PURPOSE: The rate of complications among patients undergoing surgery has increased due to infection with SARS-CoV-2 and other variants of concern. However, Omicron has shown decreased pathogenicity, raising questions about the risk of postoperative complications among patients who are infected with this variant. This study aimed to investigate complications and related factors among patients with recent Omicron infection prior to undergoing orthopedic surgery. METHODS: A historical control study was conducted. Data were collected from all patients who underwent surgery during 2 distinct periods: (1) between Dec 12, 2022 and Jan 31, 2023 (COVID-19 positive group), (2) between Dec 12, 2021 and Jan 31, 2022 (COVID-19 negative control group). The patients were at least 18 years old. Patients who received conservative treatment after admission or had high-risk diseases or special circumstances (use of anticoagulants before surgery) were excluded from the study. The study outcomes were the total complication rate and related factors. Binary logistic regression analysis was used to identify related factors, and odds ratio (OR) and 95% confidence interval (CI) were calculated to assess the impact of COVID-19 infection on complications. RESULTS: In the analysis, a total of 847 patients who underwent surgery were included, with 275 of these patients testing positive for COVID-19 and 572 testing negative. The COVID-19-positive group had a significantly higher rate of total complications (11.27%) than the control group (4.90%, p < 0.001). After adjusting for relevant factors, the OR was 3.08 (95% CI: 1.45-6.53). Patients who were diagnosed with COVID-19 at 3-4 weeks (OR = 0.20 (95% CI: 0.06-0.59), p = 0.005), 5-6 weeks (OR = 0.16 (95% CI: 0.04-0.59), p = 0.010), or ≥7 weeks (OR = 0.26 (95% CI: 0.06-1.02), p = 0.069) prior to surgery had a lower risk of complications than those who were diagnosed at 0-2 weeks prior to surgery. Seven factors (age, indications for surgery, time of operation, time of COVID-19 diagnosis prior to surgery, C-reactive protein levels, alanine transaminase levels, and aspartate aminotransferase levels) were found to be associated with complications; thus, these factors were used to create a nomogram. CONCLUSION Omicron continues to be a significant factor in the incidence of postoperative complications among patients undergoing orthopedic surgery. By identifying the factors associated with these complications, we can determine the optimal surgical timing, provide more accurate prognostic information, and offer appropriate consultation for orthopedic surgery patients who have been infected with Omicron.

Objective:To investigate the risk factors for sepsis in patients severe trauma.Methods:A retrospective case-control study was conducted to analyze the clinical data of 149 patients with severe trauma admitted to General Hospital of Ningxia Medical University from January 2021 to June 2022, including 112 males and 37 females, aged 18-93 years [(50.6±16.3)years]. According to whether the patients developed sepsis, they were divided into sepsis group ( n=66) and non-sepsis group ( n=83). A comparison was made between the two groups in gender, age, measurements of body temperature, heart rate, respiration, systolic blood pressure, diastolic blood pressure, mean artery pressure (MAP), oxygen saturation (SPO 2), white blood cell (WBC), absolute neutrophil count (ANC), percentage of neutrophils (NEUT%), red blood cell count (RBC), hemoglobin (HGB), platelet count (PLT), prothrombin time (PT), activated partial thromboplastin time (APTT), D-dimer level, level of lactic acid, level of blood glucose, quick sequential organ failure assessment (qSOFA), sequential organ failure assessment (SOFA), acute physiology and chronic health evaluation II (APACHE II) score, Glasgow coma scale (GCS), and injury severity score (ISS) within 24 hours of admission, causes of injury, injury sites, number of injury sites, hemorrhagic shock (HS), open injury, endotracheal intubation, length of ICU stay and total length of hospital stay. Univariate analysis and multivariate Logistic regression analysis were used to determine the independent risk factors for severe post-traumatic sepsis. Results:The results of univariate analysis showed that there were statistically significant differences in age, respiration, SPO 2, WBC and ANC, D-dimer level, blood glucose level, qSOFA, SOFA, APACHE II score, GCS, ISS, head and neck injury, open injury, tracheal intubation, length of ICU stay, and total length of hospital stay between the sepsis group and non-sepsis group ( P<0.05 or 0.01); whereas there were no significant differences in gender, underlying disease, body temperature, heart rate, systolic blood pressure, diastolic blood pressure, MAP, NEUT%, RBC, HGB, PLT, PT, APTT, lactic acid level, cause of injury, facial injury, chest injury, abdominal and pelvic injury, limb and pelvic injury, number of injury sites, and HS between the two groups ( P>0.05). Multivariate Logistic regression analysis showed that D-dimer level ( OR=0.97, 95% CI 0.96, 0.99, P<0.01) and tracheal intubation ( OR=15.80, 95% CI 2.14, 116.69, P<0.01) were significantly correlated with sepsis in patients with severe trauma. Conclusion:D-dimer level collected within 24 hours of admission and tracheal intubation are independent risk factors for sepsis in patients with severe trauma.

