Abstract
Objective To observe the effect of Pseudomonas aeruginosa mannose-sensitive hemagglutinin (PA-MSHA) on the prognosis and the incidence of lymphatic leakage in patients undergoing radical cystectomy (RC). Method A total of 129 patients who underwent RC in Lanzhou University Second Hospital from 2013 to 2022 were enrolled in this study. They were divided into 43 patients treated with PA-MSHA and 86 patients in the control group. Inverse probability of treatment weighting (IPTW) was applied to reduce potential selection bias. Kaplan-Meier method and Cox regression analysis were used to analyze the effect of PA-MSHA on the survival of patients and the incidence of postoperative lymphatic leakage. Results The PA-MSHA group exhibited improved overall survival (OS) and cancer-specific survival (CSS) rates compared to the control group. The 3-year and 5-year overall survival (OS) rates for the PA-MSHA group were 69.1% and 53.2%, respectively, compared to 55.6% and 45.3% for the control group (Log-rank=3.218, P=0.072). The 3-year and 5-year cancer-specific survival (CSS) rates for the PA-MSHA group were 73.3% and 56.5%, respectively, compared to 58.0% and 47.3% for the control group (Log-rank=3.218, P=0.072). Additionally, the 3-year and 5-year progression-free survival (PFS) rates for the PA-MSHA group were 74.4% and 56.8%, respectively, compared to 57.1% and 52.2% for the control group (Log-rank=2.016, P=0.156). Multivariate Cox regression analysis indicates that lymph node metastasis and distant metastasis are poor prognostic factors for patients, while the use of PA-MSHA can improve patients' OS (HR: 0.547, 95%CI: 0.304-0.983, P=0.044), PFS (HR: 0.469, 95%CI: 0.229-0.959, P=0.038) and CSS (HR: 0.484, 95%CI: 0.257-0.908, P=0.024). The same trend was observed in the cohort After IPTW adjustment. Although there was no significant difference in the incidence of postoperative lymphatic leakage [18.6% (8/35) vs. 15.1% (84.9%), P=0.613] and pelvic drainage volume [470 (440) ml vs. 462.5 (430) ml, P=0.814] between PA-MSHA group and control group, PA-MSHA could shorten the median retention time of drainage tube (7.0 d vs 9.0 d) (P=0.021). Conclusion PA-MSHA may improve radical cystectomy in patients with OS, PFS, and CSS, shorten the pelvic drainage tube retention time.

Abstract
Pseudomonas aeruginosa is a Gram-negative opportunistic pathogen that causes high morbidity and mortality in cystic fibrosis (CF) and immunocompromised patients, including patients with ventilator-associated pneumonia (VAP), severely burned patients, and patients with surgical wounds. Due to the intrinsic and extrinsic antibiotic resistance mechanisms, the ability to produce several cell-associated and extracellular virulence factors, and the capacity to adapt to several environmental conditions, eradicating P. aeruginosa within infected patients is difficult. Pseudomonas aeruginosa is one of the six multi-drug-resistant pathogens (ESKAPE) considered by the World Health Organization (WHO) as an entire group for which the development of novel antibiotics is urgently needed. In the United States (US) and within the last several years, P. aeruginosa caused 27% of deaths and approximately USD 767 million annually in health-care costs. Several P. aeruginosa therapies, including new antimicrobial agents, derivatives of existing antibiotics, novel antimicrobial agents such as bacteriophages and their chelators, potential vaccines targeting specific virulence factors, and immunotherapies have been developed. Within the last 2-3 decades, the efficacy of these different treatments was tested in clinical and preclinical trials. Despite these trials, no P. aeruginosa treatment is currently approved or available. In this review, we examined several of these clinicals, specifically those designed to combat P. aeruginosa infections in CF patients, patients with P. aeruginosa VAP, and P. aeruginosa-infected burn patients.

