Parental stress, depression, anxiety and participation to care in neonatal intensive care units: results of a prospective study in Italy, Brazil and Tanzania.

BACKGROUND: Studies comparing the frequency of different mental health conditions across different settings and evaluating their association with parental participation in newborn care are lacking. We aimed at evaluating the frequency of parental stress, anxiety and depression, along with the level of participation in newborn care, among parents of newborns in Italy, Brazil and Tanzania. METHODS: Parental stress, anxiety, depression and participation in care were assessed prospectively in parents of newborns in eight neonatal intensive care units (NICUs) utilising: the Parental Stressor Scale in NICU (PSS:NICU); the Edinburgh Postnatal Depression Scale (EPDS) and EPDS-Anxiety subscale (EPDS-A); the Index of Parental Participation in NICU (IPP-NICU). Univariate and multivariate analyses were conducted. RESULTS: Study outcomes were assessed on 742 parents (Brazil=327, Italy=191, Tanzania=224). Observed scores suggested a very high frequency of stress, anxiety and depression, with an overall estimated frequency of any of the mental health condition of 65.1%, 52.9% and 58.0% in Brazil, Italy, Tanzania, respectively (p<0.001). EPDS scores indicating depression (cut-off: ≥13 for Brazil and Tanzania, ≥12 for Italy) were significantly more frequent in Tanzania (52.3%) when compared with either Brazil (35.8%) and Italy (33.3%) (p<0.001). Parental participation in care was also significantly higher in Tanzania (median IPP-NICU=24) than in the other two countries (median=21 for Brazil, 18 for Italy, p<0.001). Severe stress (PSS:NICU ≥4) was significantly more frequently reported in Brazil (22.6%), compared with Italy (4.7%) and Tanzania (0%, p<0.001). Factors independently associated with either parental stress, anxiety or depression varied by country, and a significant association with parental participation in care was lacking. CONCLUSIONS: Study findings suggest that parental stress, anxiety and depression are extremely frequent in NICUs in all countries despite diversity in the setting, and requiring immediate action. Further studies should explore the appropriate level of parental participation in care in different settings.

Cerebral Synchronization Between Mothers and Their Newborns During Breastfeeding.

Introduction: Breastfeeding is a fundamental biological function in mammals, allowing the progeny to develop in a physiological way. A physical and emotional dialog between mothers and offspring during breastfeeding has been described as part of the attachment relationship, and a synchronicity between maternal and neonatal brains can be hypothesized. This study aimed to assess if neonatal and maternal cortical areas activated during breastfeeding are functionally synchronized since the second day of life. Materials and Methods: Twenty mothers and their term newborns were enrolled. Cortical activation during breastfeeding was identified by multichannel near-infrared spectroscopy, which detects changes in haemoglobin concentration from multiple cortical regions. Functional activity was simultaneously detected (hyperscanning) in mothers and newborns' frontal and motor/primary somatosensory cortical areas during the first 5 minutes of breastfeeding. Cluster analysis and Student's t test were used to detect oxygenated haemoglobin increase, as cortical activation estimate. Wavelet transform coherence (WTC) analysis was used to identify a possible synchronization between maternal and neonatal activated cortical regions. Results: Mothers showed an activation of the central motor/primary somatosensory cortex, above the sagittal fissure. In newborns, the bilateral frontal cortex was activated. WTC analysis revealed two different cyclical synchronizations between mothers and infants' activated cortical regions. Conclusions: Such evidence may reflect a very early common sharing of experiences, possibly associated with reciprocal dynamic motor adjustments, hormonal coregulation, and somatic stimulations and sensations. The observed cyclical neural synchronization, between the mother and her newborn's cortex during breastfeeding, may play an important role in promoting their bonding.

Parental stress, depression, anxiety and participation in care in neonatal intensive care unit: a cross-sectional study in Italy comparing mothers versus fathers.

