RESUMEN

Birth prior to 37 completed weeks of gestation is referred to as preterm (PT). Premature newborns are at increased risk of developing infections as neonatal immunity is a developing structure. Monocytes, which are key players after birth, activate inflammasomes. Investigations into the identification of innate immune profiles in premature compared to full-term infants are limited. Our research includes the investigation of monocytes and NK cells, gene expression, and plasma cytokine levels to investigate any potential differences among a cohort of 68 healthy PT and full-term infants. According to high-dimensional flow cytometry, PT infants have higher proportions of CD56+/- CD16+ NK cells and immature monocytes, and lower proportions of classical monocytes. Gene expression revealed lower proportions of inflammasome activation after in vitro monocyte stimulation and the quantification of plasma cytokine levels expressed higher concentrations of alarmin S100A8. Our findings suggest that PT newborns have altered innate immunity and monocyte functional impairment, and pro-inflammatory plasmatic profile. This may explain PT infants' increased susceptibility to infectious disease and should pave the way for novel therapeutic strategies and clinical interventions.

RESUMEN

OBJECTIVES: To report the outcome of fetuses with a prenatal diagnosis of congenital lung malformation (CLM) diagnosed on ultrasound by performing a comprehensive assessment of these outcomes through a systematic review and meta-analysis. CONTENT: CLMs are a heterogeneous group of anomalies that involve the lung parenchyma and its bronchovascular structures. Their presentation and evolution are variable, from entirely asymptomatic lesions with sonographic regression in utero to hydropic fetuses requiring fetal therapy, intrauterine death or neonatal morbidity. A systematic review was conducted in Medline, Embase and Cochrane databases including studies on fetuses with CLM diagnosed prenatally in order to report the in-utero natural history of these lesions. Thirty-nine studies (2,638 fetuses) were included in the final review. SUMMARY: Regression/reduction in size of the lung lesion during pregnancy was reported in 31 % of cases, while its increase in 8.5 % of cases. Intra-uterine death complicated 1.5 % of pregnancies with fetal CLM, while neonatal and perinatal death were 2.2 and 3 %, respectively. Neonatal morbidity occurred in 20.6 % of newborns with CLM; 46 % had surgery, mainly elective. In fetuses with CLM and hydrops, fetal/perinatal loss occurred in 42 %. Assessment of the role of fetal therapy in improving the outcomes of pregnancies complicated by CLM was hampered by the small number of included cases and heterogeneity of type of interventions. OUTLOOK: Fetuses with CLM prenatally diagnosed have a generally favorable outcome. Conversely, there is a low quality of evidence on the actual role of fetal therapy in improving the outcome of fetuses presenting with these anomalies.

RESUMEN

Facioscapulohumeral muscular dystrophy (FSHD) has been associated with the deletion of an integral number of 3.3 kb units of the polymorphic D4Z4 repeat array at 4q35. The prenatal identification of this defect can be carried out on chorionic villi or amniocytes, whereas preimplantation genetic testing for monogenic disorders (PGT-M) requires molecular markers linked to the D4Z4 allele of reduced size. In this context the reliability of this association is crucial. To test the informativeness of the nearby polymorphic markers we investigated recombination at 4q35 using the polymorphic markers D4S1523, D4S163 and D4S139 positioned at 0.55, 0.5 and 0.21 Mb proximal to the D4Z4 array respectively. We determined the probability of recombination events to occur in the D4Z4-D4S1523 interval considering 86 subjects belonging to 12 FSHD families and found a recombination frequency of 14% between D4Z4 and D4S1523. Our study also revealed the occurrence of de novo variants and germline mosaicism. These findings highlight the recombinogenic nature of the 4q subtelomere and indicate that caution should be taken when interpreting PGT-M results. It is advisable that a woman who underwent a PGT-M cycle undertakes a prenatal DNA analysis to confirm the size of the D4Z4 alleles carried by the fetus.

