Sexist Attitudes in Adolescents: Prevalence and Associated Factors.

Gender violence is a major public health issue. The aim of this study was to determine the prevalence of sexist attitudes that could be associated with said violence, and to identify some sociodemographic variables that predict sexism. A cross-sectional observational study was conducted with 723 adolescents between the ages of 14 to 19. Their explicit sexist attitudes were measured with the EVAMVE and EARG scales, and their implicit attitudes were measured with a series of assessment items regarding the behavior of the protagonists of a video and a story in which a young couple interacts. Explicit and implicit sexist attitudes were detected in adolescents of both sexes. Qualitatively, the assessment of the behavior of the female protagonist is striking. Regarding the sexism predictors, it was found that male adolescents, those born outside of Spain, those who were studying in a public school, those whose parents did not have university studies, and those who consumed the most pornography presented attitudes that were significantly more sexist. These results suggest that it is necessary to strengthen education in equality and prevention of gender violence in adolescents, and to develop affective-sexual education programs.

Effectiveness of 2 interventions for independent oral feeding in preterms.

INTRODUCTION: Oral feeding of preterm newborns (PTNB) is hampered by their immaturity and intercurrent diseases, which can prolong their hospital stay. The objective of this study was to assess the effectiveness of a program that combines tactile, kinesthetic and oral stimulation (T + K + OS) compared to another intervention based on exclusively oral stimulation (OS), in the time necessary to achieve independent feeding and hospital discharge. PATIENTS AND METHODS: A clinical study of 2 randomized groups (OS vs. T + K + OS) was carried out on 42 PTNB with gestational age between 27-32 weeks and birth weight > 900 g. The stimulation programs were carried out in sessions of 15 min, for 10 days. RESULTS: The PTNBs in the T + K + OS group achieved independent oral feeding earlier, compared to the OS group (24.9 ± 10.1 vs. 34.1 ± 15.6 days, P = .02). An analysis of covariance was performed, which confirmed that the birth weight and gestational age covariates had significant effects on time to reach suction feeding (birth weight: F[1, 38] = 5.79; P = .021; gestational age: F[1, 38] = 14.12; P = .001) and that once its effect was controlled, the intervention continued to have a significant effect (F[1, 38] = 6.07; P = .018). The T + K + OS group, compared to the OS group, achieved an earlier hospital discharge (39 ± 15 vs. 45 ± 18 days), although the differences were not significant (P = .21). CONCLUSIONS: Combined therapies that include T + K + OS are more effective than OS alone, in order to achieve independent oral feeding in PTNBs.

Introducción: La alimentación oral de los recién nacidos pretérmino (RNPT) está dificultada por su inmadurez y enfermedades intercurrentes, lo que puede prolongar su estancia hospitalaria. El objetivo de este estudio fue valorar la efectividad de un programa que combina la estimulación táctil, kinestésica y oral (ET+K+O) frente a otro de estimulación oral sola (EO), en el tiempo necesario para lograr la alimentación independiente y el alta hospitalaria. Pacientes y métodos: Estudio clínico de 2 grupos aleatorizados (EO vs. ET+K+O), realizado en 42 RNPT con una edad gestacional entre 27-32 semanas y un peso al nacimiento>900g. Los programas de estimulación fueron realizados en sesiones de 15min, durante 10 días. Resultados: Los RNPT del grupo de ET+K+O consiguieron antes la alimentación oral independiente, en comparación con el grupo de EO (24,9±10,1 vs. 34,1±15,6 días, p=0,02). Se realizó un análisis de covarianza, observando que las covariables PN y EG tuvieron efectos significativos en el tiempo hasta alcanzar la alimentación por succión (peso al nacimiento: F[1, 38]=5,79; p=0,021; edad gestacional: F[1, 38]=14,12; p=0,001) y que una vez controlado su efecto, la intervención seguía teniendo un efecto significativo (F[1, 38]=6,07; p=0,018). El grupo de ET+K+O, en comparación con el de EO, consiguió antes el alta hospitalaria (39±15 vs. 45±18 días), si bien la diferencia no fue significativa (p=0,21). Conclusiones: Las terapias combinadas que asocian ET+K+O son más eficaces que la EO sola, para lograr la alimentación oral independiente en los RNPT. (AU)