BACKGROUND: This study aimed at documenting the levels of stress, depression, anxiety and participation in care among mothers versus fathers of newborns hospitalised in a third-level neonatal intensive care unit (NICU) in Northern Italy. METHODS: Parental stress, depression and anxiety were assessed by the Parental Stressor Scale in NICU (PSS:NICU), the Edinburgh Postnatal Depression Scale (EPDS) and the State-Trait Anxiety Inventory (STAI). Participation in care was evaluated with the Index of Parental Participation. Differences between mothers and fathers were assessed with the Mood's median test and z-test, respectively for continuous and discrete variables. Multivariate analyses controlling for potential confounders were performed to confirm gender differences. RESULTS: 191 parents (112 mothers and 79 fathers) were enrolled. Mothers reported significantly higher median scores for stress (2.9 vs 2.2, p<0.001) and trait anxiety (37 vs 32, p=0.004) and higher depression rates (EPDS ≥12: 43.8% vs 19.0%, p<0.001). 'High stress' (PSS:NICU ≥3) was reported by 45.5% of mothers compared with 24.1% of fathers (p=0.004). The frequency of the three conditions simultaneously was significantly higher among mothers (20.0% vs 3.8%, p=0.016), with the vast majority of mothers (76.0%) suffering from at least one condition compared with less than half of fathers (45.3%, p<0.001). Participation in care was more frequent in mothers (median score: 19 vs 15, p<0.001), with the exception of activities related to advocacy (median 5 vs 4, p=0.053). In a multivariate analysis, gender differences in mental health outcomes did not change. CONCLUSIONS: Routine screening of mental distress among parents of infants in NICU is warranted, and gender differences need to be acknowledged in order to deliver tailored support and to promote collaboration with the family of vulnerable newborns. Knowledge and skills on how to prevent and cope with mental distress of parents should be part of the core curriculum of staff working in NICU.

Current hospital policies on breastfeeding: a survey from Italy.

BACKGROUND: The availability of an appropriate newborn feeding policy is an essential component of the promotion of breastfeeding in health facilities. The Italian Society of Neonatology (SIN) and the Italian Society of Paediatrics (SIP) have run an online survey among Maternity Hospitals to explore the existing breastfeeding policies and their characteristics. METHODS: Between February and April 2023, an online survey was carried out among 110 Italian maternity hospitals with a Neonatal Intensive Care Unit (NICU). RESULTS: Forty-nine Maternity Hospitals completed the online questionnaire. Twenty out of 49 (40.8%) reported to have a breastfeeding policy. When a policy is available, its quality appears to be suboptimal because of lack of inclusion of a family representative in the policy working group, limited options for translating breastfeeding policy into minority languages, lack of periodic assessment of their implementation. CONCLUSION: Currently, only a limited number of Italian Maternity Hospitals have developed a breastfeeding policy. Additional efforts are needed for their improvement as well as implementation.

Ultrasonographic measurements of the inferior vena cava diameter in newborns: is it a useful tool for choosing an umbilical venous catheter?

Objectives: The primary outcomes of this study were to evaluate the diameters of the inferior vena cava (IVC) in a cohort of newborns and the correlation between newborn weight and IVC diameter. The secondary outcome was to evaluate the concordance between the measurements performed by the two investigators. Methods: Two blind examiners performed an ultrasonographic (US) evaluation of the IVC diameter in neonates with a weight ranging from 2 to 4 kg. The exclusion criteria included hemodynamic instability, known vascular malformations, and major congenital malformations. Results: A total of 143 neonates were enrolled between June 2019 and January 2021. All the US examinations were performed in the first 3 days of life. After dividing the patients into two groups according to their weight at the time of examination (2.0-2.99 kg and 3.0-4.0 kg), the median IVC diameters measured by examiner 1 were 3.1 mm (interquartile range 2.8-3.4) and 3.4 mm (interquartile range 2.9-3.8) (p = 0.003) for the two groups, respectively. The median IVC diameters measured by examiner 2 were 3.1 mm (interquartile range 2.6-3.3) and 3.3 mm (interquartile range 2.8-3.8) (p = 0.004) for the two groups, respectively. The intraclass correlation coefficient was 0.93 (95% CI: 0.90-0.95). Conclusion: The IVC diameter values varied widely from 1.2 to 5.2 mm in newborns weighing 2-4 kg, and a low correlation between newborn weight and IVC diameter was found, so measuring IVC diameter may be a recommended step prior to inserting a umbilical venous catheter (UVC). The concordance between operators was good. We contemplated that the IVC diameter could be a potentially useful tool to identify the most appropriate UVC, thus reducing the risk of catheter-related thrombosis.

