Objective: Recurrent pregnancy loss (RPL) is a fertility problem for which no exact mechanism of abortion or efficient treatment has been described. This study was conducted between 2018 and 2019 to investigate the effectiveness of autologous platelet-rich plasma (PRP) in improving the live birth rate of women with RPL who required in vitro fertilization (IVF). Methods: A total of 63 patients with at least two previous pregnancy losses and no specific cause detected for the RPL were included and randomly assigned into two groups (PRP and control). Intrauterine infusion of 0.5 mL of autologous PRP was performed 48 hours before embryo transfer in the PRP group. Women in the control group received standard treatment. Results: Forty patients completed the study. The baseline and cycle characteristics of the participants did not differ significantly between the PRP and control groups. The clinical pregnancy rate was higher in the PRP group (35% vs. 20%, P=0.288). The live birth rate was 15% in the PRP group, but no live births were recorded in the control group (P=0.231). Conclusion This is the first study to show that intrauterine infusion of PRP in patients with RPL who undergo IVF may increase the chance of live birth.

Objectives: No comprehensive analysis has yet been published regarding global trends in childhood sexual abuse (CSA) and bullying victimization (BV). The present study offers a longitudinal perspective on their prevalence worldwide. Methods: CSA and BV rates were extracted from the Global Burden of Disease study, spanning the years 1990 to 2019 across 204 countries. Trends by gender, region, and human development index (HDI) were examined. Results: For both boys and girls, and in both high-HDI and low-HDI countries, CSA rates did not significantly change from 1990 to 2019 (p>0.05). However, BV rates increased significantly in high-HDI and low-HDI countries for both genders (p<0.001). Subsequently, we analyzed trends separately by gender across all countries, without considering development level. In this analysis, CSA rates among girls decreased from 1990 to 2000, followed by an increasing tendency after 2000; overall, an upward trend was evident between 1990 and 2019 (p=0.029). In contrast, no significant pattern was observed for boys. Notably, BV demonstrated an increasing trend across all regions when HDI was not considered (p<0.05), with African populations experiencing the most pronounced rise (p<0.001). Globally, boys consistently exhibited higher BV rates than girls. Conclusions Our research indicates that, on a global scale, rates of CSA among girls have been rising. Additionally, BV rates have increased in all regions for both boys and girls. Notably, this trend in BV rates is occurring irrespective of HDI. These findings underscore the necessity for targeted interventions in areas with high rates of CSA and BV.

BACKGROUND: The dietary habits and lifestyle changes during the COVID-19 pandemic could affect the urinary risk factors in kidney stone formers. In this study, we investigated the effects of the COVID-19 pandemic on 24-h urine metabolites, as a surrogate for dietary intake, in patients with kidney stones, in Tehran, Iran. METHODS: We evaluated the medical records of all patients with urolithiasis who visited in our stone prevention clinic from the beginning of COVID-19 in Iran to 1 year later (Feb 2020-Feb 2021) and compared it with the patients' medical records in the same period a year before COVID-19 (Feb 2019-Feb 2020). RESULTS: The results of our stone prevention clinic showed a decrease in the number of visits during COVID-19. Twenty-four-hour urine urea, sodium, and potassium were significantly lower, and 24-h urine magnesium was significantly higher during COVID-19. Higher 24-h urine oxalate was only shown in patients with the first-time visit, whereas lower 24-h urine uric acid and citrate were only shown in patients with the follow-up visits. CONCLUSIONS COVID-19 pandemics may change some of the dietary habits of the patients, including lower salt, protein, and fruit and vegetable intake. Although economic issues, restricted access, or sanitation issues may be the reason for the undesirable dietary changes, the importance of a quality diet should be discussed with all patients, as possible. Since the number of patients visited in the stone clinic was lower during COVID-19, virtual visits could be an excellent alternative to motivate patients with kidney stones.
