Maternal health care professionals perspective on the provision and use of antenatal and delivery care : a qualitative descriptive study in rural Vietnam

Background. High quality maternal health care is an important tool to reduce maternal and neonatal mortality. Services offered should be evidence based and adapted to the local setting. This qualitative descriptive study explored the perspectives and experiences of midwives, assistant physicians and medical doctors on the content and quality of maternal health care in rural Vietnam. Method. The study was performed in a rural district in northern Vietnam. Four focus group discussions with health care professionals at primary health care level were conducted. The data was analysed using qualitative manifest and latent content analysis. Result. Two main themes emerged: "Contextual conditions for maternal health care" and "Balancing between possibilities and constraints". Contextual conditions influenced both pregnant women's use of maternal health care and health care professionals' performance. The study participants stated that women's uses of maternal health care were influenced by economical constraints and cultural norms that impeded their autonomy in relation to childbearing. Structural constraints within the health care system included inadequate financing of the primary health care, resulting in lack of human resources, professional re-training and adequate equipment. Conclusion. Contextual conditions strongly influenced the performance and interaction between pregnant women and health care professionals within antenatal care and delivery care in a rural district of Vietnam. Although Vietnam is performing comparatively well in terms of low maternal and child mortality figures, this study revealed midwives' and other health care professionals' perceived difficulties in their daily work. It seemed maternal health care was under-resourced in terms of staff, equipment and continuing education activities. The cultural setting in Vietnam constituting a strong patriarchal society and prevailing Confucian norms limits women's autonomy and reduce their possibility to make independent decisions about their own reproductive health. This issue should be further addressed by policy-makers. Strategies to reduce inequities in maternal health care for pregnant women are needed. The quality of client-provider interaction and management of pregnancy may be strengthened by education, human resources, re-training and provision of essential equipment.

Blood galactose and glucose levels in mothers, cord blood, and 48-hour-old breast-fed full-term infants

Background: Although galactose is an important component in human lactose, there are few reports of its role in the newborn metabolism. Objective: To determine the relationship of blood galactose and glucose levels in mothers, cord blood, and breast-fed full-term newborn infants. Methods: Maternal and cord vein blood samples were obtained from 27 pregnant women at delivery, and from their breastfed, full-term newborns 48 h later. Galactose and glucose were determined by HPLC. Statistical analysis used ANOVA and Pearson correlation with p < 0.05. Results: Maternal galactose concentrations (0.08 +/- 0.03 mmol/l) were similar to cord blood galactose (0.07 +/- 0.03 mmol/l; p = 0.129). However, newborn blood galactose (0.05 +/- 0.02 mmol/l) was significantly lower than both cord (p = 0.042) and maternal blood (p = 0.002). Maternal blood glucose levels (4.72 +/- 0.86 mmol/l) were higher than cord blood (3.98 +/- 0.57 mmol/l; p < 0.001), and cord blood concentrations were higher than newborn blood levels (3.00 +/- 0.56 mmol/l; p < 0.001); all values expressed as mean +/- SD. Significant correlation was only seen between maternal and cord blood galactose levels (r = 0.67; p < 0.001) and glucose levels (r = 0.38; p = 0.047). Conclusion: the association and similarity between maternal and cord blood galactose levels suggest that the fetus is dependent on maternal galactose. In contrast, the lower galactose levels in newborn infants and a lack of association between both suggest self-regulation and a dependence on galactose ingestion. Copyright (c) 2007 S.