Ten years of a neonatal screening program for hemoglobinopathies in Friuli-Venezia Giulia: first regional experience in Italy.

BACKGROUND: Hemoglobinopathies are the commonest genetic defect worldwide (7% of the world's population has at least one hemoglobin mutation). Although prenatal screening for hemoglobinopathies is not obligatory during pregnancy in Italy, it is offered to women by the Italian National Health Service in the pre-conception phase. The screening of newborns is a valid alternative, and has been adopted in various European countries, albeit in a piecemeal fashion. Neonatal screening has the advantage of providing early diagnosis of a hemoglobinopathy. Here we report the findings from the experience with neonatal screening in Friuli-Venezia Giulia since 2010. MATERIALS AND METHODS: The hemoglobinopathy screening project in Friuli-Venezia Giulia, a Region in north Italy, began in November 2010. High-performance liquid chromatography was performed on dried blood spot samples collected by obstetric nurses from neonates within 5-8 days after birth. RESULTS: From 2010 to 2019, 11,956 newborns were screened, and abnormal hemoglobin was found in 519 of them (4.34%): the variants identified included HbS, HbC, HbD, HbE and HbX. More specifically, the HbS variant was observed in 347 (2.9%) newborns and the homozygous pattern was identified in 24 (0.2%) cases. The screening also detected two cases of ß-thalassemia major. DISCUSSION: We report our experience of 10 years of screening newborns for hemoglobinopathies in the Region of Friuli-Venezia Giulia, in which 7.7% of people come from malaria-endemic areas. Increased mobility and migratory flows bringing in hemoglobinopathy carriers from endemic areas have led to an increase in mutations in non-malarial countries, with a current incidence of around 4% in the newborns we tested. This means that hemoglobinopathies can be described as a rare condition. Our data show that incidence rates are comparable to those of other inherited disorders such as phenylketonuria, thereby justifying the inclusion of the test for hemoglobinopathies into screening programs for rare diseases.

Beckwith-Wiedemann syndrome and twinning: case report and brief review of literature.

BACKGROUND: Beckwith-Wiedemann syndrome (BWS, OMIM #130,650) is a pediatric overgrowth disorder involving a predisposition to tumor development. Although the clinical management of affected patients is well established, it is less clear how to handle with the cases of siblings of affected patients, since the prevalence of the condition in twins (1:1000) is ten times higher than in singletones (1:10000). CASE PRESENTATION: We report the case of a premature twin patient who during her follow-up develops a clinical phenotype compatible with BWS, genetically confirmed in blood. However, the methylation alteration characteristic of the condition was also found in the almost phenotypically normal sibling, making it challening her management. CONCLUSION: Through our case report we highlight how the diagnosis of BWS can be made without any prenatal suspicion and we propose a review of the literature on how to manage siblings of affected patients in twinning situation.

Obliterated cavum septi pellucidi: is it always a benign finding? A case report and narrative review of the literature.

OBJECTIVE: The septum pellucidum is a virtual cavity located at the anterior part of the brain midline, which only in fetal life has a certain amount of fluid inside. The presence of an obliterated cavum septi pellucidi (oCSP) in the prenatal period is poorly described in the literature but, nevertheless, it constitutes an important clinical dilemma for the fetal medicine specialist in terms of significance and prognosis. Moreover, its occurrence is increasing maybe because of the widespread of high-resolution ultrasound machine. The aim of this work is to review the available literature regarding the oCSP along with the description of a case-report of oCSP with an unexpected outcome. METHODS: A search of the literature through Pubmed was performed up to December 2022 with the aim to identify all cases of oCSP previously described, using as keywords "cavum septi pellucidi," "abnormal cavum septi pellucidi," "fetus," and "septum pellucidum." Along with the narrative review, we describe a case-report of oCSP. RESULTS: A 39 years old woman was diagnosed with a nuchal translucency between the 95° and 99° centile in the first trimester and an oCSP and "hookshaped" gallbladder at 20 weeks. Left polymicrogyria was found at fetal magnetic resonance imaging (MRI). Standard karyotype and chromosomal microarray analysis (CMA) were normal. After birth, the newborn presented signs of severe acidosis, untreatable seizures and multiorgan failure leading to death. A targeted gene analysis of the epilepsy panel revealed the presence of a de novo pathogenic variant involving the PTEN gene. The literature review identified four articles reporting on the oCSP of which three were case report and one was a case-series. The reported rate of associated cerebral findings is around 20% and the rate of adverse neurological outcome is around 6%, which is higher than the background risk of the general population. CONCLUSIONS: This case-report and review of the literature shows that oCSP is a clinical entity poorly described so far and that, despite the generally good prognosis, it requires caution in counseling. The diagnostic work-up should include neurosonography while fetal MRI may be always indicated for non-isolated cases only, depending on local facilities. Targeted gene analysis or whole exome sequencing may be indicated for non-isolated cases.

