'Nocturomics': transition to omics-driven biomarkers of nocturia, a systematic review and future prospects.

OBJECTIVE: To systematically review studies that investigated different biomarkers of nocturia, including omics-driven biomarkers or 'Nocturomics'. MATERIALS AND METHODS: PubMed® , Scopus® , and Embase® were searched systematically in May 2022 for research papers on biomarkers in physiological fluids and tissues from patients with nocturia. A distinction was made between biomarkers or candidates discovered by omics techniques, referred to as omics-driven biomarkers, and classical biomarkers, measured by standard laboratory techniques and mostly thought from pathophysiological hypothesis. RESULTS: A total of 13 studies with 18 881 patients in total were included, eight of which focused on classical biomarkers including: atrial natriuretic peptide (ANP), B-type natriuretic peptide (BNP), C-reactive protein (CRP), aldosterone, and melatonin. Five were 'Nocturomics', including one that assessed the microbiome and identified 27 faecal and eight urinary bacteria correlated with nocturia; and four studies that identified candidate metabolomic biomarkers, including fatty acid metabolites, serotonin, glycerol, lauric acid, thiaproline, and imidazolelactic acid among others. To date, no biomarker is recommended in clinical practice. Nocturomics are in an embryonic phase of conception but are developing quickly. Although candidate biomarkers are being identified, none of them are yet validated on a large sample, although some preclinical studies have shown a probable role of fatty acid metabolites as a possible biomarker of circadian rhythm and chronotherapy. CONCLUSION: Further research is needed to validate biomarkers for nocturia within the framework of a diagnostic and therapeutic precision medicine perspective. We hope this study provides a summary of the current biomarker discoveries associated with nocturia and details future prospects for omics-driven biomarkers.

Top 50 most cited articles about female sexual dysfunction: a bibliometric analysis.

INTRODUCTION: Female sexual dysfunction (FSD) consists of low libido, sexual arousal problems, anorgasmia, and dyspareunia. Sexual function is an important aspect of life for many women and is closely correlated with overall well-being. FSD is often underrepresented in the academic space when compared with male sexual disorders, such as erectile dysfunction. As FSD spans many fields (eg, urology, gynecology, psychology), bibliometric analyses are an important resource to highlight landmark articles. OBJECTIVES: To identify key articles about FSD by citation number and bibliometric analysis to facilitate future scholarly efforts into more FSD research. METHODS: We searched for articles in the Web of Science Core Collection between 1900 and 2023 using terms specific to FSD. We identified relevant FSD articles and selected the top 50 most cited. A bibliometric analysis was performed to collect and analyze data about title, authorship, publication year, citation number, journal and impact factor, country and institution, study type, citation index, specialty, and conflict of interest. RESULTS: An overall 6858 results were identified. The top 50 most cited articles were published between 1997 and 2014 in 12 countries, across 32 institutions, and in 20 journals. The United States produced the most articles. The Journal of Sexual Medicine published the most articles. The mean number of citations per article was 351.64. Observational studies were most common. More than half were sponsored. Of all the specialties, most articles were categorized as urology and nephrology. Research about FSD has been much less impactful than research about male sexual dysfunction, possibly owing to stigma and decreased clinical training. CONCLUSION: As FSD covers many fields, bibliometric analyses are invaluable to understand the vast body of knowledge. We hope that this research emphasizes the lack of attention that FSD has had and that it provides health care professionals with a valuable tool to understand the trajectory of FSD to guide future education efforts.

Top 50 Most Cited Articles About OAB: A Bibliometric Analysis.

OBJECTIVE: To identify key articles about overactive bladder (OAB) using citation number and bibliometric analysis. METHODS: We searched for articles in the Web of Science Core Collection between 1900 and 2022 using terms specific to OAB. We identified relevant OAB articles and selected the top 50 most cited. A bibliometric analysis was performed to collect and analyze data about authorship, title, publication year, total citations, journal, journal impact factor, country, institution, study type, citation index, conflict of interest (COI), and conclusions. RESULTS: A total of 12,200 records were identified. The top 50 most cited articles were published between 1997 and 2015 in nine countries, across over 30 different institutions, and in 19 journals. The country, institution, and journal which produced the greatest number of articles were the USA, Southmead General Hospital in England, and BJU International, respectively. The mean number of citations per article was 365.66. Observational studies and clinical trials were the most common. Most articles were published in 2006 and were sponsored. The most cited article also had the most citations per year. This study is limited by using a single database and a single parameter as a proxy for paper importance. CONCLUSION: Bibliometric analyses are an important resource for clinicians to understand the body of knowledge of OAB by identifying landmark papers. This objective approach to literature review can facilitate future research and scholarly efforts.

Impact of COVID-19 on Online Interest in Urologic Conditions: An Analysis of Google Trends.

