Background: Complex nexuses between obesity and chronic kidney disease (CKD) have been reported. Nevertheless, the link between the body roundness index (BRI), an indicator utilized to measure body fat distribution, and CKD risk has been unexplored., Methods: We utilized publicly available data from ten survey cycles (1999-2018) of the National Health and Nutrition Examination Survey (NHANES) in the United States. We examined the association between BRI and CKD risk using multivariable logistic regression, subgroup analysis, interaction tests, and smooth curve fitting., Results: The study ultimately involved 41,953 participants, 3,123 (7.44%) of whom had CKD. Multivariable logistic regression, adjusted for covariates, identified high BRI levels in quartile 4 as a risk factor for CKD (OR = 1.30, 95% CI 1.12-1.50, P = 0.0005). This association remained consistent across subgroups (P for interaction > 0.05). Smoothed curve fitting exhibited a roughly linear positive correlation between BRI and CKD., Conclusion: According to our study, BRI was related to CKD in a roughly linear way, suggesting a novel indicator for improving prevention and treatment for the CKD population. Nevertheless, additional research is needed to identify the association., (© 2024. The Author(s), under exclusive licence to Springer Nature B.V.)

Previous research has suggested that circulating inflammatory proteins are associated with benign prostatic disease (BPD). This Mendelian randomization (MR) study was conducted to further investigate the causal relationship between 91 inflammatory proteins and BPD. Genome-wide association study (GWAS) summarized data of benign prostatic hyperplasia (BPH) and prostatitis were obtained from the FinnGen Biobank. The latest study offered the GWAS data on 91 proteins related to inflammation. We performed a bidirectional MR to investigate the causal association between inflammatory proteins and BPD. The outcomes of the IVW method indicated that decreased levels of circulating interleukin-17 C (IL-17 C) (OR = 0.92, 95%CI = 0.85-0.99, p-value = 0.0344) were suggestively associated with a higher risk of BPH and elevated levels of interleukin-10 receptor subunit alpha (IL-10RA) (OR = 1.24, 95%CI = 1.05-1.47, p-value = 0.0132) and urokinase-type plasminogen activator (uPA) (OR = 1.13, 95%CI = 1.00-1.28, p-value = 0.0421) were suggestively related to a higher risk of prostatitis. Furthermore, reverse MR revealed that BPH may promote the expression of circulating factors, including natural killer cell receptor 2B4 (CD244) (OR = 1.07, 95%CI = 1.01-1.13, p-value = 0.0192), T-cell surface glycoprotein CD6 isoform (CD6) (OR = 1.07, 95%CI = 1.01-1.13, p-value = 0.0192), and leukemia inhibitory factor receptor (LIF-R) (OR = 1.07, 95%CI = 1.01-1.15, p-value = 0.0163). Moreover, the results of sensitivity analyses indicate that heterogeneity and horizontal pleiotropy are unlikely to distort the findings. The results of this study indicate a potential association between circulating inflammatory proteins and BPD, which may become new diagnostic indicators or drug targets for clinical application in the prevention and treatment of BPD. However, further investigation is required., (© 2024. The Author(s).)

