孕妇血浆尿酸正常值及其在妊娠高血压综合征的诊断价值

测定了133名正常孕妇和133名妊高征患者的血浆尿酸,其平均值分别为324.00μmol/L和388.91μmol/L,有显著性差异,且尿酸增高程度与病情轻重有关,但两组尿酸分布大部分重叠。确定了孕妇血浆尿酸的95％正常值上限为445μmol/L,在此基础上评价了尿酸对妊高征的诊断价值,认为血浆尿酸只适合用于判断妊高征病情严重程度,不宜用于妊高征的诊断和鉴别诊断。

Does Supplementary Prenatal Nursing and Home Visitation Support Improve Resource Use in a Universal Health Care System? A Randomized Controlled Trial in Canada

ABSTRACT: Background: The addition of supplementary prenatal support may improve the health and well‐being of high‐risk women and families. The objective of this randomized controlled trial was to examine the impact of supplementary prenatal care on resource use among a community‐based population of pregnant women. Methods: Pregnant women from three urban maternity clinics were randomized (a) to current standard of physician care, (b) to current standard of care plus consultation with a nurse, or (c) to (b) plus consultation with a home visitor. Participants were 1,352 women who received 3 telephone interviews. The primary outcome was resource use (e.g., attended prenatal classes, used nutritional counseling). Results: Overall, those in the nurse intervention group were more likely to attend an “Early Bird” prenatal class and parenting classes, and to use nutrition counseling and agencies that assist with child care. Women provided with extra nursing and home visitation supports were more likely to use a written resource guide, nutrition counseling, and agencies that assist with child care. Among women at higher risk (e.g., language barriers, young maternal age, low income), the nurse intervention significantly increased use of early prenatal classes, whereas the nurse and home visitor intervention significantly increased use of the written resource guide and nutrition counseling. The intervention substantially increased the amount of information received on numerous pregnancy‐related topics but had little impact on resource use for mental health and poverty‐related needs. Among those with added support, resource use among low‐risk women was generally greater than among high‐risk women. Conclusions: Additional support provided by nurses, or nurses and home visitors, can successfully address informational needs and increase the likelihood that women will use existing community‐based resources. This finding was true even for high‐risk women, although this intervention did not reduce the difference in resource use between high‐ and low‐risk women. (BIRTH 33:3 September 2006)     

Endocrinology: Predictive value of serum oestradiol concentrations and oocyte number in severe ovarian hyperstimulation syndrome

Ovarian hyperstimulation syndrome (OHSS) is a serious complicationof gonadotrophin usage but it is difficult to accurately predictits occurrence. Previous investigators have identified the combinationof high oestradiol concentrations and oocyte number as beingpredictive in 80% of cases. In this study we sought to identifythe incidence of severe OHSS in patients with high oestradiolconcentrations and large numbers of oocytes and to evaluatethe importance of pregnancy in the development of OHSS. Between1990 and 1993, we studied 139 cycles using two assisted reproductivetechniques [oocyte donor, n =72; in-vitro fertilization (IVF),n = 67] in which either oestradiol (>4000 pg/ml), oocytenumber (>25), or both were elevated. OHSS was diagnosed bystandard criteria. There were no cases of severe OHSS in theoocyte donor group and six in the IVF group. Among 10 patientswith oestradiol concentration >6000 pg/ml and >30 oocytes,only one had OHSS (10%). The relative risk of OHSS with pregnancywas 12 (confidence interval 2.18–66.14). We conclude thatthe risk of OHSS even at high levels of stimulation is lowerthan previously believed. Secondly, donors have a very low riskof OHSS, probably because of the absence of pregnancy. As such,cryopreservation of all oocytes in IVF cycles is a reasonablealternative to cycle cancellation or use of adjunctive medication.     

The epidemiology of bacteriuria in pregnancy

Bacteriuria in pregnancy is now easily detected by various techniques adapted to the office setting. It is importtant to screen for bacteriuria in pregnancy because 3%–10% of pregnant women will be positive for occult infection. Up to 30% thus infected will subsequently develop pyelonephritis later in pregnancy, which in turn is associated with premature labor and delivery. This entity must be detected and treated as early as possible in pregnancy to prevent these adverse effects.Presented at the Zambon Symposium on Bacteriuria in Pregnancy, International Urogynecological Association Annual Meeting, Riva del Garda, Italy, September 13, 1989.Dedicated to the memory of Edward H.

母体钙代谢与补钙对妊娠的影响

妊娠期缺钙严重影响母婴的安全健康 ,其原因是由于妊娠期母体钙代谢发生变化 ,使母体血清游离钙离子浓度降低 ,血清铅浓度增高。有关研究表明 ,母体缺钙导致血铅竞争性过高 ,使胎儿身长、体重均小于胎龄儿 ,胎儿宫内发育迟缓的发生率增高 ,甚至发生早产、死胎等。同时发现血清钙离子可能对内源性一氧化氮合成释放起调节作用 ,而内皮素是最强的缩血管物质之一 ,母体补钙可调节一氧化氮与内皮素的平衡 ,从而降低妊高征的发生率。因此孕期补充钙剂是非常重要的。