Objective:To understand the breastfeeding situation in the neonatal intensive care units (NICUs) in Qianxinan Prefecture, Guizhou Province, and to assess the knowledge, attitudes, and practices of doctors and nurses regarding breastfeeding, aiming to provide foundational data for improving breastfeeding quality.Methods:A questionnaire was developed to survey the knowledge, attitudes, and practices related to breastfeeding in NICUs. The questionnaire was divided into three dimensions: knowledge (seven items, total score of 7), attitudes (nine items, total score of 45), and practices (seven items, total score of 35). Lower scores indicated weaker recognition of breastfeeding. Additionally, five items were included to identify the most influential factors affecting breastfeeding. From November 25 to November 30, 2023, a survey was conducted among doctors and nurses with professional qualifications who had worked in the neonatal departments of nine hospitals in Qianxinan Prefecture for at least one year. Independent sample t-tests and Chi-square tests were used to compare the scores of doctors and nurses from different levels of hospitals and within the same level of hospitals across the three dimensions. Results:(1) Among the nine hospitals, three were tertiary grade A hospitals (referred to as "tertiary hospitals"), with 95.6% (43/45) of the doctors and 96.5% (110/114) of the nurses participating in the survey. Six were secondary grade A hospitals (referred to as "secondary hospitals"), with 95.0% (38/40) of the doctors and 97.6% (83/85) of the nurses participating. (2) All nine hospitals were baby-friendly hospitals and all had breastfeeding promotional materials. Six hospitals had NICUs that promoted breastfeeding, with an average NICU breastfeeding rate of 25.8% across the prefecture between year 2021 to 2023. (3) The proportion of doctors who had received breastfeeding training was higher than that of nurses within the same level of hospitals [tertiary hospitals: 69.8% (30/43) vs. 40.0% (44/110), χ 2=10.97, P=0.001; secondary hospitals: 47.4% (18/38) vs. 24.1% (20/83), χ 2=6.55, P=0.010], although the overall training rates were low. (4) In tertiary hospitals, doctors scored higher than nurses in the attitude dimension [(35.35±4.75) vs. (33.18±5.60) scores, t=－2.03, P=0.044] and also in the practice dimension [(26.98±3.00) vs. (25.60±3.75) scores, t=－2.17, P=0.032]. In secondary hospitals, the total knowledge dimension score of doctors was higher than that of nurses [(4.92±1.44) vs. (4.20±1.45) scores, t=－2.52, P=0.013]. In tertiary hospitals, the total scores for attitude and practice dimensions of doctors were higher than those of doctors in secondary hospitals, and the total scores for knowledge, attitude, and practice dimensions of nurses were higher than those of nurses in secondary hospitals (all P<0.05). (5) In the knowledge dimension, the lowest scoring item of doctors in the tertiary hospitals was "Breastfeeding is possible for maternal hepatitis B newborns after receiving vaccines and immunoglobulin"; the lowest scoring item of nurses in the tertiary hospital, and doctors and nurses in the secondary hospitals was "The duration of breastfeeding has a greater impact on neonatal outcomes". In the attitude dimension, the lowest scoring item for doctors and nurses in both tertiary and secondary hospitals was "You think the breastfeeding process is more troublesome than feeding preterm formula". In the practice dimension, the lowest scoring item of the doctors and nurses in the tertiary hospitals was "Your hospital had enough breastfeeding knowledge training", while for the doctors and nurses in the secondary hospitals were "You have more opportunities to participate in various breastfeeding-related training" and "Breast feeding should be started as soon as possible when the infant is stable after active treatment", respectively. (6) The most influential factors affecting breastfeeding were: lack of cooperation from parents (50.0%, 137/274), relative insufficient human resources for doctors and nurses (21.9%, 60/274), and the absence or poor implementation of breastfeeding management policies (18.3%, 50/274), etc. Conclusions:The breastfeeding rate in NICU of county-level hospitals is relatively low, and medical staff, especially nurses, have insufficient knowledge about breastfeeding. It is necessary to strengthen various breastfeeding training for medical staff to enhance their understanding of NICU breastfeeding.

