    Abstract BackgroundPediatric urological diseases pose serious threats to children's physical and mental health. The COVID-19 pandemic has resulted in poor pediatric outcomes for cryptorchidism, hypospadias, and testicular torsion. Presently, many people tend to seek health information via social media platforms. This study aims to quantitatively assess the quality of videos as an information source for pediatric urology in mainland China.MethodsIn this cross-sectional study, a search was performed on social media platforms (Tiktok, Bilibili, and Weibo) with the search terms “cryptorchidism”, “hypospadias”, and “testicular torsion”. The first 30 results with any search term listed by relevance were selected in each platform. Video features (duration, number of likes, comments, and shares) and video sources were collected. Each video included in the study was assessed using DISCERN, Journal of the American Medical Association (JAMA) Benchmark Criteria, and Hexagonal Radar Schema. A correlation analysis was performed considering video features, video source, DISCERN scores and JAMA scores.ResultsA total of 152 videos were included and analyzed. The majority of videos were from physicians (65.8%). According to the DISCERN classification, most videos were rated as “very poor” (48.0%) and “poor” (36.8%). The mean DISCERN and JAMA scores were 36.56 and 2.68, respectively. The duration of videos uploaded by physicians was the shortest (P < 0.001). The video source had no relevance to numbers of “likes”, “comments”, “shares”, DISCERN scores, and JAMA scores (all P-values > 0.05). Other than video duration (P < 0.001), there was no statistically significant difference between groups for any of the recorded or calculated video data (all P values > 0.05). Hexagonal Radar Charts showed the severe imbalance and deficiency of video information. In general, Tiktok videos with the shortest duration received the most numbers of “likes”, “comments”, and “shares”, whereas the overall quality of videos on Weibo was relatively ...

    Abstract Background: Pediatric urological diseases pose serious threats to children's physical and mental health. The COVID-19 pandemic has resulted in poor pediatric outcomes for cryptorchidism, hypospadias, and testicular torsion. Presently, many people tend to seek health information via social media platforms. This study aims to quantitatively assess the quality of videos as an information source for pediatric urology in mainland China.
    Methods: In this cross-sectional study, a search was performed on social media platforms (Tiktok, Bilibili, and Weibo) with the search terms "cryptorchidism", "hypospadias", and "testicular torsion". The first 30 results with any search term listed by relevance were selected in each platform. Video features (duration, number of likes, comments, and shares) and video sources were collected.

    Conclusions: Despite most of the videos on social media platforms being uploaded by medical authors, the overall quality was poor. The misleading, inaccurate and incomplete information may pose a health risk to the viewers, especially during the COVID-19 pandemic. Much effort needs to be undertaken to improve the quality of health-related videos regarding pediatric urology.

    Abstract Background:Testicular torsion is an acute scrotal disease requiring urgent management, and the COVID-19 pandemic has been demonstrated to lead to poor outcomes for this disease. Presently, many people tend to seek health information via YouTube. This study aims to quantitatively assess the quality of English YouTube video content as an information source of testicular torsion.MethodsIn this cross-sectional study, a search was performed with the search term “testicular torsion” on YouTube, and the first 100 videos listed by relevance were selected for our analysis. Duplicate, non-English, videos without audio and surgical videos were excluded. Video features (duration, number of days online, views, likes, comments), source of the video, and author's country were collected. Each video included in the study was assessed using DISCERN and Journal of the American Medical Association (JAMA) Benchmark Criteria. A correlation analysis was performed considering video features, video source, DISCERN scores and JAMA scores.ResultsA total of 66 videos were included and analyzed. The most common video content was general information, including etiology, symptoms, and treatment. The majority of videos were from education and training websites (30%), physicians (23%), and independent users (21%). The mean DISCERN and JAMA scores were 36.56 and 2.68, respectively. According to DISCERN, the quality of video uploaded by physicians was relatively high (P < 0.001), and the quality of video uploaded by independent users was relatively low (P < 0.001). The JAMA score had no relevance to the video source (P = 0.813). The correlation between the video features, DISCERN and JAMA scores was controversial by different assessment methods.ConclusionsDespite most of the videos on YouTube being uploaded by medical or education-related authors, the overall quality was poor. The misleading, inaccurate and incomplete information may pose a health risk to the viewers, especially during the COVID-19 pandemic. Much effort needs to be ...