Anquiloglosia en el lactante amamantado. Puesta al día / Ankyloglossia in breastfeeding infants. An update

El frenillo lingual corto, o anquiloglosia, puede generar problemas durante la lactancia con repercusión en el desarrollo del lactante, daño en el pezón de la madre y abandono precoz de la lactancia. Actualmente no existe homogeneidad en los criterios diagnósticos, lo que ocasiona tanto sobrediagnóstico como infradiagnóstico de esta alteración, con las consecuencias clínicas que ello conlleva. La dificultad en el abordaje radica en saber cuándo se trata de variantes anatómicas normales o de un frenillo lingual sin repercusión funcional, y cuándo los problemas de lactancia, que clásicamente se le atribuyen se deben realmente al frenillo. Alrededor del 50 % de los niños con frenillo lingual corto no presenta problemas de lactancia o estos se resuelven con apoyo y asesoramiento. En el resto de casos se puede recurrir a tratamiento quirúrgico. En este artículo se ha realizado una actualización de la clasificación y tratamiento de la anquiloglosia que permitirá a los profesionales un manejo adecuado de estos pacientes

Short frenulum, or ankyloglossia, may lead to breastfeeding problems, with an impact on infant development, nipple damage, and early abandonment of breastfeeding. There are currently no homogeneous diagnostic criteria, thus leading to both overdiagnosis and underdiagnosis and associated clinical consequences. The challenge to approach this condition lies in establishing whether it is a normal anatomical variation or a lingual frenulum without a functional impact and when breastfeeding difficulties which are typically attributed to it are actually caused by the frenulum. Approximately 50 % of ankyloglossia cases do not result in breastfeeding problems or these can be resolved with support and advice. Surgery may be proposed for the rest of the cases. This article offers an update on the classification and treatment of ankyloglossia, which will help health care providers to provide an adequate management to these patients

[The impact of Covid-19 pandemic on breastfeeding and birth care. The importance of recovering good practices.] / Impacto de la pandemia de Covid-19 en la lactancia y cuidados al nacimiento. Importancia de recuperar las buenas prácticas.

The SARS-CoV-2 pandemic has had a major impact on birth care and lactation. The lack of knowledge regarding the transmission mechanisms and the potential risks for the mother and the newborn, even when the vertical transmission of the virus has not been demonstrated, has led to the abandonment of practices such as skin-to-skin and the early initiation of breastfeeding (BF), which offer great benefits for maternal and child health. Taking into account the available scientific evidence and the protective effect of BF, the World Health Organization (WHO), and other organisms recommend, in cases of suspected or confirmed SARS-CoV-2 infection of the mother, maintaining mother-child contact and BF, adopting preventive measure procedures to minimize the risk of contagion. These measures include hand hygiene, before and after contact with the newborn and the use of a mask. If a temporary separation of mother and child is required, it is recommended to feed the newborn with expressed breast milk. The presence of IgA antibodies against SARS-CoV-2 has been confirmed in the milk of infected women, so BF could reduce the clinical impact of the disease in the infant, if it becomes infected.

La pandemia por el SARS-CoV-2 ha tenido un gran impacto en la atención al nacimiento y la lactancia. El desconocimiento de los mecanismos de contagio y los riesgos potenciales para la madre y el recién nacido (RN), aun cuando no se ha demostrado la transmisión vertical del virus, ha propiciado el abandono de prácticas como el piel con piel y el inicio precoz de la lactancia materna (LM), que ofrecen grandes beneficios para la salud materno-infantil. Teniendo en cuenta la evidencia científica disponible y el efecto protector de la LM, la Organización Mundial de la Salud (OMS) y otros organismos recomiendan mantener el contacto madre-hijo y la LM en casos de sospecha o infección confirmada por SARS-CoV-2 en la madre, adoptando procedimientos preventivos para minimizar el riesgo de contagio, como la higiene de las manos, antes y después del contacto con el RN, así como el uso de mascarilla. Si se precisa una separación temporal de la madre y el niño, se recomienda alimentar al RN con leche materna extraída. Se ha confirmado la presencia de anticuerpos IgA frente al SARS-CoV-2 en leche de mujeres infectadas, por lo que la LM podría disminuir el impacto clínico de la enfermedad en el lactante, si llega a contagiarse.

