RESUMO
OBJECTIVES: This study aims to evaluate the impact of anterior fibromuscular stroma preserved enucleation (AFSPE) of the prostate on serum testosterone levels in patients with benign prostatic obstruction (BPO) and to explore age-related differences in postoperative testosterone elevation. METHODS: In a retrospective analysis, 304 patients from a pool of 560 who underwent AFSPE at Linkou Chang Gung Memorial Hospital between January 2018 and December 2021 were evaluated. Patients were stratified based on preoperative testosterone levels into low (<3.5 ng/mL) and normal (≥3.5 ng/mL) groups. Serum testosterone levels were measured preoperatively, at 1.5 and 3-6 months postoperatively. Age and other demographic data were analyzed as potential factors influencing testosterone changes. RESULTS: The low-testosterone group (n = 90) showed significant testosterone increases, from an average of 2.61 ng/mL preoperatively to 3.3 ng/mL at 1.5 months and 3.59 ng/mL at 3-6 months postoperatively (p < 0.0001). The normal-testosterone group (n = 214) maintained stable testosterone levels at 1.5 months but exhibited a significant rise to 6.06 ng/mL by 3-6 months (p = 0.0079). Older age was inversely associated with postoperative testosterone elevation in both groups. Improvements in nocturia were notable in both groups. CONCLUSIONS: AFSPE of the prostate significantly elevates serum testosterone levels in men with BPO, particularly benefiting those initially with low levels. Age is a crucial factor influencing postoperative testosterone changes, indicating that younger patients may benefit more from this intervention. AFSPE offers a promising approach for improving hormonal health in BPO patients, alongside alleviating urinary symptoms.
RESUMO
The association between short-term changes in serum magnesium level and risk of in-hospital mortality was investigated in patients with acute myocardial infarction (AMI). In this retrospective cohort study, data of 2,716 patients with AMI were extracted from the Medical Information Mart for Intensive Care (MIMIC-III and MIMIC-IV) database for 2001-2012. Univariate and multivariate Cox proportional hazards models were used to explore the association between serum magnesium level and short-term change and in-hospital mortality in patients with AMI. In addition, subgroups according to age, gender, Sequential Organ Failure Assessment (SOFA) score, and Simplified Acute Physiology Score (SAPS-II) were also analysed. In total, 504 (18.6%) patients died in hospital. After adjusting for covariates, all AMI patients with high magnesium levels at ICU admission (HR=1.03, 95% CI: 0.83-1.27) or 48 hours after ICU admission (all p<0.05), or those demonstrating a change in magnesium level within the first 48 hours of ICU stay (all p<0.05) were shown to have a high risk of in-hospital mortality. Moreover, this correlation was retained irrespective of age, gender, SOFA score, and SAPS-II (all p<0.05). Serum magnesium levels at different time points after ICU admission and change in serum magnesium level during the first 48 hours were associated with in-hospital mortality in patients with AMI, indicating that clinical attention should be paid to short-term changes in serum magnesium levels regarding treatment adjustment, which may further reduce the risk of mortality.

STUDY OBJECTIVE: Emergency department (ED) screening for child physical abuse has been widely implemented, with uncertain effects on child abuse identification. Our goal was to determine the effect of screening on referrals to child protective services (CPS) identifying abuse. METHODS: We performed a retrospective cohort study of children younger than 6 years old with an ED encounter at 1 of 2 large health care systems, one of which implemented routine child abuse screening. The main outcome was initial (<2 days) or subsequent (3 to 180 days) referral to CPS identifying child abuse using linked records. We compared outcomes for the 2-year period after screening was implemented to the preperiod and nonscreening EDs using generalized estimating equations to adjust for sex, age, race/ethnicity, payor and prior ED encounters and clustered by center. RESULTS: Of the 331,120 ED encounters, 41,589 (12.6%) occurred at screening EDs during the screening period. Screening was completed in 34,272 (82%) and was positive in 188 (0.45%). Overall, 7,623 encounters (2.3%) had a subsequent referral, of which 589 (0.2%) identified moderate or severe abuse. ED screening did not change initial (adjusted odds ratio [aOR]=1.01, 95% confidence interval [CI] 0.89 to 1.15) or subsequent referral to CPS when compared to the prescreening period (aOR=1.05, 95% CI 0.9 to 1.18) or to the nonscreening EDs (aOR=1.06, 95% CI 0.92 to 1.21). CONCLUSION: Routine screening did not affect initial or subsequent referrals to CPS.