Objective:To explore the current situation of nursing human caring in hospital wards and analyze its influencing factors, so as to facilitate the development of nursing human caring practice.Methods:From July to November 2022, a total of 107 hospitals were surveyed through stratified convenience sampling method, and 4 072 ward nursing managers were recruited to finish the general information questionnaire and the ward nursing human caring status questionnaire. The general information included the region, class and type of the hospital, etc. The ward nursing human caring status questionnaire included 38 items in 5 dimensions of nursing human caring system and process, humanistic quality and training of nursing staff, humanistic environment and facilities, human caring procedures and measures, and human caring quality evaluation and improvement, with a full score of 190 points. Descriptive statistics were used to analyze the general data, independent samples t-test, ANOVA and correlation analysis were used to analyze the factors influencing the current status of nursing human caring in the ward, while multiple linear regression analysis was used to conduct a multivariate analysis. Results:The score of nursing human caring in hospital wards was 156.91±27.78. Whether the hospital had carried out nursing human caring pilot(demonstration) wards, whether the ward had previously been a hospital nursing human caring pilot(demonstration) nursing unit, the type of ward, and whether nursing managers had participated in human caring training were the influencing factors of the implication of nursing humanistic caring in wards( P<0.05). Conclusions:The practice of nursing human caring in hospital wards is at a good level, but needs to be further strengthened. Nursing managers should take systematically strategies to promote the development of nursing human caring practice.

OBJECTIVE: To assess the efficacy and safety of Guanxin Danshen Dripping Pills (GXDS) in the treatment of depression or anxiety in patients with coronary heart disease (CHD) after percutaneous coronary intervention (PCI). METHODS: From September 2017 to June 2019, 200 CHD patients after PCI with depression and anxiety were included and randomly divided into GXDS (100 cases) and placebo control groups (100 cases) by block randomization and a random number table. Patients in the GXDS and control groups were given GXDS and placebo, respectively, 0.4 g each time, 3 times daily for 12 weeks. The primary outcomes were scores of Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Scale (GAD-7) and the Seattle Angina Pectoris Scale (SAQ). The secondary outcomes included 12 Health Survey Summary Form (SF-12) scores and the first onset time and incidence of major adverse cardiovascular events (MACEs). Other indices including blood pressure, blood lipids, microcirculation and inflammatory-related indices, etc. were monitored at baseline, week 4, and week 12. RESULTS: In the full analysis set (200 cases), after treatment, the PHQ-9 and GAD-7 scores in the GXDS group were considerably lower than those in the control group (P<0.05). Compared with the baseline, the total PHQ-9 scores of the experimental and control groups decreased by 3.97 and 1.18, respectively. The corrected mean difference between the two groups was -2.78 (95% CI: -3.47, -2.10; P<0.001). The total GAD-7 score in the GXDS group decreased by 3.48% compared with the baseline level, while that of the placebo group decreased by 1.13%. The corrected mean difference between the two groups was -2.35 (95% CI: -2.95, -1.76; P<0.001). The degree of improvement in SAQ score, SF-12 score, endothelin and high-sensitive C-reactive protein levels in the GXDS group were substantially superior than those in the placebo group, and the differences between the two groups were statistically significant (P<0.05). Similar results were obtained in the per protocol population analysis of 177 patients. Three cases of MACES were reported in this study (1 in the GXDS group and 2 in the placebo group), and no serious adverse events occurred. CONCLUSIONS GXDS can significantly alleviate depression and anxiety, relieve symptoms of angina, and improve quality of life in patients with CHD after PCI. (Registration No. ChiCTR1800014291).