Breastfeeding Rates and Programs in Europe: A Survey of 11 National Breastfeeding Committees and Representatives.

INTRODUCTION: Among the world's regions, the WHO European Region has the lowest rates of exclusive breastfeeding at the age of 6 months with approximately 25%. Low rates and early cessation of breastfeeding have important adverse health consequences for women, infants, and young children. Protecting, promoting, and supporting breastfeeding are a public health priority. OBJECTIVES: National breastfeeding data and monitoring systems among selected European countries and the WHO European Region are compared. Mechanisms for the support, protection, and promotion of breastfeeding are reviewed and successes and challenges in implementation of national programs are presented. METHODS: National representatives of national breastfeeding committees and initiatives in 11 European countries, including Belgium, Croatia, Denmark, Germany, Ireland, Italy, The Netherlands, Norway, Spain, Sweden, and Switzerland, participated in a standardized survey. Results are evaluated and compared in a narrative review. RESULTS: Variation exists in Europe on breastfeeding rates; methodology for data collection; and mechanisms for support, protection, and promotion of breastfeeding. Directly after birth, between 56% and 98% of infants in all countries were reported to receive any human milk, and at 6 months 38% to 71% and 13% to 39% of infants to be breastfed or exclusively breastfed, respectively. National plans addressing breastfeeding promotion, protection, and support exist in 6 of the 11 countries. CONCLUSIONS: National governments should commit to evidence-based breastfeeding monitoring and promotion activities, including financial and political support, to improve breastfeeding rates in the Europe. Renewed efforts for collaboration between countries in Europe, including a sustainable platform for information exchange, are needed.

[Effectiveness of an intervention to improve breastfeeding knowledge and attitudes among adolescents]. / Eficacia de una intervención para mejorar conocimientos y actitudes sobre lactancia materna en adolescentes.

OBJECTIVE: Breastfeeding constitutes a priority in Public Health due to the multiple benefits it offers. The decision to breastfeed is usually made before pregnancy, and therefore it is important to include adolescents in breastfeeding promotion programs. The aim of the study was to evaluate the effectiveness of a programme to improve knowledge and attitudes toward breastfeeding among teenager. METHODS: Pretest-posttest randomized controlled study, carried out in 2008 in Tenerife. 970 teenagers participated (14,6±0.9 years), 506 experimental group (EG) and 524 control group (CG). Before the intervention and 4 weeks after, students completed a questionnaire to evaluate their knowledge and attitudes towards breastfeeding. The performed intervention consisted of: a talk, video projection, informative leaflets, narrative short stories and role-play activities. Chi-square test, student's t-test, Cronbach's alpha coefficient, repeated measures variance analysis and covariance analysis were used. RESULTS: There were no significant differences between the two groups regarding knowledge (EG: 3.9±1.5, CG: 3.8±1.5) or attitudes towards breastfeeding, before the intervention. The same applies when compared by gender, school year, parents' occupation and type of school. The post-intervention questionnaire showed a significant increase in the level of knowledge of students from EG (EG: 6.9 ± 1.5, CG: 4.4 ± 1.8; p <0.001) as well as a higher percentage of positive attitudes towards breastfeeding (GE: 71.13±28.5, GC: 54.27±28.9, p <0,001). Covariance analysis showed a significant effect (p <0,05) on attitudes towards breastfeeding of the variables gender and previous contact with breastfeeding. CONCLUSIONS: The educational program carried out is effective as a method to improve knowledge and attitudes toward breastfeeding among teenagers.

