Background: Gestational diabetes mellitus (GDM) incidence is increasing worldwide. It represents a major risk factor for adverse foetal-maternal outcomes. Awareness among women in regard to GDM-related risks (in particular foetus ones) has been proven to have an impact on compliance with recommendations. Therefore we aimed to evaluate the efficacy of our post-diagnosis counselling, that informs affected women of the GDM related risks for complications, in determining an adequate level of understanding. Method: This is a cohort study involving 400 women undergoing the 24-28 weeks 75 g oral glucose tolerance test. Two hundred women diagnosed with GDM received the post-diagnosis counselling (treatment group) and two hundred women diagnosed without did not receive any counselling (control group). Both populations were surveyed with a 5 question questionnaire regarding their awareness about GDM foetal-maternal related risks. Their level of education about GDM foetal-maternal related risks, estimated according to the number of correct answers, was scored as: primary (score 0-1), secondary (score 2-3) or tertiary (score 4-5). Results: Most of the women in the treatment group after receiving the post-diagnosis counselling have demonstrated a secondary level of education 132/200 (66%). Their mean level of awareness was higher in comparison to the control group 2.6 ± 1.8 (SD) versus 2.14 ± 1.8 (SD) p value = 0.012. In particular, they’ve demonstrated to be more aware of the risks for the foetus to become macrosomic (p = 0.004) or to die in utero (p = 0.0001). A high level of education and to have had previous pregnancies positively affected correct answers. Conclusions: Our post-diagnosis counselling has played a role in improving women awareness about GDM foetal-maternal related risks. Future study will explore the impact of women’s level of awareness on glycaemic control.

Placental protein 13 (PP13) exhibits a plasma concentration that increases gradually during normal gestation, a process that is disrupted in preeclampsia, which is characterized by elevated vascular resistance, reduced utero-placental blood flow, and intrauterine growth restriction. This study investigated PP13’s role in vascular tone regulation and its molecular mechanisms. Uterine and subcutaneous arteries, isolated from both pregnant and non-pregnant women, were precontracted with the thromboxane analogue U46619 and exposed to PP13 using pressurized myography. The molecular mechanisms were further investigated, using specific inhibitors for nitric oxide synthase (L-NAME+LNNA at 10−4 M) and guanylate cyclase (ODQ at 10−5 M). The results showed that PP13 induced vasodilation in uterine arteries, but not in subcutaneous arteries. Additionally, PP13 counteracted U46619-induced vasoconstriction, which is particularly pronounced in pregnancy. Further investigation revealed that PP13’s mechanism of action is dependent on the activation of the nitric oxide–cGMP pathway. This study provides novel insights into the vasomodulatory effects of PP13 on human uterine arteries, underscoring its potential role in regulating utero-placental blood flow. These findings suggest that PP13 may be a promising candidate for improving utero-placental blood flow in conditions such as preeclampsia. Further research and clinical studies are warranted to validate PP13’s efficacy and safety as a therapeutic agent for managing preeclampsia.

Background: Acute respiratory distress syndrome (ARDS) presents a significant challenge in critical care settings, characterized by compromised gas exchange, necessitating in the most severe cases interventions such as veno-venous extracorporeal membrane oxygenation (vv-ECMO) when conventional therapies fail. Critically ill ARDS patients on vv-ECMO may experience several complications. Limited data exist comparing complication rates between COVID-19 and non-COVID-19 ARDS patients undergoing vv-ECMO. This retrospective observational study aimed to assess and compare complications in these patient cohorts. Methods: We retrospectively analyzed the medical records of all patients receiving vv-ECMO for ARDS between March 2020 and March 2022. We recorded the baseline characteristics, the disease course and complication (barotrauma, bleeding, thrombosis) before and after ECMO cannulation, and clinical outcomes (mechanical ventilation and ECMO duration, intensive care unit, and hospital lengths of stay and mortalities). Data were compared between COVID-19 and non-COVID-19 patients. In addition, we compared survived and deceased patients. Results: Sixty-four patients were included. COVID-19 patients (n = 25) showed higher rates of pneumothorax (28% vs. 8%, p = 0.039) with subcutaneous emphysema (24% vs. 5%, p = 0.048) and longer non-invasive ventilation duration before vv-ECMO cannulation (2 [1; 4] vs. 0 [0; 1] days, p = <0.001), compared to non-COVID-19 patients (n = 39). However, complication rates and clinical outcomes post-vv-ECMO were similar between groups. Survival analysis revealed no significant differences in pre-vv-ECMO complications, but non-surviving patients had a trend toward higher complication rates and more pleural effusions post-vv-ECMO. Conclusions: COVID-19 patients on vv-ECMO exhibit higher pneumothorax rates with subcutaneous emphysema pre-cannulation; post-cannulation complications are comparable to non-COVID-19 patients.

Angular pregnancies are rare and difficult to diagnose. Evidence suggests they are associated with a higher risk of intrauterine growth restriction and abnormal third stage of labor due to a retained placenta. The lack of standardized AP diagnostic criteria impacts on their correct identification and makes the treatment of potential complications challenging. We present a case of the successful conservative surgical management of a retained placenta after a term AP also complicated by intrauterine growth restriction. Moreover, to identify the best evidence regarding AP diagnostic criteria and retained placenta therapeutic approaches, we have realized an expert literature review.

Objective. Primary non-Hodgkins lymphomas of the cervix are rare; they represent about 1 of all cases. There are no available guidelines regarding the safest mode of delivery after treatment and resolution of a cervical lymphoma. Case Report. We report the first case of a successful vaginal delivery after induction of labour in a woman recovered from a primary large B-cell lymphoma of the cervix and a literature review. Conclusion. In carefully selected patients with fully treated non-Hodgkins lymphoma of the cervix with no residual disease, induction of labour via prostaglandins pessary may be a safe option if indicated.

Purpose: Our purpose was to review the current literature regarding ophthalmologic indications for cesarean section (CS). Methods: A literature search was conducted using MEDLINE, Embase, and the Cochrane Library from inception through October 2024. The databases were searched using the following keywords: “Caesarean section” OR “Caesarean section” OR “delivery” OR “pregnancy” AND “eyes” OR “eye disorders” OR “ocular disease” OR “diabetic retinopathy” OR “myopia” OR “retinal detachment” OR “glaucoma” OR “keratoconus”. Studies were considered eligible if they described pregnancy management in women affected by an eye disorder, with insight into the mode of delivery. Results: A total of 8383 results were identified, including only 1 specific guideline and no randomized controlled trials. After a manual review, 38 manuscripts were selected for inclusion. Based on the available evidence, an elective CS may be considered on a case-by-case basis in the presence of specific ophthalmic conditions, such as high-grade myopia with subretinal neovascularization, proliferative diabetic retinopathy, advanced glaucoma, or advanced keratoconus. These conditions are rare among women of childbearing age. Conclusions: Currently, only a limited number of highly specific ophthalmic conditions may benefit from an elective CS. Considering the potential short- and long-term implications of a CS, and in line with the current World Health Organization recommendations, this surgical procedure should be reserved for cases with a clear indication. Given the paucity of data in the available literature, further prospective randomized controlled trials are necessary to enhance the quality of evidence.
