RESUMO
Quality improvement is a methodology which was initially developed and employed in the field of industrial manufacturing. This approach involves implementing a series of interventions aimed at elevating the existing quality standards to a higher level. In daily medical work, there are often spontaneous quality improvements. Medical quality improvements supported by scientific methodology can evaluate medical quality more scientifically and provide objective feedback on the quality of medical work for healthcare professionals. This article provides a concise introduction to quality improvement and shows its application and significance in the field of clinical medicine through examples.

OBJECTIVES: To develop effective measures to reduce antibiotic use duration in very low birth weight (VLBW) preterm infants in the neonatal intensive care unit through quality improvement methods. METHODS: The study population consisted of hospitalized VLBW preterm infants, with the percentage of hospitalization time during which antibiotics were used from November 2020 to June 2021 serving as the baseline. The specific quality improvement goal was to reduce the duration of antibiotic use. Factors affecting antibiotic use duration in preterm infants were analyzed using Pareto charts. Key drivers were identified, and specific interventions were formulated based on the stages of antibiotic use. Changes in the percentage of antibiotic use duration were monitored with run charts until the quality improvement target was achieved. RESULTS: From November 2020 to June 2021, the baseline antibiotic use duration percentage was 49%, with a quality improvement target to reduce this by 10% within 12 months. The Pareto analysis indicated that major factors influencing antibiotic duration included non-standard antibiotic use; delayed cessation of antibiotics when no infection evidence was present; prolonged central venous catheter placement; insufficient application of kangaroo care; and delayed progress in enteral nutrition. The interventions implemented included: (1) establishing sepsis evaluation and management standards; (2) educating medical staff on the rational use of antibiotics for preterm infants; (3) supervising the enforcement of antibiotic use standards during ward rounds; (4) for those without clear signs of infection and with negative blood cultures, discontinued the use of antibiotics 36 hours after initiation; (5) reducing the duration of central venous catheterization and parenteral nutrition to lower the risk of infection in preterm infants. The control chart showed that with continuous implementation of interventions, the percentage of antibiotic use duration was reduced from 49% to 32%, a statistically significant decrease. CONCLUSIONS: The application of quality improvement tools based on statistical principles and process control may significantly reduce the antibiotic use duration in VLBW preterm infants.

BACKGROUND: The role of macrophages in the pathogenesis of nonalcoholic steatohepatitis (NASH) is complex and unclear. METHODS: Single-cell RNA sequencing was performed on nonparenchymal cells isolated from NASH and control mice. The expression of Vsig4+ macrophages was verified by qPCR, flow cytometry and immunohistochemistry. Primary hepatic macrophages were cocultured with primary hepatocytes or hepatic stellate cells (LX2) cells by Transwell to detect immunofluorescence and oil red O staining. RESULTS: Two main single macrophage subsets were identified that exhibited a significant change in cell percentage when NASH occurred: resident Kupffer cells (KCs; Cluster 2) and lipid-associated macrophages (LAMs; Cluster 13). Nearly 82% of resident single KCs in Cluster 2 specifically expressed Cd163, and an inhibited subgroup of Cd163+ resident single-KCs was suggested to be protective against NASH. Similar to Cd163, Vsig4 was both enriched in and specific to Cluster 2. The percentage of Vsig4+-KCs was significantly decreased in NASH in vivo and in vitro. Hepatocytes and hepatic stellate cells produced less lipid droplet accumulation, proinflammatory protein (TNF-α) and profibrotic protein (α-SMA) in response to coculture with Vsig4+-KCs than in those cocultured with lipotoxic KCs. CONCLUSIONS: A subgroup of Vsig4+ resident single-KCs was shown to improve hepatic inflammation and fibrosis in NASH.