Extrauterine growth restriction in very low birth weight infants according to different growth charts: A retrospective 10 years observational study.

BACKGROUND: Extrauterine growth restriction (EUGR) is common among very low birth weight (VLBW) infants and associated with poor neurodevelopmental outcomes. There are two types of EUGR definitions (cross-sectional and longitudinal) and many growth charts for monitoring postnatal growth. Aims of our study were 1) to compare the rate of small for gestational rate (SGA) and EUGR in a population of VLBW infants, both according to different growth charts (Fenton, INeS charts and Intergrowth-21) and different definitions; 2) to identify risk factors for EUGR. METHODS: This is a single centre retrospective observational study, including all VLBW infants born between January 2009 and December 2018. Anthropometric measures were obtained at birth and at discharge and presented as z-scores according to three growth charts (Fenton, INeS charts, Intergrowth-21). Maternal, clinical and nutritional data were retrieved from clinical records. RESULTS: 228 VLBW were included. Percentage of SGA did not change significantly according to the three different growth charts (Fenton 22.4%, INeS charts 22.8%, Intergrowth 28.2%, p 0.27). Prevalence of EUGR was significantly higher when INeS and Fenton charts were used, compared to Intergrowth charts regardless of EUGR-definition (cross sectional-EUGR: Fenton 33.5%, INeS charts 40.9%, Intergrowth-21 23.8%, p 0.001; longitudinal-EUGR (loss of 1SDS): Fenton 15%, INeS charts 20.4%, Intergrowth 4%, p <0.001). In our population a longer time to reach 100 ml/kg/day of enteral feeding increased of 18% the risk of longitudinal EUGR. Late onset sepsis and retinopathy of prematurity were associated with an increased risk of longitudinal EUGR, although not significantly, while having a preeclamptic mother was associated with a reduced risk. CONCLUSIONS: We confirmed a wide variability of EUGR rates when using different charts and definitions, highlighting that Intergrowth-21 charts identify less EUGR when compared to INeS and Fenton charts. Standardized criteria for defining EUGR are warranted in order to facilitate comparisons between studies and to improve the nutritional management of VLBW infants.

Cortical activation and oxygen perfusion in preterm newborns during kangaroo mother care: A pilot study.

AIM: This study aimed to assess the functional activation of preterm newborns' cerebral cortex during kangaroo mother care. Possible effects of gestational age and previous kangaroo mother care experience were also considered. METHODS: Fifteen preterm newborns were recruited (gestational age: 24-32 weeks). Cortical activation was assessed in frontal, motor and primary somatosensory cortices after 15 and 30 min of kangaroo mother care by multichannel near-infrared spectroscopy (gestational age at assessment: 30-36 weeks). Both oxy- and deoxy-haemoglobin variations were analysed by t-test. Possible effects of gestational age and previous kangaroo mother care experience on cortical activation were studied by regression analysis. RESULTS: After 15 min, bilateral activations (oxy-haemoglobin increase) were observed in frontal, somatosensory and motor cortices. After 30 min, the right motor and primary somatosensory cortices were found activated. Deoxy-haemoglobin increased after 15 min, returning to baseline at 30 min. After 15 min, there was a positive effect of gestational age at the assessment on both haemoglobin concentrations and a negative effect of previous kangaroo mother care on deoxy-haemoglobin increase. CONCLUSION: Motor and somatosensory cortices, particularly on the right side, showed significant activation during kangaroo mother care. Kangaroo mother care seems to benefit activated cortical areas by improving oxygen supply.