    Abstract Polystyrene microplastics (PS-MPs) can threaten human health, especially male fertility. However, most existing studies have focused on the adulthood stage of male reproduction toxicity caused by relatively short-term PS-MP exposure. This study aimed to investigate the toxic effect of PS-MPs on testicular development and reproductive function upon prenatal and postnatal exposure. Pregnant mice and their offspring were exposed to 0, 0.5 mg/L, 5 mg/L, and 50 mg/L PS-MPs through their daily drinking water from gestational day 1 to postnatal day (PND) 35 or PND70. We found that PS-MP exposure induced testis development disorder by PND35 and spermatogenesis dysfunction by PND70. By combining RNA sequencing results and bioinformatics analysis, the hormone-mediated signaling pathway, G1/S transition of the mitotic cell cycle, coregulation of androgen receptor activity, and Hippo signaling pathway were shown to be involved in testis development on PND35. The meiotic cell cycle, regulation of the immune effector process, neutrophil degranulation, and inflammation mediated by chemokine and cytokine signaling pathways were associated with disturbed spermatogenesis on PND70. These findings show that prenatal and postnatal exposure to PS-MPs resulted in testis development disorder and male subfertility, which may be regulated by the Hippo signaling pathway and involve an immune reaction.

    Abstract Background: It has been observed that cancer and venous thromboembolism (VTE) are associated, but anticancer therapy may violate the causality. Therefore, this study aimed to elucidate the causal relationship of various cancers to VTE using Mendelian randomization (MR).
    Methods: Three MR methods were used to estimate causal effects: Inverse variance weighted (IVW), MR-Egger and weighted median. Sensitivity analyses included Cochran's
    Results: The primary IVW approach showed that non-Hodgkin's lymphoma (NHL) might increase the risk of VTE (odds ratio [OR]: 1.20, 95% confidence interval [95% CI]: 1.00-1.44,
    Conclusions: Our findings suggested that genetically predicted NHL was associated with higher VTE risk, whereas melanoma had lower VTE risk compared with other site-specific cancers. Moreover, this study suggested that anticancer therapy and increased extensive examination might play a more important role in VTE development than the nature of cancer.

    Abstract Background: Hypospadias is one of the most common congenital diseases of the genitourinary system in children. The European Association of Urology (EAU) Guidelines recommend that children undergoing hypospadias surgery should be between 6 and 18 months. In China, where many children have hypospadias, it remains unknown whether clinical characteristics, socioeconomic factors and COVID-19 were associated with delayed surgery in children with hypospadias.
    Methods: We retrospectively analyzed children with hypospadias who underwent primary surgery at the Department of Pediatric Urology in Guangzhou Women and Children's Medical Center between January 2010 and October 2021. Patients who had two-stage surgery or a second round of surgery due to complications were excluded to eliminate data duplication. The clinical characteristics and demographic information were collected. We defined delayed surgery as primary surgery performed after 18 months following the EAU Guidelines.
    Results: A total of 4439 children diagnosed with hypospadias were included in the study. The median age (29.1 ± 16.7 months) of surgery for hypospadias in our study was much higher than the recommended age reported in the EAU guidelines, and 76.6% of the children underwent surgery after the age of 18 months. Children without comorbidities including cryptorchidism (odds ratio [OR] = 1.562; 95% confidence interval [CI] 1.199-2.034; p = 0.001), prostatic cyst (OR = 2.613; 95% CI 1.579-4.324; p < 0.001), penile hypoplasia (OR = 1.778; 95% CI 1.225-2.580; p = 0.002), inguinal hernia (OR = 2.070; 95% CI 1.394-3.075; p < 0.001), and penoscrotal transposition (OR = 4.125; 95% CI 1.250-13.619; p = 0.020) were more likely to receive delayed surgery. Living in a low economic area (OR = 1.731; 95% CI 1.068-2.806; p = 0.026) or not close to a main medical center (OR = 1.580; 95% CI 1.370-1.824; p < 0.001) was highly associated with delayed surgery. The proportion of children undergoing delayed surgery and the median age of surgery during the COVID-19 pandemic were significantly higher than those before the COVID-19 pandemic (p = 0.004 and < 0.001, respectively).
    Conclusions: Most children with hypospadias received delayed surgery (surgical age > 18 months). Comorbidities, living in a low economic area, too far from a main medical center and the COVID-19 pandemic were highly associated with delayed surgery. It is vital to improve the public awareness of hypospadias and strengthen the re-education of primary community doctors to reduce delayed surgery.

