The role of adjuvant chemotherapy after radical surgery in patients with lymph node-positive bladder cancer or locally advanced (pT3, pT4a) bladder cancer: A meta-analysis and systematic review.

PURPOSE: This study aims to evaluate the impact of adjuvant chemotherapy (AC) on survival outcomes in patients with lymph node-positive bladder cancer or locally advanced (pT3, pT4a) bladder cancer after surgery. We also seek to identify which patients with pN+ bladder cancer are most likely to benefit from AC after radical cystectomy (RC). METHODS: We searched databases including Embase, PubMed, Cochrane, and ClinicalTrials.gov to identify relevant literature published in English up to February 2024. We used Stata to compare various parameters. The study has been registered in PROSPERO. RESULTS: A total of 21 studies were analyzed, including 1 randomized controlled trial, 6 prospective studies, and 14 retrospective studies, encompassing 12,888 patients. The meta-analysis showed that for patients with lymph node-positive bladder cancer, the adjuvant chemotherapy (AC) group had higher overall survival (OS) (I2=58.2%, HR 0.69; 95% CI: 0.57-0.83; P=0.019) and recurrence-free survival (RFS) (I2=66.6%, HR 0.71; 95% CI: 0.57-0.89; P=0.006) compared to the radical cystectomy (RC) group. For patients with pT3 and pT4a bladder cancer, the AC group had higher overall survival (OS) (I2=57.3%, HR 0.77; 95% CI: 0.67-0.89; P=0.022) and cancer-specific survival (CSS) (I2=47.2%, HR 0.75; 95% CI: 0.64-0.88; P=0.0048) compared to the RC group. At the same time, according to the different chemotherapy regimens, we divided the cisplatin-based chemotherapy regimen and carboplatin based chemotherapy or other regimens into two subgroups for analysis, and found that the OS (I2=41.4%, HR 0.64; 95%CI: 0.51~0.80; P=0.000) was better than carboplatin and other chemotherapy regimens (I2=64.1%, HR 0.77; 95%CI: 069~0.86; P=0.000); Lymph node density (LND) was found to be an independent predictor of overall survival (HR=1.6; 95% CI: 1.31-1.95; P=0.0000). CONCLUSION: This study found that postoperative adjuvant chemotherapy (AC) improves overall survival (OS), cancer-specific survival (CSS), and recurrence-free survival (RFS) in patients with pT3, pT4a, It was also confirmed that cisplatin-based chemotherapy regimen was more beneficial for patients with bladder cancer; and lymph node-positive bladder cancer. Additionally, our analysis revealed that patients with lymph node-positive bladder cancer benefit more from postoperative AC. It was further demonstrated that cisplatin-based chemotherapy regimens are more beneficial than other regimens for patients with locally advanced bladder cancer.

Comparative analysis of perioperative outcomes in obese patients undergoing robot-assisted radical prostatectomy (RARP) versus open radical prostatectomy (ORP): a systematic review and meta-analysis.

The purpose of this study was to conduct a comparative analysis of the perioperative outcomes associated with robot-assisted laparoscopic prostatectomy (RARP) versus open radical prostatectomy (ORP) in the obese population diagnosed with prostate cancer. We performed a comprehensive search in key databases such as PubMed, Embase, Web of Science, and the Cochrane Library, encompassing studies of all languages, with a final search date of April 2024. We also omitted articles that consisted of conference abstracts and content that was not pertinent to our study. The aggregated outcomes were evaluated utilizing the metrics of weighted mean differences (WMDs) and odds ratios (ORs). A sensitivity analysis was also integrated into our assessment. The meta-analysis was facilitated by employing Stata/MP version 18 software. Additionally, the study was duly registered with PROSPERO under the identifier: CRD 42024540216. This meta-analysis, which included five trials, shows that compared to ORP, RARP is associated with a reduced estimated blood loss (EBL) (WMD -445.77, 95%CI -866.08, -25.45; p = 0.038), a decreased transfusion rate (OR 0.17, 95%CI 0.13, 0.21; p < 0.001), and a diminished overall complication rate (OR 0.71, 95%CI 0.58, 0.86; p = 0.001). No statistically significant differences were found in operative time (OT) (WMD 1.88, 95%CI -46.53, 50.28; p = 0.939) or length of stay (LOS) (WMD -0.41, 95%CI -1.07, 0.25; p = 0.221). Among patients with obesity and prostate cancer, RARP demonstrates advantages over ORP by reducing estimated blood loss, transfusion requirements, and the incidence of complications. Notably, there were no significant differences in operative duration and hospital stay between the two surgical approaches. These findings suggest that RARP could be a preferable surgical option for obese individuals with prostate cancer.

