Background and aim

The present meta-analysis aims to investigate a potential link between pelvic inflammatory disease (PID) and an increased risk of genitourinary cancers (ovarian, cervical, uterus, and vagina cancers). While previous research has hinted at a possible link, this meta-analysis seeks to delve deeper into the available evidence. Understanding this association is crucial for preventive strategies and improving clinical management practices.

Methodology

A comprehensive literature search was conducted across various databases, covering studies published between 2016 and 2024. We included 13 observational studies meeting stringent criteria, followed by meticulous data extraction and quality assessment. Meta-analytical techniques were then employed to calculate pooled odds ratios (ORs), adjusted hazard ratios (HRs), and 95% confidence intervals (CIs), with heterogeneity assessed using the I² statistic.

Results

Our analysis revealed significant findings, underscoring the association between PID and increased risks of genitourinary cancers. Specifically, individuals with a history of PID demonstrated notably higher odds of developing ovarian cancer (OR = 1.477, 95% CI 1.033–2.207), uterine cancer (OR = 1.263, 95% CI 0.827–2.143), cervical cancer (OR = 1.000, 95% CI 0.900–1.100), and vaginal cancer (OR = 2.500, 95% CI 1.400–4.000) compared to those without such a history. The overall heterogeneity across studies was high (I² = 82.92%), suggesting varying trends across different populations and study designs.

Conclusion

This meta-analysis provides updated evidence supporting a significant association between PID and an increased risk of cervical, ovarian, and uterine cancers. Early detection and management of PID are crucial in potentially mitigating the risk of these cancers.

Background

We aimed to study the impact of first-degree family history on patients with endometrial cancer.

Methods

We conducted a retrospective chart review from January 1990 to June 2016, comparing stage I endometrial cancer patients with and without a sporadic family history of cancers. We collected the patients’ demographic information, tumor characteristics, and treatment plans. During the follow-up period, patient information on tumor recurrence and survival was collected. The chi-square test was used to assess the associations between categorical variables. The Cox proportional hazards regression model was used to estimate multivariate-adjusted hazard ratios (95% confidence interval (CI)).

Results

Among the 1737 patients with stage I endometrial cancer, 709 had a positive first-degree family history of cancers and 1028 had negative family history (FH) of cancers. Patients with positive FH were more likely to be older, have stage IB disease, and receive adjuvant radiotherapy; however, the difference was not statistically significant. At 5 years follow up, patients with a positive family history had longer time to recurrence (TTR) than their negative FH counterparts. Maternal family history of cancer was the most common, followed by a sister’s history of cancer, paternal history, brother’s history, and offspring history of cancer. Breast, endometrial, and colon cancers are the most common cancers among first-degree relatives.

Conclusion

Endometrial cancer patients with sporadic first-degree FH of cancers share similar demographics and tumor characteristics compared to their counterpart with slightly increased likelihood to be older, with stage IB disease and have a longer TTR compared to their negative counterpart.

Purpose

To assess the value of routine mid-trimester fetal ultrasound scans in detecting FCs, as well as the related ultrasound and clinical follow-up outcomes.

Methods

A retrospective analysis was conducted on 1064 fetuses who underwent standardized ultrasound screening during the mid-trimester. During the examination, high-frequency ultrasound was used to examine the fetal spine. Different frequency ultrasound probes were used to compare and analyze the detection rates of FCs. We conducted follow-up ultrasound observations on all FCs and conducted long-term follow-up observations in terms of the motor function of the children after birth.

Results

Among 1064 fetuses detected by ultrasound, a total of 910 fetuses were completely evaluated using high-frequency and low-frequency ultrasound, and 24 FCs were found. In all 24 cases of FCs, 7 cases were detected using low-frequency ultrasound, while high-frequency ultrasound detected all cases. There was a significant difference in the detection rates between the two groups (χ² = 26.323, P = 0.000). Of all the 24 FCs, 21 cysts disappeared spontaneously (87.5%); one fetus was induced for abortion due to a concurrent cleft lip; after multiple ultrasound examinations, it was found that the cyst persisted in one fetus; one case was not followed up by ultrasound. There was no statistically significant difference in the start of sitting and crawling time between the control group and the FCs group.

Conclusion

Routine mid-trimester fetal ultrasound scan detect FCs, particularly when high-frequency ultrasound probes were routinely applied. Most FCs detected by prenatal ultrasound spontaneously disappear and have no impact on the motor function of the fetus after birth (with the conus medullaris located at or above the L3 level). The shortest time interval from the detection to the disappearance of the cyst was 11 days.