RESUMO
BACKGROUND: The functions of activating transcription factor 3 (ATF3) within the human bladder remain unexplored. This study delves into the expressions, functions, and regulatory mechanisms of ATF3 in human bladder cancer. MATERIAL AND METHODS: Gene expressions were determined by immunoblot, RT-qPCR, and reporter assays. Assays of Ki67, colony formation, Matrigel invasion, and the xenograft animal study were used to assess the cell proliferation, invasion, and tumorigenesis in vitro and in vivo. Silico analysis from TCGA database examined the correlations between GDF15 and ATF3 expressions, clinicopathologic features, and progression-free survival rates. RESULTS: Silico analysis confirmed that ATF3 is an antitumor gene, and the expression positively correlates with GDF15 in bladder cancer tissues. Multivariate analysis revealed that low ATF3/GDF15 but not a single low expression of ATF3 is an independent prognostic factor for progression-free survival of bladder cancer patients. Ectopic overexpression of ATF3 downregulated cell proliferation and invasion in bladder cancer cells in vitro, while ATF3-knockdown reversed these results. Knockdown of ATF3 upregulated EMT markers to enhance cell invasion in vitro and downregulated GDF15, NDRG1, and KAI-1 to elevate tumor growth in vivo. The activation of metformin on ATF3 and GDF15 in bladder cancer cells was blocked by SB431542, a TGFß receptor inhibitor. ATF3 positively regulated GDF15 expression in bladder cancer cells through a feedback loop. CONCLUSIONS: Our results identify that ATF3 is a metformin-upregulated antitumor gene. Results of Silico analysis align with cell-based studies suggesting that low ATF3/GDF15 could be a negative prognostic marker for bladder cancer.
RESUMO
PURPOSE: This study is centered on the critical role of anterior fibromuscular stroma (AFS) preservation in prostate enucleation, an emerging strategy aimed at minimizing postoperative urinary incontinence-a common concern in benign prostatic hyperplasia (BPH) surgeries. By focusing on postoperative voiding volumes (VV), our research investigates the efficacy of AFS preservation. This approach, distinct in its methodology, is hypothesized to improve urinary function post-surgery, thereby offering a potentially significant advancement in BPH surgical treatments. MATERIALS AND METHODS: A retrospective analysis was conducted, comparing patients who underwent prostate enucleation in 2017 without intentional AFS preservation to those in 2019 with this technique. We examined variables including age, BMI, diabetes, hypertension, and preoperative VV to assess their effect on post-catheter removal VV. The study's methodology includes a thorough review of the primary statistical analysis methods employed. RESULTS: Our analysis indicates that while the 2017 and 2019 cohorts were similar in most preoperative parameters, the 2019 group that underwent AFS-preserved surgery showed a significant improvement in postoperative VVs. This was less pronounced in the patient group aged over 70, underscoring the importance of this demographic in our study. CONCLUSIONS: The study concludes that intentional preservation of AFS during prostate enucleation positively impacts early postoperative VVs, with limited improvement in older patients. These findings highlight the potential of AFS preservation not only in enhancing urinary outcomes post-surgery but also in shaping future BPH surgical procedures and research directions.

This study examines the predictive value of elevated N-terminal-pro brain natriuretic peptide (NT-pro BNP) levels for mortality among patients with end-stage renal disease (ESRD). Data from 768 ESRD patients, excluding those with cancer or lost follow-up, were analyzed using Kaplan-Meier curves and Cox proportional hazards models over three years. Results indicated that patients with very high NT-pro BNP levels had shorter average survival times and a significantly higher risk of mortality (hazard ratio 1.43). Advanced age, ICU admission, and comorbidities like cerebrovascular diseases and chronic obstructive pulmonary disease also contributed to increased mortality risks. Thus, elevated NT-pro BNP is an independent risk factor for mortality in ESRD patients.