OBJECTIVE: To investigate the effects of family dignity intervention (FDI) on anxiety, depression, hope level and quality of life (QOL) of male infertility patients and their spouses. METHODS: Using quasi-experimental design, we selected male infertility patients and their spouses undergoing human-assisted reproductive technology (ART) in our Center of Reproductive Medicine from June to December 2022 and divided them into an intervention group (38 couples) and a control group (40 couples). The former underwent a four-stage FDI, including ovulation promotion cycle assessment, family sharing, pre-transplantation interview and post-transplantation follow-up, while the latter received routine nursing. Using Hospital Anxiety and Depression Scale, Herth Hope Index and Fertility Quality of Life Scale, we evaluated the effects of FDI before and after transplantation. RESULTS: After FDI, the anxiety and depression scores were significantly lower (P < 0.05) and the total scores on the hope level and all other dimensions remarkably higher in the intervention group than in the control (P < 0.05). The self-confidence of the couples in the intervention groups in ART treatment was markedly increased in comparison with that of the controls, and their scores on physical and mental health were significantly higher than those of the latter (P < 0.05). CONCLUSION: FDI can effectively relieve the anxiety and depression, raise the hope level and improve the quality of life of both male infertility patients and their spouses.

OBJECTIVES: To explore the characteristics of immune function of healthy full-term infants at the age of 3 months, and to analyze the relationship of immune function with feeding pattern and sex. METHODS: A total of 84 healthy full-term infants born in four hospitals in Beijing and Hohhot, China were prospectively recruited. Their feeding patterns remained unchanged within 4 months after birth. They were divided into a breast-feeding group and a milk powder feeding group according to their feeding patterns. At the age of 3 months after birth, peripheral venous blood samples of the two groups were collected to evaluate cellular immunity and humoral immunity and perform routine blood test. The laboratory indices were compared between infants with different feeding patterns and sexes. RESULTS: Compared with the milk powder feeding group, the breast-feeding group had significantly lower proportion of T cell second signal receptor CD28, immunoglobulin M, and proportion and absolute count of neutrophils (P<0.05) and significantly higher expression and proportion of HLA-DR, a surface activation marker of CD8+ T cells, and proportion of lymphocytes (P<0.05). The male infants had a significantly lower white blood cell count and a significantly higher proportion of eosinophils compared with the female infants (P<0.05). CONCLUSIONS: Sex has no significant effect on the proportion of lymphocyte subsets in 3-month-old full-term infants, but feeding patterns are associated with the proportion of CD28+ T cells (lymphocyte functional subset) and HLA-DR+ T cells (lymphocyte activation subset), suggesting that feeding patterns have a certain effect on the development of immune function in 3-month-old full-term infants.

OBJECTIVE: To summarize the extraintestinal manifestations and intestinal complications in children with Crohn's disease (CD). METHODS: The clinical data of 54 children who were diagnosed with CD in Peking Union Medical College Hospital from January 2008 to December 2018 were collected for retrospective analysis of extraintestinal manifestations and intestinal complications. According to the location of the lesion, the children were divided into ileocolonic group (30 cases), colonic group (6 cases), and ileal group (18 cases). RESULTS: In the 54 children, the mean age at diagnosis was 14.5±2.7 years, and the median duration from disease onset to definite diagnosis was 20 months (range: 1-36 months). Twenty-four patients (44%) had extraintestinal manifestations, with the two most common manifestations being growth retardation (11 cases, 20%) and oral mucosal ulcer (10 cases, 19%), followed by arthritis (2 cases, 4%), erythema nodosum (2 cases, 4%), and cholecystitis (2 cases, 4%). There were no significant differences in the incidence of extraintestinal manifestations among the three groups (P=0.792). The most common intestinal complications were anal fistula/perianal abscess (13 cases, 24%), followed by intestinal fistula (5 cases, 9%) and intestinal obstruction (4 cases, 7%). There was a significant difference in the incidence of intestinal complications among the three groups (P=0.0406). No intestinal complications were reported in the colonic group. CONCLUSIONS: Extraintestinal manifestations and intestinal complications are common in children with CD. Perianal examinations should be performed in children with suspected CD. Intestinal complications are less common in children with colonic CD, which may be associated with relatively mild disease condition.