Objective

To investigate the relationship between the anatomical position of the anterior arm of the mesh, measured by ultrasound through the bladder neck–mesh distance technique and the surgical outcomes after laparoscopic sacrocolpopexy (SCP) for apical prolapse.

Study design

It was a retrospective analysis of prospectively collected data in a tertiary care hospital. Between January 2019 and September 2019, 63 women who underwent laparoscopic SCP due to apical prolapse were included. Bladder neck–mesh distance was measured immediately after surgery. The pelvic floor was evaluated using the Pelvic Organ Prolapse Quantification (POP-Q) System before, 1 month, and 2.7 years (mid-term) after the surgery. Post-operative stress urinary incontinence (SUI) and Patient Global Impression of Improvement (PGI-I) scores were also assessed. The correlation between bladder neck–mesh distance and the post-operative outcomes was investigated using the Spearman rank correlation coefficient.

Results

At mid-term follow-up visit, bladder neck–mesh distance was inversely correlated with the correction of apical prolapse and post-operative SUI. No correlation was detected with the anterior compartment prolapse correction. PGI-I scores were high in all patients at mid-term follow-up, irrespective of bladder neck–mesh distance values.

Conclusion

The shorter the bladder neck–mesh distance, the better the outcome for apical compartment repair. Bladder neck–mesh distance had no correlation with the anterior anatomical correction. Shorter bladder neck–mesh distance values were positively correlated to better PGI-I scores and a higher risk of SUI.

Purpose

To construct reference charts for cervical length (CL) in pregnancy based on longitudinal measurements and to assess the value of measuring cervical length after 24 weeks of gestation.

Methods

CL was measured transvaginally in singleton pregnancies at 5 to 41 weeks. Pregnancies with more than one measurement were used for creating the CL chart, whereas any measurement after 24 weeks was considered for assessing the correlation of CL with preterm delivery.

Results

The dataset consisted of 12,601 pregnancies and 33,899 observations. Gestational age was the main predictor of CL (R² = 67.3%). Further adjustments in the fixed effects part for maternal characteristics (age, BMI, smoking status, parity, history of miscarriage, and cervical surgery) improved the prediction ability (R² = 78.4%). CL was predictive of spontaneous preterm delivery before 37 weeks when measured at any gestation between 24 and 35 weeks and it was predictive of spontaneous preterm delivery before 32 weeks when measured between 28 and 31 weeks (AUC = 0.68).

Conclusion

Gestational age is the main predictor of CL followed by maternal characteristics and history. CL assessment between 24 and 35 + 6 weeks can enhance our ability to predict spontaneous preterm delivery.

Purpose

This study aimed to assess maternal and neonatal outcomes in patients with polyhydramnios attempting trial of labor after cesarean (TOLAC) compared to those undergoing planned repeat cesarean delivery (PRCD).

Methods

A multi-center retrospective cohort study was conducted and included women with term singleton viable pregnancies following a single low-segment transverse cesarean delivery (CD) with a polyhydramnios diagnosis (maximal vertical pocket > 8 cm and/or Amniotic Fluid Index > 24 cm) within 14 days before birth who delivered between the years 2017 and 2021. Maternal and neonatal outcomes were compared between those attempting TOLAC and those opting for PRCD. The primary outcome was composite adverse maternal. Univariate analysis was followed by multivariate analysis to control for potential confounders.

Results

Out of 358 included births with a previous CD, 208 (58.1%) attempted TOLAC, while 150 had PRCD (41.9%). The successful vaginal birth after cesarean (VBAC) rate was 82.2%, and no cases of uterine rupture, hysterectomy, or maternal intensive care unit admission occurred in either group. After controlling for potential confounders, no independent association between TOLAC and composite adverse maternal (adjusted odds ratio [aOR] 0.62, 95% confidence interval [CI] 0.32–1.20, p = 0.16) and neonatal (aOR 0.89, 95% CI 0.51–1.53, p = 0.67) adverse outcomes was demonstrated.

Conclusion

In patients with a term diagnosed polyhydramnios, TOLAC appears to be a reasonable alternative associated with favorable outcomes. Larger prospective studies are needed to refine management strategies and enhance maternal and neonatal outcomes in this context.

