Emergency rapid reversal of coumarin associated over-anticoagulation in a case of ruptured ovarian hemorrhagic cyst for surgery: A case report

Over-anticoagulation with coumarins is not uncommon in poorly followed-up patients whose international normalized ratio (INR) is not regularly monitored. Various treatment options available for emergency reversal of over-anticoagulation are either used alone or in tandem. A 36-year-old female with a history of aortic valve replacement came with complaints of severe generalized abdominal pain and hematuria. Hemoglobin was 5 mg/dL, and the INR value was >27.5. Ultrasonography had left a ruptured hemorrhagic ovarian cyst with hemoperitoneum. With a hematology consult, various products were used to reverse the over-anticoagulation. Two liters of hemoperitoneum drainage and left salpingo-oophorectomy were done laparoscopically. Post-surgical recovery was unremarkable, INR was stabilized, and 2 days later, the patient was shifted to the ward. As an anesthetist and critical care physician, it is important to stabilize, optimize, diagnose, and treat these conditions with the aid of various other specialties in a limited amount of time to prevent adverse events that can be fatal.

Risk of Incident Genitourinary Cancer Following Hematuria in Patients with Atrial Fibrillation Receiving Oral Anticoagulants

BackgroundHematuria is common in patients with atrial fibrillation (AF) on oral anticoagulants (OAC). However, risks of incident genitourinary (GU) malignancy and detailed etiologies of hematuria have not been well studied. ObjectiveWe aimed to investigate the risk of hematuria and underlying GU malignancy in AF patients receiving OACs. MethodsA total of 192,728 AF patients receiving OACs were identified from Taiwan National Health Insurance Research Database. The risk of hematuria was compared between patients receiving warfarin (n = 75,541) and non-vitamin K antagonist OACs ([NOACs], n = 117,187). Among them, 18,509 patients experiencing hematuria without prior history of GU malignancy were defined as the study population. One-year risks of GU cancers were studied and compared between warfarin and NOAC users. ResultsCompared to warfarin, NOACs were associated with a higher risk of mild (2.29%/year vs 1.71%/year, adjusted hazard ratio [aHR] 1.107, p<0.0001) or moderate hematuria (0.84%/year vs 0.62%/year, aHR 1.075, p=0.0189), but a lower risk of severe hematuria (0.15%/year vs 0.17%/year, aHR 0.630, p<0.0001). Within one year after hematuria, 738 (3.99%) patients were diagnosed to have incident GU cancers and the risk was higher among warfarin compared to NOAC users (4.10% vs 3.89%, odds ratio [OR] 1.1169, p=0.041). Age ≥75 years (OR 1.486, p<0.0001), male gender (OR 2.342, p<0.0001) and abnormal renal function (OR 1.319, p=0.0015) were important clinical factors associated with the diagnosis of GU cancer. ConclusionGU malignancy occurs in around 4% of anticoagulated AF patients experiencing hematuria. Comprehensive evaluations of underlying etiologies of hematuria are necessary.

BK virus associated hemorrhagic cystitis in pediatric patients undergoing hematopoietic stem cell transplantation

