Intraoperative Complications and Perioperative and Surgical Outcomes of Single-Port Robotics-Assisted Sacrocolpopexy.

INTRODUCTION AND HYPOTHESIS: The objective was to assess intraoperative and postoperative complication rates, along with perioperative and surgical outcomes, following single-port robotics-assisted sacrocolpopexy. METHODS: This retrospective case series included 200 patients who underwent single-port robotics-assisted sacrocolpopexy to treat Pelvic Organ Prolapse Quantification (POPQ) stage 2-4 symptomatic prolapse between April 2020 and August 2023 by a single surgeon. Intraoperative and postoperative complications and perioperative outcomes were evaluated for all the patients, whereas surgical outcomes for 74 patients were assessed at 1-year follow-up. Surgical failure was defined as the presence of any of the following: the presence of vaginal bulging symptoms, any prolapse beyond the hymen, or retreatment for prolapse. RESULTS: During the study period, 200 single-port robotics-assisted sacrocolpopexies were performed. The median age and body mass index were 65.0 years and 24.6 kg/m2 respectively. Most patients had POPQ stage 3 or 4 prolapse and underwent concomitant total hysterectomy. The median total operation time was 212.0 min, and none of the patients required conversion to laparoscopy or laparotomy. The intraoperative cystotomy rate was 2.5%, and one patient had a blood transfusion owing to presacral vessel injury. Postoperative complications of mesh exposure and wound hernia were 0.5% and 2.0% respectively. At 1 year postoperatively, the rate of composite surgical failure was 9.5%, with a 5.4% anatomical recurrence rate. None of the patients experienced apical prolapse recurrence, and one received anterior colporrhaphy for anterior compartment prolapse recurrence. CONCLUSIONS: Single-port robotics-assisted sacrocolpopexy is safe and effective, with low complication rates and favorable perioperative and surgical outcomes.

Changes in anti-Müllerian hormone values for ovarian reserve after minimally invasive benign ovarian cystectomy: comparison of the Da Vinci robotic systems (Xi and SP) and the laparoscopic system.

To investigate the impact on the ovarian reserve after minimally invasive ovarian cystectomy using two platforms, the Da Vinci robotic system (Xi and SP) and the laparoscopic system. Patients underwent laparoscopic or Da Vinci robotic (Xi or SP) ovarian cystectomy for benign ovarian cysts between January 1, 2018, and December 31, 2022 at Guro Hospital, Korea University Medical center. We measured the change of AMH values (%) = [(postAMH - preAMH)] × 100/preAMH. No significant differences in preoperative age, cyst size, estimated blood loss during surgery, hemoglobin drop, length of hospital stay, adhesion detachment rate and cyst rupture rate were observed. However, the operative time was significantly shorter in the laparoscopic group than that in the robotic group (67.78 ± 30.58 min vs. 105.17 ± 38.87 min, p < 0.001) The mean preAMH and postAMH were significantly higher with the Da Vinci robotic group than with the laparoscopic group (preAMH: 5.89 ± 4.81 ng/mL vs. 4.01 ± 3.59 ng/mL, p = 0.02, postAMH: 4.36 ± 3.31 ng/mL vs. 3.08 ± 2.60 ng/mL, p = 0.02). However, the mean ΔAMH was not significantly different between two groups. ΔAMH also did not demonstrate significant differences among the three groups; laparoscopic, Xi and SP robotic. Even in the patient groups with preAMH < 2 and diagnosed with endometriosis, the ΔAMH did not show significant differences between the laparoscopic and robotic groups. The Da Vinci robotic system is no inferior to conventional laparoscopic systems in preserving ovarian function.

Split genome-based retroviral replicating vectors achieve efficient gene delivery and therapeutic effect in a human glioblastoma xenograft model.

The murine leukemia virus-based semi-retroviral replicating vectors (MuLV-based sRRV) had been developed to improve safety and transgene capacity for cancer gene therapy. However, despite the apparent advantages of the sRRV, improvements in the in vivo transduction efficiency are still required to deliver therapeutic genes efficiently for clinical use. In this study, we established a gibbon ape leukemia virus (GaLV) envelopepseudotyped semi-replication-competent retrovirus vector system (spRRV) which is composed of two transcomplementing replication-defective retroviral vectors termed MuLV-Gag-Pol and GaLV-Env. We found that the spRRV shows considerable improvement in efficiencies of gene transfer and spreading in both human glioblastoma cells and pre-established human glioblastoma mouse model compared with an sRRV system. When treated with ganciclovir after intratumoral injection of each vector system into pre-established U-87 MG glioblastomas, the group of mice injected with spRRV expressing the herpes simplex virus type 1-thymidine kinase (HSV1-tk) gene showed a survival rate of 100% for more than 150 days, but all control groups of mice (HSV1-tk/PBS-treated and GFP/GCV-treated groups) died within 45 days after tumor injection. In conclusion, these findings sug-gest that intratumoral delivery of the HSV1-tk gene by the spRRV system is worthy of development in clinical trials for the treatment of malignant solid tumors.