Magnetic Resonance Biomarkers and Neurological Outcome of Infants with Mild Hypoxic-Ischaemic Encephalopathy Who Progress to Moderate Hypoxic-Ischaemic Encephalopathy.

BACKGROUND: There is increasing concern that infants with mild hypoxic-ischaemic encephalopathy (HIE) may develop seizures and progress to moderate HIE beyond the therapeutic window for cooling. OBJECTIVE: The aim of this study was to examine the effect of therapeutic hypothermia on magnetic resonance imaging (MRI) biomarkers and neurological outcomes in infants with mild HIE and seizures within 24 h after birth. METHODS: This study shows an observational cohort study on 366 (near)-term infants with mild HIE and normal amplitude-integrated electroencephalography background. RESULTS: Forty-one infants showed progression (11.2%); 29/41 (70.7%) were cooled. Infants with progression showed cerebral metabolite perturbations and higher white matter injury scores compared to those without in both cooled and non-cooled groups (p = 0.001, p = 0.02). Abnormal outcomes were seen in 5/12 (42%) non-cooled and 7/29 (24%) cooled infants with progression (p = 0.26). CONCLUSIONS: Early biomarkers are needed to identify infants with mild HIE at risk of progression. Mild HIE infants with progression showed a higher incidence of brain injury and abnormal outcomes.

Acute drug reaction to phenylephrine and tropicamide collyrium in a late-preterm newborn: a case report.

BACKGROUND: Collyrium administration is a common procedure in the neonatal ward, both in preterm and at term babies. Various molecules are used to induce mydriasis and cycloplegia: among them, phenylephrine and tropicamide are the most popular, and their administration is generally considered safe. CASE PRESENTATION: A 35 + 2 weeks-old, 2510 g, well-appearing male newborn required an ophthalmologic evaluation after a doubtful red reflex test. A collyrium with 1% phenylephrine and 0.95% tropicamide was administered prior to the consult, one drop per eye. Two minutes after the administration, the baby developed a severe apnea that required tactile stimulation. Moreover, the area around his eyes became visibly pale. Three minutes later, the baby became severely bradycardic (59 bpm), but remained in good general condition, so that resuscitation maneuvers were not required. Bradycardia lasted for almost three hours and then gradually resolved. CONCLUSIONS: Cardiopulmonary manifestations, such as bradycardia and even cardiopulmonary arrest, are severe complications that can happen after phenylephrine collyrium administration in preterm newborns. However, they have been described in babies below 1500 g or with concurrent respiratory manifestations. Our patient, on the other hand, was late preterm, and never required a ventilatory support prior to the collyrium administration. Practitioners who deal with premature babies, even if late preterm, must be aware of these possible complications and administer phenylephrine collyrium carefully, where cardiopulmonary resuscitation equipment and personnel are available.

Neonatal presentation of Loeys-Dietz syndrome: two case reports and review of the literature.