Abstract Background BK virus (BKV) is one of the most common causes of hemorrhagic cystitis (HC) in children undergoing hematopoietic stem cell transplantation (HSCT). Methods Descriptive and retrospective study that included patients from 0-18 years old undergoing HSCT with a diagnosis of HC, admitted from 1/1/2018 to 11/30/2023 in a tertiary care pediatric hospital. Patients with HC were tested for BKV by quantitative polymerase chain reaction (PCR) in urine samples, if positive, plasma viral load was also requested. BKV-HC grading was defined by the European Conference on Infections in Leukemia (ECIL) consensus document. Asymptomatic patients did not undergo standardized screening for BKV. Results During this period 86 HSCT were performed for either malignant (75,6%) or non-malignant disorders (24,4%). Overall, 16 (18,6%) were autologous and 70 (81.4%) were allogeneic: 40 human leukocyte antigen (HLA) matched unrelated donor, 26 HLA-matched related donor and 4 haploidentical. Six patients (7%) suffered HC, all associated with BKV as the cause. These six patients underwent allogeneic HSCT, and 4 of them had HLA-matched unrelated donors. All patients were over 5 years old. Male sex predominated (n:5). All of the patients had hematologic malignancies as the underlying diagnosis (5 with acute lymphoblastic leukemia - ALL). The stem cell source was bone marrow in 3 patients and peripheral blood in the other 3. All patients received myeloablative conditioning regimen and 4 underwent total body irradiation. Only one patient received post-transplant cyclophosphamide. Symptoms (dysuria, abdominal pain, macroscopic hematuria, clots) began more than 14 days after HSCT in 100% of the cases. Hematuria was categorized as grade III in 5 patients and grade IV (severe) only in one. All patients tested positive for BKV PCR in urine samples. High-level BK viruria (&amp;gt;107 copies/mL) was found in 66,6%. BK viremia was detected in 4 patients. All of the patients had another concomitant viral infection, with cytomegalovirus reactivation being the most frequent (n:4). Two patients also had detectable adenovirus (ADV) PCR in urine samples. Acute graft versus host disease (GVHD) was diagnosed in 5 patients, all with skin involvement. All patients were hospitalized and prolonged the length of stay. Regarding treatment, they all received hyperhydration and Cidofovir (more than 3 doses). Dose of immunosuppressive treatment was reduced in 5 cases. Acute kidney failure (AKF) was found in 3 patients. One patient developed chronic kidney failure. The patient with no GVHD was the one who improved the fastest. The patient with severe hematuria required bladder irrigation, had dialysis indication and presented a related death. Conclusion The development of BKV-HC in HSCT patients results in suffering and pain, prolonged hospitalizations and significant morbidity (AKF). Literature shows that male sex, older age and acute GVHD are important risk factors, and this is what we also found in our case series. BKV-HC is considered a difficult and severe condition to manage, remaining troublesome so we should overcome this deficiency with new approaches, particularly emphasizing in preemptive or prophylaxis measures for the benefit of our patients.

Gross hematuria and congestive heart failure – two sides of the same coin

Poststreptococcal glomerulonephritis (PSGN) is an immune-mediated disease following infection with nephritogenic strains of group A β-hemolytic Streptococcus (GAS), affecting children aged of 2 to 10. We report 2 different presentations of PSGN from “Grigore Alexandrescu” Hospital. Case 1: A 5 years old girl was admitted for gross hematuria. Investigations revealed: anemia, inflammatory syndrome, mild nitrogen retention syndrome, elevated ASO and low levels of serum C3, nephritic-range proteinuria and severe hematuria. she received antibiotic treatment with initial improvement. A relapse occurred in one week, a second course of antibiotic and corticosteroids was necessary. Case 2: A 15-year-old girl was admitted for acute cardiac failure, hypertension and oliguria. Investigations revealed anemia, nitrogen retention, dyslipidemia, inflammatory syndrome, high ASO titers, low serum C3, microscopic hematuria, nephrotic-range proteinuria. She had fluid build-up in both lungs and pericardium. The diagnosis was PSGN and congestive heart failure (volume overload). She received antibiotics, diuretics and ACE inhibitors. PSGN is re-emerging in pediatric practice due to the resurgence of streptococcal infections within children's communities. The clinical presentation might be highly variable, ranging from hematuria to heart failure. Clinicians should be aware and actively consider this diagnosis.

