BACKGROUND: To the authors' knowledge, placental site trophoblastic tumors occurring simultaneously in mother and infant have not previously been reported. PROCEDURE: The clinicopathologic features of metastatic placental site trophoblastic tumor in a mother and her 4-month-old son are described. RESULTS: The disease in the infant was aggressive, and he died in multiorgan failure within 5 weeks of hospital admission. Autopsy showed widespread metastases to liver, lungs, pleura, kidney, mesentery and lymph nodes. The mother, who had a uterine tumor and lung metastases, was treated with chemotherapy and hysterectomy and has no evidence of disease 26 months post-treatment. CONCLUSIONS: This report shows that placental site trophoblastic tumors can metastasize in both mother and child. 相似文献
A group of 15 elderly men and 14 young male students of physical education made twice a series of Taichiquan (TCQ) practices. Their electrocardiograms were recorded on tape-recorder and heart rates and heart rate variability (HRV) were calculated from digitized data. Here we report the results of recordings in supine positions before and after the first and second series of TCQ. Intervals between heart beats (RRIs) and their standard deviation (SDNN) increased in older men from recordings before the exercise to postexercise. In young subjects the SDNN and total variance (TV) of RRIs increased. HRV increases immediately after TCQ-exercise in young and old male healthy subjects. Whether these practices have permanent effects and effects in patients need controlled and prospective studies. 相似文献
Background: Although the prevalence of daily smokers are decreasing and there are signs of increasing stigma attached to smoking, occasional smoking rates have remained surprisingly stable. The increasing proportion of smokers who do not smoke daily emphasize the importance of understanding the reasoning behind this pattern of smoking. We explored how young adult occasional smokers in Norway viewed and defined their smoking and how they managed their smoker identities in a western context of tobacco denormalization.
Methods: 17 young adult occasional smokers (aged 24–31) were interviewed in-depth about smoking practices, attitudes towards smoking and occasional smoking in relation to self-presentation and social image.
Findings: The occasional smokers told detailed stories of how, when and in what situations they smoked, and in this, positioned their smoking as controlled and different from stigmatized daily smoking. Drinking situations were the most important context for occasional smoking, and they described occasional smoking and drinking alcohol in similar ways: as letting control go in a controlled way. Occasional smoking was positioned as a symbol of individualism and of transgression.
Conclusion: Strategies aiming at repositioning occasional smoking as uncool may be relevant to motivate occasional smokers to quit. Because alcohol plays such an important role in facilitating occasional smoking, extending smoke-free areas outside bars could also be a way to reduce occasional smoking. 相似文献
Aims: This study analyses how Finnish and Norwegian teenagers and parents of teenagers perceive the appropriateness, desirability or harmfulness of different drinking situations. The focus is on whether teenagers and parents perceive the situations similarly or differently.
Methods: Our data consist of focus group interviews from Finland and Norway with teenagers aged 14–17 years (n?=?8 groups, n?=?44 participants) and parents (n?=?8 groups, n?=?38). Three pictures portraying different drinking situations were presented to the participants, who were asked to describe (1) what kind of situation the picture depicts, (2) whether the way of drinking in the picture was acceptable or not and (3) whether they identified with the situation or not.
Findings: Our analysis showed that teenagers and parents defined the situations similarly and applied rather similar criteria when assessing the appropriateness of drinking. The most important criteria related to the amount and the way of drinking, and whether or not children were present in the situation. Regarding the identification with the situations, teenagers seemed to have somewhat stricter attitudes towards intoxication than adults, which can be perceived as a sign of an ongoing trend of decreasing youth drinking.