A systematic review and meta-analysis of the role of perineal hydrodissection in perioperative, oncologic, and functional outcomes for patients undergoing robot-assisted radical prostatectomy.

This study aims to compare the perioperative, oncological, and functional outcomes of perineal hydrodissection (HD) with standard treatment (ST) in patients undergoing robot-assisted radical prostatectomy. We performed an exhaustive search in databases such as PubMed, Embase, Web of Science, and the Cochrane Library, seeking English-language studies relevant to our research question, with a cutoff date of April 2024. The pooled results were assessed using the weighted mean differences (WMDs), standardized mean differences (SMDs), and odds ratios (ORs) metrics. We also performed a sensitivity analysis. The meta-analysis was conducted utilizing Stata/MP version 18 software. The study was registered with PROSPERO (ID: CRD 42024536400). We included a total of five studies (three RCTs and two retrospective studies). According to the data from the Meta-analysis, the HD group showed positive effects in promoting urinary continence (OR 2.64, 95% CI 1.36, 5.12; p = 0.004 < 0.05) and erectile function (SMD 0.92, 95%CI 0.56, 1.27; p < 0.05) within 3 months after surgery. However, no notable disparities were observed in terms of operative time, estimated blood loss, bilateral nerve-sparing rate, or the rate of positive surgical margin. Perineal hydrodissection can be safely applied in robot-assisted radical prostatectomy (RARP), offering a distinct advantage in functional outcomes compared to those who undergo standard robot-assisted prostatectomy alone.

Efficacy and safety of transurethral thulium laser enucleation versus robot-assisted prostatectomy for large-volume benign prostatic hyperplasia: a systematic review and meta-analysis.

To compare perioperative outcomes between Holmium laser enucleation of the prostate (HoLEP) and robotic-assisted simple pasta-ectomy (RASP)for large-volume benign prostatic hyperplasia(> 80 ml). In August 2023, we undertook a comprehensive search of major global databases including PubMed, Embase, and Google Scholar, focusing solely on articles written in English. Studies that were merely reviews or protocols without any specific published data were omitted. Furthermore, articles that comprised conference abstracts or content not pertinent to our subject of study were also disregarded. To calculate the inverse variances and 95% confidence intervals (CIs) for categorical variables' mean differences, we employed the Cochran-Mantel-Haenszel approach along with random-effects models. The findings were denoted in the form of odds ratios (ORs) and 95% CIs. A p-value less than 0.05 was deemed to indicate statistical significance. Our finalized meta-analysis incorporated six articles, including one randomized controlled trial (RCT) and five cohort studies. These studies accounted for a total of 1218 patients, 944 of whom underwent Holmium Laser Enucleation of the Prostate (HoLEP) and 274 who underwent Robotic-Assisted Simple Prostatectomy (RASP). The pooled analysis from these six papers demonstrated that compared to RASP, HoLEP had a shorter hospital stay, shorter catheterization duration, and a lower blood transfusion rate. Moreover, HoLEP patients exhibited a smaller reduction in postoperative hemoglobin levels. Statistically, there were no significant differences between the two procedures regarding operative time, postoperative PSA, the weight of prostate specimens, IPSS, Qmax, PVR, QoL, and postoperative complications. (HoLEP) and (RASP) are both effective and safe procedures for treating large-volume benign prostatic hyperplasia. HoLEP, with its benefits of shorter catheterization and hospitalization duration, lesser decline in postoperative hemoglobin, and reduced blood transfusion needs, stands as a preferred choice for treating extensive prostate enlargement. However, further validation through more high-quality clinical randomized trials is required.

Cardiovascular Adverse Events Associated With New-Generation Androgen Receptor Pathway Inhibitors (ARPI) for Prostate Cancer: A Disproportionality Analysis Based on the FDA Adverse Event Reporting System (FAERS).

