BACKGROUND: Poly adenosine-diphosphate-ribose polymerase (PARP) inhibitors (PARPi) have been approved to act as first-line maintenance (FL-M) therapy and as platinum-sensitive recurrent maintenance (PSR-M) therapy for ovarian cancer in China for >5 years. Herein, we have analyzed the clinical-application characteristics of olaparib and niraparib in ovarian cancer-maintenance therapy in a real-world setting to strengthen our understanding and promote their rational usage. METHODS: A retrospective chart review identified patients with newly diagnosed or platinum-sensitive recurrent ovarian cancer, who received olaparib or niraparib as maintenance therapy at Sichuan Cancer Hospital between August 1, 2018, and December 31, 2021. Patient medical records were reviewed. We grouped and analyzed patients based on the type of PARPi they used (the olaparib group and the niraparib group) and the line of PARPi maintenance therapy (the FL-M setting and the PSR-M setting). The primary endpoint was the 24-month progression-free survival (PFS) rate. RESULTS: In total, 131 patients (olaparib: n = 67, 51.1%; niraparib: n = 64, 48.9%) were enrolled. Breast cancer susceptibility genes ( BRCA ) mutations ( BRCA m) were significantly less common in the niraparib group than in the olaparib group [9.4% (6/64) vs . 62.7% (42/67), P <0.001], especially in the FL-M setting [10.4% (5/48) vs . 91.4% (32/35), P <0.001]. The 24-month progression-free survival (PFS) rates in the FL-M and PSR-M settings were 60.4% and 45.7%, respectively. In patients with BRCA m, the 24-month PFS rates in the FL-M and PSR-M settings were 62.2% and 72.7%, respectively. CONCLUSIONS Olaparib and niraparib were effective in patients with ovarian cancer without any new safety signals except for skin pigmentation. In patients with BRCA m, the 24-month PFS of the PARPi used in the PSR-M setting was even higher than that used in the FL-M setting.

OBJECTIVE: To describe a novel arthroscopic technique of modified tri-anchor double-pulley suture-bridge in repairing medium-sized supraspinatus tendon tears and evaluate the early effectiveness. METHODS: Between June 2021 and January 2024, 26 patients with medium-sized supraspinatus tendon tears who underwent arthroscopic modified tri-anchor double-pulley suture-bridge repair and met the selective criteria were included. There were 11 males and 15 females with an average age of 61.4 years (range, 43-74 years). Five patients had a significant history of trauma, while the remaining 21 patients had no apparent cause. The time from symptom onset to hospitalization was 3-25 months (mean, 7.9 months). The effectiveness was evaluated during follow-up, including the scores of University of California at Los Angeles (UCLA), American Shoulder and Elbow Surgeons (ASES), visual analogue scale (VAS), the range of forward flexion, abduction, external rotation, and internal rotation, and patient's satisfaction. Either MRI or ultrasound examination were used to evaluate structural integrity of the tendon. RESULTS: The operation time was 65-110 minutes (mean, 81.8 minutes). All patients were followed up 12-43 months (mean, 23.0 months). At 3 and 12 months after operation, the shoulder range of flexion, abduction, external rotation, and internal rotation, and the scores of VAS, UCLA, and ASES significantly improved when compared with those before operation ( P<0.05). The improvement was further observed at 12 months compared to 3 months ( P<0.05). At last follow-up, 13 patients were very satisfied with the effectiveness, 11 patients were satisfied, 1 was relatively satisfied, and 1 was dissatisfied. During follow-up, 15 patients underwent imaging examination and imaging reexamination showed that the re-tear rate of tendon was 6.6%(1/15). The remaining 11 patients refused imaging examination. Complications included partial anchor withdrawal in 1 case, shoulder stiffness in 5 cases, and mild pain in shoulder joint in 2 cases in physical activity or heavy physical activity. CONCLUSION Arthroscopic modified tri-anchor double-pulley suture-bridge technique is a novel surgical technique that uses double-loaded suture anchors as medial- and lateral-row anchors. In repairing medium-sized supraspinatus tendon tears, 6 sets of double-pulley suture-bridges can be created from one medial-row anchor; knotless medial-row can reduce re-tear rate of the tendon; good early effectiveness is obtained.