Background: The impact of micronutrients, including vitamins and minerals, on different kidney diseases has been reported in some observational studies; however, their causal relationship remains uncertain. We aimed to ascertain the causal genetic relationships between micronutrients and different kidney diseases using the Mendelian randomization (MR) method., Methods: Instrumental variables (IVs) for genetically predicting calcium (Ca), iron (Ir), Zinc (Zn), selenium (Se), copper (Cu), vitamin D (Vit D), and vitamin C (Vit C) levels in humans were obtained, and a bidirectional two-sample MR was used to examine potential associations between the levels of these seven micronutrients and the risk of seven different kidney diseases including hypertensive renal disease, diabetic nephropathy, IgA nephropathy, membranous nephropathy, cystic nephropathy, chronic kidney disease (CKD), and chronic tubulo-interstitial nephritis. Five different MR analyses were conducted, with the main method being the inverse variance-weighted (IVW) method. Moreover, sensitivity analyses were performed to assess heterogeneity and potential pleiotropy., Results: The IVW method revealed that Ca levels were associated with a decreased risk of hypertensive renal disease (OR = 0.61, 95% CI: 0.40-0.93, p -value = 0.022), and Se levels were associated with a decreased risk of hypertensive renal disease (OR = 0.72, 95% CI: 0.53-0.99, p -value = 0.040), diabetic nephropathy (OR = 0.83, 95% CI: 0.73-0.93, p -value = 0.002), and CKD (OR = 0.87, 95% CI: 0.77-0.99, p -value = 0.028). Conversely, Vit D levels were associated with an increased risk of polycystic kidney disease (OR = 1.76, 95% CI: 1.15-2.69, p -value = 0.0095). In addition, no potential causal relationship was found between vitamin C levels, iron levels, zinc levels, and copper levels and different kidney diseases. Meanwhile, inverse Mendelian randomization showed no potential causal relationship between different chronic kidney diseases and micronutrients. The Cochrane's Q test, MR-Egger regression, and MR-PRESSO did not suggest heterogeneity and pleiotropy, providing evidence of the validity of the MR estimates., Conclusion: Our results indicate a cause-and-effect connection between micronutrients and certain kidney diseases, but additional study is required to provide more conclusive evidence. This research has the potential to assist clinicians in managing the consumption of specific micronutrients among individuals with chronic kidney diseases, as well as in promoting disease prevention among both healthy populations and those who are susceptible to chronic underlying conditions., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Shi, Cao, Zeng, Wu and Wang.)

Environmental tobacco smoke (ETS) exposure has been shown to be associated with a variety of diseases, but evidence regarding the association between it and urinary incontinence (UI) is limited. Cotinine, a metabolite of nicotine in the human body, can more accurately quantify the level of human exposure to tobacco smoke. The study utilized data from seven survey cycles (2007-March 2020 Pre-pandemic) of the National Health and Nutrition Examination Survey (NHANES) program. Weighted multivariable logistic regression analysis, subgroup analysis, interaction tests, smooth curve fitting, and threshold effect models were used to analyze the relationship between serum cotinine and UI. Additionally, a 1:1 nearest neighbor propensity score matching (PSM) method was employed to minimize the impact of confounding factors. Before and after PSM, serum cotinine levels were higher in individuals with UI than those without (P < 0.05). Both before and after PSM, UI was positively correlated with serum cotinine levels, with a significantly increased risk of urinary incontinence when serum cotinine levels were in the Q3 range (before PSM: OR = 1.89, 95% CI = 1.59-2.24; after PSM: OR = 1.60, 95% CI = 1.28-2.00). Smooth curve fitting before and after PSM showed an approximate J-shaped non-linear dose-response relationship between log-transformed serum cotinine levels and UI. This study indicates that among American adults, there is a positive relationship between serum cotinine levels and UI, which is also significant in self-reported non-smoking populations. Therefore, reducing exposure to environmental tobacco smoke (e.g., avoiding second-hand smoke) in work and daily life may help alleviate the occurrence of UI, and serum cotinine levels have the potential to be a tool for predicting the degree of risk of developing UI., (© 2024.

The human gut microbiome (GM) impacts various physiological processes and can lead to pathological conditions and even carcinogenesis if homeostasis is disrupted. Recent studies have indicated a connection between the GM and prostatic disease. However, the underlying mechanisms are still unclear. This review aims to provide a summary of the existing information regarding the connection between the GM and various prostatic conditions such as chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), benign prostatic hyperplasia (BPH), and prostate cancer (PCa). Furthermore, the review aims to identify possible pathogenic mechanisms and suggest potential ways of targeting GM to prevent and treat prostatic disease. Due to the complexity of the mechanism between GM and prostatic diseases, additional research is required to comprehend the association between the two. This will lead to more effective treatment options for prostatic disease., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Cao, Zhang, Wang, Wang, Shi, Wu, Du, Zhang, Gou, Zhou and Wang.)

