The COVID-related mental health load of neonatal healthcare professionals: a multicenter study in Italy.

BACKGROUND: The COVID-19 pandemic has dramatically affected healthcare professionals' lives. We investigated the potential mental health risk faced by healthcare professionals working in neonatal units in a multicentre cross-sectional observational study. METHODS: We included all healthcare personnel of seven level-3 and six level-2 neonatal units in Tuscany, Italy. We measured the level of physical exposure to COVID-19 risk, self-reported pandemic-related stress, and mental health load outcomes (anxiety, depression, burnout, psychosomatic symptoms, and post-traumatic symptoms) using validated, self-administered, online questionnaires during the second pandemic wave in Italy (October 2020 to March 2021). RESULTS: We analyzed 314 complete answers. Scores above the clinical cutoff were reported by 91% of participants for symptoms of anxiety, 29% for post-traumatic symptoms, 13% for burnout, and 3% for symptoms of depression. Moreover, 50% of the participants reported at least one psychosomatic symptom. Pandemic-related stress was significantly associated with all the measured mental health load outcomes, with an Odds Ratio of 3.31 (95% confidence interval: 1.87, 5.88) for clinically relevant anxiety, 2.46 (1.73, 3.49) for post-traumatic symptoms, 1.80 (1.17, 2.79) for emotional exhaustion, and 2.75 (1.05, 7.19) for depression. Female health care professionals displayed a greater risk of anxiety, and male health care professionals and nurses, of depressive symptoms. CONCLUSIONS: Despite the low direct clinical impact of COVID-19 in newborns, neonatal professionals, due to both living in a situation of uncertainty and personal exposure to contacts with parents and other relatives of the newborns, and having to carry out activities once routine and now fraught with uncertainty, displayed clear signs of mental health load outcomes. They must be considered a specific population at risk for psychological consequences during the pandemic.

A machine learning approach to estimating preterm infants survival: development of the Preterm Infants Survival Assessment (PISA) predictor.

Estimation of mortality risk of very preterm neonates is carried out in clinical and research settings. We aimed at elaborating a prediction tool using machine learning methods. We developed models on a cohort of 23747 neonates <30 weeks gestational age, or <1501 g birth weight, enrolled in the Italian Neonatal Network in 2008-2014 (development set), using 12 easily collected perinatal variables. We used a cohort from 2015-2016 (N = 5810) as a test set. Among several machine learning methods we chose artificial Neural Networks (NN). The resulting predictor was compared with logistic regression models. In the test cohort, NN had a slightly better discrimination than logistic regression (P < 0.002). The differences were greater in subgroups of neonates (at various gestational age or birth weight intervals, singletons). Using a cutoff of death probability of 0.5, logistic regression misclassified 67/5810 neonates (1.2 percent) more than NN. In conclusion our study - the largest published so far - shows that even in this very simplified scenario, using only limited information available up to 5 minutes after birth, a NN approach had a small but significant advantage over current approaches. The software implementing the predictor is made freely available to the community.

Chest physiotherapy with positive airway pressure: a pilot study of short-term effects on sputum clearance in patients with cystic fibrosis and severe airway obstruction.

BACKGROUND: The periodic administration of positive airway pressure combined with directed cough could aid mucus clearance in patients with cystic fibrosis (CF) and severe airway obstruction. OBJECTIVE: To compare the short-term effect of positive expiratory pressure (PEP) physiotherapy via mask (mask PEP), continuous positive airway pressure (CPAP), and noninvasive positive-pressure ventilation (NPPV) physiotherapies on amount of sputum collected. METHODS: Directed cough was standardized for each patient and used as the control treatment. We studied 17 patients with CF (mean +/- SD age 28 +/- 7 y) and severe airway obstruction (forced expiratory volume in the first second 25 +/- 6% of predicted) admitted for pulmonary exacerbation. Mask PEP, CPAP, NPPV, and the control treatment (directed cough) were administered in a random sequence. Each patient received each treatment twice a day (in 70-min sessions) for 2 consecutive days. We measured the wet and dry weight of sputum collected and the number of directed and spontaneous coughs during each session. Spirometry and pulse oximetry were conducted before and after each session. For mask PEP, CPAP, and NPPV, each patient gave a subjective score for the efficacy and tolerability of the treatment, compared to the control treatment. RESULTS: There was no statistically significant difference in the dry weight of sputum collected: mask PEP 0.9 +/- 0.6 g, CPAP 0.8 +/- 0.4 g, NPPV 0.9 +/- 0.6 g, control treatment 1.0 +/- 0.8 g. There was a statistically significant difference in the wet weight of sputum collected: mask PEP 15.8 +/- 5.5 g, CPAP 13.7 +/- 5.5 g, NPPV 13.2 +/- 5.0 g, control treatment 14.0 +/- 5.0 g (p < 0.05), but that difference became nonsignificant when we took into account the number of spontaneous coughs. There were no statistically significant changes in the spirometry and pulse-oximetry values. The patients' subjective efficacy scores were similar for mask PEP, CPAP, and NPPV. Less fatigue was reported after NPPV and CPAP than after mask PEP. CONCLUSIONS: There were no differences in sputum clearance or pulmonary-function measures between mask PEP and short-term administration of either CPAP or NPPV combined with directed cough. After mask PEP these patients felt more tired than after CPAP or NPPV secretion-clearance therapy.

Prolactin secretion before, during, and after chronic gonadotropin-releasing hormone agonist treatments in children.

OBJECTIVE: To examine the effect of long-term administration of GnRH agonists (GnRHa) on PRL secretion in children affected by central precocious puberty (CPP) and growth hormone deficiency (GHD). DESIGN: Prospective analysis of blood sampling before, during, and after GnRHa treatments. SETTING: Pediatric endocrine center. PATIENT(S): One hundred nineteen and 93 children with a diagnosis of CPP and GHD, respectively. INTERVENTION(S): Monthly depot injections of GnRHa drugs (leuprorelin acetate 3.75 mg [LA] and triptorelin 3.75 mg [TR]) administered to CPP and GHD patients for 40 and 24 months, respectively. MAIN OUTCOME MEASURE(S): Serum PRL levels at baseline and after 6, 12, 18, 24, 30, 36, and 40 months of treatment with GnRHa were compared between CPP and GHD groups. PRL levels at 6 and 12 months after GnRHa withdrawal were also examined. RESULT(S): Although serum PRL levels tended to be higher in TR- than in LA-treated patients, no significant difference in circulating PRL in basal condition and during GnRHa treatment was detected between the CPP and GHD groups. However, five children (3.8%) developed hyperprolactinemia during TR treatment. CONCLUSION(S): Although there are no general concerns about GnRHa treatment safety, careful PRL monitoring is required in GnRHa-treated children.