OBJECTIVE: To investigate the incidence rate of infectious diseases during hospitalization in late preterm infants in Beijing, China, as well as the risk factors for infectious diseases and the effect of breastfeeding on the development of infectious diseases. METHODS: Related data were collected from the late preterm infants who were hospitalized in the neonatal wards of 25 hospitals in Beijing, China, from October 23, 2015 to October 30, 2017. According to the feeding pattern, they were divided into a breastfeeding group and a formula feeding group. The two groups were compared in terms of general status and incidence rate of infectious diseases. A multivariate logistic regression analysis was used to investigate the risk factors for infectious diseases. RESULTS: A total of 1 576 late preterm infants were enrolled, with 153 infants in the breastfeeding group and 1 423 in the formula feeding group. Of all infants, 484 (30.71%) experienced infectious diseases. The breastfeeding group had a significantly lower incidence rate of infectious diseases than the formula feeding group (22.88% vs 31.55%, P=0.033). The multivariate logistic regression analysis showed that breastfeeding was an independent protective factor against infectious diseases (OR=0.534, P=0.004), while male sex, premature rupture of membranes, gestational diabetes mellitus, and asphyxia were risk factors for infectious diseases (OR=1.328, 5.386, 1.535, and 2.353 respectively, P < 0.05). CONCLUSIONS: Breastfeeding can significantly reduce the incidence of infectious diseases and is a protective factor against infectious diseases in late preterm infants. Breastfeeding should therefore be actively promoted for late preterm infants during hospitalization.

We propose a quasi-counterfactual quantum swap gate for exchanging Alice's unknown photon state and Bob's unknown atomic state under the condition that only Alice's photon may appear in the transmission channel between Alice and Bob, while the probability of the existence of photon in the transmission channel is controllable and can tend to zero. Unlike standard counterfactual quantum communication protocols, quantum states exchange in present scenario is achieved by multiple phase operations, rather than multiple measurements. The total effect of those operations can be considered as a unitary time evolution operator. Therefore, the communication fidelity and efficiency of our protocol are always one if system imperfection and channel noise are not considered. Compared to standard counterfactual communication protocols, our protocol is easy to implement. We also show that it can be easily converted to a standard counterfactual one.
RESUMO
OBJECTIVE: To investigate the current enteral feeding practices in hospitalized late preterm infants in the Beijing area of China. METHODS: A multi-center, cross-sectional study was conducted. Infants born after 34 weeks and before 37 weeks of gestation were enrolled from 25 hospitals in the Beijing area of China from October 2015 to October 2017. Data on enteral feeding practices were collected and analyzed. RESULTS: A total of 1,463 late preterm infants were enrolled, with a mean gestational age (GA) of 35.6 (34.9, 36.1) weeks. The percentage of exclusive breastfeeding was 4.5% at the initiation of enteral feeding but increased to 14.4% at discharge. When human milk was not available, most infants (46.1%) were fed with preterm infant formula. The rate of exclusive human milk feeding in infants born at 34 weeks gestation was higher than at discharge (21.1% of infants born at 34 weeks' GA versus 12.1% of infants born at 35 weeks' GA versus 12.3% of infants born at 36 weeks' GA, P < 0.001). Only 28.4% of late preterm infants achieved full enteral feeding at discharge, and only 19.2% achieved 120 kcal/(kgâ¢d) by enteral feeding at discharge. Importantly, 40.5% of infants did not regain the birth weight at discharge. CONCLUSION: Enteral feeding support of late preterm infants has not been standardized to achieve optimal growth. Moreover, the human milk feeding rate was low, and many late preterm infants did not achieve the goal of enteral feeding and failed to regain birth weight at the time of discharge. More aggressive enteral feedings protocols are needed to promote human milk feeding and optimize growth for late preterm infants.