RESUMO
PURPOSE: Postoperative urinary retention (PUR) is a common complication after prostate enucleation, which leads to an increased length of hospital stay and decreased postoperative satisfaction. This study determined the predictive factors of postoperative urine retention within 1 month after prostate enucleation and investigated whether PUR influences surgical outcomes at the 2-week, 3-month, and 6-month follow-up time points. METHODS: Data were collected from the electronic medical records of 191 patients with benign prostatic obstruction (BPO) during October 2018 to September 2021. Of them, 180 patients who underwent thulium laser or plasma kinetic enucleation of the prostate (ThuLEP, PKEP) were separated into the PUR group (n = 24) and the non-PUR (NPUR) group (n = 156). Uroflowmetry and the International Prostate Symptom Score (IPSS) questionnaire were followed up at 2 weeks, 3 months, and 6 months postoperatively. RESULTS: The PUR group had a significantly higher percentage of patients with type 2 diabetes mellitus (DM) than the NPUR group. Postoperatively, compared with the NPUR group, the PUR group had significantly less improvement in changes in the IPSS Quality of Life scores at 2 weeks, the total IPSS(International Prostate Symptom Score) at all follow-up times, the IPSS-S(IPSS storage subscores) at 2 weeks and 3 months, and the IPSS-V(IPSS voiding subscores) at all follow-up times. Predictive factors for PUR include lower preoperative maximum urinary flow (Qmax), lower preoperative total IPSS, and higher operation time. CONCLUSION: Lower preoperative Qmax, lower IPSS scores, and longer operation time were risk factors for PUR. Furthermore, PUR could be a prognostic factor for prostatic enucleation surgical outcomes.

OBJECTIVES: This study aims to investigate the surgical outcomes of endoscopic enucleation of the prostate in older males with or without preoperative urinary retention (UR). MATERIAL AND METHODS: We conducted a study on selected patients with symptomatic benign prostatic hyperplasia (BPH) who underwent either thulium:YAG laser (vela XL) prostate enucleation (ThuLEP) or bipolar plasma enucleation of the prostate (B-TUEP) at the geriatric urology department of our institution. The studied patients were categorized into two groups, namely the UR group and the non-UR group, on the basis of whether they experienced UR in the 1 month preceding their surgery. Their clinical outcomes following prostate endoscopic surgery were evaluated and analyzed. RESULTS: Our results revealed comparable outcomes for operation time, length of hospital stay, percentage of tissue removed, re-catheterization rate, and urinary tract infection rate within the 1 month between the B-TUEP and ThuLEP surgery groups, regardless of UR history. However, the non-UR B-TUEP group experienced more blood loss relative to the non-UR ThuLEP group (P = .004). Notably, patients with UR exhibited significantly greater changes in IPSS total, IPSS voiding, and prostate-specific antigen values relative to those without UR. CONCLUSIONS: Both ThuLEP and B-TUEP were effective in treating BPH-related bladder outlet obstruction. Our study identified more pronounced changes in IPSS total, IPSS voiding, and prostate-specific antigens within the UR group. Moreover, the rate of postoperative UR in this group was not higher than that observed in the non-UR group. Our study also revealed that the presumed benefits of laser surgery in reducing blood loss were less pronounced for patients with UR.

Clear cell renal cell carcinoma (ccRCC) stands as a challenging subtype of kidney cancer, frequently complicating patient prognosis due to factors like postsurgical recurrences or late-stage diagnoses. In this study, we employed bioinformatics to investigate lactylation modifications in ccRCC, focusing on the TCGA-KIRC cohort. Out of 328 lactylation-associated genes, 31 emerged as differentially expressed, with 16 showing a marked correlation with overall survival. These genes exhibited strong protein-protein interactions and significant expression correlations. Intriguingly, a notable loss of gene copy numbers suggests potential implications in tumor progression. Utilizing unsupervised clustering, KIRC samples were grouped into two distinct subcategories, each showcasing different survival outcomes. While pathway enrichment highlighted an aggressive, inflammation-driven profile for subgroup 2, subgroup 1 was characterized by metabolic prominence. Furthermore, subgroup 2 presented an intensified inflammatory response, hinting at potential immune exhaustion. Capitalizing on machine learning, we developed a risk model using the TCGA-KIRC dataset, efficiently categorizing ccRCC patients into high- and low-risk clusters. Notably, those in the low-risk group indicated a more favorable survival trajectory. Clinical evaluations further corroborated these findings, linking better outcomes with reduced risk scores. Additionally, observed mutation patterns allude to a potential association between elevated risk scores and cytokine storms. TIDE analysis illuminated possible immunotherapeutic benefits for the low-risk group, underscored by an evident rise in microsatellite instability. Finally, our drug sensitivity evaluations revealed distinct therapeutic responses between the groups. In summary, this research underscores the pivotal role of lactylation modifications in ccRCC and introduces a promising prognostic model. These revelations pave the way for enhanced prognostic precision, presenting a promising path toward personalized treatment strategies and enriching our comprehension of the multifaceted molecular landscape of the disease.