BACKGROUND: The potential cardiovascular adverse events associated with new-generation androgen receptor pathway inhibitors (ARPI) in the treatment of prostate cancer remain unclear. We aimed to assess the pharmacovigilance (PV), reporting rate, severity, and reaction outcomes of major adverse cardiovascular events (MACE) related to new-generation ARPI for prostate cancer reported to the United States Food and Drug Administration Adverse Event Reporting System (FAERS). METHODS: We analyzed reports of cardiovascular adverse events associated with drug therapy for prostate cancer submitted to FAERS between January 2014 and December 2022. Three primary new-generation ARPIs were identified: abiraterone acetate, enzalutamide, and apalutamide. Our primary composite endpoint was the PV of MACE caused by ARPIs in the treatment of prostate cancer, and the secondary endpoint was PV of other cardiovascular events. The software implemented was STATA 17.0 MP. RESULTS: A total of 278,031 suspected drug-adverse event pairs related to drug treatment in patients with prostate cancer were identified, of which 10,861 reports were cardiovascular events, including 5800 reports of MACE and 5061 reports of other cardiovascular events. The majority of these cardiovascular adverse event reports came from the United States (36.6%) and were mostly older men (age 76.0 ± 8.6 years). Compared with enzalutamide, the constituent ratio of MACE caused by abiraterone acetate and apalutamide was significantly increased, but the incidence of severe MACE decreased significantly. The PV signal regarding MACE was detected in abiraterone acetate and apalutamide but not in enzalutamide. CONCLUSION: Abiraterone acetate and apalutamide presumably are associated with a higher risk of MACE than enzalutamide in new-generation ARPI for prostate cancer. More extensive prospective studies and more extended follow-up periods need to confirm this further.

Perioperative, functional, and oncologic outcomes after ablation or partial nephrectomy for solitary renal tumors: a systematic review and meta-analysis of comparative trials.

Objectives: The perioperative, functional, and oncological outcomes of patients with solitary small renal tumors (SRMs) treated with ablation (AT) or partial nephrectomy (PN) remain controversial. The aim of this study was to compare the outcomes of these two surgical techniques. Methods: In April 2023, we conducted a literature search in several widely used databases worldwide, including PubMed, Embase, and Google Scholar. Review Manager was used to compare various parameters. The study was registered with PROSPERO (CRD42022377157). Results: Our final meta-analysis included 13 cohort studies with a total of 2,107 patients. Compared to partial nephrectomy (PN), ablation (AT) had shorter hospital stays (WMD -2.37 days, 95% CI -3.05 to -1.69; p < 0.00001), shorter operating times (WMD -57.06 min, 95% CI -88.92 to -25.19; p = 0.0004), less postoperative creatinine increases (WMD -0.17 mg/dL, 95% CI -0.29 to -0.05; p = 0.006), less postoperative glomerular filtration rate decreases (WMD -9.84 mL/min/1.73 m2, 95% CI -14.25 to -5.44; p < 0.0001), less postoperative new-onset chronic kidney disease (OR 0.33, 95% CI 0.16 to 0.71; p = 0.005), and less intraoperative blood loss (WMD -285.92 ml, 95% CI -428.44 to -143.40; p < 0.0001). The transfusion rate was lower in the ablation group (OR 0.17, 95% CI 0.06 to 0.51; p = 0.001). The risk of local recurrence was higher in the ablation group (OR 2.96, 95% CI 1.27 to 6.89; p = 0.01), while the risk of distant metastasis was higher in the partial nephrectomy group (OR 2.81, 95% CI 1.28 to 6.18; p = 0.01). The intraoperative and postoperative complication rates were lower in the ablation group (OR 0.23, 95% CI 0.08 to 0.62; p = 0.004 and OR 0.21, 95% CI 0.11 to 0.38; p < 0.00001, respectively). However, overall survival, postoperative dialysis rate, and tumor-specific survival were not different between the two groups. Conclusions: Our data suggest that ablation and partial nephrectomy are equally safe and effective in the treatment of small solitary kidney tumors and are better options for patients with poor preoperative physical condition or poor renal function.

A systematic review and meta-analysis of outcomes between dusting and fragmentation in retrograde intrarenal surgery.