A patient with Behcet’s disease and IgA nephropathy in China

BackgroundBehcet’s disease (BD) is an inflammatory disorder of unknown cause that is characterized by recurrent oral aphthous ulcers, genital ulcers, uveitis, and skin lesions. Local vasculitis can cause damage to the visceral system, but it is rare in kidney patients, especially those with IgA nephropathy (IgAN). In China, a small number of related cases have been reported. Here we present a case of co-occurrence of BD and IgAN.Case presentation: An 18-year-old female who presented with a history of recurrent oral ulcers was found ten years ago. Four years later, the patient presented with reddish nodules on the skin of both lower limbs and then presented with vulvar ulcers. This patient was clinically diagnosed with Behcet’s disease after left calf skin biopsy and presented severe proteinuria and hematuria during this period. IgAN was diagnosed after percutaneous renal biopsy. The patient was treated with hormonal, anti-inflammatory, immunomodulatory, kidney protective, and protein-lowering urine agents. After 3 years of follow-up, the patient reappears oral ulcers, reddish nodules on the skin of both lower limbs and renal dysfunction.ConclusionsBD is less common in China and is clinically prone to missed diagnosis and misdiagnosis. BD with IgAN is rarer. We should regularly pay attention to the routine urine and renal function of BD patients for early detection and treatment and to prevent further progression of the disease.

Comparative efficacy of different surgical techniques for pediatric urolithiasis-a systematic review and meta-analysis.

Prior research has assessed a range of surgical treatments for pediatric urolithiasis, emphasizing the necessity of tailor-made therapeutic approaches. These studies also show the adaptability of percutaneous nephrolithotomy (PCNL), retrograde intrarenal surgery (RIRS), and shock wave lithotripsy (SWL) in managing diverse stone dimensions. The goal of this research was to examine the effectiveness of these varying surgical methods in treating pediatric urolithiasis. Seven digital databases were explored to gather pertinent studies, following the guidelines established by the PRISMA protocol. The retrieved studies were subsequently scrutinized to draw comparisons between the stone-free rate (SFR) and the rate of complications associated with PCNL, RIRS, and SWL. The SFR evaluation revealed no notable disparity between PCNL and RIRS [odds ratio (OR) 1.43, 95% confidence interval (CI): 0.67-3.05, P=0.36]. However, it was observed that both PCNL and RIRS outperformed SWL in terms of effectiveness (OR 2.51, 95% CI: 1.19-5.29, P=0.02 and OR 2.42, 95% CI: 1.41-4.14, P=0.001 respectively). Regarding the complication rates, no significant differences were observed among the three surgical methods (OR 0.67, 95% CI: 0.49-1.59, P=0.05), albeit with various forms of complications being reported. Certain studies associated PCNL with an elevated rate of complications, specifically urinary tract infections (UTIs) and severe hematuria. Though PCNL and RIRS demonstrated higher effectiveness than SWL in achieving SFR, there was no significant disparity in the rates of complications across all three procedures. The study underscores the significance of personalized treatment plans, taking into account aspects such as the dimension and location of the stone, along with patient-specific characteristics.

Urgent Transurethral Resection of a Massive Bladder Clot in a Hemodynamically Unstable Patient

This case report describes a 58-year-old male with a history of chronic smoking who presented with severe hematuria and hemodynamic instability. Initial assessment revealed a massive bladder clot and critically low hemoglobin. Despite initial interventions, the patient suffered cardiac arrest requiring prolonged resuscitation. Emergency cystoscopy was performed, removing a 320-gram clot and resecting a 2 cm bladder tumor. Despite successful surgical intervention and post-operative intensive care, the patient succumbed to multi-organ failure six days later. This case highlights the potential severity of hematuria and the importance of prompt diagnosis and treatment of underlying causes. It also demonstrates the challenges in managing complex cases involving massive hemorrhage, hemodynamic instability, and the sequelae of prolonged cardiac arrest.