RAD51 recombinase is one of the DNA damage repair proteins associated with breast cancer risk. Apart from its function to maintain genomic integrity within the cell nucleus, RAD51 localized to the cytoplasm has also been implicated in breast malignancy. However, limited information exists on the roles of cytoplasmic vs. nuclear RAD51 in breast cancer progression and patient prognosis. In the present study, the association of cytoplasmic and nuclear RAD51 with clinical outcomes of patients with breast cancer was analyzed, revealing that elevated cytoplasmic RAD51 expression was associated with breast cancer progression, including increased cancer stage, grade, tumor size, lymph node metastasis and chemoresistance, along with reduced patient survival. By contrast, elevated nuclear RAD51 expression largely had the inverse effect. Results from in vitro investigations supported the cancerpromoting effect of RAD51, showing that overexpression of RAD51 promoted breast cancer cell growth, chemoresistance and metastatic ability, while knockdown of RAD51 repressed these malignant behaviors. The current data suggest that differential expression of subcellular RAD51 had a distinct impact on breast cancer progression and patient survival. Specifically, cytoplasmic RAD51 in contrast to nuclear RAD51 was potentially an adverse marker in breast cancer.

Background and Objectives: Urinary tract stones have long been a common ailment afflicting the population, with a high incidence and a wide distribution across different age groups. Effectively preventing the occurrence of urinary tract stones is of paramount importance. The primary aim of this study is to investigate the correlations between individual characteristics, water consumption habits, dietary habits, exercise habits, and the occurrence of urinary tract stones in a Taiwanese population. Materials and Methods: This study is cross-sectional research conducted over one month in 2022. One hundred eligible urinary stone cases were recruited through physician screening at outpatient clinics, and an additional one hundred samples from surgical outpatients without urinary tract stones were included as the control group. A questionnaire survey was employed to gather information on demographic variables, dietary habits, water consumption, and exercise habits of the cases. Descriptive statistics, chi-square tests, and logistic regression were used to explore the impact of relevant factors on urinary stone formation. Results: The analysis results revealed that among the demographic variables, males exhibited a higher risk of contracting urinary tract stones than females, and the majority of cases fell within the 40- to 49-year-old age group. Unhealthy lifestyle habits such as smoking and betel nut chewing also demonstrated a higher susceptibility to urinary tract stones. A logistic regression analysis showed that individuals who engaged in physical activity more than three times per week and those with inadequate water intakes had a higher risk of developing urinary tract stones. Conclusions: There is a close relationship between lifestyle and urinary tract stones. It is recommended that individuals continue to hydrate adequately during exercise.

Background and Objectives: This study evaluated and compared the surgical outcomes of retrograde intrarenal surgery (RIRS) lithotripsy versus robot-assisted laparoscopic pyelolithotomy (RAPL) in community patients with renal pelvic stones larger than 2 cm. Materials and Methods: A total of 77 patients who underwent RIRS (RIRS group, n = 50) or RAPL (RAPL group, n = 27) at our institution between December 2016 and July 2022 were recruited. A single surgeon performed all surgical operations. Preoperative, operative, and postoperative data were recorded. The study evaluated various clinical outcomes, namely, urinary tract infections, analgesic use, emergency room readmissions, stone clearance rates, surgical complications, and medical expenditures associated with the treatment courses, and compared them between the groups. Results: The RAPL group had a larger mean stone diameter and higher degree of hydronephrosis than the RIRS group did. The RIRS group had superior outcomes regarding operative time, length of postoperative hospital stay, surgical wound pain, and medical expenditures. Regarding postoperative outcomes, comparable rates of postoperative urinary tract infection, prolonged analgesic use, and emergency room readmissions were observed between the groups. However, the RAPL group had a higher stone clearance rate than the RIRS group did (81.5% vs. 52.0%, p = 0.014). Conclusions: For the surgical treatment of renal pelvis stones larger than 2 cm, RAPL has a superior stone clearance rate than RIRS; however, RIRS achieves superior outcomes in terms of medical expenditures, length of hospital stay, and surgical wound pain. Both procedures were equally safe.

