Association of CD133, ALDH1, CD117 and OCT4 expression with prognosis of patients with cervical cancer.

Cancer stem cells (CSC), a small population of neoplastic cells, are associated with worse prognosis. The aim of this study was to evaluate the expression of ALDH1, CD117, CD133 and OCT4; potential markers of CSC; and their associations with the prognosis of women diagnosed with cervical cancer. This retrospective cohort study included 126 women diagnosed with cervical cancer whose biopsies were analyzed by immunohistochemistry. Median values of marked cells were used to define cutoff points for low and high expression. For specific survival, multivariate analyses showed statistical significance for lymph node metastases (HR 8.15; 95% CI 3.00-22.18) and borderline significance for high CD133 expression (p = 0.058). For overall survival, multivariate analyses showed statistical significance for IIA-IVB staging (HR 4.60; 95% CI 1.46-14.56), lymph node metastases (HR 5.13; 95% CI 12.02-13.03) and high CD133 expression (2.67; 95% CI 1.11-6.43). Considering only women with SCC, the same clinicopathological variables were associated with worse specific and overall survival in univariate analyses. However, higher expression of CD 133 (HR 11.10; 95% CI 2.42-50.94 and 6.00; 95% CI 2.02-17.87) and staging IIA-IVB (HR 5.96; 95% CI 1.30-27.34 and HR 12.47; 95% CI 2.45-63.54) respectively impacted negatively specific and overall survival, as multivariate analyses showed. Secondarily, it was observed that ALDH1 expression was associated with adenocarcinoma and CD117 expression with squamous cells carcinoma. Higher expression of CD133 was associated with worse specific and overall survival, indicating that it could have relevance as a clinical marker and therapeutic target.

Comparison of the effect of noninvasive radiofrequency with vaginal estrogen and vaginal moisturizer in the treatment of vulvovaginal atrophy in postmenopausal women: a randomized clinical trial.

OBJECTIVE: To compare the effect of noninvasive radiofrequency (RF) with vaginal estrogen (E), and vaginal moisturizer (M) on improving vulvovaginal atrophy (VVA) in women with genitourinary syndrome of menopause. METHODS: A total of 32 postmenopausal women who met the inclusion criteria were randomized into three intervention arms to receive one of the following treatments: three sessions of noninvasive RF therapy (RF arm); intravaginal estriol cream 1 mg applied daily for 2 weeks, followed by 1 mg applied two times weekly or 1 mg of estradiol vaginal fast-dissolving film applied daily for 2 weeks, followed by 1 mg applied two times weekly (E arm); and intravaginal moisturizer two times a week (M arm). Assessments at baseline and after 4 months were conducted using Vaginal Health Index score, Vaginal Maturation, visual analog scale for VVA symptoms (dyspareunia, dryness, and burning), and Menopause Rating Scale (MRS) for urogenital symptoms. Vaginal wall biopsies were administered to participants who consented, pretreatment and posttreatment (at baseline and after 4 months of follow-up). RESULTS: After 4 months, the Vaginal Health Index showed an increase of 6.6 points in mean total score in the RF arm, also in the E arm (+7.3 points), with no significant improvement in the M arm (+1.5 points) (interaction effect: RF, E ≠ M, P < 0.001). Regarding vaginal maturation, there was a significant increase in superficial cells in the E arm (+31.3), with no significant changes in the RF (+9.3) and M (-0.5) arms (interaction effect: E ≠ M, P < 0.001). Vaginal pH decreased significantly in the E arm (-1.25), with a similar response in the RF arm (-1.7), with no significant improvement in the M arm (-0.25) (interaction effect: RF, E ≠ M, P < 0.001).There was a significant improvement in the MRS score for VVA symptoms in the three intervention arms, with no predominance of any arm, whereas the improvement in the total MRS score for urogenital symptoms showed a predominance of the RF arm (ΔRF: -7.8; ΔE: -3.5; ΔM: -2.3; RF ≠ E, M). According to histopathologic analysis, there was no statistically significant increase in glycogenation ( P = 0.691) or epithelial cone height ( P = 0.935), despite an increase in the median delta (difference between pretreatment and posttreatment) in the three intervention arms (glycogenation: RF arm Δ = +118.4%; E arm Δ = +130.9%; M arm Δ = +24.9%; epithelial cone height: RF arm Δ = +33.5%; E arm Δ = +18.6%; M arm Δ = +22.3%). CONCLUSION: The effect of noninvasive RF on the treatment of vulvovaginal symptoms of genitourinary syndrome of menopause was similar to vaginal estrogen, except for hormonal cytology, and superior to vaginal moisturizer, with improvement in some histomorphometric parameters. These findings are promising, especially for the population that cannot or prefers not to use vaginal estrogen therapy.

Analysing the context and characteristics of legal abortion and comprehensive post-abortion care among adolescents aged 10-14 in a network of sentinel centres in Latin America: a retrospective cross-sectional study, 2016-2020.