OBJECTIVES: Comparing stone-free rates and associated outcome measures between two surgical modalities of lithotripsy fragmentation and removal or spontaneous passage of dust during retrograde intrarenal surgery (RIRS). METHODS: In March 2023, we conducted a literature search in several widely used databases worldwide, including PubMed, Embase, and Google Scholar. We only considered English articles and excluded pediatric patients. Reviews and protocols without any published data were excluded. We also excluded articles with conference abstracts and irrelevant content. We used the Cochran-Mantel-Haenszel method and random-effects models to assess inverse variances and 95% confidence intervals (CIs) for mean differences in categorical variables. The results were reported as odds ratios (ORs) and 95% CIs. Statistical significance was set at p < 0.05. RESULTS: Our final meta-analysis included nine articles, comprising two randomized controlled trials (RCTs) and seven cohort studies. The total number of patients included in these studies was 1326, and all studies used holmium laser lithotripsy. The pooled analysis of the dust and fragmentation groups showed that the fragmentation group had a higher stone-free rate (OR 0.6; 95% CI 0.41 - 0.89; p = 0.01); the dust group had a shorter operative time (WMD - 11.6 min; 95% CI - 19.56 - -3.63; p = 0.004); and the dust group had a higher retreatment rate (OR 2.03; 95% CI 1.31 - 3.13; p = 0.001). There was no statistically significant difference between the two groups in terms of length of hospital stay, overall complications, or postoperative fever. CONCLUSIONS: Our results showed that both procedures could be safely and effectively used for upper ureteral and renal calculi lithotripsy, the dust group had potential advantages over the fragmentation group in terms of the operation time, and the fragmentation group had certain advantages in terms of stone-free rate and retreatment rate.

Erectile function, urinary continence and oncologic outcomes of neurovascular bundle sparing robot-assisted radical prostatectomy for high-risk prostate cancer: A systematic review and meta-analysis.

Background: The nerve-sparing (NS) effect of robot-assisted radical prostatectomy (RARP) on patients with a high-risk prostate cancer remains unclear. The objective of this study was to compare the urinary continence, erectile function and oncology outcomes of the nerve-sparing and non-nerve-sparing (NNS) group during RARP surgeries. Methods: We systematically searched databases including PubMed, Embase, Cochrane Library and Web of Science to identify relevant studies published in English up to December 2022. Newcastle-Ottawa Scale (NOS) was used as a quality evaluation tool to evaluate the quality of the literature parameters involved, including urinary continence, erectile function and oncologic outcomes, which were compared using the Stata 15.1 software (StataSE, USA). Results: A total of 8 cohort studies involving 2499 patients were included. A meta-analysis of results showed that the NS group was beneficial to the recovery of urinary continence (RR 0.46, 95%CI 0.22, 0.96; p=0.045<0.05) and erectile function (RR 0.32, 95%CI 0.16, 0.63; p=0.001<0.05) 12 months after surgeries, which showed a better oncological outcome (RR 1.31, 95%CI 1.01, 1.69; p=0.01<0.05). Conclusions: The current study results indicate that intraoperative NS during RARP is beneficial to long-term postoperative functional recovery and tumor prognosis of patients with high-risk prostate cancers. Due to interstudy interferences, the results should be interpreted with caution. Systematic review registration: https://www.crd.york.ac.uk/PROSPERO/, identifier: CRD42022384647.

Perioperative, functional, and oncologic outcomes in patients undergoing robot-assisted radical prostatectomy previous transurethral resection of prostate: a systematic review and meta-analysis of comparative trials.

The influence of robot-assisted radical prostatectomy (RARP) on patients who have previously undergone transurethral resection of the prostate (TURP) versus TURP-naive patients is still debatable. The present study aimed to compare perioperative, functional, and oncologic outcomes of RARP between TURP and Non-TURP groups. We systematically searched the databases such as Science, PubMed, Embase, Web of Science, and the Cochrane Library database to identify relevant studies published in English up to August 2022. Review Manager was used to compare various parameters. The study was registered with PROSPERO (CRD42022378126). Eight comparative trials with a total of 4186 participants were conducted. The TURP group had a longer operative time (WMD 22.22 min, 95% CI 8.48, 35.95; p = 0.002), a longer catheterization time (WMD 1.32 day, 95% CI 0.37, 2.26; p = 0.006), a higher estimated blood loss (WMD 23.86 mL, 95% CI 2.81, 44.90; p = 0.03), and higher bladder neck reconstruction rate (OR 8.02, 95% CI 3.07, 20.93; p < 0.0001). Moreover, the positive surgical margin (PSM) was higher in the TURP group (OR 1.49, 95% CI 1.12, 1.98 p = 0.007). However, there was no difference between the two groups regarding the length of hospital stay, transfusion rates, nerve-sparing status, complication rates, long-term continence, potency rates and biochemical recurrence (BCR). Performing RARP on patients who have previously undergone TURP is a safe procedure. Furthermore, the current findings demonstrated that the TURP group had comparable oncologic and long-term functional outcomes to the Non-TURP group.