Renal artery embolization in a case of renal cell carcinoma with intractable hematuria with acute myocardial infarction

Introduction: Renal artery embolization is a valuable treatment option for various renal tumors, both malignant and benign. The indications for this procedure include preoperative arterial embolization of large and vascular renal cell carcinoma to reduce intraoperative hemorrhagic complications, management of malignant renal tumors in patients who are not suitable candidates for surgery, treatment of symptomatic hematuria and palliative care for metastatic renal cancer. Case Report: In this case report, we present the case of a 56-year-old female with a known history of hypertension and cerebrovascular accident, who presented with complaints of hematuria and urinary retention. A diagnosis of left renal mass suggestive of renal cell carcinoma was made. The patient was planned for left radical nephrectomy and advised to discontinue aspirin for a week. However, on the morning of surgery, she experienced acute myocardial infarction and had to be hospitalized in intensive cardiac care. Aspirin was restarted, leading to recurrent severe hematuria. The patient underwent renal artery embolization, which successfully controlled the hematuria. Following cardiac stabilization, radical nephrectomy was performed three months later. The surgery and post-operative period were uneventful. Conclusion: This case study demonstrates the use of renal artery embolization as an effective modality for controlling hematuria, and temporizing management in a case of renal cell carcinoma where surgery was not immediately feasible due to a medical emergency.

Clinicopathologic Characteristics of Crystalglobulin-Induced Nephropathy: A Case Series

Crystalglobulinemia is a rare syndrome characterized by intravascular crystallization of monoclonal immunoglobulins (MIgs). Data on kidney involvement are limited to case reports. This series characterizes the clinicopathologic spectrum of crystalglobulin-induced nephropathy (CIN). Case series. Nineteen CIN cases were identified from the nephropathology archives of Mayo Clinic and Columbia University. CIN was defined by intravascular (extracellular) MIg crystals visible by light (LM) and electron microscopy (EM). Among the cases, 68% were male and 65% were Caucasian (median age 56 years). Most patients presented with severe AKI (median creatinine 3.5 mg/dL), hematuria, and mild proteinuria (median 1.1 g). Common extrarenal manifestations were constitutional (67%), cutaneous (56%), and rheumatologic (50%). Fifty percent of cases had hypocomplementemia. The hematologic disorders were monoclonal gammopathy of renal significance (MGRS) (72%), lymphoma (17%), or myeloma (11%), with 65% of these disorders discovered concomitantly with CIN. All patients had MIg identified on SPEP/SIF (IgGκ in 65%). The sFLC ratio was outside the renal range in 40%, and bone marrow biopsy detected the responsible clone in 67%. On LM, crystals involved glomeruli (100%) and vessels (47%), often with an inflammatory reaction (89%) and fibrin (58%). All cases exhibited crystal substructures (mostly paracrystalline) by EM. Immunofluorescence (IF) on paraffin embedded tissue was more sensitive than frozen tissue (92% versus 47%) for demonstrating the crystal composition (IgGκ in 63%). Follow up (median 20 months) was available in 16 patients. Eighty-one percent received steroids, 44% plasmapheresis, 38% hemodialysis, and 69% chemotherapy. Ninety-percent of patients who received clone-directed therapy achieved kidney recovery vs. 20% of those who did not (p=0.017). Retrospective design, small sample size. CIN is a rare cause of nephropathy associated with lymphoplasmacytic disorders (mostly MGRS) and typically presents with severe AKI and extrarenal manifestations. Diagnosis often requires IF performed on paraffin embedded kidney tissue. Prompt initiation of clone-directed therapy, coupled with corticosteroids and plasmapheresis, may lead to recovery of kidney function.

AIE-based fluorescent sensing of ciprofloxacin using non-fluorescent 2D silver dimolybdate nanosheets: The synergistic sensor method (SGSM) to switch on non-fluorescent 2D nanosheets into an effective fluorescent biosensor

