Being a mother of preterm multiples in the context of socioeconomic disadvantage: perceived stress and psychological symptoms / Ser mãe de múltiplos prematuros no contexto de desvantagem socioeconômica: estresse percebido e sintomas psicológicos

Abstract Objective: This study aimed to examine the differences between mothers of preterm multiples and mothers of preterm singletons regarding perceived stress and maternal psychological symptoms, and to explore the putative adverse amplified effect of socioeconomic disadvantage. Method: Ninety-five mothers of 1-year-olds born preterm participated in this cross-sectional study. Data collection was carried out in two public hospitals from Northern Portugal. To assess maternal perceived daily stress and psychological symptoms, mothers completed two questionnaires. Mothers reported on socioeconomic factors, including family poverty, parent unemployment, and low education, and two groups of family socioeconomic disadvantage were created. A child medical risk index was calculated. Results: Results indicated that mothers of preterm multiples reported higher levels of stress than mothers of preterm singletons. Moreover, and specifically regarding psychological functioning, mothers of preterm multiples reported more symptoms than mothers of preterm singletons, but only when living in a context of socioeconomic adversity. Conclusions: The results of the present study have important implications for practice. Mothers of preterm multiples are at higher risk to present mental health difficulties, in comparison to mothers of singletons, especially when exposed to socioeconomic adversities. The development of psychosocial intervention programs and public policies are of decisive importance in helping mothers of multiples adjust to parenthood.

Resumo Objetivo: Examinar as diferenças entre mães de múltiplos prematuros e mães de filhos únicos prematuros a respeito de estresse percebido e sintomas psicológicos maternos e explorar o efeito adverso amplificado putativo da desvantagem socioeconômica. Método: Participaram deste estudo transversal 95 mães de crianças de um ano nascidas prematuras. A coleta de dados foi feita em dois hospitais públicos do norte de Portugal. Para avaliar o estresse diário percebido e os sintomas psicológicos maternos, as mães responderam dois questionários. As mães relataram fatores socioeconômicos, incluindo pobreza familiar, desemprego dos pais e baixo nível de escolaridade, e foram criados dois grupos de desvantagem socioeconômica familiar. Foi calculado um índice de risco médico infantil. Resultados: Os resultados indicaram que as mães de múltiplos prematuros relataram maiores níveis de estresse do que as mães de filhos únicos prematuros. Além disso e especificamente com relação ao funcionamento psicológico, as mães de múltiplos prematuros relataram mais sintomas do que as mães de filhos únicos prematuros, porém apenas quando moravam em um contexto de adversidade socioeconômica. Conclusões: Os resultados deste estudo possuem importantes implicações para a prática. As mães de múltiplos prematuros apresentam maior risco de dificuldades de saúde mental, em comparação a mães de filhos únicos, principalmente quando expostas a adversidades socioeconômicas. O desenvolvimento de programas de intervenção psicossocial e políticas públicas é de importância decisiva ao ajudar as mães de filhos múltiplos a se ajustarem à maternidade.

Caries in Portuguese children with Down syndrome

OBJECTIVES: Oral health in Down syndrome children has some peculiar aspects that must be considered in the follow-up of these patients. This study focuses on characterizing the environmental and host factors associated with dental caries in Portuguese children with and without Down syndrome. METHODS: A sibling-matched, population-based, cross-sectional survey was performed. RESULTS: Down syndrome children presented a significantly greater percentage of children without caries, 78 percent vs. 58 percent of non-Down syndrome siblings. This difference in the DMFT index (number of decayed, missing and filled teeth) essentially reflects data obtained from treated teeth, for which 91 percent of children with Down syndrome had never had a tooth treated vs. 67 percent of siblings. This result was statistically significant, whereas results for decayed and lost teeth did not differ between Down syndrome children and their unaffected siblings. Additionally, in Down syndrome children, a delayed eruption of the second molar occurs. Down syndrome children and their siblings have similar oral hygiene habits, but a higher percentage of Down syndrome children visit a dentist before the age of three years, in comparison to their siblings. Bruxism was also more common in Down syndrome children compared to their siblings. CONCLUSIONS: Our results show that Portuguese children with Down syndrome have lower caries rates than children without Down syndrome. This reduced prevalence may be associated with the parents' greater concern about oral health care in Down syndrome children, resulting in their taking them sooner to visit a dentist, as well as to a higher bruxism prevalence and delayed tooth eruption.

Respiratory outcomes and atopy in school-age children who were preterm at birth, with and without bronchopulmonary dysplasia

OBJECTIVE: To assess pulmonary function and the prevalence of atopy in school-age children who were very low birth weight as infants and to compare those who had bronchopulmonary dysplasia to those who did not. METHOD: We studied 85 (39 male and 46 female) at a mean age of 84 (range, 62 to 107) months who were very low birth weight infants. Bronchopulmonary dysplasia was defined as oxygen dependency at 36 weeks gestational age. We excluded 8 patients (4 for cerebral palsy and 4 for no collaboration). Detailed perinatal and clinical data were collected. Lung function was evaluated using conventional spirometry. Atopy (assessed by the allergy skin-prick test) was considered when at least one positive skin test occurred in a panel of the most common environmental allergens in the local region. Comparisons between the bronchopulmonary dysplasia and no bronchopulmonary dysplasia groups were performed using the Mann-Whitney, x2 and Fisher's exact tests. RESULTS: We compared the bronchopulmonary dysplasia (n = 13) and no bronchopulmonary dysplasia (n = 64) groups. Atopy was observed in 4 (30.8 percent) of the bronchopulmonary dysplasia patients and in 17 (26.6 percent) of the no bronchopulmonary dysplasia patients (p = 0.742). Two (15.4 percent) patients with bronchopulmonary dysplasia had a family history of atopy vs. 17 (26.6 percent) in the no bronchopulmonary dysplasia group (p = 0.5). Lung function tests showed airway obstruction in 2 (15.4 percent) of the bronchopulmonary dysplasia patients and in 10 (15.6 percent) of the no bronchopulmonary dysplasia patients (p = 1.0). Four (33.3 percent) of the bronchopulmonary dysplasia patients had small airway obstruction vs. 14 (22.2 percent) of the no bronchopulmonary dysplasia patients (p = 0.466). CONCLUSION: Our data showed no significant differences in lung function between bronchopulmonary dysplasia and no bronchopulmonary dysplasia patients at school age and no evidence of an association between atopy and bronchopulmonary dysplasia.

