Termination of pregnancy at 9-13 weeks' amenorrhoea with mifepristone and misoprostol

The effectiveness of a combined regimen of mifepristone and vaginal misoprostol for termination of pregnancies of 9-13 weeks of gestation was investigated in 120 UK abortion patients (median age, 22.1 years; median duration of amenorrhea, 10.3 weeks). Each woman received a single oral dose of 200 mg of mifepristone 36-48 hours before admission, at which time 800 mcg of misoprostol was administered vaginally. Where indicated, a further two doses of 400 mcg of misoprostol (vaginal or oral) were provided every 3 hours. All 120 women aborted on the day of prostaglandin administration; however, 6 women (5%) required exploratory curettage after the procedure for retained placenta. The median prostaglandin dose was 1200 mcg (range, 800-1600 mcg). The median time from misoprostol administration to abortion was 4.33 hours (range, 1.3-16.0 hours). 60 women (50%) required oral analgesics and 26 (22%) received parenteral analgesia. Diarrhea occurred in 38 women (32%). The median duration of bleeding after abortion was 12.5 days (range, 3-43 days). In questionnaires administered to 73 women, only 3 (4%) expressed dissatisfaction with medical abortion, because of pain or prolonged bleeding. The relatively high dose of misoprostol used in this study and the vaginal route of administration are presumed to account for the 95% success rate. Extension of medical abortion to later gestation times would decrease the need for surgery and expand women's choice of methods of pregnancy termination.     

Postpartum adjustment in first-time mothers: Relations between mood, maternal attitudes, and mother-infant interactions.

Self-report data were obtained from a middle-income sample of first-time mothers during pregnancy and at 1 and 3 months postpartum, and behavioral interactions between the mother and her infant were observed at 3 days and 1, 3, and 16 months postpartum. The main analyses revealed that pregnancy and postpartum mood states together explain a high proportion of the variance in mothers' maternal attitudes during the postpartum, although postpartum mood has the greater predictive power. Additionally, prior experience with children is significantly associated with maternal attitudes at all time points. Moreover, at both 1 and 3 months postpartum, depressed mothers, relative to nondepressed mothers, exhibit fewer affectionate contact behaviors toward their infants and are less likely to respond to infant vocalizations by vocalizing themselves, and, at 3 months, a higher proportion of the depressed mothers had started bottle-feeding their infants. Finally, differences in maternal behavior between depressed and nondepressed mothers during the early postpartum period were no longer apparent at 16 months postpartum. The implications of these findings are discussed with particular reference to the interrelations between prior child-care experience, mood, and maternal responsiveness.

Stress in Dairy Farming and the Adoption of New Technology.

Previous studies have identified a number of different farm stressors and have reported gender and age differences in levels of stress. This study aimed to determine stress experienced by New Zealand dairy farmers, particularly in relation to adoption of new technology and its relationship to age and gender. Measures of farm stress and adoption of technology were completed by 985 dairy farmers. The highest levels of stress were reported for time pressures, machinery breakdown, weather, and government policies. Stress related to new technologies occurred rarely. Women reported more stress and higher levels of stress for understanding new technologies. There was also an increase in severity of stress with age related to new technologies. Overall, stress levels were moderate and may reflect favorable economic conditions. The findings suggest a need to tailor stress interventions to meet specific needs.

Dimensions of perfectionism, daily stress, and depression: A test of the specific vulnerability hypothesis.

Tested whether perfectionism dimensions interact with specific stressors to predict depression. A depressed patient sample (N?=?51) and a general psychiatric sample (N?=?94) completed measures of perfectionism, hassles, and depression. Ss in Sample 2 also completed other personality measures to assess the amount of unique variance in depression. Partial support was obtained: In both samples, self-oriented perfectionism interacted only with achievement stressors to predict depression. Socially prescribed perfectionism interacted with interpersonal stress in Sample 1 and with achievement stress in Sample 2 to predict depression. Several personality variables, including socially prescribed perfectionism, accounted for unique variance in depression. The results suggest that perfectionism dimensions are associated with depression and may constitute specific vulnerability factors. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Perfectionism and relationship adjustment in pain patients and their spouses.