OBJECTIVES: To establish a system for regulating the gene expression of embryonic mouse cerebral cortex neural stem cells (NSCs) using in utero electroporation (IUE). METHODS: At embryonic day 14.5, the mouse cerebral cortex NSCs were electro-transfected with the pCIG plasmid injected into the ventricle of the mouse embryo. At embryonic day 16.5 or day 17.5, embryonic mouse brain tissues were collected to prepare frozen sections. Immunofluorescence staining was used to observe the proliferation, apoptosis, division, directional differentiation, migration, and maturation of NSCs. RESULTS: The differentiation of NSCs into intermediate progenitors, the proliferation and apoptosis of NSCs, and the morphological development of radial axis of radial glial cells were observed at embryonic day 16.5. The differentiation of NSCs into neurons in layers V-VI of the cerebral cortex, the migration of NSCs to the lateral cerebral cortex, the development of dendrites of migrating neurons, and the maturation of neurons were observed at embryonic day 17.5. CONCLUSIONS: The system for regulating the gene expression of embryonic mouse cerebral cortex NSCs can be established using IUE, which is useful for the study of neural development related to the proliferation, apoptosis, division, directional differentiation, migration and maturation of NSCs in the cerebral cortex.

Flip-over of blood vessel intima caused by vascular closure device: A case report.

BACKGROUND: Complications of vascular closure devices mainly include bleeding, vascular injury, and trapped device that cannot be removed percutaneously. However, arterial stenosis or occlusion induced by vascular injury is rare. This article introduces a rare case with severe acute limb ischemia after using the vascular closure device (StarClose). CASE SUMMARY: A 54-year-old man was admitted because of necrosis of the second toe of the left foot for 2 mo. Ultrasound showed left femoral artery stenosis, and occlusion of the left popliteal, posterior tibial, peroneal, anterior tibial and dorsalis pedis arteries, suggesting arteriosclerosis obliterans of low extremities, gangrene and type 2 diabetes. He underwent an interventional procedure of drug-eluting balloon in the left lower limb via antegrade puncture of the left common femoral artery. He developed acute limb ischemia after 1 h, and severe pain, numbness, pale skin, low skin temperature and weakened sensation in the left foot. Injury of the common femoral artery intima was considered. Exploratory surgery showed occlusion at the puncture point accompanied with bulged vascular lumen and flipped vascular intima caused by StarClose. The flipped intima was removed. The limb blood supply was restored and the limb was saved post-surgery. He recovered well at final follow-up. CONCLUSION: Incorrect use of the vascular closure device was the main cause of severe acute limb ischemia in this case.

The Effect of Antioxidants on Sperm Quality Parameters and Pregnancy Rates for Idiopathic Male Infertility: A Network Meta-Analysis of Randomized Controlled Trials.

Purpose: Male infertility is a global public health issue recognized by the WHO. Recently, antioxidants are increasingly used to treat idiopathic male infertility. However, the lack of available evidence has led to the inability to rank the effects of antioxidants on the sperm quality parameters and pregnancy rate of infertile men. This network meta-analysis studied the effects of different antioxidants on the sperm quality and pregnancy rate of idiopathic male infertility. Methods: We searched PubMed, Embase, Web of Science, and Cochrane Library databases for randomized controlled trials (RCTs). The weighted mean difference (WMD) and odds ratio (OR) were applied for the comparison of continuous and dichotomous variables, respectively, with 95% CIs. The outcomes were sperm motility, sperm concentration, sperm morphology, and pregnancy rate. Results: A total of 23 RCTs with 1,917 patients and 10 kids of antioxidants were included. l-Carnitine, l-carnitine+l-acetylcarnitine, coenzyme-Q10, ω-3 fatty acid, and selenium were more efficacious than placebo in sperm quality parameters. l-Carnitine was ranked first in sperm motility and sperm morphology (WMD 6.52% [95% CI: 2.55% to 10.05%], WMD 4.96% [0.20% to 9.73%]). ω-3 fatty acid was ranked first in sperm concentration (WMD 9.89 × 106/ml, [95% CI: 7.01 to 12.77 × 106/ml]). In terms of pregnancy rate, there was no significant effect as compared with placebo. Conclusions: l-Carnitine was ranked first in sperm motility and sperm morphology. ω-3 fatty acid was ranked first in sperm concentration. Coenzyme-Q10 had better effective treatment on sperm motility and concentration. Furthermore, high-quality RCTs with adequate sample sizes should be conducted to compare the outcomes of different antioxidants.