Fetal and maternal lesions of cyanide dosing to pregnant goats

The present work evaluated the pathological effects in both dams and their fetuses of cyanide ingestion during pregnancy using goat as animal model. From the Day 24 of pregnancy, three pregnant goats were dosed by gavage with 3.0 mg KCN/kg bw/day, and two others received only tap water. All dams were euthanized and necropsied at Day 120 of pregnancy. The fetuses were examined carefully for gross abnormalities. Determinations of cyanide and thiocyanate were performed in maternal and fetal blood and in amniotic fluid. Samples of several organs were collected for histopathologic evaluation. No clinical changes were seen in any animal throughout the pregnancy. No malformations or dead fetuses were observed: however, placenta from one treated goat presented increased cotyledon surface area occupied by vascular lumina. Histological lesions in KCN-treated dams consisted of vacuolation of hepatocytes and thyroid follicular cells, increased number of vacuoles on thyroid follicular colloid. and spongiosis of cerebral, internal capsule, and cerebellar peduncles tracts. Fetuses from these mothers showed vacuolation of hepatocytes and thyroid follicular cells, and spheroids in the cerebellar white matter. Levels of cyanide and thiocyanate were higher in maternal than fetal blood, which suggests that these substances were largely but not freely transferred from mothers to fetuses.

Melatonin effects on macrophage in diabetic rats and the maternal hyperglycemic implications for newborn rats

The modulatory effects of melatonin (MLT) on maternal and fetal macrophages in diabetic rats and the repercussion of maternal hyperglycemia on fetus-placenta parameters were studied. This was achieved by determining maternal and fetal blood glucose, weight and superoxide release by macrophages. Placental weight, protein, DNA and RNA concentration were also verified. Superoxide levels in macrophages isolated from pregnant healthy rats were higher than those obtained from diabetic animals. Melatonin increased significantly in the macrophages of control animals (18.7 ± 2.8 with MLT compared to 14.2 ± 1.6 without MLT) but decreased with melatonin stimulation in diabetic rats (8.8 ± 1.4 with MLT compared to 12.9 ± 2.1 without MLT). Melatonin significantly decreased superoxide levels in newborns of diabetic mothers (7.3 ± 3.4) compared to those of healthy (14.6 ± 3.5) mothers. Blood glucose levels were significantly higher (p<0.05) in newborn rats of diabetic mothers (108.3 ± 7.8) compared to blood glucose levels in newborn control rats (81.2 ± 10.7). Body weight was significantly higher (p <0.05) in the offspring of rats with alloxan-induced diabetes. No statistical difference (p> 0.05) was observed in the placenta weight, total protein concentration and DNA of rats. The RNA concentration was significantly lower (p <0.05) in the placentas of rats with alloxan-induced diabetes (156.1 ± 71.8), when compared to the concentration of RNA in the placentas of control rats (239.5 ± 77.3). In conclusion, maternal hyperglycemia modified the fetus-placental parameters and melatonin modulated the macrophages activation in maternal and fetal diabetic rats.

Effect of ambulatory versus hospital treatment for gestational diabetes or hyperglycemia on infant mortality rates: a systematic review

CONTEXTO E OBJETIVO:Gestações complicadas pelo diabetes estão associadas com aumento das complicações neonatais e maternas. A complicação mais grave materna é o risco de desenvolver diabetes tipo 2 após 10-12 anos do parto. Para o controle rigoroso da glicose no sangue, as mulheres grávidas são tratadas de forma ambulatorial ou com internações hospitalares. O objetivo deste estudo é avaliar a efetividade do tratamento ambulatorial versus hospitalização em gestações complicadas por diabetes ou hiperglicemia.TIPO DE ESTUDO E LOCAL:Revisão sistemática conduzida em hospital universitário público.MÉTODOS:Uma revisão sistemática da literatura foi realizada e as principais bases de dados eletrônicas foram pesquisadas. A data da pesquisa mais recente foi 4 de setembro de 2011. Dois autores selecionaram independentemente os ensaios clínicos relevantes, avaliaram a qualidade metodológica e extraíram os dados.RESULTADOS:Apenas três estudos foram selecionados, com tamanho de amostra pequeno. Não houve diferença estatisticamente significativa entre o tratamento ambulatorial versus hospitalização em relação à mortalidade em nenhuma das subcategorias analisadas: mortes perinatais e neonatais, (risco relativo [RR] 0,65; 95% de intervalo de confiança [IC] 0,11-3,84, P = 0,63); morte neonatal (RR 0,29, IC 95% 0,01-6,07, P = 0,43), e óbitos infantis (RR 0,29, IC 95% 0,01-6,07, P = 0,43).CONCLUSÕES:Com base em estudos com risco de viés alto ou moderado, esta revisão demonstrou que não há diferença estatisticamente significante entre o tratamento ambulatorial comparado com o hospitalar na redução das taxas de mortalidade em gestações complicadas por diabetes ou hiperglicemia. Esta revisão sistemática também sugere a necessidade de mais ensaios clínicos randomizados sobre o assunto.