Background: Benign prostatic hyperplasia (BPH) is a common health disorder of the male genitourinary system with a high prevalence, especially among middle-aged and older adults, which seriously affects men's quality of life. Inflammatory markers derived from complete blood cell count (CBC) have previously been considered a prognostic indicator for various diseases, but little is known about their relationship with BPH. This study evaluated the relationship between complete blood cell count (CBC)-derived inflammatory biomarkers and BPH., Methods: Data for this cross-sectional study were gathered from the National Health and Nutrition Examination Survey (NHANES) between 2001 and 2008. Using multiple logistic regressions, the study examined the association between benign prostatic hyperplasia(BPH) and Inflammatory biomarkers derived from blood cell counts such as neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), Systemic Inflammatory Response Index (SIRI) and Systemic Immunoinflammatory Index (SII)., Results: 3,919 participants were included, with a median age of 61.00 (52.00-71.00) years old. Among them, 609 participants had benign prostatic hyperplasia, with a prevalence of 15.54%. Upon accounting for confounding factors, the study revealed a positive correlation between the plurality of BPH PLR and SII. However, MLR, NLR, and SIRI did not significantly correlate with the prevalence of BPH (p>0.05). In contrast to the lowest quartile, higher quartiles of PLR (OR = 1.93[1.38-2.69]) and SII (OR = 1.71[1.22-2.40]) were linked to an elevated risk of BPH. Interaction tests showed that age, body mass index, hypertension, diabetes, smoking, and drinking had no significant effect on this positive correlation (p for interaction>0.05). In addition, we found a roughly linear association between SII, PLR, and BPH using smoothed curve fitting., Conclusions: According to our research, high levels of PLR and SII are positively linked with an increased risk of BPH in middle-aged and elderly individuals in the United States. The results compensate for previous studies that still need to be validated with larger prospective cohorts., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Shi et al.

Objectives: The relationship between cathepsins and prostate cancer (PCa) has been reported. However, there is a lack of research on cathepsins and benign prostate diseases (BPDs). This study investigated the potential genetic link between cathepsins and BPDs through the utilization of Mendelian randomization (MR) analysis to determine if a causal relationship exists., Methods: Publicly accessible summary statistics on BPDs were obtained from FinnGen Biobank. The data comprised 149,363 individuals, with 30,066 cases and 119,297 controls for BPH, and 123,057 individuals, with 3,760 cases and 119,297 controls for prostatitis. The IEU OpenGWAS provided the Genome-wide association data on ten cathepsins. To evaluate the causal relationship between BPDs and cathepsins, five distinct MR analyses were employed, with the primary method being the inverse variance weighted (IVW) approach. Additionally, sensitivity analyses were conducted to examine the horizontal pleiotropy and heterogeneity of the findings., Results: The examination of IVW MR findings showed that cathepsin O had a beneficial effect on BPH (IVW OR=0.94, 95% CI 0.89-0.98, P=0.0055), while cathepsin X posed a threat to prostatitis (IVW OR=1.08, 95% CI 1.00-1.16, P=0.047). Through reverse MR analysis, it was revealed that prostatitis had an adverse impact on cathepsin V (IVW OR=0.89, 95% CI 0.80-0.99, P=0.035), while no favorable association was observed between BPH and cathepsins. The results obtained from MR-Egger, weighted median, simple mode, and weighted mode methods were consistent with the findings of the IVW approach. Based on sensitivity analyses, heterogeneity, and horizontal pleiotropy are unlikely to distort the results., Conclusion: This study offers the initial evidence of a genetic causal link between cathepsins and BPDs. Our findings revealed that cathepsin O was beneficial in preventing BPH, whereas cathepsin X posed a potential threat to prostatitis. Additionally, prostatitis negatively affected cathepsin V level. These three cathepsins could be targets of diagnosis and treatment for BPDs, which need further research., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Cao, Liu, Gong, Wu, Wang, Zhang, Shi, Wang, Du, Zhou and Wang.)