The development of an efficient method for detecting ciprofloxacin (CIP) is critical due to the potential for significant harm to humans, including the danger of severe liver damage and hematuria associated with increased levels of this drug. In this study, we offer a highly sensitive and highly selective method for fluorescence sensing of the antibiotic ciprofloxacin employing the properties of Aggregation-Induced Emission (AIE) with silver dimolybdate nanosheets (Ag2Mo2O7 NSs). Outstanding structural characteristics of the Ag2Mo2O7 NSs achieved using the hydrothermal method. By carefully controlling the aggregation of the Synergistic Sensor Method (SGSM), we are able to produce a very bright fluorescence response with the ciprofloxacin concentration range from 0 to 250 nM with a low detection limit of 1.1 nM. Quick and ultrasensitive detection has been achieved by the Synergistic effect (SGE) and AIE from the current approach. The SGSM has been shown to be a novel platform for human health monitoring and pharmaceutical quality control. With broad-ranging practical implications, the combination of AIE and silver dimolybdate nanosheets offers a platform for reliable and ciprofloxacin detection. We believe the SGSM is a role model paper for future nano-biosensor detection methods due to the synergistic effect resulting in the AIE and turn-on sensor approach for many non-fluorescent 2D nanosheets. This can open many new doors for the intensive development of 2D nanosheets for future fluorescent sensors without the need to produce fluorescence by the nanosheet itself.

Transradial Prostatic Artery Embolization as a Salvage Procedure in a Patient With Severe Deformities and Refractory Hematuria of Prostatic Origin

Initial outcomes and surgical techniques of prostatic urethral lift for benign prostatic hyperplasia in Japan.

The prostatic urethral lift (PUL) has been used as a minimally invasive surgery for benign prostatic hyperplasia (BPH) since April 2022 in Japan. This study evaluated the initial outcomes and surgical techniques of PUL for BPH. In this prospective, single-center study, indications were based on the proper use guidelines for PUL in Japan. Preoperative patient status, postoperative progress at 1 and 3 months, and perioperative complications were evaluated. The surgical technique was changed twice, and the subgroup analysis and technique were evaluated. Of the 50 patients who underwent surgeries performed by a single surgeon, the median age and prostate volume were 71 years and 42.0 mL, respectively. Furthermore, the median operative time and number of implants used were 20 min and 5, respectively. No postoperative fever or severe hematuria requiring reoperation occurred. All patients were discharged from the hospital the day following the PUL, as scheduled. Postoperative International Prostate Symptom Score, quality of life score, maximum flow rate, and postvoid residual volume at 1 and 3 months were significantly improved compared with the preoperative values. A significant improvement in maximum flow rate was observed in the subgroup analysis from 1 month postoperatively in the group with an anterior channel creation focus. PUL is effective and safe in cases with prostate volumes of <100 mL. Lifting the bladder neck is important for opening an anterior prostatic urethral channel and improving urinary function during the early postoperative period.

The safety and efficacy of Sotn ureteroscopy for renal and upper ureteral calculi: a prospective multicenter randomized controlled trial.

Sotn ureteroscopy is a new lithotripsy procedure developed on the basis of ureteroscopy and includes a rigid ureteral access sheath, standard mirror, lithotripsy mirror, and Sotn perfusion aspirator. Thus, we performed a prospective multicenter randomized controlled trial comparing the safety and efficacy of Sotn ureteroscopy in the treatment of renal and upper ureteral calculi. In this study, 224 patients with renal and upper ureteral calculi were randomly divided equally into study and control groups from March 2018 to March 2022. All the patients were approved by the hospital ethics committee (proof number: ZF-2018-164-01 and ZF-2018-165-01) of the Second Affiliate Hospital of Guangzhou University of Chinese Medicine in China. The primary outcome was stone-free rate (SFR) assessed by computed tomography on the 1st day and month after treatment and operation duration. The secondary outcome was postoperative complication rate. In total, for upper ureteral calculi, the SFR of 1 day after operation of the Sotn ureteroscopy group was significantly higher than the rigid ureteroscopy group (83.6% vs. 60%, P=0.006). Moreover, operative time (33.7±1.80 vs. 52.9±2.73 min, P<0.005) of the Sotn ureteroscopy group was significantly lower than the rigid ureteroscopy group. Additionally, the SFR of 1 day after operation and operative time for the study group (Sotn ureteroscopy combined with flexible ureteroscopy) and the control group (flexible ureteroscopy alone) were 63.2% and 36.8% (P=0.005), 65.6±4.06 and 80.3±4.91 (P=0.023), respectively. However, there were no significant differences in the SFR of 1 month after operation, success rate of ureteral access sheath placement, and postoperative complications between the two groups (P>0.05). In subgroups with stone diameters ≥1.5 cm and stone CT values ≥1000 Hounsfield units, Sotn ureteroscopy showed more advantages in terms of the SFR of 1 day after operation. Importantly, complications such as ureteral injury, sepsis, fever, and severe hematuria were not statistically different between the two groups (P>0.05). For renal and upper ureteral calculi, Sotn ureteroscopy has the advantage of a higher SFR of 1 day after the operation and a shorter operative time, suggesting that the Sotn ureteroscopy may have further potential applications in clinics.

