Abstract
OBJECTIVE To evaluate the relationship between the fetal head-circumference-to-maternal-height (HC/MH) ratio measured shortly before delivery and the occurrence of Cesarean section (CS) for labor dystocia. METHODS This was a multicenter prospective cohort study involving four tertiary maternity hospitals. An unselected cohort of women with a singleton fetus in cephalic presentation, at a gestational age beyond 36 + 0 weeks and without any contraindication for vaginal delivery, was enrolled between September 2020 and November 2021. The MH and fetal HC were measured on admission of the patient to the labor ward. The primary outcome of the study was the performance of the HC/MH ratio in the prediction of CS for labor dystocia. Women who underwent CS for any indication other than failed labor progression, including fetal distress, were excluded from the final analysis. RESULTS A total of 783 women were included in the study. Vaginal delivery occurred in 744 (95.0%) women and CS for labor dystocia in 39 (5.0%). CS for labor dystocia was associated with shorter MH (mean ± SD, 160.4 ± 6.6 vs 164.5 ± 6.3 cm; P < 0.001), larger fetal HC (339.6 ± 9.5 vs 330.7 ± 13.0 mm; P < 0.001) and a higher HC/MH ratio (2.12 ± 0.11 vs 2.01 ± 0.10; P < 0.001) compared with vaginal delivery. Multivariate logistic regression analysis showed that the HC/MH ratio was associated independently with CS for labor dystocia (adjusted odds ratio, 2.65 (95% CI, 1.85-3.79); P < 0.001). The HC/MH ratio had an area under the receiver-operating-characteristics curve of 0.77 and an optimal cut-off value for discriminating between vaginal delivery and CS for labor dystocia of 2.09, which was associated with a sensitivity of 0.62 (95% CI, 0.45-0.77), specificity of 0.79 (95% CI, 0.76-0.82), positive predictive value of 0.13 (95% CI, 0.09-0.19) and negative predictive value of 0.98 (95% CI, 0.96-0.99). CONCLUSIONS In a large cohort of unselected pregnancies, the HC/MH ratio performed better than did fetal HC and MH alone in identifying those cases that will undergo CS for labor dystocia, albeit with moderate predictive value. The HC/MH ratio could assist in the evaluation of women at risk for CS for labor dystocia. © 2022 The Authors.

Abstract
OBJECTIVE One of the drawbacks of fetal endoscopic tracheal occlusion (FETO) for congenital diaphragmatic hernia is the need for a second invasive intervention to re-establish airway patency. The 'Smart-TO' device is a new balloon for FETO that deflates spontaneously when placed in a strong magnetic field, therefore overcoming the need for a second procedure. The safety and efficacy of this device have not yet been demonstrated. The aim of this study was to investigate the reversibility, local side effects and occlusiveness of the Smart-TO balloon, both in a simulated in-utero environment and in the fetal lamb model. METHODS First, the reversibility of tracheal occlusion by the Smart-TO balloon was tested in a high-fidelity simulator. Following videoscopic tracheoscopic balloon insertion, the fetal mannequin was placed within a 1-L water-filled balloon to mimic the amniotic cavity. This was held by an operator in front of their abdomen, and different fetal and maternal positions were simulated to mimic the most common clinical scenarios. Following exposure to the magnetic field generated by a 1.5-T magnetic resonance (MR) machine, deflation of the Smart-TO balloon was assessed by tracheoscopy. In cases of failed deflation, the mannequin was reinserted into a water-filled balloon for additional MR exposure, up to a maximum of three times. Secondly, reversibility, occlusiveness and local effects of the Smart-TO balloon were tested in vivo in fetal lambs. Tracheal occlusion was performed in fetal lambs on gestational day 95 (term, 145 days), either using the balloon currently used in clinical practice (Goldbal2) (n = 5) or the Smart-TO balloon (n = 5). On gestational day 116, the presence of the balloon was assessed by tracheoscopy. Deflation was performed by puncture (Goldbal2) or MR exposure (Smart-TO). Six unoccluded fetal lambs served as controls. Following euthanasia, the lung-to-body-weight ratio (LBWR), lung morphometry and tracheal circumference were assessed. Local tracheal changes were measured using a hierarchical histologic scoring system. RESULTS Ex vivo, Smart-TO balloon deflation occurred after a single MR exposure in 100% of cases in a maternal standing position