Objectives: To compare the utilization of prenatal services between immigrant and Italian women during the COVID-19 pandemic. Methods: A cross-sectional survey was conducted at 3 maternity care centers in Italy. Results: We included 1,312 women, 1,198 (91.3%) were Italian and 114 (8.7%) were immigrants. A significantly higher proportion of Italians underwent 8 or more prenatal care visits (64.4% vs. 54.4%, p = 0.03) and more immigrants than Italians attended their appointments at hospital settings (45% vs. 18%, p < 0.001). Regarding prenatal course, Italians were more likely than immigrants to attend a non-hospital setting or an online class (49.6% and 30.2% vs. 34.9% and 11.6%, p = 0.008). A higher influenza vaccine uptake among immigrants compared with Italians was observed (39.5% vs. 19.8%, p < 0.001). Among women not receiving certain prenatal services, immigrants were more likely to state COVID-19 pandemic was the main reason for non-compliance. Conclusion: Immigrant pregnant women were more likely to receive prenatal services at a hospital setting than their Italian counterparts. Among women who did not comply with prenatal services, immigrants were more likely to cite the pandemic as their main reason.

Italy has been one of the hardest hit countries in the European Union since the beginning of the SARS-CoV-2 pandemic, and Regione Lombardia (RL) has reported the largest number of cases in the country. This population-based retrospective study analyzed RL records of 122,942 pregnant women to describe SARS-CoV-2 vaccination uptake in the pregnant population, to compare pregnant women vaccine uptake vs. women of childbearing age and to evaluate the impact of vaccination status in pregnant women on admissions to intensive care units during 2021. Vaccination uptake according to citizenship and educational level and the comparison between pregnant and non-pregnant women was performed by Z test. A logistic regression was performed to compare age groups. Out of 122,942 pregnant women, 79.9% were vaccinated at the end of 2021. The vaccine uptake rate was significantly lower in pregnant versus non-pregnant women but increased after the issuing of official recommendations. Vaccine administration was significantly higher among pregnant women with Italian citizenship and with a high level of education in all trimesters. In conclusion, the role of official recommendations with explicit communication about the importance and safety of vaccination in pregnancy is critical to obtain trust and acceptance among pregnant women.

Folic acid (FA) supplementation prevents neural tube defects (NTDs), but the effects on other reproductive outcomes are unclear. While common recommendation is 0.4 mg/day in addition to regular nutrition, the most appropriate dose of FA is still under debate. We investigated the effects of a higher dose of periconception FA on reducing adverse reproductive outcomes. In this multicenter double-blind randomized controlled trial (RCT), 1060 women (aged 18–44 years and planning a pregnancy) were randomly assigned to receive 4.0 mg or 0.4 mg of FA daily. The primary outcome was the occurrence of congenital malformations (CMs). A composite outcome including one or more adverse pregnancy outcomes was also evaluated. A total of 431 women had a natural conception within 1 year. The primary outcome occurred in 8/227 (3.5%) women receiving 4.0 mg FA and 9/204 (4.4%) women receiving 0.4 mg FA (RR 0.80; 95%CI 0.31 to 2.03). The composite outcome occurred in 43/227 (18.9%) women receiving 4.0 mg FA and 75/204 (36.8%) women receiving 0.4 mg FA (RR 0.51; 95%CI 0.40 to 0.68). FA 4.0 mg supplementation was not associated with different occurrence of CMs, compared to FA 0.4 mg supplementation. However, FA 4.0 mg supplementation was associated with lower occurrence of other adverse pregnancy outcomes.