Water extract of Artemisia scoparia Waldst. & Kitam suppresses LPS-induced cytokine production and NLRP3 inflammasome activation in macrophages and alleviates carrageenan-induced acute inflammation in mice.

ETHNOPHARMACOLOGICAL RELEVANCE: Artemisia scoparia Waldst. & Kitam (A. scoparia) is a perennial herbal plant that is widely used as a folk remedy in Asian countries. Several studies have demonstrated that A. scoparia has various physiological effects, including anti-inflammation, anti-hypertension, anti-obesity, anti-hepatotoxicity, and anti-oxidant effects. AIM OF THE STUDY: The objective of the present study was to examine the anti-inflammatory effects of water extract of A. scoparia (WAS). MATERIALS AND METHODS: Murine bone marrow-derived macrophages (BMDMs), human monocyte THP-1 and murine fibroblast 3T3-L1 cells were used for the in vitro experiments. Cell viability and cytokine production were determined by the MTT assay and ELISA, respectively. RT-PCR was performed to determine iNOS gene expression and the Griess reaction was used to measure nitrite levels. iNOS protein expression, activation of NF-κB and MAPKs, and cleavage of caspase-1 and IL-1ß were determined by Western blot analysis. A carrageenan-induced mouse model of acute inflammation was used in the in vivo experiments. RESULTS: Pretreatment with WAS concentration-dependently suppressed gene expression and IL-6, TNF-α, CXCL1 and iNOS protein levels in BMDMs stimulated with LPS. In addition, pretreatment with WAS inhibited LPS-induced production of IL-6 and TNF-α in THP-1 cells and CXCL1 in 3T3-L1. Furthermore, LPS induced phosphorylation of p65 in BMDMs, and this induction was dramatically suppressed by WAS pretreatment. We further investigated whether WAS regulates activation of the NLRP3 inflammasome, which is known to be essential for IL-1ß processing. WAS inhibited the production of IL-1ß, but not IL-6, in response to adenosine triphosphate (ATP) and monosodium uric acid (MSU) crystals in LPS-primed BMDMs. Cleavage of caspase-1 and IL-1ß was also reduced by WAS. We finally evaluated the in vivo anti-inflammatory effects of WAS in a mouse model of carrageenan-induced acute inflammation. Subcutaneous administration of WAS reduced production of the inflammatory cytokines IL-6, TNF-α, CXCL1, and IL-1ß. Recruitment of immune cells, mostly neutrophils, was also reduced by administration of WAS. Infiltration of inflammatory cells and edema in the submucosa of air pouch tissues were markedly improved in the WAS-treated groups. CONCLUSIONS: Our results indicate that WAS possesses potent anti-inflammatory properties. These findings suggest that A. scoparia is a candidate functional food targeting several inflammatory diseases.

Optical and Fluorescent Dual Sensing of Aminoalcohols by in Situ Generation of BODIPY-like Chromophore.

A novel multifunctional aminophenylboronic acid connected to a diphenylketone gives both circular dichroism and fluorescence signals by in situ generation of a BODIPY-like chromophore in the presence of aminoalcohols. DFT calculations were used to understand the role of each functional group in the mechanism. This new sensor can distinguish different aminoalcohols and quantitatively indicate the concentration of the substrate, allowing for the convenient determination of the ee of racemic mixtures with a single probe.

Meta-analysis about cognitive intervention effect applied to dementia patients.

OBJECTIVE: The study tries to explore what effects multiple cognitive intervention, computer-based intervention, and memory training program had on dementia patients through meta-analysis. METHOD: Data was collected using an overseas search engine and 13 pieces of research published from January 2001 to April 2015 were selected. On papers that fit the selection criteria qualitative evaluation was conducted using Jadad evaluation and using pre-post average, standard deviation, and sample size of cognitive function, meta-analysis was conducted. RESULTS: The 13 studies selected included 6 multiple interventions, 4 computer-based interventions, and 3 memory training programs. In the Jadad evaluation all had 3 points or higher and there were 474 research participants and in the result of effect size analysis memory training intervention was found to be 'large effect size', computer-based intervention 'medium effect size', and multiple cognitive intervention 'small effect size'. All three intervention methods were all statistically significant (p < 0.05). CONCLUSION: It was found that the effect on dementia patients was in the order of memory training intervention, computer-based intervention, and multiple cognitive intervention. Clinically, this can be objective basis for treatment method for cognitive intervention of dementia patients.