Fumarase hydratase (FH) is an enzyme that catalyzes the reversible hydration and dehydration of fumarate to malate in the tricarboxylic acid cycle. The present study addressed the role of FH in endometrial cancer and clinically observed that the expression of FH was significantly lower in endometrial cancer tissues compared with normal endometrial tissues and, furthermore, that the decreased FH expression in endometrial cancer tissues was significantly associated with increased tumor size and lymph node metastasis. Further analysis in in vitro study showed that cell proliferation, migration and invasion abilities were increased when the expression of FH in the endometrial cancer cells was knocked down, but, by contrast, overexpression of FH in endometrial cancer cells decreased cell proliferative, migratory and invasive abilities. Mechanistic studies showed that the expression of vimentin and twist, being two well-studied mesenchymal markers in endometrial cancer cells, were upregulated in fumarate hydratase-knockdowned cells. In addition, phosphokinase array analysis demonstrated that the expression of phospho-EGFR (Y1086), which promotes carcinogenesis in cancers, was increased in endometrial cancer cells when FH was knocked down. In conclusion, the present study suggested that FH is a tumor suppressor and inhibits endometrial cancer cell proliferation and metastasis by inactivation of EGFR. Further studies are required to clarify its role as a prognostic biomarker and therapeutic target for endometrial cancer.

Background: Lower extremity venous disease (LEVD) is a complex disorder, and determining the etiology of LEVD is paramount for treatment selection. Two-dimensional phase-contrast magnetic resonance imaging (2D PC-MRI) can provide an objective measure of hemodynamic status and may help differentiate between different etiologies of LEVD. A total of 271 participants, including 256 symptomatic patients with venous lower extremity disease and 15 healthy volunteers, were collected in this cohort study. Methods: It is a single-center prospective observational study using 2D PC-MRI analysis to assess the hemodynamic characteristics of patients with LEVD among participants recruited between April 2017 and October 2021 at a tertiary hospital. The approval institutional review board number for this study were 201802137B0, 201901058B0, 202100938B0, and 202102344B0. Participants were classified as venous reflux (VR) and venous obstruction (VO) by standard ultrasonography. 2D PC-MRI by 1.5 T scanner revealed stroke volume (SV), forward flow volume (FFV), absolute stroke volume (ASV), mean flux (MF), velocity time integral (VTI), and mean velocity (MV) for each selected venous segments. Results: 2D PC-MRI assessed 167 diseased legs from the 116 VR patients [mean age ± standard deviation (SD): 57.9±12.8 years; 39 males] and 113 diseased legs from the 95 VO patients (mean age ± SD: 66.4±12.8 years; 42 males). 2D PC-MRI analysis demonstrated discrimination ability to differentiate from VR to VO [SV, FFV, ASV, MF, VTI, and MV in the various venous segments, respectively, P≤0.001; area under the curve (AUC) =62-68.8%, P≤0.001 by Mann-Whitney U test]. The ratio data (morbid limb to normal limb) in the same individual with single-leg disease revealed differences between VR and VO (SV, FFV, ASV, and MF in the various venous segments, respectively; P<0.05; AUC =60.2-68.7%, P≤0.05 by Mann-Whitney U test). The most favorable differentiating variables of ratios were FFV in the great saphenous veins [AUC =68.7%, 95% confidence interval (CI): 59.8-77.6%] and ASV in the external iliac veins (AUC =67.4%, 95% CI: 58.7-76.2%). Conclusions: Quantitative 2D PC-MRI analysis is capable of differentiating VR from VO. It also provides an important diagnostic capability for preoperative evaluation.