In recent years,the infection of nontuberculous mycobacterium(NTM)has been increasing rapidly,which captivates widespread attention.The infection rate of NTM in kidney transplant recipients is more significantly elevated due to the impact of immunosuppressive drugs and other factors.However,due to the lack of sufficient research evidence,relevant guidelines for the diagnosis and treatment of NTM after kidney transplantation are still lacking.To further standardize the diagnosis and treatment of NTM disease in kidney transplant recipients,and deepen medical practitioners'understanding and diagnosis and treatment of NTM disease in organ transplantation in China,Branch of Organ Transplantation of Chinese Medical Association organized relevant experts to formulate this guideline by referring to the latest edition of"An official ATS/IDSA statement:diagnosis,treatment,and prevention of nontuberculous mycobacterial diseases","Expert Consensus on the Diagnosis and Treatment of Nontuberculous Mycobacterial Disease",and"Technical Specification for Clinical Diagnosis and Treatment of Nontuberculous Mycobacteria in Organ Transplant Recipients(2019 Edition)",and considering the characteristics of kidney transplant recipients.

OBJECTIVE: To investigate short-term effectiveness of arthroscopic repair via modified subacromial viewing portal (hereinafter referred to as modified viewing portal) in treatment of LafosseⅠsubscapularis tendon tears. METHODS: A clinical data of 52 patients with LafosseⅠsubscapularis tendon tears, who underwent the arthroscopic repair via modified viewing portal between October 2020 and November 2022 and met the selective criteria, was retrospectively analyzed. There were 15 males and 37 females with an average age of 63.4 years (range, 41-76 years). Twelve patients had trauma history and the other 40 patients had no obvious inducement. The main clinical symptom was shoulder pain and the hug resistance tests were positive in all patients. The interval between symptom onset and admission ranged from 3 to 26 months (mean, 7.2 months). The shoulder pain and function were evaluated by visual analogue scale (VAS) score, American Shoulder and Elbow Surgeons (ASES) score, and University of California Los Angeles (UCLA) score before operation and at 12 months after operation. The shoulder range of motion (ROM) of forward flexion, abduction, and external rotation and the internal rotation strength were measured before operation and at 3 and 12 months after operation. MRI was performed at 3-6 months after operation to assess the tendon healing and the structural integrity and tension of reattached tendon. Patient's satisfactions were calculated at last follow-up. RESULTS: All incisions healed by first intention, no complication such as incision infection or nerve injury occurred. All patients were followed up 12-37 months (mean, 18.5 months). The VAS, UCLA, and ASES scores at 12 months after operation significantly improved when compared with those before operation ( P<0.05). The ROMs of abduction and forward flexion and the internal rotation strength at 3 and 12 months significantly improved when compared with those before operation ( P<0.05); and the ROMs at 12 months significantly improved compared to that at 3 months ( P<0.05). However, there was no significant difference ( P>0.05) in the ROM of external rotation at 3 months compared to that before operation; but the ROM at 12 months significantly improved compared to that before operation and at 3 months after operation ( P<0.05). Thirty-one patients underwent MRI at 3-6 months, of which 28 patients possessed intact structural integrity, good tendon tension and tendon healing; 3 patients underwent tendon re-tear. At last follow-up, 41 patients (78.8%) were very satisfied with the effectiveness, 7 were satisfied (13.5%), and 4 were dissatisfied (7.7%). CONCLUSION Arthroscopic repair via modified viewing portal for Lafosse Ⅰsubscapularis tendon tears, which can achieve the satisfactory visualization and working space, can obtain good short-term effectiveness with low overall re-tear risk.