Background Adverse neurodevelopmental outcomes and MRI alterations are reported in infants born after fetal growth restriction (FGR). This study evaluates the additional role of FGR over prematurity in determining brain impairment. Methods Retrospective observational study comparing 48 FGR and 36 appropriate for gestational age infants born between 26 and 32 weeks’ gestation who underwent a cerebral MRI at term equivalent age. Exclusion criteria were twins, congenital anomalies, and findings of overt brain lesions. Main outcomes were total maturation score (TMS) and cerebral areas independently measured by two neuro-radiologists and Griffiths or Bayley scale III scores at median age of 2 years. Results TMS was not significantly different between the groups. Inner calvarium and parenchyma’s areas were significantly smaller in FGR cases. There were no significant differences in the average quotient scores. A positive correlation between parenchyma area and cognitive score was found ( r  = 0.372, p  = 0.0078) and confirmed after adjusting for sex, gestational age, and birth weight ( p  = 0.0014). Among FGR, the subgroup with umbilical arterial Doppler velocimetry alterations had significantly worse gross motor scores ( p  = 0.005). Conclusions FGR plays additional role over prematurity in determining brain impairment. An early structural dimensional MRI evaluation may identify infants who are at higher risk. Impact Fetal growth-restricted infants showed smaller cerebral parenchymal areas than preterm controls. There is a positive correlation between the parenchyma area and the cognitive score. These results highlight the already known link between structure and function and add importance to the role of a structural dimensional MRI evaluation even in the absence of overt brain lesions.

IntroductionFollowing the detection of fetal growth restriction, there is no consensus about the criteria that should trigger delivery in the late preterm period. The consequences of inappropriate early or late delivery are potentially important yet practice varies widely around the world, with abnormal findings from fetal heart rate monitoring invariably leading to delivery. Indices derived from fetal cerebral Doppler examination may guide such decisions although there are few studies in this area. We propose a randomised, controlled trial to establish the optimum method of timing delivery between 32 weeks and 36 weeks 6 days of gestation. We hypothesise that delivery on evidence of cerebral blood flow redistribution reduces a composite of perinatal poor outcome, death and short-term hypoxia-related morbidity, with no worsening of neurodevelopmental outcome at 2 years.Methods and analysisWomen with non-anomalous singleton pregnancies 32+0 to 36+6 weeks of gestation in whom the estimated fetal weight or abdominal circumference is <10th percentile or has decreased by 50 percentiles since 18–32 weeks will be included for observational data collection. Participants will be randomised if cerebral blood flow redistribution is identified, based on umbilical to middle cerebral artery pulsatility index ratio values. Computerised cardiotocography (cCTG) must show normal fetal heart rate short term variation (≥4.5 msec) and absence of decelerations at randomisation. Randomisation will be 1:1 to immediate delivery or delayed delivery (based on cCTG abnormalities or other worsening fetal condition). The primary outcome is poor condition at birth and/or fetal or neonatal death and/or major neonatal morbidity, the secondary non-inferiority outcome is 2-year infant general health and neurodevelopmental outcome based on the Parent Report of Children’s Abilities-Revised questionnaire.Ethics and disseminationThe Study Coordination Centre has obtained approval from London-Riverside Research Ethics Committee (REC) and Health Regulatory Authority (HRA).

Background: Itraconazole is an effective fungal treatment; however, there are few human data on prenatal exposure. Objectives: To evaluate the major malformation rate in itraconazole prenatally exposed infants. The secondary objective includes evaluation of the pregnancy outcome. Methods: A prospective cohort study was conducted from January 2002 to October 2006 in women who called two Italian Teratology Information Services (TIS). Pregnant women who were exposed to itraconazole during the first trimester and gave informed consent were matched with a contemporary group of pregnant women who contacted the TIS because they had undergone a non-teratogenic drug exposure during the first trimester. Information was obtained via a structured questionnaire at the time of the initial call to the TIS and no earlier than 1 month after delivery. A trained operator conducted the interview. The main outcome measure was information about major congenital anomalies, type of delivery, birth weight, and any pregnancy or neonatal complications. Results: Data were collected on 206 women who called the TIS because of first-trimester exposure to itraconazole, and 207 controls. There were no significant differences in terms of major congenital anomalies in the exposed group versus the control group (3/163 [1.8%] vs 4/190 [2.1%], respectively). There was no statistical difference in the rate of vaginal delivery between the exposed and control groups (101/162 [62.3%] vs 102/190 [53.8%]), premature birth (11/162 [6.8%] vs 15/190 [7.9%]), low birth weight (1/152 [0.7%] vs 4/175 [2.3%]) and high birth weight (10/152 [6.5%] vs 7/175 [4.0%], respectively). The rates of live births (163/206 [79.1%] vs 190/207 [91.8%]), spontaneous abortion (23/206 [11.2%] vs 10/207 [4.8%]) and termination of pregnancy (19/206 [9.2%] vs 7/207 [3.4%] in the exposed and control groups, respectively) were significantly different (p<0.05). Conclusion: First-trimester itraconazole-exposed infants were not at increased risk of major congenital anomalies, but the rates of spontaneous and induced abortion were higher in the exposed group versus the control group. Larger studies are warranted to confirm these observations.