OBJETIVO: La lactancia materna (LM) por sus múltiples beneficios constituye una prioridad en salud pública. La decisión de amamantar generalmente se toma antes del embarazo, siendo importante incluir a los adolescentes en los programas de promoción. El objetivo del estudio fue evaluar la eficacia de un programa dirigido a mejorar los conocimientos y actitudes de los adolescentes sobre la LM. METODOS: Estudio longitudinal pre-post-intervención, controlado y aleatorizado, realizado en 2008 en Tenerife. Participaron 970 adolescentes (14,6±0.9 años), 506 en el grupo experimental (GE) y 524 en el grupo control (GC). Antes de la intervención y a las 4 semanas cumplimentaron un cuestionario sobre co- nocimientos y actitudes hacia la LM. La intervención incluyó: charla, vídeo, folletos informativos, relatos y rol-play. Se han utilizado las pruebas chi-cuadrado, t de student, coeficiente Alfa de Cronbach, análisis de varianza de medidas repetidas y análisis de covarianza. RESULTADOS: Antes de la intervención no había diferencias significativas entre ambos grupos en los conocimientos (GE: 3.9±1.5, GC: 3.8±1.5) y actitudes sobre LM, ni diferencias asociadas al sexo, curso escolar, profesión de los padres y tipo de colegio. Tras la intervención, el GE registró un aumento significa- tivo en sus conocimientos (GE: 6.9±1.5, GC: 4.4±1.8 p <0.001), así como un mayor porcentaje de actitudes positivas hacia la LM (GE: 71.13±28.5, GC: 54.27±28.9, p <0,001). El análisis de covarianza reflejó un efecto significativo (p <0,05) de las variables sexo y contacto previo con la LM en las actitudes. CONCLUSIONES: El programa educativo desarrollado es eficaz para mejorar los conocimientos y actitudes sobre LM en adolescentes.

Levels of Silicon in Maternal, Cord, and Newborn Serum and Their Relation With Those of Zinc and Copper.

BACKGROUND: Evidence of silicon's importance to health has been gradually accumulating. Nevertheless, there are few studies comparing serum silicon levels in newborns with maternal levels. Likewise, little is known concerning the inter-relation between silicon and other trace elements. OBJECTIVE: The present study evaluated maternal and newborn levels of serum silicon and their relation to those of zinc and copper. METHODS: We measured serum silicon, copper, and zinc in 66 pregnant women, in the umbilical cord of their infants, and in 44 newborns, by atomic absorption spectrophotometry. All the samples were from fasted subjects. RESULTS: Serum silicon level in term newborns (20.6 ±â€Š13.2 µmol/L) was significantly higher than in umbilical cord (8.9 ±â€Š3.5 µmol/L; P < 0.0001). Mean serum silicon level in maternal vein (7.7 ±â€Š3.4 µmol/L) was lower than that in umbilical cord, although differences were not significant. We also found higher levels of zinc (P = 0.008) and lower levels of copper (P < 0.0001) in cord blood compared with maternal blood. Umbilical venous/maternal venous level ratios of zinc, copper, and silicon were 1.5 ±â€Š0.5, 0.2 ±â€Š0.1, and 1.3 ±â€Š0.7, respectively. There was a positive correlation between silicon and zinc levels (r = 0.32), and a negative correlation between copper and zinc levels (r = -0.35). CONCLUSIONS: It seems that there is a positive gradient of silicon from the mother to her fetus. Silicon levels were higher in newborn than in cord blood, and correlated significantly with that of zinc but not copper. Additional investigations are needed to further define the role of silicon and its interaction with other trace elements during the perinatal period.

[Mastitis update.] / Mastitis. Puesta al día.

Mastitis is one of the main causes of avoidable cessation of breastfeeding which increases morbidity in childhood, however, there is no uniformity in diagnostic and therapeutic criteria. The diagnosis of acute mastitis is mainly clinical. Only in certain cases, a milk culture is indicated. Regarding treatment of mastitis, it is fundamental to empty the breast, so breastfeeding should continue. It is recommended to start antibiotic therapy if symptoms persist or if there is considerable clinical impact. There is insufficient evidence of the importance of other types of mastitis (subclinical and subacute). There is also a lack of evidence that these types of mastitis are responsible for breast pain or for low infant weight gain. Furthermore, there is not enough evidence regarding the effectiveness of probiotics in the treatment and prevention of mastitis.

