Comparison of the short-term and long-term outcomes of laparoscopic hysterectomies and of abdominal hysterectomies: a case study of 4,895 patients in the Guangxi Zhuang Autonomous Region, China.

BACKGROUND: To evaluate the short-term and long-term outcomes after laparoscopic hysterectomy (LH) compared with abdominal hysterectomy (AH) in case of benign gynecological disease. METHODS: A multi-center cohort retrospective comparative study of population among 4,895 hysterectomies (3,539 LH vs.1,356 AH) between 2007 and 2013 was involved. Operative time (OT), estimated blood loss (EBL), intra-operative and post-operative complications, passing flatus; days with indwelling catheter, questionnaires covering pelvic floor functions and sexual functions were assessed. RESULTS: The EBL (174.1±157.4 vs. 263.1±183.2 cc, LH and AH groups, respectively), passing flatus (38.7±14.1 vs. 48.1±13.2 hours), days with indwelling catheter (1.5±0.6 vs. 2.2±0.8 days), use of analgesics (6.5% vs. 73.1%), intra-operative complication rate (2.4% vs. 4.1%), post-operative complication rate (2.3% vs. 5.7%), post-operative constipation (12.1% vs. 24.6%), mild and serious stress urinary incontinence (SUI) post-operative (P<0.001; P=0.014), and proportion of Female Sexual Functioning Index (FSFI) total score <26.55 post-operative (P<0.001) of the LH group were significantly less than those of AH group. There were no significant differences in OT (106.5±34.5 vs. 106.2±40.3 min) between the two groups. CONCLUSIONS: LH is a safe and efficient operation for improving patients?long-term quality of life (QoL), and LH is a cost-effectiveness procedure for treating benign gynecological disease. LH is superior to AH due to reduced EBL, reduced post-operative pain and earlier passing flatus.

Effects of self-help mindfulness-based cognitive therapy on mindfulness, symptom change, and suicidal ideation in patients with depression: a randomized controlled study.

Objective: This study aimed to evaluate the effects of self-help mindfulness-based cognitive therapy (MBCT-SH) on mindfulness, symptom change, and suicidal ideation in patients with depression. Methods: For this randomized controlled study, 97 patients were randomly assigned to either the MBCT-SH (n = 48) or control (n = 49) group. The Five Facet Mindfulness Questionnaire (FFMQ), Hamilton Depression Rating Scale (HAMD-24), and Suicide Attitude Questionnaire (SAQ) were used to assess mindfulness, depression symptoms, and suicidal ideation, respectively, at baseline (T0), intervention week 4 (T1), intervention week 8 (T2), and 3-month follow-up (T3). The groups were also compared on treatment costs and readmission rates at a 6-month follow-up. Results: In the MBCT-SH group, 46 of 48 participants (96%) completed the eight-week program. At T0, there were no statistically significant between-group differences in demographics, clinical characteristics, FFMQ, HAMD-24, or SAQ. Nor were there statistically significant differences on the HAMD-24 or SAQ between the MBCT-SH and control groups at T1 (p = 0.18 and p = 0.59, respectively), while mindfulness was significantly higher in the MBCT-SH group (t = 2.383, p = 0.019). At T2, there were significant between-group differences on the FFMQ, HAMD-24, and SAQ, all of which remained significant at T3. At the 6-month follow-up, per capita treatment costs were 5,298 RMB lower in the MBCT-SH group compared with the control group, while their readmission rates (6.1% and 4.2%, respectively) did not differ significantly. Conclusion: These findings support the feasibility and effectiveness of MBCT-SH among patients with depression. Clinical trial registration: http://www.chictr.org.cn, ChiCTR2300077850.

Immune landscape in rejection of renal transplantation revealed by high-throughput single-cell RNA sequencing.

Background: The role of the cellular level in kidney transplant rejection is unclear, and single-cell RNA sequencing (scRNA-seq) can reveal the single-cell landscape behind rejection of human kidney allografts at the single-cell level. Methods: High-quality transcriptomes were generated from scRNA-seq data from five human kidney transplantation biopsy cores. Cluster analysis was performed on the scRNA-seq data by known cell marker genes in order to identify different cell types. In addition, pathways, pseudotime developmental trajectories and transcriptional regulatory networks involved in different cell subpopulations were explored. Next, we systematically analyzed the scoring of gene sets regarding single-cell expression profiles based on biological processes associated with oxidative stress. Results: We obtained 81,139 single cells by scRNA-seq from kidney transplant tissue biopsies of three antibody-mediated rejection (ABMR) patients and two acute kidney injury (AKI) patients with non-rejection causes and identified 11 cell types, including immune cells, renal cells and several stromal cells. Immune cells such as macrophages showed inflammatory activation and antigen presentation and complement signaling, especially in rejection where some subpopulations of cells specifically expressed in rejection showed specific pro-inflammatory responses. In addition, patients with rejection are characterized by an increased number of fibroblasts, and further analysis of subpopulations of fibroblasts revealed their involvement in inflammatory and fibrosis-related pathways leading to increased renal rejection and fibrosis. Notably, the gene set score for response to oxidative stress was higher in patients with rejection. Conclusion: Insight into histological differences in kidney transplant patients with or without rejection was gained by assessing differences in cellular levels at single-cell resolution. In conclusion, we applied scRNA-seq to rejection after renal transplantation to deconstruct its heterogeneity and identify new targets for personalized therapeutic approaches.