Background With COVID-19 leading to several isolation measures for preventative care, health care utilization, especially within urology, decreased substantially. The impact of COVID-19 on the population's interests in urologic conditions remains to be established. By using the platform of Google Trends, which allows search behaviors and interest in healthcare topics to be quantified over time, we investigated the impact of COVID-19 on online search behaviors relating to common urologic conditions in the US. Methods The platform of Google Trends was utilized to analyze online interest in twelve common urologic conditions in the US from October 1, 2018 to August 1, 2021 (divided into "pre-COVID" and "COVID" periods at March 1, 2020). Search volume index (SVI), a measure of relative search volume on Google, data sets for the US, top queried and populated states, rising queries, and top queries were retrieved and analyzed for all conditions. Pre-COVID and COVID median SVIs were compared using the Mann Whitney U test, and correlations were analyzed using Spearman's rank-order correlation test. Results For all twelve urologic conditions, rising and top queries were often related to symptoms, treatments, and COVID-19. COVID showed higher SVIs for erectile dysfunction (p=0.04) and lower SVIs for bladder cancer (p<0.01), hematuria (p<0.01), kidney cancer (p<0.01), kidney stones (p=0.03), and prostate cancer (p<0.01). Correlations to COVID-19 searches were seen for bladder cancer (RS=-0.36, p<0.01), erectile dysfunction (RS=0.20, p=0.04), hematuria (RS=-0.31, p<0.01), overactive bladder (RS=-0.23, p=0.04), and prostate cancer (RS=-0.33, p<0.01). No correlations were found for benign prostatic hyperplasia, interstitial cystitis, low testosterone, urinary incontinence, and urinary tract infections. Conclusions Online interest in many urologic conditions, especially cancers, decreased during COVID. Given the internet's increasing role in healthcare, a reduced interest could translate to delayed diagnosis and treatment of these conditions. Only erectile dysfunction showed increasing interest, potentially due to research or misinformation linking it to COVID-19.

Oxidative Stress Biomarkers in Age-Related Lower Urinary Tract Disorders: A Systematic Review.

PURPOSE: To conduct a systematic review of preclinical and clinical peer-reviewed evidence linking alterations in oxidative stress biomarkers or outcome measures that were also prevalent in specific age-related lower urinary tract (LUT) disorders. METHODS: PubMed, Scopus, CINAHL, and Embase were searched for peer-reviewed studies published between January 2000 and March 2021. Animal and human studies that reported on the impact of oxidative stress in age-related LUT disorders through structural or functional changes in the LUT and changes in biomarkers were included. The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) protocol was followed. RESULTS: Of 882 articles identified, 21 studies (13 animal; 8 human) met inclusion criteria. Across LUT disorders, common structural changes were increased bladder and prostate weights, ischemic damage, nerve damage and detrusor muscle hypertrophy; common functional changes included decreased bladder contraction, increased bladder sensation and excitability, decreased perfusion, and increased inflammation. The disorders were associated with increased levels of biomarkers of oxidative stress that provided evidence of either molecular damage, protective mechanisms against oxidative stress, neural changes, or inflammation. In all cases, the effect on biomarkers and enzymes was greater in aged groups compared to younger groups. CONCLUSION: Increased oxidative stress, often associated with mitochondrial dysfunction, plays a significant role in the pathogenesis of age-related LUT disorders and may explain their increasing prevalence. This systematic review identifies potential markers of disease progression and treatment opportunities; further research is warranted to evaluate these markers and the mechanisms by which these changes may lead to age-related LUT disorders.

An Analysis of Google Trends During COVID-19: Determining Public Urological Cancer Concerns.

Background The COVID-19 pandemic put a massive strain on the healthcare system as patients avoided the hospital, elective cases were postponed, and general medical anxiety was increased. We aimed to capture public interest in urological cancers during this massive shock to the medical field. Methodology A total of 12 keywords related to the three most prevalent urological cancers (prostate, bladder, and kidney) were searched using Google Trends from 2018 to 2022. The search volume index of these 12 keywords was extracted to assess public interest before and after the pandemic. Results There was a reduction in search volume for "prostate, bladder, and kidney cancer" and "kidney cancer treatment" after the postponement of elective surgeries. However, there was an increase in search volume for "prostate, bladder, and kidney cancer survival rates" and "prostate cancer symptoms" after this period. There was no change in search volume for bladder cancer symptoms, bladder cancer treatment, or kidney cancer symptoms. Conclusions Public interest in urological cancers decreased after COVID, while interest in survival rates across all three cancers increased. Future research is needed to investigate the effects of changing priorities and delays in medical care on patients' experiences with urological cancers.

Transition from Childhood Nocturnal Enuresis to Adult Nocturia: A Systematic Review and Meta-Analysis.

PURPOSE: Current literature has suggested a relationship between nocturnal enuresis (NE) in childhood and the development of nocturia later in life as both disorders have similar underlying etiologies, comorbidities, and treatments. The objective was to synthesize the available evidence on the association between childhood NE and later presentation of nocturia. METHODS: PubMed, CINAHL, Scopus, and Google Scholar were searched for peer-reviewed studies published between January 1980 and April 2021. Case-control and cohort studies that reported on childhood NE and current nocturia were included. The PRISMA protocol was followed (PROSPERO ID: CRD42021256255). A random-effects model was applied to calculate the pooled odds ratio (OR) and 95% confidence interval (CI). Risk of bias was assessed using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) criteria and with a funnel plot. RESULTS: Of the 278 articles identified, 8 studies met inclusion criteria. The 6 case-control and 2 prospective cohort studies resulted in a total sample size of 26,070 participants. In a random-effect pooled analysis, childhood NE was significantly associated with the development of nocturia (OR: 1.75, 95% CI: 1.11-2.40). Significant heterogeneity (I2 = 92.7%, p < 0.01) was identified among the included studies, which was reflected in an asymmetrical funnel plot. NE and nocturia have similar underlying etiologies of hormonal abnormalities, sleep disorders, physiological disorders, and psychological disorders. CONCLUSION: The history of childhood NE is significantly associated with nocturia later in life. The data in this meta-analysis support this transition and identify potential similarities between the two disorders. The sparse number of articles relevant to this topic is a strong indicator of the need for more work on this transition from childhood to maturity. More studies are warranted to further explore the association between NE and nocturia.
