Effect of Donated Premature Milk in the Prevention of Bronchopulmonary Dysplasia.

INTRODUCTION: Breastfeeding is one of the strategies that has been shown to be effective in preventing severe forms of bronchopulmonary dysplasia (BPD). When mother's own milk (MOM) is not available, pasteurized donor milk (DM) is the best alternative. However, the evidence is inconclusive on the difference in the incidence of bronchopulmonary dysplasia (BPD) between patients fed MOM and those fed with DM. As standard DM is usually mature pooled milk donated by mothers who have delivered their babies at term, the potential benefits of preterm milk may be lost. MATERIALS AND METHODS: An observational, retrospective, single-center study was conducted in the neonatology department of a high-complexity hospital. The study included newborns <32 weeks of gestational age born between January 2020 and December 2022. When supplemental milk was needed, non-pooled preterm pasteurized donor milk (PDM) matched for gestational age and moment of lactation was used in this study, classifying preterm infants in two groups: mainly MOM (>50% of the milk) or mainly PDM (>50% of the milk). Two groups were established: those who received >50% MOM and those who received >50% PDM. They were also classified according to the diagnosis of DBP: one group included no BPD or grade 1 BPD (noBPD/1), while the other included grade 2 or 3 BPD (BPD 2-3). The objectives of this study were, firstly, to evaluate the incidence of BPD 2-3 among patients who predominantly received PDM versus MOM. Secondly, to analyze differences in the type of human milk received and its nutritional components, as well as to study the growth in patients with or without BPD. RESULTS: One hundred ninety-nine patients were included in the study. A comparison of noBPD/1 versus BPD 2-3 groups between those receiving mainly MOM versus PDM showed no significant differences (19% vs. 20%, p 0.95). PDM colostrum in BPD 2-3 compared to noBPD/1 was higher in protein content (2.24 g/100 mL (SD 0.37) vs. 2.02 g/100 mL (SD 0.29) p < 0.01), although the statistical significance decreased after adjustment for gestational age and birth weight z-score (OR 3.53 (0.86-14.51)). No differences were found in the macronutrients in the mature milk of patients feeding more than 50% PDM in both study groups. Growth of BPD 2-3 showed a greater decrease in the difference in z-scores for height at birth and at discharge compared to noBPD/1 (-1.64 vs. -0.43, p 0.03). CONCLUSIONS: The use of mainly MOM or PDM demonstrates a similar incidence of noBPD/1 or BPD 2-3. Non-pooled and matched by gestational age and time of lactation preterm donor milk can probably be an alternative when mother's own milk is not available, with a similar protective effect in the prevention of severe BPD.

[The impact of SARS-CoV-2 pandemic on patients who attend a pediatric emergency department for mental health issues]. / Impacto de la pandemia por SARS-CoV-2 en los pacientes que acuden a urgencias de pediatría por problemas de salud mental.

The lockdown during the SARS-CoV-2 pandemic and the effect of the virus on the population could be a precipitating factor for mental health disorders in the pediatric population. OBJECTIVE: To compare the reasons for consultation, diagnoses at discharge, and admission and re-consultation rates of pediatric patients attending the Emergency Department due to mental health disorders before and after the SARS-CoV-2 pandemic lockdown. PATIENTS AND METHOD: Retrospective, descriptive study. Patients under 16 years of age consulting due to mental health-related disorders during the pre- (07/01/2018-07/01/2019) and post-lockdown (07/01/2020-07/01/2021) periods were included. The frequency of mental health diagnoses, need for drug administration, hospitalization, and reconsultations were compared. RESULTS: 760 patients were included, 399 pre-lockdown and 361 postlockdown. After the lockdown, there was a 45.7% increase in the frequency of mental health-related consultations with respect to the total number of emergency consultations. Behavioral alterations were the most frequent reason for consultation in both groups (34.3% vs. 36.6%, p = 0.54). In the post-lockdown period, consultations related to self-harm attempts (16.3% vs. 24.4%, p < 0.01) and the diagnosis of depression (7.5% vs. 18.5%, p < 0.01) increased significantly. There was an increase of 58.8% in patients who were hospitalized with respect to the total number of ED patients (0.17% vs. 0.27%, p = 0.003) and in the number of re-consultations (12% vs. 17.8%, p = 0.026). No differences were observed in days of hospitalization (7 days [IQR 4-13] vs. 9 days [IQR 9-14], p0.45). CONCLUSION: In the post-lockdown period, the proportion of pediatric patients presenting to the ED with mental health disturbances increased.

Long-term anticoagulant treatment in patients with inferior vena cava agenesis and deep vein thrombosis.

INTRODUCTION: Inferior vena cava agenesis (IVCA) is a rare and underdiagnosed congenital anomaly that predisposes to deep vein thrombosis (DVT). Optimal duration of anticoagulant treatment in these patients is not well established. METHOD: Observational retrospective study that included all consecutive patients older than 18 diagnosed with IVCA and DVT. Data including demographics, initial clinical presentation, modality of diagnosis, treatment and outcomes were obtained. RESULTS: In patients with IVCA and DVT (n = 9), mean age was 42 and 66% were males. Five (55,5%) patients had bilateral DVT and the most frequent location was ilio-femoral. Only one patient had concomitant pulmonary embolism (PE). During follow-up (mean of 77.8 months), anticoagulation was withdrawn in 2 patients and both developed recurrence of DVT (22.2%, CI 95% 2.8-60.0). One minor bleeding (11.1%, CI 95% 0.3-48.3), five post-thrombotic syndrome (55.6%, CI 95% 21.2-86.3) and no deaths were registered. CONCLUSION: In patients with DVT and IVCA, post-thrombotic syndrome was developed in approximately half of the patients. No major bleeding events were recorded during long-term anticoagulant therapy and recurrences occurred only in patients who had anticoagulation withdrawn. These data suggest that extended anticoagulant therapy might be considered in these patients.