RESUMEN

Neuromuscular junctions (NMJs) are specialized synapses, crucial for the communication between spinal motor neurons (MNs) and skeletal muscle. NMJs become vulnerable in degenerative diseases, such as muscle atrophy, where the crosstalk between the different cell populations fails, and the regenerative ability of the entire tissue is hampered. How skeletal muscle sends retrograde signals to MNs through NMJs represents an intriguing field of research, and the role of oxidative stress and its sources remain poorly understood. Recent works demonstrate the myofiber regeneration potential of stem cells, including amniotic fluid stem cells (AFSC), and secreted extracellular vesicles (EVs) as cell-free therapy. To study NMJ perturbations during muscle atrophy, we generated an MN/myotube co-culture system through XonaTM microfluidic devices, and muscle atrophy was induced in vitro by Dexamethasone (Dexa). After atrophy induction, we treated muscle and MN compartments with AFSC-derived EVs (AFSC-EVs) to investigate their regenerative and anti-oxidative potential in counteracting NMJ alterations. We found that the presence of EVs reduced morphological and functional in vitro defects induced by Dexa. Interestingly, oxidative stress, occurring in atrophic myotubes and thus involving neurites as well, was prevented by EV treatment. Here, we provided and validated a fluidically isolated system represented by microfluidic devices for studying human MN and myotube interactions in healthy and Dexa-induced atrophic conditions-allowing the isolation of subcellular compartments for region-specific analyses-and demonstrated the efficacy of AFSC-EVs in counteracting NMJ perturbations.

RESUMEN

Congenital disorders of glycosylation (CDG) are an expanding group of metabolic disorders that result from abnormal protein glycosylation. A special subgroup of CDG type II comprises defects in the Conserved Oligomeric Golgi Complex (COG). In order to further delineate the genotypic and phenotypic spectrum of COG complex defect, we describe a novel variant of COG6 gene found in homozygosity in a Moroccan patient with severe presentation of COG6-CDG (OMIM #614576). We compared the phenotype of our patient with other previously reported COG6-CDG cases. Common features in COG6-CDG are facial dysmorphism, growth retardation, microcephaly, developmental disability, liver or gastrointestinal disease, recurrent infections, hypohidrosis/hyperthermia. In addition to these phenotypic features, our patient exhibited a disorder of sexual differentiation, which has rarely been reported in COG6-CDG. We hypothesize that the severe COG6 gene mutation interferes with glycosylation of a disintegrin and metalloprotease family members, inhibiting the correct gonadal distal tip cells migration, fundamental for the genitalia morphogenesis. This report broadens the genetic and phenotypic spectrum of COG6-CDG and provides further supportive evidence that COG6-CDG can present as a disorder of sexual differentiation.

RESUMEN

INTRODUCTION: Corpus callosum agenesis (ACC) is frequently diagnosed during fetal life; its prognosis depends also on additional anomalies. The additional value of fetal magnetic resonance imaging (MRI) in fetuses with "isolated" complete (cACC) and partial (pACC) agenesis of the corpus callosum on ultrasound is still debated. MATERIAL AND METHODS: We performed a systematic literature review and meta-analysis including fetuses with a prenatal diagnosis of cACC and pACC without associated structural anomalies on ultrasound, undergoing fetal MRI. The primary outcome was the rate of additional anomalies detected at fetal MRI. Further analyses assessed the effect of type of ultrasound assessment (neurosonography vs standard axial assessment), gestational age at fetal MRI and rate of postnatally detected brain anomalies. Random-effect meta-analyses of proportions were used to analyze the data. RESULTS: Fourteen studies (798 fetuses) were included. In cases with isolated cACC, 10.9% (95% CI 4.1-20.6) and 4.3% (95% CI 1.4-8.8) additional anomalies were detected by fetal MRI and postnatally, respectively. Stratifying according to the type of ultrasound assessment, the rate of associated anomalies detected only on fetal MRI was 5.7% (95% CI 0.5-16.0) with dedicated neurosonography and 18.5% (95% CI 7.8-32.4) with a standard axial assessment. In fetuses with isolated pACC, 13.4% (95% CI 4.0-27.0) and 16.2% (95% CI 5.9-30.3) additional anomalies were detected by fetal MRI or postnatally, respectively. Stratifying according to the type of ultrasound assessment, the rate of associated anomalies detected only on fetal MRI was 11.4% (95% CI 2.7-25.0) when dedicated neurosonography was performed. Cortical and posterior fossa anomalies represented the most common anomalies missed at ultrasound with both cACC and pACC. Due to the very small number of included cases, stratification according to early (<24 weeks of gestation) and late (>24 weeks) fetal MRI could not be done for either cACC or pACC. CONCLUSIONS: The rate of associated anomalies detected exclusively at fetal MRI in isolated ACC undergoing neurosonography is lower than previously reported. Cortical and posterior fossa anomalies are among the most common anomalies detected exclusively at MRI, thus confirming the crucial role of fetal MRI in determining the prognosis of these fetuses. However, some anomalies still go undetected prenatally and this should be stressed during parental counseling.