Evaluation and Use of Organs from Donors Poisoned by Organophosphorus Pesticide.

BACKGROUND The aim of this study was to explore the evaluation and use of donor organs from donors with brain death caused by acute severe organophosphorus pesticides and provide a basis for the use of such donor organs. MATERIAL AND METHODS Seven cases of brain dead donors caused by acute organophosphorus pesticide poisoning from January 2014 to December 2018 in the hospital were collected, and a retrospective analysis was made of the donors' age, race, physiological and pathological changes, donor organ function changes and the organ use, liver or kidney function recovery, and complications of the recipients. The 18 recipients were followed up until June 31, 2022. RESULTS We found that 71.42% of organ donors were male, and 71.42% of organ donors were under 50 years old. The main cause of death was respiratory failure caused by organophosphorus pesticide poisoning. The liver and kidney functions of 7 donors were damaged, and 3 livers could not be used due to severe functional damage, but the liver or kidney function of 18 recipients gradually recovered after transplantation. Delayed recovery of graft function occurred after transplantation accounted for 21.43%, and the grafts had good short-term to medium-term performance. CONCLUSIONS Although the function of organs from donor with brain death due to acute severe organophosphorus pesticide poisoning is seriously damaged, most of the organs can still be used for transplantation. Individualized functional maintenance according to the situation of donors is conducive to improving the quality of organs.

[Constitutive characteristics and change trend of gynecological malignant tumors in 8009 hospitalized patients in Guangxi Zhuang Autonomous Region].

OBJECTIVE: To investigate the constitutive characteristics and the change trend of gynecologic malignant tumors in hospitalized patients in Guangxi Zhuang Autonomous Region over the recent 20 years. METHODS: Clinical data of 8009 in-patients who suffered from gynecologic malignant tumors in 23 hospitals from 1985 to 2004 in Guangxi Zhuang Autonomous Region were analyzed, with respect to the tumor types and change trend. RESULTS: (1) The leading 4 types of malignant tumors were cervical cancers, ovarian cancers, endometrial cancers, and malignant trophoblastic tumors according to the constitutive ratios of the tumors. The constitutive ratio of cervical cancer patients rose year by year, from 17.48% during the 1985-1989 period to 49.25% during the 2000-2004 period (P < 0.01). While the constitutive ratio of malignant trophoblastic tumors dropped year by year. The changes of ovarian cancer, endometrial cancer, vulvar and vaginal carcinomas, and sarcoma of the uterus were not obvious (P > 0.05). (2) The occurring age of cervical cancers became younger obviously, from > or = 60 years old dropped to < 40 years old. (3) Cervical cancers were found mainly in urban residents in the former 10 years, the constitutive ratio being 67.1%; while in the latter 10 years it gradually shifted to rural residents, accounting for 52.6% of the total gynecological tumors. (4) Patients were usually at stages II, III, IV when they visited a doctor for their diseases. Especially for ovarian cancer, malignant trophoblastic tumors, sarcoma of the uterus, these patients were in the intermediate or advanced stage when they were diagnosed, mainly because of lack of obvious symptoms. The constitutive ratio of these advanced patients was over 60%. CONCLUSIONS: We should strengthen the screening program of cervical cancer, and pay more attention to prevention and control of other gynecological reproductive organ tumors at the same time. On the other hand, we should explore better tumor markers, new methods of diagnosis and treatment to improve early diagnosis and treatment of gynecologic malignant tumors.

Aim. Our aim is to survey the treatment effect of PEG-IFN plus ribavirin in patients infected with HCV genotype 6a in Guangdong and Guangxi province of China and investigate best course of antiviral treatment for patients with HCV-6a infection. Methods. 515 eligible patients received subcutaneous 180 µg PEG-IFNα-2a or 1.5 µg/kg PEG-IFNα-2b once weekly plus oral ribavirin. Primary outcome was SVR by intention-to-treat analysis. Secondary outcome was RVR, cEVR, ETR, and relapse rate. Results. SVR in patients with HCV-6a infection treated for 48 weeks was comparable to that in patients with HCV-2/3 infection (80.9% versus 82.5%, p = 0.812) and higher than that in patients with HCV-1b infection (80.9% versus 67.2%, p = 0.014). ETR (98.9% versus 90.6%, p = 0.016), virological response at month 3 of end-of- treatment (88.8% versus 76.6%, p = 0.044), SVR (80.9% versus 65.6%, p = 0.032), and virological response at month 12 of end-of-treatment (76.4% versus 60.9%, p = 0.04) in patients with HCV-6a infection treated for 48 weeks were higher than those in patients with HCV-6a infection treated for 24 weeks. Conclusion. SVR in patients with HCV-6a treated for 48 weeks was comparable to that in patients with HCV-2/3 infection and higher than that in patients with HCV-1b infection; patients with HCV-6a infection treated for 48 weeks had a superior treatment response than patients treated for 24 weeks.