Identification of lncRNA-mRNA regulatory network associated with isolated systolic hypertension and atherosclerotic cerebral infarction.

BACKGROUND: Increasingly, evidence has shown that long non-coding RNAs (lncRNAs) play an important role in isolated systolic hypertension (ISH). However, a systematic lncRNA-messenger RNA (mRNA) regulatory network is still absent in isolated systolic hypertension and atherosclerotic cerebral infarction patients (ISH & ACI). This research aimed to establish a lncRNA-mRNA co-expression network in patients with ISH & ACI, to probe into the potential functions of lncRNA in such patients. METHODS: Expression profiles of lncRNA and mRNAs were collected and compared, from 8 patients with ISH and 8 patients with ISH & ACI by RNA-seq data. Differentially expressed lncRNAs and mRNAs were screened out via high-throughput sequencing in the plasma of ISH/ACI patients and control ISH patients. Then, a lncRNA-mRNA interaction network was built using the Pearson correlation coefficient by Cytoscape software. The expression levels of the hub genes and lncRNAs were verified by quantitative reverse transcription-polymerase chain reaction (qRT-PCR) in another 10 ISH/ACI patients and 10 control patients. This study was approved by the responsible institutional review board (IRB) and informed consent was provided by participants. RESULTS: A total of 2,768 differentially expressed lncRNAs and 747 differentially expressed mRNAs were identified. We identified two hub genes (CD226 and PARVB) and 11 lncRNAs in the lncRNA-mRNA interaction network. The results of qRT-PCR and cell assay verified that lncRNAs ENST00000590604 and CD226 are highly expressed in patients of ISH & ACI. Further, CD226 was associated with vascular endothelial cells growth and stability through the platelet activation and focal adhesion pathway. CONCLUSIONS: We established a novel mRNA-lncRNA interaction network. The lncRNAs ENST00000590604 and CD226 might be the potential biomarkers of ISH & ACI.

Prognostic value of microRNAs in heart failure: A meta-analysis.

BACKGROUND: Reported studies have shown that expression levels of microRNAs (miRNAs) are related to survival time of patients with heart failure (HF). A systematic review and meta-analysis were conducted to study circulating miRNAs expression and patient outcome. METHODS: Meta-analysis estimating expression levels of circulating miRNAs in HF patients from January 2010 until June 30, 2018, through conducting online searches in Pub Med, Cochrane Database of Systematic, EMBASE and Web of Science and reviewed by 2 independent researchers. Using pooled hazard ratio with a 95% confidence interval to assess the correlation between miRNAs expression levels and overall survival. RESULTS: Four relevant articles assessing 19 circulating miRNAs in 867 patients were included. In conclusion, the meta-analysis results suggest that HF patients with low expression of serum miR-1, miR-423-5p, miR-126, miR-21, miR-23, miR-30d, miR-18a-5p, miR-16-5p, miR-18b-5p, miR-27a-3p, miR-26b-5p, miR-30e-5p, miR-106a-5p, miR-233-3P, miR-301a-3p, miR-423-3P, and miR-128 have significantly worse overall survival (P  <  .05). Among them, miR-18a-5p, miR-18b-5p, miR-30d, miR-30e-5p, and miR-423-5p are strong biomarkers of prognosis in HF.

Pyloric gland adenoma with low-grade intraepithelial neoplasia: A case report and literature review.