RESUMEN

INTRODUCTION: The role of cerebroplacental ratio (CPR) or umbilicocerebral ratio (UCR) to predict adverse intrapartum and perinatal outcomes in pregnancies complicated by late fetal growth restriction (FGR) remains controversial. METHODS: This was a multicenter, retrospective cohort study involving 5 referral centers in Italy and Spain, including singleton pregnancies complicated by late FGR, as defined by Delphi consensus criteria, with a scan 1 week prior to delivery. The primary objective was to compare the diagnostic accuracy of the CPR and UCR for the prediction of a composite adverse outcome, defined as the presence of either an adverse intrapartum outcome (need for operative delivery/cesarean section for suspected fetal distress) or an adverse perinatal outcome (intrauterine death, Apgar score <7 at 5 min, arterial pH <7.1, base excess of >-11 mEq/mL, or neonatal intensive care unit admission). RESULTS: Median CPR absolute values (1.11 vs. 1.22, p = 0.018) and centiles (3 vs. 4, p = 0.028) were lower in pregnancies with a composite adverse outcome than in those without it. Median UCR absolute values (0.89 vs. 0.82, p = 0.018) and centiles (97 vs. 96, p = 0.028) were higher. However, the area under the curve, 95% confidence interval for predicting the composite adverse outcome showed a poor predictive value: 0.580 (0.512-0.646) for the raw absolute values of CPR and UCR, and 0.575 (0.507-0.642) for CPR and UCR centiles adjusted for gestational age. The use of dichotomized values (CPR <1, UCR >1 or CPR <5th centile, UCR >95th centile) did not improve the diagnostic accuracy. CONCLUSION: The CPR and UCR measured in the week prior delivery are of low predictive value to assess adverse intrapartum and perinatal outcomes in pregnancies with late FGR.

RESUMEN

Background: Placental chorioangioma is the most common benign non-trophoblastic neoplasm of the placenta. Its clinical relevance lies in the size of the tumor since larger masses cause pregnancy complications, including an unfavorable neonatal outcome. Case presentation: We report the case of a 34-year-old second gravida and nullipara at the 35th week of gestation, admitted to the gynecological department for antibiotic-resistant fever. The cardiotocography performed during hospitalization showed an abnormal fetal pattern. A 2250 g newborn was delivered by cesarean section. No complications were observed during childbirth and postpartum was insignificant. On gross inspection a white fleshy intraparenchymal mass blooming on the maternal surface was noted; routinely stained sections revealed features consistent with chorioangioma with vascular channels lined by inconspicuous endothelial cells immunoreactive for CD31 and CD133. Focal expression of CD133 was also observed in placental villi. Discussion: CD133 expression indicated the presence of stem cells in chorioangioma, suggesting their possible role in the development of mesenchymal lesions including chorioangioma.