The intracoelomic route for in utero hematopoietic stem cell transplantation has been evaluated in pre-immune fetal sheep and the engraftment characteristics defined. Twelve ovine fetuses (gestational ages: 40–45 days) received intracoelomic transplants of human CD3-depleted (50 × 10 6 per lamb) or CD34-selected (1–2 × 10 5 per lamb) cord blood hematopoietic stem cells. Engraftment was evaluated from cell suspension of the liver, spleen, bone marrow and thymus by flow cytometry, cloning assays and polymerase chain reaction (PCR) analysis for human β 2 -microglobulin gene. The engraftment of liver samples was also evaluated by reverse transcriptase-polymerase chain reaction (RT-PCR), fluorescent in situ hybridization (FISH) and immunohistochemistry. Four fetuses (33%) aborted shortly after intracoelomic transplantation and were not evaluable for engraftment. Engraftment was detected in 4 fetuses obtained from cesarean delivery on day 70 after transplantation of CD3-depleted cord blood cells. The degree of engraftment in these 4 fetuses ranged from 6 to 22% in the different organs (as revealed by antigenic analysis of human CD45 with flow cytometry). Three fetuses obtained after cesarean section at 102 (No. 435184) and 105 (Nos 915293, 037568) days and 1 fetus delivered at term, which received CD34-selected cord blood cells, had human engraftment with 10, 32, 20 and 10% CD45+ cells in bone marrow, respectively. A further check of human chimerism was done at 1 year after birth of the fetus delivered at term and 7.6% of bone marrow chimerism was detected. In 6 out of 8 fetuses evaluable for human engraftment, chimerism was confirmed by PCR analysis for human β 2 -microglobulin which also identified human cells in brain, spinal cord, heart, lung and skeletal muscle. On liver samples, FISH and RT-PCR confirmed the xenograft of human cells and the immunohistochemical analysis detected human markers of hematopoietic and hepatic lineage of differentiation. This preliminary study indicates that intracoelomic transplantation of human hematopoietic stem cells in fetal lambs is feasible and effective in terms of hematopoietic engraftment.

Background The Short Physical Performance Battery (SPPB) is a well-established tool to assess lower extremity physical performance status. Its predictive ability for all-cause mortality has been sparsely reported, but with conflicting results in different subsets of participants. The aim of this study was to perform a meta-analysis investigating the relationship between SPPB score and all-cause mortality. Methods Articles were searched in MEDLINE, the Cochrane Library, Google Scholar, and BioMed Central between July and September 2015 and updated in January 2016. Inclusion criteria were observational studies; >50 participants; stratification of population according to SPPB value; data on all-cause mortality; English language publications. Twenty-four articles were selected from available evidence. Data of interest (i.e., clinical characteristics, information after stratification of the sample into four SPPB groups [0–3, 4–6, 7–9, 10–12]) were retrieved from the articles and/or obtained by the study authors. The odds ratio (OR) and/or hazard ratio (HR) was obtained for all-cause mortality according to SPPB category (with SPPB scores 10–12 considered as reference) with adjustment for age, sex, and body mass index. Results Standardized data were obtained for 17 studies ( n  = 16,534, mean age 76 ± 3 years). As compared to SPPB scores 10–12, values of 0–3 (OR 3.25, 95%CI 2.86–3.79), 4–6 (OR 2.14, 95%CI 1.92–2.39), and 7–9 (OR 1.50, 95%CI 1.32–1.71) were each associated with an increased risk of all-cause mortality. The association between poor performance on SPPB and all-cause mortality remained highly consistent independent of follow-up length, subsets of participants, geographic area, and age of the population. Random effects meta-regression showed that OR for all-cause mortality with SPPB values 7–9 was higher in the younger population, diabetics, and men. Conclusions An SPPB score lower than 10 is predictive of all-cause mortality. The systematic implementation of the SPPB in clinical practice settings may provide useful prognostic information about the risk of all-cause mortality. Moreover, the SPPB could be used as a surrogate endpoint of all-cause mortality in trials needing to quantify benefit and health improvements of specific treatments or rehabilitation programs. The study protocol was published on PROSPERO (CRD42015024916).

