Breast cancer is the most common malignancy diagnosed in the female population worldwide and the leading cause of death among perimenopausal women. Screening is essential, since earlier detection in combination with improvements in breast cancer treatment can reduce the associated mortality. The aim of this study was to review and compare the recommendations from published guidelines on breast cancer screening. A total of 14 guidelines on breast cancer screening issued between 2014 and 2022 were identified. A descriptive review of relevant guidelines by the World Health Organization (WHO), the U.S. Preventive Services Task Force (USPSTF), the American Cancer Society (ACS), the National Comprehensive Cancer Network (NCCN), the American College of Obstetricians and Gynecologists (ACOG), the American Society of Breast Surgeons (ASBrS), the American College of Radiology (ACR), the Task Force on Preventive Health Care (CTFPHC), the European Commission Initiative on Breast Cancer (ECIBC), the European Society for Medical Oncology (ESMO), the Royal Australian College of General Practitioners (RACGP) and the Japanese Journal of Clinical Oncology (JJCO) for women both at average and high-risk was carried out. There is a consensus among all the reviewed guidelines that mammography is the gold standard screening modality for average-risk women. For this risk group, most of the guidelines suggest annual or biennial mammographic screening at 40–74 years, while screening should particularly focus at 50–69 years. Most of the guidelines suggest that the age limit to stop screening should be determined based on the women’s health status and life expectancy. For women at high-risk, most guidelines recommend the use of annual mammography or magnetic resonance imaging, while the starting age should be earlier than the average-risk group, depending on the risk factor. There is discrepancy among the recommendations regarding the age at onset of screening in the various high-risk categories. The development of consistent international practice protocols for the most appropriate breast cancer screening programs seems of major importance to reduce mortality rates and safely guide everyday clinical practice.

Background and Objectives: Postpartum hemorrhage (PPH) is an obstetrical emergency and although the mortality rate from PPH has decreased, it is still considered a challenge in obstetrics. This study aimed to estimate the rate of primary PPH, as well as to investigate the potential risk factors and management options. Material and methods: This was a retrospective case-control study of all cases with PPH (blood loss > 500 mL, irrespective of the mode of delivery) managed in the Third Department of Obstetrics and Gynecology, Aristotle University of Thessaloniki, Greece, from 2015 to 2021. The ratio of cases to controls was estimated to be 1:1. The chi-squared test was used to examine if there was any relationship between several variables and PPH, while subgroup multivariate logistic regression analyses of certain causes of PPH were also conducted. Results: During the study period, from a total of 8545 births, 219 (2.5%) pregnancies were complicated with PPH. A maternal age > 35 years (OR: 2.172; 95% CI: 1.206–3.912; p = 0.010), preterm delivery (<37 weeks) (OR: 5.090; 95% CI: 2.869–9.030; p < 0.001) and parity (OR: 1.701; 95% CI: 1.164–2.487; p = 0.006) were identified as risk factors for PPH. Uterine atony was the main cause of PPH in 54.8% of the women, followed by placental retention in 30.5% of the sample. Regarding management, 57.9% (n = 127) of the women received uterotonic medication, while in 7.3% (n = 16), a cesarean hysterectomy was performed to control PPH. Preterm delivery (OR: 2.162; 95% CI: 1.138–4.106; p = 0.019) and delivery via a cesarean section (OR: 4.279; 95% CI: 1.921–9.531; p < 0.001) were associated with a higher need for multiple treatment modalities. Prematurity (OR: 8.695; 95% CI: 2.324–32.527; p = 0.001) was identified as an independent predictor for an obstetric hysterectomy. From the retrospective analysis of the births complicated by PPH, no maternal death was identified. Conclusions: Most of the cases complicated with PPH were managed with uterotonic medication. An advanced maternal age, prematurity and multiparity had a significant impact on the occurrence of PPH. More research is needed on the risk factors of PPH, while the establishment of validated predictive models would be of value.