    Abstract Several studies have identified the critical role of calcium-sensing receptors (CaSRs) in cardiac ischaemia/reperfusion injury and cardiac hypertrophy and have demonstrated that CaSRs induce myocardial apoptosis by activating MAPKs. Using acute myocardial infarction rat models, we found that a combination therapy of CaSR inhibition and embryonic stem cell (ESC) transplantation after acute myocardial infarction (AMI) leads to a dramatic reduction in the infarct size; a significant increase in the maximum rising and falling rate (+dp/dtmax and -dp/dtmax, respectively) of left ventricular pressure; a significant decrease in left ventricular end-diastolic pressure; a significant decrease in the mRNA expression level of CaSR, Bax, Bcl-2, cleaved caspase-3, cleaved caspase-9, p-ERK, p-JNK and p-P38 protein together with apoptosis indexes in the C and E groups; and a significant decrease in cTnT levels as well as LDH and CK activity. These findings indicate that cardiac function could be enhanced significantly by combination therapy with CaSR inhibition and ESC transplantation; the effect was better than ESC transplantation alone, and the mechanism might be associated with a reduction in cell apoptosis via the inhibition of the MAPK pathway. Apoptosis could be reduced through CaSR, which regulates the MAPK pathway and apoptosis-related protein. Our study indicated that CaSR inhibitors have a pivotal role in the treatment of AMI.

    Abstract Background: Secondary jejunal tumor from renal cell carcinoma (RCC) is extremely rare in clinical practice and is easily missed and misdiagnosed because of the low incidence and atypical symptoms.
    Case summary: A 38-year-old male patient was diagnosed pathologically with left RCC after radical nephrectomy in 2012. The patient then suffered multiple lung metastases 2 years later and was treated with oral sorafenib without progression for 6 years. In 2020, an emergency intestinal segmental resection due to intestinal obstruction was required, and postoperative pathology confirmed a jejunal secondary tumor from RCC. The patient had a smooth recovery following surgery. Three months after surgery, the patient was diagnosed with left adrenal metastasis, and subsequent sintilimab therapy has stabilized his condition.
    Conclusion: This report is written to remind urologists and pathologists of the potential for small intestinal secondary tumors when a patient with a history of RCC seeks treatment for digestive symptoms. Enteroscopy and abdominal contrast-enhanced computed tomography are essential means of examination, but severe cases require immediate surgical intervention despite the lack of a preoperative examination to distinguish tumor attributes.

    Abstract Air-unstable magnetic aluminum phthalocyanine (AlPc) molecules are prepared by an on-surface metalation reaction of phthalocyanine with aluminum (Al) atoms on Au(111) in ultrahigh vacuum. Experiments and density functional theory calculations show that an unpaired spin is located on the conjugated isoindole lobes of the molecule rather than at the Al position.