RESUMEN

Background-Osteoporosis is characterized by defects in both quality and quantity of bone tissue, which imply high susceptibility to fractures with limitations of autonomy. Current therapies for osteoporosis are mostly concentrated on how to inhibit bone resorption but give serious adverse effects. Therefore, more effective and safer therapies are needed that even encourage bone formation. Here we examined the effect of extracellular vesicles secreted by human amniotic fluid stem cells (AFSC) (AFSC-EV) on a model of osteoporosis in vitro. Methods-human AFSC-EV were added to the culture medium of a human pre-osteoblast cell line (HOB) induced to differentiate, and then treated with dexamethasone as osteoporosis inducer. Aspects of differentiation and viability were assessed by immunofluorescence, Western blot, mass spectrometry, and histological assays. Since steroids induce oxidative stress, the levels of reactive oxygen species and of redox related proteins were evaluated. Results-AFSC-EV were able to ameliorate the differentiation ability of HOB both in the case of pre-osteoblasts and when the differentiation process was affected by dexamethasone. Moreover, the viability was increased and parallelly apoptotic markers were reduced. The presence of EV positively modulated the redox unbalance due to dexamethasone. Conclusion-these findings demonstrated that EV from hAFSC have the ability to recover precursor cell potential and delay local bone loss in steroid-related osteoporosis.

RESUMEN

PURPOSE: To investigate the value of a new cervical sonographic sign, called the jellyfish sign (JS), for predicting the risk of maternal morbidity in cases of abnormally invasive placenta (AIP) previa totalis. MATERIALS AND METHODS: Retrospective evaluation of transvaginal (TV) and transabdominal (TA) scans performed in all singleton pregnancies with placenta previa totalis. JS, i. e. the absence of the normal linear demarcation between the placenta previa and the cervix, was evaluated by TV scans. The presence/severity of AIP and outcomes of maternal morbidity were related to this sign. RESULTS: JS was noted in 8/39 (20.5 %) patients. The two analyzed groups, i. e. with and without JS, were similar. The specificity of JS in AIP diagnosis, histological findings of accreta/increta/percreta, need for caesarean hysterectomy or blood loss > 2000 ml ranges between 92 % and 96.2 %, with the PPV and NPV ranging between 71.4 % and 85.7 % and 61.3 % and 80.6 %, respectively. The JS group had a significant increase in blood loss (ml) (p = 0.003), transfusions (%) (p = 0.016), red blood cells (p = 0.002) and plasma (p = 0.002), admission to an postoperative intensive care unit (ICU) (%) (p = 0.002), hospitalization length (p < 0.001) and the need of cesarean hysterectomy (%) (p < 0.001). JS was independently correlated to cesarean hysterectomy (OR 25.6; 95 % CI 2.0:322.3, p = 0.012) and blood loss > 2000 ml (OR 16.6; 95 % CI 1.5:180.1, p = 0.021) also in a logistic regression model. CONCLUSION: JS is useful in predicting the increase in maternal morbidity: massive transfusion, admission to the ICU and cesarean hysterectomy related to intraoperative bleeding in patients with a previa AIP.

RESUMEN

OBJECTIVE: A systematic review was carried out of studies of women with endometriosis, to examine the evidence for efficacy of the use of hormonal contraception to improve disease-related pain and decrease postoperative risk of disease recurrence. METHODS: A search of the Medline/PubMed and Embase databases was performed to identify all published English language studies on hormonal contraceptive therapies (combined hormonal contraceptives [CHCs], combined oral contraceptives [COCs], progestin-only pills [POPs] and progestin-only contraceptives [POCs]) in women with a validated endometriosis diagnosis, in comparison with placebo, comparator therapies or other hormonal therapies. Main outcome measures were endometriosis-related pain (dysmenorrhoea, pelvic pain and dyspareunia), quality of life (QoL) and postoperative rate of disease recurrence during treatment. RESULTS: CHC and POC treatments were associated with clinically significant reductions in dysmenorrhoea, often accompanied by reductions in non-cyclical pelvic pain and dyspareunia and an improvement in QoL. Only two COC preparations (ethinylestradiol [EE]/norethisterone acetate [NETA] and a flexible EE/drospirenone regimen) demonstrated significantly increased efficacy compared with placebo. Only three studies found that the postoperative use of COCs (EE/NETA, EE/desogestrel and EE/gestodene) reduced the risk of disease recurrence. There was no evidence that POCs reduced the risk of disease recurrence. CONCLUSIONS: CHCs and POCs are effective for the relief of endometriosis-related dysmenorrhoea, pelvic pain and dyspareunia, and improve QoL. Some COCs decreased the risk of disease recurrence after conservative surgery, but POCs did not. There is insufficient evidence, however, to reach definitive conclusions about the overall superiority of any particular hormonal contraceptive.