with the mannequin at a height of 95 cm (n = 32), 55 cm (n = 8) or 125 cm (n = 8), as well as when the maternal position was 'lying on a stretcher' (n = 8). Three out of eight (37.5%) balloons failed to deflate at first exposure when the maternal position was 'sitting in a wheelchair'. Of these, two balloons deflated after a second MR exposure, but one balloon remained inflated after a third exposure. In vivo, all Smart-TO balloons deflated successfully. The LBWR in fetal lambs with tracheal occlusion by a Smart-TO balloon was significantly higher than that in unoccluded controls, and was comparable with that in the Goldbal2 group. There were no differences in lung morphometry and tracheal circumference between the two balloon types. Tracheal histology showed minimal changes for both balloons. CONCLUSIONS In a simulated in-utero environment, the Smart-TO balloon was effectively deflated by exposure of the fetus in different positions to the magnetic field of a 1.5-T MR system. There was only one failure, which occurred when the mother was sitting in a wheelchair. In healthy fetal lambs, the Smart-TO balloon is as occlusive as the clinical standard Goldbal2 system and has only limited local side effects. © 2020 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
BACKGROUND Aim of this research is to study the situation and relationships of the adrenal gland in the first stage of development in order to give some contributes for the application of laparoscopic adrenalectomy; in the meantime we describe the series of the debate changes occurring in the constitution of the cortex and medulla. METHODS Analysis of histologic slices of thoraco-abdominal and abdominal regions of human embryos and fetuses ranging from the fifth (12 mm CR) to the twentieth week (170 mm CR). RESULTS At 12 mm CR an unique type of cells is present in the cortex; at 16 mm CR there are two different groups of cells. Sympathogonia enter into the cortex at 16 mm CR. The right adrenal gland seems enclosed into the liver and a ligament containing the middle adrenal vein reaches the vena cava inferior sulcus. The left adrenal gland, through the coelomic cavity, is in relationship with the stomach, the medial border of the spleen and the pancreatic body contained in the primitive dorsal mesogastrium. CONCLUSIONS The timing of penetration of the ganglion cells into the cortex is defined as well as the hypothesis that the matrix of the fetal and definitive cortex is the same: moreover the study of the early development allows to understand the main characteristics of both the adrenal glands which are significant for a rational and differential laparoscopic approach.

Abstract
It is known that interleukin-2 (IL-2) plays an important role in the activation of host antitumor immune response. In addition to IL-2 cell surface receptor, a soluble form of IL-2 receptor (SIL-2R) may be released in the blood and potentially be involved in the regulation of IL-2 availability. High SIL-2R levels have been found in patients with lung cancer. The current study evaluated the influence of changes in SIL-2R serum levels during the perioperative period on early relapse rate in patients with operable non-small cell lung cancer. The study included 60 patients (epidermoid carcinoma, 33; adenocarcinoma, 27). Serum levels of SIL-2R were measured with an enzyme immunoassay before surgery and 7 and 30 days after surgery. A surgery-induced increase in SIL-2R levels was seen 7 days after surgery in 38 of 60 patients. On the 30th day after surgery, SIL-2R values were lower than the preoperative values in 32 patients (Group A) or still greater in the other 28 patients (Group B). After a median follow-up of 10 months, relapse occurred in 19 of 60 patients. The relapse rate was significantly higher in Group B than in Group A patients (16 of 28 versus 3 of 32, respectively; P less than 0.001). This difference also was significant in relation to histotype and node status. This study shows that the persistence of increased SIL-2R levels in the postoperative period is associated with a higher early relapse rate in patients with operable non-small cell lung cancer. The impact of SIL-2R levels on relapse suggests that host immune defenses may influence the clinical course of patients with lung cancer. Therefore, the evaluation of SIL-2R in the perioperative period may represent a new prognostic biologic factor in operable non-small cell lung cancer.