La mastitis es una de las principales causas de abandono evitable de la lactancia materna, con el aumento de la morbimortalidad infantil que ello supone, pero no hay uniformidad en los criterios diagnósticos ni terapéuticos. El diagnóstico de la mastitis aguda es fundamentalmente clínico, y, solo en determinados casos, está indicado el cultivo de leche. El drenaje del pecho es fundamental en el tratamiento, por lo que debe mantenerse la lactancia. Si persisten los síntomas o si existe mucha repercusión clínica, se iniciará la antibioterapia. No hay pruebas suficientes de la etiopatogenia de otros tipos de mastitis (subclínica y subaguda) ni de que sean responsables del dolor mamario o el escaso aumento ponderal del lactante. Tampoco sobre la efectividad de los probióticos en el tratamiento y prevención de la mastitis. El objetivo es realizar una evaluación de la información disponible sobre la clínica, diagnóstico y tratamiento de las mastitis para ofrecer una visión actualizada del tema

La importancia de la nutrición materna durante la lactancia, ¿necesitan las madres lactantes suplementos nutricionales? / The importance of maternal nutrition during breastfeeding: Do breastfeeding mothers need nutritional supplements?

La leche materna es el mejor alimento para los recién nacidos y lactantes. Las reservas nutricionales de una mujer lactante pueden estar más o menos agotadas como resultado del embarazo y la pérdida de sangre durante el parto. La lactancia plantea necesidades nutricionales especiales, principalmente debido a la pérdida de nutrientes a través de la leche materna. El volumen de leche materna varía ampliamente. Los nutrientes presentes en la leche proceden de la dieta de la madre o de sus reservas de nutrientes. Para conseguir un buen estado nutricional durante la lactancia, la mujer tiene que aumentar la ingesta de nutrientes. La leche materna tiene una composición bastante constante y la dieta de la madre solo afecta a algunos nutrientes. El contenido de grasa de la leche materna varía con la dieta. El contenido de hidratos de carbono, proteína, calcio y hierro no cambia mucho incluso si la madre ingiere poca cantidad de estos en su dieta. Sin embargo, si la dieta de una madre es deficiente en vitaminas hidrosolubles y vitaminas A y D, su leche contiene menos cantidades de estos nutrientes. En cada visita posnatal tanto la madre como el niño deben ser examinados, y se debe proporcionar asesoramiento sobre la alimentación saludable. Durante la lactancia se debe evitar una dieta que aporte menos de 1.800cal al día

Breastmilk is the best food for newborns and infants. The nutritional stores of a lactating woman may be more or less depleted as a result of the pregnancy and the loss of blood during childbirth. Lactation raises nutrient needs, mainly because of the loss of nutrients, first through colostrum and then through breastmilk. Breastmilk volume varies widely. The nutrients present in this milk come from the diet of the mother or from her nutrient reserves. The conversion of nutrients in food to nutrients in breastmilk is not complete. To have good nutritional status the breastfeeding woman has to increase nutrient intake. Human breastmilk has a fairly constant composition, and is only selectively affected by the diet of the mother. The fat content of breastmilk varies somewhat. The carbohydrate, protein, fat, calcium and iron contents do not change much, even if the mother is short of these in her diet. A mother whose diet is deficient in thiamine and vitamins A and D, however, produces less of these in her milk. The mother should be given advice on consuming a mixed diet. At each postnatal visit, both the mother and the baby should be examined, and advice on the diets of both mother and infant should be provided. A satisfactory gain in the infant's weight is the best way to judge the adequacy of the diet of the infant. Mothers should not receive less than 1800 calories per day

[Motivations and perceived barriers to initiate or sustain breast- feeding among Spanish women]. / Motivaciones y barreras percibidas por las mujeres Españolas en relación a la lactancia materna.