Conclusions: Overall, our analysis suggests that the alcohol worlds of parents and teenagers resembled each other, supporting the notion that the generational gap between parents and teenagers is diminishing. 相似文献
Tea made from the leaves of Rubus idaeus L. (raspberry) has been used for centuries as a folk medicine to treat wounds, diarrhoea, colic pain and as a uterine relaxant. Extracts of dried raspberry leaves prepared with different solvents, (n-hexane, ethyl acetate, chloroform and methanol) were tested in vitro for relaxant activity on transmurally stimulated guinea-pig ileum. The methanol (MeOH) extract exhibited the largest response and also indicated that the active compounds are of a relatively polar nature. Hence the bulk of the leaves were extracted with methanol and the dried extract fractionated on a silica gel column, eluting with chloroform, mixtures of chloroform and methanol and finally methanol. Each fraction was examined by thin layer chromatography and tested for relaxant activity in an in vitro transmurally stimulated guinea-pig ileum preparation. The fractions eluted with chloroform (CHCl(3)) lacked relaxant activity. Samples eluted with CHCl(3)/MeOH (95:5) had moderate relaxant activity, while a second distinctive peak of activity eluted with a more polar solvent mixture (CHCl(3)/MeOH 50:50) provided strong dose dependent responses. Evidence was obtained that there are at least two components of raspberry leaf extract which exhibit relaxant activity in an in vitro gastrointestinal preparation. 相似文献
This study aimed to characterize possible relationships between polymorphisms in the drug transporter genes organic anion transporting polypeptide-C (OATP-C, SLCO1B1), OATP-B (SLCO2B1), multidrug resistance-associated protein 2 (MRP2, ABCC2) and multidrug resistance transporter (MDR1, ABCB1) and the pharmacokinetics of pravastatin. We studied 41 healthy Caucasian volunteers who had previously participated in pharmacokinetic studies with pravastatin. Six volunteers had a very high pravastatin AUC value and were defined as outliers according to statistical criteria. The OATP-C gene was sequenced completely in all subjects, and they were also genotyped for selected single nucleotide polymorphisms (SNP) in the OATP-B, MDR1 and MRP2 genes. Of the six outliers, five were heterozygous for the OATP-C 521T>C (Val174Ala) SNP (allele frequency 42%) and three were heterozygous for a new SNP in the promoter region of OATP-C (-11187G>A, allele frequency 25%). Among the remaining 35 subjects, two were homozygous and six were heterozygous carriers of the 521T>C SNP (allele frequency 14%, P = 0.0384 versus outliers) and three were heterozygous carriers of the -11187G>A SNP (allele frequency 4%, P = 0.0380 versus outliers). In subjects with the -11187GA or 521TC genotype, the mean pravastatin AUC0-12 was 98% (P = 0.0061) or 106% (P = 0.0034) higher, respectively, compared to subjects with the reference genotype. These results were substantiated by haplotype analysis. In heterozygous carriers of *15B (containing the 388A>G and 521T>C variants), the mean pravastatin AUC0-12 was 93% (P = 0.024) higher compared to non-carriers and, in heterozygous carriers of *17 (containing the -11187G>A, 388A>G and 521T>C variants), it was 130% (P = 0.0053) higher compared to non-carriers. No significant associations were found between OATP-B, MRP2 or MDR1 polymorphisms and the pharmacokinetics of pravastatin. These results suggest that haplotypes are more informative in predicting the OATP-C phenotype than single SNPs. 相似文献
We surveyed the opinions of Finnish food business operators (FBOs) about the uniformity of local official food control and its importance for dairy, fishery and meat plants. A total of 136 FBOs responded to the questionnaire. Most FBOs considered official food control to be important for food safety and were generally satisfied with its quality. However, they often did not perceive official food control as being uniform, and 23% even considered it arbitrary. Small-sized FBOs were particularly critical of the relevance of control actions. The better the FBOs assessed their cooperation with the inspector, the higher they assessed the quality, uniformity and benefits of official food control. The cooperative approach in control practices should be emphasized to support the positive views of FBOs about official food control, thus promoting food safety. Cross-audits among local food control units are recommended to improve the FBOs’ experience of uniformity of food control. 相似文献
The aim of the study was to examine the construct validity of the Three-Factor Eating Questionnaire -R18 (TFEQ-R18), a measure
of eating behaviour, and to evaluate cognitive restraint, uncontrolled eating and emotional eating in a sample of adolescent
and young adult females of different weights. 相似文献