Objective

The aim of this study was to report three cases of early severe ovarian hyperstimulation syndrome (OHSS) in patients undergoing a GnRH antagonist protocol triggered with GnRH agonist (GnRH-a), leading to hospitalization and the need for peritoneal drainage. Additionally, a review of the existing literature on this topic is provided.

Design

This is a retrospective case series and a literature review.

Setting

This study was conducted at obstetrics and gynecology department of tertiary academic referral hospitals, Israel.

Participants

This study included three patients presented with severe OHSS symptoms, including abdominal distension, ascites, and hemoconcentration.

Main outcome measures

The main focus of the treatment was to address the symptoms and prevent any further complications. The outcome was the complete recovery of the patients.

Results

The presented cases detail instances of severe OHSS following oocyte retrieval, utilizing GnRH-a for triggering. Case 1 involved a 33-year-old patient with a history of polycystic ovary syndrome (PCOS), Case 2 featured a 22-year-old patient with familial adenomatous polyposis (FAP), and Case 3 included a 41-year-old patient with a history of depressive disorder. All patients receiving supportive care, including infusions and medications, exhibited gradual improvement during hospitalization, with complete resolution observed during the 20-day post-hospitalization check-up.

Conclusions

These three cases highlight the occurrence of severe early OHSS following a GnRH antagonist protocol triggered with GnRH-a in the absence of human chorionic gonadotropin (hCG) administration for trigger or luteal-phase support. Clinicians must be aware that a GnRH-a trigger followed by a freeze-all approach does not guarantee the complete elimination of OHSS in all patients.

Purpose

To investigate sleep duration and sleep loss during antenatal period and assess associative factors, including maternal characteristic and mood symptoms.

Methods

A cohort of 3038 women was enrolled. Self-reported sleep duration and sleep loss, the latter being calculated from preferred sleep need and actual sleep duration, were measured in early, mid- and late pregnancy, and at delivery. The associations with age, BMI, parity, education, smoking, napping, and depressive and anxiety symptoms were evaluated.

Results

Sleep duration was longest in early pregnancy and shortest at delivery (7.93 h–7.76 h, p < 0.001). The proportion of short sleepers (< 6 h) increased from 1.4% to 5.9% throughout the studied period (p < 0.001). Mean sleep loss remained stable in early- and mid-pregnancy, lowering in late pregnancy (p < 0.001) and increasing again until delivery (p = 0.003). The number of women with notable sleep loss (> 2 h) was similar during the first three measurement points (9.4%, 8.9% and 9.5%), but increased until delivery (14.1%, p < 0.001). Older, multiparous, and more-depressive women slept less (p < 0.001, p < 0.001, p = 0.017). Women with higher BMI were more likely to sleep < 6 h in late pregnancy (p = 0.012). Multiparous, more-depressive, and higher-BMI women reported more sleep loss (p < 0.001, p < 0.001, p = 0.049).

Conclusion

We confirmed earlier reported decrease in sleep duration at the end of pregnancy. As a novel finding, we showed a notable increase in sleep loss during the last month of pregnancy. Various factors were associated with both short sleep and sleep loss, especially multiparity, napping and depressive symptoms.

Background

Pelvic floor stability is influenced by various biomechanical, anatomical, and physiological factors. Understanding these dynamics is crucial for improving the treatment of pelvic organ prolapse (POP) and related conditions.

Objective

To analyze the key factors affecting pelvic floor integrity and explore both non-surgical and surgical interventions to enhance stability and treatment outcomes.

Methods

This review draws from biomechanical research to assess the role of the uterosacral ligament in pelvic support, while also examining the potential of both traditional and emerging therapeutic approaches, including non-surgical interventions like vitamin C supplementation.

Results

- The uterosacral ligament demonstrates superior strength and stiffness, making it essential for structural support of pelvic organs.

- Non-surgical interventions, such as vitamin C supplementation, show potential in improving ligament integrity and preventing pelvic floor disorders.

- Emerging surgical techniques, including tendon-based procedures and injectable fibrous hydrogel composites, offer promising improvements in outcomes for patients with pelvic organ prolapse.

- Additional factors such as muscle strength and neural deficiencies contribute to the complexity of pelvic floor biomechanics, indicating the need for multifaceted treatment approaches.

Conclusion

This analysis provides a comprehensive framework for understanding and managing pelvic floor stability by integrating biomechanical, physiological, and anatomical insights. The findings highlight the potential for personalized treatment strategies to improve patient outcomes in pelvic floor disorders.
