoperative complications),(3) the intermediate outcomes (e.g.behavioural changes),and (4) immediate outcomes (e.g.improved knowledge,skills and attitude).Conclusions: We demonstrated how we aimed to change our practice to an environment in which family caregivers were stimulated to be actively involved in postoperative care on surgical wards,and how we took different factors into account.The description of this program may provide a solid basis for professionals to implement the family involvement program in their own setting.

Interventions to Improve HIV Viral Load Suppression among the Adolescents: Evidence of Improvement Science through a Quality Improvement Approach in Eastern Uganda

Introduction: Achieving viral load suppression among the adolescents living with HIV continues to hold back attainment of sustainable development goals. TASO Mbale realized a viral load suppression rate of 63.1% among the adolescents living with HIV in care in quarter 4 of 2016. We therefore, instituted a quality imrpovement project to improve Viral load suppression from 63.1% in quarter 4 2016 to 90% by the end of quarter 4 2017. Method: Baseline data from the Uganda viral load dashboard were analyzed, and fishbone diagram was utilized to provide root causes of low viral load suppression among the adolescents living with HIV at TASO Mbale. The identified barriers were Knowlegde gap, among the adolescents, on positive living, Missing clinic appointments, Sub-optimal adherence, Poorly planned adolescent HIV clinic, Inadequate follow-up and Low use of data for informed decisions. A plan-do-study-act (PDSA) model was applied to implement tested changes. Strategies that worked included introduction of appointment register to track appointment behaviour of the adolescents, generating lists of clients on appointment who were due for Viral Load bleeding, telephone calls for follow up, increasing the frequency of reviewing adolescents from once a month to twice a week, committing a dedicated team responsible for adolescent care. Results: The viral load suppression improved from 63.1% in quarter 4 of 2016 to 63.8% in the first quarter of 2017, to 87.5% in quarter 2 of 2017, 97.6% in the third quarter and 91.4% in quarter 4 of 2017. Conclusion: The use of quality improvement in addressing gaps in HIV service delivery is highly effective.

CONTINUOUS IMPROVEMENT THROUGH INTEGRATION OF QUALITY TOOLS

The relationship between major quality tools such as quality function development （QFD）, failure mode and effects analysis （FMEA）, design of experiments （DOE） and statistical process control （SPC） is analyzed through an extensive review of the literature and the concurrent quality engineering philosophy, and a basic structure for the integration of quality tools is presented. An integrated quality management system （IQMS） is developed using C＋＋ Builder, running in the Windows 2000 Server environment with the basic internet connections, and SQL Server 2000 as the platform for developing the database, An illustrative example applying IQMS to the continuous quality improvement for a crane equipment manufacturing is reported. The result shows that the application of IQMS can optimize the process of design and manufacturing, shorten the cycle time of product, reduce the cost, and realize quality improvement continuously, The proposed integrated framework with IOMS is believed to be applicable to continuous quality improvement in many manufacturing companies.

A Retrospective Quality Study of Hemodialysis Catheter-Related Bacteremia in a Danish Hospital

Background: Hemodialysis catheter-related bacteremia (HD CRB) is a major complication of long-term hemodialysis (HD) therapy and bacteremia is secondary only to cardiovascular disease as the leading cause of death in patients receiving renal replacement therapy. A large part may be preventable and surveillance is a critical aspect of infection control and prevention. Aim: To analyze incidence, causative species, and treatment of HD CRB in adult chronic HD patients at Nordsjaellands Hospital (NOH), Denmark. Methods: All episodes of bacteremia in the Department of Cardiology, Nephrology and Endocrinology (KNEA), NOH from 2010 to 2013 were analyzed. Inclusion criteria: Adult chronic HD patients with a tunneled dialysis catheter diagnosed with HD CRB. Causative microorganism and antimicrobial treatment were recorded for each episode. Findings: Ninetynine episodes of HD CRB in 72 patients were found with a mean incidence rate of 0.9/1000 catheter-days. Gram-positive bacteria were isolated in 71% of the episodes, gram-negative bacteria in 25%, both in 3%, and yeast in 1%. The most frequently isolated microorganisms were Staphylococcus aureus (33%), Coagulase-negative staphylococci (29%), enterobacteriaceae (20%) and enterococci (8%). The most commonly used empiric antimicrobials were cefuroxime and vancomycin and the overall efficacy was 77%. Conclusion: The well-functioning infection prevention strategy seems to be successful resulting in a relatively low incidence rate of HD CRB compared with that shown in international studies. The high proportion of gram-negative bacteria raises the question as to whether future antimicrobial guidelines should cover both gram-positive and gram-negative bacteria.

Using Target Ablation for Ion Beam Quality Improvement

During the laser foil interaction, the output ion beam quality including the energy spread and beam divergence can be improved by the target ablation, due to the direct laser acceleration （DLA） electrons generated in tile ablation plasma. The acceleration field established at the target rear by these electrons, which is highly directional and triangle-envelope, is helpful for the beam quality. With the help of the target ablation, both the beam divergence and energy spread will be reduced. If the ablation is more sufficient, the impact of DLA-electron-caused field will be strengthened, and the beam quality will be better, confirmed by the particle-in-cell simulation.

RNA interference targeting ω-secalin genes differentially affects the processing quality in a wheat T1BL·1RS translocation line

Wheat-rye T1BL·1RS translocation lines are widely used,especially in China,but their processing quality is generally poor.An interfering expression vector targeting theω-secalin genes was constructed with the 1Bx7 seed-specific promoter.Biolistic-mediated genetic transformation of the wheat cultivar KN199 carrying the T1BL·1RS translocation generated 10 transgenic lines.Two representative transgenic lines,8-2 and 13-7,were selected for analysis.Compared with the control,the two transformants showed an up to 4.5-fold decrease in totalω-secalins and various levels of decrease inω-gliadins,γ-gliadins,and low-molecular-weight glutenins.A decrease in high molecular weight(HMW)glutenin 1Bx7 was detected only in 8-2,owing possibly to promoter methylation.Increased levels ofα-gliadins were observed in both transformants,but increased levels of HMW glutenins were observed only in 13-7.Line 13-7 showed increases in gluten index,Zeleny sedimentation value,stabilization time,and maximum resistance.Its bread volume was 849.6 mL,an 11.9%increase over that of the control.Line 8-2 showed decreases in these parameters,but its total cake-making quality score was 88,an 17.3%increase over that of the control.The study demonstrates that the same RNAi construct may produce different effects on wheat processing quality and highlights the influence of the vector promoter in RNA interference.