Toxic heritage: maternal transfer of pyrethroid insecticides and sunscreen agents in dolphins from Brazil

Pyrethroids (PYR) and UV filters (UVF) were investigated in tissues of paired mother-fetus dolphins from Brazilian coast in order to investigate the possibility of maternal transfer of these emerging contaminants. Comparison of PYR and UVF concentrations in maternal and fetal blubber revealed Franciscana transferred efficiently both contaminants to fetuses (F/M > 1) and Guiana dolphin transferred efficiently PYR to fetuses (F/M > 1) different than UVF (F/M < 1). PYR and UVF concentrations in fetuses were the highest-ever reported in biota (up to 6640 and 11,530 ng/g lw, respectively). Muscle was the organ with the highest PYR and UVF concentrations (p < 0.001), suggesting that these two classes of emerging contaminants may have more affinity for proteins than for lipids. The high PYR and UVF concentrations found in fetuses demonstrate these compounds are efficiently transferred through placenta. This study is the first to report maternal transfer of pyrethroids and UV filters in marine mammals.

Fluoride concentrations of milk, infant formulae, and soy-based products commercially available in Brazil

To assess the fluoride (F) content in commercially available milk formulae in Brazil and to estimate the F intake in children from this source in the first year of life. Samples of cow's milk (n = 51), infant formulae (n = 15), powdered milk (n = 13), and soy-based products (n = 4) purchased in Araçatuba (Brazil) had their F content measured using an ion-specific electrode, after hexamethyldisiloxane-facilitated diffusion. Powdered milk and infant formulae were reconstituted with deionized water, while ready-to-drink products were analyzed without any dilution. Using average infant body masses and suggested volumes of formula consumption for infants 1-12 months of age, possible F ingestion per body mass was estimated. Data were analyzed by descriptive analysis. Mean F content ranged from 0.02 to 2.52 mg/L in all samples. None of the cow's milk provided F intake higher than 0.07 mg/kg. However, two infant formulae, one powdered milk, and one soy-milk led to a daily F intake above the suggested threshold for fluorosis when reconstituted with deionized water. Assuming reconstitution of products with tap water at 0.7 ppm F, two infant formulae, five powdered milk, and four soymilks led to daily F intake ranging from 0.108 to 0.851 mg/kg. The results suggest that the consumption of some brands of infant formulae, powdered milk, and soy-based milk in the first year of age could increase the risk of dental fluorosis, reinforcing the need for periodic surveillance of the F content of foods and beverages typically consumed by young children.

Maternal smoking during pregnancy and primary headache in school-aged children: a cohort study

Background: It is not known whether smoking by mothers during pregnancy is associated with headache in their offspring. Methods: Two prospective cohorts of 869 children aged 10-11 years from Ribeirao Preto (RP) and 805 children aged 7-9 years from Sao Luis (SL) were studied. Data on maternal smoking were collected at birth. Primary headache was defined as a reporting of >= 2 episodes of headache in the past 2 weeks, without any associated organic symptoms. Results: Prevalence of headache was 28.1% in RP and 13.1% in SL as reported by the mothers and 17.5% in RP and 29.4% in SL as reported by the children. Agreement between mothers' report and children's self-report of primary headache in the child was poor. After adjustment, children whose mothers smoked >= 10 cigarettes per day during pregnancy presented higher prevalence of primary headache than their counterparts in both cohorts, as reported by the mother and in RP as reported by the children. Conclusions: Maternal smoking during pregnancy was associated with headache in 7- to 11-year-olds. With one exception, the consistency of the results, despite poor agreement between maternal and children reports of headache, indicates that maternal smoking during pregnancy may contribute to headaches in their children.