Background: Ovotesticular disorder of sexual development (OT-DSD) is a rare sexual development disorder defined by the simultaneous existence of testicular and ovarian tissues (including follicular) in the same- or opposite-sex glands of an individual, with an incidence rate of about 1 in 100 000., Aim: This report aims to supplement the clinical presentation, pathology, diagnosis, and treatment of OT-DSD and to improve the diagnostic ability of clinicians for modified disease., Methods: This article is a retrospective analysis of a case of OT-DSD at our institution. Additionally, a comprehensive search of the PubMed database with the keywords "ovotesticular disorder of sexual development" or "true hermaphroditism" was conducted between 1956 and 2024, resulting in approximately 250 cases, and the results of the search are summarized., Results: The patient, a 44-year-old male, sought treatment at our hospital on February 6, 2023, primarily due to "intermittent hematospermia for over a month." He stated that it was discovered during infancy that his right scrotum was empty and lacking a testicle. Due to the low local medical services and the low-income family's economic conditions, he did not seek further diagnosis and treatment. After admission, the patient underwent computed tomography and magnetic resonance imaging and decided to undergo robot-assisted pelvic mass resection, which was pathologically confirmed as OT-DSD., Outcomes: The patient's definitive diagnosis was provided by postoperative pathology, and although the patient ultimately had a favorable outcome, diagnosis and treatment were delayed due to his atypical clinical presentation., Strengths and Limitations: This is a single case report; however, uncommon clinical presentations of rare diseases were identified, and a literature review was conducted. Unfortunately, there are some important missing data in the patient's medical history, including hormone assessment (testosterone, luteinizing hormone, follicle-stimulating hormone), tumor marker examination, semen analysis, scrotal ultrasound, and chromosomal analysis., Conclusion: Patients with OT-DSD have diverse types of gonads, chromosomal karyotypes, and phenotypes of external genitalia, and further exploration and research are needed for early diagnosis and treatment. In addition, cases of OT-DSD with fertility and no ambiguous genitalia are even rarer. This case guides us for adult patients with no ambiguous genitalia: if there is an inability to palpate 1 or both gonads and there is intermittent hematospermia, the possibility of OT-DSD should be suspected., Competing Interests: The authors declare no conflict of interest., (© The Author(s) 2024.

Generalized anxiety disorder (GAD) has harmful effects on physical and mental health and quality of life. Coloring therapy has been reported to have a positive effect on improving patient anxiety and depression. But there are no reported clinical trials examining their effectiveness as a treatment for GAD. This study was planned to evaluate the effectiveness of coloring therapy combined with conventional therapy in improving anxiety, depression, and positive and negative emotions with GAD. This randomized controlled study comprising 88 GAD patients was selected for intervention in different wards. The control group (n = 45) was given conventional antianxiety medication and physical therapy, and the experimental group (n = 43) received coloring therapy combined with conventional therapy. The Self-Rating Depression Scale, Self-Rating Anxiety Scale (SAS), Hamilton Depression Scale, Hamilton Anxiety Scale (HAMA), and Positive and Negative Affect Scale were assessed in both groups before and 3 weeks after the intervention. After the intervention, there were statistical differences in intra- and inter-group comparisons of anxiety, depression, and positive and negative mood scales in the experimental and control groups (p < .05). The minus in anxiety/positive emotions pre- and postintervention in the experimental group was statistically significant compared to that in anxiety/positive emotions pre- and postintervention in the control group (HAMA: d = 1.45, 95% confidence interval [CI] (0.34, 2.57), p = .011; SAS: d = 3.87, 95% CI (1.73,6.00), p = .001; positive: d = 1.76, 95% CI (0.17, 3.34), p = .030). The minus in depressive/negative emotions pre- and postintervention in the experimental group was not statistically significant compared with that in depressive/negative emotions pre- and postintervention in the control group (p > .05). For GAD patients, adding coloring therapy based on conventional drug therapy and physical therapy can not only reduce depression and negative emotions but also have better effects on reducing anxiety and improving positive emotions than conventional therapy., (© 2022 The Authors.
