PURPOSE To investigate the association of erectile dysfunction (ED), premature ejaculation (PE), and chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) in men with late-onset hypogonadism (LOH). MATERIALS AND METHODS We reviewed the data of 408 enrolled men between January 2014 and January 2019. All participants completed the Androgen Deficiency in the Aging Male (ADAM), international index of erectile function-5 (IIEF-5), National Institutes of Health chronic prostatitis symptom index (NIH-CPSI), and premature ejaculation diagnostic tool (PEDT) questionnaires. 5Azacytidine Participants were divided by ADAM positive (ADAM+ Group 1) and ADAM negative (ADAM- Group 2). RESULTS Total of 289 subjects were in Group 1 and 119 were in Group 2. The mean age was 53.8±7.8 years. The mean total testosterone was 4.8±1.2 ng/dL and showed no differences between the groups (p=0.839). In Groups 1 and 2, ED (IIEF≤21) was identified in 233 (80.6%) versus 37 (31.1%), respectively (p less then 0.001). The prevalence of PE (PEDT≥9) was 112 (38.7%) versus 13 (10.9%) in Groups 1 and 2, respectively (p less then 0.001). However, PE (intravaginal ejaculation latency time less then 5 minutes) showed no differences between the groups (p=0.863). The incidence of chronic prostatitis (NIH-CPSI pain score≥4) showed significant differences with 49 (17.0%) versus 8 (6.7%) in Groups 1 and 2, respectively (p=0.007). IIEF-5 total score showed the significantly highest negative correlation (r=-0.313, p less then 0.001). CONCLUSIONS Those who complained of LOH symptoms and positive results in the ADAM questionnaire need to be assessed concurrently with the above questionnaires. This could aid useful to detect of ED, PE, and chronic prostatitis co-occurrence.

Genome-wide association studies (GWASs) have identified ZDHHC2 as a candidate gene for schizophrenia (SCZ). We aimed to fine-map variants of ZDHHC2 conferring risk to SCZ in the Han Chinese population. METHODS Targeted sequencing of whole-exome sequences including untranslated regions (UTRs) along with neighboring regions in 1,827 schizophrenic patients and 1,004 normal controls of Han Chinese origin. RESULTS A total of 123 variants, including five common and 118 rare variants, were identified. Among common variants, rs73198534, rs530313445, and rs74406481 were significantly associated with SCZ. Nine nonsynonymous rare variants, p.Glu96fs, p.Arg127X, p.Val145Ile, p.Ala177Thr, p.Arg269Gln, p.Asn312His, p.Glu319Lys, p.Gln340X, and p.Ile347Val, identified only in patients; eight are located in the important domains, including two stop-gain variants. The 3D structural analysis and functional prediction revealed that all these eight variants may affect AMPAR expression or function, and influence the synaptic plasticity by regulating the palmitoylation of PSD95 and AKAP79/150. CONCLUSION Our results first show strong supportive evidences of the association between the ZDHHC2 and SCZ, and also provide a fine-mapping of variants of this gene in Han Chinese SCZ patients. © 2020 The Authors.

Despite high serum levels of FGF23, a decline in immunity is frequently observed in patients on hemodialysis (HD); thus, abnormalities in the FGF23-klotho signaling pathway in immune cells may occur in these patients. METHODS We analyzed the number of klotho-positive cells in peripheral blood mononuclear cells from 10 male and 6 female patients on HD and 5 healthy male subjects using flow cytometry. We analyzed the abundance of cleaved klotho protein in the murine B cell line, A20, and in the serum of HD patients and healthy subjects (HS) using flow cytometry and Western blotting. The serum level of A disintegrin and metalloprotease 17 (ADAM17) was measured in HD patients and HS using enzyme-linked immunosorbent assay. RESULTS The number of klotho-positive B cells was reduced in HD patients. Serum ADAM17 was responsible for the reduction in klotho, as a specific ADAM17 inhibitor reversed this change. The total serum levels of ADAM17 were similar in HD patients and HS; however, activated ADAM17 was increased in the serum of HD patients. CONCLUSIONS We concluded that abnormal ADAM17 activation could contribute to the immunocompromised status in patients on HD, in line with the reported role of ADAM17 as an anti-inflammatory and immunosuppressive factor. © 2020 The Authors. Immunity, Inflammation and Disease published by John Wiley & Sons Ltd.Lung cancer is one of the main causes of cancer-related death in the world, especially due to its frequency and ineffective therapeutically approaches in the late stages of the disease. Despite the recent advent of promising new targeted therapies, lung cancer diagnostic strategies still have difficulty in identifying the disease at an early stage. Therefore, the characterizations of more sensible and specific cancer biomarkers have become an important goal for clinicians. Circular RNAs (circRNAs), a type of RNA with covalently closed continuous loop structures that display high structural resistance and tissue specificity pointed toward a potential biomarker role. Current investigations have identified that circRNAs have a prominent function in the regulation of oncogenic pathways, by regulating gene expression both at transcriptional and post-transcriptional level. The aim of this review is to provide novel information regarding the implications of circRNAs in lung cancer, with an emphasis on the role in disease development and progression. Initially, we explored the potential utility of circRNAs as biomarkers, focusing on function, mechanisms, and correlation with disease progression in lung cancer. Further, we will describe the interaction between circRNAs and other non-coding species of RNA (particularly microRNA) and their biological significance in lung cancer. Describing the nature of these interactions and their therapeutic potential will provide additional insight regarding the altered molecular landscape of lung cancer and consolidate the potential clinical value of these circular transcripts.