OBJECTIVE: Breastfeeding for its multiple benefits is the best cost-effective health intervention and should be a public health priority. The aim of this study was to determine motivations and barriers perceived by mothers to initiate or to maintain breastfeeding. METHODS: A cross-sectional, observational study was carried in 2013 out among 569 mothers resident in Spain, with children under the age of 2, who completed a structured questionnaire. A two-stage sampling, stratified by Autonomous Communities and non-probabilistic within each community was used. RESULTS: 88% of the mothers were breastfeeding their children or had breastfed. At the time of the survey 66.6% had stopped breastfeeding, and the average age for weaning was 6.4 (SD 3.8) months. The main reason for stopping breastfeeding was maternal perceptions of insufficient milk supply (29%). The second reason was going back to work (18%). 67% of the mothers said that they made the decision to breastfeed on their own. The main disadvantages reported were: the difficulty to reconcile breastfeeding and work (43%), breastfeeding in public places (39%), more frequent nighttime awakenings (62%) and the reduced weight gain of the baby (29%). Going back to work was the main reason for choosing formula feeding (34%) and also for initiating partial breastfeeding (39%). CONCLUSIONS: The main disadvantages reported were: the difficulty to reconcile breastfeeding and work, breastfeeding in public places, more frequent nighttime awakenings and the reduced weight gain of the baby. Going back to work was the main reason for choosing formula feeding and also for initiating partial breastfeeding.

OBJETIVO: La lactancia materna (LM) por sus múltiples beneficios es la mejor intervención coste-efectiva en salud y debería constituir un objetivo prioritario de salud pública. El objetivo de este estudio fue conocer las motivaciones y barreras percibidas por las madres para iniciar o mantener la LM. METODOS: Estudio observacional transversal con 569 madres residentes en España en 2013, con hijos menores de 2 años que cumplimentaron un cuestionario estructurado. Muestreo bietápico, estratificado por comunidades autónomas y no probabilístico en cada comunidad. RESULTADOS: El 88% de las madres daban LM o lo habían hecho. La edad media del destete fue 6.4 (DE 3.8) meses. El principal motivo para suspender la lactancia fue la sensación de baja producción de leche (29%) seguido de la incorporación al trabajo (18%). El 67% de las madres indicaron que la decisión de amamantar la habían tomado ellas mismas. La dificultad para combinar la LM con la actividad laboral (43%), dar el pecho en lugares públicos (39%), los despertares nocturnos (62%) y el menor aumento de peso del lactante (29%) fueron los inconvenientes más referidos. La incorporación laboral fue el principal motivo para elegir la lactancia artificial (34%) y para iniciar la lactancia parcial (39%). CONCLUSIONES: La dificultad para combinar la LM con la actividad laboral, dar el pecho en lugares públicos, los despertares nocturnos y la menor ganancia de peso del lactante fueron los inconvenientes más referidos. La incorporación laboral fue el principal motivo para elegir la lactancia artificial y para iniciar la lactancia parcial.

[The importance of maternal nutrition during breastfeeding: Do breastfeeding mothers need nutritional supplements?]. / La importancia de la nutrición materna durante la lactancia, ¿necesitan las madres lactantes suplementos nutricionales?

Breastmilk is the best food for newborns and infants. The nutritional stores of a lactating woman may be more or less depleted as a result of the pregnancy and the loss of blood during childbirth. Lactation raises nutrient needs, mainly because of the loss of nutrients, first through colostrum and then through breastmilk. Breastmilk volume varies widely. The nutrients present in this milk come from the diet of the mother or from her nutrient reserves. The conversion of nutrients in food to nutrients in breastmilk is not complete. To have good nutritional status the breastfeeding woman has to increase nutrient intake. Human breastmilk has a fairly constant composition, and is only selectively affected by the diet of the mother. The fat content of breastmilk varies somewhat. The carbohydrate, protein, fat, calcium and iron contents do not change much, even if the mother is short of these in her diet. A mother whose diet is deficient in thiamine and vitamins A and D, however, produces less of these in her milk. The mother should be given advice on consuming a mixed diet. At each postnatal visit, both the mother and the baby should be examined, and advice on the diets of both mother and infant should be provided. A satisfactory gain in the infant's weight is the best way to judge the adequacy of the diet of the infant. Mothers should not receive less than 1800 calories per day.