Pregnancy-related complications are a substantial source of morbidity and mortality among adolescents in low- and middle-income countries. While the youngest adolescents (those aged 10-14) are considered to be at particularly high risk of adverse outcomes, there is little empirical data available on their sexual and reproductive health. Using a unique dataset of clinical records drawn from a regional network of sentinel centres providing legal abortion and comprehensive post-abortion care in 12 Latin American and Caribbean countries, we described the population of adolescents aged 10-14 seeking legal abortion and post-abortion care and calculated institutional rates of complications, using older adolescents (aged 15-19) and young adults (aged 20-24) as comparator groups. We also assessed the quality of care provided as compared to WHO recommendations. Nearly 17% (89 out of 533) of young adolescents sought care when they were already at 15 or more weeks' gestation. Young adolescents were at higher risk of pre-procedure and intra-operative complications than older adolescents and young adults, though the trend is less clear for the most severe complications. In general, the quality of care provided by centres in the network was aligned with WHO recommendations for safe abortion and comprehensive post-abortion care. Taken together, these findings provide insight into the challenges facing the global health community in assuring the sexual and reproductive health and rights of the youngest adolescents, and outline avenues for future research, advocacy, and evidence-based policymaking.

Long-term outcomes of concomitant cisplatin plus radiotherapy versus radiotherapy alone in patients with stage IIIB squamous cervical cancer: A randomized controlled trial.

OBJECTIVE: The present analysis determined the disease free survival (DFS) and overall survival (OS) at up to 14 years of follow-up in women who participated in our previous phase 3 randomized controlled clinical trial, in which women with stage IIIB squamous cervical cancer received either cisplatin plus RT or RT alone for treatment. The first study showed that the addition of cisplatin to RT offered a significant benefit in DFS, but not in OS. METHODS: The present analysis examined DFS and OS in 146 women from the original cohort (72 patients in the CRT arm and 74 patients in the RT-only arm) with follow-up of up to 14 years. RESULTS: Longer term follow-up showed that treatment with CRT offers a significant benefit in DFS and OS compared with treatment with RT only. Patients who received RT alone had significantly worse OS (HR, 1.88; 95% CI, 1.09-3.24) and DFS (HR, 1.82; 95% CI, 1.07-3.08) compared with patients who received CRT. The multivariate analyses also showed that the patients with baseline Karnofsky performance status (KPS) <90% showed significantly worse OS (HR, 3.11; 95% CI, 1.78-5.43), as did those with hemoglobin <10 mg/dL (HR, 4.32; 95% CI, 2.23-8.36). Patients with baseline KPS < 90% showed significantly worse DFS (HR, 2.83; 95% CI, 1.60-5.01), as did those with hemoglobin <10 mg/dL (HR, 4.16; 95% CI, 2.17-7.95). CONCLUSIONS: For stage IIIB cervical cancer, treatment with CRT offers a significant benefit in DFS and OS compared with treatment with RT only.

How do urogynecology and pelvic floor dysfunction terms used in female pelvic medicine and reconstructive surgery research relate to social media indicators?

INTRODUCTION AND HYPOTHESIS: The association between social media (SoMe) indicators and citation metrics is still controversial. we aimed to evaluate the frequency of urogynecology-related terms ("urogynecology" [UG] and "pelvic floor/dysfunction" [PF/PFD]) mentioned by traditional databases (Web of Science [WOS]) and journal ranking indicators (SCImago), as well as their association with SoMe (Altmetric database). METHODS: In April 2019, two authors performed a search that was divided into three steps. The first one was to assess journals within the WOS Obstetrics/Gynecology and Urology categories updated to 2017 using UG and PF/PFD. The second step was to rank these studies in SCImago by the highest numbers of WOS and to correlate with journal h-index and SJR. The third step was to analyze SoMe indicators such as the Altmetric Attention Score (AAS) for each study and journal retrieved. RESULTS: The International Urogynecology Journal (IUJ) and Neurourology and Urodynamics (NAU) were the first (n = 1,394) and second (n = 974) most highly cited journals when using UG and PFD. IUJ also presented manuscripts with the highest AAS for UG and PF/PFD. Social media represented 74-93% of AAS calculated among the 20 top cited studies. For UG, SoMe presented 8,050 mentions, led by Twitter (n = 7,326). The same distribution was seen for PFD (8,493 mentions for SoMe, Twitter with 7,653). The higher the WOS citation, the higher the AAS (r = 0.483; p = 0.03). CONCLUSION: UG and PF/PFD terms are highly cited in databases and IUJ was the journal most frequently connected with them. Among SoMe tools, Twitter was the most frequently cited. WOS citations correlated with AAS.

Waist-to-height ratio percentiles and cutoffs for obesity: a cross-sectional study in brazilian adolescents.

This study aimed to describe the distribution of waist-to-height ratio (WHtR) percentiles and cutoffs for obesity in Brazilian adolescents. A cross-sectional study including adolescents aged 10 to 15 years was conducted in the city of São Paulo, Brazil; anthropometric measurements (weight, height, and waist-circumference) were taken, and WHtRs were calculated and then divided into percentiles derived by using Least Median of Squares (LMS) regression. The receiver operating characteristic (ROC) curve was used in determining cutoffs for obesity (BMI ≥ 97th percentile) and Mann-Whitney and Kruskal-Wallis tests were used for comparing variables. The study included 8,019 adolescents from 43 schools, of whom 54.5% were female, and 74.8% attended public schools. Boys had higher mean WHtR than girls (0.45 ± 0.06 vs 0.44 ± 0.05; p=0.002) and higher WHtR at the 95th percentile (0.56 vs 0.54; p<0.05). The WHtR cutoffs according to the WHO criteria ranged from 0.467 to 0.506 and 0.463 to 0.496 among girls and boys respectively, with high sensitivity (82.8-95%) and specificity (84-95.5%). The WHtR was significantly associated with body adiposity measured by BMI. Its age-specific percentiles and cutoffs may be used as additional surrogate markers of central obesity and its co-morbidities.