RESUMO
BACKGROUND: To explore the mediator role of depression in the association of osteoarthritis (OA) and cardiovascular disease (CVD) mortality based on the National Health and Nutrition Examination Survey (NHANES) database. METHODS: Totally 19,605 adults from NHANES 2009-2018 were included in this cohort study ultimately. The outcome was considered as the CVD related mortality in this study. The follow-up duration was 81.09 ± 1.05 months. Weighted univariate and multivariate linear regressions were used to explore the association between OA and depression. Weighted univariate and multivariate COX regressions were performed to assess the relationship of OA and CVD related mortality. Also, we analyzed the mediating role of depression on the association between OA and CVD mortality through the Sobel Test. RESULTS: The CVD related mortality in this study was 2.57 %. After adjusting age, gender, physical activity, history of CVD, history of hypertension and eGFR, OA was positively correlated with depression [ß = 0.78, 95 % confidence interval (CI) = 0.54-1.02], and OA was associated the death risk of CVD [hazard ratio (HR): 1.35, 95%CI, 1.09-1.68]. Additionally, depression slightly mediated the association between OA and CVD related mortality in this study, with this mediating variable accounting for 5.61 % of the association. CONCLUSION: OA was associated with depression and CVD related mortality, respectively. Additionally, the increased risk of CVD related mortality in OA patients may be slightly mediated by depression. These results serve as a reminder that giving careful attention to and effectively managing mental health may be beneficial to prevent CVD related mortality, especially for those with OA.

Cerebral Small Vessel Disease (CSVD) frequently affects the elderly, with inflammation playing a crucial role in related health complications, including dementia, stroke, and SVD. Studies, including animal experiments, indicate a strong link between inflammation and SVD progression. The Neutrophil-Lymphocyte Ratio (NLR) serves as a possible biomarker for ongoing inflammatory risks. A total of 720 adults aged 50 years or older from the community-based I-Lan Longitudinal Aging Study were included in this study. General linear regression and ordinally logistic regression analyses were performed to evaluate the association between NLR and CSVD. We further examined the presence of lacune, microbleed, and white matter hyperintensity (WMH) on brain MRI, which were used to construct a combined CSVD score. The NLR was positively associated with WMH (adjusted r = 0.109, p = 0.003), microbleed (adjusted r = 0.102, p = 0.006), and lacune (adjusted r = 0.100, p = 0.008). After adjustments for smoking, drinking, and physical activity in the ordinal logistic regression analysis, age, gender, brachial Systolic Blood Pressure (SBP), fasting glucose, LDL-cholesterol, and Hs-CRP were compared among subjects with low tertile (T1), medium tertile (T2) and high tertile (T3) NLR. The results showed that T2 vs. T1 had an odds ratio of 1.23 (0.86-1.77); and T3 vs. T1 had an odds ratio of 1.87 (1.29-2.71) of CSVD scores in four groups (zero (reference group), one, two, and three or more). NLR could be used to assess the state of inflammation in cerebral vessels. A significant and positive correlation between NLR and CSVD was verified in this study. However, the practical clinical application of NLR in CSVD patients and prognosis prediction should be validated through more scientific attempts.
RESUMO
The androgen-dependent or -independent pathways are regarded as primary therapeutic targets for the neoplasm of the prostate. Mucosa-associated lymphoid tissue 1 (MALT1) acting as a paracaspase in the regulation of nuclear factor κB (NF-κB) signal transduction plays a central role in inflammation and oncogenesis in cancers. This study confirmed the potential linkages between androgen and NF-κB activation by inducing MALT1 in the androgen receptor-full length (ARFL)-positive LNCaP and 22Rv1 prostate cancer cells. Although androgen did not stimulate MALT1 expression in AR-null or ectopic ARFL-overexpressed PC-3 cells, the ectopic overexpression of the AR splicing variant 7 (ARv7) upregulated MALT1 to activate NF-κB activities in 22Rv1 and PC-3 cells. Since the nuclear translocation of p50 and p65 was facilitated by ARv7 to motivate NF-κB activity, the expressions of MALT1, prostate-specific antigen (PSA), and N-myc downstream regulated 1 (NDRG1) were therefore induced in ectopic ARv7-overexpressed prostate cancer cells. Ectopic ARv7 overexpression not only enhanced 22Rv1 or PC-3 cell growth and invasion in vitro but also the tumor growth of PC-3 cells in vivo. These results indicate that an androgen receptor induces MALT1 expression androgen-dependently and -independently in ARFL- or ARv7-overexpressed prostate cancer cells, suggesting a novel ARv7/MALT1/NF-κB-signaling pathway may exist in the cells of prostate cancer.