RESUMEN

OBJECTIVES: The thymus has a pyramidal shape, which is best shown in coronal planes. The aim of this study was to evaluate the potential of virtual organ computer-aided analysis to estimate fetal thymus volume in normal pregnancies. METHODS: Three-dimensional volume data sets from the axial upper mediastinal section were acquired from 37 normal pregnancies between 12 and 35 weeks' gestation. Thymus volume was calculated by virtual organ computer-aided analysis by 2 separate examiners. In 12 cases, volumes were also acquired with 4-dimensional sonography and spatiotemporal image correlation software to assess the variability in thymus size between the systolic and diastolic periods of fetal heart motion. Linear regression analysis was used to assess the relationship between the fetal thymus volume and gestational age. Paired Student t tests were used to evaluate both the level of agreement for interobserver and intraobserver variability and the difference between diastolic and systolic thymus volumes. RESULTS: Identification of the borders of the thymus and calculation of its volume were successful in 28 patients (77.7%). Statistically significant linear growth of the thymus during pregnancy, from 12 to 35 weeks, was found. The growth coefficient for each gestational age was 0.43 (95% confidence interval, 0.355 to 0.504; P < .001). The difference in thymus size between systole and diastole was minor (0.0798 cm(3); 95% confidence interval, -0.044 to 0.203 cm(3)). Interobserver and intraobserver variability was not statistically significant. CONCLUSIONS: Although the thymus has a complex shape, it was possible to determine its borders and to calculate its volume by virtual organ computer-aided analysis in 77.7% of cases. Linear growth during pregnancy was found, and the minor changes during systole and diastole could be explained by condensation of the soft tissue of the thymus secondary to cardiac activity.

RESUMEN

Branchio-oto-renal syndrome combines branchial arch defects, hearing impairment and renal malformations or hypoplasia. Due to the high phenotypic variability, prenatal diagnosis has a limited prognostic value in mutation-positive cases. We report the first branchio-oto-renal syndrome molecular prenatal diagnosis and ultrasonographic follow-up, showing a normal renal growth until the 24th week of pregnancy, a growth deceleration during the third trimester and a renal volume recovery during the first months of life.

RESUMEN

Arboleda-Tham syndrome (ARTHS, MIM 616268) is a rare genetic disease, due to a pathogenic variant of Lysine (K) Acetyltransferase 6A (KAT6A) with autosomal dominant inheritance. Firstly described in 2015, ARTHS is one of the more common causes of undiagnosed syndromic intellectual disability. Due to extreme phenotypic variability, ARTHS clinical diagnosis is challenging, mostly at early stage of the disease. Moreover, because of the wide and unspecific spectrum of ARTHS, identification of the syndrome during prenatal life rarely occurs. Therefore, reported cases of KAT6A syndrome have been identified primarily through clinical or research exome sequencing in a gene-centric approach. In order to expands the genotypic and phenotypic spectrum of ARTHS, we describe prenatal and postnatal findings in a patient with a novel frameshift KAT6A pathogenic variant, displaying a severe phenotype with previously unreported clinical features.