RATIONALE: Pyloric gland adenoma (PGA) is often associated with pyloric gland metaplasia. It has high malignant potential but a low clinical diagnosis rate. Therefore, we reported a case of PGA and reviewed the literature to summarize the clinicopathological features of pyloric adenoma. PATIENT CONCERNS: A 62-year-old female underwent gastroscopy due to intermittent acid regurgitation and heartburn, which revealed a 4×6 mm flat, elevated lesion in the greater curvature of the upper gastric body, with depression in the central region and blood scab attachment. DIAGNOSIS AND INTERVENTION: Biopsy revealed gastric adenoma with low-grade intraepithelial neoplasia. The patient was treated with ESD, and pathology showed gastric pyloric gland adenoma with low-grade dysplasia. The cells were positive for MUC6 and MUC5AC immunohistochemically. OUTCOMES: The patient received proton pump inhibitors and gastric mucosal protective agents for one month after ESD. She occasionally presented acid regurgitation and heartburn, with no abdominal pain, abdominal distension, melena, or hematochezia. Follow-up gastroscopy will be reexamined 1 year later. LESSONS: PGA has nonspecific performance under endoscopy, and its diagnosis mainly depends on pathology. Clinicians need to increase their ability to recognize such lesions and treat them in time to improve the prognosis.

Partial versus total adrenalectomy for the treatment of unilateral aldosterone-producing adenoma: a systematic review and meta-analysis.

Adrenalectomy is the first line of treatment in unilateral aldosterone-producing adenoma. Whether adrenalectomy should be performed using a cortex-sparing technique (partial adrenalectomy) or total adrenalectomy remains debatable. Therefore, this meta-analysis aims to evaluate the safety and effectiveness of partial adrenalectomy (PA) to total adrenalectomy (TA) by comparing perioperative and functional outcomes. A systematic search was performed across Pubmed, Embase, Web of Science, Cochrane Library database for RCTs and non-RCTs comparing PA and TA on unilateral aldosterone-producing adenoma. The main outcomes analyzed were the perioperative and postoperative effectiveness. In addition, weighted mean difference (WMD) or odds ratio (OR) with 95% confidence intervals of continuous and dichotomous variables are presented. Two RCTs and 5 non-RCTs trials, including 834 patients were identified and included in the meta-analysis. PA was associated with statistically significant shorter hospital stay (WMD - 0.51 days, 95% CI - 0.87, - 0.14; p = 0.007), shorter operative time (WMD - 15.54 min, 95% CI - 25.12, - 5.97; p = 0.001) and lower overall complications (OR 0.52, 95% CI 0.32, 0.85; p = 0.009) compared to TA. There was no statistical significance in postoperative effectiveness, including postoperative blood pressure, potassium, hypokalemia, ARR and renin between TA and PA. PA seems to have advantages over TA. The surgical outcomes were comparable in TA and PA. The hospital stay, operative time and overall complications may be reduced. When technically feasible, PA might be considered as a better treatment for unilateral aldosterone-producing adenoma.

An Insight Into Intestinal Microbiota of Spontaneously Hypertensive Rats After Valsartan Administration.

It has been proven a close relationship between intestinal microbiota and hypertension. Valsartan is a widely used ARB antihypertensive drug; so far, the effect of valsartan on intestinal microbiota remains largely unexplored. Herein, we evaluated the composition, structure and metabolites of intestinal microbiota of spontaneously hypertensive rats (SHRs) after valsartan administration. In the present study, valsartan administration decreased intestinal microbiota diversity, altered gut microbiota composition, leading to 192 unique OTUs deficiency (vs WKY rats) and 10 unique OTUs deficiency (vs SHRs) and did not prove impaired intestinal mucosal barriers. Valsartan decreased the production of isobutyric acid and isovaleric acid in SCFAs. Our findings revealed valsartan administration induced far-reaching and robust changes to the intestinal microbiota of SHRs and provided a better understanding of the relationship between efficacy of valsartan and gastrointestinal tract reaction.

Study of the Mechanism Underlying the Antihypertensive Effects of Eucommia ulmoides and Tribulus terrestris Based on an Analysis of the Intestinal Microbiota and Metabonomics.

