Midwives in the UK: an exploratory study of providing newborn feeding support for postpartum mothers in the hospital

Our objective was to explore English midwives' views and experiences of supporting mothers with feeding their newborn baby. Grounded theory methodology was used. Data were collected using in-depth interviews from 30 midwives in the North of England. Data were analyzed using constant comparison techniques. Midwives were theoretically sampled for interview from a pool of volunteers recruited from a poster promoting the study in the clinical areas. Overall, hospital midwives felt that they did not have enough time to support mothers with feeding their neonate. To cope with these time constraints, midwives developed practices of rationing the time that they spent with mothers, and the rationing of resources available to mothers, to help them process mothers through the hospital services. These practices have important implications for the success of breastfeeding in hospitals as the practices by providers who are assigned to help breastfeeding initiation described here may inhibit the breastfeeding process.

血清低密度脂蛋白胆固醇直接测定与Friedewald公式计算结果比较

采用聚乙烯硫酸（ＰＶＳ）沉淀法测定血清低密度脂蛋白胆固醇（ＬＤＬ－Ｃ）值，同时应用Ｆｒｉｅｄｅｗａｌｄ公式计算ＬＤＬ－Ｃ含量，并对两法结果进行比较分析，提出当甘油三脂（ＴＧ）＜４．５２ｍｍｏｌ／Ｌ时，Ｆ公式计算法可代替ＰＶＳ法，当ＴＧ＞４．５２ｍｍｏｌ／Ｌ时，不宜用Ｆ公式计算ＬＤＬ－Ｃ的值。

定君生胶囊用于妊娠期细菌性阴道病的临床观察

目的调查妊娠期细菌性阴道病(BV)的发病情况,观察定君生胶囊治疗细菌性阴道病的有效性。方法采用珠海市银科生物技术应用研究所生产的细菌性阴道病快速检测卡,对不同孕周的1500名孕妇进行BV筛查,确定妊娠期细菌性阴道病的发病率。对确诊为BV的孕妇266例,随机分为两组。定君生组:136例,给予定君生胶囊(乳杆菌活菌胶囊)阴道给药治疗;孚舒达组:130例,给予孚舒达栓(复方甲硝唑栓)阴道给药治疗。两组均连续用药10d,停药7d后复查。结果妊娠期BV的检出率为17.73%。定君生胶囊治疗BV的总有效率为92.65%,孚舒达栓治疗BV的总有效率为91.53%,二者差异无显著性(P>0.5)。结论妊娠期BV的发病率较高。定君生胶囊能有效改善阴道内生态环境,治疗妊娠期细菌性阴道病安全、有效,易为孕妇所接受。     

Allergen-Specific IgE Antibodies against Antigenic Components in Cow Milk and Milk Substitutes

Crossed radioimmunoelectrophoresis (CRIE) was used to study the presence of serum IgE against antigenic components of cow milk in 21 selected milk-allergic patients. The amount of each IgE specificity was estimated by a scoring system. The milk-allergic children had mainly IgE against alpha-lactalbumin, beta-lactoglobulin, albumin and immunoglobulin, the four major proteins of bovine whey, as well as IgE against three casein components. A serum pool from 1000 normal adults had IgE against the same whey protein, but in smaller amounts, and no IgE against the casein components. Eight cow milk-based formulae, commonly used for infant feeding, and goat milk were studied by the same method. It was found that six of the milk substitutes did not differ significantly from cow milk in antibody binding, but the two hydrolysed casein products, Nutramigen and Pregestimil, consisted of such small molecules that the rabbit antisera could not precipitate the hydrolysed proteins in the gels on the CRIE plates. It was therefore not possible to study their IgE binding, if any, by this method.