Background: Breastfeeding for its multiple benefits is the best cost-effective health intervention and should be a public health priority. The aim of this study was to determine motivations and barriers perceived by mothers to initiate or to maintain breastfeeding. Methods: A cross-sectional, observational study was carried in 2013 out among 569 mothers resident in Spain, with children under the age of 2, who completed a structured questionnaire. A two-stage sampling, stratified by Autonomous Communities and non-probabilistic within each community was used. Results: 88% of the mothers were breastfeeding their children or had breastfed. At the time of the survey 66.6% had stopped breastfeeding, and the average age for weaning was 6.4 (SD 3.8) months. The main reason for stopping breastfeeding was maternal perceptions of insufficient milk supply (29%). The second reason was going back to work (18%). 67% of the mothers said that they made the decision to breastfeed on their own. The main disadvantages reported were: the difficulty to reconcile breastfeeding and work (43%), breastfeeding in public places (39%), more frequent nighttime awakenings (62%) and the reduced weight gain of the baby (29%). Going back to work was the main reason for choosing formula feeding (34%) and also for initiating partial breastfeeding (39%). Conclusions: The main disadvantages reported were: the difficulty to reconcile breastfeeding and work, breastfeeding in public places, more frequent nighttime awakenings and the reduced weight gain of the baby. Going back to work was the main reason for choosing formula feeding and also for initiating partial breastfeeding (AU)

A breastfeeding e-learning project based on a web forum.

OBJECTIVE: The Internet has introduced new ways of learning that may complement medical training during the residency period. We describe the experience with a new method of e-learning for training in human lactation and breastfeeding counselling. Pediatric residents participated in the Human Lactation Forum maintained by the Spanish Pediatric Association Breastfeeding Committee, a site on the Internet where parents may write in for pediatric advice on breastfeeding. METHODS: From April 2005 to May 2006, 42 pediatric residents from four hospitals in Spain received a month of intensive theoretical training on breastfeeding, and afterward, they took weekly turns answering parents' questions in the forum. Before and after the experience, they completed a pre-post knowledge test and an opinion postexperience questionnaire with open questions. A t-test was used to analyze the differences pre- and posttest; the opinion questionnaire was analyzed qualitatively. RESULTS: The mean age of participants was 28.3 years; 88% were women, and 80% were in their third or fourth year of residency. The percentage of correct answers was higher after participation in the program, and the difference had statistic significance. The residents estimated that nearly a half of their patients needed breastfeeding advice, and they thought that the program improved their knowledge of breastfeeding and their communication skills with mothers. On average, they spent 2.9 hours daily to answer the questions. CONCLUSIONS: The learning experience was positively evaluated by the participants and contributed to increase their knowledge and skills in breastfeeding issues. We think it is a good method for training future pediatricians on breastfeeding management. In addition, the instrument may contribute to improve lactation knowledge among pediatricians.

Maternal smoking and the vitamin D-parathyroid hormone system during the perinatal period.

OBJECTIVE: To evaluate the effect of smoking on the vitamin D-parathyroid hormone (PTH) system during the perinatal period. STUDY DESIGN: Sixty-one healthy women with singleton pregnancies and their newborns participated in a cohort study. We compared serum PTH and BsmI polymorphism of the vitamin D receptor gene, 25 hydroxyvitamin D (25(OH)D), 1,25 dihydroxyvitamin D, calcium, phosphorus, and bone alkaline phosphatase (bALP) in a smoking group (n = 32) versus a non-smoking group (n = 29), controlling for lifestyle confounders. The mothers were examined at 30 to 32 weeks and 38 to 40 weeks of pregnancy, and the infants were examined at 2 to 3 days of postnatal life. RESULTS: Mothers who smoked and their newborns showed decreased serum PTH (30-32 weeks, 26.9 +/- 10.7 pg/mL versus 37.1+/-19.5 pg/mL; 38-40 weeks, 32.2 +/- 13.5 pg/mL versus 46.2 +/- 21.9 pg/mL, P = .005; newborns, 43.4 +/- 21.8 versus 64.1 +/- 34.2 pg/mL, P = .02) and increased phosphorus. Newborns of mothers who smoked also had significantly lower anthropometric measurements and serum 25(OH)D (14.2 +/- 6.2 ng/mL versus 22.3 +/- 11.3 ng/mL, P = .009). In addition, pregnant women who smoked had lower bALP (30-32 weeks, 31 +/- 15 U/L versus 44+/-29 U/L; 38-40 weeks, 55 +/- 32 U/L versus 97 +/- 62 U/L, P = .005). CONCLUSIONS: Smoking during pregnancy negatively influences calcium-regulating hormones, leading to relative hypoparathyroidism in both the mother and their newborns.