Background Ageing is accompanied by a progressive loss of skeletal muscle mass and strength, potentially determining the insurgence of sarcopenia. Evidence suggests that motoneuron and neuromuscular junction (NMJ) degeneration contribute to sarcopenia pathogenesis. Seeking for strategies able to slow down sarcopenia insurgence and progression, we investigated whether a 2‐year mixed‐model training involving aerobic, strength and balance exercises would be effective for improving or preserving motoneuronal health and NMJ stability, together with muscle mass, strength and functionality in an old, sarcopenic population. Methods Forty‐five sarcopenic elderly (34 females; 11 males) with low dual‐energy X‐ray absorptiometry (DXA) lean mass and Short Physical Performance Battery (SPPB) score <9 were randomly assigned to either a control group [Healthy Aging Lifestyle Education (HALE), n = 21] or an intervention group [MultiComponent Intervention (MCI), n = 24]. MCI trained three times per week for 2 years with a mix of aerobic, strength and balance exercises matched with nutritional advice. Before and after the intervention, ultrasound scans of the vastus lateralis (VL), SPPB and a blood sample were obtained. VL architecture [pennation angle (PA) and fascicle length (Lf)] and cross‐sectional area (CSA) were measured. As biomarkers of neuronal health and NMJ stability status, neurofilament light chain (NfL) and C‐terminal agrin fragment (CAF) concentrations were measured in serum. Differences in ultrasound parameters, NfL and CAF concentration and physical performance between baseline and follow‐up were tested with mixed ANOVA or Wilcoxon test. The relationship between changes in physical performance and NfL or CAF concentration was assessed through correlation analyses. Results At follow‐up, MCI showed preserved VL architecture (PA, Lf) despite a reduced CSA (−8.4%, P < 0.001), accompanied by maintained CAF concentration and ameliorated overall SPPB performance (P = 0.007). Conversely, HALE showed 12.7% decrease in muscle CSA (P < 0.001), together with 5.1% and 5.5% reduction in PA and Lf (P < 0.001 and P = 0.001, respectively), and a 6.2% increase in CAF (P = 0.009) but improved SPPB balance score (P = 0.007). NfL concentration did not change in either group. In the population, negative correlations between changes in CAF concentration and SPPB total score were found (P = 0.047), whereas no correlation between NfL and SPPB variations was observed. Conclusions The present findings suggest that our 2‐year mixed aerobic, strength and balance training seemed effective for preventing the age and sarcopenia‐related increases in CAF concentration, preserving NMJ stability as well as muscle structure (PA and Lf) and improving physical performance in sarcopenic older individuals.

Populated coastal areas are exposed to emissions from harbour-related activities (ship traffic, loading/unloading, and internal vehicular traffic), posing public health issues and environmental pressures on climate. Due to the strategic geographical position of Italy and the high number of ports along coastlines, an increasing concern about maritime emissions from Italian harbours has been made explicit in the EU and IMO (International Maritime Organization, London, UK) agenda, also supporting the inclusion in a potential Mediterranean emission control area (MedECA). This work reviews the main available outcomes concerning shipping (and harbours’) contributions to local air quality, particularly in terms of concentration of particulate matter (PM) and gaseous pollutants (mainly nitrogen and sulphur oxides), in the main Italian hubs. Maritime emissions from literature and disaggregated emission inventories are discussed. Furthermore, estimated impacts to air quality, obtained with dispersion and receptor modeling approaches, which are the most commonly applied methodologies, are discussed. Results show a certain variability that suggests the necessity of harmonization among methods and input data in order to compare results. The analysis gives a picture of the effects of this pollution source, which could be useful for implementing effective mitigation strategies at a national level.