Abstract
BACKGROUND To investigate the related factors affecting the postoperative indwelling time of drainage tubes (hereinafter referred to as drainage time) in breast cancer (BC) and evaluate the effect of Pseudomonas aeruginosa-mannose-sensitive hemagglutinin (PA-MSHA) preparation on reducing postoperative drainage time. METHODS The clinical data of 165 BC patients in our hospital, including the postoperative drainage time and occurrence of seroma and related complications (such as fever, incision infection, and flap necrosis) after extubation, were retrospectively analyzed. Univariate, multivariate, and stratified analyses were used to determine the correlations between 15 factors including age, body weight, body mass index (BMI), and PA-MSHA preparation, and the postoperative total drainage volume and drainage time. RESULTS Age, BMI, and PA-MSHA preparation were independent factors affecting the postoperative drainage volume and drainage time of BC patients. Age and BMI were positively correlated with postoperative drainage volume and drainage time (P≤0.004, P≤0.037). PA-MSHA preparation significantly reduced the postoperative total drainage volume and drainage time (P<0.001), decreased the incidence of seroma after extubation (P=0.024), and did not increase complications (P>0.05). CONCLUSIONS Obese and elderly patients were at a significantly high risk of a high drainage volume and long drainage time. Local treatment with PA-MSHA preparation had the advantages of reducing postoperative drainage volume, reducing drainage time, preventing seroma, and not increasing complications, and was a safe and effective treatment. For BC patients aged over 60 years and with a BMI ≥25, the intraoperative local spraying of wounds with PA-MSHA preparation to reduce postoperative drainage times is a valuable option.

Surgical Skills and Technological Advancements to Avoid Complications in Lateral Neck Dissection for Differentiated Thyroid Cancer. Cancers (Basel) 2021; 13:cancers13143379.

Abstract
Neck dissection is a surgical procedure reserved for thyroid cancer cases with clinically evident lymphatic invasion. Although neck dissection is a reliable and safe procedure, it can determine a significant morbidity involving a variety of structures of nervous, vascular and endocrine typology. A careful pre-operative study is therefore essential to better plan surgery. Surgical experience, combined with accurate surgical preparation and merged with adequate and specific techniques, can certainly help reduce the percentage of complications. In recent years, however, technology has also proved to be useful. Its crucial role was already recognized in the safeguard of the integrity of the laryngeal nerve through neuro-monitoring, but new technologies are emerging to help the preservation also of the parathyroid glands and other structures, such as the thoracic duct. These surgical skills combined with the latest technological advancements, that allow us to reduce the incidence of complications after neck dissection for thyroid cancer, will be reported in the present article. This topic is of significant interest for the endocrine and metabolic surgeons' community.

Abstract
Background Pseudomonas aeruginosa injection (PAI) has been proven effective against chylous fistula but not in decreasing drainage after lateral neck dissection (LND). To verify the safety of spraying PAI onto the surface of the traumatic cavity after total thyroidectomy with LND and to evaluate whether its application can reduce the drainage volume. Methods A total of 85 patients with metastatic papillary thyroid cancer (PTC) who agreed to total thyroidectomy with unilateral LND were recruited from March 2016 to September 2017. During the operation, PAI was applied in 44 patients, while 41 remaining patients served as the control group. The thyroid function and parathyroid function, drainage volume, hospital stay, and incidence of complications were compared between the two groups. Results The groups had few differences in age, gender, BMI, thyroid function, parathyroid function, diameter of tumor, and the number of the harvested lymph nodes. The median total drainage volume was significantly smaller and the mean hospital stay was obviously shorter in the PAI group compared to the non-PAI group. But the median volumes of peak 24-hour drainage which appeared during the first day after operation had few differences in the two groups. Postoperative fever in the PAI group was higher than in the non-PAI group. None of the patients had permanent recurrent laryngeal nerve paralysis and tumor recurrence on the 12th month after operation. Conclusions The application of PAI to the wound cavity after LND is safe and effective for reducing the drainage volume and hospital stay.