Distinct characteristics and prognosis of IgA nephropathy patients with nephrotic syndrome: a propensity score-matched cohort study.

IgA nephropathy (IgAN) is the most prevalent primary glomerulonephritis globally. While nephrotic syndrome (NS) is uncommon in IgAN, its significance remains unclear. We conducted a retrospective analysis of 170 IgAN patients, classifying them into NS (n = 85) and non-NS (n = 5) groups. Our study aims to compare their clinical characteristics, treatment responses, and prognoses. Patients were selected based on renal biopsy from 2003 to 2020. Propensity score matching ensured comparability. Clinical, pathological, and immunological data were analyzed. Composite endpoints were defined as end-stage kidney disease (ESKD) or a 30% decline in estimated glomerular filtration rate (eGFR). NS patients showed higher eGFR (74.3 ± 36.8 vs. 61.5 ± 33.6 mL/min.1.73 m2, p = 0.02), severe hematuria (35.0 (4.7,147.5) vs. 4.0 (1.8,45,0) cells/μl, p < 0.001), severe foot process effacement (p = 0.01), and lower C3 levels (1.0 ± 0.3 vs. 1.1 ± 0.2 g/L, p = 0.03). In contrast, the non-NS group had higher BMI (24.3 ± 4.0 vs. 26.8 ± 3.7 kg/m2, p < 0.001) and elevated serum uric acid levels (376 (316,417) vs. 400 (362, 501) mmol/L, p = 0.001), suggesting metabolic factors might contribute to their condition. Both groups exhibited similar MESTC scores. NS patients had higher complete remission rates (26.2% vs. 14.1%, p = 0.04). Cox regression revealed NS independently associated with a higher risk of composite endpoints (HR = 1.97, 95% CI 1.05-3.72, p = 0.04). Linear mixed models did not show significant eGFR trajectory differences. This study has established that IgAN patients with NS exhibit distinct characteristics, including active disease and increased complement activation. NS is independently associated with a poorer prognosis, emphasizing the need for targeted interventions in this subgroup.

The effect of fibrinoid necrosis on the clinical features and outcomes of primary IgA nephropathy