The combination of Eucommia ulmoides and Tribulus terrestris (ET) has been widely utilized in clinical practice for thousands of years, but the mechanism underlying its efficacy has not been elucidated to date. This study attempted to investigate the role played by the intestinal microbiota and fecal metabolism in the response of elderly spontaneous hypertensive rats (SHRs) to ET administration as a treatment for hypertension. Fourteen male spontaneously hypertensive rats (SHRs, 18 months old) were randomly divided into an ET group and an SHR group, and 7 Wistar-Kyoto (WKY) rats of the same age were employed as the control group. The ET group was intragastrically administered 1.0 g/kg/d ET for 42 days, and SHRs and WKY rats were administered an equal amount of normal saline intragastrically. The intestinal microbiota and fecal metabolism were analyzed by 16S rRNA sequencing and the GC-MS (gas chromatography-mass spectrometry)/MS assay. ET treatment decreased blood pressure steadily, improved the colonic tissue morphology, and changed the structure and composition of the imbalanced microbiota in SHRs. Specifically, ET treatment increased the abundance of Eubacterium, which might be one of the target microbes for ET, and had a negative correlation with the levels of α-tocopherol, chenodeoxycholic acid, and deoxycholic acid according to the Spearman correlation analysis. The change in the intestinal microbiota affected the fecal metabolic pattern of SHRs. Eight potential biomarkers were determined to be primarily enriched in ABC transporters, phenylalanine metabolism, central carbon metabolism in cancer, purine metabolism, and protein digestion and absorption. The correlation analysis demonstrated that the abundance of Eubacterium and the decreased levels of α-tocopherol, chenodeoxycholic acid, and deoxycholic acid in the ET group were highly correlated. Our results suggest that ET has a good antihypertensive effect, which may be driven by the intestinal microbiota and their beneficial metabolites. The results of this study may help to elucidate the antihypertensive mechanism of ET.

Efficacy of cystectasia in the treatment of ketamine-induced bladder contracture.

BACKGROUND: The treatment of ketamine-induced bladder contractures remains poorly studied. We therefore evaluated the efficacy of cystectasia with a sodium hyaluronate balanced solution in this kind of bladder contracture. METHODS: Eighteen patients presenting with ketamine-induced bladder contracture between July 2010 and February 2018 were selected and analysed. Ketamine was discontinued in all patients, who were then treated with weekly cystectasia (0.09% sodium hyaluronate balanced solution) 3 times. The volume of the first perfusion was twice the preoperatively measured bladder capacity, and the volume of the subsequent two perfusions was increased by 100 mL each time. The Pelvic Pain and Urgency/Frequency (PUF) symptom score, O'Leary-Sant Interstitial Cystitis (IC) Symptom Index (ICSI), IC Problem Index (ICPI), Quality of Life (QOL) score, and bladder capacity were recorded before surgery and 3 and 12 months after the 3rd expansion. RESULTS: No significant complications were observed during the 3 expansions. Fourteen patients completed the full follow-up schedule. Preoperatively and at the 3- and 12-month follow-up evaluations performed after the 3rd expansion, the PUF symptom scores were 20.4±3.6, 11.5±3.1, and 13.2±3.3, respectively; the mean ICSI was 13.6±2.8, 7.7±2.3, and 8.2±2.5, respectively; the mean ICPI was 10.6±2.6, 7.3±2.1, and 7.7±2.5, respectively; and the mean QOL scores were 6.0±0, 2.1±0.5, and 2.7±0.8, respectively; and the mean bladder catheter volume was 83±27, 234±56, and 228±52 mL, respectively. There were significant differences between all preoperative and postoperative values. CONCLUSIONS: Cystectasia with a sodium hyaluronate balanced solution is an effective treatment modality for ketamine-induced bladder contracture.

Gastric adenocarcinoma of the fundic gland type: A case report.

INTRODUCTION: Gastric adenocarcinoma of the fundic gland type (GA-FG) is a newly described entity that is characterized by well-differentiated neoplasm with unclear etiopathogenesis. PATIENT CONCERNS: A 60-year-old Chinese man was referred to our hospital for abdominal distension. DIAGNOSIS: Esophagogastroduodenoscopy (EGD) showed a depressed lesion found using in the greater curvature of the stomach. The pathological diagnosis of the biopsy specimens indicated that the tumor was GA-FG (chief cell predominant type, GA-FG-CCP). INTERVENTIONS: Endoscopic submucosal dissection (ESD) was performed. The histopathological examination of the ESD specimen revealed gastric hyperplasia of the fundic gland type around the adenocarcinoma cells. OUTCOMES: The surgical outcomes were good. The EGD showed a scar with no recurrence, and no symptoms were observed 1 year postoperatively during the follow-up. CONCLUSION: We present a rare case of a depressed lesion with a pathogenic expression suggesting gastric hyperplasia of the fundic gland type around the adenocarcinoma cells. Considering the origin of oxyntic mucosa, we consider that it may develop into GA-FG. To understand this issue better, similar cases should be monitored in the future.