BACKGROUND: Loeys-Dietz syndrome (LDS) is a rare connective tissue disorder characterized by cardiovascular manifestations, especially aortic dilatations and arterial tortuosity, craniofacial and skeletal features, joint laxity or contractures, skin abnormalities, hypotonia and motor delay. Its diagnosis is established by the identification of a pathogenic variant in TGFBR1, TGFBR2, SMAD2, SMAD3, TGFB2 or TGFB3 genes. In newborns and toddlers, vascular complications such as aneurism rupture, aortic dissection, and intracerebral incidents, can occur already in the weeks of life. To avoid these events, it is crucial to precociously identify this condition and to start an apunderwent a surgical procedurepropriate treatment which, depending on the severity of the vascular involvement, might be medical or surgical. CASE PRESENTATION: We report two cases of Loeys-Dietz syndrome precociously diagnosed. The first describes a male, born at 38 + 1 weeks of gestation, with hypotonia, joint hypermobility, arachnodactyly, and fingers joint contractures, as well as senile appearance and facial dysmorphisms. In the suspect of a connective tissue disorder, an echocardiography was performed and revealed an aortic root dilatation of 13 mm (Z score + 3). A trio based Whole Exome Sequencing found a novel de novo variant in the TGFBR2 gene. Despite the onset of a low-dose angiotensin receptor blocker therapy, the aneurysm progressed. The second case describes a female, born at 41 + 3 weeks of gestation. During the neonatal examination a cleft palate was noticed, as well as minor dysmorphisms. Since the family history was suspicious for connective tissue disorders, a genetic panel was performed and identified a pathogenetic variant in TGFB3 gene. In this case, the echocardiography revealed no abnormalities. CONCLUSIONS: In addition to our cases, we identified 14 subjects with neonatal LDS in the medical literature. All of them had aortic involvement. Skeletal and face abnormalities, including eyes and palate malformations, were also highly frequent. Overall, 10 subjects required medical therapy to avoid aneurysm progression, and 8 patients underwent surgical procedures. Benefits of an early diagnosis of LDS are various and imply a potential modification of the natural history of the disease with early interventions on its complications.

Empathy at birth: Mother's cortex synchronizes with that of her newborn in pain.

Early neonatal relation with the caregiver is vital for newborn survival and for the promotion of an appropriate neural development. The aim of this study was to assess if the empathic cortical response of a mother to her baby's pain is synchronized with the neonatal cortical response to the painful stimulation. We used hyperscanning, a functional neuroimaging approach that allows studying functional synchronization between two brains. Sixteen mother-newborn dyads were recruited. Maternal and neonatal cortical activities were simultaneously monitored, by near-infrared spectroscopy, during a heel prick performed on the baby and observed by the mother. Multiple paired t test was used to identify cortical activation, and wavelet transform coherence method was used to explore possible synchronization between the maternal and neonatal cortical areas. Activations were observed in mother's parietal cortex, bilaterally, and in newborn's superior motor/somatosensory cortex. The main functional synchronization analysis showed that mother's left parietal cortex activity cross-correlated with that of her newborn's superior motor/somatosensory cortex. Such synchronization dynamically changed throughout assessment, becoming positively cross-correlated only after the leading role in synchronizing cortical activities was taken up by the newborn. Thus, maternal empathic cortical response to baby pain was guided by and synchronized to the newborn's cortical response to pain. We conclude that, in case of potential danger for the infant, brain areas involved in mother-newborn relationship appear to be already co-regulated at birth.

Late-term fetuses with reduced umbilical vein blood flow volume: An under-recognized population at increased risk of growth restriction.

OBJECTIVES: To investigate the umbilical vein and uterine arteries blood flow volume (UV-Q, UtA-Q) in late-term pregnancies. STUDY DESIGN: This was a prospective observational cohort study of singleton pregnancies ≥40 + 0 weeks in which UV-Q and UtA-Q, both absolute and normalized for estimated fetal weight (EFW) values, were evaluated in relation to AC drop of ≥20 percentiles from 20 weeks to term, Doppler signs of fetal cerebral blood flow redistribution and composite adverse perinatal outcome. The presence of neonatal hypoglycaemia and the need of formula milk supplementation were also examined. RESULTS: The study population comprised 200 women. Fetuses with AC drop (n = 34) had a significantly lower UV-Q and UV-Q/EFW than fetuses without AC drop (n = 166): median UV-Q 184 ml/min (IQR 143-225) vs 233 ml/min (IQR 181-277), p = 0.0006; median UV-Q/EFW 55 ml/min/kg (IQR 42-66) vs 63 ml/min/kg (IQR 48-74), p = 0.03. Fetuses with cerebral blood flow redistribution (n = 48) had a significantly lower UV-Q and UV-Q/EFW than those without (n = 134): median UV-Q 210 ml/min (IQR 155-263) vs 236 ml/min (IQR 184-278), p = 0.04; median UV-Q/EFV 58 ml/min/kg (IQR 45-70) vs 65 ml/min/kg (IQR 50-76), p = 0.04. There was a significant moderate correlation between middle cerebral artery pulsatility index (MCA-PI) and UV-Q and UV-Q/EFW (Spearman Rho -0.20 and -0.20; p = 0.008 and p = 0.006). CONCLUSIONS: The umbilical vein blood flow volume might have a potential role to identify fetuses with stunted growth in late-term pregnancies.