Objective:To analyze the operational efficiency of the oncology department in multi-campus hospital, providing reference for rational resource allocation and efficiency enhancement.Methods:A certaion tertiary grade A Hospital is a multi-campus public hospital with integrated management. This study focused on its oncology department, with 9 wards located in different campus as decision-making units. Data from 2020 to 2022 were extracted from the hospital′s medical records management system, disease diagnosis-related groups management system, and hospital information system. The super-efficiency DEA model and Malmquist index model were used to evaluate efficiency variations of the oncology department in different time slots and decision-making units. Identifying input redundancies and output deficiencies in wards not achieving constant returns to scale through projection value analysis. Selecting the total number of medical staff and the actual total number of bed-days occupied as input indicators, while bed utilization rate, discharge rate, and case mix index as output indicators.Results:From 2020 to 2022, the wards with a DEA super-efficiency value greater than 1 were 0, 2, and 4, respectively, showing a gradual increase in overall efficiency. In 2022, wards S3, S4, S7, and S9 achieved constant returns to scale with super-efficiency values of 1.001, 1.005, 1.113, and 1.112, respectively. The other five wards had zero input redundancy, but some suffered from insufficient outputs. For example, wards S5 and S8 should increase their bed utilization rates by 5% and 4%, respectively. Wards S1 and S8 needed to increase their annual discharge numbers by 24% and 1%, respectively, while wards S2 and S6 should increase their annual case mix index by 21% and 20%, respectively. From 2020 to 2021, the Malmquist index of the oncology department was 0.959, while from 2021 to 2022 it rose to 1.030, and the Malmquist index of each ward was greater than 1.Conclusions:By implementing integrated management across multiple campus, the operational efficiency of the oncology department has been comprehensively improved. The use of the super efficient DEA-Malmquist index model to evaluate the operational efficiency of departments has practical significance.

Objective:To analyze the mutation types and distribution characteristics of thalassemia gene among high-risk populations in Sanya City, and to evaluate the effectiveness of blood routine screening, in order to provide scientific basis for formulating measures for prevention and control of thalassemia in Sanya City.Methods:Retrospective analysis was used to collect detection results and clinical data from high-risk individuals who completed genetic screening for thalassemia at Sanya Materal and Child Health Hospital from January 2019 to August 2021. Mutation types and distribution characteristics of thalassemia gene were analyzed, and the missed detection rate and sensitivity of blood routine indicators [mean corpuscular volume (MCV) and mean corpuscular hemoglobin (MCH)] were evaluated based on the results of genetic screening for thalassemia.Results:A total of 5 760 high-risk individuals were included in the screening results of thalassemia genes, and 3 868 samples of thalassemia gene mutations were detected, with a detection rate of 67.15%. Among them, there were 2 979 samples with α-thalassemia genetic mutations, with a detection rate of 51.72%; including 2 966 common genotype samples (99.56%), the main genotype was αα/-α 3.7 (20.14%, 600/2 979); 13 rare genotype samples (0.44%), 4 cases of αα/-- THAI, 3 cases of α CD40(AAG>AA-)α/αα, 2 cases of α PPα/αα, and 1 case of Fusion gene/αα, Fusion gene/α WSα, α WSα/α PPα, and α CD40(AAG>AA-)α/α WSα each. There were 340 samples with β-thalassemia gene mutations, with a detection rate of 5.90%; including 336 common genotype samples (98.82%). The β CD41/42/β N genotype was dominant (57.65%, 196/340); 4 rare genotype samples (1.18%), β CD5(-CT)/β N, β IVS-Ⅱ-2(-T)/β N, β IVS-Ⅱ-761(-T)/β N and β Initiation(ATG>AGG)/β N 1 case each. There were 549 samples of αβ-compound type thalassemia, with a detection rate of 9.53%. The α missing recombination β CD41/42 genotype was dominant (61.02%, 335/549). There were a total of 4 226 samples that could be traced back to MCV and MCH. Among them, 3 007 samples were found to have mutations in thalassemia genes through screening, 2 584 cases were found to have abnormalities in the combination of MCV and MCH indicators, and 423 samples were missed in blood routine screening, with a missed detection rate of 14.07% (423/3 007). The missed samples were mainly α static type, accounting for 89.13% (377/423) of the total missed samples. The screening sensitivity of MCV combined with MCH for α-, β- and αβ-compound type thalassemia was 82.65%, 98.07% and 98.15%, respectively. Conclusion:The types of genetic mutations in thalassemia in Sanya City are complex and diverse, and there are certain omissions in the blood routine screening of MCV combined with MCH.

