Role of diet in the therapy of urolithiasis

The data reviewed in this paper indicate that there is compelling direct and indirect evidence that certain dietary modifications can limit the risk for stone formation. Fluid therapy should be a front-line approach for all stone formers, because it is safe, cheap, and effective. Restricting sodium and animal-protein consumption produces changes in the urinary environment that should benefit the majority of stone formers, including a decrease in calcium and increase in citrate excretion. Minimizing the intake of processed goods limits sodium gluttony. These dietary modifications also reduce cardiovascular risks. Indiscriminant calcium restriction should be avoided, because it could accelerate stone formation and violate skeletal integrity. Oxalate restriction should be considered for calcium oxalate stone formers, especially those with hyperoxaluria. Specific recommendations for modifying the consumption of other nutrients cannot be made at this time because of the limited available information about the resultant effects. The aforementioned goals can be achieved within the context of a nutritionally balanced diet providing adequate sources of fruits and vegetables. There is a definite need for better designed studies of the nutritional effects on stone disease. This would promote a better understanding of the interplay between the genetic and environmental components of this disorder.     

Satisfaction with midwife-managed care in different time periods: a randomised controlled trial of 1299 women.

OBJECTIVE: To compare women's satisfaction with midwife-managed care with 'shared care' over three different time periods. DESIGN: Randomised controlled trial. SETTING: Glasgow Royal Maternity Hospital, Glasgow, UK. PARTICIPANTS: 1299 women experiencing normal pregnancy (consent rate: 82%). Six hundred and forty-eight women were randomised to midwife-managed care and 651 to 'shared care'. METHODS: Three self-report questionnaires were sent to women's homes. The questionnaires examined: satisfaction with antenatal care at 34-35 weeks' gestation, and satisfaction with intrapartum, hospital- and home-based postnatal care at seven weeks postnatally. The third questionnaire reviewed satisfaction with intrapartum care seven months after delivery. FINDINGS: Women in both groups were satisfied. However, women in the midwife-managed group were more highly satisfied in relation to the dimensions examined: relationships with staff, information transfer, choices and decisions, and social support. The differences between the two groups were evident for all time periods (i.e. antenatal, intrapartum and postnatal periods) and were sustained at seven-month follow-up. This is illustrated in the mean scores for relationships with staff, as measured at 34-35 weeks' gestation (possible range -2; very negative attitudes to 2; very positive attitudes). Women in the midwife-managed group scored a mean of 1.22 compared to 0.74 for the 'shared care' group (mean diff: 0.48; 95% CI: 0.42 to 0.55). While women in both groups were more likely to make positive rather than negative comments in open-ended questions, the midwife-managed group were more likely to make positive comments whereas the 'shared care' group were more likely to make negative comments. CONCLUSION: Midwife-managed care for healthy pregnant women which is integrated into existing services improves satisfaction with antenatal, intrapartum and postnatal care.     

Serial Transvaginal Ultrasonography Following McDonald Cerclage and Repeat Suture Insertion

Summary: The aim of this study was to explore the hypothesis that serial transvaginal ultrasonography identifies early evidence of suture failure and that repeat cerclage delays delivery. We undertook a review of our policy of transvaginal ultrasonographic cervical surveillance after McDonald cerclage and of repeat suture insertion if persistent cervical effacement developed. Data from 26 pregnancies in 26 women are analyzed. The women had had a total of 57 mid-trimester miscarriages with a median of 2 (1–6) mid-trimester losses per woman. Twelve (46%) of the 26 women developed cervical changes at scan and underwent repeat cerclage. All 14 women who had a single suture inserted progressed to live births but 1 of the 13 women who had repeat cerclage had a mid-trimester miscarriage (p>0.05). The median gestation at delivery for the women who had repeat cerclage was 35 (22–39) weeks compared with 38 (36–40) weeks for those who had a single suture (p>0.05). The median interval from the detection of cervical changes at scan to delivery was 13 (4–19) weeks. Serial transvaginal ultrasonography after cervical cerclage identifies a group of women who are more likely to deliver preterm, and provides an opportunity for intervention (repeat cerclage) which appears to delay delivery by an average of 7 weeks.     

Predictive value of minor anomalies. I. Association with major malformations

We examined 4305 white newborn infants for 114 minor physical features and major malformations to evaluate the hypothesis that the presence of three or more minor anomalies is highly predictive of a major malformation. We confirmed that the infant with three or more minor anomalies is at increased risk for a major malformation. However, this risk (19.6%) was much lower than the risk of 90% popularized by Smith and based on the study of Marden et al. (J Pediatr 1964;64:357). Analysis of the findings in the two studies showed that the lower predictive value was probably related to differences in study design. Nevertheless, some minor anomalies remain essential to the early recognition of several serious malformation syndromes.     

Cognitive and emotional processing in narratives of women abused by intimate partners

This study examined relationships between cognitive and emotional processing with changes in pain and depression among intimate partner violence survivors. Twenty-five women who wrote about their most traumatic experiences completed measures of pain and depressive symptoms before the first writing session and again 4 months following the last writing session. Reduced pain was significantly associated with less use of positive and negative emotion words. Relationships between cognitive and emotional aspects of writing with changes in depressive symptoms fell short of statistical significance. The results suggest that emotional processing in narrative writing predicts changes in pain in intimate partner violence survivors.