Cervical cancer remains one of the main causes of female mortality, especially in middle- and low-income countries, despite efforts towards the implementation of global vaccination against human papillomavirus (HPV). The aim of this study was to review and compare the most recently published international guidelines providing recommendations on cervical cancer screening strategies among average and high-risk women. Thus, a comparative review of guidelines by the US Preventive Services Task Force (USPSTF), the American Cancer Society (ACS), the American Society of Clinical Oncology (ASCO), the World Health Organization (WHO), the Canadian Task Force on Preventive Health Care (CTFPHC), the Cancer Council Australia (CCA), and the European Guidelines (EG) was conducted. There is an overall agreement regarding the suggestions made for women younger than 21 and those older than 65, with all guidelines stating against routine screening, with the exceptions of CTFPHC and CCA that expand the age group to up to 70 and 75 years, respectively. Continuation of screening in older women is also suggested in those with a history of a precancerous lesion and those with inadequate screening. Most guidelines recommend routine screening at 30–65 years, while the WHO advises that screening should be prioritized at 30–49 years. HPV DNA testing is the method of choice recommended by most guidelines, followed by cytology as an alternative, except for CTFPHC, which refers to cytology only, with self-sampling being an acceptable method by most medical societies. Agreements exist regarding recommendations for specific groups, such as women with a history of total hysterectomy for benign reasons, women with a complete vaccination against HPV, individuals from the lesbian, gay, bisexual, transgender, and queer communities and women with multiple sexual partners or early initiation of sexual activity. On the other hand, the age group of 21–29 is addressed differently by the reviewed guidelines, while differentiations also occur in the screening strategies in cases of abnormal screening results, in women with immunodeficiency, those with in utero exposure to diethylstilbestrole and pregnant women. The development of consistent practice protocols for the most appropriate cervical cancer screening programs seems to be of major importance to reduce mortality rates and safely guide everyday clinical practice.

Introduction: We aimed to describe and review the epidemiological aspect of the disease pattern of a series of perimenopausal and postmenopausal women with a histology confirmation of endometriosis. Material and Methods: We retrospectively examined the clinical records of 184 perimenopausal and 46 postmenopausal women with endometriosis. Data were collected and analyzed from 1100 patients’ charts with confirmed endometriosis and involved cases from two different geographical areas, New Haven (US) and Greece. The statistical methods included ×2 and the Mann-Whitney U test. In the perimenopausal group (age 45–54 years), there were 184 patients (16.7%) and the postmenopausal group (55–80 years) had 46 (4.2%). The average age of diagnosis was (49 ± 2.3) and (61.2 ± 5.1), respectively (p < 0.01). Results: Advanced endometriosis was more aggressive in the perimenopausal group (p < 0.05); in the same group, we observed a higher left-sided predisposition of endometriosis in comparison with the right side (p < 0.01). Endometrioma was the most common gynecological condition among patients with perimenopausal endometriosis in relation to the postmenopausal group (p < 0.001). Additionally, we found uterine leiomyomata more prominent in the perimenopausal group (p < 0.05). In contrast, adenomyosis was found higher in postmenopausal patients (p < 0.05); further, 24 cases with dry eye we observed. Conclusions: Postmenopausal endometriosis is an important underestimated condition. Although the reported situation is not common, various clinicopathological characteristics were observed in both groups. Clinicians should be aware that there is a correlation between endometriosis and endometriosis-associated ovarian cancer in perimenopausal and postmenopausal age.

Sophisticated screening protocols for genetic abnormalities constitute an important component of current prenatal care, aiming to identify high-risk pregnancies and offer appropriate counseling to parents regarding their options. Definite prenatal diagnosis is only possible by invasive prenatal diagnostic testing (IPDT), mainly including amniocentesis and chorionic villous sampling (CVS). The aim of this comparative review was to summarize and compare the existing recommendations on IPDT from the most influential guidelines. All the reviewed guidelines highlight that IPDT is indicated based on a positive screening test rather than maternal age alone. Other indications arise from medical history and sonography, with significant variations identified between the guidelines. The earlier time for amniocentesis is unequivocally set at ≥15 gestational weeks, whereas for CVS, the earlier limit varies from ≥10 to ≥11 weeks. Certain technical aspects and the overall approach demonstrate significant differences. Periprocedural management regarding Rhesus alloimmunization, virologic status and use of anesthesia or antibiotics are either inconsistent or insufficiently addressed. The synthesis of an evidence-based algorithm for IPDT is of crucial importance to healthcare professionals implicated in prenatal care to avoid unnecessary interventions without compromising optimal prenatal care.
