This retrospective study aimed to analyze the treatment effect and prognostic factors of pediatric acute myeloid leukemia (AML) patients with t(8;21). A total of 268 newly diagnosed pediatric AML (pAML) enrolled from 1 January 2005 to 31 December 2022 were retrospectively reviewed, and 50 (18.7%) patients harbored t(8;21) translocation. CR rate, OS, EFS, and RFS were assessed by multivariate Logistic and Cox regression models in these patients. Of the 50 patients, 2 patients abandoned treatment during the first induction course. Of the remaining 48 patients who received double-induction therapy and were included in the final analyses, CR1 and CR2 were 75.0% (36/48) and 95.8% (46/48), respectively. The overall three-year OS, EFS, and RFS were 68.4% (95% CI, 55.0–85.1), 64.2% (95% CI, 50.7–81.4), and 65.5% (95% CI, 51.9–82.8), respectively. The presence of loss of sex chromosome (LOS) at diagnosis (n = 21) was associated with a better 3-year OS [87.5% (95% CI, 72.7–100) vs. 52.7% (95% CI, 35.1–79.3), p = 0.0089], 3-year EFS [81.6% (95% CI, 64.7–100) vs. 49.7% (95% CI, 32.4–76.4), p = 0.023], and 3-year RFS [81.6% (95% CI, 64.7–100) vs. 51.7% (95% CI, 33.9–78.9), p = 0.036] than those without LOS (n = 27), and it was also an independent good prognostic factor of OS (HR, 0.08 [95% CI, 0.01–0.48], p = 0.005), EFS (HR, 0.22 [95% CI, 0.05–0.85], p = 0.029), and RFS (HR, 0.21 [95% CI, 0.05–0.90], p = 0.035). However, extramedullary leukemia (EML) featured the independent risk factors of inferior OS (HR, 10.99 [95% CI, 2.08–58.12], p = 0.005), EFS (HR, 4.75 [95% CI, 1.10–20.61], p = 0.037), and RFS (HR, 6.55 [95% CI, 1.40–30.63], p = 0.017) in pediatric individuals with t(8;21) AML. Further analysis of combining LOS with EML indicated that the EML+LOS− subgroup had significantly inferior OS (92.9%, [95% CI, 80.3–100]), EFS (86.2%, [95% CI, 70.0–100]), and RFS (86.2%, [95% CI, 80.3–100]) compared to the other three subgroups (all p < 0.001). LOS and EML are independent prognostic factors of OS, EFS, and RFS with t(8;21) pAML patients. LOS combined with EML may help improve risk stratification. [ABSTRACT FROM AUTHOR]

Objective: With a global incidence of more than 10%, preterm birth (PTB) remains a significant concern. The vaginal microbiome strongly influences the well-being of the female reproductive tract. This study examines the correlation between changes in Lactobacillus vaginal microbiota and the PTB risk. Materials and Methods: A thorough search of PubMed, Web of Science, Cochrane Library, and EMBASE was conducted to locate studies that examined the association between changes in Lactobacillus vaginal microbiota and the risk of PTB from January 1, 2010, to January 30, 2023. The risk of PTB was determined by calculating odds ratios (ORs) with 95% confidence intervals (CIs). Results: In our analysis, there were 11 studies with 1577 pregnant women. The findings revealed a significant negative correlation between higher Lactobacillus abundance and the PTB risk (OR = 0.49, 95% CI: 0.29–0.84, p = 0.009 < 0.05). Similarly, the four individual dominant species, Lactobacillus crispatus (OR = 0.3, 95% CI: 0.14–0.67, p = 0.003 < 0.05), Lactobacillus gasseri (OR = 0.34, 95% CI: 0.17–0.69, p = 0.003 < 0.05), Lactobacillus iners (OR = 0.68, 95% CI: 0.49–0.93, p = 0.016 < 0.05), and Lactobacillus jensenii (OR = 0.43, 95% CI: 0.21–0.89, p = 0.024 < 0.05), were also negatively associated with the PTB risk. The risk of Lactobacillus for PTB was significant in both America (OR = 0.67; 95% CI: 0.50–0.92) and Asia (OR = 0.20; 95% CI: 0.09–0.47), whereas no significant risk was found in Europe (OR = 0.49; 95% CI: 0.11–2.15). Conclusions: Our study demonstrated that the abundance of Lactobacillus and the four dominant individual species (L. crispatus, L. jensenii, L. iners, and L. gasseri) were significantly and negatively associated with the PTB risk.

Haemorrhoids are a common chronic anorectal disease, and haemorrhoidectomy is the standard treatment for advanced (grade III and IV) haemorrhoids. Warm water sitz has commonly been used to stimulate urination, cleanse wounds, and decrease pain. Although urinary retention and pain usually occur within the first 24 h after surgery, the warm water sitz bath is provided 24 h after haemorrhoidectomy, which might be a missed opportunity to optimize the quality and efficiency of the care provided. To investigate the effect of early warm water sitz bath on the day of haemorrhoidectomy surgery on preventing urinary retention and reducing wound pain. This was a longitudinal double-blind study with a permuted block randomization design. This study was conducted in a surgical ward of a medical center. An average of 18 patients receiving hemorrhoid surgery in that ward every month. A total of 64 participants (32 each in the experimental and control groups) were enrolled. (The first recruitment date is January 16, 2020.) Patients who received haemorrhoidectomy for grade III or IV haemorrhoids from January to December 2020 were enrolled. The experimental and control groups received the same conventional treatment and care before the haemorrhoidectomy. The experimental group started warm-water sitz bath 6 h after the surgery, and the control group started warm water sitz bath on post-haemorrhoidectomy day 1 as usual. Urinary retention was defined as use of Foley catheter during the hospital stay or remaining urine volume ≧ 300 ml using the bladder scan. A numerical rating scale was used to rate the pain level. Each participant was evaluated 6 times in total until hospital discharge. The data were analysed by descriptive statistics, chi-square test, and independent samples t test. Generalized estimating equations and intention to treat were used to identify changes in urinary retention and pain over time and missing data, respectively. There was no significant difference in the degree of change in the number of people with urinary retention between groups. A change in the wound pain index was noted; the study group had a statistically significant lower pain score than the control group (B = − 0.81, 95 % CI: − 1.44 to − 0.18). Early warm water sitz bath was a safe and effective strategy to decrease post-haemorrhoidectomy pain, but not urinary retention. Nurses could provide early warm water sitz bath for post-haemorrhoidectomy patients' comfort. ClinicalTrials.gov ID: NCT04535765 [ABSTRACT FROM AUTHOR]