Problem-based learning for in-service training on breastfeeding in Friuli Venezia Giulia, Italy.

BACKGROUND: Problem-Based Learning (PBL) is extensively used in pre- and post-graduate teaching programmes. However, it has been seldom used for in-service training and continuing medical education. We aimed to develop a PBL curriculum for a short in-service training on breastfeeding for maternal and child health professionals, and to assess the effect of these courses on their knowledge and skills. Also, the project aimed at increasing exclusive breastfeeding rates and duration in an Italian region. METHODS: After initial training on PBL and an assessment of the learning needs of about 400 health professionals, a small working group developed learning objectives, designed a curriculum, produced manuals, and shaped assessment tools for a new PBL course on breastfeeding. The field test of the new course allowed selection of the tutors for the scaling up of the training to the whole region. During this extension phase, participants were asked to complete an evaluation questionnaire. In addition, the health professionals who attended the PBL courses in 2019 were asked to complete an online survey to assess knowledge, attitudes and practices (KAP) just before, soon after the course, and 4-6 months later. RESULTS: The new 29 - hour PBL course, to be delivered in four days over four consecutive weeks, gives priority to tutorial groups and practical activities (71% of the total time). Supervised clinical practices absorb 16% of time. Ethics, communication and woman-centred clinical management content run throughout the four days and all activities. The three manuals, for tutors, participants and practical activities, facilitate the tasks and performance of tutors and participants. After the field test, 32 regional tutors ran courses for 562 health professionals. The analysis of the evaluation showed a high level of satisfaction for perceived effectiveness, relevance to practice, and educational quality. The KAP questionnaires indicated a general improvement after the course and retention after 4-6 months. CONCLUSIONS: Despite some predictable shortcomings, this new PBL approach for short in-service training courses on breastfeeding showed encouraging results as far as participants' satisfaction and KAP are concerned. The possible effects on rates and duration of exclusive breastfeeding need further research.

Parental Stress, Depression, and Participation in Care Before and During the COVID-19 Pandemic: A Prospective Observational Study in an Italian Neonatal Intensive Care Unit.

Background: Recent studies reported, during the COVID-19 pandemic, increased mental distress among the general population and among women around the childbirth period. COVID-19 pandemic may undermine the vulnerable well-being of parents in Neonatal Intensive Care Units (NICUs). Objective: Our study aimed to explore whether parental stress, depression, and participation in care in an Italian NICU changed significantly over three periods: pre-pandemic (T0), low (T1), and high COVID-19 incidence (T2). Methods: Enrolled parents were assessed with the Parental Stressor Scale in the NICU (PSS:NICU), Edinburgh Postnatal Depression Scale (EPDS), and Index of Parental Participation (IPP). Stress was the study primary outcome. A sample of 108 parents, 34 for each time period, was estimated to be adequate to detect a difference in PSS:NICU stress occurrence level score (SOL) of 1.25 points between time periods. To estimate score differences among the three study periods a non-parametric analysis was performed. Correlation among scores was assessed with Spearman rank coefficient. Results: Overall, 152 parents were included in the study (62 in T0, 56 in T1, and 34 in T2). No significant differences in the median PSS:NICU, EPDS, and IPP scores were observed over the three periods, except for a slight increase in the PSS:NICU parental role sub-score in T2 (T0 3.3 [2.3-4.1] vs. T2 3.9 [3.1-4.3]; p = 0.038). In particular, the question regarding the separation from the infant resulted the most stressful aspect during T2 (T0 4.0 [4.0-5.0] vs. T2 5.0 [4.0-5.0], p = 0.008). The correlation between participation and stress scores (r = 0.19-022), and between participation and depression scores (r = 0.27) were weak, while among depression and stress, a moderate positive correlation was found (r = 0.45-0.48). Conclusions: This study suggests that parental stress and depression may be contained during the COVID-19 pandemic, while participation may be ensured.