RESUMEN

Human amniotic fluid cells (hAFSCs) are a fascinating foetal cell-type that have important stem cell characteristics; however, they are a heterogeneous population that ranges from totally differentiated or progenitor cells to highly multipotent stem cells. There is no single approach to isolating the stem cell component, but the selection of a subpopulation of hAFSCs expressing c-Kit is widely employed, while a deep characterization of the two populations is still lacking. Here we performed single-cell and bulk RNAseq analysis to compare the gene expression profiles of adherent amniotic fluid cells and their subpopulation c-Kit+. Information deriving from this high throughput technology on the transcriptome was then confirmed for specific targets with protein expression experiments and functional analysis. In particular, transcriptome profiling identified changes in cellular distribution among the different clusters that correlated with significant differential expression in pathways related to stemness, proliferation, and cell cycle checkpoints. These differences were validated by RT-PCR, immunofluorescence, WB, and cell cycle assays. Interestingly, the two populations produced secretomes with different immune-modulating and pro-regenerative potentials. Indeed, the presence of TGFß, HGF, IDO was higher in EVs deriving from c-Kit+ cells, unlike IL-6. These results suggest the existence of deep intra-population differences that can influence the stemness profile of hAFSCs. This study represents a proof-of-concept of the importance of selecting c-Kit positive fractions with higher potential in regenerative medicine applications.

RESUMEN

OBJECTIVE: To study how adenomyosis changes during pregnancy and to possibly correlate these changes to maternal and fetal outcomes. METHODS: Retrospective exploratory cohort study including 254 women with a pre-conceptional/first-trimester scan to document adenomyosis and known obstetric outcome. If visible, adenomyosis signs were documented in each trimester and postpartum. Mann-Whitney U tests or χ2 tests were used for continuous and categorical variables, respectively. RESULTS: A globular uterus was reported in 79% (n = 52) of women with adenomyosis in the first trimester, in 38% (n = 20) and 2% (n = 1) of women in the second and third trimesters, respectively, and postpartum in 77% (n = 34) of women. Asymmetrical thickening (n = 20, 30%) and cysts (n = 15, 23%) were only visible in 1st trimester. Adenomyosis was associated with miscarriage (odds ratio [OR] 5.9, 95% confidence interval [CI] 2.4-14.9, P < 0.001) also in normal conception only (OR 5.1, 95% CI 1.8-14.2, P = 0.002) or adjusting for maternal age (adjusted OR 5.9, 95% CI 2.3-15.2, P < 0.001). Gestational age at delivery was lower in adenomyosis (P = 0.004); the cesarean section rate was higher than in controls (OR 2.5, 95% CI 1.3-4.8, P = 0.007) also adjusting for age (adjusted OR 2.07, 95% CI 1.06-4.08, P = 0.035). CONCLUSIONS: Signs of adenomyosis were visible but progressively disappeared in pregnancy; adenomyosis was associated with an increased risk of early miscarriage. Prospective studies are needed to confirm our results.

RESUMEN

OBJECTIVES: The purpose of this study was to evaluate the feasibility of visualization and measurement of the pericallosal artery during early stages of gestation. METHODS: The study group comprised 80 pregnant women between 12 and 21 weeks' gestation who attended our ultrasound unit. Transabdominal or transvaginal sonography was performed to obtain the optimal angle of a midsagittal section. High-definition flow power Doppler imaging was used to visualize the pericallosal artery. In a sagittal plane, the lengths of the pericallosal artery were measured using a straight line to connect the most anterior and posterior points. All patients were reexamined at a later stage of pregnancy to verify the existence of the corpus callosum and pericallosal artery. RESULTS: Visualization of the pericallosal artery was evident in 71 fetuses, in all of whom the biparietal diameter was greater than 20 mm. We were able to verify normal anatomy and the existence of the pericallosal artery in these fetuses between 30 and 32 weeks' gestation. A positive linear association was found between the length of the pericallosal artery and the gestational age (R(2) = 0.95) and the biparietal diameter at each gestational age (R(2) = 0.99). CONCLUSIONS: Our data show that it is feasible to visualize and measure the pericallosal artery from an early stage of gestation, and this measurement could be an indirect indication of normal corpus callosum development.