The authors assessed whether social facets of perfectionism were associated with indexes of dyadic and family adjustment. A sample of 83 pain patients and their spouses completed the Multidimensional Perfectionism Scale, Dyadic Adjustment Scale, Family Assessment Device, Beck Depression Inventory, and Multiaxial Pain Inventory. After controlling for depression, the authors found that pain patients' relationship adjustments were associated with their spouses' other-oriented perfectionism. Also, pain patients rated their other-oriented perfectionistic spouses as less supportive. Spouses' reports of poor dyadic and family adjustment were associated with their own socially prescribed perfectionism. The findings suggest that social aspects of perfectionism contribute to poor family adjustment. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Perfectionism and depression: Longitudinal assessment of a specific vulnerability hypothesis.

The authors tested whether perfectionism dimensions interact with specific stress to predict depression over time. A sample of 103 current and former patients completed measures of perfectionism and depression at Time 1 and measures of stress and depression 4 months later. After controlling for Time 1 depression, self-oriented perfectionism interacted only with achievement stress to predict Time 2 depression. Socially prescribed perfectionism did not interact with achievement or social stress to predict Time 2 depression, but it did predict Time 2 depression as a main effect. The results provide support for the contention that perfectionism dimensions are involved in vulnerability to depression over time. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Psychological distress and the frequency of perfectionistic thinking

Five studies tested the hypotheses that there are individual differences in the frequency of automatic thoughts involving perfectionism and that these thoughts are associated with psychological distress. Research with the Perfectionism Cognitions Inventory (PCI) established that this new measure has adequate psychometric properties, and high PCI scorers tend to spontaneously report perfectionistic thoughts in naturalistic situations. Additional research confirmed that frequent perfectionism thoughts account for unique variance in distress, over and above variance predicted by standard measures of negative automatic thoughts and trait perfectionism measures. Overall, the findings support the view that personality traits involved in depression and anxiety have a cognitive component involving ruminative thoughts and that activation of this cognitive personality component contributes to distress.     

Sentinel node localization in patients with breast cancer

BACKGROUND: Intraoperative lymphatic mapping and identification of the first draining lymph node (the sentinel node) may allow some patients with breast cancer to avoid the morbidity of formal axillary clearance. The aim of this pilot study was to establish the reliability of the technique in predicting axillary node status. METHODS: Sixty-eight consecutive patients with breast cancer, 38 undergoing mastectomy and 30 wide local excision, were included. Some 2-4 ml of 2.5 per cent Patent Blue dye was injected into adjacent breast tissue on the axillary side of the primary tumour. After 5-10 min, the axilla was explored. Blue-stained lymphatics were dissected to the sentinel node, which was removed for frozen-section examination, followed by routine histology. Formal axillary dissection was then completed. RESULTS: A sentinel lymph node was identified successfully in 56 (82 per cent) of 68 patients. Histology of the sentinel node accurately predicted axillary node status in 53 (95 per cent). There were three false negatives (5 per cent). In each case, only a single non-sentinel node was tumour positive. Sensitivity and specificity were 83 and 100 per cent respectively. CONCLUSION: This technique would allow a selective policy of formal axillary dissection in only node-positive patients; however, further experience and refinement are needed.

Solvent extraction of non-ferrous metals: A review 1972—1974

The research and development effort in the field of solvent extraction of non-ferrous metals for the period from mid 1972 to late 1974 has been reviewed. As well as sections on such metals as copper, nickel-cobalt, uranium, rare earths, molybdenum, tungsten, vanadium, chromium, cadmium and zinc, sections on secondary metal wastes and on acid extraction have been included. The review shows that copper is still the main metal of interest for treatment by solvent extraction but also clearly shows the rising interest in the nickel-cobalt area. Indeed half the review is concerned with the copper, nickel-cobalt developments. The extension of the application of the technique into the field of secondary metal processing is a development of considerable interest. The large number of references (225) is indicative of the intensity of the research and development effort and this review should provide a quick and reliable source of reference for those wishing to keep abreast of this rapidly developing area of hydrometallurgy.