OBJECTIVE: To compare the feeding pattern of preterm infants between two hospitals in China and the United States. METHODS: A retrospective cohort study was conducted. Infants <32 weeks were enrolled from Cincinnati Children's Hospital Center Cincinnati University Hospital (CCHMC group) between January 2011 and January 2012 and Peking Union Medical College Hospital (PUMCH group) between January 2011 and May 2012. Enteral and parenteral feeding data of the two groups was compared. RESULTS: Eighty-two infants in the CCHMC group and 74 infants in the PUMCH group were enrolled. The gestational age and birth weight of infants in the CCHMC group were smaller than the PUMCH group (P<0.01). The total dosage of amino acid (58±30â g/kg vs 24.0(19.6, 32.8) g/kg; P<0.01) and fat [35±16â g/kg vs 14.0(11.0, 22.5) g/kg; P<0.01], in the PUMCH group were higher than the CCHMC group. The duration of parenteral nutrition in the PUMCH group was longer than the CCHMC group[(24±10â d vs 8.0(6.0, 11.0) d; P<0.01]. The breast feeding rate in the CCHMC group was higher (94% vs 10%; P<0.01) than in the PUMCH group. The time for achieving full enteral feeding in the CCHMC group was shorter [12.0(10.0, 14.0) d vs 22.4±9.3â d, P<0.01] than in the PUMCH group. The incidences of necrotizing enterocolitis (13% vs 3%; P<0.05) and sepsis (32% vs 12%; P<0.01) in the CCHMC group were higher than in the PUMCH group. CONCLUSIONS: Preterm infants in the PUMCH group have a prolonged duration of parenteral nutrition and an increased incidence of sepsis compared to the CCHMC group. Fortified human milk feeding and more aggressive enteral feeding proposal in PUMCH is recommended.

OBJECTIVE: To identify risk factors for Klebsiella pneumoniae carbapenemase-producing Klebsiella pneumoniae (KPC-Kp) colonization in neonates hospitalized in the neonatal intensive care unit (NICU). METHODS: A case-control study was conducted. The case group included nine patients colonized with KPC-Kp between 1 August 2012 and 31 April 2013 and the controls were selected randomly from patients without KPC-Kp colonization during the same period. Univariable analysis and multivariable logistic regression analysis were conducted to identify risk factors for KPC-Kp colonization. RESULTS: The univariable analysis showed 11 factors associated with KPC-Kp colonization: gestational age, birth weight, length of hospital stay, duration of mechanical ventilation, congenital heart disease, peripherally inserted central catheter, surgical operation, duration of intravenous nutrition, carbapenems use, duration of carbapenems use and glycopeptides use. The multivariable logistic regression analysis showed that exposure to more than 4 days of carbapenems use (OR=18.7, 95%CI: 1.98-175.5, P=0.01) was an independent risk factor for KPC-Kp colonization. The intervention to control KPC-Kp colonization included contact isolation, active surveillance, and rational use of antibiotics. CONCLUSIONS: Exposure to prolonged use of carbapenems is an independent risk factor for the development of KPC-Kp colonization in neonates hospitalized in the NICU.

BACKGROUND: Bradycardia-induced cardiomyopathy (BIC), which is a disease resulting from bradycardia, is characterized by cardiac chamber enlargement and diminished cardiac function. The correction of bradycardia can allow for significant improvements in both cardiac function and structure; however, this disease has been infrequently documented. In this case, we conducted a longitudinal follow-up of a patient who had been enduring BIC for more than 40 years to heighten awareness and prompt timely diagnosis and rational intervention. CASE SUMMARY: A woman who presented with postactivity fatigue and dyspnea was diagnosed with bradycardia at the age of 7. Since she had no obvious symptoms, she did not receive any treatment to improve her bradycardia during the 42-year follow-up, except for the implantation of a temporary pacemaker during labor induction surgery. As time progressed, the patient's heart gradually expanded due to her low ventricular rate, and she was diagnosed with BIC. In 2014, the patient developed atrial fibrillation, her ventricular rate gradually increased, and her heart shape gradually returned to normal. This report describes the cardiac morphological changes caused by the heart rate changes in BIC patients older than 40 years, introduces another possible outcome of BIC, and emphasizes the importance of early intervention in treating BIC. CONCLUSION: BIC can induce atrial fibrillation, causing an increased ventricular rate and leading to positive cardiac remodeling.
RESUMO
BACKGROUND: Endoscopic rubber band ligation (ERBL) is a nonsurgical technique for the treatment of symptomatic internal hemorrhoids but is limited by recurrence and post-procedural pain. AIM: To evaluate satisfaction, long-term recurrence, and post-procedural pain in managing internal hemorrhoids using a combination of polidocanol foam sclerotherapy and ERBL. METHODS: This was a prospective, multicenter, randomized study. A total of 195 consecutive patients diagnosed with grade II-III internal hemorrhoids were enrolled from four tertiary hospitals and randomly divided into a cap-assisted endoscopic polidocanol foam sclerobanding (EFSB) or an ERBL group. All patients were followed-up for 12 months. Symptom-based severity and post-procedural pain were assessed using a hemorrhoid severity score (HSS) and a visual analog scale (VAS). Continuous variables were reported as medians and interquartile range. RESULTS: One hundred and ninety-five patients were enrolled, with 98 in the EFSB group. HSS was lower in the EFSB group than in the ERBL group at 8 weeks [4.0 (3.0-5.0) vs 5.0 (4.0-6.0), P = 0.003] and 12-month [2.0 (1.0-3.0) vs 3.0 (2.0-3.0), P < 0.001] of follow-up. The prolapse recurrence rate was lower in the EFSB group at 12 months (11.2% vs 21.6%, P = 0.038). Multiple linear regression analysis demonstrated that EFSB treatment [B = -0.915, 95% confidence interval (CI): -1.301 to -0.530, P = 0.001] and rubber band number (B = 0.843, 95%CI: 0.595-1.092, P < 0.001) were negatively and independently associated with the VAS score 24 hours post-procedure. The median VAS was lower in the EFSB group than in the ERBL [2.0 (1.0-3.0) vs 3.0 (2.0-4.0), P < 0.001]. CONCLUSION: Cap-assisted EFSB provided long-term satisfaction and effective relief from the recurrence of prolapse and pain 24 hours post-procedure.