RESUMEN

Molar degeneration of the trophoblast is a rare, yet possible, complication of pregnancies. Complete hydatidiform mole is the most common histological type among all trophoblastic tumors and it is the result of the fertilization of an empty oocyte from two sperms or by one sperm that then duplicates. Complete mole is characterized by hydropic degeneration of abnormal chorionic villi, diffused trophoblast hyperplasia and the absence of identifiable embryonic or fetal tissue; the hyperplastic trophoblast justifies the common finding of high serum beta HCG levels. Twin molar pregnancy is an uncommon obstetric event, and even less frequent are triplet/quadruplet molar pregnancies. We hereby report a case of a complete hydatidiform mole with two coexistent fetuses in a triplet pregnancy after in vitro fertilization procedure; the pregnancy ended with a therapeutic abortion. During the follow-up, the serum beta human chorionic gonadotropin concentration started to rise, and the diagnosis of post-molar gestational trophoblastic neoplasia was made and consequently methotrexate treatment was started. Due to the rarity of this condition, there are no specific guidelines for the management of multiple pregnancies complicated by complete hydatidiform mole. We therefore performed a review of the literature including all reported cases of triplets/quadruplets pregnancies complicated by complete mole of a fetus focusing on ultrasound diagnosis, treatment and outcomes of this rare and life-threatening condition.

RESUMEN

Background and Aims: This is the first national population-based report about prenatal diagnosis for families with a history of facioscapulohumeral muscular dystrophy (FSHD), a complex hereditary disease. The incomplete disease penetrance and the phenotypic heterogeneity observed in carriers of D4Z4 alleles of reduced size, the FSHD molecular hallmark, make the estimate of genetic risk problematic. Methods: We considered all requests of preconception counseling and prenatal diagnosis received between January 2008 and December 2020 by the genetic counseling service associated with the Italian National Registry for FSHD (INRF). A multidisciplinary team managed the clinical and molecular data of each family. Results: Between 2008 and 2020, 60 couples required preconception counseling (PC) for FSHD. In 52 couples was observed at least one partner carried a D4Z4 reduced allele (DRA). Out of these 52 couples, 47 had a follow-up visit routine yearly. Out of these 47, 26 (55.3%) couples had children: eight asked for prenatal diagnosis (PND), two had assisted reproduction by heterologous in vitro fertilization (IVF), and 16 did not require further assistance. Regarding PND, 50 prenatal analyses were performed for 36 couples. The test resulted positive in 27 pregnancies, 12 (44.4%) were terminated, and 15 (55.6%) were carried to term. Conclusion: The different choices made by the couples show the importance of an integrated approach to support genetic counseling for FSHD. These results remark the relevance of the clinical and molecular investigation of the extended family, preferably before conception.

RESUMEN

OBJECTIVE: To investigate the effect of a quality improvement project with an educational/motivational intervention in northern Italy on the implementation of the trial of labor after cesarean section (CS). METHOD: A pre-post study design was used. Every birth center (n = 23) of the Emilia-Romagna region was included. Gynecologist opinion leaders were first trained about Italian CS recommendations. Barriers to implementation were discussed and shared. Educational/motivational interventions were implemented. Data of multipara with previous CS, with a single, cephalic pregnancy at term, were collected during two periods, before (2012-2014) and after (2017-2019) the intervention (2015-2016). The primary outcome was the rate of vaginal birth after CS (VBAC) and perinatal outcomes. RESULTS: A total of 20 496 women were included. The VBAC rate increased from 18.1% to 23.1% after intervention (P < 0.001). The likelihood of VBAC-adjusted for age 40 years or older, Caucasian, body mass index (BMI, calculated as weight in kilograms divided by the square of height in meters) at least 30, previous vaginal delivery, and labor induction-was increased by the intervention by 42% (odds ratio 1.42, 95% confidence interval 1.31-1.54). Neonatal well-being was improved by intervention; neonates requiring resuscitation decreased from 2.1% to 1.6% (P = 0.001). CONCLUSION: Educating and motivating gynecologists toward the trial of labor after CS is worth pursuing. Health quality improvement is demonstrated by increased VBAC even improving neonatal well-being.