Cortisol Profile and Clinical Evaluation of Canine Neonates Exposed Antenatally to Maternal Corticosteroid Treatment

Contents The effects of glucocorticoids on both foetal canine lung and endogenous serum cortisol concentration have not been clearly delineated. Therefore, we aimed to investigate whether maternal corticosteroid treatment can alter maternal and neonatal cortisol profile and improve neonatal vitality. We allocated six bitches of different breeds and their neonates into two groups: control group (CONT) maternal administration of saline solution at 55days post-ovulation (n=3); and betamethasone group (BETA) administration of a single dose of 0.5mg/kg betamethasone (Celestone Soluspan(R)) at 55days post-ovulation (n=3). Caesarean sections were scheduled for day 63 after ovulation. However, BETA group dams showed precocious signs of labour, and c-sections were performed at 58days post-ovulation. Maternal and neonatal evaluations were performed periodically between betamethasone administration and birth, respectively. Neonates from both groups presented unsatisfactory (<5) Apgar score at birth. However, in spite of an earlier improvement on vitality found on CONT group and the premature delivery on BETA group, both groups showed acceptable Apgar score 120min after birth. Neonatal cortisol concentrations were higher on CONT group compared to BETA group at birth. In addition, a gradual decrease on maternal cortisol concentrations was observed in the BETA group from treatment until parturition. These findings suggest that despite the down-regulation on the hypothalamic-pituitary-adrenal axis and the induction of premature delivery, betamethasone treatment was able to provide similar vitality when compared to the untreated neonates born at term.

The double task of preventing malnutrition and overweight: a quasi-experimental community-based trial

Background: The Maternal-Child Pastoral is a volunteer-based community organization of the Dominican Republic that works with families to improve child survival and development. A program that promotes key practices of maternal and child care through meetings with pregnant women and home visits to promote child growth and development was designed and implemented. This study aims to evaluate the impact of the program on nutritional status indicators of children in the first two years of age. Methods: A quasi-experimental design was used, with groups paired according to a socioeconomic index, comparing eight geographical areas of intervention with eight control areas. The intervention was carried out by lay health volunteers. Mothers in the intervention areas received home visits each month and participated in a group activity held biweekly during pregnancy and monthly after birth. The primary outcomes were length and body mass index for age. Statistical analyses were based on linear and logistic regression models. Results: 196 children in the intervention group and 263 in the control group were evaluated. The intervention did not show statistically significant effects on length, but point estimates found were in the desired direction: mean difference 0.21 (95%CI −0.02; 0.44) for length-for-age Z-score and OR 0.50 (95%CI 0.22; 1.10) for stunting. Significant reductions of BMI-for-age Z-score (−0.31, 95%CI −0.49; -0.12) and of BMI-for-age > 85th percentile (0.43, 95%CI 0.23; 0.77) were observed. The intervention showed positive effects in some indicators of intermediary factors such as growth monitoring, health promotion activities, micronutrient supplementation, exclusive breastfeeding and complementary feeding. Conclusions: Despite finding effect measures pointing to effects in the desired direction related to malnutrition, we could only detect a reduction in the risk of overweight attributable to the intervention. The findings related to obesity prevention may be of interest in the context of the nutritional transition. Given the size of this study, the results are encouraging and we believe a larger study is warranted.

Postpartum depression and child development in first year of life

The aim of the study was to investigate the characteristics of infant development at four, eight and twelve months of age, as result of postpartum depression. The prevalence of Postpartum Depression - measured by the Edinburgh Postnatal Depression Scale - at four months after delivery was 30.3%; at eight months, 26.4%; and at 12 months, 25.0%. Chi-square tests were used to compare children of mothers with and without Postpartum Depression in relation to developmental milestones. It was found developmental delay in infants of mothers with Postpartum Depression in: two interactional indicators at four months, two motor indicators at eight months and one gross motor indicator at twelve months. However, children of mothers with Postpartum Depression showed better results in one fine motor and in two language items at 12 months. The results point to the necessity of considering external and internal factors of mother and infant in the study of the effects of maternal depression on child development.

