Purpose: Twenty five years have passed since the first national survey on erectile dysfunction (ED) in Japan. The Japanese Society for Sexual Medicine conducted a nationwide survey on the actual status of sexual function targeting men over 20 years old in Japan using validated questionnaires commonly used in clinical practice. Materials and Methods: Japanese men aged 20 to 79 years participated in our online epidemiological study on sexual dysfunction. Erectile status was assessed by direct questioning and specific questionnaires. Risk factors and frequencies of sexual intercourse, masturbation, nocturnal erections, and feeling sexual desire were assessed. The prevalence of these risk factors was compared between men with and without ED. Prevalence and frequencies were calculated for each 5-year age group. Main outcomes were the prevalence and number of patients with ED and simultaneous evaluation of age-related variations. Results: Direct questioning of the men revealed that 13.0% felt troubled by ED. Although 81.0% of them had at least some ED symptoms based on a Sexual Health Inventory For Men score of ≤21, the prevalence of men with ED by Erection Hardness Score (EHS), the most appropriate questionnaire for Japanese with low sexual activity, was 30.9%, indicating that 14,012,596 men have ED. Most risk factors were related with ED, whereas frequencies of sexual intercourse, masturbation, nocturnal erections, and feeling sexual desire were affected by aging. However, the low frequency of these factors in the young generation was surprising. Conclusions The EHS-based assessment revealed a prevalence of ED of 30.9%, which affected approximately 14 million men, and that the sexual desire, erection stiffness, orgasms, and satisfaction were lower than expected in young Japanese men, especially those aged 20 to 24 years, although those factors tended to worsen with aging. We believe that these findings actually reveal the current sexual status of men in Japan.

Objective: To investigate the effectiveness and safety of continuous infusion of midazolam for the treatment of headache and/or nausea/vomiting in patients with brain tumors or cancer-associated meningitis. Methods: Patients who presented with headache and/or nausea/vomiting and underwent continuous infusion of midazolam from April 2005 to March 2021 were retrospectively analyzed. Results: Among 22 patients, 19 presented with headache and 14 with nausea/vomiting. The success rate of continuous infusion of midazolam for headache was 89% and that for nausea/vomiting was 78%. The mean number of vomiting episodes within 24 hours from the start of midazolam administration was 0.14±0.36, which was significantly lower than that from 24 hours before to the start of administration (1.43±1.60, P=0.015). Sedation was observed as an adverse event in five (23%) patients, but no patients developed respiratory depression. Conclusion: When conventional therapies are ineffective for headache and/or nausea/vomiting caused by brain tumors or cancer-associated meningitis, continuous infusion of midazolam may improve symptoms and should be considered as a treatment option.

Methods: Participants included 376 patients who received denosumab (60 mg every 6 months) from January 2013 to June 2021. The time from therapy initiation to discontinuation was used to measure persistence, and that between initial and subsequent injections was used to determine adherence. The pandemic period was from March 2020 to December 2021. Results: Patients were divided into those treated after March 2020 (pandemic group, n=244) and those who discontinued treatment before March 2020 (non-pandemic group, n=132). Non-persistent cases accounted for 154, including 24 (20%), 64 (19%), and 66 (53%) aged ≤59 years, 60–79 years, and ≥80 years, respectively. The overall persistence rate at 78 months was 59.2%. Postponed cases were significantly lower in the non-pandemic group than in the pandemic group (8% vs. 15%, p =0.042). Postponement with a delay of 1–2 months did not significantly differ between the two groups, but with a significant difference for a delay of ≥3 months (0% vs. 36%, p =0.024). Conclusions Denosumab adherence remained constant but postponed cases significantly increased during the COVID-19 pandemic. Better communication by health providers on denosumab adherence and alternative administration may reduce dosing interruptions in similar pandemic situations.

Artesunate possesses the potential of intervening with glioma, however, its pharmacological mechanisms remain unclarified. Firstly, the effects of artesunate on cell activity, proliferation and apoptosis of U87 and U251 human glioma cells were explored. It was found that artesunate exerted stronger inhibitory effects on the activity and proliferation of U87 cells than U251 cells. It could significantly promote apoptosis in U87 cells (P < 0.05), while only high dose of artesunate can promote that of U251 cells (P < 0.01), detected by Hoechst and TUNEL cell apoptosis staining. Further, the differential expression gene sets between artesunate-sensitive and non-sensitive cell line, as well the therapeutic effects-related genes of artesunate were obtained through transcriptome sequencing and differential data analysis by using the lysates of U87 and U251 cells before and after artesunate treatment, aiming to explore the molecular mechanism of distinct artesunate sensitivity to two types of cells. Then, key putative targets that related to therapeutic effects were screened by constructing the interaction network of differential genes of three above comparison groups, and calculating their topological characteristics. Pathway enrichment analysis showed that those key putative targets were significantly enriched in several signaling pathways that were closely associated with the main pathological changes of glioma, among which apoptosis-related activating transcription factor 4 (ATF4)-DNA damage induced transcript 3 (DDIT3)- polyadenosine diphosphate ribose polymerase 1 (PARP1) signaling axis was the most enriched in. Molecular docking indicated that artesunate had fine binding affinities with ATF4 and DDIT3. Above all, this study preliminarily revealed that ATF4-DDIT3-PARP1 signaling axis is the target pathway of artesunate intervening with U87 glioma cells, and PARP1 may be an important gene for U251 cells to develop resistance to artesunate. Our results not only provide fundamental experimental evidence for artesunate as a potential therapeutic drug in glioma treatment, but shed light into overcoming drug resistance in its clinical therapy.

Objective: This study aimed to investigate the feasibility of a patient registry system for assessing PCT (palliative care team) by PRO (Patient-reported outcome) in Japan. Methods: We operated a patient registry system with electronic data collection at eight hospitals in 2021 in Japan. We consecutively included newly referred patients for a month and followed up with them for a month. IPOS or ESAS obtained as PRO at the start of the intervention, three days later, and every week after. The primary endpoint was the response rate to the symptom rating scale by patients and providers. Results: 318 patients were enrolled. The patient response rate was 59.1% at intervention and 37.0% after intervention, and the medical provider response rate was 98.4% at intervention and 70.3% after intervention. Interviews with PCT members indicated that participants required support to input PRO responses required support and paper questionnaire was better and that managing the survey date and overall management was burdensome. Discussion: Although only about half of the patients were able to respond to the PRO, this was the same level as in previous studies. The system and its operation method have many problems. We found that improvements such as reducing items and making the patient interviews paper-based are necessary to expand the system nationwide.