End of life in the neonatal intensive care unit

PURPOSE: Death at the beginning of life is tragic but not uncommon in neonatal intensive care units. In Portugal, few studies have examined the circumstances surrounding the final moments of neonates. We evaluated the care given to neonates and their families in terminal situations and the changes that had occurred one decade later. DESIGN AND METHODS: We analyzed 256 charts in a retrospective chart review of neonatal deaths between two periods (1992-1995 and 2002-2005) in a level III neonatal intensive care unit. RESULTS: Our results show differences in the care of dying infants between the two periods. The analysis of the 2002-2005 cohort four years revealed more withholding and withdrawing of therapeutic activities and more effective pain and distress relief; however, on the final day of life, 95.7 percent of the infants received invasive ventilatory support, 76.3 percent received antibiotics, 58.1 percent received inotropics, and 25.8 percent received no opioid or sedative administration. The 2002-2005 cohort had more spiritual advisor solicitation, a higher number of relatives with permission to freely visit and more clinical meetings with neonatologists. Interventions by parents, healthcare providers and ethics committees during decision-making were not documented in any of the charts. Only eight written orders regarding therapeutic limitations and the adoption of palliative care were documented; seven (87.5 percent) were from the 2002-2005 cohort. Parental presence during death was more frequent in the latter four years (2002-2005 cohort), but only 21.5 percent of the parents wanted to be present at that moment. CONCLUSION: Despite an increase in the withholding and withdrawing of therapeutic activities and improvements in pain management and family support, many neonates still receive curative and aggressive practices at the end of life.

Gastroschisis: preterm or term delivery?

AIM: The main objective of this study was to evaluate the association between prematurity and the time to achieve full enteral feeding in newborns with gastroschisis. The second objective was to analyze the associations between length of hospital stay and time to achieve full enteral feeding with mode of delivery, birth weight and surgical procedure. METHODS: The medical records of newborns with gastroschisis treated between 1997 and 2007 were reviewed. Two groups were considered: those delivered before 37 weeks (group A) and those delivered after 37 weeks (group B). The variables of gestational age, mode of delivery, birth weight, time to achieve full enteral feeding, length of hospital stay and surgical approach were analyzed and compared between groups. RESULTS: Forty-one patients were studied. In Group A, there were 14 patients with a mean birth weight (BW) of 2300 g (range=1680-3000) and a mean gestational age (GA) of 36 weeks (range=34-36). In group B, there were 24 patients with a mean BW of 2700 g (range=1500-3550) and a mean GA of 38 weeks (range=37-39). The mean time to achieve full enteral feeding was 30.1±6.7 days in group A and 17.0±2.5 days in group B (p=0.09) with an OR of 0.82 and a 95 percent CI of 0.20-3.23 after adjustment for sepsis and BW. No statistical difference was found between low BW (<2500 g), mode of delivery and number of days to achieve full enteral feeding (p=0.34 and p=0.13, respectively). Patients with BW over 2500 g had fewer days in the hospital (22.9±3.1 vs. 35.7±5.7 days; p=0.06). CONCLUSION: The results of this study do not support the idea of anticipating the delivery of fetuses with gastroschisis in order to achieve full enteral feeding earlier.

Fluid and electrolyte balance during the first week of life and risk of bronchopulmonary dysplasia in the preterm neonate

BACKGROUND: Early fluid and electrolyte imbalances may be associated with an increased risk of bronchopulmonary dysplasia. OBJECTIVE: We sought to establish an association between fluid and electrolyte balance in the first week of life and the risk of bronchopulmonary dysplasia. METHODS: Clinical charts of 205 neonates <32 weeks gestational age and/or <1,250 g birth weight (admitted to our NICU between 1997 and 2008) were analyzed. Clinical features, fluid and electrolyte balance were analyzed for the first 7 days of life using multivariate models of generalized estimation equations. A p value <0.05 was considered significant in all of the hypothesis tests. RESULTS: The prevalence of bronchopulmonary dysplasia was 22 percent. Lower gestational age and birth weight, male gender, less frequent use of antenatal steroids, respiratory distress syndrome, use of surfactant, patent ductus arteriosus, duration of invasive ventilation and NICU stay were significantly associated with bronchopulmonary dysplasia. The variation in serum values of potassium, phosphorus and creatinine during the first week of life also revealed an association with bronchopulmonary dysplasia. Higher mean plasma calcium values were associated with spontaneous closure of the patent ductus arteriosus. The use of indomethacin to induce patent ductus arteriosus closure was significantly higher in bronchopulmonary dysplasia patients. CONCLUSIONS: Differences in renal function and tubular handling of potassium and phosphorus are present during the first week of life among preterm neonates who will develop bronchopulmonary dysplasia. The higher rate of patent ductus arteriosus and indomethacin use may influence these differences. Serum levels of calcium also appear to play a role in spontaneous ductus arteriosus closure.