BackgroundTo explore the clinicopathologic features and outcomes of IgAN patients who presented with fibrinoid necrosis (FN) lesions or not and the effect of immunosuppressive (IS) treatment in IgAN patients with FN lesions as well.MethodsThis was a retrospective cohort study with 665 patients diagnosed with primary IgAN from January 2010 to December 2020 in Tianjin Medical University General Hospital and having detailed baseline and follow-up characteristics. Patients were divided into two groups depending on the appearance of FN lesions. Patients with FN lesions were recruited into Group FN1, while patients who were not found FN lesions in their renal biopsy specimens were recruited into Group FN0. Compare the differences between Group FN0 and Group FN1 in baseline clinicopathologic features, treatment solutions and follow-up data as well. To evaluate the impact of different fractions of FN lesions on baseline characteristics and prognosis of IgAN, we subdivided patients in Group FN1 into 3 groups depending on the FN lesions distribution, Mild Group: 0 < FN% < 1/16; Moderate Group: 1/16 < FN% < 1/10; Severe Group: FN% > 1/10. Furthermore, we compared the differences in baseline clinicopathologic features, treatment solutions and follow-up data among these three groups. Kidney endpoint event was defined as patients went into end-stage kidney disease (ESKD), which estimated glomerular filtration rate (eGFR) < 15 ml/min/1.73 m^2, regularly chronic dialysis over 6 months or received renal transplantation surgery. The kidney composite endpoint was defined by a ≥ 30% reduction in eGFR, double Scr increase than on-set, ESKD, chronic dialysis over 6 months or renal transplantation. Compare the survival from a composite endpoint rate in different groups by Kaplan-Meier survival curve. The univariate and multivariate Cox models were used to establish the basic model for renal outcomes in patients with FN lesions.Results(1) A total of 230 patients (34.59%) were found FN lesions in all participants. Patients with FN lesions suffered more severe hematuria than those without. On the hand of pathological characteristic, patients with FN lesions showed higher proportions of M1, E1, C1/C2 and T1/T2 lesions compared with those without FN lesions. (2) The 1-year, 3-year, and 5-year survival of the composite endpoint were lower in the FN1 group than FN0 group. (3) After adjusting for clinicopathological variables, the presence of FN lesions was a significantly independent risk factor for composite endpoint. By using multivariate Cox regression analyses, we also found when the fraction of FN lesions exceeded 10%, the risk of progression into composite endpoint increased 3.927 times.ConclusionFibrinoid necrosis of capillary loops is an independent risk factor of poor renal outcomes. More effective treatment should be considered for those who had FN lesions.

The value of ATAD3A as a potential biomarker for bladder cancer.

Bladder cancer (BCa) is a highly malignant tumor, and if left untreated, it can develop severe hematuria and tumor metastasis, thereby endangering the patient's life. The purpose of this paper was to detect the expression of ATAD3A in BCa and research the relationship between ATAD3A and pathological features of bladder cancer and the prognosis of patients. First, the expression of ATAD3A in BCa and normal bladder tissues was analyzed based on the UALCAN and Oncomine public databases. Second, 491 cases of surgically resected bladder cancer specimens and 110 cases of normal adjacent tissues were immunohistochemically stained. The expression of ATAD3A was quantified, and the value and prognosis of ATAD3A as a biomarker of BCa were evaluated. The expression of ATAD3A in bladder cancer tissues was higher than that in normal bladder mucosa. High expression of ATAD3A was correlated with patient age, tumor size, number of tumors, distant metastasis, lymph node metastasis, lymphovascular invasion, and TNM stage (p < 0.05). Overexpression of ATAD3A is closely related to cancer patient survival. The mean survival time of bladder cancer patients with high ATAD3A expression was shorter than those with low ATAD3A levels. According to the relative comparing result, the high ATAD3A expression herald reduced overall survival in BCa patients. The abnormal overexpression of ATAD3A may be related to the initiation and progress of bladder cancer. The upregulation of ATAD3A can be used as an effective indicator to diagnose bladder cancer and predict tumor progression. Furthermore, the combination of information from public databases and the results of clinical sample analysis can help us better understand the mechanism of action of molecular oncogenes in bladder cancer.

The correlation between trajectories of serum C3 variability and clinical course in Pediatric-onset systemic lupus erythematosus.