Objective: To investigate the prevalence of anxiety and depression among inpatients with AIDS and its influencing factors, so as to provide the evidence for improving the psychological health among inpatients with AIDS. Methods: The inpatients with AIDS that were hospitalized in an infectious disease hospital in Chengdu City were recruited using the convenient sampling method. The demographic features, depression and anxiety were collected using a self-designed questionnaire, Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale ( SDS ), respectively, and factors affecting the development of depression and anxiety were identified using a multivariable linear regression model among inpatients with AIDS. Results: The 228 AIDS inpatients included 186 men (81.58%) and 42 women ( 18.42% ), and had a mean age of ( 48.04±16.03 ) years. There were 113 inpatients ( 49.56% ) with a CD4+T cell count of ≤200 cells/μL, and the mean SAS and SDS standardized scores were 35.87±8.01 and 42.07±11.08 among AIDS inpatients, which were both significantly greater than in normal populations ( P<0.05 ). The prevalence rates of anxiety, depression, and comorbid anxiety and depression were 5.26%, 16.23% and 4.82% among the participants, respectively. Multivariable linear regression analysis identified unemployment as a risk factor of anxiety ( β'=0.168, P<0.05 ), and CD4+T cell count as a risk factor of anxiety ( β'=-0.151, P<0.05 ) and depression ( β'=-0.238, P<0.05 ) among inpatients with AIDS. Conclusions Anxiety and depression are prevalent among inpatients with AIDS. Unemployment and a low CD4+T cell count may cause a rise in the risk of developing anxiety and depression among inpatients with AIDS.

Objective:To explore the clinical manifestations and imaging features of nocardia infection (NI) after lung transplantation and boost the diagnosis and treatment of NI.Methods:From January 2018 to December 2019, basic profiles, clinical manifestations, laboratory examinations, imaging features and treatment outcomes of 5 lung transplant recipients with a diagnosis of NF were retrospectively analyzed and summarized with the relevant literatures. There were 4 males and 1 female with a median age of 66(26-69) years. 3 patients were single-lung transplantation, 2 patients were bilateral-lung transplantation. The median time from an initial diagnosis of NI to lung transplant surgery was 6(5-19) months. Common symptoms included fever, cough with yellow phlegm and shortness of breath. Laboratory findings showed lymphopenia, significantly high C-reactive protein levels, a slight elevation of procalcitonin, hypoproteinemia and anemia. The major manifestations of high-resolution computed tomography (CT) included multiple nodules, consolidation, cavitation and pleural effusion.Results:Five strains of N. farcinica were identified from bloodstream infection ( n=2) and pulmonary infection ( n=3). After with a combined therapy of two sensitive agents, all patients improved and were discharged from hospital. During follow-ups, one patient died and the remainders were cured. Conclusions:Nocardia infection occurs in lung transplant recipients mostly within 1 year post-operation. There are non-specific symptoms and imaging features of multiple nodules and consolidation. Combination therapy of sensitive agents is indicated for lung transplant recipients with NI.

Objective:To explore the incidence, clinical characteristics and prognosis of invasive pulmonary fungal infection(IPFI)in recipients of lung transplantation(LT)in southern China.Methods:From January 2003 to August 2019, retrospective analysis was performed for 300 recipients of lung transplantation at three hospitals in southern China. There were 254 males and 46 females with an average age of (54.98±14.2)years. Clinical data were collected from medical records, including symptoms and signs, imaging studies, bronchoscopy examination, pathogen separation and culture from deep sputum and bronchoalveolar lavage fluid(BALF), fungal-related laboratory tests and tissue pathology.Results:Among 300 cases, 93(31.0%)had at least one episode of IPFI. The most common pathogen was aspergillosis(60.2%), followed by candida(15 cases, 16.1%)and Pneumocystis jeroveci (13 cases, 14.0%). Kaplan Meier analysis indicated that all-cause mortality was significantly higher in IPFI group than that in non-IPFI(nIPFI)group with one-year mortality of 45.2% vs. 26.7% in IPFI and nIPFI groups respectively( P<0.05). Conclusions:IPFI is prevalent after LT in southern China. And aspergillosis is the most common pathogen and Candida comes the next. The median occurring time for aspergillosis is 6 months after LT. Candida infection occurs earlier at airway anastomosis. A higher incidence of invasive fungal disease(IFD)associated with a lower survival indicates that IPFI has a substantial mortality among recipients after LT. Prophylactic agents should be optimized based upon an epidemiologically likely pathogen.