It has long been assumed in physics that for information to travel between two parties in empty space, "Alice" and "Bob," physical particles have to travel between them. Here, using the "chained" quantum Zeno effect, we show how, in the ideal asymptotic limit, information can be transferred between Alice and Bob without any physical particles traveling between them.

This study aimed to explore the molecular mechanisms underlying the differential quality of tea made from leaves at different development stages. Fresh Camellia sinensis (L.) O. Kuntze "Sichuan Colonial" leaves of various development stages, from buds to old leaves, were subjected to transcriptome sequencing and metabolome analysis, and the DESeq package was used for differential expression analysis, followed by functional enrichment analyses and protein interaction analysis. Target metabolome analysis indicated that the contents of most compounds, including theobromine and epicatechin gallate, were lowest in old leaves, and transcriptome analysis revealed that DEGs were significantly involved in extracellular regions and phenylpropanoid biosynthesis, photosynthesis-related pathways, and the oleuropein steroid biosynthesis pathway. Protein-protein interaction analysis identified LOC114256852 as a hub gene. Caffeine, theobromine, L-theanine, and catechins were the main metabolites of the tea leaves, and the contents of all four main metabolites were the lowest in old leaves. Phenylpropanoid biosynthesis, photosynthesis, and brassinosteroid biosynthesis may be important targets for breeding efforts to improve tea quality.

Objective: This study aims to investigate the predictive factors and efficacy of traditional Chinese medicine Shengji Ointment in the treatment of diabetic foot ulcers in the elderly population, with the intent of formulating an effective predictive model for deep diabetic foot ulcer healing. The importance of this research lies in its provision of new perspectives and tools for addressing the severe health impact of diabetic foot ulcers in the elderly population, considering the complexity and diversity of its treatment methods. Methods: The study includes 180 elderly patients with Wagner grade 3-4 diabetic foot ulcers that involve the tendon or fascia. The dependent variable is the initiation time of granulation tissue development. Independent variables encompass demographic information, a treatment strategy including Shengji Ointment, pre-treatment trauma assessment data, routine blood count, and biochemical index test results. Lasso regression is employed for variable selection, and Cox regression is utilized for the construction of a prediction model. A nomogram is generated to authenticate the model. Results: The Chinese Medicine treatment approach, ulcer location, creatinine levels, BMI, and haemoglobin levels are identified as independent predictors of granulation tissue development in diabetic foot ulcers. The combined treatment of Chinese herbal Shengji ointment and bromelain positively influenced granulation tissue development. The location of plantar ulcers, impaired renal functionality, obesity, and anaemia are established as independent risk factors that might influence the speed and probability of ulcer healing. The area under the time-dependent ROC curve fluctuates between 0.7 and 0.8, demonstrating substantial discrimination and calibration of the model. Conclusion: The study ascertains that a combined treatment strategy incorporating Shengji Ointment demonstrates greater effectiveness than the use of cleansing gel debridement alone in facilitating the healing of Wagner grade 3 or higher diabetic foot ulcers. Furthermore, the predictive model developed in this research serves as a valuable tool in evaluating the efficacy of Chinese Medicine treatments like Shengji Ointment for diabetic foot ulcers in the elderly. It aids clinicians in effectively assessing and adjusting treatment strategies, thereby proving its significant application value in clinical practice.