AIM: To investigate the effect of Conbercept on serum lncRNA MALAT1 levels, central macular thickness(CMT)and best corrected visual acuity(BCVA)in patients with diabetic macular edema(DME), and to observe its efficacy and safety.METHODS: A total of 300 patients(300 eyes)with DME were included in this study, all of whom had monocular lesions. They were divided into non-injection group with 100 patients(100 eyes), control group with 100 patients(100 eyes)treated with Ranibizumab injections and study group with 100 patients(100 eyes)treated with Conbercept injections according to a random numbers table.RESULTS: The BCVA, serum lncRNA MALAT1 level and CMT were measured before and 1, 2 and 3mo after treatment. In addition, the clinical efficacy was assessed and the patients were followed up to record the adverse reactions. There were no significant changes in BCVA(LogMAR), serum lncRNA MALAT1 level and CMT in the non- injection group(P>0.05). The BCVA(LogMAR)in the control group and study group at 1, 2 and 3mo after treatment was significantly higher than that before treatment(all P<0.05). The BCVA(LogMAR)of patients in the study group at 1, 2 and 3mo after treatment was significantly higher than that before treatment(all P<0.05), but there was no significant difference between the study group and control group. The level of serum lncRNA MALAT1 in the control group decreased at 1, 2 and 3mo after treatment, and it decreased more significantly in the study group at 1, 2 and 3mo after treatment. The level of serum lncRNA MALAT1 in the study group was significantly lower than that in the control group(all P<0.05).The CMT of patients in the control group decreased at 1, 2 and 3mo after treatment; however, the CMT of patients in the study group decreased more significantly at 1, 2 and 3mo after treatment. The CMT of the study group was significantly lower than that of the control group(all P<0.05).The incidence of adverse reactions in the study group(2.0%)was significantly lower than that in the control group(11.0%).CONCLUSION: Conbercept can significantly reduce the level of serum lncRNA MALAT1, CMT and macular edema and improve BCVA in patients with DME. Its therapeutic efficacy and safety are significantly better than Ranibizumab.

The application status of acupuncture and moxibustion therapy for assisted reproductive field in the United States was analyzed, and the existing problems and future development directions were discussed. According to the survey on the 456 websites of assisted reproductive clinic in the United States mentioned in the report of U.S. Centers for Disease Control and Prevention (CDC), 111 clinics among 456 assisted reproductive clinics recommend and used acupuncture and moxibustion therapy, accounting for 24.3%. Acupuncture and moxibustion therapy had obvious effect, good safety and low cost, and the assisted reproductive institutions in the United States had a high degree of application and recognition to acupuncture and moxibustion therapy. However, some problems, such as immature treatment scheme, unclear mechanism and imperfect insurance policies, still existed. In the future, the advantages of Chinese traditional acupuncture and moxibustion should combine with international modern assisted reproductive technology, and multi-center and large-sample clinical randomized controlled trials and basic experimental research on the mechanism of acupuncture and moxibustion for assisted reproduction should be carried out.

Incorporation of multiple functions into one nanoplatform can improve cancer diagnostic efficacy and enhance anti-cancer outcomes. Here, we constructed doxorubicin (DOX)-loaded silk fibroin-based nanoparticles (NPs) with surface functionalization by photosensitizer (N770). The obtained nanotheranostics (N770-DOX@NPs) had desirable particle size (157 nm) and negative surface charge (-25 mV). These NPs presented excellent oxygen-generating capacity and responded to a quadruple of stimuli (acidic solution, reactive oxygen species, glutathione, and hyperthermia). Surface functionalization of DOX@NPs with N770 could endow them with active internalization by cancerous cell lines, but not by normal cells. Furthermore, the intracellular NPs were found to be preferentially retained in mitochondria, which were also efficient for near-infrared (NIR) fluorescence imaging, photothermal imaging, and photoacoustic imaging. Meanwhile, DOX could spontaneously accumulate in the nucleus. Importantly, a mouse test group treated with N770-DOX@NPs plus NIR irradiation achieved the best tumor retardation effect among all treatment groups based on tumor-bearing mouse models and a patient-derived xenograft model, demonstrating the unprecedented therapeutic effects of trimodal imaging-guided mitochondrial phototherapy (photothermal therapy and photodynamic therapy) and chemotherapy. Therefore, the present study brings new insight into the exploitation of an easy-to-use, versatile, and robust nanoplatform for programmable targeting, imaging, and applying synergistic therapy to tumors.