Relazione gestante-feto, modalità del parto e sviluppo fisico del bambino

Extensive literature outlined that the quality of the mother-foetus relationship is considered the main feature with regard to the quality of postnatal mother-infant interaction and also to the child’s psychical development. Nowadays the relationship between the pregnant woman and her foetus is viewed as the central factor of the somatic dialogue between the functioning of the maternal and the foetal organisms. This dialogue is responsible for the physic development of the child, as well as of its psychosomatic structure. Therefore the research area has necessarily had to extend to the analysis of psychological processes concerning: the pregnancy, the couple that is bound by parenthood, the influence of intergenerational dynamics. In fact, the formation of maternal identity, as well as that of the relationship between the woman and the foetus, refers to the pregnant woman’s relationship with her parents, especially with her mother. The same pregnancy, considered as a psychosomatic event, is directly influenced by relational, affective and social factors, particularly by the quality of the interiorized parental relations and the quality of the current relationships (such as that with her partner and with her family of origin). Some studies have begun to investigate the relationship between the pregnant woman and the foetus in term of “prenatal attachment” and its relationship with socio-demographic, psychological e psychopathological aspects (such as pre and post partum depression), but the research area is still largely unexplored. The present longitudinal research aimed to investigate the quality of the pregnant womanfoetus relationship by the prenatal attachment index, the quality of the interiorized relationship with woman’s parents, the level of alexithymic features and maternity social support, in relation with the modulation of the physiology of delivery and of postpartum, as well as of the physical development of the child. A consecutive sample of 62 Italian primipara women without any kind of pathologies, participated in the longitudinal study. In the first phase of this study (third trimester of the pregnancy), it has investigated the psychological processes connected to the affective investment of the pregnant women towards the unborn baby (by Prenatal Attachment Inventory), the mothers’ interiorized relationship with their own parents (by Parental Bonding Instrument), the social and affective support from their partner and their family of origin are able to supply (by Maternity Social Support Scale), and the level of alexithymia (by 20-Toronto Alexithymia Scale). In the second phase of this study, some data concerning the childbirth course carried out from a “deliverygram” (such as labour, induction durations and modalities of delivery) and data relative to the newborns state of well-being (such as Apgar and pH indexes). Finally, in the third phase of the study women have been telephoned a month after the childbirth. The semistructured interview investigated the following areas: the memory concerning the delivery, the return to home, the first interactions between the mother and the newborn, the breastfeeding, the biological rhythms achieved from newborns. From the data analysis a sample with a good level of prenatal attachment and of support social and a good capability to mental functioning emerged. An interesting result is that the most of the women have a great percentage of “affectionless control style” with both parents, but data is not sufficient to interpret this result. Moreover, considering the data relative to the delivery, medical and welfare procedures, that have been necessary, are coherent with the Italian mean, while the percentage of the caesarean section (12.9%) is inferior to the national percentage (30%). The 29% of vaginal partum has got epidural analgesia, which explains the high number (37%) of obstetrician operations (such as Kristeller). The data relative to the newborn (22 male, 40 female) indicates a good state of well-being because Apgar and pH indexes are superior to 7 at first and fifth minutes. Concerning the prenatal phase, correlation analysis showed that: the prenatal attachment scores positively correlated with the expected social support and negatively correlated with the “externally oriented thinking” dimension of alexithymia; the maternity social support negatively correlated with total alexithymia score, particularly with the “externally oriented thinking” dimension, and negatively correlated with maternal control of parental bonding. Concerning the delivery data, there are many correlations (after all obvious) among themselves. The most important are that the labour duration negatively correlated with the newborn’s index state of well-being. Finally, concerning the data from the postpartum phase the women’ assessments relative to the partum negatively correlated with the duration of the delivery and positively correlated with the assessment relative to the return to home and the interaction with the newborn. Moreover the length of permanence in the hospital negatively correlated with women’s assessments relative to the return to home that, in turn, positively correlated with the quality of breastfeeding, the interaction between the mother and the newborn and the biological regulation of the child. Finally, the women’ assessments relative to breastfeeding positively correlated with the mother-child interactions and the biological rhythms of children. From the correlation analysis between the variables of the prenatal phase and the data relative to the delivery, emerged that the prenatal attachment scores positively correlated with the dilatation stage scores and with the newborn’s Apgar index at first minute, the paternal care dimension of parental bonding positively correlated with the lengths of the various periods of childbirth like so the paternal control dimension with placental stage. Moreover, emerged that the expected social support positively correlated with the lengths of the various periods of childbirth and that the global alexithymia scores, particularly “difficulty to describe emotions” dimension, negatively correlated with total childbirth scores. From the correlation analysis between the variables of the prenatal phase and variable of the postpartum phase emerged that the total alexithymia scores positively correlated with the time elapsed from the childbirth to the breastfeeding of the child, the difficulty to describe emotions dimension of the alexithymia negatively correlated with the quality of the breastfeeding, the “externally oriented thinking” dimension of the alexithymia negatively correlated with mother-child interactions, and finally the paternal control dimension of the parental bonding negatively correlated with the time elapsed from the child to the breastfeeding of the child. Finally, from the analysis of the correlation between the data of the partum and the women’s assessments of the postpartum phase, emerged the negative correlation between the woman’s assessment relative to the delivery and the quantitative of obstetrician operations and the lengths of the various periods of childbirth, the positive correlation between the women’s assessment about the length of delivery periods and the real lengths of the same ones, the positive relation between woman’s assessment relative to the delivery and the Apgar index of children. In conclusion, there is a remarkable relation between the quality of the relationship the woman establishes with the foetus that influences the course of the pregnancy and the delivery that, in turn, influences the postpartum outcome, particularly relative to the mother-children relationship. Such data should be confirmed by heterogeneous populations in order to identify vulnerable women and to project focused intervention.