The aim of this study is to investigate the usefulness which 2-year trajectories of C3 variability have in predicting clinical remission and systemic corticosteroids (SCS) use in pediatric patients with systemic lupus erythematosus (pSLE). We recruited 189 confirmed pSLE patients from the electronic database of our hospital, all had undergone SCS treatment. The follow up period was 4.17-14.83 years. We used Group-Based Trajectory modeling to divide the patients into four different trajectory groups by their initial 2-year C3 variability. We divided the patients into groups A, B or C by their clinical course and SCS use. Statistical methods included Kruskal-Wallis and Chi-square tests and logic regression test. There were 4 separate trajectories. The distribution of groups A, B and C in these 4 trajectories showed a significant difference (p=0.005). Initial C3 and C4 levels in these 4 revealed significant differences (p≦0.001, p≦0.016). When compared to other trajectories, trajectory1 showed a higher risk for persistent SCS use (p<0.05). The distributions of severe clinical manifestations, including proteinuria, hematuria, CNS involvement and thrombocytopenia were different in these 4 trajectories (p=0.003). Nevertheless, none of the above manifestations contributed to the risk of persistent SCS use. We have found 4 distinct C3 trajectories in pSLE patients. Distributions of clinical outcome groups were different in these 4 trajectories. Patients with trajectory1 displayed a higher risk for persistent SCS use, thus an earlier institution of immunosuppressant(s) and biological agents can be considered for these children.

Severe Gross Hematuria Associated with Antithrombotic Drugs: Management and Impact on Prescription Thereafter

Anfibatide is a synthetic antiplatelet thrombolysin derived from snake venom and is proposed to treat ischemic stroke and cerebral ischemia-reperfusion injury. Current standard treatments for ischemic stroke include the administration of rt-PA, a thrombolytic agent, or endovascular removal of thrombi. However, the post-treatments are often associated with the occlusion of vessels due to a lack of antiplatelet and unrecovered vessel injury. Anfibatide, as a GPIba antagonist that interrupts the initiation of platelet aggregation caused by GPIba-vWF binding, becomes a potential novel candidate for treating ischemic stroke due to its antiplatelet and antithrombosis effects. Key findings show that Anfibatide can significantly reduce microthrombus formation in cerebral vessels and reduce neuron apoptosis due to the release of pro-inflammatory mediators caused by ischemia or Ischemia-Reperfusion (I/R) injury. Significant improvement in neurological scores and reversal of brain structure alterations are observed in the Anfibatide-treated ischemic animal models. To facilitate the clinical development of Anfibatide, this paper aims to summarize the completed preclinical studies and the Phase I clinical trial results of anfibatide to evaluate the risks and therapeutic potentials of Anfibatide in ischemic patients.

Primary high-grade urothelial carcinoma of prostate with prostatic hyperplasia: a rare case report and review of the literature

Background Primary urothelial carcinoma in the prostate (UCP) is extremely rare and occurs most frequently in the bladder. There are only dozens of primary cases reported in the literature. Here, we describe a rare case of primary UCP and review the literature. Case presentation A 67-year-old widowed male, was referred to our hospital due to the frequency, and urgency of dysuria. Magnetic resonance imaging (MRI) examination revealed prostate size was about 57 mm × 50 mm × 54 mm, increased prostatic transitional zone, and surrounding of prostatic duct indicate bar isointense T1, short T2, hyperintense DWI, and hyposignal ADC (PI-RADS 3); posterior of peripheral zone indicate patchy isointense T1, short T2, hyperintense DWI, and hyposignal ADC (PI-RADS 5). Subsequently, the patient underwent a transrectal prostate biopsy. Histopathological and immunohistochemical (IHC) assessments showed prostatic high-grade urothelial carcinoma with benign prostatic hyperplasia. Finally, the patient underwent laparoscopic radical prostatectomy. Four months after surgery, CT plain and enhanced scan revealed thickening of the bladder wall. On further workup, cystoscopy revealed lymphoid follicular changes in the cut edge of the radical prostatectomy, and cystoscopic biopsies showed the malignant tumor. Conclusions Prostatic urothelial carcinoma should always be considered if the patient with severe lower urinary tract symptoms or hematuria, PSA, and digital rectal examination without abnormalities, without a personal history of urothelial cancer, but contrast-enhanced MRI showed the lesion located in the prostate. As of right now, radical surgical resections remain the most effective treatment. The effectiveness of neoadjuvant or adjuvant chemotherapy is still controversial.