RESUMO
BACKGROUND: Large or transmural defects induced by gastrointestinal endoscopic manipulations are difficult to close, although complete closure is recommended for better recovery. Endoscopic purse-string assisted suturing (EPSS) has been used in clinical practice and has proven to be an effective and safe technique for the closure of large mucosal defects. However, details regarding the efficacy of endoscopic pre-purse-string suture (P-EPSS) are unknown, especially that it offers several advantages over conventional EPSS (C-EPSS). AIM: To elucidate the outcomes of EPSS-assisted closure in different clinical situations, and evaluate the efficacy of P-EPSS. METHODS: This retrospective observational study included a total of 180 patients who underwent closure assisted by P-EPSS (n = 63) or C-EPSS (n = 117) between July 2014 and June 2020. The P-EPSS and C-EPSS groups were compared and the intergroup differences in aspects such as the lesion size, location, and mor-phology, incidence of complete closure, intraoperative perforation, and delayed adverse events were evaluated. Data on the features and clinical course of cases with adverse events were collected for further analysis. RESULTS: Patients with lesion size larger than 3 cm, lesions located at the fundus of stomach, or submucosal tumors originating from the deep mucosa were more likely to undergo P-EPSS-assisted closure. The P-EPSS group showed a sign-ificantly higher proportion of intraoperative perforation (56% vs 17%) and a much shorter procedure time (9.06 ± 6.14 min vs 14.84 ± 7.25 min). Among adverse events, the incidence of delayed perforation (5% vs 4%; P = 0.82) and delayed bleeding (3% vs 4%; P = 0.96) did not differ significantly between the groups. Multivariate analysis revealed that lesions with incomplete closure [odds ratio (OR) = 21.33; 95% confidence interval (CI): 5.45-83.45; P < 0.01] or size greater than 3 cm (OR = 3.14; 95%CI: 1.08-9.18; P = 0.039) showed a statistical tendency to result in an increase in delayed adverse events. CONCLUSION: The present study revealed that EPSS could achieve secure complete closure of mucosal defect. P-EPSS could shorten the procedure and yield complete closure of mucosal defects. Rather than closure-type selection, incomplete closure or lesion size larger than 3 cm were associated with worse outcomes.

OBJECTIVE: To examine the esophageal function of neonates by high resolution manometry (HRM), and to provide preliminary data for research on the esophageal function of neonates. METHODS: Esophageal HRM was performed on neonates using a solid-state pressure measurement system with 36 circumference sensors arranged at intervals of 0.75 cm, and ManoView software was used to analyze esophageal peristalsis pattern. RESULTS: Esophageal HRM was performed successfully in 11 neonates, and 126 occurrences of complete esophageal peristalsis were recorded. Complete esophageal peristalsis with pressure increase was recorded in some neonates but most neonates showed a different esophageal peristalsis pattern compared with adults. Some neonates had no relaxation of the upper esophageal sphincter (UES) when pharyngeal muscles contracted in swallowing, some neonates had multiple swallowing without esophageal peristalsis and some neonates had relatively low pressure of esophageal peristalsis. Full-term infants could have relatively low UES pressure and esophageal sphincter (LES) pressure but some preterm infants showed relatively high UES pressure and LES pressure. Longitudinal contraction of the whole esophagus and elevation of LES after swallowing were recorded in some neonates. CONCLUSIONS: Esophageal HRM is safe and tolerable for neonates. HRM shows that esophageal peristalsis after swallowing may not occur or may be incomplete in neonates. The esophageal function of neonates has not yet been developed completely, with large individual differences in esophageal peristalsis. Large sample data are needed for further analysis and research on the esophageal function of neonates.