Equine and human mutual welfare: a whole subject? Critical aspects and possible strategies in equine-assisted activities and therapies

General aim of the study is equine welfare, particularly concerning different husbandry methodic and inter-specific relational factors. Specific aim is the evaluation of possible mutual (to humans and to equines) benefits and the analysis of critical factors/strength points, of human-horse relationship within Therapeutic Riding context (TR). The peculiarities of human-horse relationship (compared to the bond with “Pet”) are analyzed, concerning their socio-anthropological, psychological, psycho-dynamic distinctive characteristics. 8 European representative therapeutic riding centers (TRC) were therefore selected (on the basis of their different animals’ husbandry criteria, and of the different rehabilitative methodologies adopted). TRC were investigated through 2 different questionnaires, specifically settled to access objective/subjective animal welfare parameters; the quality of human-horse relationship; technicians’ emotional experienced. 3 Centers were further selected, and behavioral (145 hours of behavioral recording) and physiological parameters (heart rate and heart rate variability) were evaluated, aimed to access equine welfare and horses’ adaptive responses/coping (towards general environment and towards TR job). Moreover a specific “handling-task” was ideated and experimented, aimed to measure the quality of TR technicians-horses relationship. We did therefore evaluate both the individual horses’ responses and the possible differences among Centers. Data collected highlight the lack of univocal standardized methodic, concerning the general animals’ management and the specific methodologies (aimed to improve animal welfare and to empower TR efficacy). Some positive and some critical aspects were detected concerning TR personnel-horse relationship. Another experimental approach did evaluate the efficacy (concerning the mutual benefits’ empowerment) of an “ethologically-fitted” TR intervention, aimed to educate children to and through the relationship with horses. Our data evidenced that the improvement of human horse relationship, through structured educational programs for TR personnel might have important consequences both to human and equine welfare.
